Description

Technical Field

[0001] The present application relates to the technical field of disinfection equipment, and in particular to a disinfection device. Background Art

[0002] A clean bench provides a localized, dust-free and sterile working environment. It is widely used in research and production departments requiring a clean, sterile working environment, such as those involved in pharmaceuticals, biopharmaceuticals, sterility testing, and microbiological testing. The clean bench has an operating chamber, which is sterilized before experiments or tests are performed. A lift door is installed at the entrance of the chamber. When the clean bench is not in use, the lift door is lowered to prevent microorganisms from entering the chamber.

[0003] Before using the clean bench, turn on the UV light to sterilize the operating chamber with the lift door closed. Then, manually push the lift door upward to open it. Finally, use an alcohol sprayer to disinfect your hands and forearms outside the operating chamber before entering the chamber. Using an alcohol sprayer to disinfect your hands requires first spraying the alcohol with one hand, then switching hands to disinfect the hand that hasn't been sprayed. This makes the entire disinfection process quite inconvenient. Summary of the Invention

The driving column is provided with an extension block, and the extension block is provided with a slot for inserting the snap-in piece. The snap-in piece is provided with a snap-in ball, and the slot wall of the slot is provided with a snap-in groove for the snap-in ball to be engaged. The giveway groove gradually becomes smaller from the groove diameter close to one side of the driving column to the groove diameter on the other side.

[0013] Optionally, the solution box is provided with a support plate for driving the driving column to rise, and the support plate is located at the opening of the clearance groove on the side away from the driving column. The support plate is provided with an arc block for driving the clamping piece to slide in the slot to drive the clamping ball to clamp into the clamping groove.

[0014] Optionally, a paddle is provided on the groove wall of the give way groove close to the driving column side to drive the receiving ball to disengage from the receiving groove, the paddle is rotatably installed on the groove wall of the give way groove, and a return spring is provided in the give way groove to drive the paddle to return to its original position after rotation.

[0015] Optionally, when the driving column enters the clearance groove from the side close to the dial plate, the locking piece drives the dial plate to rotate and make way, and the side of the contact spring close to the anode contact piece is provided with a protrusion that cooperates with the dial plate.

A purple light lamp is installed on the wall of the disinfection chamber, and the outer surface of the base body is made of 316L stainless steel.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The base body will be connected to the clean bench, and the installation cavity will also be connected to the operating cavity on the clean bench. When it is necessary to enter the operating cavity of the clean bench for inspection or experiment, the foot is stepped on to drive the lifting plate to rise, and the solution box will move upward with the lifting plate. When the driving column enters the yield groove, the anode contact piece will contact the cathode contact piece. At this time, the disinfectant liquid in the solution box is sprayed out through the spray head. At the same time, the experimenter puts his hands into the disinfection cavity to spray the disinfectant liquid to the hand position for disinfection. During the disinfection process, it is more convenient to only step on the foot switch with his foot. In addition, during the disinfection process, the hand position does not need to touch other objects, thereby improving the disinfection effect. The disinfection process is carried out in the disinfection cavity, which is separated from the installation cavity by the action of the lifting partition. At the same time, under the action of the ultraviolet lamp, the disinfection cavity is made into a relatively sterile cavity;

[0021] Under the action of the supporting plate, the driving column will make the lifting partition rise and fall together with the lifting plate. When the driving column is on the supporting plate, the driving column will also be completely disengaged from the giving way slot. After the driving column is disengaged from the giving way slot, the clamping piece will be squeezed and moved toward the inside of the slot under the action of the arc block, thereby making the clamping ball clamped into the clamping slot. At this time, the anode contact and the cathode contact are no longer in contact, and the spray head stops spraying, and the staff can enter the installation chamber through the disinfection chamber to work; when the lifting plate descends, since the clamping piece is clamped in the slot, the contact spring does not contact the anode contact when the driving column passes through the giving way slot, and the spray head will not spray and cause waste.

[0022] When the lifting plate is lowered, the driving column disengages from the give way slot. When the driving column moves to the opening of the give way slot away from the supporting plate, the dial plate will enter the dial slot. As the lifting plate continues to descend, the dial plate will drive the card piece to move in the direction away from the slot, thereby causing the card ball to disengage from the card slot, so that the next time the lifting plate rises and the driving column enters the give way slot, the anode contact and the cathode contact can contact so that the spray head can continue to spray disinfectant. After the card ball disengages from the card slot, it automatically disengages from the dial slot under the action of the arc surface of the dial plate as the lifting plate descends, without interfering with it.

Implementation Method

[0034] The following is combined with Figure 1-10 This application is described in further detail.

[0035] The embodiment of the present application discloses a disinfection device.

[0036] Example 1: Reference Figure 1 and Figure 2 The disinfection device includes a disinfection base, a disinfection mechanism, and a disinfection control mechanism. The disinfection mechanism is mounted on the disinfection base and can rotate at any angle on the disinfection base. The disinfection control mechanism controls the disinfection mechanism to perform disinfection. The disinfection mechanism can disinfect by spraying disinfectant, ultraviolet irradiation, radiation disinfection, or microwave disinfection. The disinfection base can be connected to laboratory equipment such as a biological safety cabinet, clean bench, or fume hood. The following description uses the disinfection device connected to a clean bench as an example.

[0037] The disinfection matrix comprises a base body 1, a top seat 2, a lifting plate 3, a lifting partition 4 and a foot switch 6. The preferred disinfection mechanism of the present embodiment is a disinfection spray mechanism 5. The base body 1 has a mounting cavity 11, and the top seat 2 is installed on the top of the mounting cavity 11 cavity mouth. The lifting partition 4 is installed on the top seat 2 along the vertical direction to block the cavity mouth of the mounting cavity 11. The lifting plate 3 is located at a side of the lifting plate 3 away from the cavity bottom of the mounting cavity 11. The lifting plate 3 and the lifting partition 4 are spaced apart, and the chamber spaced between the lifting plate 3 and the lifting partition 4 is set as a disinfection chamber 12. The disinfection spray mechanism 5 is installed on a side of the lifting plate 3 near the lifting partition 4. The foot switch 6 is installed on a side at the bottom of the base body 1 for controlling the rise or decline of the lifting plate 3. The disinfection spray mechanism 5 rises and falls along with the rise and fall of the lifting plate 3. When the lifting plate 3 rises to a certain height, the lifting partition 4 starts to rise. When disinfecting the hands of staff, the staff step on the foot switch 6 to drive the lifting plate 3 to rise, and then put the hands into the disinfection chamber 12 to be disinfected by the disinfection spray mechanism 5.

[0038] In this embodiment, the disinfection control mechanism is preferably a foot switch 17, which is mounted on the base body 1. In other embodiments, the disinfection control mechanism can be any one of infrared sensing, contact sensing, and weight sensing.

[0039] The lifting plate 3 and the lifting partition 4 are both made of transparent materials, so as to facilitate direct observation of the situation inside the installation cavity 11. The outer surface of the base body 1 is made of 316L stainless steel.

[0040] Reference Figure 1 and Figure 2 The base body 1 has two horizontally located walls on either side of the opening of the mounting cavity 11, each with a sliding groove extending vertically. A lead screw motor 13 is mounted within the sliding groove. Sliding blocks inserted into the sliding grooves are fixed to both horizontal ends of the lifting plate 3. The sidewalls of the sliding blocks abut against the walls of the sliding grooves. The screw in the lead screw motor 13 passes through the sliding blocks and is threadedly connected to them. Rotation of the lead screw motor 13 drives the sliding blocks to slide vertically within the sliding grooves.

[0041] A violet lamp 14 is installed on the cavity wall of the installation cavity 11 where the sliding groove is provided. The violet lamp 14 is located in the disinfection cavity 12 , and the violet lamp 14 can sterilize the disinfection cavity 12 .

[0042] Reference Figure 2 and Figure 3A waste liquid collection tank 15 is provided on the wall of the mounting chamber 11 on the ground side. The waste liquid collection tank 15 is located below the top seat 2 and inside the disinfection chamber 12. A filter plate 16 is provided at the notch of the waste liquid collection tank 15. When disinfecting hands, excess disinfectant can pass through the filter plate 16 and enter the waste liquid collection tank 15. In addition, the ultraviolet light 14 can kill bacteria on the surface of the laboratory equipment, providing a high standard of sterile environment.

[0043] The side of the top seat 2 close to the ground is provided with a first lifting slot 21 for the lifting plate 3 to be inserted and slid, and a second lifting slot 22 for the lifting partition 4 to be inserted and slid. A button is provided on the outer wall of the top seat 2, and the forward and reverse rotation of the screw motor 13 can be changed by the button.

[0044] A connecting plate 18 is bolted to the side wall of the base body 1, extending toward the clean bench. The other side of the connecting plate 18 can be bolted to the outer wall of the clean bench, thereby connecting the disinfection device to the clean bench. A sealing strip 19 is also adhered to the side of the base body 1 near the clean bench, ensuring a tight connection between the installation cavity 11 and the operating chamber of the clean bench, preventing airflow from passing through the gap between the installation cavity 11 and the operating chamber of the clean bench.

[0045] Reference Figure 2 and Figure 4 The disinfection spray mechanism 5 includes a solution box 51, a spray head 52, a spray sliding drive assembly 53, a telescopic tube 54 and a rotating disk 55. Disinfectant is contained in the solution box 51, and the solution box 51 is mounted on the lifting plate 3 by sliding in the horizontal direction through the spray sliding drive assembly 53. Since people generally sit in the middle of the opening of the installation cavity 11 when doing experiments, the spray sliding drive assembly 53 will drive the solution box 51 to slide in the horizontal direction when the lifting plate 3 is raised or lowered, so that the experimenter can stay in the middle position without moving, which is convenient for disinfecting the experimenter's hands. One end of the telescopic tube 54 is connected to and communicated with the spray head 52; the other end is connected to the rotating disk 55. The rotating disk 55 is rotatably mounted at the bottom of the receiving box, and the disinfectant in the solution box 51 can flow into the telescopic tube 54. The telescopic tube 54 can be twisted at any angle, so that the spray head 52 can be rotated at any angle and telescopically adjusted. When the lifting plate 3 is raised and the items entering the installation cavity 11 need to be disinfected, the spray head 52 can be raised and lowered through the telescopic tube 54. At the same time, the spray head 52 can be directly moved into the installation cavity 11 to disinfect the table, thereby making disinfection more convenient. Among them, the spray head 52 can achieve a spray particle size of 2-50 μm.

[0046] Reference Figure 4 and Figure 5A fan 56 is mounted on one side of the solution box 51, where the rotating disk 55 is mounted. This prevents the disinfectant from being dispersed by the spray head 52, allowing a larger amount of disinfectant to reach the hands. A foot switch 17 is mounted on the bottom of the base body 1 to control the spraying of disinfectant by the spray head 52. This allows the foot switch 17 to control the spraying of disinfectant when disinfecting laboratory equipment or the interior of the mounting cavity 11.

[0047] The spray sliding drive assembly 53 includes a first fixed pulley 531, a second fixed pulley 532, and a drive wire 533. The first fixed pulley 531 and the second fixed pulley 532 are both rotatably mounted on the side of the lifting plate 3 near the lifting partition 4. The first fixed pulley 531 and the second fixed pulley 532 are spaced apart horizontally. One end of the drive wire 533 passes under the first fixed pulley 531 and is fixed to the top seat 2; the other end of the drive wire 533 passes over the second fixed pulley 532 and is fixed to the cavity wall on the side of the installation cavity 11 close to the ground. The solution box 51 is located between the first fixed pulley 531 and the second fixed pulley 532, and the drive wire 533 is fixed to the solution box 51. Therefore, when the lifting plate 3 rises or falls, the solution box 51 can slide horizontally under the action of the drive wire 533.

[0048] Combine Figure 2 Reference Figure 4 and Figure 5 It is worth noting that when the lifting plate 3 blocks the disinfection chamber 12, the solution box 51 is located on a side close to the second fixed pulley 532. As the lifting plate 3 rises, the solution box 51 will move to a side close to the first fixed pulley 531.

[0049] A drive column 41 is bolted to the side of the lift plate 4 near the lift plate 3. A support plate 57 is fixed to the side of the solution box 51 near the second fixed pulley 532. When the support plate 57 moves with the solution box 51 to the position of the drive column 41, it lifts the drive column 41, driving the lift plate 4 to rise along with the lift plate 3. The bottom of the lift plate 4 is heavier than the top, allowing the lift plate 4 to automatically descend under the action of gravity.

[0050] A clearance groove 511 is defined on the side of the solution box 51 near the drive column 41. Because the solution box 51 slides horizontally as the lifting plate 3 rises, the clearance groove 511 is angled to allow the end of the drive column 41 near the solution box 51 to be inserted and passed through. The clearance groove 511 gradually decreases in size from the side near the drive column 41 to the side near the support plate 57, making it easier for the drive column 41 to enter the clearance groove 511.

[0051] Combine Figure 5 Reference Figure 6 and Figure 7, an anode contact 512 is installed on the groove wall of the yield groove 511 near the spray head 52, and the part of the drive column 41 inserted into the yield groove 511 is installed with a cathode contact 42 that abuts and cooperates with the anode contact 512. Then, during the rising process of the lifting plate 3, the anode contact 512 cooperates with the cathode contact 42 to enable the spray head 52 to spray disinfectant. Since it takes a certain amount of time for the drive column 41 to pass through the yield groove 511, the spray head 52 can also continue to spray for a period of time to completely disinfect the hands. When you want to adjust the time when the spray head 52 sprays disinfectant, you can adjust the speed of the screw motor 13 to change the rising speed of the lifting plate 3, and then change the time when the drive column 41 passes through the yield groove 511.

[0052] Reference Figure 7 The cathode contact 42 includes a contact spring 421 and a snap-on piece 422. The contact spring 421 is tilted and disposed on the drive post 41. The snap-on piece 422 is located at the end of the contact spring 421 away from the drive post 41. The snap-on piece 422 and the contact spring 421 are integrally formed. The snap-on piece 422 extends obliquely away from the anode contact 512. An extension block 43 is integrally formed on the outer wall of the drive post 41. A slot 431 is defined on the side of the extension block 43 proximal to the snap-on piece 422. The portion of the snap-on piece 422 away from the contact spring 421 is inserted into the slot 431.

[0053] A semi-spherical catch ball 4221 is integrally formed on one side of the latching piece 422. A catch groove 4311 is defined on the wall of the slot 431 to engage and limit the catch ball 4221. As the drive post 41 moves within the clearance slot 511, the diameter of the clearance slot 511 decreases, causing the latching piece 422 to move deeper into the slot 431, thereby securing the anode contact 512 more securely.

[0054] Reference Figure 5 and Figure 7 , an arc block 571 is integrally formed on one side of the support plate 57 near the corresponding opening of the clearance groove 511. After the contact spring 421 is separated from the clearance groove 511, it will be squeezed and deformed under the action of the arc block 571, and at this time, the driving clamping piece 422 will be further moved into the slot 431, thereby causing the clamping ball 4221 to be clamped in the clamping groove. When the lifting plate 3 descends and the driving rod enters the clearance groove 511 from the support plate 57, since the clamping ball 4221 is clamped in the clamping groove 4311, the contact spring 421 will not contact the anode spring, and the spray head 52 will not spray disinfectant.

[0055] Combine Figure 5 Reference Figure 6 and Figure 7A selector plate 58 is rotatably mounted on the wall of the opening of the yield groove 511 on the side away from the supporting plate 57. The selector plate 58 is an arc-shaped plate. The selector plate 58 is rotatably mounted on the bottom of the yield groove 511 along its own extension direction through a rotating pin. The lower arc of the selector plate 58 faces the opening of the yield groove 511 on the side close to the supporting plate 57. A return spring 59 is fixed on the top of the arc of the supporting plate 57. The other end of the return spring 59 is fixed to the wall of the yield groove 511 on the side where the anode contact piece 512 is set. Then, when the drive column 41 enters the yield groove 511 from the side where the selector plate 58 is set, the selector plate 58 is squeezed and rotated without interfering with the contact spring piece 421.

[0056] A protrusion 4211 is integrally formed on the side of the contact spring 421 closest to the anode contact 512. A circular surface 4212 is formed on the side of the protrusion 4211 facing away from the contact spring 421. A semi-cylindrical actuating slot 4213 is defined on the circular surface 4212 of the protrusion 4211. When the contact spring 421 moves to the position of the actuating plate 58, the side of the actuating plate 58 closest to the contact spring 421 engages the actuating slot 4213. As the contact spring 421 continues to move, the actuating plate 58 hooks onto the protrusion 4211, thereby disengaging the latching ball 4221 from the latching slot 4311. Because the return spring 59 is located at the top of the arc of the actuating plate 58, the initial slight rotation of the actuating plate 58 after insertion into the actuating slot 4213 as the contact spring 421 moves compresses the return spring 59 to its limit. The arrangement of the arc surface 4212 and the toggle groove 4213 makes it easy for the toggle plate 58 to be removed after insertion and prevents it from getting stuck. This allows the contact spring 421 to abut against the anode contact 512 the next time it enters the clearance groove 511, allowing the spray head 52 to spray normally.

[0057] The implementation principle of a disinfection device in an embodiment of the present application is: when it is necessary to conduct experiments or inspections in the installation cavity 11, the foot switch 6 is stepped on with the foot, and the screw motor 13 will drive the lifting plate 3 to rise; at this time, the solution box 51 will move toward the direction close to the first fixed pulley 531 under the action of the first fixed pulley 531, the second fixed pulley 532 and the driving wire 533.

[0058] When the solution box 51 moves to the position of the drive column 41, the contact spring 421 enters the clearance groove 511 and abuts the anode contact 512. At this time, the spray head 52 will begin to spray disinfectant; the staff member's hand can be inserted into the disinfection chamber 12 for disinfection. When the contact spring 421 disengages from the clearance groove 511 as the lifting plate 3 rises, the drive column 41 falls onto the support plate 57, and the spray head 52 stops spraying. The lifting partition 4 will also rise under the action of the support plate 57 and the drive column 41. The staff member's disinfected hand can enter the installation chamber 11 to conduct experiments.

[0059] After the contact spring 421 is released from the clearance groove 511, it will be squeezed and deformed by the action of the arc block 571, and the driving clamping piece 422 will be moved further into the slot 431, so that the clamping ball 4221 is clamped in the clamping groove. When the lifting plate 3 is lowered and the driving rod enters the clearance groove 511 from the support plate 57, the clamping ball 4221 is clamped in the clamping groove 4311, so that the contact spring 421 will not contact the anode spring, and the spray head 52 will not spray the disinfectant.

[0060] When the contact spring 421 moves to the position of the dial plate 58, the side of the dial plate 58 near the contact spring 421 will be inserted into the dial groove 4213. As the contact spring 421 continues to move, the dial plate 58 will be inserted into the dial groove 4213, thereby driving the latching ball 4221 out of the latching groove 4311, so that the contact spring 421 can abut against the anode contact 512 when it enters the clearance groove 511 next time, allowing the spray head 52 to spray normally.

[0061] Example 2: Combination Figure 2 Reference Figure 8 and Figure 9 The difference between this embodiment and the first embodiment is that the disinfectant spray mechanism 5 includes a solution box 51, a spray head 52, a spray sliding drive assembly 53, a rigid tube 7, a rotating damping ball 8, and a connecting spherical shell 9. One end of the rigid tube 7 is connected to the spray head 52; the other end is connected to the rotating damping ball 8. The side of the rotating damping ball 8 facing away from the rigid tube 7 is provided with a solution tank 81 that is connected to the rigid tube 7. The connecting spherical shell 9 is mounted on one side at the bottom of the solution box 51 and universally connected to the rotating damping ball 8 on the other side. The side of the rotating damping ball 8 with the solution tank 81 is inserted into the connecting spherical shell 9 and can be universally rotated. A certain damping force is generated between the rotating damping ball 8 and the connecting spherical shell 9. Therefore, after being rotated by a staff member, the rotating damping ball 8 can be stopped at any angle to adjust the spray angle. The disinfectant in the solution box 51 can flow from the connecting spherical shell 9 into the solution tank 81. The disinfectant then passes through the rigid tube 7 and is sprayed out through the spray head 52.

[0062] Example 3: Reference Figure 2 and Figure 10The difference between this embodiment and the first embodiment is that the disinfectant spray mechanism 5 includes a solution box 51, a spray head 52, a spray sliding drive assembly 53, a rotating ring 10, a connecting pipe 101, a hose 102, and a damping rotating bracket 103. The rotating ring 10 is rotatably mounted on the bottom of the solution box 51. The connecting pipe 101 is a stainless steel pipe and is fixedly connected to the rotating ring 10. The connecting pipe 101 extends to the side away from the bottom of the solution box 51; the connecting pipe 101 rotates synchronously with the rotating ring 10, wherein the connecting pipe 101 is connected to the solution box 51. One end of the hose 102 is connected to the side of the connecting pipe 101 facing away from the solution box 51; the other end is connected to the spray head 52, so that the disinfectant in the connecting pipe 101 can pass through the hose 102 and be sprayed out through the spray head 52. The damping rotating bracket includes a damping rotating rod 1031 and a sleeve ring 1032. The damping rotating rod 1031 is located on one side of the sleeve ring 1032; the damping rotating rod 1031 and the sleeve ring 1032 are integrally formed. A damping rotating shaft 1011 is provided on the outer wall of the connecting tube 101. The damping rotating rod 1031 is rotated and mounted on the damping rotating shaft 1011, and the sleeve ring 1032 is sleeved onto the hose 102. When the damping rotating rod 1031 rotates, the hose 102 bends under the action of the sleeve ring 1032, changing the spray direction of the spray head 52. Simultaneously, the rotating ring 1032 can rotate the spray head 52 360 degrees. Furthermore, a certain damping force is generated between the damping rotating rod 1031 and the damping rotating shaft 1011. Therefore, after the operator applies force to rotate the rotating bracket, the sleeve ring 1032 can be positioned at any angle to adjust the spray angle.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
