Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure sterilization, in particular to a high-pressure sterilization device. Background Art

[0002] An autoclave is a device that uses steam to sterilize at high pressure and is widely used in medical, scientific research and other fields that require a strictly sterile environment.

[0003] The working principle of the autoclave is mainly based on the method of moist heat sterilization. That is, when the sterilization process begins, the heating element in the sterilizer heats the water source to generate steam. In addition, the sterilization chamber is also preheated to a set temperature to ensure that the steam remains high throughout the process. The steam enters the sealed sterilization chamber, and as the amount of steam increases, the pressure and temperature in the chamber gradually rise. Once the required temperature and pressure are reached, the sterilizer will maintain these conditions for a predetermined period of time (usually 15-30 minutes), which is enough to kill most microorganisms, including bacteria, viruses, spores, etc. During this process, high-temperature and high-pressure steam penetrates all surfaces of the sterilized items, including small gaps, and effectively kills the existing microorganisms. After completing the sterilization cycle, the pressure in the chamber is gradually released to allow the steam to be discharged. Then through the drying cycle, ensure that the sterilized items are completely dry before being taken out to prevent the microorganisms from reproducing. After all steps are completed, the items in the sterilizer need to be cooled to a safe temperature for safe removal. The specific reference model is the MLS-830L autoclave.

[0004] The high-pressure sterilizer consists of a cylinder and a cylinder cover, and the cylinder cover is fixed to the upper end of the cylinder by a hook. However, when the high-pressure sterilizer is in use, the pressure in the sterilizer exerts a strong thrust on the cylinder cover. The cylinder cover cannot be guaranteed to be stable by only fixing the cylinder cover by the hook, which easily causes the cylinder cover to separate from the cylinder, resulting in the failure to ensure the sealing of the cylinder. In order to solve the above-mentioned problems, a high-pressure sterilization device is now provided. Utility Model Content

[0019] 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.

[0020] Example

[0021] See also Figure 1-4 This embodiment provides a high-pressure sterilization device, which includes a barrel 1 and a barrel cover 2. The high-pressure sterilization device refers to the high-pressure sterilizer model MLS-830L. The barrel cover 2 is rotatably connected to the upper end of the barrel 1. The upper end of the barrel 1 is provided with a chamber for placing devices to be sterilized. The barrel cover 2 rotates to fit the upper end of the barrel 1 to seal the chamber of the barrel 1. The connection, function, and energy consumption of the barrel 1 and the barrel cover 2 also refer to the high-pressure sterilizer model MLS-830L.

[0022] like Figure 2 As shown, the upper end of the cylinder body 1 is rotatably connected with four hooks, and the lower end of the cylinder cover 2 is provided with four hook grooves, and the cylinder cover 2 can be fixedly covered on the upper end of the cylinder body 1 by hooking the hooks into the hook grooves. However, if the cylinder cover 2 is only fixed by the hooks, after the internal pressure of the cylinder body 1 increases, the stability of the cylinder cover 2 sealing the cylinder body 1 is poor. In order to further increase the stability of the cylinder cover 2 sealing the cylinder body 1, a sliding frame 3 is slidably sleeved on the outer wall of the cylinder cover 2.

[0023] Specifically, both inner side walls of the sliding frame 3 are provided with sliding grooves and multiple through holes, and the through holes and the sliding grooves are interconnected. Second cross bars 21 are fixedly connected to both sides of the cylinder cover 2, and the second cross bars 21 are slidably inserted in the sliding grooves of the sliding frame 3, so that the sliding frame 3 is slidably connected to the cylinder cover 2.

[0024] like Figure 2As shown, multiple first cross bars 11 are fixedly connected to the upper ends of both sides of the cylinder 1, and the multiple first cross bars 11 on the same side are evenly distributed in a straight line, and the spacing between two adjacent first cross bars 11 is consistent with the length of the first cross bars 11. When the cylinder cover 2 is closed on the upper end of the cylinder 1, the first cross bars 11 are also slidably installed in the slide groove of the sliding frame 3.

[0025] When the cylinder cover 2 is covered on the cylinder body 1, the first cross bar 11 and the second cross bar 21 fit together, and the first cross bar 11 enters the slide groove through the through hole of the sliding frame 3, pushing the sliding frame 3 so that the first cross bar 11 is located between two adjacent through holes, thereby limiting the first cross bar 11 to prevent the first cross bar 11 from escaping from the slide groove of the sliding frame 3. After the first cross bar 11 and the second cross bar 21 fit together and are limited by the slide groove of the sliding frame 3, the connectivity between the cylinder cover 2 and the cylinder body 1 can be increased.

[0026] like Figure 2 As shown, the end faces of the cylinder body 1 and the cylinder cover 2 are also fixedly connected with a third cross bar 4. After the cylinder cover 2 is covered on the upper end of the cylinder body 1, the third cross bar 4 of the cylinder body 1 and the third cross bar 4 of the cylinder cover 2 fit each other. Figure 3 As shown, a card slot is provided on the inner wall of the sliding frame 3. After the sliding frame 3 is pushed, the sliding frame 3 is engaged with the outer walls of the two third cross bars 4 through the card slot. The sliding frame 3 limits the two third cross bars 4, further increasing the connectivity between the cylinder cover 2 and the cylinder body 1, and preventing the cylinder cover 2 from separating from the cylinder body 1.

[0027] like Figure 1 and Figure 2 As shown, a handle 6 is fixedly connected to the outer wall of the sliding frame 3, and the sliding of the sliding frame 3 can be controlled by the handle 6. When the sliding frame 3 is pulled so that the first cross bar 11 is aligned with the through hole up and down, the cylinder cover 2 can be driven to rotate through the sliding frame 3.

[0028] During the heating and pressure change process of the sterilization device, some mechanical parts inside, such as the safety valve and the exhaust valve, will cause slight vibrations when they are active. During the pressure rise or fall process, rapid steam release or adjustment will also cause slight vibrations of the equipment. These vibrations cause the sliding frame 3 to slide. In order to fix the sliding frame 3, the sliding frame 3 is provided with a fixing mechanism 5. The fixing mechanism 5 includes a dial plate 51, a block 52 and an elastic member 53, such as Figure 4 As shown, a protrusion is provided at the lower end of the sliding frame 3, and a control groove is opened in the protrusion. The dial plate 51 is fixedly connected to one end of the block 52, and the dial plate 51 and the block 52 are slidably installed in the control groove. The elastic member 53 is also installed in the control groove, and one end of the elastic member 53 is fixedly connected to the block 52. The elastic member 53 is set as a spring, and an elastic force is applied to the block 52 through the elastic member 53, so that one end of the block 52 extends out from the side wall of the protrusion.

[0029] like Figure 2 As shown, a groove is provided on the end face of the cylinder 1, and a clamping hole is provided on the inner side wall of the groove. After the cylinder cover 2 is closed on the upper end of the cylinder 1, the sliding frame 3 can be moved to make the protrusion engage in the groove, and the end of the clamping block 52 extending from the protrusion engages in the clamping hole. By engaging the clamping block 52 in the clamping hole, the protrusion can be limited to prevent the protrusion from escaping from the groove, that is, the sliding frame 3 is fixed.

[0030] When the sliding frame 3 needs to be moved, the shifting plate 51 is shifted to drive the clamping block 52 to slide, so that one end of the clamping block 52 is separated from the clamping hole and retracted into the protrusion, and the sliding frame 3 can be moved at this time.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
