Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning device. Background Technology

[0002] Cleaning equipment is a device capable of automatically cleaning surfaces and is widely used in people's daily lives and work. For example, cleaning equipment can include floor scrubbers. Cleaning equipment uses cleaning components to clean the surface, and during the cleaning process, the cleaning components may leave water residue on the surface.

[0003] In related technologies, to remove residual water stains, a scraper is usually installed on the front side of the cleaning device so that when the user pulls the cleaning device backward, the water stains on the surface to be cleaned are scraped and collected towards the cleaning device.

[0004] However, when the robotic arm pulls back and turns, its movement trajectory is arc-shaped, and conventional scrapers do not adequately cover the turning edge area, easily leaving water stains. Furthermore, the existing structure has limited adaptability to changes in motion, affecting the overall cleaning effect. Therefore, how to reduce water stain residue when the cleaning equipment pulls back and turns, and improve the integrity and effectiveness of the cleaning operation, has become a technical problem that needs to be solved. Summary of the Invention

[0005] This application provides a cleaning device that can effectively reduce water residue when the cleaning device is pulled back and turned, thereby improving the integrity and cleaning effect of the cleaning operation.

[0006] This application provides a cleaning device, including a body and a floor brush assembly movably disposed at the bottom of the body; the floor brush assembly includes: a mounting base; a cleaning component rotatably disposed on the front side of the mounting base, the cleaning component being used to clean the surface to be cleaned when rotating; a front wiping component disposed on the front side of the cleaning component, the front wiping component including a first wiping section and a second wiping section; wherein, the first wiping section extends along the axial direction of the cleaning component; two second wiping sections are respectively located at both ends of the first wiping section and extend laterally toward the cleaning component; the bottom of the second wiping sections is inclined toward the inner side of the floor brush assembly.

[0007] The cleaning device in this application embodiment can achieve a lateral water-gathering effect when driving straight, and a guiding water-wiping effect when turning, by setting the bottom of the second wiping section to be tilted towards the inside of the floor brush assembly.

[0008] It should be understood that the effects of tilting inward and tilting outward are not the same. Through in-depth research, it has been found that when tilting outward, if the user turns to one side, such as to the right, the left wiper section will collect the internal wastewater and bring it to the roller brush, thus clearing the wastewater on the left side. However, the right wiper end will push the wastewater on the right side, resulting in more wastewater on the right side.

[0009] However, when tilting inwards, the left-side wiper section can still remove the water when turning to the right, but because the right-side wiper section bends inwards, it will not push the sewage on the right side or spread it out, resulting in more sewage accumulating on the right side.

[0010] Specifically, when driving in a straight line, the inward-sloping second wiper section forms a shielding structure on the side. When the cleaning component rotates and splashes water to the side, the second wiper section can shield these water stains and guide them inward, concentrating them on the cleaning area of ​​the cleaning component, where they are absorbed or carried away by the cleaning component, effectively reducing water marks left on both sides of the surface to be cleaned after cleaning.

[0011] When the cleaning device turns, the floor brush assembly turns along with the device, and water splashed laterally by the cleaning components tends to escape outwards due to centrifugal force. By setting the second wiping section to be tilted inwards, with its bottom edge closer to the side edge of the cleaning components, a narrowing inward-facing guide channel is formed. During the turn, the outward-moving water is intercepted by the second wiping section and guided back to the cleaning area of ​​the cleaning components, thereby reducing the lateral outward flow of water along the turning path. Furthermore, the lateral wiping of the second wiping section reduces the arc-shaped water streaks left on the outer side of the cleaning path after the turn.

[0012] Furthermore, the inward-sloping second wiper section offers the advantage of bidirectional water collection during turns. Specifically, both the second wiper section located on the inside and outside of the turn can swipe water inwards. Compared to setting the second wiper section to slope outwards, the second wiper section on the outside of the turn pushes water outwards, creating more noticeable watermarks on the outer side of the turning path. In this design, regardless of whether the brush assembly turns left or right, the slope of the second wiper section on the outside of the turn faces inwards, effectively concentrating water towards the cleaning area.

[0013] In one possible implementation, the second wiper section is elastic; the front wiper has a working position in which both the first and second wiper sections abut against the surface to be cleaned; in the working position, the bottom of the second wiper section elastically bends 3-5mm toward the inside of the floor brush assembly under the pressure of the surface to be cleaned.

[0014] This design allows the second wiper section to undergo controlled elastic deformation upon contact with the surface to be cleaned. This increases the contact area and fit between the second wiper section and the surface, improving lateral wiping performance. Furthermore, the rebound force generated by the elastic bending ensures the second wiper section remains firmly in contact with the surface, maintaining good wiping performance even on uneven surfaces. The 3-5mm bending distance ensures sufficient wiping pressure for the second wiper section and prevents excessive deformation that could cause wiper blade wear or jamming.

[0015] In one possible implementation, the front wiper can be raised or lowered relative to the mounting base; when the front wiper is lowered to its lowest position, the front wiper is in the working position.

[0016] By configuring the front wiper unit to be raised and lowered relative to the mounting base, with its working position at the lowest level, the front wiper unit can rise and detach from the surface to be cleaned during non-cleaning states (such as transport, crossing obstacles, or standby), reducing unnecessary wear and resistance. During cleaning, it descends to the lowest position, ensuring that the first and second wiping sections accurately engage with the surface to be cleaned. This correspondence between the raising and lowering structure and the working position guarantees that the wiper blades achieve the preset wiping posture after each descent, ensuring consistent wiping performance.

[0017] In one possible implementation, the bottom of the second wiper section is naturally lower than the bottom of the first wiper section.

[0018] This design ensures that when the front wiper descends to contact the ground, the second wiping section contacts the surface to be cleaned before the first wiping section. This allows the lower-positioned second wiping section to make timely and reliable contact with the surface when the floor brush assembly just begins to turn or is in a non-straight backward pull, thereby collecting and diverting lateral water stains, improving wiping response speed and cleaning effect during turns. It also reduces wear on the first wiping section during turns, extending its service life.

[0019] In one possible implementation, the bottom of the second wiper section is 3mm to 5mm lower than the bottom of the first wiper section.

[0020] In its natural state, the bottom of the second wiper section is 3mm to 5mm lower than the bottom of the first wiper section. This ensures that the second wiper section contacts the surface to be cleaned before the first wiper section, even with low friction. Specifically, if the height difference is too small (e.g., less than 3mm), the second wiper section may not reliably contact the surface to be cleaned first during slight turns or when the surface is uneven, resulting in inconsistent side wiping performance. If the height difference is too large (e.g., more than 5mm), it may cause the second wiper section to wear out prematurely or excessively, or generate unnecessary excessive resistance when the floor brush assembly is pulled straight back. The 3mm to 5mm range ensures timely side wiping during turns while balancing the durability of the wiper components and the smoothness of equipment movement.

[0021] In one possible implementation, the second wiper section includes a first end and a second end opposite to each other along the forward direction of the floor brush assembly, the first end being close to the first wiper section; from the first end to the second end, the second wiper section gradually tilts inward toward the floor brush assembly.

[0022] By gradually tilting the second wiping section inward from its first end near the first wiping section to its second end away from the first wiping section, a gradually narrowing water channel is formed between the second wiping section and the cleaning element. As the floor brush assembly moves backward, water stains on the sides are gradually squeezed inward and eventually flow into the cleaning area of ​​the cleaning element. Compared to a structure with equal width or outward expansion, this gradually converging design can more efficiently gather water stains on the sides and reduce water residue on the surface of the second wiping section.

[0023] In one possible implementation, the second wiper section includes a third end and a fourth end opposite each other along the height direction of the floor brush assembly, with the fourth end closer to the surface to be cleaned; from the third end to the fourth end, the second wiper section gradually tilts inward toward the floor brush assembly.

[0024] By gradually tilting the second wiping section inward from the third end at the top to the fourth end at the bottom, the bottom of the second wiping section can bend inward towards the cleaning component when it contacts the surface to be cleaned. When elastic bending occurs, this structure can convert the reaction force of the surface to be cleaned into an inward bending force, making the bending direction more controllable and avoiding irregular deformation to the outside or in other directions.

[0025] In one possible implementation, the second end of the second wiper section has a bend that bends inward toward the inside of the floor brush assembly; the bend is located near the fourth end, and in the extending direction of the bend, the top surface of the bend gradually slopes downward.

[0026] By incorporating a bend at the second end of the second wiper section, and positioning the bend near the fourth end at the bottom, with the top surface of the bend gradually sloping downwards, the end of the second wiper section forms a tongue-shaped structure facing the cleaning area. When the brush assembly turns, the water collected by the second wiper section is further contained and guided inwards by this bend as it flows towards the cleaning area, effectively preventing water from escaping from the outer side of the end of the second wiper section. This ensures that the water is more thoroughly collected within the cleaning area of ​​the cleaning component, reducing cleaning dead zones.

[0027] In one possible implementation, the second wiper section has a first groove on the side opposite to the cleaning element; the first groove extends along the extension direction of the second wiper section.

[0028] By setting the first groove, when the second wiper section is subjected to ground pressure, the first groove can absorb some of the deformation stress, reduce the overall stiffness of the wiper strip, and make the second wiper section easier to bend inward.

[0029] In one possible implementation, the second wiper section has a second groove on the side facing the cleaning component, and the second groove extends along the extending direction of the second wiper section.

[0030] By setting a second groove, the second wiper section is provided with space to bend inward when it is bent, thus avoiding wrinkles or local stress concentration when the wiper strip is bent.

[0031] In one possible implementation, there are multiple second grooves, which are spaced apart along the height direction of the floor brush assembly; some of the second grooves correspond to the first groove.

[0032] By setting multiple second grooves spaced apart along the height direction, and making some of the second grooves correspond to the first grooves, a multi-layered elastic deformation structure can be formed. The corresponding arrangement of the first and second grooves allows the cross-section of the second wiper section to be I-shaped or H-shaped, which can ensure the overall strength of the structure, provide good elastic deformation capacity, prevent stress concentration and breakage when the second wiper section is bent, and extend the service life of the second wiper section.

[0033] In one possible implementation, the front wiper includes a support portion; a first wiper section and a second wiper section are integrally formed with the support portion; both the first wiper section and the second wiper section extend downward from the bottom of the support.

[0034] By incorporating a support unit and integrally molding the first and second wiper sections with it, the overall structure of the wiper blade becomes more stable, preventing loose connections or relative displacement that may occur with separate structures. The support unit, located at the top of the wiper sections, provides a rigid mounting base for both sections. The integrated molding process also reduces the number of parts and assembly steps, lowering manufacturing costs.

[0035] In one possible implementation, the first wiper section and the second wiper section are spaced apart.

[0036] By separating the first and second wiper sections, they can deform and displace independently during operation. When the second wiper section bends inward under lateral pressure, the first wiper section remains unaffected, maintaining its original wiping posture. Furthermore, this separation allows the first and second wiper sections to utilize different material properties or dimensional parameters according to their respective functional requirements. For example, the second wiper section can use a softer material to facilitate bending, while the first wiper section can use a harder material to ensure a straight-line wiping effect.

[0037] In one possible implementation, the front wiper includes a base that is fixedly connected to a support; wherein the base is located inside the support, and a portion of the base is embedded within the support.

[0038] By setting a base and positioning it inside the support unit, partially embedded within it, a double-layer structure can be formed. The base serves as an inner skeleton, providing structural stability to the support unit and enhancing the overall strength of the front wiper assembly. It also connects to the lifting mechanism on the floor brush assembly, evenly distributing the lifting force throughout the support unit. The partially embedded structure of the base creates a mechanical interlock between the base and the support unit, preventing relative slippage or disengagement during use, thereby improving the reliability and lifespan of the front wiper assembly.

[0039] In one possible implementation, the base includes a connecting portion; wherein the connecting portion includes a first connecting segment and two second connecting segments, the first connecting segment extending axially along the cleaning component, the two second connecting segments being located at both ends of the first connecting segment and extending laterally toward the cleaning component; the first connecting segment is embedded in a support portion above the first wiper segment, and the second connecting segments are embedded in a support portion above the second wiper segment.

[0040] By setting the connecting part of the base as a first connecting segment and two second connecting segments, and embedding the first connecting segment inside the support part above the first wiper segment and the second connecting segment inside the support part above the second wiper segment, the support parts for the first wiper segment and the support parts for the second wiper segment can both be supported by the base. This ensures that each wiper segment can receive rigid support from the base at every position in its extension direction, avoiding collapse or uneven deformation caused by local lack of support.

[0041] In one possible implementation, both the first connecting segment and the second connecting segment are provided with multiple spaced through-hole structures; the support and the base are integrally injection molded so that a portion of the structure of the support and a portion of the structure of the base are cross-joined.

[0042] By incorporating multiple spaced through-hole structures in the first and second connecting sections and using integral injection molding to interlock parts of the support and base structures, a composite structure similar to reinforced concrete can be formed. During injection molding, the molten support material flows into the through-hole structures and, after solidification, forms an inseparable mechanical interlock with the base. Compared to simple adhesive or snap-fit ​​connections, this interlocking structure offers higher bonding strength and peel resistance, thereby extending the service life of the front wiper component.

[0043] In one possible implementation, a transition angle is formed between the first connecting segment and the second connecting segment; the dimension of the transition angle in the axial direction of the cleaning component is greater than the dimension of the second connecting segment in the axial direction of the cleaning component; the dimension of the transition angle in the extension direction of the second wiper segment is greater than the dimension of the first connecting segment in the extension direction of the second wiper segment.

[0044] By setting the aforementioned transition angle, the cross-joint area between the support and the base at the transition angle is significantly increased, forming a locally thickened reinforced structure. The transition angle is the intersection of two force directions in the base, making it most prone to stress concentration and fatigue fracture. By increasing the planar dimensions of the transition angle, the joint area between the base and the support can be increased, preventing cracking or delamination at the joint surface, thereby improving the overall strength and reliability of the base and extending the service life of the front wiper component.

[0045] In one possible implementation, the support portion is fully disposed on the outside of the first connecting section and the second connecting section.

[0046] By fully enclosing the support portion on the outside of the first and second connecting sections, each connecting section of the base is completely covered by the support portion material. This fully enclosed structure increases the bonding area between the base and the support portion, improving the bonding strength. Furthermore, the support portion forms a uniform elastic buffer layer on the outside of the base, effectively absorbing energy and reducing the impact force transmitted to the base when the first or second wiper section is subjected to impact or vibration.

[0047] In one possible implementation, the thickness of the first connecting segment and the second connecting segment is less than the thickness of the base in the height direction of the floor brush assembly; the top and bottom surfaces of the support are flush with the top and bottom surfaces of the base, respectively.

[0048] By setting the thickness of the first and second connecting sections to be less than the thickness of the main body of the base, space can be reserved for the injection molding of the support. After injection molding, the top and bottom surfaces of the support are flush with the top and bottom surfaces of the base, forming a flat outer surface. This facilitates the installation and sealing of the front wiper component, avoiding assembly interference or additional friction during wiping caused by uneven surfaces. In addition, the thinning design of the connecting sections reduces the material used in the base, thereby reducing cost and weight, while the main body of the base (the thicker area) still maintains sufficient structural strength.

[0070] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0071] This application provides a cleaning device. The cleaning device may include a robotic vacuum cleaner, a floor scrubber, or other equipment capable of cleaning a surface to be cleaned. For example, the surface to be cleaned may be a surface that needs cleaning. The following description primarily uses the scenario of the cleaning device cleaning a surface to be cleaned as an example to illustrate the structure of the cleaning device.

[0072] Figure 1 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application.

[0073] It should be noted that, for ease of description, in the embodiments of this application, the height direction of the cleaning equipment is taken as the z-direction, the axial direction of the cleaning component is taken as the x-direction, and the forward direction of the cleaning equipment is taken as the y-direction.

[0074] Please refer to Figure 1 This application provides a cleaning device 100. The cleaning device 100 may include devices such as a robotic vacuum cleaner, a floor scrubber, or a surface to be cleaned. For example, the surface to be cleaned may be a surface to be cleaned, etc. The following description mainly uses the scenario of the cleaning device 100 cleaning a surface to be cleaned as an example to illustrate the structure of the cleaning device 100.

[0075] Specifically, the cleaning device 100 may include a body 10 and a floor brush assembly 20. The floor brush assembly 20 is located at the bottom of the body 10 and is used to clean the surface to be cleaned. A handle is provided at the end of the body 10 away from the surface to be cleaned, so that the user can hold and push the cleaning device 100 to perform the operation.

[0076] The floor brush assembly 20 may include a mounting base 21 and a cleaning component 22. The mounting base 21 is rotatably connected to the bottom of the main body of the device, and the cleaning component 22 is located on the side of the mounting base 21 facing the surface to be cleaned. During operation, the cleaning component 22 rotates relative to the mounting base 21 and brushes up and removes dirt by directly contacting the surface to be cleaned.

[0077] The cleaning device 100 may also include a clean water tank (not shown in the figure), which may be installed on the floor brush assembly 20 or the body 10, for supplying clean water to the floor brush assembly 20 or the surface to be cleaned, so that the cleaning component 22 can better clean the surface to be cleaned.

[0078] The cleaning equipment 100 may also include a wastewater tank (not shown in the figure). The wastewater tank is installed above the floor brush assembly 20, on the side away from the surface to be cleaned. The wastewater tank has a dirt storage chamber. A suction port is provided on the mounting base 21 of the floor brush assembly 20, and the suction port is connected to the dirt storage chamber through a dirt transfer pipe. During the operation of the suction port, the gas in the dirt storage chamber is continuously drawn away, thereby creating a negative pressure environment in the dirt storage chamber and the dirt transfer pipe, so that the dirt generated by the floor brush assembly 20 during operation is sucked into the dirt storage chamber through the suction port and the dirt transfer pipe for centralized storage. In this way, after the cleaning equipment 100 completes the cleaning operation, the user can clean the dirt in the wastewater tank.

[0079] It should be noted that the dirt in the cleaning process can include the wastewater, impurities, and mixtures of dirt generated during the cleaning process mentioned above.

[0080] To improve mobility, the floor brush assembly 20 may also include a walking mechanism. The walking mechanism is mounted on the mounting base 21. When the user pushes the handle, the walking mechanism can move the entire cleaning device 100 in different directions, allowing the floor brush assembly 20 to cover a wider area.

[0081] When the user operates the cleaning device 100 to clean the surface to be cleaned, the user will push the handle to drive the cleaning device 100 to move back and forth according to the cleaning needs. The forward pushing process mainly relies on the rotation of the cleaning component 22 to complete the wiping operation on the surface to be cleaned, while the backward pulling process is the cleaning finishing action to clean and collect the water stains and dirt left on the surface to be cleaned after the forward wiping.

[0082] During the cleaning process, as the cleaning component 22 rotates and scrubs the surface to be cleaned, water stains will form on the surface. If these water stains are not removed in time, they can easily remain and affect the cleaning effect. Therefore, in related technologies, a scraper is provided on the front side of the cleaning component 22 along the forward direction of the cleaning device 100, corresponding to the side of the mounting base 21 facing the surface to be cleaned. When the user pulls the cleaning device 100 backward to finish, the scraper comes into contact with the surface to be cleaned. As the cleaning device 100 moves backward, the scraper scrapes and collects the water stains on the surface to be cleaned towards the cleaning component 22.

[0083] However, when the equipment enters situations involving backward turning, edge-hugging maneuvers, or continuous direction changes, the relative trajectory of the floor brush assembly 20 to the ground changes from a straight line to an arc. The traditional front scraper edge provides insufficient coverage on both sides of the turning path, especially in the edge transition area, leaving noticeable water stains on the surface to be cleaned, thus affecting the cleaning effect. Therefore, how to solve the problem of water stain residue when the cleaning equipment makes a 100° turn and improve the integrity and effectiveness of the cleaning operation has become a technical problem that needs to be solved.

[0084] To address the aforementioned technical problems, this application provides a cleaning device 100. This cleaning device 100 includes a front squeegee 30 positioned on the front side of a floor brush assembly 20. The front squeegee 30 may include a first squeegee section 31 extending axially along the cleaning component 22 and a second squeegee section 32 extending laterally towards the cleaning component 22. The bottom of the second squeegee section 32 is inclined inwards towards the floor brush assembly 20. Through the segmented configuration and inwardly inclined flow-guiding relationship of the front squeegee 30, the cleaning device 100 can more effectively gather and guide edge liquids during straight-line and turning cleaning, thereby improving the floor brush assembly 20's ability to cover wastewater in turning areas, reducing water residue on the surface to be cleaned, and enhancing cleaning effectiveness and user experience.

[0085] The cleaning equipment 100 provided in the embodiments of this application will be further described below with reference to the accompanying drawings.

[0086] like Figure 1 and Figure 2 As shown in the illustration, this application provides a cleaning device 100, which may include a body 10 and a floor brush assembly 20 movably disposed at the bottom of the body 10. The floor brush assembly 20 may include a mounting base 21, a cleaning component 22, and a front wiping component 30. The cleaning component 22 is rotatably disposed on the front side of the mounting base 21 and is used to clean the surface to be cleaned when rotating relative to the mounting base 21. The front wiping component 30 is disposed on the front side of the cleaning component 22 and is used to wipe away water stains on the surface to be cleaned when the device is pulled back for cleaning.

[0087] Specifically, the mounting base 21 is rotatably connected to the body 10, allowing the floor brush assembly 20 to rotate relative to the body 10. When the cleaning device 100 is pushed forward or pulled back, the floor brush assembly 20 moves forward or backward under the drive of the body 10. At this time, the cleaning component 22 can rotate around its own axis, allowing it to sweep and roll up dirt along its path, completing the cleaning operation on the surface to be cleaned. However, during the cleaning process, the contact between the cleaning component 22 and the surface to be cleaned may leave water stains, which remain on the surface and affect the cleaning effect. The cleaning component 22 can be a roller brush or other cleaning structures; this embodiment does not limit this.

[0088] In some embodiments, such as Figure 2 As shown, the cleaning device 100 may further include a rear wiper 40, which is disposed on the mounting base 21 and located behind the cleaning component 22. The rear wiper 40 is configured to contact the surface to be cleaned, and during the forward movement of the cleaning device 100, it can wipe away water stains remaining on the cleaning component 22 during the cleaning process, thereby further reducing water stain residue.

[0089] Figure 3 This is a schematic diagram of the structure of the front wiper 30 of the floor brush assembly 20 of a cleaning device 100 provided in an embodiment of this application. Figure 4 for Figure 3 A magnified view of part A in the diagram.

[0090] See Figure 2 , Figure 3 and Figure 4 As shown, along the forward direction y of the floor brush assembly 20, the cleaning component 22 has a front side and a rear side. The front wiper 30 is provided at the bottom of the mounting base 21 and is located on the front side of the cleaning component 22.

[0091] like Figure 3 As shown, the front wiper assembly 30 may include a first wiping section 31 and a second wiping section 32. The first wiping section 31 extends axially along the cleaning member 22. Two second wiping sections 32 are located at opposite ends of the first wiping section 31 and extend laterally toward the cleaning member 22. The bottom of the second wiping sections 32 is inclined toward the inner side of the floor brush assembly 20. That is, the first wiping section 31 is located on the front side of the cleaning member 22 and extends axially along the cleaning member 22, while the second wiping sections 32 are located on the outer side of the axial end of the cleaning member 22.

[0092] It should be noted that "the bottom of the second wiping section 32 is inclined toward the inside of the floor brush assembly 20" means that the bottom edge of the second wiping section 32 is closer to the side edge of the cleaning component 22 than its top, forming a slope or arc surface that narrows inward.

[0093] For example, the first wiper section 31 and the second wiper section 32 can be integrally formed, or they can be set separately and then fixedly connected. This application embodiment does not specifically limit this.

[0094] The cleaning device 100 in this embodiment of the application can achieve a lateral water gathering effect when driving in a straight line and a guiding water wiping effect when turning by setting the bottom of the second wiping section 32 to be tilted towards the inside of the floor brush assembly 20.

[0095] It should be understood that the effects of tilting inward and tilting outward are not the same. Through in-depth research, it has been found that when tilting outward, if the user turns to one side, such as to the right, the left wiper section will collect the internal wastewater and bring it to the roller brush, thus clearing the wastewater on the left side. However, the right wiper end will push the wastewater on the right side, resulting in more wastewater on the right side.

[0096] However, when tilting inwards, the left-side wiper section can still remove the water when turning to the right, but because the right-side wiper section bends inwards, it will not push the sewage on the right side or spread it out, resulting in more sewage accumulating on the right side.

[0097] Specifically, when driving in a straight line, the inwardly inclined second wiper section 32 forms a shielding structure in the side. When the cleaning component 22 rotates and flings water stains to the side, the second wiper section 32 can shield these water stains and guide them inward, concentrating them on the cleaning area of ​​the cleaning component 22, where they are absorbed or carried away by the cleaning component 22, effectively reducing water marks left on both sides of the surface to be cleaned after cleaning.

[0098] When the cleaning device 100 turns, the floor brush assembly 20 turns along with the main body 10, and the water splashed laterally by the cleaning component 22 easily escapes outward under the action of centrifugal force. By setting the second wiping section 32 to be tilted inward, the bottom edge of the second wiping section 32 is closer to the side edge of the cleaning component 22, forming a guide channel that narrows inward. During the turn, the water splashes moving outward are intercepted by the second wiping section 32 and guided back to the cleaning area of ​​the cleaning component 22, thereby reducing the lateral outward flow of water splashes on the turning path, and the lateral wiping of the second wiping section 32 can reduce the arc-shaped water marks left on the outside of the cleaning path after the turn.

[0099] Furthermore, the inward-sloping second wiper section 32 has the advantage of bidirectional water gathering when turning. Specifically, both the second wiper section 32 located on the inside of the turn and the second wiper section 32 located on the outside of the turn can wipe water stains inward. Compared to when the second wiper section 32 is set to be outward-sloping, the second wiper section 32 located on the outside of the turn will push water stains outward, forming more obvious water marks on the outside of the turning path. In this solution, regardless of whether the floor brush assembly 20 turns left or right, the slope of the second wiper section 32 located on the outside of the turn faces inward, which can gather water stains towards the cleaning area.

[0100] In one possible implementation, the second wiper section is elastic. The front wiper 30 has a working position in which both the first wiper section 31 and the second wiper section 32 abut against the surface to be cleaned. In the working position, the bottom of the second wiper section 32 elastically bends 3-5 mm toward the inside of the floor brush assembly 20 under the pressure of the surface to be cleaned, for example, 3 mm, 4 mm, or 5 mm. In this embodiment, the inward bending dimension of the second wiper section 32 is not further limited.

[0101] For example, the second wiper section 32 can be made of a material with good elasticity and wear resistance, such as thermoplastic elastomers, rubber, silicone, or polyurethane. This allows the second wiper section 32 to undergo elastic deformation when subjected to external force and return to its original shape after the force is removed, thereby maintaining good wiping performance and structural integrity during repeated wiping. In this embodiment, the specific material of the second wiper section 32 is not further limited.

[0102] It should be noted that the aforementioned 3-5mm bending distance is the distance by which the bottom edge of the second wiper section 32 offsets inward relative to its natural state (the static state of the front wiper 30 when no additional lifting driving force is applied and it is only affected by its own weight and the mounting structure) under the normal working condition of the front wiper 30. This distance can be controlled by adjusting the material hardness, cross-sectional shape, tilt angle of the second wiper section 32, and the downward pressure of the front wiper 30 in the working position. In this embodiment, no further limitations are made.

[0103] When the bending distance is less than 3mm, the deformation may be insufficient, failing to form an effective lateral shield, allowing water stains to easily escape from the side, resulting in an unsatisfactory wiping effect. When the bending distance is greater than 5mm, the deformation is too large, leading to increased pulling resistance, accelerated material fatigue and aging, and potentially causing the second wiping section 32 to get caught in the bottom of the cleaning component 22, causing interference.

[0104] Therefore, controlling the bending distance within the range of 3-5mm allows the second wiper section to undergo controllable elastic deformation upon contact with the surface to be cleaned. This increases the contact area and adhesion between the second wiper section 32 and the surface, improving the lateral wiping effect. Furthermore, the rebound force generated by the elastic bending ensures that the second wiper section 32 remains firmly attached to the surface, maintaining good wiping performance even on uneven surfaces. The 3-5mm bending distance ensures sufficient wiping pressure for the second wiper section 32 and prevents excessive deformation that could lead to wiper strip wear or jamming.

[0105] In one possible implementation, such as Figure 4 As shown, the bottom of the second wiper section is lower than the bottom of the first wiper section 31 in its natural state.

[0106] This design ensures that when the front wiper assembly 30 descends and contacts the ground, the second wiping section 32 contacts the surface to be cleaned before the first wiping section 31. As the front wiper assembly 30 continues to descend, the second wiping section 32 has sufficient leeway to bend inwards towards the cleaning assembly 22, resulting in a tighter fit against the surface. This allows the lower-positioned second wiping section 32 to make timely and reliable contact with the surface when the floor brush assembly 20 is just beginning to turn or in a non-straight backward pull, thereby collecting and guiding lateral water stains and improving wiping response speed and cleaning effect during turns. It also reduces wear on the first wiping section 31 during turns, extending its service life.

[0107] In one possible implementation, under natural conditions, the bottom of the second wiper section is 3mm to 5mm lower than the bottom of the first wiper section 31. Figure 4 (represented by h in the text). For example, the bottom of the second wiper section 32 is 3mm, 3.5mm, 4.0mm, 4.5mm to 5mm lower than the bottom of the first wiper section 31. In this embodiment, the dimension by which the bottom of the second wiper section 32 is lower than the bottom of the first wiper section 31 is not further limited.

[0108] In its natural state, the bottom of the second wiper section 32 is 3mm to 5mm lower than the bottom of the first wiper section 31. This ensures that the second wiper section 32 contacts the surface to be cleaned before the first wiper section 31, even with low friction. Specifically, if the height difference is too small (e.g., less than 3mm), the second wiper section 32 may not reliably contact the surface to be cleaned first during slight turns or when the surface is uneven, resulting in inconsistent side wiping performance. If the height difference is too large (e.g., more than 5mm), it may cause the second wiper section 32 to wear prematurely and excessively, or generate unnecessary excessive resistance when the floor brush assembly 20 is pulled straight back. The 3mm to 5mm range ensures timely side wiping during turns while balancing the durability of the wiper components and the smoothness of equipment movement.

[0109] In one possible implementation, such as Figure 4 As shown, the first wiper section and the second wiper section 32 are spaced apart.

[0110] Specifically, a gap is formed between the first wiper section 31 and the second wiper section 32, and the two are physically separated from each other.

[0111] By separating the first wiper section 31 and the second wiper section 32, they can deform and displace independently during operation. When the second wiper section 32 bends inward under lateral pressure, the first wiper section 31 remains unaffected by the bending and maintains its original wiping posture. Furthermore, this separation allows the first and second wiper sections 31 and 32 to utilize different material properties or dimensional parameters according to their respective functional requirements. For example, the second wiper section 32 can use a softer material to facilitate bending, while the first wiper section 31 can use a harder material to ensure a straight wiping effect.

[0112] Furthermore, the separate arrangement can reduce the stress transmission path between the first wiper section 31 and the second wiper section 32, preventing adverse effects on the first wiper section 31 when the second wiper section 32 bends. Optionally, the gap between the first wiper section 31 and the second wiper section 32 can be 1mm to 2mm, which ensures that both can deform independently and effectively prevents water from leaking through the gap.

[0113] In some embodiments, the front wiper 30 can be raised and lowered relative to the mounting base 21. When the front wiper 30 is lowered to its lowest position, the front wiper 30 is in the working position.

[0114] It should be noted that the working position refers to the position of the front wiper 30 relative to the mounting base 21 when it is working normally during the pull-back process.

[0115] For example, in the non-working position, the front wiper 30 can be in a raised position, in which at least a portion of the structure of the front wiper 30 is separated from the surface to be cleaned. For instance, the raised position can include a first raised position and a second raised position. In the first raised position, the second wiping segment 32 is in contact with the surface to be cleaned, and the first wiping segment 31 is separated from the surface to be cleaned. In the second raised position, both the first wiping segment 31 and the second wiping segment 32 are separated from the surface to be cleaned. Of course, other positioning methods are possible in other embodiments, and are not further limited in this application embodiment.

[0116] For example, the floor brush assembly 20 may include a lifting member (not shown in the figure). The lifting member is vertically detachable from the mounting base 21 and located in front of the cleaning member 22. A front wiper 30 is connected to the bottom of the lifting member. In this embodiment, the specific structure of the lifting member is not further limited.

[0117] By setting up a lifting component to drive the front wiper component 30 to rise and fall, a stable and reliable foundation for the lifting and falling motion of the front wiper component 30 can be provided, ensuring that the first wiping section 31 and the two second wiping sections 32 can perform the lifting and falling motion as a whole, thereby improving the consistency of the motion.

[0118] By combining the multi-position control scheme of the front wiper 30 with the lower physical structure of the bottom of the second wiping section 32 of the front wiper 30, refined functional matching and energy efficiency optimization can be achieved.

[0119] By configuring the front wiper component to be raised and lowered relative to the mounting base 21, with its working position at the lowest level, the front wiper component 30 can rise and detach from the surface to be cleaned when not in a cleaning state (such as during transport, crossing obstacles, or standby), reducing unnecessary wear and resistance. In a cleaning state, it lowers to the lowest position, ensuring that the first wiping section 31 and the second wiping section 32 accurately engage with the surface to be cleaned. This correspondence between the raising and lowering structure and the working position ensures that the wiper blades achieve the preset wiping posture after each descent, guaranteeing consistent wiping performance.

[0120] Figure 5 This is a cross-sectional structural diagram of the second wiping section 32 of the front wiping element 30 of the floor brush assembly 20 of a cleaning device 100 provided in an embodiment of this application. Figure 5 The diagram shown is a cross-sectional view of the front wiper unit from a top angle.

[0121] In one possible implementation, see Figure 5 As shown, the second wiper section 32 includes a first end 321 and a second end 322 opposite to each other along the forward direction of the floor brush assembly 20, with the first end 321 close to the first wiper section 31. From the first end 321 to the second end 322, the second wiper section 32 gradually slopes inward toward the inside of the floor brush assembly 20.

[0122] Figure 5 The plane s1 shown is perpendicular to the x-direction. (As shown...) Figure 5 As shown, the outer contour of the second wiping section 32 extends from the first end 321 to the second end 322. The second wiping section 32 gradually shifts towards the inside of the floor brush assembly 20, that is, it shifts in the direction away from s1, so that a gradually narrowing water channel is formed between the second wiping section 32 and the cleaning component 22.

[0123] In this application, the tilt angle of the second wiper section 32 from the first end 321 to the second end 322 is not limited, for example, it can be 5° to 10°.

[0124] By gradually tilting the second wiper section 32 inward from its first end 321 near the first wiper section 31 to its second end 322 away from the first wiper section 31, a gradually narrowing water channel is formed between the second wiper section 32 and the cleaning component 22. As the floor brush assembly 20 moves backward, the water on the side is gradually squeezed inward and eventually flows into the cleaning area of ​​the cleaning component 22. Compared to a structure with equal width or outward expansion, this gradually converging design can more efficiently gather water on the side and reduce water retention on the surface of the second wiper section 32.

[0125] In some embodiments, such as Figure 5 As shown, a baffle 35 is provided on the inner side of the first wiper section 31, and the bottom of the baffle 35 can be flush with the bottom of the first wiper section 31 (see reference). Figure 7 (As shown). Specifically, the shielding edge 35 is disposed at the gap between the first wiper section 31 and the second wiper section 32, and the orthogonal projection of the shielding edge 35 in a plane perpendicular to the x-direction can cover the gap between the first wiper section 31 and the second wiper section 32.

[0126] For example, the shielding edge 35 can be an arc-shaped structure, with the convex surface of the arc-shaped structure facing the physical gap. One end of the shielding edge 35 is smoothly connected to the first wiper section 31, and the other end extends toward the second wiper section 32, and exceeds the first end 321 of the second wiper section 32 in the y direction. This can shield the gap between the first wiper section 31 and the second wiper section 32.

[0127] By incorporating a baffle edge 35, the structural gap between the separate or spaced first wiper section 31 and second wiper section 32 can be cleverly compensated. During wiping operations, water or dirt can easily escape or splash through this gap, resulting in incomplete cleaning and potentially soiling the cleaned area. The baffle edge 35 in this application seals this gap, effectively blocking and guiding water and dirt attempting to pass through it. This allows the water and dirt to be guided back along the curved surface of the edge into the wiping path of the first wiper section 31 or the second wiper section 32, ultimately converging on the cleaning component 22. This improves the sealing performance and cleaning efficiency of the wiping mechanism, making the overall structure of the front wiper component 30 more complete and enhancing its ability to handle complex stains.

[0128] Figure 6 This is a cross-sectional view of the second wiping section 32 of the front wiping element 30 of the floor brush assembly 20 of a cleaning device 100 provided in this application embodiment, taken from another angle. Figure 6 This is a schematic diagram of the cross-sectional structure of the front wiper unit viewed from a 30° rear angle.

[0129] like Figure 6As shown, the second wiper section 32 may include a third end 323 and a fourth end 324 opposite to each other along the height direction of the floor brush assembly 20, with the fourth end 324 closer to the surface to be cleaned. From the third end 323 to the fourth end 324, the second wiper section 32 gradually slopes inward toward the floor brush assembly 20.

[0130] Specifically, the third end 323 is the top end of the second wiper section 32, and the fourth end 324 is the bottom end of the second wiper section 32. Figure 6 The plane s2 shown is parallel to the z-direction, which means it is perpendicular to the surface to be cleaned. Figure 6 As shown, the outer contour of the second wiper section 32 gradually shifts towards the inside of the floor brush assembly 20 from top to bottom, that is, it shifts in the direction of deviating from s2, forming a wedge-shaped structure that is wider at the top and narrower at the bottom.

[0131] For example, the wall thickness of the second wiper section 32 can gradually decrease from the top to the bottom, which can make the top of the second wiper section 32 have better connection strength and the bottom have better elasticity. When it descends to contact the surface to be cleaned, the bottom of the second wiper section 32 can bend inward.

[0132] By gradually tilting the second wiping section 32 inward from the third end 323 at the top to the fourth end 324 at the bottom, the bottom of the second wiping section 32 can bend inward towards the cleaning component 22 when it contacts the surface to be cleaned. When elastic bending occurs, this structure can convert the reaction force of the surface to be cleaned into an inward bending force, making the bending direction more controllable and avoiding irregular deformation to the outside or in other directions.

[0133] See also Figure 4 As shown, the second end 322 of the second wiper section 32 has a bend 325, which bends inward toward the floor brush assembly 20. The bend 325 is located near the fourth end 324, and in the extending direction of the bend 325, the top surface of the bend 325 gradually slopes downward.

[0134] Specifically, the bent portion 325 is located at the second end 322 (outer end) of the second wiper section 32 and near the bottom, and is bent inward as a whole, with the top surface gradually sloping downward to form a thin-walled tongue-shaped structure.

[0135] By providing a bend 325 at the second end 322 of the second wiper section 32, and positioning the bend 325 near the fourth end 324 at the bottom, with the top surface of the bend 325 gradually sloping downwards, the end of the second wiper section 32 forms a tongue-shaped structure facing the working area of ​​the cleaning component 22. When the brush assembly 20 turns, the side water collected by the second wiper section 32 is further caught and guided inwards by this bend 325 as it flows towards the cleaning component 22, effectively preventing water from escaping from the outer side of the end of the second wiper section 32. This ensures that the side water is more thoroughly collected within the cleaning area of ​​the cleaning component 22, reducing cleaning dead spots.

[0136] In the embodiments of this application, combined with Figure 4 and Figure 7 As shown, the second wiping section 32 has a first groove on the side facing away from the cleaning element 22. The first groove 326 extends along the extending direction of the second wiping section 32. The second wiping section 32 has a second groove 327 on the side facing the cleaning element 22, and the second groove 327 extends along the extending direction of the second wiping section 32.

[0137] By providing the first groove 326, the second wiper section 32 can absorb some of the deformation stress when subjected to ground pressure, reducing the overall stiffness of the wiper strip and making it easier for the second wiper section 32 to bend inward. By providing the second groove 327, the second wiper section 322 provides space for bending inward when bending, preventing wrinkles or localized stress concentration from forming when the wiper strip is bent.

[0138] In some embodiments, there may be multiple second grooves 327, which are spaced apart along the height direction of the floor brush assembly 20. Some of the second grooves 327 correspond to the first grooves 326.

[0139] For example, there is one first groove 326 and two second grooves 327, one of which is located near the third end 323 of the second wiper section 32, and the other is corresponding to the first groove 326.

[0140] By setting multiple second grooves 327 spaced apart along the height direction, and making some of the second grooves 327 correspond to the first grooves 326, a multi-layered elastic deformation structure can be formed. The corresponding arrangement of the first grooves 326 and the second grooves 327 allows the cross-section of the second wiper section 32 to be I-shaped or H-shaped, which can ensure the overall strength of the structure, provide good elastic deformation capacity, prevent stress concentration and breakage when the second wiper section 32 is bent, and extend the service life of the second wiper section 32.

[0141] In one possible implementation, such as Figure 8As shown, the front wiper 30 may include a support portion 33 and a base 34. A first wiping section 31 and a second wiping section 32 are integrally formed with the support portion 33. Both the first wiping section 31 and the second wiping section 32 extend downwards from the bottom of the support. The first wiping section 31 and the second wiping section 32 are spaced apart. The base 34 is fixedly connected to the support portion 33; the base 34 is located inside the support portion 33, and a portion of the structure of the base 34 is embedded within the support portion 33.

[0142] For example, the support portion 33 and the base 34 can be made of different materials. The support portion 33 can be made of elastic materials such as thermoplastic elastomer (TPE) or thermoplastic polyurethane (TPU) to ensure the wiping performance and elastic recovery capability of the first wiper section 31 and the second wiper section 32. The base 34 can be made of rigid materials such as polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS) to ensure the structural strength of the base 34 and the reliability of its connection with the lifting mechanism.

[0143] By incorporating the support portion 33 and integrally molding the first wiper section 31 and the second wiper section 32 with the support portion 33, the overall structure of the wiper blade becomes more stable, preventing loose connections or relative displacement that may occur with separate structures. The support portion 33, located at the top of the wiper sections, provides a rigid mounting base for the first and second wiper sections 31 and 32. The integral molding process also reduces the number of parts and assembly steps, lowering manufacturing costs.

[0144] By setting a base 34 and positioning it inside and partially embedded within the support portion 33, a double-layer structure can be formed. Part of the base 34 serves as an inner skeleton, providing structural stability to the support portion 33 and enhancing the overall strength of the front wiper 30. It can also be used to connect with the lifting mechanism on the floor brush assembly 20, evenly transmitting the lifting driving force to the entire support portion 33. The partially embedded structure of the base 34 creates a mechanical interlock between the base 34 and the support portion 33, preventing relative slippage or disengagement during use, thereby improving the reliability and service life of the front wiper 30.

[0145] In one possible implementation, such as Figure 9 As shown, the base 34 may include a connecting portion 341. The connecting portion 341 is used to connect with the support portion 33 to enhance the bonding strength between the base 34 and the support portion 33.

[0146] For example, the connecting portion 341 may include a first connecting segment 3411 and two second connecting segments 3412. The first connecting segment 3411 extends axially along the cleaning member 22, and the two second connecting segments 3412 are located at both ends of the first connecting segment 3411 and extend laterally toward the cleaning member 22. That is, the first connecting segment 3411 and the two second connecting segments 3412 of the connecting portion 341 are located on three sides of the base 34, forming a "U"-shaped layout structure. The first connecting segment 3411 is embedded in the support portion 33 above the first wiper section 31, and the second connecting segments 3412 are embedded in the support portion 33 above the second wiper section 32.

[0147] This three-sided layout design allows for a larger connection area and more connection directions between the base 34 and the support 33, thereby improving the connection reliability and pull-out resistance between the two.

[0148] It should be noted that "embedded" here means that the connecting part 341 of the base 34 is embedded inside the support part 33 and is wrapped by the material of the support part 33, forming a tight embedded joint structure. This structure allows the base 34 and the support part 33 to be fused at the material level, forming a mechanical interlock, which is not easy to separate even under large pulling force, thus ensuring the reliability and stability of the connection.

[0149] By configuring the connecting portion 341 of the base 34 as a first connecting segment 3411 and two second connecting segments 3412, and embedding the first connecting segment 3411 within the support portion 33 above the first wiper segment 31 and the second connecting segments 3412 within the support portion 33 above the second wiper segment 32, the support portion 33 of the first wiper segment 31 and the support portion 33 of the second wiper segment 32 can both be supported by the base 34. This ensures that each wiper segment can receive rigid support from the base 34 at every position in its extension direction, avoiding collapse or uneven deformation caused by local lack of support.

[0150] In one possible implementation, both the first connecting segment 3411 and the second connecting segment 3412 are provided with multiple spaced through-hole structures 3413. The support portion 33 and the base 34 are integrally injection molded so that a portion of the structure of the support portion 33 intersects with a portion of the structure of the base 34.

[0151] For example, the through-hole structure 3413 can be a circular hole, an elliptical hole, or an oblong hole, and multiple through holes are arranged at intervals along the extension direction of the connecting segment. In the embodiments of this application, the number and arrangement of the through-hole structures 3413 are not further limited.

[0152] By setting multiple spaced through-hole structures 3413 on the first connecting section 3411 and the second connecting section 3412, and using integral injection molding to interlock parts of the support part 33 with parts of the base 34, a composite structure similar to reinforced concrete can be formed. During injection molding, the molten material of the support part 33 flows into the through-hole structure 3413, and after solidification, it forms an inseparable mechanical interlock with the base 34. Compared with simple adhesive or snap-fit ​​connections, this interlocking structure has higher bonding strength and peel resistance, thereby extending the service life of the front wiper 30.

[0153] Figure 10 This is a partially enlarged schematic diagram of point B on the base 34 of the front wiper 30 of the floor brush assembly 20 of a cleaning device 100 provided in this application embodiment.

[0154] In one possible implementation, see Figure 10 As shown, a transition angle 3414 is formed between the first connecting segment 3411 and the second connecting segment 3412. The dimension L1 of the transition angle 3414 in the axial direction (x direction) of the cleaning member 22 is greater than the dimension L2 of the second connecting segment 3412 in the axial direction of the cleaning member 22. The dimension L3 of the transition angle 3414 in the extension direction of the second wiper section 32 is greater than the dimension L4 of the first connecting segment 3411 in the extension direction (y direction) of the second wiper section 32.

[0155] By setting the aforementioned transition angle 3414, the cross-joining portion between the support 33 and the base 34 at the transition angle 3414 is significantly increased, forming a locally thickened reinforced structure. The transition angle 3414 is the intersection point of two force directions in the base 34, making it most prone to stress concentration and fatigue fracture. By increasing the planar dimensions of the transition angle 3414, the joint area between the base 34 and the support 33 can be increased, preventing cracking or delamination at the joint surface, thereby improving the overall strength and reliability of the base 34 and extending the service life of the front wiper component 30.

[0156] For example, the support portion 33 is fully disposed on the outside of the first connecting segment 3411 and the second connecting segment 3412. That is, the support portion 33 can surround the top surface, bottom surface, outer surface, and end face of the first connecting segment 3411 and the second connecting segment 3412, so that the first connecting segment 3411 and the second connecting segment 3412 are completely enclosed inside the support portion 33. The inner surface of the first connecting segment 3411 and the second connecting segment 3412 is connected to the base 34.

[0157] By fully enclosing the support portion 33 on the outside of the first connecting section 3411 and the second connecting section 3412, each connecting section of the base 34 is completely wrapped by the material of the support portion 33. This fully enclosed structure increases the bonding area between the base 34 and the support portion 33, improving the bonding strength. In addition, the support portion 33 forms a uniform elastic buffer layer on the outside of the base 34. When the first wiper section 31 or the second wiper section 32 is subjected to impact or vibration, the support portion 33 can effectively absorb energy and reduce the impact force transmitted to the base 34.

[0158] In one possible implementation, such as Figure 11 As shown, in the height direction (z direction) of the floor brush assembly 20, the thickness n of the first connecting segment 3411 and the second connecting segment 3412 is less than the thickness m of the base 34. The top and bottom surfaces of the support portion 33 are flush with the top and bottom surfaces of the base 34, respectively.

[0159] It should be noted that the first connecting section 3411 and the second connecting section 3412 are integral structures with the same thickness. In addition, the top and bottom surfaces of the support part 33 are roughly flush with the top and bottom surfaces of the base 34, respectively, meaning they are approximately flush, not absolutely flush.

[0160] For example, the top surface of the support portion 33 can be an inclined surface with a small angle (e.g., within 5°), and the end of the inclined surface near the base 34 is flush with the top surface of the base 34. This prevents liquid from flowing to the base 34 and avoids liquid from seeping along the top surface of the support portion 33 into the joint between the base 34 and the support portion 33, thereby improving the waterproof performance and reliability of the front wiper 30.

[0161] Specifically, the inclined surface can gradually slope downwards from the end near the base 34 towards the direction away from the base 34, so that the liquid on the top surface of the support 33 flows away from the base 34 under the action of gravity and is discharged, instead of flowing towards the base 34. The inclination angle can be controlled within 5° to ensure the guiding effect while avoiding interference with other components. Preferably, the inclination angle can be 1° to 3°, but this is not further limited in the embodiments of this application.

[0162] For example, the first connecting segment 3411 and the second connecting segment 3412 can be disposed in the middle of the base 34. This ensures that the thickness of the upper and lower support portions 33 of the connecting portion 341 is substantially the same. When the base 34 is subjected to lifting tension or water scraping reaction force, the upper and lower support portions 33 can bear the load evenly, avoiding bending deformation or stress concentration caused by unilateral force. At the same time, the symmetrical thickness distribution is conducive to uniform filling and consistent shrinkage of the support portion 33 material during injection molding, ensuring molding quality and flatness, and improving the reliability and service life of the connection between the base 34 and the support portion 33.

[0163] By setting the thickness of the first connecting section 3411 and the second connecting section 3412 to be less than the thickness of the main body of the base 34, space can be reserved for the injection molding of the support part 33. After injection molding, the top and bottom surfaces of the support part 33 are flush with the top and bottom surfaces of the base 34, respectively, forming a flat outer surface. This facilitates the installation and sealing of the front wiper 30, avoiding assembly interference or additional friction during wiping caused by uneven surfaces. In addition, the thinning design of the connecting part 341 can reduce the material used in the base 34, thereby reducing cost and weight, while the main body of the base 34 (the thicker area) can still maintain sufficient structural strength.
