Description

Technical Field

[0001] This utility model belongs to the field of edge brush technology, and in particular relates to an anti-tangling outward swing edge brush. Background Technology

[0002] With the continuous advancement of technology and the increasing improvement of people's living standards, robotic vacuum cleaners, as intelligent devices that can automatically clean the ground, have been widely used in various places such as homes, offices, and shopping malls, greatly saving manpower and time costs and providing people with convenient and efficient cleaning solutions.

[0003] In the overall structure of a robotic vacuum cleaner, the side brush is one of the most crucial components. It is typically installed on the edge of the vacuum cleaner's casing, and its main function is to expand the cleaning range, sweeping dust and debris from hard-to-reach areas such as corners and edges towards the vacuum cleaner's suction port, thus ensuring a comprehensive and thorough cleaning. In recent years, with the continuous expansion of the robotic vacuum cleaner market, consumers have placed higher demands on the performance and cleaning effectiveness of side brushes, prompting continuous development and innovation in side brush technology.

[0004] Currently, the side brushes of most robotic vacuum cleaners on the market generally consist of a housing and a rotating disc rotatably connected to the bottom of the housing. Multiple strip-shaped components are evenly distributed radially along the side of the rotating disc, and bristles are fixed to these strip-shaped components. The bristles are typically arranged radially along the rotating disc. When the vacuum cleaner is working, the rotating disc drives the bristles to rotate, using the friction between the bristles and the ground to sweep dust and debris towards the suction port. Because the bristles are arranged radially and evenly distributed around the outside of the rotating disc, hair and other fibrous debris easily become entangled in them during cleaning. As cleaning time increases, more and more hair becomes entangled, not only reducing the cleaning efficiency of the side brush and preventing it from effectively sweeping dust and debris towards the suction port, thus affecting the overall cleaning effect of the vacuum cleaner; it also increases the rotational resistance of the side brush, leading to a greater load on the motor, consuming more energy, and shortening the vacuum cleaner's runtime. Furthermore, the entangled hair is difficult to remove, requiring users to spend a significant amount of time and effort manually removing it, causing considerable inconvenience.

[0005] Therefore, the inventors dedicated themselves to designing a side brush to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an anti-tangling external swing brush that can roll up and fling out hair during the cleaning process, thereby improving the anti-tangling effect, extending the robot vacuum's runtime, reducing the amount of manual hair removal work for users, and improving the user experience.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An anti-tangling outward-swinging side brush includes a housing, a rotating disk rotatably connected to the bottom of the housing, and multiple outward-swinging strips distributed radially along the side of the rotating disk. All the outward-swinging strips are concentrated on the same side of the rotating disk. Each outward-swinging strip is located outside the housing and faces the ground, and is spirally inclined along the rotation direction of the rotating disk. The free end of each outward-swinging strip is fixed with bristles along its axial direction.

[0009] As an improvement of the anti-tangling outer swing side brush of this utility model, the number of outer swing strips is two.

[0010] As an improvement of the anti-tangling outer swing brush of this utility model, a gear is rotatably connected inside the outer shell, and the gear is engaged with the rotating disk.

[0011] As an improvement of the anti-tangling outer swing brush of this utility model, the lower end face of the gear is provided with two snap-fit ​​arms spaced apart, and the upper end face of the rotating disk is provided with an insertion hole. The two snap-fit ​​arms pass through the outer shell and are inserted into the insertion hole, and both snap-fit ​​arms are snapped into the insertion hole.

[0012] As an improvement of the anti-tangling outer swing brush of this utility model, the two snap-fit ​​arms and the gear are integrally formed from the same material. The two corresponding sides of the insertion hole are respectively provided with slots, and the outer walls of the two snap-fit ​​arms are respectively provided with platforms. The two platforms and the two slots are engaged in a one-to-one correspondence.

[0013] As an improvement of the anti-tangling outward-swinging side brush of this utility model, the rotating disk includes a rotating bracket and a brush disk. The rotating bracket is located in the rotating groove at the bottom of the housing, the insertion hole is located at the top of the rotating bracket, the brush disk is located inside the rotating bracket, and all the outward-swinging strips are formed by extending from part of the side wall of the brush disk to the outside of the rotating bracket.

[0014] As an improvement of the anti-tangling outer swing brush of this utility model, all the outer swing strips and the brush plate are integrally formed from the same material. The top of the rotating bracket is provided with a groove, the groove is arranged around the insertion hole, the brush plate is located in the groove, and the groove is provided with a through hole for the outer swing strip to pass through.

[0015] As an improvement of the anti-tangling outward-swinging side brush of this utility model, the bottom of the groove is provided with multiple limiting holes, and the outer wall of the brush disk is provided with multiple limiting posts. All the limiting posts and all the limiting holes are matched one by one. The side plane of the rotating bracket is provided with a positioning platform. The positioning platform is in contact with the inner wall of the rotating groove to guide the rotating disk to rotate in the rotating groove.

[0016] As an improvement of the anti-tangling outward-swinging side brush of this utility model, the rotating disk further includes a connector. The rotating bracket is connected to the brush disk through the connector. The connector is located at the bottom of the rotating bracket and forms the bottom wall of the insertion hole. The bottom of the connector is exposed on the brush disk.

[0017] As an improvement of the anti-tangling outward-swinging side brush of this utility model, the hardness of the rotating bracket is greater than that of the brush disk, and the rotating bracket, the connecting piece and the brush disk are connected to form an integral structure through a secondary injection molding process.

[0018] Compared with existing technologies, the anti-tangling side brush of this utility model has multiple outward swing strips radially distributed on the side of the rotating disk, with all the outward swing strips concentrated on the same side of the rotating disk. Each outward swing strip is located outside the outer shell, facing the ground, and is spirally inclined along the rotation direction of the rotating disk. This causes the bristles to rotate spirally during the cleaning process, which helps to roll hair and other filamentous materials into loops according to the design. As the rotation continues, the rolled hair is continuously thrown off under the action of centrifugal force, thus effectively preventing hair from tangling on the bristles. This unique structural design not only significantly improves the cleaning efficiency of the side brush and reduces the problem of incomplete cleaning caused by hair tangling, but also reduces the load on the motor, extends the battery life of the sweeper, and greatly reduces the amount of manual hair removal work for users, providing users with a more convenient and efficient user experience.

[0037] Reference Figures 1 to 11 The working principle of the anti-tangling outward-swinging side brush of this utility model is as follows:

[0038] Motor 2 drives gear 3 to rotate via active gear or active gear set. The two locking arms 31 rotate with gear 3, which in turn drives the entire rotating disk 4 to rotate. The two bristle 8 rotate spirally with rotating disk 4, sweeping dust and debris in hard-to-reach areas such as corners and edges towards the vacuum port of the sweeper, thereby ensuring that the sweeper can achieve comprehensive and thorough cleaning.

[0039] This utility model's anti-tangling side brush features multiple outward swing strips 72 radially distributed on the side of the rotating disk 4, with all strips 72 concentrated on the same side of the rotating disk 4. Each outward swing strip 72 is located outside the outer shell 1, facing the ground and spirally inclined along the rotation direction of the rotating disk 4. This causes the bristle 8 to rotate spirally during cleaning, which helps to roll hair and other filamentous materials into loops according to the design. As the rotation continues, the rolled-up hair is continuously thrown off under the action of centrifugal force, effectively preventing hair from tangling on the bristle 8. This unique structural design not only significantly improves the cleaning efficiency of the side brush and reduces the problem of incomplete cleaning caused by hair tangling, but also reduces the load on the motor 2, extends the sweeper's runtime, and greatly reduces the amount of manual hair removal work for users, providing users with a more convenient and efficient user experience.

[0040] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
