Description

Technical Field

[0001] The utility model relates to the technical field of gas purification, and particularly relates to a gas purification device. Background Art

[0002] An air purifier is the main equipment for purifying air. Currently, an air purifier usually uses a fan to deliver air containing dust to a filter screen, and adsorbs the dust in the filter screen to filter the air.

[0003] For example, a Chinese patent with the publication number CN104307264A discloses an air purifier. The air purifier includes an air purifier body and a power supply box. The air purifier body includes a motor, a filter screen, an air pump, an air inlet, an air outlet, and an air delivery pipeline. The power supply box is electrically connected to the motor. The motor is used to drive the air pump to suck air into the air delivery pipeline. The filter screen is placed inside the air delivery pipeline. The air outlet and the air inlet are respectively placed at both ends of the air delivery pipeline.

[0004] However, after long-term filtration by the existing air purifier, a large amount of dirt such as dust and hair stays in the filter screen and cannot be cleaned. Especially when there are pets at home, a large amount of pet hair is adsorbed in the filter screen. If not cleaned in time, it will not only affect the purification efficiency of the air purifier, but also easily breed bacteria, thus affecting the health of users. Summary of the Utility Model

[0005] In view of the above technical problems existing in the prior art, the utility model provides a gas purification device, which can preliminarily clean the air to be cleaned before entering the filter element assembly, so as to reduce the content of dirt in the air entering the filter element assembly, effectively reduce the cleaning cycle of the filter element assembly, improve the service life and cleaning efficiency of the filter element assembly, reduce the risk of bacteria breeding in the filter element assembly, and ensure the health of users.

[0006] The utility model provides a gas purification device. The gas purification device includes a main machine assembly and a filtering assembly. The main machine assembly includes a fuselage and a rotating member rotatably arranged inside the fuselage. The rotating member is arranged at the lower open end of the fuselage. The filtering assembly includes a dust collection cylinder and a cyclone cone cylinder arranged inside the dust collection cylinder. The dust collection cylinder is connected to the lower part of the fuselage. An air inlet is arranged on the side wall of the dust collection cylinder. A first air flow channel is formed between the dust collection cylinder and the cyclone cone cylinder. The cyclone cone cylinder has a filtering channel communicated with the lower open end of the fuselage. A filter element assembly for communicating the filtering channel and the first air flow channel is arranged on the cyclone cone cylinder. The cyclone cone cylinder is used to make the gas entering the first air flow channel through the air inlet form a cyclone air flow when the rotating member rotates, and the cyclone air flow flows to the lower open end of the fuselage through the filtering channel.

[0007] In some embodiments, the filter assembly includes a primary filter disposed on the side wall of the cyclone cone and a secondary filter disposed in the filter passage. The air outlet of the secondary filter communicates with the lower open end of the fuselage, so that the cyclone air flow is filtered through the primary filter and the secondary filter in sequence and then discharged to the lower open end of the fuselage. Thus, the cyclone air flow in the first air flow chamber can be filtered through the primary filter and the secondary filter in sequence and flow from the air outlet of the secondary filter to the lower open end of the fuselage, so as to achieve the purpose of multi-stage filtering and purifying the gas. Thus, by filtering the gas to be cleaned through the primary filter and the secondary filter respectively, the purification effect of the gas can be greatly improved.

[0008] In some embodiments, the cyclone cone has a conical body, the primary filter is disposed on the side wall of the conical body, and wind blocking ribs are provided on the outer wall of the conical body. The wind blocking ribs form a spiral air guiding groove on the outer wall of the conical body. Thus, the spiral air guiding groove formed by the wind blocking ribs on the outer wall of the conical body and the side wall of the dust collecting cylinder can make the gas entering the dust collecting cylinder rotate spirally upward. Thus, both the heavier dust particles and hairs in the gas can fall to the bottom of the dust collecting cylinder, and the cyclone air flow can be guided to flow towards the lower open end of the fuselage, effectively ensuring that the gas in the first air flow chamber can form a cyclone air flow and simplifying the structure of the cyclone cone.

[0009] In some embodiments, the conical body is configured as a hollow structure, and the hollow cavity of the conical body forms part of the filter passage, and the secondary filter is disposed in the hollow cavity. Thus, when the gas to be cleaned can enter the hollow cavity of the conical body through the primary filter on the conical body and is filtered again by the secondary filter disposed in the hollow cavity. Thus, while ensuring the filtering effect, the connection structure between the conical body and the secondary filter can be simplified to improve the miniaturization and practicality of the filter assembly.

[0010] In some embodiments, the secondary filter is configured as a conical shape, and the small-diameter end of the secondary filter abuts against the bottom of the cyclone cone, and the open end of the large-diameter end faces the lower open end of the fuselage. Thus, the conical shape of the secondary filter can guide the gas to flow towards the side of the lower open end of the fuselage. And the open end of the large-diameter end of the secondary filter faces the lower open end of the fuselage, which can ensure that more filtered gas can be discharged per unit time, thereby ensuring the exhaust efficiency of the filter assembly.

[0011] In some embodiments, the host component further includes a driving member for driving the rotating member to rotate. A second air flow channel communicating with the lower opening of the fuselage is formed inside the fuselage. The second air flow channel is arranged around the driving member, and the upper opening of the fuselage is configured as the air outlet of the second air flow channel. In this way, the driving member can apply a force to the rotating member to form a cyclone air flow in the first air flow channel. The second air flow channel can deliver the filtered gas into the external gas to achieve the purpose of sufficient filtration and cleaning. Moreover, the arrangement structure of the second air flow channel and the driving member is compact, which is beneficial to simplifying the structural size.

[0012] In some embodiments, the host component further includes a flow disturbing member, which is arranged at the air outlet of the second air flow channel and is used to increase the pressure of the gas from the second air flow channel. In this way, by arranging the flow disturbing member at the air outlet of the second air flow channel, the discharge pressure of the filtered gas can be increased, the gas discharge efficiency can be improved, the energy consumption of the driving member can be saved, and the gas dynamics performance of the host component can be further improved.

[0013] In some embodiments, the air inlet is arranged near the upper part of the dust collection cylinder. In this way, hairs or dust particles with larger mass in the gas to be cleaned can slide down to the bottom of the dust collection cylinder under the action of centrifugal force and gravity. By arranging the air inlet at the upper part of the dust collection cylinder, while ensuring the inhalation of the gas to be cleaned, the situation that dust particles fall out from the air inlet during the sliding process can be avoided, effectively ensuring the practicability and rationality of the layout of the filter component.

[0014] In some embodiments, the bottom of the dust collection cylinder is provided with an open mouth, and a movable cylinder cover and a first elastic member are arranged at the bottom of the dust collection cylinder. A cylinder cover switch is arranged on the side wall of the dust collection cylinder, and the cylinder cover switch is used to unlock or lock the movable cylinder cover at the bottom of the dust collection cylinder. The first elastic member is used to apply a force to the movable cylinder cover to make it away from the bottom of the dust collection cylinder. In this way, the movable cylinder cover can be opened or closed through the cylinder cover switch. Thus, the user can clean the dust particles at the bottom of the dust collection cylinder in time through the movable barrel cover, effectively improving the practicability and service life of the gas purification device.

[0015] In some embodiments, the cylinder cover switch includes a trigger portion pivotally connected to the side wall of the dust collection cylinder. One end of the trigger portion is engaged with the movable cylinder cover, and the other end acts on a second elastic member. The second elastic member applies a force to make one end of the trigger portion engage with the movable cylinder cover. When the second elastic member is compressed under force, one end of the trigger portion moves away from the movable cylinder cover, so that one end of the trigger portion is unlocked from the movable cylinder cover. In this way, by engaging or disengaging the trigger portion with the movable cylinder cover, the locking or unlocking of the movable cylinder cover can be realized, and the mechanical connection control method between the trigger portion and the movable cylinder cover can reduce the risk of failures generated when using circuit connection control, effectively improving the flexibility and reliability of the movable cylinder cover switch, as well as the convenience during cleaning of dirt.

[0016] Compared with the prior art, the beneficial effects of the embodiments of the present utility model are as follows: When the rotating member of the present utility model rotates, it can generate an air flow. The air inlet sucks in the gas to be cleaned. Through the structural design of the cyclone cone cylinder, a cyclone air flow can be formed in the first air flow channel. Larger-mass dust particles or hairs in the cyclone air flow collide with the inner wall of the dust collection cylinder under the action of centrifugal force, and after the collision, they fall to the bottom of the dust collection cylinder under the action of gravity, while the cyclone air flow containing fine particles can be filtered and purified by the filter assembly and then discharged. In this way, the gas to be cleaned can be preliminarily cleaned before entering the filter assembly, so as to reduce the content of dirt in the gas entering the filter assembly, effectively reducing the cleaning cycle of the filter assembly, improving the service life and cleaning efficiency of the filter assembly, reducing the risk of bacteria breeding in the filter assembly, and ensuring the health of users.

[0031] To enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific implementation manners.

[0032] The present utility model provides a gas purification device. As Figures 1 to 3As shown, the gas purification device includes a main body component 1 and a filtering component 2. The main body component 1 includes a body 11 and a rotating member 12 rotatably disposed within the body 11, and the rotating member 12 is disposed at the lower open end of the body 11. The filtering component 2 includes a dust collection cylinder 21 and a cyclone cone 22 disposed within the dust collection cylinder 21. The dust collection cylinder 21 is connected to the lower part of the body 11. An air inlet 211 is provided on the side wall of the dust collection cylinder 21, and a first air flow channel 23 is formed between the dust collection cylinder 21 and the cyclone cone 22. The cyclone cone 22 has a filtering channel 24 communicating with the lower open end of the body 11, and a filter screen assembly is provided on the cyclone cone 22 to communicate the filtering channel 24 and the first air flow channel 23. The cyclone cone 22 is configured to cause the gas entering the first air flow channel 23 through the air inlet 211 to form a cyclone air flow when the rotating member 12 rotates, and the cyclone air flow flows through the filtering channel 24 towards the lower open end of the body 11. Among them, Figure 2 and Figure 3 the arrow directions shown in

[0033] are the gas flow directions.

[0033] The main body component 1 and the filtering component 2 can be connected in a detachable manner. For example, threaded connection or snap connection, etc. This application does not make any limitation on this. As Figure 3 shown, when the main body component 1 and the filtering component 2 are in a connected state, the rotating member 12 within the body 11 and the cyclone cone 22 within the dust collection cylinder 21 can be arranged corresponding to each other in the vertical direction.

[0034] The main body component 1 may further include a control panel 3, and the control panel 3 can be disposed on the outer surface of the body 11. The user can control the opening or closing of the gas purification device by clicking the control panel 3, specifically, can control the rotation or stop of the rotating member 12.

[0035] The rotating member 12 can rotate circumferentially in the clockwise or counterclockwise direction. When the rotating member 12 rotates, an air flow is generated, and the air inlet 211 sucks in the gas to be cleaned. Through the structural design of the cyclone cone 22, a cyclone air flow can be formed within the first air flow channel 23. As Figure 8 and Figure 9 shown, the hair or dust particles with larger mass in the cyclone air flow can collide with the inner wall of the dust collection cylinder 21 under the action of centrifugal force, and slide down to the bottom of the dust collection cylinder 21 under the action of gravity after the collision. Thus, the gas to be cleaned can be preliminarily cleaned. Then, the preliminarily cleaned cyclone air flow can continue to enter the filter screen assembly and be discharged after being filtered and cleaned by the filter screen assembly. Among them, Figure 8 the arrow directions shown in

[0036] are the gas flow directions.

[0036] The inner wall of the dust collection cylinder 21 can be annular. An inclined plate can be provided at one end of the inner wall of the dust collection cylinder 21 away from the main machine assembly 1. The inclined plate can make the overall inner wall of the dust collection cylinder 21 conical. Dust particles falling along the inner wall of the dust collection cylinder 21 under the action of gravity can be concentrated and collected at the bottom of the dust collection cylinder 21 along the inclined plate, facilitating the user to clean.

[0037] In the above embodiment, when the rotating member 12 rotates, it can generate an air flow. The air inlet 211 inhales the gas to be cleaned. Through the structural design of the cyclone cone 22, a cyclone air flow can be formed in the first air flow channel 23. Larger-mass dust particles or hairs in the cyclone air flow collide with the inner wall of the dust collection cylinder 21 under the action of centrifugal force and fall to the bottom of the dust collection cylinder 21 after the collision under the action of gravity. The cyclone air flow containing fine particles can be filtered and purified by the filter element assembly and then discharged. In this way, the gas to be cleaned can be preliminarily cleaned before entering the filter element assembly, reducing the content of dirt in the gas entering the filter element assembly, effectively reducing the cleaning cycle of the filter element assembly, prolonging the service life and cleaning efficiency of the filter element assembly, reducing the risk of bacteria breeding in the filter element assembly, and ensuring the health of the user.

[0038] In some embodiments, as Figure 3 , Figure 4 , Figure 8 and Figure 9 shown, the filter element assembly includes a primary filter 25 provided on the side wall of the cyclone cone 22 and a secondary filter 26 provided in the filter channel 24. The air outlet of the secondary filter 26 is communicated with the lower open end of the fuselage 11, so that the cyclone air flow is filtered by the primary filter 25 and the secondary filter 26 in sequence and then discharged to the lower open end of the fuselage 11.

[0039] The primary filter 25 can be located outside the secondary filter 26, and a partial filter channel 24 is formed between the primary filter 25 and the secondary filter 26. The height of the secondary filter 26 can be less than the height of the cyclone cone 22, so that a gap is formed between the bottom of the secondary filter 26 and the bottom of the cyclone cone 22 for storing dust particles in the rotating air flow in the filter channel 24.

[0040] A supporting member adapted to the cyclone cone 22 can be provided at the upper opening of the dust collection cylinder 21 to firmly fix the cyclone cone 22.

[0041] The lower end of the secondary filter 26 can be closed. In this way, the rotating air flow in the filter channel 24 can be guided to move upward so that the rotating air flow can flow to the lower open end of the fuselage 11. And the closed setting can further collect the dirt in the filter channel 24, facilitating the user to clean.

[0042] An opening can be provided at the upper end of the filter screen assembly. In this way, the gas to be cleaned can be inhaled through the air inlet 211 on the side wall of the dust collection cylinder 21, and after being filtered by the primary filter screen 25 and the secondary filter screen 26, it is discharged through the opening at the upper end of the filter screen assembly.

[0043] In the above embodiment, the cyclone airflow in the first airflow channel 23 can flow through the primary filter screen 25 and the secondary filter screen 26 in sequence, and then flow from the air outlet of the secondary filter screen 26 to the lower open end of the fuselage 11 to achieve the purpose of multi-stage filtering and purifying the gas. In this way, by filtering the gas to be cleaned through the primary filter screen 25 and the secondary filter screen 26 respectively, the purification effect of the gas can be greatly improved.

[0044] In some embodiments, such as Figure 3 and Figure 10 shown, the cyclone cone 22 has a conical body, the primary filter screen 25 is arranged on the side wall of the conical body, and wind blocking ribs 221 are provided on the outer wall of the conical body. The wind blocking ribs 221 form a spiral air guiding groove 222 on the outer wall of the conical body.

[0045] The upper side of the conical body can be provided with wind blocking ribs 221 spiraling upward. A spiral air guiding groove 222 is formed between the plurality of wind blocking ribs 221 and the side wall of the dust collection cylinder 21. When the rotating member 12 rotates to form an airflow in the first airflow channel 23, the spiral air guiding groove 222 can make the gas in the first airflow channel 23 rotate spirally, and the conical body of the cyclone cone 22 and the wind blocking ribs 221 spiraling upward 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 guiding groove 222 formed by the wind blocking ribs 221 on the outer wall of the conical body and the side wall of the dust collection cylinder 21 can make the gas entering the dust collection cylinder 21 rotate spirally upward. In this way, the heavier dust particles and hairs in the gas can fall to the bottom of the dust collection cylinder 21, and at the same time, the cyclone airflow can be guided to flow towards the lower open end of the fuselage 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.

[0047] In some embodiments, such as Figure 3 、 Figure 4 、 Figure 10 and Figure 11 shown, the conical body is constructed as a hollow structure, and the hollow cavity of the conical body forms a partial filter channel 24, and the secondary filter screen 26 is arranged in the hollow cavity. Among them, Figure 11 The arrow direction shown in indicates the gas flow direction.

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

[0049] In some embodiments, such as Figure 3 , Figure 4 , Figure 10 and Figure 11 shown, the secondary filter screen 26 is configured as a conical shape, and the small-diameter end of the secondary filter screen 26 abuts against the bottom of the cyclone cone 22, and the open end of the large-diameter end is arranged towards the lower opening of the fuselage 11.

[0050] The shape of the secondary filter screen 26 can be adapted to the shape of the conical body. When the conical body is sleeved outside the secondary filter screen 26, the small-diameter end of the secondary filter screen 26 is arranged on the side close to the bottom of the dust collection cylinder 21, and the large-diameter end of the secondary filter screen 26 is arranged on the side close to the lower opening of the fuselage 11. In this way, a stable cyclone gas can be formed in the first air flow channel 23, and the side of the secondary filter screen 26 facing the lower opening of the fuselage 11 has a relatively large air outlet area.

[0051] In the above embodiments, the secondary filter screen 26 being configured as a conical shape can guide the gas to flow towards the lower opening of the fuselage 11. And the open end of the large-diameter end of the secondary filter screen 26 facing the lower opening of the fuselage 11 can ensure that more filtered gas can be discharged per unit time, thereby ensuring the exhaust efficiency of the filter screen assembly.

[0052] In some embodiments, such as Figures 3 to 7 shown, the main machine assembly 1 further includes a driving member 13 for driving the rotating member 12 to rotate. A second air flow channel 111 communicating with the lower opening of the fuselage 11 is formed inside the fuselage 11, and the second air flow channel 111 is arranged around the driving member 13. The upper opening of the fuselage 11 is configured as the air outlet of the second air flow channel 111. Among them, Figure 6 the arrow direction shown in

[0053] is the gas flow direction. The output shaft of the driving member 13 can be connected to the rotating member 12 and apply a driving force to the rotating member 12 to drive the rotating member 12 to rotate circumferentially. Exemplarily, the driving member 13 can be a device such as a motor, and the rotating member 12 can be configured as a wind wheel.

[0054] An annular cavity may be provided inside the fuselage 11, and the driving member 13 is disposed in the annular cavity. A second air flow channel 111 is formed between the outer wall of the annular cavity and the inner side wall of the fuselage 11. The second air flow channel 111 may be configured as an annular air duct surrounding the driving member 13. One end of the second air flow channel 111 may be connected to the air outlet of the secondary filter 26, and the other end of the second air flow channel 111 may be directly connected to the external gas. The filtered gas may be discharged into the external gas from the other end of the second air flow channel 111, that is, the upper open end of the fuselage 11.

[0055] The main machine assembly 1 may further include a wind guide ring, and the wind guide ring may be disposed at the joint where the rotating member 12 is connected to the cyclone cone 22 to prevent the filtered gas from leaking through the joint, ensuring the sealing performance of the gas purification device.

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

[0057] In some embodiments, as Figures 3 to 7 shown, the main machine assembly 1 further includes a spoiler 14, and the spoiler 14 is disposed at the air outlet of the second air flow channel 111 for increasing the pressure of the gas from the second air flow channel 111.

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

[0059] The spoiler 14 may also change the gas flow mode, which helps to reduce the turbulence and resistance generated around the air outlet, thereby reducing the energy consumption.

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

[0061] In some embodiments, as Figures 1 to 4 shown, the air inlet 211 is disposed near the upper part of the dust collection cylinder 21.

[0062] In the above embodiments, hairs or dust particles with relatively large mass in the gas to be cleaned can slide down to the bottom of the dust collection cylinder 21 under the action of centrifugal force and gravity. By arranging the air inlet 211 at the upper part of the dust collection cylinder 21, while ensuring the inhalation of the gas to be cleaned, the situation where dust particles fall out from the air inlet 211 during the sliding process can be avoided, effectively ensuring the practicality and rationality of the layout of the filter assembly 2.

[0063] In some embodiments, as Figure 3 and Figure 4 shown, the bottom of the dust collection cylinder 21 is provided with an open end, and a movable cylinder cover 212 and a first elastic member 213 are provided at the bottom of the dust collection cylinder 21. A cylinder cover switch 214 is provided on the side wall of the dust collection cylinder 21. The cylinder cover switch 214 is used to unlock or lock the movable cylinder cover 212 at the bottom of the dust collection cylinder 21, and the first elastic member 213 is used to apply a force to the movable cylinder cover 212 to make it away from the bottom of the dust collection cylinder 21.

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

[0065] A first rotating shaft can also be provided at the bottom of the dust collection cylinder 21. The first rotating shaft is rotatably assembled at the bottom of the dust collection cylinder 21. One end of the movable cylinder cover 212 can rotate around the first rotating shaft to open or close the movable cylinder cover 212.

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

[0067] Exemplarily, the first elastic member 213 can be a torsion spring or other elastic structures. Any component that can store and release potential energy during torsion is within the scope of this application, and this application does not make any limitation thereto.

[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 groove is provided on the side of the movable cylinder cover 212 away from the first elastic member 213, and a convex block is provided at the corresponding position of the cylinder cover switch 214. Through the clamping action between the groove and the convex block, the movable cylinder cover 212 can be firmly fixed at the bottom of the dust collection cylinder 21. When the cylinder cover switch 214 is in the unlocked state, the above groove and the convex block are disengaged, and under the action of the first elastic member 213, the movable cylinder cover 212 can move in a direction away from the bottom of the dust collection cylinder 21.

[0069] In the above embodiment, the movable barrel cover 212 can be opened or closed by the barrel cover switch 214, so that the user can clean the dust particles at the bottom of the dust barrel 21 in time through the movable barrel cover, which effectively improves the practicality and service life of the gas purification device.

[0070] In some embodiments, Figure 3 and Figure 4 As shown, the barrel cover switch 214 includes a trigger portion 215 pivotally connected to the side wall of the dust collecting barrel 21, one end of the trigger portion 215 is clamped with the movable barrel cover 212, and the other end acts on the second elastic member 216. The second elastic member 216 applies force to make one end of the trigger portion 215 clamped with the movable barrel cover 212. When the second elastic member 216 is compressed, one end of the trigger portion 215 moves in a direction away from the movable barrel cover 212, so that one end of the trigger portion 215 is unlocked from the movable barrel cover 212.

[0071] The protrusion of the tube cover switch 214 can be specifically arranged at one end of the trigger portion 215 so as to be engaged with the groove of the movable tube cover 212 via the protrusion.
