Description

Technical Field

[0001] The invention relates to the technical field of medical disinfection devices, and in particular to an ultraviolet disinfection device which adopts an automatic control principle and can flexibly and cyclically lift and lower a multi-layer storage plate. Background Art

[0002] Ultraviolet disinfection is a method of disinfection and sterilization used in scientific research, clinical practice and daily life. It mainly destroys the genetic structure of pathogens through ultraviolet rays of a certain wavelength and kills pathogens that are intolerant to ultraviolet rays (such as coronaviruses). However, the physical properties of ultraviolet rays determine that they can only propagate in a straight line, and the energy attenuation is faster when penetrating through multi-layer objects, which also reduces the disinfection and sterilization effect. This is contrary to the strict aseptic operation principle of medicine, which limits the widespread use of ultraviolet disinfection. Ensuring the disinfection effect of ultraviolet rays is the prerequisite for the widespread application of ultraviolet disinfection.

[0003] Since ultraviolet rays are harmful to the human body, small items are usually disinfected using ultraviolet light disinfection boxes. However, traditional disinfection boxes have problems such as small available space, the risk of inaccurate disinfection of multiple items, and limited storage capacity. How to maximize the use of disinfection boxes to disinfect as many small items as possible at a time is currently a difficult problem to solve clinically.

[0004] In summary, using certain methods in a small space to minimize the attenuation of ultraviolet radiation as much as possible and maximize the ultraviolet radiation on all surfaces that need to be disinfected is a potential solution.

[0005] At present, the disinfection of some small items is limited to relatively mild sterilization methods such as ultraviolet disinfection, otherwise the structure itself will be damaged and difficult to use. For example, in the case of insufficient supply of materials, disposable masks can be used for a second time as an emergency measure if they are worn for a short time and are not heavily contaminated. However, disposable masks cannot be disinfected using methods such as high-pressure steam, high heat, and alcohol disinfection. Only mild methods such as ultraviolet rays can be used to reduce damage to the structure and function of disposable masks.

[0006] Traditional disinfection boxes have volume limitations and can hold fewer items; in addition, the sterilization and disinfection method also has certain requirements for the spatial placement and distance of the items to be disinfected. For example, the Chinese utility model patent "Ultraviolet Disinfection Box", application number CN201320608954.1, discloses a technical solution including a square shell, a revolving door on the front of the shell, and 2-3 ultraviolet lamps placed vertically on the six inner surfaces of the shell. Although the disinfection box can provide a disinfection environment with set temperature and time. However, its disinfection effect is not good and it cannot be disinfected evenly. Moreover, the function is single and it is difficult to meet the use requirements.

[0007] Therefore, the available space of traditional disinfection boxes is severely limited. If small items are disinfected separately, it will waste time and energy, and the efficiency is insufficient, which is a problem that is difficult to solve at present. Taking disposable masks as an example, items used by different people should avoid contact with each other. Traditional disinfection boxes are difficult to achieve the function of disinfecting as many masks as possible at a time. Summary of the invention

[0008] A technical solution provided by the present invention is a multi-layer circulating ultraviolet disinfection box with automatic lifting function, which solves the problems of insufficient and inaccurate ultraviolet radiation and limited available space in traditional disinfection boxes, and ultimately achieves the purpose of ensuring the sterilization effect and increasing the amount of disinfected items.

[0009] The technical solution of the present invention is: a multi-layer circulating ultraviolet disinfection box, the main structure of which includes four parts: a storage device, a line-controlled moving device, an ultraviolet irradiation device, and a disinfection box frame structure.

[0010] The disinfection box uses a wire-controlled moving device with a pre-programmed moving program to move multiple storage layers in the storage device up and down in a circular motion, thereby maximizing ultraviolet radiation and indirectly increasing the storage space.

[0011] The disinfection box frame structure includes a disinfection box shell, a partition, an operation panel and a box door. The disinfection box shell is generally a rectangular box structure, and is made of a material that completely blocks ultraviolet rays.

[0012] The partition is located in the center of the disinfection box, dividing the disinfection box into two parts, the disinfection area on one side and the transmission area on the other side. The inner wall of the top plate of the disinfection area is attached with a thickened high magnetic plate (magnetic top plate) for the adsorption of the magnet on the top storage plate. The back plate of the transmission area is embedded with a wire control device.

[0013] The storage layer is installed in the disinfection area in the form of a storage board, which specifically includes: a plurality of vertically arranged storage boards and a groove-shaped guide rail. The number of storage board layers can be freely selected according to needs.

[0014] There are four rails connecting the upper and lower plates of the disinfection box. The positions of the four rails match the dimensions of the four corners of the storage layer. The cross section of the rail is a "concave" structure from the outside to the inside, and the rail is not ferromagnetic.

[0015] Each storage board is generally a flat rectangular frame structure, with features such as four flat hooks in the middle and side ends extending from the four corners.

[0016] The side ends extending outwards from the four corners of the storage plate are placed in the guide rails. The design of the guide rails surrounding the four corners is used to maintain the movement track of the storage plate and reduce external interference with the magnet during operation.

[0017] A rectangular high-magnetism magnet of equal length and width is pasted on the upper and lower sides of the four corners. The length and width of the magnet piece match the inner wall size of the guide rail, and the thickness h of the magnet piece is adapted to the height H of the object to be sterilized (h>1 / 2H).

[0018] The storage board and the top plate (magnetic top plate) in the disinfection box, and the storage boards can be magnetically adsorbed to each other. The magnetic adsorption design concept is simple and convenient, and is used to fix the storage board after it is moved to the ideal position.

[0019] Each storage board has four flat hooks, which are used to support items to be disinfected. The items can be placed flat, and masks and other disinfected items can also be hung on the four hooks with ropes on both sides and placed. The advantage of the flat hook structure is that the upper and lower surfaces of the items to be disinfected are exposed as much as possible to facilitate ultraviolet irradiation. The structure providing support is not limited to flat hooks. The hooks can be replaced with hollow structures. The hollow structures in this solution include but are not limited to the following methods: silk thread, cylinder, mesh frame, plate and other structures. Different hollow structures are used for disinfection of different types of items.

[0020] The wire-controlled moving device is located in the transmission area, and specifically includes a guide component and a telescopic component.

[0021] The guide assembly is a working device that realizes the cyclic lifting function of the multi-layer board. The guide assembly includes an upper block, a lower block, a screw rod, a slider, a telescopic middle rod, a telescopic end rod and a chuck. The upper block and the lower block are mainly used to fix the screw rod, and the rotation of the screw rod can drive the slider to slide up and down.

[0022] The joint extension of the middle rod and the end rod can send the chuck to a suitable position. The maximum distance of the joint extension of the middle rod and the end rod is just enough to insert the chuck into the flat frame on the right side of the storage board. Specifically, there is a vertical long slit in the middle of the partition for the extension and lifting of the middle rod, the end rod and the chuck. The distance between the chucks matches the thickness of the edge of the flat storage board, which is used to clamp and move the storage board.

[0023] The wire-controlled moving device is operated and controlled by a control system integrated on the circuit board. The wire-controlled system is the core device for realizing the cyclic lifting of the multi-layer storage board. The control system is a programmed circuit board located on the back panel of the disinfection box. The circuit control unit on the circuit board includes: ultraviolet lamp electronic control module, transmission component electronic control module, display screen electronic control module, and circuit timing control module. Its main functions include calibrating the position of the slider, rotating the screw rod to drive the slider to slide, and extending and retracting the middle rod and end rod, and finally realizing the function of accurately inserting the chuck into the right side of the storage board and moving the storage board. Secondary functions include setting the timer, switching the ultraviolet lamp, and connecting the power supply.

[0024] The ultraviolet irradiation device in the disinfection area includes an ultraviolet lamp and an ultraviolet radiation meter. The ultraviolet lamp is located on the rear inner wall of the disinfection area. Multiple vertical parallel ultraviolet lamps can control the switch of single or multiple ultraviolet lamps as needed. The advantage of the multiple ultraviolet lamp design is that it solves the problem of insufficient radiation illumination or damage of a single ultraviolet lamp due to long-term use. Ultraviolet sensors are also arranged in the disinfection area, and the values ​​detected by the ultraviolet sensors will be displayed on the screen of the disinfection box operation panel.

[0025] The upper door of the disinfection box, i.e. the door panel, is located in front of the disinfection area and is made of a transparent glass plate that can block ultraviolet radiation. The operation panel is located on the right side of the door and includes two upper and lower control knobs and a liquid crystal display panel. The upper control knob is used to control the irradiation switch and the working timer, and the lower control knob is used to control the number of open ultraviolet lamps. The liquid crystal display panel is used to display the ultraviolet radiation illumination value and the working countdown. When the illumination is insufficient, the number of ultraviolet lamps can be increased or replaced in time.

[0026] The advantages of the present invention are:

[0027] 1. The overall structural design of the multi-layer storage board and the guide rail is novel, and the storage layer adopts the magnetic adsorption design concept.

[0028] 2. The mobile device has an ingenious structural design and a clear control principle.

[0029] 3. The flat shape of the multi-layer storage board matches the clamp of the moving device, and the hollow structure on the storage board is reasonably designed.

[0030] 4. The LCD screen of the disinfection box is beautifully designed to display the ultraviolet radiation illumination and the display is clear and comprehensive.

[0031] 5. The UV lamps are vertically arranged and can be replaced in an emergency. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] (ii) The storage device is located in the disinfection area and includes a plurality of vertically arranged multi-layer storage boards 2 and guide rails. The number of layers of the storage boards 2 can be freely selected according to needs.

[0047] Each layer of the storage board 2 is generally a flat rectangular frame structure, having four flat hooks 21 in the middle, side ends 22 extending from four corners, and other features:

[0048] 1. Flat hooks 21: Four flat hooks 21 are used to support items to be sterilized. The items can be placed flat. Masks and other sterilized items can also be hung on the four hooks with ropes on both sides and spread out. The advantage of the flat hook 21 structure is that the upper and lower surfaces of the items to be sterilized are exposed as much as possible to facilitate ultraviolet irradiation. The structure that provides support is not limited to the flat hooks 21. The hooks can be replaced by structures such as silk threads, cylinders, mesh frames, plates, etc., for the disinfection of different types of items.

[0049] 2. Side ends extending from corners: The four corners of the storage board have side ends 22 extending outward, and the side ends 22 are placed in the guide rail. A rectangular high-magnetic magnet 23 of equal length and width is pasted on the upper and lower sides of the four side ends. The length and width of the magnet sheet match the size of the inner wall of the guide rail, and the thickness h of the magnet sheet is adapted to the height H of the items to be sterilized (h>1 / 2H). The storage board and the top plate (magnetic top plate) in the disinfection box, and each storage board can be magnetically adsorbed to each other. The magnetic adsorption design concept is simple and convenient, and is used to fix the storage board 2 after it is moved to the ideal position.

[0050] There are four guide rails 3 connecting the upper and lower plates of the disinfection box, matching the size of the upper end portions 2 of the four corners. The cross section of the guide rail 3 is a "concave" structure from the outside to the inside, and the guide rail 3 is not ferromagnetic. The design of the guide rail 3 surrounding the four corners is used to maintain the movement track of the storage plate and reduce the interference of the outside world on the magnet during operation.

[0051] (3) The wire-controlled moving device is located in the transmission area, including the moving device and the wire-controlled device.

[0052] 1. Moving device: The moving device is a working device that realizes the cyclic lifting function of the multi-layer board. The moving device includes an upper block 4, a lower block 5, a screw rod 6, a slider 7, a middle rod 8, an end rod 9 and a chuck 10. The upper block 4 and the lower block 5 are mainly used to fix the screw rod 6; the rotation of the screw rod 6 can drive the slider 7 to slide up and down; the joint extension of the middle rod 8 and the end rod 9 can send the chuck 10 to a suitable position, and the maximum distance of the joint extension of the middle rod 8 and the end rod 9 can just allow the chuck to be inserted into the right flat frame of the storage board 2; the spacing of the chuck 10 matches the thickness of the edge of the flat storage board 2, and is used to clamp and move the storage board 2.

[0053] 2. Wire control system: The wire control system is the core structure to realize the cyclic lifting of the multi-layer storage board 2. The wire control system is a programmed circuit board located on the back plate of the disinfection box. The main functional features include the calibration of the slider position, the rotation of the screw rod 6 to drive the slider 7 to slide, the extension of the middle rod 8 and the end rod 9, and finally the accurate insertion of the chuck into the right side of the storage board 2 and the movement of the storage board 2. Secondary functions include the setting of the timer, the switch of the ultraviolet lamp, and the power connection.

[0054] (IV) Ultraviolet radiation devices include ultraviolet lamps and ultraviolet radiation illuminometers.

[0055] 1. Ultraviolet lamp 16: The ultraviolet lamp 16 is located on the rear inner wall of the disinfection area. It is characterized by multiple vertical parallel ultraviolet lamps. The control switch on the operation panel can be used to select a single or multiple ultraviolet lamps to work. The advantage of the multiple ultraviolet lamp design is that it solves the problem of insufficient radiation illumination or damage of a single ultraviolet lamp due to long-term use.

[0056] 2. Ultraviolet radiation illuminometer: The ultraviolet sensor is located in the disinfection area, and the value display is located on the screen of the disinfection box operation panel 12.

[0057] Embodiment 2:

[0058] like Figure 2 and 3 As shown, the left side is the disinfection area, which mainly includes the storage board 2, the guide rail 3, and the ultraviolet lamp 16; the right side is the transmission area, which mainly includes the wire-controlled moving device. The two areas are separated by a partition 11, and there is a vertical long slit in the middle of the partition 11 for the extension and lifting of the middle rod 8, the end rod 9, and the clamp 10. The four corners of the storage board 2 are matched in the guide rail 3, and the multi-layer arrangement is arranged. The magnets on the four corners attract each other, and the top storage board 2 can absorb the magnetic top plate.

[0059] like Figure 3 and 4 As shown, a plurality of storage plates 2 are stacked and placed at four corners to fit in the guide rail 3. The storage plates 2 are generally flat rectangular frame structures, with four flat hooks 21 in the middle and side features extending from the four corners. A rectangular high-magnetic magnet 23 of equal length and width is pasted on the upper and lower sides of the side ends of the four corners.

[0060] like Figure 5 and 6 As shown, the wire hole moving device includes an upper block 4, a lower block 5, a screw rod 6, a slider 7, a telescopic middle rod 8, a telescopic end rod 9 and a chuck 10. The upper block 4 and the lower block 5 are mainly used to fix the screw rod 6; the rotation of the screw rod 6 can drive the slider 7 to slide up and down; the joint telescopic movement of the middle rod 8 and the end rod 9 can send the chuck 10 to a suitable position; the chuck 10 can be inserted into the right side of the flat storage plate to move the storage plate 2.

[0061] like Figure 1 As shown, the front of the disinfection box includes a transparent glass door that can block ultraviolet rays, an LCD display and two control knobs.

[0062] The disinfection box adopts the principle of automatic control and a programming design driver, and can flexibly lift and lower the multi-layer storage plates in a small space in an orderly manner and circulate them to increase the range of direct contact between the items and ultraviolet rays, thereby solving the above problems.

[0063] Embodiment 3:

[0064] This disinfection box uses the principle of automatic control to realize the flexible and orderly lifting and sterilization of multi-layer storage boards in a small space through a mobile device, ultimately achieving the purpose of increasing the amount of items to be disinfected at a time and ensuring the disinfection effect. Taking the disinfection of multiple disposable masks as an example, the steps are as follows:

[0065] 1. Open the door of the disinfection box, put the disposable mask with the outside facing up, and put the hanging ropes on the four hooks of the first layer (i.e. the top layer) of the storage board respectively. The mask will be automatically flattened, and the entire storage board will be manually slid up to the top to make the storage board and the magnetic top board firmly adsorbed. Operate the remaining multiple masks in the same way, and manually push each layer of storage board to the top to adsorb it with the previous storage board. When the masks are placed, push all the storage boards with masks placed on them back to the bottom of the disinfection box. At this time, all the storage boards (a total of N layers) are at the bottom of the disinfection box.

[0066] 2. Close the disinfection box door and turn on the power. At this time, the telescopic middle rod and end rod of the mobile device are in the shortest position, and the slider is at the lowest level. The lower control knob selects the number of UV lamps to be used; the upper control knob is adjusted from closed to the required disinfection time scale, and the knob countdown begins.

[0067] 3. Disinfection begins, the ultraviolet lamp lights up, and the wire control device automatically calibrates to zero.

[0068] 4. According to the programming settings, the screw rod rotates to drive the slider to move upward to the level of the first layer of the storage plate. The middle rod and the end rod gradually extend to the longest length and then stop. At this time, the chuck is inserted into the flat frame on the right side of the first layer of the storage plate.

[0069] 5. The screw rod rotates and drives the slider to move upward to the top and then stops. At this time, the first layer of storage plate is adsorbed by the magnetic top plate, the middle rod and the end rod are shortened and retracted, and the chuck releases the Nth layer of storage plate.

[0070] 6. Repeat steps 4-5 by analogy. The screw rod rotates to drive the slider to move upward to the level of the second layer of the board, and the second layer of the board is moved upward to be adsorbed with the first layer of the board. This cycle repeats until the Nth layer of the board moves upward to be adsorbed with the N-1th layer of the board, the middle rod and the end rod are retracted, and the chuck releases the Nth layer of the board.

[0071] 7. According to the programming settings, the rotation of the screw rod drives the slider to be at the level of the Nth layer (i.e. the bottom layer) storage plate. The middle rod and the end rod gradually extend to the longest and then stop. At this time, the chuck is inserted into the flat frame on the right side of the Nth layer storage plate.

[0072] 8. The screw rod rotates and drives the slider to move downward to the bottom and then stops. The middle rod and the end rod are shortened and retracted. The chuck releases the Nth layer storage plate, and the middle rod and the end rod are retracted.

[0073] 9. Repeat steps 7-8 by analogy. The screw rod rotates to drive the slider to move upward to the level of the N-1th layer of the board, and the N-1th layer of the board is moved downward to be adsorbed with the Nth layer of the board. This reciprocating cycle continues until the first layer of the board moves downward to be adsorbed with the second layer of the board, the middle rod and the end rod are retracted, and the chuck releases the first layer of the board.

[0074] 10. Steps 4-9 are a cycle, and the sterilization is repeated in this way. The storage plates rise and fall in sequence. Each time a single storage plate rises and falls, the entire mask is almost completely irradiated by ultraviolet rays without any obstruction, achieving maximum sterilization operation.

[0075] 11. During the disinfection process, the ultraviolet irradiance value can be observed on the LCD screen to ensure sufficient irradiation intensity.

[0076] 12. When the countdown time of the upper knob is up, it returns to the closed position, the disinfection is completed, the ultraviolet lamp is turned off, and the moving device returns to the original position, that is, the middle rod and the end rod are both in the shortest retracted position, and the slider is at the lowest level.

[0077] 13. Open the disinfection box and take out the disinfected mask.

[0078] The embodiments of the present invention are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present invention should still be covered by the claims of the present invention.
