Description

Technical Field

[0001] The present invention relates to the technical field of power supplies, in particular to a plasma deodorizing power supply. Background Art

[0002] A plasma power supply is an energy conversion device that converts input electrical energy into plasma, which is then supplied to a plasma generator, other equipment, or system. Plasma is generated by exciting gas molecules with a high-frequency signal, and is characterized by stability, controllability, and high efficiency.

[0003] Plasma power supplies also have excellent performance in the field of air purification. However, due to the high voltage operation during the operation of plasma power supplies, and in order to protect the power supply from interference such as dust, the power supply is usually sealed and then cooled by a fan. However, since the space where the power supply is placed is not connected to the outside world, the exchange of internal air and external air is weak, which cannot achieve a good heat dissipation effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] During operation, a plasma power supply operates at high voltage and is usually sealed to protect it from dust and other interference. A fan is then used to dissipate heat. However, since the space where the power supply is placed is not connected to the outside world, the exchange between the internal air and the external air is weak, which does not provide a good heat dissipation effect. This embodiment is specially invented to solve the above problem.

[0031] See also Figure 1 、 Figure 2 and Figure 5 As shown, a plasma deodorizing power supply according to an embodiment of the present invention comprises a plasma generator 1, a protective shell 2 is provided at the front end of the plasma generator 1, a plurality of high-voltage power supplies 3 are provided in the protective shell 2, a protective plate 4 is hingedly connected to the front side of the protective shell 2, an air inlet 201 is provided on one side of the plasma generator 1, and an air outlet 202 is provided on the side of the plasma generator 1 away from the air inlet 201; further comprising an air collecting component 5, a heat dissipation component 6 and a moisture-proof component 7; wherein the air collecting component 5 is provided on the plasma generator 1 and is located on one side of the air outlet 202 for collecting gas; the heat dissipation component 6 comprises an air outlet pipe 601 provided in the plasma generator 1, and the air outlet pipe 601 is provided with a plurality of air outlet pieces 602 respectively inserted into the upper side of the high-voltage power supply 3 ; The air collecting component 5 includes a guide cover 501 arranged in the air outlet 202, the opening of the guide cover 501 faces the air outlet 202, and a guide tube 502 is fixedly arranged on the side of the guide cover 501 away from the air outlet 202, and the free end of the guide tube 502 is inserted into the liquid collecting part 701; the heat dissipation component 6 also includes a plurality of exhaust parts 603 arranged on the lower side of the high-voltage power supply 3, and an exhaust pipe 604 is connected to the lower side of the plurality of exhaust parts 603, one end of the exhaust pipe 604 is inserted into the plasma generator 1, the shape of the guide cover 501 is trumpet-shaped, and the diameter of the side of the guide cover 501 facing the air outlet 202 is larger than the diameter of the side away from the air outlet 202; the moisture-proof component 7 also includes two staggered baffles 711 arranged in the liquid collecting part 701.

[0032] During specific operation, the high-voltage power supply 3 is started, and the high-voltage power supply 3 transmits energy to the plasma generator 1. Then, the exhaust gas enters the plasma generator 1 through the air inlet 201, ionizing the air to form positive ions and free electrons. The positive ions and free electrons react chemically with the exhaust gas to generate harmless substances such as carbon dioxide and water, so that the exhaust gas is decomposed and deodorization is completed.

[0033] The decomposed and discharged gas is discharged through the gas outlet 202, and a part of the gas enters the guide tube 502 through the guiding effect of the guide cover 501. Since the guide cover 501 is trumpet-shaped and the side with the larger opening faces the gas outlet 202, it can better guide the discharged clean gas, allowing the gas to enter the guide cover 501 and the guide tube 502, and the clean gas is discharged into the liquid collecting part 701 through the guide tube 502.

[0034] Due to the provision of staggered baffles 711, the clean gas can be prevented from directly blowing the moisture collected in the liquid collecting part 701, and the moisture can be prevented from evaporating into the air outlet pipe 601, resulting in the clean gas used for heat dissipation containing more moisture. The gas is then discharged into the exhaust part 603 through the air outlet pipe 601, and the clean gas is discharged into the interior of the high-voltage power supply 3 through the exhaust part 603 to dissipate heat from the high-voltage power supply 3.

[0035] The clean gas blown out from the plasma generator 1 is directly introduced into the high-voltage power supply 3, which can solve the problem of the high-voltage power supply 3 being in a closed space by introducing clean gas from the outside to ensure that there is no interference from dust, etc., thereby achieving a better heat dissipation effect on the high-voltage power supply 3 and solving the problem of the high-voltage power supply 3 having poor heat exchange ability with the outside world when in a closed state. The exhausted gas is discharged into the plasma generator 1 through the exhaust pipe 604, which can eliminate the original garbage inside the high-voltage power supply 3 brought out by the gas, and can improve the cleanliness of the interior of the high-voltage power supply 3.

[0036] Example 2

[0037] In actual use, it was found that there were still certain deficiencies in the above embodiment, because a small amount of reaction product moisture would be discharged into the high-voltage power supply 3 through the guide tube 502 and the air outlet pipe 601, resulting in the need to frequently dehumidify the high-voltage power supply 3, and the moisture-proof effect was poor.

[0038] In order to solve the above technical problems, based on Example 1, refer to Figures 1 to 7The moisture-proof component 7 includes a liquid collecting member 701 arranged in the plasma generator 1, an end of the air outlet pipe 601 away from the high-voltage power supply 3 is inserted into the liquid collecting member 701, a liquid collecting pipe 702 is provided on the upper end of the liquid collecting member 701, a plurality of liquid outlets 703 distributed along the extension direction of the air outlet pipe 601 and close to the upper side of the liquid collecting pipe 702 are respectively opened on the side of the liquid collecting pipe 702 close to the liquid outlet 703 are respectively opened with a plurality of liquid outlets 703 that are paired with the liquid outlet 703. The corresponding liquid inlet 704, the upper and lower opposite liquid outlets 703 and the liquid inlet 704 are connected through connecting pipes 705, the lower end of the collecting pipe 702 is inserted into the liquid collecting part 701, and the moisture-proof component 7 also includes a plurality of liquid blocking parts 716 arranged in the air outlet pipe 601, and the plurality of liquid blocking parts 716 respectively correspond to the connecting pipes 705 on their corresponding sides, and each liquid blocking part 716 is respectively located at the connection position between the connecting pipe 705 on its corresponding side and the liquid outlet 703. The moisture-proof component 7 also includes Two telescopic parts 706 are set in the liquid collecting part 701, and the part of the liquid collecting pipe 702 inserted into the liquid collecting part 701 is located between the two telescopic parts 706. A blocking part 707 is set between the two telescopic parts 706. An elastic part 708 is set between each telescopic part 706 and the liquid collecting part 701. The part of the air outlet pipe 601 located in the protective part 8 is spiral, and the liquid collecting pipe 702 is spiral. The multiple liquid outlets 703 are evenly distributed in the spiral extension direction of the air outlet pipe 601. Distribution, multiple liquid inlets 704 are evenly distributed in the spiral extension direction of the liquid collecting pipe 702, and the liquid blocking parts 716 are distributed in the spiral extension direction of the air outlet pipe 601. The side wall of the liquid blocking part 716 that rises along the spiral contacts the inner side wall of the upper end of the connecting pipe 705 that descends along the spiral. The shape of the liquid blocking part 716 is trumpet-shaped, and the end of the liquid collecting pipe 702 that is not inserted into the liquid collecting part 701 is in a sealed state, and the end of the exhaust pipe 604 that is not inserted into the plasma generator 1 is in a sealed state.

[0039] During specific use, the clean gas is discharged into the liquid collecting member 701 through the guide tube 502, and then under the action of pressure, the gas is discharged into the interior of the high-voltage power supply 3 through the air outlet pipe 601 and the exhaust member 603. Since the air outlet pipe 601 and the liquid collecting pipe 702 are spiral-shaped, and the spiral part of the air outlet pipe 601 is completely consistent with the liquid collecting pipe 702, when the gas flows in the air outlet pipe 601, the moisture therein is affected by the liquid blocking member 716 and the inner wall of the air outlet pipe 601, and continuously falls into the lower side of the inside of the air outlet pipe 601; since the moisture adheres to the inner wall of the air outlet pipe 601 , and the moisture is blocked by the liquid blocking member 716, which can prevent the moisture from flowing out of the upper part of the air outlet pipe 601, so the moisture will continue to deposit inside the air outlet pipe 601; the free end of the liquid blocking member 716 is in the shape of a thin tube, so that when the moisture in the gas rises upward along the air outlet pipe 601, the contact area with the liquid blocking member 716 is larger, which can make the moisture better gather and liquefy, and the liquid blocking member 716 is arranged on the spiral downward side of the connecting pipe 705 on its corresponding side, which can make the deposited liquid flow into the inside of the collecting pipe 702 through the liquid outlet 703, the connecting pipe 705 and the liquid inlet 704.

[0040] As the water in the collecting pipe 702 continues to accumulate and flows downward in the spiral direction of the collecting pipe 702, after reaching a certain weight, the water presses the blocking member 707 to move downward, the two elastic members 708 are stretched, the two telescopic members 706 are stretched, and part of the liquid flows from the lower side of the collecting pipe 702 to the inside of the collecting member 701, which relieves the pressure inside the collecting pipe 702 to a certain extent. After the pressure is relieved to a certain extent, the blocking member 707 moves upward to the initial position under the action of the two elastic members 708, and the two telescopic members 706 shrink synchronously, which can prevent the gas discharged into the collecting member 701 from moving upward from the collecting pipe 702 and causing the collected water to flow back. In the process of dissipating heat for the high-voltage power supply 3, the pressure relief and liquid filtration are carried out continuously to ensure that the moisture in the gas is always filtered into the collecting pipe 702 and the collecting member 701 during the heat dissipation process.

[0041] Moreover, during the process of liquid descending and air intake from the guide tube 502 into the liquid collecting part 701, the baffles 711 are tilted and staggered, which can prevent the gas entering the liquid collecting part 701 from directly blowing the collected water to form steam, and can also facilitate the liquid discharged from the liquid collecting pipe 702 to quickly flow to the lower side of the baffle 711, thereby reducing the contact between the incoming gas and the discharged water, and reducing the probability of the collected water being blown and evaporated.

[0042] Through the above embodiment, the spiral setting of the air outlet pipe 601 and the spiral setting of the liquid collecting pipe 702 can make the moisture in the gas continuously contact the side walls of the air outlet pipe 601 and the liquid collecting pipe 702, so that the moisture is discharged into the liquid collecting pipe 702, and through the connecting pipe 705 and the trumpet-shaped liquid blocking part 716, it can be ensured that the filtered moisture is discharged into the liquid collecting pipe 702, effectively reducing the moisture content of the gas, achieving excellent moisture-proof effect, reducing the number of times of manual dehumidification of the high-voltage power supply 3, and reducing the labor of the operating workers, and one end of the liquid collecting pipe 702 is closed, which can greatly reduce the probability of gas moving upward from the liquid collecting pipe 702, and can intermittently open the blocking part 707 to allow the collected liquid to be discharged into the liquid collecting part 701, effectively preventing a large amount of gas from being directly transported upward from the liquid collecting pipe 702, thereby ensuring the filtering effect of moisture.

[0043] Example 3

[0044] After filtering the water, the liquid needs to be discharged to prevent the collected liquid from being kept inside the liquid collecting member 701, causing the internal water level to be too high, reducing the water filtering effect, and increasing the number of manual dehumidification times.

[0045] In order to solve the above technical problems, based on the embodiment 1 and the embodiment 2, refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 It can be seen that the adopted technical solution includes a moisture-proof component 7, which also includes two staggered baffles 711 arranged in the liquid collecting part 701, and a liquid level sensor 712 located below the baffle 711 on the lower side is provided in the liquid collecting part 701. The liquid level sensor 712 is used to detect the liquid height in the liquid collecting part 701, and a solenoid valve 713 is provided at the lower end of the liquid collecting part 701. A drain pipe 714 connected to the solenoid valve 713 is provided at the lower end of the liquid collecting part 701, and a protective part 8 is provided at the upper end of the liquid collecting part 701. A controller 715 is provided on the protective part 8, and the controller 715 is used to control the opening and closing of the solenoid valve 713. A part of the air outlet pipe 601 is located in the protective part 8, and the liquid collecting pipe 702 is located in the protective part 8.

[0046] When the water level in the liquid collecting member 701 reaches a set level, detected by the liquid level sensor 712, the liquid level sensor 712 sends a signal to the controller 715, which controls the opening of the solenoid valve 713. The collected water is then discharged to the outside through the drain pipe 714. A bucket or other container can be placed below the drain pipe 714 to contain the liquid discharged from the drain pipe 714, preventing the liquid from being discharged into the surrounding area and forming moisture, or otherwise affecting the operating environment of the machine. A protective member 8 is provided within the plasma generator 1, so that a portion of the air outlet pipe 601 and the liquid collecting pipe 702 are located within the protective member 8. This protects the air outlet pipe 601 and the liquid collecting pipe 702 from being affected within the plasma generator 1.

[0047] As the liquid is discharged, the gas discharged from the flow guide tube 502 exerts a certain downward pressure, accelerating the discharge of the liquid from the liquid collecting member 701 and improving drainage efficiency. When the liquid level sensor 712 detects that the water in the liquid collecting member 701 has been drained or only a small amount of water remains, the liquid level sensor 712 sends a signal to the controller 715, causing the controller 715 to control the solenoid valve 713 to close, stopping the discharge of liquid and preventing gas from being discharged through the opening of the solenoid valve 713, which would affect the heat dissipation efficiency. The pressure in the liquid collecting member 701 returns to a stable state.

[0048] Through the cooperation of the solenoid valve 713, the liquid level sensor 712 and the controller 715, after the liquid in the liquid collecting part 701 reaches a certain water level, the liquid in the liquid collecting part 701 is discharged in equal amounts to achieve the purpose of quantitative drainage, thereby preventing the high moisture content in the gas from causing rapid accumulation of moisture and the inability to quickly discharge the moisture. It can also prevent the water level from accumulating too high, resulting in a decrease in filtration efficiency and an increase in the number of manual dehumidification operations. In addition, by setting up the protective part 8, the air outlet pipe 601 and the liquid collecting pipe 702 can be protected from the influence inside the plasma generator 1.

[0049] The plasma generator 1, high voltage power supply 3, liquid level sensor 712, solenoid valve 713, controller 715 and their connection methods in the present invention are all prior art and will not be described in detail here.

[0050] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
