Sterilization device for plant seedling tissue culture

Abstract

This utility model relates to the field of tissue culture technology, specifically a sterilization device for plant seedling tissue culture. It includes a support frame, with an insulated container fixed to the top of the support frame. The insulated container has a lid, and an adjustment component for raising and lowering the internal space is installed inside. A drive component for controlling the raising and lowering of the adjustment component is located at the bottom. By setting up the drive component and the adjustment component, an electric push rod drives a lifting plate to move a water tank up and down, ensuring that the internal space of the insulated container only accommodates the instruments to be sterilized. This avoids heating and pressurizing excess space, thus reaching the target temperature and pressure more quickly and accelerating the overall sterilization speed. After sterilization, the upward movement of the water tank lifts out the culture instruments placed on the net, facilitating their removal. Simultaneously, a scraper ring scrapes off the water vapor condensed on the inner wall of the insulated container, allowing it to flow more quickly into the water tank for subsequent discharge.

Description

Technical Field

[0001] This utility model relates to the field of tissue culture technology, and in particular to a sterilization device for plant seedling tissue culture. Background Technology

[0002] Plant tissue culture, also known as in vitro culture, refers to the technique of isolating the desired tissues, organs, cells, protoplasts, etc. from the plant and inoculating them on a culture medium containing various nutrients and plant hormones under aseptic conditions to obtain regenerated complete plants. The sterilization of the culture equipment is usually completed by high-pressure steam sterilization equipment.

[0003] A high-pressure steam sterilizer disclosed in Chinese Patent Publication No. CN222752336U allows for adjustments to the storage space within the container to accommodate more experimental instruments during a single sterilization process, increasing the number of instruments sterilized at once. However, according to related technologies and existing technologies, the space requiring heating within this high-pressure steam sterilizer remains fixed. Even with only a small number of culture instruments to be sterilized, heating and pressurizing the entire interior space is necessary, requiring a considerable amount of time to reach the target temperature and pressure, thus reducing the overall sterilization speed. Furthermore, heating and pressurizing the excess space reduces energy efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a sterilization device for plant seedling tissue culture.

[0005] The purpose of this utility model is achieved through the following technical solution: a sterilization device for plant seedling tissue culture, including a support frame, a heat preservation barrel fixedly provided on the top of the support frame, a barrel lid installed on the top of the heat preservation barrel, an adjustment component for raising and lowering the internal space of the heat preservation barrel installed inside the heat preservation barrel, a drive component for controlling the raising and lowering of the adjustment component provided at the bottom of the adjustment component, and a heating tube installed inside the adjustment component.

[0006] Preferably, the drive assembly includes an electric push rod fixed to the top of the support frame, the output end of the electric push rod extending upward through the support frame and into the interior of the insulation barrel, a lifting plate fixedly provided at the output end of the electric push rod, a sliding sleeve fixedly provided at the top of the lifting plate, and the sliding sleeve slidably connected to the insulation barrel.

[0007] Preferably, the adjusting component includes a water box slidably installed inside the sliding sleeve, the water box has an inner edge on the inner side of its top, a placement net is installed on the inner edge, the water box has an outer edge on the outer side of its top, and a sealing gasket is fixedly provided at the bottom of the outer edge.

[0008] Preferably, the bucket lid has a circumferential array of multiple latches, the bucket lid is locked to the top of the insulated bucket by the latches, and the bucket lid is provided with a safety valve and a pressure relief valve.

[0009] Preferably, a scraper ring is fixedly provided on the top of the water box, and the top of the scraper ring is conical and fits into the inside of the insulated bucket.

[0010] Preferably, a cavity is provided between the bottom of the water box and the lifting plate for the water box to slide downward.

[0012] Preferably, a drain pipe is fixedly provided at the bottom of the water box.

[0013] Beneficial effects:

[0014] This sterilization device for plant seedling tissue culture, through the setting of drive and adjustment components, uses an electric push rod to drive the lifting plate to move the water tank up and down, so that the space inside the heat preservation barrel can only hold the instruments to be sterilized. When sterilizing a small number of culture instruments, it avoids heating and pressurizing the extra space, thereby reaching the target temperature and pressure more quickly, accelerating the overall sterilization speed, and reducing energy consumption. After sterilization, the upward movement of the water tank can lift the culture instruments placed on the net, making it easier to remove the culture instruments. At the same time, the scraper ring scrapes off the water vapor condensed on the inner wall of the heat preservation barrel, allowing it to flow into the water tank more quickly, making it easier to drain later.

[0024] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, in part of which will be obvious from the description or may be learned by practice of the invention.

[0025] like Figures 1 to 6As shown, a sterilization device for plant seedling tissue culture includes a support frame 1, an insulated container 2 fixedly mounted on top of the support frame 1, a lid 3 mounted on top of the insulated container 2, and multiple latches 4 arranged in a circular array on the lid 3. The lid 3 is locked to the top of the insulated container 2 by the latches 4. The lid 3 is equipped with a safety valve 10 and a pressure relief valve 11. An adjustment component 6 for raising and lowering the internal space of the insulated container 2 is installed inside. A drive component 5 for controlling the raising and lowering of the adjustment component 6 is located at the bottom of the adjustment component 6. A heating tube 7 is installed inside the adjustment component 6. In use, first open the latches 4 to remove the lid 3, and pour pure water into the adjustment component 6. Then, the drive component 5 controls the raising and lowering of the adjustment component 6 to adjust the space inside the insulated container 2 so that it can just accommodate the culture instruments to be sterilized, and then place the culture instruments on the adjustment component 6. Then, the lid 3 is closed again and secured with the latch 4, thus sealing the top of the insulated container 2. Finally, the heating tube 7 heats the pure water in the regulating component 6. The steam generated by the heating continuously pressurizes the inside of the insulated container 2 until it reaches the threshold of the safety valve 10. The safety valve 10 automatically releases the pressure, maintaining the required pressure inside the container, thereby sterilizing the culture instruments with high-pressure steam. During this process, the space inside the insulated container 2 only accommodates the instruments to be sterilized, avoiding heating and pressurizing the extra space. When sterilizing a small number of culture instruments, the required temperature and pressure can be reached quickly, accelerating the sterilization speed and reducing energy consumption. After sterilization, the pressure is first released through the pressure relief valve 11, then the latch 4 is opened to remove the lid 3, and then the drive component 5 controls the regulating component 6 to move upward, lifting the culture instruments upward for easy removal.

[0026] like Figure 3 and Figure 4 As shown, the drive assembly 5 includes an electric push rod 51 fixed to the top of the support frame 1. The output end of the electric push rod 51 extends upward through the support frame 1 and into the interior of the insulation barrel 2. A lifting plate 52 is fixedly provided at the output end of the electric push rod 51. A sliding sleeve 53 is fixedly provided at the top of the lifting plate 52. The sliding sleeve 53 is slidably connected to the insulation barrel 2. The support frame 1 supports the extension and retraction of the electric push rod 51, which drives the adjustment assembly 6 to move up and down through the lifting plate 52 and the sliding sleeve 53, thereby adjusting the space inside the insulation barrel 2.

[0027] like Figures 3 to 6As shown, the adjusting assembly 6 includes a water box 61 slidably installed inside the sliding sleeve 53. The water box 61 has an inner edge 62 on its top inner side, on which a placement net 63 is installed. The water box 61 also has an outer edge 64 on its top outer side, with a sealing gasket 65 fixedly installed at the bottom of the outer edge 64. The sealing gasket 65 is fitted over the outside of the water box 61, and its outer side is in contact with the inner wall of the insulation container 2. The bottom of the sealing gasket 65 contacts the top of the sliding sleeve 53. A drain pipe 8 is fixedly installed at the bottom of the water box 61. A cavity 12 for the water box 61 to slide downwards is provided between the bottom of the water box 61 and the lifting plate 52. A scraper ring 9 is fixedly installed at the top of the water box 61. The top of the scraper ring 9 is conical and fits against the inside of the insulation container 2. The electric push rod 51 extends and retracts, driving the water box 61 up and down via the lifting plate 52, adjusting the space inside the insulation container 2 so that it can just accommodate the culture instruments to be sterilized. During sterilization, this avoids damaging the excess space. Heating and pressurization can quickly reach the required temperature and pressure when sterilizing a small number of culture instruments, thus accelerating the overall sterilization speed and reducing energy consumption. During the sterilization process, the pressure difference between the inside and outside of the insulated container 2 will push the water box 61 to compress the cavity 12 and move downward along the inside of the sliding sleeve 53, causing the water box 61 to move downward along its outer edge 64. This, in conjunction with the top of the sliding sleeve 53, compresses and deforms the sealing gasket 65, making it fit more closely to the wall of the insulated container 2, thereby enhancing the seal between the top of the water box 61 and the insulated container 2. After sterilization, the electric push rod 51 extends and moves the water box 61 upward through the lifting plate 52, allowing the water box 61 to lift the culture instruments on the placement net 63 for easy removal. At the same time, the scraper ring 9 on the top of the water box 61 can scrape off the water vapor condensed on the inner wall of the insulated container 2, allowing it to flow into the water box 61 more quickly and be discharged through the drain pipe 8 later.

[0028] The work process is as follows:

[0029] S1: As Figures 1 to 4 As shown, when using it, first open the latch 4 to remove the lid 3, and pour pure water into the water box 61. Then, the support frame 1 supports the electric push rod 51 to extend and retract, and the lifting plate 52 drives the water box 61 to move up and down, adjusting the space inside the heat preservation bucket 2 so that it can just accommodate the culture instruments to be sterilized. Place the culture instruments on the placement net 63, and then close the lid 3 again and fix it with the latch 4, thereby sealing the top of the heat preservation bucket 2.

[0030] S2: As Figure 1 and Figure 4 As shown, after the insulated container 2 is sealed, the heating tube 7 heats the pure water in the water box 61. The steam generated by heating continuously increases the pressure inside the insulated container 2 until it reaches the threshold of the safety valve 10. The safety valve 10 automatically releases the pressure to maintain the required pressure inside the container, thereby sterilizing the culture instruments with high-pressure steam.

[0031] S3: As Figure 3 and Figure 4 As shown, during the sterilization process, the pressure difference inside and outside the heat preservation barrel 2 will push the water box 61 to compress the cavity 12 and move downward along the inside of the sliding sleeve 53, causing the water box 61 to move downward along the outer edge 64. This, in conjunction with the top of the sliding sleeve 53, squeezes and deforms the sealing gasket 65, making it fit more closely to the wall of the heat preservation barrel 2, thereby enhancing the sealing between the top of the water box 61 and the heat preservation barrel 2.

[0032] S4: As Figure 6 As shown, the space inside the insulated container 2 can only hold the instruments to be sterilized, avoiding heating and pressurizing the extra space. When sterilizing a small number of culture instruments, the required temperature and pressure can be reached more quickly, accelerating the overall sterilization speed and reducing energy consumption.

[0033] S5: As Figure 1 and Figure 4 As shown, after sterilization, the pressure inside the insulated bucket 2 is first released through the pressure relief valve 11, then the buckle 4 is opened and the bucket lid 3 is removed. Then the electric push rod 51 extends and drives the water box 61 to move upward through the lifting plate 52, so that the water box 61 lifts out the culture instrument placed on the net 63, making it easy to remove.

[0034] S6: As Figures 4 to 6 As shown, the scraper ring 9 on the top of the water box 61 can scrape off the water vapor condensed on the inner wall of the heat preservation bucket 2, allowing it to flow into the water box 61 more quickly and be discharged through the drain pipe 8 later.

[0035] In this application, the latch 4, heating tube 7, safety valve 10 and pressure relief valve 11 are known technologies in this field, therefore their specific structures and working principles are not described in detail.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
