Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a floor scrubber gearbox with an anti-hair entanglement structure. Background Technology

[0002] Among the core components of a floor scrubber, the gearbox plays a crucial role. It drives the scrubber's roller brush to rotate, thereby achieving efficient cleaning of stains and dust on the floor. The gearbox has now become a standard core component in various household and commercial floor scrubbers, supporting the machine's basic cleaning functions.

[0003] However, in everyday cleaning scenarios, hair scattered on the floor is always an unavoidable problem. In a home environment, hair easily falls out with activity; in households with pets, pet hair during molting season will adhere to the floor and carpet crevices; commercial or factory environments also have various kinds of synthetic fibers. When the floor scrubber is working, this hair will be drawn into the equipment as the roller brush rotates, and if it is not stopped in time, it will gradually enter the gearbox.

[0004] Once hair gets inside the gearbox, it will cause multiple problems. On the one hand, hair will get tangled in the motor shaft, gear meshing, and bearing surfaces, creating additional resistance. This will significantly reduce power transmission efficiency, slow down the roller brush rotation, and make it difficult to handle stains and hair that were originally easy to clean, directly reducing the cleaning effect of the floor scrubber. On the other hand, long-term accumulation of hair can cause parts to jam, which will not only accelerate the wear of gear teeth and bearings, but may also cause motor overload due to excessive resistance. This can lead to the machine shutting down due to protection mechanisms, or even burning out the motor and damaging the gearbox, significantly shortening the overall lifespan of the floor scrubber and bringing additional maintenance costs to the user.

[0005] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0006] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, one objective of the present invention is to provide a floor scrubber gearbox with an anti-hair entanglement structure, which can effectively prevent hair from entering the gearbox.

[0010] In some embodiments, the roller brush connector has an outer groove on its outer periphery and an inner groove on its inner periphery, the ball bearing is sleeved in the inner groove, and the rubber washer is secured in the outer groove.

[0011] In some embodiments, the inner slot is longer than the outer slot, and a groove is provided at the bottom connection of the outer slot and the inner slot. The anti-hair entanglement structure also includes a hair groove structure, which is disposed on the base plate. The hair groove structure is disposed at the front end of the base plate and is adapted to the groove. The outer side of the hair groove structure is recessed to form a hair groove to restrict the movement of hair. The hair groove structure cooperates with the roller brush to prevent hair from entering the gearbox assembly.

[0012] In some embodiments, a mounting portion adapted to the bottom end of the inner slot is provided on the base plate and inside the hair groove structure. The mounting portion is stair-shaped and includes a first step, a second step, and a third step. The third step is connected to the bottom end of the ball bearing, and the first step is connected to the bottom end of the inner slot.

Detailed Implementation

[0019] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0020] like Figures 1 to 5 As shown, this embodiment provides a floor scrubber gearbox with an anti-hair entanglement structure, including a roller brush 1, a gearbox assembly 2, a fan blade 3, and a base plate 4. The gearbox assembly 2 is disposed inside the roller brush 1. A rotating shaft 21 is provided at the front end of the gearbox assembly 2, and the rotating shaft 21 is connected to the fan blade 3. The gearbox assembly 2 is connected to the roller brush 1 through the fan blade 3. The rear end of the gearbox assembly 2 is connected to the base plate 4. The gearbox assembly 2 includes a motor 22, and an anti-hair entanglement structure 5 is provided at the connection between the rear end of the motor 22, the rear end of the roller brush 1 and the base plate 4.

[0021] This invention proposes a floor scrubber gearbox with an anti-hair entanglement structure, which can effectively prevent hair from entering the gearbox, not only extending the service life of the floor scrubber gearbox, but also reducing the difficulty and cost of daily maintenance for users, and greatly improving cleaning efficiency and user experience.

[0022] Specifically, a motor base 23 is provided at the rear end of the motor 22, and a tail bearing seat 231 extends rearward from the middle of the motor base 23. The anti-hair entanglement structure 5 includes a roller brush connecting assembly 6, which is sleeved on the outer periphery of the tail bearing seat 231. The roller brush connecting assembly 6 is located between the motor base 23, the roller brush 1, and the base plate 4. The arrangement of the roller brush connecting assembly 6 forms a sealed structure between the motor base 23, the roller brush 1, and the base plate 4, preventing hair and foreign objects from entering the motor 22.

[0023] Furthermore, the roller brush connecting assembly 6 includes a ball bearing 61, a roller brush connector 62, and a rubber washer 63. The ball bearing 61 is sleeved on the outer periphery of the tail bearing seat 231. The roller brush connector 62 is disposed between the ball bearing 61 and the roller brush 1. The rubber washer 63 is disposed on the outer periphery of the roller brush connector 62 to increase the friction between the roller brush 1 and the roller brush connector 62. The tail bearing seat 231 provides support.

[0024] Preferably, the roller brush connector 62 has an outer retaining groove 621 on its outer periphery and an inner retaining groove 622 on its inner periphery. The ball bearing 61 is fitted into the inner retaining groove 622, and the rubber washer 63 is secured in the outer retaining groove 621. The outer retaining groove 621 and the inner retaining groove 622 make the installation of the ball bearing 61 and the rubber washer 63 more secure.

[0025] Specifically, the inner slot 622 is longer than the outer slot 621. A groove 623 is provided at the bottom connection between the outer slot 621 and the inner slot 622. The anti-hair entanglement structure 5 also includes a hair groove structure 41, which is disposed on the base plate 4. The hair groove structure 41 is located at the front end of the base plate 4 and is adapted to the groove 623. The outer side of the hair groove structure 41 is recessed to form a hair groove 42 to restrict the movement of hair. The hair groove structure 41 cooperates with the roller brush 1 to prevent hair from entering the gearbox assembly 2. The hair groove structure 41 can collect the hair that accumulates during the cleaning process, which not only makes it convenient for users to clean the hair but also prevents hair from entering the gearbox assembly 2.

[0026] Furthermore, a mounting part 43 adapted to the bottom end of the inner slot 622 is provided on the base plate 4 and inside the hair groove structure 41. The mounting part 43 is stair-shaped, including a first step 431, a second step 432, and a third step 433. The third step 433 is connected to the bottom end of the ball bearing 61, and the first step 431 is connected to the bottom end of the inner slot 622. When the base plate 4 and the roller brush connector 62 are assembled, the mounting part 43, the roller brush connector 62, and the ball bearing 61 form a labyrinth structure. The labyrinth structure effectively prevents hair from entering the interior of the floor scrubber gearbox and avoids hair from getting tangled on the ball bearing 61.

[0027] Furthermore, the gearbox assembly 2 also includes a positive wiring harness 24 and a negative wiring harness 25. The positive wiring harness 24 and the negative wiring harness 25 are connected to the rear end of the motor 22. A wire outlet hole 44 is provided on the base plate 4. One end of the positive wiring harness 24 and the negative wiring harness 25 is electrically connected to the motor 22, and the other end passes through the wire outlet hole 44 and is connected to the power supply. The wire outlet hole 44 allows the positive wiring harness 24 and the negative wiring harness 25 to be neatly arranged.

[0028] Furthermore, the outer periphery of the roller brush 1 is provided with several spiral patterns 11. The spiral pattern of the roller brush 1 creates a directional spiral airflow and mechanical scraping force when it rotates, resulting in stronger cleaning ability compared to a smooth roller brush. It can clean the gaps between floor tiles and achieves better cleaning results. In addition, the manufacturer can adjust the depth and density of the spiral patterns 11 as needed to adapt to different application scenarios.

[0029] Furthermore, the base plate 4 is made of metal. The metal material makes the base plate 4 more supportive. The above descriptions are only some embodiments of this utility model. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
