AI Technical Summary
The existing fully premixed gas heating and hot water boilers use a separate structure for the fan and Venturi premixer, which results in high component costs, complex installation, and insufficient air-gas mixing, which can easily lead to abnormalities such as noise.
The Venturi premixed integrated fan is adopted. The premixer body and the cover plate body are integrally die-cast to form an integrated structure. Combined with the design of limiting boss and positioning bolt, it realizes sealed installation and multi-angle adjustment, improving airtightness and applicability.
It reduces costs, simplifies the installation process, improves airtightness and air-fuel mixing, reduces noise, and adapts to the installation needs of different wall-hung boiler structures.
