Description

Technical Field

[0001] The invention relates to the field of ultraviolet disinfection, and in particular to a deep ultraviolet LED disinfection device. Background Art

[0002] Deep ultraviolet LED disinfection devices are commonly used for disinfection of water sources, air and surfaces. There are two ways to use deep ultraviolet LED devices for air disinfection. One is to expose the ultraviolet lamp directly indoors to disinfect the indoor air. This method requires workers to stay away from the ultraviolet irradiation area to avoid skin injury. The other is to use it in ventilation ducts. The air is disinfected when the gas flows through the ultraviolet lamp and is finally discharged from the room. In tents used for first aid of injured people outdoors, the air needs to maintain a low bacterial or even sterile environment to avoid wound infection of the injured. In order for the ultraviolet lamp to disinfect the air without affecting the injured, the ultraviolet lamp needs to be covered by a mask to prevent ultraviolet light from radiating to the human body. When the ultraviolet lamp is used for a long time in the mask, the ultraviolet lamp is easy to adhere to dust, which affects the divergence of the light source, and then the disinfection effect gradually deteriorates. The existing ultraviolet lamp is difficult to clean because it is covered by the shell, which increases the difficulty of cleaning the ultraviolet lamp. At the same time, part of the shell is fixed by bolts, and professional tools are required for the disassembly of the shell, which further increases the difficulty of cleaning the ultraviolet lamp.

[0003] At the same time, in the first aid tent, some medical equipment needs to be stored in a sterile environment before use. At the same time, after the use of the medical equipment, it needs to be disinfected. The existing disinfection equipment needs to occupy the ground area, which reduces the movable space in the tent. At the same time, the disinfection equipment needs to be placed far away so as not to affect the recuperation of the injured. At this time, it is extremely inconvenient to take and store the medical equipment in the disinfection equipment, and the medical equipment cannot be provided to medical staff in the first time. Summary of the invention

[0004] In order to overcome the increased difficulty in cleaning existing ultraviolet lamps, the fact that some shells are fixed by bolts makes it more difficult to clean the ultraviolet lamp tubes, and at the same time, in the environment of the first aid tent, the disinfection equipment needs to occupy ground area and cannot provide medical equipment to medical staff in the first time, the present invention provides a deep ultraviolet LED disinfection device.

[0005] The technical solution is: a deep ultraviolet LED disinfection device, including a ventilation box, a cover plate, a hook, a rotary wheel and an ultraviolet lamp; the ventilation box is rotatably connected to the cover plate; a plurality of hooks are arranged on the ventilation box; two rotary wheels are connected inside the ventilation box; a plurality of ultraviolet lamps are arranged between the two rotary wheels; it also includes a baffle, a storage component and a protection system; a plurality of ultraviolet lamps are slidably connected to a plurality of baffles that allow air to be stored in the ultraviolet lamp irradiation area; a hole is opened on each baffle, and the holes on all the baffles are staggered; a storage component for disinfecting and storing medical instruments is arranged in the ventilation box; a protection system for preventing ultraviolet lamps from irradiating medical staff is connected in the ventilation box.

[0006] As an improvement of the above-mentioned scheme, the storage assembly includes a fixed ring, a slider and a storage box; two fixed rings are fixedly connected in the ventilation box; each fixed ring is rotatably connected to the adjacent rotating wheel; each fixed ring is slidably connected to a number of sliders; two sliders located on the same horizontal line on the two fixed rings are jointly fixed to a storage box for placing medical instruments that need to be sterilized.

[0007] As an improvement of the above solution, a glass plate is also included; a glass plate is fixedly connected to the lower sides of several storage boxes to prevent the outside air from directly contacting the medical instruments; the glass plate is made of high-light-transmittance glass.

[0008] As an improvement of the above solution, it also includes rubber strips; each storage box is fixed with a plurality of rubber strips suitable for clamping different medical instruments.

[0009] As an improvement of the above solution, each baffle can slide left and right on a plurality of ultraviolet lamps.

[0010] As an improvement to the above solution, each rubber strip can be slidably adjusted in the storage box.

[0011] As an improvement on the above scheme, the protection system includes a pull rope, a shield and a curved plate; a pull rope is slidably connected to the opposite sides of the two fixed rings; an curved plate is commonly fixedly connected to the opposite sides of the two fixed rings; a shield is slidably connected inside the curved plate through a spring to prevent the ultraviolet lamp from directly irradiating the medical staff; one end of the two pull ropes is fixedly connected to the shield, and the other ends of the two pull ropes pass through the ventilation box and are located outside.

[0012] As an improvement of the above scheme, it also includes an insert plate; the two pull ropes are fixed together with an insert plate to prevent the medical staff from being exposed to ultraviolet rays due to the failure of the shield to be unfolded; the insert plate passes through the lower side of the ventilation box and is embedded in the cover plate.

[0013] As an improvement of the above scheme, it also includes a collecting box and a one-way membrane; a plurality of suction ports are provided on the concave surface of the arc plate; a one-way membrane is fixedly connected to each suction port; the one-way membrane is opened downward; a debris discharge port is provided on the convex surface of the arc plate, and the debris discharge port is connected to each suction port; a collecting box for collecting dust is fixedly connected to the lower side of the ventilation box; clean water is initially stored in the collecting box; and the upper side of the collecting box is connected to the debris discharge port.

[0015] The beneficial effects are as follows: the invention realizes that the ultraviolet lamp inside the ventilation box can be easily cleaned after the cover plate is opened, and at the same time, the rotating wheel enables the ultraviolet lamp to rotate in the ventilation box, making the cleaning of the ultraviolet lamp more convenient;

[0016] By setting multiple baffles in the irradiation area of ​​the ultraviolet lamp, the flow of air is slowed down, and the air is accumulated between two adjacent baffles, which prolongs the disinfection time of the ultraviolet lamp on the air and improves the disinfection effect of the device on the air;

[0017] By placing medical instruments in the storage box, the medical instruments can be disinfected and kept sterile at all times. At the same time, the medical instruments can be put away immediately after being picked up, making full use of the disinfection ability of ultraviolet lamps, making it more convenient and quick for medical staff to take medical instruments.

[0018] The shield is unfolded and matched with the curved plate to form a cylindrical shape, thereby covering the ultraviolet lamp, so that the light source emitted by the ultraviolet lamp cannot pass through the shield and the curved plate to irradiate the medical staff, thereby avoiding harm to the medical staff;

[0019] The plug plate is embedded in the cover plate at this time, so that the medical staff cannot open the cover plate. At this time, the medical staff needs to pull the pull rope to drive the plug plate out of the cover plate to open the cover plate and take out the medical equipment, which further protects the medical staff;

[0020] When the mask is unfolded, the dust is sucked into the collection box, which is convenient for medical staff to clean the curved plate. At the same time, the detachable collection box is convenient for emergency drainage under the front body of the ventilation box without removing it, so as to provide emergency protection for the device.

DETAILED DESCRIPTION

[0030] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-Figure 4 As shown, a deep ultraviolet LED disinfection device includes a ventilation box 1, a cover plate 2, a hook 3, a rotating wheel 4 and an ultraviolet lamp 5; the ventilation box 1 is rotatably connected to the cover plate 2; a plurality of hooks 3 are arranged on the ventilation box 1; two rotating wheels 4 are connected inside the ventilation box 1; a plurality of ultraviolet lamps 5 are arranged between the two rotating wheels 4;

[0033] It also includes a baffle 6, a storage component and a protection system; a number of ultraviolet lamps 5 are slidably connected to a number of baffles 6; each baffle 6 is provided with a hole, and the holes on all the baffles 6 are staggered; a storage component is arranged in the ventilation box 1; and a protection system is connected in the ventilation box 1.

[0034] The storage assembly includes a fixed ring 101, a slider 102 and a storage box 103; two fixed rings 101 are fixedly connected in the ventilation box 1; each fixed ring 101 is rotatably connected to the adjacent rotating wheel 4; each fixed ring 101 is slidably connected to a plurality of sliders 102; two sliders 102 located on the same horizontal line on the two fixed rings 101 are fixedly connected to a storage box 103.

[0035] A glass plate 104 is also included; a glass plate 104 is fixedly connected to the lower side of a plurality of storage boxes 103; the glass plate 104 is made of high light-transmitting glass material.

[0036] It also includes rubber strips 105 ; each storage box 103 has a plurality of rubber strips 105 fixedly connected therein.

[0037] Each baffle 6 can slide left and right on a plurality of ultraviolet lamps 5, so as to facilitate cleaning of the dead angle area between the ultraviolet lamps 5 and the baffle 6. Meanwhile, the mutual contact and collision between two adjacent baffles 6 during the sliding process facilitates shaking off the dust on the baffle 6 itself.

[0038] Each rubber strip 105 can be slidably adjusted in the storage box 103 to adapt to the placement and clamping of different medical instruments, thereby improving the adaptability of the storage box 103 .

[0039] During the use of the ultraviolet lamp 5, since the ultraviolet lamp 5 has a sterilization function, it is suitable for multiple functions such as water source disinfection, air disinfection and object surface disinfection, and there are two ways of air disinfection. One is to directly expose it to the air to disinfect the indoor air, and the other is to be set in a pipe to disinfect the air flowing through it. Since the ultraviolet lamp 5 needs to avoid direct irradiation of the human body, at this time, the ultraviolet lamp 5 is placed in the ventilation box 1, and then the ultraviolet lamp 5 is isolated from the outside world by covering the ventilation box 1. The hook 3 on the ventilation box 1 is placed on the frame in the first aid tent, and any side of the ventilation box 1 is connected to the outside world, while the other side of the ventilation box 1 is connected to the first aid tent. When air enters the ventilation box 1, it passes through the ventilation box 1 disinfects the air indoors and outdoors, and by isolating the ultraviolet lamp 5 in the ventilation box 1, dust accumulated on the surface of the ultraviolet lamp 5 during long-term outdoor use is likely to affect the light source divergence of the ultraviolet lamp 5, thereby affecting the disinfection of the air. In order to avoid this phenomenon, when the ultraviolet lamp 5 that has been used for a long time needs to be maintained and cleaned, the cover 2 is opened to clean the ultraviolet lamp 5. During this process, the wheel 4 is rotatable on the fixed ring 101. While cleaning the ultraviolet lamp 5, the ultraviolet lamp 5 in the ventilation box 1 is turned to the area where the cover 2 is opened by rotating the wheel 4. This facilitates the cleaning of the ultraviolet lamp 5 by medical staff and reduces manual workload.

[0040] It is also considered that, in the process of ultraviolet lamp 5 disinfecting the air, multiple baffles 6 are arranged in the irradiation area of ​​ultraviolet lamp 5. When air passes through baffle 6, the air is blocked by baffle 6 so that the air only flows from the opening of baffle 6 to the next baffle 6, thereby slowing down the flow of air and accumulating air between two adjacent baffles 6, thereby extending the disinfection time of air by ultraviolet lamp 5, improving the disinfection effect of the device on air, and avoiding the rapid circulation of air through ultraviolet lamp 5, resulting in poor disinfection effect. Furthermore, while cleaning the ultraviolet lamp 5, each baffle 6 slides back and forth left and right on the ultraviolet lamp 5 to clean the dead corners where ultraviolet lamp 5 and baffle 6 contact each other. At the same time, the sliding of baffle 6 causes two adjacent baffles 6 to contact and collide with each other, which is convenient for shaking off the dust on the baffle 6 itself, and finally the dust is cleaned and collected by medical staff.

[0041] It is also considered that some medical instruments have high requirements for placement in the emergency tent and need to be stored in an environment with few bacteria or sterile. At the same time, they need to be disinfected before use. In order to facilitate the operation of medical staff, when the medical instruments need to be stored, the medical staff first turns off the ultraviolet lamp 5, then opens the cover 2, and pulls the storage box 103 to slide counterclockwise from right to left, thereby making the slider 102 and the glass plate 104 slide counterclockwise along the fixing ring 101. At this time, the medical staff opens the storage box 103 as shown in FIG. Figure 4 As shown, the medical instruments are placed in the storage box 103, and finally the storage box 103 is covered. The medical instruments are placed in each storage box 103 in the above manner, and then the storage box 103 is pushed back to the initial position, and the light transmittance of the glass plate 104 is used to make the light source emitted by the ultraviolet lamp 5 directly act on the storage box 103, so that the medical instruments are disinfected. Since the lap height of the first aid tent is slightly higher than the height of a normal person, the medical staff can touch the ventilation box 1 with their hands, so that the ventilation box 1 is placed on the frame of the first aid tent, which does not occupy the floor area of ​​the tent, and is also convenient for the medical staff to put the storage box in the process of temporary treatment of the injured. The medical instruments in 103 can be taken out, which is convenient for medical staff to quickly treat the injured. At the same time, the storage box 103 is used to store medical instruments to reduce the setting of storage devices and the medical instruments carried by medical staff. Medical instruments with special storage requirements are placed at the ultraviolet lamp 5 for real-time disinfection, which can be taken and put away at the same time. The disinfection ability of the ultraviolet lamp 5 is utilized to the greatest extent, which makes it more convenient and quick for medical staff to take medical instruments, and at the same time keeps the medical instruments in a sterile state at all times. Furthermore, the addition of the glass plate 104 also avoids direct contact between air and the medical instruments in the storage box 103, avoids air contamination of the medical instruments, and ensures the disinfection effect of the medical instruments.

[0042] Example 2

[0043] On the basis of Example 1, Figure 5 and Figure 6 As shown, the protection system includes a pull rope 201, a cover 203 and a curved plate 204; the opposite sides of the two fixed rings 101 are slidably connected with a pull rope 201; the opposite sides of the two fixed rings 101 are commonly fixed with a curved plate 204; the cover 203 is slidably connected inside the curved plate 204 through a spring; one end of the two pull ropes 201 is fixed with the cover 203, and the other ends of the two pull ropes 201 pass through the ventilation box 1 and are located outside.

[0044] It also includes a plug plate 202; the two pull ropes 201 are fixedly connected to a plug plate 202; the plug plate 202 passes through the lower side of the ventilation box 1 and is embedded in the cover plate 2.

[0045] When medical staff take the medical instruments in the storage box 103, considering that the medical staff may forget to turn off the ultraviolet lamp 5, the medical staff will be exposed to the ultraviolet lamp 5 when opening the cover 2, which may cause the medical staff to be injured. In order to avoid this phenomenon, when the medical staff needs to open the cover 2, they need to pull the pull rope 201 downward first, and then pull the cover 203 to unfold from the curved plate 204, and then cooperate with the curved plate 204 to form a cylindrical shape, and then cover the ultraviolet lamp 5, so that the light source emitted by the ultraviolet lamp 5 cannot pass through the cover 203 and the curved plate 204 to irradiate the medical staff, thereby avoiding harm to the medical staff.

[0046] In order to further prevent the medical staff from opening the cover plate 2 without pulling the drawstring 201, when the medical staff opens the cover plate 2, since the plug plate 202 is embedded in the cover plate 2 when the drawstring 201 is not pulled down, the medical staff cannot open the cover plate 2. At this time, the medical staff needs to pull the drawstring 201 downward to drive the plug plate 202 out of the cover plate 2, and at the same time unfold the shield 203 to cover the ultraviolet lamp 5, and the spring between the shield 203 and the curved plate 204 is stretched. At this time, the medical staff can open the cover 2 to take out the medical equipment. To further protect the medical staff, after the plug plate 202 is pulled out, the medical staff loosens the pull rope 201, so that the spring between the cover 203 and the arc plate 204 is reset to drive the cover 203 to retract to the initial state, and then pulls the pull rope 201 to gradually retract into the ventilation box 1, thereby pulling the plug plate 202 to move upward. When the medical staff loosens the pull rope 201, the medical staff aligns the plug plate 202 with the ventilation box 1 to ensure that the plug plate 202 is reset.

[0047] Example 3

[0048] On the basis of Examples 1 and 2, Figure 1 , Figure 7 and Figure 8As shown, it also includes a collecting box 301 and a one-way membrane 302; a plurality of suction ports 20401 are provided on the concave surface of the arc plate 204; a one-way membrane 302 is fixedly connected to each suction port 20401; the one-way membrane 302 opens downward; a debris discharge port 20402 is provided on the convex surface of the arc plate 204, and the debris discharge port 20402 is connected to each suction port 20401; a collecting box 301 is fixedly connected to the lower side of the ventilation box 1; clean water is initially stored in the collecting box 301; the upper side of the collecting box 301 is connected to the debris discharge port 20402.

[0049] The collection box 301 is located at the lower side of the ventilation box 1 , and the collection box 301 is detachably connected to the ventilation box 1 .

[0050] After the ventilation box 1 has been used for a long time, some dust adhered to the ultraviolet lamp 5 and the baffle 6 is easy to fall and accumulate on the curved plate 204. In order to facilitate the medical staff to clean the curved plate 204, when the medical staff pulls the pull rope 201 to drive the mask 203 to unfold, since the mask 203 is always in contact with the inner wall of the curved plate 204, suction is generated at the suction port 20401 to open the one-way membrane 302 downward, so that the dust accumulated on the curved plate 204 is sucked into the curved plate 204. During the resetting process of the mask 203, the dust is pushed to move toward the exhaust port 20402, so that the dust falls into the collection box 301 through the exhaust port 20402. Clean water is initially stored in the collection box 301, so that dust is mixed into the clean water. When the mask 203 is unfolded next time, the dust mixed into the collection box 301 cannot be drawn back into the arc plate 204 due to the influence of water. At this time, the medical staff removes the collection box 301 from the lower side of the ventilation box 1 to clean the dust in the collection box 301, thereby conveniently completing the cleaning of the arc plate 204. At the same time, the collection box 301 is detachable, so when the ventilation box 1 encounters an extreme rainstorm during use, the collection box 301 is removed to connect the ventilation box 1 to the outside world, and the rainwater accumulated in the ventilation box 1 is urgently discharged without disassembling the front body of the ventilation box 1.

[0051] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
