Abstract

The invention provides an electrochemical gas sensor. The sensor comprises an upper cover, an electrode group, a platy main body shell and a rear cover, wherein the upper cover and the main body shell are buckled to form a cavity; the electrode group is formed by superposing a working electrode, first glass wool, a reference electrode, second glass wool and an auxiliary electrode in turn; the upper cover comprises a gas inlet through hole and a gas diffusion groove; the gas diffusion groove is formed at the bottom of the upper cover; the gas inlet through hole passes through the upper cover and is communicated with the gas diffusion groove; the main body shell comprises an electrolytic cell groove which is formed on the top of the main body shell, and a liquid injection through hole which passes through the main body shell and is communicated with the electrolytic cell groove; and the rear cover is arranged in the liquid injection through hole. The problem that the microminiaturization development of related monitoring devices is limited to a certain extent because the external dimension of the electrochemical gas sensor is large in the prior art is solved, and the aim of microminiaturizing the electrochemical gas sensor is fulfilled.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic chips, and in particular to a compact chip electrochemical gas sensor. Background technique [0002] With the continuous development of electronic technology, electrochemical gas sensors are widely used in related monitoring devices due to their advantages of no heating, low power consumption, anti-interference, high sensitivity, and good linear characteristics. [0003] However, in the process of realizing the present invention, the inventors found that due to the large size of the electrochemical gas sensor in the prior art, the miniaturization development of related monitoring devices was limited to a certain extent, so the size of the electrochemical gas sensor Larger problems urgently need to be resolved. Contents of the invention [0004] An embodiment of the present invention provides an electrochemical gas sensor to solve the defect in the prior art that the developme...
