Abstract
A self-power-generating dust absorption blackboard eraser comprises a blackboard eraser body and a handle, the bottom surface of the blackboard eraser body is provided with a plurality of through holes, a circle of retaining member is arranged on the periphery of the bottom surface of the blackboard eraser body, a dust collector is arranged in the blackboard eraser body, the upper surface of the blackboard eraser body is provided with the handle, and the surface of the handle is provided with a self-power-generating pressing device which is connected with a storage battery located in the blackboard eraser body through a wire. When the self-power-generating dust absorption blackboard eraser is used, generated electric energy can be stored in the storage battery by means of pressing of the self-power-generating pressing device at the position of the handle, electricity is supplied to the dust collector in the blackboard eraser body, an additional power supply does not need to be arranged, and energy sources are saved. The retaining member on the periphery of the bottom surface of the blackboard eraser body can prevent dust from flying outwards when the blackboard eraser is used for cleaning the surface of a blackboard by teachers and students. The self-power-generating dust absorption blackboard eraser has the advantages that the self-power-generating dust absorption blackboard eraser is simple and reasonable in structure, the self-power-generating operating principle is applied to the dust absorption blackboard eraser, the energy resources are saved, and the requirements for low carbon and environment protection in modern society are met.
Description
Technical field the utility model relates to a kind of realia, especially a kind of self power generation dust absorption blackboard eraser.
Background technology is well-known, blackboard eraser is one of upper requisite articles for use of class hour blackboard wiping writing on the blackboard of teachers and students, but existing dust absorption blackboard eraser has inconvenience in use, for example: existing dust absorption blackboard eraser does not have the function that self power generation provides electric energy, can not satisfy teachers and students' use needs.
Summary of the invention the utility model provides a kind of self power generation dust absorption blackboard eraser for the deficiencies in the prior art, does not have the problem of spontaneous electrical function to solve existing dust absorption blackboard eraser.
The utility model comprises blackboard eraser main body and handle, is provided with a plurality of open-works in the bottom surface of blackboard eraser main body, and is provided with a corral gear at the periphery place of blackboard eraser main body bottom surface; Inside in the blackboard eraser main body is provided with dust catcher; Upper surface in the blackboard eraser main body is provided with handle, and is provided with the self power generation press device on the surface of handle, and the self power generation press device is connected with the battery that is positioned at the blackboard eraser body interior by wire; The motor of dust catcher is connected with battery, switch.
After adopting said structure, during use, by the self power generation press device at squeeze grip place, the electric energy that produces can be stored in battery, for the dust catcher of blackboard eraser body interior provides power supply, and need not another stand-by power source, save the energy; The enclosing at blackboard eraser main body bottom periphery place can when teachers and students use blackboard eraser blackboard wiping plate face, avoid dust to raise outward.
The beneficial effects of the utility model are: simple in structure, structure rationally is applied to the operation principle of self power generation in dust absorption blackboard eraser, saves the energy, meets the demand of society low-carbon environment-friendly.
Appended drawings 1 is front view of the present utility model.
The specific embodiment in the front view of self power generation dust absorption blackboard eraser, comprises blackboard eraser main body 1 and handle 2 as shown in the figure, is provided with a plurality of open-works 3 in the bottom surface of blackboard eraser main body, and is provided with a corral gear 4 at the periphery place of blackboard eraser main body bottom surface; Be provided with dust catcher 5 in the inside of blackboard eraser main body; Upper surface in the blackboard eraser main body is provided with handle, and is provided with self power generation press device 6 on the surface of handle, and the self power generation press device is connected with the battery that is positioned at the blackboard eraser body interior by wire; The motor of dust catcher is connected with battery, switch.During use, only need to press the self power generation press device, the dust catcher that namely can be the blackboard eraser body interior provides electric energy.
