Detailed Embodiments

[0030] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. Based on the embodiments in the implementation manners, it is intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0031] As used in this specification, the phrase "an embodiment" or "an example" or "an instance" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment of the present patent disclosure. The appearances of the phrase "in an embodiment" in various positions in the specification do not necessarily refer to the same embodiment.

[0032] The present utility model provides a pot body, as Figures 1 to 3 shown, which includes a pot body main body 11, a handle 12, and a pot rim 13. The pot rim 13 is disposed around the opening of the pot body main body 11, the pot rim 13 is connected to the opening of the pot body main body 11, and the pot rim 13 extends in a direction away from the pot body main body 11. The handle 12 contacts one side of the pot rim 13 facing the bottom of the pot body main body 11.

[0033] The handle 12 is formed with an installation through hole, and the opening direction of the installation through hole is consistent with the thickness direction of the pot rim 13.

[0034] The pot body further includes a conductive fixing member, which includes a welding portion 141, a fixing member main body 142, and an electrical connection portion 143. The fixing member main body 142 is connected between the welding portion 141 and the electrical connection portion 143. The welding portion 141 and the fixing member main body 142 are both disposed in the installation through hole. The welding portion 141 is attached to the pot rim 13, and the electrical connection portion 143 is fixed in the installation through hole.

[0035] During production, the conductive fixing member is placed in the installation hole of the handle 12, the handle 12 is aligned with the pot rim 13, and the welding portion 141 is aligned with the welding place of the pot rim 13. The resistance spot welder is pressed against the electrical connection portion 143, and the resistance heat generated by the current flowing through the contact surface and the adjacent area between the welding portion 141 and the pot rim 13 is used to heat it to a molten or plastic state, so that the welding portion 141 and the pot rim 13 are welded together.

[0036] In the traditional method, it is necessary to weld threaded pot ears on the pot body, and then fix the handle 12 to the pot body with fasteners such as screws. Compared with the traditional method, the utility model sets a conductive fixing, combines it with the resistance spot welding process, and energizes the electrical connection part 143 at the opening of the installation through hole, so as to weld the conductive fixing to the pot edge 13, thereby realizing the connection between the handle 12 and the pot body 11, eliminating the processing and installation steps of the pot ears, greatly simplifying the production process, and improving production efficiency. In addition, since the number of processing steps and required accessories (such as screws, nuts, pot ears, etc.) is reduced, the production cost is reduced. In addition, compared with the screw fixing method, the welding connection between the conductive fixing and the pot edge 13 is more secure, avoiding the problem of connection failure caused by loose screws during long-term use, and improving the durability and service life of the cookware.

[0037] In the present invention, there is no special limitation on the material of the handle 12. To ensure that the user will not be injured due to overheating of the pot during cooking, the handle 12 is made of a heat-insulating material, such as bakelite.

[0038] Alternatively, if Figure 2 and Figure 3 As shown, the mounting through hole includes a connecting groove 12a and a clamping groove 12b. The connecting groove 12a is connected to the clamping groove 12b. The clamping groove 12b is located on the side of the connecting groove 12a away from the pot edge 13. The diameter of the connecting groove 12a is smaller than the diameter of the clamping groove 12b.

[0039] The fixing member body 142 is disposed in the connection groove 12 a , and the electrical connection portion 143 is disposed in the clamping groove 12 b , and the diameter of the electrical connection portion 143 is greater than the diameter of the connection groove 12 a .

[0040] By processing the diameter of the slot 12b to be larger than the diameter of the connecting slot 12a, and the diameter of the electrical connection part 143 is larger than the diameter of the connecting slot 12a, after the welding part 141 is welded to the pot edge 13, the electrical connection part 143 can be snapped into the slot 12b to prevent the handle 12 from detaching from the pot edge 13 and the pot body 11, thereby achieving relative fixation of the handle 12, the pot edge 13 and the pot body 11.

[0041] Alternatively, if Figure 4 and Figure 5 As shown, the pot body further includes an elastic member, which is connected between the electrical connection portion 143 and the bottom wall of the slot 12b.

[0042] Generally, when the electrical connection part 143 is snapped into the card slot 12b, the welding part 141 just fits against the pot edge 13 for welding, which requires a high dimensional accuracy of the conductive fixing part. By arranging an elastic part between the electrical connection part 143 and the bottom wall of the card slot 12b, the total length of the electrical connection part 143 and the fixing part body 142 is slightly greater than the depth of the connection groove 12a. In this way, when spot welding, a certain pressure is applied to the electrical connection part 143, and the elastic part is compressed, ensuring that the welding part 141 fits against the pot edge 13 during welding, thus ensuring successful welding and reducing the requirement for the dimensional accuracy of the conductive fixing part.

[0043] It can be understood that in order to avoid the influence on the spot welding of the welding part 141 due to the existence of other connected conductive components when the electrical connection part 143 is energized, in the present utility model, the elastic part is made of a non-conductive material. In an optional embodiment, the elastic part includes a silicone rubber ring 15. The silicone rubber ring 15 is sleeved on the fixing part body 142, and the opposite sides of the silicone rubber ring 15 are respectively in contact with the electrical connection part 143 and the card slot 12b.

[0044] Optionally, as Figure 2 and Figure 3 shown, one side of the handle 12 facing the side wall of the pot body 11 fits against the side wall of the pot body 11.

[0045] One side of the handle 12 facing the pot edge 13 fits against the pot edge 13, and one side of the handle 12 facing the side wall of the pot body 11 fits against the side wall of the pot body 11. In this way, during use, stress can be dispersed, avoiding stress concentration at the welding joint between the welding part 141 and the pot edge 13, preventing the connection between the handle 12 and the pot edge 13 from failing, and reducing product damage.

[0046] In an optional embodiment, as Figure 2 and Figure 3 shown, the pot body 11 includes a pot mouth part 113, a transition part 112, and a pot body part 111. The transition part 112 is connected between the pot mouth part 113 and the pot body part 111, and the pot mouth part 113 is connected to the pot edge 13.

[0047] The diameter of the transition part 112 is smaller than that of the pot mouth part 113. One side of the handle 12 facing the pot mouth part 113 fits against the outer wall of the pot mouth part 113, and one side of the handle 12 facing the transition part 112 fits against the outer wall of the transition part 112.

[0048] By processing the diameter of the transition part 112 to be smaller than that of the pot mouth part 113 to form a turning angle, when holding the handle 12, part of the pressure is dispersed at the part where the handle 12 fits against the transition part 112, further reducing the influence of stress concentration on the connection stability between the handle 12 and the pot edge 13.

[0049] Optionally, as Figure 1and Figure 6 As shown in Figure 6 , the handle 12 includes a grip portion 122 and two mounting portions 121. The grip portion 122 is connected between the two mounting portions 121. The mounting portions 121 are in contact with one side of the pot edge 13 facing the bottom of the pot body 11, and mounting through holes are formed in the mounting portions 121.

[0050] By providing two mounting portions 121, the connection between the handle 12 and the pot body is not limited to a single point or line, but forms a multi-point support structure, which can effectively disperse stress, avoid stress concentration, and extend the service life of the handle 12 and the pot body. Moreover, the contact area between the handle 12 and the pot body is increased, thereby improving the connection strength and stability.

[0051] In an alternative embodiment, as Figure 1 and Figure 6 shown in Figure 6 , a grip space is formed by enclosing the grip portion 122, the mounting portion 121 and the pot edge 13.

[0052] Through the grip space formed by enclosing the grip portion 122, the fixing member main body 142 and the pot edge 13, the user's palm can naturally fit therein, reducing the hand fatigue. Moreover, the enclosed grip space provides a stable support point for the palm, and the cooking utensil is not easy to slip out of the hand, improving the safety of use. Combining the heat insulation material and the design of the enclosed grip space can prevent the high temperature of the pot body from being conducted to the hand, further improving the safety of use.

[0053] In order to improve the grip stability, in some other embodiments, anti-slip patterns are provided on the surface of the grip portion 122, thereby reducing the risk of slipping caused by sweating or wetness of the hand.

[0054] Optionally, the pot body includes two handles 12, and the two handles 12 are respectively arranged at two ends of the pot edge 13 along the radial direction.

[0055] Compared with a single handle 12, the two handles 12 provide more support points, thereby providing a more stable support for the pot body 11. Moreover, the design of the two handles 12 makes the force on the handles 12 relatively uniform, avoiding the connection failure between the handle 12 and the pot edge 13 caused by excessive force at a single point.

[0056] A pressure cooker includes a pot lid. The pressure cooker further includes the pot body according to any one of the above, and the pot lid is arranged on the pot body.

[0057] By assembling the pot body in the foregoing embodiments, the connection stability between the handle 12 and the pot body 11 is increased, the service life of the pressure cooker is improved, and the materials required for processing and production are reduced, thereby reducing the production cost.

[0058] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that the present utility model includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present utility model will be included in the scope of the claims.
