Wherein the locked position corresponds to the first position and the unlocked position corresponds to the second position, i.e. the locking device 310 is movable from the locked position to the unlocked position when the transmission 320 is moved from the first position to the second position.

The actuator 320 preferably includes a slider 322, and one end of the slider 322 has a slope 321, and the slope 321 is in contact with the steam cover 122, specifically, when the steam cover 122 is closed, the steam cover 122 can push the slope 321 downwards, and the slope 321 can move the slider 322 from the first position to the second position when being pushed. For example, the first latch 127 disposed on the steam cover 122 may be used as a trigger for pushing the slope 321, so as to simplify the structure of the cover.

The linkage 300 also includes a biasing member, which may be configured as a spring 330. One end of the spring 330 is connected to the slider 322, and the other end is fixedly connected to the cover 110, so that the spring 330 is compressed when the slider 322 moves from the first position to the second position, so that the spring 330 is in a deformed state. The slider 322 may return to the first position from the second position under the restoring force of the spring 330 when the steam cover 122 is opened, and the locking device 310 is configured to be movable from the unlocked position to the locked position when the slider 322 is moved from the second position to the first position.

As shown in fig. 5 and 6, the locking device 310 includes a locking arm 311 and a supporting shaft 312 supporting the locking arm 311. The supporting shaft 312 is located outside the slider 322 and is fixedly disposed in the cover body 110, the locking arm 311 is rotatably connected to the supporting shaft 312, the locking arm 311 has a first end and a second end opposite to the first end, the first end is connected to the slider 322 and can move together with the slider 322, and the second end has an arc-shaped wall 313. When the first end moves with the slider 322, the arc-shaped wall 313 of the second end can rotate around the support shaft 312 between the locked position and the unlocked position.

The locking device 310 is configured such that the curved wall 313 abuts against a back side of the first fastener 123 when in the locked position to limit movement of the first fastener 123 such that the first fastener 123 cannot be disengaged from the second fastener, and such that the curved wall 313 is spaced away from the back side of the first fastener 123 when in the unlocked position to enable the first fastener 123 to be disengaged from the second fastener.

In order to achieve enlargement of the stroke of the second end of the locking arm 311, it is preferable that the minimum distance L1 between the first end and the support shaft 312 is smaller than the minimum distance L2 between the second end and the support shaft 312. Further preferably, the ratio of the minimum distance L1 between the first end and the support shaft 312 to the minimum distance L2 between the second end and the support shaft 312 is 1: 3. preferably, the minimum distance between the first end and the support shaft 312 is greater than 3 mm.

Preferably, the minimum distance L1 between the first end and the supporting shaft 312 is greater than the moving stroke L3 of the transmission 320 moving from the first position to the second position, wherein L3 may be 3-6 mm.

In operation, when the steam cover plate 122 is closed, as shown in fig. 4, the steam cover plate 122 pushes the inclined surface 321 downward, and the inclined surface 321 moves the slider 322 from the first position to the second position under the pushing action. Because the first end of the locking arm 311 is connected to the slider 322, the first end of the locking arm 311 moves to the second position along with the slider 322, and meanwhile, the second end of the locking arm 311 rotates to be away from the first fastener 123, so that the lid opening and closing mechanism can be normally operated by the lid opening and closing button 124, and the lid 110 can be opened relative to the cooker body 210.

When the steam cover 122 is opened, as shown in fig. 3, the slider 322 returns from the second position to the first position under the action of the spring 330. Because the first end of the locking arm 311 is connected to the slider 322, the first end of the locking arm 311 moves to the first position along with the slider 322, and meanwhile, the second end of the locking arm 311 rotates to the back of the first fastener 123 along the direction opposite to the rotating direction to abut against the first fastener 123, so as to limit the movement of the first fastener 123, so that the first fastener 123 cannot be disengaged from the second fastener, and the cover 110 cannot be opened relative to the cooker body 210.

According to the utility model discloses a cooking utensil is through setting up link gear 300 to make link gear 300 respond to opening of steam apron 122 and lock lid 110 in the closed position, this scheme can guarantee to lock lid 110 in the closed position when steam apron 122 is opened, also makes lid 110 unable open, thereby can avoid the liquid outflow in the steam generation chamber. The scheme is ingenious in design and convenient to realize.

The utility model also provides a cooking utensil, this cooking utensil includes a kind of deep pot body 210, lid 110, lid switching mechanism, steam generator 120 and link gear. In the present embodiment, the linkage mechanism may be configured to act on the steam cover opening and closing mechanism in response to the action of the cover opening and closing mechanism, so that the steam cover 122 is locked in the closed position when the cover 110 is opened. This arrangement ensures that the steam cover 122 is in the closed position when the cover 110 is opened, thereby preventing liquid from escaping from the steam generating chamber.

The link mechanism is substantially the same as the link mechanism 300 described above, except that the link mechanism in the present embodiment is provided in the reverse direction with respect to the link mechanism 300. Specifically, when the cover body is closed, the cover body can act on the linkage mechanism, and for example, the first buckling piece on the cover body can be used as a trigger piece acting on the linkage mechanism, so that the structure of the cover body is simplified. And the linkage mechanism can move so as to be far away from the first fastener or the second fastener, so that the steam cover plate can be normally opened. When the cover body is opened, the linkage mechanism can generate reverse motion under the action of the spring, so that the linkage mechanism moves to the back of the first buckle part or the second buckle part and abuts against the first buckle part or the second buckle part to limit the motion of the first buckle part or the second buckle part, the first buckle part cannot be disengaged from the second buckle part, and the steam cover plate cannot be opened.
