In this regard, this case provides a heating device of a small appliance with a self-sealing function to improve it.

[0003] According to the description of the heating device of a small appliance with a self-closing function disclosed on the patent website (authorization announcement number: CN216221164U), "it includes a barrel body, a barrel cover is placed on the top of the barrel body, a handle is fixedly installed on the outside of the barrel body, and a fixing column is evenly fixedly installed on the inner wall of the bottom end of the barrel body. A placement groove is opened on the outside of the fixing column, and a sliding block is slidably installed on the inside of the placement groove. A placement plate is fixedly installed on one end of the sliding block. Through the provision of a suspended heating mechanism, the position of the placement frame can be adjusted according to different usage requirements, thereby improving the heating adjustability of the heating device of the small appliance during use.

[0029] The utility model provides the following technical solutions:

[0030] Example 1

[0031] See also Figure 1-4 A heating device for a small electrical appliance with a self-sealing function comprises a base 1, a heating mechanism 2 is fixedly connected to the top of the base 1, a barrel cover 3 is rotatably connected to the left side of the top of the heating mechanism 2, a sealing ring 4 is fixedly connected to the bottom of the barrel cover 3, and a sealing mechanism 5 is fixedly connected to the surface of the barrel cover 3;

[0032] The heating mechanism 2 includes a heating component 21 and a fixing component 22. The heating component 21 is fixedly connected to the top of the base 1, and the fixing component 22 is fixedly connected to the inside of the heating component 21.

[0033] The heating assembly 21 includes an outer barrel 211, which is fixedly connected to the top of the base 1. The inner barrel 212 is threadedly connected to the inner barrel 211.

[0036] Furthermore: when heating an item, first pull the handle 224 to pull the entire fixing assembly 22 out of the inner barrel 212, push the fixing plate 226 upward, and move vertically upward along the vertical rod 225 under the restriction of the vertical rod 225 to compress the spring 227, then place the item on the top of the circular plate 221, loosen the fixing plate 226, the spring 227 releases the elastic force, pushes the fixing plate 226 to fix the item, and then pull the entire fixing assembly 22 back into the inner barrel 212. When putting it back, make the bayonet 222 correspond to the slide rail 213 one by one to limit the position of the entire fixing assembly 22 to prevent the fixing assembly 22 from rotating inside the inner barrel 212 during heating. When repairing the heating strip 214, rotate the top of the slide rail 213 to separate the outer barrel 211 together with the base 1, so as to facilitate the replacement and repair of the heating strip 214.

[0037] Example 2

[0038] See also Figure 5-7 , and on the basis of Example 1, it is further obtained that the sealing mechanism 5 includes a closing component 51 and a pressure relief component 52, the closing component 51 is clamped on the right side of the barrel cover 3, and the pressure relief component 52 is fixedly connected to the top of the barrel cover 3;

[0039] The closing assembly 51 includes a rotating base 511, which is fixedly connected to the top right side of the inner barrel 212. An L-shaped clamping plate 512 is rotatably connected to the right side of the rotating base 511. A rectangular hole 513 is formed in the middle of the L-shaped clamping plate 512. A rotating rod 514 is rotatably connected to the left side of the rotating base 511. The top of the rotating rod 514 has a threaded groove 515, and a hexagonal nut 516 is threadedly connected to the surface of the threaded groove 515.

[0040] The bottom of the L-shaped clamping plate 512 is attached to the top of the barrel cover 3, the threaded groove 515 is arranged inside the rectangular hole 513, the bottom of the hexagonal nut 516 is attached to the top of the L-shaped clamping plate 512, and the top of the rotating rod 514 is provided with a limiting piece;

[0041] The pressure relief assembly 52 comprises an exhaust pipe 521 fixedly connected to the top middle part of the barrel cover 3, the exhaust pipe 521 is fixedly connected with a connecting plate 522 inside, the top of the connecting plate 522 is fixedly connected with an extension rod 523, the top end of the extension rod 523 is fixedly connected with an exhaust seat 524, the surface of the exhaust seat 524 is equidistantly provided with exhaust holes 525, the top inside of the exhaust seat 524 is fixedly connected with a tension spring 526, and the bottom end of the tension spring 526 is fixedly connected to the top of the connecting plate 522.

[0042] Further, when the barrel cover 3 needs to be opened, the hexagonal nut 516 is first rotated so that the hexagonal nut 516 rises along the threaded groove 515, the fixation of the L-shaped clamping plate 512 is ended, then the rotating rod 514 and the L-shaped clamping plate 512 are sequentially rotated clockwise, and the fixation of the barrel cover 3 is ended; when closing, the L-shaped clamping plate 512 and the rotating rod 514 are sequentially rotated counterclockwise to the original position, then the hexagonal nut 516 is reversely rotated, the bottom of the hexagonal nut 516 is in contact with the top of the L-shaped clamping plate 512, and the device can be sealed again.

[0043] The fixing plate 226 is pushed upwards and the spring 227 is compressed. Then the article is placed on the top of the circular plate 221, the fixing plate 226 is loosened, the spring 227 releases the elastic force, and the fixing plate 226 is pushed to fix the article. Then the whole fixing assembly 22 is pulled back into the inner barrel 212. When putting it back, the bayonet 222 corresponds to the slide rail 213 one by one, which limits the position of the whole fixing assembly 22 to prevent the fixing assembly 22 from being fixed during heating. After rotating inside the inner barrel 212 and putting back the fixing assembly 22, add heating liquid to the inner barrel 212, close the barrel cover 3, rotate the L-shaped clamping plate 512 and the rotating rod 514 counterclockwise to return to their original positions, and then reversely rotate the hexagonal nut 516 so that the bottom of the hexagonal nut 516 contacts the top of the L-shaped clamping plate 512 to complete the fixation of the barrel cover 3. The sealing ring 4 provided at the bottom of the barrel cover 3 can further ensure the sealing of the device. During heating, when the internal pressure of the inner barrel 212 reaches a certain level, the air pressure pushes the exhaust seat 524 upward through the exhaust pipe 521, causing the exhaust seat 524 to move upward along the exhaust pipe 521, causing the exhaust hole 525 to leak out and exhaust. After the air pressure is discharged, the exhaust seat 524 is driven back to its original position under the tension of the tension spring 526, so that the device returns to a sealed state. After the heating is completed, open the barrel cover 3 and pull the handle 224 to take out the fixing assembly 22 together with the heated item.

[0044] When the heating strip 214 is to be repaired, the outer barrel 211 and the base 1 can be separated by rotating the top of the slide rail 213 , so that the heating strip 214 can be replaced and repaired.
