[0032] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of 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.
[0033] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: an enhanced pot lid with pressure relief function, including a top cover 1 and a pot body 2. The left sides of the top cover 1 and the pot body 2 are both connected with a handle assembly for holding. Here, the top cover 1 and the pot body 2 provide stable support for the handle assembly. The handle assembly includes an upper grip 3 and a lower grip 4. The right sides of the upper grip 3 and the lower grip 4 are respectively connected to the left sides of the top cover 1 and the pot body 2. Here, the upper grip 3 and the lower grip 4 can be combined to ensure the locking of the top cover 1 and the pot body 2. The right top end of the pot body 2 is connected with a side grip 5. The inner wall of the top end of the top cover 1 is connected with a top column 6. Here, the top cover 1 plays a role of supporting and fixing the top column 6.
[0034] Referring to Figure 3 - Figure 4 , two limit blocks 7 are slidably connected to the inner wall of the top column 6. A inner column 8 is connected to the adjacent sides of the two limit blocks 7. The limit blocks 7 here can ensure that the inner column 8 moves in a straight line when sliding upward and prevent deviation. The top end of the inner column 8 is connected to a top block 9. The bottom end of the top block 9 is in contact with the inner wall of the top column 6. Under normal conditions, that is, when the pressure is within the normal range, the top block 9 here is in close contact with the inner wall of the top column 6. Two air outlet valves 10 are connected to the right side of the top end of the top cover 1. The air outlet valves 10 here are used to cooperate with the top column 6 to relieve pressure when the pressure inside the pot body 2 reaches the peak value. A pressure equalizing component for controlling pressure is slidably connected to the inner wall of the top cover 1. The pressure equalizing component includes an orifice plate 11. The outside of the orifice plate 11 is slidably connected to the inner wall of the top cover 1. Here, the top cover 1 provides stable support for the orifice plate 11. The outside of the top column 6 is slidably connected to the inner wall of the orifice plate 11. The bottom end of the inner column 8 is connected to the inner wall of the orifice plate 11.
[0035] Referring to Figure 5 - Figure 6 , a sliding ring 12 is connected to the outside of the orifice plate 11. The sliding ring 12 here can ensure that the orifice plate 11 slides in a straight line and plays a role of limiting at the same time. The outside of the sliding ring 12 is slidably connected to the inner wall of the top cover 1. A plurality of holes 13 are formed in the inside of the orifice plate 11. When cooking food by simmering, water vapor will flow inside the plurality of holes 13 here, so that the pressure inside the entire pot body 2 is in an equilibrium state. A rubber pad 14 is connected to the inner wall of the bottom end of the top cover 1. Here, the top cover 1 provides stable support for the rubber pad 14. A sealing component for ensuring gas tightness is connected to the top end inner wall of the pot body 2.
[0036] The sealing component includes an inner box 15. The outside of the inner box 15 is connected to the top end inner wall of the pot body 2. Here, the pot body 2 provides stable support for the inner box 15. A groove 16 is formed in the inside of the inner box 15. A rubber ring 17 is slidably connected to the inner wall of the groove 16. The groove 16 here provides a sliding space for the rubber ring 17. The outside top end of the rubber ring 17 is slidably connected to the inner wall of the rubber pad 14. A limit ring 18 is connected to the bottom end of the rubber ring 17. The limit ring 18 here is used to prevent the rubber ring 17 from detaching from the inner wall of the groove 16. At the same time, when the top cover 1 and the pot body 2 are in a locked state here, the rubber ring 17 will be tightly engaged with the inner wall of the bottom end of the rubber pad 14, ensuring the overall airtightness.
[0037] The outer part of the limiting ring 18 is slidably connected to the inner wall of the groove 16. A plurality of springs 19 are arranged inside the groove 16. The springs 19 here are used to provide a force, so that the rubber ring 17 and the rubber pad 14 are squeezed more tightly, ensuring the sealing effect. One end of the spring 19 is connected to one side of the limiting ring 18, and the other end of the spring 19 is connected to one side of the inner wall of the groove 16. The limiting ring 18 and the groove 16 here provide stable support for the spring 19, making it stable when stretching and contracting.
[0038] During use: First, place the food to be simmered into the interior of the pot body 2, and then cover the top cover 1 on the top of the pot body 2. At the same time, use the upper handle 3 and the lower handle 4 to lock it, so as to fix the top cover 1 and the pot body 2 together. After starting to simmer the food, when the pressure inside the pot body 2 reaches the peak value, at this time, the orifice plate 11 will be pushed by the pressure. The sliding ring 12 here plays a role of limiting, ensuring that the orifice plate 11 moves in a straight line when sliding upward and will not deviate. When the orifice plate 11 slides upward here, it will drive the inner column 8 to slide upward together, so that the top block 9 is separated from the inner wall of the top column 6. At this time, in cooperation with the air outlet valve 10, the water vapor will flow out to the outside from the gap between the top column 6 and the top block 9, achieving the purpose of pressure relief. At the same time, the plurality of holes 13 formed on the surface of the orifice plate 11 here can make the water vapor inside the pot body 2 flow evenly, ensuring the uniformity of the pressure inside the pot body 2.
[0039] The sealing performance between the pot body 2 and the top cover 1 is very important when simmering food. Therefore, when the top cover 1 is covered on the top of the pot body 2, the rubber ring 17 here will slide to the inner wall of the rubber pad 14 and be squeezed at the same time. At this time, the rubber ring 17 will transmit the squeezing force downward, so that the limiting ring 18 cooperates with the groove 16 to squeeze the spring 19, generating a force, so that the rubber ring 17 and the inner wall of the rubber pad 14 are squeezed more tightly, thereby improving the sealing performance.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
