DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are involved in the protection scope of the present application.

[0020] The existing device covers a narrow range from the spray head to the house, which affects the ventilation effect of the edge space. The main reason is that the air sprayed by the spray head usually has a fixed direction and strong speed, which leads to the rapid concentration of air in the room and cannot be evenly diffused to the edge of the house. In this way, the edge area of the house cannot obtain sufficient air flow, affecting the ventilation effect of these areas. Please refer to Figures 1-4The embodiment provides a ventilation device for house engineering construction, which comprises an air outlet channel 2 fixedly communicated with the side of a mounting plate 1, an air diffusion assembly 4 arranged on the side of the air outlet channel 2 away from the mounting plate 1, the air diffusion assembly 4 comprising a flow guide cylinder 41 rotatably arranged on one side of the air outlet channel 2, two swing assemblies 42 arranged on the two sides of the air outlet channel 2 and used for driving the flow guide cylinder 41 to reciprocate, the swing assembly 42 comprising a circular plate 421 rotatably arranged on one side of the air outlet channel 2, a sliding rod 422 fixedly arranged on the side of the circular plate 421 away from the air outlet channel 2, one end of the flow guide cylinder 41 being fixedly connected with a linkage plate 423, and the inner wall of the linkage plate 423 being provided with a sliding groove 424 for the sliding rod 422. The air outlet channel 2 is internally provided with a power assembly 43 used for providing driving force for the two swing assemblies 42, the power assembly 43 comprising a rotating shaft 431 fixedly arranged on the inner wall of the circular plate 421, and a plurality of windward leaves 432 annularly and equidistantly arranged on the outer wall of the middle end of the rotating shaft 431. The outer wall of the flow guide cylinder 41 is provided with an air inlet groove, the inner wall of the air inlet groove is provided with a plurality of air flow channels 44, the directions of the plurality of air flow channels 44 are different, and the plurality of air flow channels 44 are communicated with the air outlet channel 2 through the air inlet groove. The mounting plate 1 is bolted at the air inlet of the house, then a wind pump is started according to the prior art, the external air is sucked into the house, and is filtered through the filter screen 3, so that the air entering the house is clean. The process ensures the quality of air circulation and improves the indoor air quality. After the air enters the air outlet channel 2, the air flows out through the plurality of air flow channels 44 in the flow guide cylinder 41. The directions of the plurality of air flow channels 44 are different, so that the flow direction of the air is changed, thereby increasing the coverage range of the air. The design effectively enhances the diffusivity of the air in the room, especially the coverage effect of the edge space of the house. When the air in the air outlet channel 2 flows, the windward leaves 432 are blown, which drives the rotating shaft 431 to rotate, and then drives the circular plate 421 to rotate. The rotation of the circular plate 421 makes the sliding rod 422 slide in the sliding groove 424, and then makes the linkage plate 423 swing. The movement drives the flow guide cylinder 41 to reciprocate by a small amplitude, further optimizes the distribution of air flow, and makes the air more uniformly cover the room, especially the edge area. Through the reciprocating rotation of the flow guide cylinder 41, the direction and speed of the air flow are dynamically adjusted, so that the air can cover a wider area, especially the edge area which is usually difficult to obtain sufficient ventilation. The design not only improves the air circulation of the whole room, but also enhances the ventilation effect of the room, ensures that each area can obtain sufficient fresh air, effectively improves the uniformity and diffusion effect of air coverage, ensures that the edge space of the house can also be fully ventilated, and improves the air quality and comfort in the room.

[0021] As Figure 3As shown, the inside of the mounting plate 1 is fixedly installed with the filter screen 3 through buckling, the outer wall of the rotating shaft 431 is provided with a anti-blocking assembly 45 for knocking the filter screen 3, the anti-blocking assembly 45 includes two rubber rods 451 fixed symmetrically on the outer wall of both ends of the rotating shaft 431, and the two rubber rods 451 are in contact with the filter screen 3 when rotating. When the rotating shaft 431 rotates, the rubber rod 451 also rotates. The rubber rod 451 vibrates and cleans the filter screen 3 through continuous knocking action when rotating. This vibration effect can help loosen and remove dust, debris and tiny particles accumulated on the filter screen 3. The softness and elasticity of the rubber rod 451 are the key to this design. It can effectively remove dust on the filter screen 3 through slight knocking and vibration effect, and will not cause damage to the filter screen 3 itself. This is because the rubber material has a certain flexibility, which can form a certain buffer during contact to avoid excessive pressure or friction on the surface of the filter screen 3 caused by hard objects, thereby ensuring the long-term use and cleaning effect of the filter screen 3. It can prevent the filter screen 3 from being blocked due to the accumulation of dust and debris, ensure the air flow of the air pump is not affected, and thus maintain the air flow effect and good ventilation state. At the same time, the cleaning effect of the rubber rod 451 prolongs the service life of the filter screen 3, reduces the maintenance and replacement frequency, and improves the stability and operating efficiency of the system. Through the continuous knocking and vibration cleaning effect of the rubber rod 451, the filter screen 3 is always clean, ensuring that the device can operate efficiently and stably, providing continuous air flow and purification function.

[0022] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
