The bottom of the scraper 305 is in contact with the inner bottom of the guide surface 303, and the cross section of the scraper 305 is arc-shaped. The outer surface of the first rotating shaft 304 is fixedly connected to a first pulley 306, and the first pulley 306 is located on the upper side of the scraper 305. The top of the guide surface 303 is rotatably connected to a second rotating shaft 307, and the outer surface of the second rotating shaft 307 is fixedly connected to a second pulley 308.

The upper end surface of the second rotating shaft 307 is fixedly connected to a ratchet gear 310, and the ratchet gear 310 matches the position of the toothed plate 508.

[0023] The use steps of the present invention are as follows: when the pulsating vacuum sterilizer is used, the side frame 604 is pulled out from the closed box 301, and the articles to be sterilized are placed above the multiple baffles 608, and the multiple baffles 608 cooperate to provide support for the bottom of the articles. After the articles are placed, the side frame 604 is returned to the closed box 301, the cabinet door 2 is closed, and the pulsating vacuum sterilizer is started to start the sterilization process. When the air pressure in the closed box 301 decreases, the piston 411 will be displaced toward the side plate 403. The setting of the baffle 404 plays a role in blocking and limiting the displacement of the piston 411. After the vacuum is completed in the closed box 301, the high pressure state is switched inside the closed box 301. At this time, steam is input into the closed box 301, so that the inside of the closed box 301 is in a high pressure state. In the state of high temperature and high pressure, when the air pressure inside the closed box 301 rises, the piston 411 will be pushed outward, and when the piston 411 moves, it will drive the connecting plate 409 to move along through the connection of the connecting rod 410. When the connecting plate 409 moves, the piston 411 can drive the side frame 502 to move along through the connection of the fixing rod 501, and the side frame 502 will drive the wave plate 504 to move along. After the wave plate 504 moves, the supporting state of the round block 609 will change. The round block 609 originally at a high position will correspond to the concave position of the wave plate 504, and the round block 609 originally at a low position will correspond to the arc-shaped wave block position of the wave plate 504. At this time, the supporting state of the object can be changed, and the blocking rod 60 that originally provided support will be 8 moves down, and the other blocking rods 608 move up to provide support for the articles. At this time, the displacement of the blocking rods 608 will cause the placement of the articles to shake, thereby causing the original bottom contact position of the articles to change, and the blocked position will be exposed for sterilization. Under the multiple changes in air pressure inside the closed box 301, the position of the articles can be moved multiple times to ensure that the bottom support surface of the articles has no contact dead angle, and to ensure that the surface of the articles is sterilized in all directions without dead angles, thereby effectively improving the sterilization efficiency of the device. When the piston 411 is displaced, the side frame 502 will drive the bottom frame 505 to follow the displacement. When the piston 411 is displaced toward the stopper 404, the inclined surface of the tooth plate 508 will contact the inclined surface of the ratchet gear 310. At this time, the tooth plate The pressure on 508 will compress the second spring 507 to contract, that is, it will not drive the ratchet gear 310 to rotate. When the piston 411 is pushed outward, the straight edge of the tooth plate 508 will contact the straight edge of the ratchet gear 310. At this time, as the tooth plate 508 moves, the ratchet gear 310 will be driven to rotate. The one-way drive of the ratchet gear 310 by the tooth plate 508 will always drive the ratchet gear 310 to rotate in one reciprocating stroke of the piston 411. Through the one-way rotation of the ratchet gear 310, the ratchet gear 310 drives the first rotating shaft 304 to rotate through the connection of the second rotating shaft 307, the second pulley 308, the belt 309 and the first pulley 306. When the first rotating shaft 304 rotates, the scraper 305 can be driven to rotate accordingly.During the continuous operation of the device, the scraper 305 will be driven to rotate in one direction. The rotation of the scraper 305 can scrape and collect the sewage and dirt at the bottom of the guide surface 303, so that the sewage and dirt are scraped and collected to the surface of the scraper 305. After the sterilization process is completed, all the dirt is scraped and collected to the scraper 305, avoiding the problem of dirt adhering to the bottom of the closed box 301 due to high temperature and being difficult to clean.

[0024] Embodiment 2: Figure 4 , Figure 6 and Figure 7 As shown, a plurality of dampers 407 are evenly and fixedly connected to the rear surface of the closing plate 401, a first spring 408 is sleeved on the outer surface of the plurality of dampers 407, a connecting plate 409 is fixedly connected between the end surfaces of the plurality of dampers 407, a connecting rod 410 is fixedly connected to the front surface of the connecting plate 409, and the end surface of the connecting rod 410 is fixedly connected to the rear surface of the piston 411.

[0025] According to the use steps of the present invention, when the connecting plate 409 is displaced, the connecting plate 409 will drive the damper 407 and the first spring 408 to be compressed or stretched. The setting of the damper 407 can play a buffering role, thereby preventing the piston 411 from moving too fast and affecting the displacement stability of the closing component 3 and the toggle component 5, thereby improving the stability of the device operation.

[0026] Embodiment 3: Figure 4 and Figure 5 As shown, a guide surface 303 is fixedly connected to the bottom of the closed box 301 , the guide surface 303 matches the positions of a plurality of supports 607 , and a first rotating shaft 304 is rotatably connected to the center of the bottom of the guide surface 303 .

[0027] The use steps of the present invention are as follows: through the setting of the guide surface 303, the shape of the guide surface 303 is circular at the center, and the outer side near the center is a downward inclined arc surface, which can facilitate the collection of sewage above, so that the sewage flows to the center and is conveniently scraped and collected by the scraper 305, thereby improving the cleaning efficiency.

[0028] The effect and working principle of the whole mechanism are as follows: when the pulsating vacuum sterilizer is used, the articles to be sterilized are placed in the closed box 301 by opening the cabinet door 2, and the operation of the pulsating vacuum sterilizer causes the closed box 301 to be in a cycle of evacuating vacuum and passing steam. After multiple alternating operations of evacuating vacuum and passing steam, the sterilization of the articles is completed. Multiple alternating operations of evacuating vacuum and passing steam in the closed box 301 cause the internal air pressure of the closed box 301 to be in a high-low pressure switching state. Under the change of air pressure, the driving component 4 can be driven to move. The movement of the driving component 4 can drive the toggle component 5, the placement component 6 and the closed component 3 to cooperate in moving in the closed box 301. With the movement of the placing component 6, the articles placed in the closed box 301 can be moved up and down to avoid the sterilization dead corners caused by the articles being left still for a long time. The movement of the closing component 3 can scrape off the dirt at the bottom of the closed box 301 to avoid the dirt adhering and condensing, which makes cleaning difficult. When the sterilization process begins, the side frame 604 is pulled out of the closed box 301, and the side frame 604 is moved out of the closed box 301 together with the multiple limit rods 605, the limit seat 606, the support 607, the baffle 608 and the round block 609. At this time, the articles to be sterilized are placed above the multiple baffles 608, and the multiple baffles 608 cooperate to provide support for the bottom of the articles. The baffles 610 on both sides provide support to complete the sterilization process. After the items to be sterilized are placed, the side frame 604 is sent back into the closed box 301. The side frame 604 can be inserted along the slot 602 through the connection of the plug block 603, so that the side frame 604 and the fixed frame 601 are spliced ​​and placed. At this time, the side frame 604 is inside the closed box 301, and the placement of the items to be sterilized is completed. At this time, the cabinet door 2 is closed, and the pulsating vacuum sterilizer is started to start the sterilization process. At this time, the closed box 301 starts to be vacuumed. During the vacuuming, the air pressure inside the closed box 301 is reduced. Through the connection of the barrel 405, a closed space is formed between the barrel 405, the piston 411 and the closed box 301. Therefore, when the air pressure in the closed box 301 changes, the piston 411 will be displaced, and the air pressure in the closed box 301 will be reduced. When lowered, the piston 411 will be displaced toward the side plate 403. The setting of the stopper 404 can block and limit the displacement of the piston 411. After the vacuum is evacuated in the closed box 301, the high pressure state is switched inside the closed box 301. At this time, steam is input into the closed box 301, so that the inside of the closed box 301 is in a state of high temperature and high pressure. When the air pressure in the closed box 301 rises, the piston 411 will be pushed outward. When the piston 411 is displaced, the connection plate 409 will be driven to follow the displacement through the connection of the connecting rod 410. When the connecting plate 409 is displaced, the setting of the plug rod 412 can support and limit the displacement of the connecting plate 409, that is, it supports and limits the displacement of the piston 411.The stability of the displacement state of the piston 411 is ensured. When the connecting plate 409 is displaced, the connecting plate 409 will drive the damper 407 and the first spring 408 to be compressed or stretched. The setting of the damper 407 can play a buffering role to prevent the piston 411 from moving too fast and affecting the stability of the displacement of the closing component 3 and the toggle component 5, thereby improving the stability of the operation of the device. When steam is introduced into the closing box 301 to push the piston 411 outward, the piston 411 can drive the side frame 502 to follow the displacement through the connection with the fixed rod 501. When the side frame 502 is displaced, it can be connected with the slider 503 and move along the slide rail 302, that is, the movement of the side frame 502 is controlled by the cooperation between the slide rail 302 and the slider 503. The movement plays a role of supporting and limiting. At this time, the side frame 502 will drive the wave plate 504 to follow the displacement. When the wave plate 504 is in a static state, the wave plate 504 can provide support for the multiple round blocks 609 on the top. Under the wave shape at the top of the wave plate 504, the multiple round blocks 609 will be in a staggered state of high and low positions. The different heights of the multiple round blocks 609 can make the height positions of the blocking rod 608 different. At this time, since an object is placed above the blocking rod 608, the multiple blocking rods 608 in a higher state will contact the bottom of the object to provide support. When the wave plate 504 is displaced, the supporting state of the top round block 609 will change, so the position of the blocking rod 608 will change, and the piston 41 After being completely pushed out under the change of air pressure, the setting of the retaining ring 406 provides blocking and limiting for the piston 411. At this time, the wave plate 504 is displaced in place. After the wave plate 504 is displaced, the supporting state of the round block 609 will change. The round block 609 originally at a high position will correspond to the concave position of the wave plate 504, and the round block 609 originally at a low position will correspond to the arc-shaped wave block position of the wave plate 504. At this time, the supporting state of the object can be changed, and the retaining rod 608 that originally provided support moves down, and the other retaining rods 608 move up to provide support for the object. At this time, under the displacement of the retaining rod 608, the placement of the object will shake, thereby causing the original bottom contact position of the object to change, and the blocked position will be exposed. To carry out sterilization, under multiple changes in air pressure inside the closed box 301, the position of the article can be moved multiple times to ensure that the bottom support surface of the article has no contact dead angle, and to ensure that the surface of the article is sterilized in all directions without dead angles, effectively improving the sterilization efficiency of the device. When the wave plate 504 is displaced to change the position of the round block 609, the round block 609 will drive the support 607 to move up and down, and the support 607 can be displaced along the limit rod 605 through the connection of the limit seat 606, which plays a supporting and limiting role in the up and down displacement of the support 607 and the stop rod 608. When the piston 411 is displaced, the side frame 502 will drive the bottom frame 505 to follow the displacement. When the piston 411 is displaced toward the stop block 404,The inclined surface of the toothed plate 508 will contact the inclined surface of the ratchet gear 310. At this time, the toothed plate 508 will be compressed to compress the second spring 507 to contract, that is, the ratchet gear 310 will not be driven to rotate. When the piston 411 is pushed outward, the straight edge of the toothed plate 508 will contact the straight edge of the ratchet gear 310. At this time, as the toothed plate 508 moves, the ratchet gear 310 will be driven to rotate. The one-way drive of the ratchet gear 310 by the toothed plate 508 will always drive the ratchet gear 310 to rotate in one reciprocating stroke of the piston 411. Through the one-way rotation of the ratchet gear 310, the ratchet gear 310 drives the first rotating shaft 304 to rotate by connecting the second rotating shaft 307, the second pulley 308, the belt 309 and the first pulley 306. When the rotating shaft 304 rotates, the scraper 305 can be driven to rotate accordingly. During the continuous operation of the device, the scraper 305 will be driven to rotate in one direction. The rotation of the scraper 305 can scrape and collect the sewage and dirt at the bottom of the guide surface 303, so that the sewage and dirt are scraped and collected to the surface of the scraper 305. After the sterilization process is completed, all the dirt is scraped and collected to the scraper 305, avoiding the problem that the dirt is attached to the bottom of the closed box 301 due to the high temperature state and is difficult to clean. Through the setting of the guide surface 303, the shape of the guide surface 303 is circular at the center, and the outer side near the center is a downward inclined arc surface, which can facilitate the collection of sewage above, so that the sewage flows to the center and is convenient for being scraped and collected by the scraper 305, thereby improving the cleaning efficiency.
