Summary of the invention
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, provides a kind of structure simple, easy to use, a kind of dust absorption blackboard eraser that pick-up performance is good.
The purpose of this utility model is achieved through the following technical solutions:
A kind of dust absorption blackboard eraser, comprise plate body, the pars intermedia of described plate body is provided with sucker, the upper end of plate body is provided with air bag, and the lower end of plate body is provided with brushing, and the pars intermedia of described plate body is provided with slot hole, the openend in slot hole is positioned at the side of plate body, slot is provided with sealing plug-in board in hole, and the upper end of described air bag is provided with exhaust outlet, and exhaust ports is provided with sealing plug.
Described sucker is made up of upper sucker and lower sucker, and described upper sucker is positioned at the top of plate body interpolation slotted eye, and described lower sucker is positioned at the bottom of plate body interpolation slotted eye, and the vertical center line of described upper sucker and lower sucker overlaps.
The utility model has the advantages that: the utility model is that the negative pressure by producing after pressing air bags carries out suction dust, and dust can not spray after sucking again, makes dust be stored in air bag, is outwelled by exhaust outlet again, can not cause environmental pollution again like this.Therefore, the utility model has and structure is simple, easy to use, the features such as pick-up performance is good, with low cost.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Detailed description of the invention
Embodiment: dust absorption blackboard eraser as shown in the figure, comprise plate body 8, the pars intermedia of described plate body 8 is provided with sucker, the upper end of plate body 8 is provided with air bag 2, and the lower end of plate body 8 is provided with brushing 6, and the pars intermedia of described plate body 8 is provided with slot hole 4, the openend in slot hole 4 is positioned at the side of plate body 8, be provided with sealing plug-in board 5 in slot hole 8, the upper end of described air bag 2 is provided with exhaust outlet 1, and exhaust outlet 1 place is provided with sealing plug 9.
Described sucker is made up of upper sucker 3 and lower sucker 7, and described upper sucker 3 is positioned at the top of plate body 8 interpolation slotted eye 4, and described lower sucker 7 is positioned at the bottom of plate body 8 interpolation slotted eye 4, and described upper sucker 3 overlaps with the vertical center line of lower sucker 7.
The utility model in use, blackboard eraser is placed on blackboard, the sealing plug 9 at exhaust outlet 1 place is opened, by pressuring gasbag 2, the air in air bag 2 is discharged by exhaust outlet 1, then covering sealing plug 9, then the plate 5 in slot hole 4 is extracted, now be in negative pressure state in air bag 2, extracting plate 5 out can suck in air bag 2 by dust, and air bag 2 just can slowly restPose in the process, reaches the object of dust suction with this.Be inserted in slot hole 4 by plate 5 after wiping blackboard again and seal, object is to not allow dust discharge from upper sucker 3 and lower sucker 7, opening the stopper 9 at exhaust outlet 1 place, outwelled by dust by exhaust outlet 1.
