Description
Technical field
The utility model relates to classroom chalk dust process field, particularly relates to a kind of blackboard and takes out dirt system.
Background technology
In classroom, on blackboard, the injury of chalk dust to Faculty and Students is not effectively solved for a long time.Although micronic dust chalk is universal, when blackboard eraser erasing, still have a large amount of dust and produce, cause serious dust pollution at blackboard local location.For this reason, need a kind of equipment, namely can easily be integrated on new blackboard, the dust pelletizing system can transformed old blackboard again, system needs to have the features such as easy to use, cheap, convenient installation.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of blackboard and takes out dirt modifying system, not only solves the problem that blackboard chalk dust pollutes, also has easy to use, cheap, conveniently install, is convenient to the advantages such as expansion.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of blackboard is with taking out dirt system, include blackboard eraser, blackboard eraser is connected with negative pressure source by pipeline, the dust bag collecting dust and the blackboard eraser described in gauge tap controlling negative pressure source work are split-type design, comprise blackboard eraser main part and blackboard eraser hairbrush portion, blackboard eraser hairbrush is provided with passage bottom portion, also detachable strainer is provided with between blackboard eraser main part and blackboard eraser hairbrush portion, connecting pipe between described blackboard eraser and negative pressure source is Telescopic pipeline, described negative pressure source and dust bag are integrated in a casing, the bottom of this casing is provided with the air exhauster as negative pressure source, the top of air exhauster is provided with dust bag, dust bag is communicated with by connector with described Telescopic pipeline.
The beneficial effects of the utility model are: dirt modifying system taken out by a kind of blackboard of the utility model, has easy to use, cheap, conveniently installs, is convenient to the advantages such as expansion, easy large-scale promotion.

Wherein: blower fan of 1, bleeding, 2, dust bag, 3, telescopic pipes, 4, blackboard eraser, 5, switch, 6, casing, 41, blackboard eraser main part, 42, blackboard eraser hairbrush portion, 43, passage, 44, detachable strainer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model preferred embodiment is described in detail, to make the advantage of utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the utility model embodiment comprises: a kind of blackboard is with taking out dirt system, include blackboard eraser (4), blackboard eraser is connected with the blower fan of bleeding (1) as negative pressure source by telescopic pipes (3), and described blower fan of bleeding (1) and dust bag (2) are integrated in a casing (6).Open blower fan of bleeding (1) power supply by switch (5), blower fan work is bled.Telescopic pipes (3) connects the interface on blackboard eraser (4).The negative pressure that blower fan produces acts on blackboard eraser (4) around by telescopic pipes (3).Chalk dust under hairbrush brush is sucked into telescopic pipes after filter screen, finally concentrates in grey bag (2).
Blackboard eraser (4) described as shown in Figure 2 comprises blackboard eraser main part and blackboard eraser hairbrush portion, and blackboard eraser hairbrush is provided with passage bottom portion, between blackboard eraser main part and blackboard eraser hairbrush portion, be also provided with detachable strainer, the orifice telescopic pipes of blackboard eraser main part.
Described blower fan of bleeding adopts quiet blower fan, effectively reduces noise;
The grey bag of described collection can use throwing type, also rear recycling capable of washing;
Described telescopic pipes is accommodated in when not using in fixture, can extract, do not block blackboard when use;
Described dust bag is communicated with by connector with described Telescopic pipeline, and described connector is bayonet connection or is threaded connector.
Described gauge tap is arranged on blackboard eraser or is arranged on casing.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
