Description

A kind of novel blackboard eraser

(1) technical field:

The utility model relates to a kind of novel 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, 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 novel blackboard eraser was all done very fruitful effort, also once designed many outstanding technical schemes about blackboard or slabstone.As being declared by Huang Dahong of the Decree of Patent Office of China in 1996, Granted publication number is CN2219215Y, and China Patent No. (ZL) is: No. 95205760.3 utility model title is the utility model patent of " Blackboard cleaner ", the technical scheme that is adopted.Big group of the cleaning device of blackboard or slabstone, it is a routine of great value invention that group's technical elements of inhaling the chalk device is arranged, and it has solved the problem of Blackboard cleaner effectively.But still have some deficits, it also is difficult to solve and erases the board is that dust is to the disadvantageous problem of people entirely.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of novel blackboard eraser.Erasing the board with solution is that dust is to the disadvantageous problem of people entirely.

The purpose of this utility model is achieved in that a kind of novel blackboard eraser of this utility model.Mainly by plank, screw, handle, dust box, put dirt mouth, switch, motor, bristle, battery cover, dust-absorbing flue, suction hole and constitute.Its screw, handle, motor, bristle are by selecting for use on the market.Its plank is an oblong-shaped, uses wood material, through the planing operation manufacturing.Its dust box, switch, put the dirt mouth, battery cover is an oblong-shaped, uses plastic material, through the injection moulding processing and manufacturing.Bristle adopts adhering method to be installed in the lower position of dust box, constitutes the oblong-shaped fixed structure, and function has been the effect of erasing the board.The dust box adopts adhering method to be installed in the lower position of plank, constitutes the oblong-shaped fixed structure, and function has been a mass action.Battery cover adopts the close-coupled method to be installed in the lateral location of dust box, constitutes the oblong-shaped enclosed construction, and function has been the power supply effect.Put the dirt mouth and adopt the close-coupled method to be installed in the lateral location of dust box, constitute the oblong-shaped enclosed construction, function has been to put the dust effect.Motor adopts adhering method to be installed in the medium position of dust box, constitutes fixed structure, and function has been the dust suction effect.Handle adopts the screw fixing means to be installed in the upper position of plank, constitutes fixed structure, and function has been the convenient effect of using.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 three advantages and improvement;

The first, because the utility model has designed handle in technical scheme, so be easy to use;

The second, because the utility model has designed motor in technical scheme, so but dust suction;

The 3rd, because the utility model has designed the dust box in technical scheme, so can hold dust; Thereby just more effectively having solved erases the board is that dust is to the disadvantageous problem of people entirely.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the last TV structure schematic diagram of a kind of novel blackboard eraser of the present utility model;

Fig. 2 is that the master of a kind of novel blackboard eraser of the present utility model cuts open structural representation;

Fig. 3 is the following TV structure schematic diagram of a kind of novel blackboard eraser of the present utility model;

The numbering of parts explanation in the schematic diagram: 1 plank, 2 screws, 3 handles, 4 dust boxes 5 are put dirt mouth 6 switches 7 motors 8 bristles 9 battery covers 10 dust-absorbing flues 11 and are inhaled the hole

(5) specific embodiment:

In the optimum implementation of a kind of novel 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, a kind of novel blackboard eraser of the present utility model.Mainly by plank 1, screw 2, handle 3, dust box 4, put dirt mouth 5, switch 6, motor 7, bristle 8, battery cover 9, dust-absorbing flue 10, inhale hole 11 and constitute.Bristle 8 adopts adhering method to be installed in the lower position of dust box 4, constitutes the oblong-shaped fixed structure, and function has been the effect of erasing the board.Dust box 4 adopts adhering method to be installed in the lower position of plank 1, constitutes the oblong-shaped fixed structure, and function has been a mass action.Battery cover 9 adopts the close-coupled method to be installed in the lateral location of dust box 4, constitutes the oblong-shaped enclosed construction, and function has been the power supply effect.Put dirt mouth 5 and adopt the close-coupled method to be installed in the lateral location of dust box 4, constitute the oblong-shaped enclosed construction, function has been to put the dust effect.Motor 7 adopts adhering method to be installed in the medium position of dust box 4, constitutes fixed structure, and function has been the dust suction effect.Handle 3 adopts the screw fixing means to be installed in the upper position of plank 1, constitutes fixed structure, and function has been the convenient effect of using.

Its dynamic structure: in force:

Its dust box 4 acts on dust by motor 7, thereby finishes the task of dust suction.Its plank 1 acts on hand by handle 3, thereby finishes the task of making things convenient for taking and placing.So just realized the purpose of this utility model.Thereby just having solved erases the board is that dust is to the disadvantageous problem of people entirely.

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

A kind of novel blackboard eraser of this utility model is work like this:

In use, when erasing the board, its dust box 4 acts on dust by motor 7, thereby finishes the task of dust suction.Its plank 1 acts on hand by handle 3, thereby finishes the task of making things convenient for taking and placing.
