It is clean and hygienic to use, has no radiation, saves time and effort, and is one of the indispensable tools for modern housework.

[0003] A Chinese patent discloses a temperature measuring device for an electric hot pot and an electric hot pot (authorization announcement number CN209915681U). According to the patented technology, when the temperature sensing element is pressed into the through hole, the first shoulder on the temperature sensing element effectively increases the distance between the temperature sensing element and the inner wall of the through hole, reduces the heat conduction from the heating plate to the temperature sensing element, improves the temperature sensing accuracy of the temperature sensing element, and prevents foreign matter from entering the bottom of the heating plate.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the existing electric hot pot is in use, water will splash out of the electric hot pot when it boils, causing water to accumulate on the tabletop, which can easily cause the electric heating plate at the bottom of the electric hot pot to get damp and become damaged. At the same time, the flat tabletop is not conducive to the dissipation of heat generated when the electric hot pot is running, which can easily cause the electronic components inside the electric hot pot to overheat and reduce the service life of the electric hot pot.

At the same time, the wind force generated by the rotation of the fan blade 8 driven by the driving motor 7 arranged at the bottom of the bracket 4 is used to dissipate wind heat on the bottom of the electric hot pot, so as to prevent the electric hot pot from spontaneous combustion due to overload operation.

When the staff places the electric hot pot on the top of the bracket 4, the threaded rod 10 is screwed inward, so that the threaded rod 10 pushes the first extension block 11 and the clamping plate 12 to clamp the electric hot pot, fix the position of the electric hot pot, and prevent the electric hot pot from being tipped over by external force.

[0025] Reference Figure 3As shown, in this embodiment: the end of the extension plate 9 away from the shell 1 is fixedly connected with a handle 13. By setting the handle 13 on one side of the extension plate 9, the staff can hold the handle 13 and move the device, thereby improving the portability and practicality of the device.

The staff removes the round cover 16 from the drain pipe 14 The surface of the casing 1 is twisted out to open the opening of the drain pipe 14, so that the liquid collected in the casing 1 can flow out through the drain pipe 14, thereby facilitating the staff to clean the residual liquid in the casing 1. The staff places the electric hot pot connecting line in the specified position, connects the second extension block 17 with the rotating pin 18, and then rotates the limit ring 19 to the specified position, and then pushes the limit rod 23 backward to compress the spring 22 to store force, and then releases the limit rod 23 to release the force generated by the spring 22, so that the spring 22 pushes the limit rod 23 forward to insert into the limit ring 19, thereby restraining the power cord of the electric hot pot to prevent the power cord from curling and winding to cause safety hazards. When the limit rod 23 moves under the thrust of the spring 22, the elastic force of the spring 22 is restrained by the sliding connection between the T-shaped rod 25 and the slide groove 24, thereby restraining the position of the limit rod 23 to the inner wall of the circular hole 21 to prevent the limit rod 23 from detaching from the inner wall of the circular hole 21.
