Description

A dustproof blackboard eraser

technical field

The utility model relates to the technical field of teaching appliances, in particular to a dust-proof blackboard eraser.

Background technique

Chalk is a tool widely used in daily life and is generally used for writing on blackboards. Because of its low price and easy use, it is widely used in teaching.

But in the process of cleaning the blackboard with a blackboard eraser, the dust will continue to fall and spread around the blackboard. Dust particles have a strong ability to adsorb bacteria and are alkaline components. After being inhaled by the human body, they will cause varying degrees of harm to the human respiratory system, ears, nose, throat and other parts, seriously endangering the health of teachers and students. .

In addition, the existing blackboard erasers usually have insufficient ability to clean the blackboard, so that the cleaned blackboard usually retains the last writing marks. When writing again, the rewritten content is mixed with the last writing marks, which affects writing. The legibility of the content.

detailed description

In order to enable those skilled in the art to better understand the technical solution in the utility model, the technical solution in the utility model embodiment will be clearly and completely described below in conjunction with the accompanying drawings in the utility model embodiment. Obviously, The described embodiments are only some of the embodiments of the present utility model, but not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

Fig. 1 is a schematic structural diagram of a dust-proof blackboard eraser provided by the embodiment of the utility model. area and dry erase area. In order to achieve a better cleaning effect, the blackboard should be cleaned with the vacuum area as the front and the dry wipe area as the rear, so that the same area of the blackboard can be cleaned three times with the brush 102, wet rag and dry rag, to achieve better Good cleaning effect. In addition, since there are dust suction holes 103 between the bristles 102, the dust is collected into the dust collection chamber 104 under the negative pressure of the dust suction holes 103, so as to prevent the dust from flying around and polluting the environment. Each part will be described in detail below in conjunction with the accompanying drawings.

In the embodiment of the utility model, the dust suction area includes a bristle board 101, on which bristle board 101 is provided with bristles 102 and dust suction holes 103, and the top of the bristle board 101 is provided with a dust collection chamber 104 and a dust suction unit in sequence 105 , the dust suction hole 103 is connected to the dust collection chamber 104 through a dust suction pipe 107 , and an airflow passage is formed between the dust suction unit 105 , the dust suction chamber, the dust suction pipe 107 and the dust suction hole 103 . The dust suction unit 105 can provide suction to form a negative pressure at the dust suction hole 103 , and when there is dust at the dust suction hole 103 , the dust can be sucked into the dust collection chamber 104 along the airflow under the action of the negative pressure. In order to collect the dust in the dust collection chamber 104, a filter screen 106 is provided between the dust suction unit 105 and the dust collection chamber 104, and the filter screen 106 has a filter hole smaller than the dust of chalk.

Due to the limited cleaning ability of the bristles 102, writing marks may still exist on the surface of the blackboard cleaned by the bristles 102. In order to thoroughly clean the blackboard, the utility model embodiment is also provided with a wet wiping area behind the dust suction area, and the wet wiping area includes a first wiping unit 108 arranged at the bottom of the housing, and the first wiping unit 108 can be Rag or sponge, the utility model embodiment is described with rag as an example. Since the top of the first wiping unit 108 is provided with a water tank 109, a water seepage plate 110 is provided between the water tank 109 and the first wiper unit 108, the water or cleaning fluid in the water tank 109 can seep into the rag through the water seepage hole 111 on the water seepage plate 110 on, so that the wipe becomes a damp wipe. Since the wet rag has a better cleaning effect, it can completely remove the remaining writing marks on the blackboard.

After cleaning with a damp cloth, water stains may remain on the blackboard, which will affect the next writing. Based on this, the embodiment of the utility model also has a dry wiping area behind the wet wiping area. The dry wiping area includes a second wiping unit 112 arranged at the bottom of the housing. The first wiping unit 108 can be a rag or a sponge. The novel embodiment will be described with a rag as an example. Since the rags in the dry-erase area are dry rags, water stains on the gangsters can be easily wiped off to achieve a thorough cleaning of the blackboard.

Optionally, the dust collection chamber 104 is detachably connected to the casing, and when the dust collection chamber 104 is full of dust, the dust collection chamber 104 can be removed from the casing to facilitate dust dumping.

Optionally, there are multiple dust suction holes 103, and the bristles 102 and the dust suction holes 103 are arranged at intervals, which can achieve better dust suction effect.

Optionally, the end of the dust suction pipe 107 connected to the dust collection chamber 104 is located at the upper part of the dust collection chamber 104, which can prevent excessive dust from blocking the dust suction pipe 107.

Optionally, the dust collection unit 105 is a fan or a vacuum pump, and of course it can also be other devices, which are not specifically limited in the present invention.

Optionally, a water injection hole 113 is provided on the top of the water tank 109 to add water or cleaning fluid to the water tank 109 .

Optionally, there are multiple water seepage holes 111, and the multiple water seepage holes 111 are evenly arranged on the water seepage plate 110, so that the wet rag can be evenly humidified and the cleaning effect can be improved.

Optionally, the second wiping unit 112 is spaced apart from the first wiping unit 108 to prevent water from the first wiping unit 108 from penetrating into the second wiping unit 112 .

It can be seen from the above technical solution that the dust-proof blackboard eraser provided by the embodiment of the utility model can collect the dust from the bristles into the dust collection chamber under the suction of the dust suction unit, so as to avoid the dust from floating around and polluting the surroundings. environment, and then use the first wiping unit and the second wiping unit to further clean the area brushed by the bristles, so as to avoid residual writing marks on the blackboard.
