【Example】

The embodiments of the disposable gas lighter of the present invention are divided into the following three configurations and will be explained in detail. explain.

0010 (1) Gas guide device This invention removes the sponge suction rod of conventional disposable gas lighters, Thus, the cost of this part and installation cost are saved.

[0011] As shown in Figure 4, the disposable gas lighter of the present invention directly uses plastic gas. Two clamping walls 1102 are provided on the inner wall 1101 for reinforcing walls in the tank 11, and It extends to the gas outlet hole 1103. There is a capillary between these two clamping walls 1102. A pipe groove 1104 (see Figure 4) is formed, and the groove width allows the liquid gas to flow through its surface tension. The gas can rise to the gas outlet hole 1103 by capillary action within the capillary groove 1104. It has an appropriate width that allows it to be used.

0012 Compared to traditional disposable gas lighters, the capillary groove structure of the present invention requires no installation. It improves the ability to raise liquid gas and prevents parts from breaking down. can simplify assembly and reduce assembly and installation costs.

[0013] (2) Gas regulator This gas regulating device is divided into (A) gas regulating mechanism and (B) gas control valve. . Next, each will be explained.

[0014] (A) Gas adjustment device As shown in FIG. 3, the disposable gas lighter according to the present invention includes a gas tank 11 and an ignition stand. The seat 12 and the valve body pedestal 13 are simplified and injection molded as a single unit using plastic material. An open opening 1105 is formed at the bottom of the gas tank 11 to fill the liquid gas. After completing the filling work, attach the bottom cover 14 to the opening 1105 of the gas tank 11 using an ultrasonic welder. Weld with.

[0015] The gas outlet hole 1103 of the gas tank 11 is connected to the valve body housing hole 130 of the valve body pedestal 13. 1, and the bottom 1302 of the receiving hole 1301 has a slot 130 as shown in FIG. 3 is opened, and this slot 1303 crosses the gas outlet hole 1103, and the groove hole 1303 crosses the gas outlet hole 1103. A metallic double-head lid body 15 is arranged inside the bottom part 1302, and this metallic double-head lid body 15 is arranged inside the bottom part 1302. The cylindrical body 1501 of the pad cover body 15 is slightly smaller than the inner diameter of the accommodation hole, and there is a suitable space between the two. A gap 1502 is maintained, and the lower head portion 15 of the metal double head lid body 15 is 03 extends into the gas outlet hole 1103, so that the head part 1503 and the gas outlet An appropriate gap 1504 is maintained between the hole 1103 and the hole 1103. The metal double head The upper head portion 1505 of the lid body 15 is first a circular spongy throttle washer. 16 and further extends into the valve hole 1708 at the bottom of the gas control valve 17; Similarly, a suitable gap 1 is provided between the upper head portion 1505 and its valve hole 1708. It holds 506. The width of the gap 1506 is determined by the surface tension of the liquid gas. It has an appropriate width that allows it to rise within the capillary action based on capillary action.

[0016] Since the structure is as described above, liquid gas flows from the capillary groove 1104 due to capillary phenomenon. The gas flows up to the gas outlet hole 1103 and passes through the slot 1303 along the gap 1504. It enters the gap 1502 and then penetrates into the spongy throttle washer 16 to form a gap. It leads to gap 1506. Then, when the gas nozzle 18 is opened, the liquid gas is vaporized. Escape. The above is the gas adjustment mechanism of this invention, which is similar to the conventional disposable gas lighter. In comparison, many parts are simplified.

[0019] Normally, after completing the lighter flame adjustment work, be sure to check the rotation range of the gas control valve 17. The maximum and minimum flame levels are determined in advance. Therefore, the conventional disposable plus Even if the valve body bolt of a Chic gas lighter is made of plastic, its thread line They are all somewhat different, so even under the same gas flow rate, each valve body The ratchet wheels of the engine are not in nearly the same angular position, so the flame adjustment lever 70 1, when the ratchet hole of the flame adjustment lever and the ratchet of the valve body bolt This is the first time that each tooth can fit together with the cut ring. Misalignment of the septal teeth like this The difference is approximately 20 degrees, and the error in rotating the valve body bolt by 20 degrees is due to the gas flow rate. A large difference occurs, and the flame height setting range cannot be determined accurately.

[0020] In order to avoid the above-mentioned situation, the present invention eliminates the conventional configuration of the flame adjustment lever. ratchet teeth 17 on the circumference of the large diameter disc 1704 of the direct gas control valve 17. 05 so that the size of the flame can be adjusted by directly rotating the ratchet teeth. I have to. Moreover, a ring piece 1706 is placed on the top of the disk to adjust the flame height. After completing the work, use an ultrasonic cutter to cut a size approximately 9 on the ring piece 1706.

The injection port 1802 is provided in the center of the gas nozzle 18, and the cylindrical body of the gas nozzle 18 is The diameter of the cylindrical body is inwardly reduced at an appropriate location at the bottom of 1803 to form the fitting cylindrical body part 180. 5, a long hole 1804 is cut out in the fitting cylinder part 1805, and a long hole 1804 is cut out in the fitting cylinder part 1805. 05, push the closing rubber lid 1806 from the bottom, and The length of the shaft pin 1807 is shorter than the elongated hole 1804, and the fitting cylinder portion 1805 has a closing gong. When the lid body 1806 is fitted, there is a gap 1 between the elongated hole 1804 and the shaft pin 1807. 808 is formed through which gas can enter the injection port 1802. I try to do that.

[0022] The gas nozzle 18 is arranged in the accommodation hole 1707 of the gas control valve 17, and its cylindrical body The diameter of the hole 1803 is configured to be slightly smaller than the diameter of the accommodation hole 1707, and both A small gap 1809 is formed between the fitting cylinder portion 1805 and the receiving hole 1707. A large gap 1810 is formed in between, and the closing rubber lid body 1806 is located at the bottom of the accommodation hole 1707. Valve hole 1708 is closed. The gas nozzle 18 of the present invention is a conventional disposable gas nozzle. The metal spring used in the slitter to block the gas has been eliminated, and the pressure plate 20 has a plastic leaf spring integrally injection-molded with plastic below it. 2001, the pressure plate 20 is pushed up by the elasticity of the plastic leaf spring 2001. , the gas nozzle 18 is held by the clamping plate 2002 at the front end of the pressing plate according to the lever principle. The neck portion 1801 of the gas cylinder is held and compressed downward to maintain the gas closed state.

[0023] In the configuration of the present invention, the gas nozzle 18 is It rises, releases the valve hole through the closing rubber lid 1806, and vaporizes. The gas enters into the large gap 1810 through the valve hole 1708. At this time, Gas is blocked by atmospheric pressure and cannot enter into the small gap 1809, and the elongated hole 18 The injection port 1802 enters through the gap 1808 of 04, and the gas is ejected from above the nozzle. do.
