Describe the preferred of the timing automatic flame-out lighter of the utility model flame controllable type in detail below in conjunction with accompanying drawing

Embodiment.

Figure 1 shows that the timing automatic flame-out lighter of the utility model flame controllable type.As shown in Figure 1, a blast tube housing 100 is fixedly mounted in the plastic shell of lighter.One hollow sleeve 200 is contained in the upper cavity of blast tube housing 100, and hollow sleeve 200 can move up and down in blast tube housing 100.Fixedly mount a fuel gas pipe 400 in the blast tube lower part of frame, for example can realize by being threaded.Blast tube housing 100, hollow sleeve 200 and flue 400 have been formed the fuel gas feed path of lighter.

As illustrated in fig. 1 and 2, a check valve 1 is installed in the lower cavity of blast tube housing 100.Check valve 1 is made up of a spool 11, a sealing ring 12 and a spring 13, is bearing on the interior shoulder of flue 400.

One passage base 2 is installed at the top of spool 11.Passage base 2 has a centre bore 21.The lower surface of passage base 2 has some radial slots 22.Centre bore 21 communicates with radial slot 22.Centre bore 21 is divided into two sections, and the aperture, bottom is less, is the passage of fuel gas, and the aperture, top is bigger, and the device 300 of control flame height is installed, and in this upper hole, has negative thread on the wall surface of the hole.

As shown in Figure 2, the device 300 of control flame height comprises that the bottom is the flexible pressure regulation sheet 301 that filters of a cover, for example a cover foam-rubber cushion top is a control screw 302 that has several axial grooves on flank, the pin thread of control screw and the female thread in the passage centre hole of base, have with tightening tool is complementary at the end face of control screw and to tighten groove or to tighten plush copper, shape can be quadrangle, hexagon etc.

One voltage stabilizing cover 3 is sleeved on the top of passage base 2.Between the lower end of the lower flange of passage base 2 and voltage stabilizing cover 3, a sealing ring 8 is installed.

Hollow sleeve 200 is sleeved on the top of voltage stabilizing cover 3.Decompression sheet 6 on once reduce pressure sheet 4, the dottle pin 5 and is housed in the lower cavity of hollow sleeve 200.The sheet 4 that reduces pressure down is bearing on the top of voltage stabilizing cover 3.Dottle pin 5 under reduce pressure sheet 4 and on the decompression sheet 6 between.Between the empty wall inwall in bottom of sheet 4 and upward reduce pressure sheet 6 and the hollow sleeve 200 of reducing pressure down less gap is arranged, this gap has the expenditure and pressure effect to the fuel gas that is passed through.Several axial grooves are arranged on the face of cylinder of dottle pin 5, play shunting action.

An one voltage stabilizing check valve 7 and a sleeve 15 are contained in the middle and upper part cavity of hollow sleeve 200.Voltage stabilizing check valve 7 is made up of a spool 71, a sealing ring 72 and a spring 73.The spring of voltage stabilizing check valve 7 is positioned at the blind hole of sleeve 15.Between the cavity inner surface of the outer surface of sleeve 15 and hollow sleeve 200 certain clearance is arranged, fuel gas can therefrom pass.

The sparking process of the timing automatic flame-out lighter of the utility model flame controllable type is as follows:

When striking sparks operation, sparking actuating mechanism (existing) applies a downward power for hollow sleeve 200, and it is moved down.Voltage stabilizing cover 3 and passage base 2 move down with hollow sleeve 200, apply a downward power for the spool 11 of check valve 1.Under the effect of downward power, the spool 11 of check valve 1 overcomes the elastic force that spring 13 makes progress and moves down, and check valve 1 is opened.The sparking end of operation, the sparking downward power that actuating mechanism applied disappears, and hollow sleeve 200 moves up under the effect of a back-moving spring (existing) power and gets back to the origin-location.At this moment, the spool 11 of check valve 1 is also closed under the effect of the elastic force of spring 13 automatically.Just from check valve 1 being opened in the time interval that check valve 1 closes automatically, a certain amount of band pressed gas has entered in the fuel gas feed path in check valve 1 downstream.This part fuel gas flows through the radial slot 22 and the centre bore 21 of passage base 2, and what enter the control flame height then adorns 300, again through decompression sheet 4 and last decompression sheet 6 reduce pressure down.The fuel gas of this moment still has certain pressure, can overcome the elastic force of the spring 73 of voltage stabilizing check valve 7, and check valve 7 is opened automatically, flows to the outlet of fuel gas feed path, realizes sparking.When the pressure of the fuel gas in the fuel gas feed path in check valve 1 downstream was lower than certain value, check valve 7 was closed automatically, cut off fuel gas and supplied with, thereby make the rapid auto extinguishing of lighter flame.

Because this lighter has the device 300 of control flame height, by regulating the position of control screw 302 in the centre bore 21 of passage base 2, make the flexible compression that pressure regulation sheet 301 is subjected in various degree of filtering, change its air penetrability, thereby the throughput of control fuel gas finally reaches the purpose of controlling flame height.
