[0002] A high-pressure autoclave, also known as a high-pressure steam autoclave, refers to a device that uses an electric heating wire to heat water to generate steam. The steam is in a sealed pot body, and the steam in the sealed space cannot escape, so the pressure continuously rises, causing the boiling point of water to continuously increase, and thus the temperature inside the pot also increases accordingly. At a pressure of 0.24 MPa, the temperature inside the pot reaches 121 °C. At this steam temperature, various bacteria and their highly heat-resistant spores can be quickly killed, so it is widely used.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6 Figures 1-6 For this utility model, a technical solution is provided: a pressure sterilizer with an auxiliary heat dissipation and anti-scalding structure, including a housing 1, a pot rack 2, a pot body 3, a pot cover 4, a cylinder 5, a heating chamber 6, a connecting pipe 7, an exhaust valve 8, a control panel 9, an exhaust pipe 10, a condenser pipe 11, a support plate 12, a card slot 13, and a sealing strip 14.

[0031] This device has the effect of quickly taking out to prevent scalding, specifically as follows:

[0032] The housing 1 is a hollow square structure. Inside the housing 1, a pot rack 2 is fixedly installed. Inside the pot rack 2, a pot body 3 is arranged. Below the housing 1, a heating chamber 6 is fixedly connected. The heating chamber 6 is a hollow cylindrical structure, and a heating wire is arranged on the inner wall of the heating chamber 6. A connecting pipe 7 is connected between the heating chamber 6 and the housing 1. An exhaust valve 8 is arranged on the upper surface of the housing 1. A control panel 9 is arranged on the upper surface of the housing 1. A temperature and pressure sensor is arranged inside the housing 1 and is connected to the control panel 9. A driving structure is arranged on the surface of the pot body 3. The driving structure uses a cylinder 5 to achieve the quick taking out of the pot body 3. The driving structure includes the pot rack 2. The pot rack 2 is a hollow cylindrical structure, and the surface of the pot rack 2 is a grid structure. One side surface of the pot rack 2 penetrates through the side surface of the housing 1. The pot body 3 is an open-top structure on the upper surface, and the cross-section of the pot body 3 is an inverted arch structure. Convex strips are arranged on the outer surface of the pot body 3. A sliding groove is arranged on the inner wall of the pot rack 2. The convex strips on the outer surface of the pot body 3 are slidably connected to the sliding groove on the inner wall of the pot rack 2. A pot cover 4 is arranged on one side of the pot body 3. An annular convex block is arranged on the surface of the pot cover 4. A cylinder 5 is arranged on one side of the pot cover 4. The cylinder 5 is fixedly installed through a bracket, and the cylinder 5 is flush with the circle of the pot cover 4. The output end of the cylinder 5 is fixedly connected to the surface of the pot cover 4. A card slot 13 is embedded and installed on the side surface of the housing 1. The card slot 13 is a ring structure, and the card slot 13 is snap-fitted with the annular convex block on the surface of the pot cover 4. A sealing strip 14 is fixedly installed on the inner wall of the card slot 13. A support plate 12 is arranged inside the pot body 3. The support plate 12 is a grid structure, and the support plate 12 has two upper and lower layers. The lower support plate 12 is fixedly connected to the inner wall of the pot body 3, and the upper support plate 12 is slidably connected to the inner wall of the pot body 3;

[0033] Such as Figures 1-6As shown in the figure, when sterilizing the product using this device, the cylinder 5 is activated. The cylinder 5 drives the pot body 3 and the pot lid 4 to slide outwards, exposing the upper surface of the pot body 3. Hold the support plate 12 on the upper layer inside the pot body 3 and slide it to one side, exposing the support plate 12 on the lower layer. At this time, the double-layer support plate 12 can be used to support the product. After the product is placed, activate the cylinder 5 again. The cylinder 5 drives the pot body 3 to slide into the interior of the pot rack 2 until the convex block on the surface of the pot lid 4 engages with the card slot 13 on the surface of the outer shell 1. The sealing strip 14 in the card slot 13 seals between the pot lid 4 and the device. At this time, the cylinder 5 tightly fits the pot body 3 and the outer shell 1. Inject water into the heating chamber 6 and activate the heating wire in the heating chamber 6 to generate steam in the heating chamber 6. The steam enters the interior of the outer shell 1 through the connecting pipe 7. Through the control panel 9, the air pressure and temperature inside the outer shell 1 can be monitored by sensors, thereby sterilizing the product. After sterilization is completed, activate the cylinder 5 to separate the pot body 3 from the outer shell 1, eliminating the need to manually remove bolts and avoiding burns during the manual operation process.

[0034] This device has the effect of steam reflux, specifically as follows:

[0035] A steam recovery structure is provided on the upper surface of the outer shell 1. The steam recovery structure is provided with a condensing pipe 11 to condense the steam inside the outer shell 1, achieving the recovery of steam while dissipating heat. The steam recovery structure includes an exhaust pipe 10. The exhaust pipe 10 penetrates the upper surface of the outer shell 1 and is provided with a valve inside the outer shell 1 to control opening and closing. One end of the exhaust pipe 10 is connected to a condensing pipe 11. The condensing pipe 11 is a spiral structure and is installed on one side of the outer shell 1. The other end of the condensing pipe 11 penetrates the side surface of the heating chamber 6, and a water injection pipe is provided on the side surface of the heating chamber 6;

[0036] As Figure 2 shown, after stopping heating, open the valve in the exhaust pipe 10. The steam inside the outer shell 1 enters the interior of the exhaust pipe 10 and flows along the exhaust pipe 10 into the condensing pipe 11. The process of the steam discharging outwards dissipates heat from the interior of the outer shell 1. When the steam moves in the condensing pipe 11, the steam condenses under the cooling effect of the air and flows back into the heating chamber 6 for reuse, avoiding waste of steam.

[0037] Working principle: When using the autoclave with the auxiliary heat dissipation and anti-scalding structure, the outer shell 1 and the pot body 3 are horizontally installed, and the pot body 3 is slidably connected to the pot rack 2 inside the outer shell 1. Place the product to be sterilized on the surface of the support plate 12 inside the pot body 3. Start the cylinder 5, and the cylinder 5 drives the pot body 3 to move inside the pot rack 2 until the pot cover 4 on the surface of the pot body 3 is engaged with the card slot 13 on the surface of the outer shell 1. Start the heating wire inside the heating cavity 6. The water in the heating cavity 6 generates steam, which enters the outer shell 1 along the connecting pipe 7 to sterilize the product. After sterilization is completed, stop heating, open the valve at the exhaust pipe 10, and discharge the steam along the exhaust pipe 10 into the condenser pipe 11. The steam condenses in the condenser pipe 11 and flows back to the heating cavity 6. At this time, start the cylinder 5 again to drive the pot body 3 to move outwards. The pot body 3 is driven by the cylinder 5, so there is no need to manually disassemble the bolts, preventing scalding during operation and increasing the overall practicality.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
