Air door adjusting mechanism of gas stove

Abstract

The invention relates to an air door adjusting mechanism of a gas stove. The air door adjusting mechanism comprises an injection pipe, a nozzle holder and a nozzle installed on the nozzle holder, thejet tip of the nozzle faces the air inlet end of the injection pipe, and the air door adjusting mechanism is characterized in that the the air door adjusting mechanism further comprises an air adjusting plate, an elastic part and a limiting part which are installed on the nozzle holder. Compared with the prior art, the air door adjusting mechanism has the advantages that the elastic part is arranged, thus the air adjusting plate is close to the air inlet end of the injection pipe in the direction parallel to the axis of the injection pipe, when the air adjusting plate is in the state of applying force to the elastic part, the elastic part can give the air adjusting plate a rebound force, the air adjusting plate can be rebounded and stay in a position that can give a certain primary air, and is finally limited by the limiting part, the situation that an air flap of the air adjusting plate is rotated by mistake during the actual use of a user to close the air door can be effectively avoided, thus the situation that a burner is in a bad combustion state for a long time is avoided, meanwhile the air adjusting plate can also be conveniently adjusted according to the combustion conditions, and different air sources and use conditions are met.

Description

technical field [0001] The invention relates to the technical field of gas cookers, in particular to an air door adjustment mechanism of a gas cooker. Background technique [0002] Most of the existing cooker burners on the market are atmospheric burners, which require pre-mixed part of the primary air, which requires a damper opening size adjustment device to adjust the amount of pre-mixed primary air required. At present, there are two most common methods: one is to change the effective circulation area of ​​the primary air suction port by rotating the air regulating plate and moving the air regulating plate back and forth, thereby adjusting the suction volume of the primary air; this form of air regulating When the air regulating plate reaches the ejection tube, it continues to rotate in the direction of the ejecting pipe, which will cause the air regulating plate to be stuck and not easy to rotate; the second is that the air regulating plate is fixed on the ejecting pipe...

Problems solved by technology

At present, there are two most common methods: one is to change the effective circulation area of ​​the primary air suction port by rotating the air regulating plate and moving the air regulating plate back and forth, thereby adjusting the suction volume of the primary air; this form of air regulating When the air regulating plate reaches the ejection tube, it continues to rotate in the direction of the ejecting pipe, which will cause the air regulating plate to be stuck and not easy to rotate; the second is that the air regulating plate is fixed on the ejecting pipe and can be rotated. The amount of primary air intake is changed by changing the degree of overlap between the opening of the air regulating plate itself and the primary air suction port; this form of air regulating plate often causes adjustment experience due to factors such as the rough contact surface between the ejector tube and the air regulating plate, and the force of the spring. bad

For example, a Chinese utility model patent with a patent number of ZL201420837557.6 (authorized announcement number of CN204460316U) discloses a method of closely fitting the movable damper through rivets and arc-shaped grooves to limit the opening of the damper due to misoperation. Change at will, but the incorrect position of the air regulating plate, such as the damper is too small, will lead to insufficient primary air, resulting in bad combustion conditions such as long flames, yellow fire, etc., poor combustion quality, increased generation of harmful gases, and endangering the health of users; too large damper Inhaling too much air at one time reduces the thermal efficiency of combustion and causes energy waste
