Abstract

The utility model provides an automatic shut-off valve of gas cooker, belonging to the technical field of the valve for solving the problem of the automatic cutout of the gas range. The automatic shut-off valve of gas cooker is composed of a cover body, an air valve fixed in the cover body and a timer. The handle rod of the timer is a driving shaft, an incomplete gear intermittent drive mechanism is arranged between the driven shaft and the driving shaft. The timer of the utility model can randomly set the time in allowable range; automatically cut-off the air source when times up, and which is provided with a final protective screen for the gas range. The automatic shut-off valve of gas cooker makes the gas range more safety in use, and makes the operator saved lots of time during the cook, which is a good ideal matching appliance for safely using the gas range.

Description

Gas cooker closes air valve automatically

Technical field

The utility model relates to a kind of gas cooker and closes air valve automatically, belongs to valve technology field.

Background technique

When being engaged in the cooking activity with gas cooker, its ignition switch all opens and closes on demand at any time by the operator, but in daily life, tend to run into various unexpected thing and take place, if the kitchen is forgetful for some reason, it is when using gas cooker, unavoidable because of forgetting that Guan Huoer has an accident, the lighter damages cooker, and weight person causes fire, even brings disaster to neighbours.So the deficiency of this common ignition switch is conspicuous.

Summary of the invention

The utility model is used to overcome the defective of prior art and provides a kind of gas cooker to close air valve automatically, and this air valve timing automatic as required cuts off source of the gas.

It is as follows to address the above problem the technological scheme that is adopted:

A kind of gas cooker closes air valve automatically, it comprises air valve 3 and timer 8 in cover body 5, the fixed enclosure 5, the valve rod of air valve 3 is a driven axle 11, and the handlebar of timer 8 is a driving shaft 10, is provided with the partial gear intermittent drive mechanism between driven axle 11 and the driving shaft 10.

Above-mentioned gas cooker closes air valve automatically, and the fan-shaped angle α of the active partial gear 6 of said partial gear intermittent drive mechanism is 80～90 °, and initiatively the gear parameter of partial gear 6 is identical with the gear parameter of driven gear.

Above-mentioned gas cooker closes air valve automatically, and the driven gear of said partial gear intermittent drive mechanism is complete gear 4, and driven gear also can be partial gear, and at this moment, its fan-shaped angle is 95～100 °.

Above-mentioned gas cooker closes air valve automatically, the driving shaft 10 of said timer 8 is provided with cam 15, the push rod 12 of cam 15 is fixed in the swing arm 16, the housing of swing arm 16 1 ends and timer 8 is hinged, push rod 12 contacts away from a contact point arm 13 in two contact point arms 13,14 of an end of cam 15 and an electric switch, two contact point arms 13,14 are fixed on the housing of timer 8, described two trigger switches that the contact is an alarm.

The gas cooker that provides according to the utility model closes air valve automatically, be provided with the partial gear indexing mechanism between handlebar because of its valve rod and a timer, when using the gas cooker that this valve is installed to be engaged in the cooking activity, can be in the scope (as 60 minutes) that timer allows any set time, then, the utility model can cut off source of the gas automatically, thereby is provided with last safety curtain one for gas cooker.It is safer reliable to make gas cooker use, and energy saving also can make the operator save a large amount of cooking time, and it is the desirable supporting valve of various gas cooker safe handlings.

Specific embodiments

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Referring to accompanying drawing, formation of the present utility model comprises cover body 5, is fixed in air valve 3 and timer 8 in the cover body 5, and the suction port place of air valve 3 can be provided with hose coupling 2 according to user's needs, also can select other pipeline connecting mode for use, connects as rigid conduit.Air valve 3 shown in Fig. 1 is screwed on the base plate of cover body 5, and timer 8 is screwed on the set pillar 1 of base plate.Cover body 5 and base plate thereof can adopt metal material or plastic material etc.The valve rod of air valve 3 is a driven axle 11, and the handlebar of timer 8 is a driving shaft 10, is provided with the partial gear intermittent drive mechanism therebetween.Fig. 1, embodiment illustrated in fig. 3 in, in having the gear mechanism of intermittently-driving, initiatively the fan-shaped angle of partial gear 6 is 80～90 °, the relevant parameter of the driven gear on the other technologies parameter of gear and the driven axle 11 is identical, promptly initiatively partial gear 6 can be considered with driven gear be identical a pair of gear, just one of them gear is removed about tooth of about 3/4ths and the tooth sector that forms.Driven gear shown in the figure is complete gear 4.In addition, because of the keying of air valve 3 only needs the turn in 0～90 ° of scope of its valve rod, so the driven gear on the driven axle 11 also can be tooth sector, just its fan-shaped angle should for example can be selected in 95～100 ° scope greater than the fan-shaped angle of active partial gear 6.In order to remind the user after then, this valve also can be set up a cover alarm device (because of the warning device application is very extensive, having various musicalss can supply to select for use, so the utility model no longer draws).In Fig. 4, two contact point arms 13,14 of alarm device electric switch are fixed on the housing of timer 8, are provided with cam 15 on the handle shaft (being driving shaft 8) of timer, like this, will reach before closing gas about one minute at timer, cam 15 promotes contact 13 by push rod 12 and draws close to another contact point arm 14, makes power turn-on, warning device toot sound one minute, afterwards, when being timed to, air valve is closed, and stops to report to the police.

The utility model when mounted, the hose coupling 2 usefulness flexible pipes at the inlet, outlet place of air valve 3 can be serially connected between source of the gas and the gas cooker, if will use, the handle 7 of turn timer 8 at first along clockwise direction, scale according to the dial on the cover body 59 is chosen timing, and the ignition switch of opening then on the kitchen range gets final product.Then, though the ignition switch on the kitchen range still is in opening state, the utility model cuts off source of the gas.Timing range can be set as required, generally can set in 3～60 minutes.

Intermittent drive mechanism is action like this: timer turns clockwise, the fan-shaped angle of the active partial gear 6 on the handle shaft 10 has only 85～90 °, so, partial gear 6 can only drive the driven gear 4 that is engaged with and be rotated counterclockwise 85～90 °, after 90～180 ° of scopes in this gear pair be in separated state, promptly partial gear 6 is in idling conditions in 90～180 ° of scopes.When partial gear 6 returns, still be in idling conditions in 90～180 ° scope, afterwards, two gears mesh again, and the valve rod 11 that drives air valve 3 rotates 85～90 ° along clockwise direction in the corresponding time, and air valve 3 is closed, and source of the gas is cut off.
