The user can unlock the latch by the unlocking operation of the locking device through the cover opening operation so that the steam cover plate 22 can be opened from the cover closing position. Preferably, the locking means may be a push-button or the like. The steam cover 22 can be locked when pressed towards the lid 10 and unlocked when pressed again towards the lid 10. Therefore, structures such as an uncovering button and the like can be omitted, and unnecessary parts are reduced. Preferably, a biasing member such as a torsion spring may also be provided to automatically move the steam cover 22 to the open position when the latch is unlatched.

Referring again to fig. 2 to 4, the lid assembly 1 further comprises a locking device 30 disposed on the lid 10 for locking the steam cover 22 of the steam generating device 20 in a covering position when the lid 10 is opened relative to the pot body 2, so as to prevent water in the steam generating cavity from flowing out due to accidental opening. According to the utility model discloses, locking device 30 can open to being greater than when predetermined angle automatically under the effect of gravity the locking to steam cover plate 22 at lid 10 for the horizontal plane to close automatically under the effect of gravity and remove the locking to steam cover plate 22 when being less than within the predetermined angle at lid 10 for the horizontal plane lid. Thereby, it is possible to automatically lock or unlock by gravity in response to the position state of the lid body 10, the trouble of manual operation is eliminated, and the reliability is high.

Specifically, the locking device 30 includes a locking member 31 and a weight member 32. Wherein the locking member 31 is configured to be movable between a locking position (see fig. 3) and an unlocking position (see fig. 4). When the locking member 31 is in the locking position, it is capable of locking the steam cover 22 in the closed position. At this time, even if the user performs the operation of opening the steam cover 22, the steam cover 22 cannot be opened, thereby ensuring safety. When the locking member 31 is located at the unlocking position, it releases the locking of the steam cover 22, and the user can open the steam cover 22 to perform a desired operation.

The weight 32 is fixedly connected to the locking member 31. The fixed connection prevents the weight member 32 and the locking member 31 from hitting each other during the movement to generate noise or give a jerky feeling. The weight 32 has a large mass so that its weight is large enough to drive the locking member 31 between the locked and unlocked positions. In the present embodiment, the locking member 31 has an accommodation cavity 311, and the weight member 32 is fixed in the accommodation cavity 311. This makes it possible to substantially coincide the position of the center of gravity of the weight member 32 with the position of the center of gravity of the locking member 31, facilitating the movement of the two integrally.

The weight 32 may be made of a material such as metal, glass, plastic, or ceramic. Thus, even if the weight 32 has a small volume, it can have a large gravity. In the illustrated embodiment, the weight 32 is configured as a sphere. However, the weight 32 may also be configured as a cylinder, square, cone, or any other suitable shape.

As shown in fig. 2 to 4, a slide groove 12 is provided in the lid body 10, and the slide groove 12 has a support surface 121. The locking member 31 is disposed within the slide channel 12 and is slidable along the support surface 121 between an unlocked position and a locked position. Wherein the support surface 121 is configured to be inclined downward in a horizontal direction away from the steam cover plate 22 in a state where the lid body 10 is horizontally placed. For example, the inclination angle of the support surface 121 is set to α. When the lid 10 is placed horizontally, the support surface 121 is inclined with respect to the horizontal plane and is positioned lower away from the steam cover plate 22. The locking member 31 slides along the support surface 121 to a lower position (i.e., an unlocked position) under the force of the weight 32, away from the steam cover 22. The locking member 31 remains stationary during the time the lid body 10 is opened from horizontal to an angle alpha relative to the horizontal. Once the opening angle of the lid body 10 with respect to the horizontal plane is greater than α, the position of the support surface 121 adjacent to the steam cover 22 becomes the low position, i.e., the position of the locking member 31 is higher than the position of the steam cover 22. At this point, the locking member 31 automatically slides along the support surface 121 to a low position adjacent the steam cover 22 under the influence of gravity, thereby locking the steam cover 22 in the closed position.

Specifically, as shown in fig. 2, the locking member 31 is provided with a projection 312. Accordingly, the steam cover plate 22 is provided with a slot. Illustratively, when the locking member 31 is in the locked position, the protrusion 312 is inserted into the slot to prevent the steam cover 22 from opening. Alternatively, the locking member may be provided with a slot and the steam cover plate with a protrusion, or both the steam cover plate and the locking member may be provided with mating slots and protrusions.

The angle α is a predetermined angle for triggering the movement of the lock member 31. Preferably, α may be 18 ° to 25 °. For example, α may be specifically 20 °, 22 °, 24 ° or any value within the above range.

Turning again to fig. 2, 3 and 4, the locking device 30 preferably further comprises a bumper 33 made of a flexible material such as silicone or rubber. The buffer member 33 is fixed in the receiving cavity 311 of the locking member 31 and at least partially separates the locking member 31 from the weight member 32 to perform a buffering function, thereby further reducing noise and jerk caused by impact. It will be appreciated that the likelihood and strength of the impact between the weight member 32 and the locking member 31 is greater in the direction of movement of the locking member 31. Therefore, the cushion member 33 may be provided only at a necessary position between the locking member 31 and the weight member 32 in the moving direction of the locking member 31, and the cushion member 33 may not be provided at other positions (e.g., other positions where no impact is generated). Thereby saving material. Of course, the damping element 33 can also be used to completely or largely surround the weight element 32 for reasons of safety.

In the present embodiment, the cushion member 33 is configured in a U-shaped configuration. The weight member 32 is sandwiched between the two opposite side arms 331 and 33 of the U-shaped structure, and further the weight member 32 and the buffer member 33 are integrally inserted or snapped into the receiving cavity 311 of the locking member 31. It can be understood that the side walls of the weight member 32 and the receiving cavity 311 and the side arms 331 of the buffer member 33 apply clamping force to firmly hold the weight member 32 and the buffer member 33 in the receiving cavity 311.

Preferably, the lateral side walls 331 and the lateral side surfaces of the buffer 33 are provided with a projection 332. Accordingly, a pair of opposite side walls of the receiving cavity 311 of the locking member 31 is provided with catching grooves 313. During the process of inserting the buffer member 33 into the accommodating cavity 311, the protrusions 332 are clamped into the corresponding clamping grooves 313, so as to further improve the installation firmness of the weight member 32 and the buffer member 33. It is further preferable that the size of the projection 332 in a natural state is larger than that of the card slot 313, and the projection 332 has a cavity. The cavity allows the protrusion 332 to elastically deform better to accommodate the size of the slot 313 while providing improved cushioning against impact. And the convex block 332 in the clamping groove 313 has the tendency of elastic recovery, so that the acting force of the convex block 332 and the clamping groove 313 is increased, and the firm installation is further kept.

In the above embodiment, the lock member 31 is moved between the lock position and the unlock position in such a manner as to slide along the support surface 121. However, it is understood that as an alternative embodiment, the locking member 31 may also be configured to move between the locked and unlocked positions in a manner that rotates about a pivot axis
