Actuation sensing device and suitable housing thereof

Abstract

The present invention provides an actuation sensing device that includes a driving circuit board, an outer cover, an actuator, and a sensor. The outer cover is disposed on the driving circuit board and has a chamber therein, and the chamber communicates with the outside of the outer cover through a feeding hole and a vent hole in the first side surface. The actuator and the sensor are both disposed in the chamber and are disposed corresponding to the feeding hole. By driving the actuator, the gas in the chamber is discharged outside the outer cover through the vent hole, so that a pressure gradient is generated in the chamber, and gas outside the outer cover enters the chamber through the feeding hole and is monitored by the sensor.

Description

【Technical field】 [0001] This case relates to an actuation sensing device, in particular to an actuation sensing device which uses an actuator to transmit gas, and which is inhaled and exhausted from the side and its applicable casing. 【Background technique】 [0002] At present, human beings pay more and more attention to environmental monitoring requirements in daily life, such as carbon monoxide, carbon dioxide, volatile organic compounds (Volatile Organic Compound, VOC), PM2.5 and other environmental monitoring. Exposure to these gases in the environment will cause adverse effects on the human body. The health impact of the gas is serious and even life-threatening. Therefore, environmental gas monitoring has attracted the attention of various countries, and has gradually become a topic that cannot be ignored in life. [0003] However, in the existing technology, the ambient gas detection instrument is too large, such as an air filter, and it is not convenient for the user...

AI Technical Summary

Problems solved by technology

[0007] Another main purpose of this case is to provide an actuation sensing device with waterproof and dustproof functions at the same time, through the setting of the protective film to filter water vapor and dust, so as to solve the known problems in the process of gas transmission. Moisture or dust enters the interior of the device, causing damage to components, reduced gas transmission efficiency, etc.

[0008] Another main purpose of this case is to provide an electronic device housing suitable for the actuation sensing device, by installing the actuation sensing device that allows the airflow to enter and exit the same side on the mobile phone housing, so that Solve the problem that the known gas sensing device is not conducive to carrying, so that it is impossible to detect the state of the surrounding environment gas anytime and anywhere
