Description

Technical Field

[0001] This utility model relates to the field of plasma generation technology, specifically a plasma generation device. Background Technology

[0002] Plasma generators are devices that use a boost circuit to raise low voltage to positive and negative high voltage. These high voltages ionize the air to produce a large number of positive and negative ions, with the number of negative ions being greater than the number of positive ions. Furthermore, the instantaneous neutralization of positive and negative charges between the positive and negative ions in the air releases a huge amount of energy, which can effectively achieve sterilization. They are widely used, especially in the field of air purification.

[0003] As disclosed in announcement number CN215971047U, a plasma generating device includes: a shell, an insulator, a needle electrode, a negative electrode, and a wire. The shell has multiple channels around its circumference, and the extension lines of the channels intersect at the center of the shell. Adjacent channels are staggered along the longitudinal direction of the shell. The insulator is fixed in each channel, the needle electrode is fixed in the insulator, and the end of the needle electrode with the needle tip extends out of the insulator and approaches the center of the shell. The negative electrode is fixed in the center of the shell, and there is a gap between the negative electrode and the needle electrode. The wire connects multiple needle electrodes in series. The plasma generating device provided by this utility model is applied to a vehicle air purifier, which can effectively circulate, filter, disinfect, and sterilize the air inside the vehicle, thereby improving the air quality inside the vehicle, solving the problem of cross-infection of germs, and ensuring the safety of passengers.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Please see Figures 1-7 .

[0045] To address the problems in existing technologies where dust from the air easily enters the device, making it inconvenient to filter incoming and outgoing gases, and where the plasma generator generates a lot of heat during air ionization, resulting in poor heat dissipation and affecting its service life, this solution provides the following technical solution: a plasma generator comprising a device housing 1, a positive electrode plate 2, a negative electrode plate 3, and a voltage regulator 4. Dust filters 7 are respectively attached to the left and right ends of the device housing 1, and a limiting mechanism is provided at the upper end of the dust filters 7. This limiting mechanism drives the dust filters 7 to form a disassembly structure on the outside of the device housing 1. A fan 18 is installed on the inside of the device housing 1, and a heat dissipation copper fin 20 is embedded in the inner rear end of the device housing 1. Simultaneously, a heat dissipation fin 21 is provided at the rear end of the heat dissipation copper fin 20, and the heat dissipation fin 21 extends outward from the outer rear end of the device housing 1.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a mounting base 5 is provided at the upper end of the device housing 1. The device is connected to external objects through the mounting base 5 and bolts. A positive electrode plate 2, a negative electrode plate 3, and a voltage regulator 4 are installed in the device housing 1. Gas slots 6 are provided at both ends of the device housing 1. The gas slot 6 on the left is the outlet and the gas slot 6 on the right is the inlet. The device is connected to an external power source. The voltage regulator 4 can improve the stability of the voltage. The gas entering the device housing 1 is ionized by the negative electrode plate 3 and the voltage regulator 4. After ionization, positive and negative ions are generated. The positive and negative ions neutralize in the air and release huge energy in an instant, which changes the structure of the surrounding bacteria or converts the energy, thus achieving sterilization. This process is a mature existing technology and will not be described in detail. Combined with the dust filter 7, the gas entering the device housing 1 can be filtered and dust removed to prevent dust from entering the device housing 1.

[0047] When too much dust adheres to the dust filter 7, the fixed cap 16, which is connected to the outer surface of the fixed rod 15 by a rotating thread, moves upward and out of the fixed groove 17, thereby releasing the lock between the movable connecting plate 14 and the fixed connecting block 12. Then, the movable connecting rod 13 is pulled outward, and the movable connecting rod 13 slides between the fixed connecting block 12. The movable connecting rod 13 drives the positioning plate 10 to move in the fixed connecting block 12, and the movable connecting plate 14 is disengaged from the fixed rod 15. At this time, the positioning plate 10 drives the positioning protrusion 11 to disengage from the auxiliary positioning plate 9, thereby releasing the clamping limit on the auxiliary positioning plate 9, and thus releasing the limit on the dust filter 7. Then, the dust filter 7 is pulled upward, and the lower end of the dust filter 7 is moved out of the fixed connecting plate 8, which facilitates the disassembly, cleaning or replacement of the dust filter 7 and prevents the dust filter 7 from being blocked by dust during long-term use.

[0048] In addition, a fan 18 and a perforated partition 19 are provided in the outer casing 1 of the device. The fan 18 accelerates the air flow in the outer casing 1 of the device and dissipates the heat in the outer casing 1 of the device. Furthermore, a heat dissipation copper fin 20 is embedded in the rear end of the outer casing 1. The heat dissipation copper fin 20 drives the heat dissipation fins 21 to extend out of the outer side of the rear end of the outer casing 1. The heat dissipation copper fin 20 and the heat dissipation fins 21 assist in the heat dissipation of the outer casing 1 of the device, further improve the heat dissipation effect, prevent heat accumulation, and thus extend the overall service life.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
