Description

Technical Field

[0001] This disclosure relates to the field of sterilization and disinfection devices, and in particular to an ultraviolet-ozone synergistic sterilization and disinfection device. Background Technology

[0002] The biomedical engineering industry involves instruments or tools that require sterilization before use. Common methods include ultraviolet (UV) sterilization and ozone sterilization. UV sterilization utilizes ultraviolet light with wavelengths in the 240-280nm range, which is most effective at destroying the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses, causing cell death during growth and / or regeneration, thus achieving sterilization. Ozone can oxidize and decompose the enzymes required for glucose production inside bacteria, inactivating and killing the bacteria. It can also directly interact with bacteria and viruses, damaging their organelles and DNA / RNA, disrupting bacterial metabolism and leading to bacterial death. Ozone can penetrate cell membranes and invade the cell, acting on lipoproteins on the outer membrane and lipopolysaccharides inside, causing permeability distortion and lysis. For existing technologies, the drawback of ultraviolet sterilization is that there are some blind spots that cannot be irradiated by ultraviolet light, while the drawback of ozone sterilization is that ozone needs to be discharged after sterilization, which affects the efficiency of sterilization of biomedical instruments and tools.

[0015] The technical solution provided in this disclosure may include the following beneficial effects: This invention drives a motor to rotate a first gear that meshes with an internal gear ring, causing two vertical frames to rotate. At the same time, a first screw inside one of the vertical frames rotates, so that the ultraviolet lamp ring and the first screw move up and down along the inside of the vertical frame while rotating in a circle, so that the items in the middle area are fully irradiated with ultraviolet light, ensuring the comprehensiveness of the sterilization and disinfection process. After disinfection and sterilization are completed, the ozone supply is stopped. The two extended ends of the first bidirectional electric push rod are separated from the clamping plate. The second spring, which is connected to the top of the insertion tube and the vertical rod, drives the insertion tube and the first valve plate to move upward, connecting the first connecting tube to the inside of the disinfection box. The high-speed airflow is drawn into the disinfection box from one side of the first connecting tube by the air intake fan and then discharged from the other side of the first connecting tube, so as to quickly empty the ozone inside the disinfection box. This invention seals the inlet and outlet of the disinfection box by lowering the sealing plate, preventing the leakage of ultraviolet light and ozone during the disinfection process. Simultaneously, as the vertical frame moves downward, the first toothed plate meshes with the second gear, causing the second gear to rotate and drive the second toothed plate upward along the guide frame. At this time, because the extended end of the first bidirectional electric push rod on the first valve plate is locked with the two locking plates, the first valve plate and the insertion tube will not move upward. Only the vertical rod inside the insertion tube moves upward with the second toothed plate. Simultaneously, the second connecting frame drives the inclined block upward, and the first spring moves the horizontal bar outward, separating the second valve plate from the second valve seat, connecting the ozone generating device to the inside of the disinfection box. At the same time, the seal between the first valve plate and the first valve seat isolates the disinfection box from the outside world. Ozone is injected into the disinfection box through the ozone generating device, working in conjunction with the ultraviolet light for sterilization and disinfection. This invention controls the installation plate to move outward via a second bidirectional electric push rod. The insert plate pulls the horizontal frame and the fixed plate to move to both sides of the disinfection box. Furthermore, the drive motor on the rotating shaft of the fixed plate and the rotating plate controls the folding of the rotating plate and the fixed plate together to facilitate the passage of objects. After the objects enter the disinfection box, the conveyor belt stops moving, and the two sealing doors close the inlet and outlet of the disinfection box. The drive motor opens the rotating plate to form a right-angle plate with the fixed plate. The bidirectional electric push rod pushes the fixed plates and the rotating plate on both sides to move towards the center. At the same time, the second bidirectional screw in the horizontal frame rotates, bringing together the right-angle plate composed of the four fixed plates and the rotating plate, concentrating the items in the middle area of ​​the disinfection box, which facilitates subsequent ultraviolet lamp ring irradiation for sterilization.

Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the figure, this disclosure proposes an ultraviolet-ozone synergistic sterilization and disinfection device, including: a conveyor table 1, a disinfection box 2 fixed at the top center of the conveyor table 1, an inlet and outlet provided on the front and back of the disinfection box 2, and a sealing door 21 slidably inserted into the top of the inlet and outlet of the disinfection box 2, an inlet / outlet air box 3 fixed at the top of the disinfection box 2, a first connecting pipe 31 fixed on both sides of the bottom of the inlet / outlet air box 3, and the bottom of the first connecting pipe 31 fixedly connected to both sides of the disinfection box 2, a switching component 5 provided between the disinfection box 2 and the inlet / outlet air box 3, and positioning components 6 provided at the four corners inside the disinfection box 2; the vertical tube of the first connecting pipe 31... A first valve seat 59 is fixed, and a first valve plate 511 is sealed and inserted into the middle of the first valve seat 59. An ozone generating device 32 is fixed on one side of the outer wall of the disinfection box 2, located on the first connecting pipe 31. A second connecting pipe 33 is fixed on the surface of the ozone generating device 32, and the other end of the second connecting pipe 33 is fixedly connected to the bottom of the first connecting pipe 31. A second valve seat 519 is fixed inside the horizontal tube of the second connecting pipe 33, and a second valve plate 518 is sealed and inserted into the middle of the second valve seat 519. The switching assembly 5 includes a vertical frame 52, which is provided with the top of the disinfection box 2, and the bottom ends of the vertical frame 52 are connected to two sealing doors. 21. Fixed connection: A tube 58 is fixed to the top of the first valve plate 511, and a crossbar 516 is fixed to the center of the second valve plate 518. The crossbar 516 and the tube 58 are connected to the vertical frame 52 via a transmission connection. The positioning assembly 6 includes a fixing plate 64. Four fixing plates 64 are provided at the four corners inside the disinfection box 2, and a rotating plate 65 is rotatably mounted on one end of each fixing plate 64. An electric motor is installed at the pivot of the fixing plate 64 and the rotating plate 65. Horizontal frames 66 are provided at the bottom of both sides of the disinfection box 2. Two fixing plates 64 on the same side inside the disinfection box 2 slide along the inside of the horizontal frames 66. When using the device, the parts to be disinfected and sterilized are placed in the horizontal frame 66. The biological hospital-specific instruments or tools being processed are placed on the conveyor 1 and fed into the disinfection chamber 2. The positioning component 6 moves the object to the middle position of the disinfection chamber 2. The switching component 5 first seals the inlet and outlet of the disinfection chamber 2 and the first connecting pipe 31. Ozone is then introduced into the disinfection chamber 2 through the ozone generating device 32. The ultraviolet lamp ring 27 and ozone are sterilized and disinfected in the sealed environment inside the disinfection chamber 2. After disinfection, the first connecting pipe 31 is opened to quickly discharge the ozone inside the disinfection chamber 2. Finally, the sealing door 21 is opened and the object is sent out of the disinfection chamber 2 through the conveyor 1, maintaining the high efficiency of the entire disinfection process.

[0020] like Figure 2 , Figure 3 and Figure 8As shown, in some embodiments, the disinfection box 2 has air vents 22 on both sides, an air intake fan 23 is fixed to the outer wall of one side of the disinfection box 2 and is fixedly connected to the first connecting pipe 31, and the other side of the disinfection box 2 is fixedly connected to the first connecting pipe 31; wherein, an internal gear ring 26 is rotatably installed on the top of the disinfection box 2, vertical frames 28 are fixed on both sides of the bottom of the internal gear ring 26, ultraviolet lamp rings 27 are slidably installed on the inner rings of the two vertical frames 28, a first gear 25 is meshed with one side of the internal gear ring 26, and a drive motor 24 is fixed to the top of the disinfection box 2, and the output end of the drive motor 24 is fixedly connected to the first gear 25; wherein, a first screw 29 is rotatably installed inside the vertical frame 28 on one side of the disinfection box 2, and the mounting frame of the ultraviolet lamp ring 27 is meshed with the first screw 29, and a motor that drives the first screw 29 to rotate is installed inside the vertical frame 28.

[0021] Understandably, the drive motor 24 drives the first gear 25 to rotate and mesh with the internal gear ring 26, which in turn drives the two vertical frames 28 to rotate. At the same time, the first screw 29 inside one of the vertical frames 28 rotates, so that the ultraviolet lamp ring 27 and the first screw 29 move up and down along the inside of the vertical frame 28 while rotating in a circle, so that the items in the middle area are fully irradiated with ultraviolet light, ensuring the comprehensiveness of the sterilization and disinfection treatment.

[0022] like Figure 1 and Figure 3 As shown, in some embodiments, the conveyor 1 is symmetrically provided with two limiting plates 4 on the top surface of the inlet and outlet ends of the disinfection box 2, and the two limiting plates 4 on the same side of the conveyor 1 are fixed with a first connecting frame 41; wherein, a first bidirectional screw 42 is rotatably installed on the top of the inlet end of the disinfection box 2, and the two first connecting frames 41 are threadedly sleeved on both ends of the first bidirectional screw 42, and a motor for driving the first bidirectional screw 42 to rotate is installed on one end of the disinfection box 2 corresponding to one end of the first bidirectional screw 42.

[0023] Understandably, by driving the first bidirectional screw 42 to rotate via the motor, the first connecting frame 41 on both sides drives the limiting plates 4 on both sides of the conveyor 1 to move towards the middle of the conveyor 1, thereby limiting the conveying of items before and after entering the disinfection box 2.

[0024] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the switching assembly 5 further includes: a second screw 51, a horizontal plate 53, a first toothed plate 54, and a second gear 55. The second screw 51 is rotatably mounted on the back of the disinfection box 2 and the air inlet / outlet box 3. The top of the vertical frame 52 is threaded onto the surface of the second screw 51. The top of the vertical frame 52 is fixed with the horizontal plate 53 facing the first connecting pipes 31 on both sides. The outermost end of the horizontal plate 53 is fixed with the first toothed plate 54. The first connecting pipe 31 is rotatably mounted on one side of the first toothed plate 54. The device is equipped with a second gear 55, and the first gear plate 54 is meshed with the second gear 55. The air inlet / outlet box 3 is located on top of the second screw 51 and is equipped with a motor that drives the second screw 51 to rotate. A second gear plate 56 is meshed with the other side of the second gear 55. A vertical rod 520 is slidably inserted into the inside of the insertion tube 58, and the top of the vertical rod 520 and the insertion tube 58 slidably protrude from the top of the first connecting tube 31. The top of the vertical rod 520 is fixedly connected to the second gear plate 56. The vertical rod 520 protrudes from the insertion tube. A second spring 521 is sleeved on the top of the first valve plate 511, and the two ends of the second spring 521 are fixedly connected to the second toothed plate 56 and the insertion tube 58, respectively. A first bidirectional electric push rod 512 is fixed on the top of the first valve plate 511. A retaining plate 510 is fixed on the two ends of the first bidirectional electric push rod 512 corresponding to the first valve seat 59, and the two extended ends of the first bidirectional electric push rod 512 are inserted into the retaining plate 510. A guide frame 57 is fixed on the outer wall of the first connecting tube 31 corresponding to the movement path of the second toothed plate 56, and the second toothed plate 56 is fixed to the second toothed plate 56. 56 slides along the guide frame 57. One end of the crossbar 516 that extends out of the second connecting pipe 33 is fixed with an inclined plate 515. The bottom of the second toothed plate 56 is fixed with a second connecting frame 513. One end of the second connecting frame 513 corresponding to the inclined plate 515 is fixed with an inclined block 514. The inclined block 514 slides along the inclined surface of the inclined plate 515. The end of the crossbar 516 that extends out of the second connecting pipe 33 is sleeved with a first spring 517. The two ends of the first spring 517 are fixedly connected to the inclined plate 515 and the second connecting pipe 33, respectively.

[0025] It should be noted that the switching component 5 enables the disinfection box 2 to operate in three states. First, the motor drives the second screw 51 to rotate, causing the vertical frame 52 to move upwards, which in turn moves the two sets of sealing doors 21 upwards, opening the inlet and outlet of the disinfection box 2 to facilitate the entry of items for disinfection. Then, the second screw 51 rotates in the opposite direction, causing the sealing plate to descend and seal the inlet and outlet of the disinfection box 2, preventing the leakage of ultraviolet light and ozone during disinfection. Simultaneously, as the vertical frame 52 moves downwards, the first toothed plate 54 meshes with the second gear 55, causing the second gear 55 to rotate and drive the second toothed plate 56 upwards along the guide frame 57. At this point, because the extended end of the first bidirectional electric push rod 512 on the first valve plate 511 is engaged and locked with the two locking plates 510, the first valve plate 511 and the insertion tube 58 will not move upwards. Only the vertical rod 520 inside the insertion tube 58 moves upwards with the second toothed plate 56. Simultaneously, the second connecting frame 513 drives the inclined block 514 upwards, and the first spring 517 moves the horizontal bar 516 outwards. The ozone generator 32 is connected to the disinfection chamber 2 by separating the second valve plate 518 from the second valve seat 519. At the same time, the ozone generator 32 injects ozone into the disinfection chamber 2 and works in conjunction with the ultraviolet light to sterilize. After sterilization, the ozone supply is stopped, and the two extended ends of the first bidirectional electric push rod 512 are separated from the clamping plate 510. The second spring 521, which is connected to the top of the insertion tube 58 and the vertical rod 520, moves the insertion tube 58 and the first valve plate 511 upward, connecting the first connecting pipe 31 to the inside of the disinfection chamber 2. The high-speed airflow is drawn into the disinfection chamber 2 through the fan 23 from one side of the first connecting pipe 31 and then discharged from the other side of the first connecting pipe 31, quickly emptying the ozone inside the disinfection chamber 2. The discharged ozone does not directly enter the air, but is sent to a distant place or introduced into the water through the air inlet / outlet box 3 and additional pipes.

[0026] like Figure 9 and Figure 10 As shown, in some embodiments, the positioning component 6 further includes: a insert plate 63 and a second bidirectional screw 67. The second bidirectional screw 67 is rotatably installed inside the horizontal frame 66, and the fixing plate 64 is threaded onto the surface of the second bidirectional screw 67. Two insert plates 63 are symmetrically fixed on the back of the horizontal frame 66, and the insert plates 63 slide out of the disinfection box 2. A motor for driving the second bidirectional screw 67 to rotate is installed inside one end of the horizontal frame 66. Two second bidirectional electric push rods 61 are symmetrically fixed at the bottom of the disinfection box 2, and the extended end of the second bidirectional electric push rod 61 is fixed with a mounting plate 62. One end of the insert plate 63 is fixedly connected to the mounting plate 62.

[0027] It should be noted that before the items enter the disinfection chamber 2, the mounting plate 62 is moved outward by the second bidirectional electric push rod 61, and the insert plate 63 pulls the horizontal frame 66 and the fixing plate 64 to move to both sides of the disinfection chamber 2. Furthermore, the drive motor on the rotating shaft of the fixing plate 64 and the rotating plate 65 controls the rotating plate 65 to fold together with the fixing plate 64, facilitating the passage of items. After the items enter the disinfection chamber 2, the conveyor belt 1 stops moving, and the two sealing doors 21 close the inlet and outlet of the disinfection chamber 2. The drive motor then moves the rotating plate... The plate 65 opens to form a right-angle plate with the fixed plate 64. The fixed plate 64 and the rotating plate 65 on both sides are pushed to move towards the middle by the bidirectional electric push rod. At the same time, the second bidirectional screw 67 in the horizontal frame 66 rotates, bringing together the right-angle plate formed by the four sets of fixed plates 64 and rotating plates 65, and concentrating the items in the middle area of ​​the disinfection box 2, so as to facilitate the subsequent sterilization and disinfection by the ultraviolet lamp ring 27. When disinfection is performed, the fixed plate 64 and the rotating plate 65 need to be reset and moved away from the middle area so as not to interfere with the movement and rotation of the ultraviolet lamp ring 27.

[0028] Working principle: When using the device, place the special biological hospital instruments or tools that need to be disinfected on the conveyor table 1. The first bidirectional screw 42 is driven by the motor to rotate, and the first connecting frames 41 on both sides drive the limiting plates 4 on both sides of the conveyor table 1 to move towards the middle of the conveyor table 1, limiting the conveying of items before and after entering the disinfection box 2. The items are then conveyed into the disinfection box 2 through the conveyor table 1. Before the items enter the disinfection box 2, the mounting plate 62 is moved outward by the second bidirectional electric push rod 61. The insert plate 63 pulls the horizontal frame 66 and the fixing plate 64 to move towards both sides of the disinfection box 2. The drive motor on the rotating shaft of the fixing plate 64 and the rotating plate 65 controls the rotating plate 65 to merge and fold together to facilitate the passage of items. After the items enter the disinfection box 2... The conveyor belt 1 stops moving, and the two sealing doors 21 close the inlet and outlet of the disinfection box 2. The drive motor opens the rotating plate 65 to form a right-angle plate with the fixed plate 64. The two-way electric push rod pushes the fixed plates 64 and rotating plates 65 on both sides to move towards the middle. At the same time, the second two-way screw 67 in the horizontal frame 66 rotates, bringing together the right-angle plate formed by the four sets of fixed plates 64 and rotating plates 65, concentrating the items in the middle area of ​​the disinfection box 2, which is convenient for subsequent sterilization by the ultraviolet lamp ring 27. During disinfection, the fixed plates 64 and rotating plates 65 need to be reset and moved away from the middle area so as not to interfere with the movement and rotation of the ultraviolet lamp ring 27. The drive motor 24 drives the first gear 25 to rotate and mesh with the internal gear ring 26, which drives the two vertical frames 28. As the UV lamp ring 27 rotates, the first screw 29 inside the vertical frame 28 on one side also rotates, causing the UV lamp ring 27 to move up and down along the inside of the vertical frame 28 while rotating in a circle. This provides comprehensive UV light irradiation to items in the central area, ensuring thorough sterilization and disinfection. The switching component 5 enables the disinfection box 2 to operate in three states. First, the motor drives the second screw 51 to rotate, causing the vertical frame 52 to move upwards along with the second screw 51, which in turn moves the two sets of sealing doors 21 upwards, opening the inlet and outlet of the disinfection box 2 to facilitate the entry of items for disinfection. Subsequently, the second screw 51 rotates in the opposite direction, causing the sealing plate to descend and seal the inlet and outlet of the disinfection box 2, preventing the leakage of UV light and ozone during the disinfection process. Simultaneously, the vertical frame 52 moves downwards... The first toothed plate 54 meshes with the second gear 55, causing the second gear 55 to rotate and drive the second toothed plate 56 to move upward along the guide frame 57. At this time, because the extended end of the first bidirectional electric push rod 512 on the first valve plate 511 is inserted and locked with the two locking plates 510, the first valve plate 511 and the insertion tube 58 will not move upward. Only the vertical rod 520 inside the insertion tube 58 moves upward with the second toothed plate 56. At the same time, the second connecting frame 513 drives the inclined block 514 to move upward, and the first spring 517 moves the horizontal bar 516 outward, separating the second valve plate 518 from the second valve seat 519, connecting the ozone generating device 32 with the interior of the disinfection box 2. At the same time, because of the seal between the first valve plate 511 and the first valve seat 59, the disinfection box 2 is isolated from the outside.Ozone is injected into the disinfection chamber 2 by the ozone generating device 32, simultaneously working with ultraviolet light for sterilization. After sterilization, the ozone supply is stopped, and the two extended ends of the first bidirectional electric push rod 512 separate from the clamping plate 510. A second spring 521, connected to the top of the insertion tube 58 and the vertical rod 520, moves the insertion tube 58 and the first valve plate 511 upwards, connecting the first connecting pipe 31 to the inside of the disinfection chamber 2. The fan 23 draws high-speed air into the disinfection chamber 2 through one side of the first connecting pipe 31 and then discharges it through the other side, quickly emptying the ozone from the disinfection chamber 2. The discharged ozone does not directly enter the air but is sent to a distant location or introduced into water through the inlet / outlet air chamber 3 and additional pipes. Finally, the sealing door 21 is opened, and the object is sent out of the disinfection chamber 2 via the conveyor table 1, maintaining the high efficiency of the entire disinfection process.
