Description

Technical Field

[0001] The present invention relates to the field of ventilation facilities, in particular to energy-saving filtering ventilation equipment with a self-cleaning function. Background Art

[0002] As a key facility for modern air quality control, ventilation equipment's core operating mechanism is based on the principles of aerodynamics. High-speed fans within ventilation ducts generate powerful airflows, creating an air pressure differential that forces air circulation, enabling efficient exchange of indoor and outdoor air or continuous air circulation within a specific space. This air exchange mechanism not only effectively introduces fresh air and removes turbid gases, moisture, and harmful pollutants from indoor spaces, but also regulates the temperature and humidity within the space, creating a healthy and comfortable air environment. Due to its powerful functions, ventilation equipment is widely used in various fields such as construction, healthcare, industry, and transportation, becoming a core facility for ensuring air quality in various scenarios.

[0003] During the actual use of ventilation equipment, in order to ensure that the air entering the ventilation system is clean, a filter is usually installed at the air inlet of the ventilation duct to intercept dust, particulate matter and other impurities in the air to prevent impurities from entering the indoor space.

[0004] However, in areas where poplars, willows, and other tree species are widely planted, during the spring when the trees are shed, large amounts of light fluff are carried by the airflow toward the ventilation equipment. These fine fluffs easily adhere to the filter in a short period of time, quickly forming a thick layer of flocculent material. As the fluff accumulates, the pores of the filter gradually become clogged, significantly reducing air permeability and leading to a sharp decrease in air volume and severe damage to the ventilation system's effectiveness. Furthermore, to ensure the proper operation of the ventilation equipment, users must frequently manually clean the fluff from the filter, which not only consumes a lot of time and energy, but also increases labor intensity and causes significant inconvenience to users.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, multiple evenly distributed and bent guide seats can disperse and guide the air, allowing the air to fully contact the cotton cloth on the guide seat, allowing the tree wool in the air to be adsorbed on the cotton cloth. At the same time, water will enter the guide seat through the connecting pipe on the water inlet pipe and flow out from the through hole on the guide seat to moisten the cotton cloth, thereby increasing the adsorption force of the cotton cloth, firmly adsorbing the tree wool in the air, and preventing a large amount of tree wool from adhering to the filter screen, thereby ensuring good air permeability of the filter screen and improving the ventilation effect;

[0016] 2. In the present invention, the rotating shaft can drive the propulsion wheel to roll on the filter housing. At this time, the triangular groove on the propulsion wheel continuously engages with the triangular anti-slip protrusion to increase friction, allowing the propulsion wheel to move forward stably, thereby driving the cleaning sheet on the sheet rack to move onto the cotton cloth to scrape off the tree wool absorbed by the cotton cloth. The process does not require manual cleaning, effectively reducing labor intensity and facilitating use.

[0017] 3. In the present invention, when the shaft drives the propulsion wheel forward, it will also accelerate the rotation of the connecting ear on the paddle shaft, thereby driving the groove frame to move, so as to push the sheet frame, so that the cleaning sheet on the sheet frame continuously swings back and forth in a small amplitude to increase the cleaning force of the tree wool. At the same time, when the propulsion wheel moves forward, it will also drive the valve control tooth plate to move, thereby driving the valve control gear to rotate, so that the valve can be opened, so that water flows and continuously overflows from the cotton cloth. In this way, under the push of water, the tree wool attached to the cotton cloth is lifted up so that it can be scraped off by the cleaning sheet later, thereby ensuring that the tree wool is completely removed and the cleaning effect of the tree wool is guaranteed. At the same time, when the propulsion wheel moves backward, it will drive the valve control tooth plate to reset and drive the valve control gear to reverse to close the valve, thereby avoiding waste caused by continuous flow of water to ensure energy saving.

A shaft rod 33 is rotatably installed through the upper end of the L-shaped moving frame 15, and the shaft rod 33 extends from the lower end of the L-shaped moving frame 15.

[0033] The acceleration assembly includes two pulleys 29, which serve to connect the transmission belt 30. One of the pulleys 29 is coaxially embedded in the upper end of the paddle shaft 31, and the other pulley 29 is coaxially embedded in the outer surface of the shaft 33. The diameter of the pulley 29 on the shaft 33 is larger than the diameter of the pulley 29 on the paddle shaft 31, which can accelerate the rotation of the paddle shaft 31.

[0036] During ventilation, the driving motor 18 drives the ventilation fan 21 on the fan shaft 19 to rotate to force the air circulation for ventilation. In this process, the air will flow between the multiple guide seats 10, so that the air is dispersed and guided under the action of the multiple guide seats 10 that are evenly distributed and bent, so that the air can fully contact the cotton cloth 7 on the guide seat 10, so that the tree wool in the air can be adsorbed on the cotton cloth 7.

When the tree wool needs to be cleaned, the servo motor 3 will drive the shaft 33 to rotate, thereby driving the propulsion wheel 34 to roll on the filter housing 2. At this time, the triangular groove 38 on the propulsion wheel 34 is continuously engaged with the triangular anti-slip protrusion 37 to increase friction, allowing the propulsion wheel 34 to move forward stably, thereby driving the cleaning sheet 6 on the sheet rack 5 to move to the cotton cloth 7 to scrape the tree wool. During this process, the shaft 33 It will also accelerate the connection ear 22 on the paddle shaft 31 to rotate, thereby driving the groove frame 32 to move, so as to push the sheet frame 5, so that the cleaning sheet 6 on the sheet frame 5 continuously swings back and forth in a small amplitude to increase the cleaning force of the tree wool, so as to clean the tree wool. At the same time, when the propulsion wheel 34 moves forward, it will also drive the valve control gear plate 25 to move, thereby driving the valve control gear 24 to rotate, so that the valve 13 can be opened, so that water flows and continuously overflows from the cotton cloth 7, so that the tree wool attached to the cotton cloth 7 is lifted up under the push of water, so that it can be scraped off by the cleaning sheet 6 later. This ensures that the tree wool is completely removed and the cleaning effect of the tree wool is guaranteed. When the propulsion wheel 34 rolls to the end of its stroke, the servo motor 3 moves in the opposite direction to drive the propulsion wheel 34 to retreat, allowing the cleaning sheet 6 to scrape the tree wool on the cotton cloth 7 again. When the propulsion wheel 34 retreats to the end point, the valve control gear plate 25 will re-engage with the valve control gear 24 and drive the valve control gear 24 to reverse to close the valve 13, so that the water no longer flows. At the same time, the servo motor 3 stops rotating. At this time, the cotton cloth 7 is in a wet state under the action of water to absorb the tree wool in the air again, and this cycle continues.
