Abstract

The utility model discloses a sanitary blackboard device, which comprises a blackboard surface, wherein tracks are arranged at the upper end and the lower end of the blackboard surface, and a vertical long hair brush is arranged on the blackboard surface; the two ends of the long hair brush are provided with pulleys, and a blackboard groove and cleaners are arranged on the track at the lower end; the cleaners are arranged in the blackboard groove, and the blackboard groove is in a long-groove shape and is deep; and each cleaner comprises a motor and fan blades. The utility model has the advantages of convenient and flexible use, cleanness and sanitary, simple installation and no harm to the health of users; since a lower end cover of the blackboard groove can be flexibly opened, chalk dust does not fly everywhere, the cleaning is more convenient, and the time and labor are saved.

Description

A kind of health blackboard device

Technical field

The present invention relates to a kind of teaching equipment, more particularly, it relates to a kind of health blackboard.

Background technology

Now China pays much attention to education, and what often use in the conventional teaching is black board teaching, and teacher is for the student can be succeeded in school, understand clear, detailed explanation and go out a lot of topics and allow the student do on the blackboard of being everlasting.Just need erase the board after having write on blackboard, present black and white all is to wipe manual erase with black and white, seems very inconvenient, and chalk dust can be stained with to hand, on one's body, waft to such an extent that be everywhere, very unhygienic, injury skin, more seriously some chalk dusts are by in people's inspiration lung, must go up tuberculosis easily.

Summary of the invention

In order to address the above problem, the invention provides a kind of simple and convenient, health blackboard device of being easy to realize.

A kind of health blackboard device comprises blackboard panel, and blackboard panel is provided with track in two ends up and down; The brush that vertically becomes mildewed is installed on the blackboard panel; Become mildewed the brush two ends pulley is installed; Track place, lower end is equipped with blackboard groove and dust catcher; Dust catcher is installed in the blackboard groove; The blackboard groove is a trough type, groove depth, and lower bottom cover can be opened flexibly; Dust catcher is made up of motor and fan leaf.

Advantage of the present invention is that easy to use flexible, sanitation and hygiene are installed simply, can not damage the healthy of user.

Description of drawings

Fig. 1 is a health blackboard device schematic diagram of the present invention.

The specific embodiment

As shown in Figure 1, a kind of health blackboard device, bag blackboard panel 5, blackboard panel are standing to be installed on the wall, and it is provided with pulley track 21,22 in both sides up and down.The become mildewed brush 3 the same with blackboard eraser vertically is installed on the blackboard panel, the brush that becomes mildewed is an integral body, and be dismountable, the convenient cleaning and replacing, can pin the brush that becomes mildewed with hand during use erases the board, the moving of brush of becoming mildewed is very flexible, can move to the left side or the right of blackboard panel when not in use, can not hinder on blackboard and write.The hairbrush two ends respectively are equipped with a pulley 11,12.Pulley 11,12 cooperates with blackboard track 21,22 respectively, and pulley can be free to slide in orbit, reduces hairbrush 3 and the blackboard panel friction at two ends up and down.At blackboard track 22 places dust catcher 4 and blackboard groove are installed, the blackboard groove is made trough type, and it is dark that groove is wanted, and the bottom of groove can open, and when the chalk dust in the blackboard groove is too much, can opens bottom and clear up chalk dust.Dust catcher 4 is installed in the blackboard groove, dust catcher 4 is made up of motor and fan leaf, rotate by motor operations, drive the work of fan leaf, chalk dust is produced downward attraction, simultaneously, chalk dust itself also has gravity, so can enter very soon in the blackboard groove under to the effect of its downward attraction at the gravity of chalk dust own and dust catcher 4, can not waft to other places, more can be by in user's inspiration lung.In the concrete use, can decide the quantity of dust catcher according to the length of blackboard, they all are installed in parallel in the blackboard groove, and motor also all is in parallel, by a switch control.When large tracts of land erases the board, earlier dust catcher is opened, erase the board with the brush that becomes mildewed then, when small size erases the board, can wipe the cooperation dust catcher with common black and white and erase the board, convenient and sanitary like this.

Generally speaking, health blackboard of the present invention is to install the hairbrush that is similar on the blackboard eraser on long blackboard eraser, and this hairbrush is an integral body, and is demountable, cleaning and replacing that like this can Convenient brush.A pulley is respectively installed at the two ends of long blackboard eraser, blackboard be up and down track, the size of track just in time can allow pulley slide in track.The purpose that pulley is installed is to reduce long blackboard eraser and the blackboard friction at two ends up and down.So just can pin long blackboard eraser with hand erases the board.Moving of long blackboard eraser is very flexible, when time spent not can move to the left side or the right of blackboard, does not write and can not hinder.Dust catcher is mounted in the position of blackboard groove, it can be with in the chalk dust inspiration blackboard groove, chalk dust can enter into the blackboard groove at self gravitation and dust catcher under to the effect of its downward suction very soon like this, and can not waft to other places, more can be by in teacher's inspiration lung.Dust catcher adds that with motor the fan leaf makes.The blackboard groove will be made long trough, and it is dark that groove is wanted, and dust catcher just is installed in the blackboard groove.The bottom of blackboard groove is openable, can open the bottom of blackboard groove and clear up chalk dust when the chalk dust in the blackboard groove is too much.Motor all is in parallel, controls them by a switch.Dust catcher also can use flexibly, and the quantity of motor can increase according to the length of blackboard or reduce.When large tracts of land erased the board, we can open dust catcher earlier, erased the board with long blackboard eraser then; When small size erased the board, we erased the board with common blackboard eraser.Convenient and sanitary like this.
