The present invention relates to the technical field of air purification, and particularly relates to an air purification apparatus for an indoor window vent.
Air purifier is also called as an “air cleaner”, and refers to a product that can absorb, decompose or convert various air pollutants (generally including decoration pollutants such as dust, pollen, undesirable odor and formaldehyde, bacteria, allergen, etc.) and can effectively enhance air cleanness. At present, some air purifiers can realize purification of indoor air, but have high cost and large volume and do not allow to open a window. Such purifiers cannot convect and exchange the indoor air and outside air. Although the indoor air is purified, because the indoor air cannot convect and exchange with the outside air, the content of indoor oxygen is reduced, which is not favorable for human health. Thus, an air purification apparatus for an indoor window vent is proposed.
The purpose of the present invention is to propose an air purification apparatus for an indoor window vent in order to solve disadvantages in the prior art.
To achieve the above purpose, the present invention adopts the following technical solution:

Preferably, the isolating plate comprises a flexible transparent plastic plate and two connecting bands; both sides of the flexible transparent plastic plate are connected with the connecting bands; the connecting bands are hollow structures; and magnet particles are filled in the connecting bands.
Preferably, two sealing strips are embedded into the side wall of one side of the installing plate; and the sealing strips are respectively located on both sides of the air purification module.
Preferably, an opening is formed in the top side wall of the air duct; a cover plate is hinged at the opening; sliding chutes are formed in the top inner wall and the bottom inner wall of the air duct; and both ends of the cleaning brush are respectively connected into the sliding chutes in a sliding mode.
Preferably, a vertical section of the air duct is rectangular.
Preferably, a temperature sensor, a carbon dioxide concentration sensor and a controller are installed on the installing plate; an input end of the controller is connected with a power supply, the temperature sensor and the carbon dioxide concentration sensor; and an output end of the controller is connected with the first fan and the second fan.
Preferably, a sealing ring is arranged on a connecting part between the sealing block and the air outlet cylinder; the sealing ring is embedded on the sealing block; the sealing block (13) is connected with two guiding rods; two guiding grooves are formed in the air outlet cylinder; and guiding blocks are connected into the guiding grooves in a sliding mode.
The present invention proposes an air purification apparatus for an indoor window vent. Through the arrangement of the fixing blocks, the air purification module, the installing plate, the placing cavities, twisting rollers, the discharging ports, the positioning block, the magnet block, the isolating plate and the first volute spring, window vents with different sizes can be sealed; outdoor air is guided into the room for ventilation; and meanwhile, the air that enters the room during ventilation is purified, thereby reducing the entering amount of outside air pollutants.
Through the arrangement of the second fan, the sealing block, the guiding rods, the second springs, the dustproof net and the air outlet cylinder, indoor vitiated air can be guided out of the room without passing through the air purification apparatus, thereby reducing loss of material in the air purification apparatus.
Through the arrangement of the controller, the temperature sensor and the carbon dioxide concentration sensor, when the apparatus senses that indoor temperature is high or carbon dioxide concentration is too high, ventilation and heat dissipation can be realized automatically. The apparatus can seal window vents with different sizes without affecting the opening and closing of windows, can purify air that enters a room, has good purification effect and also has the function of automatic ventilation and heat dissipation.

With reference to
Embodiment: During use, the installing plate 3 is fixed to the window vent through the installing holes in the fixing blocks 1, and is fixed through screws. During ventilation, the window is opened; two positioning blocks 7 are pulled so that the positioning blocks 7 continuously pull out the isolating plate 9; the volute spiral spring 10 is driven and tightened; and the magnet block 8 on the positioning block 7 is absorbed to a frame of the window. Meanwhile, the magnet particles in the connecting band 93 on the isolating plate 9 are absorbed to the frame of the window so that the flexible transparent plastic plate and the window are kept sealed. The first fan 26 is started. The air outside the first fan 26 is guided into the room. Dust odor in the air is removed through the filter mesh 21, the active carbon filtering unit 24 and the PM2.5 purification unit 25. The purification effect is excellent. After use for a period of time, the pull ring 29 is pulled. The pull ring 29 drives the cleaning brush 22 through the connecting rope 28 to slide in the air duct 23. The first springs 27 are stretched. The cleaning brush 22 removes dust accumulated on the filter mesh 21. The controller detects the indoor temperature and the carbon dioxide concentration at any time through the temperature sensor and the carbon dioxide concentration sensor. When the controller detects that indoor temperature or the carbon dioxide concentration is high, the second fan 12 is automatically controlled to start for guiding the indoor vitiated air out of the room. Meanwhile, the first fan 2 is started for ventilating and guiding the outdoor air into the room through the air purification apparatus 2. The apparatus can seal window vents with different sizes without affecting the opening and closing of windows, can purify air that enters a room, has good purification effect and also has the function of automatic ventilation and heat dissipation.
