AI Technical Summary
The fixed connection between the ejector tube and the fire plate channel of the traditional burner head makes cleaning and maintenance inconvenient, and the whole unit needs to be replaced when damaged, resulting in high maintenance costs and poor flexibility.
The design features a detachable fire plate base and ejector base, achieving a modular structure that allows for individual disassembly and replacement of the ejector base or fire plate base. This ensures automatic alignment and connection between the channel and the ejector tube, and enhances airtightness and combustion efficiency through a sealing structure.
It simplifies the cleaning process, reduces maintenance costs, avoids overall scrapping, improves combustion efficiency and sealing reliability, and reduces unit costs.
