[0027] In some embodiments, in order to achieve the locking of the locking assembly 3 with the pot body 1, the locking assembly 3 includes a connecting rod 31 and an annular lock buckle 32. One end of the connecting rod 31 is fixed on the cover assembly 2 and can rotate around the center of the pot body 1. The annular lock buckle 32 is connected to the other end of the connecting rod 31. The connecting rod 31 is used to drive the annular lock buckle 32 to rotate when rotating, so that the pot teeth on the annular lock buckle 32 are locked with the pot teeth on the pot body 1.

[0028] Furthermore, the cover assembly 2 includes a cover 21 and a lining 22 which are arranged in sequence from close to the pot body 1 to away from the pot body 1, the connecting rod 31 is located on the other side of the lining 22 opposite to the cover 21, one end of the connecting rod 31 is fixed on the lining 22, the annular lock buckle 32 is located below the lining 22 and is arranged around the cover 21 and the pot body 1, a hanging shaft is provided on the annular lock buckle 32, and an arc-shaped avoidance groove 221 is provided on the lining 22. The hanging shaft passes through the avoidance groove 221 to be connected to the other end of the connecting rod 31. When the connecting rod 31 rotates, the hanging shaft moves in the arc-shaped avoidance groove 221 to drive the annular lock buckle 32 to rotate.

[0029] Furthermore, in order for the magnetically sensitive float assembly 4 to limit the connecting rod 31, when the connecting rod 31 is rotated until the pot teeth on the annular lock buckle 32 are locked with the pot teeth on the pot body 1, an escape position is formed on one side of the connecting rod 31, and the magnetically sensitive float assembly 4 moves to pass through the escape position to limit the connecting rod 31.

[0030] In some embodiments, in order to drive the rotation of the connecting rod 31, the electric rice cooker capable of pressure-induced opening prevention and pressure detection also includes a motor 6 and a transmission member 7. The motor 6 is fixed on the cover assembly 2, and the transmission member 7 is arranged on the motor 6 and connected to the connecting rod 31. The transmission member 7 is used to drive the connecting rod 31 to rotate under the drive of the motor 6.

[0031] Furthermore, the transmission member 7 is a gear, a slot 311 is provided on the connecting rod 31, and meshing teeth are provided on the inner wall of the slot 311. The gear is located in the slot 311 and meshed with the meshing teeth. Under the drive of the motor 6, the gear rotates to drive the connecting rod 31 to rotate.

[0032] In some embodiments, in order for the magnetically sensitive float assembly 4 to realize the limiting function of the connecting rod 31, the cover assembly 2 includes a cover 21 and a lining 22 which are arranged in sequence from close to the pot body 1 to far away from the pot body 1, the cover 21 is provided with an air outlet 211, the lining 22 is provided with a mounting hole, the magnetically sensitive float assembly 4 includes a mounting seat 41 and a magnetically sensitive float 42, the mounting seat 41 is installed in the mounting hole, the magnetically sensitive float 42 is movably arranged in the mounting seat 41, the pressure in the pot body 1 acts on the magnetically sensitive float 42 through the air outlet 211, and the magnetically sensitive float 42 is used to move under the action of the pressure in the pot body 1 to limit the locking assembly 3.

[0033] Furthermore, a slide groove 411 and an avoidance hole connected to the slide groove 411 are provided on the mounting seat 41, and the magnetic sensitive float 42 is slidably arranged in the slide groove 411. Under the action of the pressure in the pot body 1, one end of the magnetic sensitive float 42 passes through the avoidance hole to limit the locking assembly 3.

[0034] Furthermore, considering that when there is no pressure in the pot body 1, the magnetic float 42 needs to be reset to release the limit on the connecting rod 31, the magnetic float assembly 4 also includes an elastic reset member 44. A limit block 421 is provided in the middle of the magnetic float 42. The elastic reset member 44 is sleeved in the slide groove 411 and sleeved on the end of the magnetic float 42 close to the locking assembly 3. The two ends of the elastic reset member 44 respectively abut the inner wall surface of the slide groove 411 and the limit block 421. When there is pressure in the pot body 1, the magnetic float 42 moves toward the direction of the connecting rod 31 under the action of pressure and compresses the elastic reset member 44. When there is no pressure in the pot body 1, the elastic reset member 44 stretches and drives the magnetic float 42 to reset.

[0035] In some embodiments, the magnetic sensitive float assembly 4 further includes a float sealing ring 43, which is sleeved outside the mounting seat 41 and located between the cover plate 21 and the liner 22. The float sealing ring 43, the mounting seat 41 and the cover plate 21 enclose a sealed cavity connected to the air outlet 211, and the float sealing ring 43 is used to release pressure when the pressure in the pot body 1 reaches a preset overpressure relief pressure. With such a design, the electric rice cooker integrates air pressure prevention, pressure detection and overpressure relief through the mutual cooperation of the locking assembly, the magnetic sensitive float assembly and the magnetic sensitive switch, thereby further simplifying the structure of the electric rice cooker and reducing the production cost of the electric rice cooker.

[0036] Furthermore, in order for the float sealing ring 43 to achieve the sealing and pressure relief functions, the float sealing ring 43 includes a mounting portion 431, a first bending portion 432 and a second bending portion 433. The mounting portion 431 is mounted on the lining 22, one end of the first bending portion 432 is connected to the mounting portion 431, and the second bending portion 433 is connected to the other end of the first bending portion 432. The first bending portion 432 and the second bending portion 433 together form an inwardly buckled shape, and a sealed cavity is formed between the first bending portion 432, the second bending portion 433 and the cover plate 21. When the pressure in the pot body 1 reaches a preset overpressure relief pressure, the second bending portion 433 is folded outward relative to the first bending portion 432, so that the pot body 1 is connected to the external environment through the air outlet 211.

[0037] The following is a detailed description of the process of pressure-starting and opening prevention, pressure detection and overpressure relief of the rice cooker:

[0038] When the connecting rod 31 drives the annular lock buckle 32 to rotate until the annular lock buckle 32 and the pot body 1 are in a locked state, the upper part of the magnetic sensitive float 42 is the escape position of the connecting rod 31. At this time, if there is pressure in the pot body 1, the magnetic sensitive float 42 passes through the escape position of the connecting rod 31, resulting in that the connecting rod 31 cannot rotate in the direction of opening the lid. This is the pressure-generating method to prevent the lid from opening. At the same time, since the magnetic sensitive float 42 rises and approaches the magnetic sensitive switch 5, the magnetic sensitive switch 5 senses the magnet on the magnetic sensitive float 42, and a pressure-generating signal is sent to the circuit board of the rice cooker. This is the pressure-generating method to prevent the lid from opening. The pressure detection inside the pot body 1 is performed. At this time, if the pressure inside the pot body 1 continues to rise and reaches the set overpressure, the second bent portion 433 in the sealed cavity formed by the float sealing ring 43, the mounting seat 41 and the cover plate 21 will turn outward to achieve pressure relief. This is the overpressure relief function. When the pressure inside the pot body 1 drops to no pressure, the magnetic float 42 drops under the action of the elastic reset member 44, and the magnetic float 42 moves away from the magnetic switch 5. The magnetic switch 5 then gives a no-pressure signal to the circuit board of the rice cooker. This is the zero-pressure detection function.

[0039] The utility model provides an electric rice cooker capable of pressure-induced opening prevention and pressure detection. The electric rice cooker comprises a pot body 1, a cover assembly 2, a locking assembly 3, a magnetically sensitive float assembly 4 and a magnetically sensitive switch 5. The cover assembly 2 can be detachably covered on the pot body 1. The locking assembly 3 can be movably arranged on the cover assembly 2. The locking assembly 3 can be moved relative to the cover assembly 2 to be locked with the pot body 1 so that the cover assembly 2 is locked with the pot body 1. The magnetically sensitive float assembly 4 can be movably arranged on the cover assembly 2. When the cover assembly 2 is locked with the pot body 1, the magnetically sensitive float assembly 4 can be moved relative to the cover assembly 2 under the action of the pressure in the pot body 1 to limit the locking assembly 3 so that the locking assembly 3 is kept in a locked state. The magnetically sensitive switch 5 is arranged on the cover assembly 2 and is used for sensing the movement of the magnetically sensitive float assembly 4 to detect the pressure in the pot body 1. By adopting such a design, the locking assembly 3, the magnetic sensitive float assembly 4 and the magnetic sensitive switch 5 cooperate with each other, so that the electric rice cooker can simultaneously realize the pressure-starting anti-opening and pressure detection functions, thereby simplifying the structure of the electric rice cooker and reducing the production cost of the electric rice cooker.

[0040] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
