Abstract

The utility model relates to a novel dustless blackboard eraser, which consists of a suction slit, an opening cover, a hinge, a micro-vacuum cleaner, a battery, a circuit, an electric shock apparatus, a rubbing skin, and a board body. The vacuum cleaner is designed in the technical proposal, so the utility model can conveniently collect dust; and the opening cover is design in the technical proposal, so the utility model is easy for removing dust, and handling. The blackboard eraser is characterized in that: the electric shock apparatus is arranged at the lower part of the board body; the micro-vacuum cleaner and the battery are arranged in the board body. Therefore, the utility model has an application value very much.

Description

The new no-dust blackboard eraser

(1) technical field:

The utility model relates to the new no-dust blackboard eraser.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance; The big class of office appliance is write or drawing article, the assistant product group of writing or draw, and big group of the cleaning device of blackboard or slabstone has the little technical group field of sucking chalk powder device.

(2) background technology:

At present, have now and big group of the cleaning device that once had, have the technology of the group of sucking chalk powder device that the demand of new no-dust blackboard eraser was all done very fruitful effort, also once designed many outstanding technical schemes about blackboard or slabstone.As being declared by Chen Xiancheng of the Decree of Patent Office of China on June 18th, 1998, China Patent No. (ZL) is: 98224326.X number utility model title is the utility model patent of " dust-free chalk is wiped brush ", the technical scheme that is adopted.Big group of the cleaning device of blackboard or slabstone, group's technical elements that the sucking chalk powder device is arranged is a routine of great value invention, and it has solved the problem of wiping the brush dust-free chalk effectively.But still have some deficits, it also is difficult to solve the problem that the blackboard ash descends slowly and lightly everywhere.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of new no-dust blackboard eraser.To solve the problem that the blackboard ash descends slowly and lightly everywhere.

The purpose of this utility model is achieved in that the new no-dust blackboard eraser of this utility model.Mainly constitute by suction seam, unlatching lid, hinge, micro-cleaner, battery, circuit, electric shock device, wiping skin, plate body.Its hinge, battery, micro-cleaner are by selecting for use on the market.Its suction seam is an elongate in shape, uses wood materials, through the planing operation manufacturing.Its unlatching lid is an oblong-shaped, uses wood materials, through the planing operation manufacturing.Its electric shock device is an oblong-shaped, uses metal material, through the forging and pressing processing and manufacturing.Its wiping skin is an oblong-shaped, uses felt materials, through shearing processing and manufacturing.Wipe skin and adopt method of attaching to be installed in the lower position of plate body, constitute the oblong-shaped fixed structure, function has been a scrubbing action.Hinge adopts screw method one page to be installed in the marginal position of opening lid, and one page is installed in the edge part position of plate body, constitutes movable structure, and function is to run up to move to use.Open lid and link to each other with the plate body, and cover formation box body structure on the plate body, the effect of merit storage dust by hinge.The electric shock device adopts the insertion method to be installed in the lower position of plate body, constitutes and triggers structure, and function has been an on-off action.Micro-cleaner adopts the insertion method to be installed in the interior location of plate body, constitutes fixed structure, and function has been the dust suction effect.Battery adopts the anchor clamps method to be installed in the interior location of plate body, and function has been for the source effect.So just realized the purpose of this utility model.

The advantage of utility model: big group of the cleaning device of the utility model and original blackboard or slabstone has group's technology of sucking chalk powder device to compare two advantages and improvement;

The first, because the utility model has designed dust catcher in technical scheme, so can make things convenient for dust suction;

The second, because having designed, the utility model opens lid in technical scheme, so make things convenient for dedusting, loading and unloading; Thereby just can more effectively solve the problem that the blackboard ash descends slowly and lightly everywhere.

(4) description of drawings:

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the main TV structure schematic diagram of new no-dust blackboard eraser of the present utility model;

The numbering of parts explanation in the schematic diagram: 1 inhales seam 2 unlatchings covers 3 hinges, 4 micro-cleaners, 5 batteries, 6 circuit, 7 electric shock devices, 8 wiping skins, 9 plate bodies

(5) specific embodiment:

In the optimum implementation of new no-dust blackboard eraser of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:

Its static structure: see also Fig. 1: as shown in the figure, new no-dust blackboard eraser of the present utility model.Mainly by inhale seam 1, open cover 2, hinge 3, micro-cleaner 4, battery 5, circuit 6, electric shock device 7, wiping skin 8, plate body 9 constitute.Wipe skin 8 and adopt method of attaching to be installed in the lower position of plate body 9, constitute the oblong-shaped fixed structure, function has been a scrubbing action.Hinge 3 adopts screw method one leaf to be installed in to open and covers 2 marginal position, and a leaf is installed in the edge part position of plate body 9, constitutes movable structure, and function is the action usefulness that runs up.Open and cover 2 and link to each other with plate body 9 by hinge 3, and cover on plate body 9, the formation box body structure works the dust effect of storing.Electric shock device 7 adopts the insertion method to be installed in the lower position of plate body 9, constitutes and triggers structure, and function has been an on-off action.Micro-cleaner 4 adopts the insertion method to be installed in the interior location of plate body 9, constitutes fixed structure, and function has been the dust suction effect.Battery 5 adopts the anchor clamps method to be installed in the interior location of plate body 9, and function has been for the source effect.

Its dynamic structure: in force:

Dust catcher 4 acts on dust by inhaling seam 1, and electric shock device 7 acts on blackboard micro-cleaner 4, thereby finishes the task of dust suction.Its unlatching lid 2 is opened by hinge 3, thereby finishes the task of dedusting.So just realized the purpose of this utility model.Thereby just can solve the problem that the blackboard ash descends slowly and lightly everywhere.

Below by using method, the utility model is done more detailed description:

The new no-dust blackboard eraser of this utility model is work like this:

In use, when erasing the board, the electric shock device is connected power supply, acts on dust by dust catcher 4, thereby finishes the task of dust suction.

In use, when ash was dust-full, its unlatching lid 2 passed through hinge 3, thereby finished the task of dedusting.

Realize that preferred plan of the present utility model is is material with timber, utilize the basic equipment of furniture factory, take to produce by batch greatly, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
