[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] The directions described in the utility model specification, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions of the drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.

[0028] like Figures 1 to 5 As shown, a pressure cooker structure with switchable cooking modes comprises a pot body 11 and a pot cover 2 which can be covered thereon, wherein the pot body 1 is provided with a control module 11 for controlling the operation of the pressure cooker, the top of the pot cover 2 is provided with an exhaust valve block 21 which can slide up and down relative to the pot cover, the pot cover 2 is also provided with a toggle member 22, a seesaw member 23, and a sliding member 24, the toggle member 22 is rotatably connected to the pot cover 2, the toggle member 22 is connected with a knob member 25 which is held by a hand and then pushed to rotate, the middle part of the seesaw member 23 is rotatably connected to the pot cover 2, the front part of the seesaw member 23 is located below the toggle member 22 and the rear part of the seesaw member 23 is located below the exhaust valve block 21, the bottom of the toggle member 22 is provided with a pressing portion 221 which can press down the front part of the seesaw member 23 during its rotation and thereby make the rear part of the seesaw member 23 lift up the exhaust valve block 21, The sliding member 24 is slidably connected to the pot cover 2. The pot body 1 is provided with a proximity sensor 12 for sensing the sliding member 24. The proximity sensor 12 is electrically connected to the control module 11. A linkage structure 26 is provided between the toggle member 22 and the sliding member 24, which can push the sliding member 24 to approach or move away from the proximity sensor 12 during the rotation of the toggle member 22. The proximity sensor 12 can be a general photoelectric sensor, a capacitive sensor, a magnetic sensor, an ultrasonic sensor, an electric induction sensor, etc., as long as it can sense the approach or distance of the sliding member 24, that is, whether the entire or local structure of the sliding member 24 is within a preset distance. The knob member 25 can be directly connected to the toggle member 22, or the two can be connected through a transmission structure so that the rotation can be transmitted between the knob member 25 and the toggle member 22. Figure 6As shown, when in use, the knob 25 is manually turned clockwise to push the toggle member 22 to rotate. During the rotation of the toggle member 22, the seesaw member 23 is pushed to lift the exhaust valve block 21, so that the pressure cooker is in a deflated state. At the same time, during the rotation of the toggle member 22, the sliding member 24 is pushed away from the proximity sensor 12. After detecting that the sliding member 24 is away, the proximity sensor 12 sends a signal to the control module 11, and the control module 11 sets the working mode of the pressure cooker to the rice cooker mode; similarly, when the knob 25 is manually turned counterclockwise, the exhaust valve block 21 falls after the top pressure part 221 leaves the seesaw member 2, so that the pressure cooker is in a closed state. At the same time, during the rotation of the toggle member 22, the sliding member 24 is pushed close to the proximity sensor 12. After detecting that the sliding member 24 is close, the proximity sensor 12 sends a signal to the control module 11, and the control module 11 sets the working mode of the pressure cooker to the pressure cooker mode. Of course, when the pressure cooker is in the pressure cooker mode, the slider 24 can be away from the proximity sensor 12, and when the pressure cooker is in the rice cooker mode, the slider 24 can be close to the proximity sensor 12. In this way, the control module 11 can determine the state of the pressure cooker, and then set different working powers and working times according to different states, such as timing function, automatic alarm function, etc., which ultimately makes the user's operation more convenient and the use of the appliance safer.

[0029] As a preferred solution of this embodiment, Figure 5 As shown, the toggle member 22 is provided with a limiting arm plate 222 at an angle, and the pot cover 2 is provided with a limiting convex plate 27 located between the two limiting arm plates 222 to prevent the limiting arm plates 222 from moving, so that the toggle member 22 stops rotating after rotating clockwise to the forward rotation end position, and the toggle member 22 stops rotating after rotating counterclockwise to the reverse rotation end position, as shown in FIG. Figure 6 As shown, after the toggle member 22 rotates clockwise, it is blocked by the limiting convex plate 27 and reaches the clockwise end position P1, and after the toggle member 22 rotates counterclockwise, it is blocked by the limiting convex plate 27 and reaches the reverse end position P2. Of course, the toggle member 22 may not be provided with a limiting structure around it, so that the toggle member 22 can rotate 360 ​​degrees, as long as the pressing portion 221 can press down the front of the rocker member 23 when the toggle member 22 rotates to a specific angle, so that the rear of the rocker member 23 lifts the exhaust valve block 21 upward, and at this time, the proximity sensor 12 is located close to the sliding member 24.

[0030] As a preferred solution of this embodiment, Figures 4 to 6As shown, a limiting groove 271 is provided on the side wall of the limiting convex plate 27, and a first limiting protrusion 223 is provided on the toggle member 22, which can be inserted into the limiting groove 271 when the toggle member 22 is located at the forward rotation end position P1, and a second limiting protrusion 224 is provided on the toggle member 22, which can be inserted into the limiting groove 271 when the toggle member 22 is located at the reverse rotation end position P2. In this way, when the toggle member 22 is located at the forward rotation end position P1 or the reverse rotation end position P2 during its rotation, there is less damping, and the user can more easily rotate the toggle member 22 to the forward rotation end position P1 or the reverse rotation end position P2, which makes the operation smoother and gives the user a vibration feedback, and can also improve the accuracy of the structure.

[0031] As a preferred solution of this embodiment, Figure 4 and Figure 5 As shown, the toggle member 22 is provided with an arc-shaped elastic sheet 225, and the first limiting protrusion 223 and the second limiting protrusion 224 are arranged on the elastic sheet 225. Through the elastic force of the elastic sheet 225, the first limiting protrusion 223 and the second limiting protrusion 224 are pressed toward the limiting convex plate 27, so that the first limiting protrusion 223 and the second limiting protrusion 224 can be stuck in the limiting groove 271. At the same time, when the user rotates the toggle member 22, due to the deformation of the elastic sheet 225, the first limiting protrusion 223 and the second limiting protrusion 224 can also be smoothly disengaged from the limiting groove 271, and the operation is smoother and more convenient.

[0032] As a preferred solution of this embodiment, Figure 5 As shown, the linkage structure 26 includes a strip groove 226 provided on the toggle member 22, and a push rod 241 provided on the sliding member 24 and extending into the strip groove 226, so that after the toggle member 22 rotates a certain angle, the groove walls at both ends of the strip groove 226 contact the push rod 241, and then push the push rod 241 to make the sliding member 24 slide relative to the pot cover 2, instead of the sliding member 24 following the toggle member 22 to continuously move, so as to improve the detection accuracy of the proximity sensor 12.

[0033] As a preferred solution of this embodiment, Figure 3 and Figure 5 As shown, the pot cover 2 is provided with an arc-shaped slide groove 28, and the sliding member 24 includes a sliding seat 242 that matches the shape of the arc-shaped slide groove 28, so that the sliding member 24 can slide circumferentially relative to the pot cover 2, and the length direction of the strip groove 226 extends circumferentially, and the center position of the arc-shaped slide groove 28, the center position of the strip groove 226, and the rotation center position of the toggle member 22 are consistent.

[0034] In this embodiment, the sliding member 24 also includes an extension arm 243 connected to the sliding seat 242 and extending outward. The proximity sensor 12 is an inductive sensor. The end of the extension arm 243 is provided with a accommodating cavity 245 for accommodating a metal part. Compared with proximity sensors such as photoelectric sensors, capacitive sensors, magnetic sensors, and ultrasonic sensors, inductive sensors can have better penetration and can detect metal parts through a thicker wall. The metal part can be a general steel block or iron block.

[0035] As a preferred solution of this embodiment, Figure 3 and Figure 6 As shown, the knob member 25 is connected to a button member 29 which can slide up and down relative to the knob member 25, and a push rod 291 is provided at the bottom of the button member 29. The bottom end of the push rod 291 passes through the knob member 25 and the swing member and reaches the upper front part of the seesaw member 23. In this way, when the pressure cooker is in the pressure cooker mode, the user can open the exhaust valve block 21 by pressing the button member 29 to balance the air pressure of the pressure cooker and the outside world, and finally facilitate the user to open the lid in this mode.

[0036] As a preference, Figures 4 to 6 As shown, the front part of the seesaw member 23 has a guide flange 231 at a position corresponding to the pressing portion 221, so as to facilitate the pressing portion 221 to slide to the top of the front part of the seesaw member 23. Preferably, a rounded or arc-shaped guide surface can also be provided on the pressing portion 221. The front end of the seesaw member 23 is provided with an extension portion 232 extending forward to the bottom of the pressing rod 291.

[0037] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
