Description

A double-roller sweeping device

technical field

The present invention relates to the technical field of environmental cleaning equipment.

Background technique

Whether it is in home life or work, it is often necessary to clean the environment, and sweeping is the most frequent. Existing general cleaning equipment includes a combination of brooms and dustpans, or a horizontal circular rotating brush for sweeping (such as a sweeping robot), etc. The bottom end of the garbage inlet of the existing cleaning equipment needs to be close to the ground in order to effectively sweep the garbage into the ground. In the garbage box, the shovel blade needs to be attached to the ground, but the existence of the shovel blade has many problems or deficiencies, such as the lower end of the shovel blade is easy to carry, presses the dirt, etc.; the tip of the shovel blade must have a thickness to connect with the ground There will be a height difference between them, and there will be residual garbage in the gaps, so it is impossible to clean all the small particles of garbage into the garbage box; generally, there will be gaps between the floor tiles in the structure of laying bricks on the ground. Floor seams, etc., also cause problems such as garbage residue. For example, when the hand-push integrated cleaning equipment suddenly gets stuck in the brick seam, the stuck feeling causes a very poor user experience, and at the same time, it is easy to skip a small part of the ground and the cleaning is not in place; generally The volume of garbage that can be cleaned by the integrated cleaning equipment is relatively small; hair, etc. are easily mixed between the brushes, which affects the use of sweeping. The coverage of the ground may be incomplete and omissions may occur; traditional cleaning equipment is not easy to pick up and collect the dirty water on the ground. If it gets wet, it is inconvenient to continue sweeping, and it is easy to form sludge residues, etc. Generally, sweeping equipment may need to use a vacuum cleaner to help. The pressure module picks up garbage, which is noisy, consumes a lot of energy, and has a poor picking effect.

To further optimize the technical solution, the cleaning roller of a double-roller sweeping device is spirally transported to the middle, and the cleaning fins are spiraled from both sides to the middle.

The beneficial effects of the present invention are:

1. The cleaning roller rotates along the horizontal axis. When cleaning the garbage, it adopts the form of scraping the ground. The action is to press down and then carry it on the ground for final pick-up. It can clean relatively large volume of garbage, and the garbage is not easy to be knocked off, and the cleaning is better and clean. ;The use of the two cleaning rollers can remove the existence of the blade in the traditional cleaning tool, that is to say, the negative influence of the blade is eliminated, there is no feeling of jamming, and there is no garbage residue formed by the height difference with the ground. It also avoids the problem that the bottom end of the shovel is pressing the garbage, but the effect of picking up garbage is better, and at the same time, it can better pick up the water and garbage on the ground. It has a part of the mopping function, which can realize wet sweeping, and the function of scraping and collecting water further improves the cleaning experience, and can clean some areas with water without affecting the continued sweeping, and the garbage bin can hold the garbage and water swept up;

The cleaning roller has a structure with cleaning fins, which is conducive to the self-cleaning of the contact part between the cleaning fins and the ground, and is conducive to cleaning large-volume garbage, and has high adaptability to cleaning garbage. Less omissions, cleaner cleaning, and better adaptability to sweeping in both front and rear directions. The setting of cleaning fins is conducive to balancing the contradiction between continuous and effective scraping and resistance wear, and is conducive to balancing the self-cleaning effect and self-cleaning effect of cleaning fins. The contradiction of cleaning resistance is conducive to balancing the contradiction between effective scraping and the size of the garbage that can be entered, and is conducive to balancing the contradiction between effective scraping and continuous scraping, and is conducive to reducing the time and distance of garbage and dirty water dragging on the ground;

2. When two cleaning rollers are used together, they are installed on the same side and rotate in the opposite direction. When the diameters of the two cleaning rollers are different, the formed parabolic angle is conducive to the collection of garbage and water.

3. The setting of the primary filter can improve the experience of cleaning a small amount of water. When the ground is wet or sprinkled with less water, the garbage and water can be swept into the garbage bin through the cleaning component, and the dirty water can enter the lower side of the primary filter. When the water outlet space is slightly shaken, it can reduce the amount of water shaking in the water storage space and reduce overflow. At the same time, a pump is installed to facilitate the collection of dirty water, which is beneficial to reduce the required water storage space in the garbage bin and improve the cleaning and water collection efficiency. Experience, and set up a sewage tank at the same time to make water collection more convenient.

4. The scraping device can effectively improve the separation efficiency of the cleaning fins and the carried garbage and dirty water, reduce or even prevent the garbage and dirty water from continuing to rotate with the cleaning roller, and reduce the residue caused by falling on the ground.

5. When the garbage bin is integrated with the casing and the sealing door is set together, it is easy to open and has good structural integrity.

6. When the garbage bin is a drawer structure, it is more convenient to receive garbage and sewage, and to extract and dump garbage and sewage;

7. The cleaning roller is helical. When it is in contact with the lower scraper, the distal end of each cleaning fin is in point contact with the end of the lower scraper at the initial contact, and it is continuous, which plays the role of buffering contact and reduces impact noise. , Compared with the cleaning fin in the axial direction (the initial contact between the distal end of the cleaning fin and the end of the lower scraper is line contact, and the impact is greater), the spiral shape is conducive to reducing the gap between the cleaning fin and the lower scraper The knocking noise and the vibration noise when the cleaning fins are separated from the lower scraper;

In the working state, the effective scraping distance formed by the cleaning fins 2 of at least one cleaning roller 1 on the working surface is continuous. The cleaning assembly is installed at the front of the casing 4. The diameter of the cleaning roller 1 on the front side is larger than the diameter of the cleaning roller 1 on the rear side. The cleaning roller 1 on the front side is a large cleaning roller 1a, and the cleaning roller 1 on the rear side is a small cleaning roller. 1b. The cleaning assembly is equipped with a scraping device; the scraping device includes a lower scraper 24 for scraping the dirt on the small cleaning roller 1b, the scraping end of the lower scraper 24 cleans the small cleaning roller 1b, and the garbage bin 3 The inlet is in contact with the dirt-shedding end of the lower scraper 24 . A primary filter screen 6 is installed at the bottom of the garbage bin 3 ; the space between the primary filter screen 6 and the inner bottom end of the garbage bin 3 is a water storage space 7 . It also includes a water collecting device; the water collecting device includes a suction pump 17 and a sewage tank 35 ; the suction pump 17 extracts the water in the water storage space 7 ; The garbage bin 3 and the casing 4 are integrally constructed, and a sealing door 26 is fitted at the sewage discharge end of the garbage bin 3 . The sealing door 26 is hermetically connected to the sewage discharge end of the garbage bin 3 through magnetic attraction. The garbage bin 3 is a drawer 29 , and the drawer 29 is slidably connected with the cabinet 4 . The end of the garbage bin 3 close to the small cleaning roller 1b is provided with an anti-drip plate 5, and the lower end of the anti-drip plate 5 is received and matched with the small cleaning roller 1b. The cleaning roller 1 is in a spiral shape that is transported to the middle, and the cleaning fins 2 are spiraled from both sides to the middle.

When the present invention is used, it can be selected according to actual use requirements, and can be used in various combinations, and is not limited to the order or combination of the embodiments described in this specification. The casing 4 can be set to a suitable shape according to the actual use, which can be realized by those skilled in the art. The driving motor 9, the water pump 17, the ultraviolet lamp 21, etc., the required electric energy can be supplied by the battery connection. The description of the counterclockwise or clockwise direction used is based on the view from the left side of the casing 4, and the orientation of the transmission cavity 15 is the left side (the transmission cavity 15 is not limited to the left side, it is only used for example description). The descriptions in directions such as front, back, left, and right, and the embodiments are all for the convenience of description and understanding, and should not limit the protection scope of the present invention.

1, the main principle is explained, taking the cleaning roller 1 with cleaning fins 2 as an example (the large cleaning roller 1a is located in front of the small cleaning roller 1b in the figure), two cleaning rollers 1 are installed side by side in front of the casing 4 The surface that needs to be cleaned, such as the side and the ground, is the working surface. The dirt inlet end of the cleaning assembly is the side where the two cleaning rollers 1 enter the garbage, which is generally the side that contacts the ground. That is to say, the side where the two cleaning rollers 1 are separated from each other, and the triangular-like area formed between the two cleaning rollers 1 and the working surface is the dirt inlet area 43 . It mainly realizes the sweeping function, and at the same time has a certain ability to mop the floor and collect water, which improves the cleaning experience. This property is specially emphasized here. The two cleaning rollers 1 rotate in opposite directions, and at the contact position in the middle, the direction of movement is upward, forming a pair of clips that move upward. When sweeping garbage, after touching the garbage on the ground, the cleaning fins 2 can bend or compress, scrape the floor for cleaning, and finally carry garbage, and move forward mainly by feeding garbage from the cleaning roller 1 on the front side, and the front side is the main garbage. At the entrance, since the bottom end of the casing 4 is at a certain height from the ground, the small garbage smaller than this height can pass through the bottom end of the casing 4, and then when moving to the rear side, the small garbage can enter from the cleaning roller 1 on the rear side. It also has the function of mopping and collecting water. When there is water on the ground, in the process of circular rotation, on the side that the mopping direction points to, when the cleaning fin 2 first touches the ground and forms an acute angle with the ground, it scrapes the ground. The effect is good, and problems such as jumping and jamming are not easy to occur at this time. Therefore, the cleaning roller 1 that rotates counterclockwise moves backward and has a good scraping effect, and the cleaning roller 1 that rotates clockwise has a good scraping effect when it moves forward. And there is an effective scraping distance between the single cleaning fin 2 when it touches the ground and when it rotates off the ground (cleaning fins 2 with different hardness, different shapes, different lengths or other types of cleaning rollers 1, the effective scraping distance is formed. Different, it can be measured through experiments and other methods to determine the density of cleaning fins 2 or angular interval, etc.), the effective scraping distance is the interval with better scraping effect (clean scraping), and the better scraping effect also needs to ensure continuous and effective. Scraping the ground, that is, the effective scraping distance of the cleaning fins 2 of the cleaning roller 1 has continuity (can overlap), ensuring the continuity of scraping the ground and avoiding the residual marks of unscraped or unscraped strip water marks.

Embodiment 1, Figure 2, includes a cleaning assembly, and the cleaning assembly is installed at the front of the casing 4, and the garbage bin 3 is located at the rear. The cleaning assembly includes two cleaning rollers 1, and the diameter of the front cleaning roller 1 is larger than that of the rear Cleaning roller 1 diameter, rely on two cleaning rollers 1 to pick up garbage and dirty water.

As shown in Figure 3, the power and transmission unit includes a transmission device, a drive motor 9, and a battery. The transmission device includes a main sprocket 11 connected to the output end of the drive motor 9, and a first sprocket 13 connected to the end of the large cleaning roller 1a. 2. The second sprocket 14 connected to the end of the small cleaning roller 1b, the main sprocket 11 is driven by the chain 12 with the first and second sprockets 13 and 14, and the large cleaning roller 1a and the small cleaning roller 1b rotate in opposite directions. A transmission cavity 15 can be provided on the left side of the casing 4, and is matched with the installation cavity cover 16. The transmission device is arranged in the transmission cavity 15, and the transmission cavity 15 cooperates with the installation cavity cover 16 (the transmission device can be an independent component, which is installed in the casing 4. superior). In addition to the chain 12 sprocket drive, the transmission device can also be double-sided pulley drive, pure gear drive, pulley belt drive combined with gear drive, chain 12 sprocket combined with gear drive, worm gear drive, etc. In this embodiment, the drive motor 9 can be installed in the power compartment 8, and the power compartment 8 can be located at the upper end of the rear of the garbage bin 3 (the position of the power compartment 8 is not limited to the upper end of the rear of the garbage bin 3, but can be arranged in the garbage bin 3 or the casing 4, such as the upper end of the front of the garbage bin 3 is close to the position of the cleaning assembly, or the lower end of the garbage bin 3). 4, the drive motor 9 can also be arranged on the left or right side of the casing 4. The output end of the drive motor 9 is directly connected to a single cleaning roller 1 for transmission, and relies on conventional power transmission equipment to drive another cleaning roller 1 in the same group in the reverse direction. Rotation; the drive motor 9 can also be installed on the left side of the inside of the casing 4, the drive motor 9 is sleeved and set at the axis of the cleaning roller 1, inside the cleaning roller 1, and the output end of the driving motor 9 is connected with the cleaning roller 1 , saving space in the left and right directions. When it is necessary to output power to the outside, such as driving another cleaning roller 1 to rotate, a dual-axis drive motor 9 can be installed. One end of the output end of the drive motor 9 is connected to the sleeved cleaning roller 1, and the other One end can be connected with a transmission device to drive the other cleaning roller 1 to rotate, and other embodiments are also applicable to this type of installation of the drive motor 9 . The power and transmission unit can also be realized without relying on electrical energy. For example, when the user pushes the casing 4, the rotation of the wheels 20 generates power, and then the transmission device drives the cleaning assembly to rotate, and the two cleaning rollers 1 rotate in the opposite direction.

The two cleaning rollers 1 are installed on the front of the casing 4, and they are installed one after the other. In the middle of the two, the cleaning fins 2 of the two are pressed against each other to form a staggered pressing area. The large cleaning roller 1a rotates counterclockwise and the small cleaning roller 1b rotates clockwise, both of which are powered by the power and the transmission unit to drive the rotation, relying on the chain 12 for simultaneous transmission, the first sprocket 13 in the chain 12 On the inner side, the second sprocket 14 is on the outer side, and meshes with the chain 12 for transmission respectively, so the two cleaning rollers 1 turn in opposite directions. In the process of pushing forward and pulling back, the functions of sweeping and mopping can be realized at the same time. The sweeping function is realized by the clamping of two cleaning rollers 1, and the mopping and water collecting function are mainly realized by the rear side clockwise when moving forward. The rotating cleaning roller 1 is realized. When it is backward, it is mainly realized by the cleaning roller 1 rotating counterclockwise on the front side. With the help of the wetting of water on the ground, the garbage attached to the ground is removed from the ground (here, it is specially emphasized that, It can remove general adhering garbage, such as mud, etc., the cleaning effect of sticky garbage is poor, and the removal effect of mopping and sweeping function is not considered). For the pickup function of garbage and water, relying on the carrying and clamping of the two cleaning rollers 1, the cleaning fins 2 of the cleaning roller 1 can use the surface to carry some garbage and dirty water during the rotation process. There is a triangle area in the lower part of the area) (the size of the triangle area can be adjusted by adjusting the setting of the cleaning roller 1 parameter in the cleaning component, such as the diameter and center distance of the two, the degree of contact between the dirt inlet end and the working surface), and the circular rotation Where the cleaning fins 2 cannot reach, for some small garbage, it cannot be squeezed and clamped by the two cleaning rollers 1 at the same time. At this time, it is mainly picked up by two situations. One is the rotating cleaning fins 2 themselves. With a certain carrying force, the garbage and water will stick to the cleaning fins 2. Second, when the cleaning fins 2 are continuously rotating, the garbage and water will be knocked off or warped, so that they can be lifted by the clip. Take, especially after the cleaning fin 2 is scraped from the ground, the moment it leaves the ground, the end of the cleaning fin 2 produces a certain ejection acceleration effect, and the end of the cleaning fin 2 is the end away from the axis. The two cleaning rollers 1 are continuously knocked and transmitted, and the two cleaning rollers 1 are not in contact with each other, and the function of cleaning and picking up garbage and water can also be realized. In the cleaning assembly, the parameters of the two cleaning rollers 1 can be adjusted to adjust the size of the dirt inlet area 43, such as the diameter and center distance of the two, the degree of contact between the dirt inlet end and the working surface, and the height of the wheelbase. The size of the dirt intake area 43 should be adapted to the corresponding working environment. For example, when the garbage or waste mainly picked up is large (for example, garbage pickup similar to table tennis), the size of the dirt intake area 43 should be The adaptation can better realize the gripping, and avoid that the contamination entry area 43 is too small and the object to be picked cannot enter, or the contamination entry area 43 is too large, and the object to be picked up is not easy to be picked up or knocked off. When fitting, it is not required that the shape must be the same, and it can be considered that when the cleaning roller 1 is a rubber roller, the cleaning fin 2 has the ability to deform, and the actual items that can be gripped can be slightly larger than the size of the dirt inlet area 43 shown under static conditions. The center distance of the two cleaning rollers 1, the selection of specific parameters and the adaptation of the size of the dirt inlet area 43 can be determined according to experiments.

After the cleaning roller 1 carries garbage or water, it is separated again in the casing 4 to realize the self-cleaning of the cleaning roller 1. It can rely on the centrifugal force of rotation and the elastic throwing action of the object when the two cleaning fins 2 are squeezed and rotated. , the two cleaning rollers 1 squeeze each other in the middle. After the squeezing stage, the cleaning fins 2 will be elastically released and the resultant thrust of the cleaning fins 2 on the front and rear sides to the object will help throw the object. To achieve separation, the diameters of the two cleaning rollers 1 are different, and the center distance is different, the staggered extrusion area is different, and the final parabolic angle is also different. When the diameter of the cleaning roller 1 on the rear side is smaller than that of the cleaning roller 1 on the front side, the parabolic angle Pointing to the rear and upward also causes the cleaning roller 1 on the rear side to carry and transport more garbage and water in the upper area (here is one of the reasons for the structure of the removable upper scraper 25 described below, which can simplify the structure and reduce the resistance). The garbage bin 3 receives garbage and water, and the front end of the garbage bin 3 can approach or press into the rear side of the small cleaning roller 1b, so as to reduce the garbage and water to continue to rotate with the cleaning roller 1 .

5 , in this embodiment, an anti-drip plate 5 can also be added. The anti-drip plate 5 is arranged behind the small cleaning roller 1b. The anti-drip plate 5 mainly receives the water droplets thrown from the rear side of the small cleaning roller 1b and is not covered by the garbage bin 3 The addition of the anti-drip plate 5 can further improve the effect of no dripping and no residue on the rear side of the small cleaning roller 1b for the collected part or the water droplets escaping from the front end of the garbage bin 3 . As shown in FIG. 6 , the drip-proof plate 5 can be inclined and installed, and the drip-proof plate 5 can be installed on the casing 4 or at the front of the garbage bin 3 . The lower end of the drip-proof plate 5 may or may not be in contact with the end of the cleaning fins 2 of the small cleaning roller 1b, as long as the water droplets can be taken away by the cleaning fins 2. When the anti-drip plate 5 is in contact with the end of the cleaning fin 2, a small amount of water droplets contained on the anti-drip plate 5 can be carried by the end of the cleaning fin 2 again without falling, or it can be swept and dragged by the cleaning fin 2 again. It can also be ejected to the cleaning fins 2 within the effective scraping distance or on the front side thereof, and the anti-drip plate 5 can also be arranged horizontally and in contact with the small cleaning roller 1b, as shown in FIG. 6 .

7, in this embodiment, the garbage and water are separated from the cleaning roller 1, which can also be carried out by means of a scraping device, that is, adding a lower scraper 24, which is in tangential contact or pressing with the cleaning fins 2 of the small cleaning roller 1b. Rigid scraping, while the cleaning fin 2 hits the scraping end of the lower scraper 24, it can trigger the shaking or ejection of the end of the cleaning fin 2, which helps to separate the garbage and water from the cleaning fin 2, and finally the garbage and The water falls into the garbage bin 3 from the falling end of the lower scraper 24 , and the front end of the garbage bin 3 can receive the water droplets thrown by the small cleaning roller 1b and the dirt flowing from the falling end of the lower scraper 24 . Similarly, an upper scraper 25 can also be installed in the casing 4. The upper scraper 25 is used to clean the large cleaning roller 1a, and both the upper scraper 24 and the lower scraper 25 can be used as scraping devices.

The upper scraper 25 and the lower scraper 24 are installed on the upper and lower sides of the inner front of the casing 4, respectively, to realize the self-cleaning of the cleaning roller 1 for the large cleaning roller 1a and the small cleaning roller 1b, which can be selected according to the actual self-cleaning effect. Install the upper scraper 25 and the lower scraper 24, select and adjust the relationship between the upper scraper 25 or the lower scraper 24 and the cleaning fins 2 to match the spacing, or the tangential position contact or pressure contact, the degree of pressure contact is in In the rotating body of the cleaning roller 1, the maximum depth that the upper scraper 25 or the lower scraper 24 is pressed into (for example, in the use environment for cleaning larger garbage, the scraping end of the lower scraper 24 can be connected with the small cleaning roller 1b. The ends of the cleaning fins 2 have a certain distance to reduce the impact and friction between the two, and at the same time, it can prevent the separation of larger garbage. The judgment of the size of the garbage needs to consider the overall shape). The purpose of self-cleaning is that after separating the garbage and dirty water, the dirty part of the cleaning fin 2 can be scraped off relatively clean, and then it can carry very little dirty water and basically no garbage when it contacts the ground, so as to ensure that it can last for a long time. Sweep for a long time. In this embodiment, the upper scraper 25 can be vertically arranged and located at a vertically tangent position behind the large cleaning roller 1a, and the lower scraper 24 can be pressed into the small cleaning roller 1b by about 2 mm from the upper and rearward position of the small cleaning roller 1b.

In this embodiment, a primary filter 6 can also be added to form a water storage space 7 with the bottom of the garbage bin 3 to improve the experience of scraping the ground and collecting water. At this time, the water storage space 7 can be a water receiving device.

8-9, in this embodiment, the garbage bin 3 can be integrally arranged with the casing 4, and the rear end of the garbage bin 3 is opened and a sealing door 26 is installed.
