With the dust removal part arranged, the blackboard eraser can absorb the dust caused by cleaning the blackboard, thus protecting the environment and ensuring the health of users.
Description
Technical field
The utility model relates to a kind of blackboard eraser, is specifically related to a kind of blackboard eraser of automatic dust absorption.
Background technology
At present, existing blackboard eraser is used for occasions such as teaching, meeting in a large number, is made up of a plate body and the fine hair cloth that is installed on the plate body, its shortcoming is that existing blackboard eraser can produce a large amount of dust in wiping process, contaminated environment if sucked by the user, then influences user's health.
The utility model content
The utility model provides a kind of blackboard eraser of automatic dust absorption, can siphon away the dust that the blackboard wiping process produces, and the protection environment is good for health.
For achieving the above object, the technical solution of the utility model is as follows, a kind of blackboard eraser of automatic dust absorption, it is characterized in that, this blackboard eraser comprises main element, is arranged on the wiper member on this main element one side, and the dedusting parts that are arranged on this main element inside.
Above-mentioned main element comprises shell and the top cover that is arranged on the shell; This top cover is arranged on the one side that is not provided with wiper member.
Above-mentioned shell, its one side that is provided with wiper member is provided with air inlet openings; The side of this shell is provided with the opening of giving vent to anger.
Above-mentioned dedusting parts comprise dust extractor, and the filter dirt module and the switch block that are connected with this dust extractor; The position of the corresponding above-mentioned air inlet openings of the air inlet of this dust extractor is provided with.
After starting the utility model, when wiper member was removed chalk writing, dust extractor saw through wiper member and draws the dust that is caused by the wiping chalk, and fed filter dirt module.The dust that enters filter dirt module is adsorbed by dirt filtrating screen, and bag dust filter is collected the dust that is adsorbed delay.The process filtered air enters atmosphere by the gas outlet of dedusting parts.
The blackboard eraser of a kind of automatic dust absorption of the utility model is compared with existing blackboard eraser, and its advantage is that the utility model is provided with the dedusting parts, can draw because the black caused dust of meal of wiping, and the protection environment guarantees that the user's is healthy.
Description of drawings
Fig. 1 is the structural representation of the blackboard eraser of a kind of automatic dust absorption of the utility model.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the blackboard eraser of a kind of automatic dust absorption that the utility model provides, this blackboard eraser comprises main element 1, is arranged on the wiper member 2 on this main element 1 one side, and the dedusting parts 3 that are arranged on this main element 1 inside.
Dedusting parts 3 adopt the mini dust catcher of the SC-H24 of Sanyo type, and dedusting parts 3 comprise dust extractor 31, filter dirt module and switch block 32.Dust extractor 31 adopts electric exhaust fan, this electric exhaust fan can produce extremely strong suction and pressure with the rotating speed of per second 500 circles, under the effect of suction and pressure, air is discharged at a high speed, and the air of dust extractor 31 front ends constantly replenishes the air in the dust extractor 31, cause dedusting parts 3 inner instantaneous vacuum and the external atmosphere pressure formation negative pressure of producing, make air and dust be inhaled into dedusting parts 3.
The area of the openings of sizes of the air inlet of this dust extractor 31 and wiper member 2 is complementary, to guarantee more fully dedusting; This dust extractor 31 adopts No. 7 batteries of two joints to provide stabilized power source for it, need not externally fed, and this battery is installed in dedusting parts 3 inside.These dust extractor 31 circuit are connected with switch block 32 simultaneously, can freely control the startup of dust extractor 31 and close.Filter dirt module is arranged on dedusting parts 3 inside, and is connected with dust extractor 31, and this filter dirt module comprises dirt filtrating screen and bag dust filter.Filter dirt module also connects the gas outlet of dedusting parts 3, and this gas outlet discharging is via filter dirt module filtered air.
Workflow of the present utility model is as follows;
After the blackboard eraser of a kind of automatic dust absorption of the utility model started by switch block 32, in wiper member 2 wiping chalk writings, dust extractor 31 saw through wiper member 2 and draws the dust that is caused by the wiping chalk, and fed filter dirt module.The dust that enters filter dirt module is adsorbed by dirt filtrating screen, and bag dust filter is collected the dust that is adsorbed delay.The process filtered air enters atmosphere by the gas outlet of dedusting parts 3, just can remove the pollution of dust to environment thus.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection domain of the present utility model should be limited to the appended claims.
