Technical Field

The invention relates to the technical field of curtains, in particular to a negative pressure adsorption curtain.

Background

The curtain is made of cloth, hemp, yarn, aluminum sheet, wood chip, metal material, etc. and has the functions of shading sun, insulating heat and regulating indoor light. The cloth curtain is divided into cotton gauze, polyester fabric, polyester-cotton blended fabric, cotton-hemp blended fabric, non-woven fabric and the like according to the material, different materials, textures, colors, patterns and the like are integrated to form cloth curtains with different styles, and the cloth curtains are matched with indoor design curtains with different styles.

Every indoor room mostly all need install the curtain, sleep at summer night and need windowing the ventilation sometimes, close the window for a long time and cause the discomfort easily, also not cool enough, and sometimes in order to guarantee the privacy when sleeping, can pull out the curtain, under windy circumstances, the curtain can be blown up, the privacy can not be ensured to the curtain also can produce certain noise under blowing of wind, influences the sleep.

Disclosure of Invention

The invention aims to solve the defects in the prior art, and provides a negative pressure adsorption curtain which can adsorb a curtain on a wall surface under the condition of wind so as to prevent the curtain from being blown up.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a negative pressure adsorbs (window) curtain, is including installing the (window) curtain in window and wall one side, the back of (window) curtain is equidistant to be fixed with many air-supply lines, the air-supply line is vertical to be set up, the bottom lateral wall of air-supply line is fixed with the fixture block, the lateral wall of wall is fixed with the stopper that corresponds with the fixture block, the front side of stopper is equipped with the draw-in groove with fixture block complex, be equipped with the negative pressure chamber in the fixture block, through the breathing pipe intercommunication between air-supply line and negative pressure chamber, the breathing pipe sets up with the air-supply line is perpendicular, the inner wall on the relative breathing pipe one side in negative pressure chamber is.

Preferably, the inner wall of the clamping groove is embedded with a sealing ring, and the sealing ring is tightly attached to the outer wall of the clamping block.

Preferably, the inner wall in wind channel is equipped with the semicircle groove, the inner wall in semicircle groove rotates and is connected with the pivot, the end of pivot is fixed with not closed metal frame, the inner wall that the semicircle groove is relative all is equipped with the arc magnetic sheet, two arc magnetic sheet opposite face heteropolar is inhaled mutually, forms magnetic field, not closed metal frame is located between two arc magnetic sheets, not closed metal frame is fixed with the blade with the parallel section of arc magnetic sheet, one side the blade extends to in the wind channel, two terminal elastic contact of not closed metal frame have the brush, be equipped with magnetism in the draw-in groove and inhale the mechanism.

Preferably, the magnetic attraction mechanism comprises a cylindrical electromagnet fixed on the inner wall of the clamping groove, an iron sheet corresponding to the cylindrical electromagnet is embedded at the front end of the clamping block, and the two electric brushes are connected with two ends of a coil of the electromagnet.

Compared with the prior art, the invention has the beneficial effects that:

1. through setting up air-supply line, fixture block and draw-in groove, can be under the windy condition, wind gets into the air-supply line along the (window) curtain, because the velocity of flow in the pipeline is very fast, and pipeline pressure is less to make negative pressure chamber form the negative pressure in the fixture block, inhale the air in the draw-in groove, thereby make the draw-in groove be in the negative pressure state, improve the adsorption affinity between fixture block and draw-in groove, thereby avoid the (window) curtain to be blown up.

2. Through setting up unclosed metal frame, arc magnetic sheet and magnetism and inhale the mechanism, can produce the electric current and supply power for the electro-magnet under the drive of wind to live with iron sheet absorption, further improve the adsorption affinity.
