Description

Automatic cleaning device for chalk eraser

Technical Field

The utility model relates to a chalk eraser self-cleaning device.

Background

The chalk eraser is also called a blackboard eraser, is used for erasing chalk characters on a blackboard and belongs to an indispensable cleaning tool in the teaching process. The prior blackboard eraser is generally made of materials such as flannelette and felt cloth. After the chalk is used for a period of time, the surface of the chalk needs to be cleaned manually, so that the subsequent use effect is ensured. In a general teaching process, a teacher can prepare 3-4 blackboard erasers for alternate use, and then intensively shoot off chalk dust on the surface after a period of time, so that the manual cleaning efficiency is low, the chalk dust can fly in the environment in the cleaning process, the environment is not protected, and hidden dangers can be brought to human health.

The purpose of the utility model is to realize through the following technical scheme:

the automatic cleaning device for the chalk eraser comprises a cleaning barrel body and a cleaning assembly arranged in the cleaning barrel body, wherein the cleaning assembly comprises a cleaning brush arranged at the center of the cleaning barrel body and a driving motor used for driving the cleaning brush to rotate, and a containing groove used for containing the chalk eraser is formed in the inner wall of the cleaning barrel body.

Preferably, the holding grooves are uniformly distributed on the inner wall of the cleaning cylinder in a staggered manner.

Preferably, a hollow separation plate is arranged in the cleaning barrel, and the cleaning brush is arranged above the separation plate.

Preferably, the partition plate is provided with an annular clamping groove, a containing barrel is detachably arranged in the annular clamping groove, and a containing groove is formed in the inner wall of the containing barrel.

Preferably, a notch is formed in the annular clamping groove, a protruding block matched with the notch is arranged on the outer wall of the bottom of the storage barrel, and the storage barrel is clamped and fixed with the notch through the protruding block.

Preferably, a dust suction assembly is arranged below the partition plate.

Preferably, the dust collection assembly is connected to a dust collection bag.

Preferably, the cleaning cylinder is further provided with a cylinder cover.

The beneficial effects of the utility model are that, can concentrate and clean the chalk eraser, and can effectual collection the chalk dust that drops, clean effectual, protected the environment, can also improve clean efficiency.

The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic structural diagram of the partition plate of the present invention.

Wherein, 1 clean barrel, 11 holding tanks, 2 cleaning brush, 3 division boards, 4 dust absorption subassemblies, 31 ring groove, 32 joint piece.

Detailed Description

The utility model discloses a chalk eraser self-cleaning device, as shown in the combined drawing 1, comprising a cleaning barrel body 1 and a cleaning component arranged in the cleaning barrel body 1. The cleaning assembly comprises a cleaning brush 2 arranged at the center of the cleaning barrel body and a driving motor (not shown in the figure) for driving the cleaning brush to rotate, and an accommodating groove 11 for accommodating a chalk eraser is formed in the inner wall of the cleaning barrel body 1. During the use, will treat that clear chalk eraser wipes into holding tank 11 in, will wipe chalk side to cleaning brush 2, start clean subassembly, cleaning brush 2 rotates, will drive the brush hair and carry out the striking off of chalk dust on chalk eraser surface, and the chalk dust after the striking off will fall into clean barrel 1. For better placing the chalk eraser, the accommodating grooves 11 are uniformly distributed on the inner wall of the cleaning barrel body 1 in a staggered manner.

Because chalk dust still can be dispersed in the barrel when cleaning, in order to avoid excessive scattering of chalk dust, be provided with fretwork division board 3 in the clean barrel 1, cleaning brush 2 is arranged in the top of division board 3. The dust collection component 4 is arranged below the partition plate 3, the dust collection component 4 is connected with a dust collection bag, the dust collection component 4 comprises a dust collection motor, a fan and the like, the dust collection purpose can be achieved by adopting the existing dust collection mode, and the dust collection principle is not repeated herein. When the cleaning brush is used for cleaning, the dust collection component 4 works to timely absorb and remove the chalk dust which is cleaned and scattered in the cleaning barrel body 1, so that dust is prevented from flying. Meanwhile, after a period of time, the dust collecting bag can be taken out from the bottom of the cleaning barrel 1 to intensively treat chalk dust. In order to cooperate with cleaning and dust collection, the cleaning cylinder body 1 is also provided with a cylinder body cover, and the cylinder body cover can cover the cleaning cylinder body 1 during cleaning.

As shown in the combined drawing 2, the distance between the cleaning brush 2 and the chalk eraser to be cleaned is matched conveniently and quickly, an annular clamping groove 31 is formed in the partition plate 3, a containing barrel is detachably clamped in the annular clamping groove 31, and the inner wall of the containing barrel is provided with a containing groove which is the same as the containing groove 11 and is used for placing the chalk eraser to be cleaned in the containing groove. Be provided with joint piece 32 in the ring groove 31, be provided with on the outer wall of containing bucket bottom with joint piece 32 assorted lug, during the connection, place the containing bucket in the ring groove 31, it is fixed to carry out the joint through lug and joint piece 32 after the rotation. The shape of the clamping block 32 can be various, preferably wedge-shaped, that is, one end of the clamping block 32 and the ring-shaped clamping groove 31 are transited to the other end through an arc.

Of course, the joint also can adopt and form the joint notch at ring groove 31 edge, the storage barrel bottom be provided with outward with joint notch assorted joint lug.

The utility model discloses an annular groove has been illustrated in the picture, also can set up a plurality of endocentric annular groove and corresponding storage bucket as required. If the distance between the cleaning brush and the chalk eraser is not adjusted in the mode of adjusting the containing barrel, the distance can be adjusted by adopting the cleaning brushes with different bristle lengths or different diameters.

The utility model has a plurality of specific implementation modes. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.
