Description

Technical Field

[0001] This utility model relates to the field of public health disinfection equipment technology, and more specifically, to a portable rapid ultraviolet disinfection box for use in public health settings. Background Technology

[0002] In public health and epidemic prevention, items such as express parcels, hotel luggage, and office documents are prone to harboring pathogens such as Staphylococcus aureus and Escherichia coli, and disinfection equipment is needed to reduce the risk of transmission.

[0003] Currently available UV disinfection equipment has some shortcomings. For example, traditional disinfection boxes are mostly of fixed volume. If the volume meets the disinfection requirements of A4-sized items, they are heavy and bulky, making them difficult to carry to mobile scenarios such as express delivery stations and hotel rooms. If portability is the priority, the volume is too small to accommodate items that need regular disinfection.

[0004] Existing disinfection boxes use a single ultraviolet light source (such as a low-pressure mercury lamp), which has insufficient power (≤30W). It takes 5-30 minutes to kill common pathogens, which is difficult to meet the demand for "rapid disinfection". At the same time, there is no reflective junction inside the box, and when items are stacked or blocked, it is easy to form irradiation dead corners, resulting in incomplete sterilization.

[0005] In view of this, the present invention is proposed to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a portable rapid ultraviolet disinfection box for use in public health facilities, so as to solve the technical problems of fixed volume and incomplete sterilization in the existing disinfection boxes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A portable rapid ultraviolet disinfection box for use in public health facilities includes: The base structure includes a bottom plate, with adjustment rod assemblies on all four sides of the bottom plate and a bottom ultraviolet lamp plate in the center of the bottom plate; The top cover is detachably mounted on the upper part of multiple adjustment rod assemblies, and a top ultraviolet lamp plate is provided at the bottom of the top cover; Multiple prefabricated enclosures are installed between the bottom plate and the top cover, and are fitted onto multiple adjusting rod assemblies. The prefabricated enclosures have central ultraviolet lamp panels on both the front and rear sides. The storage rack is made of plastic perforated board, and its left and right ends can be detachably installed on the left and right sides of the assembled box.

Two adjacent square frames are connected to the embedded groove through the embedded edge. The bottom plate has a bottom groove, and the bottom square frame is connected to the bottom groove through its bottom embedded edge.

[0011] Furthermore, a first socket and a second socket are respectively provided on the bottom side of the top cover and the square frame. The top ultraviolet lamp panel is electrically connected to the first socket, and the middle ultraviolet lamp panel is electrically connected to the second socket. The bottom plate and the square frame are respectively provided with a first socket and a second socket on the same side of the upper surface.

Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0019] See Figures 1 to 5As shown, a portable rapid ultraviolet disinfection box for public health facilities includes: a base structure 1, a top cover 3, multiple assembled boxes 2, and a shelf 7. The base structure 1 includes a bottom plate 11, with adjustment rod assemblies arranged around the bottom plate 11. A bottom ultraviolet lamp plate 5 is arranged in the center of the bottom plate 11. The top cover 3 is detachably mounted on the upper end of the multiple adjustment rod assemblies, and a top ultraviolet lamp plate 10 is arranged at the bottom of the top cover 3. The multiple assembled boxes 2 are installed between the bottom plate 11 and the top cover 3 and are fitted onto the multiple adjustment rod assemblies. A central ultraviolet lamp plate 8 is arranged on both the front and rear sides of the assembled boxes 2. The shelf 7 is a plastic perforated plate, with its left and right ends detachably mounted on the left and right sides of the assembled boxes 2, respectively. Mirrored aluminum plates are arranged on the upper surface of the bottom plate 11, the lower surface of the top cover 3, and the inner side of the assembled boxes 2.

[0020] It should be noted that the surface of the mirror aluminum plate is mirror polished, with a reflectivity of ≥95%, and the back is coated with an adhesive that can withstand temperatures above 80℃, which is tightly bonded to the upper surface, the lower surface of the top cover 3, and the inner side of the assembled box 2. In order to meet the disinfection needs of some items, the shelf 7 can be set as needed. The shelf 7 on some of the assembled box 2 can be removed to place items in layers, ensuring that all surfaces of the items are exposed to ultraviolet light. Combined with the mirror aluminum plate, the surface irradiation coverage of the items is greatly improved. Within 60 seconds, the kill rate of Staphylococcus aureus (ATCC 6538) and Escherichia coli (8099) must be ≥99.9% (i.e., the mean log kill rate ≥3.0). For Escherichia coli, the dose must be ≥20,000 μW·s / cm², and for Staphylococcus aureus, the dose must be ≥10,000 μW·s / cm². To achieve this dose within 60 seconds, the minimum ultraviolet radiation irradiance inside the chamber must be ≥333 μW / cm² (calculated as 20,000 μW·s / cm² ÷ 60s).

[0021] The bottom UV lamp panel 5, the middle UV lamp panel 8, and the top UV lamp panel 10 are the main germicidal light sources, using a UVC-LED array with a wavelength of 265±5nm and a total power of ≥60W. They are suitable for home and express delivery disinfection, hotel luggage disinfection, and office document sterilization.

[0022] In the above scheme, the bottom ultraviolet lamp panel 5, the middle ultraviolet lamp panel 8, and the top ultraviolet lamp panel 10 form a multi-position light source to achieve efficient and thorough sterilization. The adjustable rod assembly and multiple prefabricated boxes 2 allow the height of the adjustable rod assembly and the number of prefabricated boxes 2 to be adjusted according to the disinfection needs, so as to accommodate the common items that need to be disinfected, thereby improving the ability to meet different disinfection needs. Furthermore, the prefabricated boxes 2 are detachable, making them easy to carry and transport, and meeting the needs of mobile disinfection in public health places.

[0023] See some possible implementations. Figure 2As shown, a high-pressure mercury lamp 6 is also installed around the bottom plate 11. The high-pressure mercury lamp 6 is encased in a quartz glass protective tube to prevent mercury leakage due to lamp body breakage. The high-pressure mercury lamp 6 is used to supplement the irradiation of the interior of the ultraviolet disinfection box, and to supplement the irradiation of areas that are difficult to cover by the bottom ultraviolet lamp plate 5, the middle ultraviolet lamp plate 8, and the top ultraviolet lamp plate 10, thereby improving the disinfection effect. A honeycomb activated carbon filter is also installed on the bottom plate 11, which is wrapped with a 10μm pore size non-woven fabric. The high-pressure mercury lamp 6 will produce a small amount of ozone, which will be adsorbed by the honeycomb activated carbon filter. The bottom plate 11 can be opened with an exhaust hole at the contact point between the honeycomb activated carbon filter and the bottom plate 11 to allow the ozone to be discharged. The high-pressure mercury lamp 6 is an auxiliary sterilization light source.

[0024] See some possible implementations. Figure 2 As shown, the adjusting rod assembly includes a fixed threaded tube 12 vertically fixed on the bottom plate 11, and an extension rod 13 with a threaded connection inside the fixed threaded tube 12. In order to meet the disinfection needs of different items, the internal space of the ultraviolet disinfection box is adjusted. During adjustment, the extension rod 13 is rotated to adjust the height of the adjusting rod assembly. Then, a suitable number of assembled boxes 2 are installed on the adjusting rod assembly, so that the space of the ultraviolet disinfection box meets the needs of the items to be disinfected.

[0025] See some possible implementations. Figure 3 and Figure 4 As shown, the assembled box 2 includes a square frame 21, a shelf 7 located inside the square frame 21 and detachably connected to the inner wall of the square frame 21, an embedded edge 22 extending from the bottom of the square frame 21, an embedded groove 23 that mates with the embedded edge 22 on the upper surface of the square frame 21, two adjacent square frames 21 are connected to the embedded groove 23 through the embedded edge 22, a bottom groove is provided on the bottom plate 11, and the bottommost square frame 21 is connected to the bottom groove through its bottom embedded edge 22.

[0026] In the above scheme, when installing the ultraviolet disinfection box, multiple prefabricated boxes 2 are sequentially fitted onto multiple fixed threaded tubes 12 and extension rods 13, such that between two adjacent prefabricated boxes 2, the embedding edge 22 of the upper prefabricated box 2 is embedded in the embedding groove 23 of the lower prefabricated box 2, and the two adjacent prefabricated boxes 2 can be magnetically connected. The embedding edge 22 of the bottommost prefabricated box 2 is embedded in the bottom groove on the bottom plate 11, and the bottommost prefabricated box 2 and the bottom plate 11 can be magnetically connected.

[0027] See some possible implementations. Figures 3 to 5As shown, the top cover 3 and the square frame 21 are respectively provided with a first socket 9 and a second socket 25 on the same side bottom. The top ultraviolet lamp panel 10 is electrically connected to the first socket 9, the middle ultraviolet lamp panel 8 is electrically connected to the second socket 25, the bottom plate 11 and the square frame 21 are respectively provided with a first socket and a second socket 24 on the same side upper surface, the bottom of the lowest square frame 21 is electrically connected to the first socket, and two adjacent square frames 21 are electrically connected to each other through the second socket 24 and the second socket 25.

[0028] In the above scheme, by setting the first socket 9, the second socket 25, the first socket and the second socket 24, when the assembled box 2 is installed on multiple fixed threaded tubes 12 and extension rods 13 and the embedded edge 22 is inserted into the embedded groove 23 of the assembled box 2 below, the middle ultraviolet lamp panels 8 on the adjacent assembled box 2 are connected in parallel, then the top ultraviolet lamp panel 10 is connected in parallel with the uppermost middle ultraviolet lamp panel 8, and finally the whole is connected in parallel with the bottom ultraviolet lamp panel 5 on the bottom plate 11.

[0029] See some possible implementations. Figure 1 and Figure 2 As shown, a wire 4 is provided on one side of the bottom plate 11. The wire 4 is electrically connected to the bottom ultraviolet lamp plate 5 and the first socket respectively. Multiple high-pressure mercury lamps 6 are connected in parallel and electrically connected to the wire 4. The wire 4 is electrically connected to the first socket, so that the wire 4 is electrically connected to the top ultraviolet lamp plate 10, the middle ultraviolet lamp plate 8, and the bottom ultraviolet lamp plate 5 after being connected in parallel, and then connected to an external power source.

[0030] See some possible implementations. Figure 3 and Figure 4 As shown, the shelf 7 has elastic connecting pieces at both ends. The inner side of the square frame 21 has a slot that matches the elastic connecting piece. The elastic connecting piece engages with the adjacent slot, which facilitates the disassembly and installation of the shelf 7, and makes it easier to clean and replace the shelf 7.

[0031] In some possible implementations, an infrared human body sensor, a light intensity sensor, and a controller are installed on the top of the top cover 3. The infrared human body sensor monitors human activity in the vicinity of the ultraviolet disinfection box in real time. When human activity is detected within 0.5m, an electrical signal is transmitted to the controller, which then controls the power supply to turn off. When no human activity is detected within 0.5m, the controller controls the power supply to turn on. The light intensity sensor uses a dedicated ultraviolet photodiode (response wavelength 200-300nm), paired with a 265±5nm filter, and outputs 0-5V analog voltage. The signal (proportional to illuminance) has a measurement accuracy of ±5%. Illuminance data inside the chamber is collected in real time. The light intensity sensor feeds back illuminance data every 0.5 seconds. If the illuminance is ≥333μW / cm², disinfection is performed for the set duration. If the illuminance is <333μW / cm², the LED drive current is increased through the PWM module (maximum 1.2A). If the illuminance is still not up to standard after current adjustment, the duration is automatically extended to ensure that the cumulative irradiation dose is ≥20000μW・s / cm² (the prior art is directly cited here, and this application does not describe the structure in detail).
