Specific embodiment
The invention will be further described in the following with reference to the drawings and specific embodiments.It should be noted that following institute
Involved technical characteristic can be combined with each other as long as they do not conflict with each other in each embodiment of the present invention of description.
Embodiment one：
Disclosed is a kind of multifunctional blackboard eraser, as shown in Figure 1：
A kind of multifunctional blackboard eraser, including blackboard eraser body 1, the outline border 2 being arranged in parallel with blackboard 3, the blackboard eraser body 1
It is nested between outline border 2 and blackboard 3, blackboard eraser body 1 is influenced to move between outline border 2 and blackboard 3 by external force, blackboard eraser
Plastics or metal material package sponge cloth preferably may be used in ontology 1 or bristle is made, as shown in figure 4, blackboard eraser body 1
It is rectangular shape；The outline border material alfer or aluminum material；The 1 symmetrical support of lower section setting two of blackboard eraser body
The blackboard eraser body 1 of frame 4, the supporting rack 4 and metal either plastics is made into integration or is stuck in blackboard eraser by 4 top of supporting rack
In ontology 1, supporting rack 4 is linked together by one flat plate 5, and tablet 5 supports two supporting racks 4；There is an air pressure in 5 lower section of tablet
There are a cylinder in lifting gear 6, the lower section of pressure liftable device 6, and the piston air-leg in cylinder, which moves up and down to dominate, to be lifted, and is generally adopted
It is filled with nitrogen, generally more than 99%, pressure is connected to adjust concentration in one or two atm higher, pressure liftable device 6
Handle 7 when pressing regulation handle 7, does not give lifting shaft external force, and lifting shaft is bound to peak at once, speed, at this time blackboard
It wipes ontology 1 to move upwards under the action of supporting rack 3, realizes the function of erasing the board, do not press（Or the midway pressed is unclamped）It adjusts
When handle 7：Lifting shaft remains in current location, and compression and stretching cannot all be such that it is moved relative to outer sleeve；Blackboard eraser
A thin bar 10 is also connected in the middle part of ontology, thin bar 10 is connected as a single entity with blackboard eraser body 1, when blackboard eraser body 1 is in air pressure liter
When falling unit 6 is bound to peak, by pinning regulation handle 7 while pulling thin bar 10, blackboard eraser body 1 is slow under external force
Slowly drop to minimum point, then decontrol regulation handle 7, blackboard eraser body returns to origin, and realization once erases the board back and forth；It is described black
There is a square orifice 8 on 1 left side of blackboard eraser ontology, and square orifice 8 is coupled underneath dust exhaust apparatus 9, dust exhaust apparatus 9 using vertical type dust collector or
Horizontal dust collector uses telescopic soft tube at the connector 91 of dust exhaust apparatus 9；Blackboard eraser body lower part is also installed by powder slot
12,12 side of powder slot is provided with baffle 121, which can prevent chalk dust from falling on the ground, and sweeps trouble, baffle
121 be that powder flies out from both sides in order to prevent；The outer arch of the present invention is also comprising a headlamp 13, when darkness needs light
When, it can realize that night gives lessons by headlamp 13.
The present invention specifically used method be：
Fig. 1 is the original state before the use of the present invention, when needing to erase the board, first, by the connector 91 of vertical type dust collector
The square orifice on 1 left side of blackboard eraser body is connected, is turned on the switch, starts dust suction；By pressing regulation handle 7, pressure liftable device 6
Tablet 5 is headed on, tablet 5 pushes 4 fast upward motion of supporting rack, and state diagram is as shown in figure 3, realize the primary mistake to erase the board upwards
Journey unclamps regulation handle 7 to top automatically.When blackboard eraser body 1 is pulled down, by pressing regulation handle 7 while drawing
Dynamic thin bar 10, since external force acts on, blackboard eraser body 1 returns to original position, at this moment unclamps regulation handle 7, and blackboard eraser body 1 is just fixed
In situ, vertical type dust collector power supply is closed, realizes the process once to erase the board.
Embodiment two：
As shown in Fig. 2, compared with embodiment one, cleaning device 11, cleaning device 11 is coupled underneath in the square orifice of embodiment two
It is made of the squeeze bottle with detergent 111, the function that embodiment two is realized is to clean blackboard, is squeezed by squeeze bottle, is cleaned
Agent 111 can be entered in the sponge cloth or bristle of blackboard eraser by square orifice 8, at this moment pass through Pneumatic power elevator apparatus 6 and thin bar
About 10 movement is realized and cleans blackboard, efficient and convenient.
The application method of embodiment two is：When need cleaning blackboard when, first, cleaning device 11 is connected into square orifice 8, squeeze
Cleaning device 11 is pressed, detergent 111 can be entered by square orifice 8 in blackboard eraser body 1, at this moment can detach cleaning device 11,
Square orifice 8 is sealed simultaneously, by pressing regulation handle 7, pressure liftable device 6 heads on tablet 5, and tablet 5 pushes supporting rack 4 quick
It moves upwards, realizes the primary process for cleaning blackboard upwards, unclamp regulation handle 7 automatically to top.When blackboard eraser body 1
When pulling down, by pressing regulation handle 7 while pulling thin bar 10, since external force acts on, blackboard eraser body 1 returns to original position, this
Shi Songkai regulation handles 7, blackboard eraser body 1 are secured to original position.
The present invention realizes that blackboard eraser body quickly moves up and down, operation side by the combination of Pneumatic power elevator apparatus and thin bar
Just, it is simple in structure；Dust automatic absorption process of aggregation can be realized by dust exhaust apparatus and cleaning device and clean the function of blackboard,
Manpower is saved, prevents dust from sucking human body, ensures health.
The above described is only a preferred embodiment of the present invention, be not intended to limit the scope of the present invention,
Therefore the variation or modification that claim under this invention and specification are done in every case, it should all belong to the range that patent of the present invention covers
Within.
