Description

Technical Field

[0001] The present invention belongs to the technical field of medical ultraviolet sterilization equipment, and particularly relates to an ultraviolet disinfection and sterilization device. Background Art

[0002] Medical ultraviolet sterilization equipment is a device that uses ultraviolet radiation to eliminate pathogenic microorganisms. Its principle is that ultraviolet light can damage the DNA or RNA structure of microorganisms, causing them to be unable to replicate and reproduce, thereby achieving the sterilization effect. This kind of equipment is usually used for sterilization work in environments such as hospitals, laboratories, and clinics, such as disinfecting instruments, and is widely used to reduce the spread of bacteria, viruses, and fungi, ensuring the hygienic safety of the medical environment.

[0003] Chinese Patent with application number 202010473937.6 discloses an ultraviolet irradiation device for disinfection in traditional Chinese medicine hospitals, including a disinfection cabinet, a cabinet door, and a moving mechanism. The back of the disinfection cabinet is slidably connected with a mounting plate through a track, and both sides of the bottom of the mounting plate are slidably connected with movable blocks through guide rails. One side of the movable block away from the mounting plate is fixedly connected with a translation mechanism, and the back of the translation mechanism is slidably connected with the back of the inner wall of the disinfection cabinet through a track. For this ultraviolet irradiation device for disinfection in traditional Chinese medicine hospitals, by slidably connecting movable blocks on both sides of the bottom of the mounting plate, and fixedly connecting a translation mechanism to one side of the movable block away from the mounting plate, setting a first ultraviolet irradiation lamp inside the disinfection cabinet and a second ultraviolet irradiation lamp on the back of the disinfection cabinet, it can disinfect medical instruments and can also disinfect indoor areas such as operating rooms. The operation is simple and more convenient to use.

[0004] When disinfecting medical instruments with ultraviolet sterilization equipment, usually the instruments are placed in the disinfection chamber, and then after disinfection, the ultraviolet lamp is turned off and the cabinet is opened for the next batch of disinfection work. In scenarios such as surgical operating rooms, the disinfection is more frequent. Such frequent switching operations are troublesome and require constantly turning on and off the ultraviolet lamp equipment, resulting in low aging life of the ultraviolet lamp equipment; at the same time, for new unused instruments and used instruments, the sterilization requirements in the two situations are completely different. If not effectively handled, it will further lead to the problem of low sterilization efficiency; and how to improve the sterilization effect is also an important research direction. Summary of the Invention

[0005] To address the deficiencies of the prior art, the present invention provides an ultraviolet disinfection and sterilization device. Through the structural design of the receiving disc top box, the instrument cylinder, and the receiving disc, the present invention can achieve continuous and uninterrupted disinfection operations without frequent cabinet opening operations. This not only avoids the low efficiency caused by frequent cabinet opening but also prevents the problem of low aging life due to frequent switching on and off of the ultraviolet lamp. Through the cooperation of the control mechanism and the receiving disc, the present invention can not only achieve continuous shallow disinfection but also quickly switch to deep disinfection to meet different disinfection and sterilization requirements, and the switching process maintains uninterrupted disinfection operations. Through the cooperation of the ultraviolet lamp module with the control mechanism and the receiving disc, the present invention can achieve rapid and deep dead-end disinfection operations.

[0009] A cross groove is provided on the receiving disc. A sliding groove opening is penetrated through the inner groove of the four sides of the cross groove. An instrument cylinder is slidably connected to the sliding groove opening. A first toothed ring is fixedly provided on the outer side of the instrument cylinder. When the material opening is aligned with the instrument cylinder, the instrument cylinder is located at the outer end of the sliding groove opening.

[0010] Further, a control mechanism is installed at the bottom of the receiving disc. The control mechanism includes a chassis. A plurality of hinge grooves are uniformly fixedly provided around the top of the chassis. One end of the link is hinged to the hinge groove. The other end of the link is hinged to a T-shaped block. The T-shaped block is rotatably connected to the middle of the bottom of the instrument cylinder.

[0011] A through hole is penetrated through the middle of the chassis. An electric telescopic rod is fixedly connected to the inside of the support member. The end of the electric telescopic rod is fixedly connected to a pull rod. One end of the pull rod passes through the support member, and the annular groove at the end of the pull rod is rotatably connected to the through hole. A second toothed ring is fixedly provided on the outside of the support member. When the second toothed ring meshes with the first toothed ring, the instrument cylinder is located at the inner end of the sliding groove opening.

[0012] Even further, a T-shaped groove is fixedly provided at the center of the bottom of the instrument cylinder. A T-shaped block is rotatably connected to the T-shaped groove. One end of the T-shaped block is fixedly provided with a second hinge groove. The second hinge groove is hinged to one end of the link.

[0013] Furthermore, an inner ring groove is formed in the side wall of the sliding notch, and an outer ring block is fixedly arranged outside the T-shaped groove. The outer ring block is located in the inner ring groove and is slidably connected with the inner ring groove.

[0014] Further, the support member includes a square groove. The top end of the square groove is fixedly connected to the center of the inner top of the top box, and the electric telescopic rod is located in the square groove; a gear is fixedly connected to the bottom end of the square groove, and the outer side of the gear is a second toothed ring; a sleeve and a limiting disc are fixedly connected to the bottom end of the gear in sequence. A second through hole is formed through the middle of the limiting disc; a rotating hole is formed through the center of the bottom of the cross groove, and the rotating hole is rotatably connected with the sleeve; the pull rod passes through the second through hole, the sleeve and the middle of the gear in sequence.

[0015] Further, an outer toothed ring is fixedly arranged outside the receiving disc, a driving motor is fixedly installed inside the bottom box, and a second gear at the output end of the driving motor meshes with the outer toothed ring.

[0016] Further, the ultraviolet lamp module includes a pair of mounting plates, and a plurality of ultraviolet lamps are fixedly installed at the bottom of the mounting plates; a sliding rod is fixedly connected to the top of the mounting plates. A pair of sliding holes are formed in the top of the sterilization box. The sliding rod passes through the corresponding sliding holes and the ends of the sliding rods are fixedly connected together through a control board; a return spring is sleeved on the sliding rod between the control board and the top of the sterilization box.

[0017] Further, a light absorbing plate is also fixedly arranged inside the bottom box.

[0018] Further, hanging buckles are fixedly arranged around the outside of the bottom groove, locking buckles are fixedly arranged corresponding to the outside of the bottom box around the outside, and the locking buckles are locked corresponding to the hanging buckles; a control panel is fixedly arranged outside the sterilization box.

[0019] A method for disinfection and sterilization using the above ultraviolet disinfection and sterilization device includes the following steps:

[0020] S1. When shallow disinfection is required, the driving motor drives the receiving disc to rotate to make the instrument cylinders rotate. When an instrument cylinder passes below one of the material ports, instruments are sequentially placed in it. When passing below the ultraviolet lamp on the way, the instruments are sequentially sterilized.

[0021] S2. After disinfection is completed, when the multiple instrument cylinders rotate to below the other material port in sequence, the instruments are taken out, thereby realizing continuous shallow disinfection.

[0022] S3. When deep disinfection is required, the instrument cylinder passes under one of the material ports and the instruments are sequentially placed in it. Then, the electric telescopic rod extends to push the pull rod, and the instrument cylinder is pulled by the connecting rod to slide to the inner end of the sliding slot opening. At this time, the instrument cylinder is located inside the sterilization box, and the second gear ring meshes with the first gear ring. When the receiving disc rotates, it not only drives the instrument cylinder to rotate around, but also the instrument cylinder is limited by the second gear ring to cause the instrument cylinder to rotate itself, thereby achieving continuous sterilization and disinfection without dead angles. And press the control panel to lower the mounting plate and the ultraviolet lamp and irradiate the instruments at a close distance.

[0023] S4. After disinfection is completed, release the control panel. The electric telescopic rod contracts to pull the pull rod, so that the instrument cylinder slides to the outer end of the sliding slot opening, and then the instruments can be taken out from the material port in sequence to achieve deep disinfection.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) Through the structural design of the receiving disc top box, the instrument cylinder and the receiving disc, the present invention can achieve continuous and uninterrupted disinfection operations without frequently opening the cabinet door. While avoiding the low efficiency caused by frequent opening of the cabinet door, it also prevents the problem of low aging life caused by frequent opening and closing of the ultraviolet lamp. Specifically, when shallow disinfection is required, the receiving disc is controlled to rotate by external power. When the instrument cylinder passes under one of the material ports, the instruments are sequentially placed in it. On the way, the instruments are sequentially sterilized and disinfected when passing under the ultraviolet lamp. After disinfection is completed, the multiple instrument cylinders are sequentially rotated to the lower part of another material port to take out the instruments, so that continuous shallow disinfection can be achieved without interruption. Continuous and uninterrupted disinfection operations can be achieved without frequently opening the cabinet door. While avoiding the low efficiency caused by frequent opening of the cabinet door, it also prevents the problem of low aging life caused by frequent opening and closing of the ultraviolet lamp.

[0026] (2) Through the cooperation of the control mechanism and the receiving disc, the present invention can not only achieve continuous shallow disinfection, but also quickly switch to deep disinfection to meet different sterilization and disinfection requirements, and the disinfection operation remains uninterrupted throughout the switching process. Specifically, when shallow disinfection is required, the electric telescopic rod of the control mechanism pulls the pull rod, and at this time, the chassis moves upward. During the upward movement, due to the hinge of the connecting rod, the connecting rod pushes the instrument cylinder to slide towards the outer end of the sliding groove opening. When the instrument cylinder reaches the outer end of the sliding groove opening, the rotation of the receiving disc will cause the multiple instrument cylinders to rotate circumferentially to achieve subsequent continuous shallow disinfection. When deep disinfection is required, when the instrument cylinder passes under one of the material ports, the instruments are sequentially placed in it, and then the electric telescopic rod extends to push the pull rod, and the instrument cylinder is pulled by the connecting rod to slide to the inner end of the sliding groove opening. At this time, the instrument cylinder is located inside the sterilization box, and the second gear ring meshes with the first gear ring. When the receiving disc rotates, it not only drives the instrument cylinder to rotate circumferentially, but also the instrument cylinder is limited by the second gear ring to cause the instrument cylinder to rotate self - sufficiently to achieve dead - angle - free continuous sterilization and disinfection. At this time, the rotation of the receiving disc can no longer align the material port with the instrument cylinder, and the instruments in the instrument cylinder will always be in the state of being irradiated by ultraviolet light. Through the cooperation of the ultraviolet lamp module, it can quickly switch to deep disinfection to meet different sterilization and disinfection requirements. And whether it is shallow disinfection or deep disinfection, it can achieve quick sample placing and sampling only through the control mechanism without stopping the machine, so as to realize uninterrupted sterilization and disinfection operation throughout the switching process.

[0027] (3) Through the cooperation of the ultraviolet lamp module with the control mechanism and the receiving disc, the present invention realizes quick deep dead - angle - free disinfection operation. Specifically, when deep disinfection is required, through the control of the control mechanism, it can not only make the multiple instrument cylinders rotate circumferentially while making the instrument cylinder rotate self - sufficiently to achieve dead - angle - free continuous sterilization and disinfection, and at this time, hold down the control panel to make the mounting plate and the ultraviolet lamp descend and irradiate the instruments at a short distance. Through the combination of the circumferential rotation and self - rotation of the instrument cylinder and the quick short - distance irradiation of the ultraviolet lamp, it realizes quick deep dead - angle - free disinfection operation.

[0042] Although the steps in the present invention are arranged with reference numerals, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It can be understood that the term "and / or" used herein relates to and encompasses any and all possible combinations of one or more of the associated listed items.

[0043] Embodiment

[0044] As Figures 1 to 11 shown, an ultraviolet disinfection and sterilization device includes a bottom box 100. The top of the bottom box 100 is plugged, fixedly connected and communicated with a top box 200. An ultraviolet lamp module 300 is installed on the inner top of the top box 200. A support member 800 is fixedly connected to the center of the inner top of the top box 200. A receiving disc 400 is rotatably connected to the bottom of the support member 800.

[0045] The top box 200 includes a bottom groove 210. The middle of the top of the bottom groove 210 is fixedly communicated with a sterilization box 230. Both sides of the top of the bottom groove 210 are fixedly communicated with material grooves 220. The material grooves 220 are communicated with the sterilization box 230, and a material opening 221 is provided at the top of the material grooves 220. The receiving disc 400 is in contact with the two material grooves 220.

[0046] A cross groove 420 is provided on the receiving disc 400. A sliding groove opening 430 is penetrated through the inner groove of the periphery of the cross groove 420. An instrument cylinder 600 is slidably connected to the sliding groove opening 430. A first tooth ring 610 is fixedly provided on the outer side of the instrument cylinder 600. When the material opening 221 is aligned with the instrument cylinder 600, the instrument cylinder 600 is located at the outer end of the sliding groove opening 430.

[0047] Through the structural design of the receiving disc top box 200, the instrument cylinder 600 and the receiving disc 400, the present invention can achieve continuous and uninterrupted disinfection operation without frequent cabinet opening operations. While avoiding the low efficiency caused by frequent cabinet opening, it also prevents the problem of low aging life caused by frequent switching on and off of the ultraviolet lamp. Specifically, when shallow disinfection is required, the receiving disc 400 rotates under the control of external power. When the instrument cylinder 600 passes under one of the material ports 221, instruments are sequentially placed into it. During the process, the instruments are sequentially sterilized and disinfected when passing under the ultraviolet lamp 320. After disinfection is completed, when multiple instrument cylinders 600 rotate to the other material port 221 in sequence, the instruments are taken out, so as to achieve continuous shallow disinfection without interruption. Continuous and uninterrupted disinfection operation can be achieved without frequent cabinet opening operations. While avoiding the low efficiency caused by frequent cabinet opening, it also prevents the problem of low aging life caused by frequent switching on and off of the ultraviolet lamp.

[0048] Further, a control mechanism 700 is installed at the bottom of the receiving disc 400. The control mechanism 700 includes a chassis 730. A plurality of hinge grooves 731 are evenly and fixedly arranged around the top of the chassis 730; one end of a connecting rod 740 is hinged to the hinge groove 731, and the other end of the connecting rod 740 is hinged to a T-shaped block 750. The T-shaped block 750 is rotatably connected to the middle of the bottom of the instrument cylinder 600.

[0049] A through hole 732 is formed through the middle of the chassis 730; an electric telescopic rod 710 is fixedly connected inside the support member 800. The end of the electric telescopic rod 710 is fixedly connected to a pull rod 720. One end of the pull rod 720 passes through the support member 800 and the annular groove 721 at the end of the pull rod 720 is rotatably connected to the through hole 732; a second toothed ring 820 is fixedly arranged on the outside of the support member 800. When the second toothed ring 820 meshes with the first toothed ring 610, the instrument cylinder 600 is located at the inner end of the sliding slot opening 430.

[0050] The present invention can realize continuous shallow disinfection and quick switching for deep disinfection through the cooperation of the control mechanism 700 and the receiving disc 400, so as to meet different sterilization and disinfection requirements, and maintain uninterrupted disinfection operation during the switching process; specifically, when shallow disinfection is required, the pull rod 710 is pulled by the electric telescopic rod 710 of the control mechanism 700, and the chassis 730 moves up at this time; during the upward movement, due to the hinge of the connecting rod 740, the connecting rod 740 pushes the instrument barrel 600 to slide toward the outer end of the sliding groove 430; when the instrument barrel 600 reaches the outer end of the sliding groove 430, the rotation of the receiving disc 400 at this time causes multiple instrument barrels 600 to rotate circumferentially, thereby realizing subsequent continuous shallow disinfection; when deep disinfection is required, the instrument barrel 600 puts the instruments in one by one when passing under one of the material ports 221, and then the electric telescopic rod 710 extends to push the pull rod 720 , the instrument barrel 600 is pulled to slide to the inner end of the sliding groove 430 through the connecting rod 740. At this time, the instrument barrel 600 is located inside the sterilization box 230, and the second gear ring 820 is meshed with the first gear ring 610; when the receiving disc 400 rotates, it not only drives the instrument barrel 600 to rotate, but also the instrument barrel 600 is limited by the second gear ring 820 to make the instrument barrel 600 rotate, thereby realizing continuous sterilization and disinfection without dead angles; at this time, the rotation of the receiving disc 400 can no longer align the material port 221 with the instrument barrel 600, and the instrument in the instrument barrel 600 will always be in a state of being irradiated by ultraviolet rays. Through the cooperation of the ultraviolet lamp module 300, it can quickly switch to deep disinfection, thereby meeting different sterilization and disinfection requirements; and whether it is continuous shallow disinfection or deep disinfection, it only needs to use the control mechanism 700 to realize rapid sample placement and sampling without stopping, thereby realizing uninterrupted sterilization and disinfection operations throughout the switching process.

[0051] It is worth mentioning that when deep disinfection is performed, since the support member 800 is fixed at the inner top center of the top box 200, the support member 800 and the second gear ring 820 are fixed when the receiving disc 400 rotates. At this time, if the instrument barrel 600 rotates and engages with the second gear ring 820, then under the limitation of the second gear ring 820, the instrument barrel 600 will rotate on its own.

[0052] Furthermore, a T-slot 620 is fixedly provided at the bottom center of the instrument cylinder 600 , and a T-block 750 is rotatably connected to the T-slot 620 . A second hinge slot 751 is fixedly provided at one end of the T-block 750 , and the second hinge slot 751 is hinged to one end of the connecting rod 740 .

[0053] Through the design of the T-slot 620 and the T-block 750, the sliding and self-rotation of the instrument cylinder 600 do not interfere with each other. When sliding, the T-slot 620 and the instrument cylinder 600 are driven to slide by the pushing and pulling action of the connecting rod 740. When rotating, the T-slot 620 and the T-block 750 at the bottom of the instrument cylinder 600 rotate relative to each other.

[0054] Furthermore, an inner ring groove 431 is formed in the side wall of the sliding notch 430, and an outer ring block 621 is fixedly arranged outside the T-slot 620. The outer ring block 621 is located in the inner ring groove 431 and is slidably connected with the inner ring groove 431.

[0055] Through the structural design of the outer ring block 621 and the inner ring groove 431, the instrument cylinder 600 slides directionally in the inner ring groove 431.

[0056] Further, the support member 800 includes a square groove 810. The top end of the square groove 810 is fixedly connected to the center of the inner top of the top box 200, and the electric telescopic rod 710 is located in the square groove 810. The bottom end of the square groove 810 is fixedly connected with a gear, and the outside of the gear is a second tooth ring 820. The bottom end of the gear is fixedly connected with a sleeve 830 and a limit disc 840 in sequence. A second through hole 850 is formed through the middle of the limit disc 840. A rotating hole 440 is formed through the center of the bottom of the cross groove 420, and the rotating hole 440 is rotatably connected with the sleeve 830. The pull rod 720 passes through the second through hole 850, the sleeve 830 and the middle of the gear in sequence.

[0057] Through the fixing effect of the square groove 810, the gear, the sleeve 830 and the limit disc 840, the receiving disc 400 can be supported; through the structural design of the pull rod 720 and the electric telescopic rod 710, the vertical displacement of the chassis 730 can be conveniently controlled, so as to control the sliding of the receiving disc 400; through the structural design of the annular groove 721 at the end of the pull rod 720, the problem that the pull rod 720 is stuck when the receiving disc 400 and the connecting rod 740 rotate together is avoided.

[0058] Further, an outer tooth ring 410 is fixedly arranged outside the receiving disc 400, and a transmission motor 500 is fixedly installed inside the bottom box 100. A second gear 510 at the output end of the transmission motor 500 meshes with the outer tooth ring 410.

[0059] The rotation of the receiving disc 400 is controlled by the transmission motor 500, and at the same time, the transmission ratio is conveniently controlled through this transmission method, so as to effectively control the time when the instrument cylinder 600 passes under the ultraviolet lamp for sterilization during shallow disinfection, thereby realizing effective disinfection.

[0060] Further, the ultraviolet lamp module 300 includes a pair of mounting plates 310, and a plurality of ultraviolet lamps 320 are fixedly installed at the bottom of the mounting plates 310; a sliding rod 330 is fixedly connected to the top of the mounting plates 310, and a pair of sliding holes 231 are formed in the top of the sterilization box 230. The sliding rod 330 passes through the corresponding sliding holes 231 and the ends of the sliding rod 330 are fixedly connected together through a control board 350; a return spring 340 is sleeved on the sliding rod 330 between the control board 350 and the top of the sterilization box 230.

[0061] Through the cooperation of the ultraviolet lamp module 300 with the control mechanism 700 and the receiving disc 400, the present invention realizes rapid deep and dead-angle-free disinfection operation; specifically, when deep disinfection is required, through the control of the control mechanism 700, the plurality of instrument cylinders 600 can be rotated circumferentially and the instrument cylinders 600 can be rotated self-rotationally at the same time to realize continuous sterilization and disinfection without dead angles. And at this time, hold down the control board 350 to lower the mounting plate 310 and the ultraviolet lamp 320 and irradiate the instruments at a short distance. Through the combination of the circumferential rotation and self-rotation of the instrument cylinder 600 and the rapid short-distance irradiation of the ultraviolet lamp 320, the rapid deep and dead-angle-free disinfection operation is realized.

[0062] Further, a light absorption plate 910 is also fixedly provided inside the bottom box 100.

[0063] The light absorption plate 910 prevents the exposure of ultraviolet rays from causing harm. The light absorption plate can be made of carbon materials, etc., which is a conventional technology in the art and will not be described in detail here.

[0064] Further, hanging hooks 211 are fixedly provided on the outer periphery of the bottom groove 210, and locking buckles 110 are fixedly provided on the outer periphery of the bottom box 100 corresponding to the hanging hooks 211, and the locking buckles 110 are locked corresponding to the hanging hooks 211; a control panel 232 is fixedly provided on the outer side of the sterilization box 230.

[0065] The locking buckle 110 and the hanging hook 211 facilitate the rapid disassembly of the device, which is beneficial to subsequent maintenance; the control panel 232 is used to control power equipment such as the transmission motor 500, the ultraviolet lamp 320, and the electric telescopic rod 710. At the same time, the power equipment in this application is powered by an external power supply, which will not be described in detail here.

[0066] A method for disinfecting and sterilizing using the above ultraviolet disinfection and sterilization device includes the following steps:

[0067] S1. When shallow disinfection is required, the transmission motor 500 drives the receiving disc 400 to rotate to make the instrument cylinder 600 rotate circumferentially. When the instrument cylinder 600 passes under one of the material ports 221, the instruments are sequentially placed in it. When passing under the ultraviolet lamp 320 on the way, the instruments are sequentially sterilized and disinfected;

[0068] S2. After disinfection is completed, when multiple instrument cylinders 600 are successively rotated to be under another material port 221, take out the instruments, so as to achieve continuous shallow disinfection;

[0069] S3. When deep disinfection is required, when the instrument cylinder 600 passes under one of the material ports 221, put the instruments in successively, then the electric telescopic rod 710 extends to push the pull rod 720, and the instrument cylinder 600 is pulled to slide to the inner end of the sliding slot 430 through the connecting rod 740. At this time, the instrument cylinder 600 is located inside the sterilization box 230, and the second gear ring 820 meshes with the first gear ring 610; when the receiving disc 400 rotates, it not only drives the instrument cylinder 600 to rotate around, but also the instrument cylinder 600 is limited by the second gear ring 820 to make the instrument cylinder 600 rotate self - so as to achieve dead - angle - free continuous sterilization and disinfection; and press the control board 350 to make the mounting board 310 and the ultraviolet lamp 320 descend and irradiate the instruments at a close distance;

[0070] S4.
