Description

Technical Field

[0001] The utility model relates to the field of kitchen utensils, in particular to a micro-pressure cooker cover and a micro-pressure cooker. Background Art

[0002] When cooking with a pot, the higher the pressure in the pot, the shorter the cooking time and the more energy-saving it is. To this end, the industry has developed various pressure cookers to achieve energy-saving purposes. However, the production of pressure cookers requires that the cookware manufacturer has the corresponding production qualifications, and the pressure standard of the pressure cooker is above 80.5KPa. Cases of pressure cookers exploding and injuring people are not uncommon. Therefore, the use of pressure cookers involves certain risks.

[0003] To this end, technicians in this field have developed a micro-pressure cooker with a cooking pressure lower than 12.5KPa. Due to the cooking needs and cooking habits of users, different users will choose micro-pressure cookers with different pressures, but this requires manufacturers to develop different micro-pressure cooker covers to achieve different pressures. The pressure of the micro-pressure cooker is entirely controlled by the air valve. Changing the opening and closing pressure of the air valve often leads to different materials used in the air valve or the process of key components. For example, in the prior art, different springs are often used to control the opening and closing pressure of the air valve, and the springs with different opening and closing pressures have different heat treatment methods or different wire diameters or different materials. Therefore, the overall cost of the air valve is relatively high, but in order to meet the needs of different users, it is necessary to order air valves of different specifications in small batches, which ultimately leads to an increase in the manufacturer's parts inventory and an increase in procurement costs. In addition, the spring is also prone to rust and changes in elasticity coefficient in a high-temperature steam environment and a humid environment, which results in the user being able to meet the pressure requirements when first used, but the pressure drops after 1 to 2 years of use.

[0004] Therefore, those skilled in the art hope to obtain a micro-pressure cooker cover, which is provided with an air valve, and the air valve has a simple structure, a low price, and can easily adjust the opening and closing pressure. Utility Model Content

[0025] Reference Figures 1 to 5 , these are some embodiments of the utility model:

[0026] A micro-pressure cooker includes a pot body 2 and a micro-pressure cooker cover. The micro-pressure cooker cover includes a cover body 11 and a sealing member 12 arranged on the cover body 11. The cover body 11 is provided with a pressure relief hole. The pressure relief hole is provided with a gravity air release valve assembly. A sealing collar 13 is provided between the gravity air release valve assembly and the pressure relief hole. The sealing collar 13 is sealed and connected to the pressure relief hole. The gravity air release valve assembly is arranged in the sleeve of the sealing collar 13. The gravity air release valve assembly includes a valve body 141 and a counterweight 142 connected together. The gravity air release valve assembly uses a counterweight to achieve different pressure adjustments, avoiding the elastic component commonly used in the air release valve assembly of the prior art to control the opening and closing pressure of the air valve, and has a long service life and a low manufacturing price. To meet the needs of different users, it is only necessary to replace the counterweights of different weights.

[0027] A steam channel is provided on the valve body 141, and the valve body 141 can move up and down on the sealing ring 13. The valve body 141 moves upward to connect the upper space and the lower space of the cover body 11 through the steam channel; when the pressure in the pot continues to increase, the valve body will move upward, and when the valve body moves upward to the limit, the steam channel is opened, thereby releasing steam to achieve pressure relief.

[0028] Although the micro-pressure cooker does not reach the 80KPa of a high-pressure cooker, it also has a certain cooking pressure. In order to prevent the steam from blowing the lid open or the soup from overflowing, a lid ear 13 is provided on the lid body 11, and a buckle 131 is provided on the lid ear 13. The buckle 131 is connected to the pot body to lock the pot lid tightly on the pot body. In some embodiments, the micro-pressure cooker lid is arranged on the pot body 2, and a lock is provided on the pot body 2, and the lock is connected to the buckle 131.

[0029] Relying on the machining accuracy of the pot body and the pot cover, it is difficult to ensure that the sealing between the pot body and the pot cover can reach 12KPa. For this reason, in some embodiments, a sealing ring 15 is provided on the micro-pressure pot cover, and the micro-pressure pot cover is connected to the pot body through the sealing ring.

[0030] In order to facilitate manufacturers to use the same valve body to adapt to different specifications and models of micro-pressure cookers, the valve body 141 and the counterweight 142 are detachably connected. With this arrangement, users can also achieve different pressures of the micro-pressure cooker by replacing counterweights of different weights.

[0031] In some embodiments, the steam channel includes an air inlet 1411 and an air outlet 1412. The air inlet 1411 is provided at the lower side of the valve body 141, and the air inlet 1411 is communicated with the lower space of the cover body 11. The upper side of the valve body 141 is provided with an air outlet 1412. Such a structure is simple and low in cost, because the air valve structure of the prior art.

[0032] In order to facilitate the replacement of the gravity deflation valve, the sealing collar 13 is made of soft material, and the valve body 141 is detachably connected to the sealing collar 13. With this arrangement, the user can directly replace the gravity deflation valve without replacing the counterweight to achieve different working pressures of the micro-pressure cooker, giving the user more choices.

[0033] In some embodiments, the lock includes an elastic buckle 21 connected to the pot body 2, and a buckle hole 211 is provided on the elastic buckle 21. The buckle portion 131 can be connected or separated from the buckle hole 211 under the elastic deformation of the elastic buckle 21. The separation and connection of the pot body and the pot cover are achieved through the elastic deformation of the material. Such a structure is simple, safe and reliable, and has a low manufacturing cost.

[0034] For easy operation, the elastic buckle piece extends upward as a whole, and the elastic buckle piece tilts outward as a whole. A pressing operation part 211 is provided on the elastic buckle piece 21, and the pressing operation part 211 is located outside the buckle hole 211. The buckle part 131 and the buckle hole 211 are both extended horizontally as a whole. When the pressing operation part is pressed downward, the buckle hole 211 will have an outward displacement, so that the pot cover is unlocked from the pot body.

[0035] In some embodiments, a pot ear 3 is provided on the pot body 2, and an elastic buckle 21 is provided on the pot ear 3. The elastic buckle 21 is connected to the pot body 2 through the pot ear 3. This has a high degree of integration and can also save costs in manufacturing.

[0036] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
