The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0037] Please see Figure 1 and Figure 2This utility model provides a detection device 1, which includes a container 11, a connecting member 12, a pressure sensor 13, a first pipe 14, a second pipe 15, a one-way valve 16, a first filter element 17, a second filter element 18, and a support 19. The container 11 is connected to the connecting member 12 and is used to store a medium. The pressure sensor 13 is connected to the connecting member 12 so that the pressure sensor 13 is connected to the container 11, and is used to detect the pressure of the medium inside the container 11. The first pipe 14 connects the inlet end of the one-way valve 16 to the external environment. The second pipe 15 connects the outlet end of the one-way valve 16 to the connecting member 12. A one-way valve 16 is mounted on the bracket 19. The one-way valve 16 allows media from the external environment to enter the container 11, but prevents media inside the container 11 from flowing out. Specifically, when the pressure of the media inside the container 11 is lower than the pressure of the media in the external environment, the one-way valve 16 opens, allowing media from the external environment to enter the container 11. When the pressure of the media inside the container 11 is greater than or equal to the pressure of the media in the external environment, the one-way valve 16 closes. A first filter element 17 is installed in the first pipe 14, connecting the inlet of the one-way valve 16 to the external environment. The first filter element 17 filters the media flowing from the external environment through the one-way valve 16 and into the container 11, thereby filtering out dust, particles, and other foreign matter in the media and preventing the one-way valve 16 from malfunctioning due to dust, particles, or other foreign matter. The second filter element 18 is installed inside the second pipe 15. The second filter element 18 connects the outlet end of the one-way valve 16 and the connecting piece 12, so that the second filter element 18 connects to the container 11.

[0038] It should be noted that the first filter element 17 and the first pipe 14 are interference-fitted, so that the first filter element 17 is fixed inside the first pipe 14 and will not be displaced by the medium flowing through the first pipe 14. The second filter element 18 and the second pipe 15 are interference-fitted, so that the second filter element 18 is fixed inside the second pipe 15 and will not be displaced by the medium flowing through the second pipe 15.
