Abstract

The utility model relates to a dust suction coating brush. The utility model is composed of a housing, a soft brush, a hard brush, a motor, a dust box, etc., wherein, the front end of the housing is provided with a power supply box, the center part of the housing is provided with the motor, and the back end of the housing is provided with the dust box; the bottom of the housing is connected with a fixing plate, and the soft brush and the hard brush are arranged on the fixing plate; the center part of the fixing plate is provided with a circular hollow cavity. On one hand, the utility model can be used for sufficiently and cleanly wiping letters written by chalks through the actions of the soft brush and the hard brushes, and the other hand, the utility model can suck wiped dust in a dust suction box through the action of the suction force of a fan on the motor. Therefore, the utility model which solves the defect that the dust is caused during the course that the letters written by chalks are wiped improves a teaching environment in a classroom and effectively ensures physical and mental health for people.

Description

Dust-absorption brush

The utility model relates to the culture and education apparatus.

Current, widely used whitewashing in school all lacks dust suction, when whitewashing the letter written with chalk of wiping on the blackboard, often causes dust to rise from all around, and very easily is inhaled into, and often gives rise to diseases harm people's physical and mental health aspect respiratory system.

The purpose of design of dust-absorption brush of the present utility model is by hard brush, soft brush effect, can fully wipe letter written with chalk on the blackboard, simultaneously, has automatic dust-collection function, the dust of wiping is absorbed into dust box by the fan effect, thereby solved the shortcoming that original dust rises from all around, like this, can improve teaching environment greatly.

The art designs scheme of dust-absorption brush of the present utility model is: be made up of institutes such as housing, fixed head, hard brush, soft brush, motor, fan, dust board and dust suction sponges.The front end of housing has power supply box, and there is motor the centre, and the rear end is a dust box, and sealing gasket and fixing the three with fixed screw is arranged with between fixed head.

Dust-absorption brush of the present utility model is provided with soft brush around fixed head, the inboard is provided with hard brush, at central authorities' replacement garden shape cavity of fixed head and sealing gasket.

Dust-absorption brush of the present utility model, motor are installed in housing central authorities, and fan just in time is embedded in the shape cavity of garden, and the pressing switch starts fan dust is sucked dust box.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated

Fig. 1 is the cut-away view of dust-absorption brush of the present utility model

Fig. 2 is the diagrammatic sketch of facing upward of dust-absorption brush of the present utility model

Fig. 3 is the stereogram of dust-absorption brush of the present utility model

With reference to Fig. 1～Fig. 3, dust-absorption brush of the present utility model, by housing 1, fixed head 8, soft brush 3, brush 4 firmly, institute such as motor 5, fan 6, dust board 7, dust suction sponge 12 forms.8 of housing 1 and fixed heads have a sealing gasket 11, and by fixed screw 9 three are fixed, and soft brush 3 is housed on the fixed head 8, brushes 4 firmly, get into cavity in the middle of the fixed head 8, and soft brush 3 is distributed in the periphery, brush 4 firmly and enclose in being distributed in.Motor 5 is fixed on the housing 1, housing 1 two ends are provided with power supply box 2 and dust box 10, at dust box 10 air inlets a movable dust board 7 is arranged, the top of dust board 7 is stuck on the housing 1, in use, and by the thrust of vertical effect of center of gravity and wind, dust board 7 is opened automatically, when being placed on the desk, dust board 7 is shut automatically because of the gravity effect, makes dust box 10 interior dust can not refund motor 5 places.Air outlet at dust box 10 is provided with dust suction sponge 12, makes dust wind obtain filtering.Therefore, when dust-absorption brush uses, according to holding posture, switch 13 starter motors 5 under the thumb pressing rotate fan 6 and absorb because of soft brush 3 and the dust under brush 4 is wiped firmly, send into dust box 10, and, like this, can effectively control phenomenons such as dust rises from all around through 12 filtrations of dust suction sponge, improve near the teaching environment in dais, classroom, thereby ensure people's physical and mental health.
