In the present embodiment, in order to ensure that reverse gear 5 smooth can rotate, it is equipped between the reverse gear 5 and jack-post 6
Bearing, the bearing preferably use oilless bearing.
The operation principle and the course of work of the present invention is as follows：
During specific installation, simultaneous force disk 2 is fixedly connected with the footstalk 1.1 of combustion gas assembly 1, positive gear 4 and potentiometer 7
Shaft 7.1 is fixedly connected.
Press the footstalk 1.1 of combustion gas assembly 1 and rotate counterclockwise【As shown in the arrow in Fig. 9, Figure 10】, gas valve opening
For combustion gas, in the rotation whole process of 1 footstalk 1.1 of combustion gas assembly, when footstalk 1.1, which is rotated by 90 °, reaches centre position, for gas quantity
Reach maximum, from centre position clockwise or counterclockwise, tapered into for gas quantity, i.e., in 1 axis of combustion gas assembly
It is that the order reduced again according to first increasing changes for gas quantity in the rotation whole process counterclockwise of handle 1.1.
In 1.1 rotary course counterclockwise of footstalk, the simultaneous force disk 2 being fixedly mounted on footstalk 1.1 drives double-layer gear 3
1.1 synchronous rotary of footstalk is followed, when double-layer gear 3 rotates counterclockwise, the incomplete gear teeth 3c of lower floor is first engaged with reverse gear teeth 5b,
Reverse gear 5 is driven to rotate clockwise, reverse gear 5 rotates clockwise drives positive gear 4 to rotate counterclockwise again, so that electric
The shaft 7.1 of position device 7 rotates counterclockwise, and the resistance value of potentiometer 7 diminishes；When footstalk 1.1 drives double-layer gear 3 to be rotated by 90 ° it
Afterwards, the incomplete gear teeth 3c of lower floor and reverse gear teeth 5b is disengaged, and the incomplete gear teeth 3b in upper strata enters with positive gear teeth 4b nibble again at this time
Close, drive positive gear 4 to rotate clockwise, so that the shaft 7.1 of potentiometer 7 rotates clockwise, the resistance value of potentiometer 7 becomes
Greatly.
Since potentiometer 7 controls the air blower to gas-cooker air blast oxygenation, when the change of 7 resistance of potentiometer is small, air blower
Rotating speed becomes larger, and air blast oxygenation capacity also becomes larger；When 7 resistance of potentiometer becomes larger, the rotating speed of air blower diminishes, and air blast oxygenation capacity also becomes
It is small；In above-mentioned action process, in rotation is whole, on the one hand control first increases for gas quantity subtracts 1 footstalk 1.1 of combustion gas assembly again
It is small, on the other hand control air blast oxygenation also first to increase and reduce again, so that air blast oxygenation capacity is realized with combustion gas assembly 1 for gas quantity
Bi-directional synchronization, makes household gas range also to increase air blast oxygenation function, can produce more preferable calorific value, reach energy saving effect
Fruit.
