However, the ventilation device cannot filter the outside air, so that the air replaced into the room contains pollutants such as solid particles, and the influence on the health is caused.

SUMMERY OF THE UTILITY MODEL

This scheme provides an intelligent breather of building to solve current air filter and can't carry out filterable problem to the solid particle thing in the contaminated air.

In order to achieve the purpose, the scheme provides an intelligent building ventilation device which comprises a shell and a fan, wherein an air inlet and an air outlet are formed in the shell, the fan is arranged in the shell through a first rotating shaft, a filter screen is arranged between the fan and the air outlet, the first rotating shaft is connected with a motor, and a first bevel gear is arranged on the first rotating shaft;

still include second pivot, second bevel gear and cylinder, second bevel gear meshes with first bevel gear mutually, still be equipped with the cam in the second pivot, cam intermittent type nature striking cylinder's piston rod, be equipped with reset spring in the cylinder, reset spring one end and piston connection, reset spring one end is connected bottom the cylinder, be equipped with inlet duct and the pipeline of giving vent to anger on the cylinder, be equipped with the check valve that admits air on the inlet duct, be equipped with the check valve of giving vent to anger on the pipeline of giving vent to anger, be equipped with out the dirt mouth on the casing, it is connected with the filter screen to go out the dirt mouth, inlet duct and play dirt mouth intercommunication, be equipped with the laying dust bag on the inlet duct.

The principle of the scheme is as follows: when needs are to change fresh air indoor, open the motor for the fan rotates and inhales indoor air in the casing, then filters the solid particle in the air through filter equipment, and then the air after the filtration is discharged from the air outlet on the casing indoor, and then indoor air changes the completion.

Meanwhile, the motor rotates to drive the first rotating shaft to rotate, the first rotating shaft rotates to drive the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second rotating shaft rotates to drive the cam to rotate, the cam rotates and then intermittently impacts a piston rod of the air cylinder, the piston moves back and forth under impact of the cam and acting force of a reset spring, the air cylinder further makes air inlet and air outlet movement through the air inlet pipeline and the air outlet pipeline, dust filtered by the filter screen enters the dust outlet, when the air cylinder inhales air, the dust is sucked into the air suction pipeline, and then dust is collected by the dust bag. The filter screen keeps a clean state all the time, and the air outside the filter screen can be better filtered.

The beneficial effect of this scheme does:

1. the filter screen is arranged in the shell, so that solid particles in the air can be well filtered, the air outlet of the air interchanger is prevented from being blocked, and the using effect of the air interchanger is improved; meanwhile, the quality of the filtered air is improved, and great benefit is brought to the health of human bodies.

2. Through setting up bevel gear and cylinder for breather when taking a breath, the dust on the filter screen gets into out the dirt mouth, then is inhaled in the laying dust bag by the admission line of cylinder, makes the interior filterable dust of breather can in time discharge from breather, makes breather's ventilation effect better, comes simultaneous drive fan pivot and cylinder to breathe in through the motor moreover, and the energy saving is very environmental protection.

Further, the dust bag is detachably mounted on the air inlet duct. When the dust collecting bag is full of dust, the dust collecting bag can be taken down when the air is not exchanged, and then the dust collecting bag is installed after being cleaned, and the dust is collected continuously.

Further, it is equipped with the fly leaf to slide on the pipeline of giving vent to anger, be equipped with the through-hole that is used for giving vent to anger on the fly leaf, the fly leaf passes through second reset spring and connects in the pipeline, be connected with the scraper blade on the fly leaf, the scraper blade is used for striking off the dust on the filter screen, the casing is passed in the scraper blade slides. When the cylinder is giving vent to anger, because the through-hole is less, and then the air current of giving vent to anger of cylinder is greater than the air current of through-hole circulation, and then the cylinder row can promote the fly leaf and move forward, and second reset spring is tensile this moment, and then promotes the scraper blade and down scrape along the filter screen, and then scrapes the dust on the filter screen down for in the dust gets into out the dirt mouth, when the cylinder admits air, second reset spring resumes the fly leaf to initial position.

Further, the top end of the scraper is in an inverted L shape. The side of the scraper plate perpendicular to the filter screen is used for scraping off dust on the filter screen, and the side parallel to the filter screen is used for resisting wind of the exhaust fan, so that the dust scraped by the wind is prevented from being blown into the device.

Further, the scraper blade is made of rubber materials. The scraper blade that the rubber material was made can not cause the damage to the filter screen, has guaranteed the integrality of filter screen.

Further, a sterilization device is arranged in the shell. The filtered air can be sterilized to improve the purification effect.

Further, the sterilizing device is an ultraviolet lamp, and the ultraviolet lamp is a UVC-LED lamp. The UVC-LED lamp is selected as the ultraviolet lamp, and the broad-spectrum and high-efficiency sterilization effect can be achieved.
