Abstract
Description
Technical Field
[0001] This utility model relates to a bracket, and more particularly to a movable bracket assembled in a wall-hung boiler for fixing an air volume sensor. Background Technology
[0002] Airflow sensors are now 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 three methods: screw fixing, snap-on installation, and adhesive bonding. 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 simple in structure, the screws may loosen over time, affecting the sensor's stability. Furthermore, the presence of screw holes can lead to air leakage, affecting the sensor's measurement accuracy. Snap-on installation uses clips or slots for fixing, making installation relatively convenient and requiring no additional tools. However, this method has limited fixing strength and may loosen over time due to vibration or thermal expansion and contraction, affecting sensor stability. Additionally, some airflow sensors are fixed using adhesive bonding, where the sensor is glued to the mounting position with strong adhesive. This method avoids air leakage problems caused by screw holes to some extent, but due to limited adhesive strength, it may detach after prolonged use. Moreover, adhesive bonding is inconvenient for later maintenance; if the sensor is damaged or needs replacement, the original installation structure may need to be damaged. 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.
