[0051] The present invention provides a purification method for the above-mentioned gas purification device, comprising the following steps:

[0052] S1. The gas to be purified is input into the device through a special air inlet pipe 62, and then the gas passes through the long air holes 610 on the outside of the circular tube 67. These air holes have a specific shape and size so that the gas can smoothly enter the purification square plate 612. In the purification square plate 612, the gas contacts with a specific purification material and undergoes a preliminary purification process to remove most of the impurities therein;

[0053] S2. The gas after preliminary purification enters the molecular sieve cylinder 625 through the connecting hole 69 and the connecting port 611. The molecular sieve cylinder 625 is filled with efficient molecular sieve materials, which can remove tiny impurities and molecules in the gas. The top motor 65 is started, and the round tube 67 is driven to rotate through the thin rod 66. The central gear 615 is meshed with the peripheral gear 616. At the same time, the internal motor 621 inside the sleeve 618 is started, driving the internal fan 622 to rotate, generating airflow, helping the gas to be better dispersed and purified in the molecular sieve cylinder 625. At the same time, the refrigerator 624 is used to cool the gas inside the top cylinder 4. Lowering the temperature of the gas helps to improve its purity and stability, further improving the purification effect;

[0054] S3. When the top motor 65 drives the round tube 67 to rotate, the purification square plate 612 also rotates synchronously. This design enables the inner spring rod 71 to periodically squeeze the horizontal scraper 72. The horizontal scraper 72 performs cleaning work inside the device to remove impurities attached to the wall and components. The cleaned impurities enter the collection tank 75 in the receiving tank 74 through the opening 73 on the outside of the support platform 1, which is convenient for subsequent processing and discharge;

[0055] S4. When the sleeve 618 rotates, the connecting rod 620 drives the screen 81 to rotate. The rotation of the screen 81 helps to disperse the gas and remove impurities. The rotation of the thin rod 66 further drives the long plate 83 to rotate, and the round rod 84 drives the adsorption cylinder 88 to rotate. At the same time, the cooperation between the pinion 85 and the ring gear 86 enables the adsorption cylinder 88 to rotate while rotating. This composite motion enhances the adsorption effect. The adsorption cotton 811 in the adsorption cylinder 88 effectively collects impurities in the gas inside the device, thereby improving the purity of the gas.

[0056] S5. As the adsorbent cotton 811 continuously absorbs impurities inside the device, its weight will gradually increase. When the weight of the adsorbent cotton 811 reaches a certain threshold, it will squeeze the small spring rod 89 below, and then press the button 812. The pressing signal of the button 812 triggers the start of the servo motor 95, and the servo motor 95 drives the small fan 96 to start rotating. At the same time, the electric slide rail 97 drives the baffle 98 to move, generating airflow to help gas circulation. With the design of the elbow 93, the airflow inside the device can circulate quickly.

[0057] S6. The device continuously purifies the gas during continuous operation, and the purified gas is output to the subsequent system or environment through a special gas outlet pipe 64.

[0058] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
