[0020] Reference Figure 1An underwater oxygen measuring device includes a first housing 1 and a second housing 2, which are threaded together. In the diagram, the lower side is the first housing 1, and the upper side is the second housing 2. When the first housing 1 and the second housing 2 are engaged, the overall shape is spherical. The first housing 1 has a convex thread, and the second housing 2 has a concave thread. A housing sealing gasket is located on the side of the concave thread away from the convex thread. When the convex and concave threads are fully engaged, the housing sealing gasket is compressed, and the first housing 1 and the second housing 2 achieve a seal. The housing sealing gasket is made of polytetrafluoroethylene (PTFE). PTFE gaskets have excellent chemical stability and extremely low surface energy; they hardly react with any chemicals, giving them excellent impermeability when exposed to water. Their dense molecular structure makes it difficult for water molecules to penetrate.

[0021] The first housing 1 is provided with a water-proof and breathable membrane 3 and a support platform 4. The water-proof and breathable membrane 3 can block water and allow air to pass through. The water-proof and breathable membrane 3 is located on one side of the first housing 1, that is, in the figure, the water-proof and breathable membrane 3 is located at the lower end of the first housing 1.

[0022] The mounting platform 4 is located in the middle of the first housing 1. An oxygen measuring instrument 5 is mounted on the mounting platform 4. A platform sealing gasket 6, made of nitrile rubber, is placed between the oxygen measuring instrument 5 and the mounting platform 4. The nitrile rubber sealing gasket separates the gas collecting end located in the first housing 1 from the analysis end located in the second housing 2, ensuring the safety of the oxygen measuring instrument 5. The mounting platform 4 is equipped with reinforcing ribs to improve the pressure resistance of the outer shell. The mounting platform 4 is made of metal, specifically stainless steel.

[0023] A temperature sensor 7 is installed at one end of the oxygen measuring instrument 5, and the temperature sensor 7 is positioned close to the waterproof and breathable membrane 3. The oxygen measuring instrument 5 is equipped with a Bluetooth interface, which enables wireless transmission. The status of data transmission can be used to promptly detect whether the underwater oxygen measuring device is working properly.

[0024] This utility model adopts a spherical shell, which distributes the force more evenly and can effectively withstand water pressure, protecting the internal devices of the shell; it uses a threaded polytetrafluoroethylene sealing gasket, which can effectively withstand water pressure while maintaining airtightness; a platform sealing gasket 6 is set between the oxygen measuring instrument 5 and the mounting platform 4; the oxygen measuring instrument 5 is equipped with a temperature sensor 7, which makes the data more accurate.
