DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] like Figure 1-4 As shown, a dust removal ventilation and air conditioning device proposed by the utility model includes a ventilation duct 1, a ventilation member 2, a filter 3, a cleaning component 4 and a spray component 5. The ventilation member 2 is arranged in the ventilation duct 1 to supply / exhaust air to the indoor space. The filter 3 is arranged on both sides of the ventilation member 2 and connected to the inner wall of the ventilation duct 1 at the same time, and is used to filter dust in the air. The cleaning component 4 is arranged on the filter 3 to scrape off the filtered material on the filter 3. The spray component 5 is arranged on one side of the filter 3 to spray water mist on the filter 3 so that the dust on the filter 3 condenses into flocs. The ventilation member 2 includes a connecting plate 21 connected to the inner wall of the ventilation duct 1; a motor 22 is arranged on the connecting plate 21; a connecting shaft 23 is connected to the driving end of the motor 22; the connecting shaft 23 passes through the connecting plate 21 and is rotatably connected to the connecting plate 21, and a rotating paddle 24 is connected to the other end. The rotating paddle 24 can be controlled to rotate forward or reverse by controlling the motor 22, thereby changing the wind direction blown by the rotating paddle 24. When the paddle 24 rotates forward, air can be supplied to the indoor space to achieve the effect of ventilation. When the paddle 24 rotates backward, dirty air in the room can be discharged, and dust in the room can also be discharged.

[0024] Further explanation, filters 3 are arranged on both sides of the ventilation element 2, which, on the one hand, filter the air discharged into the room to prevent dust in the external environment from entering the room and polluting the indoor air; on the other hand, filter the air discharged from the room to make the discharged air meet the emission standards. At the same time, the arrangement of two layers of filters 3 can enhance the filtering effect.

[0025] Further explanation, the cleaning assembly 4 includes fixed frames 41 arranged on both sides of the filter 3; the fixed frames 41 are connected to the inner wall of the ventilation duct 1, and threaded rods 42 are rotatably connected thereto; one end of the threaded rods 42 passes through the fixed frames 41 and is connected to the motor 2 43, and a connecting block 44 is also threadedly connected to the threaded rods 42; the connecting blocks 44 on both sides are commonly connected to two groups of scrapers 45; the two groups of scrapers 45 are respectively located on both sides of the filter 3, and the dust adhered to both sides of the filter 3 is cleaned at the same time. The filter 3 is cleaned more thoroughly to prevent the dust from blocking the filter holes of the filter 3 and causing the filter 3 to fail to work, thereby resulting in poor ventilation and dust removal effects.

[0026] Further explanation: a dust collecting box is provided at the lower end of the filter screen 3 for collecting the scraped dust to prevent the dust from scattering.

[0027] Further explanation, dustproof plates 47 are provided on both sides of the fixing frame 41. The dustproof plates 47 can block the gap at the fixing frame 41 to prevent dust from flying out from the gap of the fixing frame 41 without being filtered by the filter screen 3, thereby causing incomplete air filtration.

[0028] Embodiment 2

[0029] like Figure 2 and Figure 5 As shown, the dust removal ventilation and air conditioning equipment proposed by the utility model, compared with the first embodiment, this embodiment also includes: the spray assembly 5 includes a water tank 51 arranged on the ventilation duct 1; the water tank 51 is connected to a water pipe 52; the other end of the water pipe 52 is connected to a connecting seat 53; the connecting seat 53 is arranged on the inner wall of the ventilation duct 1, and a plurality of atomizing nozzles 54 are evenly arranged on it. The dust on the filter 3 can be condensed into flocs, so that when the dust on the filter 3 is scraped and cleaned, the dust will not be scattered by the scraper 45 and fly out, thereby causing new air pollution. And after the dust is condensed into flocs, it is not easy to adhere to the gaps in the filter 3, and the cleaning of the dust is also more thorough.

[0030] To further illustrate, the nozzle of the atomizing nozzle 54 faces the filter screen 3 and is tilted downward, so that the water mist received by the filter screen 3 is more uniform.

[0031] The working principle of the utility model is as follows: when ventilation is performed, the motor 22 is started and its driving direction is controlled, thereby controlling the rotating paddle 24 to rotate forward or reversely, thereby changing the wind direction blown by the rotating paddle 24. When the rotating paddle 24 rotates forward, air can be supplied to the indoor space to achieve the effect of ventilation. When the rotating paddle 24 rotates reversely, the dirty air in the room can be discharged, and the dust in the room can also be discharged.

[0032] When cleaning the filter 3, first start the water pump provided in the water tank 51, so that the water in the water tank 51 flows out along the water pipe 52 and the connection seat 53, and is sprayed out from the atomizing nozzle 54, so as to wet the dust adhering to the filter 3 and condense it into flocs. Then start the motor 2 43 to drive the threaded rod 42 to rotate, thereby driving the connecting blocks 44 on both sides to slide up and down along the threaded rod 42, and then driving the scraper 45 to move up and down on both sides of the filter 3, scraping the flocs adhering to the filter 3 into the dust box 46, and completing the cleaning of the filter 3. The dust adhering to both sides of the filter 3 is cleaned at the same time, so that the cleaning of the filter 3 is more thorough, and the dust is prevented from blocking the filter holes of the filter 3 and causing the filter 3 to fail to work, thereby resulting in poor ventilation and dust removal effects.

[0033] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
