Description

Technical Field

[0001] This utility model relates to the field of micro pressure cooker technology, and in particular to a micro pressure enamel cooker. Background Technology

[0002] Pressure cookers are a relatively new product, which can be categorized into pressure cookers, pressure frying pans, etc. Pressure cookers typically operate at pressures below 1.2 atmospheres. Under this pressure, food cooks more easily than in a regular pot, and the lid can be opened at any time during operation. The water ripple coating is a ceramic coating, providing far superior protection to cast iron pots compared to non-stick coatings. Furthermore, it does not produce harmful leaching substances due to high temperatures during cooking, and it has good acid and alkali resistance, preventing chemical reactions with food. Compared to regular non-stick pots, it is both durable and safe.

[0003] Traditional enamel pots rely on simple gravity sealing between the pot body and lid. Their sealing performance is limited by processing precision and material deformation. In actual use, the pressure inside the pot is usually below 5 kPa, which is difficult to meet the micro-pressure requirements of different ingredients. For example, beef requires 15-20 kPa pressure to achieve rapid tenderization, while leafy green vegetables are prone to over-softening and nutrient loss under pressure exceeding 8 kPa. Traditional pressure cookers have a fixed pressure relief valve to achieve single pressure control, which cannot be flexibly adjusted according to the type of ingredients.

[0004] Therefore, it is urgent to improve the micro-pressure enamel pot to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a micro-pressure enamel pot. By tightening the bolt to pre-tighten the spring, the elastic force applied by the spring to the valve core can be adjusted. When the pressure inside the pot exceeds the set value, steam pushes open the valve core and is discharged from the steam outlet on the side of the regulating valve to release pressure. The pressure inside the pot body and the lid can be flexibly adjusted according to the type of food, greatly improving the applicability of the micro-pressure pot.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A micro-pressure enamel pot includes a pot body and a pot lid. The pot lid is rotatably mounted above the pot body. A pressure relief port is fixedly installed on the pot lid. An adjusting valve is fixedly installed on the upper end of the pot lid. A handle is fixedly installed on one side of the adjusting valve.

[0008] A sleeve is fixedly installed inside the regulating valve. A bolt is rotatably connected to the regulating valve by a thread. The bottom end of the bolt extends into the inside of the sleeve. A spring is fixedly installed inside the sleeve. A valve core is fixedly connected to the bottom end of the spring. The bottom end of the valve core passes through the sleeve and extends into the inside of the pressure relief port. An air outlet is opened on the side of the regulating valve.

[0009] Preferably, the interior of the pressure relief port is connected to the outside through the air outlet.

[0010] Preferably, the air outlet is located on the side of the regulating valve away from the handle.

[0011] Preferably, an upper pressure plate is fixedly installed at the bottom end of the bolt, and a lower pressure plate is fixedly installed at the upper end of the valve core. The upper pressure plate and the lower pressure plate are respectively disposed at the upper and lower ends of the spring.

[0012] Preferably, the upper pressure plate, the lower pressure plate, and the spring are all disposed inside the sleeve.

[0013] Preferably, the pot lid has an M-shaped cross-section, and a number of evenly distributed condensation droplets are fixedly installed on the inner bottom side of the pot lid.

[0014] Preferably, two lugs are fixedly installed on both sides of the pot body.

[0015] Preferably, the inner bottom side of the pot body is provided with a water ripple coating.

[0016] This utility model has at least the following beneficial effects:

[0017] 1. This utility model can adjust the elastic force applied by the spring to the valve core by tightening the bolt. When the pressure inside the pot exceeds the set value, the steam pushes open the valve core and is discharged from the steam outlet on the side of the regulating valve to release pressure. The pressure inside the pot body and the lid can be flexibly adjusted according to the type of food, which greatly improves the applicability of the micro pressure cooker.

[0018] 2. The design of the upper pressure plate, lower pressure plate, spring, and sleeve in this utility model can provide multi-layer heat insulation. The bolt can be adjusted during cooking to quickly release pressure and avoid burns. The fact that the vent and handle are located on different sides can improve the safety of using the pressure cooker.

[0019] 3. The smooth lid of this utility model allows the steam full of delicious ingredients to circulate effectively. The condensation (used to condense steam and guide it to the pot wall) prevents water droplets from falling directly back onto the food surface and also prevents local dry burning of the pressure cooker, thereby extending the service life of the pressure cooker.

[0026] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] like Figures 1-4 As shown, this embodiment provides a micro-pressure enamel pot, including a pot body 1 and a pot lid 2. The pot lid 2 is rotatably mounted above the pot body 1. A pressure relief port 3 is fixedly installed on the pot lid 2. A regulating valve 4 is fixedly installed at the upper end of the pot lid 2. A handle 5 is fixedly installed on one side of the regulating valve 4. A sleeve 6 is fixedly installed inside the regulating valve 4. A bolt 7 is rotatably connected to the regulating valve 4 by a thread. The bottom end of the bolt 7 extends into the inside of the sleeve 6. A spring 8 is fixedly installed inside the sleeve 6. A valve core 9 is fixedly connected to the bottom end of the spring 8. The bottom end of the valve core 9 passes through the sleeve 6 and extends into the inside of the pressure relief port 3. An air outlet 10 is opened on the side of the regulating valve 4.

[0028] The pressure relief port 3 is located in the center of the pot lid 2, with an 8mm diameter and a polished inner wall. The regulating valve 4 is bolted directly above the pressure relief port 3. The valve body is a brass casting. The sleeve 6 is welded inside the regulating valve 4, with an inner diameter of 12mm and a nickel-plated surface for corrosion protection. The spring 8 is made of 316 stainless steel, with a wire diameter of 1.2mm, a free length of 30mm, and is pre-compressed to 25mm before installation. The valve core 9 has an arc-shaped silicone head at the bottom (temperature resistant to 250℃) and is connected to the lower pressure plate 12 by threads at the top. A pressure plate 11 is welded to the bottom of bolt 7. When screwed into regulating valve 4, it can linearly compress spring 8. Bolt 7 is used to drive the pressure plate 11 to deform spring 8. By tightening bolt 7, spring 8 can be pre-tightened, and the elastic force applied by spring 8 to valve core 9 can be adjusted. When the pressure inside pot body 1 exceeds the set value, steam pushes open valve core 9 and is discharged from the steam outlet 10 on the side of regulating valve 4 to release pressure. The pressure inside pot body 1 and pot lid 2 can be flexibly adjusted according to the type of food, which greatly improves the applicability of micro pressure cooker.

[0029] Furthermore, such as Figures 2-4 As shown, an upper pressure plate 11 is fixedly installed at the bottom of the bolt 7, and a lower pressure plate 12 is fixedly installed at the top of the valve core 9. The upper pressure plate 11 and the lower pressure plate 12 are respectively set at the upper and lower ends of the spring 8. The upper pressure plate 11, the lower pressure plate 12, and the spring 8 are all set inside the sleeve 6. The interior of the pressure relief port 3 is connected to the outside through the air outlet 10. The air outlet 10 is located on the side of the regulating valve 4 away from the handle 5. The arrangement of the upper pressure plate 11, the lower pressure plate 12, the spring 8, and the sleeve 6 can play a multi-layer heat insulation role. The bolt 7 can be adjusted to quickly release pressure during cooking to avoid scalding. The fact that the air outlet 10 is not on the same side as the handle 5 can improve the safety of using the micro pressure cooker. Compared with the smart micro pressure cooker, it has a lower cost and a lower failure rate.

[0030] Specifically, in the initial state, rotating the bolt 7 clockwise moves it downward, the upper pressure plate 11 presses the spring 8, and the spring force is transmitted to the valve core 9 through the lower pressure plate 12, causing its silicone head to tightly seal the pressure relief port 3. For every 90° rotation of the bolt 7, it rises by 1mm, and the spring preload decreases by 0.5kPa. When the steam pressure inside the pot exceeds the spring set value, the valve core 9 is opened, and the steam enters the sleeve 6 through the pressure relief port 3 and is discharged from the steam outlet 10.

[0031] Furthermore, such as Figure 2 As shown, the lid 2 has an M-shaped cross section, and several evenly distributed condensation droplets 13 are fixedly installed on the inner bottom side of the lid 2. The smooth, streamlined lid 2 allows the steam full of delicious food to circulate effectively. The condensation droplets 13 (3mm in diameter and 10mm apart) are used to condense the steam and guide it to the pot wall. On the one hand, this prevents water droplets from falling directly back onto the food surface, and on the other hand, it can also prevent the pressure cooker from drying out in some areas, thereby extending the service life of the pressure cooker.

[0032] In addition, such as Figure 1 As shown, two lugs 14 are fixedly installed on both sides of the pot body 1. The inner side of the lugs 14 is covered with a silicone anti-scalding layer. The inner bottom side of the pot body 1 is provided with a water ripple coating 15. The pot body 1 is made of cast iron sand mold casting and sintered at 820℃. Stainless steel lugs 14 are symmetrically welded on both sides of the pot body 1. The inner side of the lugs 14 is covered with a silicone anti-scalding layer. The gap between the pot body 1 and the lid 2 is 0.01-0.03mm, which has strong airtightness and can preserve the original flavor of the food. The water ripple coating 15 at the bottom can make the food heat more evenly. The lid 2 is a floating design, which can effectively prevent the pot from boiling over.

[0033] like Figures 1-4 As shown, the principle of the micro-pressure enamel pot provided in this embodiment is as follows:

[0034] When in use, tightening bolt 7 causes the upper pressure plate 11 to slide down and pre-tighten the spring 8. The deformation of the spring 8 generates pressure on the lower pressure plate 12, which in turn applies elastic force to the valve core 9. When the pressure inside the pot body 1 exceeds the set value, steam pushes open the valve core 9 and is discharged from the steam outlet 10 on the side of the regulating valve 4 to release pressure. The pressure inside the pot body 1 and the lid 2 can be flexibly adjusted according to the type of food, which greatly improves the applicability of the micro pressure cooker.
