[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] like Figure 1 and Figure 2 As shown, the cooking utensil of this embodiment includes a pot body, a pot cover and a pressure limiting valve assembly 20. The pot body is used to hold the food to be cooked. The pot cover is arranged on the pot body, and an exhaust passage 10 is arranged in the pot cover. The pressure limiting valve assembly 20 includes a pressure limiting valve body 21 and a counterweight 22, and the pressure limiting valve body 21 is used to block or open the exhaust passage 10. The gravity of the counterweight 22 is transmitted to the pressure limiting valve body 21, and acts on the exhaust passage 10 together with the gravity of the pressure limiting valve body 21. The counterweight 22 includes a first shell 221, and the first shell 221 includes a plurality of metal shells 30 that are stretched and overlapped.

[0024] By applying the technical solution of this embodiment, the first shell 221 of the counterweight 22 includes a plurality of metal shells 30 formed by stretching and stacked. The above structure allows the first shell 221 to be decomposed into a plurality of metal shells 30 with relatively thin thickness, so that the metal shells 30 can be manufactured by a stamping process, greatly reducing the processing cost. At the same time, the first shell 221 can also be guaranteed to have a certain weight. Therefore, the technical solution of this embodiment solves the problem of high processing and manufacturing cost of the counterweight of the electric pressure cooker in the prior art.

[0025] Preferably, in this embodiment, the plurality of metal shells 30 are connected together by welding. Of course, the plurality of metal shells 30 can also be connected together by bonding or other methods.

[0026] Preferably, in this embodiment, the metal shell 30 is formed by a stamping process. Specifically, since the metal shell 30 is thin, it can be formed by a stamping process. The stamping process has the characteristics of low cost and suitable for mass production. Therefore, the solution of this embodiment can greatly reduce the production cost of the cooking utensil.

[0027] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the plurality of metal shells 30 include an inner shell 31 and an outer shell 32, the outer shell 32 is sleeved outside the inner shell 31, and the outer shell 32 and the inner shell 31 together form the first shell 221. Specifically, in this embodiment, the metal shell 30 has two layers, namely, the inner shell 31 and the outer shell 32 mentioned above. Of course, according to different weight requirements in the first shell 221, the metal shell 30 can also be set to have more layers. The inner shell 31 and the outer shell 32 are both cylindrical structures with openings facing downward. The upper ends of the inner shell 31 and the outer shell 32 both have a top wall. The outer shell 32 is sleeved outside the inner shell 31, and the two are stacked to form the first shell 221.

[0028] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the first shell 221 is a cylindrical structure with an opening at the lower end, and the counterweight block 22 also includes a second shell 222 connected to the inner side of the first shell 221. The second shell 222 is made of plastic material, and an anti-slip structure 40 is arranged between the second shell 222 and the pressure-limiting valve body 21. Specifically, the above structure has the following advantages: Since the second shell 222 is made of plastic, it is easy to mold the anti-slip structure 40 on the second shell 222, and reduce the processing difficulty. The outer first shell 221 is formed by stacking a plurality of metal shells 30, which ensures that the counterweight block 22 has a certain weight. The above structure makes it easy to process the anti-slip structure 40 on the premise that the counterweight block 22 has a certain weight.

[0029] Preferably, in the technical solution of this embodiment, the first shell 221 and the second shell 222 are connected together by an integral injection molding process. Specifically, after the inner shell 31 and the outer shell 32 are connected together by welding, the inner shell 31 and the outer shell 32 are placed in a mold, and then the second shell 222 is formed on the first shell 221 by an integral injection molding process.

[0030] In the technical solution of the present embodiment, a first magnetic member 50 is arranged on the counterweight 22, and the cooking utensil further comprises a driving mechanism, and the driving mechanism comprises a second magnetic member. The second magnetic member has a first position corresponding to the first magnetic member 50 and a second position displaced from the first magnetic member 50. When the second magnetic member is in the first position, the counterweight 22 is separated from the pressure-limiting valve body 21, and when the second magnetic member is in the second position, the counterweight 22 is supported by the pressure-limiting valve body 21. Specifically, the above structure can control whether the counterweight 22 acts on the pressure-limiting valve body 21. Furthermore, the above driving mechanism may further comprise a swing rod, and the second magnetic member is arranged on the swing rod. The swing rod can be driven to swing by a motor, and the second magnetic member can be moved between the first position and the second position. Of course, skilled technicians can adopt other mechanisms as driving mechanisms according to conventional designs.

[0031] like Figure 2 As shown, in the technical solution of this embodiment, the first magnetic member 50 is sandwiched between the first shell 221 and the second shell 222. Specifically, when the second shell 222 is injection molded, the first shell 221 is placed in the mold, and then the first magnetic member 50 is placed in the first shell 221. After the injection molding is completed, the first magnetic member 50 can be fixed between the first shell 221 and the second shell 222. The above structure enables the first magnetic member 50 to be located inside the counterweight 22, thereby preventing the first magnetic member 50 from falling off and being lost.

[0032] like Figure 2 As shown, in the technical solution of this embodiment, a positioning hole 311 is provided on the top wall of the inner shell 31, and the first magnetic member 50 is disposed in the positioning hole 311. The above structure facilitates the positioning of the first magnetic member 50 during injection molding. Preferably, the positioning hole 311 is located at the center of the top wall of the inner shell 31.

[0033] Preferably, the cooking utensil in this embodiment is an electric pressure cooker, the exhaust passage 10 is an exhaust pipe, and the pressure limiting valve body 21 is sleeved outside the exhaust pipe. Of course, other open flame cookers and electric cookers using pressure limiting valves and counterweights can adopt the above structure.
