Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning devices, in particular to a robot cleaning device. Background Art

[0002] The robot is mainly used for cleaning the ground, which can save manpower to a certain extent. The robot cleaning device is one of the main components of the robot. The robot cleaning device mainly includes a body c, on which two brush rods are arranged, and the brush rods are provided with large bristles. The body is provided with a straight rod near the brush rod, such as Figure 1 As shown, brush teeth b are arranged on the straight rod a. The brush teeth b are in a straight line shape and can contact with the large bristles to a certain extent. When working, the brush teeth can clean the hair on the large bristles to a certain extent.

[0003] A robot cleaning device similar to the above technical solution in the prior art was found to have room for improvement during actual implementation: the brush teeth are straight, so the hooking and pulling force for the hair entangled on the large bristles is insufficient, which easily causes the hair on the large bristles to be unable to be pulled off. Utility Model Content

[0004] In view of the shortcomings and defects in the prior art, the purpose of the utility model is to provide a robot cleaning device, which solves the problem that the brush teeth of the robot cleaning device in the prior art have insufficient hooking force on the hair entangled on the large bristles.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a robot cleaning device, comprising a brush rod rotatably arranged on a robot body, the brush rod being provided with large bristles, and also comprising a straight rod, the straight rod being provided with brush teeth, the ends of the brush teeth being provided with hooks, the brush teeth being provided with a plurality of serrations, a slide groove being provided on the body, a slider being provided slidingly in the slide groove, a rotating sleeve being rotatably arranged on the slider, the rotating sleeve being detachably and liftably connected to the straight rod, a first dust suction port being provided on the body above the large bristles, a second dust suction port being provided at the bottom of the body near the outside, and the second dust suction port being connected to a soft suction tube extending outward.

[0006] As a further improvement of the utility model, the bottom of the sliding block is connected to the rotating sleeve via a motor.

[0007] As a further improvement of the utility model, the straight rod can be inserted into the rotating sleeve in a manner that it can be adjusted up and down, and is locked with a locking bolt.

[0008] As a further improvement of the utility model, a plurality of small bristles are provided at the bottom of the brush rod.

[0009] As a further improvement of the present invention, a third dust suction port is provided at the bottom of the brush rod.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. By providing a hook at the end of the brush tooth and a plurality of saw teeth on the rod of the brush tooth, when the brush tooth and the bristles rotate, the hook and saw teeth on the rotating brush tooth can easily cut or hook off the bristles, greatly enhancing the removal force and hooking force of the entangled hair on the bristles, thereby facilitating the removal of the hair on the bristles.

[0012] In addition, a slide groove is provided on the machine body, which is slidably connected to a slider, and a rotating sleeve is rotatably provided on the slider, and the rotating sleeve is detachably and liftably connected to the straight rod, so that the brush teeth can be relatively slidably adjusted on the machine body, so the position distance of the brush teeth relative to the bristles and the height of the brush teeth can be conveniently adjusted according to the different lengths of the hair, which is more flexible and convenient; in addition, the straight rod is detachably connected to the rotating sleeve, so it is convenient to disassemble and replace the straight rod and the brush teeth.
