Abstract
Description
Technical Field
[0001] This utility model belongs to the field of floor scrubbing machine technology, specifically relating to a double-edge cleaning mechanism and a floor scrubbing machine having the double-edge cleaning mechanism. Background Technology
[0002] Floor scrubbers, as cleaning equipment that integrates water spraying, floor scrubbing, and wastewater recycling, are widely used in household and commercial floor cleaning. Their core cleaning component is typically a horizontally positioned cleaning roller (or brush), driven by a motor to rotate at high speed, scrubbing hard surfaces. To achieve cleaning of areas such as walls and corners, the industry has proposed the concept of "edge cleaning." However, because the cleaning roller needs to be mounted on the floor scrubber base via connecting arms (or brackets) on both sides, these connecting arms inevitably create cleaning dead zones between the left and right ends of the cleaning roller and the wall surface, resulting in the inability to effectively clean debris and dust in the corner area.
[0003] Therefore, there is an urgent need in this field for a mechanism that can achieve efficient double-sided edge cleaning in order to fundamentally overcome the above-mentioned defects. Utility Model Content
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution.
[0005] A double-edge cleaning mechanism includes a base, a cleaning roller rotatably mounted on the base via two sets of connecting arms, and a brush layer covering the outer circumferential surface of the cleaning roller. An outwardly extending edge-adhering member is fixedly disposed on the side of each connecting arm closest to the ground. The brush layer includes a main body layer covering the middle of the cleaning roller and elastic layers located at its axial ends. The elastic layer has an end portion partially covering the end face of the cleaning roller and a peripheral portion extending axially from the edge of the end portion. The end portion and the peripheral portion, together with the end face of the cleaning roller, form an elastic space.
[0006] The edge-adhesive element is located within the elastic space and serves to support the elastic layer as it rotates with the cleaning roller to the edge-adhesive element. The supported portion of the elastic layer is either flush with or protrudes axially from the outer surface of the connecting arm. By providing the edge-adhesive element on the connecting arm and utilizing the special structure of the elastic layer, the elastic layers on both sides of the cleaning roller can extend axially during operation, and the elastic layer can dynamically engage and disengage with the edge-adhesive element during rotation.
[0007] In a preferred embodiment of a double-edge cleaning mechanism, the edge-adhering component is a roller capable of rotating around itself. The rotatable roller transforms the friction between the elastic layer and the roller from sliding friction to rolling friction during expansion and contraction, significantly reducing running resistance and wear on the elastic layer, extending the service life of the brush layer, and making operation smoother and quieter.
[0008] As a preferred embodiment of the double-edge cleaning mechanism, the connecting arm is provided with a fan-shaped mounting plate, and several rollers are mounted on the mounting plate, with the rollers distributed at equal angles along the fan shape. The fan-shaped mounting plate and the multiple rollers distributed at equal angles provide a continuous support surface for the elastic layer, ensuring uniform force distribution during unfolding and smoother edge-adhering action.
[0009] In a preferred embodiment of the double-edge cleaning mechanism, the distance between the axial outer end face of several rollers and the end face of the cleaning roller gradually decreases from the middle to both sides. This creates a sloping structure on the axial outer end face of the rollers, which is higher in the middle and lower on both sides. This provides ideal guidance for the unfolding of the elastic layer and avoids problems such as sudden jamming or excessive tightness of the elastic layer in certain areas, which could lead to detachment from the roller end face.
[0010] As a preferred embodiment of the double-edge cleaning mechanism, the assembly plate is provided with pressure heads on both sides to constrain the elastic layer in the retracted state, so as to avoid the elastic layer from scratching or interfering with the surrounding components such as the connecting arm, thereby improving the stability and durability of the mechanism.
[0011] A floor scrubber includes a dual-edge cleaning mechanism as described above. Integrating any of the dual-edge cleaning mechanisms into the floor scrubber gives it a thorough and highly efficient edge cleaning capability.
[0012] Compared with the prior art, this application has the following beneficial technical effects: by setting the edge fitting on the connecting arm and utilizing the special structure of the elastic layer, the elastic layer on both sides of the cleaning roller can extend axially during operation, effectively covering and cleaning the dead corners between the floor and the wall, thus solving the problem of cleaning blind spots in traditional floor scrubbers.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

In the description of this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] This utility model provides a double-edge cleaning mechanism, aiming to solve the technical problem that existing floor scrubbers cannot clean the dead corners along walls due to the structure of the connecting arm 110. (See appendix) Figures 1 to 7 The double-sided cleaning mechanism mainly includes a base 100, a cleaning roller 200, connecting arms 110, and a brush layer. The cleaning roller 200 is rotatably mounted on the base 100 via two sets of connecting arms 110. The brush layer is fixedly covered on the outer circumference of the cleaning roller 200.
[0027] The core improvement of this utility model lies in the cooperative structure between the connecting arm 110 and the brush layer. Specifically, on the side of the connecting arm 110 near the ground, an edge piece 111 extending axially outward from the cleaning roller 200 is fixedly provided. The brush layer is constructed as a composite structure, including a main body layer 210 covering the middle of the cleaning roller 200, and elastic layers 220 located at both axial ends of the cleaning roller 200. The elastic layer 220 is further composed of two parts: an end face 221 and a peripheral face 222. The end face 221 partially covers the end face of the cleaning roller 200, and the peripheral face 222 extends axially from the edge of the end face 221 towards the middle of the cleaning roller 200. The end face 221, the peripheral face 222, and the end face of the cleaning roller 200 together enclose an elastic space.
[0028] The edge-adhesive element 111 is located within this elastic space. Its function is as follows: when the elastic layer 220 rotates with the cleaning roller 200 to the working area facing the ground and comes into contact with the edge-adhesive element 111, the edge-adhesive element 111 supports the elastic layer 220, forcing the elastic layer 220 to expand axially, so that its outermost edge is flush with or protrudes from the outer surface of the connecting arm 110 in the axial direction, thereby achieving effective cleaning of dead corners along the wall. When this part of the elastic layer 220 rotates away from the working area with the cleaning roller 200, it detaches from the support of the edge-adhesive element 111 and automatically retracts under its own elasticity.
[0029] In a preferred embodiment, the edge-attaching element 111 is a roller that can rotate around its own axis. This design transforms the sliding friction between the elastic layer 220 and the edge-attaching element 111 into rolling friction, significantly reducing running resistance and wear, effectively extending the service life of the brush layer, and improving the smoothness and quietness of the mechanism's operation.
[0030] Furthermore, the connecting arm 110 is provided with a fan-shaped mounting plate 112, on which several rollers are mounted. These rollers are distributed at equal angles along the fan-shaped contour of the mounting plate 112. This arrangement provides the elastic layer 220 with a continuous support surface that matches the curvature of the end face of the cleaning roller 200, ensuring that the elastic layer 220 is subjected to uniform force and moves smoothly during unfolding. More specifically, the distance between the axial outer end face of several rollers and the end face of the cleaning roller 200 gradually decreases from the middle to both sides. Thus, the outer ends of all rollers together form a sloping guide structure that is high in the middle and low on both sides. This structure can guide the elastic layer 220 to unfold and retract smoothly and gradually during the rotation of the cleaning roller 200, effectively preventing problems such as jamming, wrinkling, or detachment from the roller end face due to local stress concentration, ensuring the reliability and consistency of the edge-fitting effect.
[0031] To ensure the stability of the mechanism during high-speed operation, the assembly plate 112 is also provided with pressure heads 113 on both sides. The pressure heads 113 are used to apply a restraining force to the elastic layer 220 when it switches between the unfolded and retracted states, so as to avoid interference and scratching between the elastic layer 220 and the surrounding fixed parts such as the connecting arm 110, thereby improving the durability and reliability of the cleaning roller 200.
[0032] This utility model also provides a floor scrubber that includes the dual-edge cleaning mechanism described in any of the above embodiments. By integrating this innovative mechanism, the floor scrubber possesses efficient and reliable dual-edge cleaning capabilities, thoroughly removing hard-to-reach corners at the junction of walls and floors, significantly improving the product's overall cleaning performance and user experience.
[0033] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
