Description
The utility model relates to a kind of blackboard eraser, especially a kind of ash-collecting blackboard eraser.
At present, it mainly is hand that the existing blackboard for education of China is wiped, and dust from flying during wiping makes a big impact to the Faculty and Students of the work of being engaged in teaching for a long time, and pollutes classroom environment.Someone has designed a kind of electric dust absorption blackboard eraser, and a motor is arranged in blackboard eraser, forms negative pressure during running dust is sucked in the blackboard eraser, removes then.This blackboard eraser has two shortcomings, and the one, its dust containing capacity is too little, and every wiping once need be removed once, otherwise dust will hold after the dirt chamber fills up too much, make no longer dust suction.The 2nd, heavier, very tired during use because motor is positioned at blackboard eraser, especially the pupil uses inconveniently especially, therefore fails fine popularization to come.Other has a kind of automatic dust-absorbing blackboard to wipe; be on blackboard, to be provided with track; blackboard eraser can move back and forth along track the blackboard writing is wiped, and simultaneously dust is sucked blackboard brush, and this blackboard eraser cost is higher; during installation track need be arranged; very trouble is then inapplicable for the place of some teaching condition differences, and its use occasion simultaneously also is restricted; only limit to blackboard fixing in the classroom and use, the blackboard often movable for needs then can not use.
As long as the purpose of this utility model is to provide a kind of power supply that has, can in all case use, and easy to operate ash-collecting blackboard eraser, the blower fan of this blackboard eraser can be installed in outside window.
The utility model is realized in the following manner, ash-collecting blackboard eraser, and it is made up of blower fan, dust cleaning case and suction nozzle three parts; Be connected by pipeline between blower fan and dust cleaning case, dust cleaning case and the suction nozzle; Dust cleaning case comprises dust storage chamber, clean room, pallet; Be provided with filter course and air entry and exhaust outlet in the clean room, have between dust storage chamber and the clean room between a blade, blade and the pallet to be connected, near the pallet place one stage clip is arranged at trace by a trace.
On dust cleaning case, the air entry place of clean room is provided with a check sheet.
Between pallet and filter course, be provided with a vibrating spring.
Pipeline between dust cleaning case and the suction nozzle is a flexible pipe.
Dust cleaning case is provided with power switch.
Can produce following good effect after adopting this combination: 1, dust can be absorbed effectively, purify the air of a room; 2, the safe ready that operates only needs hand-held suction nozzle wiping to get final product; 3, since blower fan be installed in outside window, can be because of the peace and quiet in the noise effect classroom that produces; 4, durable in use, long service life.
Be described in further details below in conjunction with drawings and the specific embodiments.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model suction box;
Fig. 3 is the structural representation of the utility model suction nozzle.
As seen from Figure 1, whole ash-collecting blackboard eraser is made up of three parts, and blower fan 1 can adopt axial-flow type or centrifugal small-sized fan, be installed in the classroom outside window or outdoor other place; Dust cleaning case 2 is positioned at the classroom, can be placed on one jiao at dais, classroom, be connected by pipeline 4 between blower fan 1 and the dust cleaning case 2, pipeline 4 can adopt the hard pipeline of metal material, also can adopt flexible pipe to connect, link together with the exhaust outlet 7 on the dust cleaning case 2, dust cleaning case 2 comprises dust storage chamber 10 and clean room 8 and pallet 17, as shown in Figure 2, in purification 8, be located at filter course 15, filter course 15 is positioned at the below of exhaust outlet 7, and a blade 9 is arranged between dust storage chamber 10 and the clean room 8, and blade 9 one ends are for being movably hinged; Pallet 17 is positioned at the top of dust cleaning case 2, link to each other by a trace 12 between blade 9 and the pallet 17, near pallet 17 places one stage clip 18 is arranged at trace 12, when closing switch 11, after being placed into suction nozzle 3 on the pallet 17, pallet 17 is depressed, blade 9 is opened, in the dust landing dust storage chamber 10, between pallet and filter course 15, also has a vibrating spring 16, after pallet 17 is depressed, vibrating spring 16 drives filter course 15 vibrations, the dust that is adsorbed on the filter course 15 is shaken, enter in the dust storage chamber of opening simultaneously 10, prevent to stop up filter course 15; Another kind of mode is not establish vibrating spring 16, and is provided with a slot on the surface of dust cleaning case 2, regularly inserts with thin bar and beats filter course 15, and dust is shaken.Dust storage chamber 10 need regularly be opened, and removes the dust of the inside, and will there be a check sheet 14 at air entry 13 places on dust cleaning case 2, prevent the dust reverse flow: be connected by flexible pipe 5 between dust cleaning case 2 and the suction nozzle 3, because it is movable that suction nozzle 3 needs back and forth, therefore, pipeline must adopt flexible pipe, in the suction nozzle 3 is cavity, front end has hairbrush 6, and hole 20 is arranged between the hairbrush 6, links to each other with cavity 19 in the suction nozzle 3, as shown in Figure 3, hairbrush 3 can adopt cotton, hair etc. to make; Power switch 11 is arranged on the dust cleaning case 2, also can be arranged on the suction nozzle 3, can also be arranged on other position, and the set-up mode of these several switches all belongs to the technical solution of the utility model.
During use, hand-held suction nozzle 3 turns on the power switch 11, the beginning wiping, and blower fan 1 rotates simultaneously, and chalk is sucked in the dust cleaning case 2, and dust enters in the dust storage chamber 10 after filtration, and the air after the filtration is discharged into outdoor along exhaust outlet 7 by blower fan 1.
