[0002] At present, in the field of oxygen preparation technology, oxygen production components for household or medical use are basically molecular sieve oxygen production, and their working principle is to separate oxygen and nitrogen in the air through molecular sieve pressure swing adsorption to obtain high-concentration oxygen. The Chinese patent with application number CN202123063580.3 discloses an oxygen production component, including a combination valve located above the oxygen production component; an oxygen storage tank located in the middle of the bottom of the oxygen production component; a first sieve cylinder located on one side of the oxygen production component, connected to the combination valve through a first pipeline, and connected to the oxygen storage tank through a third pipeline; a second sieve cylinder located on the other side of the oxygen production component, connected to the combination valve through a second pipeline, and connected to the oxygen storage tank through a fourth pipeline; a fifth pipeline located in the oxygen storage tank, one end of which is connected to the third pipeline and the other end is connected to the fourth pipeline. In the above patent, pressure sensors are provided in the first sieve cylinder and the second sieve cylinder, and the pressure in the first sieve cylinder and the second sieve cylinder is sensed by the pressure sensor to realize real-time detection. As an electronic component, the pressure sensor has the requirement of sensitivity, and it has the defect of being easily damaged or having reduced accuracy, so the pressure sensor needs to be frequently maintained or replaced. However, the existing pressure sensors are all fixedly installed inside the first sieve drum and the second sieve drum. The disassembly process is very cumbersome.

Disassembly is time-consuming and laborious, and so is installation. Therefore, it is necessary to optimize the installation and disassembly structure of the pressure sensor to facilitate the subsequent maintenance or replacement of the pressure sensor.
