Abstract

The utility model relates to a gas burning timer. The utility model is characterized in that a valve 3 at a gas inlet 1 is propped tightly by a spring 2, the top end of the valve 3 is provided with a ball 4 of which the outer surface is tightly matched with the outer edge of a rotary wheel 7, and the rotary wheel 7 is connected with a mechanical timer 9 by a control rotating shaft 10. The utility model has the advantages of simple and reasonable structure and convenient operation. A gas range can be used for boiling, stewing, decocting, etc. for a long time and can automatically close without being watched by any person. The utility model has timing and ordinary opening and closing functions, the timing time can be adjusted within two hours.

Description

Gas burning timer

The utility model is a kind of combustion gas timer, relates to the time switch technology of gas furnace.

Existing gas kitchen ranges does not all have timing means, brings some inconvenience to use, and the operation of long periods such as especially boiling, stew, endure can't be carried out under unmanned nurse.

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of combustion gas timer that makes gas kitchen ranges have the time switch function is provided.

The purpose of this utility model can reach by following measure: there is a valve at the gas inlet place by spring top clamping, the outer rim tight connecting of valve tip one outer surface of spheroid and runner, and runner is connected with mechanical timer by the control rotating shaft.

The purpose of this utility model can also reach by following measure: have an arc gap on the outer rim of runner, outer surface of spheroid and gap surface can tight connectings.Control rotating shaft one end has seal shaft to be connected with runner with spring.The control rotating shaft is connected with the clockwork spring of mechanical timer.

Accompanying drawing is the utility model structure chart.

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

As shown in the figure: air inlet 1 inner conical valve 3 is held out against by spring 2, top one steel ball 4 is pressed on the outer rim of runner 7, open an arc gap on the outer rim of runner 7, when steel ball 4 falls into gap, valve 3 is subjected to spring 2 to be pushed to the limes superiors position, be in closed condition, this moment, runner 7 was connected with mechanical timer 9 with control rotating shaft 10 by a cone seal axle 6 corresponding to the nought state of timer 9.When rotating shaft 10 is turned over a certain angle clockwise, tighten the clockwork spring of timer 9, the outer rim of runner 7 is extrapolated with steel ball 4, thereby conical valve 3 is opened, and at this moment gas is by air inlet 1, and conical valve 3 enters gas outlet 5.Under the clockwork spring effect of timer 9, runner 7 will be with revolution at a slow speed, and up to the zero-bit position of timer, steel ball 4 falls into the gap on the runner 7, and conical valve 3 is in normally off, thereby the timing that has realized valve is closed.Regularly service time the longest reaching more than 2 hours.

When rotating shaft 10 when zero position is counterclockwise changeed an angle, conical valve 3 is opened, but this moment, the timer clockwork spring did not tighten, timer does not turn round, and realizes the normal open of conical valve 3.Cone seal axle 6 plays sealing function by spring 11 tensions, makes gas be unlikely to leak to timer 9 along rotating shaft 7 on one side.

The new shape of this practicality is compared prior art and is had following advantage:

Simple and reasonable for structure, easy to use, gas kitchen ranges can use in the lower long period of unmanned nurse, as boil, stew, endure etc., autoshutdown. Have regularly and two kinds of functions of ordinary tap, timing at two hours with interior adjustable.

Claims

1, a kind of combustion gas timer is characterized in that valve 3 is held out against by spring 2 in the air inlet 1, and there is a spheroid 4 on valve 3 tops, the outer rim tight connecting of its outer surface and runner 7, and runner 7 is connected with mechanical timer 9 by control rotating shaft 10.

2, combustion gas timer as claimed in claim 1 is characterized in that on the outer rim of runner 7 an arc gap being arranged, and spheroid 4 outer surfaces and gap surface can tight connectings.
