In some possible implementation embodiments provided by the present invention, as shown in FIG. 1 , FIG. 2 and FIG. 3 , the base station further includes a float assembly 110 , a non-contact sensing element 130 and a non-contact sensed element 140 , wherein the float The assembly 110 is arranged inside the water tank assembly 200, and includes a float body 111 that can float under the action of the liquid, that is, the float body 111 floats up and down with the rise or fall of the liquid surface, and the float body 111 can float on the surface of the liquid under the action of the liquid. liquid surface. The non-contact sensing element 130 is used to detect the non-contact sensed element 140. For example, the non-contact sensing element 130 is used to detect the signal parameters emitted by the non-contact sensed element 140. One of the contact-type sensed elements 140 is disposed on the float body 111 , and the other is disposed separately from the water tank assembly and located on the base station body, that is, one of the non-contact type sensed element 130 and the non-contact sensed element 140 follows. The float body 111 moves while floating, and the other is set at a fixed position outside the water tank assembly 200, for example, the other is set at the to-be-installed position of the water tank assembly 200 on the base station body, so that the float body 111 floats up and down under the action of the liquid During the process, the signal parameters detected by the non-contact sensing element 130 emitted by the non-contact sensing element 140 are different, and then the liquid level range in the water tank assembly 200 can be determined according to the different signal parameters, and the water tank assembly 200 can be determined. current position. For example, when the water tank assembly 200 is installed on the base station body, and the liquid surface in the water tank assembly 200 is at a specific position, the non-contact sensing element 130 can sense the signal parameters transmitted by the non-contact sensing element 140, indicating that the water tank assembly 200 is correct It is installed on the base station body, and the liquid surface in the water tank assembly 200 reaches a specific position, that is, a set of detection devices such as the float assembly 110, the non-contact sensing element 130, and the non-contact sensing element 140 can simultaneously detect the water tank assembly 200. Compared with the liquid level detection device in the related art, which can only detect the liquid level in the water tank assembly 200 and cannot detect the current position of the water tank assembly 200, it is more enlarged. The function of the float assembly 110 is improved, and at the same time, compared with the use of two sets of detection devices to realize the liquid level detection in the water tank assembly 200 and the current position detection of the water tank assembly 200 in the related art, the setting of one set of detection devices is simplified, that is, the The structure of the product simplifies the system software program and algorithm, which can effectively save costs and is suitable for popularization and application.

Further, on the one hand, the non-contact sensed element 140 is disposed on the float body 111, and the non-contact sensing element 130 is disposed on the base station body. On the other hand, the non-contact sensing element 130 is disposed on the float body 111, The contact-type sensed element 140 is disposed on the base station body. The different arrangement positions of the non-contact sensed element 140 and the non-contact inductive element 130 can meet the requirements of different structures and performances of the non-contact sensed element 140 and the non-contact inductive element 130, thus expanding the use range of the product. It can be understood that the non-contact sensed element 140 may include a magnetic element, a light emitting element or other components that meet the requirements, and the non-contact sensing element 130 may include a magnetic induction element, an optical induction element or other components that meet the requirements. The non-contact sensed element 140 or the non-contact sensing element 130 disposed on the float body 111 may be located inside or outside the float body 111 , or at other positions that meet requirements, which are not specifically limited in the present invention.

Further, the water tank assembly 200 may be a clean water tank for accommodating cleaning liquid, or a sewage tank for accommodating dirty liquid. Due to the different functions of the water tank assembly, the float body 111, the non-contact sensing element 130, the The location of the contact-type sensing element 140 is also different. For example, the liquid in the clean water tank is mainly used to clean the cleaning part or supply liquid to the liquid storage tank, that is, the liquid in the clean water tank will become less and less during the working process. Therefore, it is necessary to ensure that there is a certain amount of liquid in the clean water tank. The liquid can act on the cleaning section and/or the liquid storage tank, that is, it is necessary to detect when the fresh water tank is short of liquid. Therefore, the float body 111 can be arranged on the bottom wall or side wall of the clean water tank, and one of the non-contact sensing element 130 and the non-contact sensing element 140 can be arranged on the base station body and close to the bottom wall of the water tank, so that , when the clean water tank assembly 200 is installed on the base station body, and the liquid level in the clean water tank reaches a specific position, the non-contact sensing element 130 can sense the non-contact sensed element 140, indicating that the clean water tank group 200 is correct It is installed on the base station body, and there is less liquid in the water tank assembly, so it needs to be replenished in time.

For another example, the sewage tank is mainly used to collect the sewage during the cleaning process, that is, the liquid in the sewage tank will increase during the operation of the cleaning equipment, in order to avoid the overflow of the liquid in the sewage tank and affect the reliability of the cleaning equipment or For the cleaning effect, it is necessary to detect when the recovery tank is full of liquid. Therefore, the float body 111 can be arranged on the top wall or side wall of the clean water tank, and one of the non-contact sensing element 130 and the non-contact sensed element 140 can be arranged on the base station body and close to the top wall of the water tank, so that , when the clean water tank assembly 200 is installed on the base station body, and the liquid level in the clean water tank reaches a specific position, the non-contact sensing element 130 can sense the non-contact sensed element 140, indicating that the clean water tank assembly 200 is correctly installed On the base station body, and the liquid in the water tank assembly 200 is full, the liquid in the sewage tank needs to be dumped out in time.

In some possible implementation embodiments provided by the present invention, the non-contact sensed element 140 includes a magnetic element, and the non-contact sensing element 130 includes a Hall sensor, such as a magnetic induction element. The magnetic element is arranged on the float body 111, and the Hall sensor is arranged on the base station body. Specifically, the magnetic member can be arranged inside the float body 111, and this arrangement can prevent the magnetic member from being disposed outside the float body 111, which may cause liquid to wet the magnetic member and corrode it, cause malfunction, and interfere with the signal emission intensity. problem, which is beneficial to improve the service life of the magnetic component and the stability and reliability of the transmitted signal.

That is to say, in the base station provided by the embodiment of the present invention, the float assembly 110 is disposed inside the water tank assembly 200, the magnetic element is disposed inside the float body 111 located inside the water tank assembly 200, and the Hall sensor is disposed on the base station body, and the liquid Under the action of , when the magnetic element floats to the detection range of the Hall sensor, it means that the liquid level in the water tank assembly 200 reaches a certain height, and the water tank assembly 200 is correctly installed on the base station body, wherein the designated height can be 10mm, 20mm, 30mm, 50mm or other values or ranges that meet the requirements, if the water tank assembly 200 is correctly installed on the base station body, the water tank assembly 200 can be reliably and accurately connected to the base station body.

It can be understood that, in the base station provided by the embodiment of the present invention, the float assembly 110 is arranged inside the water tank assembly 200, a magnetic member is arranged inside the float body 111, and a Hall sensor is arranged on the base station body. During the floating process of the body 111, the positions of the magnetic element and the float body 111 are fixed, and the Hall sensor can detect signals of different parameters emitted by the magnetic element. It can be the preset threshold value of the magnetic element emission signal received by the Hall sensor, so that when the signal parameter emitted by the magnetic element received by the Hall sensor reaches the preset threshold value, the liquid level in the water tank assembly 200 reaches the specified height, and The water tank assembly 200 is correctly installed on the base station body, that is, the magnetic element can follow the float body 111 to float within the detection range of the Hall sensor. Therefore, by reasonably setting the positions of the magnetic element and the Hall sensor, and the detection range of the Hall sensor, and cooperating with the float assembly 110, the liquid level in the water tank assembly 200 and whether the water tank assembly 200 is in place can be detected. The structure is simple, the realization is easy, the cost is low, and the utility model is suitable for popularization and application. Wherein, the detection range of the magnetic induction element is shown as P in FIG. 2 and FIG. 3 .

Specifically, the magnetic element can be a magnetic strip, a magnetic ring, or other magnetic structures that meet the requirements, and the Hall sensor can be a magnetic induction sensor or other structures that meet the requirements. Other structures required.

Further, the number of Hall sensors can be one, two or more, and two or more Hall sensors are arranged at different positions of the base station body, which can sense the liquid surfaces of different heights in the water tank assembly 200 to reach different heights. The specific position, that is, the liquid surface of different heights in the water tank assembly 200 can be detected, which expands the use range of the product.

In some possible implementation embodiments provided by the present invention, the base station further includes a controller, and the non-contact sensing element 130 is electrically connected to the controller of the base station, so as to output the sensing result to the controller. It can be understood that the controller of the base station can also interact with the information of the cleaning robot or the remote control terminal (APP). In this way, it is convenient for the controller to reasonably control other components of the cleaning system according to the sensing result of the non-contact sensing element 130. For example, according to the sensing result, adjust the position of the water tank assembly 200 to correctly install the water tank assembly 200 on the base station body. As a result, the water tank assembly 200 is replenished in time to ensure that the liquid in the water tank assembly 200 can reliably and fully act on the cleaning part and/or the liquid storage tank, and the cleaning equipment can also be controlled to stop working according to the sensing results to avoid sewage in the water tank assembly 200. More and overflow, which greatly improves the reliability of the cleaning system.

In some of the above embodiments, as shown in FIGS. 6 , 7 and 8 , the float assembly 110 further includes a mounting bracket 112 and a connecting portion 113 . The mounting bracket 112 is disposed inside the water tank assembly 200 and is detachable from the water tank assembly 200 . One end of the connecting part 113 is connected with the mounting frame 112 in rotation, and the other end is connected with the float body 111, that is, under the action of the liquid, the connecting part 113 can swing relative to the mounting frame 112 in the up and down direction, that is, the connecting part 113 can swing relative to the mounting bracket 112 toward the bottom wall of the water tank assembly 200 and away from the bottom wall of the water tank assembly 200 , thereby driving the magnetic member to swing up and down relative to the bottom wall of the water tank assembly 200 .

Since the mounting bracket 112 is detachably connected to the water tank assembly 200, that is, the float assembly 110 can be assembled into different water tank assemblies 200 through the mounting bracket 112, and the non-contact sensing element is The sensing element 130 can detect the liquid level and current position in different water tank assemblies 200, that is, the float assembly, the non-contact sensed element 130, and the non-contact sensing element 140 can be regarded as a liquid level detection device as a whole, and can As a standardized module, it is configured in the corresponding product or scene, which expands the use range of the liquid level detection device. Meanwhile, the setting of the mounting bracket 112 facilitates the user to disassemble the float assembly 110 from the water tank assembly 200 for maintenance and cleaning, which greatly improves the user's experience.

Specifically, the mounting bracket 112 is provided with a through hole, and the connecting portion 113 is provided with a mounting hole. The connecting portion 113 and the mounting bracket 112 can be rotatably connected by passing the connecting piece 150 through the mounting hole and the through hole. Specifically, the connecting piece 150 The axis of rotation of the connecting portion 113 relative to the mounting bracket 112 is parallel to the plane where the bottom wall of the water tank assembly 200 is located, such as the axis of the rotating shaft and the bottom wall of the water tank assembly 200. The planes are parallel, so that the connecting portion 113 can only swing approximately in the vertical direction relative to the mounting bracket 112 .

Because the float body 111 floats under the action of the liquid and drives the connecting portion 113 to rotate relative to the mounting frame 112, and at the same time drives the magnetic member to swing relative to the bottom wall of the water tank assembly 200 in the vertical direction. At least one is provided with a limit portion 114, and the limit portion 114 is used to limit the rotation range of the connecting portion 113 relative to the mounting frame 112, thereby realizing the limit of the swing of the magnetic member relative to the bottom wall of the water tank assembly 200 in the up-down direction. , so that the liquid level in the water tank assembly 200 reaches the specified height, and when the water tank assembly 200 is installed on the base station body, the magnetic parts can accurately and reliably float to the detection range of the Hall sensor under the driving of the float body 111, that is, the limit The setting of the position portion 114 enables the magnetic member to float within the detection range of the Hall sensor when the liquid level in the water tank assembly 200 reaches a preset height and the water tank assembly 200 is installed on the base station body, so that a set of Hall sensors can be used. By cooperating with the magnetic element and the float assembly, the liquid level detection in the water tank assembly 200 and the detection of whether the water tank assembly 200 is in place can be realized, and the accuracy and reliability of the detection results are ensured, the structure is simple, and the cost is low, Suitable for promotion and application.

It can be understood that the limiting portion 114 can be disposed on one of the mounting frame 112 or the connecting portion 113, or can be provided on the mounting frame 112 and the connecting portion 113 at the same time. The different setting positions of the limiting portion 114 can satisfy the limiting The requirements of the different structures of the bit portion 114.

Further, the limiting portion 114 includes a baffle plate disposed on the mounting frame 112 . The baffle plate is located above the connecting portion 113 and between two ends of the connecting portion 113 , that is, the baffle plate is located between the connecting portion 113 and the mounting frame 112 . Between one end of the connection and the other end connected to the float body 111 , the float body 111 floats upward under the action of the liquid and drives the connection part 113 to the direction away from the bottom wall of the water tank assembly 200 relative to the mounting bracket 112 During the swinging process, the connecting portion 113 can abut against the baffle, that is, after the float body 111 abuts against the baffle, it will not float up as the liquid level increases, but only sink as the liquid level decreases. Since the magnetic member is disposed inside the float body 111 , the position of the magnetic member relative to the float body 111 is fixed during the floating process of the float body 111 . Since the position of the water tank assembly 200 is fixed, the height of the liquid level when the connecting portion 113 is in contact with the baffle is defined as the specified height. In this state, the detection range of the Hall sensor is reasonably limited to make the water tank After the assembly 200 is correctly installed to the structure to be installed, the magnetic element is located within the detection range of the Hall sensor, and then through the Hall sensor, both the liquid level height in the water tank assembly 200 can be detected, and whether the water tank assembly 200 is correct can be detected. It is installed on the structure to be installed for detection, and the structure is simple and the manufacturing cost is low.

For example, the water tank assembly 200 in the embodiment of the present invention is a clean water tank, the water tank assembly 200 is applied to the base station of the cleaning system, and the water tank assembly 200 is detachably installed on the base station body, wherein the Hall sensor is disposed on the base station body, The mounting frame 112 of the float assembly 110 is fixed on the bottom wall of the water tank assembly 200 , one end of the connecting portion 113 is rotatably connected to the mounting frame 112 through a rotating shaft, the other end of the mounting frame 112 is connected with the float body 111 , and the magnetic member is arranged on the float body 111 Inside, the float body 111 is a low-density material. When the float body 111 is immersed in the liquid and receives buoyancy, it will rotate around the rotating shaft and drive the magnetic piece to swing relative to the mounting frame 112. After the position of the float body 111 changes, the surrounding For the change of the magnetic field strength, the Hall sensor determines the change of the liquid level in the water tank assembly 200 and/or the current position of the water tank assembly 200 through the received change information. By disposing the limiting portion 114 on the mounting frame 112 , the limiting portion 114 limits the rotation of the connecting portion 113 , and when the liquid level in the water tank assembly 200 reaches a specified height, the connecting portion 113 abuts the limiting portion 114 . Therefore, as shown in FIG. 2 and FIG. 4 , if the magnetic element floats within the detection range of the Hall sensor, that is, the Hall sensor detects that the magnetic element floats within the detection range P, it means that the height of the liquid in the water tank assembly 200 reaches the preset level. height, and the water tank assembly 200 is installed in place, it can be understood that the controller of the base station is electrically connected to the Hall sensor, and at this time the Hall sensor can send a corresponding signal to the cleaning system, telling the cleaning equipment, and/or the base station body, And/or the water tank assembly 200, there is liquid in the water tank assembly 200, the liquid reaches a specified liquid level, and the water tank assembly 200 is accurately installed on the base station body.

When the float body 111 is a hollow structure, the space of the installation cavity is larger than the outer dimension of the contactless sensing element 130 or the contactless sensing element 140 , so that the contactless sensing element 130 or the contactless sensing element 140 Installed in the installation cavity, after the cover body 116 covers the base body 115 , there is a gap between the non-contact sensing element 130 or the non-contact sensed element 140 and the cover body 116 and the base body 115 , and the float body 111 is a hollow structure. It can be understood that the non-contact sensing element 130 or the non-contact sensing element 140 may not be provided in the installation cavity, that is, the float body 111 is a hollow structure and the float assembly 110 is not provided with the non-contact sensing element 130 or the non-contact sensing element 140 . The type is sensed element 140 .

In some possible implementation embodiments provided by the present invention, as shown in FIG. 7 , at least one of the connecting portion 113 and the float body 111 is provided with an anti-installation and anti-reversal structure 120. The installation of the anti-installation and anti-reversal structure 120 can avoid connection The float formed by the connecting part 113 and the float body 111 is assembled in the opposite direction relative to the mounting bracket 112. For example, the anti-installation and anti-reversal structure 120 can prevent the float formed by the connecting part 113 and the float body 111 from being installed inversely relative to the bottom wall of the water tank assembly 200, thereby preventing Avoid the change of the position of the non-contact sensing element 130 or the non-contact sensed element 140 installed on the float body 111 relative to the bottom wall of the water tank assembly 200 to affect the detection of the liquid level in the water tank assembly 200 and the presence of the water tank assembly 200 accuracy.

Wherein, the anti-installation and anti-reverse structure 120 can be arranged on the float body 111, on the connecting portion 113, or on the float body 111 and the connecting portion 113 at the same time. Requirements for different structures of the connecting portion 113 and the float body 111 . For example, when the base body 115 of the float body 111 and the connecting portion 113 are integrally formed, the anti-reversal structure 120 is provided on the connecting portion 113 to prevent the float body 111 from being reversely installed relative to the water tank assembly 200 . It can be understood that the anti-installation and anti-reversal structure 120 can also be directly disposed on the float body 111 to prevent the float body 111 from being installed inversely with respect to the water tank assembly 200, or the anti-installation and anti-reversal structure 120 can be simultaneously disposed on the float body 111 and connected to the water tank assembly 200. On the part 113 , it serves as a double reminder to prevent the float body 111 from being reversely installed relative to the water tank assembly 200 .

Further, the base body 115 and the connecting portion 113 are integral structures, and the anti-installation and anti-reverse structure 120 includes a second protruding structure disposed at the bottom of the connecting portion 113 . The bottom wall of the water tank assembly 200 is reversely installed, and the second protruding structure is convenient to process and easy to implement, and there is no problem of water accumulation, and has a good reminder effect, which is suitable for popularization and application.

It can be understood that the number of the drainage holes 119 may be one, two or more, and the drainage holes 119 may be circular holes, square holes, or other shapes that meet requirements, which are not specifically limited in the present invention.

Further, the top of the float body 111 of the float assembly 110 is a curved surface. For example, the float body 111 is a cylindrical structure, a spherical structure, or other structures that meet the requirements. The top, taking the spherical structure as an example, any surface of the spherical structure is the top of the float body 111 , so that the float body encounters less resistance to water during the floating process, which is beneficial to improve the detection sensitivity, and at the same time, The curved surface can guide the liquid, thereby avoiding the situation of water accumulation on the top of the float body 111 , which is beneficial to further improve the quality of the liquid in the box body.

The float body 111 and the connection part 113 together form a float, and the float is made of low-density material, that is, the float body 111 and the connection part 113 are both low-density material parts to ensure that the float body 111 and the connection part 113 are under the action of the liquid able to float on liquid surfaces. It can be understood that, the materials of the float body 111 and the connecting portion 113 may be the same or different, which are not specifically limited in the present invention.

In some possible embodiments provided by the present invention, as shown in FIG. 9 , FIG. 10 and FIG. 11 , the water tank assembly 200 includes a lower shell 210 , an upper shell 220 and a handle 230 , wherein the top of the lower shell 210 is provided with a The opening, the lower case 210 includes a first installation structure 211, and the upper case 220 is pivotally connected with the first installation structure 211, and can open and close the opening. That is to say, the water tank assembly 200 provided by the present invention is a combined water tank. The water tank is composed of the upper shell 220 and the lower shell 210. When the upper shell 220 closes the opening of the lower shell 210, the liquid can be contained in the upper shell. 220 and the lower shell 210 to form a closed space to ensure that the liquid is not spilled. When the upper case 220 opens the opening of the lower case 210 , the liquid in the lower case 210 can be poured out by turning or tilting the lower case 210 .

The upper shell and the lower shell form a closed space for accommodating liquid, and the float assembly 110 is arranged in the closed space. According to whether the water tank assembly is a clean water tank or a sewage tank, the position of the float assembly 110 can be reasonably set. Specifically, the float assembly 110 is disposed inside the lower shell 210, the float assembly is fixed inside the lower shell 210 through the mounting bracket 112, such as being fixed on the bottom wall or side wall of the lower shell 210, one end of the connecting portion 113 is rotatably connected with the mounting bracket 112, The other end is connected with the float body 111, so that under the action of the liquid, the float body 111 can float on the surface of the liquid. The non-contact sensed element 140 is disposed on the float body 111, and the non-contact sense element 130 is disposed on the base station body, so that the float body 111 floats under the action of the liquid and drives the non-contact sensed element 140 to float, through the non-contact sensing element 140. The range of the signal sensed by the contact sensing element 130 or the presence or absence of the signal can determine the liquid level in the lower shell 210, and can determine whether the lower shell 210 is installed in place. It can be understood that the float assembly 110 may also be disposed on the side wall of the lower shell 210, or on the side wall of the upper shell 220 or the top wall of the upper shell 220, which is not specifically limited in the present invention.

Further, the handle 230 includes a handle portion 232 and transition portions 231 located at both ends of the handle portion 232 . The transition portion 231 is rotatably connected to the lower case 210 , thereby driving the handle portion 232 to rotate relative to the lower case 210 . The user can use the handle portion 232 to rotate Lifting the water tank assembly 200 to carry the water tank assembly 200 is simple to operate and convenient to use. Since the handle 230 provided in the embodiment of the present invention is rotatably connected with the lower shell 210 , the handle 230 is not rotatably connected with the upper shell 220 , this arrangement can effectively prevent the user from picking up the water tank assembly 200 through the handle 232 . However, because the connection between the upper shell 220 and the lower shell 210 is unreliable and not locked, the lower shell 210 is separated from the upper shell 220, and the lower shell 210 is inclined to cause the liquid to spill out. The reliability of the transportation of the water tank assembly 200 is beneficial to avoid waste of liquid resources.

In this embodiment, a limiting device 213 may also be provided on the outer side wall of the lower shell 210, and the limiting device 213 can limit the rotation of the transition portion 231 relative to the lower shell 210 toward the first installation structure 211, that is, limit The positioning device 213 can limit the range of rotation of the transition portion 231 to the first installation structure 211 , and this arrangement can prevent the transition portion 231 from rotating towards the first installation structure 211 , the rotation range is large and the hand-held portion is located in the lower shell. The peripheral side of 210, for example, the hand-held portion is located on the peripheral side of the lower shell 210 below the first installation structure 211, so that after the upper shell 220 is opened, the upper shell 220 blocks the hand-held portion on the peripheral side of the lower shell 210, which is not conducive to holding the hand-held portion 210. The water tank assembly 200 is moved to the top of the lower shell 210 by the hand-held part, which hinders the user to perform operations such as pouring, replenishing, and transporting the water tank assembly 200 by using the hand-held part. That is to say, in the embodiment of the present invention, the limiter 213 is used to limit the rotation range of the transition portion 231 toward the first installation structure 211 , so that the maximum rotation range of the grip portion 232 toward the first installation structure 211 is when the grip portion 232 is located in the lower shell 210 . In this way, when the upper shell 220 is opened, the upper shell 220 rotates to the rear wall of the lower shell 210, and the holding portion 232 is located above the lower shell 210, so that it is convenient for the user to pick up the water tank assembly 200 through the holding portion 232. It is easy to operate and easy to use.

In some possible implementation embodiments provided by the present invention, as shown in FIG. 10 , the lower shell 210 is provided with a second installation structure 212 connected with the transition portion 231 , that is, the transition portion 231 of the handle 230 passes through the second installation structure 212 is rotatably connected to realize the rotation of the handle 230 relative to the lower shell 210, and the limiting structure 215 includes a limiting inclined plane between the second mounting structure 212 and the first mounting structure 211, so that the transition portion 231 moves closer to the first mounting structure 211. During the rotation of the structure 211 , the transition part 231 will abut with the limiting slope so that the holding part 232 is located above the lower shell 210 , that is, the holding part 232 is prevented from rotating to the circumference of the lower shell 210 close to the first installation structure 211 . side situation occurs. It can be understood that when the handle 230 is in a free state, the following two situations will occur due to the influence of gravity. The first situation is that the transition portion 231 is in contact with the limiting device 213 , and the second situation is that the gripping portion 232 is in contact with the lower portion. The side wall of the casing 210 away from the first installation structure 211 abuts against. Among them, in the first case, it is convenient for the user to directly lift the water tank assembly 200 through the handle portion 232 , and in the second case, the water tank assembly 200 occupies a small space and is convenient for storage. Wherein, when the user needs to turn the upper shell 220 to open the opening of the lower shell 210, if the handle 230 is in the second situation, the user can directly rotate the upper shell 220 to open the opening of the lower shell 210, if the handle 230 is in the first situation In this case, the user needs to rotate the handle 30 to the second condition, and then rotate the upper case 220 to open the opening of the lower case 210 . In this way, even if the upper shell 220 opens the opening of the lower shell 210, the user can quickly, smoothly and conveniently pick up the water tank assembly 200 through the handle 232, which is convenient to operate and greatly improves the user's operating experience. The limiting slope has a simple structure and is convenient for processing, which is beneficial to reduce the manufacturing cost of the water tank assembly 200 and is suitable for popularization and application.

The limiting slope is inclined downward from the direction of the first installation structure 211 to the second mounting structure 212 , so that after the transition portion 231 is in contact with the limiting slope, the holding portion 232 can be reliably and stably located above the lower shell 210 , preventing In order to rotate the handle portion to the peripheral side of the lower case 210, there is a problem that after the upper case 220 opens the opening of the lower case 210, it prevents the user from picking up the water tank assembly 200 through the handle portion 232, so that the user can easily and quickly pass through the water tank assembly 200 located above the lower case 210. The grip portion 232 picks up the water tank assembly 200 . It can be understood that, by reasonably setting the inclination angle of the limiting slope, it is possible to adjust the specific position of the grip portion 232 above the lower shell 210 after the transition portion 231 is in contact with the limiting slope, so that the user's hand can be quickly, accurately and conveniently located. Hold the grip portion securely, and pick up the water tank assembly 200 through the grip portion 232 .

Further, the number of transition parts 231 may be two, the two transition parts 231 are located at two ends of the holding part 232 respectively, and the two transition parts 231 are respectively connected to the two second installation structures 212 on opposite sides of the lower shell 210 through the two transition parts 231 . The rotational connection enables the grip portion 232 to rotate relative to the lower case 210 . The number of the limiting devices 213 may be one or two. If the number of the limiting devices 213 is one, one limiting device 213 may be located between any second installation structure 212 and the first installation structure 211 , if the number of the limiting devices 213 is two, each limiting device 213 is located between a second mounting structure 212 and a first mounting structure 211 .

In the above embodiment, as shown in FIG. 10 , the top end of the lower shell 210 is provided with a boss structure 214 protruding outward, and the first mounting structure 211 and the second mounting structure 212 are arranged on the boss structure 214 to avoid the first The first mounting structure 211 and/or the second mounting structure 212 are directly disposed on the outer side wall of the lower case 210 to affect the strength of the side wall of the lower case 210. The arrangement of the boss structure 214 is beneficial to improve the overall strength of the lower case 210 and improve the The reliability of the connection between the lower case 210 and the upper case 220 , and the reliability of the connection between the handle 230 and the lower case 210 . The limiting device 213 includes a protruding structure arranged on the boss structure 214 , and a limiting slope is arranged on the side of the protruding structure close to the upper shell 220 . On the stage structure 214 , the influence of the limiting device 213 on the strength of the side wall of the lower case 210 is reduced, which is beneficial to further improve the reliability of the lower case 210 .

In some possible implementation embodiments provided by the present invention, the second mounting structure 212 includes a mounting hole, the transition portion 231 includes a transition portion, a rotating portion and a convex portion connected in sequence, and one end of the transition portion away from the rotating portion and the grip portion 232 Connecting, the rotating part passes through the installation hole and can rotate in the installation hole, that is, the rotating part can rotate relative to the lower shell 210 , and then drives the holding part 232 to rotate relative to the lower shell 210 through the rotating part and the transition part. Since the protruding portion is clamped on the side of the mounting hole away from the transition portion, in the process that the rotating portion drives the protruding portion to rotate synchronously, the restriction of the protruding portion will not cause the rotating portion to detach from the mounting hole, that is, the protruding portion and the rotating portion will not be separated from the mounting hole. The disposition of the lower shell 210 enables the handle 230 to rotate relative to the lower shell 210 and does not disengage from the mounting hole of the lower shell 210, that is, the handle 230 is locked on the lower shell 210, which improves the connection between the handle 230 and the lower shell 210. reliability.

Further, there is a gap between the rotating portion and the mounting hole, so that the rotating portion can both rotate and slide in the mounting hole. This arrangement improves the flexibility of the handle 230 to rotate relative to the lower case 210 .

In some possible implementation embodiments provided by the present invention, as shown in FIG. 11 , the water tank assembly 200 further includes a handle position 240 , and the handle position 240 is disposed on the outer bottom wall of the lower case 210 and/or the outer side of the lower case 210 The wall, the setting of the handle position 240 enables the user to carry or operate the water tank assembly 200 by holding the handle position 240, or the handle position 240 and the handle 232, for example, when the upper case 220 is opened and the lower case 210 is opened. , the user can hold the gripping position 240 and the holding portion 232 respectively, and then the liquid in the lower shell 210 can be poured, which is easy to operate and easy to use. On the one hand, the handle position 240 is disposed on the outer bottom wall of the lower case 210 , on the other hand, the handle position 240 is disposed on the outer side wall of the lower case 210 , and on the other hand, the handle position 240 includes an outer wall respectively disposed on the lower case 210 . The two bottom wall and the outer side wall, different arrangement positions and different numbers of the handle positions 240 can meet the needs of different structures of the handle positions 240 and the needs of different users, thus expanding the use range of the product.

Further, since the upper case 220 and the lower case 210 are pivotally connected by the first installation structure 211 , after the upper case 220 opens the opening of the lower case 210 , the opening space of the part of the opening away from the first installation structure 211 is larger. Therefore, when the upper case 220 opens the opening of the lower case 210 When the handle position 240 is disposed on the outer bottom wall of the lower case 210, the handle position 240 is disposed close to the first installation structure 211, and when the handle position 240 is disposed on the outer side wall of the lower case 210, the handle position 240 is located in the first installation structure Below 211, set in this way, when the user holds the handle 240 and tilts the lower shell 210, the liquid in the lower shell 210 can quickly flow out through the part of the opening away from the first installation structure 211, that is, the liquid passes through a larger open space. Part of the openings flow out, which is beneficial to improve the pouring efficiency of the liquid and improve the user's satisfaction.

Further, the latching position 240 and the lower shell 210 may have a one-piece structure or a separate structure, and different arrangements of the latching position 240 and the lower casing 210 can meet the requirements of different structures of the latching position 240 . For example, on the one hand, the latching position 240 includes a groove structure formed on the lower shell 210 , for example, the latching position 240 includes a groove structure formed on the outer bottom wall of the lower casing 210 and/or formed on the outer side wall of the lower casing 210 The groove structure is convenient for processing and the cost is low. On the other hand, the handle 240 includes a handle insert connected with the lower shell 210 , for example, the handle insert is connected with the outer bottom wall and/or the outer bottom wall of the lower case 210 and/or by means of insert connection, plug connection, snap connection, etc. The outer side walls of the lower shell 210 are connected, and specifically, the snap-in inserts can be plate-like structures, rod-like structures, or other structures that meet requirements.
