Description

Technical Field

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

[0002] In daily life, people have increasingly higher requirements for a clean environment, especially in home cleaning, where thorough cleaning of the interior of the house is necessary. Traditional cleaning tools, such as brooms, are not only ineffective at cleaning but also time-consuming and laborious. Therefore, vacuum cleaners, which offer better cleaning capabilities and higher efficiency, are being used more and more widely. Ordinary vacuum cleaners have a good collection and cleaning function for debris and particles through strong suction. However, when it comes to hair (especially long hair), it is very easy for long hair to get tangled in the vacuum cleaner's floor brush after being sucked into the vacuum cleaner, making the floor brush difficult to clean and potentially causing the vacuum cleaner to malfunction. Utility Model Content

[0003] The purpose of this invention is to provide a vacuum cleaner head with a roller brush. This vacuum cleaner head with a roller brush can achieve reciprocating drive of the moving blade within a limited housing space, and cut and decompose the hair before negative pressure suction, effectively avoiding the situation where long hair gets tangled and causes the roller to jam, thus improving the cleaning effect and user experience.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vacuum cleaner head with a roller brush, comprising: a vacuum cleaner housing having a vacuum chamber and an air inlet respectively, a roller brush rotatably disposed in the vacuum chamber, and a drive assembly connected to one end of the roller brush. The roller brush further comprises: a cylindrical housing extending along the length direction of the vacuum cleaner housing and connected to the drive assembly, and a movable blade and a stationary blade each extending along the axial direction of the cylindrical housing. A blade hole is provided on the side wall of the cylindrical housing to cooperate with the movable blade and the stationary blade. The movable blade and the stationary blade stacked in the cylindrical housing each have a plurality of blade teeth that are spaced apart along their length direction and pass through the blade holes. The blade teeth of the stationary blade fixedly installed on the cylindrical housing and the blade teeth of the movable blade that can reciprocate along the axial direction of the cylindrical housing are staggered in their length direction. The cylindrical housing is provided with a reciprocating screw extending along its axial direction. One end of the reciprocating screw is mounted on the cylindrical housing through at least two spaced bearings, extending to the outside of one end of the cylindrical housing and engaging with the dust collection housing through a flat part. One end of a slider that engages with the reciprocating screw is embedded in the helical groove of the reciprocating screw, and the other end of the slider is connected to the moving blade through a movable seat, for driving the moving blade to reciprocate along the axial direction of the cylindrical housing.

[0005] The following are further improvements to the above technical solution: 1. In the above solution, the main body of the moving blade has a connecting part that mates with the movable seat on the side opposite to its toothed part. The connecting part is embedded in the movable seat and connected to the movable seat through at least one set of mating pins and pin holes.

[0006] 2. In the above scheme, a guide post extending along the axial direction of the cylindrical shell is installed inside the cylindrical shell and on both sides of the slider, and a guide hole that slides with the guide post is opened on the movable seat.

[0007] 3. In the above scheme, the cutting teeth of both the moving blade and the stationary blade are trapezoidal cutting teeth.

[0008] 4. In the above scheme, both opposite sides of the blade tooth are set as cutting edges.

[0009] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model of a dust collection device has a blade hole on the side wall of its cylindrical shell, which mates with a moving blade and a stationary blade. Each of the moving and stationary blades, stacked inside the cylindrical shell, has several teeth spaced along its length and extending through the blade hole. The teeth of the stationary blade, fixedly mounted on the cylindrical shell, and the teeth of the moving blade, which can reciprocate axially along the cylindrical shell, are staggered along their length. A reciprocating screw extending axially is installed inside the cylindrical shell, and the reciprocating screw is mounted on the cylindrical shell via at least two spaced bearings. One end extends to the outside of one end of the cylindrical housing and engages with the vacuum housing through a flat part. One end of a slider that engages with a reciprocating screw is embedded in the spiral groove of the reciprocating screw, and the other end of the slider is connected to the moving blade through a movable seat. This is used to drive the moving blade to reciprocate along the axial direction of the cylindrical housing. This allows for the reciprocating drive of the moving blade within the limited housing space. Furthermore, through the cooperation of the moving and stationary blades, the hair is cut and decomposed before being suctioned by negative pressure, effectively preventing long hair from getting tangled and causing the roller to jam, thus improving the cleaning effect and user experience.

A bristle strip or brush (not shown in the figure) can be provided on the outside of the cylindrical shell 61 to avoid the movable blade 62 and stationary blade 63, which rotate with the roller brush 6, from contacting and colliding with the ground during the rotation of the roller brush 6, and to prevent the parts of the movable blade 62 and stationary blade 63 that extend out of the cylindrical shell 61 from being damaged.

[0019] Two support bearings 76 are provided; the cylindrical housing 61 of the roller brush 6 is a plastic housing formed by splicing together at least two injection molded parts.

[0020] A reciprocating lead screw is a precision component that achieves mechanical transmission through a helical groove structure. Its core feature is that when the main shaft rotates in one direction, it drives the slider to complete axial reciprocating motion. It can be obtained by purchasing and falls within the scope of existing technology, so it will not be elaborated here.

[0021] Working principle: During use, the cylindrical shell of the roller brush is driven to rotate by the drive component, which simultaneously creates negative pressure to suck out the dust particles in the dust collection chamber through the air inlet. As the cylindrical shell of the roller brush rotates, it drives the moving and stationary blades and the slider that works with the reciprocating screw to rotate as well. This causes the slider to move along the spiral groove on the reciprocating screw, which remains stationary relative to the dust collection housing. This drives the moving blade to move back and forth along the axial direction of the cylindrical shell while rotating. The moving and stationary blades work together to cut the hair that is wrapped between adjacent blades, cutting long hair into small segments that are easy to be sucked out by negative pressure, thus preventing the roller from jamming due to long hair tangling.

[0022] When using the aforementioned vacuum cleaner head with a roller brush, the moving blades can be reciprocated within a limited housing space. Furthermore, through the cooperation of the moving and stationary blades, the hair is cut and decomposed before being sucked up by negative pressure, effectively preventing long hair from getting tangled and causing the roller to jam, thus improving the cleaning effect and user experience.

[0023] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
