Description
Technical field
The present invention relates to a kind of timing means, especially a kind of Household gas pipeline intervalometer.
Background technology
Huge numbers of families have been come in combustion gas, are that the life of people brings great convenience, if improper use also brings along
Disaster, if the valve closing of gas-cooker is tight, the food soup that boiling on gas-cooker or boiled water overflow and put flare out by water
Shi Douhui causes gas leakage, and people indoors easily causes combustion gas to be poisoned, and, when cooking, if people does not exist for a long time
The side of gas-cooker, food will be boiled paste, of course for overcome occur because nobody looks after food boil paste or soup boiling
Overflow the phenomenon putting flare out by water, occur in that the various intervalometers controlling combustion gas to open and close on the market, carried out by intervalometer
Regularly, after the time reaching regulation, the output of intervalometer meeting automatic self-closing gas pipe gas.
China Patent Publication No. discloses a kind of timer for gas stove for cn2911483y, and this timer for gas stove is by giving vent to anger
Joint, mechanical timer, connection flexible pipe, axle, rotating disk, pole and air inlet switch composition, air inlet switch, by connecting leg, is arranged on this company
The end cap of pipe one end, is arranged on the plug of the connecting leg other end and is sleeved on spring on this connecting leg, this timer for gas stove is opened
Qi Shi, after setting time reserved by mechanical timer, is swung by driven by rotary disc pole, connecting leg is under the drive of pole to a sidesway
Dynamic, now, plug is separated with the opening of air inlet switch, and the air inlet on connecting leg is connected with being connected flexible pipe, and coal gas enters into coal
In gas kitchen, only after the time that mechanical timer sets covers i.e. rotating disk reset, rotating disk could carry this timer for gas stove
Dynamic pole swings thus realizing the purpose that plug seals air inlet switch opening, if in the midway of timing, gas range boils
The food soup of boiling or boiled water overflow when putting flare out by water, and because rotating disk does not reset, coal gas is still within on-state, will
Cause gas leak, easily cause carbon monoxide poisoning and the danger of blast, and this timer for gas stove only merely passes through one
Individual plug, to close coal gas, when sealing effectiveness is bad due to long use for plug, if checking repairing not in time, also can
The phenomenon of gas leak occurs, protection is not good.
China Patent Publication No. discloses a kind of timer for gas stove for cn2921638y, this timer for gas stove with
Disclosed in cn2911483y, a kind of timer for gas stove structure is roughly the same, if in the midway of timing, gas range boils
The food soup of boiling or boiled water overflow when putting flare out by water, and because rotating disk does not reset, coal gas is still within on-state, will
Cause gas leak, easily cause carbon monoxide poisoning and the danger of blast, and this timer for gas stove only merely passes through one
The close contact of individual closure ring and bulge loop closing coal gas, when block ring due to long using and when sealing effectiveness is bad,
If checking repairing not in time, the phenomenon of gas leak also occurs, protection is not good.
Content of the invention
The invention aims to the defect existing for Gas range timer in solution prior art, one kind is provided to have

Mouth 12 and the second sealed mouth 13 respectively with the first connector 4 and the second connector 5 tight connecting, inlet channel 2 and outlet passageway 3
It is in dissengaged positions；
When this Household gas pipeline intervalometer is opened, turn knob 33, and control need by the scale on dial plate 34
Time to be heated, after intervalometer 7 work, cam 11 rotates together with knob 33, now, card from cam 11 for the shifting block 29
Abjection (cam now resets in the presence of the gear train 37 of intervalometer at leisure) in groove 28, after abjection, shifting block 29 carries
Arm-tie 30 to swing aside, arm-tie 30 rearward presses block 31, block 31 drives hook block 32 to tilt, and now, hooking block 32 must
Lower sealing plate 10 is driven to move up, now, the first sealed mouth 12 of lower sealing plate 10 lower surface and the second sealed mouth 13 are respectively
Separate with the first connector 4 and the second connector 5, the outer wall of the lower surface of lower sealing plate 10 and inlet channel 2 and outlet passageway 3
Between form the transition cavity 14 that inlet channel 2 is connected with outlet passageway 3, inlet channel 2 and outlet passageway 3 pass through first even
Interface 4, the second connector 5 and transition cavity 14 are in connected state, during moving on lower sealing plate 10, with lower sealing
The pull bar 21 that plate 10 is fixedly connected top by the sliding contact with the top cap 18 of construction of switch, drive the push rod of construction of switch
16 have done a flexible stroke, and when push rod 16 stretches out, ball 23 intimate contact therewith is pushed up by the sleeve 17 of push rod 16 end
Open, now extraneous air supply opening 15 has been also at on-state with inlet channel 2, combustion gas directly from extraneous air supply opening 15 enter into into
Gas passage 2 simultaneously enters into 14 adapter cavity from the first connector 4 of inlet channel 2, and the combustion gas in adapter cavity 14 is along second
Connector 5 enters directly in outlet passageway 3 and burns in gas-cooker, after burning a period of time, when intervalometer 7 is determined
Between when reaching, cam 11 has reset to the initial position of intervalometer unlatching, and shifting block 29 is returned in the draw-in groove 28 of cam 11 again,
Arm-tie 30 is separated with block 31, hooks block 32 and again revert to vertical state, hooks block 32 and does not apply any drawing to lower sealing plate 10
Power, now, lower sealing plate 10, in the presence of the gravity of itself and the back-moving spring 36 of resetting structure, voluntarily moves down,
Until lower surface and the inlet channel 2 of lower sealing plate 10 and the outer wall of outlet passageway 3 are in close contact, the of lower sealing plate lower surface
One sealed mouth 12 and the second sealed mouth 13 respectively with the first connector 4 and the second connector 5 tight connecting till, now, air inlet
Passage 2 and outlet passageway 3 are in dissengaged positions again.
This Household gas pipeline intervalometer is by the first sealed mouth 12 on lower sealing plate 10 and the second sealed mouth 13 difference
Unlatching with the first connector 4 and the second connector 5 and closure controlling connection and the cut-out of inlet channel 2 and outlet passageway 3,
And, when inlet channel 2 and outlet passageway 3 are in dissengaged positions, lower sealing plate 10 and inlet channel 2 and outlet passageway 3
Outer wall is in close contact, and transition cavity 14 disappears, and serves the effect of positive confinement, and the effect of fuel gas shutoff is very good, will not go out
The phenomenon of existing gas leakage；When moving on lower sealing plate 10, pull bar 21 on lower sealing plate 10 drives the push rod 16 of construction of switch to one
Side ejects ball 23, is separated with sleeve 17 by ball 23 and reaches the purpose that extraneous air supply opening 15 is connected with inlet channel 2,
When intervalometer 7 timing has not timed out and flare and put out by water, because now inlet channel 2 and outlet passageway 3 are still located
In the state connected, the combustion gas of leakage creates enough air pressure and ball 23 is expressed to the opening of sleeve 17 tight therewith
Contact, it is achieved thereby that automatically cutting off effect of combustion gas, when timing has not timed out and flare is put out by water, is also not in leakage
The risk of gas, protection is good.
