Description
Technical Field
[0001] The utility model relates to the technical field of plasma, in particular to a low-temperature plasma jet array generating electrode. Background Art
[0002] Low-temperature plasma has a very broad application prospect and has been widely used in sterilization, disinfection, surface treatment and other aspects.
[0003] When the existing low-temperature plasma jet array generating electrode is in use, the bottom of the reaction chamber is fixed, and only an overflow hole is opened at the bottom of the reaction chamber. Overflow is performed through the overflow hole to discharge the plasma. When the plasma is formed, the gas pressure is too high and the reaction gas in the unit increases, so the gas pressure in the reaction chamber will increase. However, the overflow hole is small and the pressure relief effect is limited. If the gas pressure increases too quickly and too high, the reaction chamber itself will explode. The existing low-temperature plasma jet array generating electrode does not have an explosion-proof effect when in use. For this reason, the present application proposes a low-temperature plasma jet array generating electrode. Utility Model Content

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0031] The utility model provides a low-temperature plasma jet array generating electrode. When the gas pressure inside the reaction chamber increases sharply, the gas pressure impacts the overflow cover, causing the overflow cover to slide out of the reaction chamber. At this time, a gap is generated between the overflow cover and the reaction chamber, and the gas can be discharged from the gap to release the pressure, thereby avoiding the situation where the overflow hole is too small to release the pressure in time and cause an explosion, thereby achieving an explosion-proof effect. After the pressure stabilizes, the overflow cover is reset under the action of the spring to perform normal overflow. Please refer to Figure 1-Figure 7 , including: a reaction mechanism 100 and an overflow cover 200.
[0032] The reaction mechanism 100 includes a reaction chamber 110, an electrode rod 120, an air inlet box 130, an air inlet pipe 140 and a support ring 150. The electrode rod 120 is arranged on the top of the reaction chamber 110, the top of the side wall of the reaction chamber 110 is connected to the air inlet box 130, the outside of the air inlet box 130 is connected to the air inlet pipe 140, and the support ring 150 is arranged inside the bottom opening of the reaction chamber 110;
[0033] The reaction chamber 110 is a round tube with a closed top and an open bottom. Figure 1 Figure 2 and Figure 3 The electrode rod 120 shown in the figure is one, and the actual number of electrode rods 120 used can be adjusted according to needs. The figure only shows the electrode rods 120 located at the top of the reaction chamber 110, and the number is not limited;
[0034] The reaction gas is introduced from the gas inlet pipe 140 and enters the reaction chamber 110 after passing through the gas inlet box 130. The electrode rod 120 is connected to an external power source and energized to make the reaction gas react to generate plasma.
[0035] The overflow cover 200 is disposed at the bottom opening of the reaction chamber 110. The overflow cover 200 includes a round cover 210, an overflow hole 220 and a spring 230. The round cover 210 is slidably connected to the bottom of the inner cavity of the reaction chamber 110. The overflow hole 220 is opened at the center of the round cover 210. The spring 230 is connected between the top of the round cover 210 and the support ring 150.
[0036] Among them, when the spring 230 is in a natural state, the round cover 210 is located inside the reaction chamber 110, the upper end of the spring 230 is fixed on the support ring 150, and the lower end of the spring 230 is fixed on the round cover 210. Under stable pressure, the plasma is evenly discharged through the overflow hole 220 array. When the air pressure inside the reaction chamber 110 increases sharply, the air pressure squeezes the round cover 210, causing the round cover 210 to move downward and move out from the bottom opening of the reaction chamber 110. At this time, a gap is generated between the round cover 210 and the reaction chamber 110, and the pressure is quickly discharged and released through the gap between the round cover 210 and the reaction chamber 110.
[0037] When the gas pressure in the reaction chamber 110 increases sharply, the gas in the reaction chamber 110 will surge back toward the air inlet pipe 140. To avoid damage to the gas supply equipment caused by the gas surge, a movable chamber 160 is provided at the bottom of the air inlet box 130. A movable part 300 is provided inside the movable chamber 160. The movable part 300 includes a movable block 310, a round slope 320 and an air groove 330. The movable block 310 is slidably connected in the movable chamber 160. A round slope 320 is provided at one end of the top of the movable block 310 close to the air inlet pipe 140. An air groove 330 is provided on one side of the movable block 310 close to the reaction chamber 110.
[0038] When the airflow enters the reaction chamber 110 normally from the air inlet pipe 140 to the right, the airflow flows to the reaction chamber 110 along the round slope 320. At this time, the movable part 300 is received into the movable chamber 160 by the pressure of the airflow, which does not affect the normal delivery of the airflow. When the air pressure in the reaction chamber 110 increases sharply, the airflow surges back. At this time, the airflow flows from the right to the left. The upper airflow flows to the air inlet pipe 140 through the gap between the movable part 300 and the air inlet box 130, and the lower airflow enters the movable chamber 160 through the air groove 330 (such as Figure 7 As shown in the figure, since the volume of the active chamber 160 is much smaller than that of the air inlet box 130, the air pressure in the active chamber 160 increases faster than that in the air inlet box 130, so that the air pressure inside the active chamber 160 causes the movable part 300 to rise, and the rising movable part 300 seals the air inlet box 130.
[0039] Since it is impossible to directly observe the state of the rapid increase in air pressure in the reaction chamber 110, an observation component 400 is connected to the top of the reaction chamber 110. The observation component 400 includes an air pipe 410 and a balloon 420. The air pipe 410 is connected to the top of the reaction chamber 110, and the outer end of the air pipe 410 is connected to the balloon 420. When the air pressure increases rapidly, the air pressure will be filled into the balloon 420 to expand the balloon 420.
[0040] Since the round cover 210 needs to rebound, in order to ensure that the round cover 210 rebounds stably back to the inside of the reaction chamber 110, sliding holes 170 are provided at both ends of the support ring 150, and sliding rods 240 inserted into the sliding holes 170 are provided on both sides of the round cover 210. The sliding rods 240 slide linearly on the sliding holes 170 to provide guidance, so that the round cover 210 can move stably and rebound stably back to the inside of the reaction chamber 110.
[0041] When the round cover 210 slides down too much, the slide bar 240 will fall off from the slide hole 170 . Therefore, an anti-fall-off block 250 is provided at the top of the slide bar 240 to limit the slide bar 240 and prevent the slide bar 240 from falling off from the slide hole 170 .
[0042] Since it is necessary to realize uniform generation of plasma in an array, the overflow holes 220 are evenly distributed in the center of the circular cover 210 so that the plasma can be discharged evenly.
[0043] In specific use, the reaction gas is introduced from the air inlet pipe 140, passes through the air inlet box 130 and enters the reaction chamber 110, the electrode rod 120 is connected to the external power supply and energized, so that the reaction gas reacts to generate plasma, and the plasma is uniformly discharged through the overflow hole 220 array;
[0044] When plasma is formed, the gas pressure is too high, and the reaction gas in the unit increases, so that the pressure inside the reaction chamber 110 increases. When the gas pressure inside the reaction chamber 110 increases sharply, the gas pressure squeezes the round cover 210, so that the round cover 210 moves down and moves out from the bottom opening of the reaction chamber 110. At this time, a gap is generated between the round cover 210 and the reaction chamber 110, and the pressure is quickly discharged through the gap between the round cover 210 and the reaction chamber 110, which has an explosion-proof effect. After the pressure stabilizes, the spring 230 drives the round cover 210 to rebound and reset, and continues to overflow stably; at the same time, the gas pressure will be filled into the balloon 420 to expand the balloon 420, so that the reaction chamber 110 can be directly observed from the outside. The air pressure increases sharply. At the same time, the inflated balloon 420 can relieve the pressure. In addition, when the air pressure in the reaction chamber 110 increases sharply, the airflow surges back. At this time, the airflow flows from the right to the left. The upper airflow flows to the air inlet pipe 140 through the gap between the movable part 300 and the air inlet box 130, and the lower airflow enters the movable chamber 160 through the air groove 330. Since the volume of the movable chamber 160 is much smaller than that of the air inlet box 130, the air pressure in the movable chamber 160 increases faster than that of the air inlet box 130, so that the internal air pressure of the movable chamber 160 prompts the movable part 300 to rise, and the rising movable part 300 seals the air inlet box 130, thereby reducing the harm caused by the airflow surge.
[0045] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
