Description

Technical Field

[0001] The utility model relates to the technical field of stove fans, in particular to a multi-air duct regulating valve for a stove fan.

Background Art

[0002] In the structure of commercial gas stoves, the mixing ratio of air and gas is very crucial. If there is too little air, the gas will not burn fully; if there is too much air, the stove firepower will not meet the requirements and it is easy to blow out the flame. Therefore, regulating and controlling the air intake of the stove fan is a necessary prerequisite for realizing the regulation of the air-fuel ratio. However, the size of the air inlet of the existing stove fans is fixed, and the air intake efficiency cannot be changed. The air intake of the stove fan is only related to the rotational speed, and only the rotational speed can be changed to adjust the air intake to match the adjustment of the gas volume by the gas valve. This method requires meeting the pipe diameter matching and stove model matching, and the applicability is poor. Large stoves can only be matched with large stove fans, and small stoves can only be matched with small stove fans, resulting in the need to design and produce corresponding stove fans for each type of stove, increasing the production cost in disguise and causing waste of resources.
