Abstract

The utility model relates to a product cleaning device, and particularly relates to a blackboard eraser cleaner for cleaning dust on blackboard erasers. The blackboard eraser cleaner comprises an airtight cavity, a rotating shaft, a screen mesh and a dust storing container; and the blackboard eraser cleaner is characterized in that the cavity is hollow and airtight, an opening at the top of the cavity is used for placing a blackboard eraser, an opening at the lower part of the cavity is used as a dust outlet connected with the dust storing container, the two ends of the rotating shaft are horizontally fixed on the inner wall of the cavity, one end of the rotating shaft penetrates the inner wall of the cavity so as to connect with external power, and the screen mesh is fixed on the rotating shaft. According to the blackboard eraser cleaner provided by the utility model, the rotating shaft and the screen mesh are driven to rotate through the external power, and the screen mesh just oversweeps bristles of a blackboard eraser, so that chalk dust on the bristles falls, and because an airtight cavity is designed for limiting dust in the airtight cavity, harm to the physical health of the human body due to a situation that dust pollutes the surrounding environment and a situation that dust is inhaled into the human body is avoided.

Description

Eraser cleaner

Technical field

The utility model relates to the cleaning device of product, relates in particular to a kind of for removing the eraser cleaner of blackboard eraser dust.

Background technology

Traditional blackboard eraser and chalk coordinate for the use of the occasions such as classroom instruction, training, lecture, increase along with the blackboard eraser access times, the effect of wiping of blackboard eraser weakens gradually, in order to recover the dust ability of wiping of blackboard eraser, traditional method is to beat blackboard eraser, by vibrations, makes dust break away from the bristle of blackboard eraser, but, this way can cause chalk dust to diffuse to surrounding environment, contaminated air, and the people sucks dust and can cause damage to healthy.

Therefore, there is defect in prior art, needs further improvement and development.

Summary of the invention

The purpose of this utility model is to provide a kind of cleaner that can clean blackboard eraser, and this cleaner has airtight cavity, and the dust after guaranteeing to clean constrains in the zone of sealing, avoids contaminated environment, harm end user's health.

To achieve these goals, the utility model adopts following technical scheme:

Eraser cleaner, comprise airtight cavity, rotating shaft, silk screen and dust storing containers, wherein, cavity hollow and airtight, the open top of cavity is for placing blackboard eraser, and the cavity lower openings connects the dust storing containers as dust-exhausting port, and the both ends horizontal of rotating shaft is fixed on cavity inner wall, and wherein an end penetrates to connect external impetus from cavity inner wall, and silk screen is fixed in rotating shaft.

Described eraser cleaner, wherein, cavity open top shape is consistent with blackboard eraser, the blackboard eraser body is stuck in opening part, the bristle of blackboard eraser stretches out from the cavity inside top, when the described silk screen be fixed in rotating shaft rotates with rotating shaft, and the bristle of the good inswept blackboard eraser in silk screen edge.

Described eraser cleaner, wherein, described silk screen by pasting, outer embedding or the mode that is bumped into be fixed on described rotating shaft axostylus axostyle.

Described eraser cleaner, wherein, ramped bottom surface is equipped with in the bottom of described cavity, and incline direction points to the dust-exhausting port direction.

The eraser cleaner that the utility model provides, drive rotating shaft and silk screen rotation by external connection power, silk screen is the bristle of inswept blackboard eraser just, the chalk dust that makes to stick on bristle drops, owing to having designed airtight cavity, dust is strapped in the space of sealing, avoid the dust pollution surrounding environment, avoid human body to suck dust, cause damage to healthy.

The structural representation that Fig. 1 is the external motor power of the utility model eraser cleaner;

The structural representation that Fig. 2 is the external manual power of the utility model eraser cleaner;

The schematic diagram that Fig. 3 is the utility model operation principle.

The specific embodiment

Below in conjunction with preferred embodiment, the utility model is described in further details.

Eraser cleaner of the present utility model comprises eraser cleaner cavity 110, rotating shaft 120, silk screen 130 and dust storing containers 140; As shown in Figure 1, opening 111 is arranged at the top of described blackboard eraser cleaning chamber device cavity 110, and dedusting mouth 113 is arranged at bottom, and ramped bottom surface 112 has been installed in the bottom of eraser cleaner cavity 110, and incline direction points to dedusting mouth 113; Rotating shaft 120 comprises axostylus axostyle 121, axostylus axostyle 121 is fixed on eraser cleaner cavity 110 inwalls by two fixed blocks 122, and an end of axostylus axostyle 121 penetrates from cavity 110 inwalls, silk screen 130 is fixed on axostylus axostyle 121, and described silk screen is connected and fixed with described rotating shaft axostylus axostyle by stickup, outer embedding, the mode imbedding or be bumped into.Dedusting mouth 113 be connected dust storing containers 140 docking.

Eraser cleaner of the present utility model, the profile of its opening 110 is consistent with blackboard eraser 100, as shown in Figure 3, when putting into opening 110, blackboard eraser 100 can not drop, the bristle 101 of blackboard eraser 100 extend into the cavity inboard, when rotating shaft axostylus axostyle 121 rotates, and the bristle 101 of silk screen 130 inswept blackboard erasers.Rotating shaft axostylus axostyle 121 is through the inwall of blackboard eraser cavity 110, external connection power device; During due to work, dust is limited in airtight cavity always, can not cause the dust diffuse pollution.

First preferred embodiment of described eraser cleaner, described dust storing containers can be set to cuboid 140, and described external connection power can be set to be connected with the motor 150 of power supply 151, and the airtight cavity open top is set to 3, can clean 3 blackboard erasers, as shown in Figure 1 simultaneously.

Second preferred embodiment of described eraser cleaner, described dust storing containers can be set to sack 170, and described external connection power can be set to handle 160, and the airtight cavity open top is set to 2, can clean 2 blackboard erasers, as shown in Figure 2 simultaneously.

The shape of described eraser cleaner cavity 110 and dust storing containers does not limit, and the form of external connection power does not limit.

Above content is the explanation to preferred embodiment of the present utility model, can help those skilled in the art to understand more fully the technical solution of the utility model.But these embodiment only illustrate, can not assert that the specific embodiment of the present utility model only limits to the explanation of these embodiment.Concerning the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deductions and conversion, all should be considered as belonging to protection domain of the present utility model.
