[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figures 1-9 The protective device for a pulsed vacuum sterilizer shown includes a protective box 1 and a door 3 hinged to the front of the protective box 1. The protective box 1 has a receiving component 7 inside, and the pulsed vacuum sterilizer body 6 is placed on the receiving component 7. Air inlets 4 are opened on both sides of the bottom of the protective box 1, and an exhaust port 9 is opened on the back side of the protective box 1. It also includes a heat recovery mechanism 2 for recovering the heat in the gas discharged through the exhaust port 9. The receiving component 7 includes a receiving plate 72 with a placement cavity. One side of the receiving plate 72 is opened, and a baffle 71 is inserted on the receiving plate 72. The pulsed vacuum sterilizer body 6 is placed in the placement cavity.

[0031] The heat recovery mechanism 2 includes a recovery box 21 and an air suction hood 22 fixed on the back side of the protective box 1. The air suction hood 22 covers the exhaust port 9, and an air suction pipe 23 is connected between the air suction hood 22 and the recovery box 21. A partition 28 is installed inside the recovery box 21, and a heat absorption chamber is formed above the partition 28. A heat absorption pipe 27 is installed in the heat absorption chamber. A fan 210 communicating with the heat absorption chamber is installed at the bottom of the partition 28. Air outlets 26 are opened on both sides of the bottom of the recovery box 21, and a medium inlet valve 24 and a medium outlet valve 25 communicating with the two ends of the heat absorption pipe 27 are installed on one side of the recovery box 21.

[0032] When in use, first open the door 3, then place the pulsed vacuum sterilizer body 6 on the receiving plate 72, and insert the baffle 71 into the receiving plate 72 to fix the pulsed vacuum sterilizer body 6. Then close the door 3 to complete the installation of the pulsed vacuum sterilizer body 6. During the operation of the pulsed vacuum sterilizer body 6, the protective box 1 protects the pulsed vacuum sterilizer body 6. The air inlet 4 and the exhaust 9 can be used to dissipate heat from the pulsed vacuum sterilizer body 6 to ensure the normal operation of the pulsed vacuum sterilizer body 6.

[0033] Furthermore, during the heat dissipation process, the medium inlet valve 24 can be opened to introduce the heat-absorbing medium into the heat-absorbing pipe 27. Then, the air in the heat-absorbing chamber is drawn out by the fan 210, so that the heat-absorbing chamber forms a negative pressure state. The gas discharged from the exhaust port 9 is then drawn into the heat-absorbing chamber through the suction pipe 23 and the suction hood 22. At this time, the gas comes into contact with the heat-absorbing pipe 27 and absorbs the heat in the gas through the heat-absorbing medium in the heat-absorbing pipe 27. Subsequently, the gas is discharged through the exhaust port 26 under the action of the fan 210, and the heat-absorbing medium is discharged through the medium outlet valve 25 for external use. This realizes the recovery of heat in the gas, avoids the waste of resources, and prevents thermal pollution to the ambient air. This achieves the effect of energy saving and environmental protection, which is beneficial to the operation of the pulsed vacuum sterilizer body 6.

[0034] It should be noted that the heat-absorbing medium in this embodiment can be cold water. When the hot gas comes into contact with the heat-absorbing tube 27, the cold water absorbs the heat in the gas and forms hot water, which can be used externally. Therefore, the heat in the gas can be recovered.

[0035] Furthermore, to facilitate the fan 210 in drawing the gas out of the heat absorption chamber, such as... Figure 6 As shown, ventilation holes are provided on the partition 28, and a filter plate 29 is installed inside the ventilation holes.

[0036] Furthermore, in order to reduce noise during the operation of the pulsed vacuum sterilizer body 6, such as... Figures 3-6 As shown, a first noise reduction component 5 is provided on both sides of the inner wall of the protective box 1, and a second noise reduction component 10 is provided on the top of the inner wall of the protective box 1 and the bottom of the shock-absorbing plate 81. Specifically, both the first noise reduction component 5 and the second noise reduction component 10 include a noise reduction plate, which is filled with sound-absorbing cotton and has a number of sound-absorbing holes evenly distributed on it. The structure and principle of the first noise reduction component 5 and the second noise reduction component 10 are existing technologies, which can be referred to in the prior art (announcement number: CN219423341U, name: protection device for pulsed vacuum sterilizer), and will not be described in detail here.

[0037] Meanwhile, in this embodiment, such as Figures 3-6 as well as Figure 8 and Figure 9As shown, the protective box 1 is also equipped with a shock-absorbing component 8, which includes a shock-absorbing plate 81 and two sets of shock-absorbing buffers connected between the bottom of the shock-absorbing plate 81 and the protective box 1.

[0038] Each set of shock-absorbing buffer components includes two support seats 82 symmetrically fixed inside the bottom of the protective box 1, and a connecting seat 85 installed at the bottom of the shock-absorbing plate 81. A slide rod 87 is installed between the two support seats 82, and two damping sleeves 83 are slidably sleeved on the slide rod 87. A connecting rod 86 is hinged between the top of the two damping sleeves 83 and the connecting seat 85. A shock-absorbing spring 84 is connected between the two damping sleeves 83 and the two support seats 82. The shock-absorbing spring 84 is sleeved on the outside of the slide rod 87. The receiving plate 72 is set on the top of the shock-absorbing plate 81.

[0039] During the operation of the pulsating vacuum sterilizer body 6, when the pulsating vacuum sterilizer body 6 vibrates, the damping plate 81 pushes the damping sleeve 83 along the slide rod 87 through the connecting rod 86. Then, the damping sleeve 83 slides along the slide rod 87. At this time, the damping spring 84 buffers the damping sleeve 83. Thus, the vibration generated when the pulsating vacuum sterilizer body 6 is working is alleviated through the cooperation of the damping sleeve 83 and the damping spring 84, so as to reduce the damage of vibration force to the pulsating vacuum sterilizer body 6, help extend the service life of the pulsating vacuum sterilizer body 6, and improve the protection effect of the pulsating vacuum sterilizer body 6.

[0040] Furthermore, limit strips 11 are installed on both sides of the inner wall of the protective box 1, and limit grooves for sliding of the limit strips 11 are provided on both sides of the shock-absorbing plate 81. Based on this, the shock-absorbing plate 81 can be limited, ensuring the stable lifting and lowering of the shock-absorbing plate 81, thereby facilitating the stable shock absorption of the pulsed vacuum sterilizer body 6.

[0041] Additionally, in one embodiment, such as Figure 6 , Figure 8 and Figure 9 As shown, the damping plate 81 is also provided with an adjustment component that drives the receiving plate 72 to move horizontally along its width direction. The adjustment component includes a cavity opened on the damping plate 81 and a lead screw 13 rotatably installed in the cavity. A lead screw seat is threadedly connected to the lead screw 13, and the top of the lead screw seat is fixedly connected to the bottom of the receiving plate 72. One side of the damping plate 81 is recessed inward to form a groove, and a motor 12 that drives the lead screw 13 to rotate is fixed in the groove. Two guide rails 14 are symmetrically installed on the top of the damping plate 81, and a guide rail groove for sliding the two guide rails 14 is opened on the bottom of the receiving plate 72.

[0042] During the installation of the pulsed vacuum sterilizer body 6, the motor 12 drives the lead screw 13 to rotate, causing the lead screw 13 to move along the concave cavity and drive the receiving plate 72 to slide along the guide rail 14 through the guide rail groove. This allows the receiving plate 72 to move horizontally along the width direction of the shock-absorbing plate 81, so that the receiving plate 72 is removed from the protective box 1. Then, the pulsed vacuum sterilizer body 6 is placed on the receiving plate 72. Subsequently, the motor 12 drives the lead screw 13 to rotate in the opposite direction, causing the lead screw 13 to move the receiving plate 72 along the guide rail 14 into the protective box 1 through the lead screw seat. This achieves rapid installation of the pulsed vacuum sterilizer body 6 without the need for manual handling to move the pulsed vacuum sterilizer body 6 into the protective box 1, saving time and effort and greatly reducing the installation difficulty of the pulsed vacuum sterilizer body 6. This facilitates the rapid installation and use of the pulsed vacuum sterilizer body 6.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
