Description

Technical Field

[0001] This utility model relates to a fixing device for an air volume sensor, and in particular to an air volume sensor fixing box suitable for various types of wall-hung boilers. Background Technology

[0002] As is well known, airflow sensors are widely used in gas-fired wall-hung boilers, industrial combustion systems, and air conditioning and ventilation equipment. Their main function is to monitor the airflow generated by the fan to ensure combustion efficiency and safety. In wall-hung boiler systems, airflow sensors are typically used to detect the airflow required for combustion and provide data to the control system to adjust the combustion process, ensuring complete combustion of the gas and thus improving thermal efficiency.

[0003] Currently, airflow sensors are mainly installed using screw fixing, snap-on mounting, and adhesive methods. Screw fixing is a common method, where the airflow sensor is mounted on a bracket or mounting plate inside the wall-hung boiler using screws. While this method is simple in structure, the screws may loosen over time, affecting the stability of the airflow sensor. Furthermore, the presence of screw holes can lead to air leakage, thus affecting the sensor's measurement accuracy.

[0004] Another installation method is snap-on installation, which uses snap-on or slot structures for fixation. The installation process is relatively convenient and can be completed without additional tools. However, the fixing strength of this method is limited, and it may loosen due to vibration or thermal expansion and contraction during long-term use, thus affecting the stability of the sensor.

[0005] In addition, some airflow sensors are fixed using adhesive, that is, the sensor is pasted to the installation position with strong adhesive. This method avoids air leakage problems caused by screw holes to a certain extent, but due to the limited adhesive strength, it may fall off after long-term use. At the same time, the adhesive method is more inconvenient for later maintenance. If the sensor is damaged or needs to be replaced, it may be necessary to destroy the original installation structure.

[0006] In summary, existing installation methods for airflow sensors all have certain shortcomings, especially in high-temperature, high-humidity, or long-term vibration environments, where traditional installation methods struggle to balance stability and sealing. Furthermore, due to the precision of the sensor circuit board, mechanical stress or external forces during installation can damage it, affecting the sensor's lifespan and measurement accuracy. Therefore, there is still a need for an improved airflow sensor mounting structure that provides reliable fixation, ensures sealing, and facilitates installation and maintenance. Summary of the Invention

[0009] In specific implementation, when the first box (110) is connected to the second box (120), a sensor slot (130) is provided between the bottom of the first box (110) and the second box (120), wherein the air volume sensor (10) is fixedly inserted into the sensor slot (130).
