When the pressure cooker is used, the user generally moves the pressure cooker by holding the handle body 21. Therefore, the handle body 21 is generally made of plastic. The butt joint surface of the handle body 21 of the utility model is generally spaced apart from the side wall of the pot 10, so that the handle body 21 is not directly in contact with the pot 10. In this way, the heat from the metal part of the pot 10 can be isolated while improving the user's holding experience. In addition, the space between the handle body 21 and the pot 10 can also be reserved for the welding connection between the pot 10, improving the convenience of the production process.

[0033] The handle component 20 in the embodiment includes the welding support 22, which is connected to the handle body 21 made of plastic and the pot 10 made of metal. The welding support 22 is generally made of metal, which can be connected to the pot 10 by welding to improve the reliability of the connection. On the other hand, the structural strength of the welding support 22 can also improve the stability and strength of the connection between the handle body 21 and the pot 10.
