Description
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, and big group of the cleaning device of blackboard or slabstone has the little technical group field of sucking chalk powder device.Classification number is B43L21/02.
At present, the technology about the sucking chalk powder device is arranged existing and that once had was all done very fruitful effort to the demand of novel blackboard eraser, also once designed many outstanding technical schemes.As being declared by Wang Hongjun of the Decree of Patent Office of China in 1996, Granted publication number is CN2239896Y, and China Patent No. (ZL) is: 95245467.X number utility model title is the utility model patent of " dust-sucking eraser ", the technical scheme that is adopted.Having aspect the sucking chalk powder device technique is a routine of great value invention, and it has solved the problem of blackboard eraser dust suction effectively.But still have some deficits, it is how grey that it also is difficult to solve old-fashioned blackboard eraser, the problem of inconvenience when water to wipe.
The purpose of this utility model is to provide a kind of novel blackboard eraser.How grey to solve old-fashioned blackboard eraser, the problem of inconvenience when water to wipe.
The purpose of this utility model is achieved in that a kind of novel blackboard eraser of this utility model.Mainly constitute by water tank, valve, spring, rubber cushion, water inlet, mistake water layer, sponge, tight loop, apopore.Its spring, sponge, tight loop are by selecting for use on the market.Its water tank, mistake water layer are rectangular shapes, use plastic material, through the injection moulding processing and manufacturing.Its valve is " worker " word shape, uses plastic material, through the injection moulding processing and manufacturing.Its rubber cushion is a plate shape, uses elastomeric material, through synthetic processing and manufacturing.Its inlet opening is a hole shape, through changeing the hole processing and manufacturing.Valve adopts method of press-fitting to be installed in an end position of water tank, constitutes conjuncted structure, and function has been an on-off action.Spring adopts the method for being inserted in to be installed in the center pillar position of valve, constitutes the coil shape embedded structure, and function has been tight lock effect.Rubber cushion adopts adhering method to be installed in the lower end position of valve, constitutes the conjuncted structure of T-shaped shape, and function is to seal.Water inlet adopts changes the lower position that the hole method is manufactured on water tank, constitutes hole shape, and function has been the water inlet effect.Cross water layer and adopt adhering method to be installed in the lower position of water tank, constitute conjuncted structure, function had been the water effect.Function had been the water effect.Sponge adopts adhering method to be installed in the lower position of water layer, constitutes conjuncted shape wipe configuration, and function has been the effect of wiping.Tight loop employing adhering method is installed in the location about of sponge, the conjuncted structure of looping shape, and function has been a fixation.Apopore adopts changes the basal surface position that the hole method was manufactured on water layer, constitutes hole shape, and function has been the water outlet effect.So just realized the purpose of this utility model.
The advantage of utility model: the utility model has been compared two advantages and improvement with the original sucking chalk powder device technique that has;
The first, because the utility model designed water tank in technical scheme, so can water storage;
The second, because the utility model has designed valve in technical scheme, so can control water outlet automatically; Thereby how grey just can more effectively solve old-fashioned blackboard eraser, the problem of inconvenience when water to wipe.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the main TV structure schematic diagram of a kind of novel blackboard eraser of the utility model;
Fig. 2 is the water layer structural representation excessively of a kind of novel blackboard eraser of the utility model;
The numbering of parts explanation in the schematic diagram: 1 water tank, 2 valves, 3 springs, 4 rubber cushions, 5 water inlets 6 are crossed water layer 7 sponges 8 tight loops 9 apopores
In the optimum implementation of a kind of novel blackboard eraser of the 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: as shown in the figure, a kind of novel blackboard eraser of the utility model.Mainly constitute by water tank 1, valve 2, spring 3, rubber cushion 4, water inlet 5, mistake water layer 6, sponge 7, tight loop 8, apopore 9.Valve 2 adopts method of press-fitting to be installed in an end position of water tank 1, constitutes conjuncted structure, and function has been an on-off action.Spring 3 adopts the method for being inserted in to be installed in the center pillar position of valve 2, constitutes the coil shape embedded structure, and function has been tight lock effect.Rubber cushion 4 adopts adhering method to be installed in the lower end position of valve 2, constitutes the conjuncted structure of T-shaped shape, and function is to seal.Water inlet 5 adopts changes the lower position that the hole method is manufactured on water tank 1, constitutes hole shape, and function has been the water inlet effect.Cross water layer 6 and adopt adhering method to be installed in the lower position of water tank 1, constitute conjuncted structure, function had been the water effect.Sponge 7 adopts adhering method to be installed in the lower position of layer 6, constitutes conjuncted shape, and function had been the water effect.Sponge 7 adopts adhering method to be installed in the lower position of water layer 6, constitutes conjuncted shape wipe configuration, and function has been the effect of wiping.Tight loop 8 employing adhering methods are installed in the location about of sponge 7, the conjuncted structure of looping shape, and function has been a fixation.Apopore 9 adopts changes the basal surface position that the hole method was manufactured on water layer 6, constitutes hole shape, and function has been the water outlet effect.
Its dynamic structure: in force:
According to the path principle, its water acts on sponge 7 by apopore 9, thereby finishes erasing the board of task.So just realized the purpose of this utility model.Thereby how grey just can solve old-fashioned blackboard eraser, the problem of inconvenience when water to wipe.
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, in the time of in the time will using the wet rubbing blackboard, open valve, according to the path principle, its water acts on sponge 7 by apopore 9, thereby finishes erasing the board of task.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of small plastic processing factory, take to produce by batch in small batches, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
