Background technique

The existing gas stove switch only has two working states of on or off. When it is in the open state, the gas stove burns, so people cannot leave the gas stove. .

Contents of the invention

The purpose of this utility model is to provide a gas stove timing switch, which can regularly deliver gas to the gas stove, and automatically cut off the gas source when the set time is up, so even if people leave the gas stove in the burning state for a short time, they can Can ensure the safety of the gas stove.

Above-mentioned purpose of the invention is realized by following technical scheme, a kind of gas cooker timing switch, it comprises timer, and timer comprises timing knob, time dial, clock mechanism, timing and clock drive shaft, and its gist is to set on the timer There is a gas inlet valve; the gas inlet valve includes a valve body, a valve, and a valve stem; the valve body is provided with an air inlet hole, a gas delivery hole and a valve hole matching the valve; a reset device is installed between the valve stem and the valve body. spring; the timer is also provided with a push rod that can move downward against the valve stem, and a reset spring is arranged on the push rod;

Above-mentioned gas cooker timing switch, one of its structures is that rubber sealing ring, M type rubber sealing ring are housed on valve body, valve stem.

Above-mentioned gas cooker timing switch, one of its structures is that timing sound alarm socket device is housed on the timing knob.

Above-mentioned gas cooker timing switch, one of its structures is that the timing sound alarm socket device is to have a hole on the timing knob, a bridge cylinder and a back-moving spring are housed in the hole, and a socket is housed on the time dial; Pole, the socket conduction.

The utility model is installed on the gas stove, the air inlet is connected with the air inlet pipe, and the air delivery hole is connected with the air inlet of the gas stove switch. Press the push button, turn the timing knob to the position of the time dial that needs to be set, and then turn on the gas stove switch, and the gas stove will be ignited. When the timing knob goes back to the original position, the set time is up, and the valve is upwards to close the valve hole. Because the utility model is installed on the gas pipe of the gas range switch, the combustion working time of the gas range can be fixed. With this device, when the set time is reached, it can automatically close the gas source. Therefore, people can ensure the safety of the gas range even if they leave the burning gas range for a short time. In addition, the utility model can be made into both regular and irregular timing with slight changes.

Detailed ways

Represented by Fig. 1-6 is an embodiment of the present utility model, and it comprises timer 1, and timer 1 comprises timing knob 2, time dial 3, clock mechanism 4, timing and clock drive shaft 5; A gas inlet valve 6 is provided, and the gas inlet valve 6 includes a valve body 7, a valve 8, and a valve stem 9; the valve body 7 is provided with an air inlet 10, an air delivery hole 11 and a valve hole 12 matching the valve 8 Back-moving spring 13, rubber sealing ring 17, M type rubber sealing ring 18 are housed between valve stem 9 and valve body 7; Back-moving spring 15 is housed on 14; Push button 16 and timing sound alarm socket device 19 that control ejector rod 14 lower tops are housed on timing knob 2; Timing sound alarm socket device 19 has hole 20 on timing knob 2, and hole 20 dresses Have bridging cylinder 21, back-moving spring 22, socket 23 is housed on the time dial 3, when bridging cylinder 21 bumps into the two poles of socket 23, socket 23 conduction.

The installation, operation and action process of the present embodiment are as follows: the gas stove timing switch 26 of the present embodiment is installed on the gas stove 27, the air inlet 10 is connected with the air inlet pipe 29, the air inlet 11 is connected with the gas stove switch 28 Air to mouth. If the gas range 27 needs regular work, press the push button 16, rotate the timing knob 2 to the position where the time needs to be set on the time dial 3, and turn it to the 15-minute scale position. Press down, the ejector rod 14 overcomes the resistance of the return spring 15 and moves downward, pushes the valve stem 9 downward, the valve stem 9 overcomes the elastic force of the return spring 13 and moves downward, and the valve 8 integrated with the valve stem 9 also moves downward. At this time, the knob 2 is reset, and the ejector rod 14 is also reset under the action of the return spring 15, and the valve stem 9 is supported by the bottom of the timing knob 2, and as a result, the valve hole 12 is always opened, and at this time, the gas or natural gas flows from the air inlet 10 enters, because rubber sealing ring 17, M type rubber sealing ring 18 are arranged, so coal gas or natural gas can only be transported to gas range switch 28 from gas delivery hole 11, open gas range switch 28, a cooker of gas range 27 promptly burns work . At the same time, the clockwork 24 and the clock mechanism 4 of the timer 1 start to act, and the timing and clock transmission shaft 5 drives the timing knob 2 to rotate counterclockwise. When the time reaches 15 minutes, the timing knob 2 returns to its original position, and the timing knob 2 The hole at the bottom is aligned with the valve stem 9, and the valve stem 9 resets upward under the action of the return spring 13, so the valve 8 moves upwards to close the valve hole 12, and gas or natural gas can no longer be input into the gas stove switch 28, gas stove 27 A burning hob is extinguished. Simultaneously, bridging cylinder 21 is ejected under the effect of back-moving spring 22, runs into the two poles of socket 23 on the time dial 3, and socket 23 conduction, as connecting timing sound alarm device, can send alarm sound.

From the description of the above-mentioned structure, installation, operation and action process of the embodiment, the utility model can make the existing gas stove more convenient and safer to use.
