The reset mechanism and the circuit control method will be described in detail in the following of this specification with reference to the accompanying drawings.

When a user cooks with the air fryer, the user first needs to push the fry vat of the air fryer into the cavity. At this time, the rib (not shown) on the wall surface of the air fryer, which is in contact with the horizontal lower surface of the fixing bracket guide groove 54, is pushed into the fixing bracket guide groove 54 from below, thereby pushing the push rod 3 installed in the fixing bracket guide groove 54 to move upward, and simultaneously, the return spring 4 sleeved on the push rod 3 is compressed due to the pushing force. At this time, the push rod trigger surface 34 on the push rod 3 will touch the micro switch 2 due to being pushed upwards, and apply a certain pressure to the micro switch 2, so as to conduct the control circuit inside the micro switch 2, so that the air fryer is in a ready state, and the user can start cooking instantly.

The user draws the air fryer pot out of the cavity after cooking. At this time, the rib (not shown) on the wall surface of the air fryer, which is in contact with the horizontal lower surface of the fixing bracket guide groove 54, is gradually withdrawn from the fixing bracket guide groove 54, the return spring 4 is gradually restored to the original length due to the disappearance of the pushing force, and the push rod 3 is displaced downward by the elastic force of the return spring 4. At this time, the push rod trigger surface 34 on the push rod 3 will be separated from the microswitch 2, thereby disconnecting the control circuit therein and rendering the air fryer inoperative.

Please refer to fig. 2 again. From the microswitch configuration shown in fig. 1, it will be appreciated by those skilled in the art that the on and off modes of the control circuit can be achieved by combining electrodes with switch contacts. Specifically, as shown in fig. 2, the microswitch 2 is provided with a microswitch contact 25 on one side thereof and three electrodes on a wall surface thereof, and for convenience of description, these three electrodes are referred to as a first microswitch electrode 21, a second microswitch electrode 22 and a third microswitch electrode 23, respectively.

Therefore, further than in fig. 1, when the frying pan of the air fryer is pushed into the cavity, the push rod triggering surface 34 will be pushed upwards to fully contact the micro switch contact 25 and exert a certain pressure on the micro switch contact 25, so that the micro switch first electrode 21 in the micro switch 2 is conducted with the micro switch third electrode 23, and the control circuit is in the working mode; when the fry vat of the air fryer is pulled out of the cavity, the push rod trigger surface 34 will displace downward and separate from the microswitch contact 25, and the pressure originally applied to the microswitch contact 25 will also disappear, causing the microswitch first electrode 21 to be disconnected from the microswitch third electrode 23, and the microswitch first electrode 21 to be connected to the microswitch second electrode 22, at which point the control circuit stops working.

Referring to fig. 3a and 3b, a front view and a side view of a push rod of a slide rod type micro-gap switch structure according to the present invention are shown.

As will be appreciated by those skilled in the art, to further optimize the installation manner between the push rod 3 and the fixed base 5, the push rod 3 may be provided with a segmented structure and some limiting structures may be provided on the fixed base 5. Specifically, as shown in fig. 3b, the pushrod 3 is composed of a pushrod triggering surface 34, a pushrod first end 31, a pushrod boss 32, and a pushrod second end 33, which are connected together in sequence. Referring to fig. 2, fig. 4a and fig. 4b, a push rod limiting groove 51 with a downward opening is disposed on the upper surface of the fixing base 5, a fixing bracket guiding groove 54 with an upward opening is disposed on the lower surface of the fixing base 5, and the push rod limiting groove 51 is communicated with the fixing bracket guiding groove 54.

During assembly, the push rod 3 needs to be pushed downward into an opening formed by the penetration of the push rod limiting groove 51 and the fixed bracket guide groove 54. At this time, the push rod second end 33 on the push rod 3 will eventually be pushed into the space formed by the fixing bracket guide groove 54 on the fixing bracket 5 such that the lower surface of the push rod second end 33 is flush with the lower surface of the fixing bracket guide groove 54. Meanwhile, the pushrod boss 32 on the pushrod 3 is placed in the pushrod limiting groove 51 such that the lower surface of the pushrod boss 32 and the upper surface of the pushrod limiting groove 51 contact each other and the pushrod boss 32 can be movably taken. In addition, the fixed bracket guide groove 54 also has a guiding function, and can guide the push rod 3 to always keep vertical up-and-down movement without deviation in the pushed process, so that the accuracy and the reliability of the contact between the push rod trigger surface 34 on the push rod 3 and the microswitch 2 are also ensured.

Referring to fig. 5a and 5b, a perspective view and a further perspective view of a vertical switch bracket 1 in a sliding-bar-type micro-switch structure according to the present invention are shown respectively.

Those skilled in the art can appreciate that, in order to further optimize the installation manner between the push rod 3, the return spring 4 and the vertical switch bracket 1, some limiting structures can be arranged on the vertical switch bracket 1. As shown in fig. 5a and 5b, the bottom of the vertical switch bracket 1 is provided with a spring-limiting groove 16 penetrating through the bottom, and a push-rod positioning rib 14 protruding upward is further provided on the upper surface of the bottom of the vertical switch bracket 1 at a position close to the spring-limiting groove 16.

After the assembly is completed, the push rod positioning rib 14 is located around the push rod first end 31 and plays a certain supporting role for the push rod first end 31, so that the push rod 3 is guaranteed to keep vertical up-and-down movement in the using process, the left-and-right swinging is avoided, and the accuracy of the contact between the push rod trigger surface 34 on the push rod 3 and the micro switch 2 is also guaranteed. Meanwhile, the return spring 4 fitted over the push rod 3 is fitted in the spring stopper groove 16. It should be understood that the length of the return spring 4 is longer than the distance between the lower bottom surface of the spring limiting groove 16 and the upper surface of the push rod limiting groove 51, so that the push rod 3 is compressed and deformed by pushing and is further pushed to move vertically during pushing.

Another aspect of the present invention relates to an air fryer using the slide bar type micro-gap switch structure. Wherein, the air fryer is provided with any sliding type microswitch structure.

Referring to fig. 6, it shows a perspective view of an air fryer having the slide bar type micro-gap switch structure according to the present invention. As shown in FIG. 6, the slider-type microswitch configuration is mounted on the body of the air fryer.

When the frying barrel of the air fryer is pushed into the cavity, the convex rib (not shown in the figure) on the wall surface of the air fryer pushes the push rod 3 to move upwards, and the return spring 4 sleeved on the push rod 3 is compressed due to the pushing force. At this time, the push rod 3 will touch the micro switch 2 and conduct the control circuit inside the micro switch 2, so that the user can start cooking by using the air fryer.

When the air fryer is drawn out of the cavity, the ribs (not shown) on the wall surface of the air fryer do not press the return spring 4 any more, the return spring 4 gradually recovers to the original uncompressed state due to the pressure loss, and the push rod 3 is pushed to displace downwards. At this time, the push rod 3 will be separated from the micro switch 2 to break the control circuit inside.

The embodiments disclosed in the present application are described above, but the descriptions are only for the convenience of understanding the present application and are not intended to limit the present application. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims.
