Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Fig. 1 ~ Fig. 5, the utility model provides a kind of dust suction environment-friendly dust-proof eraser, and it comprises inverted L shape shell 1, protecgulum 2, battery cabin cap 3, upper cover 4, wiping felt 5, entering-dust mouth 6, blackboard eraser hair 7, dust absorption fan 8, battery compartment 9, tortuous passageway 10, dust collection storehouse 11 and filter screen 12.
Shell 1 front portion is provided with protecgulum 2, and rear portion is provided with battery cabin cap 3, and top is provided with upper cover 4.Protecgulum 2 middle position is provided with two parallel wiping felts 5, be positioned at wiping felt 5 periphery and be provided with entering-dust mouth 6, entering-dust mouth 6 periphery is provided with blackboard eraser hair 7, primarily of wiping felt 5, letter written with chalk is wiped from blackboard when erasing the board, then the chalk dust atomization of wiping being piled up by blackboard eraser hair 7.As shown in Figure 3, in shell 1, the shell 1 being positioned at the short brink of falling L is provided with dust absorption fan 8, the two phase flow that the chalk dust of atomization and air are formed can be sucked in shell 1 by entering-dust mouth 6 after starting dust absorption fan 8.The shell 1 being positioned at the long side of falling L is provided with battery compartment 9, installs the battery that promising dust absorption fan 8 is powered, for convenience detachly can exchange battery (as shown in Figure 1, Figure 3) for by battery cabin cap 3 in battery compartment 9; Battery compartment 9 rear portion is provided with tortuous passageway 10, and the entrance of tortuous passageway 10 is communicated with entering-dust mouth 6.Be positioned at below battery compartment 9 and be provided with dust collection storehouse 11, the import in dust collection storehouse 11 and an outlet of tortuous passageway 10; Another outlet of tortuous passageway 10 is communicated with the space of installing dust absorption fan 8, and this connectivity part is provided with filter screen 12, for being filtered by the chalk dust of collection and finally making chalk dust fall in dust collection storehouse 11.
In above-described embodiment, as Figure 1 and Figure 4, protecgulum 2 and upper cover 4 are all fixed on shell 1 by attachment screw 13, and protecgulum 2 and shell 1 junction are provided with shaping packing seal 14, to ensure only having entering-dust mouth 6 one air inlets, and then increase the pick-up performance of dust absorption fan 8.Packing seal 14 can adopt O type rubber ring etc.When wiping felt 5 and blackboard eraser hair 7 wearing and tearing can not normally use, dismounting and change can be carried out by attachment screw 13.Upper cover 4 can be opened by attachment screw 13, can take out dust absorption fan 8 after opening, and carries out cleaning to dust absorption fan 8 and filter screen 12.
In the various embodiments described above, as shown in Figure 3, bottom dust collection storehouse 11, be provided with dust discharge plug 15, when chalk ash collection to certain many time, dust discharge plug 15 can be opened chalk dust is focused on.
In the various embodiments described above, as shown in Figure 1, shown in Figure 5, upper cover 4 is provided with exhaust outlet 16, discharges in shell 1 for the gas that dust absorption fan 8 is sucked.
In the various embodiments described above, as shown in Figure 1 and Figure 2, be positioned on the sidewall of shell 1 side and be provided with for controlling battery operated switch 17.
In sum, the utility model in use, first takes off battery cabin cap 3, is built by battery cabin cap 3 again, open switch 17 after loading battery, and dust absorption fan 8 just starts to rotate.Letter written with chalk on now erasing the board, letter written with chalk just can be wiped under the wiping action of wiping felt 5, after the chalk dust that accumulation produces is atomized by the outer field blackboard eraser hair 7 of blackboard eraser further, under the suction of dust absorption fan 8, the Dual-Phrase Distribution of Gas olid having chalk dust and air to be formed just is sucked tortuous passageway 10 by from entering-dust mouth 6, and after tortuous passageway 10 exports and filtered by filter screen 12, gas is discharged by exhaust outlet 16, and chalk dust is filtered net 12 filters.After blackboard wipes, closing switch 17, dust absorption fan 8 stops operating, and the chalk dust filtered then is fallen in dust collection storehouse 11.Due to the sealing function of tortuous passageway 10, no matter how blackboard eraser puts upside down inclination, and the chalk dust gathered all can not be spilt.When chalk ash collection to certain many time, dust discharge plug 15 can be opened and chalk dust is poured out focus on.
The various embodiments described above are only for illustration of the utility model; the connection of each parts and structure all can change to some extent; on the basis of technical solutions of the utility model; all improvement of carrying out the connection of individual part and structure according to the utility model principle and equivalents, all should not get rid of outside protection domain of the present utility model.
