[0040] The following further describes in detail the embodiments of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0041] In the description of the embodiments of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] In the description of the embodiments of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific situations.

[0043] In the embodiments of the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "below" and "beneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0044] In the description of this specification, the descriptions with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0045] It can be understood that the types of refrigeration equipment include refrigerators, freezers, etc. Taking the refrigerator as an example, the odor and bacteria removal device is generally used inside the refrigerator, and its main function is to remove odors and bacteria. Therefore, plasma or negative ion sterilization technology is generally adopted, that is, high-voltage electric field sterilization. For the components used inside the refrigerator, to ensure safety, the high-voltage ion generator circuit that generates the high-voltage electric field is generally potted and sealed to prevent water vapor from entering. Because of the potting process, the currently used potting materials are mainly epoxy resin or polyurethane. In order to ensure the full sealing of the potting and at the same time exclude the intermediate space, the viscosity of the glue is relatively low. For the upright high-voltage ion generator, its bottom box uses a fully sealed paper, while for the side placement, since the electrode pin 221 needs to pass through one side of the enclosure, glue will flow out, resulting in glue leakage; to avoid glue leakage, generally lead wires are taken from the high-voltage ion generator to outside the enclosure, and an electrode fixing structure is designed outside the enclosure. In this way, the fixing box of the high-voltage ion generator is a fully enclosed design to avoid glue leakage, but the problem brought by this structure is that the structural design is complex.

[0046] The following will be combined with Figures 1-6 Describe the sterilization component, odor and bacteria removal device and refrigeration equipment of the embodiments of the present utility model. It can be understood that in the embodiments of the present utility model, the odor and bacteria removal device includes the above-mentioned sterilization component, and the refrigeration equipment includes the above-mentioned odor and bacteria removal device. Taking the refrigerator as an example, the odor and bacteria removal device is installed in the air duct of the refrigerator.

[0047] Referring to Figures 1 to 4 and Figure 6 Figure 6 , the sterilization component according to the embodiment of the present utility model includes a first housing 100, a controller 210, an electrode unit 220 and a high-voltage power supply 230. The first housing 100 is provided with a first installation cavity 110 and a first channel 120. The controller 210 is arranged in the first installation cavity 110. One end of the electrode unit 220 is located in the first installation cavity 110 and is electrically connected to the controller 210. The other end of the electrode unit 220 passes through the first channel 120. The high-voltage power supply 230 is arranged in the first installation cavity 110. The high-voltage power supply 230 is electrically connected to the controller 210, and the high-voltage power supply 230 is used to supply power to the electrode unit 220; wherein, the first housing 100 is provided with a first fixing structure 130, and the electrode unit 220 is provided with a second fixing structure 223. The first fixing structure 130 and the second fixing structure 223 are clamped and matched with each other, and the second fixing structure 223 can close the first channel 120.

[0048] For the sterilization component according to the embodiment of the present utility model, under the drive of the controller 210, the high-voltage power supply 230 supplies power to the electrode unit 220 to excite plasma for sterilization. Through the mutual cooperation of the first fixing structure 130 and the second fixing structure 223, the electrode unit 220 is relatively fixed to the first housing 100. And when potting the circuit area of the controller 210 in the first installation cavity 110, since the second fixing structure 223 closes the first channel 120, it prevents glue from leaking out from the first channel 120, improves the tightness, and has a simple structure and convenient operation.

[0049] It can be conceived that in the embodiment of the present utility model, the controller 210 is respectively connected to the high-voltage power supply 230 and the electrode unit 220 to control the intermittent operation of the electrode unit 220, ensure the stable operation of the electrode unit 220, avoid the electrode unit 220 being in an operating state all the time, so as to increase its service time and reduce its service life.

[0050] It should also be noted that referring to Figures 1 to 6 Figures 1 to 6 , in the embodiment of the present utility model, the odor removal and sterilization device further includes a second housing 300, a fan 500 and an odor removal catalyst module 600. The second housing 300 is connected to the first housing 100, and an installation chamber, an air inlet 410 and an air outlet 420 are defined between the second housing 300 and the first housing 100. The fan 500 is arranged in the installation chamber; the odor removal catalyst module 600 is arranged in the installation chamber. When the air flow flows between the air inlet 410 and the air outlet 420, it passes through part of the structures of the odor removal catalyst module 600 and the electrode unit 220. It can be understood that the air inlet side of the odor removal catalyst module 600 corresponds to the air inlet 410, and the air outlet side of the odor removal catalyst module 600 corresponds to the air outlet 420.

[0051] Specifically, in an embodiment of the utility model, the installation chamber is provided with a first installation area and a second installation area, the air inlet 410 is located on one side of the first installation area, and the air outlet 420 is located on a side of the second installation area away from the first installation area. The first installation area is used to install the fan 500, and the controller 210, the electrode unit 220, the high-voltage power supply 230 and the deodorizing catalyst module 600 are all arranged in the second installation area. With the above arrangement, the fan 500, the controller 210, the electrode unit 220, the high-voltage power supply 230 and the deodorizing catalyst module 600 are integrated with each other in the first shell 100 and the second shell 300, thereby forming an integrated structure, so as to greatly reduce the structural size of the deodorizing sterilization device. On the basis of not reducing the original deodorizing sterilization effect, it is beneficial to reduce the total occupied volume, the equipment is simple, the fixing cost is low, the centralized layout breaks through the design limitations, and is conducive to promotion and application.

[0052] It should be noted that, in this embodiment, the controller 210 is a high-voltage ion generator, and the electrode unit 220 is an electrode net. The controller 21 is electrically connected to the electrode net and the fan 500, which reduces the control components and improves the assembly efficiency. Of course, in some embodiments, the controller 210 is a fan control board, which is electrically connected to the fan control board through the fan 500, and the electrode unit 220 of the odor-removing and sterilizing mechanism is electrically connected to the fan control board, which is not limited here.

[0053] Specifically, refer to Figures 1 to 4 as well as Figure 6 In the embodiment of the utility model, the first shell 100 is provided with a partition baffle 150, and the second installation area is separated into a first installation cavity 110 and a second installation cavity 140 by the partition baffle 150; the controller 210 is arranged in the first installation cavity 110, and the deodorizing catalyst module 600 is arranged in the second installation cavity 140. One end of the electrode unit 220 is electrically connected to the controller 210, and the other end is passed through the partition baffle 150 and extends into the second installation cavity 140. By setting the partition baffle 150, it is divided into the first installation cavity 110 and the second installation cavity 140, and different components are placed in the corresponding cavities. The spatial separation helps to isolate different components and functions to avoid mutual interference or cross-influence. The controller 210 and the deodorizing catalyst module 600 are respectively arranged in different cavities to ensure their independent operation and improve the performance and effect of the overall system. The electrode unit 220 can be electrically connected to the controller 210 and transport charged particles to the second mounting cavity 140, so that the electrode unit 220 can release a high voltage electric field in the second mounting cavity 140 to achieve a sterilization effect. At the same time, the presence of the partition baffle 150 ensures the separation between the electrode unit 220 and other components to avoid interference with the electric field or interference with other functions.

[0054] It should be noted that, in this embodiment, the partition baffle 150 and the first housing 100 are of an integral structure, and the partition baffle 150 is disposed around the first installation cavity 110. The partition baffle 150 is provided with a first channel 120 communicating with the first installation cavity 110 and the second installation cavity 140.

[0055] Specifically, referring to Figure 1 , in the embodiment of the present utility model, one side of the first installation area for installing the fan 500 is in through communication with one side of the second installation cavity 140, and the air outlet 420 is disposed on the other side opposite to the second installation cavity 140. When the air flow flows between the air inlet 410 and the air outlet 420, it passes through part of the structures of the second installation cavity 140, the odor removal catalyst module 600, and the electrode unit 220. It can be understood that the air inlet side of the odor removal catalyst module 600 corresponds to the air inlet 410, and the air outlet side of the odor removal catalyst module 600 corresponds to the air outlet 420.

[0056] With the above settings, through the through communication between the first installation area and the second installation cavity 140, the air flow at the air inlet 410 can enter the second installation cavity 140. Then, the air flow flows in the second installation cavity 140 and passes through part of the structures of the odor removal catalyst module 600 and the electrode unit 220. When the air flow passes through the second installation cavity 140, through the action of the odor removal catalyst module 600, odor substances can be decomposed to improve the freshness of the air. The catalyst substances in the odor removal catalyst module 600 can accelerate the chemical reaction of the odor substances and convert them into harmless substances or substances with a lighter smell. Therefore, when the air flow passes through the odor removal catalyst module 600, the odor substances can be effectively treated and deodorized; the electrode unit 220 releases charged particles, such as electrons and ions, by providing a high-voltage electric field. 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 420 of the second installation cavity 140, thereby providing a fresher and more hygienic air environment.

[0057] It can be understood that, referring to Figures 1 to 4 and Figure 6, in the embodiment of the present utility model, the controller 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 electrode unit 220 is further provided with a first fixing seat 222. The plurality of electrode pins 221 are connected to the same first fixing seat 222, and the first fixing seat 222 abuts against the controller 210 to limit the relative movement of the electrode unit 220 with respect to the controller 210. It can be understood that the above-mentioned controller 210 is a high-voltage ion generator, and the electrode unit 220 is an electrode net. The high-voltage ion generator has a control board. When the first fixing seat 222 is inserted into the insertion position 211 of the control board of the controller 210, the first fixing seat 222 abuts against the control board of the controller 210.

[0058] With the above arrangement, by using a plurality of electrode pins 221 arranged side by side as the basic mesh electrodes, the plurality of electrode pins 221 are installed in the insertion position 211 by an insertion method, and the relative movement of the electrode unit 220 with respect to the controller 210 is restricted by the first fixing seat 222, fixing the relative positions of the electrode unit 220 and the controller 210. Therefore, through the cooperation of the insertion method and the first fixing seat 222, the structure of the sterilization component is simplified, the installation efficiency is high, and the manufacturing cost is relatively low.

[0059] Specifically, referring to Figure 4 , in this embodiment, the first fixing seat 222 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 position.

[0060] Specifically, referring to Figure 4 , in this embodiment, the first fixing seat 222 is a plastic part, with a simple structure, lightweight, good insulation and corrosion resistance, and low manufacturing cost.

[0061] Specifically, referring to Figure 4 , in this embodiment, the first fixing seat 222 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 222 and the electrode pins 221, simplifies the assembly process, can save time and labor, and reduces possible errors during the assembly process, optimizes the electrical performance and reduces the number of components.

[0062] It can be understood that, referring to Figures 1 to 4, in the present practical embodiment, the first fixing structure 130 is a fixing table, the fixing table is provided with a fixing groove 131, one side wall of the fixing groove 131 is provided with a second channel, and the first channel 120 communicates with the other side wall opposite to the fixing groove 131; the second fixing structure 223 is a second fixing base, the second fixing base is fitted with the fixing groove 131 in a clamping manner, and the side wall area of the second fixing base facing the first channel 120 is larger than the cross-sectional area of the first channel 120.

[0063] With the above arrangement, through the clamping fit between the fixing groove 131 and the second fixing base, a fixed and positioned connection is formed between the first fixing structure 130 and the second fixing structure 223. The fixing groove 131 of the fixing table provides a fixed position, while the second fixing base ensures a stable connection between the first fixing structure 130 and the second fixing structure 223 through the clamping fit in the fixing groove 131, defines their relative positions, and restricts the second fixing base from moving into the first channel 120 by the side wall area of the second fixing base being larger than the cross-sectional area of the first channel 120, and it is convenient to close the first channel 120 for sealing and potting.

[0064] It should be noted that, in some embodiments, the height of the second fixing base is adapted to the height of the fixing groove 131, or when the height of the second fixing base is lower than the height of the fixing groove 131, the second fixing structure 223 further includes a fixing plug, the fixing plug is installed in the fixing groove 131, and the fixing plug cooperates with the second fixing base to jointly close the first channel 120 and block the communication between the first installation cavity 110 and the second installation cavity 140; the cross-section of the second fixing base is rectangular, and the shapes of the fixing groove 131 and the second fixing base are adapted to limit the rotation of the second fixing base relative to the fixing groove 131 and improve the assembly stability.

[0065] It can be understood that referring to Figure 6 , in the embodiment of the present utility model, guiding inclined surfaces 1311 are respectively provided on the two opposite side walls of the fixing groove 131, and the guiding inclined surfaces 1311 are used to guide the second fixing structure 223 to be inserted into the fixing groove 131. When the second fixing structure 223 is inserted, the guiding inclined surfaces 1311 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 131. Through the action of the guiding inclined surfaces 1311, the insertion process becomes simpler and more accurate.

[0066] Specifically, referring to Figure 4, in the embodiment of the present utility model, the second fixing seat and the plurality of electrode pins 221 of the electrode unit 220 are integrally injection-molded, providing strength and stability. The integrated structure eliminates the steps of separately installing and fixing the second fixing seat and the electrode pins 221, simplifies the assembly process, can save time and labor, and reduces the possible errors during the assembly process, optimizes the electrical performance, and reduces the number of components. Of course, in some embodiments, the above-mentioned second fixing seat and the plurality of electrode pins 221 may also be of a split structure, which is not limited herein.

[0067] Specifically, referring to Figure 5 , in the embodiment of the present utility model, the first housing 100 and the second housing 300 are detachably connected, and the first housing 100 and the second housing 300 cooperate to form an installation cavity, which can be conveniently separated and connected, making it more convenient for maintenance, cleaning or replacement of components, and can also simplify the manufacturing and assembly processes and improve production efficiency. It should be noted that the way the first housing 100 and the second housing 300 are detachably connected can be a snap connection method, a bolt connection method, etc., which is not limited herein.

[0068] Specifically speaking, referring to Figure 1 and Figure 2 , in the embodiment of the present utility model, a limiting structure is provided in the second installation concave cavity 140, and the limiting structure cooperates with the second installation concave cavity 140 to define an installation space for installing the odor removal catalyst module 600. With the above structure, the installation space of the odor removal catalyst module 600 can be defined. The design and shape of the limiting structure match the odor removal catalyst module 600, ensuring that the odor removal catalyst module 600 is installed in the correct position and preventing it from moving or falling off during use, ensuring that the odor removal catalyst module 600 can effectively perform its function, while simplifying the installation process, increasing the stability of the odor removal catalyst module 600, and facilitating maintenance.

[0069] Specifically, referring to Figure 1 and Figure 2, in the embodiment of the present utility model, the limiting structure includes a first limiting plate 161, a second limiting plate 162, a third limiting plate 163 and a fourth limiting plate 164. The first limiting plate 161 and the second limiting plate 162 are spaced on one side of the second installation cavity 140, and the third limiting plate 163 and the fourth limiting plate 164 are spaced on the opposite side of the second installation cavity 140. Among them, the first limiting plate 161, the second limiting plate 162, the third limiting plate 163 and the fourth limiting plate 164 cooperate with each other and enclose an installation space with the bottom wall of the second installation cavity 140. Through the above arrangement, the first limiting plate 161, the second limiting plate 162, the third limiting plate 163 and the fourth limiting plate 164 cooperate with each other to form a space for installing the odor removal catalyst module 600, which can be firmly fixed in the installation space, further improving its stability in the installation space, enhancing its working effect and reliability, with a simple structure and being easy to manufacture.

[0070] It can be understood that, referring to Figure 1 , in the embodiment of the present utility model, a positioning structure is provided in the first installation cavity 110 of the second installation area. The positioning structure is used to cooperate with the controller 210 to define the relative position between the controller 210 and the first installation cavity 110 of the second installation area, which can ensure the stable fixation and correct positioning of the controller 210, improve the stability and reliability of the device, and simplify the installation process.

[0071] Specifically, referring to Figure 1 , in the embodiment of the present utility model, the positioning structure includes a first positioning portion 171 and a second positioning portion 172.

Among them, the first positioning portion 171 is a positioning groove, and the positioning groove is inserted and matched with one end of the controller 210. The second positioning portion 172 is a supporting boss, and the supporting boss is in abutting cooperation with the opposite side surface of the control board of the controller 210. The manufacturing process can be simplified. Through appropriate processing and assembly, the positioning groove, the supporting boss and the inner wall of the first installation cavity 110 are made to match each other, restricting the horizontal movement of the controller 210 in the direction towards the second installation cavity 140, for stable connection and accurate positioning.
