Abstract

The utility model relates to an electric blackboard brush, which comprises a travel frame fastened on the wall surface at the top of the blackboard, an electric gear shift, and a dust collector which are installed in the travel frame, a gear and a meshed gear rack which are arranged on the electric gear shift, a brush support connected on the bottom plate of the gear shift, and felt and a brush which are embedded in the brush support. When the power switch is pressed down, the gear of the gear shift travels in the travel frame in the way of being meshed with the gear rack, the two ends of the travel frame are respectively provided with a touch type stop device, when traveling to the ends, the gear shift touches the touch type stop devices for automatic stop, and thus the wiping process is finished. Upper and lower adjusting bolts of the brush support are used for adjusting the felt and the brush to ensure the felt and the brush to be tightly pressed on the blackboard surface, and to ensure the blackboard to be cleaned. The dust collector is connected with a suction pipe, a dust collecting groove absorbs the dust generated by the felt and the brush into the dust collector, so that trouble and pollution to indoor air are eliminated, and the electric blackboard brush is thus favorable for the physical and mental health of working and studying people.

Description

The driven blackboard brush

Technical field

The utility model relates to a kind of blackboard brush, particularly a kind of electric dustless eraser.

Background technology

The present blackboard brush that uses is the artificial hand wiper and smears, and no electronic and dust arrester is after writing on the blackboard, describing, promptly by hand with the blackboard wiped clean, dust from flying causes indoor environment and air pollution, is harmful to office work, study personnel's physical and mental health.

Content when sending out

Invention of the present utility model is for eliminating the worry that the manual wipping blackboard brings, eliminating indoor environment and air pollution that dust causes.Physically and mentally healthy and a kind of electric dustless eraser that provides of work, study personnel is provided.

In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is: the driven blackboard brush, its feature comprises: be fastened on the stroke walking frame (1) on the wall of blackboard top and be installed in (1) interior electric gear shift(ing) (2), dust catcher (14), scroll wheel (5) supports electric gear shift(ing) (2), gear (3), tooth bar (4), switch (7) joining power, felt, hairbrush (9) is inlaid on the brush holder (8), a touching crane device (6) is respectively installed at walking frame (1) two ends, dust catcher (14) connects sweep-up pipe (15), bothrium (16) is adjusted bolt (11), (13) regulation and control felt, the degree of tightness of hairbrush (9).Return pulley seat (12) is welded on brush holder (8) bottom, and return pulley (10) is installed on the return pulley seat (12), and return pulley (10) withstands lower edge plate (17), can adjust brush holder (8) bottom degree of tightness, and portable plate (18) can be opened to remove and store dust in the dust catcher.When brush moved, dust catcher absorbed the dust under felt, the hairbrush brush, reached the purpose of dedusting.The walking frame two ends are respectively installed one and are touched lugs, and brush moves to the blackboard end, the contact lugs, and transmission system, dust catcher shuts down.

During use, press power switch, transmission system, dust catcher starts simultaneously, transmission system is by gear, and felt, the hairbrush that rack drives is pressed blackboard panel wipes out the writing on the blackboard, and dust catcher is with in the suction of the dust the wiping under dust catcher, transmission system touches lugs, wiping dust suction process stops, and presses the backward going power switch, the transmission system backward going, touch other end lugs, oppositely wiping, dust suction process stop.

The utility model novelty simple in structure has originality, and easy-to-operate can be removed the worried and inconvenient of manual wipping blackboard, save time, laborsaving, clean hygiene, can stop dust from flying, prevent to pollute indoor environment and air, compliance with environmental protection requirements helps work, study personnel physical and mental health.
