For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] For the lid opening structure of the air heat transfer rice cooker, please refer to Figure 1 The air heat transfer rice cooker comprises: a pot cover 110 and a pot body 120 , the pot cover 110 is installed on the pot body 120 in a flip-cover style, and an opening structure is arranged between the pot cover 110 and the pot body 120 .

[0036] See also Figure 1-7 As shown, the cover opening structure includes: a button 200 , a locking tongue 300 , a first spring 410 and a second spring 420 .

[0037] The button 200 is installed on the pot cover 110 and exposed on the upper surface of the pot cover 110. The user can apply force to trigger and push the button 200 to move vertically downward;

[0038] The locking tongue 300 is assembled on the pot cover 110 and the tongue portion 310 of the locking tongue 300 is matched with the locking groove 121 of the pot body 120;

[0039] The first spring 410 provides elastic force in the longitudinal direction of the key 200;

[0040] The second spring 420 provides elastic force in the lateral direction of the locking tongue 300;

[0041] The locking tongue 300 is rotatably mounted on the pot cover 110 around a horizontal axis;

[0042] The button 200 moves vertically downward to trigger the lock tongue 300 to move, and the lock tongue 300 rotates around the horizontal axis to separate the tongue portion 310 from the lock slot 121;

[0043] When the pot cover 110 and the pot body 120 are closed, the tongue 310 of the locking tongue 300 is tightly buckled in the locking groove 121, and the second spring 420 provides a force for the tongue 310 to be tightly buckled in the locking groove 121; the first spring 410 provides an upward elastic force for the button 200;

[0044] When the lid needs to be opened, the button 200 is pressed down, the first spring 410 is compressed, the button 200 pushes the locking tongue 300 to rotate, and the tongue 310 leaves the locking groove 121, so that the pot lid 110 is opened;

[0045] like Figure 2 As shown, the pot cover 110 is rotatably connected to the pot body 120, and a torsion spring is provided at the connection. After the tongue 310 leaves the locking groove 121, the pot cover 110 is automatically rotated and opened by the elastic force of the torsion spring.

[0046] After the force applied to the button 200 disappears, the button 200 automatically returns to its original position under the elastic force of the first spring 410 , and the lock tongue 300 automatically returns to its original position under the elastic force of the second spring 420 ;

[0047] like Figure 3 As shown, when the button 200 is pressed down, the tongue 310 is pushed to rotate clockwise and the tongue 310 leaves the lock slot 121 ; when the force applied to the button 200 is released, the tongue 310 rotates counterclockwise and returns to its original position under the elastic force of the second spring 420 .

[0048] In one embodiment, if Figure 7As shown, the button 200 is provided with a downwardly extending card foot 210 and a downwardly protruding trigger top column 220, and the trigger top column 220 is provided with the trigger inclined surface 201; when the button 200 moves vertically downward, the trigger inclined surface 201 pushes the lock tongue 300 to rotate around the horizontal axis 320.

[0049] In one embodiment, if Figure 6 As shown, the locking tongue 300 includes: a tongue portion 310 , a horizontal shaft portion 320 and a trigger portion 330 . The horizontal shaft portion 320 is pivotally connected to the pot cover 110 ; the trigger portion 330 corresponds to the trigger slope 201 , and the tongue portion 310 cooperates with the locking groove 121 of the pot body 120 .

[0050] In one embodiment, if Figure 4 As shown, the pot cover 110 is provided with a mounting hole 111 for assembling the button 200, and a through hole 112 is correspondingly provided in the mounting hole 111 through which the trigger top column 220 extends downward; the button 200 is snap-fitted into the mounting hole 111, and the trigger top column 220 passes through the through hole 112 to trigger the lock tongue 300.

[0051] Furthermore, one end of the first spring 410 is supported on the inner bottom surface of the mounting hole 111, and the other end is supported on the button 200, providing elastic force in the longitudinal direction of the button 200, that is, providing an upward elastic force for the button 200;

[0052] The button 200 can move vertically in the installation hole 111. Since the foot 210 is installed in a snap-fit ​​manner and extends downward through the installation hole 111, it cannot be separated from the installation hole 111 upward, so that the button 200 can move up and down.

[0053] In one embodiment, a limiting groove 331 is provided on the front side of the trigger portion 330 of the locking tongue 300, one end of the second spring 420 is supported on the limiting groove 331, and the other end is supported on the inner wall of the pot cover 110, and the second spring 420 is laterally arranged to provide lateral elastic force to the locking tongue 300, so that the tongue portion 310 of the locking tongue 300 is tightly snapped into the locking groove 121, and the locking groove 121 is provided on the outer shell of the pot body 120.

[0054] After the force applied to the key 200 disappears, Figure 3 As shown, the horizontal shaft portion 320 is disposed in the middle of the locking tongue 300 , and the second spring 420 provides a leftward elastic force to the trigger portion 330 , so that the tongue portion 310 is buckled to the right in the locking slot 121 .

[0055] The cover opening structure of the utility model has fewer parts and components, is easy to install, convenient to use, simple and effective.

[0056] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
