When 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.
It presses the footstalk 1.1 of combustion gas assembly 1 and rotates 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 value, clockwise or counterclockwise from centre position, is tapered into for gas quantity, i.e., in 1 axis of combustion gas assembly
It is according to first increasing the sequence reduced again variation for gas quantity during the rotation counterclockwise of handle 1.1 is whole.
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 layer is first engaged with reversed gear teeth 5b,
Reverse gear 5 is driven to rotate clockwise, reverse gear 5 rotates clockwise drives positive gear 4 to rotate counterclockwise again, to make electricity
The shaft 7.1 of position device 7 rotates counterclockwise, and the resistance value of potentiometer 7 becomes smaller；When footstalk 1.1 drives double-layer gear 3 to be rotated by 90 ° it
Afterwards, the incomplete gear teeth 3c of lower layer and reversed gear teeth 5b is disengaged, and the incomplete gear teeth 3b in upper layer enters with positive gear teeth 4b nibble again at this time
It closes, positive gear 4 is driven to rotate clockwise, to make the shaft 7.1 of potentiometer 7 rotate clockwise, the resistance value of potentiometer 7 becomes
Greatly.
Since potentiometer 7 controls the air blower being oxygenated to gas-cooker air blast, 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 becomes smaller, 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
Small, on the other hand control air blast oxygenation also first increases reduces again, to make air blast oxygenation capacity be realized for gas quantity with combustion gas assembly 1
Bi-directional synchronization, air blast oxygenation function can be increased by making household gas range also, can be generated better calorific value, be reached energy-efficient effect
Fruit.
