Description

Technical Field

[0001] The present application belongs to the technical field of cleaning equipment, and in particular relates to a floor brush assembly of a surface cleaning device. Background Art

[0002] With the continuous development of cleaning devices, surface cleaning devices are widely used in people's lives, for example, sweeping robots, handheld cleaning devices, etc. These cleaning devices are usually equipped with roller brushes, which clean the cleaning surface by rotating the roller brush relative to the surface to be cleaned.

[0003] The cleaning device is usually provided with a roller brush cover covering the roller brush. When the cleaning device cleans the cleaning surface, the roller brush will throw dirt onto the roller brush cover, which requires the user to clean the roller brush cover, thereby increasing the cleaning burden of the user and affecting the user's experience. In order to reduce the cleaning burden of the user, some cleaning devices are provided with an arc edge on the roller brush cover, and the arc edge is arranged in a close fit with the cleaning member to avoid the problem that dirt is thrown onto the roller brush cover and the roller brush cover needs to be cleaned; however, when the bristles of the cleaning member rotate forward and pass through the water dividing plate, the bristles stretch from a compressed state to a fluffy state, and the residual water and fine particles inside the bristles will be thrown onto the surface to be cleaned on the front side of the floor brush assembly or the charging seat of the whole machine, which increases the cleaning difficulty for the user; at the same time, the arc edge is in an interference fit with the cleaning member in a fluffy state, causing the arc edge to be pushed up, so that the arc edge drives the floor brush assembly to separate from the surface to be cleaned or the risk of shaking or jumping, thereby affecting the running stability and cleaning effect of the floor brush assembly. Utility Model Content

[0004] The present application provides a floor brush assembly of a surface cleaning device to reduce the cleaning burden and difficulty of a user, ensure the operating stability and cleaning effect of the floor brush assembly, and improve the user's experience.

[0005] The technical solution adopted in this application is:

[0006] A floor brush assembly of a surface cleaning device comprises a shell having a roller brush assembly at the front end and a roller brush cover covering the roller brush assembly, the roller brush assembly comprising a roller provided with a cleaning member, a water dividing plate with a water supply port disposed toward the cleaning member being disposed below the roller brush cover, the water dividing plate comprising an arcuate surface concentric with the roller, the water supply port being disposed on the arcuate surface, an accommodating cavity being disposed in the shell, and also comprising an arcuate edge smoothly connected to the arcuate surface, the arcuate edge extending upward along the upper end of the arcuate surface and covering the roller brush assembly, the arcuate edge having a gradually increasing gap with the cleaning member.

[0007] Furthermore, a water tank is placed in the accommodating cavity, and the arc edge is formed by extending the front wall of the upper port of the water tank upward to the front end of the roller brush cover.

[0008] Furthermore, the arcuate surface is arranged to fit with the bristles of the cleaning member, and the center of the arcuate edge is arranged not lower than the center of the roller, so that there is a gap between the arcuate edge and the cleaning member in a fluffy state.

[0009] Furthermore, the arcuate edge is arranged concentrically with the roller, and the inner diameter of the arcuate edge is larger than the outer diameter of the cleaning member in the fluffy state, so that there is a gap between the arcuate edge and the cleaning member in the fluffy state.

[0010] Furthermore, a sealing member is provided at the lower end of the arc-shaped surface, and the water dividing plate is fixedly connected to the water tank. After the water tank is placed in the accommodating cavity, the sealing member seals the gap between the water dividing plate and the shell.

[0011] Furthermore, the sealing component includes a connecting portion connected to the water dividing plate and a sealing portion located at the bottom of the connecting portion. After the water tank is placed in the accommodating cavity, the sealing portion undergoes elastic deformation.

[0012] Furthermore, the arc edge is provided with a water-blocking rib, and the roller brush cover is provided with a sealing rib sealedly connected to the water-blocking rib, and the water-blocking rib is located directly above the center of the arc edge.

[0013] Furthermore, the water barrier divides the internal space of the water tank into a water storage cavity located at the rear end of the water barrier and a structural cavity located at the front end of the water barrier, and the structural cavity is provided with a drainage hole.

[0014] Furthermore, there is a gap between the roller brush cover and the front end of the arc-shaped edge to form the water drop hole;

[0015] And / or, the water drop hole is arranged on the arc-shaped edge and is located at the front end of the arc-shaped edge.

[0016] Furthermore, the arc extends upward to the roller brush cover to form a part of the roller brush cover, a water tank is placed in the accommodating cavity, and the roller brush cover is fixedly covered on the water tank to form an integrated structure with the water tank.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. By arranging an arc edge smoothly connected to the arc surface in the floor brush assembly, the arc edge extends upward along the upper end of the arc surface and covers the top of the roller brush assembly, and there is a gradually increasing gap between the arc edge and the cleaning member, so that when the surface cleaning device equipped with the floor brush assembly cleans the cleaning surface, the cleaning member throws the dirt or dirty liquid onto the arc edge, so as to avoid the situation that the cleaning member throws the dirt onto the roller brush cover or the surface to be cleaned on the front side of the floor brush assembly or on the charging base of the whole machine, so that the user can clean the arc edge alone, thereby reducing the cleaning burden and difficulty of the user, and at the same time avoiding the interference fit between the cleaning member and the arc edge, resulting in the risk of the arc edge being lifted upward, causing the arc edge to drive the floor brush assembly to leave the ground or shaking or jumping, thereby reducing the probability of affecting the operation and cleaning of the floor brush assembly due to the instability of the arc edge, thereby ensuring that the cleaning member can better contact with the surface to be cleaned and wipe it clean, thereby improving the user's experience.

[0019] 2. As a preferred embodiment of the present application, a water tank is placed in the accommodating cavity, and the arc-shaped edge is formed by the front wall of the upper port of the water tank extending upward to the front end of the roller brush cover. That is to say, the water tank is moved into the floor brush assembly to greatly reduce the thickness of the body, thereby making the body of the surface cleaning device equipped with the floor brush assembly thinner, which not only enables the floor brush assembly to enter a low space, but also enables the body to enter a relatively low area, thereby enabling the floor brush assembly to extend into the low space for dirty cleaning, thereby improving the flexibility of the surface cleaning device and improving the user's experience; at the same time, the arc-shaped edge is provided on the water tank, so that the user can clean the arc-shaped edge while cleaning the water tank, so as to reduce the cleaning burden of the user, and also enables the user to disassemble and assemble the arc-shaped edge while disassembling and assembling the water tank, so as to achieve the effect of facilitating the user to disassemble and assemble the arc-shaped edge, so as to further enhance the user's experience.

[0020] 3. As a preferred embodiment of the present application, the arc surface is arranged in a fit with the bristles of the cleaning member, so that when the roller drives the cleaning member to rotate forward, the bristles on the cleaning member can clean the water diversion plate, so as to improve the cleanliness of the water diversion plate and reduce the possibility of the water supply port being blocked by dirt, thereby ensuring that the water supply system supplies water to the cleaning member and the surface to be cleaned, so that the floor brush assembly can work stably, so as to ensure the cleaning effect and cleaning efficiency of the surface cleaning device, thereby further improving the user experience; the center of the arc edge is not lower than the center of the roller, so that there is a gap between the arc edge and the cleaning member in a fluffy state, and then when the bristles of the cleaning member rotate forward and pass through the water diversion plate, the bristles are stretched from a compressed state to a fluffy state, and the residual water and fine particles inside the bristles will be thrown onto the arc edge, which is convenient for users to disassemble and clean, thereby further improving the user experience. In addition, there is a gap between the arc-shaped edge and the cleaning piece in the fluffy state, which avoids the interference fit between the cleaning piece in the fluffy state and the arc-shaped edge, resulting in the arc-shaped edge being pushed upward, causing the arc-shaped edge to drive the floor brush assembly off the ground or the risk of shaking or jumping, thereby reducing the chance of the floor brush assembly being affected by the instability of the arc-shaped edge and affecting its operation and cleaning, thereby ensuring that the cleaning piece can better contact the surface to be cleaned and wipe it clean.

[0021] 4. As a preferred embodiment of the present application, a seal is provided at the lower end of the curved surface, and the water diversion plate is fixedly connected to the water tank so that the user can clean the water diversion plate while cleaning the water tank, avoiding the need to clean the water diversion plate and the water tank separately, thereby greatly reducing the cleaning burden of the user, so as to further improve the user's experience. The water tank is placed in the accommodating cavity, and the seal seals the gap between the water diversion plate and the shell to reduce the risk of sewage entering the shell from the gap between the water diversion plate and the shell, thereby ensuring the cleanliness of the shell, so as to further reduce the cleaning burden of the user, and further improve the user's experience.

[0022] 5. As a preferred embodiment of the present application, the sealing member includes a connecting portion connected to the water diversion plate and a sealing portion located at the bottom of the connecting portion. After the water tank is placed in the accommodating cavity, the sealing portion undergoes elastic deformation to increase the connection area between the sealing portion and the shell, thereby increasing the sealing effect of the sealing portion on the gap between the shell and the water diversion plate, thereby further reducing the risk of sewage entering the shell, thereby further increasing the cleanliness of the shell; at the same time, since the connection area between the sealing member and the shell is increased, the connection stability between the water diversion plate and the shell is increased, thereby ensuring the wetting effect of the water diversion plate on the cleaning member, thereby ensuring the cleaning effect of the surface cleaning device equipped with the floor brush assembly in the present application.

[0049] Reference Figures 1 to 13 A floor brush assembly of a surface cleaning device includes a shell 1 with a roller brush assembly 3 at the front end and a roller brush cover 2 covering the roller brush assembly 3, the roller brush assembly 3 includes a roller 31 with a cleaning member, a water supply port 41 is provided below the roller brush cover 2, a water dividing plate 4 is provided facing the cleaning member, the water dividing plate 4 includes an arcuate surface concentric with the roller 31, the water supply port 41 is provided on the arcuate surface, a accommodating cavity 12 is provided in the shell 1, the floor brush assembly also includes an arcuate edge 51 smoothly connected to the arcuate surface, the arcuate edge 51 extends upward along the upper end of the arcuate surface and covers the roller brush assembly 3, and the arcuate edge 51 has a gradually increasing gap with the cleaning member.

[0050] Since the arc edge 51 extends upward along the upper end of the arc surface and covers the roller brush assembly 3, and there is a gradually increasing gap between the arc edge 51 and the cleaning member, when the surface cleaning device equipped with the floor brush assembly cleans the cleaning surface, the cleaning member will throw dirt or dirty liquid onto the arc edge 51, so as to avoid the cleaning member throwing dirt onto the roller brush cover 2 or the surface to be cleaned on the front side of the floor brush assembly or the charging base of the whole machine, so that the user can clean the arc edge 51, thereby reducing the cleaning burden and difficulty of the user, and at the same time avoiding the interference fit between the cleaning member and the arc edge 51, resulting in the arc edge 51 being lifted upward, causing the arc edge 51 to drive the floor brush assembly off the ground or shaking or jumping, thereby reducing the probability of the operation and cleaning of the floor brush assembly being affected due to the instability of the arc edge 51, thereby ensuring that the cleaning member can better contact with the surface to be cleaned and wipe it clean, thereby improving the user's experience.

[0051] Embodiment 1:

[0052] Reference Figures 1 to 3, as a floor brush assembly of the surface cleaning device of the present application, it includes a housing 1 with a roller brush assembly 3 at the front end and a roller brush cover 2 covering the roller brush assembly 3, and the housing 1 is also provided with a running wheel. The roller brush assembly 3 includes a roller 31 provided with a cleaning member and a side plate 32 for mounting the roller 31 on the housing 1, the side plate 32 is arranged at one end of the roller 31, the front end of the housing 1 has a roller brush cavity, one side of the roller brush cavity is provided with a drive motor 13, and the drive motor 13 can be turned outward, when the drive motor 13 is turned out from the vicinity of the roller brush cavity, the other end of the roller 31 is sleeved on the drive motor 13, and then the roller 31 is pushed inward, and the side plate 32 is connected to the outer side wall of the housing 1, so that the roller 31 is installed in the roller brush cavity, and the roller brush assembly 3 is installed on the housing 1. The front wall of the housing 1, that is, the cavity wall of the roller brush cavity, is also provided with a sewage suction port, and a scraper strip is provided above the sewage suction port, and the sewage suction port is connected to the sewage bucket of the surface cleaning device through the sewage suction channel. When cleaning, the driving motor 13 drives the roller 31 to rotate, and the cleaning member on the roller 31 wipes the dirt on the surface to be cleaned. The scraper strip continuously scrapes the cleaning member, and the dirty liquid or dirt on the cleaning member is dropped. The dirty liquid or dirt enters the sewage bucket through the suction port under the action of the suction device of the surface cleaning device. A water supply port 41 is provided below the roller brush cover 2, and a water diversion plate 4 is arranged toward the cleaning member. The water diversion plate 4 is located above the scraper strip. The floor brush assembly also includes an arc edge 51 smoothly connected to the arc surface. The arc edge 51 extends upward along the upper end of the arc surface and covers the roller brush assembly 3. The arc edge 51 and the cleaning member have a gradually increasing gap. Specifically, the gap between the arc edge 51 and the cleaning member gradually increases along the forward rotation direction of the cleaning member.

[0053] In order to reduce the thickness of the machine body, a water tank 5 is placed in the accommodating cavity 12, and the arc edge 51 is formed by the front wall of the upper port of the water tank 5 extending upward to the front end of the roller brush cover 2. It can be understood that the water tank 5 is moved into the floor brush assembly to greatly reduce the thickness of the machine body, thereby making the machine body of the surface cleaning device equipped with the floor brush assembly thinner, which not only allows the floor brush assembly to enter a low space, but also allows the machine body to enter a relatively low area, thereby allowing the floor brush assembly to extend into a low space for dirty cleaning, thereby improving the flexibility of the surface cleaning device and improving the user's experience. At the same time, the arc edge 51 is provided on the water tank 5, so that the user can clean the arc edge 51 while cleaning the water tank 5, so as to reduce the cleaning burden of the user, and also allows the user to disassemble and assemble the water tank 5 while realizing the disassembly and assembly of the arc edge 51, so as to achieve the effect of facilitating the user to disassemble and assemble the arc edge 51, so as to further improve the user's experience.

[0054] In this embodiment, the water divider plate 4 is arranged on the housing 1 to increase the stability of the water divider plate 4, thereby ensuring the wetting effect of the water divider plate 4 on the cleaning member. The roller brush cover 2 is arranged separately from the water tank 5, that is, the roller brush cover 2 is only arranged on the top of the water tank 5 so as to clean the inside of the water tank 5.

[0055] In this embodiment, refer to Figure 2 and Figure 3 In order to prevent dirt from clogging the water supply port 41, the water diversion plate 4 includes an arc surface concentric with the roller 31, and the water supply port 41 is arranged on the arc surface. The arc surface is arranged to fit the bristles of the cleaning member, and the lower end of the arc edge 51 is smoothly connected to the upper end of the arc surface. Specifically, the inner diameter of the arc surface is less than or equal to the outer diameter of the cleaning member in a compressed state, so that when the roller 31 drives the cleaning member to rotate forward, the bristles on the cleaning member can clean the water diversion plate 4 to improve the cleanliness of the water diversion plate 4 and reduce the situation where the water supply port 41 is blocked by dirt, thereby ensuring that the water supply system supplies water to the cleaning member and the surface to be cleaned, so that the floor brush assembly works stably to ensure the cleaning effect and cleaning efficiency of the surface cleaning device, thereby further improving the user experience. At the same time, it prevents the dirt from being thrown onto the water diversion plate 4 when the cleaning member rotates, so as to ensure the cleanliness of the water diversion plate 4. The lower part of the arc edge 51 is smoothly connected to the upper end of the arc surface to avoid the situation where there is a step difference between the lower part of the arc edge 51 and the upper end of the arc surface, which is easy to hide dirt and grime, thereby further reducing the cleaning burden of the user. At the same time, the connection between the arc edge 51 and the arc surface is smoothly transitioned, so that the water tank 5 is easier to clean, thereby further improving the user's experience.

[0056] In order to reduce the cleaning difficulty and burden of the user, the center of the arc edge 51 is set not lower than the center of the roller 31, so that there is a gap between the arc edge 51 and the cleaning element in a fluffy state, and then when the bristles of the cleaning element rotate forward and pass through the water dividing plate 4, the bristles are stretched from a compressed state to a fluffy state, and the residual water and fine particles inside the bristles will be thrown onto the arc edge 51, avoiding the situation where the residual water and fine particles inside the cleaning element are thrown onto the surface to be cleaned on the front side of the floor brush assembly or the charging base of the whole machine, so as to facilitate the user to disassemble and clean, thereby further improving the user experience. At the same time, there is a gap between the arc-shaped edge 51 and the cleaning piece in the fluffy state, thereby avoiding an interference fit between the cleaning piece in the fluffy state and the arc-shaped edge, resulting in the water tank 5 being lifted upward, causing the water tank 5 to drive the floor brush assembly off the ground or causing the risk of shaking or jumping, thereby reducing the instability of the water supply of the water tank 5 and the probability of the operation and cleaning of the floor brush assembly being affected due to the instability of the water tank 5, thereby ensuring that the cleaning piece can better contact with the surface to be cleaned and wipe it clean, and reducing the problem of sewage and dirt entering the accommodating cavity 12 of the shell 1 due to a large gap between the water tank 5 and the shell 1 caused by the water tank 5 being lifted up, thereby reducing the user's cleaning burden on the shell 1.

[0057] In this embodiment, refer to Figure 3 The arc edge 51 is arranged concentrically with the roller 31, and the inner diameter of the arc edge 51 is larger than the outer diameter of the cleaning element in the fluffy state, so that there is a gap between the arc edge 51 and the cleaning element in the fluffy state to ensure the arc edge 51's collection effect on residual water and fine particles.

[0058] Reference Figure 3 In order to achieve a smooth connection between the lower part of the arc edge 51 and the upper end of the arc surface, the lower end of the arc edge 51 has a transition section 511, and the center of the transition section 511 is eccentric with the center of the arc edge 51, so that the lower part of the arc edge 51 is smoothly connected with the upper end of the arc surface.

[0059] Of course, it is understandable that the center of the arc edge 51 can also be located above the center of the roller 31, that is, the center of the arc edge 51 is eccentrically arranged with the center of the roller 31, so that the lower part of the arc edge 51 is smoothly connected to the upper end of the arc surface, thereby reducing the production difficulty of the water tank 5, thereby reducing the production cost of the water tank 5 and improving the production efficiency of the water tank 5.

[0060] Embodiment 2:

[0061] Reference Figures 4 to 6As the floor brush assembly of the present embodiment, the water dividing plate 4 is fixedly connected to the water tank 5 so that the user can clean the water dividing plate 4 while cleaning the water tank 5, avoiding the need to clean the water dividing plate 4 and the water tank 5 separately. In particular, the water dividing plate 4 is fixed on the shell 1, which is inconvenient for the user to clean the water dividing plate 4, and it is impossible to ensure that the water supply port 41 of the water dividing plate 4 is cleaned. If it is not cleaned for a long time, the surface cleaning device will have intermittent or insufficient water supply, affecting the cleaning effect and cleaning efficiency. In the present embodiment, fixing the water dividing plate 4 on the water tank 5 greatly reduces the cleaning burden of the user, so as to further improve the user's use experience. At the same time, it can further save the space in the shell 1, and there is no need to occupy a large space for the connection or coordination of the two to ensure the water storage capacity of the water tank 5. At the same time, the floor brush assembly can also be made thinner, so as to ensure that it can be extended into a lower space for cleaning.

[0062] Reference Figure 4 and Figure 6 A seal 6 is provided at the lower end of the arc surface to reduce the cleaning burden of the user, and after the water tank 5 is placed in the accommodating cavity 12, the seal 6 seals the gap between the water diversion plate 4 and the shell 1 to reduce the risk of sewage entering the shell 1 from the gap between the water diversion plate 4 and the shell 1, thereby ensuring the cleanliness of the shell 1, so as to further reduce the cleaning burden of the user, and further improve the user's usage experience.

[0063] In order to increase the sealing effect of the seal 6 on the gap between the water distribution plate 4 and the housing 1, refer to Figure 6 The sealing member 6 includes a connecting portion 61 connected to the water diversion plate 4 and a sealing portion 62 located at the bottom of the connecting portion 61. After the water tank 5 is placed in the accommodating chamber 12, the sealing portion 62 undergoes elastic deformation to increase the connection area between the sealing portion 62 and the shell 1, thereby increasing the sealing effect of the sealing portion 62 on the gap between the shell 1 and the water diversion plate 4, so as to further reduce the risk of sewage entering the shell 1, thereby further increasing the cleanliness of the shell 1; at the same time, since the connection area between the sealing member 6 and the shell 1 is increased, the connection stability between the water diversion plate 4 and the shell 1 is increased, so as to ensure the wetting effect of the water diversion plate 4 on the cleaning member, thereby ensuring the cleaning effect of the surface cleaning device equipped with the floor brush assembly in the present application.

[0064] The connecting portion 61 is a C-shaped structure, and a convex rib extending into the connecting portion 61 is provided at the bottom of the water diversion plate 4 to increase the connection area between the connecting portion 61 and the water diversion plate 4, thereby increasing the connection stability between the sealing member 6 and the water diversion plate 4 to ensure the sealing effect of the sealing member 6 on the gap between the water diversion plate 4 and the shell 1.

[0065] The sealing portion 62 is a structure that extends and bends in a direction away from the roller 31 to increase the elastic deformation effect and deformation range of the sealing portion 62, while increasing the connection area between the sealing portion 62 and the shell 1, further ensuring the sealing effect of the sealing member 6 on the gap between the water diversion plate 4 and the shell 1.

[0066] The material of the seal 6 is not limited. Preferably, the seal 6 is made of silicone or rubber material to ensure the sealing effect of the seal 6 on the gap between the water dividing plate 4 and the housing 1 .

[0067] Reference Figure 6 In order to scrape the cleaning member, the housing 1 is provided with a scraper bar 11, which is protruding from the arc surface, so that when the cleaning member rotates, the scraper bar 11 scrapes the cleaning member to increase the cleanliness of the cleaning member. At the same time, the scraper bar 11 is located at the bottom of the water diversion plate 4, and after the water tank 5 is placed in the accommodating cavity 12, the connecting portion 61 is pressed against the scraper bar 11 and undergoes elastic deformation. Since the end face of the scraper bar 11 is relatively flat, the sealing effect of the sealing member 6 on the gap between the water diversion plate 4 and the housing 1 is increased.

[0068] In order to increase the stability of the water tank 5, the end of the scraper 11 close to the roller 31 is bent downward and extended in the direction of the roller 31, so that a space for accommodating the seal 6 is formed between the end of the scraper 11 close to the roller 31 and the water diversion plate 4. That is to say, when the water tank 5 is placed in the accommodating cavity 12, the sealing portion 62 is pressed against the end of the scraper 11 close to the roller 31 and is located in the space formed between the scraper 11 and the water diversion plate 4, so that the bottom end surface of the water tank 5 is in contact with the shell 1 to increase the stability of the water tank 5.

[0069] It is understandable that the water diversion plate 4 can also be fixedly connected to the roller brush cover 2. Since the roller brush cover 2 is generally detachable, the user can clean the water diversion plate 4 while cleaning the roller brush cover 2, thereby ensuring the convenience of cleaning the water diversion plate 4, especially ensuring that the water supply hole is not blocked by dirt, thereby improving the cleaning efficiency and ensuring the cleaning effect.

[0070] The other structures of the second embodiment are the same as those of the first embodiment and will not be described in detail here.

[0071] Embodiment three:
