Technical Field
[0001] The utility model relates to the technical field of glass pot covers, in particular to an explosion-proof tempered glass pot cover. Background Art
[0002] Glass pot lid is a common auxiliary tool for cooking. Its main material is heat-resistant glass. The design of this pot lid enables it to clearly display the state of the food in the pot, allowing users to easily observe the changes in the food during the cooking process, so as to better grasp the cooking temperature and time. The advantages of using a glass pot lid are its high transparency, good heat resistance, not easy to deform, and not easy to react chemically with food like a metal pot lid.
[0003] The pressure relief valve automatically opens when the pressure inside the pot exceeds the safe range to release excess pressure to prevent the pot from being dangerous due to excessive pressure. However, the design of some pressure relief valves has not fully achieved the expected effect and cannot achieve stable pressure relief of the pressure inside the pot. At the same time, when the pressure relief valve starts working, it cannot effectively send a warning signal to the user, which means that the user cannot notice the working status of the pressure relief valve in time, and cannot realize that the pressure in the pot has reached the level that needs to be released, thereby increasing the risk during use. Therefore, in view of the above shortcomings, an explosion-proof tempered glass pot lid is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1 - Figure 3The utility model provides an embodiment: an explosion-proof tempered glass pot cover, comprising a cover body 1, the cover body 1 is used to cover the pot body to seal the pot environment, an air outlet pipe 2 is connected to the left side of the top of the cover body 1, and a plurality of air outlet holes 3 are opened inside the air outlet pipe 2. When the pressure in the pot increases, the gas can escape through these holes to reduce the pressure in the pot. The air outlet pipe 2 is slidably connected to the inside of the air outlet pipe 2, and the bottom of the sliding block 4 is connected to a sealing ring 5. The outside of the sealing ring 5 is slidably connected to the inside of the air outlet pipe 2. The sealing ring 5 ensures that the pot is sealed when the pressure is not released.
[0033] A sliding rod 6 is connected to the top of the sliding block 4, and a spring 7 is sleeved on the outside of the sliding rod 6. One end of the spring 7 is connected to the bottom of the top cover 8, and the other end of the spring 7 is connected to the top of the sliding block 4. The spring 7 plays a buffering and resetting role, and helps the sliding block 4 to reset after the pressure is released. The top of the air outlet pipe 2 is connected to the top cover 8, and the outside of the sliding rod 6 is slidably connected to the inside of the top cover 8. The top of the top cover 8 is connected to a lower paddle 9, and the outside of the sliding rod 6 is slidably connected to the inside of the lower paddle 9. The top side of the outside of the sliding rod 6 is connected to an upper paddle 10, and the bottom of the upper paddle 10 contacts the top of the lower paddle 9. The two paddles interact with each other to produce a sound when the sliding rod 6 moves to warn the user that the pressure in the pot is being released. A limiting plate 11 is connected to the top of the sliding rod 6.
[0034] Reference Figure 3 - Figure 5 The inside of the cover body 1 is provided with an explosion-proof component for preventing explosion, and the explosion-proof component includes a glass top layer 12, the outside of the glass top layer 12 is connected to the inside of the cover body 1, and the bottom of the glass top layer 12 is connected with an elastic adhesive layer 13. The material of the elastic adhesive layer 13 is polyvinyl butyral, which is a polymer plastic material with good transparency, adhesion and toughness. The bottom of the elastic adhesive layer 13 is connected with a glass bottom layer 14. The material of the glass top layer 12 and the glass bottom layer 14 is tempered glass, which is a safety glass that has been specially processed to enhance its strength and heat resistance. The glass top layer 12 and the glass bottom layer 14 are bonded by the elastic adhesive layer 13, and the elastic adhesive layer 13 can stick to the fragments when the glass breaks to avoid splashing and injuring people.
[0035] The inside of the cover body 1 is connected with a plurality of reinforcing ribs 15, which are made of aluminum alloy. The function of the reinforcing ribs 15 is to increase the overall structural strength of the pot cover, provide better impact resistance and pressure bearing capacity, and ensure that the pot cover can remain intact under long-term use or extreme conditions, and will not be easily deformed or damaged. The bottom of the cover body 1 is connected with an anti-overflow retaining ring 16, and the inside of the anti-overflow retaining ring 16 is connected with a sealing ring 17. The anti-overflow retaining ring 16 and the sealing ring 17 are used to provide additional sealing performance to prevent liquid from overflowing. The inside of the air outlet pipe 2 is connected with a top block 18, and the outside of the top block 18 is connected to the inside of the glass bottom layer 14. The top of the top block 18 is connected with a handle 19, and the handle 19 is convenient for the user to operate the pot cover.
[0036] When the pot cover is placed on the pot body for cooking, when the internal pressure is relatively large, the sliding block 4 will be lifted up, and then the spring 7 will be compressed. At this time, the height of the sliding block 4 will be higher than the air outlet 3, and the air outlet 3 will be connected to the pot, and stable pressure relief can be achieved. When the pressure relief is completed, the spring 7 will rebound, and it will be reset as the upper paddle 10 is displaced. At this time, the upper paddle 10 can be reset and then hit the top of the lower paddle 9. A sound can be made by the collision between the lower paddle 9 and the upper paddle 10, so as to warn the user to pay attention. At the same time, with the help of the glass top layer 12, the glass bottom layer 14 and the elastic rubber layer 13, when the pot cover is broken, the glass top layer 12 and the glass bottom layer 14 can be adhered by the elastic rubber layer 13, and the splashing of glass fragments can be prevented to cause secondary damage. At the same time, the explosion-proof performance of the pot cover can be greatly enhanced with the help of the reinforcing ribs 15.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
