[0027] See also Figure 1-Figure 4 The utility model provides an outer pot structure, including an outer pot 1 and a pressure switch 2. The outer pot 1 has an outer bottom wall 11. The pressure switch 2 has a fixed end 21 and a deformed end 22. The outer bottom wall 11 is provided with a fixed platform 12. The fixed end 21 is fixedly mounted on the fixed platform 12. The deformed end 22 abuts against the outer bottom wall 11 of the outer pot 1. Specifically, the pressure switch 2 is a displacement sensor, which is directly fixed to the outer bottom wall 11 of the outer pot 1 through the fixed end 21 thereon. The assembly difficulty is low, the assembly efficiency is improved, the stability of the pressure switch installed on the bottom wall is higher, the workload of pressure debugging can be effectively reduced, and the transportation cost and labor cost of the outer pot 1 are greatly reduced.

[0028] Further, the outer pot structure includes bolts, the fixing platform 12 is formed by the outer bottom wall 11 protruding downward, at least one first fixing hole 121 is provided on the fixing platform 12, and a second fixing hole 211 is provided on the fixing end 21, the first fixing hole 121 corresponds to the second fixing hole 211, and the bolt passes through the first fixing hole 121 and the second fixing hole 211 to fix the fixing platform 12 and the fixing end 21. Specifically, the first fixing hole 121 is provided on the fixing end 21 of the displacement sensor, and correspondingly, the first fixing hole 121 is provided on the fixing platform 12, and the fixing end 21 is fixedly installed to the fixing platform 12 by passing the second fixing hole 211 and the first fixing hole 121 with a bolt or a screw, thereby realizing a detachable connection between the displacement sensor and the outer pot 1, and facilitating the disassembly, assembly and maintenance of the displacement sensor.

[0029] It should be noted that, in this embodiment, the first fixing hole 121 and the second fixing hole 211 are both threaded holes, and bolts or screws are sequentially inserted into the second fixing hole 211 and the first fixing hole 121, so that the displacement sensor is fixedly installed on the bottom of the outer pot 1.

[0030] Specifically, the fixing platform 12 is formed by the outer bottom wall 11 of the outer pot 1 protruding outwards. When the displacement sensor is installed by bolts or screws, the bolts or screws are prevented from scratching the inner pot, and non-standard screws are not required.

[0031] It can be understood that in some other embodiments, the fixed platform 12 can also be a recessed platform. Installing the displacement sensor on the boss or recessed platform on the outer bottom wall 11 of the outer pot 1 can ensure that the displacement sensor is tightly connected to the sensing area in the pot, solving the traditional installation problem, improving assembly efficiency and sensor accuracy, and also reducing debugging costs and transportation costs.

[0032] Further, the outer bottom wall 11 is provided with a first groove 111, and at least one through hole 112 is opened on the bottom wall of the first groove 111. A hot plate is provided on the inner bottom wall of the outer pot 1, and the hot plate is fixedly connected to the outer pot 1. The hot plate is provided with at least one leg 113, and the leg 113 extends from the through hole 112, and the deformed end 22 abuts against the leg 113. Through the abutment between the deformed end 22 and the leg 113, the displacement sensor can timely and accurately sense the pressure change of the outer pot 1.

[0033] Furthermore, a contact point 221 facing the outer pot 1 is provided on the deformed end 22 , and the contact point 221 abuts against the outer bottom wall 11 , so that the displacement sensor can timely and accurately sense the pressure change of the outer pot 1 .

[0034] Furthermore, the outer pot 1 has a side wall 13, the fixed platform 12 extends to the connection between the outer bottom wall 11 and the side wall 13, and the fixed platform 12 is provided with at least one notch 122 at one end close to the side wall 13; the fixed end 21 includes a horizontal portion 212 and a bent portion 213, the horizontal portion 212 is close to the fixed platform 12, the bent portion 213 extends into the notch 122, and the bent portion 213 circumferentially abuts against the inner wall of the notch 122. The bent portion 213 is placed in the notch 122, and the side wall of the bent portion 213 circumferentially abuts against the inner wall of the notch 122, which can facilitate the displacement sensor to find an installation position, and after the displacement sensor is connected to the outer pot 1, the displacement sensor is prevented from rotating around the outer pot 1, thereby further improving the installation stability of the displacement sensor.

[0035] Further, at least two through holes 112 are provided in the first groove 111, and the hot plate is provided with at least two legs 113, each of which extends from a corresponding through hole 112. Specifically, the number of the legs 113 is equal to the number of the through holes 112, and they correspond one to one.

[0036] Furthermore, the fixed platform 12 is provided with two circumferentially distributed first fixing holes 121, and the fixed platform 12 is provided with two notches 122 at one end close to the side wall 13, which are also distributed circumferentially and can be used to install two sensors. The displacement sensor uses multiple displacement sensors to simultaneously detect the pressure change of the outer pot 1 to improve the accuracy of detection. The first groove 111 is provided with two through holes 112, and each through hole 112 is provided with a support foot 113. After each displacement sensor is fixedly installed on the fixed platform 12, the contact 221 of the displacement sensor corresponds to the support foot 113 one by one. The fixed platform 12 is provided with two notches 122 at one end close to the side wall 13, which are distributed circumferentially. Each displacement sensor can extend from the corresponding notch 122, thereby limiting each displacement sensor and preventing the displacement sensor from rotating relative to the outer pot 1.

[0037] The utility model uses the outer pot 1 as a fixed body for fixing the displacement sensor, and a raised fixing platform 12 is provided on the outer bottom wall 11 of the outer pot 1. Correspondingly, the displacement sensor has a fixed end 21 that can be installed on the fixed platform 12. The displacement sensor is installed on the outer bottom wall 11 of the outer pot 1 by bolts or screws to achieve stable installation of the displacement sensor. The deformation end 22 of the displacement sensor is located between the fixed end and the center of the outer bottom wall, and a contact 221 is provided on the deformation end 22, which abuts against the outer bottom wall 11 through the contact. When the internal pressure of the outer pot 1 changes, the main deformation of the outer pot 1 is concentrated on the outer bottom wall 11. Under the same pressure change, the deformation amount gradually decreases from the center of the outer bottom wall 11 to the edge. Therefore, the connection between the outer bottom wall 11 and the side wall 13 of the outer pot 1 is basically not deformed, thereby reducing the relative position change deviation between the fixed end 21 and the deformation end 22, effectively improving the sensitivity of the displacement sensor to the deformation degree of the outer pot 1, thereby improving the working stability of the electric pressure cooker. It can be understood that the two sensors may be two identical sensors or two different sensors.

[0038] Further, the deformed end 22 is located between the fixed end 21 and the center of the outer bottom wall 11. The fixed end 21 of the displacement sensor is fixed near the connection between the outer bottom wall 11 and the side wall 13 of the outer pot 1, and the deformed end 22 is close to the middle of the outer bottom wall 11. When the internal pressure of the outer pot 1 changes, the deformation of the outer pot 1 is mainly concentrated on the outer bottom wall 11 of the outer pot 1, and the deformation amount gradually decreases from the center to the edge of the outer bottom wall 11, so that the connection between the outer bottom wall 11 and the side wall 13 of the outer pot 1 is basically not deformed. When the internal pressure of the outer pot 1 changes, the position of the fixed platform 12 is basically not affected, so that the fixed end 21 of the displacement sensor can maintain a basically stable position, and the deformed end 22 is located near the center of the outer bottom wall 11 and is against the outer bottom wall 11. When the internal pressure of the outer pot 1 changes, the deformation of the center of the outer bottom wall 11 is relatively large, so that the deformed end 22 can be displaced relatively greatly relative to the fixed end 21. The displacement sensor can timely and accurately sense the pressure change of the outer pot 1, improve the sensitivity and accuracy of the displacement sensor in detecting the deformation degree of the bottom of the outer pot 1, and thus enhance the working stability of the electric pressure cooker.

[0039] In another embodiment, Figures 1 to 4 As shown, the utility model also provides a cooking device, including an outer pot structure. Specifically, the cooking device is an electric pressure cooker, and the technical effect of the electric pressure cooker is similar to the technical effect of the outer pot structure mentioned above, which will not be repeated here.

Obviously, the described embodiments are only some embodiments of the utility model, rather than all embodiments. Based on these embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
