[0047] The present disclosure provides a cleaning device, which comprises a machine body, a cleaning brush assembly, a liquid spraying assembly, an inner wall assembly and an outer wall assembly. The cleaning brush assembly is arranged on the machine body and configured to clean a work surface. The liquid spraying assembly is arranged on the machine body and configured to spray cleaning liquid onto the cleaning brush assembly. The inner wall assembly is arranged around the outside of the cleaning brush assembly. The outer wall assembly is arranged around the outside of the inner wall assembly and cooperates with the inner wall assembly to form a sewage suction channel. When the cleaning device is in operation, the outer wall assembly is attached to the work surface to prevent sewage from flowing out. The sewage suction channel is configured to suck sewage through the gap between the bottom edge of the inner wall assembly and the work surface when the cleaning device is in operation.

[0048] Specifically, the working process of the cleaning device of the present disclosure can include the following steps:

[0049] Firstly, the user places the cleaning device on the work surface to be cleaned, and makes the outer wall assembly fully attached to the work surface to form a closed space, so as to enclose the inner components surrounded by the outer wall assembly and the cleaning brush assembly surrounded by the inner wall assembly in the closed space.

[0050] Secondly, the liquid spraying assembly starts to spray cleaning liquid onto the cleaning brush assembly.

[0051] At the same time, the cleaning brush assembly cooperates with the cleaning liquid to clean the work surface. The cleaning liquid mixes with the stains on the ground to form sewage, which is sucked into the sewage suction channel through the gap between the inner wall assembly and the work surface, and finally discharged into the sewage tank of the cleaning device or directly discharged into the sewer. The part of the sewage that is not sucked into the sewage channel in time is also confined in the closed area enclosed by the outer wall assembly and the work surface, and is gradually sucked into the sewage suction channel when the user drags the cleaning device to move on the work surface. In this way, the problem of the random flow of cleaning liquid and sewage to pollute the cleaned work surface is avoided to a certain extent, and the cleaning efficiency is improved, and the user experience is improved.

[0052] Especially, when the existing cleaning device cleans an inclined work surface such as a wall surface, the sewage generated during cleaning will flow along the work surface to a horizontal surface such as the ground, causing ground pollution. The user needs to clean the ground again, increasing the workload of the user and further affecting the user experience.

[0053] When the user uses the cleaning device of the present disclosure to clean an inclined work surface, the user can adjust the outer wall assembly provided with the sewage suction channel to be below the cleaning brush assembly (when the inclined work surface is a vertical work surface, the oblique lower side is the vertical lower side). Since the outer wall assembly is attached to the work surface at the oblique lower side of the cleaning brush assembly, the sewage generated during cleaning is blocked by the outer wall assembly and is sucked out by the sewage suction channel. In this way, the secondary pollution caused by the direct flow of sewage to the ground can be prevented to a certain extent, thereby improving the user experience.

[0054] In one embodiment of the present disclosure, at least the portion of the outer wall assembly forming the sewage suction channel is configured to be transparent, so that the user can observe the degree of clarification of the sewage in the sewage suction channel through the transparent outer wall assembly, and then determine whether the cleaning is completed according to the degree of clarification of the sewage.

[0055] For the convenience of understanding, the specific structure of the cleaning device of the present disclosure and its working principle will be described in detail below with reference to one embodiment. Figures 1 to 5

[0056] The present disclosure provides a cleaning device, which comprises a machine body, a cleaning brush assembly 1, a liquid spraying assembly, an inner wall assembly 2 and an outer wall assembly 3.

[0057] The machine body serves as a carrier and is configured to mount various functional elements required by the cleaning device, including at least the cleaning brush assembly 1, the liquid spraying assembly, the inner wall assembly 2 and the outer wall assembly 3.

[0058] It should be noted that the present disclosure is not limited to the cleaning device described in the embodiments of the present disclosure. Figure 1 Only the partial structure of the machine body of the cleaning device is shown, and the remaining parts are basically the same as the machine body of the existing cleaning device, which can be implemented by those skilled in the art based on the prior art, and thus will not be described herein.

[0059] The cleaning brush assembly 1 is arranged on the machine body and is configured to clean the working surface. Specifically, the cleaning brush assembly 1 comprises a brush body fixing member 11 and a brush body 12 arranged on the brush body fixing member 11, and the brush body 12 is used to clean the working surface. The brush body 12 can be a brush in the Figures 2 to 5 The material of the brush can be animal hair, plastic wire, rubber wire or metal wire, etc.

[0060] Specifically, the cleaning device of the present disclosure can clean the hard surface of a hard object and the soft surface of a soft object. The hard surface refers to the surface of an object with a hardness greater than that of the outer wall assembly 3, such as floor tiles, walls, table tops, etc. The soft surface refers to the surface of an object with a hardness less than that of the outer wall assembly 3, such as carpets, tapestries, etc.

[0061] When cleaning the hard surface of a hard object, the working surface is the hard surface. When cleaning the soft surface of a soft object, the outer wall assembly 3 abuts against the inside of the soft object, so that the surface surrounded by the abutting part of the outer wall assembly 3 and the soft object inside the soft object is the working surface. The cleaning brush assembly 1 is rotatably arranged on the machine body, so that the brush body 12 of the cleaning brush assembly 1 rotates relative to the machine body to brush the working surface.

[0062] ​The liquid spraying assembly is arranged on the machine body and is configured to spray the cleaning liquid onto the cleaning brush assembly 1. Specifically, the liquid spraying assembly comprises at least one liquid spraying port, a liquid spraying pipe 63, a cleaning liquid tank (not shown in the figure) and a liquid spraying member (not shown in the figure), the liquid spraying port is in communication with the cleaning liquid tank through the liquid spraying pipe 63, and the cleaning liquid in the cleaning liquid tank flows through the liquid spraying pipe 63 and is sprayed from the liquid spraying port to the cleaning brush assembly 1 under the action of the liquid spraying member.

[0063] It should be noted that the cleaning liquid used by the cleaning device of the present disclosure can be clean water, or a mixture of water and cleaning substances such as dishwashing liquid, and the liquid spraying member can be various pumps for conveying liquid.

[0064] As shown in Figures 3 to 5 The inner wall assembly 2 is arranged around the outside of the cleaning brush assembly 1, and the outer wall assembly 3 is arranged around the outside of the inner wall assembly 2. The inner wall assembly 2 and the outer wall assembly 3 cooperate to form a sewage suction channel 4, at least part of the bottom edge of the inner wall assembly 2 is higher than the bottom edge of the outer wall assembly 3, and when the cleaning device is working, sewage is sucked out from the gap formed by the height difference between the inner wall assembly 2 and the outer wall assembly 3.

[0065] Among them, the inner wall assembly 2 has a certain blocking effect on the cleaning liquid to prevent the cleaning liquid from being immediately recovered after being sprayed; when the cleaning device is working, the outer wall assembly 3 is attached to the working surface to form a closed space, thereby preventing the sewage generated during cleaning from overflowing from the outer wall assembly 3.

[0066] The cleaning device of the present disclosure can also include a sewage tank (not shown in the figure) and a liquid suction member (not shown in the figure), the sewage tank is in communication with the sewage tank through the sewage suction channel 4, and the sewage can flow into the sewage suction channel 4 through the above-mentioned gap 5 under the action of the negative pressure provided by the liquid suction member, and then flow into the sewage tank, thereby realizing the recovery of the sewage.

[0067] Specifically, the cleaning process of the cleaning device of the present disclosure can include the following steps:

[0068] Firstly, the user places the cleaning device on the working surface to be cleaned, and makes the outer wall assembly 3 completely attached to the working surface to form a closed space, so as to enclose the inner assembly 2 surrounded by the outer wall assembly 3 and the cleaning brush assembly 1 surrounded by the inner wall assembly 2 in the closed space;

[0069] Secondly, the liquid spraying assembly starts to spray the cleaning liquid onto the cleaning brush assembly 1;

[0070] At the same time, the cleaning brush assembly 1 cooperates with the cleaning liquid to clean the working surface, the cleaning liquid mixes with the dirt on the ground to form sewage, the sewage is sucked into the sewage suction channel 4 from the gap between the inner wall assembly 2 and the working surface, and finally is discharged into the sewage tank of the cleaning device or directly discharged into the sewer. The part of the sewage that is not sucked into the sewage suction channel in time is also limited in the closed area surrounded by the outer wall assembly 3 and the working surface, and is gradually sucked into the sewage suction channel when the user drags the cleaning device to move on the working surface. In this way, the problem of the cleaning liquid and the sewage flowing randomly to pollute the cleaned working surface is avoided to a certain extent, the same working surface does not need to be cleaned repeatedly, the cleaning efficiency is improved, and the user experience is improved.

[0071] Especially, when the existing cleaning device cleans the inclined working surface such as a wall surface, the sewage generated by cleaning flows along the working surface to the ground or the like, causing ground pollution, and the user needs to clean the ground again, increasing the workload of the user and further affecting the user experience.

[0072] When the user uses the cleaning device of the present disclosure to clean the inclined working surface, the user can adjust the outer wall assembly 3 provided with the sewage suction channel to be obliquely below the cleaning brush assembly. Since the outer wall assembly 3 is in abutment with the working surface obliquely below the cleaning brush assembly (obliquely below when the inclined working surface is a vertical working surface), the sewage generated by cleaning is blocked by the outer wall assembly 3 and is sucked out by the sewage suction channel. In this way, the secondary pollution caused by the direct flow of the sewage to the ground can be prevented to a certain extent, so as to improve the user experience.

[0073] In an embodiment of the present disclosure, as shown in Figures 2 to 5 The entire bottom edge of the inner wall assembly 2 and the working surface form a gap 5, that is, the bottom edge of the inner wall assembly 2 is higher than the bottom edge of the outer wall assembly 3 in the direction of Figure 4 The bottom edge of the inner wall assembly 2 can be flush, so that the processing of the internal assembly can be facilitated. In another embodiment of the present disclosure, part of the bottom edge of the inner wall assembly 2 and the working surface form a gap 5, and the other part of the bottom edge is flush with the bottom edge of the outer wall assembly 3. In this way, the blocking effect of the inner wall assembly 2 can be improved, the cleaning liquid can stay in the inner wall assembly 2 for a longer time, and the utilization rate of the cleaning liquid can be improved.

[0074] As described above, the user can determine whether the current cleaning of the working surface is completed according to the clarification degree of the sewage. In order to facilitate the user to observe the clarification degree of the sewage, in an embodiment of the present disclosure, at least the part of the outer wall assembly 3 forming the sewage suction channel 4 is made of transparent material. Since at least the part of the outer wall assembly 3 forming the sewage suction channel 4 is made of transparent material, the user can see the sewage in the sewage suction channel 4 through the transparent outer wall assembly 3, and can easily obtain the clarification degree of the sewage.

[0075] The cleaning device of the present disclosure can be used to clean a horizontal working surface, and can also be used to clean an inclined working surface, wherein the inclined working surface is a working surface inclined at an angle to the horizontal surface, such as a vertical working surface inclined at an angle of 90 degrees to the horizontal surface. When cleaning the horizontal working surface and the inclined working surface, the same sewage suction channel 4 can be used, or different sewage suction channels 4 can be used to suck out the sewage. Moreover, when cleaning the horizontal working surface and the inclined working surface, only one sewage suction channel 4 can be used, or multiple (including two) sewage suction channels 4 can be used.

[0076] According to one embodiment of the present disclosure, as shown in Figure 6 , the cleaning device of the present disclosure has only one sewage suction channel 4.

[0077] The sewage suction port of the sewage suction channel 4 can have various shapes. In one embodiment of the present disclosure, the sewage suction port of the sewage suction channel 4 is a fan ring or a ring. The ring is the part left after a large circle is cut with a concentric small circle, and the fan ring is a part of the ring cut by a sector, the central angle of the ring is 360°, and the central angle of the fan is less than 360°. Figure 6 The sewage suction port of the sewage suction channel inis a fan ring, and the central angle thereof is 180°.

[0078] When the sewage suction port of the sewage suction channel 4 is a fan ring or a ring, the sewage suction port of the sewage suction channel 4 can be directly formed by the gap between the ring-shaped inner wall assembly 2 and the ring-shaped outer wall assembly 3, which is relatively simple.

[0079] Further, according to one embodiment of the present disclosure, the number of sewage suction channels 4 is two, of which one is located at the rear of the cleaning device and can be used to absorb sewage when the cleaning device moves forward in; the other is located at the front of the cleaning device and can be used to absorb sewage when the cleaning device moves backward in. Figure 7 Figure 8 The above-mentioned front and rear are based on the direction inand. Figure 7 Figure 8

[0080] When there are multiple sewage suction channels 4, the cleaning device of the present disclosure can use different sewage suction channels 4 to absorb sewage under different circumstances. In order to enable the user to observe the sewage in the sewage suction channel when the cleaning device selects any sewage suction channel to absorb sewage, according to one embodiment of the present disclosure, as shown in and , the outer wall assembly 3 of the present disclosure comprises a first outer wall sub-body 31 and a second outer wall sub-body 32 which can be detachably connected to each other. Moreover, the first outer wall sub-body 31 comprises a transparent first outer wall sub-body 31 and an opaque first outer wall sub-body 31. Similarly, the second outer wall sub-body 32 comprises a transparent second outer wall sub-body 32 and an opaque second outer wall sub-body 32. Figure 7 Figure 8

[0081] Thus, when the cleaning device uses the sewage suction passage on the side of the first outer wall part 31 to suck sewage, the user can use the transparent first outer wall part 31. Conversely, when the cleaning device uses the sewage suction passage on the side of the second outer wall part 32 to suck sewage, the user can use the transparent second outer wall part 32. Of course, if the first outer wall part 31 and the second outer wall part 32 are both provided with a sewage suction passage, the user can use the transparent first outer wall part 31 and the transparent second outer wall part 32.

[0082] As mentioned above, the working surface that can be cleaned by the cleaning device of the present disclosure includes a horizontal working surface and an inclined working surface.

[0083] In order to adapt to different application scenarios and meet the needs of users to clean different types of working surfaces, according to an embodiment of the present disclosure, in combination with Figure 4 and Figure 5 The liquid spraying assembly of the present disclosure includes a horizontal surface liquid spraying port 61 and an inclined surface liquid spraying port 62.

[0084] As Figure 4 shown, in the present embodiment, the horizontal surface liquid spraying port 61 of the present disclosure is configured to be located above the cleaning brush assembly 1 in the height direction when the cleaning device cleans a horizontal working surface, i.e., the height of the horizontal surface liquid spraying port 61 is higher than the height of the cleaning brush assembly 1. It should be noted that Figure 4 the direction indicated by the arrow in the above is the flow direction of the cleaning liquid, and the aforementioned height direction is based on the height direction in Figure 4 .

[0085] Thus, when the cleaning device cleans a horizontal working surface, the horizontal surface liquid spraying port 61 directly sprays cleaning liquid onto the brush body 12 of the cleaning brush assembly 1, and then the cleaning liquid can be spread over the current working surface by controlling the rotation of the brush body 12.

[0086] As Figure 5 shown, in the present embodiment, the inclined surface liquid spraying port 62 of the present disclosure is configured to be located above the cleaning brush assembly 1 in the height direction when the cleaning device cleans an inclined working surface. It should be noted that Figure 5 the direction indicated by the arrow in the above is the flow direction of the cleaning liquid, and the aforementioned height direction is based on the height direction in Figure 5 .

[0087] When the cleaning device cleans an inclined working surface, the cleaning liquid sprayed from the inclined surface liquid spraying port 62 flows onto the brush body 12 of the cleaning brush assembly 1 under the action of gravity, and then the cleaning liquid is brought into full contact with the brush body 12 by controlling the rotation of the brush body 12, so as to ensure the spreading amount of the cleaning liquid on the working surface, and even to spread over the entire working surface. Thus, the utilization rate of the cleaning liquid can be improved, and the cleaning capacity of the cleaning device can be enhanced.

[0088] Of course, in other embodiments of the present disclosure, the liquid spray outlets can also only include the horizontal liquid spray outlets 61 or only include the inclined liquid spray outlets 62.

[0089] According to one embodiment of the present disclosure, continuing to refer to Figure 5 , the inclined liquid spray outlets 62 of the cleaning device of the present disclosure are arranged in the gap between the inner wall assembly 2 and the outer wall assembly 3.

[0090] In this way, the cleaning device of the present disclosure ingeniously utilizes the structural features of the cleaning device, arranges the inclined liquid spray outlets 62 in the gap between the inner wall assembly 2 and the outer wall assembly 3, does not occupy the space in the inner wall assembly 3, avoids interference with the position of the cleaning brush assembly 1, and can install a large enough cleaning brush assembly 1 in the limited space to ensure the cleaning ability of the cleaning device.

[0091] According to one embodiment of the present disclosure, continuing to refer to Figure 2 , the cleaning device of the present disclosure arranges multiple liquid spray outlets on the same liquid spray plate, the liquid spray plate is communicated with the liquid spray tank through one main liquid spray pipe, and the liquid spray plate is further divided into multiple branch liquid spray pipes which are communicated with each liquid spray outlet, so that the liquid spray pipe 63 and the liquid spray outlet can be more conveniently arranged.

[0092] In detail, as Figure 2 shown in one embodiment of the present disclosure, the cleaning device of the present disclosure is provided with a horizontal liquid spray plate and an inclined liquid spray plate, the horizontal liquid spray plate is provided with multiple horizontal liquid spray outlets 61, and the inclined liquid spray plate is provided with multiple inclined liquid spray outlets 62.

[0093] In order to improve the cleaning effect, in one embodiment of the present disclosure, the cleaning device of the present disclosure further comprises a driving assembly configured to drive the brush body 12 to move by driving the brush body fixing member 11 to move.

[0094] In this way, when the cleaning device works, the cleaning brush assembly 1 thereof can move on the working surface relative to the machine body, which can better remove stubborn stains on the working surface, thereby improving the working effect of the brush body 12, and can also make the cleaning liquid fully contact with the brush body 12, so that the brush body 12 carrying the cleaning liquid moves and can be coated on the entire working surface, thereby improving the utilization rate of the cleaning liquid and the cleaning ability of the cleaning device.

[0095] It should be noted that the driving assembly can drive the brush body 12 to move in various forms, such as driving the brush body 12 to translate on the working surface, driving the brush body 12 to roll on the working surface, or driving the brush body 12 to rotate on the working surface.

[0096] According to one embodiment of the present disclosure, as Figure 2As shown, the driving assembly includes a transmission shaft 72 and a motor 71, the transmission shaft 72 is connected with the brush body fixing member 11, and the motor 71 is configured to drive the brush body fixing member 11 to rotate by driving the transmission shaft 72 to rotate, and then drive the brush body 12 to rotate.

[0097] As described above, when the cleaning device works, the bottom edge of the outer wall assembly 3 needs to be attached to the working surface to close the space, so as to confine the sewage in the area enclosed by the outer wall assembly 3 and the working surface, and prevent the sewage from flowing into the cleaned working surface at will, causing secondary pollution.

[0098] In order to ensure the attachment of the outer wall assembly 3 and the working surface, according to an embodiment of the present disclosure, the bottom edge of the outer wall assembly 3 is a soft bottom edge. When the cleaning device works, it uses the characteristics of the soft bottom edge to press the inner and outer wall assemblies 3 on the working surface by external force, which can basically ensure that the bottom edge of the outer wall assembly 3 is completely attached to the working surface. If there is a pit on the working surface, the outer wall assembly 3 is deformed after being extruded to fill the pit, thereby implementing 360-degree omnidirectional blocking of the sewage.

[0099] As described above, according to an embodiment of the present disclosure, part of the bottom edge of the inner wall assembly 2 of the present disclosure is higher than the bottom edge of the outer wall assembly 3, and the suction channel 4 can use the gap 5 formed between the two as a sewage suction port to suck sewage.

[0100] In order to improve the sewage suction capacity of the suction channel, according to an embodiment of the present disclosure, all the bottom edges of the inner wall assembly 2 of the present disclosure are higher than the bottom edges of the outer wall assembly 3. In this way, the sewage can quickly flow out from various angles from the area where the cleaning brush assembly is located for the suction channel to suck.

[0101] It can be understood that the cleaning device of the present disclosure can be used to clean hard working surfaces such as floors, and can also be used to clean soft working surfaces such as carpets.

[0102] In order to improve the cleaning ability of the cleaning device of the present disclosure for cleaning soft working surfaces, according to an embodiment of the present disclosure, the cleaning device of the present disclosure is configured such that the bottom edges of the inner wall assembly 2 and the outer wall assembly 3 are attached to the soft working surface. That is, the height difference between the inner wall assembly 2 and the outer wall assembly 3 of the present disclosure is equal to or less than the deformation amount of the soft working surface.

[0103] In this way, the cleaning liquid can be completely soaked in the soft working surface before being sucked out by the suction channel,
