Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0050] The elastic portion 13, the pressure transmission device, and the pressure sensor 15 are all disposed inside the housing 11;

[0051] A processor 2 is electrically connected to the pressure sensor 15 .

[0052] In this embodiment, the pressure detection device is installed inside the medical waste treatment equipment and is fixed to the medical waste treatment equipment through the connection part 12 at the bottom of the shell 11. The connection part 12 and the medical waste treatment equipment can be connected by threads or flanges.

[0053] When the medical waste treatment equipment begins operating, the internal air pressure changes, exerting pressure on the elastic portion 13. This causes a slight deformation, resulting in a change in the resistance of the signal transmission device. Pressure sensor 15 then measures this change in resistance to determine the level of pressure applied to its surface. Generally, the resistance increases with increasing pressure, reflecting the deformation of the elastic portion 13 under load.

[0054] The resistance change output by the pressure sensor 15 is transmitted to the processor 2 electrically connected thereto, and the processor 2 interprets and converts the signal information to generate a voltage or digital signal related to the pressure for further data processing or control applications.
