Abstract

The utility model discloses a pollutionless and dustless cleaner. The plane periphery of a base plate of the cleaner is stuck with ring edges of rubber materials, and the plate body is stuck with multiple wool strips. A gap is arranged between the wool strip and is used as a dust suction cavity, and the plane of rubber ring and the plane of wool strip are in the same horizontal line. The utility model solves the problem of dust nuisance of chalks, protects environment sanitation in classrooms, and reduces the bad influence of chalk dust to the health of teachers and students.

Description

The environment-friendly dustless cleaner

The utility model relates to a kind of teaching aid, is a kind of environment-friendly dustless cleaner of removing the blackboard chalk writing concretely.

Generally use ordinary blackboard eraser to remove chalk writing on the blackboard at present, the primary structure of this blackboard eraser is the wool top of even bonding one deck densification on the blackboard eraser base plate, when removing on the blackboard chalk writing with the blackboard eraser of this structure, often chalk dust flies upward everywhere, not only influence the classroom environment health, and have a strong impact on the healthy of teachers and students.

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of environment-friendly dustless cleaner that chalk dust flies upward that do not have when removing on the blackboard chalk writing is provided.

The purpose of this utility model realizes by following technical proposals:

Plane periphery bonded adhesives leather material circle limit on base plate, and on plate body bonding several wool tops, be provided with the gap between wool top and make vacuum chamber, on the rubber circle on plane and the wool top plane on same horizontal line.

For increasing environment-friendly dustless cleaner service life, on base plate, be provided with groove, groove shapes is consistent with the wool top shape, so that chimeric bonding with wool top.

The also available foamed plastics of said wool top is made substitute.

The utility model mainly utilizes the environment-friendly dustless cleaner to be provided with vacuum chamber; vacuum chamber very easily produces negative pressure when cleaner and blackboard connect friction and wipe; chalk dust under the wiping is stored in the vacuum chamber; slowly tremble again in other container after the wiping; solve chalk dust preferably and flown upward problem; both protected environmental sanitation in the classroom, significantly reduced the influence healthy of chalk dust again teachers and students.

From above-mentioned situation as can be known the purpose of this utility model can realize.

Fig. 1 is the utility model configuration diagram;

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings below.

As shown in Figure 1, the utility model comprises base plate 1, a periphery bonding rubber circle limit 2 in plane on the base plate 1, and on plate body bonding several wool tops 3, be provided with the gap between wool top and make vacuum chamber 4, the distribution shape of wool top designs as required, the present embodiment design has two rectangle wool tops of two waveform wool tops and both ends to constitute, the height of the high ejecting plate face of wool top is good with 1-2cm, originally is embodied as 1.5cm, considers the service life that increases the environment-friendly dustless cleaner, present embodiment is provided with two waveform grooves on base plate and both ends are provided with two rectangular recess, so that chimeric bonding with waveform and rectangle wool top, the degree of depth of groove designs as required, and present embodiment is selected 0.3cm for use.Said wool top can be made substitute with foamed plastics, and the last plane of rubber circle and the last plane of wool top are on same horizontal plane.
