Description

Technical Field

[0001] The present application relates to the technical field of plasma generators, and in particular to a dust-proof filtering device for a plasma generator. Background Art

[0002] A plasma generator is a device that can convert gas into plasma. It produces a large number of positive and negative ions by ionizing the gas. Plasma is an ionized gas composed of free electrons and ions. It is highly reactive and therefore has a wide range of applications in many fields. The working principle of a plasma generator is to ionize the air using positive and negative high voltages, mainly producing the ionization of oxygen.

[0003] The prior art also proposes an improvement plan for the plasma generator. For example, a patent application with publication number CN215062692U discloses a plasma generator for sterilization and air purification in a limited space, including a plasma generator body and a ventilation device; the plasma generator body is installed in the ventilation system of the ventilation device; an air filter mechanism is installed in the outer gap of the plasma generator body for dust protection of the plasma generator body. A plasma generator is installed at the air inlet of the ventilation device. The plasma generator generates plasma after the pulse power supply is turned on to sterilize the air entering the ventilation device. Since an air filter mechanism is installed on the front side of the plasma generator, it can effectively prevent dust and protect the plasma generator, thereby extending the service life of the plasma generator.

[0004] Although the above technical solution can filter the air, there are still other problems in actual use. For example, when the air filter mechanism is used for a long time, too many fine particles will adhere to the filter screen, which will not only affect the normal filtration of the filter mechanism, but also affect the air entering the plasma generator.

[0005] Therefore, it is necessary to provide a plasma generator dust-proof filtering device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0015] Furthermore, a rotating column adapted to the gear is provided inside the plasma generator body, and a slide groove adapted to baffle one and baffle two is provided inside the plasma generator body. The slide groove can facilitate the mutual combination of baffle one and baffle two, thereby facilitating the blocking of the air inlet by both and ensuring the processing of fine particles.

[0034] When working, the plasma generator is a device that can convert gas into plasma. It generates a large number of positive ions and negative ions by ionizing gas. When the outside air enters the generating chamber 2 from the air inlet 3, the fine particles and impurities in the air will be blocked by the dust bag 4 on the surface of the air inlet 3, and the cleaner air will enter the generating chamber 2 through the dust bag 4 and process the air; some fine particles and impurities with low adhesion will fall along the surface of the dust bag 4 to the inside of the recovery tray 5 below, while fine particles and impurities with high adhesion will adhere to the surface of the dust bag 4. After a period of use, the adhesive fine particles and impurities on the surface of the dust bag 4 can be cleaned into the recovery tray 5 through the action of the cleaning mechanism, which can ensure the repeated use of the dust bag 4, facilitate the normal use of the plasma generator body 1 in the embodiment of the present invention, and improve the air treatment effect.

[0036] Reference Figures 2 to 8 As shown, a rotating shaft 601 is rotatably mounted inside each assembly groove 6, and the outer circumferences of the two rotating shafts 601 are connected by a belt, and the end of one of the rotating shafts 601 is connected to the output end of the motor, and the outer circumferences of the two rotating shafts 601 are fixedly mounted with winding rollers 7, and the outer circumferences of the two winding rollers 7 are fixedly mounted with clamping columns 8, and the upper and lower sides of the dust bag 4 are respectively clamped on the outer surfaces of the two clamping columns 8, and the surface of the dust bag 4 is provided with a clamping groove adapted to the clamping column 8;

[0037] During operation, when the dust bag 4 is in normal use, its upper and lower ends are respectively clamped on the outer surface of the clamping column 8, and then the motor drives the rotating shaft 601 to rotate, so that the rotating shaft 601 drives the winding roller 7 to rotate, so that the two winding rollers 7 tighten and straighten the dust bag 4 on its outer circumference. In this way, when the airflow mixed with foreign matter continuously impacts the surface of the dust bag 4, the dust bag 4 in the straightened state can form an effective support for the outer dustproof layer, maintain the shape and physical structure of the dust bag 4, and then maintain its long-term and stable dustproof effect.

[0038] The cleaning mechanism comprises a cleaning plate 9 slidably mounted inside the generating chamber 2, a cleaning brush is sleeved on the surface of the cleaning plate 9 close to the dust bag 4, an L-shaped support rod 10 is fixedly mounted on the side wall of the cleaning plate 9, and an oil cylinder 11 is fixedly mounted on the side wall of the plasma generator body 1, and the telescopic end of the oil cylinder 11 is connected to the end of the L-shaped support rod 10;

[0040] A baffle 12 is fixedly installed on the side wall of the L-shaped support rod 10, and the baffle 12 is located at the lower side of the cleaning plate 9. During operation, when the L-shaped support rod 10 moves down along the dust bag 4, the L-shaped support rod 10 will simultaneously drive the baffle 12 to move, and the baffle 12 will block one side of the cleaning plate 9. This can reduce the problem of the cleaning plate 9 floating to the outside of the air inlet 3 due to the light weight of the particles when processing the adhered particles, thereby facilitating all the adhered particles to fall into the recovery tray 5.

[0041] The cleaning mechanism also includes a fixed frame 13 fixedly mounted on the lower side of the side wall of the plasma generator body 1, a baffle 2 14 is slidably mounted inside the fixed frame 13, the baffle 1 12 and the baffle 2 14 are arranged on the same vertical plane, and a linkage unit is arranged inside the plasma generator body 1, and the linkage unit is used to drive the baffle 2 14 to move toward the side close to the baffle 1 12;

[0042] During operation, when the L-shaped support rod 10 drives the baffle 12 to move downward, the L-shaped support rod 10 will simultaneously drive the baffle 2 14 to move upward through the linkage unit, that is, when the baffle 12 moves downward, the baffle 2 14 will simultaneously move upward and contact each other, that is, the outer side of the cleaning plate 9 can be shielded, so as to prevent the fine particles on the surface of the cleaning plate 9 from falling to the outside of the plasma generator body 1 when the dust bag 4 is cleaned, so as to facilitate the centralized treatment of the surface damage of the dust bag 4.

[0043] Reference Figures 4 to 8 As shown, the linkage unit includes a gear 15 rotatably mounted inside the plasma generator body 1, two gears 15 are provided, and are symmetrically arranged relative to the dust bag 4, a ratchet plate 16 is fixedly installed on the side wall of the baffle plate 14, a connecting frame 17 is fixedly installed on the side wall of the L-shaped support rod 10, and a ratchet plate 2 18 is installed on the side of the connecting frame 17 away from the ratchet plate 16, and the ratchet plate 16 and the ratchet plate 2 18 are meshed and connected with the gear 15; when working, when the L-shaped support rod 10 is lowered, When the air inlet 3 is moved upward, the L-shaped support rod 10 will simultaneously drive the connecting frame 17 and the ratchet plate 2 18 to move downward, the ratchet plate 2 18 will drive the ratchet plate 1 16 to move upward through the transmission of the gear 15, and the ratchet plate 1 16 will drive the baffle plate 2 14 to move upward, that is, when the baffle plate 12 moves downward, the baffle plate 2 14 will move upward synchronously, so as to ensure that the dust bag 4 is cleaned, the air inlet 3 is blocked, and the problem of the cleaned fine particles being blown to the outside of the plasma generator body 1 due to the effect of wind is avoided, and it is safer and more convenient to use.

[0044] A through groove 19 is provided on the surface of the baffle plate 2 14 , and the shape of the through groove 19 is matched with the shape of the baffle plate 12 , and the through groove 19 and the baffle plate 12 are located on the same vertical plane; during operation, when the baffle plate 12 and the baffle plate 2 14 move relative to each other, since the through groove 19 is provided on the surface of the baffle plate 2 14 , the baffle plate 12 can be conveniently extended into the through groove 19 , thereby facilitating the cleaning plate 9 to completely clean the dust bag 4 .

[0045] The plasma generator body 1 is provided with a rotating column matched with the gear 15, and the plasma generator body 1 is provided with a slide groove matched with the baffle 12 and the baffle 2 14. The slide groove is provided to facilitate the mutual combination of the baffle 12 and the baffle 2 14, thereby facilitating the blocking of the air inlet 3 by both, thereby ensuring the processing of fine particles.

[0046] Two cleaning plates 9 are provided, and their side walls are connected by a connecting bracket. The cleaning brushes on the surfaces of the two cleaning plates 9 are in contact with the two surfaces of the dust bag 4 respectively. Such a design can facilitate the cleaning plates 9 to clean the two surfaces of the dust bag 4. When the dust bag 4 needs to be replaced, it can be replaced by simply taking the dust bag 4 out from the surface of the clamping column 8.

[0047] Working principle: A plasma generator is a device that can convert gas into plasma. It generates a large number of positive ions and negative ions by ionizing gas. When external air enters the generating chamber 2 from the air inlet 3, the fine particles and impurities in the air will be blocked by the dust bag 4 on the surface of the air inlet 3, and the relatively clean air will enter the generating chamber 2 through the dust bag 4 and process the air; some fine particles and impurities with low adhesion will fall along the surface of the dust bag 4 to the inside of the recovery tray 5 below, while fine particles and impurities with high adhesion will adhere to the surface of the dust bag 4. After a period of use, the adhesive fine particles and impurities on the surface of the dust bag 4 can be cleaned into the recovery tray 5 through the action of the cleaning mechanism, thereby ensuring the multiple uses of the dust bag 4, facilitating the normal use of the plasma generator body 1 in the embodiment of the present invention, and improving the air treatment effect;

[0048] When the dust bag 4 is in normal use, its upper and lower ends are respectively clamped on the outer surface of the clamping column 8, and then the motor drives the rotating shaft 601 to rotate, so that the rotating shaft 601 drives the winding roller 7 to rotate, so that the two winding rollers 7 tighten and straighten the dust bag 4 on its outer peripheral surface. In this way, when the airflow is mixed with foreign matter and continuously impacts the surface of the dust bag 4, the dust bag 4 in the straightened state can form an effective support for the external dustproof layer, maintain the shape and physical structure of the dust bag 4, and then maintain its long-term and stable dustproof effect; in the initial state, the cleaning plate 9 is located at the uppermost side of the dust bag 4, and the cleaning plate 9 does not affect the normal use of the dust bag 4; when the dust bag 4 has too many fine particles adhered to its surface under long-term filtering, at this time, the telescopic end of the oil cylinder 11 is controlled to move, so that the telescopic end drives the L-shaped support rod 10 and the cleaning plate 9 to move, and the cleaning plate 9 will slowly clean along the surface of the dust bag 4 from top to bottom, and clean the fine particles adhered to the surface of the dust bag 4 to the inside of the recovery tray 5, so as to facilitate the subsequent normal filtering effect of the dust bag 4 on the air;

[0049] When the L-shaped support rod 10 moves down along the dust bag 4, the L-shaped support rod 10 will simultaneously drive the baffle plate 12 to move, and the baffle plate 12 will cover one side of the cleaning plate 9, so that when the cleaning plate 9 processes the adhered particles, the problem of the particles floating to the outside of the air inlet 3 due to their light weight can be reduced, so that all the adhered particles can fall into the recovery plate 5; when the L-shaped support rod 10 moves down, the L-shaped support rod 10 will simultaneously drive the connecting frame 17 and the ratchet plate 2 18 to move down, and the ratchet plate 2 18 will drive the ratchet plate 1 16 to move up through the transmission of the gear 15 , the ratchet plate 16 drives the baffle plate 2 14 to move upward, that is, when the baffle plate 12 moves downward, the baffle plate 2 14 will move upward synchronously, so that the air inlet 3 is blocked when the dust bag 4 is cleaned, avoiding the problem that the cleaned fine particles are blown to the outside of the plasma generator body 1 due to the action of wind, and the use is safer and more convenient; when the baffle plate 12 and the baffle plate 2 14 move relative to each other, since the through groove 19 is provided on the surface of the baffle plate 2 14, the baffle plate 12 can be conveniently extended into the through groove 19, so that the cleaning plate 9 can completely clean the dust bag 4.
