Abstract
The utility model relates to a rechargeable dust absorbing eraser. An airflow passage is arranged under a brush and connected with a turbine type induced draft fan, an air guide passage is arranged on one side of the turbine type induced draft fan and connected with a detachable dust collecting bag via a bayonet, a row of vent holes is arranged on a cover close to the bottom of the dust collecting bag, eraser cover bayonets are arranged at two ends of the airflow passage, and the airflow passage can be curved. The dust absorbing eraser is high in efficiency, reduces dust pollution greatly, and has fine dust absorbing effect due to action of the turbine type induced draft fan, so that most of dust can be absorbed into the dust collecting gag. Simultaneously, the eraser is low in motor power, energy consumption and manufacturing cost, fine in safety and long in service life and is rechargeable and reusable. As the size of the eraser is similar to that of a general eraser, the rechargeable dust absorbing eraser is easy and light and is convenient in use.
Description
Technical field
The utility model relates to teaching aid, is specifically related to a kind of rechargeable dust-sucking eraser, belongs to International Classification of Patents B43L21/02 technical field.
Background technology
Traditional blackboard eraser, cleaning efficiency is low, can stay dust after the wiping on the blackboard surface, and dust very easily falls, and is mingled in the air, makes those presents constantly eat into chalk dust, endangered healthy.And still do not have at present a kind of blackboard eraser that can solve dust problem with general applicability.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of dust absorption blackboard eraser of rechargeable type is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of rechargeable dust-sucking eraser, comprise scrubbing brush, motor, the battery case of motor one side, the parts such as outlet in the battery case outside are formed, there is gas channel the scrubbing brush below, and gas channel links to each other with the turbine type air exhauster, and a side of turbine type air exhauster has fixing air guide channel, air guide channel joins by bayonet socket and dismountable dirt bag that connects, and near connecing dirt bag bottom one row's passage is being arranged.There is blackboard eraser lid bayonet socket at the gas channel two ends.Gas channel can be arcwall face.
Rechargeable dust-sucking eraser of the present utility model, the service efficiency height greatly reduces contamination by dust.Because turbine air exhauster role makes pick-up performance good, most of dust is inhaled into and connects in the dirt bag.Simultaneously, power of motor is little, and is chargeable, and it is little to consume energy, and cost of manufacture is low, and security performance is good, and is reusable, and the life-span is long.Its size is also close with common blackboard eraser, and is lightly easy-to-use, easy to use.
Description of drawings
Accompanying drawing is a sectional structure schematic diagram of the present utility model.
Among the figure: 1, scrubbing brush, 2, gas channel, 3, the turbine type air exhauster, 4, air guide channel, 5, connect the dirt bag, 6, passage, 7, motor, 8, blackboard eraser lid bayonet socket, 9, battery case, 10, outlet.
The specific embodiment
Referring to accompanying drawing, rechargeable dust-sucking eraser has the gas channel 2 of arcwall face for 1 time at scrubbing brush, and this passage links to each other with turbine type air exhauster 3 again.One side of turbine type air exhauster 3 has fixing air guide channel 4.Air guide channel 4 by bayonet socket with detachably connect dirt bag 5 and join.Near connecing covering of dirt bag 5 bottoms, row's passage 6 is arranged.The opposite side of low-power machine 7 is a battery case 9, and there is outlet 10 in the outside of battery case 9.
Before the use, the rechargeable battery of packing in battery case 9/common AA battery perhaps links to each other the external power supply electric wire with outlet 10.
During use, open the gauge tap that links to each other with battery case 9, motor 7 runnings this moment drive 3 runnings of turbine type air exhauster.When the user erased the board, scrubbing brush 1 can make the dust on the blackboard break away from blackboard.This moment, the air pressure of gas channel 2 was lower than air pressure around the scrubbing brush 1 because the effect of turbine air exhauster 3, so air can drive dust and enter gas channel 2, and entered air guide channel 4 under the effect of air exhauster 3, finally entered and connect dirt bag 5.Dust can be stayed and connect in the dirt bag 5, and the air that is inhaled into can be discharged blackboard eraser by row's passage 6.
Can regularly open blackboard eraser lid bayonet socket 8, check the dust accumulation that connects in the dirt bag 5.Dust will connect the dirt bag more for a long time and take off, and sack be loaded onto after the dust cleaning again, continue to use.
If what use is rechargeable battery, when not using blackboard eraser, can charge by the rechargeable battery in 10 pairs of battery cases of outlet 9 with external power supply.
