Abstract

The application provides a fresh air purification window for preventing haze. A ventilation device is provided with an upper layer and a lower layer and partitioned by a transverse middle-layer partition plate, an exhaust fan is mounted in the upper layer, an air feeder is mounted in the lower layer, an air inlet grille is formed on the upper layer through front-layer glass, and a half-closed space with an air cavity unidirectionally provided with an exhaust opening is formed by the upper layer, upper-layer glass, a middle-layer separation partition plate and air cavity one-sided glass. The fresh air purification window has the effects of lowering the shielding light ray of the current purification window and enabling the current purification window to be compact in structure.

First claim

What is claimed is:

1. A fresh air purification window for anti-haze, comprising a space formed by a front layer of glass and a rear layer of glass, wherein the front layer of glass is indoor glass, and the rear layer of glass is outdoor glass; an air cavity is formed between the two layers of glass; an air exchange device with glass and openings is formed near a center of the air cavity; the air exchange device includes upper and lower layers separated by a horizontal middle partition plate; an air exhaust fan is installed in the upper layer, and an air supply fan is installed in the lower layer; in the upper layer, the front layer of glass forms an air intake grille, and a semi-closed space of the air cavity having a one-way air outlet is formed with the upper layer glass, the middle layer partition plate, and one side glass of the air cavity; in the lower layer, the rear layer of glass forms an air intake grille, and a semi-closed space of the air cavity having a one-way air inlet is formed with the lower layer glass, the middle layer partition plate, and one side glass of the air cavity; wherein the one side glass of the air cavity is installed at the left or the right side, and the one side glass of the air cavity in the upper layer and the one side glass of the air cavity in the lower layer are installed in a left-right direction; and the air outlet in the upper layer and the air inlet in the lower layer are installed in a left-right direction; at outdoor side of the rear layer of glass in the lower layer, a spray nozzle is installed at the glass near the top of the middle partition plate; an inner layer of the air intake grille of the rear layer of glass in the lower layer is installed with a filter screen; for the front and the rear layers of glass at a side opposite to the air inlet in the lower layer, the rear layer of glass is installed with an outer shutter in an air supply cavity by a rotating shaft for an outer shutter in an air supply cavity, and the front layer of glass is installed with an inner shutter in the air supply cavity by a rotating shaft for an inner shutter in the air supply cavity; for the front and the rear layers of glass at a side opposite to the air outlet in the upper layer, the rear layer of glass is installed with an outer shutter in an air exhaust cavity by a rotating shaft for an outer shutter in an air exhaust cavity, and the front layer of glass is installed with an inner shutter in the air exhaust cavity by a rotating shaft for an inner shutter in the air exhaust cavity; the connection by the rotating shaft for the shutter is provided such that a respective shutter is open to connect to the indoor or outdoor space.

2. The fresh air purification window for anti-haze of claim 1 , wherein each of above shutters is installed at corresponding end of glass and each of above rotating shafts is installed at corresponding window frame, such that the corresponding glass and window frame are connected via corresponding shutter.

3. The fresh air purification window for anti-haze of claim 1 , wherein a hinge shaft of each shutter for air exhaust and air supply is connected to a stepping motor; a PM2.5 sensor for monitoring a concentration of a pollutant and a solar panel for supplying the electric energy are disposed outside the fresh air purification window for anti-haze; the stepping motor and the PM2.5 sensor are connected to a control system.

4. The fresh air purification window for anti-haze of claim 1 , wherein the spray nozzle is a high pressure spray nozzle that is connected to an indoor water supply pipe.

5. The fresh air purification window for anti-haze of claim 1 , further comprising a cloud server, an APP, and a WIFI module; a PM2.5 sensor transmits collected data to the APP through the cloud server, and signals in a corresponding mode selected by the user according to the data are transmitted to the cloud server through the APP, and the cloud server transmits control signals for starting motors to the motors through the WiFi module, the control signals is used for controlling the controlled starting or closing of the motors of four shutters and two fans.
