The manual operation board 5 includes parallel arrangement's splint to 10, the one end of linkage board 6 is located between splint to 10, the other end meets with the activity of the board 4 that resets, splint to 10's setting, be used for transmitting power to linkage board 6, no matter the manual operation board 5 is clockwise rotation or anticlockwise rotation, the homoenergetic drives the motion of linkage board 6, evaporate and be provided with first connecting rod 11 in the egg ware body 1, second connecting rod 12, the manual operation board 5, linkage board 6 corresponds the rotation and connects on first connecting rod 11, second connecting rod 12, first connecting rod 11, second connecting rod 12 are fixed connection in evaporating egg ware body 1, manual operation board 5 and linkage board 6 all set up the form of bending, help coordinating the linkage relation between manual operation board 5 itself, linkage board 6 itself, push rod 3 and the board 4 that resets.

The temperature controller 2 is internally provided with a fixed contact wiring board 13, a movable contact frame body 14 and an action element 15, the action element 15 is formed by overlapping a bimetallic disc and a conical spring sheet, the bimetallic disc is positioned at the inner side, the conical spring sheet is positioned at one side close to a linkage rod, the fixed contact 16 is arranged on the fixed contact wiring board 13, a movable contact 17 is arranged on the movable contact frame body 14, the fixed contact 16 corresponds to the movable contact 17, the action element 15 is connected with one end of the linkage rod 19, the other end of the linkage rod 19 is connected with the movable contact frame body 14, the push rod 3 is movably connected in the temperature controller 2, a stroke stop 18 is arranged below the push rod 3, the stroke stop 18 has the function of limiting the formation of the push rod 3, the push rod 3 is locked in the stroke stop 18 after being pushed inwards and can not be separated by self, the stroke stop 18 generally has stronger rigidity and can bear the reciprocating motion of the push rod 3 without deformation, the bimetallic disc, the conical spring plate and the travel stop 18 which form the actuating element 15 are the prior art of the temperature controller 2, and are not described herein in detail; the linkage rod 19 and the push rod 3 are arranged in a cylindrical shape, the axes of the linkage rod 19 and the push rod 3 are positioned on the same straight line, namely the linkage rod 19 and the push rod 3 are connected in a straight line, and the design is favorable for improving the interaction force between the linkage rod 19 and the push rod 3. The lower extreme of restoring plate 4 is connected on interlock pole 19 to the seesaw of interlock pole 19 can drive the rotation a little of restoring plate 4, and the upper end outwards extends outside temperature controller 2, and the slope overlap joint is in the top of linkage plate 6, helps the power transmission of linkage plate 6 to restoring plate 4 in.

The working principle of the manual switch structure is that, by taking fig. 3 to 5 as an example, when heating is needed, the manual operating plate 5 is manually pressed, the manual operating plate 5 rotates clockwise with the first connecting rod 11 as a base point, the block 7 on the manual operating plate 5 pushes the push rod 3, the inner end of the push rod 3 pushes the surface of the movable contact frame 14, which is provided with the movable contact 17, so that the movable contact 17 is connected with the fixed contact 16, and the circuit is connected to heat; at the same time, the push rod 3 will also push into the linkage rod 19, so as to flatten the conical spring sheet in the action element 15, and the stroke stop 18 will limit the push rod 3 not to move; when the linkage rod 19 moves inwards, the reset plate 4 is driven to rotate clockwise, namely, the linkage plate 6 is pressed, and when the manual operation plate 5 rotates clockwise by taking the first linkage rod 11 as a base point, the clamping plate pair 10 tilts upwards to drive the linkage plate 6 to rotate anticlockwise, namely, one end of the linkage plate 6 close to the reset plate 4 rotates downwards, so that the clockwise rotation of the reset plate 4 cannot be influenced; when the heating temperature reaches the action temperature, the bimetal disc is heated and deformed to a certain degree to generate a snap action, the conical spring sheet is pushed by the bimetal disc to reversely bounce, the linkage rod 19 is pushed outwards, the linkage rod 19 pushes the side, provided with the moving contact 17, of the moving contact frame body 14 and the push rod 3 outwards, the moving contact 17 is separated from the fixed contact 16, the circuit is disconnected, the push rod 3 is reset, the manual operation plate 5, the reset plate 4 and the linkage plate 6 are all reversely rotated and return to the state shown in figure 3, when the temperature is reduced, the bimetal disc is restored to the original state, but the conical spring sheet does not have the automatic reset capability, so the conical spring sheet cannot be reset, if the manual operation plate 5 needs to be pressed down again, the linkage rod 19 is pushed inwards through external force to crush the conical spring sheet, and the circuit cannot be connected for heating, the safety is high. In addition, if the manual operation plate 5 needs to be heated in an emergency stop after being pressed down, the manual operation plate 5 can be lifted manually, the manual operation plate 5 rotates anticlockwise by taking the first connecting rod 11 as a base point, the linkage plate 6 is driven to rotate clockwise by taking the second connecting rod 12 as a base point, so that the inner end of the linkage plate 6 can lift the reset plate 4 to rotate anticlockwise, the lower end of the reset plate 4 can drive the linkage rod 19 to push outwards, the purpose of breaking a circuit can be achieved, and the structure is ingenious.

Finally, it should be noted that: although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
