[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1-6 The utility model provides an embodiment: a pulsating vacuum sterilizer, comprising a sterilizer body 1, a sterilization tank 7, a first placement plate 5, two second placement plates 6, a moving mechanism 3, a cleaning mechanism 8, two first sliders 16 and two connecting blocks 17. The sterilization tank 7 is arranged on one side of the front end surface of the sterilizer body 1, and a cabinet door 2 is hingedly arranged on one side of the front end surface of the sterilizer body 1. The lower end surface of the moving mechanism 3 is fixedly arranged on the inner bottom surface of the sterilization tank 7, and the lower end surface of the cleaning mechanism 8 is slidably arranged on the rear side of the upper end surface of the moving mechanism 3. By opening the cabinet door 2, the first placement plate 5 and the two second placement plates 6 in the sterilization tank 7 can be conveniently taken out. During the taking-out process, the three placement plates and the cleaning mechanism 8 are driven to move to the front side by the moving mechanism 3, which reduces the steps of manual operation and is more convenient.

[0036] A bottom plate 18 is slidably provided on the upper end surface of the moving mechanism 3, and support plates 4 are fixedly provided at the four corners of the upper end surface of the bottom plate 18. Positioning plates 9 are slidably penetrated on both sides of the front and rear end surfaces of the two second placement plates 6, and return springs 10 are fixedly provided between the end surfaces of the opposite sides of the multiple positioning plates 9. The first placement plate 5 is fixedly provided on the lower side between the four support plates 4, and the two second placement plates 6 are slidably provided on the upper side and the middle position between the four support plates 4, respectively.

[0037] By setting a fixed first placement plate 5 and two sliding second placement plates 6, the distance between the placement plates can be adjusted according to the size of the placed items, thereby improving practicality. Before placing the items, the two positioning plates 9 on both sides of the second placement plate 6 can be manually pushed toward the middle while holding the second placement plate 6 to move in the vertical direction. When it moves to a suitable position, release the pull on the positioning plate 9. At this time, under the action of the reset spring 10, the positioning plate 9 is pushed into the positioning hole opened in the support plate 4, thereby fixing the second placement plate 6 between the four support plates 4.

[0038] The moving mechanism 3 includes a fixed plate 301, two motors 302 and two second screw rods 303. Second sliders 304 are slidably arranged on both sides of the rear inner wall of the fixed plate 301. The two motors 302 are respectively fixedly arranged on both sides of the rear inner wall of the fixed plate 301. The rear end faces of the two second screw rods 303 are respectively fixedly connected to the output ends of the two motors 302. The two second sliders 304 are respectively threadedly sleeved on the rear sides of the outer end faces of the two second screw rods 303.

[0039] When the two motors 302 are working, they drive the two second screw rods 303 to rotate. During the rotation, the two second screw rods 303 drive the second sliders 304 on the surface to move forward. Through the inner walls of the two second sliders 304 abutting against the surfaces of the two first sliders 16, when the second sliders 304 slide, they drive the first sliders 16 to move together. Through the abutment between the first slider 16 and the inner wall of the bottom plate 18, the bottom plate 18 is driven to slide forward. The bottom plate 18 drives the first placement plate 5 and the two second placement plates 6 to leave the sterilization tank 7 through the four support plates 4.

[0040] The two lower inner walls at the rear sides of the four support plates 4 are each provided with a cavity 12, and a rotating shaft 11 is rotatably arranged between the end faces of the four support plates 4 on the opposite sides of each other, and a first screw rod 14 is rotatably arranged through the top faces of the two cavities 12, and a first bevel gear 13 is fixedly sleeved on the rear sides of the outer end faces of the two rotating shafts 11, and a second bevel gear 15 is fixedly sleeved on the lower sides of the outer end faces of the two first screw rods 14, and the two first bevel gears 13 are respectively meshed and connected with the two second bevel gears 15, and two first sliders 16 are respectively threadedly sleeved on the lower sides of the outer end faces of the two first screw rods 14, and the two The lower sides of the outer end surfaces of the first slider 16 are respectively slidably arranged on the upper inner walls of the two second sliders 304. When the rotating shaft 11 is rotated, the rotating shaft 11 drives the second bevel gear 15 to rotate, and the second bevel gear 15 drives the first bevel gear 13 to rotate, thereby driving the first screw rod 14 to rotate. During the rotation of the first screw rod 14, the first slider 16 on its surface is driven to move upward a short distance. The first slider 16 is still in the inner wall of the second slider 304. When the second slider 304 moves, it can continue to drive the first slider 16 to move to one side.

[0041] The cleaning mechanism 8 includes a cleaning frame 801 and a sponge 802. Both sides of the front end surface of the cleaning frame 801 are provided with connecting grooves 803. The front end surfaces of the two connecting blocks 17 are respectively fixedly connected to the upper sides of the rear end surfaces of the two second sliders 304. The sponge 802 is fixedly sleeved on the outer end surface of the cleaning frame 801. The outer end surfaces of the two connecting blocks 17 are respectively slidably arranged on the lower inner walls of the two connecting grooves 803. After the first slider 16 moves upward for a certain distance, the first slider 16 drives the connecting block 17 integrated with it to slide in the connecting groove 803, so that the connecting Block 17 abuts against the inner wall of the connecting groove 803. When the first slider 16 moves to one side, it drives the cleaning frame 801 to move to one side. When the second screw rod 303 drives the second slider 304 to slide to the frontmost side, the rotating shaft 11 is rotated again. The rotating shaft 11 drives the first slider 16 to leave the inner wall of the second slider 304 through the first bevel gear 13, the second bevel gear 15 and the first screw rod 14. At this time, the bottom plate 18 can be completely removed from the sterilization tank 7, and then the surface of the first placement plate 5 and the two second placement plates 6 can be cleaned.

[0042] Working principle: open the cabinet door 2, then open the two motors 302 to drive the two second screw rods 303 to rotate, and the two second screw rods 303 drive the second sliders 304 on their surfaces to move forward, and through the second sliders 304 and the first sliders 16 abutting against each other, the bottom plate 18 is driven to slide out of the sterilization tank 7, and then the items on the surface of the placement plate are removed. When placing new items, the distance between the placement plates can be adjusted according to the size of the items, by manually pushing the two positioning plates 9 on both sides of the first placement plate 5 toward the middle, while holding the first placement plate 5 to move up and down in the vertical direction, after moving to the appropriate position, release the push on the positioning plates 9, when it is necessary to clean the sterilization tank 7, when the cabinet door 2 is opened, the two rotating shafts 11 are manually rotated, the two first sliders 16 move upward for a distance, and the two first sliders 16 drive the two connecting blocks 17 to move upward together, and then turn on the motor 302, and the bottom plate 18 drives the cleaning frame 801 to move forward together through the connecting block 17.
