When the temperature sensor is in working, the heating assembly at the bottom of the cup body is started or stopped by the electric control assembly according to the temperature value detected by the temperature sensor at the bottom of the cup body, namely when the electric control assembly is out of order, the first temperature sensing switch and the second temperature sensing switch can not act and are in a standby state. Once the problem appears in the automatically controlled subassembly, can not let it stop when heating element should stop, so the heating pipe will continue work, and the temperature of dish that generates heat will continuously rise, and when the temperature of dish that generates heat rose to the temperature sensing threshold value of first temperature-sensing switch, first temperature-sensing switch will move the route of cutting off first electric conductor for the heating pipe outage avoids taking place danger. If the electric control assembly and the first temperature sensing switch are both in failure, the second temperature sensing switch is arranged, the principle of the second temperature sensing switch is similar to that of the first temperature sensing switch, when the temperature of the heating disc rises to the temperature sensing threshold value of the second temperature sensing switch, the second temperature sensing switch can act to cut off the passage of the second electric conductor, so that the heating pipe is powered off, and danger is avoided.

Like this, when the dish temperature that generates heat rises to the temperature sensing threshold value of first temperature switch, first temperature switch will move and push away first electrically conductive shell fragment, make first contact and second contact part, then the route of first electric conductor has just been broken off, first electrically conductive shell fragment has taken place to warp this moment, be in the energy storage state, when the dish temperature that generates heat reduces to the temperature sensing threshold value that is less than first temperature switch, first temperature switch will automatic re-setting, first electrically conductive shell fragment will rebound under its self elastic force effect, make first contact and second contact once more, then the route of first electric conductor has just switched on again.

Furthermore, the first temperature sensing switch comprises a first connecting column and a self-resetting temperature sensing piece, one end of the first connecting column is fixedly connected with the position, close to the second contact, of the first conductive elastic piece, the self-resetting temperature sensing piece is fixed to the first end face of the shell, the position, corresponding to the first connecting column, of the first end face of the shell is provided with a first concave position for bending and deforming the first deforming end, and the other end of the first connecting column extends out of the first concave position of the first end face and is opposite to the first deforming end of the self-resetting temperature sensing piece. When the temperature of the self-resetting temperature sensing piece is lower than the temperature sensing threshold value of the self-resetting temperature sensing piece, the first deformation end of the self-resetting temperature sensing piece faces one side, when the temperature rises to the temperature sensing threshold value of the self-resetting temperature sensing piece, the first deformation end of the self-resetting temperature sensing piece can bend and deform towards the opposite side, and when the temperature is reduced again, the first deformation end of the self-resetting temperature sensing piece can automatically reset. In the utility model, when the temperature of the self-resetting temperature sensing piece reaches the temperature sensing threshold value, the first deformation end of the self-resetting temperature sensing piece bends and deforms towards the side of the first concave position and extrudes the first connecting column, and the first conductive elastic piece is extruded and deformed through the first connecting column, so that the first contact and the second contact are separated; when the temperature is reduced to be lower than the temperature sensing threshold value again, the first deformation end of the first conductive elastic sheet deforms and resets towards the side opposite to the first concave position, and the first conductive elastic sheet resets under the action of the elastic force of the first conductive elastic sheet.

As a preferred scheme, the second temperature-sensing switch is a non-resettable temperature-sensing switch, the second conductor includes a second conductive metal sheet and a second conductive elastic sheet fixed on the inner wall of the housing, one end of the second conductive metal sheet and one end of the second conductive elastic sheet both extend out of the housing, the other end of the second conductive metal sheet and the other end of the second conductive elastic sheet are both disposed inside the housing, a third contact and a fourth contact are respectively disposed on the other end of the second conductive metal sheet and the other end of the second conductive elastic sheet, the second temperature-sensing switch is connected to a position of the second conductive elastic sheet close to the fourth contact, the second conductive elastic sheet is extruded and deformed to make the third contact and the fourth contact, and the second conductive elastic sheet is in an energy storage state. Like this, when the temperature of the dish that generates heat rises to the temperature sensing threshold value of second temperature-sensing switch, second temperature-sensing switch will loosen the electrically conductive shell fragment of second, the electrically conductive shell fragment of second pops open under its self elastic force effect for third contact and fourth contact separate, then the route of second electric conductor has just been broken off, the electrically conductive shell fragment of second takes place to warp this moment the back and is in natural state, it can not rebound again automatically under the effect of not having the external force and makes third contact and fourth contact, because second temperature-sensing switch is not resettable, so the route disconnection of second electric conductor just can not switch on automatically again.

Furthermore, the second temperature sensing switch is a cylindrical thermal link, one end of the cylindrical thermal link is fixedly connected with the second conductive elastic sheet at a position close to the fourth contact, and the other end of the cylindrical thermal link is fixedly connected with the first end face of the shell.

Furthermore, the second temperature sensing switch comprises a second connecting column and a non-self-resetting temperature sensing piece, one end of the second connecting column is fixedly connected with the position, close to the fourth contact, of the second conductive elastic piece, the non-self-resetting temperature sensing piece is fixed to the position, corresponding to the second connecting column, of the first end face of the shell, a second concave position for bending and deforming the second deformation end is arranged at the position, corresponding to the second deformation end of the non-self-resetting temperature sensing piece, of the first end face, and the other end of the second connecting column extends out of the second concave position of the first end face and is opposite to the second deformation end of the non-self-resetting temperature sensing piece. In this case, the structure of the second temperature sensitive switch is substantially the same as that of the first temperature sensitive switch, and the only difference is that the second temperature sensitive switch adopts the non-resettable temperature sensitive sheet, so that once the second temperature sensitive switch is actuated, the machine needs to be disassembled for maintenance, and the non-resettable temperature sensitive sheet is restored to the original position by applying an external force. For more convenient maintenance, a manual reset device can be arranged on the third temperature-sensitive switch, so that the third temperature-sensitive switch can be manually reset without disassembling the machine. The manual reset device has the following specific structure: the position that corresponds with the second spliced pole on the second terminal surface of casing is equipped with first through-hole, the ejector pin is worn to be equipped with in the activity in the first through-hole, ejector pin one end stretch into the casing inside and with on the second conductive elastic piece with the fixed position connection that the second spliced pole is connected, the ejector pin other end stretches out the outside certain length of casing. The ejector pin other end can set up stretch out to the broken wall machine bottom outside, like this, can be with the manual reset of third temperature-sensing switch in the broken wall machine bottom outside through pressing the ejector pin.

Furthermore, the temperature sensor is an NTC temperature sensing probe, a support frame is arranged on one side of the shell, which is close to the two poles of the heating pipe, and the NTC temperature sensing probe is fixed on the support frame. Therefore, the NTC temperature sensing probe is fixed by one temperature sensing safety control assembly without being separately fixed, and further, the parts at the bottom of the cup body are more convenient to install. The heating plate is provided with a through hole at a position corresponding to the NTC temperature sensing probe, and the NTC temperature sensing probe penetrates through the through hole and extends into the cup body. Therefore, the NTC temperature sensing probe can detect the temperature which is closer to the liquid in the cup body.

Therefore, three safety switches are equivalently arranged on the wall breaking machine, and the danger can be basically and completely avoided.

As shown in fig. 8, the first temperature-sensing switch 8 is a self-resettable temperature-sensing switch, the first conductor 6 includes a first conductive metal sheet 61 and a first conductive elastic sheet 62 fixed on the inner wall of the housing 5, one end of the first conductive metal sheet 61 and one end of the first conductive elastic sheet 62 both extend out of the housing 5, the other end of the first conductive metal sheet 61 and the other end of the first conductive elastic sheet 62 both are disposed inside the housing 5, the other end of the first conductive metal sheet 61 and the other end of the first conductive elastic sheet 62 are respectively provided with a first contact 10 and a second contact 11, the first contact 10 and the second contact 11 are in contact, the first conductive elastic sheet 62 is in a natural state, and the first temperature-sensing switch 8 and the first conductive elastic sheet 62 are connected at a position close to the second contact 11.

This embodiment is similar to embodiment 1, except that, as shown in fig. 10, the second temperature sensitive switch 9 is a manually resettable temperature sensitive switch, the second conductor 7 comprises a second conductive metal sheet 71 and a second conductive elastic sheet 72 fixed on the inner wall of the shell 5, one end of each of the second conductive metal sheet 71 and the second conductive elastic sheet 72 extends out of the housing 5, the other ends of the second conductive metal sheet 71 and the second conductive elastic sheet 72 are both arranged inside the shell 5, and the other ends of the second conductive metal sheet 71 and the second conductive elastic sheet 72 are respectively provided with a third contact 12 and a fourth contact 13, the third contact 12 is in contact with the fourth contact 13, the second conductive elastic sheet 72 is in a natural state, the second temperature-sensitive switch 9 is connected to the second conductive elastic sheet 72 at a position close to the fourth contact 13. Thus, when the temperature of the heating plate 3 rises to the temperature sensing threshold of the second temperature sensing switch 9, the second temperature sensing switch 9 will act to push the second conductive elastic sheet 72 open, so that the third contact 12 and the fourth contact 13 are separated, the path of the second conductor 7 is disconnected, and at this time, the second conductive elastic sheet 72 is deformed and is in an energy storage state; however, the second temperature-sensitive switch 9 can only be manually reset, and cannot be automatically reset, so when the temperature of the heat-generating plate 3 is reduced to be lower than the temperature-sensitive threshold of the second temperature-sensitive switch 9, the second temperature-sensitive switch 9 cannot be automatically reset, and an external force must be manually applied to reset the second temperature-sensitive switch 9, the second conductive elastic sheet 72 will rebound under the action of the elastic force of the second conductive elastic sheet 72, so that the third contact 12 and the fourth contact 13 are contacted again, and then the path of the second conductor 7 is turned on again.

As shown in fig. 10 and 11, the second temperature-sensitive switch 9 includes a second connection post 91 and a non-self-resetting temperature-sensitive sheet 92, one end of the second connection post 91 is fixedly connected to the second conductive elastic sheet 72 at a position close to the fourth contact 13, the non-self-resetting temperature-sensitive sheet 92 is fixed to a position on the first end surface 51 of the housing 5 corresponding to the second connection post 91, a second recess 512 for bending and deforming the second deformation end 921 is disposed on the first end surface 51 corresponding to the second deformation end 921 of the non-self-resetting temperature-sensitive sheet 92, and the other end of the second connection post 91 extends out of the second recess 512 of the first end surface 51 and faces the second deformation end 921 of the non-self-resetting temperature-sensitive sheet 92. In this case, the second temperature sensitive switch 9 has a structure substantially the same as that of the first temperature sensitive switch 8, and the only difference is that the second temperature sensitive switch 9 employs the non-resettable temperature sensitive sheet 92, so that once the second temperature sensitive switch 9 is actuated, the machine needs to be removed for maintenance, and the non-resettable temperature sensitive sheet 92 is returned to its original position by applying an external force. For more convenient maintenance, a manual reset device can be arranged on the third temperature-sensitive switch, so that the third temperature-sensitive switch can be manually reset without disassembling the machine. The manual reset device has the following specific structure: a first through hole 521 is formed in the second end face 52 of the housing 5 and corresponds to the second connecting column 91, a push rod 14 is movably arranged in the first through hole 521 in a penetrating manner, one end of the push rod 14 extends into the interior of the housing 5 and is fixedly connected with the second conductive elastic sheet 72 and the second connecting column 91, and the other end of the push rod 14 extends out of the housing 5 for a certain length. The other end of the ejector rod 14 can be arranged to extend out of the bottom of the wall breaking machine, so that the third temperature sensitive switch can be manually reset outside the bottom of the wall breaking machine by pressing the ejector rod 14.

The structure and operation principle of the other parts of this embodiment are the same as those of embodiment 1.
