That is, the opening and closing of the cover 2 is achieved by the movement of the latch assembly 22.

The rotating cover opening assembly is connected with the locking assembly 22 and used for driving the locking assembly 22 to move between the locking position and the separating position, specifically, the rotating cover opening assembly is the rotating cover opening assembly of the cooking utensil of the invention, and the poke rod of the poke rod in the rotating cover opening assembly is connected with the locking assembly 22. The rotary cover-opening assembly is a component having an automatic driving function, and the rotary cover-opening assembly can realize the conversion of the latch assembly 22 between the locking position and the separating position by hydraulic pressure, pneumatic pressure, electric drive and the like.

Referring to fig. 4 and 5, fig. 4 shows the latch assembly in either the locked or unlocked position, and fig. 5 shows the latch assembly between the locked and latched positions.

According to the cover body 2 of the cooking utensil provided by the embodiment of the invention, the rotary cover opening assembly is arranged, and the movement of the lock catch assembly 22 is realized through the rotary cover opening assembly, so that the opening and closing of the cover body 2 are labor-saving, and the automation degree of the cooking utensil is improved.

In addition, when the cooking utensil is used, high pressure may exist in the cooking utensil, and a danger source can be far away from people by automatically driving the switch cover body 2, so that the safety performance of the cooking utensil is improved.

When the torque received by the rotating hand 233 is not less than the predetermined value, the rotating seat 2311 and the rotating head 2312 can be relatively rotated, so that the rotating seat 2311 and the driving unit 232 can rotate relatively, and the problem that the driving unit 232 affects the manual switch cover 2 is avoided.

Wherein, the preset value is determined according to actual use and can be set into a form which can be opened by an ordinary adult.

In the embodiment of the present invention, the locking assembly 22 is positioned and installed on the inner cap assembly 21 to be easily rotated. The reduction motor (driving unit 232) is fixedly installed on the inner lid assembly 21, and a shaft of a rotation core 2314 of the reduction motor has characteristics of low speed and large torque. When the power is cut off, the output mandrel cannot be twisted by external force. The protruding end fork slot of the rotating seat 2311 may position the locking post (part of the locking assembly 22), i.e., the rotating seat 2311 drives the locking post to rotate together. The rotary head 2312 is positioned and mounted at the output spindle of the gearmotor, i.e. the output spindle of the gearmotor and the rotary head 2312 rotate together. The steel balls and the elastic portions 2316 are installed in the through holes of the rotary core 2314, that is, the steel balls can compress the elastic portions 2316 to be displaced and contracted in the through holes of the rotary core 2314. The assembly of the rotating core 2314 is buckled and installed in the clamping groove of the rotating head 2312, namely the buckling force of the steel ball elastic mechanism is greater than the rotating torque force of the rotating head 2312, so that the rotating head 2312 drives the rotating core 2314 to rotate. The rotation seat 2311 is positioned and installed at the rotation core 2314, that is, the rotation core 2314 and the rotation seat 2311 may rotate together. The knob 233 is locked to the swivel base 2311 by a screw, that is, the swivel base 2311 and the knob 233 can be rotated together. After the speed reducing motor is powered off, the output spindle of the speed reducing motor cannot rotate due to the fact that the output rotating torque is large.

At this time, the manual rotation knob 233 is provided with a clutch mechanism to open the lid manually, and the rotation torque of the rotation knob 233 is larger than the engagement force of the steel ball elastic mechanism of the rotation core 2314 and the rotation torque of the rotation head 2312, so that they are disengaged. Therefore, the rotating head 2312 and the speed reducing motor are fixed and do not rotate, but the rotating hand 233 can be manually rotated to take the rotating seat 2311 to open the cover.
