Abstract
The utility model relates to a needle valve switch with an automatic ignition device. A push rod is arranged in an annular chamber in a turn knob of a needle valve, the outside of a push rod housing is sheathed with a clutch, the front exploring part of the push rod is contacted with a piezoelectric ceram switch in a switch cover, the position of the switch cover is outwards provided with a high voltage electricity transmitting wire, and the other end of the piezoelectric ceramic switch is contacted with an earth wire which is outwards arranged. When the turn knob is turned widdershins, the switch shaft component of an air valve is moved backward, the needle valve is opened; meanwhile, the clutch is operated to depress the piezoelectric ceram switch, the depressed ceram switch is made to generate high voltage, and the synchronous action of the switch and ignition is realized in an ignition zone of a gas device through the function of the electricity transmitting wire.
Description
The utility model relates to a kind of gas appliance, particularly a kind of needle valve switch that has automatic ignition device that is installed on the oil gas combustion vapour apparatus.
At present, what use on products such as used in LPG stove, gas lamp all is needle valve switch, and the switch that it can be used as ventilation uses, and itself does not possess ignition function, and igniter is independent in addition the setting.The problem of being brought is like this: the structure that makes small-sized portable gas tool is not compact and volume becomes big, influences aesthetic appearance simultaneously yet, and, switch and igniting be used having caused of operating respectively being inconvenient to reach easily deflation, problem such as lighting rate is low.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and the needle valve switch that has automatic ignition device of the high lighting rate that carries out simultaneously of a kind of compact conformation being provided, opening and lighting a fire.
The purpose of this utility model is to realize by following technical scheme: put push rod in the annular chamber in the knob of needle-valve, outer cover at pushing rod sleeve is placed with clutch, piezoelectric ceramics switch in push rod preceding visited part and be installed in switch cover contacts, outside the switch cover position, draw high voltage transmission line is arranged, the other end of electroceramics switch contacts with the earth connection that draws outward, when rotating counterclockwise knob, move behind the switch shaft assembly of air valve, needle-valve is opened, at the same time, clutch operating also pushes the piezoelectric ceramics switch, makes the ceramic switch of pressurized produce high pressure and acts on the seed region of combustion gas tool by power transmission line, realizes the synchronization action of switch and igniting.
Therefore: remarkable result of the present utility model is:
1. the unlatching of switch is carried out synchronously with igniting, has characteristics easy and simple to handle, that lighting rate is high, safe and reliable.
2. igniter is located at the needle-valve group, makes burner compact conformation, good looking appearance.
Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof:
Fig. 1 is a section of structure of the present utility model.
Fig. 2 is the partial sectional view that Fig. 1 overlooks direction.
Below in conjunction with accompanying drawing 1-2 concrete structure of the present utility model is described in detail.
The utility model has a supporting disk 7 that fastens with the fuel cartridge mouth, supporting disk 7 is connected with switch case 2, inlet channel 3 is arranged at switch case 2 bottoms, outgassing nozzle 1 is arranged at top, laterally twist and be placed with a switch shaft assembly 4 at valve channel place between inlet channel 3 and outgassing nozzle 1, the outer spy end of switch shaft assembly 4 is connected with knob 8, be provided with a position-limitting pin 6 in switch shaft assembly 4 stage casings, at switch case 2 top ladle covers switch cover 5 is arranged, it is characterized in that: in the annular groove 81 of knob 8, be set with push rod 11, the preceding spy part 111 of push rod 11 contacts with piezoelectric ceramics switch 12 in being housed in switch cover 5, the other end of piezoelectric ceramics switch 12 is provided with an outer ground strip 10 of drawing, outer drawing connects to have high voltage transmission line 13 on the piezoelectric ceramics switch 12, and cover is placed with clutch 8 in the knob annular groove 81 of the outside of push rod 11.Referring to Fig. 1 and Fig. 2
Architectural feature of the present utility model also is:
The annular casing at push rod 11 rear portions and the inner cylinder 82 of knob 8 be fit mutually, and visiting before all sides of annular casing part has one to visit part 111 before L shaped, visits part 111 before L shaped and contacts with piezoelectric ceramics switch 12 1 ends in being housed in switch cover 8 front sides.Referring to Fig. 2
The utility model operation principle is summarized as follows
Air valve is opened when knob 8 counterclockwise rotates, and drives clutch 9 at the same time and pushes piezoelectric ceramics switch 12 by push rod 11, and the piezoelectric ceramics switch of pressurized produces high pressure and realizes igniting by the seed region that power transmission line 13 acts on the combustion gas tool.
