A ratchet wheel is fixed on an output shaft of the timing device, and one end of a torsion-spring is fixed on the ratchet wheel and the other end of the torsion-spring is fixed on the basic body of the timing device. When the timing device runs, the torsion spring turns around to drive the ratchet wheel to turn, and then the detent is moved to drive the turning of gear, so as to make the valve core revolve to close the gas channel to reach the aim of closing the gas. The utility model can control the closing time of gas cooker according to the need of users and then the security of using the gas cooker can be enhanced.

Description

Gas hob with timer

technical field

The utility model relates to a gas stove with a safety protection device, in particular to a gas stove with a timing device.

Background technique

At present, the operation of gas stoves requires manual control. When boiling water or stewing soup and other situations that require long-term use, people often leave the stove to do other things, so that they forget what is being stewed on the gas stove. It is very dangerous to burn the pot dry, or even the soup boils and spills out to extinguish the flame and cause gas leakage.

Contents of the invention

The purpose of the utility model is to provide a gas stove with a timing device, which can turn off the gas regularly when people leave the stove, so as to prevent the occurrence of the above-mentioned dangerous phenomenon.

The purpose of this utility model is achieved in the following way: a gas cooker with a timing device, including a valve shaft installed on the frame of the gas cooker, an ignition button fixed at one end of the valve shaft, a valve core and a valve body connected to the other end. Yes: a timer is installed on the frame of the gas stove, the output shaft of the timer is fixed to the coaxial ratchet, one end of the torsion spring is fixed on the ratchet, and the other end is fixed on the base of the timer. The end of the output shaft is installed in the counterbore in the middle of the valve core with sliding fit. The gas outlet end of the valve body is connected with the original valve body, and the gas inlet end is connected with the gas inlet pipe. The gear is fixed on the upper part of the valve core, and the sector gear meshing with the gear is fixed on the On the valve shaft, the ratchet matched with the ratchet is fixed on the upper end surface of the gear, and there is a return spring under the sector gear.

The positive effect of the utility model is that the closing time of the gas stove can be controlled according to people's needs, which improves the safety of the gas stove and prevents the pot from being burned dry due to negligence and forgetting to turn off the gas switch, and even the soup boils and overflows to extinguish the flame, causing Risk of gas leakage.

Detailed ways

As shown in Figure 1, a gas stove with a timing device described in the utility model includes a valve shaft 2 installed on the gas stove frame 2, an ignition button 1 fixed at one end of the valve shaft 2 and a valve core connected to the other end. 7 and the valve body 6, a timer 18 is also installed on the gas stove frame 2, the timer output shaft 12 is fixed on the coaxial ratchet 15, one end of the torsion spring 16 is fixed on the ratchet 15, and the other end is fixed on the timer 18 substrate, the valve core There is a counterbore in the middle of 9, and a spring 10 is installed in the hole, and the end of the timer output shaft 12 is slip-fitted and installed in the counterbore in the middle of the valve core 9, the gas outlet of the valve body 8 is connected with the valve body 6, and the gas inlet is connected with the gas inlet 11 is connected, the gear 13 is fixed on the upper part of the valve core 9, the sector gear 4 meshing with the gear 13 is fixed on the valve shaft 2, the pawl 14 matched with the ratchet 15 is fixed on the upper end surface of the gear 13, and there is a return spring under the sector gear 4 5.

When the gas cooker is in normal use, press and rotate the ignition button 1 clockwise, the valve core 7 rotates open, and at the same time the sector gear 4 moves downwards and rotates with the gear 13, driving the valve core 9 to rotate, opening the gas channel, and connecting the gas Air intake pipe 11, can normally use gas cooker, when unclamping ignition button 1, under the effect of return spring 5, sector gear 4 returns to normal position.

When it is necessary to turn off the gas regularly, turn the timing knob 17 clockwise to rotate the output shaft 12 through the timer 18, drive the ratchet 15 to rotate, the torsion spring 16 is stretched, and the output shaft 12 is timed and limited by the timer 18 to start Timing, when the time is up, the output shaft 12 limit is released, and the ratchet 15 is driven to rotate under the pulling force of the torsion spring 16, and the ratchet 15 is driven to rotate the gear 14, as shown in Figure 2, because the ratchet 15 is provided with 4 A ratchet, ratchet 14 drives ratchet 15 to rotate 90 degrees at every turn, thereby makes spool 9 rotate 90 degrees together, closes gas channel, reaches the purpose of regularly closing gas. Spring 12 makes spool 9 and valve body 8 cooperate closely to prevent dew gas, and timer 18 is a mature technology, so ominous state.
