[0026] Reference Figure 1-3 This utility model provides a zero-emission air circulation unit, comprising:

[0027] The main unit 100 includes a body 101, on which a return air duct 102 and an air supply duct 103 are fixedly connected. The return air duct 102 and the air supply duct 103 are arranged symmetrically up and down, which facilitates the circulation and transportation of air.

[0028] The filter unit 200 includes a partition 201 fixedly connected inside the body 101. Two filter plates 202 are movably connected to the body 101, and concave plates 203 are fixedly connected to both filter plates 202. A heat exchanger 204 is installed inside the body 101. A limiting component 205 for fixing the filter plates 202 is installed on the body 101. An airflow guiding component 206 is installed inside the body 101 to guide airflow. The partition 201 can separate the filter plates 202 from the heat exchanger 204, providing a flow path for the air and preventing untreated outdoor air from bringing pollutants into the room. The circulating air is filtered by the filter plates 202 on both sides, improving the quality of the circulating air. The heat exchanger 204 can quickly and effectively transfer heat or cold during air circulation, improving energy utilization efficiency. The heat exchanger 204 is existing technology and will not be described in detail here.

[0029] The limiting component 205 includes a perforated plate 205a, which is fixedly connected to the body 101. A crossbar 205b is fixedly connected to the perforated plate 205a. Insert blocks 205c are slidably connected to both sides of the crossbar 205b. Pull rods 205d are fixedly connected to both insert blocks 205c. Springs 205e are sleeved on both sides of the crossbar 205b. The extension and retraction of the springs 205e can connect the insert blocks 205c to the concave plate 203, thereby limiting the filter plate 202 and preventing it from loosening during filtration. It also facilitates the user to remove and maintain the filter plate 202 regularly. When removal is required, the filter area of ​​the filter plate 202 can be removed by pulling the pull rods 205d together. The same operation can also put the filter plate 202 back into the body 101.

[0030] Furthermore, the airflow guiding component 206 includes an air duct 206a, which is fixedly connected to the partition 201. An electric fan 206b is rotatably connected to the inner wall of one side of the body 101. The air duct 206a and the electric fan 206b can assist the air to circulate along the internal flow path of the body 101, preventing the air from being blocked and affecting the use of the body 101.

[0031] Furthermore, both inserts 205c are connected to the corresponding recesses 203. The two ends of the two springs 205e are fixedly connected to the orifice 205a and the inserts 205c respectively. The inserts 205c can be connected to the recesses 203 to restrict the recesses 203. The fixed ends of the springs 205e can prevent them from bending under pressure and ensure the stability of the springs 205e in use.

[0032] Furthermore, the two filter plates 202 are a metal mesh plate and an activated carbon plate, respectively. A baffle is movably connected to the body 101. The metal mesh plate can first intercept larger impurities in the air, and then the activated carbon plate can adsorb smaller impurities, thereby improving the air quality through a dual filtration effect. The baffle is movable, which facilitates maintenance and repair of the body 101 and prevents the equipment from failing to open due to malfunction.

[0033] Furthermore, a bracket 207 is fixedly connected to the bottom surface of the body 101. Multiple support rods 208 are fixedly connected to the side of the bracket 207 away from the body 101. The bracket 207 can assist in supporting the body 101, preventing ground dust from directly contacting the body 101 and affecting the use of the equipment. The support rods 208 can also improve the stability of the equipment.

[0034] During use, air circulation is achieved through the return air duct 102 and the supply air duct 103. The filter plate 202 is separated from the heat exchanger 204 by the partition plate 201, providing a flow path for the air. The air circulates along the internal flow path of the unit 101 with the assistance of the air duct 206a and the electric fan 206b, thus preventing untreated outdoor air from bringing pollutants into the room. The circulating air is then filtered by the filter plate 202 to improve the quality of the circulating air. At the same time, the extension and retraction of the spring 205e connects the insert block 205c to the concave plate 203, thereby restricting the filter plate 202 and preventing it from loosening. This also facilitates the regular removal and maintenance of the filter plate 202, making it convenient and quick.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
