Description

Technical Field

[0001] This utility model relates to the field of sterilization cabinets, and in particular to a circulating pulsed vacuum sterilization cabinet. Background Technology

[0002] The sterilization principle of a pulsed vacuum pressure steam sterilizer is to use a vacuum pump to draw out the cold air inside the sterilizer with the help of water flow, creating a negative pressure state. Then, saturated hot steam is introduced, which quickly penetrates into the interior of the items. This process is repeated 3 or 4 times. Under the action of high temperature and high pressure, the proteins of microorganisms are denatured and coagulated, thus inactivating them and achieving the sterilization requirements.

[0003] During normal use, the cabinet is constantly under positive or negative pressure. Even when the pressure approaches zero, it is still not easy to open directly. This is especially true when there is a malfunction, such as a power outage or a damaged door motor capacitor. Since the opening direction is usually a pulling motion, mainly along the door hinge, it requires the operator to use considerable force. Even if it is opened, the operator may fall due to inertia.

[0004] Therefore, to address the above problems, a circulating pulsed vacuum sterilizer is provided here. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a circulating pulsed vacuum sterilizer, which mainly solves the problem that the cabinet door is not easy to open, especially when the cabinet door cannot be opened normally in the event of a malfunction.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] In the attached diagram, all identical reference numerals refer to the same components.

[0027] Example 1

[0028] like Figure 1-4 As shown, this utility model provides a circulating pulsed vacuum sterilizer, including a cabinet body 1, a recessed part 2 at the front of the cabinet body 1, a cabinet door 3 installed on the inner side of the recessed part 2, a placement compartment 4 at the rear end of the recessed part 2, a connecting part 5 between the cabinet door 3 and the cabinet body 1, a moving track 6 on the surface of the cabinet door 3, insertion strips 7 on both sides of the recessed part 2, and an insertion seat 8 installed on the inner side of the cabinet door 3. The connecting part 5 includes: a fixed seat 9 located on the surface of the cabinet body 1; a rotating shaft 10 located at the end of the fixed seat 9 near the cabinet door 3; a sliding arm 11 slidably connected to the cabinet door 3; and a driving assembly 12 used to move the insertion seat 8 of the cabinet door 3 to extend and retract left and right into the insertion strip 7.

[0029] Its structure is as follows Figure 1-3 As shown, when the cabinet door 3 is closed, the connector strip 7 and the connector seat 8 are interlocked, and the cabinet door 3 does not completely seal the opening of the storage compartment 4. Only after the cabinet door 3 moves horizontally based on the moving track 6 via the drive assembly 12, the connector strip 7 and the connector seat 8 are interlocked and fixed, so that the cabinet door 3 seals the opening of the storage compartment 4. This creates a situation where, when it needs to be opened, it is opened horizontally first in the longitudinal direction to release the internal pressure. That is, when pulling, the force direction is vertical and needs to directly resist atmospheric pressure, while the longitudinal movement only needs to resist friction. This achieves the effect that when the inside is under positive or negative pressure, the pressure can be slowly released by opening horizontally first, and then the cabinet door 3 can be fully opened based on the rotating shaft 10. This is not only suitable for regular use, but also makes it easier to open the cabinet door 3 and take out the internal utensils with less effort when a malfunction occurs.

[0030] The plug-in bases 8 are arranged in pairs on the surface of the cabinet door 3. The cross-sectional area of ​​the cabinet door 3 is smaller than that of the recessed part 2. The surface of the plug-in base 8 is provided with a strip block 13, and the surface of the plug strip 7 is provided with a strip groove 14. The strip block 13 and the strip groove are arranged correspondingly, and the strip block 13 and the strip groove are distributed at equal distances from top to bottom. This allows the strip block 13 to be inserted into the strip groove when the cabinet door 3 moves, thereby fixing the entire cabinet door 3 in the opening of the storage compartment 4.

[0031] The edge of the storage compartment 4 is provided with a concave sealing ring 15, and the plug-in seat 8 is provided with a convex sealing ring 16. The surface of the convex sealing ring 16 is provided with a rubber ring. This makes the concave sealing ring 15 and the convex sealing ring 16 misaligned when not installed. The cross-section of the concave sealing ring 15 is arc-shaped, and the cross-section structure of the convex sealing ring 16 corresponds to that of the concave sealing ring 15. That is, when the cabinet door 3 is moved, the rubber ring of the convex sealing ring 16 will be interference-fitted into the interior of the concave sealing ring 15 to form a sealing effect around the storage compartment 4.

[0032] The drive assembly 12 includes a hydraulic push rod 19 inside the moving track 6. The hydraulic push rod 19 is located inside the moving track 6, and a rear telescopic rod 20 is installed on the right side of the hydraulic push rod 19. The rear telescopic rod 20 is connected to the inner wall of the moving track 6. There is a gap between the hydraulic push rod 19 and the moving track 6. A handle is installed on the upper part of the drive assembly 12, so that the front part of the hydraulic push rod 19 is mainly fixedly connected to the left inner wall of the moving track 6, and the right side is fixedly connected through the rear telescopic rod 20. Since the hydraulic push rod 19 is not directly connected to the moving track 6, the hydraulic push rod 19 can move left and right on the moving track 6 based on the pushing force.

[0033] The sliding arm 11 is slidably connected to the cabinet door 3 through the sliding connection groove 21, and the sliding arm 11 and the fixed seat 9 are rotatably connected through the rotating shaft 10, so that the sliding arm 11 and the cabinet door 3 are embedded in the sliding connection. When the hydraulic push rod 19 is activated, the sliding arm 11, as a sliding fixed bar, can move synchronously and maintain the position of the hydraulic push rod 19, so that the cabinet door 3 can move a certain stroke distance.

[0034] Specifically, when closing the cabinet door 3, the cabinet door 3 is moved to the inside of the recessed part 2 by rotating the shaft 10 as the axis; at this time, the plug strip 7 and the plug seat 8 are interlocked, and the convex sealing strip and the concave sealing strip are also interlocked.

[0035] When the cabinet door 3 is driven by the hydraulic push rod 19 of the drive assembly 12, the sliding arm 11 and the cabinet door 3 remain stationary according to the overall position of the sliding connection groove 21. The cabinet door 3 will move to the left due to the action of the hydraulic push rod 19 until the strip block 13 and the strip groove are interlocked, allowing the interlocking strip 7 and the interlocking seat 8 to be spliced. At the same time, the convex sealing strip and the concave sealing strip will also interlock due to the displacement to form a sealing effect.

[0036] When the cabinet door 3 is opened, the main resistance it encounters during longitudinal translation is static friction against the strip block 13, the strip groove, the convex sealing strip, and the concave sealing strip. This means that after the cabinet door 3 moves slightly, the air inside the storage compartment 4 will balance with the outside, making the cabinet door 3 easier to open. Therefore, whether in conventional opening operations, the drive assembly 12 is placed outside for easier maintenance and repair, or in manual opening operations, the operator can disassemble the drive assembly 12 and manually brake it, allowing the cabinet door 3 to move on the sliding arm 11.

[0037] Example 2

[0038] The difference from Example 1 is that, as Figure 5 As shown, the side wall of the recessed part 2 is provided with a slot 17. The slot 17 and the plug strip 7 are arranged in an alternating manner in terms of their horizontal projections. The slot 17 is located at the edge of the recessed part 2. The cabinet door 3 is provided with a tongue 18 on one side. The tongue 18 corresponds to the position of the slot 17.

[0039] The slot 17 has a trapezoidal cross-section, the tongue 18 has a trapezoidal structure at the end near the slot 17, and a rectangular structure at the end away from the slot 17.

[0040] Specifically, in order to further increase the sealing between the cabinet door 3 and the storage compartment 4, when the cabinet door 3 is moved horizontally, the tongue 18 can be inserted along the slot 17 until the tongue 18 causes the left side of the cabinet door 3 to continuously move downward along the inclined slot 17, so that the left side of the cabinet door 3 can be better sealed; at the same time, when the cabinet door 3 is opened, the tongue 18 can also limit the opening of the cabinet door 3 at the slot 17. For example, when the positive pressure of the storage compartment 4 is large, during the process of the cabinet door 3 moving to the right, the internal positive pressure will continuously push the cabinet door 3 open, and the tongue 18 and the slot 17 will form a limiting effect to prevent the cabinet door 3 from popping open directly.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
