[0041] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0042] In a first aspect, the present embodiment provides a cleaning tray. FIG1 is a schematic structural diagram of a cleaning tray provided in the present embodiment. FIG2 is a schematic structural diagram of a cleaning tray body provided in the present embodiment from a first perspective. FIG3 is a schematic structural diagram of a cleaning tray body provided in the present embodiment from a second perspective.

FIG6 is a schematic structural diagram of the bottom of a filter screen provided in the present embodiment.

[0043] As shown in Figures 1 to 6, the cleaning disk of this embodiment includes: a cleaning disk body 1 and a filter 2. The cleaning disk body 1 includes a cloth washing area 11 and a non-cloth washing area 12. The non-cloth washing area 12 is located on the periphery of the cloth washing area 11. The non-cloth washing area 12 is higher than the cloth washing area 11. The disk surface of the cloth washing area 11 includes at least one scraper assembly 3. The filter 2 is disposed on the disk surface of the cloth washing area 11. The filter 2 includes a bottom plate 21 and a raised portion 22. The bottom plate 21 and the side surfaces of the raised portion 22 include multiple filter holes 4.

[0044] In some examples, as shown in FIG1 , the cloth washing area 11 includes two scraper assemblies 3 on its disk surface. Each scraper assembly includes a first scraper 31, a second scraper 32, and a third scraper 33. The first scraper 31, the second scraper 32, and the third scraper 33 are radially arranged. This arrangement allows for effective cleaning of the mop as it rotates.

[0045] For example, as shown in FIG1 , the first scraping bars 31 of the two scraping bar assemblies 3 are parallel to each other, and the filter 2 is located between the first scraping bars 31 of the two adjacent scraping bar assemblies 3. Placing the filter 2 between the first scraping bars 31 of the two adjacent scraping bar assemblies 3 can increase the ability of the filter 2 to collect dirt, thereby improving the filtering capacity of the filter 2.

[0046] In some examples, as shown in Figures 1 and 4, the raised portion 22 of the filter screen 2 is provided with a mounting opening 2211. The float end of the liquid level detection device 5 extends from the mounting opening 2211 above the bottom plate 21 of the filter screen 2 to detect the liquid level in the cleaning pan. In this embodiment, the raised portion 22 is provided, and the liquid level detection device 5 is disposed within the raised portion 22. The raised portion 22 can effectively filter dirt and protect the liquid level detection device 5.

[0047] In some examples, as shown in Figure 1, the non-cloth-washing area 12 is located on the periphery of the cloth-washing area 11, and the width of the non-cloth-washing area 12 located behind and on both sides of the cloth-washing area 11 is larger, and the width of the part located in front of the cloth-washing area 11 is smaller. Such an arrangement can not only improve the stability of the installation of the cleaning disc in the base station, but also make the cloth-washing area 11 more compatible with the sweeper, effectively reduce the dirty area caused by cloth washing, and thus help reduce the dirt residue on the surface of the cleaning disc. It is understandable that although the non-cloth-washing area of ​​this embodiment presents a certain width, in its embodiment, the non-cloth-washing area can also be a thin wall arranged around the cloth-washing area. Such an arrangement can reduce the installation space required for the cleaning disc body, which is conducive to reducing the volume of the cleaning base station.

[0048] The cleaning disk of this embodiment includes a cleaning disk body 1 and a filter 2. The cleaning disk body 1 includes a cloth washing area 11 and a non-cloth washing area 12. The non-cloth washing area 12 is located on the periphery of the cloth washing area 11 and is higher than the cloth washing area 11, which can effectively reduce the area of ​​dirt caused by cloth washing, thereby reducing the dirt residue on the surface of the cleaning disk. The filter 2 includes a bottom plate 21 and a raised portion 22. The bottom plate 21 is arranged on the disk surface of the cloth washing area 11, and filter holes 4 are provided on the bottom plate 21 and the side of the raised portion 22, which effectively increases the filtration area, so that the filter has a better ability to collect dirt, thereby reducing the amount of dirt on the cleaning disk and reducing the frequency of filter cleaning and maintenance.

[0049] In some embodiments, as shown in FIG. 1 , the surface of the cloth washing area 11 has a slope, and is inclined from the periphery of the cloth washing area 11 toward the filter screen 2 .

[0050] In some examples, as shown in Figure 2, the cloth washing area 11 includes a filter installation area 111, a first area 112 and a second area 113. The filter 2 is arranged in the filter installation area 111, which is the low point of the cloth washing area 11. The first area 112 is located on both sides of the filter installation area 111 and is inclined toward the filter installation area 111, with an inclination angle of 10° to 15°. The second area 113 is located in front of the filter installation area 111 and the first area 112 and is inclined toward the filter installation area 111, with an inclination angle of 8° to 13°. This arrangement enables the sewage in the cleaning tray to converge to the filter installation area 111. Preferably, the inclination angle of the first area 112 is 13.5°, and the inclination angle of the second area 113 is 10.5°.

[0051] In some examples, as shown in Figures 2 and 3, the cloth washing area 11 includes two scraper assemblies 3, each scraper assembly 3 including a first scraper 31, a second scraper 32, and a third scraper 33. The two scraper assemblies 3 are symmetrically arranged. The filter installation area 111 is located between the two first scraper bars 31, and the two first scraper bars 31 extend to the edge of the cloth washing area 11. The two third scraper bars 33 extend outward from the two first scraper bars 31 and extend to the edge of the cloth washing area 11. The first scraper bars 31 and the third scraper bars 33 of each scraper assembly 3 enclose a first area 112. The two second scraper bars 32 extend inward from the two first scraper bars 31 until the two second scraper bars 32 intersect. The second scraper bars 32 and the third scraper bars 33 of the two scraper assemblies 3 enclose a second area 113. This arrangement enables the scraper assembly 3 to effectively clean the mop and allows dirty water from each area to be collected in the filter installation area 111.

[0052] In some examples, as shown in Figures 2 and 3, the upper surfaces of the first scraper bar 31, the second scraper bar 32, and the third scraper bar 33 include multiple protrusions. This arrangement can increase the contact area between the mop and the scraper bar assembly 3, which is conducive to improving the self-cleaning effect of the mop.

[0053] The surface of the cloth washing area 11 of this embodiment has a slope, and is inclined from the four sides of the cloth washing area 11 toward the filter 2. When the mop rotates, the dirt in the sewage is stirred and flushed to the area where the filter 2 is located, thereby reducing the dirt residue on the surface of the cloth washing area 11.

[0054] In some embodiments, as shown in FIGS. 1 to 3 , the edge of the cloth washing area 11 is flush with the upper surface of the scraper bar assembly 3 .

[0055] In some examples, as shown in Figures 2 and 3, the filter mounting area 111 is lower than the upper surface of the first scraper bar 31. The upper surface of the first scraper bar 31 is flush with the edge height of the first area 112. The upper surface of the third scraper bar 33 is flush with the edge height of the first area 112 and / or the second area 113. The upper surface of the second scraper bar 32 is flush with the edge height of the second area 113. This arrangement increases the contact area between the first and second areas 112, 113 and the mop. When cleaning the mop, the first scraper bar 31 prevents the mop from carrying dirt collected in the filter mounting area 111 to the first and second areas 112, 113. The edges of the first and second areas 112, 113 are flush with the upper surface of the scraper bar assembly 3, allowing the mop to clean the surfaces of the first and second areas 112, 113 during the cleaning process. This helps reduce residual dirt on the dish surface.

[0056] The edge of the cloth washing area 11 of this embodiment is flush with the upper surface of the scraper assembly 3, which can increase the contact area between the mop and the dish surface during self-cleaning and reduce dirt residue on the dish surface.

[0057] In some embodiments, as shown in FIG6 , a support member 211 is provided at the bottom of the filter screen 2 . The support member 211 is supported on the disk surface of the cloth washing area 11 .

[0058] In some examples, as shown in FIG6 , the bottom of the filter screen 2 includes five support members 211, which are located around and in the middle of the filter screen 2. This arrangement can provide uniform support for the filter screen 2, making the gap between the filter screen 2 and the surface of the cloth washing area 11 more uniform. This is conducive to the circulation of sewage and helps reduce the amount of residual water. However, it is understandable that in other embodiments, the number of support members 211 can be less than five or more than five. The specific number can be set according to actual use requirements, and this embodiment does not impose too many restrictions on this.

[0059] For example, as shown in FIG6 , the support member 211 is cylindrical. This configuration facilitates processing and stabilizes the model. However, it should be noted that in other embodiments, the support member 211 may also adopt other shapes, such as a prism, a truncated pyramid, a truncated cone, or other irregular shapes.

[0060] In some examples, referring to FIG6 , the height of the support member 211 is 2 to 5 mm. This arrangement provides a reasonable height and is beneficial to the stability of the structure. Preferably, the height of the support member 211 is 3 mm.

[0061] The filter screen 2 of this embodiment is placed on the disk surface of the cloth washing area 11 through the support member 211, which reduces the contact area between the filter screen 2 and the disk surface of the cloth washing area 11 and increases the gap between the filter screen 2 and the disk surface of the cloth washing area 11, which is beneficial to reducing the residual water.

[0062] In some embodiments, as shown in FIG4 , the bottom plate 21 of the filter screen 2 is arc-shaped and gradually concave from the periphery to the middle.

[0063] 1 to 6, the shape of the bottom plate 21 of the filter 2 is adapted to the filter mounting area 111 of the cloth washing area 11 on the cleaning disk body 1. This arrangement can make the gap between the bottom plate 21 of the filter 2 and the surface of the cloth washing area 11 more uniform.

[0064] The bottom plate 21 of the filter screen 2 of this embodiment is curved, with a raised portion 22 located at the lowest point of the bottom plate 21. The inner side of the raised portion 22 is used to mount a sewage pump, facilitating the removal of sewage and reducing residual water. The filtering action of the raised portion 22 prevents large debris from being drawn into the sewage pump, thereby preventing blockage of the sewage pump or sewage pipe. Furthermore, the lowest end of the sewage pump's outlet is flush with or lower than the lowest end of the filter screen 2 and higher than the bottom plate. In other words, the lowest end of the sewage pump's outlet is close to the bottom of the filter screen mounting area 111, facilitating the extraction of water collected at the bottom of the filter screen mounting area 111.

[0065] In some embodiments, as shown in FIG5 , the bottom plate 21 of the filter screen 2 includes a notch 212. The notch 212 is used to accommodate a sewage extraction pipe. The raised portion 22 includes a sidewall 221 and a top plate 222. The sidewall 221 is disposed along the edge of the notch 212. The top plate 222 is disposed on top of the sidewall 221. The sidewall 221 includes a plurality of filter holes 4.

[0066] In some examples, as shown in Figure 5, the notch 212 is formed by the edge of the bottom plate 21 being recessed inward. The notch 212 is square in shape, with three edges. Sidewalls 221 are positioned along the edges of the notch 212. The side of the sidewall 221 facing the notch 212 accommodates a sewage extraction pipe. This arrangement allows the sidewall 221 to filter sewage from the cleaning pan, preventing large debris from being drawn into the sewage extraction pipe.

[0067] In some examples, as shown in FIG5 , the top plate 222 is disposed on top of the side wall 221 but does not safely cover the gap 212. This arrangement can provide space for the installation of a sewage pumping pipe.

[0068] In some examples, as shown in Figures 1 and 5, the top plate 222 further includes a clearance groove 2221. Providing the clearance groove 2221 on the top plate 222 can provide space for the installation of the liquid level detection device 5.

[0069] The filter screen 2 of this embodiment forms a space for accommodating the sewage pumping pipe through the cooperation of the bottom plate 21 and the raised portion 22, and surrounds the sewage pumping pipe within the filter screen 2, which can achieve a good sewage collection effect and effectively filter out large debris in the sewage to prevent large debris from entering the sewage pumping pipe.

[0070] In some embodiments, as shown in Figures 2 to 5, the cleaning tray body 1 includes a clamping portion 7 and at least one socket 6. The filter screen 2 includes a buckle 9 and at least one insert 8. Each insert 8 is inserted into a socket 6. The buckle 9 is clamped to the clamping portion 7.

[0071] In some examples, as shown in Figure 4, the buckle 9 and the insert block 8 are respectively located on opposite sides of the bottom plate 21 of the filter screen 2. Such an arrangement can make the fixation of the filter screen 2 more stable and reliable.

[0072] For example, as shown in FIG4 , the filter screen 2 includes a buckle 9 and two inserts 8. The buckle 9 is located on the side of the bottom plate 21 away from the raised portion 22, and the two inserts 8 are located on the opposite side of the buckle 9 and distributed on the left and right sides of the raised portion 22. This arrangement can form a triangular fixation, making the filter screen 2 more stable.

[0073] In some examples, as shown in Figures 4 and 5, the buckle 9 includes a main body 91 and a clamping block 92. The main body 91 is U-shaped, and one end of the main body 91 is connected to the bottom plate 21 of the filter 2. The clamping block 92 is arranged on the side of the main body 91 away from the bottom plate 21. When the filter 2 is fixed on the cleaning tray body 1, the plug 8 of the filter 2 is inserted into the socket 6 on the cleaning tray body 1, and the clamping block 92 on the main body 91 of the buckle 9 is clamped into the clamping portion 7 on the cleaning tray body 1. When the filter 2 is to be removed, pinch the two ends of the main body 91 so that the two ends of the main body 91 are close to each other, and the clamping block 92 can be pulled out from the clamping portion 7, then one side of the filter 2 can be lifted, and the plug 8 on the other side of the filter 2 can be pulled out from the socket 6 to complete the disassembly of the filter 2, which is very convenient and quick.

[0074] The filter screen 2 of this embodiment is fixed to the cleaning pan body 1 by the cooperation of the insert block 8 and the buckle 9, which is convenient for installation and removal, and more convenient for use and maintenance. The filter screen 2 of this embodiment is fixed to the cleaning pan body 1 by the cooperation of the buckle 9 and the insert block 8, which can ensure the secure installation of the filter screen 2 and facilitate removal, making it more convenient for use.

[0075] In a second aspect, this embodiment further provides a cleaning base station. Figure 7 is a schematic structural diagram of a cleaning base station provided by this embodiment. Figure 8 is an enlarged partial structural diagram of a cleaning base station provided by this embodiment.

[0076] As shown in Figures 7 and 8, the cleaning base station of this embodiment includes: a base station body 10 and the cleaning tray of the above embodiment. A recycling bin 101 is provided at the bottom of the base station body 10. The recycling bin 101 is used to accommodate the sweeper. The cleaning tray is disposed on the bottom plate of the recycling bin 101.

[0077] In some examples, as shown in FIG8 , a water groove is provided on the upper surface of the first scraper bar 31 of the scraper bar assembly 3. The base station body 10 includes a water inlet 103 located above the first scraper bar 31 for injecting cleaning water into the water groove on the first scraper bar 31. The cleaning water can overflow from the water groove and flow into the cloth washing area 11, allowing the water flow to be injected into the cleaning tray body 1 more smoothly. When the mop rotates, it can pass over the water groove on the upper surface of the first scraper bar 31, allowing the mop to absorb water and improve the cleaning effect.

[0078] The cleaning base station body 10 of this embodiment is equipped with a cleaning disc of the aforementioned embodiment. When the sweeper cleans the mop, water is poured into the water channel on the upper surface of the first scraper bar 31 through the water inlet 103 on the base station body 10. Simultaneously, the main unit rotates, thereby driving the mop to rotate, absorbing the water in the water channel on the upper surface of the first scraper bar 31 and removing the sticky water. The mop is then scraped by the raised points on the second and third scraper bars 32 and 33 to remove dirt from the mop. When cleaning the cleaning disc, water is first poured into the cleaning disc body 1 through the water inlet 103 on the base station body 10. Once the disc is full of water, the sweeper drives the main unit to rotate, causing the mop to rotate and stir the water, stirring up dirt. The dirt is then stirred up by the water flow, and the sewage pump is then driven to pump the dirt along with the sewage to the filter screen 2. After passing through the filter screen 2, the dirt enters the sewage pump pipe and is stored in the sewage tank or discharged directly into the sewer. This embodiment of the cleaning base station is equipped with a cleaning disc of the aforementioned embodiment and possesses all the beneficial effects of the aforementioned embodiments, which will not be further elaborated here. Therefore, when the cleaning machine station of this embodiment cleans the mop, dirt is not easily left, and the cleaning machine is easy to use.

[0079] In some embodiments, as shown in Figures 7 and 8, the cleaning base station further includes: at least one nozzle 102, which is disposed in the recovery bin 101. The nozzle 102 sprays toward the cloth washing area 11 of the cleaning tray.

[0080] In some examples, as shown in Figures 7 and 8, the base station body 10 also includes a water refill port (not shown) and a water injection port 103. The water refill port is used to add water to the water tank of the sweeper. The water injection port 103 is used to inject cleaning water into the cleaning pan. This arrangement helps improve the degree of automation, enabling automatic water refilling of the water tank and automatic water storage in the cleaning pan, making it more convenient to use.

[0081] In some examples, as shown in Figures 7 and 8, the base station body 10 includes two nozzles 102, which are located on the left and right sides of the cleaning tray body 2 and face the cloth washing area 11. This arrangement can utilize the lifting space of the carriage to use the two nozzles 102 to more comprehensively rinse the cloth washing area 11 from different directions, thereby improving the cleanliness of the tray surface.

[0082] In some examples, as shown in FIG8 , the spray tip of the nozzle 102 extends beyond the edge of the cleaning pan body 1 and to the top of the cleaning pan body 1. This arrangement prevents residual water from entering the gap between the cleaning pan and the cleaning tank, facilitating cleaning and maintenance of the cleaning tank.

[0083] This embodiment sets a nozzle 102 in the recovery bin 101, which can be used to flush the disk surface of the cloth washing area 11, so that the dirt remaining on the disk surface of the cloth washing area 11 can flow into the area of ​​the filter screen 2 with the flushing water, thereby preventing the dirt from remaining on the disk surface of the cloth washing area 11 and effectively improving the cleanliness of the disk surface of the cloth washing area 11.

[0084] Figure 9 is a schematic diagram of the structure of a nozzle provided in this embodiment. In some embodiments, as shown in Figure 9, the nozzle 102 includes at least two nozzles 1022, each of which faces a different direction and has a different angle between the spray direction and the ground.

[0085] In some examples, as shown in FIG9 , the nozzle 1022 is a flat nozzle, which can increase the pressure and expand the spray coverage area of ​​the nozzle 1022 .

[0086] In some examples, as shown in FIG9 , the nozzle 102 includes a nozzle 1021 and at least two nozzles 1022 , each of which is disposed on the nozzle 1021 . The nozzle 1021 is connected to a water source and is made of a hard rubber material, which provides better support for the nozzle 1021 .

[0087] In some examples, as shown in FIG9 , the nozzle 1022 is made of a soft rubber material. This configuration allows the nozzle 1022 to have a certain degree of elasticity. When the cleaning tray is installed, the nozzle 1022 can bend and automatically rebound to its original position, thereby facilitating installation and removal of the cleaning tray.

[0088] In some examples, as shown in Figures 9 and 10, the nozzle 102 includes two nozzles 1022. The spray directions of the two nozzles 1022 are at different angles to the horizontal plane. Furthermore, the projection of the two nozzles 1022 on the horizontal plane also forms an angle, so that the two nozzles 1022 of the nozzle 102 face different positions on the cleaning tray body 1. This arrangement allows for rinsing of various areas of the cloth washing area 11, encompassing a wide range of applications.

[0089] For example, as shown in FIG10 , each nozzle 102 includes two nozzles 1022, one of which is directed toward a first area 112 near the nozzle 102, and the other toward a second area 113. This arrangement enables the nozzle 102 to rinse both the first area 112 and the second area 113, effectively improving the cleanliness of the cloth washing area 11.

[0090] The nozzle 102 of this embodiment includes at least two nozzles 1022 . Each nozzle 1022 has a different orientation and a different angle between the spray direction of each nozzle 1022 and the ground. Therefore, the nozzle 102 can be applied to different disk surfaces and has a wide range of applications.

[0091] FIG11 is a flow chart of a water circuit control of a nozzle provided in this embodiment. In some embodiments, as shown in FIG11 , the cleaning base station further includes: a solenoid valve assembly. The solenoid valve assembly is used to control at least one nozzle 102 to cause at least one nozzle 102 to intermittently discharge water.

[0092] In some examples, as shown in Figure 11, the solenoid valve group includes a first solenoid valve, a second solenoid valve and a third solenoid valve. The inlet of the first solenoid valve is connected to the clean water source. The two outlets of the first solenoid valve are respectively connected to the inlet of the second solenoid valve and the inlet of the third solenoid valve. The two outlets of the second solenoid valve are respectively connected to the water replenishment port and the water injection port. The two outlets of the third solenoid valve are respectively connected to the two nozzles. In this way, the solenoid valve group consisting of the first solenoid valve, the second solenoid valve and the third solenoid valve can control the water replenishment port (not shown in the figure, the water replenishment port is used to supply water to the water tank in the sweeper), the water injection port 103 and the water circuit switches of the nozzles 102 on the left and right sides of the cleaning disc body.

[0093] Specifically, as shown in Figure 11, the water flow from the clean water source reaches the first solenoid valve under the drive of the peristaltic pump. The first solenoid valve controls the water flow to the second solenoid valve or the third solenoid valve. The second solenoid valve controls the water flow into the water supply port (not shown in the figure, the water supply port is used to supply water to the water tank in the sweeper) or the water injection port 103. The third solenoid valve controls the water flow to the left or right nozzle of the cleaning disc body. This configuration has a high degree of automation, is easy to use, and has a low demand on pump flow.

[0094] In this embodiment, by providing a solenoid valve group, water can be intermittently discharged from at least one nozzle 102, which is beneficial to reducing the demand for pump flow and thus achieving better energy-saving effects.
