Fig. 1 shows an air electric pressure cooker according to an embodiment of the present invention. As shown in fig. 1, the air electric pressure cooker comprises a cooker body assembly 1 and a cooker cover assembly 2. The pot cover component 2 is connected with the pot body component 1 through a rotating shaft 11. In fig. 1, the pressure lid 9 has not yet been mounted to the lid assembly 2, and the air pressure cooker may now be used to perform the air fryer function. When the pressure cooker function is required for stew cooking, the pressure cover 9 can be mounted to the lid assembly 2. When the pressure cover 9 is installed on the pot cover assembly 2, the pressing block 10 arranged on the pressure cover 9 pushes the switch pushing rod 7 in the switch assembly, so that the switch pushing rod 7 triggers the switch 5, and the opening and closing state of the switch 5 is changed. The switch 5 is electrically connected with a control circuit in the air electric pressure cooker so that the control circuit can sense whether the pressure cover 9 is mounted in place by sensing a state change of the switch 5. The control circuit is then able to automatically confirm whether or not the stewing function of the pressure cooker is performed.

Fig. 2 to 9 show the structures of respective components in the pot cover assembly 2 according to the embodiment of the present invention. The pot lid assembly 2 according to the embodiment of the present invention will be described in detail with reference to fig. 2 to 9.

Figures 2 and 3 show a schematic view of the motor housing in the lid assembly. Figure 4 is a schematic view of a pressure cap in the lid assembly. In the present embodiment, the lid assembly includes a motor cover 3 and a pressure lid 9 detachably mounted under the motor cover 3. The pressure cover 9 is provided with a pressing block 10. The motor cover 3 is provided with a switch component. The switch assembly comprises a switch fixing frame 6, a switch push rod 7 and a switch 5, wherein the switch push rod and the switch are installed on the switch fixing frame 6. When the pressure cover 9 is installed below the motor cover 3, the pressing piece 10 pushes the switch push lever 7 to move from the initial position to the trigger position. In the trigger position, the switch pusher 7 actuates the switch 5 to change the state of the switch 5. Therefore, the control circuit electrically connected to the switch 5 can detect the mounting state of the pressure cover by detecting the state change of the switch.

Fig. 4 shows the structure of the pressure cover 9. A press block 10 is fixedly arranged on the pressure cover 9. The compact 10 includes a compact guide surface 10a and a compact pushing surface 10 b. Fig. 7 shows the structure of the switch pusher lever 7. The switch push rod 7 includes a switch push rod push surface 7a, a switch push rod guide surface 7b, a first spring fulcrum 7c, a switch push rod upper plane 7d, a switch push rod lower plane 7e, and a stopper 7 f. As shown in fig. 8, the switch 5 includes a switch contact 5a, an alignment hole 5b, and a first switch electrode 5c and a second switch electrode 5 d. When the pressure cover 9 is installed below the motor cover 3, the press block guide surface 10a and the press block pushing surface 10b are sequentially in sliding contact with the switch push rod pushing surface 7a, so that the switch push rod 7 is forced to move from the initial position to the trigger position, the switch push rod guide surface 7b with the inclined surface moves rightwards, and the switch contact 5a is triggered (the switch contact 5a is deformed), and the state of the switch 5 is changed. The press piece guide surface 10a has a guide function such that the switch urging lever urging surface 7a can move smoothly and transition to a state of contact with the press piece urging surface 10 b. The pressing block pushing surface 10b is matched with the switch pushing rod pushing surface 7a, and the pressure cover 9 can reciprocate in a certain range. When the switch-pushing-lever guide surface 7b touches the switch contact 5a, the connection state between the first switch electrode 5c and the second switch electrode 5d may be changed from closed to open, or from open to closed. The first switch electrode 5c and the second switch electrode 5d can be connected with a control circuit of the air electric pressure cooker. The control circuit can thus determine whether the pressure cover has been mounted in place by sensing the change in the open-closed state of the first and second switching electrodes 5c and 5 d.

Fig. 6 shows the structure of the switch holder 6. In the present embodiment, the switch pusher 7, the switch 5, and the spring 8 are installed in the switch holder 6, and the switch 5 is located above the switch pusher 7 and the spring 8. The switch fixing frame 6 comprises a screw hole 6a, a second spring fulcrum 6b, a switch fixing column 6c, an upper buckle 6d, a lower buckle 6e, a switch buckle 6f, a switch fixing frame upper end surface 6g and a switch push rod supporting surface 6 h. The switch 5 may be fixed in the switch fixing frame 6 by a switch fixing post 6c and a switch catch 6 f. Specifically, when the switch 5 is fixed in the switch fixing frame 6, the switch fixing post 6c is inserted into the switch positioning hole 5b, thereby ensuring accurate positioning of the switch 5 and preventing shaking during use. The switch 5 is laterally embedded in the switch catch 6f so that the switch 5 is confined in the switch holder 6. The switch push rod 7 is installed between the upper catch 6d and the lower catch 6e of the switch holder 6, and is slidable on the switch push rod support surface 6 h. Specifically, the upper plane 7d of the switch push rod is located below the upper buckle 6d, and the lower plane 7e of the switch push rod is located below the lower buckle. The width W2 between the upper catch 6d and the lower catch 6e is smaller than the width W1 of the switch push rod 7, so that the switch push rod 7 must elastically deform the upper catch 6d and the lower catch 6e to both sides to be inserted into the space defined below the upper catch 6d and the lower catch 6 e. Therefore, the switch-pushing lever 7 is defined in a space defined below the upper catch 6d and the lower catch 6e, and can slide on the switch-pushing-lever support surface 6h with respect to the upper catch 6d and the lower catch 6 e.

A spring 8 in a compressed state is arranged between a first spring fulcrum 7c at the end part of the switch pushing rod 7 and a second spring fulcrum 6b on the switch fixing frame 6. Specifically, one end of the spring 8 is fixed to the first spring fulcrum 7c, and the other end of the spring 8 is fixed to the second spring fulcrum 6 b. The inner diameters of the first spring fulcrum 7c and the second spring fulcrum 6b can be set to be smaller than the inner diameter of the spring 8, so that the two ends of the spring 8 can be sleeved on the first spring fulcrum 7c and the second spring fulcrum 6b respectively. In the initial position of the switch-pushing lever 7, the distance between the first spring fulcrum 7c at the end of the switch-pushing lever 7 and the second spring fulcrum 6b on the switch-fixing bracket 6 is smaller than the length of the spring 8, so that the spring 8 is in a compressed state. The spring 8 in a compressed state generates an elastic force that keeps the switch push lever 7 at the initial position. When the switch push lever 7 is moved to the trigger position against the elastic force of the spring 8 by the driving of the pressing piece 10, the spring 8 is further compressed and generates an elastic force that returns the switch push lever 7 to the initial position. Therefore, when the pressure cover 9 is detached from below the motor cover 3, the pressing piece 10 no longer abuts against the switch pushing lever pushing surface 7 a. In other words, the switch pusher 7 is no longer blocked by the pressure piece 10 and can return to the initial position under the spring force of the spring 8. In the initial position, the stopper 7f of the switch-pushing lever 7 abuts against the edge of the switch-pushing-lever seating surface 6h, thereby defining the range of movement of the switch-pushing lever 7. In the initial position, the switch pusher guide surface 7b is not in contact with the switch contact 5a of the switch 5.

Fig. 9 shows the structure of the switch bracket presser plate 4. The switch bracket pressure plate 4 includes a first fixing hole 4a, a second fixing hole 4b, and a switch bracket pressure plate pressing surface 4 c. The switch bracket pressing plate 4 is fixed on the motor cover through screws of the first fixing hole 4a and the second fixing hole 4 b. The switch bracket pressure plate 4 is pressed on the switch fixing frame 6, so that the switch fixing frame 6 is tightly attached to the motor cover 3. Specifically, the pressing surface 4c of the switch bracket pressing plate is pressed on the upper end surface 6g of the switch fixing frame 6, so that the lower end of the switch fixing frame 6 is tightly attached to the motor cover 3. Meanwhile, the screw penetrates through the screw hole 6a of the switch fixing frame 6 to further fix the switch fixing frame 6 on the motor cover 3.

So far, some specific embodiments of the present invention have been described in detail by way of examples, but it should be understood by those skilled in the art that the above examples are only for illustrative purposes and are not intended to limit the scope of the present invention. It will be understood by those skilled in the art that various changes may be made in the above embodiments or equivalents may be substituted for elements thereof without departing from the scope and spirit of the utility model.
