Description

Technical Field

[0001] The present invention relates to the field of medical devices, and specifically to a disinfection and sterilization treatment device for protective clothing. Background Art

[0002] Medical protective clothing is used to isolate germs, harmful ultrafine dust, acid-base solutions, electromagnetic radiation, etc., to ensure the safety of personnel and maintain environmental cleanliness; in recent years, the demand for medical protective clothing has been large, and the demand is greater than the supply, resulting in front-line medical staff not being provided with safety protection, or the scarcity of protective clothing. Medical staff drink less water and use the toilet less during work in order to save protective clothing because many existing brands of protective clothing are disposable and need to be used sparingly. This has caused front-line medical staff to suffer from high-intensity work pressure and physical pain. Moreover, some people infected with respiratory diseases also need to wear protective clothing. Due to the scarcity of protective clothing, patients cannot get protective clothing, leading to the spread of the virus.

[0003] Therefore, people have invented reusable medical protective clothing. For example, the reusable medical protective clothing produced in the MaFang Industrial Park in Pinggu District, Beijing can be reused 10 times after disinfection and sterilization. It will solve the problems of large consumption of disposable medical protective clothing, long production cycle, inconvenient large-scale storage, etc., and reduce the cost of medical waste treatment; however, the disinfection and sterilization process of this reusable protective clothing is a relatively cumbersome process. It is necessary to spread out the soft protective clothing evenly and then disinfect and sterilize each surface. This treatment method has low efficiency and fails to meet the needs of front-line workers.

[0004] Therefore, a disinfection and sterilization treatment device for protective clothing is proposed to solve the above problems. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems mentioned in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A disinfection and sterilization treatment device for protective clothing according to the present invention includes an operating table. The widths of the side plates of the operating table are smaller than the width of the middle plate area. A chute is provided in the length direction of the operating table. A lead screw is rotatably connected in the chute. A slider is drivingly connected to the lead screw. A support rod is vertically fixed to the upper end surface of the slider. A mold in the shape of a human body is fixed to the end of the support rod. A protective clothing is sleeved on the mold; an arc-shaped plate is provided in the middle area of the operating table. The inside of the arc-shaped plate is hollow. A plurality of nozzles are provided on the inner surface of the arc-shaped plate. A plurality of nozzles are also provided in the middle area of the operating table; the end of the lead screw is connected to the output end of a motor, and the forward and reverse rotation of the motor is used to realize the reciprocating movement of the slider in the chute; the inside of the arc-shaped plate is hollow, and the inside of the arc-shaped plate is communicated with an external liquid supply pump. The liquid supply pump injects the disinfected and sterilized liquid into the arc-shaped plate, and then sprays it out from the nozzles on the arc-shaped plate; the nozzles on the operating table are also communicated with the external liquid supply pump, and the nozzles spray the disinfected and sterilized liquid; the operator sleeved the used protective clothing on the mold, and then through the rotation of the lead screw, the slider drives the mold to move through the support rod, bringing the protective clothing under the arc-shaped plate. At the same time, driven by the liquid supply pump, the liquid impacts on the protective clothing to realize the disinfection and sterilization treatment of the protective clothing; because the mold is in the shape of a human body and the protective clothing is sleeved on the mold, the soft protective clothing is supported and opened, and the wrinkled parts on the surface of the protective clothing are also flattened. Then it moves under the arc-shaped plate, and the liquid sprayed by the nozzles can fully cover the surface of the protective clothing, fully disinfecting and sterilizing the protective clothing. At the same time, the efficiency is high. When sleeved on the mold, the automatic cleaning treatment of the protective clothing can be realized, which can meet the needs of the front line.

[0007] Preferably, the support rod includes a movable rod and a fixed rod; the fixed rod is fixed to the slider, a jack is provided at the end of the fixed rod, the movable rod is inserted into the jack, and the end of the movable rod is fixed to the mold; during operation, the operator can be beside the operating table. First, sleeve the protective clothing on the mold, and then when the slider moves to one end position of the operating table, insert the movable rod into the jack on the fixed rod. At this time, the mold can be quickly installed on the slider; sleeve the protective clothing on the mold that is not installed on the operating table in advance, and then install the mold on the slider to make preparations in advance, and there is no need to wait until the mold moves to one end of the operating table, then remove the protective clothing on the mold and then sleeve the protective clothing again, which can improve the efficiency; at the same time, one person stands on both sides of each end of the operating table, and two people at the diagonal positions of the operating table cooperate. One person installs the mold, and the other person removes the mold. At the same time, during the removal process, the person on the opposite side installs the mold, and the two cooperate with each other to improve the efficiency again.

[0008] Preferably, the interior of the mold is hollow, and the mold includes a head, a torso, and limbs; the head is fixedly connected to the movable rod, the head is fixedly connected to the torso, the limbs are connected to the torso by springs, the limbs are connected to the interior of the torso through hoses, and air holes are provided on the surfaces of the head, torso, and limbs; the movable rod and the fixed rod are axially penetrated, the movable rod communicates with the interior of the head, the movable rod communicates with the fixed rod, the insertion hole inside the fixed rod communicates with the air duct opened at the solid part inside the slider, and the air duct communicates with the external air supply pump through a pipe body; the air duct communicates with the external air pump through a pipeline, the air pump injects ozone sterilization gas into the air duct, and then the ozone sequentially passes along the insertion hole and the inside of the movable rod and is injected into the mold. Then, the ozone is discharged from the air holes on the head, torso, and limbs and impacts on the inner surface of the protective clothing. First, it disinfects the inner surface of the protective clothing to improve the cleanliness of the protective clothing. Second, the ozone gas impacts inside the protective clothing to expand the protective clothing, so that the part of the mold that fails to extend to the expanded part inside the protective clothing can also be supported and bulged, which helps the nozzle to spray disinfectant liquid for treating the protective clothing.

[0009] Preferably, the limb includes a fixed cylinder and an extension cylinder; the extension cylinder is slidably connected to the inside of the extension cylinder through a tension spring, an air inlet is provided at the inner end of the extension cylinder, and air holes are provided on the surfaces of the extension cylinder and the fixed cylinder; when the ozone gas is not injected into the mold, the extension cylinder is placed inside the fixed cylinder through the tension spring. At this time, the overall volume of the mold is small, which is convenient for sleeving the protective clothing on the mold. After the ozone gas is injected, the gas impacts on the inner end of the extension cylinder, gradually pushing the extension cylinder out of the fixed cylinder. The ozone gas is ejected from the air holes, and the ozone gas supports the protective clothing. After the protective clothing is disinfected by the liquid sprayed from the nozzle, the ozone gas is no longer supplied. At this time, the extension cylinder returns under the pulling force of the tension spring, and the overall volume of the mold decreases, which helps to take off the protective clothing from the mold, facilitates the operation of the operator, and helps to improve the disinfection and sterilization efficiency.

[0010] Preferably, a sealing ball connected by a spring is provided at the inner bottom of the jack. Above the sealing ball, there is an annular body. The outer circle of the annular body is hermetically fixed to the inner side wall of the jack, and the sealing ball is located inside the inner circle of the annular body. Above the annular body, there is a T-shaped rod connected by a spring. The lower end of the T-shaped rod abuts against the sealing ball. When the mold is not installed on the slider, the protective suit is sleeved on the mold. At this time, the extension cylinder is placed inside the fixed cylinder. After the protective suit is properly sleeved, first, the nozzle of an external air pump is inserted into the movable rod, and gas is injected into the mold. Then, the gas sprays out from the air holes, and at the same time, the extension cylinder extends outwards, propping open the protective suit. That is, first, the protective suit is propped open, and the wrinkled or bent parts of the protective suit rope are unfolded. After the mold is installed on the slider later, ozone gas is injected. At this time, the protective suit can be smoothly unfolded. The setting of the T-shaped rod and the sealing ball is such that after the movable rod is inserted into the jack, under the elastic force of the spring and the pressure of the anode ozone gas, the sealing ball blocks the ozone. After the mold is installed on the slider, that is, when the movable rod is inserted into the jack, the lower end of the movable rod presses down the T-shaped rod, and the T-shaped rod pushes down the sealing ball, opening the inner circle of the annular body. At this time, ozone gas is injected into the movable rod, filling the mold with ozone gas. The setting of the sealing ball is to save ozone gas to prevent ozone gas from continuously spraying out from the jack when the mold is not installed on the slider, causing waste of ozone gas.

[0011] Preferably, a cavity is formed inside the middle area of the operating table, and multiple rotating grooves are formed on the surface of the middle area of the operating table. The rotating grooves communicate with the cavity. The outer ring of the nozzle is connected to the inner side wall of the rotating groove by a conical spring. The nozzles are arranged in rows. The nozzles in the same row are evenly divided into groups by a sliding groove. The nozzles in a group are all connected to a gas supply pipe. One end of the gas supply pipe penetrates to the outside of the operating table and is rotatably connected to the inside of the side wall of the operating table by a torsion spring. The other end of the gas supply pipe is closed. A strip-shaped through hole is formed on the inner side wall of the sliding groove. The other end of the gas supply pipe penetrates the through hole and protrudes from the inner side wall of the sliding groove. When the slider moves in the sliding groove, the side wall of the slider intermittently presses the other end of the gas supply pipe. Then, the gas supply pipe swings towards the slider in the through hole. At the same time, the gas supply pipe drives the nozzle to swing. The nozzle pulls the conical spring and tilts, so that the disinfection and sterilization liquid sprayed out of the nozzle impacts and discharges at a certain angle. In the case where there are wrinkles on the surface of the protective suit, the liquid can also be sprayed into the wrinkle gaps, improving the disinfection and sterilization effect on the protective suit.

[0012] Preferably, the other end of the air supply pipe is rotatably connected to the wheel body up and down; a notch is formed on the outer ring of the through hole, and the height of the notch is greater than the height of the upper and lower wheel bodies; the slider presses the air supply pipe, and the air supply pipe swings in the cavity. After the slider disengages from the air supply pipe, the air supply pipe automatically resets under the torsion of the torsion spring. Moreover, if the slider presses the air supply pipe multiple times and causes wear to the air supply pipe, it will lead to wear and cracking at the other end of the air supply pipe, and at the same time, it will also cause wear to the side wall of the slider. Therefore, the wheel body is provided. Each time the slider presses the air supply pipe, the slider rubs the wheel body to rotate, avoiding direct contact and wear with the other end of the air supply pipe. The air supply pipe swings towards the through hole side, and at the same time, the wheel body is pressed in the notch, and the outer ring of the wheel body is flush with the inner side wall of the chute, and the slider smoothly disengages from the wheel body. After that, the air supply pipe automatically resets under the torsion spring to prepare for the next swing.

[0013] Preferably, the nozzles on the operation table are divided into the first area nozzles, the second area nozzles, and the third area nozzles. The second area nozzles are located between the first area nozzles and the third area nozzles, and the air supply pipes connected to the first area nozzles and the third area nozzles are arranged in two paths; the second area nozzles are opposite to the arc plate, and the first area nozzles and the third area nozzles are located on both sides of the arc plate in the vertical direction; the air supply pipes are arranged in two paths, one path is connected to the external pump body for supplying dry hot air, and the other path is connected to the external pump body for supplying liquid for disinfection and sterilization; when the mold moves from the first area nozzles to the third area nozzles, the first area nozzles and the second area nozzles spray the disinfection and sterilization liquid. When the mold moves to the position of the third area nozzles, the air supply pipe connected to the third area nozzles injects dry hot air flow inside to dry the protective clothing; when the mold moves from the third area nozzles to the first area nozzles, the third area nozzles and the second area nozzles spray the disinfection and sterilization liquid. When the mold moves to the position of the first area nozzles, the air supply pipe connected to the first area nozzles injects dry hot air flow inside to dry the protective clothing; drying the wet protective clothing in advance is helpful for the drying and finishing of the protective clothing when it is taken off later.

[0014] Preferably, a positioning rod is fixedly connected to one side of the lower end of the movable rod, and the positioning rod is inserted into the positioning hole formed on one side of the upper end surface of the fixed rod; by setting the positioning rod, after the fixed rod is inserted into the jack, the positioning rod is inserted into the positioning hole to restrict the rotational constraint between the fixed rod and the movable rod, ensuring that the mold can stably move along the chute to the lower part of the arc plate, preventing the mold from rotating in the horizontal direction, and the edge position of the mold touches the nozzle, which hinders the spraying of the liquid.

[0015] Preferably, a spherical bladder is fixedly connected to the end of each extension cylinder, and the bladder communicates with the inside of the extension cylinder. When no ozone gas is filled in the bladder, the volume of the bladder is small, and the diameter of the bladder is smaller than the diameters of the sleeve and trouser legs of the protective clothing. When ozone gas is introduced into the mold, the bladder expands, adheres to the inner surfaces of the sleeve and trouser legs, and slides along them, which helps to support the protective clothing open. At the same time, the bladder seals the ends of the sleeve and trouser legs, effectively confining the ozone gas inside the protective clothing, causing the protective clothing to fully expand and bulge, and reducing the wrinkled areas on the surface of the protective clothing.

[0016] The advantages of the present invention are as follows:

[0017] 1. In the present invention, the mold is in the shape of a human body, and the protective clothing is sleeved on the mold. The soft protective clothing is supported open, and the wrinkled parts on the surface of the protective clothing are also flattened. Then, it is moved under the arc-shaped plate, and the liquid sprayed by the nozzle can fully cover the surface of the protective clothing, achieving full disinfection and sterilization treatment of the protective clothing. At the same time, the efficiency is high. By sleeving on the mold, automatic cleaning treatment of the protective clothing can be realized, meeting the needs of the front line.

[0018] 2. In the present invention, the protective clothing is pre-sleeved on the mold that is not installed on the operating table, and then the mold is installed on the slider, making preparations in advance. Moreover, there is no need to wait until the mold moves to one end of the operating table to remove the protective clothing on the mold and then sleeve on the protective clothing again, which can improve the efficiency. At the same time, one person stands on each side of the two ends of the operating table, and two people at the diagonal positions of the operating table cooperate. One person installs the mold, and the other person removes the mold. At the same time, during the removal process, the person on the opposite side installs the mold, and the two cooperate with each other to improve the efficiency again.

A lead screw 3 is rotatably connected in the chute 2. A slider 4 is drivingly connected to the lead screw 3. A support rod 5 is vertically fixed to the upper end surface of the slider 4. A mold 6 in the shape of a human body is fixed to the end of the support rod 5. A protective clothing is sleeved on the mold 6; an arc plate 7 is provided in the middle area of the operating table 1. The inside of the arc plate 7 is hollow. A plurality of nozzles 8 are provided on the inner surface of the arc plate 7. A plurality of nozzles 8 are also provided in the middle area of the operating table 1; the end of the lead screw 3 is connected to the output end of a motor, and the forward and reverse rotation of the motor realizes the reciprocating movement of the slider 4 in the chute 2; the inside of the arc plate 7 is hollow. The inside of the arc plate 7 is connected to an external liquid supply pump. The liquid supply pump injects the disinfected and sterilized liquid into the arc plate 7, and then sprays it out from the nozzles 8 on the arc plate 7; the nozzles 8 on the operating table 1 are also connected to an external liquid supply pump, and the nozzles 8 spray the disinfected and sterilized liquid; the operator sleeved the used protective clothing on the mold 6, and then through the rotation of the lead screw 3, the slider 4 drives the mold 6 to move through the support rod 5, bringing the protective clothing under the arc plate 7. At the same time, driven by the liquid supply pump, the liquid impacts on the protective clothing to realize the disinfection and sterilization treatment of the protective clothing; because the mold 6 is in the shape of a human body and the protective clothing is sleeved on the mold 6, the soft protective clothing is supported and opened, and the wrinkled parts on the surface of the protective clothing are also flattened. Then it moves under the arc plate 7, and the liquid sprayed by the nozzles 8 can fully cover the surface of the protective clothing, fully disinfecting and sterilizing the protective clothing. At the same time, the efficiency is high. When sleeved on the mold 6, the automatic cleaning treatment of the protective clothing can be realized, which can meet the needs of the front line.

[0031] Referring to Figure 4, the support rod 5 includes a movable rod 9 and a fixed rod 10; the fixed rod 10 is fixedly connected to the slider 4, a jack 11 is opened at the end of the fixed rod 10, the movable rod 9 is inserted into the jack 11, and the end of the movable rod 9 is fixedly connected to the mold 6; during operation, the operator can be beside the operating table 1. First, put the protective suit on the mold 6, and then when the slider 4 moves to one end position of the operating table 1, insert the movable rod 9 into the jack 11 on the fixed rod 10. At this time, the mold 6 can be quickly installed on the slider 4; put the protective suit on the mold 6 that is not installed on the operating table 1 in advance, and then install the mold 6 on the slider 4 to make preparations in advance, and there is no need to wait until the mold 6 moves to one end of the operating table 1, remove the protective suit on the mold 6, and then put on the protective suit again, which can improve the efficiency; at the same time, one person stands on each side of the two ends of the operating table 1, and two people at the diagonal positions of the operating table 1 cooperate. One person installs the mold 6 and the other person removes the mold 6. At the same time, during the removal process, the person on the opposite side installs the mold 6, and the two cooperate with each other to improve the efficiency again.

[0032] Referring to Figure 2 and Figure 4 , the inside of the mold 6 is hollow, and the mold 6 includes a head 12, a torso 13 and limbs 14; the head 12 is fixedly connected to the movable rod 9, the head 12 is fixedly connected to the torso 13, the limbs 14 are connected to the torso 13 through springs, the limbs 14 are connected to the inside of the torso 13 through hoses, and air holes 15 are opened on the surfaces of the head 12, the torso 13 and the limbs 14; the movable rod 9 and the fixed rod 10 are axially penetrated, the movable rod 9 communicates with the inside of the head 12, the movable rod 9 communicates with the fixed rod 10, the jack 11 inside the fixed rod 10 communicates with an air duct 16 opened in the solid part inside the slider 4, and the air duct 16 is connected to an external air supply pump through a pipe; the air duct 16 is connected to an external air pump through a pipeline, and the air pump injects ozone sterilizing gas into the air duct 16. Then, the ozone sequentially passes through the inside of the jack 11 and the movable rod 9 and is injected into the mold 6. Then, the ozone is discharged from the air holes 15 on the head 12, the torso 13 and the limbs 14, impacting on the inner surface of the protective suit. First, it disinfects the inner surface of the protective suit to improve the cleanliness of the protective suit. Second, the ozone gas impacts inside the protective suit to expand the protective suit, so that the parts of the mold 6 that cannot be extended and supported inside the protective suit can also be supported and bulged, which helps the spray head 8 to spray disinfectant liquid for the treatment of the protective suit.

[0033] Referring to Figure 2 and Figure 3, the limb 14 includes a fixed cylinder 17 and an extension cylinder 18; the extension cylinder 18 is slidably connected to the inside of the fixed cylinder 18 through a tension spring. An air inlet is provided at the inner end of the extension cylinder 18, and air holes 15 are provided on the surfaces of the extension cylinder 18 and the fixed cylinder 17. When ozone gas is not injected into the mold 6, the extension cylinder 18 is placed inside the fixed cylinder 17 through the tension spring. At this time, the overall volume of the mold 6 is smaller, which is convenient for sleeving the protective clothing on the mold 6 and helps to improve the efficiency of sleeving the protective clothing on the mold 6. After injecting ozone gas, the gas impacts the inner end of the extension cylinder 18, gradually pushing the extension cylinder 18 out of the fixed cylinder 17. The ozone gas sprays out from the air holes 15, and the ozone gas supports the protective clothing open. After the protective clothing is disinfected by the liquid sprayed from the nozzle 8, the ozone gas is no longer supplied. At this time, the extension cylinder 18 resets under the tension of the tension spring. At this time, the overall volume of the mold 6 decreases, which helps to remove the protective clothing from the mold 6, facilitates the operation of the operator, and helps to improve the disinfection and sterilization efficiency.

[0034] Refer to Figure 4 , a sealing ball 19 connected by a spring is provided at the inner bottom of the jack 11. Above the sealing ball 19, there is a ring body 20. The outer circle of the ring body 20 is hermetically fixed to the inner side wall of the jack 11, and the sealing ball 19 is inside the inner circle of the ring body 20. Above the ring body 20, there is a T-shaped rod 21 connected by a spring. The lower end of the T-shaped rod 21 abuts against the sealing ball 19. When the mold 6 is not installed on the slider 4, the protective clothing is sleeved on the mold 6. At this time, the extension cylinder 18 is placed inside the fixed cylinder 17. After the protective clothing is sleeved, first insert the air nozzle of an external air pump into the movable rod 9, inject gas into the mold 6, and then the gas sprays out from the air holes 15. At the same time, the extension cylinder 18 extends outwards, supporting the protective clothing open, that is, first support the protective clothing open and unfold the wrinkled or bent parts of the protective clothing rope. After the mold 6 is installed on the slider 4 later, ozone gas is injected. At this time, the protective clothing can be smoothly unfolded. The setting of the T-shaped rod 21 and the sealing ball 19 is such that after the movable rod 9 is inserted into the jack 11, under the elastic force of the spring and the pressure of the anode ozone gas, the sealing ball 19 blocks the ozone. After the mold 6 is installed on the slider 4, that is, after the movable rod 9 is inserted into the jack 11, the lower end of the movable rod 9 presses down the T-shaped rod 21, and the T-shaped rod 21 pushes down the sealing ball 19, opening the inner circle of the ring body 20. At this time, ozone gas is injected into the movable rod 9 to fill the mold 6 with ozone gas. The setting of the sealing ball 19 is to save ozone gas to prevent ozone gas from continuously spraying out from the jack 11 and wasting ozone gas when the mold 6 is not installed on the slider 4.

[0035] Refer to Figure 1 , Figure 5 and Figure 6, a cavity 22 is provided inside the middle area of the operation table 1, and a plurality of rotating grooves 23 are provided on the surface of the middle area of the operation table 1. The rotating grooves 23 communicate with the cavity 22. The outer ring of the nozzle 8 is connected to the inner side wall of the rotating groove 23 through a conical spring. The nozzles 8 are arranged in rows. The nozzles 8 in the same row are evenly divided into a group by the sliding groove 2. The nozzles 8 in a group are all connected to an air supply pipe 24. One end of the air supply pipe 24 penetrates to the outside of the operation table 1 and is rotatably connected to the inside of the side wall of the operation table 1 through a torsion spring. The other end of the air supply pipe 24 is closed; a strip-shaped through hole 25 is provided on the inner side wall of the sliding groove 2. The other end of the air supply pipe 24 penetrates through the through hole 25 and protrudes from the inner side wall of the sliding groove 2; when the slider 4 moves in the sliding groove 2, the side wall of the slider 4 intermittently presses the other end of the air supply pipe 24, and then the air supply pipe 24 swings towards the slider 4 in the through hole 25. At the same time, the air supply pipe 24 drives the nozzle 8 to swing. The nozzle 8 pulls the conical spring and tilts, so that the disinfection and sterilization liquid sprayed out of the nozzle 8 impacts and discharges at a certain inclination angle. In the case of wrinkles on the surface of the protective clothing, the liquid can also be sprayed into the wrinkle gaps, improving the disinfection and sterilization effect on the protective clothing.

[0036] Refer to Figure 6 , the other end of the air supply pipe 24 is rotatably connected to the upper and lower rotating bodies 26; a notch 27 is provided on the outer ring of the through hole 25, and the height of the notch 27 is greater than the height of the upper and lower rotating bodies 26; the slider 4 presses the air supply pipe 24, and the air supply pipe 24 swings in the cavity 22. After the slider 4 disengages from the air supply pipe 24, the air supply pipe 24 automatically resets under the torsion of the torsion spring. Moreover, if the slider 4 repeatedly presses and wears against the air supply pipe 24, it will cause the other end of the air supply pipe 24 to wear and crack, and at the same time, it will also cause wear on the side wall of the slider 4. Therefore, the rotating body 26 is provided. Each time the slider 4 presses the air supply pipe 24, the slider 4 rubs the rotating body 26 to rotate, avoiding direct contact and wear with the other end of the air supply pipe 24. The air supply pipe 24 swings towards the through hole 25. At the same time, the rotating body 26 is pressed in the notch 27, and the outer ring of the rotating body 26 is flush with the inner side wall of the sliding groove 2. The slider 4 smoothly disengages from the rotating body 26. After that, the air supply pipe 24 automatically resets under the torsion spring, preparing for the next swing.

[0037] Refer to Figure 7, the nozzles 8 on the operating table 1 are divided into a first-zone nozzle 81, a second-zone nozzle 82 and a third-zone nozzle 83. The second-zone nozzle 82 is located between the first-zone nozzle 81 and the third-zone nozzle 83, and the gas supply pipes 24 connected to the first-zone nozzle 81 and the third-zone nozzle 83 are arranged in two branches; the second-zone nozzle 82 faces the arc-shaped plate 7, and the first-zone nozzle 81 and the third-zone nozzle 83 are located on both sides of the arc-shaped plate 7 in the vertical direction; the gas supply pipe 24 is arranged in two branches, one branch is connected to an external pump body for supplying dry hot air, and the other branch is connected to an external pump body for supplying liquid disinfection and sterilization liquid; when the mold 6 moves from the first-zone nozzle 81 towards the third-zone nozzle 83, the first-zone nozzle 81 and the second-zone nozzle 82 spray the disinfection and sterilization liquid. When the mold 6 moves to the position of the third-zone nozzle 83, the gas supply pipe 24 connected to the third-zone nozzle 83 injects dry hot air flow inside to dry the protective clothing; when the mold 6 moves from the third-zone nozzle 83 towards the first-zone nozzle 81, the third-zone nozzle 83 and the second-zone nozzle 82 spray the disinfection and sterilization liquid. When the mold 6 moves to the position of the first-zone nozzle 81, the gas supply pipe 24 connected to the first-zone nozzle 81 injects dry hot air flow inside to dry the protective clothing; drying the wet protective clothing in advance helps to dry and sort the protective clothing when it is taken off later.

[0038] Refer to Figure 4 , a positioning rod 29 is fixedly connected to one side of the lower end of the movable rod 9. The positioning rod 29 is inserted into a positioning hole 30 opened on one side of the upper end surface of the fixed rod 10; by setting the positioning rod 29, after the fixed rod 10 is inserted into the insertion hole 11, the positioning rod 29 is inserted into the positioning hole 30 to restrict the rotational constraint between the fixed rod 10 and the movable rod 9, ensuring that the mold 6 can stably move along the sliding groove 2 to the lower part of the arc-shaped plate 7, preventing the mold 6 from rotating in the horizontal direction, and preventing the edge position of the mold 6 from touching the nozzle 8 and hindering the ejection of the liquid.

[0039] Embodiment 2:

[0040] Refer to Figure 8 , compared with Embodiment 1, as another implementation manner of the present invention, a spherical bladder 31 is fixedly connected to the end of each extension cylinder 18, and the bladder 31 communicates with the inside of the extension cylinder 18; with the provided bladder 31, when no ozone gas is filled in the bladder 31, the volume of the bladder 31 is small, and the diameter of the bladder 31 is smaller than the diameters of the sleeves and trouser legs of the protective clothing. When ozone gas is introduced into the mold 6, the bladder 31 expands, adheres to the inner surfaces of the sleeves and trouser legs and slides along them, which helps to support the protective clothing open. At the same time, the bladder 31 blocks the ends of the sleeves and trouser legs, effectively confining the ozone gas inside the protective clothing, causing the protective clothing to fully expand and bulge, and reducing the wrinkled area on the surface of the protective clothing.

[0041] Working principle: The end of the lead screw 3 is connected to the output end of the motor, and the forward and reverse rotation of the motor enables the slider 4 to move back and forth in the chute 2; the inside of the arc-shaped plate 7 is hollow, and the inside of the arc-shaped plate 7 is connected to an external liquid supply pump. The liquid supply pump injects the disinfected and sterilized liquid into the arc-shaped plate 7, and then sprays it out from the nozzle 8 on the arc-shaped plate 7; the nozzle 8 on the operating table 1 is also connected to an external liquid supply pump, and the nozzle 8 sprays the disinfected and sterilized liquid; the operator puts the used protective clothing on the mold 6, and then through the rotation of the lead screw 3, the slider 4 drives the mold 6 to move through the support rod 5, bringing the protective clothing under the arc-shaped plate 7. At the same time, driven by the liquid supply pump, the liquid impacts on the protective clothing to achieve the disinfection and sterilization treatment of the protective clothing; since the mold 6 is in the shape of a human body and the protective clothing is sleeved on the mold 6, the soft protective clothing is supported and opened, and the wrinkled parts on the surface of the protective clothing are also flattened. Then it moves under the arc-shaped plate 7, and the liquid sprayed by the nozzle 8 can fully cover the surface of the protective clothing, fully disinfecting and sterilizing the protective clothing. At the same time, the efficiency is high. By sleeving on the mold 6, the automatic cleaning treatment of the protective clothing can be realized, which can meet the needs of the front line;

[0042] During operation, the operator can be beside the operating table 1. First, put the protective clothing on the mold 6, and then when the slider 4 moves to one end position of the operating table 1, insert the movable rod 9 into the jack 11 on the fixed rod 10, and at this time, the mold 6 can be quickly installed on the slider 4; put the protective clothing on the mold 6 in advance that is not installed on the operating table 1, and then install the mold 6 on the slider 4 to make preparations in advance, and there is no need to wait until the mold 6 moves to one end of the operating table 1, then take off the protective clothing on the mold 6 and then put on the protective clothing again, which can improve the efficiency; at the same time, one person stands on each side of the two ends of the operating table 1, and two people at the diagonal positions of the operating table 1 cooperate. One person installs the mold 6, and the other person takes off the mold 6. At the same time, during the removal process, the person on the opposite side installs the mold 6, and the two cooperate with each other to improve the efficiency again;

[0043] The air duct 16 is connected to an external air pump through a pipeline. The air pump injects ozone sterilization gas into the air duct 16, and then the ozone sequentially passes through the inside of the movable rod 9 along the jack 11 and is injected into the mold 6. Then the ozone is discharged from the air holes 15 on the head 12, the torso 13 and the limbs 14, impacting on the inner surface of the protective clothing. First, it disinfects the inner surface of the protective clothing to improve the cleanliness of the protective clothing. Second, the ozone gas impacts inside the protective clothing to expand the protective clothing, so that the parts that the mold 6 fails to extend and support inside the protective clothing can also be supported and bulged, which helps the nozzle 8 spray the disinfected liquid to treat the protective clothing;

[0044] When ozone gas is not injected into the interior of the mold 6, the extension cylinder 18 is placed inside the fixed cylinder 17 by a tension spring. At this time, the overall volume of the mold 6 is relatively small, which facilitates sleeving the protective clothing on the mold 6, helping to improve the efficiency of sleeving the protective clothing on the mold 6. After ozone gas is injected, the gas impacts the inner end of the extension cylinder 18, gradually pushing the extension cylinder 18 out of the fixed cylinder 17. The ozone gas sprays out from the air holes 15, and the ozone gas supports the protective clothing open. After the protective clothing is disinfected by the liquid sprayed from the spray head 8, the ozone gas supply is stopped. At this time, the extension cylinder 18 resets under the pulling force of the tension spring, and the overall volume of the mold 6 decreases, which helps to remove the protective clothing from the mold 6, facilitating the operation of the operator and helping to improve the disinfection and sterilization efficiency;

[0045] When the mold 6 is not installed on the slider 4, the protective clothing is sleeved on the mold 6. At this time, the extension cylinder 18 is placed inside the fixed cylinder 17. After the protective clothing is properly sleeved, first, the nozzle of an external air pump is inserted into the movable rod 9, and gas is injected into the mold 6. Then the gas sprays out from the air holes 15, and at the same time, the extension cylinder 18 extends outwards, supporting the protective clothing open. That is, the protective clothing is first supported open, and the wrinkled or bent parts of the protective clothing rope are unfolded. After the mold 6 is installed on the slider 4 later, ozone gas is injected, and the protective clothing can be smoothly unfolded at this time; The setting of the T-shaped rod 21 and the sealing ball 19 is such that after the movable rod 9 is inserted into the jack 11, under the elastic force of the spring and the pressure of the anode ozone gas, the sealing ball 19 blocks the ozone. After the mold 6 is installed on the slider 4, that is, after the movable rod 9 is inserted into the jack 11, the lower end of the movable rod 9 presses down on the T-shaped rod 21, and the T-shaped rod 21 pushes down the sealing ball 19, opening the inner ring of the ring body 20. At this time, ozone gas is injected into the movable rod 9, filling the mold 6 with ozone gas; The setting of the sealing ball 19 is to save ozone gas to prevent ozone gas from continuously spraying out from the jack 11 when the mold 6 is not installed on the slider 4, resulting in waste of ozone gas;

[0046] When the slider 4 moves in the chute 2, the side wall of the slider 4 intermittently presses the other end of the air supply pipe 24. Then the air supply pipe 24 swings towards the slider 4 in the through hole 25. At the same time, the air supply pipe 24 drives the spray head 8 to swing, and the spray head 8 pulls the conical spring and tilts, causing the disinfection and sterilization liquid sprayed from the spray head 8 to impact and discharge at a certain inclination angle. In the case where there are wrinkles on the surface of the protective clothing, the liquid can also be sprayed into the wrinkle gaps, improving the disinfection and sterilization effect on the protective clothing;

[0047] The slider 4 presses against the air supply pipe 24, causing the air supply pipe 24 to swing within the cavity 22. After the slider 4 disengages from the air supply pipe 24, the air supply pipe 24 automatically resets under the torsion force of the torsion spring. Moreover, if the slider 4 repeatedly presses against and wears the air supply pipe 24, it will cause the other end of the air supply pipe 24 to wear and crack, and at the same time, it will also cause wear on the side wall of the slider 4. Therefore, a wheel body 26 is provided. Each time the slider 4 presses against the air supply pipe 24, the slider 4 rubs the wheel body 26 to rotate, avoiding direct contact and wear with the other end of the air supply pipe 24. The air supply pipe 24 swings towards the through hole 25 side, and at the same time, the wheel body 26 is pressed within the notch 27. The outer ring of the wheel body 26 is flush with the inner side wall of the chute 2, and the slider 4 smoothly disengages from the wheel body 26. After that, the air supply pipe 24 automatically resets under the torsion spring, preparing for the next swing;

[0048] The second - area nozzle 82 faces the arc - shaped plate 7. The first - area nozzle 81 and the third - area nozzle 83 are located on both sides of the arc - shaped plate 7 in the vertical direction. The air supply pipe 24 is arranged in two paths. One path is connected to a pump body that supplies dry hot air from the outside, and the other path is connected to a pump body that supplies liquid for disinfection and sterilization from the outside. When the mold 6 moves from the first - area nozzle 81 towards the third - area nozzle 83, the first - area nozzle 81 and the second - area nozzle 82 spray the disinfection and sterilization liquid. When the mold 6 moves to the position of the third - area nozzle 83, the air supply pipe 24 connected to the third - area nozzle 83 injects dry hot air flow inside to dry the protective clothing. When the mold 6 moves from the third - area nozzle 83 towards the first - area nozzle 81, the third - area nozzle 83 and the second - area nozzle 82 spray the disinfection and sterilization liquid. When the mold 6 moves to the position of the first - area nozzle 81, the air supply pipe 24 connected to the first - area nozzle 81 injects dry hot air flow inside to dry the protective clothing. Drying the wet protective clothing in advance is helpful for the drying and finishing of the protective clothing when it is taken off later;

[0049] By setting the positioning rod 29, after the fixed rod 10 is inserted into the jack 11, the positioning rod 29 is inserted into the positioning hole 30, restricting the rotational constraint between the fixed rod 10 and the movable rod 9, ensuring that the mold 6 can stably move along the chute 2 to the lower part of the arc - shaped plate 7, preventing the mold 6 from rotating in the horizontal direction, and preventing the edge position of the mold 6 from touching the nozzle 8 and hindering the spraying of the liquid.
