Description

Technical Field

[0001] This invention belongs to the field of disinfection cabinets, specifically an exhaust device for a medical disinfection cabinet. Background Technology

[0002] Hospital nurses typically need to use sterilization cabinets during their work to disinfect medical equipment used by doctors and items such as bed sheets in the hospital. Sterilization cabinets can disinfect through methods such as high temperature, ultraviolet light, infrared light, and ozone. Existing high-temperature sterilization cabinets disinfect items by heating them, and at the same time, exhaust devices are needed to expel the steam generated by heating the items from the sterilization cabinet to ensure that the sterilization cabinet and items are dry after sterilization.

[0003] A patent application with publication number CN115381991B discloses a front-exhaust disinfection cabinet, including a cabinet body and a drawer on the cabinet body. The drawer has a handle on the outer wall and a fan on the inner wall. The handle has a first inner cavity with an exhaust pipe. The air inlet of the exhaust pipe is connected to the air outlet of the fan, and the air outlet faces the outside. The exhaust pipe can directly exhaust the water vapor in the cabinet body from the front of the handle.

[0004] The gas emitted by the disinfection cabinet in the above scheme can easily make the environment around the disinfection cabinet humid. At the same time, after the steam is discharged from the disinfection cabinet, the air pressure inside the disinfection cabinet drops. At this time, it is necessary to introduce the surrounding air into the disinfection cabinet. The outside air entering the disinfection cabinet needs to be reheated, which affects the working efficiency of the disinfection cabinet.

[0005] Therefore, the present invention provides an exhaust device for a medical disinfection cabinet. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: An exhaust device for a medical disinfection cabinet, comprising an exhaust pipe installed on the disinfection cabinet, and further comprising: an exhaust port opened on the exhaust pipe; an air inlet opened on the exhaust pipe; a blower installed on the exhaust pipe, the blower being used to blow gas from inside the disinfection cabinet into the air inlet and out through the exhaust port; a heater installed on the exhaust pipe, the heater being used to heat the air inside the exhaust pipe; and a drying assembly installed at one end of the air inlet, the drying assembly comprising: a first annular block installed on the side wall of the disinfection cabinet, the first annular block being in close contact with the end of the exhaust pipe near the exhaust port; and a first drying bag detachably installed inside the first annular block, the first drying bag being used to dry the air inside the disinfection cabinet.

[0008] Preferably, two drying components are installed on the side wall of the disinfection cabinet, and the drying components are slidably connected to the disinfection cabinet vertically.

[0009] Preferably, it further includes: a concave plate fixedly installed on the side wall of the disinfection cabinet; the drying assembly further includes: two square plates slidably installed in the concave plate; a threaded rod rotatably installed in the concave plate, the threaded rod being threadedly connected to the square plate; and round rods installed on the square plate, the two round rods being located on the upper and lower sides of the first annular block.

[0010] Preferably, it also includes an insulation shell installed on the side wall of the disinfection cabinet, with the exhaust pipe and the drying component located between the insulation shell and the disinfection cabinet.

[0011] Preferably, the drying assembly further includes: a second annular block rotatably mounted on the first annular block; and a second drying package mounted inside the second annular block.

[0012] Preferably, the drying assembly further includes: a torsion spring installed between the first and second annular blocks; a connecting plate installed on one of the round rods near the torsion spring, the round rod near the torsion spring being rotatably connected to the square plate; a push rod installed on the connecting plate; a gear fixedly installed on the round rod near the torsion spring; a rack plate driving the gear to rotate, the rack plate being fixedly installed on the side wall of the disinfection cabinet; and a third spring installed between the rack plate and the disinfection cabinet.

[0013] Preferably, it also includes a cleaning component installed on the side wall of the disinfection cabinet. The cleaning component is used to clean the surface of the first drying pack near the disinfection cabinet. The cleaning component includes: a sliding plate slidably installed on the disinfection cabinet; two support rods installed on the disinfection cabinet; a rotating rod rotatably installed on the support rods, with tape wound on the rotating rod and the tape covering the surface of the sliding plate; and a pressure block fixedly installed on the sliding plate, with the tape passing between the pressure block and the sliding plate.

[0014] Preferably, the cleaning assembly further includes: a push plate for moving the sliding plate, the push plate being slidably connected to the disinfection cabinet; a pusher for moving the push plate, the pusher being slidably connected to the disinfection cabinet; and a plurality of springs installed between the push plate and the disinfection cabinet.

[0015] Preferably, the cleaning component further includes: a first cover plate slidably mounted on the insulation shell; a groove formed on the push plate; a plurality of first triangular blocks slidably mounted in the groove; a second spring mounted between the first triangular blocks and the groove; and a plurality of second triangular blocks fixedly mounted between the pushers.

[0016] Preferably, it also includes two secondary covers that slide inside the disinfection cabinet, the secondary covers being used to seal the drying component and the exhaust pipe.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The exhaust device of the medical disinfection cabinet described in this invention addresses the issue that the exhaust gas from existing disinfection cabinets easily makes the surrounding environment humid. Furthermore, after the steam is expelled from the disinfection cabinet, the air pressure inside the cabinet drops, requiring the introduction of ambient air into the cabinet. This external air needs to be reheated, affecting the cabinet's efficiency. By setting up a primary drying pack to dry the circulating air in the disinfection cabinet, the problem is solved, eliminating the need for air exchange with the outside air. This improves the efficiency of the disinfection cabinet by saving time spent heating the external air while maintaining dryness.

[0019] 2. The exhaust device of the medical disinfection cabinet of the present invention, by setting two drying components, when the first drying pack in one of the drying components is saturated with water, the two drying components can be controlled to slide up and down to replace each other. With the help of the heat insulation shell, the temperature inside the exhaust pipe can be kept warm, which improves the problem of temperature loss. In addition, by setting the heat insulation shell to keep the part of the exhaust pipe located outside the disinfection cabinet warm, the temperature between the heat insulation shell and the side wall of the disinfection cabinet is relatively high. At this time, the first drying pack that is saturated with water can be heated to dehydrate the silica gel desiccant in the first drying pack under high temperature conditions, so that the silica gel desiccant in the first drying pack can be reused.

[0020] 3. The exhaust device of the medical disinfection cabinet of the present invention, by setting a second ring block that can rotate relative to the first ring block, can rotate the second ring block when dehydrating the silica gel desiccant in the drying component, thereby driving the second drying pack to rotate and separating the first drying pack and the second drying pack. Compared with the whole dehydration effect, the dehydration effect of dividing the silica gel desiccant into two parts is better. With the help of gears and rack plates, the push rod can automatically rotate when the two drying components are replaced, so as to realize the automatic rotation of the second ring block. The structure is simple and easy to use.

[0021] 4. The exhaust device of the medical disinfection cabinet described in this invention addresses the issue that, due to factors such as dust particles in the air and debris attached to the disinfected items, dust and debris easily adhere to the surface of the first drying pack near the disinfection cabinet after prolonged use. If left untreated, this can easily affect the ventilation rate of the drying component. By using adhesive tape to adhere the dust and debris to the surface of the first drying pack, the problem is improved, ensuring the normal operation of the drying component.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1

[0036] like Figure 1-10 As shown in the embodiment of the present invention, an exhaust device for a medical disinfection cabinet includes an exhaust pipe 2 installed on the disinfection cabinet 100, and further includes: an exhaust port 3 opened on the exhaust pipe 2; an air inlet 11 opened on the exhaust pipe 2; a blower 4 installed on the exhaust pipe 2, the blower 4 being used to blow gas inside the disinfection cabinet 100 into the air inlet 11 and out through the exhaust port 3; a heater 5 installed on the exhaust pipe 2, the heater 5 being used to heat the air inside the exhaust pipe 2; and a drying component 6 installed at one end of the air inlet 11, the drying component 6 including: a first ring block 61 installed on the side wall of the disinfection cabinet 100, the first ring block 61 being in close contact with the end of the exhaust pipe 2 near the exhaust port 3; and a first drying bag 62 detachably installed inside the first ring block 61, the first drying bag 62 being used to dry the air inside the disinfection cabinet 100.

[0037] Specifically, the first drying pack 62 contains silica gel desiccant, the blower 4 is a duct blower 4, and the heater 5 is an air-type electric heater 5. Before operation, the items to be disinfected are placed in the disinfection cabinet 100, and then the blower 4 and heater 5 are turned on, allowing air inside the disinfection cabinet 100 to enter through the air inlet 11 of the exhaust pipe 2. Before entering the exhaust pipe 2, the air passes through the first drying pack 62, which dries the incoming air. The dried air is then heated into hot air by the heater 5 and discharged from the exhaust port 3. The discharged air disinfects the items inside the disinfection cabinet 100. The air discharged from the existing disinfection cabinet 100... The environment around the disinfection cabinet 100 is easily humidified. Simultaneously, after the steam is expelled from the disinfection cabinet 100, the air pressure inside the cabinet drops. This necessitates introducing ambient air into the disinfection cabinet 100, requiring reheating of the incoming air, thus affecting its efficiency. By installing a first drying pack 62 to dry the circulating air within the disinfection cabinet 100, the problem is solved, eliminating the need for air exchange. This saves time on heating the external air while maintaining dryness, thereby improving the disinfection cabinet 100's efficiency.

[0038] like Figure 4 As shown, two drying components 6 are installed on the side wall of the disinfection cabinet 100, and the drying components 6 are slidably connected to the disinfection cabinet 100.

[0039] Specifically, in existing technologies, once the desiccant becomes saturated with water, the entire device needs to be disassembled for replacement, which is quite cumbersome. By setting up two drying components 6, when the first drying pack 62 in one of the drying components 6 becomes saturated with water, the two drying components 6 can be controlled to slide up and down for replacement, ensuring that the device can work normally. Subsequently, the saturated first drying pack 62 can be disassembled and a new first drying pack 62 can be installed without disassembling the entire device, thus improving the aforementioned problems.

[0040] like Figure 4-6 As shown, it also includes: a concave plate 7 fixedly installed on the side wall of the disinfection cabinet 100; the drying component 6 also includes: two square plates 63 slidably installed in the concave plate 7; a threaded rod 64 rotatably installed in the concave plate 7, the threaded rod 64 being threadedly connected to the square plate 63; and round rods 65 installed on the square plate 63, the two round rods 65 being located on the upper and lower sides of the first ring block 61.

[0041] Specifically, the square plate 63 can slide up and down relative to the concave plate 7, the threaded rod 64 is electrically controlled, and the initial positions of the two drying components 6 are as follows: Figure 4 As shown; when the first drying pack 62 in the drying component 6 connected to the disinfection cabinet 100 is saturated with water, the threaded rod 64 is rotated, which drives the square plate 63 on the threaded rod 64 to move upward, which in turn drives the round rod 65 to move upward. The movement of the round rod 65 pushes the first ring block 61 to move upward until the first ring block 61 located at the bottom moves to the air inlet 11 of the exhaust pipe 2, thus realizing the alternation of the two drying components 6; by setting the round rod 65 to move the first ring block 61, the alternation of the two drying components 6 can be realized, which is convenient to use.

[0042] like Figure 4-6 As shown, the heat preservation shell 8 is installed on the side wall of the disinfection cabinet 100, and the exhaust pipe 2 and the drying component 6 are both located between the heat preservation shell 8 and the disinfection cabinet 100.

[0043] Specifically, since the temperature required for disinfecting items inside the disinfection cabinet 100 is relatively high, the temperature inside the exhaust pipe 2 is also high, which can affect the temperature of the surrounding environment. By setting up the insulation shell 8, the temperature inside the exhaust pipe 2 can be kept warm, thus improving the problem of temperature loss. Furthermore, by setting up the insulation shell 8 to keep warm the part of the exhaust pipe 2 located outside the disinfection cabinet 100, the temperature between the insulation shell 8 and the side wall of the disinfection cabinet 100 is relatively high. At this time, the first drying pack 62, which is saturated with water, can be heated to dehydrate the silica gel desiccant inside the first drying pack 62 under high temperature conditions, so that the silica gel desiccant inside the first drying pack 62 can be reused.

[0044] like Figure 5As shown, the drying assembly 6 further includes: a second annular block 66 rotatably mounted on the first annular block 61; and a second drying package 67 installed inside the second annular block 66.

[0045] Specifically, the second drying pack 67 contains silica gel desiccant. By configuring a second annular block 66 that can rotate relative to the first annular block 61, when dehydrating the silica gel desiccant in the drying assembly 6, the second annular block 66 can be rotated, causing the second drying pack 67 to rotate, thus separating the first drying pack 62 and the second drying pack 67. Figure 6 As shown, separating the silica gel desiccant into two parts results in better dehydration than dehydrating the entire product at once.

[0046] like Figure 4-7 As shown, the drying assembly 6 further includes: a torsion spring 68 installed between the first annular block 61 and the second annular block 66; a connecting plate 69 installed on one of the round rods 65 near the torsion spring 68, the round rod 65 near the torsion spring 68 being rotatably connected to the square plate 63; a push rod 610 installed on the connecting plate 69; a gear 611 fixedly installed on the round rod 65 near the torsion spring 68; a rack plate 612 driving the gear 611 to rotate, the rack plate 612 being fixedly installed on the side wall of the disinfection cabinet 100; and a third spring 613 installed between the rack plate 612 and the disinfection cabinet 100.

[0047] Specifically, spring 613 is used to push the rack plate 612 to move, so that when gear 611 moves to one side of rack plate 612, rack plate 612 is always engaged with gear 611. When ring block 61 and ring block 66 are in contact, torsion spring 68 is in a torsional state. Initially, as shown... Figure 4As shown; when the disinfection cabinet 100 finishes its operation, the control threaded rod 64 rotates, causing the square plate 63, gear 611, and round rod 65 to move upwards. The round rod 65 moves, pushing the first ring block 61 and the second ring block 66 to move. When the first ring block 61 and the second ring block 66 of the drying component 6 located below move upwards, the gear 611 contacts the rack plate 612. Because the gear 611 meshes with the rack plate 612, the gear 611 rotates when it moves upwards, causing the connecting plate 69 and the push rod 610 to rotate around the round rod 65. The rotation of the push rod 610 pushes the second ring block 66 to rotate until the second ring block 66 and the first ring block 61 are in contact. After that, the gear 611 cannot rotate, so the rack plate 612 is continuously pushed by the gear 611 towards the disinfection cabinet 100. When the drying assembly 6 moves horizontally, the first ring block 61 and the second ring block 66 located above move. During this movement, the gear 611 contacts the rack plate 612. Because the gear 611 meshes with the rack plate 612, the gear 611 rotates when moving upwards, causing the connecting plate 69 and the push rod 610 to rotate around the circular rod 65. The rotation of the push rod 610 no longer exerts a force on the second ring block 66. The second ring block 66 rotates under the elastic force of the torsion spring 68, causing the second ring block 66 to separate from the first ring block 61, so as to facilitate the heating treatment of the silica gel desiccant in the drying assembly 6. By setting the gear 611 and the rack plate 612, the push rod 610 can rotate automatically during movement, thereby realizing the automatic rotation of the second ring block 66. The structure is simple and easy to use.

[0048] like Figure 8 As shown, it also includes a cleaning component 9 installed on the side wall of the disinfection cabinet 100. The cleaning component 9 is used to clean the surface of the first drying pack 62 near the side of the disinfection cabinet 100. The cleaning component 9 includes: a sliding plate 91 slidably installed on the disinfection cabinet 100; two support rods 92 installed on the disinfection cabinet 100; a rotating rod 93 rotatably installed on the support rods 92, with tape 94 wound on the rotating rod 93 and covering the surface of the sliding plate 91; and a pressure block 95 fixedly installed on the sliding plate 91, with the tape 94 passing between the pressure block 95 and the sliding plate 91.

[0049] Specifically, the rotating rod 93 is electrically controlled to rotate. The unused end of the tape 94 is wound around the rotating rod 93 closer to the insulation shell 8, while the used end is wound around the rotating rod 93 further away from the insulation shell 8. The non-adhesive side of the tape 94 contacts the sliding plate 91. The pressure block 95 is made of glass, and the side of the pressure block 95 that contacts the tape 94 has a frosted surface to prevent the tape 94 from sticking to the pressure block 95 and causing the tape 94 to break due to excessive surface tension when the rotating rod 93 rotates. Due to dust particles in the air and debris attached to the items being disinfected, dust and debris easily adhere to the surface of the first drying bag 62 near the disinfection cabinet 100 after prolonged use. If not treated, this can easily affect the drying process. The ventilation rate of component 6; before the disinfection cabinet 100 starts working, the slide plate 91 is slid horizontally towards the first drying pack 62, while the rotating rod 93 closer to the insulation shell 8 is rotated, causing the unwound portion of the tape 94 to grow. The slide plate 91 moves to one side of the first drying pack 62, and the tape 94 on the surface of the slide plate 91 contacts the surface of the first drying pack 62, adhering dust and debris from the surface of the first drying pack 62 to the tape 94. Then, the slide plate 91 is moved away from the first drying pack 62, and at this time, the two rotating rods 93 are rotated. The rotating rod 93 away from the first drying pack 62 winds up the used tape 94. By setting the tape 94 to clean the surface of the first drying pack 62, the above-mentioned problems are improved.

[0050] like Figure 8-10 As shown, the cleaning component 9 further includes: a push plate 96 for moving the sliding plate 91, the push plate 96 being slidably connected to the disinfection cabinet 100; a pusher 97 for moving the push plate 96, the pusher 97 being slidably connected to the disinfection cabinet 100; and a plurality of first springs 98 installed between the push plate 96 and the disinfection cabinet 100.

[0051] Specifically, after all items to be disinfected are placed in the disinfection cabinet 100, the door of the disinfection cabinet 100 is closed. When the door of the disinfection cabinet 100 is closed, the pusher 97 can be pushed horizontally towards the first drying pack 62. The movement of the pusher 97 causes the push plate 96 to move synchronously, which in turn causes the slide plate 91 to move. After the slide plate 91 moves, the surface of the first drying pack 62 can be cleaned. At this time, the first spring 98 is in a stretched state. When the disinfection cabinet 100 finishes working, the door of the disinfection cabinet 100 is opened. Under the action of the elastic force of the first spring 98, the push plate 96 moves away from the first drying pack 62, causing the slide plate 91 and the pusher 97 to move synchronously back to the initial state. By pushing the pusher 97, the slide plate 91 can be moved by closing and opening the door of the disinfection cabinet 100. The structure is simple and easy to use.

[0052] like Figure 8-10As shown, the cleaning component 9 further includes: a first cover plate 99 slidably mounted on the heat preservation shell 8; a groove 910 formed on the push plate 96; a plurality of first triangular blocks 911 slidably mounted in the groove 910; a second spring 912 mounted between the first triangular block 911 and the groove 910; and a plurality of second triangular blocks 913 fixedly mounted between the push handles 97.

[0053] Specifically, the first cover plate 99 is electrically controlled to move away from the disinfection cabinet 100 before the disinfection cabinet 100 is started. When the pusher 97 pushes the push plate 96 towards the first drying bag 62, the first spring 98 extends. When the slide plate 91 moves to one side of the first ring block 61, the first spring 98 can no longer extend, and the push plate 96 cannot move. Since the pusher 97 continues to move, the second triangular block 913 on the pusher 97 can push the first triangular block 911 into the groove 910. When the second triangular block 913 of the pusher 97 is in contact with the first ring block 61, the first triangular block 911 moves into the groove 910. After the first triangular block 911 is no longer in contact, the push plate 96 returns to its initial state under the elastic force of the first spring 98. At this time, the slide plate 91 moves out of the insulation shell 8. Then, the first cover plate 99 is controlled to move towards the disinfection cabinet 100 until the first cover plate 99 isolates the disinfection cabinet 100 from the cleaning component 9. By setting the second triangular block 913 to the first triangular block 911, after the pusher 97 pushes the slide plate 91 to contact the first drying package 62, the slide plate 91 returns to its initial state, avoiding the problem that the tape 94 will fail at high temperature if it is always inside the insulation shell 8.

[0054] Example 2

[0055] like Figure 3 As shown in the first embodiment, another embodiment of the present invention includes two second cover plates 10 that are slidably installed inside the disinfection cabinet 100. The second cover plates 10 are used to seal the drying component 6 and the exhaust pipe 2.

[0056] Specifically, the second cover 10 is electrically controlled to move back and forth relative to the disinfection cabinet 100. After the disinfection cabinet 100 finishes working, the second cover 10 is controlled to seal the drying component 6 and the exhaust pipe 2, which avoids the problem of the silica gel desiccant in the drying component 6 absorbing moisture from the air when the door of the disinfection cabinet 100 is in the open state after use, and ensures that the drying component 6 can work normally when the disinfection cabinet 100 is used again.

[0057] Work steps:

[0058] Step 1: Place the items to be disinfected into the disinfection cabinet 100. Control the first cover plate 99 to move away from the disinfection cabinet 100, and close the door of the disinfection cabinet 100. When the door of the disinfection cabinet 100 is closed, push the handle 97 to move horizontally towards the first desiccant pack 62. The movement of the handle 97 causes the push plate 96 to move synchronously. The movement of the push plate 96 causes the slide plate 91 to move, and the first spring 98 to extend. At the same time, control the rotating rod 93, which is closer to the insulation shell 8, to rotate, causing the unwound portion of the tape 94 to extend. When the slide plate 91 moves to one side of the first ring block 61, the tape 94 on the surface of the slide plate 91 comes into contact with the surface of the first desiccant pack 62, and the dust and debris on the surface of the first desiccant pack 62 adhere to the tape 94. Spring 98 can no longer extend, and push plate 96 cannot move. Since push handle 97 is still moving, triangular block 913 on push handle 97 can push triangular block 911 to move into groove 910. When triangular block 913 on push handle 97 is no longer in contact with triangular block 911, push plate 96 moves away from desiccant 62 under the action of spring 98. At this time, control the two rotating rods 93 to rotate. The rotating rods 93 away from desiccant 62 will wind up the used tape 94. Then control the cover plate 99 to move closer to disinfection cabinet 100 until the cover plate 99 separates disinfection cabinet 100 from cleaning component 9, thus completing the cleaning action of desiccant 62.

[0059] Step 2: After the door of the disinfection cabinet 100 is closed, slide the second cover plate 10 until the air inlet 11 and the exhaust outlet 3 of the exhaust pipe 2 are connected to the disinfection cabinet 100. Turn on the blower 4 and the heater 5 so that the air in the disinfection cabinet 100 enters through the air inlet 11 of the exhaust pipe 2. Before entering the exhaust pipe 2, the air passes through the first drying pack 62. The first drying pack 62 dries the air blown in. The dried air is heated into hot air by the heater 5 and discharged from the exhaust outlet 3. The discharged air disinfects the items in the disinfection cabinet 100.

[0060] Step 3: After the disinfection cabinet 100 finishes working, pull the pusher 97 until the second triangular block 913 passes through the first triangular block 911, so that the pusher 97 returns to its initial state. Control the second cover plate 10 to slide and seal the drying component 6 and the exhaust pipe 2, so as to avoid the problem of the silica gel desiccant in the drying component 6 absorbing moisture from the air when the door of the disinfection cabinet 100 is in the open state after use.

[0061] Step 4: Then control the threaded rod 64 to rotate, which will drive the square plate 63, gear 611 and round rod 65 to move upward. The movement of the round rod 65 will push the first ring block 61 and the second ring block 66 to move until the first ring block 61 located at the bottom moves to the air inlet 11 of the exhaust pipe 2, thus realizing the alternation of the two drying components 6.

[0062] Step 5: Since the temperature required for disinfecting the items inside the disinfection cabinet 100 is relatively high, the temperature between the exhaust pipe 2 and the insulation shell 8 is also relatively high. When the disinfection cabinet 100 is used again, the first drying pack 62 of the used drying component 6 is heated between the exhaust pipe 2 and the insulation shell 8 so that the silica gel desiccant in the first drying pack 62 is dehydrated under high temperature conditions, so that the silica gel desiccant in the first drying pack 62 can be reused.

[0063] Step Six: As the two drying components 6 alternate, when the first annular block 61 and the second annular block 66 of the lower drying component 6 move upward, the gear 611 contacts the rack plate 612. Because the gear 611 meshes with the rack plate 612, the gear 611 rotates as it moves upward, causing the connecting plate 69 and the push rod 610 to rotate around the circular rod 65. The rotation of the push rod 610 pushes the second annular block 66 to rotate until the second annular block 66 and the first annular block 61 are in contact. After that, the gear 611 can no longer rotate, so the rack plate 612 is continuously pushed closer to the disinfection cabinet by the force of the gear 611. When the drying assembly 6 moves horizontally in the direction of 100, the first ring block 61 and the second ring block 66 located above move. The gear 611 contacts the rack plate 612. Since the gear 611 meshes with the rack plate 612, the gear 611 rotates when it moves upward, driving the connecting plate 69 and the push rod 610 to rotate around the circular rod 65 as the axis. The rotation of the push rod 610 no longer exerts a force on the second ring block 66. The second ring block 66 rotates under the action of the torsion spring 68, causing the second ring block 66 and the first ring block 61 to separate, so as to heat the silica gel desiccant in the drying assembly 6.
