The heating device may in particular be a heating tube, a heating plate, an electromagnetic heating coil or the like, which may preferably be arranged below or at the side of the steam generating chamber.

In addition, the steam generating device 20 further includes a steam cover 22. The steam cover 22 is connected to the lid 10 and is movable relative to the lid 10 between a closed position and an open position. The side of the steam cover plate 22 facing the steam generating chamber is provided with a seal. When the steam cover plate 22 is in the closed position, as shown in FIG. 2, the steam cover plate 22 is capable of covering and sealing the steam generating chamber to prevent water and/or steam from leaking therefrom. Preferably, the upper surface of the steam cover plate 22 forms a part of the upper surface of the lid body 10. This preferred solution makes the construction of the cover assembly 1 more compact. As shown in fig. 3, when the steam cover 22 is in the open position, the steam generating chamber is opened and communicates with the outside, so that the user can add water into the water container 21 or take out the water container 21 for cleaning. Preferably, the steam cover plate 22 may be connected to the cover body 10 by a pivot shaft so as to be pivotally switched between the closed position and the open position about the pivot axis.

Further, as shown in fig. 1, a locking device 40 is provided on the cover body 10. Accordingly, the steam cover plate 22 is provided with a latch 221. When the steam cover plate 22 is in the closed position, the locking device 40 can lockingly clamp the latch 221, so that the steam cover plate 22 is fixed in the closed position. The user can unlock the latch 221 from the locking device 40 by the cover opening operation, so that the steam cover plate 22 can be opened from the cover closing position. Preferably, the locking device 40 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 locking device 40 is unlocked.

Referring again to fig. 1 to 3 and fig. 6, the lid assembly 1 further comprises a locking device 40 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 chamber from flowing out due to accidental opening. According to the utility model discloses, locking device 40 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 for the horizontal plane lid at lid 10. 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, as shown in fig. 4 and 5, the locking device 40 includes a locking member 41 and a weight member 42. Wherein the locking member 41 is configured to be movable between a locked position (see fig. 6 and 7) and an unlocked position (see fig. 2 and 3). When the locking member 41 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 41 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 member 42 is fixedly connected to the locking member 41. The fixed connection prevents the weight member 42 and the locking member 41 from hitting each other during the movement to generate noise or give a jerky feeling. The weight member 42 has a large mass so that its weight force is large enough to drive the locking member 41 between the locking position and the unlocking position. In the present embodiment, the locking member 41 has the accommodation chamber 411, and the weight member 42 is fixed in the accommodation chamber 411. This makes it possible to substantially match the position of the center of gravity of the weight member 42 with the position of the center of gravity of the locking member 41, facilitating the movement of the two integrally.

The weight member 42 may be made of a material such as metal, glass, plastic, or ceramic. Thus, even if the weight member 42 has a small volume, it can have a large gravity. In the illustrated embodiment, the weight 42 is configured as a sphere. However, the weight member 42 may also be configured in a cylindrical, square, conical, or any other suitable shape.

As shown in fig. 7, a chute 11 is provided in the lid body 10, and the chute 11 has a support surface 111. The locking member 41 is disposed in the slide groove 11, and is slidable along the support surface 111 between an unlocked position and a locked position. Wherein the support surface 111 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 111 is set to α. When the cover 10 is horizontally placed, the support surface 111 is inclined with respect to the horizontal plane and is located lower away from the steam cover plate 22. The locking member 41 slides along the support surface 111 to a lower position (i.e., unlocked position) under the force of the weight member 42, away from the steam cover 22. The locking member 41 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 cover body 10 with respect to the horizontal plane is greater than α, the position of the support surface 111 adjacent to the steam cover plate 22 becomes the low position, i.e., the position of the locking member 41 is higher than the position of the steam cover plate 22. At this point, the locking member 41 automatically slides along the support surface 111 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. 5, the locking member 41 is provided with a projection 413. Accordingly, as shown in FIG. 1, the steam cover 22 is provided with slots 222. Referring again to fig. 7, when the locking member 41 is in the locking position, the protrusion 413 is inserted into the insertion groove 222 to prevent the steam cover 22 from being opened. 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 41. 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. 4 and 5, the locking device 40 preferably further includes a bumper 43 made of a flexible material such as silicone or rubber. The buffer member 43 is fixed in the receiving cavity 411 of the locking member 41 and at least partially separates the locking member 41 from the weight member 42 to perform a buffering function, thereby further reducing noise and jerk caused by impact. It will be appreciated that the possibility and strength of the impact between the weight member 42 and the locking member 41 is greater in the moving direction of the locking member 41. Therefore, the cushion member 43 may be provided only at a necessary position between the locking member 41 and the weight member 42 in the moving direction of the locking member 41, and the cushion member 43 may not be provided at other positions (e.g., other positions where no impact is generated). Thereby saving material. Of course, the damping element 43 can also be used to completely or largely surround the weight element 42 for reasons of safety.

In the present embodiment, the cushion member 43 is configured in a U-shaped configuration. The weight member 42 is sandwiched between two opposite side arms 431 and 432 of the U-shaped structure, and further the weight member 42 and the buffer member 43 are integrally inserted or snapped into the receiving cavity 411 of the locking member 41. It can be understood that the weight member 42 and the side wall of the receiving cavity 411 and the side arms 431 and 432 of the buffer member 43 apply clamping force to firmly hold the weight member 42 and the buffer member 43 in the receiving cavity 411.

Preferably, the outer side surfaces of the side arms 431 and 432 of the buffer 43 are provided with a projection 433. Accordingly, a pair of opposite side walls of the receiving cavity 411 of the locking member 41 is provided with catching grooves 412. In the process of inserting the buffer member 43 into the accommodating cavity 411, the projection 433 is clamped into the corresponding clamping groove 412, so as to further improve the installation firmness of the weight member 42 and the buffer member 43. It is further preferable that the size of the projection 433 in a natural state is larger than that of the card slot 412, and the projection 433 has a cavity. The cavity allows the projection 433 to elastically deform better to accommodate the size of the slot 412. And the projection 433 in the slot 412 has a tendency of elastic recovery, so that the acting force between the projection 433 and the slot 412 is increased, and the firm installation is further maintained.

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