Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a vacuum cleaner brush head. Background Technology

[0002] Vacuum cleaners are highly efficient cleaning tools, primarily used for cleaning dust from floors, carpets, and other surfaces. With technological advancements, people's demands for vacuum cleaners have continuously increased. As a result, various vacuum cleaner brush heads have been invented to work with vacuum cleaners. Vacuum cleaners are no longer limited to sucking up dust, hair, and other dirt; they can also extract and remove mites and their excrement, providing convenience for daily cleaning. However, most vacuum cleaner brush heads on the market currently use synchronous belt drives, which not only have low transmission efficiency but also require dedicated space to house the synchronous belt and drive motor, making the vacuum cleaner brush head structure bulky and taking up a lot of space.

[0003] For the reasons mentioned above, it is necessary to improve the existing technology. Utility Model Content

[0009] It also includes a rotating roller, which is rotatably disposed in the housing and has a spiral protrusion protruding therein;

[0010] The driving device includes a drive motor disposed in the inner cavity of the rotating roller, a gear sleeved on one end of the drive motor, and a rotating head sleeved on the gear at one end. The other end of the rotating head is recessed with a groove that cooperates with the protrusion, and the inner wall of the rotating head sleeved on the gear is protruded with teeth that mesh with the gear.

[0011] In the above technical solution, a protective shell is fixedly installed on the outside of the housing.

[0012] In the above technical solution, pulleys are rotatably provided on both sides of the bottom of the housing.

[0013] In the above technical solution, the bottom of the housing is provided with mite-removing brush strips that extend laterally to both ends of the housing.

[0014] In the above technical solution, the connecting joint is hinged to one side of the housing, and auxiliary wheels are rotatably provided at both ends of the joint.

[0015] III. Beneficial Effects

[0016] Compared with the prior art, the present invention has the following advantages: setting the drive device in the rotating roller can optimize the structure of the vacuum cleaner brush head and reduce the space occupied by the vacuum cleaner brush head. At the same time, using gear drive instead of synchronous belt drive can increase transmission efficiency and improve load-bearing capacity. Attached Figure Description

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0023] Please see Figure 1-4 This utility model provides a vacuum cleaner brush head, including a housing 1, wherein a suction port 10 is provided on one side of the housing 1;

[0024] Connecting connector 2, the connecting connector 2 is disposed on one side of the housing 1, and its inner cavity is provided with a suction pipe 20 communicating with the suction port 10;

[0025] It also includes a rotating roller 3, which is rotatably disposed in the housing 1 and has a spiral protrusion 30 protruding therein;

[0026] The driving device 4 includes a driving motor 40 disposed in the inner cavity of the rotating roller 3, a gear 41 sleeved on one end of the driving motor 40, and a rotating head 42 sleeved on the gear 41 at one end. The other end of the rotating head 42 is recessed with a groove 43 that cooperates with the protrusion 30, and the inner wall of the rotating head 42 sleeved on the gear 41 is provided with teeth 44 that mesh with the gear 41.

[0027] In the above structure, after the drive motor is started, it drives the gear set on one side to rotate. The gear meshes with the teeth of the rotating head, causing the gear to drive the rotating head to rotate synchronously. At the same time, the groove on the other side of the rotating head cooperates with the protrusion of the rotating roller, causing the rotating roller to be driven by the rotating head to rotate synchronously. The overall structure sets the drive device in the internal cavity of the rotating roller, reducing the usable area of ​​the overall structure. At the same time, the meshing gear as a transmission device can increase the transmission efficiency and improve the load-bearing capacity, ensuring that the vacuum cleaner brush head can still operate stably when encountering resistance such as carpets and hair.

[0028] Specifically, a protective shell 11 is fixedly provided on the outside of the housing 1. The protective shell is used to protect the housing and prevent the housing from being damaged.

[0029] Specifically, pulleys 12 are rotatably provided on both sides of the bottom of the housing 1. The pulleys can assist the vacuum cleaner brush head to roll along the ground when it is used, preventing the bottom of the vacuum cleaner brush head from being directly rubbed and damaged by the ground.

[0030] Specifically, the bottom of the housing 1 is provided with mite-removing brush strips 13 that extend laterally to both ends of the housing 1. The mite-removing brush strips mainly enhance the adsorption capacity of the vacuum cleaner and help the vacuum cleaner brush head remove mites and their excrement more effectively.

[0031] Specifically, the connecting joint 2 is hinged to one side of the housing 1, and auxiliary wheels 14 are rotatably provided at both ends of it. The auxiliary wheels play a role in balancing and supporting, ensuring that the vacuum cleaner brush head maintains stable operation during the movement process.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
