Abstract
The utility model relates to an automatic powder-absorbing blackboard eraser, which comprises a shell, a micro-motor, a motor-mounting base, a fan, a brush, high-density filter screens, an air suction cup cavity, a motor room, a filter screen cover, a storage battery, a holddown spring, a storage battery cover, a charging jack, a control switch and an outer netty fan cover; wherein, the brush, the high-density filter screens and the air suction cup cavity are arranged on the left side of the shell of the blackboard eraser; the micro-motor and the motor room are arranged in the right upper part of the shell; the storage battery is arranged in the lower part; and the control switch is arranged on the outside of the shell. The electrical parts are integrated with the air suction cup cavity, the high-density filter screens and the brush. When the blackboard eraser is used, after the control switch is switched on, the micro-motor rotates along with the fan in order to exhaust the air in the air suction cup cavity, so that negative pressure can be generated, thereby, the powder on the blackboard eraser can flow to the high-density filter screens under the force of the air and is filtered to deposit, and the redundant air can be exhausted from the motor room through the air suction cup cavity. When the blackboard eraser is not used, the filter screen cover is opened, and the filter screens are taken out and washed by water and can be used for the second time after being aired. Since the blackboard eraser is provided with the storage battery cover, the storage battery can be conveniently taken out of and put into the blackboard eraser, and the blackboard eraser is characterized by reasonable design, simple operation, environment-friendliness, convenient use, and the like.
Description
Technical field
The utility model relates to a kind of blackboard eraser, and particularly a kind of automatic dust-absorption eraser belongs to the realia field.
Background technology
For a long time, the people's teacher are in the educational undertaking hard work that is motherland, when making huge contribution, he (she) also bearing a kind of misery dumbly: that be exactly dust give he (she) the infringement that brings.The utility model is from the angle of environmental protection, and the blackboard eraser that can absorb dust automatically is provided, and to alleviating environmental pollution, the protection teachers ' health will play good effect, receives gratifying effect.
Summary of the invention
The purpose of this utility model is exactly the automatic dust-absorption eraser a kind of reasonable in design, simple to operate, easy to use that provides for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of automatic dust-absorption eraser, comprise: between housing, micromachine, motor mount, fan, hairbrush, high density filter screen, air sucker chamber, motor, filter cover, battery, holddown spring, battery cap, charging socket, gauge tap, the netted outer cover of fan, it is characterized in that:
The arranged outside of described housing has hairbrush, is disposed with 2-3 floor height density filter screens to the right, and air sucker chamber is set then, and with the motor on right side between communicate, be convenient to air and get rid of.Micromachine is set between motor, and is fixed on the motor mount with bolt, motor one end is installed fan and the netted outer cover of fan.The bottom is provided with battery, charging socket, holddown spring and battery cap, and hull outside is provided with gauge tap.Micromachine, battery, gauge tap three link to each other by the positive and negative the two poles of the earth of lead and its.By the blackboard eraser housing micromachine, battery and hairbrush, high density filter screen, air sucker chamber are interconnected, constitute an integral body.During use, open gauge tap, micromachine starts together with fan, takes air in the air sucker chamber away, form negative pressure, the blackboard eraser dust flows to the high density filter screen under the effect of air, and remains, and the air after its process is filtered is through getting rid of outside the blackboard eraser between motor.When stopping using, open the filter screen flap, take out filter screen, water cleans, and dries the back so that use for the second time, the utlity model has characteristics such as reasonable in design, simple to operate, environmental, easy to use.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.Wherein: the 1st, housing, the 2nd, micromachine, the 3rd, motor mount, the 4th, fan, the 5th, hairbrush, the 6th, high density filter screen, the 7th, air sucker chamber, the 8th, between motor, the 9th, filter cover, the 10th, battery, the 11st, holddown spring, the 12nd, battery cap, the 13rd, charging socket, the 14th, gauge tap, the 15th, the netted outer cover of fan.
The specific embodiment
See also shown in Figure 1ly, be the utility model specific embodiment, wherein, described housing 1 left side is provided with hairbrush 5 and 2-3 floor height density filter screens 6, and air sucker chamber 7 is set then again, and with the motor on housing 1 right side between 8 communicate.Between motor, with bolt micromachine 2 is fixed on the motor mount 3 in 8, and on motor shaft, fan 4 is installed, add 1 netted outer cover 15 of fan.
Described micromachine 2 belows are provided with battery 10, charging socket 13, shell is provided with gauge tap 14, and make micromachine 2, battery 10, gauge tap 14 connect positive and negative the two poles of the earth by lead, hairbrush 5, high density filter screen 6, air sucker chamber 7 are assembled in the housing 1 together with micromachine 2, battery 10, constitute an integral body.
What deserves to be explained is that for guaranteeing to obtain the effect of automatic dust absorption, the size of micromachine rated power is please called the device professional person and selected, this paper no longer states.
