Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner floor brushes, and more specifically to a roller brush quick-release mechanism and a floor cleaning device. Background Art

[0002] In the field of floor cleaning, the assembly design of the roller brush structure is crucial because it is directly related to the cleaning effect and ease of use. In the current general design, the roller brush assembly and the floor brush assembly are usually locked by a locking assembly to ensure a firm connection between the components to ensure the normal operation of the cleaning equipment. However, when disassembling the roller brush assembly, the user must first unlock the locking assembly and then manually pull out the roller brush assembly. This operation process is relatively cumbersome and inconvenient, and during the manual extraction process, the fingers are likely to touch the surface of the roller brush, causing inconvenience in operation and potential hygiene problems. Summary of the invention

[0003] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model proposes a roller brush quick-release mechanism, where the user only needs to turn the lock buckle to switch it from a locked state to an unlocked state, release the elastic potential energy stored in the spring, and pop open the rotating seat to easily remove the roller brush assembly, which greatly improves the usability and maintenance efficiency of the cleaning equipment, reduces the tediousness of user operations, reduces the possibility of users accidentally touching the roller brush surface, and improves hygiene and safety.

[0004] The utility model also provides a floor cleaning device with the roller brush quick-release mechanism.

[0005] The technical solution adopted by the utility model is to provide a roller brush quick-release mechanism, comprising:

[0006] A floor brush body, wherein a driving assembly is provided inside;

[0007] A roller brush having a transmission end for connecting to an output end of the drive assembly;

[0008] A rotating seat, one end of the roller brush away from the transmission end is rotatably connected to the rotating seat;

[0009] A lock is provided between the rotating seat and the floor brush body, and the floor brush body is provided with a release spring block acting on the rotating seat, and the release spring block has an elastic tendency to make the rotating seat move away from the floor brush body. When the lock is unlocked, the release spring block pops out the rotating seat.

[0010] After adopting the above structure, the user only needs to turn the lock to switch it from the locked state to the unlocked state. After that, the release spring loses the restrictive effect brought by the lock, and its own stored elastic potential energy is released, which pops the rotating seat open and releases it. The rotating seat drives one end of the roller brush to tilt up, so that the user can easily remove the roller brush assembly from the floor brush body without too much manual operation. This design greatly improves the ease of use and maintenance efficiency of the cleaning equipment, not only reduces the tediousness of user operations, but also reduces the possibility of users accidentally touching the roller brush surface, thereby improving hygiene and safety.

[0011] According to an embodiment of the utility model, the rotating seat has a protrusion extending outward along the axial direction of the roller brush, and the release spring block acts on the protrusion; that is, the protrusion serves as a force-bearing structure on the rotating seat and abuts against the release spring block.

[0012] According to an embodiment of the utility model, the release spring block is elastically mounted on the floor brush body via a spring; the spring compresses and reserves the elastic potential energy of the release spring block.

[0013] According to an embodiment of the present invention, the release spring block is a columnar structure made of elastic material; the columnar structure is bent or folded to store the elastic potential energy of the release spring.

[0014] According to an embodiment of the utility model, the floor brush body is provided with a lateral locking hole, and the lock buckle has an inserting tongue for inserting into the locking hole.

[0015] According to an embodiment of the present invention, the lock has an operating portion, and the operating portion is exposed outwardly relative to the surface of the rotating seat.

[0016] According to an embodiment of the utility model, the end of the roller brush away from the transmission end is a connecting end, and a bearing is provided between the connecting end and the rotating seat.

[0017] A floor cleaning device comprises any one of the above-mentioned roller brush quick-release mechanisms. BRIEF DESCRIPTION OF THE DRAWINGS
