[0042] It can be understood that in the related art, a high-voltage ion generator is connected with an electrode, and the form of the electrode generally adopts a needle electrode or a mesh electrode. Among them, the needle electrode is generally a dedicated design, and the manual plug-in method is adopted during the production of the circuit board of the high-voltage ion generator; for the mesh electrode, it is generally connected by leading wires from the circuit board of the high-voltage ion generator to the mesh electrode, and the installation efficiency is low. For the needle electrode, due to its dedicated design, the cost is high. At the same time, compared with the mesh electrode, the electric field space is small, which is not conducive to the generation of high-voltage ions, while the mesh electrode is because the equipment is complex.

[0043] The following combines Figures 1 - 5 to describe the high-voltage generating mechanism, the odor removal and sterilization device, and the refrigerator of the embodiments of the present utility model. It can be understood that in the embodiments of the present utility model, the odor removal and sterilization device includes a housing assembly 100, a high-voltage generating mechanism, an odor removal catalyst module 300, and a fan 400. The refrigerator includes the above-mentioned odor removal and sterilization device, and the odor removal and sterilization device is installed in the air duct of the refrigerator.

[0044] Referring to Figure 1 and Figure 2 , the high-voltage generating mechanism according to the first aspect embodiment of the present utility model includes a circuit board 210, an electrode unit 220, and a first fixing seat 230. The circuit board 210 is provided with an insertion position 211. The electrode unit 220 includes a plurality of electrode pins 221 arranged side by side. The plurality of electrode pins 221 are inserted into and electrically connected to the insertion position 211. The first fixing seat 230 is connected to the plurality of electrode pins 221, and the first fixing seat 230 abuts against the circuit board 210 to limit the relative movement of the electrode unit 220 with respect to the circuit board 210.

[0045] It should be noted that the above-mentioned circuit board 210 is applied to a high-voltage ion generator.

[0046] According to the high-voltage generating mechanism of the embodiment of the present utility model, with the above structure, by using a plurality of electrode pins 221 arranged side by side as a basic mesh electrode, the plurality of electrode pins 221 are installed at the insertion position 211 by insertion, and the relative movement of the electrode unit 220 with respect to the circuit board 210 is restricted by the first fixing seat 230, fixing the relative positions of the electrode unit 220 and the circuit board 210. Therefore, by cooperating the insertion method with the first fixing seat 230, the structure of the high-voltage generating mechanism is simplified, the installation efficiency is high, and the manufacturing cost is relatively low.

[0047] Specifically, referring to Figure 1 and Figure 2 , in this embodiment, the first fixing seat 230 is sleeved on the outer walls of the plurality of electrode pins 221, providing support and retention for the electrode pins 221 to ensure that they are stably fixed in the correct positions. Specifically, referring to the figure, in this embodiment, the first fixing seat 230 is a plastic part, with a simple structure, light weight, good insulation and corrosion resistance, and relatively low manufacturing cost.

[0048] Specifically, referring to Figure 1 and Figure 2 , in this embodiment, the first fixing seat 230 and the plurality of electrode pins 221 are of an integral structure, providing strength and stability. The integral structure eliminates the steps of separately installing and fixing the first fixing seat 230 and the electrode pins 221, simplifies the assembly process, can save time and labor, and reduces the possible errors in the assembly process, optimizes the electrical performance and reduces the number of components.

[0049] It can be understood that, referring to Figures 1 to 5 , the housing assembly 100 is provided with an installation chamber 110, an air inlet 120 and an air outlet 130. The air inlet 120 and the air outlet 130 are respectively communicated with the installation chamber 110. The high-voltage sterilization mechanism is arranged in the installation chamber 110. When the air flow flows between the air inlet 120 and the air outlet 130, it passes through part of the structure of the electrode unit 220. With the above arrangement, the electrode unit 220 provides a high-voltage electric field to release charged particles, such as electrons and ions. These charged particles can destroy the cell structure and function of microorganisms to achieve a sterilization effect. Therefore, when the air flow passes through the electrode unit 220, the microorganisms will be killed by the action of the electric field. Finally, the air flow is discharged from the air outlet 130 of the second installation concave cavity 1122, thereby providing a fresher and more hygienic air environment.

[0050] Specifically, referring to Figure 4 and Figure 5, in the embodiment of the present utility model, the high-pressure sterilization mechanism further includes a second fixing seat 240. The second fixing seat 240 is connected to a plurality of electrode pins 221, and the second fixing seat 240 is located on one side of the first fixing seat 230; the housing assembly 100 is provided with a fixing groove 140, and the fixing groove 140 is in snap-fit connection with the second fixing seat 240 to limit the relative position between the electrode unit 220 and the housing assembly 100. During assembly, through the mutual cooperation of the fixing groove 140 and the second fixing seat 240, the electrode unit 220 is relatively fixed to the housing assembly 100, with a simple structure, convenient operation and reliable positioning.

[0051] It can be understood that, with reference to Figure 4 and Figure 5 , in the embodiment of the present utility model, the cross-section of the second fixing seat 240 is rectangular, and the shapes of the fixing groove 140 and the second fixing seat 240 are adapted to each other to limit the rotation of the second fixing seat 240 relative to the fixing groove 140, thereby improving the stability of assembly;

[0052] In the embodiment of the present utility model, guiding inclined surfaces 141 are respectively provided on two opposite side walls of the fixing groove 140. The guiding inclined surfaces 141 are used to guide the second fixing structure to be inserted into the fixing groove 140. When the second fixing structure is inserted, the guiding inclined surfaces 141 will guide it to move along the direction of the inclined surface, so that it is aligned with the corresponding part in the fixing groove 140. Through the action of the guiding inclined surfaces 141, the insertion process becomes simpler and more accurate.

[0053] It can be understood that, with reference to Figure 1 , Figure 2 and Figure 4 , in the embodiment of the present utility model, the second fixing seat 240 is a plastic part, with a simple structure, light weight, good insulation and corrosion resistance, and low manufacturing cost.

[0054] Specifically, with reference to Figure 1 , Figure 2 and Figure 4 , in the embodiment of the present utility model, the second fixing seat 240 and the plurality of electrode pins 221 of the electrode unit 220 are of an integral structure, providing strength and stability.

[0055] It can be understood that, with reference to Figures 1 to 4, in the embodiment of the present utility model, the odor-removing and sterilizing device includes an odor-removing catalyst module 300. The odor-removing catalyst module 300 is disposed in the installation chamber 110, and a partial structure of the electrode unit 220 is disposed on one side of the odor-removing catalyst module 300. Among them, there is a spacing between the multiple electrode pins 221 of the electrode unit 220 and the odor-removing catalyst module 300, which can reduce unnecessary contact and mutual interference, thereby reducing the risk of air ignition that may be caused.

[0056] Specifically, referring to Figures 1 to 4 , the high-voltage sterilization mechanism further includes a third fixing seat 250. The third fixing seat 250 is connected to the multiple electrode pins 221, and the third fixing seat 250 is used to keep a spacing between the multiple electrode pins 221 and the odor-removing catalyst module 300. Among them, the first fixing seat 230, the second fixing seat 240, and the third fixing seat 250 are arranged in sequence along the length direction of the electrode pins 221. With the above arrangement, by using the third fixing seat 250 to keep a spacing between the multiple electrode pins 221 and the odor-removing catalyst module 300, unnecessary contact and mutual interference can be reduced, thereby reducing the risk of air ignition that may be caused. And arranging the first fixing seat 230, the second fixing seat 240, and the third fixing seat 250 in sequence along the length direction of the electrode pins 221 can effectively support the electrode pins 221, keeping them straight and balanced throughout their entire length, which helps to evenly distribute the electric field, improving the sterilization efficiency and effect.

[0057] Similarly, it should be noted that referring to Figure 1 and Figure 2 , in this embodiment, the third fixing seat 250 is a plastic part, with a simple structure, light weight, good insulation and corrosion resistance, and low manufacturing cost. The third fixing seat 250 and the multiple electrode pins 221 of the electrode unit 220 are of an integral structure, providing strength and stability. The integral structure eliminates the steps of separately installing and fixing the third fixing seat 250 and the electrode pins 221, simplifies the assembly process, can save time and labor, and reduces the possible errors in the assembly process, optimizes the electrical performance and reduces the number of components.

[0058] It should be noted that referring to Figures 1 to 4 , in the embodiment of the present utility model, there are two groups of electrode units 220. The two groups of electrode units 220 are arranged at intervals, and the two groups of electrode units 220 are electrically connected to the circuit board 210. Among them, one group of electrode units 220 is located on the air inlet side of the odor-removing catalyst module 300, and the other group of electrode units 220 is located on the air outlet side of the odor-removing catalyst module 300. Through the above arrangement, two-way treatment of air can be achieved. The electrode unit 220 on the air inlet side can be used to remove pollutants or odors in the air, while the electrode unit 220 on the air outlet side can further purify the air to ensure the freshness and cleanliness of the outlet air.

[0059] It is understandable that, with reference to Figure 3 and Figure 4 , in the embodiment of the present utility model, the blower 400 is disposed in the installation chamber 110. The blower 400 conveys air flow to the odor removal catalyst module 300 and the high-voltage generating mechanism to improve the working efficiency.

[0060] Specifically, with reference to Figure 3 and Figure 4 , in the embodiment of the present utility model, the housing assembly 100 includes a first housing 150 and a second housing 160. The first housing 150 and the second housing 160 are detachably connected, and the first housing 150 and the second housing 160 cooperate to form an installation chamber 110, which can be conveniently separated and connected, making it more convenient for maintenance, cleaning or replacement of components, without the need to disassemble the entire housing assembly 100. It can also simplify the manufacturing and assembly processes and improve production efficiency. It should be noted that the corresponding concave positions of the above-mentioned first housing 150 and second housing 160 form the installation chamber 110 when the two are connected. It should be noted that the detachable connection method of the first housing 150 and the second housing 160 can be a snap connection method, a bolt connection method, etc., which is not limited herein.

[0061] It should be noted that, with reference to Figures 3 to 5 , in the embodiment of the present utility model, the installation chamber 110 is provided with a first installation area 111 and a second installation area 112. The air inlet 120 is located on one side of the first installation area 111, and the air outlet 130 is located on the side of the second installation area 112 away from the first installation area 111. The first installation area 111 is used to install the blower 400, and the high-voltage generating mechanism and the odor removal catalyst module 300 are both disposed in the second installation area 112.

[0062] Specifically speaking, with reference to Figures 3 to 5, in the embodiment of the present utility model, the first housing 150 is provided with a partition baffle 1123, and the second installation area 112 is divided into a first installation cavity 1121 and a second installation cavity 1122 by the partition baffle 1123; the circuit board 210 is arranged in the first installation cavity 1121, the odor purification catalyst module 300 is arranged in the second installation cavity 1122, one end of the electrode unit 220 is electrically connected to the circuit board 210, and the other end penetrates through the partition baffle 1123 and extends into the second installation cavity 1122. By providing the partition baffle 1123, it is divided into the first installation cavity 1121 and the second installation cavity 1122, and different components are arranged in the corresponding cavities. The spatial separation helps to isolate different components and functions, avoiding mutual interference or cross-influence. For example, in the odor purification and sterilization mechanism, setting the circuit board 210 and the odor purification catalyst module 300 in different cavities can ensure their independent operation and improve the performance and effect of the overall system. The electrode unit 220 can be electrically connected to the circuit board 210 and transport charged particles into the second installation cavity 1122. In this way, the electrode unit 220 can release a high-voltage electric field in the second installation cavity 1122 to achieve the sterilization effect. At the same time, the existence of the partition baffle 1123 ensures the separation between the electrode unit 220 and other components, avoiding the interference of the electric field or interfering with other functions.

[0063] Specifically, referring to Figures 3 to 5 , in the embodiment of the present utility model, one side of the first installation area 111 is communicated with one side of the second installation cavity 1122, and the air outlet 130 is arranged on the other opposite side of the second installation cavity 1122. When the air flow flows between the air inlet 120 and the air outlet 130, it passes through the second installation cavity 1122, the odor purification catalyst module 300, and a part of the structure of the electrode unit 220. It can be understood that the air inlet side of the odor purification catalyst module 300 corresponds to the air inlet 120, and the air outlet side of the odor purification catalyst module 300 corresponds to the air outlet 130.
