Abstract

The utility model relates to a timing automatic extinguishing apparatus which is assembled by a mechanical timer and a ball valve in a gas pipeline for solving the technical problem that a gas cooker is automatically extinguished on time. The utility model is characterized in that magnetic steel 9 at the bottom of a knob arm exactly stops above a pipeline valve 2 when a timer 6 lies in a static starting position, and a steel ball valve 5 is attracted to block the valve 2; the magnetic steel 9 at the bottom of the knob arm can attract and drive the steel ball valve 5 to open and automatically close the valve 2 when the timer rotates in clockwise direction or counter-clockwise direction. Thus, the utility model realizes purposes.

Description

The timing automatic extinguishing means of gas-cooker machinery formula

The utility model is to be used for existing gas-cooker, as the timing automatic a kind of device that extinguishes gas-cooker.It is made of jointly " ball valve " two parts be made up of globe valve, valve, ball valve chamber in mechanical timer (as using on the electric fan) and the gas pipeline.

Existing a kind of gas-cooker pressure-reducing valve has added the ball valve of being made up of globe valve, valve, ball valve chamber of explosion-proof a, anti-gas-leak on it.When using gas-cooker, if when a large amount of gas leakage having taken place maybe will ignite fuel cartridge, the ball valve in the ball valve just can automatic-closing valve, prevented the generation of accident, but it does not possess the timing automatic function of extinguishing.Its structure and function can be consulted the specification of manufacturer.

Because current rhythm of life is accelerated, and seizes every minute and second, do he thing person there are plenty of such people while cooking.In pot, shed often dense burnt burning childhood, just know and also cooking food on the kitchen range, but late! The purpose of this utility model is exactly: when the time of heating up water, cooking is longer, adopted this utility model device after, you can go to do other matters to the greatest extent relievedly.Then, it just can be accurate, in time the automatic self-closing gas kitchen range.

The utility model is formed (Fig. 1 that consults Figure of description) by mechanical timer (the arm below of timer turn-knob studs with a ferromagnetic little magnet steel) jointly with valve and steel small ball in " r " type gas pipeline.When timer static and when being parked in original position, the little magnet steel of its turn-knob arm below, just in time be parked in pipeline valve directly over, though every very thin tube wall, the steel small ball still can be attracted by magnet steel and be parked in the valve place valve is blocked.When clockwise direction rotation timer turn-knob gave regularly, the steel small ball was attracted by the little magnet steel under the turn-knob arm and brings to bottom the ball valve chamber, and valve opening is opened fuel cartridge then, and gas-cooker just can be struck sparks and burnt.Subsequently, timer is revolution counterclockwise under self clockwork spring drives, and when turn-knob arm during through the ball valve chamber, its arm little magnet steel down still can attract and drive the steel small ball across tube wall and roll thereupon, is parked in original position valve place at last.At this moment, the steel small ball just can reach the timing automatic purpose of extinguishing gas-cooker tightly with valve closing under the double action of little magnet steel and gaseous-pressure, and this is a technical solution of the utility model.

The utility model is compared with existing gas-cooker, owing on pipeline, having set up the device that timing, automatic self-closing gas extinguish, just can make the people in the long time of cooking, go to do other matters without single devotion, improved time availability: take place because of the incident of having stopped to burn food and burn out pot kettle again, just avoided the certain economic loss, this is an advantage of the present utility model.

Figure of description Fig. 1 is the schematic top plan view of the utility model device.Wherein: 1 is " r " shape gas pipeline, and 6 are mechanical timer (being in definition status), and both are by being fixed on the installing plate 10 on the gas pipeline, upper and lower fit together, 2 is pipeline valve, and 3 is the ball valve chamber, and 4 are ball valve chamber lid, 5 (are at the bottom of the ball valve chamber for the steel ball valve, its slightly larger in diameter is in the bore of valve 2), 7 is the timer turn-knob, 8 is the arm of turn-knob, 9 for being set in the following little magnet steel of turn-knob arm, arrow be depicted as gas-flow to.Wherein: the center of valve 2, the centre of sphere of the center of little magnet steel 9, globe valve 5 (comprise dynamically and static), this " three-core " is far away apart from the rotating shaft core of timer 6 etc., that is to say that " three-core " is on " track " of little magnet steel 9 rotations.When the turn-knob 7 of timer was parked in original position, little magnet steel 9 just in time was parked on the valve 2 under its arm.

Installing, when using the utility model device (consulting Figure of description Fig. 1), should make the turning cylinder of the timer 6 in this device be level or,, no matter under moving or quiet situation, be unlikely " overstepping the limit " so as to guaranteeing ball valve 5 horizontal by about 30 ° angle.When using gas-cooker to need regularly again, should be earlier with the turn-knob 7 of timer 6 parts in original position, clockwise direction is threaded to the position of required timing, in this process, turn-knob arm 8, rotate owing to be close to the wall (distance about 1mm) in ball valve chamber, its arm little magnet steel 9 down just attracts and is being with steel Ball valve 5 disengaging valves 2 and falls within the end in ball valve chamber 3.At this moment, valve 2 just is opened, and the fuel cartridge of then just can outwarding winding has been struck sparks.After this, the rotating shaft of timer 6, when counterclockwise returning back to the sidewall in ball valve chamber 3 with turn-knob 7 under self clockwork spring drives, the little magnet steel 9 that its turn-knob arm is 8 times just can attract to be parked in the steel small ball 5 at the bottom of the ball valve chamber and bring to original position (regularly finishing).When small ball 5 during near valve 2, because " guiding " and " promotion " of gas-flow effect, small ball 5 can only be parked in valve 2 places, at this moment, small ball 5 is under the double reaction plus of little magnet steel 9 and gaseous-pressure, just valve 2 is tightly blocked and blocked fuel gas path, stove extinguishes, and has reached the timing automatic purpose of extinguishing gas-cooker.The people closes fuel cartridge with meeting.If the short time, people only needed the original position at timer, counterclockwise rotate timer turn-knob 7 (turning over 60 ° of central angles approximately) because of little magnet steel 9 leaves valve 2 when using gas-cooker not need regularly, small ball 5 can only be back to the end in ball valve chamber 3 by self gravitation.At this moment, valve 2 is opened, and then people's fuel cartridge of just can outwarding winding has been struck sparks.
