Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically to a safe disinfection cabinet. Background Technology
[0002] Existing sterilizers typically consist of a cabinet with an inner liner and a door that can be opened or closed. When using the sterilizer to disinfect utensils, users place the utensils inside the liner, close the door, and then the hot air fan and UV lamp activate to sterilize the utensils. Currently, most sterilizers on the market place the UV lamp on the inner wall of the liner. However, when users open the cabinet to remove utensils, the ultraviolet rays can easily irradiate the user, potentially harming their eyes, skin, and other areas. Therefore, for user health and safety, a small baby bottle sterilizer, as disclosed in Chinese patent CN202020471682.5, features a micro-motion structure on the connection surface between the door and the cabinet body to control the operation of the UV lamp. When the door is open, the micro-motion structure cuts off the power supply to the UV lamp; when the door is closed, the micro-motion structure connects the power supply to the UV lamp, ensuring that the UV lamp only operates when the door is closed, thus preventing accidental injury to the user.
[0003] Meanwhile, the inner liner is mostly rectangular, requiring multiple sheet metal sheets to be connected and fixed together during the inner liner molding process. For example, Chinese patent CN202120585056.3 discloses a sheet metal sheet assembly and connection structure for a disinfection cabinet inner liner, which includes a peripheral wall and a back panel connected to the rear side of the peripheral wall. To ensure the stability of the connection between the peripheral wall and the back panel, most manufacturers use a first flange extending radially outward on the back panel and a second flange extending radially outward and fixedly connected to the first flange on the peripheral wall. The large mating area between the first and second flanges achieves a stable connection between the peripheral wall and the back panel. However, considering the molding process and manufacturing cost of the inner liner, the inner liner is usually quite thin, typically between 0.4mm and 1mm. Therefore, the ends of the first and second flanges are relatively sharp. Typically, the control board, which is electrically connected to the micro switch, is fixed on the back panel, while the micro switch is located at the front of the inner liner. When the wiring harness connecting the micro switch and the control board passes through the first and second flanges, it will come into contact with them. When the user moves the disinfection cabinet, the wiring harness will shake. Prolonged shaking will cause significant wear and tear on the first and second flanges, and may even expose the metal wires inside the wiring harness, causing a short circuit. This can lead to the micro switch becoming insensitive or even malfunctioning, ultimately compromising the safety of the disinfection cabinet and seriously affecting the user experience. Utility Model Content
[0004] The purpose of this utility model is to provide a safe disinfection cabinet to solve the problem of how to optimize the wiring between the micro switch and the control board in existing disinfection cabinets, under the premise of adding micro switches to ensure disinfection safety, so as to avoid the micro switch failure caused by the wire harness breaking and short circuit due to long-term friction with the flange.
[0005] To achieve the above objectives, this utility model provides a safe disinfection cabinet, including a cabinet body and a cabinet door. One end of the cabinet door is hinged to the cabinet body, and the other end is a free end for opening or closing the cabinet door. The cabinet body includes a mating end that cooperates with the free end of the cabinet door, and a micro switch is provided at the mating end. The cabinet body also includes an inner liner with a front opening and an outer shell covering the outside of the inner liner. The top wall of the inner liner has a protrusion, and the back panel of the inner liner has a first flange extending radially outward. The peripheral wall of the inner liner has a second flange extending radially outward and fixedly connected to the first flange. The height of the protrusion is not less than the height of the first flange and the second flange. A control board is fixed to the back panel, and a buckle is provided on the protrusion. The wiring harness of the micro switch is snapped into the buckle and passes through the protrusion to connect with the control board.
[0006] This application incorporates a microswitch at the cabinet's mating end. When using the disinfection cabinet for sterilization, the microswitch is only triggered after the cabinet door is completely closed, thus activating the sterilization function. Simultaneously, if the user opens the cabinet door, the microswitch detects that the door is not fully closed, stopping the disinfection cabinet's operation, particularly halting the UV lamp's operation, ensuring safety during use. Furthermore, the inner liner's back panel has a first flange extending radially outward, and the inner liner's peripheral wall has a second flange extending radially outward and fixedly connected to the first flange. This allows the first and second flanges to expand the contact area between the back panel and the peripheral wall, improving the stability of the connection and preventing loosening due to the high temperature and pressure generated during sterilization.
[0007] Furthermore, the height of the protrusion is not lower than the height of the first and second flanges. A control board is fixed to the back plate, and a buckle is provided on the protrusion. The wiring harness of the micro switch is snapped into the buckle and passes over the protrusion to connect with the control board. On the one hand, the pre-fixing of the wiring harness by the buckle can control the wiring path, ensuring that the wiring harness can only connect to the control board after passing over the protrusion. During the process of the wiring harness passing over the protrusion, since the height of the protrusion is not lower than the height of the first and second flanges, the protrusion has a certain lifting effect on the wiring harness. After the wiring harness separates from the protrusion, it can pass over the first and second flanges, thus allowing the wiring harness to avoid the first and second flanges during the wiring process, thereby effectively preventing the wiring harness from being damaged by the first flanges. Prolonged use can cause severe wear to the wire harness due to contact with the relatively sharp first and second flanges, resulting in exposed metal wires and short circuits. This can lead to unstable or even malfunctioning microswitches. Reducing wire harness wear ensures stable operation of the microswitch. On the other hand, the snap-fit mechanism limits the wire harness's position, ensuring stability and preventing it from wobbling due to unstable positioning, which could cause severe wear and short circuits. This further protects the wire harness, ensuring the stability of the microswitch and ultimately the safety of the entire device.
[0008] In a preferred embodiment of a safe disinfection cabinet, the back panel is also fixed with an air supply component and an air-concentrating hood covering the air supply component. The air-concentrating hood is located on one side of the control panel, and the wiring harness passes through the air-concentrating hood and is connected to the control panel.
[0009] By fixing an air supply component and a concentrator covering the air supply component to the back panel, the user can guide hot air into the inner chamber through the air supply component to achieve high-temperature sterilization and drying of the appliances when using the disinfection cabinet. At the same time, the concentrator can concentrate the hot air into the inner chamber, improving sterilization efficiency. Moreover, the wiring harness passes through the concentrator and connects to the control board. On the one hand, after the wiring harness passes through the concentrator, it can limit the position of the wiring harness, thereby ensuring the stability of the wiring harness position, further preventing wear caused by its shaking, and further enhancing the protection of the wiring harness. On the other hand, when the air supply component is working, it can cool the wiring harness, ensuring that the wiring harness will not age severely due to excessive temperature in high-temperature environments, which helps to extend the service life of the wiring harness.
[0010] In a preferred embodiment of a safe disinfection cabinet, the top wall of the air hood is provided with a first clearance opening, and the side wall of the air hood facing the control panel is provided with a second clearance opening. The wiring harness passes through the first clearance opening and the second clearance opening in sequence and then connects to the control panel.
[0011] By providing a first clearance opening on the top wall of the wind-concentrating shroud and a second clearance opening on the side wall of the wind-concentrating shroud facing the control board, and by having the wire harness pass through the first and second clearance openings in sequence before connecting to the control board, the wire harness, after passing over the protrusion, first enters the wind-concentrating shroud through the first clearance opening and then exits the wind-concentrating shroud through the second clearance opening to connect to the control board. The first and second clearance openings provide a dual limiting effect for the wire harness, further ensuring the positional stability of the wire harness. At the same time, the second clearance opening is located close to the control board, which ensures the stability of the connection between the wire harness and the control board, thereby ensuring the connection stability between the wire harness and the control board and preventing the connection between the wire harness and the control board from being broken due to prolonged shaking.
[0012] In a preferred embodiment of a safe disinfection cabinet, the top wall of the inner liner is provided with an ultraviolet lamp plate, which includes a lamp panel with ultraviolet lamps and a cover covering the outside of the ultraviolet lamp panel. The cover protrudes from the top wall of the inner liner, and the protrusion is the cover.
[0013] By incorporating a UV lamp panel on the top wall of the inner liner, which includes a lamp plate housing UV lamps and a cover over the lamp plate, the disinfection cabinet effectively kills bacteria by emitting UV light through the lamp plate during operation. Simultaneously, the cover protects the lamp plate from moisture and damage. Furthermore, the protrusion serves as the cover, adding another functional element. This dual-purpose design eliminates the need for additional components within the inner liner to create the protrusion, simplifying the overall structure, improving compactness, and reducing vertical dimensions, thus minimizing the space occupied by the entire unit.
[0014] In a preferred embodiment of a safe disinfection cabinet, the cover is provided with a wiring hole, the wiring harness of the lamp board extends out of the cover from the wiring hole and is engaged with the wiring harness of the micro switch in a buckle, and is electrically connected to the control board.
[0015] The wiring harness of the lamp board extends out of the cover through the wire outlet and is locked together with the wiring harness of the micro switch in a buckle. It is also electrically connected to the control board, so that the wiring harness of the lamp board and the wiring harness of the micro switch can be limited by the buckle, ensuring the stability of their positions. At the same time, it can also ensure the neatness of the wiring harness inside the machine, avoid interference between the wiring harness and other components, and improve the safety of the overall machine structure.
[0016] In a preferred embodiment of a safe disinfection cabinet, a support beam is provided above the protrusion, the support beam extends from the mating end toward the back panel, and the wiring harness passes between the support beam and the protrusion.
[0017] By providing a support beam above the protrusion, extending from the mating end towards the back plate, the inner liner is supported and protected. When the outer shell is impacted and deforms inward, the support beam effectively disperses and absorbs the impact force, protecting the inner liner from damage. Simultaneously, the wiring harness passes between the support beam and the protrusion. When the outer shell is impacted and deforms inward, it directly abuts against the support beam. The support beam prevents the outer shell from colliding with the wiring harness, thus protecting it and effectively avoiding potential damage from impact forces. Preferably, a small gap passage is provided between the support beam and the protrusion, through which the wiring harness passes, preventing it from passing above the support beam and adhering to the top wall of the outer shell, thus avoiding direct collision between the outer shell and the wiring harness.
[0018] In a preferred embodiment of a safe disinfection cabinet, the inner liner has an outwardly extending third flange at its opening, the outer shell has a surrounding panel fixedly connected to the third flange, the cabinet body also has a decorative panel covering the outside of the surrounding panel, a micro switch is detachably mounted on the surrounding panel, and the decorative panel has a clearance hole for the micro switch's contact rod to extend out.
[0019] By incorporating a third, outwardly extending flange at the opening of the inner liner, and a surrounding plate fixedly connected to the third flange on the outer shell, the outer shell is securely connected to the inner liner via the surrounding plate while ensuring the third flange remains concealed, thus maintaining the overall structural integrity. The cabinet also features a decorative panel covering the outside of the surrounding plate, concealing it and preventing the connecting components between the surrounding plate and the third flange from being exposed, enhancing the product's aesthetics. Furthermore, the decorative panel includes a clearance hole for the microswitch's contact rod to extend from, ensuring that the contact rod can be activated after the cabinet door is closed, thus enabling door closure detection. The clearance hole also guides and positions the contact rod, ensuring its movement is confined to the clearance hole and guaranteeing stable triggering.
[0020] In a preferred embodiment of a safe disinfection cabinet, a guide tube extending toward the back panel is provided at the clearance hole, and the guide tube surrounds the outside of the contact rod.
[0021] By providing a guide cylinder extending towards the back plate at the clearance hole, and surrounding the outside of the contact rod, the guide cylinder further guides and positions the contact rod, ensuring the stability of the contact rod's position. At the same time, it also positions the entire micro switch, ensuring that the micro switch is in a stable and effective position, thereby improving the sensitivity of the micro switch detection.
[0022] In a preferred embodiment of a safe disinfection cabinet, the enclosure is provided with mounting holes for fixing micro switches. The side of the mounting holes near the back panel is provided with a limiting step with a reduced inner diameter. The micro switch includes a body, a limiting plate extending radially outward from the body, and an elastic buckle located at the tail of the body. The limiting plate abuts against the limiting surface of the limiting step, and the elastic buckle is engaged with the side wall of the limiting step.
[0023] By configuring the micro switch as including a body, a limiting plate extending radially outward from the body, and an elastic buckle located at the tail of the body, with the limiting plate abutting against the limiting surface of the limiting step and the elastic buckle engaging with the side wall of the limiting step, the micro switch can achieve axial limiting through the limiting plate and the limiting surface, and radial limiting through the limiting hole. Furthermore, it can achieve further radial limiting through the elastic buckle and the side wall of the limiting step. This significantly improves the positional stability of the micro switch, ensuring its detection accuracy and preventing displacement of the micro switch due to collisions with the disinfection cabinet caused by misoperation, thus preventing insensitive detection and further enhancing the overall safety of the machine.
[0024] In a preferred embodiment of a safe disinfection cabinet, the opening of the inner liner is provided with an outwardly extending third flange, on which a support frame is fixed, and the support frame is provided with a clearance portion that avoids the elastic buckle of the micro switch.
[0025] By incorporating a third, outwardly extending flange at the opening of the inner liner, with a support frame fixed to it, the third flange is reinforced, ensuring its strength and stability. This guarantees that the third flange maintains structural integrity even under significant impact, thereby enhancing the overall structural strength of the machine. Simultaneously, the support frame features a clearance portion that avoids interference with the microswitch's elastic latch. This clearance portion not only prevents interference but also limits the position of the microswitch's elastic latch, thus ensuring its stability and preventing displacement due to collisions with the disinfection cabinet, which could lead to insensitive detection by the microswitch.

Detailed Implementation
[0036] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0037] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0038] like Figures 1 to 7As shown, this utility model provides a safe disinfection cabinet, including a cabinet body 1 and a cabinet door 2. One end of the cabinet door 2 is hinged to the cabinet body 1, and the other end is a free end 21 to open or close the cabinet door 2. The cabinet body 1 includes a mating end 11 that cooperates with the free end 21 of the cabinet door 2. A micro switch 5 is provided at the mating end 11. The cabinet body 1 also includes an inner liner 12 with a front opening and an outer shell covering the outside of the inner liner 12. The top wall of the inner liner 12 is provided with a protrusion 3. The back plate 121 of the inner liner 12 is provided with a first flange 1211 extending radially outward. The peripheral wall 122 of the inner liner 12 is provided with a second flange 1221 extending radially outward and fixedly connected to the first flange 1211. The height of the protrusion 3 is not less than the height of the first flange 1211 and the second flange 1221. A control plate 7 is fixed to the back plate 121. A buckle 31 is provided on the protrusion 3. The wiring harness 6 of the micro switch 5 is snapped into the buckle 31 and passes through the protrusion 3 to connect with the control plate 7.
[0039] This application incorporates a microswitch 5 at the mating end 11 of the cabinet 1. This ensures that when the user disinfects utensils, the microswitch 5 is only triggered after the cabinet door 2 is completely closed, thus activating the disinfection function. Simultaneously, if the user opens the cabinet door 2, the microswitch 5 detects that the door is not fully closed, thereby stopping the disinfection cabinet's operation, particularly stopping the ultraviolet lamp, ensuring safety during use. Furthermore, the back panel 121 of the inner liner 12 has a radially outward-extending first flange 1211, and the peripheral wall 122 of the inner liner 12 has a radially outward-extending second flange 1221 fixedly connected to the first flange 1211. This allows the first flange 1211 and the peripheral wall 122 to expand their contact area when connected, thereby improving the stability of the connection and preventing loosening due to the high temperature and pressure generated during disinfection.
[0040] Furthermore, the height of the protrusion 3 is not lower than the height of the first flange 1211 and the second flange 1221, and more preferably, such as Figure 2As shown, the height of the protrusion 3 is higher than the height of the first flange 1211 and the second flange 1221. The back plate 121 is fixed with a control plate 7. A buckle 31 is provided on the protrusion 3. The wiring harness 6 of the micro switch 5 is snapped into the buckle 31 and passes over the protrusion 3 to connect with the control plate 7. On the one hand, the wiring harness 6 can only connect to the control plate 7 after passing over the protrusion 3. During the process of the wiring harness 6 passing over the protrusion 3, since the height of the protrusion 3 is not lower than the height of the first flange 1211 and the second flange 1221, the protrusion 3 has a certain lifting effect on the wiring harness 6. After the wiring harness 6 separates from the protrusion 3, it can pass over the first flange 1211 and the second flange 1221, so that the wiring harness 6 avoids the first flange 1211 and the second flange 1221 during the wiring process. This effectively prevents the wire harness 6 from coming into contact with the relatively sharp first flange 1211 and second flange 1221 due to prolonged use, which could cause severe wear to the wire harness 6, resulting in exposed metal wires inside the wire harness 6 and short circuits. This could lead to unstable operation or even failure of the micro switch 5, thus reducing wear on the wire harness 6 and ensuring stable operation of the micro switch 5. On the other hand, after the wire harness 6 is engaged by the clip 31, it can achieve a limiting effect on the wire harness 6, ensuring the stability of the wire harness 6's position. This prevents the wire harness 6 from being able to shake freely due to unstable limiting, which could cause severe wear and short circuits. This further protects the wire harness 6, ensures the stability of the micro switch 5's operation, and ultimately ensures the safety of the entire machine.
[0041] As a preferred embodiment of this application, such as Figure 2 As shown, the back panel 121 is also fixed with an air supply assembly and an air-concentrating hood 8 covering the air supply assembly. The air-concentrating hood 8 is located on one side of the control panel 7, and the wiring harness 6 passes through the air-concentrating hood 8 and is connected to the control panel 7.
[0042] By fixing an air supply component and a concentrator 8 covering the air supply component to the back panel 121, the user can guide hot air into the inner liner 12 through the air supply component to achieve high-temperature sterilization and drying of the appliance when using the disinfection cabinet. At the same time, the concentrator 8 can concentrate the hot air and guide it into the inner liner 12, improving the sterilization efficiency. Moreover, the wiring harness 6 passes through the concentrator 8 and connects to the control board 7. On the one hand, after the wiring harness 6 passes through the concentrator 8, the concentrator 8 can limit the position of the wiring harness 6, thereby further ensuring the stability of the position of the wiring harness 6, further preventing wear caused by its shaking, and further enhancing the protection of the wiring harness 6. On the other hand, when the air supply component is working, it can cool the wiring harness 6, ensuring that the wiring harness 6 will not age severely due to excessive temperature in high-temperature environments, which helps to extend the service life of the wiring harness 6.
[0043] Furthermore, such as Figure 2As shown, the top wall of the wind concentrator 8 is provided with a first clearance opening 81, and the side wall of the wind concentrator 8 facing the control board 7 is provided with a second clearance opening 82. The wire harness 6 passes through the first clearance opening 81 and the second clearance opening 82 in sequence and then connects to the control board 7.
[0044] By providing a first clearance opening 81 on the top wall of the wind concentrator 8 and a second clearance opening 82 on the side wall of the wind concentrator 8 facing the control board 7, and by having the wire harness 6 pass through the first clearance opening 81 and the second clearance opening 82 in sequence before connecting to the control board 7, the wire harness 6, after passing over the protrusion 3, first enters the wind concentrator 8 through the first clearance opening 81, and then exits the wind concentrator 8 through the second clearance opening 82 and connects to the control board 7. The first clearance opening 81 and the second clearance opening 82 achieve a dual limiting effect on the wire harness 6, further ensuring the positional stability of the wire harness 6. At the same time, the second clearance opening 82 is set close to the control board 7, which can ensure the stability of the connection between the wire harness 6 and the control board 7, thereby ensuring the connection stability between the wire harness 6 and the control board 7 and preventing the wire harness 6 from being disconnected due to prolonged shaking.
[0045] It should be noted that this application does not specifically limit the forming of the protrusion 3. It can be formed by the protrusion 3 being raised upward on the top wall of the inner liner 12. Alternatively, as a preferred embodiment of this application, the top wall of the inner liner 12 is provided with an ultraviolet lamp plate, which includes a lamp plate with ultraviolet lamps and a cover covering the outside of the ultraviolet lamp plate. The cover protrudes from the top wall of the inner liner 12, and the protrusion 3 is the cover.
[0046] By incorporating a UV lamp panel on the top wall of the inner liner 12, which includes a lamp plate with UV lamps and a cover over the lamp plate, the disinfection cabinet can effectively kill bacteria by emitting UV light through the lamp plate during operation. Simultaneously, the cover protects the lamp plate from moisture or damage. Furthermore, the protrusion 3 serves as the cover, providing an additional functional purpose. This dual-purpose design eliminates the need for additional components on the inner liner 12 to form the protrusion 3, simplifying the overall structure, improving structural compactness, and reducing vertical dimensions, thus minimizing the overall space occupied by the machine.
[0047] Furthermore, such as Figure 2 As shown, the cover has a wire outlet hole. The wiring harness of the lamp board extends out of the cover from the wire outlet hole and is locked together with the wiring harness 6 of the micro switch 5 in the buckle 31, and is electrically connected to the control board 7.
[0048] The wiring harness of the lamp board extends out of the cover through the wire outlet and is locked together with the wiring harness 6 of the micro switch 5 in the buckle 31. It is also electrically connected to the control board 7. This allows both the wiring harness of the lamp board and the wiring harness 6 of the micro switch 5 to be limited by the buckle 31, ensuring the stability of their positions. At the same time, it also ensures the neatness of the wiring harness 6 inside the machine, avoids interference between the wiring harness 6 and other components, and improves the safety of the overall machine structure.
[0049] As a preferred embodiment of this application, such as Figure 2 As shown, a support beam 4 is also provided above the protrusion 3. The support beam 4 extends from the mating end 11 to the back plate 121, and the wire harness 6 passes between the support beam 4 and the protrusion 3.
[0050] By providing a support beam 4 above the protrusion 3, and extending the support beam 4 from the mating end 11 towards the back plate 121, the inner liner 12 is supported and protected. When the outer shell is impacted and deforms inward, the support beam 4 effectively disperses and absorbs the impact force, protecting the inner liner 12 from damage. Simultaneously, the wiring harness 6 passes between the support beam 4 and the protrusion 3. When the outer shell is impacted and deforms inward, the outer shell directly abuts against the support beam 4. The support beam 4 prevents the outer shell from colliding with the wiring harness 6, thus protecting the wiring harness 6 and effectively avoiding potential damage from impact forces. Preferably, a small gap passage is provided between the support beam 4 and the protrusion 3, through which the wiring harness 6 passes. This prevents the wiring harness 6 from passing above the support beam 4 and adhering to the top wall of the outer shell, thus avoiding direct collision between the outer shell and the wiring harness 6.
[0051] As a preferred embodiment of this application, such as Figure 3 , Figure 4 , Figure 7 As shown, the inner liner 12 has an outwardly extending third flange 123 at the opening, the outer shell has a surrounding plate 13 fixedly connected to the third flange 123, the cabinet 1 also has a decorative plate 9 covering the outside of the surrounding plate 13, the micro switch 5 is detachably mounted on the surrounding plate 13, and the decorative plate 9 has a clearance hole 91 for the contact rod of the micro switch 5 to extend out.
[0052] By providing an outwardly extending third flange 123 at the opening of the inner liner 12, and a surrounding plate 13 fixedly connected to the third flange 123 on the outer shell, the outer shell is fixedly connected to the inner liner 12 through the surrounding plate 13, while ensuring that the third flange 123 is not exposed, thus maintaining the integrity of the overall structure. Simultaneously, the cabinet 1 also has a decorative plate 9 covering the outside of the surrounding plate 13, thus concealing the surrounding plate 13 and preventing the connecting parts of the surrounding plate 13 and the third flange 123 from being exposed, enhancing the aesthetics of the product. The decorative plate 9 also has a clearance hole 91 for the extension of the contact rod of the micro switch 5, allowing the contact rod to extend from the clearance hole 91, ensuring that the contact rod can be touched after the cabinet door 2 is closed, achieving the closure detection of the disinfection cabinet door 2. Furthermore, the clearance hole 91 guides and positions the contact rod, ensuring that the contact rod can only move within the clearance hole 91, thereby ensuring the stability of the contact rod triggering.
[0053] Furthermore, such as Figure 4 As shown, a guide cylinder 92 extending toward the back plate 121 is provided at the clearance hole 91, and the guide cylinder 92 surrounds the outside of the contact rod.
[0054] By providing a guide cylinder 92 extending toward the back plate 121 at the clearance hole 91, and the guide cylinder 92 surrounding the outside of the contact rod, the guide and positioning of the contact rod is further realized, ensuring the stability of the contact rod position. At the same time, it can also realize the positioning function of the entire micro switch 5, ensuring that the position of the micro switch 5 is stable and effective, thereby improving the sensitivity of the micro switch 5 detection.
[0055] As a preferred embodiment, such as Figure 4 As shown, the enclosure 13 is provided with mounting holes 131 for fixing micro switch 5. The mounting hole 131 is provided with a limiting step 132 with a reduced inner diameter on the side near the back plate 121. The micro switch 5 includes a body 51, a limiting plate 52 extending radially outward from the body 51, and an elastic buckle 53 located at the tail of the body 51. The limiting plate 52 abuts against the limiting surface of the limiting step 132, and the elastic buckle 53 is engaged with the side wall of the limiting step 132.
[0056] By configuring the micro switch 5 to include a body 51, a limiting plate 52 extending radially outward from the body 51, and an elastic buckle 53 located at the tail of the body 51, with the limiting plate 52 abutting against the limiting surface of the limiting step 132 and the elastic buckle 53 engaging with the side wall of the limiting step 132, the micro switch 5 can achieve axial limiting through the limiting plate 52 and the limiting surface, and radial limiting through the limiting hole. On the other hand, it can also achieve further radial limiting through the elastic buckle 53 and the side wall of the limiting step 132. This greatly improves the positional stability of the micro switch 5, thereby ensuring its detection accuracy and preventing the micro switch 5 from shifting due to collisions caused by misoperation of the disinfection cabinet, which could lead to insensitive detection by the micro switch 5. This further enhances the safety of the entire machine.
[0057] As a preferred embodiment of this application, such as Figure 5 , Figure 6 , Figure 7 As shown, the opening of the inner liner 12 is provided with an outwardly extending third flange 123, and a support frame 10 is fixed on the flange. The support frame 10 is provided with a clearance part 101 that avoids the elastic buckle 53 of the micro switch 5. Preferably, as shown in the figure, Figure 6 As shown, the clearance portion 101 is a clearance notch provided on the side facing the elastic buckle 53.
[0058] By providing an outwardly extending third flange 123 at the opening of the inner liner 12, and fixing a support frame 10 on the third flange 123, the third flange 123 can be reinforced with the support frame 10, ensuring the strength and stability of the third flange 123, and ensuring that it can maintain the integrity of the structure when subjected to a large impact, thereby improving the structural strength of the whole machine. At the same time, the support frame 10 is provided with a clearance part 101 to avoid interference between the micro switch 5 and the elastic buckle 53 of the micro switch 5. This allows the support frame 10 to not only avoid interference between the micro switch 5 and the micro switch 5, but also to limit the position of the elastic buckle 53 of the micro switch 5 through the clearance part 101, thereby limiting the position of the entire micro switch 5, ensuring its positional stability, and preventing the micro switch 5 from shifting due to collisions with the disinfection cabinet, which could lead to the micro switch 5 becoming insensitive.
