Description
Technical field
The utility model belongs to educational supply field, especially relates to a kind of Chalk-dust suction rod.
Background technology
Along with the progress in epoch, some electronics are given lessons and be instead of traditional writing on the blackboard and give lessons, but completely not universal, and especially for remote districts, teacher and classmates also endure the torment of chalk powder to the fullest extent.Chalk powder can have a strong impact on the respiratory system of people, but for teachers in order to the responsibility discharging oneself has to bear such danger.
Utility model content
The purpose of this utility model is to provide a kind of Chalk-dust suction rod, effectively can absorb chalk powder and avoid it to fly upward everywhere.
The technical solution of the utility model is: Chalk-dust suction rod, comprise absorption cell and power box, described absorption cell front end is provided with air inlet, described absorption cell lower end is provided with handle, connect absorption cell place in described power box and be provided with screening film, be provided with motor and fan in described power box, described power box end is provided with gas outlet.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, handle is provided with in absorption cell lower end, handle can be arrested safe and reliable during use, in power box, be provided with screening film effectively can filter out chalk powder, not only reach the effect of dust suction but also do not damage engine and fan, be provided with air inlet and gas outlet in front and back end respectively, ensure that the circulation of gas in order to avoid difference is suppressed in generation cause danger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1, absorption cell 2, power box 3, air inlet
4, handle 5, screening film 6, motor
7, fan 8, gas outlet
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, the utility model Chalk-dust suction rod, comprise absorption cell 1 and power box 2, described absorption cell 1 front end is provided with air inlet 3, described absorption cell 1 lower end is provided with handle 4, connect absorption cell 1 place in described power box 2 and be provided with screening film 5, be provided with motor 6 and fan 7 in described power box 2, described power box 2 end is provided with venthole 8.
The course of work of this example: when write word on blackboard after or when needing to erase the board, open Chalk-dust suction rod, motor and fan will work, aim to inhale place, chalk powder will enter absorption cell along with gas, and clean gas finally can flow out from gas outlet again.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
