Rotary cleaning device at the bottom of the vacuum cleaner

The invention relates to a cleaning device for a bottom of a vacuum cleaner, in particular to a rotary cleaning device which is easy to disassemble, can be flexibly arranged, transmits through a linkage transmission and can reduce the power load.

The first job of floor cleaning is to carry out the cleaning operation first. The traditional cleaning is manually cleaned with a broom, or it can be wiped one by one with a rag. However, both of them consume a lot of physical strength and time. Although the vacuum cleaner can be used for vacuuming, the conventional vacuum cleaner must also be manually held. Operational movement, time cost is still inevitable.

In order to improve the efficiency of the front cleaning work, some people have developed an automatic cleaning machine with a vacuum function, which uses the machine to move the dust at the bottom of the machine, or can be equipped with a bristles tool to sweep the bristles. The operation mode of the conventional cleaning machine is mainly driven by a built-in motor to rotate a rotating disc. The periphery of the rotating disc extends a plurality of bundle brushes, which are mostly made of nylon material. When the rotating disc rotates, the bundles are The brush touches the ground for cleaning and polishing, but the effect is not good and it is easy to scratch the floor material. In addition, each rotating disk needs to be pivotally connected to the rotating motor inside the cleaning machine, and is separately rotated by the power provided by the corresponding motor. In other words, if two rotating disks are arranged at the bottom, there must be two internal motors, which are not only large Increased assembly and production costs, more damage to the excessive power of the cleaning machine, and excessive power transmission devices increase the risk of failure. In addition, the movement of the conventional automatic cleaning machine is achieved by the rollers provided on the left and right sides of the bottom, and the rotating disk is arranged in front of the roller. However, since the traveling direction of the cleaning machine is not necessarily, the front and the rear are backward, and the roller is traveling. It may adhere to dust and adhere to the ground. The rotating disc placed in front of the roller cannot effectively clean the dirt generated by the roller during the process. In view of this, how to make the cleaning component of the cleaning machine easy to clean and replace, and the structure is stable, the structure is simple, and the cleaning device with the least power output is an urgent problem to be solved by the practitioners.
