Abstract

The utility model relates to a health blackboard eraser, comprising a casing, an electrical system and a work device. An electric motor is used as a dynamic force to drive impeller wheels to absorb chalk dust erased by a brush into a dust absorption container. The health blackboard eraser avoids dust flying and protects the environment against pollution and a silencer arranged on the health blackboard eraser reduces noise. The utility model has the advantages of simple structure, easy fabrication and convenient operation. The utility model can be used for erasing blackboards and also removing dust from places such as families, devices, books, etc.

Description

Health eraser

Health blackboard is wiped and is belonged to the brush class that has the hold-up vessel device.It exactly is the brush class of removing the chalk writing from the blackboard supernatant.

At present, traditionally remove that chalk writing all is to use felt blackboard eraser or foam blackboard eraser on the blackboard.When this blackboard eraser erased the board, the chalk foam flew upward everywhere, and contaminated air is unhygienic, is detrimental to health, and it is time-consuming to erase the board, and efficient is low.When the blackboard eraser surface is stained with the chalk foam, to wipe untotally, the wiping quality is low, is not durable, and service life is low, in order to reduce dust, the also useful blackboard eraser that speckles with water, but this method must often clean, and could guarantee the wiping quality, uses also to bother.

The purpose of this utility model is to provide a kind of dust from flying easy to use, with low cost, no, guarantees that the Health blackboard of health is wiped.

Technical solution of the present utility model is: the utility model is made of shell (1), equipment and electrical system.Battery case (2) and spiral case (3) and form one with shell (1) on shell (1).Equipment is made of hairbrush, dust-collecting container and muffler (23), and the material of muffler (23) is nylon yarn, wire or other resistance sound material.Hairbrush is made of brush board (19) bristle (21), felt (20).Bristle (21) cluster shape is fixed on the brush board (19) equably, and felt (20) is fixed on the brush board (19) ringwise around whole bristles (21), and highly is higher than bristle (21).Air suction opening (22) is arranged on the brush board (19).Dust-collecting container is made of dust-absorbing box (17) and screen pack (18), and screen pack (18) is bonded on the dust-absorbing box (17).The power resources of equipment are in electrical system.Electrical system is made of motor (5), impeller (6), battery (13), press button (15), lead (9), conducting strip (14), spring (12) and external power supply socket (16).Motor (5) is recessed into the center of impeller (6), and is contained by impeller (6), and each blade on the impeller (6) is the hyperbola serpentine.

The utility model has the advantages that: there is not dust from flying when erasing the board, free from environmental pollution, protection user health, wiped clean, efficient height, easy to use, simple in structure, durable, easy to manufacture, specious generous.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is that the B of Fig. 1 is to view.

Embodiment of the present utility model is: impeller (6) is fitted in motor (5) and fixed mount (7) on the motor shaft, is fixed on together on the shell (1) with screw (8).Spring (12), conducting strip (14), battery (13) are contained in battery case (2) lining, install press button (15) and external power supply socket (16), connect lead (9), cover battery case lid (4), again impeller cover (10) is fixed on the shell (1) with screw (11).Dust-collecting container is inserted in the shell (1), hairbrush is contained on the shell (1) again, so just constituted the Health blackboard wiping.

During use, the hairbrush contact is moved by the cleaning piece surface, press the button switch (15), the dust that wiping is got off is because the rotation of impeller (6) forms vacuum in shell (1), and dust is by air suction opening (22), be attracted on the screen pack (18), fall in the dust-absorbing box, treat that the dust in the dust-absorbing box (17) is store when expiring, dust-collecting container can be extracted out from shell (1) and be outwelled dust.Health blackboard is wiped and also be can be used for the dedusting work that clothing, bed clothes, carpet etc. are located.
