Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and more specifically, to a packaging box that is sterilized by both ultraviolet light and plasma. Background Technology

[0002] Packaging boxes are basic containers whose core function is storage. They are mainly used to organize and protect items, preventing them from being affected by dust during storage or transportation. In daily life and production, various reusable products (such as makeup brushes, tableware, small medical accessories, etc.) need to be stored in packaging boxes.

[0003] However, the existing packaging boxes have the following problems when used: However, most existing packaging boxes only provide basic storage and lack effective sterilization capabilities. This leads to the proliferation of bacteria, mold, and other microorganisms in the sealed environment inside the boxes during long-term product storage. These microorganisms adhere to the product surface, and some pathogens are difficult to remove through routine cleaning. Long-term use poses a significant threat to human health. To address microbial contamination, users often resort to cleaning or high-temperature sterilization. However, these methods have limitations: firstly, cleaning before each use is cumbersome and inconvenient for users; secondly, most product materials (such as plastic and rubber) cannot withstand high-temperature sterilization, which can cause deformation and damage, affecting their lifespan. Furthermore, even if some packaging or sterilization equipment uses only ultraviolet (UV) sterilization, the linear propagation of UV light makes it difficult to cover the entire surface of the item. Hidden areas such as the back and crevices are prone to sterilization dead zones, preventing thorough disinfection and leaving a risk of microbial residue.

[0004] This utility model can store items and protect them from dust damage through an outer shell and a drawer-type inner shell, just like a regular storage box. It can also achieve dual sterilization by using ultraviolet sterilization lamp strips and negative ion generators, solving the problem of microbial growth in stored items and meeting the needs of convenient storage and thorough disinfection.

[0007] A further preferred embodiment: guide rails are fixedly installed on the front and rear ends and the upper and lower sides inside the outer shell, and limit strips are fixedly installed between the guide rails.

[0008] A further preferred embodiment: a limiting strip at the rear end of the inner shell is installed on the left side, a limiting strip at the front end of the inner shell is installed on the right side, and the guide rail is slidably connected to the inner shell.

[0009] A further preferred embodiment: the outer shell has an embedding groove at both the front and rear ends, and the embedding groove has an extension groove at both the left and right ends.

[0010] A further preferred embodiment: the limiting strip is inserted into the embedded groove for fixed connection, and fixed ends are fixedly installed at both ends of the limiting strip. The fixed ends are embedded into the extension groove for connection, and screws are threadedly connected to the surface of the fixed ends, with the screws threadedly connected to the outer shell.

[0011] A further preferred embodiment: the inner shell has sliding grooves on the front and rear ends and the upper and lower sides, the sliding grooves are slidably connected to the guide rail, and limit strips are fixedly installed between the sliding grooves.

[0012] A further preferred embodiment: the second limiting strip at the rear end of the inner shell is installed on the right side, and the second limiting strip at the front end of the inner shell is installed on the left side.

[0013] A further preferred embodiment: the first limiting strip and the second limiting strip cooperate with each other, with the first limiting strip acting as a blocking and limiting element. Beneficial effects

[0014] 1. By setting guide rails, slide grooves, limit bar one and limit bar two, the embedded cooperation of guide rails and slide grooves provides directional guidance for the sliding of the inner shell, effectively preventing the inner shell from moving up and down, shifting forward and backward or getting stuck when sliding, ensuring smooth pulling and improving the user operation experience. The cross cooperation of limit bar one and limit bar two can prevent the inner shell from falling off the guide rail when it is pulled out, ensuring the integrity of the equipment structure and the safety of use. 2. By incorporating an embedding groove, an extension groove, and screws, the device provides installation space for the first limiting strip to accommodate its main body and position its two ends. This allows the first limiting strip to be precisely embedded into the outer shell, preventing positional shifts during installation. It also forms a dual positioning structure, ensuring a tighter fit between the first limiting strip and the outer shell, providing a stable foundation for the subsequent blocking of the second limiting strip. The threaded connection design of the screws firmly locks the fixed end of the first limiting strip in the extension groove. This dual reinforcement prevents the first limiting strip from loosening or shifting due to sliding collisions with the inner shell during long-term use, ensuring it maintains stable blocking force and reliable limiting function. Furthermore, the detachable nature of the screws allows the first limiting strip to be removed when the inner shell needs to be completely withdrawn, breaking the extraction limitation. This balances daily safety with operational flexibility in special scenarios, improving the ease of use and adaptability of the device. 3. Equipped with UV sterilization lamps and a negative ion generator, the UV sterilization lamps emit standard UVC band ultraviolet light, irradiating the surface of items in a straight line. By destroying the DNA / RNA structure of microorganisms, it quickly kills bacteria and viruses in the light-covered area, achieving highly efficient targeted sterilization and providing basic and powerful disinfection protection for item surfaces. The negative ion generator produces a large amount of negatively charged plasma, which diffuses freely due to the internal space characteristics of the packaging box, penetrating corners, gaps, and shadows where UV light cannot directly reach. By destroying the cell membranes or enzyme activity of microorganisms, it performs secondary disinfection of residual microorganisms, compensating for the limitations of direct UV irradiation and forming a sterilization effect without dead angles. The two work together to achieve a dual sterilization mode of targeted disinfection and comprehensive coverage, greatly improving the thoroughness of sterilization. It can effectively cover both the surface and hidden areas of items, giving users more peace of mind when using items and enhancing the practicality of the equipment. 4. In summary, this packaging box, which utilizes both ultraviolet light and plasma sterilization, incorporates a structure including guide rails, sliding grooves, limiting strip one, limiting strip two, ultraviolet sterilization lamp strips, and a negative ion generator. The embedded cooperation of the guide rails and sliding grooves provides directional guidance for the inner shell, ensuring smooth and non-deviation-prone sliding. The cross-blocking of limiting strip one and limiting strip two prevents the inner shell from falling off during extraction. The directional disinfection and comprehensive coverage of the ultraviolet sterilization lamp strips and negative ion generator can cover the surface of items and hidden corners, thoroughly eliminating microorganisms and overcoming the limitations of single sterilization methods. The multiple structures support each other, making operation convenient and stable while significantly improving sterilization thoroughness. It is suitable for various item needs, providing users with a safe and reliable sterilization experience. Attached Figure Description

[0020] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0021] Please see Figure 1-4 In this embodiment of the present invention, a packaging box for dual sterilization by ultraviolet light and plasma includes: an outer shell 1, an inner shell 2 slidably connected inside the outer shell 1, the outer shell 1 being hollow inside and without baffles at both ends, the inner shell 2 being drawer-shaped and without baffles at the top, a magnetic attractor being provided in the middle of either end of the front or rear of the outer shell 1, and the magnetic attractor being magnetically connected to the inner shell 2, a through hole 201 being provided at the left end of the inner shell 2, a self-locking switch 202 being fixedly installed in the through hole 201, a light strip slot 203 being fixedly installed around the middle of the inner shell 2, an ultraviolet sterilization light strip 204 being fixedly installed in the light strip slot 203, a control board 205 being fixedly installed on the front side of the inner shell 2, a storage battery 206 being fixedly installed on the right side of the control board 205, and a negative ion generator 207 being fixedly installed on the rear side of the control board 205; The positive terminal and lower right corner of the self-locking switch 202 are electrically connected to the positive terminals of the UV sterilization lamp strip 204 and the negative ion generator 207; the negative terminal of the self-locking switch 202 is connected in parallel with the negative terminals of the UV sterilization lamp strip 204, the control board 205, the energy storage battery 206, and the negative ion generator 207; the lower left corner of the positive terminal of the self-locking switch 202 is connected in parallel with the positive terminals of the energy storage battery 206 and the control board 205. The outer shell 1 is hollow inside and has no baffles at the left and right ends, providing a sliding channel for the inner shell 2; the inner shell 2 is in the shape of an inner drawer. The design features an open top panel, allowing users to easily place or remove items to be sterilized from the top. The inner shell 2 is magnetically positioned via a magnetic chuck within the outer shell 1, maintaining ease of item placement and creating a relatively sealed sterilization space upon subsequent closure. The inner shell's complete insertion ensures a tight seal, preventing plasma leakage. The energy storage battery 206 pre-stores electrical energy to power the entire system. With the self-locking switch 202 in an untriggered, open state, the UV sterilization lamp strip 204 and negative ion generator 207 are not powered, and the control board 205 is in a neutral position. In low-power standby mode, to avoid energy waste, users can directly place the items to be sterilized into the drawer-shaped inner shell 2 from the top of the inner shell 2. When placing the items, ensure that the height of the items does not exceed the side wall of the inner shell 2 to avoid affecting the subsequent pushing and closing of the inner shell. At the same time, do not block the ultraviolet sterilization lamp strip 204 at the lamp strip slot 203 in the middle of the inner shell 2 to ensure unobstructed light irradiation and to not hinder the diffusion of negative ions. Users manually push the drawer-shaped inner shell 2 inward along the hollow channel of the outer shell 1 until the inner shell 2 slides completely into the outer shell 1. Inside, the area without a baffle on the top of the inner shell 2 is shielded by the top structure of the outer shell 1, forming a closed sterilization space. During the pushing process, the self-locking switch 202 on the left end of the inner shell 2 is switched from the open state to the closed state, completing the physical triggering of the circuit start-up; at the same time, the magnetic attractor inside the outer shell 1 magnetically attracts the inner shell 2, fixing the position of the inner shell and preventing accidental slippage during sterilization. After the self-locking switch 202 is closed, the power of the energy storage battery 206 is distributed through the switch to synchronously power different functional components. The specific circuit path is as follows: Positive path 1: The positive terminal of the self-locking switch 202 and the lower right corner of the positive terminal are directly connected to the positive terminal of the ultraviolet sterilization lamp strip 204 and the positive terminal of the negative ion generator 207, ensuring that the two sterilization components start immediately after receiving power; Positive path 2: The lower left corner of the positive terminal of the self-locking switch 202 is connected in parallel to the positive terminal of the energy storage battery 206 and the positive terminal of the control board 205. On the one hand, it supplies power to the control board 205 to enable it to enter the working state, and on the other hand, it completes the power supply circuit of the energy storage battery to avoid power outages caused by single-point failures. Negative common path: The negative terminals of UV sterilization lamp strip 204, control board 205, energy storage battery 206, and negative ion generator 207 are all connected in parallel to the negative terminal of self-locking switch 202, forming a complete current loop to ensure that all components work stably in the enclosed space and are not affected by structural sliding. After the circuit is turned on, the UV sterilization lamp strip 204 and the negative ion generator 207 work synchronously. Combining the advantages of the drawer-shaped inner shell without a top baffle for open access and the sealing effect after closing, sterilization is achieved through complementary methods of directional irradiation and global diffusion. After the UV sterilization lamp strip 204, which is fixed in the lamp strip slot 203 in the middle of the inner shell 2, is activated, it emits UV light with a wavelength that meets the sterilization standard, usually in the UVC band of 200-280nm, which irradiates the surface of the items inside the drawer-shaped inner shell 2 in a straight line. Since the inner shell has no top baffle and forms a seal with the outer shell after closing, The enclosed space prevents light leakage while concentrating its coverage on the top, bottom, and sides of objects. By disrupting the DNA / RNA structure of microorganisms, it disables their reproductive capabilities, achieving highly efficient disinfection of light-covered areas. When the negative ion generator 207 on the front of the inner shell 2 is activated, it generates a large number of negatively charged ions. Utilizing the hollow outer shell 1 and the drawer-like transparent structure of the inner shell 2, the plasma can freely diffuse to every corner of the inner shell, including areas where ultraviolet light cannot directly reach, such as the gaps where the bottom of objects contacts the inner shell and the shadows created by stacked objects. These negative ions, through contact with the surface of microorganisms, disrupt their cell membrane structure or enzyme activity, further eliminating residual microorganisms not covered by ultraviolet light, forming a comprehensive secondary sterilization without dead angles. This overcomes the limitations of direct ultraviolet irradiation. With the self-locking switch 202 closed, i.e., the inner shell 2 is fully pushed into the outer shell 1, the magnetic accumulator remains magnetically fixed, the circuit remains continuously conductive, and the ultraviolet sterilization lamp strip 204 and negative ion generator 207 continue to operate. The control board 205 monitors the operating status in real time and automatically cuts off the circuit after the set time to avoid excessive power consumption. Prolonged exposure to ultraviolet light will affect the items. If no time limit is set, the system will continue to operate until the user manually terminates the process or the battery is depleted. When the user needs to remove the items, they should manually push the inner shell 2 and use its drawer-like structure to slide it out along the hollow channel of the outer shell 1. At this time, the magnetic connection of the magnetic suction body will be released, and the self-locking switch 202 will be switched from the closed state to the open state. The circuit will be cut off, and all sterilization components will stop working. The user can then directly remove the sterilized items from the top of the inner shell 2 where there is no baffle. The entire sterilization process is now complete, and the items are ready for the next use.

[0022] In this embodiment of the utility model, guide rails 101 are fixedly installed on both the upper and lower sides of the front and rear ends inside the outer shell 1, and limit strips 104 are fixedly installed between the guide rails 101. The limit strip 104 at the rear end inside the outer shell 1 is installed on the left side, and the limit strip 104 at the front end inside the outer shell 1 is installed on the right side. The guide rails 101 are slidably connected to the inner shell 2. Slide grooves 208 are provided on both the upper and lower sides of the front and rear ends of the inner shell 2. The slide grooves 208 are slidably connected to the guide rails 101. Limit strips 209 are fixedly installed between the slide grooves 208. The limit strip 209 at the rear end of the inner shell 2 is installed on the right side. The second limiting strip 209 at the front end is installed on the left side. The first limiting strip 104 cooperates with the second limiting strip 209, and the first limiting strip 104 blocks and limits the second limiting strip 209. Parallel guide rails 101 are fixedly installed on the upper and lower sides of the front and rear ends inside the outer shell 1, and a positioning limiting strip 104 is fixed between every two sets of guide rails 101. The first limiting strip 104 at the rear end inside the outer shell 1 is located on the left side, and the first limiting strip 104 at the front end is located on the right side, forming an asymmetrical distribution with the rear end on the left and the front end on the right. Correspondingly, the upper and lower sides of the front and rear ends of the inner shell 2 are provided with corresponding guide rails. The guide rail 101 provides a matching sliding groove 208. A second limiting strip 209, corresponding to the first limiting strip 104, is fixed between the sliding grooves 208. The second limiting strip 209 at the rear end of the inner housing 2 is located on the right, and the second limiting strip 209 at the front end is located on the left, forming a left-right corresponding and cross-fitting layout with the first limiting strip 104 of the outer housing 1. The guide rail 101 provides a directional sliding track for the sliding grooves 208, preventing the inner housing 2 from shifting in the front-back and up-down directions. When the inner housing 2 is pushed, the second limiting strip 209 of the inner housing 2 moves outward synchronously with the housing. When the inner housing 2 is about to be completely pulled out of the outer housing 1, the second limiting strip... The second 209 will form a reverse contact with the first 104. For example, the second 209 on the right rear end of the inner housing 2 will abut against the first 104 on the left rear end of the outer housing 1. The first 104 prevents the inner housing 2 from detaching from the guide rail 101 of the outer housing 1 due to excessive pulling out by blocking the second 209, thus ensuring the structural integrity and safety of the equipment. If the inner housing 2 is pushed in the opposite direction, the first 104 at the front end of the outer housing 1 will abut against the second 209 at the front end of the inner housing 2, thus preventing the inner housing 2 from detaching from the guide rail 101 of the outer housing 1 due to excessive pulling out.

[0023] In this embodiment of the present invention, the front and rear ends of the outer shell 1 are provided with embedding grooves 102, and the left and right ends of the embedding grooves 102 are provided with extension grooves 103. The limiting strip 104 is inserted into the embedding groove 102 and fixedly connected. The left and right ends of the limiting strip 104 are fixedly installed with fixing ends 105, which are embedded in the extension grooves 103 and connected. The surface of the fixing ends 105 is threaded with screws 106, which are threaded to the outer shell 1. The front and rear ends of the outer shell 1 are pre-formed with embedding grooves 102 that match the size of the limiting strip 104, and the left and right ends of the embedding grooves 102 extend to provide extension grooves 103. The embedding grooves 102 are used to accommodate the main body of the limiting strip 104, and the extension grooves 103 are used to accommodate the fixing ends 105 of the limiting strip 104. The dual positioning structure, consisting of a main body embedded and two ends fixed, ensures that the limiting strip 104 does not shift after installation. After the extension groove 103 is embedded in the fixed end 105, the screw 106 is aligned with the pre-set threaded hole on the surface of the fixed end 105. Tightening the screw 106 clockwise will cause it to pass through the threaded hole of the fixed end 105 and form a threaded connection with the threaded structure on the inner wall of the extension groove 103 of the outer shell 1. By locking the screws at both ends, the limiting strip 104 is firmly fixed in the embedded groove 102, preventing it from loosening or shifting during the subsequent sliding of the inner shell 2. This ensures that the limiting strip 104 always maintains a stable blocking and limiting ability. Furthermore, when it is necessary to completely pull out the inner shell 2, the limiting strip 104 can be removed by unscrewing the screw 106, so that the inner shell 2 will not be affected when it is pulled out.
