Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum cleaner technology, and more specifically, to an anti-collision vacuum cleaner floor brush. Background Technology
[0002] The floor brush of a vacuum cleaner is a rotating brush head at the bottom of the vacuum cleaner, mainly used for cleaning hard surfaces such as carpets and floors. Existing vacuum cleaner floor brushes are equipped with anti-collision devices at the front end to reduce damage to walls and furniture in the user's home when the vacuum cleaner collides with other parts during vacuuming.
[0003] Existing anti-collision devices mainly use adhesive bonding to fix flexible anti-collision strips (e.g., felt strips) to the front end of the vacuum cleaner's floor brush, reducing collision damage through the elasticity of the flexible anti-collision strips themselves.
[0004] However, due to the limited elastic buffering performance of the flexible bumper strips, they fail to achieve a good buffering effect when a collision occurs.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-collision vacuum cleaner floor brush to solve the above-mentioned problems.
[0007] This utility model achieves the above objectives through the following technical solution: an anti-collision vacuum cleaner floor brush, comprising:
[0008] The floor brush body has rollers rotatably mounted on it to reduce frictional resistance when the floor brush slides.
[0009] A bumper strip is slidably mounted on the main body of the floor brush. An elastic element is abutting between the main body of the floor brush and the bumper strip so that when the bumper strip is not in contact with other objects, one end of the bumper strip protrudes from the surface of the main body of the floor brush.
[0010] A braking assembly is installed on the main body of the floor brush. The two ends of the braking assembly are connected to the anti-collision strip and the roller, so that when the anti-collision strip comes into contact with other objects and causes inward displacement, the braking assembly applies an external force to the roller to prevent rotation.
[0011] The present invention is further configured such that the braking assembly includes:
[0012] A braking element is used to abut against the roller. The braking element is slidably disposed inside the main body of the floor brush. One end of the anti-collision strip is connected to the braking element.
[0013] The second elastic element is used to push the brake away from the roller, and the two ends of the second elastic element abut against the brake and the main body of the floor brush, respectively.
[0014] When the anti-collision strip is displaced inward, it pushes the braking component to overcome the elastic force of the elastic element and move towards the roller.
[0015] The present invention is further configured such that: the anti-collision strip has an embedded part at one end facing the brake member, the brake member is slidably connected to the embedded part, and the mating surfaces of the embedded part and the brake member are both inclined.
[0016] The present invention is further configured such that: a through groove is provided on the anti-collision strip, and a positioning rod for embedding into the through groove is detachably connected to the main body of the floor brush;
[0017] The positioning rod is used to limit the sliding direction of the anti-collision strip along the main body of the floor brush so that the braking component is triggered when the anti-collision strip moves inward.
[0018] The present invention is further configured such that: a rubber strip is fixedly connected to the anti-collision strip, and the rubber strip is located at one end of the anti-collision strip that protrudes from the surface of the brush body.
[0019] The present invention is further configured such that the side wall of the brake component used to fit the roller is configured as an arc-shaped surface structure, and anti-slip texture is provided on the arc-shaped surface.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] Firstly, by combining the anti-collision strips with elastic elements, a dual shock absorption effect of "physical buffer space + elastic force buffer" is formed, which significantly reduces the impact force during collision and effectively protects the main body and internal components of the floor brush.
[0022] Secondly, through the transmission between the embedded part of the anti-collision strip and the inclined surface of the brake component, the horizontal displacement of the anti-collision strip is converted into the vertical displacement of the brake component, which pushes the brake component to overcome the elastic force of the elastic element and abut against the roller, realizing the instantaneous response of "collision trigger - automatic braking", quickly slowing down the moving speed of the floor brush and further reducing the collision energy.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. Example
[0030] Anti-collision vacuum cleaner floor brush, such as Figures 1-5 As shown, the device includes a floor brush body 1, a bumper strip 2 slidably mounted on the floor brush body 1, and a braking assembly mounted on the floor brush body 1. An elastic element 3 is abutting between the floor brush body 1 and the bumper strip 2. When the bumper strip 2 is not in contact with other objects, one end of the bumper strip 2 protrudes from the surface of the floor brush body 1. Thus, in the event of a collision, the elastic element 3 provides a better shock absorption effect, and the protrusion from the surface of the floor brush body 1 increases the space where the bumper strip 2 can retract, thereby further improving the shock absorption effect and better protecting the vacuum cleaner's floor brush.
[0031] At the same time, such as Figure 4 As shown, the main body 1 of the floor brush is rotatably equipped with rollers to reduce frictional resistance when the floor brush slides. The two ends of the braking assembly are connected to the anti-collision strip 2 and the rollers. When the anti-collision strip 2 comes into contact with other objects and forms an inward displacement, the anti-collision strip 2 applies an external force to the braking assembly. The braking assembly applies an external force to the rollers to hinder their rotation, thereby slowing down the rotation speed of the rollers and reducing the impact force formed during a collision, thus achieving a better protective effect.
[0032] like Figures 3-5As shown, the braking assembly includes a brake element 4 for contacting the roller and an elastic element 5 for pushing the brake element 4 away from the roller. The two ends of the elastic element 5 abut against the brake element 4 and the floor brush body 1, respectively. Through the elastic support of the elastic element 5, the brake element 4 is normally separated from the roller, ensuring normal operation of the roller. The brake element 4 is slidably disposed inside the floor brush body 1. One end of the anti-collision strip 2 is connected to the brake element 4, so that when the anti-collision strip 2 moves inward, it pushes the brake element 4 against the elastic force of the elastic element 5, moving it closer to the roller, thus achieving a braking effect on the roller.
[0033] like Figures 2-3 As shown, the anti-collision strip 2 has an embedded part at one end facing the brake member 4. The brake member 4 is slidably connected to the embedded part, and the mating surfaces of the embedded part and the brake member 4 are both inclined. When the anti-collision strip 2 moves inward through the inclined mating surfaces, it forms a downward thrust on the brake member 4, ensuring the braking effect on the roller.
[0034] At the same time, such as Figure 4 As shown, the brake component 4 is designed with an arc-shaped surface structure for its side wall to fit against the roller. The arc-shaped surface structure allows the brake component 4 to stably fit against the outer surface of the roller, and anti-slip textures are provided on the arc-shaped surface to enhance the resistance effect.
[0035] like Figures 3-4 As shown, the anti-collision strip 2 has a through groove 7, and a positioning rod 6 for embedding into the through groove 7 is detachably connected to the floor brush body 1. The positioning rod 6 is used to limit the sliding direction of the anti-collision strip 2 along the floor brush body 1, so that the braking component can be stably triggered when the anti-collision strip 2 moves inward, ensuring the transmission stability between them. At the same time, the positioning rod 6 also limits the displacement range of the anti-collision strip 2, thereby preventing the anti-collision strip 2 from over-travel, which would cause the anti-collision strip 2 to fall off or be damaged in its internal structure.
[0036] Among them, such as Figure 3 As shown, the positioning rod 6 is fixed to the floor brush body 1 by a threaded connection. The floor brush body 1 is provided with a screw hole. The tail of the positioning rod 6 is machined with an M4 external thread, and the head is provided with an internal hexagonal groove. It can be disassembled by an internal hexagonal wrench, thereby realizing the disassembly and connection between the floor brush body 1 and the positioning rod 6.
[0037] like Figures 1-5 As shown, a rubber strip 8 is fixedly connected to the anti-collision strip 2. The rubber strip 8 is located at one end of the anti-collision strip 2 that protrudes from the surface of the brush body 1. The rubber strip 8 enhances the shock absorption and buffering effect of the anti-collision strip 2 surface.
[0038] Both elastic element 3 and elastic element 5 are made of cylindrical helical springs. The brush body 1 and the anti-collision strip 2 are fixedly connected to the elastic element 3 at the connection points, and the brake element 4 and the brush body 1 are fixedly connected to the elastic element 5 at the connection points. The guide posts are embedded inside the elastic element 3 and elastic element 5 to enhance the firmness of the connection. There is a gap between the guide post and the cylindrical helical spring to ensure the normal use of the cylindrical helical spring.
[0039] Working principle: When the anti-collision strip 2 collides with an obstacle, it first increases the retraction space through the protruding structure, and works with the elastic element 3 to compress and buffer the impact; at the same time, the horizontal displacement of the anti-collision strip 2 is converted into the vertical displacement of the braking element 4 through the inclined surface, pushing the braking element 4 to overcome the elastic force of the elastic element 5 and abut against the roller, and increasing the frictional resistance through the anti-slip texture, so as to achieve dual protection of 'buffering + braking', which can better reduce the impact force of collision than the traditional buffer structure.
[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
