[0021] Referring to Figure 1-2 Describe a wall breaker according to an embodiment of the present utility model.

[0022] In one embodiment, as Figure 1-2 shown, a wall breaker includes a base 1, and an outer cover 2 and a cup body 3 installed on the base 1. The outer cover 2 covers the periphery of the cup body 3. It further includes a pressure switch device 5 for monitoring the air pressure inside the cup body 3. The pressure switch device 5 is arranged on the side wall of the cup body 3; the cup mouth of the cup body 3 is hermetically closed with a cup cover, and a heating device is provided at the bottom of the cup body 3. A crushing blade 4 is provided at the bottom of the cavity inside the cup body 3. The crushing blade 4 is in transmission connection with a driving motor, and the driving motor is arranged inside the base 1; the pressure switch device 5 is respectively connected to the motor and the heating device, and when the air pressure inside the cup body 3 exceeds a preset air pressure value, the pressure switch device 5 disconnects, so that the driving motor and the heating device stop working.

[0023] Among them, the pressure switch device 5 is used to monitor the air pressure inside the cup body 3. This wall breaker can control the stirring and heating operations of the cup body 3 by the on-off of the pressure switch device 5, thereby controlling the internal pressure of the cup body 3 and preventing potential safety hazards caused by excessive pressure, ensuring safety.

[0024] For the wall breaker provided in the above embodiment, in order to prevent potential safety hazards caused by excessive pressure inside the cup body 3, a pressure switch device 5 is added. The pressure switch device 5 can disconnect when the pressure reaches a certain level, thereby controlling the driving motor and the heating device to stop working, achieving the purpose of keeping the pressure inside the cup body 3 within a safe range and improving the safety of the product.

[0025] In this embodiment, the above wall breaker further includes a control main board. The control main board is electrically connected to the pressure switch device 5, and the pressure switch device 5 is respectively connected to the driving motor and the heating device through the control main board.

[0026] When the air pressure inside the cup body 3 exceeds the preset air pressure value, the pressure switch device 5 disconnects. When the control main board detects the disconnection of the pressure switch device 5, it controls the driving motor and the heating device to stop working. When the air pressure inside the cup body 3 is lower than the preset air pressure value, the pressure switch device 5 conducts; when the control main board detects the conduction of the pressure switch device 5, it controls the driving motor and the heating device to work.

[0027] During specific implementation, when the pressure switch device 5 detects that the air pressure inside the cup body 3 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 will control the driving motor to stop working and at the same time control the heating component to stop heating. When the air pressure inside the cup body 3 is less than the preset air pressure value, it will re-control the driving motor and the heating component to start working. The cooling device 6 starts to cool the cup body 3, enabling the cup body 3 to cool down quickly, thereby reducing the air pressure inside the cup.

[0028] In this embodiment, an operation panel is provided on the outer surface of the base 1, and the operation panel is electrically connected to the control main board, which is convenient for users to operate. Among them, the operation panel can be a mechanical button panel or a touch panel, and the control main board is a PCB circuit board, with mature manufacturing technology and can reduce costs.

[0029] In this embodiment, the above-mentioned pressure switch device 5 includes a silica gel cap 51, a first ejector rod 52, a spring 53, a pressing plate 54, a second ejector rod 55 and a pressure switch 56 that are connected in sequence along the horizontal direction.

One end of it is located on the inner wall of the cup body 3 for detecting air pressure, and the other end is located outside the cup body 3, which is convenient for connecting with the control main board and transmitting signals. Thus, through the control main board, the driving motor and the heating component are controlled to realize the regulation of the air pressure inside the cup body 3 and ensure the safety of the product. At the same time, the pressure switch device 5 is located in the upper part of the cup body 3, which can not only avoid immersion in water but also not interfere with the stirring work of the wall breaker.

[0031] In this embodiment, the convex part is a circular arc convex surface, and the front end of the first ejector rod 52 is a circular arc convex part that matches the inner side of the circular arc convex surface, playing a sealing role. The rear end of the first ejector rod 52 passes through the spring 53 and is connected to the front end of the pressing plate 54. The rear end of the pressing plate 54 is connected to the front end of the second ejector rod 55, and the rear end of the second ejector rod 55 is connected to the pressure switch 56. During specific implementation, such as Figure 2As shown by the pressure conduction direction represented by the arrow, when the air pressure inside the cup body 3 exceeds the preset air pressure value, the air inside the cup body 3 pushes the silica gel cap 51. The silica gel cap 51 is squeezed and deformed, and this deformation is sequentially transmitted to the pressure switch 56 through the first ejector rod 52, the spring 53, the pressure plate 54, and the second ejector rod 55. The pressure switch 56 is disconnected, and the control main board controls the driving motor and the heating device to stop stirring and heating. When the air pressure inside the cup body 3 is less than the preset air pressure value, that is, the air pressure decreases, the silica gel cap 51 is pushed back to its original position, the pressure switch 56 is turned on, and the control main board controls the driving motor and the heating device to start stirring and heating.

[0032] In an implementation manner of this embodiment, the above-mentioned wall breaker further includes a cooling device 6 provided on the side surface of the outer shell of the base 1. The lower end of the cooling device 6 is provided with an air inlet, and the cooling device 6 is connected to the control main board. An air cooling cavity is formed between the inner wall of the outer cover 2 and the outer wall of the cup body 3. The top of the outer cover 2 is provided with an air outlet, and the side surface of the outer cover 2 is provided with an air inlet. The upper end of the cooling device 6 is correspondingly connected to the air inlet. When the air pressure in the cup body 3 exceeds the preset air pressure value, when the control main board detects that the pressure switch device 5 is disconnected, it controls the cooling device 6 to start working.

[0033] In another implementation manner of this embodiment, the above-mentioned wall breaker further includes a cooling device 6 provided inside the base 1.

When the air pressure in the cup body 3 exceeds the preset air pressure value, when the control main board detects that the pressure switch device 5 is disconnected, it controls the cooling device 6 to start working.

[0034] In the above-mentioned embodiment, the cooling device 6 includes an air inlet pipe and a fan provided in the air inlet pipe. The structure is simple, which is convenient for installation and maintenance, and the fan is connected to the control main board.

[0035] In the above-mentioned embodiment, the air outlet includes a plurality of through holes uniformly distributed on the top surface of the outer cover 2, and the air outlet is uniform and efficient.

[0036] Specifically, when implemented, the air inlet of the air inlet pipe is communicated with the air cooling cavity; as Figure 1 shown by the air flow direction represented by the arrow, the cold air passes through the cooling device 6 from the air inlet, enters the air cooling cavity through the air inlet, blows towards the side wall of the cup body 3 to cool the cup body 3, and the hot air passing through the side wall of the cup body 3 is then discharged from the air outlet on the top of the outer cover 2 from the air cooling cavity, which can quickly reduce the temperature inside the cup body 3 and achieve the effect of quickly opening the sealed cup lid.
