Description

Ash-collecting blackboard eraser

Technical field

The utility model belongs to faceplate cleaning device technical field, is specifically related to a kind of blackboard eraser.

Background technology

As everyone knows, the main component of chalk is calcium sulfate, in the process erased the board, chalk dust flies upward everywhere, the wherein dust of particle less (diameter is at 10-20 μm), can suck via nose, be attached to mucous membrane small airway and alveolar, the meeting serious harm person's of erasing the board is healthy, also can endanger the health of people around simultaneously.

In order to alleviate or avoid the harm that chalk dust causes people, various circles of society have developed a series of products such as dust-free chalk, micronic dust chalk, new type blackboard, electric blackboard eraser.

As the blackboard eraser that can realize dust reduction capability that Chinese patent application 200810226800.X and 201210286967.1 provides, dust-proof for realizing, 200810226800.X the structural design of patent blackboard eraser is: comprise upper shell and lower house, the concave surface of upper shell is formed with the spatial accommodation holding water-absorbing sponge, be coated with wiper on the surface, the outward flange extension on the surface of upper shell is configured as connecting plate, the base plate of spatial accommodation is provided with inlet opening, inlet opening is provided with water fender, the back side of base plate is formed with connecting plate, lower house comprises surface, the outward flange on surface is provided with buckle, buckle is fastened on aforementioned connecting plate and is configured as closed dust collecting space, buckle is integrally formed with in addition in surface, buckle to be fastened on the connecting plate on base plate and to be configured as closed water storage space, close in water storage space and be provided with fore-set, fore-set one end is arc-shaped and props up water fender, be formed with button outside the surface that the other end of fore-set extends to lower house, roller is provided with between wiper and water-absorbing sponge, the two ends of roller are stretched out outside upper shell, upper shell is provided with the track holding roller, the side plate respective roller position of spatial accommodation is provided with dust inlet.The sealing of 201210286967.1 patent applications to its cavernous body water supply modes and water space is improved, and the structure of blackboard eraser is simplified more.These two patented technologies are by micro-wet blackboard eraser surface adhesion chalk dust, utilize water to realize solid dirt, dust-proof object.But there is following problem in these two patented technologies: 1, dust accumulation is difficult on wiper surface remove, and effectively can only remove chalk dust on wiper by changing clothes wiper frequently to realize; 2, with when being stained with the sponge brush blackboard of water, the place of nuzzling up at that time is very clean, but has part chalk dust to residue on blackboard, causes the blackboard after drying very colored like this; When 3, erasing the board, need to use the water outlet of external force extruding sponge ability, when external force is large not, the water in sponge will be caused not utilize completely and to remain in sponge; 4, the water due to sponge storage is more limited, so just needs could realize normally using blackboard eraser by adding water frequently.

The and for example multinomial patented technology such as Chinese patent application 200920165876.6,201020531776.3,201120564276.4,201220340776.4 and 201320158277.8, all to reduce for the purpose of the flying upward of the dust in process of erasing the board, provide the blackboard eraser of various functional structure form.Such as 201120564276.4, denomination of invention is the patent application of " ash-collecting blackboard eraser ", and its blackboard eraser comprises hollow structure blackboard eraser, and blackboard eraser bottom surface is provided with felt hair, and blackboard eraser is provided with air suction opening in the middle part of bottom surface; The blackboard eraser back side is provided with battery case; Blackboard eraser inner chamber is provided with dust absorption fan, and dust absorption fan is connected to the blackboard eraser back side, and covering of the fan is just to blackboard eraser bottom surface, and dust absorption fan is connected with battery case by switch; Between dust absorption fan and blackboard eraser bottom surface, be provided with baffle plate, baffle plate and blackboard eraser left surface, right flank, downside are completely closed to be connected, and leaves ventilating opening between upper side; Baffle plate and blackboard eraser bottom surface form dust accommodating chamber, and dust accommodating chamber lower end is provided with dust export; The nearly back side, blackboard eraser downside place is provided with exhaust outlet, and exhaust outlet is provided with detachable filter screen.All the other patented technologies are all and are provided with dust collect plant in blackboard erasers.But this type of patented technology also exists following problem or deficiency: 1, because dust granules is less, can suspend and flow together with air in atmosphere, therefore utilize baffle plate dust can not be isolated from dust accommodating chamber, and exhaust outlet can be flowed to; 2, because dust granules is less, even if exhaust outlet is provided with detachable filter screen, a part of dust also can be diffused in air through filter screen; 3, after having cleaned, this blackboard eraser can only keep upright state, once be kept flat, then the dust sucked in blackboard eraser will be flowed out by the air suction opening in the middle part of blackboard eraser bottom surface; 4, due to the restriction of its structure, this blackboard eraser can only be used for the clean panel erect, and range of application is limited; 5, because dust export size is less and be positioned at the below of dust, even if dust accumulates in accommodating chamber, also should not discharge from dust export.

In sum, prior art not can solve the problem of dust pollution in the process of erasing the board, and needs badly and provides a kind of dust-proof effect better blackboard eraser.
