So, can effectively reduce adnexed bacterium quantity on the round brush, avoid bacterial growing to produce the peculiar smell to user's use experience can be improved.

For a better understanding, specific structures and effects of the cleaning system of the present disclosure will be described in detail below with reference to fig. 1 to 11 of the drawings attached to the specification in conjunction with specific embodiments.

Referring to fig. 1, in the present embodiment, the cleaning system includes a hand-held cleaning device 1 and a base station 2. Wherein the hand-held cleaning device 1 comprises a body assembly 15, a floor brush assembly 11 rotatably connected to the body assembly 15. The body assembly 15 includes a body 16 and functional components such as a clean water tank, a dirty water tank, etc. disposed on the body 16, and the floor brush assembly 11 is configured to contact a work surface such as the floor to clean the floor. The body assembly 15 is rotatably connected with the floor brush assembly 11, so that a user can adjust the rotation angle between the body assembly 15 and the floor brush assembly 11, etc. as required, and the disclosure is not specifically described herein.

The clean water tank is configured to supply liquid to the area where the roll brush 13 is located under the control of the water pump so that the roll brush 13 can be washed in the wash tank 22 when the cleaning system performs a self-cleaning operation. Meanwhile, the main motor inside the body assembly 15 sucks the sewage into the sewage tank when the roll brush 13 is cleaned. And repeating the steps, and stopping the water pump to operate the water tank to finish water supply after multiple times of water cleaning.

Referring to fig. 1 and 3, the floor brush assembly 11 includes a floor brush housing 12, a roll brush 13 disposed at a front side edge of the floor brush housing 12, and rollers 14 disposed at left and right sides of the floor brush housing 12.

In detail, the roll brush 13 is capable of performing a spinning motion under the control of the motor. During the cleaning operation of the hand-held cleaning appliance 1 by the user, a part of the surface of the roller brush 13 is configured to engage with the work surface to be cleaned, and the roller brush 13 is constantly in a spinning motion during this operation. The working surface to be cleaned is continuously rotated and rubbed by rolling.

The rollers 14 are provided in two, respectively at the left and right sides of the rear of the floor brush housing 12, and the rollers 14 are controlled by a driving means such as a motor and configured to be attached to the work surface to be cleaned, and can assist the hand-held cleaning device 1 to move on the work surface to be cleaned when the driving means drives the rollers 14 to rotate.

Referring to fig. 3, the base station 2 in the cleaning system is configured for placing the hand-held cleaning device 1. In order to allow a stable placement of the hand-held cleaning device 1, tilting or shaking thereof is avoided. The end face of the base 21 of the base station 2 may be configured to a shape that fits the bottom of the floor brush assembly 11.

Referring to fig. 4, a base 21 of the base station 2 is provided with a cleaning tank 22, an accommodating portion 24, a stopper portion 211, and a charging unit 25. Wherein, a UV light assembly 23 is arranged in the cleaning tank 22. Wherein the receptacle 24 is configured for receiving cleaning accessories, such as a backup roller brush 13, a body extension, etc., for use with the cleaning system. The user can place the familiar cleaning accessories in the accommodating part 24 according to the actual use requirement, thereby being convenient for the user to use and improving the cleaning efficiency of the user.

Referring to fig. 3, the stopper portion 211 is configured to receive at least a portion of the roller 14. Referring to fig. 4, the stopper portion 211 is formed by a groove and/or a protrusion structure provided on the base 21 of the base station 2 to be fitted with each other. The limiting part 211 can limit the movement of the roller 14 in the horizontal direction, and the protruding structure in the limiting part 211 supports the handheld cleaning device 1 to a certain extent. Thus, the stability and safety between the handheld cleaning device 1 and the base 21 are improved.

Referring to fig. 5, in a state where the hand-held cleaning device 1 is placed on the base 21 of the base station 2, the wash tank 22 accommodates at least a part of the roll brush 13 therein, and the roll brush 13 in a wet state has a certain gap between a surface thereof facing the UV light module 23 and the UV light module 23. In this way, the UV light assembly 23 located in the cleaning tank 22 can make the light emitted therefrom, i.e., UV light, irradiate onto at least a part of the surface of the roller brush 13 through the gap, so as to sterilize and clean the roller brush 13.

In one embodiment of the present disclosure, the cleaning tank 22 is configured to have a shape matching with a part of the surface of the roller brush 13, for example, the cleaning tank 22 has a circular arc-shaped groove structure.

In one embodiment of the present disclosure, the brush bristles of the roll brush 13 are different in a dry state and a wet state. Specifically, after the rolling brush 13 performs the cleaning operation or is wetted by water, the bristles of the rolling brush will be slightly contracted, which can also be understood as the bristles will be attached to the rolling brush body. In one embodiment of the present disclosure, the diameter of the roller brush 13 in the dry state may be, for example, 60mm (millimeters), and then the diameter thereof in the wet state is > 50mm (millimeters).

By reasonably setting the supporting relationship between the hand-held cleaning device and the base station, the surface of the rolling brush can be selectively in line contact with the bottom wall of the cleaning tank 22 when the rolling brush 13 is in a dry state. Such an arrangement makes it possible for the hand-held cleaning device 1 to create a sufficiently large underpressure at the location of the rinsing bath 22 when the roller brush 13 is self-cleaning, in order to suck away the sewage flowing into the rinsing bath 22 when the roller brush 13 is self-cleaning. In addition, it is possible to ensure that the roller brush has a small resistance against the inner wall of the wash bowl 22 when rotating.

When the roller brush 13 is wetted with water, the diameter of the roller brush 13 becomes small, which allows a slight gap, for example, a gap of 2.5 to 3mm, between the surface of the roller brush 13 and the bottom 221 of the cleaning tank 22. UV light emitted by the UV light assembly 23 can thus impinge on the surface of the roller brush 13 over as wide a range as possible through this gap. This is because the UV light emitted from the light source of the UV light assembly 23 is emitted outward at an angle, the farther the surface of the roller brush 13 is from the UV light assembly 23, the larger the surface of the roller brush 13 is illuminated, and the greater the UV light range of the UV light emitted from the light source of the UV light assembly 23 is when the UV light passes through the gap and is illuminated onto the surface of the roller brush 13, so that it is ensured that as much surface of the roller brush 13 as possible is illuminated by the UV light. In one embodiment of the present disclosure, by properly arranging the positional relationship between the UV light assembly 23 and the roller brush 13, it can be ensured that the surface in the extending direction (i.e., the axial direction) of the roller brush 13 can be irradiated with UV light. Thereby, when the roll brush 13 is rotating, it is ensured that all surfaces of the roll brush 13 in the circumferential direction and the axial direction can be irradiated with the UV light.

In other embodiments of the present disclosure, when the roller brush 13 is in the dry state, there may be a gap between the surface of the roller brush and the bottom wall of the cleaning tank 22, that is, there is a gap between the surface of the roller brush and any position of the cleaning tank 22, which is not described in detail herein.

In actual use, the user may activate the self-cleaning function after placing the hand-held cleaning device 1 on the base 21 of the base station 2. During the self-cleaning process, the roller brush 13 performs a spinning motion under the control of the motor, and the UV light assembly 23 emits UV light for sterilization after operation. The light can be irradiated onto a part of the surface of the drum brush 13 through the cleaning bath 22. As the roller brush 13 is continuously rotated, the light emitted from the UV light assembly 23 can be irradiated to the entire surface of the roller brush 13. The roller brush 13 is sterilized and cleaned, bacterial communities attached to the surface of the roller brush 13 are reduced, the bacteria are prevented from breeding and emitting peculiar smell, and the service life of the roller brush 13 can be prolonged.

Referring to fig. 4, the extending direction of cleaning tank 22 is defined as the X-axis direction, and cleaning tank 22 is divided into a front tank wall 222 and a rear tank wall 223 by a tank bottom 221 extending along the X-axis direction of cleaning tank 22.

Specifically, referring to fig. 8, the UV light assembly 23 is disposed on the rear tank wall 223 of the cleaning tank 22 in the X-axis direction. Since the surface of the roller brush 13 in the dry state is in line contact with only the bottom 221 of the cleaning tank 22, there is a gap between the roller brush 13 and the rest of the cleaning tank 22 and between the UV light modules.

In order to allow the light emitted by the UV light assembly 23 to impinge on the surface of the roller brush 13. A through hole is required to be opened in the cleaning bath 22 at a position corresponding to the UV light module 23. The through-hole is configured to allow light emitted from the UV light assembly 23 to pass therethrough and irradiate onto a portion of the surface of the roll brush 13.

Referring to fig. 5 and 6, the UV light assembly 23 includes a lamp housing 234, a cover plate 233, a lamp plate 232, and a UV lamp 231 disposed on the lamp plate 232. In actual use, the lamp housing 234, the cover plate 233 and the underside of the cleaning tank 22 cooperate to form a sealed chamber. The lamp plate 232 sets up inside this cavity, can make the operational environment of lamp plate 232 be in sealed state all the time to the service life of extension UV optical assembly 23. Specifically, the cover plate 233 is fixedly coupled to the outer wall below the wash bowl 22. Lamp plate 232 is located the top of apron 233, and closes through apron 233 and make lamp plate 232 also can be in the same place with washing tank 22 fixed connection. Above the lamp plate 232, a lamp cover 234 is disposed, and the lamp cover 234 is configured to allow light emitted from the UV lamp 231 to penetrate therethrough.

The lampshade 234 is disposed at a through hole of the cleaning tank 22 and is sealed and fixed with the through hole. Referring to fig. 6, the UV light assembly 23 is an elongated structure extending in the X-axis direction. The lamp housing 234 is hermetically fixed to the through hole of the cleaning tank 22 by ultrasonic welding. Through sealed, the through-hole of seting up on the washing tank 22 can be shutoff to lamp shade 234 to the inside moisture of washing tank 22 can not contact with UV lamp 231, lamp plate 232 along the through-hole. Thus, the UV light module 23 is protected, and the service life thereof is prolonged.

Further, a UV light unit 23 is fixedly provided with the cleaning bath 22. Can ensure that the light angle and the irradiation range that UV lamp 231 sent remain in stable within range, and then sterilization efficiency and the sterilization effect when cleaning system carries out the automatically cleaning also can be in a relatively stable state, can not change cleaning effect because of vibrations or colliding with.

In another embodiment of the present disclosure, the lampshade 234 and the cleaning tank 22 can be fixed and sealed together by a sealant.

In another embodiment of the present disclosure, the outer end surface of the lampshade 234 is flush with the inner wall of the cleaning tank 22 in the region of the lampshade 234 corresponding to the through hole, i.e., the lampshade 234 can completely fill the through hole formed on the cleaning tank 22, so that the inner wall of the cleaning tank 22 is kept relatively smooth. Thus, after the lamp housing 234 and the cleaning tank 22 are sealed and fixed, when the cleaning system performs the self-cleaning function, moisture is not accumulated in the cleaning tank 22, and the sterilization and cleaning effect of the UV light assembly 23 is not affected by the accumulated water on the outer wall of the lamp housing 234 to affect the light penetration irradiation.

In another embodiment of the present disclosure, referring to fig. 6, the number and the position of the lamp housings 234 correspond to the number and the position of the UV lamps 231 provided on the lamp panel 232 in the UV light assembly 23. And, a through hole for matching with the lamp shade 234 is opened on the corresponding cleaning tank 22. In this manner, light emitted from the UV lamp 231 can pass through the lamp housing 234 and the through hole and irradiate at least a portion of the surface of the roll brush 13. In the UV light assembly 23 of this disclosure, a lamp plate 232 can be shared to a plurality of UV lamps 231, and this lamp plate 232 passes through apron 233 package in the below of washing tank 22, and each UV lamp 231 corresponds and is equipped with a lamp shade 234, and a through-hole has been seted up in each lamp shade 234 department to washing tank 22, and two at least lamp shades 234 lock respectively are on corresponding UV lamp 231, and with the corresponding through-hole cooperation that washing tank 22 was seted up together. In other embodiments of the present disclosure, the lampshade 234 of the present disclosure may also have an elongated shape, and the extending direction of the elongated shape is the same as the extending direction of the lamp panel 232, so that all the UV lamps 231 are fastened together by one lampshade 234. Accordingly, the cleaning tank 22 is provided with a through hole in a long strip shape, which will not be described in detail herein. It is because the UV light irradiates more surface of the rolling brush 13 through the gap, so that the lamp housing 234 can be spaced in the cleaning tank 22, which can save the number of the lamp housing 234 and the UV lamp 231, and can ensure more irradiation area of the rolling brush. In one embodiment of the present disclosure, the light emitted from the UV lamp 231 is configured to irradiate the entire surface of the drum brush 13 corresponding to the UV lamp 231 and extending in the X-axis direction. That is, the UV light does not irradiate the entire circumferential surface of the roll brush 13, which is required to be realized by controlling the rotation of the roll brush 13, but may irradiate the entire surface of the roll brush 13 corresponding to the UV lamp 231 and extending in the X-axis direction.

It is noted that when the sterilization cleaning is performed by using UV light, the energy of the UV light emitted by the UV light is large, and the energy is large to be beneficial for killing bacteria. But this light can cause discomfort to the user if it impinges directly on the user's skin or enters the user's eyes. Therefore, it is necessary to change the position or the light emitting angle of the UV light assembly 23 so that the light emitted from the UV light assembly 23 can be irradiated only to the inside of the cleaning system and not to the outside.

Referring to fig. 8, in a preferred embodiment of the present disclosure, the UV light assembly 23 is disposed on the rear tank wall 223 of the cleaning tank 22. At this time, the light emitted from the UV light assembly 23 is configured to be shielded by the floor brush housing 12 and the roll brush 13 so that the light does not irradiate other areas. Therefore, the user can be prevented from being aware of or being irradiated by the light emitted by the UV light assembly 23, and the use safety of the product is improved.

With continued reference to fig. 6, the length of the UV light assembly 23 in the X-axis direction is close to the length of the roller brush 13. Specifically, the length of the lamp panel 232 depends on the angle of the light emitted from the UV lamp 231, so that the surface of the roll brush 13 in the X-axis direction can be covered at an optimal angle. According to the luminous angle of UV lamp 231, reasonable edge X axle direction interval sets up a plurality of UV lamps 231 on lamp plate 232, just can realize letting the light that UV lamp 231 sent realize the total coverage with the ascending surface in round brush 13X axle direction, and then after round brush 13 carried out the spin motion, this light can shine the whole surfaces of round brush 13 to it is clean to realize disinfecting to round brush 13.

Referring to fig. 11, the UV lamp 231 emits light at a certain angle, and the light emitted therefrom is always irradiated outward at a predetermined angle. That is, the regions within the included angle of the light rays may be illuminated by the light rays emitted by the UV light assembly. Further, in order to cover more surfaces of the roll brush 13 with the light emitted from the UV light assembly 23, the light emitting angle of the UV lamp 231 may be adjusted.

With continued reference to fig. 11, between two adjacent UV lamps 231, there is a crossover point between the emitted light rays. Also in order to enable the UV lamp 231 to irradiate more surfaces of the drum brush 13, the full-coverage irradiation sterilization cleaning is realized. The intersection of the emitted light rays of two adjacent UV lamps 231 is located outside the corresponding surface of the roll brush 13. Referring to the view direction of fig. 11, the UV lamps 231 are located below the roller brush 13, and the intersection point of the light rays emitted from two adjacent UV lamps 231 is located outside the lower surface of the roller brush 13, i.e., at a position below the lower surface of the roller brush 13, so that it is ensured that the lower surface of the roller brush 13 can be irradiated with the UV light rays.

Of course, the light emission angle intersection of two adjacent UV lamps 231 may also be disposed just next to the surface of the roll brush 13.

In one embodiment of the present disclosure, the light emitting angle of the UV lamp 231 is 130 °. Through a plurality of experimental tests, when the light emitting angle of the UV light is set at 130 °, the light coverage of the UV lamp 231 is maximized, and the sterilization and cleaning effects are optimized. Further, set up UV lamp 231 interval distribution back on lamp plate 232, when the clean scope of sterilization and the effect of assurance, can adopt UV lamp 231 of less quantity to realize that the sterilization is clean. The manufacturing cost of the UV light assembly 23 can also be reduced relative to other angles.

FIG. 8 illustrates an embodiment in which the UV light assembly 23 is disposed on the tank wall 223 after the rinse tank 22. In this embodiment, the light emission angle of the UV lamp 231 is configured to: the light irradiated from the UV lamp 231 outside the surface of the drum brush 13 is configured to be shielded by the floor brush housing 12 or by the cleaning tank 22. In the embodiment shown in fig. 8, in order to ensure that the UV lamp 231 can irradiate as much of the surface of the roll brush 13 as possible, the UV lamp 231 having a large light emission angle may be selected, for example, having a light emission angle of 130 °. Most of the light is irradiated on the surface of the drum brush 13 facing the rear groove wall 223, and the light toward the rear side (the right direction in fig. 8) of the drum brush 13 is blocked by the rear groove wall 223 or by the floor brush housing 12, and the light of the side is not emitted to the outside and is observed by the user. Light toward the front side (left direction in fig. 8) of the roll brush 13 may be blocked by the roll brush 13, and specifically, the roll brush surface has a point, a straight line between the point and the point where the UV lamp 231 is located is a tangent line of the point, and light toward the front side of the roll brush 13 may not exceed the tangent line; alternatively, the light toward the front side of drum brush 13 (left direction in fig. 8) may be blocked by front groove wall 222, so that the light on that side is not emitted outward from the gap between drum brush 13 and washing tub 22, and thus may be prevented from being observed by the user.

In this embodiment, since the gap between the front side of the rolling brush 13 and the cleaning tank 22 is communicated with the outside after the rolling brush 13 is matched with the cleaning tank 22, the position of the UV lamp 231 on the rear tank wall 223 and the light emitting angle need to be properly set to prevent the light from being radiated from the gap. In one embodiment of the present disclosure, the UV lamp 231 may be irradiated on the drum brush 13 obliquely upward, so that it may be irradiated on the tank bottom 221 or the front tank wall 222 of the cleaning tank 22 even if a part of light is beyond the edge of the drum brush 13.

Referring to FIG. 9, in another embodiment of the present disclosure, UV light assembly 23 is disposed on front tub wall 222 of cleaning tub 22 in the X-axis direction. Otherwise, the present embodiment is the same as the above embodiment, and is different from the above embodiments in that the UV light assembly 23 is disposed at a different position, and the emission angle range of the UV lamp 231 is also required to be adjusted accordingly. It should be noted that, in practical use, the specific position and the light emitting angle of the UV light assembly 23 need to be adjusted according to the structure of the floor brush assembly 11 and the cleaning tank 22, so that the light emitted from the UV lamp 231 can be blocked by the rolling brush 13, the floor brush housing 12, and the base station 2.

In another embodiment of the present disclosure, the UV light assembly 23 may also be disposed at the position of the groove bottom 211 of the cleaning groove 22 along the X-axis direction, referring to fig. 7. In this embodiment, the roller brush 13 is in line contact with the surface of the lamp housing 234 in the dry state. When the UV lamp 231 irradiates vertically upward, a part of UV light may be irradiated on the surface of the roll brush 13 from the gap between the roll brush 13 and the cleaning tank 22. When the rolling brush 13 is in a wet state, a gap is formed between the rolling brush 13 and the entire lamp housing 234, thereby ensuring that UV rays can be irradiated onto as much surface of the rolling brush 13 as possible. In addition, when the UV lamp 231 irradiates vertically upwards, the light on the right side of the view is blocked by the rear slot wall 223 or by the floor brush housing 12, and the light on the left side of the view is blocked by the front slot wall 222. Of course, the light emitted may be selected so as not to exceed the outer contour of the roller brush 13.

Specifically, the front side surface of the rolling brush away from the floor brush has a first point, a straight line between the first point and the point where the UV lamp 231 is located is a tangent line of the first point, and a light ray (left direction in fig. 7) toward the front side of the rolling brush 13 does not exceed the tangent line of the first point; the rear side surface of the roll brush adjacent to the floor brush has a second point, and a straight line between the second point and a point where the UV lamp 231 is located is a tangent line of the second point, and a light ray (right direction in fig. 7) toward the rear side of the roll brush 13 does not exceed the tangent line of the second point. Of course, the number of UV light assemblies 23 is not limited to only one set, depending on the actual use requirements. Two or more sets of UV light assemblies 23 may also be provided. The arrangement direction of the UV light assembly 23 is not limited to the arrangement along the X-axis direction, as long as the sterilization and cleaning function can be performed when the cleaning system performs self-cleaning.

In one embodiment of the present disclosure, the UV lamps 231 are provided in at least two rows, wherein at least one row of UV lamps 231 is arranged at intervals in the rear tank wall 223 of the cleaning tank 22 along the X-axis direction; at least one row of UV lamps 231 is arranged at intervals along the X-axis direction in the front tank wall 222 of the cleaning tank 22. That is, at least one row of UV light assemblies 23 is disposed on each of the front and

rear tank walls

222 and 223 of the cleaning tank 22, thereby irradiating more surfaces of the roll brush 13. Therefore, the sterilization and cleaning efficiency can be improved, and the sterilization and cleaning time can be shortened.

In this embodiment, the position of the UV lamp 231 located on the front bath wall 222 in the cleaning bath 22 may be higher than the position of the UV lamp 231 located on the rear bath wall 223 in the cleaning bath 22. For example, UV lamp 231 on rear tank wall 223 may be positioned on rear tank wall 223 near the bottom 221 of tank, while UV lamp 231 on front tank wall 222 may be positioned on front tank wall 222 near the opening of cleaning tank 22. This is because the light from the UV lamp 231 on the rear groove wall 223 can be blocked by the front groove wall 222 and does not irradiate to the outside from the gap between the roll brush 13 and the front wall 222. And if the UV lamp 231 located on the front groove wall 222 is disposed too close to the groove bottom 221, light emitted therefrom may be irradiated to the outside from the gap between the roll brush 13 and the front side wall 222 to be sensed by the user.

In another embodiment of the present disclosure, the UV lamps 231 located on the front groove wall 222 are disposed opposite to or offset from the UV lamps 231 located on the rear groove wall 223 by a predetermined distance.

Or, the lamp on the front wall of the groove, the lamp on the rear wall of the groove, the lamp on the front wall of the groove and the lamp on the rear wall of the groove are connected into a straight line, and the straight line and the X-axis straight line form a certain angle. Thus, the irradiation range of the UV lamp 231 can be more comprehensive, and the sterilization effect thereof is more balanced.

Referring to fig. 10, two sets of UV light assemblies 23 are disposed on the cleaning tank 22 along the X-axis direction, and the UV light assemblies 23 are arranged in a manner of gradually departing from the cleaning tank 22 from both ends of the cleaning tank 22 to the center of the cleaning tank 22. Referring to the view direction of fig. 10, in which the left side of the UV light assembly 23 is closer to the cleaning tank 22 at the left end, and the right end corresponds to the center of the cleaning tank 22 and is farther from the cleaning tank 22, it can be understood that the UV light assembly 23 is disposed obliquely, so that the UV light on the UV light assembly 23 is gradually away from the cleaning tank 22 in the direction from the end of the cleaning tank 22 to the center of the cleaning tank 22. The arrangement of the UV light assembly 23 on the right is the same and will not be described in detail here.

In this way, when it is ensured that the light emitted by the UV lamps 231 can cover at least part of the surface of the roll brush 13 in the X-axis direction, the number of UV lamps 231 arranged on the lamp panel 232 is reduced compared to the number of UV lamps 231 used in one set of UV light assemblies 23. This is because the farther the UV lamp 231 is from the cleaning tank 22, the larger the irradiation area of the UV lamp 231 is, and thus the manufacturing cost of the apparatus can be reduced while ensuring the sterilization and cleaning of the UV light module 23.

In an embodiment of the present disclosure, referring to fig. 4, a UV light assembly 23 may also be disposed on an inner wall of the accommodating portion 24, and when the cleaning accessory is placed in the accommodating portion 24, light emitted from the UV light assembly 23 located inside the accommodating portion 24 can be irradiated onto the cleaning accessory, so as to sterilize and clean the cleaning accessory.

The structure of the UV light assembly 23 is the same as the previous embodiments, and will not be described herein. The UV light assembly 23 disposed inside the receiving portion 24 may be configured to be disposed around an inner wall of the receiving portion 24. The light emitted from the UV lamp 231 can surround and cover the cleaning attachment placed inside the accommodating portion 24, and can perform 360 ° all-round sterilization and cleaning.

Specifically, the UV light assembly 23 disposed on the inner wall of the accommodating portion 24 is gradually disposed axially upward from the bottom of the inner wall of the accommodating portion 24 to the opening of the inner wall of the accommodating portion 24, that is, at least one UV lamp is disposed at different heights. In this way, the light emitted by the UV light assembly 23 can sterilize and clean all the equipment placed in the receptacle 24.

In another embodiment of the present disclosure, the UV light assemblies 23 are configured to be vertically disposed on the inner wall of the accommodating portion 24, and the UV light assemblies 23 may also be disposed in a plurality of, for example, three, distributed on the circumferential side wall of the accommodating portion 24, so that the accessories in the accommodating portion 24 can be fully irradiated. The UV light assembly 23 is disposed in such a way that the cleaning accessory placed in the accommodating portion 24 can be sterilized and cleaned, and those skilled in the art can select and design the cleaning accessory according to actual use requirements without any limitation.

Referring to fig. 3, the base 21 of the base station 2 is further provided with a charging assembly 25, the charging assembly 25 is, for example, a charging male head arranged on the base 21, and a charging female head arranged on the machine body 16; or the charging male head is arranged on the machine body 16, and the charging female head is arranged on the base 21.

Under the condition that hand-held type cleaning device 1 placed on base 21, the male head that charges can be connected with the female head cooperation that charges, charges fuselage subassembly 15. Further, the charging assembly 25 can also restrict the placement position of the hand-held cleaning device 1 and the base station 2.

Fig. 2 illustrates an embodiment in which the charging assembly 25 is a charging male, which in one embodiment of the present disclosure is configured to extend vertically upward or obliquely upward. Hand-held type cleaning device 1 is through from the top down mode place base 21 on, and the mode cooperation of pegging graft is in the same place from top to bottom to the public head that charges and the female head that charges, charges. Further, only after the machine body 16 is lifted up, the charging male head and the charging female head can be separated from each other, and charging is finished. In this way, the stability of the hand-held cleaning device 1 after placement can be improved.

In this embodiment, the specific positions of the handheld cleaning device 1 and the base station 2 after being placed together are limited by the position relationship between the cleaning tank 22, the rolling brush 13, the limiting portion 211, the roller 14, the body assembly 15 and the charging assembly 25 located on the base 21, and the stability between the handheld cleaning device 1 and the base station 2 is ensured.

In addition to the cleaning system described above, the present disclosure also provides a base station 2 for placing the hand-held cleaning device 1. The specific structure of the handheld cleaning device 1 and the base station 2 has been described in detail in the foregoing, and is not described herein in detail.

Further, the present disclosure also provides a control method for controlling the above cleaning system. The specific steps and effects of the control method of the cleaning system of the present disclosure will be described in detail below with reference to one embodiment.

In the case where the hand-held cleaning device 1 is placed on the base station 2 from the top down, the drum brush 13 in the floor brush assembly 11 is at least partially located in the wash bowl 22 of the base station 2. And since the brush states of the roller brush 13 in the dry and wet states are different, the roller brush 13 may be configured such that the surface is disposed in line contact with the groove bottom 221 of the cleaning groove 22, mainly the state of the roller brush 13 in the dry state. Thereby ensuring that the negative pressure formed between the hand-held cleaning device 1 and the cleaning tank 22 is sufficiently large so that the main motor can suck the liquid at the cleaning tank 22 away.

The roller 14 of the floor brush assembly 11 is at least partially located in the stopper 211 of the base 21 of the base station 2. The charging assembly 25 on the body 16 is connected with the charging assembly 25 on the base 21 of the base station 2.

At this point, the hand-held cleaning device 1 can be started for self-cleaning operation. During the self-cleaning operation, the water pump in hand-held cleaning apparatus 1 controls the water tank to supply liquid to the area where roller brush 13 is located, so that roller brush 13 can be cleaned in cleaning bath 22. The rolling brush 13 is in a wet state after receiving water, or the rolling brush 13 is in a wet state after working, and a certain gap is formed between the washing tank 22 and the rolling brush 13 in the wet state, so that the rolling brush 13 can smoothly rotate, and friction between the rolling brush and the inner wall of the washing tank 22 is avoided. In addition, at least part of the rolling brush 13 is positioned in the cleaning tank 22, so that the sewage left by the rolling brush 13 in the self-cleaning rotating process can enter the cleaning tank 22, and the sewage is prevented from being thrown out when the rolling brush 13 rotates.

After the water tank stops supplying water to the rolling brush 13, the cleaning device 1 controls the UV light assembly 23 to start operation, and light emitted by the UV light assembly 23 can pass through the through hole formed in the cleaning tank 22 and irradiate at least part of the surface of the rolling brush 13. The surface of the roller brush 13 is irradiated by the UV light assembly 23, so that the surface of the roller brush 13 is sterilized and cleaned. Thereby effectively eliminating the bacterial community attached to the rolling brush 13, prolonging the service life of the cleaning system and meeting the use requirements of users.

The time that the UV light assembly 23 is turned on may be any time the water tank stops supplying water to the drum brush 13. For example, in one embodiment of the present disclosure, the UV light assembly 23 may be controlled to be turned on after the water pump is stopped, or the UV light assembly 23 may be turned on after the main motor sucks the sewage in the cleaning tank 22, or the UV light assembly 23 may be controlled to be turned on in the final rolling brush spin-drying stage of the self-cleaning, in the rolling brush spin-drying stage of the self-cleaning, the water pump is stopped, the main motor and the rolling brush motor operate, the rolling brush motor drives the rolling brush to rotate, the main motor operates to generate a suction force, and the UV light assembly 23 sterilizes and sterilizes the rotating rolling brush.

As shown in table 1, table 1 is an example of a complete self-cleaning process, the UV light assembly 23 may be turned on in stages B1, B2, B3, and B4 as shown below; alternatively, the UV light assembly 23 is turned on at stages B3, B4; alternatively, the UV light assembly is turned on only during the final B4 drying stage.

TABLE 1 self-cleaning flow sheet

The following describes the technical solution adopted in the present disclosure with reference to specific application scenarios to assist understanding. The cleaning device 1 is not limited to a hand-held cleaning device, but may also be a self-propelled cleaning device. In the following application scenario, the cleaning device 1 is described as a hand-held floor washing machine.

Application scenario 1

In the cleaning system, a hand-held scrubber (as hereinafter "scrubber") includes a body assembly 15, a floor brush assembly 11 rotatably coupled to the body assembly 15, and a base station 2 for positioning the scrubber. When the user does not need to use the scrubber, the scrubber can be placed onto the base station 2 from above downwards. The scrubber machine cooperates with the base 21 of the base station 2 to enable stable placement of the scrubber machine. Avoiding the occurrence of unnecessary damage caused by the toppling or rotation of the floor washing machine.

Specifically, after the user places the scrubber machine from top to bottom to the base station 2, the roller brush 13 in the floor brush assembly 11 cooperates with the cleaning tank 22 arranged on the base 21 of the base station 2, the roller 14 cooperates with the limiting part 211, and the charging assembly 25 on the machine body 16 cooperates with the charging assembly 25 on the base 21. Through many-sided spacing cooperation, the guarantee floor scrubber can be placed steadily.

With the scrubber in place on the base 21, the user may choose to turn on the self-cleaning function manually or the cleaning system automatically. A water pump located in the body assembly 15 can now control the water tank to supply liquid to the area of the roller brush 13. The drum brush 13 is rotatable under the control of a motor and performs water cleaning in cooperation with the washing tub 22 by the water supplied from the water tank. Meanwhile, the sewage left in the rotation process of the rolling brush 13 can directly enter the cleaning tank 22, so that the sewage is prevented from being thrown out when the rolling brush 13 rotates. The main motor inside the cleaning system sucks the sewage in the cleaning tank 22 into the sewage tank by the negative pressure formed between the handheld cleaning apparatus 1 and the cleaning tank 22. By repeating the above steps, water cleaning of the roll brush 13 is realized.

After the water tank stops supplying water, the rolling brush 13 continues to keep rotating, and the main motor continues to keep a suction state to air-dry the rolling brush 13. At this time, the UV light assembly 23 operates to emit UV light and irradiate onto a portion of the surface of the roll brush 13 to sterilize and clean the roll brush 13. Since there is a certain gap between the surface of the roll brush 13 and the lamp housing 234 when in a wet state, UV rays can be irradiated onto more surfaces of the roll brush 13 through the gap. As the roll brush 13 rotates, the UV rays may be repeatedly irradiated to the surface of the roll brush 13. After the preset time, the self-cleaning function is finished.

At this time, the rolling brush 13 can be effectively and completely cleaned by water cleaning and sterilization cleaning. The cleaned rolling brush 13 has better cleaning capability, and meanwhile, the bacterial colonies attached to the rolling brush 13 are greatly eliminated, so that peculiar smell and mildew can be avoided. Finally, the service life of the rolling brush 13 can be prolonged, and the use experience of a user is improved.

Application scenario 2

In this application scenario, the rest is the same as the above embodiment, except that after the user manually starts or the cleaning system automatically starts self-cleaning, in the process of self-cleaning, the start-up operation time of the UV light assembly 23 is the time when the water pump does not work. That is, as long as the water pump does not control the water tank to supply water to the area where the rolling brush 13 is located, the UV light assembly 23 is turned on to irradiate the surface of the rolling brush 13, and the sterilization and cleaning function is performed. Therefore, the self-cleaning time of the cleaning system can be greatly shortened, and the use experience of a user is effectively improved.

The foregoing description of the embodiments of the present disclosure has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen in order to best explain the principles of the embodiments, the practical application, or improvements made to the technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
