A negative ion generator 8 is installed on the surface of the connecting plate 7, and the emission end of the negative ion generator 8 corresponds to the air intake end of the corrugated pipe 1.

[0026] Specifically implemented in this way, the emission end of the negative ion generator 8 corresponds to the air intake end of the corrugated pipe 1, ensuring that the air inhaled from the outside is purified by negative ions before entering the room, improving the purification efficiency; negative ions help improve the freshness of indoor air and are beneficial to aspects such as improving sleep quality, relieving stress, and improving work efficiency; the emission end of the negative ion generator 8 corresponds to the air intake end of the corrugated pipe 1, ensuring that the air inhaled from the outside is purified by negative ions before entering the room, improving the purification efficiency.

[0027] In order to realize the action of filtering dust and impurities from entering the room, the filtering mechanism 3 is provided with a filter screen 31. An air outlet hole 32 is opened at one end of the end cap 2, and a sliding groove 33 is opened on the inner side wall of the end cap 2. The sliding groove 33 and the air outlet hole 32 are coaxially arranged, and the inner wall of the sliding groove 33 is slidably inserted with the surface of the filter screen 31.

[0028] Specifically implemented in this way, the filter screen 31 can effectively intercept impurities such as dust, hair, and pollen in the air, prevent these pollutants from entering the room, keep the indoor air clean, and the cooperation between the filter screen 31 and the sliding groove 33 enables the reciprocating movement of the filter screen 31 to continuously clean the surface of the filter screen 31, prevent the filter screen 31 from being blocked due to dust accumulation, and maintain the filtration efficiency.

[0029] Insertion holes 34 are formed on the surface of the filter screen 31, and the four insertion holes 34 are distributed in a circular array on the surface of the filter screen 31. A limiting rod 35 is slidably inserted into the inner wall of the insertion hole 34, and one ends of the four limiting rods 35 are fixedly installed on the inner bottom wall of the sliding groove 33.

[0030] Specifically implemented in this way, the design of the insertion hole 34 and the limiting rod 35 ensures the precise alignment of the filter screen 31 in the sliding groove 33 and prevents the filter screen 31 from shifting during movement; the circular array distribution of the insertion holes 34 ensures that the force received by the filter screen 31 during movement is uniform, which helps to extend the service life of the filter screen 31.

[0031] The other end of the limiting rod 35 is also fixedly installed with a limiting plate 36. The limiting plate 36 is located on one side of the filter screen 31.

[0037] This device ensures the indoor and outdoor air circulation through the one-way air intake through the wall, while preventing outdoor pollutants from entering the room and keeping the indoor air fresh; the intake air uses the functions of negative ions to purify the air, remove odors, kill bacteria, etc., which can improve the indoor air quality and is beneficial to human health; it can also effectively filter pollutants such as dust, pollen, and bacteria in the outdoor air to ensure the indoor air quality; and during the filtering process, the reciprocating motion of the filter screen 31 is used to avoid the filter screen 31 being blocked by adsorbed dust, improve the service life of the filter screen 31, enhance the filtering effect, and the variable-frequency pure copper motor has strong power, stable operation, and low noise.

The negative ion generator 8 works to purify the air, remove the air odor, and kill the air bacteria, and then enters the room after being filtered by the filter screen 31. During the filtering operation, the driving motor 39 works to drive the cam 311 to rotate, and the cooperation of the cam 311 squeezing the filter screen 31 and the spring 37 is used to realize the reciprocating motion operation of the filter along the axis direction of the limiting rod 35.
