[0038] In some embodiments, as shown in FIGS. 3, 4, 8 and 9, the filter screen assembly includes a first filter screen 25 arranged on the side wall of the cyclone cone 22 and a second filter screen 26 arranged in the filtering channel 24. The air outlet of the second filter screen 26 is communicated with the lower opening of the machine body 11, so that the cyclone airflow is filtered by the first filter screen 25 and the second filter screen 26 in sequence and then discharged to the lower opening of the machine body 11.

[0039] The first filter screen 25 can be located outside the second filter screen 26, and part of the filtering channel 24 is formed between the first filter screen 25 and the second filter screen 26. The height of the second filter screen 26 can be less than the height of the cyclone cone 22, so that a gap is formed between the bottom of the second filter screen 26 and the bottom of the cyclone cone 22 for storing dust particles in the rotating airflow in the filtering channel 24.

[0040] A support member matched with the cyclone cone 22 can be arranged at the upper end opening of the dust collecting cylinder 21 to firmly fix the cyclone cone 22.

[0041] The lower end of the second filter screen 26 can be closed, so that the rotating airflow in the filtering channel 24 can move upward, so that the rotating airflow can flow to the lower opening of the machine body 11. The closed arrangement can further collect dirt in the filtering channel 24, which is convenient for the user to clean.

In this way, by filtering the gas to be cleaned by the first filter screen 25 and the second filter screen 26 respectively, the purification effect of the gas can be greatly improved.

[0044] In some embodiments, as shown in FIGS. 3 and 10, the cyclone cone 22 has a conical body, the first filter screen 25 is arranged on the sidewall of the conical body, and the outer wall of the conical body is provided with wind baffles 221, which form spiral air guide grooves 222 on the outer wall of the conical body.

[0045] The upper side of the conical body can be provided with spiral upward wind baffles 221, and the spiral air guide grooves 222 are formed between the plurality of wind baffles 221 and the sidewall of the dust collecting cylinder 21. When the rotating member 12 rotates to form an airflow in the first airflow channel 23, the spiral air guide grooves 222 can make the gas in the first airflow channel 23 rotate spirally, and the conical body of the cyclone cone 22 and the spiral upward wind baffles 221 can ensure that the spirally rotating gas flows from the lower end of the cyclone cone 22 to the upper end of the cyclone cone 22.

[0046] In the above embodiment, the spiral air guide grooves 222 formed by the wind baffles 221 on the outer wall of the conical body and the sidewall of the dust collecting cylinder 21 can make the gas entering the dust collecting cylinder 21 rotate spirally upward, so that the heavier dust particles and hairs in the gas can fall into the bottom of the dust collecting cylinder 21, and the cyclone airflow can be guided to flow to the lower opening of the machine body 11, effectively ensuring that the gas in the first airflow channel 23 can form a cyclone airflow, and simplifying the structure of the cyclone cone 22.

In FIG. 11, the arrow direction represents the flow direction of the gas.

[0048] In the above embodiment, when the gas to be cleaned can enter the hollow cavity of the conical body through the first filter screen 25 on the conical body, and the gas is filtered again by the second filter screen 26 arranged in the hollow cavity, the connection structure of the conical body and the second filter screen 26 can be simplified while ensuring the filtering effect, so as to improve the miniaturization and practicability of the filter screen assembly.

[0049] In some embodiments, as shown in FIG. 3, FIG. 4, FIG. 10 and FIG. 11, the secondary filter screen 26 is configured in a conical shape, and the small-diameter end of the secondary filter screen 26 is arranged at the bottom of the cyclone cylinder 22, and the large-diameter end of the secondary filter screen 26 is arranged at the lower opening of the machine body 11.

In this way, a stable cyclone gas can be formed in the first gas flow channel 23, and the side of the secondary filter screen 26 close to the lower opening of the machine body 11 has a larger air outlet area.

[0051] In the above embodiments, the secondary filter screen 26 is configured in a conical shape to guide the gas to flow to the side of the lower opening of the machine body 11. The open end of the large-diameter end of the secondary filter screen 26 is arranged towards the lower opening of the machine body 11, which can ensure that more filtered gas can be discharged per unit time, thereby ensuring the air exhaust efficiency of the filter screen assembly.

[0052] In some embodiments, as shown in FIG. 3 to FIG. 7, the main machine assembly 1 further comprises a driving member 13 for driving the rotating member 12 to rotate. The inside of the machine body 11 is formed with a second gas flow channel 111 which is in communication with the lower opening of the machine body 11. The second gas flow channel 111 is arranged around the driving member 13, and the upper opening of the machine body 11 is configured as the gas outlet of the second gas flow channel 111. In FIG. 6, the arrow direction represents the flow direction of the gas.

[0053] The output shaft of the driving member 13 can be connected with the rotating member 12 and apply a driving force to the rotating member 12 to drive the rotating member 12 to rotate circumferentially.

[0055] The main machine assembly 1 can further comprise an air guide ring which can be arranged at the joint between the rotating member 12 and the cyclone cylinder 22 to prevent the filtered gas from leaking through the joint, thereby ensuring the sealing of the gas purification device.

[0056] In the above embodiment, the driving member 13 can apply a force to the rotating member 12 to form a cyclone airflow in the first airflow channel 23. The second airflow channel 111 can deliver the filtered gas to the external gas to achieve the purpose of sufficient filtration and cleaning, and the arrangement of the second airflow channel 111 and the driving member 13 is compact, which is conducive to simplifying the structure size.

[0057] In some embodiments, as shown in FIGS. 3-7, the main assembly 1 further comprises a spoiler 14 arranged at the gas outlet of the second airflow channel 111 for increasing the pressure of the gas from the second airflow channel 111.

[0058] The spoiler 14 can have a plurality of spoiler ribs for correcting the airflow, which can change the direction of the airflow and increase the pressure of the airflow, so that the filtered gas can be quickly and evenly discharged.

[0059] The spoiler 14 can also change the way the gas flows, which helps to reduce the turbulence and resistance generated around the gas outlet, thereby reducing energy consumption.

[0060] In the above embodiment, by arranging the spoiler 14 at the gas outlet of the second airflow channel 111, the discharge pressure of the filtered gas can be increased, the efficiency of gas discharge can be improved, the energy consumption of the driving member 13 can be saved, and the gas dynamics performance of the main assembly 1 can be further improved.

[0061] In some embodiments, as shown in FIGS. 1-4, the air inlet 211 is arranged near the upper portion of the dust collecting cylinder 21.

[0062] In the above embodiment, the hair or dust particles with large mass in the gas to be cleaned can slide to the bottom of the dust collecting cylinder 21 under the action of centrifugal force and gravity. By arranging the air inlet 211 at the upper portion of the dust collecting cylinder 21, the dust particles can be prevented from falling out of the air inlet 211 during the sliding process while ensuring that the gas to be cleaned can be sucked in, effectively ensuring the practicability and rationality of the layout of the filtering assembly 2.

[0063] In some embodiments, as shown in FIGS. 3 and 4, the bottom of the dust collecting cylinder 21 is open, and the bottom of the dust collecting cylinder 21 is provided with a movable cylinder cover 212 and a first elastic member 213. The sidewall of the dust collecting cylinder 21 is provided with a cylinder cover switch 214 for unlocking or locking the movable cylinder cover 212 at the bottom of the dust collecting cylinder 21, and the first elastic member 213 is used to apply a force to the movable cylinder cover 212 to move away from the bottom of the dust collecting cylinder 21.

[0064] The movable cylinder cover 212 can be arranged at the bottom of the dust collecting cylinder 21 or connected to the bottom of the dust collecting cylinder 21 through a cylinder cover fixing frame. The hair or dust particles with large mass collected at the bottom of the dust collecting cylinder 21 can be taken out by opening the movable cylinder cover 212.

[0065] The bottom of the dust collecting cylinder 21 can further be provided with a first rotating shaft rotatably arranged at the bottom of the dust collecting cylinder 21. One end of the movable cylinder cover 212 can rotate around the first rotating shaft to realize opening or closing of the movable cylinder cover 212.

[0066] The first elastic member 213 can be sleeved outside the first rotating shaft. The movable cylinder cover 212 can always be kept in an open state under the action of the first elastic member 213 to facilitate the user to clean the dust particles in the dust collecting cylinder 21.

[0067] For example, the first elastic member 213 can be a torsion spring or other elastic structure. Any component that can store and release potential energy when twisted is within the scope of the present application, and the present application does not make any limitation thereon.

[0068] The cylinder cover switch 214 can have a locked state and an unlocked state. When the cylinder cover switch 214 is in the locked state, a recess is arranged at the side of the movable cylinder cover 212 away from the first elastic member 213. A protrusion is arranged at the corresponding position of the cylinder cover switch 214. Through the clamping action between the recess and the protrusion, the movable cylinder cover 212 can be firmly fixed to the bottom of the dust collecting cylinder 21. When the cylinder cover switch 214 is in the unlocked state, the above-mentioned recess and protrusion are separated. Under the action of the first elastic member 213, the movable cylinder cover 212 can move away from the bottom of the dust collecting cylinder 21.

[0069] In the above embodiment, the opening or closing of the movable cylinder cover 212 can be realized through the cylinder cover switch 214. Therefore, the user can clean the dust particles at the bottom of the dust collecting cylinder 21 in time through the movable cylinder cover, effectively improving the practicability and service life of the gas purification device.

[0070] In some embodiments, as shown in FIGS. 3 and 4, the cylinder cover switch 214 includes a trigger portion 215 pivotally connected to the side wall of the dust collecting cylinder 21. One end of the trigger portion 215 is clamped with the movable cylinder cover 212, and the other end acts on a second elastic member 216. The second elastic member 216 exerts force to clamp one end of the trigger portion 215 with the movable cylinder cover 212. When the second elastic member 216 is compressed under force, one end of the trigger portion 215 moves away from the movable cylinder cover 212 to unlock one end of the trigger portion 215 from the movable cylinder cover 212.

[0071] The protrusion of the above-mentioned cylinder cover switch 214 can be specifically arranged at one end of the trigger portion 215 to clamp the recess of the movable cylinder cover 212 through the protrusion.

[0072] The cylinder cover switch 214 can further comprise a second pivot shaft, and the middle position of the trigger part 215 is pivotally connected to the side wall of the dust collecting cylinder 21 through the second pivot shaft, so that when one end of the trigger part 215 moves towards the dust collecting cylinder 21, the other end of the trigger part 215 moves away from the dust collecting cylinder 21.

[0073] The second elastic member 216 can be arranged between the other end of the trigger part 215 and the side wall of the dust collecting cylinder, and when the user presses the other end of the trigger part 215, the other end of the trigger part 215 can move towards the dust collecting cylinder 21, at this time, the end of the trigger part 215 that is clamped with the movable cylinder cover 212 is raised in the opposite direction and is disengaged from the movable cylinder cover 212, so that the dirt such as dust and hair can be poured out from the bottom of the dust collecting cylinder 21.
