Description

Technical Field

[0001] This utility model relates to the field of sterilization equipment technology, and in particular to a high-pressure steam sterilization device. Background Technology

[0002] High-pressure steam sterilization uses high temperature and high pressure to kill not only common bacteria and fungi, but also spores and endospores. It is the most reliable and widely used physical sterilization method.

[0003] A portable high-pressure steam sterilization device, with publication number CN213911471U, utilizes four casters mounted on the piston rods of four electrically operated telescopic rods. The piston rods of these rods move to propel the casters, supporting the chamber and allowing for easy movement. Furthermore, shock-absorbing springs within the U-shaped base ensure smooth movement, preventing damage to internal components from shaking. This portable high-pressure steam sterilization device features a novel structure and is easy to move.

[0004] In their daily work, the inventors discovered that the two storage plates inside the aforementioned high-pressure steam sterilization equipment are fixedly connected to the inner wall of the chamber, which means that the position of the storage plates inside the chamber cannot be adjusted, resulting in poor flexibility in loading items. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure steam sterilization device to solve the problems mentioned above in the background technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure steam sterilization device, comprising a chassis, wherein a door and a control panel are fitted to the side of the chassis via hinges, a storage box is placed on the bottom of the chassis and a heating tube is fitted to the inner wall of the storage box, a temperature sensor is fixedly installed on the inner wall of one side of the chassis, and the heating tube and the temperature sensor are electrically connected to the control panel, and an adjustment device for adjusting the internal storage space layout is provided between the inner walls of the two sides of the chassis, the adjustment device comprising multiple mounting rails fixedly installed on the inner walls of the two sides of the chassis, and a shelf and a ventilation slot provided on the surface of each pair of mounting rails are slidably installed between them.

[0007] Preferably, the adjustment device further includes a groove formed on the side of the shelf and a sliding plate that slides on the inner wall.

[0008] Preferably, the surface of the slide plate is fixedly mounted with a plug rod, and the inner wall surface of multiple mounting rails on one side of the chassis is provided with a plug hole that matches the plug rod.

[0009] Preferably, the adjustment device further includes a support plate fixedly installed on the side of the shelf, and a first spring is fixedly installed between the support plate and the slide plate.

[0010] The aforementioned components achieve the following effect: they allow the shelf and the mounting rail to be connected together by assembly, thus enabling the shelf and the mounting rail to be disassembled and separated. This allows for the selection of adding or removing shelves according to the size of the items, thereby increasing the flexibility of the shelf for loading items.

[0011] Preferably, a mounting base and an exhaust pipe that are movably installed inside the top surface of the chassis are fixedly mounted thereon. The mounting base and the chassis are interconnected. A plug is inserted inside the exhaust pipe. A pressure gauge is fixedly mounted on the outer wall surface of the exhaust pipe. The pressure gauge is electrically connected to the control panel.

[0012] The effect achieved by the above components is that the pressure gauge facilitates the detection of the internal pressure of the machine, so that when the pressure decreases, the door can be opened to retrieve items, thus avoiding the possibility of workers being scalded by high-temperature steam.

[0013] Preferably, the top surface of the chassis is provided with a limiting device for limiting the exhaust pipe inside the mounting base. The limiting device includes an L-shaped bracket fixedly installed on the top surface of the chassis and a groove provided on its horizontal end surface. A movable plate is slidably connected inside the groove. A limiting rod is fixedly installed on the surface of the movable plate. A positioning cylinder is fitted on the outer wall surface of the exhaust pipe.

[0014] Preferably, the limiting device further includes a through groove formed on the vertical end surface of the L-shaped bracket, and a sliding rod for sliding the sliding plate is fixedly installed between the inner walls of the two ends of the through groove. The sliding plate and the moving plate are hinged together by a hinge plate.

[0015] Preferably, a second spring is fixedly installed on the surface of the sliding plate, and the end of the second spring away from the sliding plate is fixedly connected to the bottom inner wall of the through groove.

[0016] The effects achieved by the above components are as follows: the setting of the limiting rod and the positioning cylinder has the effect of limiting the exhaust pipe inside the mounting base; the setting of the hinge plate has the effect of driving the moving plate to move inside the groove; and the setting of the second spring has the effect of limiting the position of the sliding plate on the surface of the sliding rod.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] In this invention, by setting an adjustment device, the shelf and the mounting rail are connected together by assembly, so that the shelf and the mounting rail can be disassembled and separated. This allows for the selection of adding or reducing the number of shelves according to the size of the items, thereby increasing the flexibility of loading items onto the shelf.

[0025] Example 1, such as Figure 1-5 As shown, a high-pressure steam sterilization device includes a casing 1. The surface of the casing 1 is fitted with a door 4 via hinges, and a control panel 8 is fitted to its side. A storage box 9 is placed on the bottom surface of the casing 1, and a heating tube 10 is fitted to its inner wall. A temperature sensor 11 is fixedly installed on the inner wall surface of one side of the casing 1. The heating tube 10 and the temperature sensor 11 are electrically connected to the control panel 8. An adjustment device 2 for adjusting the layout of its internal storage space is provided between the inner walls of the two sides of the casing 1.

[0026] Reference Figure 3-5As shown in this embodiment: the adjustment device 2 includes multiple mounting rails 21 fixedly installed on the inner wall surfaces of both sides of the chassis 1. A shelf 22 and a ventilation groove 23 are slidably installed between each pair of mounting rails 21. The adjustment device 2 also includes a sliding groove 24 on the side of the shelf 22 and a sliding plate 25 that slides on the inner wall. A rod 26 is fixedly installed on the surface of the sliding plate 25. The inner wall surfaces of the multiple mounting rails 21 on one side of the chassis 1 are provided with insertion holes 27 that match the rods 26. The adjustment device 2 also includes a support plate 28 fixedly installed on the side of the shelf 22. A first spring 29 is fixedly installed between the support plate 28 and the sliding plate 25, so that the shelf 22 and the mounting rails 21 are connected together by assembly, thereby allowing the shelf 22 and the mounting rails 21 to be disassembled and separated. This allows the number of shelves 22 to be increased or decreased according to the size of the items, thereby increasing the flexibility of loading items onto the shelf 22.

[0027] Reference Figure 1-2 As shown in this embodiment: a mounting base 5 and an exhaust pipe 6 are fixedly installed on the top surface of the chassis 1. The mounting base 5 and the chassis 1 are interconnected. A plug is inserted inside the exhaust pipe 6. A pressure gauge 7 is fixedly installed on the outer wall surface of the exhaust pipe 6. The pressure gauge 7 is electrically connected to the control panel 8. The pressure gauge 7 is set to facilitate the detection of the pressure inside the chassis 1. When the pressure decreases, the door 4 can be opened to take out items, avoiding the possibility of workers being scalded by high-temperature steam.

[0028] Reference Figure 2-4 As shown in this embodiment: The top surface of the chassis 1 is provided with a limiting device 3 to limit the exhaust pipe 6 inside the mounting base 5. The limiting device 3 includes an L-shaped bracket 301 fixedly installed on the top surface of the chassis 1 and a groove 302 opened on its horizontal end surface. A movable plate 303 is slidably connected inside the groove 302. A limiting rod 304 is fixedly installed on the surface of the movable plate 303. A positioning cylinder 305 is fitted on the outer wall surface of the exhaust pipe 6. The limiting device 3 also includes a through groove 306 opened on the vertical end surface of the L-shaped bracket 301. A sliding rod 307 for sliding plate 308 is fixedly installed between the inner walls of the two ends of the through groove 306. The sliding plate 308 and the movable plate 303 are hinged by a hinge plate 309. A second spring 310 is fixedly installed on the surface of the sliding plate 308. The end of the second spring 310 away from the sliding plate 308 is fixedly connected to the bottom inner wall of the through groove 306.

[0029] Working principle: When the number of shelves needs to be reduced or increased according to the size of the items, firstly, slide the slide plate 25, causing it to move inside the slide groove 24. This movement compresses the first spring 29. Simultaneously, the movement of the slide plate 25 also moves the insertion rod 26, causing it to move out of the insertion hole 27. This separation of the insertion rod 26 and insertion hole 27 removes the constraint between the shelf 22 and the mounting rail 21, allowing the shelf 22 to be moved out of the mounting rail 21, thus adding two adjacent shelves. The distance between the shelves 22 facilitates the placement of taller items, thereby improving the flexibility of the device in loading items. Once the number of shelves 22 is adjusted, items can be placed on their surfaces, and the door 4 is closed. Then, the heating element 10 is activated via the control panel 8. The heating element 10 moves to heat the water inside the storage tank 9, generating high-temperature steam to sterilize the items. The pressure gauge 7, through the exhaust pipe 6, detects the pressure inside the casing 1, while the temperature sensor 11 detects the temperature inside the casing 1. When the temperature reaches a preset value... The data is sent to the control panel 8, which controls the heating element 10 to shut off. After sterilization is complete, the plug is removed from the exhaust pipe 6 to release the vent. Then, the pressure gauge 7 is observed; when the pressure on the gauge decreases to a certain level, the door 4 can be opened to remove the sterilized items. If the pressure gauge 7 is damaged by the high-temperature steam and requires maintenance or replacement, first slide the sliding plate 308, causing it to move on the surface of the sliding rod 307. This movement of the sliding plate 308 on the surface of the sliding rod 307 will stretch the second spring 310. Simultaneously, the movement of the sliding plate 308 on the surface of the sliding rod 307 also drives the hinge plate 309 to move. The movement of the hinge plate 309 pulls the moving plate 303 to move inside the groove 302. The movement of the moving plate 303 inside the groove 302 drives the limiting rod 304 to move. The movement of the limiting rod 304 causes it to move out of the positioning cylinder 305. The separation of the limiting rod 304 and the positioning cylinder 305 causes the exhaust pipe 6 to lose its limit inside the mounting base 5. At this time, the exhaust pipe 6 can be removed from the inside of the mounting base 5, and then the pressure gauge 7 on the exhaust pipe 6 can be maintained, further improving the practicality of the device.
