Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a disinfection inner liner and a disinfection cabinet containing the same. Background Technology

[0002] Currently, most disinfection cabinets use ultraviolet (UV) disinfection. During assembly, the UV lamp plate needs to be installed on the side of the inner liner away from the cavity, and the inner liner has openings for the UV lamp beads to pass through.

[0003] In related technologies, to improve the protection of the LED beads, the beads are usually required not to protrude from the opening during installation. However, the opening wall can block the light diffusion of the LED beads, affecting the sterilization effect. At the same time, for better sterilization, multiple spaced LED beads are usually set on the lamp plate, with each LED bead corresponding to one opening. This makes it easier for moisture inside the chamber to seep into the lamp plate through multiple openings, causing the LED beads to be easily damaged. Utility Model Content

[0004] Therefore, it is necessary to provide a sterilization inner liner that, on the one hand, reduces the obstruction of the LED beads and ensures that the light from the LED beads is fully diffused into the liner cavity, thereby improving the sterilization effect; on the other hand, it enhances the sealing of the assembly holes to prevent moisture and other substances from entering the liner cavity, improves the protection of the LED panel assembly, and facilitates the arrangement of multiple LED beads.

[0005] A disinfection liner includes an inner liner body, a fixing bracket, and a lamp plate assembly. The inner liner body has a through mounting hole. The fixing bracket is fixed to the outside of the inner liner body. The lamp plate assembly includes a lamp plate and lamp beads disposed on the lamp plate. The lamp plate is limited and connected between the fixing bracket or the fixing bracket and the inner liner body, and the lamp beads are accommodated in the mounting hole. The mounting hole has a gradually expanding section extending from the outside of the inner liner body towards the inside of the inner liner body, and a pressing section connected to the minimum diameter of the gradually expanding section. The pressing section extends axially along the mounting hole. The disinfection liner also includes a sealing structure, which is pressed between the pressing section and the lamp plate, and the sealing structure is sleeved on the end of the lamp beads near the lamp plate.

[0006] Understandably, the use of the gradually expanding section in the assembly hole serves two purposes: firstly, it better matches the light dispersion direction of the LED beads, facilitating light diffusion; secondly, it effectively increases the size of the assembly hole within the inner liner, reducing the area obstructed by the LED beads and allowing the light from the beads to diffuse as fully as possible into the liner cavity. This reduces diffusion dead zones, ensuring that the ultraviolet light emitted by the LED beads diffuses as widely as possible throughout the liner cavity, improving sterilization efficiency. Furthermore, the pressing section works in conjunction with the lamp plate to achieve a sealed assembly, enhancing the sealing at the assembly hole and preventing moisture from entering the side of the assembly hole away from the liner cavity, thus improving the protection of the lamp plate assembly. Moreover, the axial extension of the pressing section improves the structural strength and reliability of the sealing structure at the assembly hole, while maintaining a small footprint within the inner liner body at the maximum diameter of the gradually expanding section of a single assembly hole. This allows for the spaced arrangement of multiple assembly holes and LED beads, further enhancing the sterilization effect.

[0007] In some embodiments, the inner liner body has a liner wall portion, the assembly hole is recessed from the inside out in the liner wall portion, and the angle α between the hole wall of the gradually expanding section and the liner wall portion is between 110° and 170°.

[0008] This design not only reduces the obstruction of light from the LED beads, but also ensures that the largest diameter of the assembly hole does not occupy a large space in the inner wall, which is conducive to arranging multiple LED beads and thus improving the sterilization effect.

[0009] In some embodiments, the angle α between the pore wall of the expanding section and the gallbladder wall is between 120° and 160°.

[0010] In this way, while increasing the inclination angle of the hole wall, the space occupied by the gallbladder wall is reduced, thereby ensuring that when multiple lamp beads are used together, the light from each lamp bead can be diffused into the gallbladder cavity as fully as possible.

[0011] In some embodiments, the lamp bead includes a columnar portion and a spherical portion connected to the columnar portion, the columnar portion being connected to the lamp plate, and the sealing structure being sleeved on the columnar portion; along the axial direction of the mounting hole, the sealing structure does not protrude from the end of the columnar portion away from the lamp plate.

[0012] This design maintains good sealing at the LED chip while reducing the interference of the sealing structure on the light diffusion of the LED chip.

[0013] In some embodiments, along the axial direction of the mounting hole, the dimension H2 of the expanding section is larger than the dimension of the pressing section H1.

[0014] In this way, while maintaining a consistent mounting hole depth, the size of the expanding section is kept large, so that the part of the lamp bead used for light diffusion is located within the expanding section as much as possible, which significantly reduces the light blockage of the lamp bead.

[0015] In some embodiments, along the axial direction of the mounting hole, the dimension H1 of the press-fit section accounts for 10%-35% of the dimension H2 of the expanding section.

[0016] In other words, by limiting the size of the pressing section relative to the gradually expanding section, not only is the light obstruction reduced, but the reliable pressing of the sealing structure is also ensured.

[0017] In some embodiments, the lamp beads are provided in a plurality of spaced-apart arrangement on the lamp board, and each lamp bead corresponds to one mounting hole;

[0018] Each of the LED beads is fitted with a sealing ring near the lamp board, and the sealing ring is pressed between the outer end of the corresponding assembly hole and the lamp board; or, the disinfection liner also includes a sealing gasket pressed between the lamp board and the outer end of each of the assembly holes, the sealing gasket having a plurality of spaced sealing holes, and each LED bead passing through one of the sealing holes and sealingly fitting.

[0019] This setup not only utilizes multiple LED beads to work together to improve the sterilization effect, but also ensures good sealing at each LED bead assembly point, extending its service life.

[0020] In some embodiments, the lamp panel is snapped onto the fixed bracket. This facilitates the assembly and disassembly of the lamp panel assembly relative to the fixed bracket, thereby aiding in replacement and maintenance.

[0021] In some embodiments, the inner liner body is made of stainless steel to improve the safety of using the sterilization inner liner.

[0022] This application also provides a disinfection cabinet, including the aforementioned disinfection inner liner, a cabinet body surrounding the outside of the disinfection inner liner, and a cabinet door movably connected to the cabinet body. Attached Figure Description

The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0037] In related technologies, to improve the protection of UV lamps, they are typically installed on the outside of the inner liner, and the lamp beads do not protrude from the openings in the inner liner to achieve concealed assembly. For ease of production, the openings are mostly flat, meaning the cross-sectional area is the same at all points along the opening's axis. However, precisely because the lamp beads do not protrude from the openings, the flat-hole design significantly obstructs the light from the lamp beads, preventing some light from diffusing into the inner liner cavity and affecting the sterilization effect. Furthermore, to enhance the sterilization effect, multiple lamp beads are usually installed inside the inner liner, each corresponding to an opening. This makes it easier for moisture inside the liner cavity to seep into the lamp plate through these openings, leading to increased vulnerability of the lamp beads and lamp plate.

[0038] In response to this, one embodiment of this application provides a sterilization inner liner that, on the one hand, can effectively reduce the obstruction of light diffusion from the LED beads, ensuring that the light from the LED beads diffuses into the liner cavity as fully as possible, reducing diffusion dead zones, and thus improving the sterilization effect; on the other hand, it enhances the sealing of the assembly holes, preventing moisture and other substances from entering the liner cavity, improving the protection of the LED panel assembly, and facilitating the arrangement of multiple LED beads.

[0039] Please see Figures 1 to 5For example, the disinfection inner liner 100 includes an inner liner body 110, a fixing bracket 120, and a lamp panel assembly 130. The inner liner body 110 has a through mounting hole 111. The fixing bracket 120 is fixed to the outside of the inner liner body 110. The lamp panel assembly 130 includes a lamp panel 131 and lamp beads 132 disposed on the lamp panel 131. The lamp panel 131 is limitedly connected to the fixing bracket 120 or limitedly connected between the fixing bracket 120 and the inner liner body 110. The lamp beads 132 are accommodated in the mounting hole 111. The mounting hole 111 has a gradually expanding section 1111 that gradually widens from the outside of the inner liner body 110 to the inside of the inner liner body 110, and a pressing section 1112 connected at the minimum diameter of the gradually expanding section 1111. The pressing section 1112 extends axially along the mounting hole 111. The disinfection inner liner 100 also includes a sealing structure 140, which is pressed between the pressing section 1112 and the lamp plate 131, and is sleeved on one end of the lamp bead 132 near the lamp plate 131.

[0040] It should be noted in advance that the inner liner body 110 is surrounded by a cavity 1101 for storing the items to be disinfected. The inner side of the inner liner body 110 faces the cavity 1101, and the outer side of the inner liner body 110 faces away from the cavity 1101. Therefore, the expanding section 1111 extends gradually from the outside to the inside.

[0041] Understandably, both the lamp panel assembly 130 and the fixing bracket 120 are located on the outside of the inner liner body 110. This not only facilitates the connection of the lamp panel assembly 130 to the power supply but also prevents collisions with the items being disinfected, thus improving safety. The lamp panel assembly 130 is fixed relative to the inner liner body 110 via the fixing bracket 120, improving the assembly reliability of the lamp panel assembly 130. When the lamp panel 131 is fixedly connected to the fixing bracket 120, the two can be connected as a single structure, and then disassembled and reassembled relative to the inner liner body 110 as a single unit. This makes the operation simpler, more convenient, and easier to assemble and position.

[0042] Based on this, the design of the gradually expanding section 1111 in the assembly hole 111 serves two purposes: firstly, it better matches the light dispersion direction of the LED bead 132, facilitating light diffusion; secondly, it effectively increases the size of the assembly hole 111 on the inner side of the inner liner body 110, reducing obstruction of the LED bead 132 and allowing the light from the LED bead 132 to diffuse as fully as possible into the liner cavity 1101. Furthermore, the gradually expanding section 1111 causes the wall of the assembly hole 111 located on the outer periphery of the LED bead 132 to be inclined, thus reflecting the light from the LED bead 132 and further enhancing the light diffusion effect within the inner liner body 110. In this way, the diffusion dead zone is reduced, allowing the light emitted by the LED bead 132 to diffuse as fully as possible throughout the liner cavity 1101, improving the sterilization effect.

[0043] Meanwhile, the pressing section 1112 in the assembly hole 111 can cooperate with the lamp plate 131 to meet the assembly of the sealing structure 140, thereby enhancing the sealing performance at the assembly hole 111 and preventing moisture and other substances in the chamber 1101 from entering the side of the assembly hole 111 away from the chamber 1101, thus improving the protection of the lamp plate assembly 130. Because the pressing section 1112 extends axially along the assembly hole 111, when it cooperates with the lamp plate 131 to press the sealing structure 140, the applied force is along the axial direction of the assembly hole 111, thereby reducing the component force in other directions. This not only improves the structural strength at the assembly hole 111 but also enhances the assembly stability and reliability of the sealing structure 140. Furthermore, because the axial extension of the pressing section 1112 does not occupy the radial space of the mounting hole 111, the minimum diameter of the expanding section 1111 does not need to be increased to accommodate the radially extending pressing section 1112. Consequently, the maximum diameter of the expanding section 1111 also does not need to be increased, reducing the space occupied by a single mounting hole 111 on the inner liner body 110. Thus, the inner liner body 110 has multiple spaced mounting holes 111, each corresponding to a lamp bead 132, thereby utilizing multiple lamp beads 132 in conjunction to improve the sterilization effect.

[0044] In other words, the assembly hole 111, through the cooperation of the expanding section 1111 and the pressing section 1112, reduces the light obstruction of the lamp beads 132, increases the irradiation range of a single lamp bead, and thus improves the sterilization effect. Furthermore, it also increases the structural strength at the assembly hole 111, facilitating its assembly with the lamp plate 131 and improving the reliability of the sealing structure 140. On the other hand, reducing the space occupied by a single assembly hole 111 on the inner liner body 110 allows for the spaced arrangement of multiple lamp beads 132 and multiple assembly holes 111, enabling the spacing between any two adjacent assembly holes 111 to be appropriately reduced. This not only ensures that there is almost no irradiation blank area between any two adjacent lamp beads 132, but also guarantees an irradiation overlap area between any two adjacent lamp beads 132, further improving the sterilization effect.

[0045] In actual use, the sealing structure 140 is provided with a sealing hole 1401 for the lamp bead 132 to pass through, and the hole wall of the sealing hole 1401 is tightly fitted to the outer periphery of the lamp bead 132 to achieve a sealing effect.

[0046] The lamp bead 132 emits ultraviolet light for sterilization. The lamp bead 132 includes a columnar portion 1321 and a spherical portion 1322 connected to the columnar portion 1321. The columnar portion 1321 is connected to the lamp panel 131. The spherical portion 1322 is mainly used for light diffusion, and a gradually expanding section 1111 can be disposed at least around the outer periphery of the spherical portion 1322 to reduce obstruction of the lamp bead 132. A sealing structure 140 is fitted onto the columnar portion 1321 of the lamp bead 132 through a sealing hole 1401, further reducing obstruction of the spherical portion 1322.

[0047] Please see Figures 1 to 5 In some embodiments, the inner liner body 110 has a liner wall portion 112, and an assembly hole 111 is recessed from the inside to the outside of the liner wall portion 112. For example, the assembly hole 111, which is recessed from the inside to the outside of the liner wall portion 112, can be formed on the liner wall portion 112 by stamping, and the gradually expanding section 1111 is formed by the liner wall portion 112 gradually expanding from the outside to the inside.

[0048] The angle α between the orifice wall of the gradually expanding section 1111 and the gallbladder wall portion 112 is between 110° and 170°. Since the gradually expanding section 1111 is arranged to gradually expand from the outside to the inside, it is equivalent to the angle between the orifice wall of the gradually expanding section 1111 and the gallbladder wall portion 112 being an obtuse angle.

[0049] Understandably, the larger the angle between the wall of the expanding section 1111 and the inner wall 112, the larger the cross-sectional area at the maximum diameter of the mounting hole 111 becomes while maintaining the depth of the mounting hole 111. This results in the mounting hole 111 occupying a larger space in the inner wall 112, which is not conducive to the arrangement of multiple LED beads 132. Conversely, the smaller the angle between the wall of the expanding section 1111 and the inner wall 112, the smaller the cross-sectional area at the maximum diameter of the mounting hole 111 becomes while maintaining the depth of the mounting hole 111, resulting in insufficient mitigation of the obstruction of the LED beads 132.

[0050] Therefore, in this embodiment, the included angle between the hole wall of the gradually expanding section 1111 and the inner wall portion 112 is limited to between 110° and 170°. This ensures that the LED bead 132 does not protrude from the mounting hole 111, while reducing the obstruction of the LED bead 132 and maintaining the largest possible diffusion range. Furthermore, it ensures that the maximum diameter of the mounting hole 111 does not occupy a large space in the inner wall portion 112, facilitating the arrangement of multiple LED beads 132 and thus improving the sterilization effect. Each LED bead 132 corresponds to one mounting hole 111.

[0051] Furthermore, the angle α between the orifice wall of the expanding section 1111 and the inner wall portion 112 is between 120° and 160°. This ensures that the orifice wall inclination angle of the expanding section 1111 meets the irradiation requirements while further reducing the space occupied by a single assembly hole 111 on the inner wall portion 112. This results in a smaller spacing between any two adjacent LED beads 132. Given a consistent lamp plate size, more LED beads 132 can be arranged at intervals, significantly improving the sterilization effect. Moreover, this arrangement increases the irradiation overlap area between any two adjacent LED beads 132, facilitating more thorough and complete sterilization.

[0052] In some specific embodiments, the included angle α between the wall of the assembly hole 111 and the gallbladder wall portion 112 is 120°, 130°, 140°, 142°, 148°, 150°, 155° or 160°.

[0053] In actual use, multiple LED beads 132 can be arranged at intervals along the length of the lamp plate 131. By adjusting the spacing between any two adjacent LED beads 132 and the tilt angle of the gradually expanding section 1111 in the corresponding mounting hole 111 of each LED bead 132, the diffusion range between any two adjacent LED beads 132 can be made to overlap, thereby improving the sterilization effect.

[0054] In this configuration, the projection of the mounting hole 111 along its own axial direction is quadrilateral, and the expanding section 1111 is set in the shape of a frustum. The hole wall surrounding the lamp bead 132 is composed of four inclined surfaces. Alternatively, the projection of the mounting hole 111 along its own axial direction can also be circular, in which case the expanding section 1111 is set in the shape of a frustum, and the hole wall surrounding the lamp bead 132 is a conical surface.

[0055] Please combine Figure 3 and Figure 5 Furthermore, based on the sealing structure 140 being fitted onto the columnar portion 1321 of the lamp bead 132, along the axial direction of the mounting hole 111, the sealing structure 140 does not protrude from the end of the columnar portion 1321 away from the lamp plate 131; that is, the thickness H3 of the sealing structure 140 is not greater than the length H4 of the columnar portion 1321. The spherical portion 1322 is mainly used for light diffusion. Therefore, this arrangement ensures that the sealing structure 140 does not cover the spherical portion 1322, reducing interference of the sealing structure 140 with the light diffusion of the lamp bead 132 while maintaining good sealing at the lamp bead 132. In addition, because the sealing structure 140 does not protrude from the columnar portion 1321, the problem of aging of the sealing structure 140 due to long-term direct exposure to ultraviolet light emitted by the lamp bead 132 is alleviated, extending the service life of the sealing structure 140.

[0056] In this case, along the axial direction of the mounting hole 111, the thickness H3 of the sealing structure 140 is equal to the length H4 of the columnar portion 1321, that is, the side wall of the sealing structure 140 facing away from the lamp plate 131 is flush with the connection between the columnar portion 1321 and the spherical portion 1322. Alternatively, along the axial direction of the mounting hole 111, the thickness H3 of the sealing structure 140 is less than the length H4 of the columnar portion 1321.

[0057] It should be noted that the thickness of the sealing structure 140 should not be too small. If it is too small, the sealing area between the sealing structure 140 and the columnar part 1321 will be reduced, which will weaken the sealing effect.

[0058] The cross-section of the columnar portion 1321 can be circular, in which case the sealing hole 1401 on the sealing structure 140 is a circular hole. Alternatively, the cross-section of the columnar portion 1321 can be square, in which case the sealing hole 1401 on the sealing structure 140 is a square hole. The key requirement is that the sealing structure 140 can tightly wrap around the outer periphery of the columnar portion 1321 of the lamp bead 132 to achieve a seal; this is merely an example.

[0059] Please continue reading Figures 3 to 5 Furthermore, along the axial direction of the assembly hole 111, the dimension H2 of the expanding section 1111 is larger than the dimension H1 of the pressing section 1112. The expanding section 1111 is mainly used for light diffusion of the lamp bead 132, while the pressing section 1112 is used for stable assembly of the sealing structure 140.

[0060] Understandably, because the thickness of the sealing structure 140 should not be too small, the pressing section 1112 may occupy part of the spherical surface area 1322 if the sealing structure 140 does not protrude from the columnar portion 1321 of the lamp bead 132. Therefore, with the depth of the mounting hole 111 remaining unchanged, the size of the pressing section 1112 needs to be small, while maintaining the size of the expanding section 1111 needs to be large, so that the spherical surface area 1322 of the lamp bead 132 is located within the expanding section 1111 as much as possible. This significantly reduces the light obstruction to the lamp bead 132 while maintaining the stable assembly of the sealing structure 140.

[0061] For example, along the axial direction of the mounting hole 111, the dimension H1 of the pressing section 1112 accounts for 10%-35% of the dimension H2 of the expanding section 1111. That is, the dimension H1 of the pressing section 1112 should not be too large or too small. If it is too large, it will occupy a large axial dimension of the spherical surface 1322, which is not conducive to light diffusion; conversely, if it is too small, it will not be conducive to the reliable assembly of the sealing structure 140. Therefore, by limiting the dimension of the pressing section 1112 relative to the expanding section 1111, not only is light obstruction reduced, but the reliable assembly of the sealing structure 140 is also ensured. For example, along the axial direction of the mounting hole 111, the dimension H1 of the pressing section 1112 accounts for 10%, 15%, 20%, 30%, 33%, or 35% of the dimension H2 of the expanding section 1111.

[0062] like Figure 5 As shown, in some embodiments, the sum of the thickness H3 of the sealing structure 140 and the dimension H1 of the pressing section 1112 along the axial direction of the mounting hole 111 is not greater than the length H4 of the columnar portion 1321. This arrangement ensures that the spherical portion 1322 is completely located within the expanding section 1111, significantly reducing the obstruction of light diffusion of the lamp bead 132 while maintaining the sealing performance, thus promoting more sufficient light diffusion into the cavity.

[0063] Please see Figures 1 to 3 In some embodiments, multiple LED beads 132 are arranged at intervals on the lamp plate 131. Each LED bead 132 corresponds to a mounting hole 111, and each mounting hole 111 is gradually expanded from the outside to the inside to ensure that the light from each LED bead 132 can be fully diffused into the cavity 1101, reducing light obstruction for each LED bead 132. Simultaneously, the cooperation of multiple LED beads 132 can improve the sterilization effect. The lamp plate 131 is elongated, and the multiple LED beads 132 are arranged at intervals along the length of the lamp plate 131.

[0064] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 The aforementioned sealing structure 140 is a sealing gasket 141, which has multiple spaced-apart sealing holes 1401. Each LED bead 132 corresponds to one sealing hole 1401. The sealing gasket 141 is pressed between the outer end of each assembly hole 111 and the lamp board 131, and seals with each LED bead 132 through the sealing holes 1401. In other words, multiple LED beads 132 share one sealing gasket 141, satisfying the sealing requirements of each LED bead 132, making assembly more convenient. At this time, the sealing gasket 141 is also elongated, with multiple sealing holes 1401 spaced apart along the length of the sealing gasket 141.

[0065] Please see Figure 1 , Figure 2 , Figure 5 and Figure 7 In other embodiments, the sealing structure 140 can be a sealing ring 142. Each LED bead 132 is fitted with a sealing ring 142 near the lamp plate 131, and the sealing ring 142 is pressed between the outer end of the corresponding mounting hole 111 and the lamp plate 131. Specifically, the sealing ring 142 is fitted onto the columnar portion 1321 of the corresponding LED bead 132. That is, each LED bead 132 meets the sealing requirements through its corresponding sealing ring 142.

[0066] Please see Figure 2 , Figure 3 and Figure 7In some embodiments, the lamp panel 131 is snapped onto the fixed bracket 120. This arrangement facilitates the assembly and disassembly of the lamp panel assembly 130 relative to the fixed bracket 120, thereby aiding in replacement and maintenance. In actual assembly, after the lamp panel 131 is snapped onto and fixed relative to the fixed bracket 120, the lamp panel assembly 130 and the fixed bracket 120 are assembled as a whole relative to the inner liner body 110, making the operation simpler and more convenient.

[0067] Specifically, the fixed bracket 120 includes a support portion 121 and limiting arms 122 connected to the support portion 121. Two limiting arms 122 are provided and spaced apart along the width direction of the lamp panel 131. Each of the two limiting arms 122 has a locking protrusion 1221 on its opposite side, and the lamp panel 131 is limited by the locking protrusion 1221 to the side of the support portion 121 opposite to the gallbladder wall portion 112. Each limiting arm 122 has a deformation cutout 1222 at the locking protrusion 1221 to allow the locking protrusion 1221 a certain deformation space; and both opposite locking protrusions 1221 have inclined surfaces, which are gradually arranged from the outside to the inside, facilitating the sliding of the lamp panel 131 into the assembly space jointly defined by the locking protrusion 1221 and the support portion 121.

[0068] The support portion 121 has a through hole 1211 for assembling the lamp bead 132 and the sealing structure 140. A top contact portion 1212 is provided at one end of the through hole 1211 opposite to the wall portion 112, and the top contact portion 1212 can press against the side of the lamp plate 131 opposite to the latching protrusion 1221. This not only ensures stable assembly of the lamp plate 131 but also reduces the contact area between the support portion 121 and the lamp plate 131, thus reducing wear on the lamp plate 131. The assembly hole 111 on the wall portion 112 extends into the through hole 1211 on the support portion 121.

[0069] The support portion 121 and the inner wall portion 112 can be fixed with screws. Alternatively, the support portion 121 can have mounting arms 123 extending on both sides along the width direction of the lamp plate 131, and the mounting arms 123 can be fixed with the inner wall portion 112 with screws. As long as it can satisfy the assembly of the fixing bracket 120 and the inner liner body 110, it is only an example for illustration.

[0070] Alternatively, the light panel 131 can also be connected to the fixed bracket 120 by screws, or connected between the fixed bracket 120 and the inner liner body 110 by screws.

[0071] like Figure 1 and Figure 7 As shown, in actual use, the lamp panel assembly 130 is provided with multiple sets, which can be arranged along the height direction of the inner liner body 110 (i.e., Figure 1The lamp panels are arranged at intervals in the vertical direction. Each lamp panel assembly 130 is provided with a support part 121 and a limiting arm 122 adapted to the support part 121. Any two adjacent support parts 121 are connected into an integrated structure by an assembly arm 123.

[0072] Please see Figures 1 to 3 In some embodiments, the inner liner body 110 is made of stainless steel to improve the safety of the sterilization inner liner 100. The fixing bracket 120 can be made of high-temperature resistant hard plastic to ensure assembly reliability.

[0073] like Figures 1 to 4 As shown, this application also provides a disinfection cabinet, including the aforementioned disinfection inner liner 100 and a cabinet body surrounding the disinfection inner liner 100, with a cabinet door movably connected to the cabinet body. Due to the gradually expanding section 1111 of the mounting hole 111 on the inner liner body 110, the obstruction of the LED beads 132 is reduced, allowing the light from the LED beads 132 to diffuse as fully as possible into the liner cavity 1101, thus improving the sterilization effect. Simultaneously, the pressing section 1112 extending axially along the mounting hole 111, while ensuring reliable assembly with the lamp plate 131 to achieve the sealing structure 140, reduces the space occupied by a single mounting hole 111 on the liner wall 112, and utilizes the close proximity of multiple LED beads 132 to further enhance the sterilization effect.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
