Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cleaning household appliances, and particularly to a roller brush water supply structure and a cleaning device. Background Art

[0002] Currently, there are various styles of cleaning household appliance devices on the market, such as vacuum cleaners with mopping function, electric mops, etc. These vacuum cleaners with mopping function and electric mops need to supply water to their roller brushes during use. However, the current water supply methods for various vacuum cleaners with mopping function and electric mops on the market all adopt the method of point spraying water, and a plurality of spray holes are arranged above or on the side of the roller brush to spray water on the roller brush. However, this spraying method has defects, that is, the water spraying is uneven. The amount of water is more in the place close to the spray holes and less in the place far from the spray holes, resulting in uneven water distribution on the roller brush, affecting the mopping and cleaning effect, and poor user experience.

[0003] Therefore, it is very necessary to design a water supply structure that can supply water evenly to solve the problem of uneven water supply to the roller brush of the existing cleaning household appliance devices and improve the user experience. Summary of the Invention

[0004] In order to solve the problem of uneven water supply to the roller brush of the existing cleaning household appliance devices, the present application proposes a roller brush water supply structure and a cleaning device.

[0005] In a first aspect, the present invention proposes a roller brush water supply structure, comprising:

[0006] A water tank, which is integrally in a long strip shape and is arranged parallel to one side of the roller brush. An outlet is provided on the side wall of the water tank close to the roller brush. The outlet is in a long strip shape continuously extending along the length direction of the roller brush and its length is equal to the length of the roller brush;

[0007] A water permeable cotton, which is arranged in the water tank and completely fills the water tank. The top of the water permeable cotton corresponds to the outlet;

[0008] Wherein, the water in the water tank can permeate out through the water permeable cotton and flow to the roller brush along the whole outlet.

[0009] In an embodiment, the top of the water permeable cotton has a water permeable part extending into the outlet. Through this embodiment, the function of the water permeable part is to further guide the water flow. After the water flow permeates out through the water permeable part, it evenly flows to the roller brush along the outer surface of the water tank under the outlet.

[0010] In one embodiment, it further includes: a water guiding rib provided on the outer surface of the water tank and below the water outlet. The water guiding rib continuously extends along the length direction of the water outlet, and its free end extends outward to contact the surface of the roller brush, so as to guide the water flowing out from the water outlet to the roller brush. Through this embodiment, the water guiding rib can guide the water flow to the roller brush, and at the same time ensure that there is no gap between the water guiding rib and the surface of the roller brush, avoiding the leakage of water flow from the gap to the ground.

[0011] In one embodiment, the free end of the water guiding rib has a water guiding portion formed by bending downward, and the water guiding portion is in surface contact with the roller brush. Through this embodiment, the water guiding portion increases the contact area with the roller brush, and its water guiding and water leakage prevention effects are better.

[0012] In one embodiment, there is a certain interference between the free end of the water guiding rib and the surface of the roller brush to squeeze the roller brush. Through this embodiment, there is extrusion between the two due to the interference. In this way, the original moisture in the local contact part of the roller brush is discharged after being squeezed, improving the effect of absorbing the supplementary moisture guided by the water guiding rib; at the same time, there is local pressure at the contact part of the two, making the contact between the free end of the water guiding rib and the roller brush closer, further improving the anti-leakage effect.

[0013] In one embodiment, it further includes a water inlet assembly. The water inlet assembly includes a detachable water inlet joint and a water inlet pipe. The water inlet joint is detachably connected to the water inlet at the bottom of the water tank, and the water inlet pipe is connected to a water pump. Through this embodiment, the water inlet assembly is used to replenish the water in the water tank into the water tank in real time, and at the same time, based on the pumping power of the water pump, it also provides power for replenishing the water in the water tank to the roller brush.

[0014] In one embodiment, the water inlet joint is L-shaped. Through this embodiment, the water pumped by the water pump has a certain impact force. The L-shaped water inlet joint makes the water replenished from the water inlet pipe not directly flush into the water tank, but generates an impact at the corner of the L-shaped water inlet joint to reduce the kinetic energy of the water flow, avoiding the direct impact of the water flow on the water tank and the water-permeable cotton in the water tank, and ensuring the stability of the water supply structure.

[0015] In one embodiment, the water supply structure is arranged in a housing, and the housing has limiting parts respectively cooperating with the water tank and the water inlet assembly. Through this embodiment, because the water pumped by the water pump has a certain kinetic energy and impact force, limiting parts are arranged in the housing to ensure the fixation of the positions of the water tank and the water inlet assembly and the stability of the structure; at the same time, it is also convenient for the assembly with the water tank and the water inlet assembly.

[0016] In one embodiment, water squeezing ribs are further provided inside the housing. There is a certain interference between the water squeezing ribs and the surface of the roller brush to squeeze out some of the original moisture in the roller brush before replenishing water through the water tank. Through this embodiment, the water squeezing ribs can squeeze out the original moisture in the local part of the roller brush before the local part of the roller brush reaches the water tank, and then the roller brush can better absorb the clean water replenished from the water tank, so as to facilitate subsequent cleaning operations.

[0017] In a second aspect, the present invention provides a cleaning device, including a roller brush and further including the above-mentioned water supply structure.

[0018] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the object of the present invention can be achieved.

[0019] Compared with the prior art, the roller brush water supply structure and cleaning device provided by the present invention at least have the following beneficial effects:

[0020] The roller brush water supply structure and cleaning device of the present invention. The water supply structure is composed of a water changing tank and a water permeable cotton arranged in the water tank. On the one hand, a long strip-shaped water outlet equal to the length of the roller brush is arranged on the water tank, providing a structural basis for the uniform water supply of the roller brush; on the other hand, the water permeable cotton arranged in the water tank is used to break the surface tension of the water in the water tank, so that the water can flow uniformly from the whole water outlet to the roller brush, thus solving the problem of uneven water replenishment existing in the technical means adopted in the prior art.

Detailed implementation mode

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] An embodiment of the present invention provides a water supply structure for a rotating brush, including:

[0031] A water tank 1, which is integrally strip-shaped and is arranged parallel to one side of the rotating brush 5. A water outlet 11 is provided on the side wall of the water tank 1 close to the rotating brush 5. The water outlet 11 is strip-shaped and continuously extends along the length direction of the rotating brush 5, and its length is equal to the length of the rotating brush 5;

[0032] A permeable cotton 2 is arranged in the water tank 1 and completely fills the water tank 1. The top of the permeable cotton 2 corresponds to the water outlet 11;

[0033] Wherein, the water in the water tank 1 can permeate out from the permeable cotton 2 and flow to the rotating brush 5 along the whole water outlet 11.

[0034] Specifically, the prior art uses the method of spraying water to supply water to the rotating brush 5, and the problem of uneven water distribution existing in spraying water will affect the mopping effect of the rotating brush 5. The present invention improves the defect. The water supply structure of the present invention mainly includes two parts, namely the water tank 1 and the permeable cotton 2. As shown in the attached drawings Figures 1 to 3 shown, wherein the water tank 1 located on one side of the rotating brush 5 is used to store part of the water, and a strip-shaped water outlet 11 equal to the length of the rotating brush 5 is provided on its side wall; the permeable cotton 2 can absorb the water in the water tank 1 and make it flow evenly to the rotating brush 5 from the water outlet 11.

[0035] In the water supply structure of the present invention, the role of the permeable cotton 2 is particularly important. If there is no permeable cotton 2, when the water in the water tank 1 is stored to the height of the water outlet 11, due to the surface tension of the water surface, the water surface will be slightly higher than the height of the water outlet 11; when continuing to pump water into the water tank 1 through a water pump, the water in the water tank 1 continues to increase. After increasing to a certain extent, the water surface breaks through the action of the surface tension, and the water flows out from the water outlet 11. However, due to the action of the surface tension, the water will not flow out evenly from the whole water outlet 11, but will concentrate on a point that first breaks through the action of the surface tension. Therefore, in order to make the water flow out evenly along the whole water outlet 11, it is necessary to set the permeable cotton 2. Under the action of the permeable cotton 2, the surface tension of the water surface is broken, so that the water can evenly permeate through the permeable cotton 2 and flow out evenly along the whole water outlet 11, and water flows out at any position in the length direction of the water outlet 11, thus realizing the uniform water supply of the rotating brush 5.

[0036] It should be noted that the outer surface of the water tank 1 corresponding to the side of the water outlet 11 and the rim of the water outlet 11 should maintain a smooth surface to avoid blocking the water flow and affecting the uniformity of the water flow distribution.

[0037] Preferably, the top of the water-permeable cotton 2 has a water-permeable part 21 extending into the water outlet 11.

[0038] Specifically, as shown in the attached drawing Figure 2 The water-permeable part 21 is the part of the water-permeable cotton 2 extending from the side surface into the water outlet 11. Its function is to further guide the water flow. After the water flows out through the water-permeable part 21, it evenly flows along the outer surface of the water tank 1 under the water outlet 11 to the roller brush 5.

[0039] In one embodiment, it further includes:

[0040] The water guide rib 3 is arranged on the outer surface of the water tank 1 and below the water outlet 11. The water guide rib 3 extends continuously along the length direction of the water outlet 11, and its free end extends outward to contact the surface of the roller brush 5 to guide the water flowing out from the water outlet 11 to the roller brush 5.

[0041] Specifically, as shown in the attached drawing Figure 2 , the water guide rib 3 is arranged on the outer surface of the water tank 1 and extends outward to contact the surface of the roller brush 5, so as to be able to guide the water flow to the roller brush 5, and at the same time ensure that there is no gap between it and the surface of the roller brush 5 to avoid water leakage from the gap to the ground.

[0042] Furthermore, the free end of the water guide rib 3 has a water guide part 31 formed by bending downward, and the water guide part 31 is in surface contact with the roller brush 5.

[0043] Specifically, as shown in the attached drawing Figure 2 The water guide part 31 is integrally formed by bending the free end of the water guide rib 3. It is in surface contact with the roller brush 5 and its surface has a radian matching the circumferential surface of the roller brush 5. The water guide part 31 increases the contact area with the roller brush 5, and its water guiding and water leakage prevention effects are better.

[0044] Preferably, there is a certain interference between the free end of the water guide rib 3 and the surface of the roller brush 5 to squeeze the roller brush 5.

[0045] Specifically, there is a certain interference between the free end of the water guide rib 3 and the surface of the roller brush 5. As shown in the attached drawing Figure 2 , the free end of the water guide rib 3 squeezes the roller brush 5. In this way, when the roller brush 5 is squeezed, the original moisture in the local contact part is drained away, improving the effect of absorbing the supplementary moisture guided by the water guide rib 3; at the same time, there is local pressure at the contact part between the two, making the contact between the free end of the water guide rib 3 and the roller brush 5 closer, further improving the anti-leakage effect.

[0046] In one embodiment, it further includes a water inlet assembly 4. The water inlet assembly 4 includes a detachable water inlet joint 41 and a water inlet pipe 42. The water inlet joint 41 is detachably connected to the water inlet 12 at the bottom of the water tank 1, and the water inlet pipe 42 is connected to the water pump.

[0047] Specifically, as shown in the attached drawings Figures 1 to 3 As shown, the water inlet assembly 4 is integrally tubular. One end of it is connected to the water tank 1 and the other end is connected to the water pump, which is used to replenish the water in the water tank into the water tank 1 in real time. At the same time, based on the pumping power of the water pump, it also provides power for the water in the water tank 1 to be replenished to the roller brush 5. In addition, the water inlet 12 of the water tank 1 is opened at the bottom, so the position relationship between it and its water outlet 11 is not directly opposite. The water entering the water tank 1 from the water inlet 12 has a certain impact force. The non-opposite water inlet 12 and water outlet 11 prevent the water entering the water tank 1 from directly flowing out through the water-permeable cotton 2 from the water outlet 11, ensuring the uniformity of water absorption of the water-permeable cotton 2.

[0048] Preferably, the water inlet joint 41 is L-shaped.

[0049] Specifically, the water pumped by the water pump has a certain impact force. The L-shaped water inlet joint 41 makes the water replenished from the water inlet pipe 42 not directly rush into the water tank 1, but generate an impact at the L-shaped corner of the water inlet joint 41 to reduce the kinetic energy of the water flow and avoid the direct impact of the water flow on the water tank 1 and the water-permeable cotton 2 in the water tank 1, ensuring the stability of the water supply structure.

[0050] In addition, the water inlet joint 41 is not limited to the L shape, as long as it has a structure that can block the direct impact of the water flow. For example, the water inlet joint 41 can be composed of multiple parts with an arbitrary angle, or can be in the shape of a wave, a spiral, etc.

[0051] In one embodiment, the water supply structure is arranged in the housing 6, and the housing 6 is provided with a limiting part 61 that cooperates with the water tank 1 and the water inlet assembly 4 respectively.

[0052] Specifically, as shown in the attached drawings Figures 1 to 3 As shown, because the water pumped by the water pump has a certain kinetic energy and impact force, the limiting part 61 is arranged in the housing 6 to ensure the fixation of the positions of the water tank 1 and the water inlet assembly 4 and the stability of the structure; at the same time, it is also convenient for the assembly with the water tank 1 and the water inlet assembly 4.

[0053] In one embodiment, a water squeezing rib 7 is further arranged inside the housing 6. There is a certain interference between the water squeezing rib 7 and the surface of the roller brush 5 to squeeze out some of the original water in the roller brush 5 before replenishing water through the water tank 1.

[0054] Specifically, the water squeezing rib 7 can squeeze out the original moisture in a part of the roller brush 5 before this part of the roller brush 5 reaches the water tank 1. When applied to the corresponding cleaning device, the water squeezing rib 7 is actually also used to squeeze out the sewage generated by cleaning in the roller brush 5. Then, the roller brush 5 can better absorb the clean water supplemented by the water tank 1, so as to facilitate subsequent cleaning operations.

[0055] An embodiment of the present invention further provides a cleaning device, which includes a roller brush 5 and also includes the above-mentioned water supply structure, and thus has all the technical effects thereof.

[0056] Specifically, the cleaning device can be a vacuum cleaner that combines suction and mopping; it can also be various electric mops, including ordinary mops, steam mops, etc.; or other cleaning devices with a roller brush.
