The elastic piece has elastic performance, and the elastic piece can change the position along with the hook rod during the movement of the hook rod so as to generate or improve the elastic force of the elastic piece. When a user operates the hook rod, the hook rod is not operated in place, for example, in the process of switching the hook rod from the locking position to the unlocking position, the user leaves the hook rod without reaching the unlocking position, so that the hook rod stays between the locking position and the unlocking position, the hook rod continues to move by the elastic force of the elastic piece until the hook rod reaches the unlocking position, so that the cover body and the appliance body of the cooking appliance are prevented from being in a half-locking state, the cover body cannot be normally opened in the process of opening the cover, and in the process of closing the cover, a locking device used for locking the appliance body on the cover body collides with the appliance body of the cooking appliance, so that the locking device and the appliance body are collided or damaged.

Further, in the process that the hook lever is switched from the locking position to the unlocking position, the maximum length of the elastic part is L3, the length of the elastic part is L1 when the hook lever is located at the locking position, the length of the elastic part is L2 when the hook lever is located at the unlocking position, L1 is less than L3, and L2 is less than L3. The hook rod is switched from the locking position to the unlocking position or from the unlocking position to the locking position, and the length of the elastic piece is firstly lengthened and then shortened. When the length of the elastic piece changes from L1 to L3 and from L3 to L1, the elastic piece has a tendency of restoring the length to L1, and at the moment, if a user loosens the hook rod, the elastic piece can drive the hook rod to move to the locking position. When the length of the elastic piece changes from L2 to L3 and from L3 to L2, the elastic piece has a tendency of restoring the length to L2, and at the moment, if a user loosens the hook rod, the elastic piece can drive the hook rod to move to an unlocking position. When the hook rod is in the locking position, if a user touches the hook rod by mistake, the elastic piece can quickly reset the hook rod so as to avoid the condition of opening the cover; when the hook rod is in the unlocking position, if a user mistakenly touches the hook rod elastic piece, the hook rod can be quickly reset so as to avoid the pot cover being in a half-locking state. When the length of the elastic member is L3, the hook lever is randomly turned in the direction of the lock position or the unlock position under the combined action of various conditions such as the elastic force of the elastic member, the weight of the hook lever, the inertia of the hook lever movement, and the assembly and manufacturing errors, and cannot be held at the position of the length L3 of the elastic member.

Further, the length L1 of the elastic member when the hook lever is located at the locking position is equal to the length L2 of the elastic member when the hook lever is located at the locking position. Because the elastic force of the elastic piece can keep the hook rod at the locking position or the unlocking position, the length of the elastic piece can keep L1 or L2 for a long time, and L1 and L2 are equal, namely the length of the elastic piece cannot change in most of time, the whole action force value of the elastic piece is ensured not to change greatly, and the service life is longer.

Furthermore, the length of the elastic part in a natural state is L4, L4 is less than L1, and L4 is less than L2. When the hook rod is located at the locking position or the unlocking position, the elastic piece always has elastic force applied to the hook rod so as to keep the current position of the hook rod, improve the stability of the hook rod and avoid the hook rod from turning over due to mistaken touch of a user.

While the present invention has been described with reference to certain embodiments, it will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details.

Referring to fig. 1 to 7, the embodiment of the present invention discloses a lid opening structure of a cooking appliance, including a rotatable hook lever 200 and an elastic member 300 connecting the hook lever 200, the hook lever 200 has a locking position and an unlocking position on the cooking appliance, the hook lever 200 is switched between the locking position and the unlocking position to lock or unlock the cooking appliance, one end of the elastic member 300 is connected to the cooking appliance, the other end of the elastic member 300 is connected to the hook lever 200, and the elastic member 300 drives the hook lever 200 to move to one of the locking position and the unlocking position when the hook lever 200 is located between the locking position and the unlocking position.

The cooking appliance is generally a pressure cooker, and includes an appliance body and a cover body 100, the cover body 100 is provided with a locking structure, a hook rod 200 is rotatably mounted on the cover body 100, and the rotating hook rod 200 can drive the locking structure to act, so as to firmly fix a pot cover on a pot body of the cooking appliance, and to keep a sealing state against a cooking container in the appliance body, so as to maintain a high-temperature and high-pressure state in the cooking container. Usually, the locking mechanism is a caliper structure or a rotatable pot tooth, but in any structure, once the locking mechanism is not moved in place in the operation process, the locking mechanism and the appliance body are in a half-locking state, namely, the part of the locking mechanism and the pot body are in a locking state, the locking strength is insufficient, and the opening of the cover is influenced.

The utility model discloses a structure of uncapping disposes the hooked pole 200 on the lid 100, switches the position of hooked pole 200 through operating the hooked pole 200 to can make cooking utensil locking or unblock, force application part can keep the hooked pole 200 at latched position and keep the lock-out state between lid 100 and the utensil body, or keep the hooked pole 200 at the unlock position and keep the unlock state between lid 100 and the utensil body.

The elastic member 300 has an elastic property, and the elastic member 300 can be changed in position along with the hook lever 200 during the movement of the hook lever 200 to generate or enhance its own elastic force. When a user does not operate the hook lever 200 in place when operating the hook lever 200, for example, in the process of switching the hook lever 200 from the locking position to the unlocking position, the user's hand leaves the hook lever 200 before the hook lever 200 reaches the unlocking position, so that the hook lever 200 stays between the locking position and the unlocking position, the elastic force of the elastic member 300 enables the hook lever 200 to continue to move until the hook lever 200 reaches one of the locking position and the unlocking position, so as to avoid the cover body 100 and the appliance body being in a half-locking state, prevent the cover body 100 from being normally opened in the cover opening process, and in the cover closing process, the locking device collides with the appliance body, so that the locking device and the appliance body are collided or damaged before. In addition, the elastic member 300 may also be used to assist the user, when the user operates the hook lever 200, the elastic force generated by the elastic member 300 has a driving effect on the hook lever 200, so that the hook lever 200 can be more easily switched to the locking position or the unlocking position, and the user does not need to completely move the hook lever 200 in place during the operation, which is convenient for the user to operate.

The locking mechanism in the pot cover in the application is a caliper device and comprises a sliding block and a caliper, the hook rod 200 can be vertically overturned relative to the cover body 100, when the hook rod 200 is upwards overturned relative to the cover body 100, the hook rod 200 is switched to an unlocking position from a locking position, otherwise, the hook rod 200 is switched to the locking position from the unlocking position, the overturning action of the hook rod 200 can drive the sliding block to slide, and therefore the caliper can be locked or unlocked with the appliance body.

Referring to fig. 2 to 4, in an embodiment of the present invention, based on the above embodiment, the elastic member 300 can drive the hook lever 200 to the locking position and can drive the hook lever 200 to the unlocking position.

Specifically, the method comprises the following steps: the hook lever 200 is provided with a first rotating shaft 210 rotatably engaged with the cover 100, the first rotating shaft 210 is closer to the locking mechanism than the position where the elastic member 300 is hinged to the cover 100, the length of the elastic member 300 is L1 when the hook lever 200 is located at the locking position, the length of the elastic member 300 is L2 when the hook lever 200 is located at the unlocking position, the maximum length of the elastic member 300 is L3, L1 < L3, and L2 < L3. When the length of the elastic member 300 changes from L1 to L3, and from L3 to L1, the elastic member 300 tends to restore the length to L1, and at this time, if the user releases the hook lever 200, the elastic member 300 can drive the hook lever 200 to move to the locking position. When the length of the elastic member 300 changes from L2 to L3, and from L3 to L2, the elastic member 300 tends to restore the length to L2, and at this time, if the user releases the hook lever 200, the elastic member 300 can drive the hook lever 200 to move to the unlocking position.

When the hook lever 200 is in the locking position, if the user touches the hook lever 200 by mistake, the elastic member 300 can quickly reset the hook lever 200 to avoid the situation of opening the cover; when the hook lever 200 is in the unlocking position, if the user accidentally touches the elastic member 300 of the hook lever 200, the hook lever 200 can be rapidly reset to prevent the lid from being in the half-locked state.

The elastic member 300 is preferably a tension spring, which generates a large elastic force when being extended, one end of the tension spring is hooked on the cooking appliance through a first hook, and the other end of the tension spring is hooked on the hook lever 200 through a second hook, and as the hook lever 200 rotates, both ends of the tension spring can rotate relative to the cooking appliance and the hook lever 200, respectively, so as to reduce the torsion force applied to the tension spring. Of course, if the elastic member selects the compression spring, and the position of the rotating shaft is set at the rear side of the position where the elastic member is hinged to the cover body, the compression spring is compressed along with the turning of the hook rod, and an elastic acting force is also generated, but the compression spring is easy to form change in the radial direction, so that the hook rod cannot be driven to move due to too small elastic force.

As shown in fig. 3, the positions where the first rotating shaft 210 and the elastic member 300 are hinged to the cover 100 are on the same horizontal line, when the length of the elastic member 300 is L3, the elastic member 300 is located in the horizontal direction, and when the length of the elastic member 300 is less than L3, the end of the elastic member 300 hinged to the hook rod 200 is higher or lower than the first rotating shaft 210, at this time, the elastic member 300 has a tendency of shortening, and a component force in the horizontal direction and a component force in the vertical direction can be obtained by decomposing the elastic force of the elastic member 300, and the component force in the horizontal direction can drive the hook rod 200 to rotate to the locking position or the unlocking position. On the other hand, when the length of the elastic member 300 is L3, the hook lever 200 is randomly turned in the direction of the locking position or the unlocking position by the combined action of the elastic force of the elastic member 300, the weight of the hook lever 200, the motion inertia of the hook lever 200, and the assembly and manufacturing errors, and thus cannot be held at the position where the length of the elastic member 200 is L3.

As shown in fig. 5, in addition, the positions where the first rotating shaft 210 and the elastic member 300 are hinged to the cover body 100 may be located on different horizontal planes. When the length of the elastic member 300 is L3, the elastic member 300 is extended along a connecting line between the hinged position of the elastic member and the cooking utensil and the first rotating shaft 210, and the force component thereof has a vertical component and a horizontal component, and the two components cannot be kept equal under the combined action of the elastic force of the elastic member 300, the gravity of the hook rod 200, the motion inertia of the hook rod 200, and assembly and manufacturing errors, so that the hook rod 200 is driven to turn. When the elastic member 300 is extended in the horizontal direction or the vertical direction, the elastic direction of the elastic member 300 is a tangential direction of the first rotating shaft 210, and has an effect of driving the hook lever 200 to rotate, so that the hook lever 200 cannot stay at a position between the locking position and the unlocking position.

Referring to fig. 2 and 4, in an embodiment of the present invention, based on the above-described embodiment, the length L1 of the elastic member 300 when the hook lever 200 is located at the locking position is equal to the length L2 of the elastic member 300 when the hook lever 200 is located at the locking position. Since the elastic force of the elastic member 300 can maintain the hook lever 200 at the locking position or the unlocking position, the length of the elastic member 300 can maintain L1 or L2 for a long time, and L1 and L2 are equal, that is, the length of the elastic member 300 does not change in most of the time, so that the full-stroke force value of the elastic member 300 is ensured to be not changed greatly, and the service life is longer.

In an embodiment of the present invention, based on the above embodiment, the length of the elastic member in the natural state is L4, L4 < L1, and L4 < L2. When the hook rod is located at the locking position or the unlocking position, the elastic piece always has elastic force applied to the hook rod so as to keep the current position of the hook rod, improve the stability of the hook rod and avoid the hook rod from turning over due to mistaken touch of a user.
