[0002] Existing air purifiers mainly consist of three parts: a filter module (HEPA filter), an ultraviolet (UVC) disinfection module, and an activated carbon adsorption module. The main function of the HEPA filter module is to intercept particulate matter (PM2.5, pollen, bacteria, etc.) through its ultra-fine fiber mesh. The main function of the UV disinfection module is to destroy the DNA / RNA of microorganisms, thus deactivating them. The main function of the activated carbon adsorption module is to adsorb gaseous pollutants such as formaldehyde and odors through its porous structure.

A slot 15 is provided below the groove 14. The handle 3 includes a fastener, which is connected to the upper housing through a rotating shaft. A torsion spring is provided between the fastener and the rotating shaft. The lower end of the fastener cooperates with the slot 15 to achieve locking. An electrical control device is also provided inside the top module 1. The electrical control device is electrically connected to the fan 5 and the plasma disinfection module 7.

[0021] The first embodiment of this utility model is as follows: A portable air purifier includes a bottom module 2 and a top module 1 that can be inserted into the bottom module 2 from above. The lower half of the top module 1 is an insert 11 that can be inserted into the lower housing, thus making the outer surfaces of the upper and lower housings flush and improving the aesthetics of the structure. Corresponding positions of the bottom module 2 and the top module 1 are provided with automatic locking components that cooperate to lock the bottom module 2 and the top module 1 together. The automatic locking components include a handle 3 located on the lower part of the upper housing and a component located on the upper part of the lower housing corresponding to the handle 3. The fitting groove 14 has a slot 15 at its bottom; the handle 3 is a push-button buckle handle 3, including a fastener. The fastener is connected to the upper housing through a pivot. A torsion spring is provided between the fastener and the pivot. The torsion spring causes the lower end of the fastener to tend to rotate towards the lower housing. The lower end of the fastener cooperates with the slot 15 to lock. At the same time, when the handle 3 is pressed, the fastener can be pushed to rotate in the opposite direction, so that the lower end of the fastener is disengaged from the slot 15, thereby unlocking. At this time, the top module 1 and the bottom module 2 can be separated.

[0022] An air intake assembly is provided on the lower outer surface of the bottom module 2. The air intake assembly includes an air intake grille 13 on the outer surface of the lower housing. Several air intake holes 10 are evenly arranged on the air intake grille 13. The air intake holes 10 are connected to the internal space of the lower housing. Larger impurities such as lint can be filtered through the air intake grille 13 and the air intake holes 10, which can achieve the first step of filtration.

[0023] The bottom module 2 has a pluggable annular filter element inside. The lower part of the lower housing has an annular groove, which the annular filter element can be inserted into to complete the installation. This allows for convenient and quick replacement of the annular filter element, which can perform a second-stage filtration to remove impurities from the air.

[0024] The top module 1 is provided with an exhaust port 4. The top module 1 is provided with an air duct assembly. The frame 16 of the air duct assembly is installed inside the upper housing by bolts. The lower end of the frame 16 is provided with an annular structure that is adapted to the annular filter 9 and engages with the annular filter 9. On the one hand, it can stabilize the annular filter 9, and on the other hand, it can seal the air duct to prevent air leakage. Furthermore, a sealing gasket is provided at the lower part of the annular structure to enhance the sealing between it and the annular filter 9.

[0025] The air duct assembly includes a fan 5, a catalyst filter element 6, and a plasma disinfection module 7, which are arranged sequentially from top to bottom inside the frame 16. The plasma disinfection module 7 includes a base support 178 with an annular grid structure. A plasma disinfection device is installed in the middle of the base support 178 by bolts. The plasma disinfection device can generate plasma to achieve sterilization. The annular grid structure of the base support 178 can physically restrict the airflow through the plasma disinfection module 7, increase the probability of contact between the air and the plasma disinfection module 7, and improve the disinfection and sterilization efficiency.

[0026] A pull-out groove is provided in the middle of the frame 16, and a pull-out box 12 that can be pulled out from the side is provided in the upper housing corresponding to the pull-out groove. The catalyst filter element 6 is provided inside the pull-out box 12, so that the catalyst filter element 6 can be quickly replaced without disassembling the air duct assembly.

[0027] A cross-shaped support 17 is provided on the upper part of the frame 16, and the support 17 is connected to the fan 5. The fan 5 generates an upward airflow to achieve the function of disinfecting and purifying the air.

[0028] The top module 1 also houses an electrical control device, which is electrically connected to the fan 5 and the plasma disinfection module 7. It also includes a power cord and a transformer, both electrically connected to the control device. The control device manages functions such as controlling the fan 5 speed, the plasma disinfection module 7's operating power, and setting timers for on / off cycles. The control device also includes sensors to identify the air purification index.

[0029] The difference from existing products lies in the use of plasma disinfection technology instead of ultraviolet disinfection. Air, drawn by the fan 5, first passes through an annular filter element through the air inlet of the lower casing, intercepting and filtering particles with a diameter ≥0.3 micrometers. The filtered air then passes through the internal air duct and next through the plasma disinfection module 7. This device kills microorganisms and decomposes pollutants by ionizing the air to generate highly active substances. During the destruction of microorganisms, the plasma releases ozone. The disinfected air then passes through the air duct and through a catalyst filter element 6. The catalyst filter element 6 adsorbs ozone onto its surface, which decomposes it into oxygen through an oxidation reaction. The disinfected and purified air, drawn by the fan 5 and aided by the air duct, is finally discharged from the exhaust port 4 at the top of the equipment.
