Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of heat preservation barrels, and particularly relates to a heat preservation barrel. BACKGROUND

[0002] The heat preservation barrel is a storage device for food or other articles, and is a necessary appliance in many families. Eating hot food is good for the digestion of the stomach and intestines. In life, people need to use the heat preservation barrel to take food due to work and other reasons. In general, the heat preservation barrel is used to keep food warm, so that people can eat hot food at any time and anywhere. At present, most of the heat preservation barrels on the market are closed together by threads, so that the barrel is tightly closed and cannot leak water. When closing the barrel cover, people need to hold the barrel body with one hand and hold the barrel cover with the other hand, and then use a little force to close the barrel cover relative to the barrel body. The same is true for opening the barrel cover. Especially when the barrel cover is closed after hot water is put in the barrel, the water is cooled after a period of time, and a negative pressure is formed in the barrel, so that the barrel cover is more difficult to open. If the barrel cover is opened too quickly or with improper force, not only the food may be spilled, but also the user's hands or other body parts may be scalded due to high temperature. SUMMARY

Through this design, even if the user accidentally touches the bucket cover 2 when not using the heat preservation bucket, it is not likely to accidentally press the driving part 5, thereby effectively preventing the loss of hot air in the heat preservation bucket and ensuring the heat preservation effect.

[0031] Preferably, the rear end of the driving part 5 is provided with a limiting rod 9, and the limiting rod 9 is provided with a limiting block 10, so as to limit the movement of the driving part 5, and the end of the elastic piece 7 is sleeved on the limiting rod 9 and abuts against the limiting block, so as to ensure that the driving part 5 can be effectively limited and controlled during movement. This design not only improves the stability and reliability of the driving part 5, but also ensures that it moves accurately within a certain range.

[0032] Preferably, the upper end of the driving part 5 is provided with a stepped part 11, the stepped part 11 abuts against the periphery of the mounting hole 6, and the bucket cover 2 is concave and has a limiting part 12 below, the limiting part 12 is located at the rear end of the driving part 5 and is spaced apart from the driving part 5 by a gap. When the driving part 5 needs to move backward, it will continue to move until the clamping piece 4 is completely separated from the clamping groove 3. In this process, the rear end of the driving part 5 will abut against the limiting structure, thereby ensuring that the driving part 5 will not exceed the predetermined range during movement, and also ensuring the stability and reliability of the entire device. This design not only improves the service life of the device, but also ensures the safety and accuracy during operation.

[0033] Preferably, the bottom of the bucket cover 2 is provided with a guide groove 13, and the lower end of the clamping piece 4 is provided with a guide part 14, the edge of the guide part 14 abuts against the guide groove 13 and can move in the guide groove 13. The guide part 14 can smoothly move in the guide groove 13, thereby realizing flexible connection between the clamping piece 4 and the bucket cover 2. This design not only improves the stability of the connection, but also ensures the convenience of operation. The accurate design of the guide groove 13 enables the guide part 14 to easily slide therein without excessive friction or obstruction. In this way, the connection between the clamping piece 4 and the bucket cover 2 becomes more reliable, reducing the possibility of loosening or falling off.

[0034] Preferably, the lower end of the bucket cover 2 is provided with a mounting groove 16, and a sealing element 17 is arranged in the mounting groove 16, the sealing element 17 is arranged around the periphery of the bucket cover 2, and an abutting inclined surface 15 is arranged at the bucket opening, the abutting inclined surface 15 is inclined inward from top to bottom, and the sealing element 17 abuts against the abutting inclined surface 15, the sealing element 17 is designed in a ring shape, which is perfectly matched with the periphery of the bucket cover 2, thereby forming a structure with excellent sealing effect. When the bucket cover 2 is correctly installed on the bucket opening, the sealing element 17 will be in close contact with the abutting inclined surface 15 at the bucket opening, thereby further enhancing the sealing effect and ensuring that the substances in the bucket will not leak.

[0035] Preferably, the bucket cover 2 is provided with an exhaust hole 18, and a plugging element 19 is arranged in the exhaust hole 18, and a sealing part 20 is arranged at the lower end of the plugging element 19, and the sealing part 20 blocks the lower surface of the exhaust hole 18, and in use, the sealing part 20 is driven to move downward by the plugging element 18, thereby opening the exhaust hole 18. In order to ensure safety, some preventive measures need to be taken to prevent the bucket cover 2 from flying off due to the sudden opening of the bucket cover 2 when hot water is contained in the cup. Specifically, when hot water is contained in the cup, the air pressure in the bucket will increase due to the principle of thermal expansion and cold contraction, and if the bucket cover 2 is suddenly opened at this time, the high-speed spraying of hot water and air pressure may cause the bucket cover 2 to lose control. In order to avoid this situation, the utility model is provided with an exhaust hole 18 on the bucket cover 2, and when the bucket cover 2 is opened, the plugging element 19 is first pressed, and the plugging element 19 is moved downward, thereby driving the sealing part 20 to move downward, the exhaust hole 18 is opened, and the air pressure is reduced, and then the bucket cover 2 is slowly opened, thereby ensuring the safety of the operation.

[0036] The above embodiments are only preferred embodiments of the utility model, and do not limit the protection scope of the utility model, therefore: equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
