In specific implementation, Figure 4 As shown in the direction of pressure conduction represented by the middle arrow, when the internal air pressure of the cup body 200 exceeds the preset air pressure value, the air in the cup body 200 pushes the silicone cap 510, and the silicone cap 510 is squeezed and deformed, and the deformation is transmitted to the pressure switch 560 through the first push rod 520, the spring 530, the pressure plate 540 and the second push rod 550 in sequence. The pressure switch 560 is disconnected, and the control mainboard controls the driving device and the heating device to stop stirring and heating; when the internal air pressure of the cup body 200 is less than the preset air pressure value, that is, the air pressure decreases, the silicone cap 510 is pushed to reset, the pressure switch 560 is turned on, and the control mainboard controls the driving device and the heating device to start stirring and heating.

[0050] In one embodiment, if Figure 3 As shown, the base 100 is also provided with a cooling device 600, and the cooling device 600 is mainly used to cool the cup body 200;

[0051] The cooling device 600 is disposed on the outer surface of the base 100 and connected to the control mainboard; a cold air inlet is disposed at the lower end of the cooling device 600, and the upper end of the cooling device 600 is connected to the air cooling cavity 301 of the outer cover 300, and an air outlet is disposed at the top of the outer cover 300;

[0052] Furthermore, the cooling device 600 includes an air inlet duct and a fan arranged in the air inlet duct, and the fan is connected to the control mainboard.

A through hole for connecting the air inlet duct is provided on the side wall of the outer cover 300. The upper end of the cooling device 600 is connected to the air cooling chamber 301 of the outer cover 300 through the through hole.

[0054] In one embodiment, if Figure 5As shown, the cooling device 600 is installed inside the base 100, and a base air outlet is opened on the top of the base 100 (not shown in the figure), and the base air outlet is within the covering range of the outer cover 300; a base air inlet is opened on the side of the base 100, and when the fan is running, it drives the external air flow to enter from the base air inlet, enter the air cooling chamber 301 through the base air outlet, and finally flow out from the air outlet on the top of the outer cover 300.

[0055] In one embodiment, the base 100 is also provided with a speaker assembly, which emits a warning sound to remind the user.

[0056] In one embodiment, the base 100 is also provided with a warning light, which illuminates to remind the user.

[0057] The specific use of the utility model is further described below:

[0058] First, the cup body 200 is installed on the base 100, and the crushing blade 210 is connected to the driving device 110; then, the outer cover 300 is assembled on the base 100, and the knob 420 is turned, and the limiting portion 310 of the outer cover 300 cooperates with the limiting groove 430 of the knob 420, so that the outer cover 300 is limited to the base 100, and the safety switch 410 is turned on.

[0059] Next, the wall breaking machine is operated, and the crushing blade 210 and the heating device are operated.

[0060] During the food preparation process, the pressure switch device 500 detects the pressure in the cup body 200 in real time. When the pressure switch device 500 detects that the air pressure in the cup body 200 exceeds the preset air pressure value, it sends a disconnection signal to the control main board. After receiving the disconnection signal, the control main board controls the driving device to stop working and controls the heating device to stop heating. At this time, the pressure in the cup body 200 is reduced by naturally cooling the cup body 200 or by blowing air to cool down the cooling device 600, so as to reduce the temperature of the cup body 200 and reduce the pressure in the cup body 200.

[0062] During the food preparation process, the user turns the knob 420, the outer cover 300 and the base 100 are unlocked, and the knob shaft 422 triggers the safety switch 410 to disconnect. After the control mainboard receives the disconnection signal, it controls the driving device to stop working and controls the heating device to stop heating;

[0063] Optionally, it can be programmed so that during the food preparation process, if the safety switch 410 is disconnected, the speaker assembly will emit a warning sound or the prompt light will light up to remind the user that the wall-breaking machine is interrupted, thereby serving as a warning and safety protection.

[0064] After the food is prepared, the driving device stops working, the heating device stops heating, and the cooling device 600 starts to cool down the cup body 200 quickly; when the cooling device 600 is running, the user turns the knob 420 to unlock the outer cover 300 and the base 100, and at the same time, the knob shaft 422 triggers the safety switch 410 to disconnect. After the control mainboard receives the disconnection signal, the speaker assembly emits a warning sound or the prompt light lights up to remind the user that the cooling work is interrupted and the cooling of the cup body 200 is not completed, which plays a warning and safety protection role to prevent the cup cover from being opened when the cup body 200 is not completely cooled, that is, when the pressure in the cup body 200 is too high, to prevent safety hazards caused by excessive pressure.

[0065] The utility model provides a safety protection device 400 and a pressure switch device 500, so that the wall breaking machine is safer to use.
