Description

Technical Field

[0001] The present application belongs to the technical field of cleaning appliances, and in particular relates to a surface cleaning device with good liquid uniformity effect. Background Art

[0002] Wet surface cleaning devices rotate a wetted cleaning element to wipe the surface being cleaned. The uniformity of the cleaning liquid's coverage and the degree of its wetting directly impact its effectiveness. However, the continuous rotation of the cleaning element during operation affects the uniformity of the liquid spray nozzles on the cleaning element. Furthermore, the centrifugal force of the cleaning element causes some cleaning liquid to splash outward.

[0003] To solve this technical problem, the prior art proposes to arrange a water-distributing scraper downstream of the liquid spray port, which contacts the cleaning element. The water-distributing scraper can stop the cleaning liquid ejected outward and spread the cleaning liquid on the cleaning element to a certain extent. However, this technology has the following drawbacks: on the one hand, due to the high-speed rotation of the cleaning element, the cleaning liquid is affected by the wall-adhering effect. Under the action of the liquid surface tension, it adheres to the surface of the water-distributing scraper and cannot be used to soak the cleaning element. When the cleaning liquid accumulates to a certain level, it is thrown out along with the rotation of the cleaning element. The cleaning element has poor absorption effect on the cleaning liquid, and the water-distributing scraper has poor water-blocking effect. On the other hand, because some cleaning liquid clumps together at the water-distributing scraper due to the wall-adhering effect, it is difficult for the water-distributing scraper to spread the cleaning liquid evenly, and the cleaning liquid is poorly distributed evenly on the cleaning element. Utility Model Content

[0004] The present application provides a surface cleaning device with good liquid uniformity effect, so as to solve the technical problems in existing surface cleaning devices that the cleaning liquid is easily thrown out of the cleaning parts and the cleaning liquid has poor uniformity of adhesion on the cleaning parts.

[0005] The technical solutions adopted in this application are:

[0006] A surface cleaning device with good liquid uniformity effect includes a floor brush housing and a cleaning member and a liquid spray port arranged in the floor brush housing. The cleaning member rotates to wipe the surface to be cleaned, and the liquid spray port supplies liquid to the cleaning member. The floor brush housing is also provided with a liquid blocking member and a liquid uniformity member. The liquid blocking member and the liquid uniformity member are arranged in sequence in the rotation direction of the cleaning member. The liquid blocking member extends toward the cleaning member and is separated from the cleaning member. The liquid uniformity member abuts against the cleaning member.

[0007] The surface cleaning device of the present application also includes the following additional technical features:

[0008] The liquid blocking member and the liquid uniforming member are installed on the floor brush housing through a first installation groove, and the liquid blocking member and the liquid uniforming member are arranged at an angle to form a buffer gap.

[0009] The floor brush housing is provided with a second mounting groove for installing the liquid blocking member and a third mounting groove for installing the liquid leveling member on the side facing the cleaning member. The second mounting groove and the third mounting groove are arranged at intervals to form a buffer gap between the liquid blocking member and the liquid leveling member.

[0010] The length of the buffer gap is D, 1.5 mm ≤ D ≤ 3 mm.

[0011] The liquid blocking member and the liquid distributing member extend obliquely toward the direction where the cleaning member is located.

[0012] The floor brush housing further comprises a cover, the liquid blocking member and the liquid leveling member are both provided on the cover, the angle between the liquid leveling member and the cleaning member is α, 40°≤α≤60°. The liquid leveling member has an arc section on the side facing the cleaning member for guiding liquid droplets to flow toward the cleaning member.

[0013] The liquid leveling member is an elastic structure extending axially parallel to the cleaning member. The liquid leveling member includes a connecting portion connected to the floor brush housing and an abutting portion abutting the cleaning member. The thickness of the connecting portion is smaller than that of the abutting portion.

[0014] The cleaning member is an annular mop, which includes two arc-shaped portions and a straight portion located between the two arc-shaped portions, and the liquid-distributing member abuts against the straight portion.

[0015] The cleaning member is a cylindrical roller brush, and the liquid uniformizing member is arranged above the central axis of the roller brush.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. The surface cleaning device of the present application is equipped with a liquid barrier and a liquid distribution member arranged in sequence along the direction of rotation of the cleaning element on the floor brush housing. A portion of the cleaning liquid sprayed from the liquid spray port adheres to the surface of the cleaning element, while a portion splashes forward. The liquid barrier, located downstream of the liquid spray port, intercepts the splashing liquid, reducing the possibility of the liquid not wetting the cleaning element and directly falling onto the surface to be cleaned. Cleaning liquid at a certain speed is broken up into multiple smaller clumps of cleaning liquid upon impact with the liquid barrier. Due to the small size of these clumps, they can more easily adhere to the surface of the cleaning element as they move toward the cleaning element under their own gravity, rather than adhering to the wall of the liquid barrier. The liquid barrier is separated from the cleaning element. This, on the one hand, does not create resistance to the cleaning element during rotation, allowing the cleaning element to rotate at a higher speed and wipe the surface to be cleaned, ensuring cleaning power. On the other hand, the separation of the liquid barrier from the cleaning element allows liquid flowing along the wall of the liquid barrier to escape along the edge of the liquid barrier and then freely fall.

[0018] Furthermore, a liquid leveling member that abuts the cleaning member is provided downstream of the liquid blocking member. On the one hand, the liquid blocking member is separately provided from the cleaning member, so that the liquid flowing along the wall of the liquid blocking member continues to move after escaping along the edge of the liquid blocking member, and part of the liquid still has a tendency to move forward. The liquid leveling member provided downstream of the liquid blocking member intercepts part of the liquid and guides it to infiltrate the cleaning member. On the other hand, the liquid leveling member abutting the cleaning member can guide the liquid on the surface of the cleaning member to diffuse along the extension direction of the liquid leveling member, and diffuse along the rotation direction of the cleaning member as the liquid leveling member scrapes the cleaning member, thereby achieving multi-directional diffusion of the cleaning liquid along the rotation direction of the cleaning member and the extension direction of the liquid leveling member, so that the cleaning liquid can be more evenly dispersed to various areas of the cleaning member, thereby improving the uniformity of coverage of the cleaning liquid on the outer surface of the cleaning member, thereby enabling the cleaning liquid to fully and evenly infiltrate the outer surface of the cleaning member, achieving uniform cleaning of the surface to be cleaned by the cleaning member, and further improving the cleaning effect of the surface cleaning device.

[0019] 2. As a preferred embodiment of the present application, the liquid blocking member and the liquid uniformizing member are installed simultaneously on the floor brush housing through the first installation groove, which can reduce the number of slots on the floor brush housing, reduce the difficulty of processing and manufacturing the floor brush housing, and help improve the structural strength of the floor brush housing; in addition, the liquid uniformizing member and the liquid blocking member are arranged at an angle to form a buffer gap, which provides a certain buffer space for the cleaning liquid dispersed by the liquid blocking member, and provides sufficient space for the cleaning liquid dispersed by the liquid blocking member. The cleaning liquid that has freely diffused for a period of time in the buffer gap is more dispersed and uniform than when it just drips from the liquid blocking member to the cleaning member, reducing the possibility of the cleaning liquid gathering into clumps on the liquid uniformizing member. After the cleaning liquid has freely diffused for a period of time in the buffer gap and then passes through the liquid uniformizing member, it is further uniformed by the liquid uniformizing member so that the cleaning liquid is more evenly distributed on the cleaning member.

[0020] 3. As a preferred embodiment of the present application, by providing a second mounting groove and a third mounting groove, installation space is provided for the liquid blocking member and the liquid homogenizing member, respectively. The setting of the buffer gap provides a certain buffer space for the cleaning liquid dispersed by the liquid blocking member, providing sufficient space for the cleaning liquid dispersed by the liquid blocking member to move to the cleaning member and be absorbed by the cleaning member. The cleaning liquid falling on the cleaning member is freely diffused in the buffer space. On the one hand, it makes the infiltration of the cleaning member more uniform. On the other hand, the cleaning liquid is dispersed during the free diffusion process, which reduces the possibility of the cleaning liquid gathering into clumps on the liquid homogenizing member, thereby enhancing the infiltration effect of the cleaning liquid on the cleaning member. In addition, the liquid blocking member and the liquid homogenizing member are respectively installed on the floor brush housing through the second mounting groove and the third mounting groove. The length of the buffer gap can be adjusted by changing the relative position of the second mounting groove and the third mounting groove, thereby adjusting the diffusivity of the cleaning liquid moving between the liquid blocking member and the liquid homogenizing member. The liquid blocking member and the liquid homogenizing member respectively installed in the second mounting groove and the third mounting groove can be disassembled or replaced separately, making maintenance and cleaning more convenient.

[0021] 4. As a preferred embodiment of the present application, the length of the buffer gap D is set to 1.5mm≤D≤3mm. The length D is between 1.5mm and 3mm and includes the endpoint values of 1.5mm and 3mm. This range can ensure that the cleaning liquid has sufficient movement space to achieve contact with the cleaning parts and infiltrate the cleaning parts, and satisfy the cleaning liquid to fully diffuse and move between the liquid blocking parts and the liquid uniforming parts, so that the cleaning liquid contacts the liquid uniforming parts after sufficient diffusion. At the same time, it can avoid the cleaning liquid droplets from contacting each other and converging into larger liquid masses due to irregular movement caused by the cleaning liquid moving for too long. In addition, the structural layout of the floor brush housing can be optimized to reserve more installation space for the remaining components of the floor brush housing, which is conducive to the miniaturization of the floor brush housing.

[0022] 5. As a preferred embodiment of the present application, the liquid blocking member and the liquid leveling member are configured to extend obliquely toward the cleaning member. The obliquely extended liquid blocking member reduces the resistance encountered by splashing cleaning liquid when it strikes the liquid blocking member, allowing the cleaning liquid to disperse more along the outer surface of the liquid blocking member after impact, forming a wider flow area. Furthermore, due to the influence of the inclination angle of the liquid blocking member, the cleaning liquid dispersed by the impact will flow more toward the extension direction of the liquid blocking member. That is, after impacting the liquid blocking member, the cleaning liquid will flow toward the cleaning member under the guidance of the liquid blocking member, thereby enhancing the wetting effect of the cleaning liquid on the cleaning member. The liquid leveling member is configured to be inclined. On the one hand, the cleaning liquid that collides with the liquid leveling member is better dispersed on the outer surface of the liquid leveling member due to the influence of the impact angle. Furthermore, due to the influence of the inclination angle of the liquid leveling member, the cleaning liquid moves along the extension direction of the liquid leveling member toward the cleaning member, further increasing the cleaning member's absorption of the cleaning liquid and the uniformity of the distribution of the cleaning liquid on the outer surface of the cleaning member. On the other hand, the friction between the liquid leveling member and the cleaning member is reduced, which facilitates the rotation of the cleaning member.

[0023] Furthermore, the angle α between the liquid-leveling member and the cleaning member is set to 40°≤α≤60°, and the size of the angle α is between 40° and 60° and includes the endpoint values of 40° and 60°. This range can not only satisfy the requirement that the cleaning liquid is subjected to sufficient impact force when it contacts the liquid-leveling member and is dispersed, thereby improving the diffusion uniformity of the cleaning liquid and thus improving the cleaning efficiency of the cleaning member; at the same time, the liquid-leveling member can provide a good guiding effect for the cleaning liquid, and under the guidance of the liquid-leveling member, the cleaning liquid attached to the liquid-leveling member can move relatively smoothly toward the cleaning member. It is thereby adsorbed on the surface of the cleaning part, further increasing the degree of wetting of the cleaning liquid on the cleaning part, and improving the cleaning effect of the surface cleaning device; in addition, the liquid-uniform part within the angle range can provide the cleaning liquid adsorbed on the outer surface of the liquid-uniform part under the action of wall adhesion with an adsorption force at a suitable angle to the gravity of the cleaning liquid, so that the cleaning liquid can move more smoothly toward the cleaning part under the combined action of the adsorption force and gravity, that is, the gravity of the cleaning liquid has a certain degree of offsetting effect on the adsorption force adsorbed on the liquid-uniform part, thereby reducing the possibility of the cleaning liquid adhering to the wall.

[0024] Furthermore, by providing an arc segment on the liquid uniforming part, on the one hand, when the cleaning liquid comes into contact and collides with the arc segment, the cleaning liquid will slide along the arc segment under the influence of the surface geometry of the arc segment, and the curvature of the arc segment will change the internal fluid dynamics of the cleaning liquid, promote the dispersion of the cleaning liquid, and enable the cleaning liquid to be fully spread on the arc segment, thereby increasing the contact area between the cleaning liquid and the cleaning part; on the other hand, the provision of the arc segment causes the flow direction of the cleaning liquid to continuously change during the movement along the outer surface of the liquid uniforming part, thereby weakening the wall-adhering effect of the cleaning liquid, and the cleaning liquid can more easily move along the outer surface of the liquid uniforming part toward the cleaning part under the action of its own gravity or directly drip onto the outer surface of the cleaning part under the action of its own gravity, thereby avoiding the accumulation of the cleaning liquid at the abutment portion between the liquid uniforming part and the cleaning part, thereby reducing the possibility of the cleaning liquid splashing due to the rotation of the cleaning part.

[0025] 6. As a preferred embodiment of the present application, the liquid-leveling member is set as an elastic structure, so that the liquid-leveling member can adjust the friction between itself and the cleaning member through its own elastic deformation, thereby reducing the wear on the cleaning member while ensuring that the cleaning liquid on the cleaning member is evenly spread, which helps to increase the service life of the cleaning member and the liquid-leveling member; in addition, the thickness of the connecting portion is set to be smaller than the thickness of the abutting portion, which increases the contact area between the cleaning member and the liquid-leveling member, and helps to increase the liquid-leveling ability of the liquid-leveling member. At the same time, the thickness of the connecting portion is smaller than that of the abutting portion, so that the connecting portion can more easily undergo elastic deformation under the reaction force of the cleaning member, thereby adjusting The angle between the liquid-uniform part and the floor brush shell is adjusted, and then the friction force on the cleaning part is adjusted; at the same time, for some cleaning parts with flannel or other fragile materials on the outer surface, the continuous wear of the flannel or other materials will cause the surface area of the cleaning part to continue to decrease with the use of the cleaning part, thereby reducing the force of the cleaning part on the liquid-uniform part. The liquid-uniform part will adjust the angle between it and the floor brush shell as the force of the cleaning part decreases, so that the friction force of the liquid-uniform part on the cleaning part is always within an appropriate range, avoiding excessive friction on the cleaning part, and making adaptive elastic deformation as the surface area of the cleaning part changes to exert appropriate friction on the cleaning part.

[0026] 7. As a preferred embodiment of the present application, the cleaning member is set as a ring-shaped mop, which increases the surface area of the cleaning member and helps to improve the cleaning efficiency of the cleaning member on the surface to be cleaned, and the liquid uniformizing member is abutted against the straight portion, so that the cleaning liquid can be more evenly distributed on the outer surface of the cleaning member under the action of the liquid uniformizing member before entering the arc portion as the cleaning member rotates, thereby reducing the possibility of accumulation of the cleaning liquid in the arc portion. Therefore, the cleaning liquid that moves to the arc portion is not easily thrown out of the cleaning member under the action of the centrifugal force brought about by the rotation of the arc portion, which helps to improve the cleaning efficiency of the surface cleaning device; in addition, the abutment of the liquid uniformizing member with the straight portion helps to reduce the friction between the liquid uniformizing member and the cleaning member, reduce the wear of the liquid uniformizing member on the cleaning member, and thus help to improve the service life of the cleaning member.

[0054] Example 1:

[0055] like Figures 1 to 3 、 Figure 6 、 Figure 7 As shown, a surface cleaning device with good liquid uniformity effect includes a floor brush housing 3 and a cleaning member 1 and a liquid spray port 2 arranged in the floor brush housing 3. The cleaning member 1 rotates to wipe the surface to be cleaned, and the liquid spray port 2 supplies liquid to the cleaning member 1. The floor brush housing 3 is also provided with a liquid blocking member 4 and a liquid uniformity member 5. The liquid blocking member 4 and the liquid uniformity member 5 are arranged in sequence in the rotation direction of the cleaning member 1. The liquid blocking member 4 extends toward the cleaning member 1 and is separated from the cleaning member 1. The liquid uniformity member 5 abuts against the cleaning member 1.

[0056] The surface cleaning device of the present application is equipped with a liquid barrier 4 and a liquid leveling member 5, arranged sequentially along the rotational direction of the cleaning member 1, on the floor brush housing 3. A portion of the cleaning liquid ejected from the liquid spray port 2 adheres to the surface of the cleaning member 1, while a portion splashes forward. The liquid barrier 4, located downstream of the liquid spray port 2, intercepts the splashing liquid, reducing the likelihood of the liquid falling directly onto the surface to be cleaned without wetting the cleaning member 1. Cleaning liquid at a certain velocity is broken up into multiple smaller clumps upon impact with the liquid barrier 4. Due to their small size, these clumps more easily adhere to the surface of the cleaning member 1 as they move toward the cleaning member 1 under their own gravity, rather than adhering to the walls of the liquid barrier 4. The liquid barrier 4 is separated from the cleaning member 1. This, on the one hand, does not create resistance to the cleaning member 1 during its rotation, allowing it to rotate at a higher speed and maintain cleaning power while wiping the surface to be cleaned. On the other hand, the separation of the liquid barrier 4 from the cleaning member 1 allows liquid flowing along the walls of the liquid barrier 4 to escape along its edges and then freely fall.

[0057] Furthermore, a liquid leveling member 5 is provided downstream of the liquid blocking member 4 and abuts against the cleaning member 1. On the one hand, the liquid blocking member 4 is provided separately from the cleaning member 1, so that the liquid flowing along the wall of the liquid blocking member 4 continues to move after escaping along the edge of the liquid blocking member 4, and part of the liquid still has a tendency to move forward. The liquid leveling member 5 provided downstream of the liquid blocking member 4 intercepts part of the liquid and guides it to infiltrate the cleaning member 1. On the other hand, the liquid leveling member 5 abutting against the cleaning member 1 can guide the liquid on the surface of the cleaning member 1 to diffuse along the extension direction of the liquid leveling member 5, and as the liquid leveling member 5 scrapes the cleaning member 1, it diffuses along the rotation direction of the cleaning member 1, achieving multi-directional diffusion of the cleaning liquid along the rotation direction of the cleaning member 1 and the extension direction of the liquid leveling member 5, so that the cleaning liquid can be more evenly dispersed to various areas of the cleaning member 1, thereby improving the uniformity of the coverage of the cleaning liquid on the outer surface of the cleaning member 1, so that the cleaning liquid can fully and evenly infiltrate the outer surface of the cleaning member 1, achieving the uniformity of the cleaning of the surface to be cleaned by the cleaning member 1, and further improving the cleaning effect of the surface cleaning device.

[0058] This embodiment 1 does not limit the type of cleaning liquid, which can be adaptively adjusted according to the cleaning requirements of the surface to be cleaned. For example, the cleaning liquid can be water, disinfectant, acidic detergent, alkaline detergent, neutral detergent, etc.

[0059] As a preferred implementation scheme under this embodiment 1, an installation cavity for installing the cleaning part 1 is provided in the floor brush housing 3, and the liquid blocking part 4 and the liquid uniformizing part 5 are both strip-shaped structures and extend along the length direction of the cleaning part 1. The length of the liquid blocking part 4 and the liquid uniformizing part 5 is close to the length of the cleaning part 1.

[0060] As a preferred implementation of this embodiment 1, Figures 2 to 4As shown, the liquid blocking member 4 and the liquid leveling member 5 are installed on the floor brush housing 3 through the first installation groove 6 , and the liquid blocking member 4 and the liquid leveling member 5 are arranged at an angle to form a buffer gap 9 .

[0061] Synchronously installing the liquid blocking member 4 and the liquid uniformizing member 5 on the floor brush housing 3 through the first mounting groove 6 can reduce the number of slots on the floor brush housing 3, reduce the difficulty of processing and manufacturing the floor brush housing 3, and help improve the structural strength of the floor brush housing 3; in addition, the liquid uniformizing member 5 and the liquid blocking member 4 are arranged at an angle to form a buffer gap 9, which provides a certain buffer space for the cleaning liquid dispersed by the liquid blocking member 4. The cleaning liquid that has freely diffused for a period of time in the buffer gap 9 is more dispersed and uniform than when it just drips from the liquid blocking member 4 onto the cleaning member 1, reducing the possibility of the cleaning liquid gathering into clumps on the liquid uniformizing member 5. After the cleaning liquid has freely diffused for a period of time in the buffer gap 9 and then passes through the liquid uniformizing member 5, it is homogenized again by the liquid uniformizing member 5 to make the cleaning liquid more evenly distributed on the cleaning member 1.

[0062] Preferably, the angle β between the liquid blocking member 4 and the liquid leveling member 5 satisfies 15°≤β≤25°. The angle β includes any value between 15° and 25° and an endpoint value between 15° and 25°.

[0063] As a preferred embodiment of this embodiment, the liquid blocking member 4 and the liquid leveling member 5 are integrally formed, and a mounting block 10 is provided at the connection between the two. The mounting block 10 is interference-fitted with the first mounting groove 6. Providing the liquid blocking member 4 and the liquid leveling member 5 as an integrally formed unit helps to reduce the difficulty of assembling the liquid blocking member 4 and the liquid leveling member 5. By installing the mounting block 10 in the first mounting groove 6, the liquid blocking member 4 and the liquid leveling member 5 can be installed simultaneously, thereby improving the assembly efficiency of the surface cleaning device.

[0064] As a preferred implementation method of this embodiment 1, Figure 2 、 Figure 3 、 Figure 6 、 Figure 7As shown, the liquid blocking member 4 and the liquid leveling member 5 extend obliquely toward the direction of the cleaning member 1. The oblique extension of the liquid blocking member 4 reduces the resistance encountered by the splashing cleaning liquid when it strikes the liquid blocking member 4. This allows the cleaning liquid to disperse more along the outer surface of the liquid blocking member 4 after impact, forming a wider flow area. Furthermore, due to the inclination angle of the liquid blocking member 4, the cleaning liquid dispersed by the impact will flow more in the direction of the extension of the liquid blocking member 4. That is, after impacting the liquid blocking member 4, the cleaning liquid will flow toward the cleaning member 1 under the guidance of the liquid blocking member 4, thereby improving the wetting effect of the cleaning liquid on the cleaning member 1. The liquid leveling member 5 is arranged at an angle. On the one hand, the cleaning liquid that collides with the liquid leveling member 5 is better dispersed on the outer surface of the liquid leveling member 5 due to the impact angle. On the other hand, due to the inclination angle of the liquid leveling member 5, the cleaning liquid moves along the extension direction of the liquid leveling member 5 toward the cleaning member 1, further increasing the cleaning member 1's absorption capacity for the cleaning liquid and the uniformity of the distribution of the cleaning liquid on the outer surface of the cleaning member 1. On the other hand, reducing the friction between the liquid leveling member 5 and the cleaning member 1 is beneficial to the rotation of the cleaning member 1. The cleaning member 1 absorbs the cleaning liquid and distributes the cleaning liquid uniformly on the outer surface of the cleaning member 1.

[0065] It should be noted that the inclined extension direction of the liquid blocking member 4 and the liquid leveling member 5 in this embodiment refers to the inclination toward the downstream side of the rotation direction of the cleaning member 1. Figure 3 、 Figure 7 Schematically depicting the rotation direction of the cleaning member 1 , the arrow X indicates the rotation direction of the cleaning member 1 , and the liquid blocking member 4 and the liquid leveling member 5 are inclined toward the rear side of the arrow X.

[0066] As a preferred embodiment of this embodiment, Figure 3 、 Figure 5As shown, the floor brush housing 1 also includes a cover 31, and the liquid blocking member 4 and the liquid uniforming member 5 are both provided on the cover 31. The angle between the liquid uniforming member 5 and the cleaning member 1 is α, 40°≤α≤60°. The angle α between the liquid uniforming member 5 and the cleaning member 1 is set to 40°≤α≤60°, and the size of the angle α is between 40° and 60° and includes the endpoint values of 40° and 60°. This range can satisfy that the cleaning liquid is dispersed by sufficient impact force when it contacts the liquid uniforming member 5, thereby improving the diffusion uniformity of the cleaning liquid and increasing the cleaning efficiency of the cleaning liquid; at the same time, the liquid uniforming member 5 can provide a good guiding effect for the cleaning liquid. Under the guidance of the liquid uniforming member 5, the cleaning liquid attached to the liquid uniforming member 5 can move relatively smoothly toward the cleaning member 1, thereby It is adsorbed on the surface of the cleaning member 1, further improving the degree of wetting of the cleaning liquid on the cleaning member 1 and improving the cleaning effect of the surface cleaning device; in addition, the liquid-uniform member 5 within the angle range can provide the cleaning liquid adsorbed on the outer surface of the liquid-uniform member 5 under the action of wall adhesion with an adsorption force that is at a suitable angle to the gravity of the cleaning liquid, so that the cleaning liquid can move more smoothly toward the cleaning member 1 under the combined action of the adsorption force and gravity, that is, the gravity of the cleaning liquid has a certain degree of offsetting effect on the adsorption force adsorbed on the liquid-uniform member 5, thereby reducing the possibility of the cleaning liquid adhering to the wall.

[0067] As another preferred embodiment under this embodiment, Figure 3 、 Figure 7 、 Figure 9 As shown, the liquid leveling member 5 has an arc segment 51 on the side facing the cleaning member 1 for guiding the liquid droplets to flow toward the cleaning member 1 . By providing an arc segment 51 on the liquid uniforming member 5, on the one hand, when the cleaning liquid contacts and collides with the arc segment 51, the cleaning liquid will slide along the arc segment 51 under the influence of the surface geometry of the arc segment 51, and the curvature of the arc segment 51 will change the internal fluid dynamics of the cleaning liquid, promote the dispersion of the cleaning liquid, and enable the cleaning liquid to be fully spread on the arc segment 51, thereby increasing the contact area between the cleaning liquid and the cleaning member 1; on the other hand, the provision of the arc segment 51 causes the flow direction of the cleaning liquid to continuously change during the movement along the outer surface of the liquid uniforming member 5, thereby weakening the wall-adhering effect of the cleaning liquid, and the cleaning liquid can more easily move along the outer surface of the liquid uniforming member 5 toward the cleaning member 1 under the action of its own gravity, or directly drip onto the outer surface of the cleaning member 1 under the action of its own gravity, thereby avoiding the cleaning liquid from accumulating at the abutment portion 53 between the liquid uniforming member 5 and the cleaning member 1, thereby reducing the possibility of the cleaning liquid being splashed due to the rotation of the cleaning member 1.

[0068] As a preferred example under this embodiment, Figure 9As shown, the curvature of the arc segment 51 gradually increases from the end away from the cleaning member 1 to the end closer to the cleaning member 1. Setting the curvature of the arc segment 51 to gradually increase causes the internal fluid dynamics of the cleaning liquid attached to the arc segment 51 to change direction more irregularly. The cleaning liquid can more easily escape from the arc segment 51 and drip onto the surface of the cleaning member 1, further weakening the wall adhesion effect of the cleaning member 1, significantly reducing the accumulation of cleaning liquid at the abutment portion 53 between the liquid leveling member 5 and the cleaning member 1, and further reducing the possibility of cleaning liquid splashing due to the rotation of the cleaning member 1.

[0069] In this embodiment 1, the extension direction of the liquid blocking member 4 and the liquid leveling member 5 is not limited. In another embodiment, the liquid blocking member 4 and the liquid leveling member 5 extend downward in the vertical direction and are arranged at intervals. That is, the liquid blocking member 4 and the liquid leveling member 5 are both perpendicular to the cleaning member 1.

[0070] As a preferred implementation method of this embodiment 1, Figure 3 、 Figure 7 、 Figure 9 As shown, the liquid uniformizing member 5 is an elastic structure extending axially parallel to the cleaning member 1. The liquid uniformizing member 5 includes a connecting portion 52 connected to the floor brush housing 3 and an abutting portion 53 abutting the cleaning member 1. The thickness of the connecting portion 52 is less than the thickness of the abutting portion 53.

[0071] The liquid-leveling member 5 is set to an elastic structure, so that the liquid-leveling member 5 can adjust the friction between itself and the cleaning member 1 through its own elastic deformation, thereby reducing the wear of the cleaning member 1 under the premise of ensuring that the cleaning liquid on the cleaning member 1 is evenly spread, which helps to increase the service life of the cleaning member 1 and the liquid-leveling member 5; in addition, the thickness of the connecting portion 52 is set to be smaller than the thickness of the abutting portion 53, which increases the contact area between the cleaning member 1 and the liquid-leveling member 5, and helps to increase the liquid-leveling ability of the liquid-leveling member 5. At the same time, the thickness of the connecting portion 52 is smaller than that of the abutting portion 53, so that the connecting portion 52 can more easily undergo elastic deformation under the reaction force of the cleaning member 1, thereby adjusting the connection with the floor brush shell The angle between the body 3 and the floor brush shell 3 is adjusted, and then the friction force on the cleaning member 1 is adjusted; at the same time, for some cleaning members 1 with an outer surface made of flannel or other fragile materials, the continuous wear of the flannel or other materials will cause the surface area of the cleaning member 1 to continue to decrease with the use of the cleaning member 1, thereby reducing the force of the cleaning member 1 on the liquid uniformizing member 5. The liquid uniformizing member 5 will adjust the angle between it and the floor brush shell 3 as the force of the cleaning member 1 decreases, so that the friction force of the liquid uniformizing member 5 on the cleaning member 1 is always within an appropriate range, avoiding excessive friction on the cleaning member 1 while making adaptive elastic deformation as the surface area of the cleaning member 1 changes to apply appropriate friction to the cleaning member 1.

[0072] Preferably, the liquid-distributing member 5 can be made of rubber material.

[0073] This embodiment 1 does not limit the manufacturing material and structural form of the liquid uniforming member 5. In another embodiment, the liquid uniforming member 5 is made of a plastic material, such as plastic.

[0074] As a preferred implementation method of this embodiment 1, Figure 2 、 Figure 6 As shown, the cleaning member 1 is an annular mop, which includes two arc-shaped portions 11 and a straight portion 12 located between the two arc-shaped portions 11 , and the liquid-distributing member 5 abuts against the straight portion 12 .

[0075] The cleaning member 1 is configured as a ring-shaped mop, which increases the surface area of the cleaning member 1 and helps to improve the cleaning efficiency of the cleaning member 1 on the surface to be cleaned. The liquid uniformizing member 5 is abutted against the straight portion 12, so that the cleaning liquid can be more evenly distributed on the outer surface of the cleaning member 1 under the action of the liquid uniformizing member 5 before entering the arc portion 11 as the cleaning member 1 rotates, thereby reducing the possibility of accumulation of the cleaning liquid in the arc portion 11. Therefore, the cleaning liquid moving to the arc portion 11 is not easily thrown out of the cleaning member 1 under the centrifugal force brought about by the rotation of the arc portion 11, which helps to improve the cleaning efficiency of the surface cleaning device; in addition, the abutment between the liquid uniformizing member 5 and the straight portion 12 helps to reduce the friction between the liquid uniformizing member 5 and the cleaning member 1, reduce the wear of the liquid uniformizing member 5 on the cleaning member 1, and thus help to improve the service life of the cleaning member 1.

[0076] Example 2:

[0077] The structure and principle of this embodiment 2 are basically the same as those of embodiment 1, with the only difference being:

[0078] like Figures 6 to 8 As shown, the floor brush housing 3 is provided with a second mounting groove 7 for installing the liquid blocking part 4 and a third mounting groove 8 for installing the liquid uniformizing part 5 on the side facing the cleaning part 1. The second mounting groove 7 and the third mounting groove 8 are arranged at intervals to form a buffer gap 9 between the liquid blocking part 4 and the liquid uniformizing part 5.

[0079] By setting the second mounting groove 7 and the third mounting groove 8, installation space is provided for the liquid blocking part 4 and the liquid uniformizing part 5 respectively, and the setting of the buffer gap 9 provides a certain buffer space for the cleaning liquid dispersed by the liquid blocking part 4, and provides sufficient space for the cleaning liquid dispersed by the liquid blocking part 4 to move to the cleaning part 1 and be absorbed by the cleaning part 1. The cleaning liquid falling on the cleaning part 1 is freely diffused in the buffer space, which on the one hand makes the infiltration of the cleaning part 1 more uniform, and on the other hand, the cleaning liquid is dispersed during the free diffusion process, further reducing the possibility of the cleaning liquid gathering into clumps on the liquid uniformizing part 5, thereby enhancing the infiltration effect of the cleaning liquid on the cleaning part 1; in addition, the liquid blocking part 4 and the liquid uniformizing part 5 are respectively installed on the floor brush housing 3 through the second mounting groove 7 and the third mounting groove 8, and the length of the buffer gap 9 can be adjusted by changing the relative position of the second mounting groove 7 and the third mounting groove 8, thereby adjusting the diffusivity of the cleaning liquid moving between the liquid blocking part 4 and the liquid uniformizing part 5. The liquid blocking member 4 and the liquid leveling member 5 respectively installed in the second installation groove 7 and the third installation groove 8 can be disassembled or replaced separately, making maintenance and cleaning more convenient.

[0080] Preferably, the liquid blocking member 4 is interference fit with the second installation groove 7 , and the liquid leveling member 5 is interference fit with the third installation groove 8 .

[0081] Preferably, if Figure 3 、 Figure 7 As shown, the length of the buffer gap 9 is D, 1.5mm≤D≤3mm. It should be pointed out that D mentioned here refers to the distance between the end of the liquid blocking member 4 close to the cleaning member 1 and the position where the end is projected toward the liquid homogenizing member 5. The length of the buffer gap 9D is set to 1.5mm≤D≤3mm. The size of the length D is between 1.5mm and 3mm and includes the endpoint values of 1.5mm and 3mm. This range can not only ensure that the cleaning liquid has enough movement space to achieve contact with the cleaning member 1 and infiltrate the cleaning member 1, but also meet the cleaning liquid. The full diffusion movement between the liquid blocking member 4 and the liquid homogenizing member 5 allows the cleaning liquid to be more dispersed after sufficient diffusion and contact the liquid homogenizing member 5 respectively. At the same time, it can avoid the cleaning liquid droplets caused by the cleaning liquid moving for too long to contact each other under the action of irregular movement and converge into a larger liquid mass. In addition, the structural layout of the floor brush housing 3 can also be optimized to reserve more installation space for the remaining components of the floor brush housing 3, which is conducive to the miniaturization of the floor brush housing 3.

[0082] Example 3:

[0083] The structure and principle of this embodiment 3 are basically the same as those of embodiment 1, with the only difference being:

[0084] like Figure 10As shown, the cleaning member 1 is a cylindrical roller brush, and the liquid-distributing member 5 is arranged above the central axis of the roller brush. The liquid-distributing member 5 is arranged above the central axis of the roller brush so that the cleaning liquid can be more evenly distributed on the outer surface of the cleaning member 1 under the action of the liquid-distributing member 5 before entering the curved section of the roller brush as the roller brush rotates, thereby reducing the possibility of accumulation of the cleaning liquid in the curved section of the roller brush. Therefore, the cleaning liquid moving to the curved section of the roller brush is not easily thrown out of the cleaning member 1 under the centrifugal force generated by the rotation of the curved section of the roller brush, which helps to improve the cleaning efficiency of the surface cleaning device; in addition, being arranged above the central axis of the roller brush helps to reduce the friction between the liquid-distributing member 5 and the cleaning member 1, reducing the wear of the cleaning member 1 by the liquid-distributing member 5, thereby helping to improve the service life of the cleaning member 1.

[0085] Preferably, if Figure 3 、 Figure 7 As shown, the interference fit between the liquid leveling member 5 and the cleaning member 1 is D2, 1mm≤D2≤2mm. The overlap depth D2 is between 1mm and 2mm, including the endpoints of 1mm and 2mm. This range satisfies the requirement that the liquid leveling member 5 sufficiently spreads the cleaning liquid on the cleaning member 1, allowing the cleaning liquid to be relatively evenly distributed on the outer surface of the cleaning member 1. It also controls the friction force of the liquid leveling member 5 on the cleaning member 1 within a certain range, avoiding excessive friction between the liquid leveling member 5 and the cleaning member 1, and ensuring the service life of the liquid leveling member 5 and the cleaning member 1.
