Description

Technical Field

[0001] This utility model relates to the field of electrode protection device technology, and in particular to an electrode protection device for a plasma air sterilizer. Background Technology

[0002] In modern society, air disinfection plays a crucial role in safeguarding public health and human well-being. However, traditional air disinfection technologies can be harmful to the human body. Against this backdrop, plasma air disinfection technology has emerged. As an advanced air disinfection device, plasma air sterilizers offer extremely strong disinfection effects and short action times. Their working principle is based on the unique physicochemical properties of plasma. On one hand, negatively charged bacteria are repelled by electrons and drawn towards positive ions, becoming surrounded and impregnated by them. A sufficient number of positive ions penetrate the cell wall, destroying the cell membrane and cellular electrolytes, leading to cell death. On the other hand, the large amount of ultraviolet light released during plasma generation simultaneously attracts charged bacteria to the positive electrode. The accumulation of positive ions increases the potential difference of the cell membrane until it breaks down, destroying intracellular electrolytes. Plasma air sterilizers possess significant advantages such as high-efficiency sterilization, environmental friendliness, human-machine coexistence, low energy consumption, and long service life, and are widely used in various fields including medical and health care, biopharmaceuticals, food production, and public places. During the operation of a plasma air sterilizer, the electrodes, as key components, play a crucial role in generating plasma. However, due to the complex working environment, the electrodes are susceptible to damage from various factors, which in turn affects the performance and service life of the sterilizer. Therefore, electrode protection devices have become an important component in ensuring the stable operation of the plasma air sterilizer.

[0003] Electrode protection devices typically consist of a protective shell, insulating components, and a heat dissipation structure. The protective shell prevents direct impact and erosion of the electrode by external objects. The insulating components are usually made of materials with excellent insulation properties to prevent leakage. The heat dissipation structure dissipates the heat generated during electrode operation to prevent performance degradation due to overheating. However, existing electrode protection devices have drawbacks. While the protective shell can block foreign objects, dust and microorganisms accumulate on its surface during long-term use, affecting the gas environment around the electrode and reducing plasma generation efficiency. Furthermore, the insulating components experience a decline in insulation performance under harsh environments with high humidity and high voltage, posing a risk of leakage. To address these drawbacks, existing technologies use special textures and coatings on the protective shell surface to reduce dust adsorption and employ insulating structures with better sealing performance to prevent moisture intrusion. However, the adsorption effect of the special textures and coatings gradually weakens after long-term use, making it difficult to effectively remove dust from the protective shell surface. Moreover, existing devices use water for heat dissipation, which can easily lead to leakage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electrode protection device for a plasma air sterilizer, which aims to improve the existing technology's inability to effectively remove dust from the surface of the protective shell and the tendency to cause leakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electrode protection device for a plasma air sterilizer, comprising a base, a protective shell fixedly connected to the top of the base, an L-shaped plate fixedly connected to the front side of the protective shell, a motor fixedly connected to the left side of the L-shaped plate, a connecting shaft fixedly connected to the output end of the motor, an elongated plate rotatably connected to the left side of the connecting shaft, a gear fixedly connected to the outer wall of the connecting shaft, a rack meshing with the outer wall of the gear, a mounting plate fixedly connected to the top of the rack, multiple brush heads fixedly connected to the rear side of the mounting plate, a sliding plate fixedly connected to the bottom of the rack, a fixing plate fixedly connected to the top front side of the base, the fixing plate and the sliding plate being slidably connected, and a heat dissipation mechanism fixedly connected to the top of the protective shell.

[0006] As a further description of the above technical solution:

[0007] The heat dissipation mechanism has a base plate fixedly connected to its top, and the bottom of the base plate fixedly connected to the top of the protective shell. Multiple heat dissipation fins are fixedly connected inside the base plate. Heat pipes are connected to both the left and right sides of the base plate. A liquid storage tank is fixedly connected to the top of the protective shell. A connecting pipe is connected to the front of the liquid storage tank. A circulation pump is fixedly connected to the front of the connecting pipe. A liquid outlet pipe is connected to the right side of the circulation pump. A liquid collection pipe is fixedly connected to the right side of the liquid outlet pipe. Multiple nozzles are connected to the right side of the liquid collection pipe.

[0008] As a further description of the above technical solution:

[0009] The liquid storage tank has an injection port on the top, and the injection port is covered with a cover plate.

[0010] As a further description of the above technical solution:

[0011] The bottom of the base is fixedly connected to multiple anti-slip pads, and the top of the base is fixedly connected to a vacuum cleaner.

[0012] As a further description of the above technical solution:

[0013] The vacuum cleaner has a suction tube connected to its right side, and a dust collection tank is fixedly connected to the right side of the suction tube.

[0014] As a further description of the above technical solution:

[0015] A support column is fixedly connected to the top of the base, and a circular plate is fixedly connected to the top of the support column.

[0016] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the electrode is placed inside the protective shell, and then the motor is turned on, so that the connecting shaft drives multiple gears to rotate, causing the rack to rise and fall inside the fixed plate, thereby driving the brush head on the back of the mounting plate to rise and fall, which can achieve the function of brushing away the dust on the surface of the protective device, while avoiding scratching the shell and improving the plasma generation efficiency.

[0022] 2. In this invention, the liquid inside the heat pipe is deionized water. Deionized water has extremely weak conductivity. When the left and right ends of the heat pipe are heated, the deionized water absorbs heat and evaporates into steam. Under the action of the pressure difference inside the pipe, the steam flows rapidly towards the substrate. The cooling deionized water inside the circulating pump is sprayed onto the surface of the heat dissipation fins through the nozzle under the action of the connecting pipe. The steam condenses into liquid after encountering the cooling of the substrate, releasing the heat of vaporization. The liquid then flows back to the protective shell through the heat pipe. This cycle repeats, realizing the rapid transfer of heat and achieving the function of efficiently dissipating the heat of the electrode without causing leakage, thus improving efficiency.
