Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and exemplary embodiments.

[0023] Such as Figure 1-5 As shown, the main structure of a sampling type fast primary battery oxygen sensor includes an upper cover shell 1 and a main shell 2 . There is an air inlet 9 and an air inlet 10 above the upper cover shell 1. The air inlet 9 is thinner than the air inlet 10. The upper cover shell 1 contains an inner shell cylinder 19, and the air inlet corresponds to the At the center of the cylinder 19, cover the top cover shell 1 on the main shell 2, the edge 25 of the upper shell and the edge 24 of the main shell are completely fitted, the cylinder 19 of the top cover shell and the top of the main shell 2 The raised spacer 20 fits perfectly and can be embedded, and the edges of the upper cover shell 1 and the main shell 2 ...

Abstract

The invention discloses a sampling type rapid primary battery oxygen sensor which comprises an external main shell and an upper cover plate shell, a gas inlet and a gas extraction opening are formed in the upper portion of the upper cover plate shell, a space between the upper cover plate shell and the main shell forms an induction gas chamber of a primary battery, and external gas enters the induction gas chamber through the gas inlet, oxygen in the gas enters the reaction gas chamber through the oxygen permeable membrane for chemical reaction, and the rest of impurity gas flows out through multiple micropores in the edge and is pumped away through the gas pumping cavity and the gas pumping opening. An anode bar and a microporous cathode are arranged in the reaction gas chamber. The sponge block with adsorbability is placed in the reaction gas chamber and attached to the anode bar and the microporous cathode, and after the electrolyte is used and consumed, the sponge block ensures that the electrolyte is still transferred to the electrode to react between the microporous cathode and the anode bar. The arranged pressure balance gas chamber ensures that the electrolyte in the reaction gas chamber cannot overflow, the oxygen permeation membrane is not subjected to stress action and is not easy to separate and crack, and the service life of the sensor is prolonged.

Description

technical field [0001] The invention relates to the field of medical oxygen sensors, in particular to a sampling type fast original battery oxygen sensor. Background technique [0002] The analysis and determination of oxygen is widely used in laboratory, biology, medicine, chemical industry, energy and many other fields. Oxygen sensor is the most researched and most mature type of sensor among all gas sensors. [0003] Oxygen sensors can be divided into electrochemical oxygen sensors, optical fiber oxygen sensors, thermomagnetic oxygen sensors, semiconductor resistive oxygen sensors, etc. according to different working principles. Electrochemical oxygen sensors usually use electrochemical reactions to measure oxygen. This type of sensor has the advantages of high sensitivity, wide measurement range, and short response time. It is widely used in chemical, medical, biological, and military fields. It is the most mature technology at present. The most widely used oxygen sens...
