Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an improvement of a tabletop gas lighter.

(Prior Art) Generally, tabletop gas lighters have a gas tank and an ignition operating mechanism housed in a decorative case.

For example, a cosmetic case having a storage section that is open at the top, and a case that is stored in the storage section of the cosmetic case,
A windshield cap that covers the upper surface of the gas ejection nozzle and an ignition operator that operates the piezoelectric unit in the pushing direction are provided adjacent to each other on the top end surface, and the gas ejection nozzle is activated by a series of pushing operations of the ignition operator. The ignition operation mechanism, which is operated to start blowing out gas and actuate the ignition means to generate a spark and ignite the gas, is supported by an intermediate case and housed in a decorative case.

In addition, a cylindrical ignition operator is inserted into the outer periphery of a cylindrical case housing a gas tank with a piezoelectric unit and a combustion valve inside, and the ignition operator is moved up and down along the cylindrical case. Therefore, in a tabletop lighter that operates a piezoelectric unit and a combustion valve, a resilient locking member having a hook at the upper end is spaced apart from the outer surface of the cosmetic case while standing upright in the axial direction. There was a tabletop gas lighter in which a locking hole into which a locking part of a locking member was inserted was formed in the ignition operator (Utility Model No. 55-1983).
(Refer to Publication No. 80670).

(Problem that the invention aims to solve) However, in such a structure, a series of ignition operation mechanisms including the gas jet nozzle are housed in the enclosed storage area, and the storage area can only be opened from above. This, together with the fact that the gas lighter was not properly ignited, caused problems such as poor air intake within the storage compartment and poor ignitability of the gas lighter.

In addition, with the above structure, vaporized gas tends to accumulate in the storage part when it is not ignited, so there is a risk of explosion when it is re-ignited, which can lead to accidents such as burns and fire. Ta.

Furthermore, in the case of the tabletop gas lighter disclosed in Japanese Utility Model Application Publication No. 55-80670, the locking hole provided on the side of the ignition operator allows the ignition operator to be pushed in during the ignition operation.
Since it is buried and blocked within the protective case, it no longer functions as a ventilation hole, and even more so since the ignition operator is fitted to close the entire opening of the cosmetic case. When the ignition button is pushed in, the air inside the cosmetic case is instantly compressed, and the locking hole is blocked, so the compressed air cannot come out from below, causing backflow. The jet of air prevents discharge ignition at the nozzle, leading to ignition errors and so-called extinction.

This invention was made in view of the above-mentioned problems, and the air inside the cosmetic case that is compressed downward when the ignition operator is pushed in is absorbed into the hollow compartment, preventing it from flowing back toward the zenith. When ignited, sufficient air intake from the hollow compartment is ensured, improving ignitability, and when unignited, vaporized gas escapes toward the hollow compartment to eliminate the accumulation of vaporized gas. The purpose of this invention is to provide a tabletop gas lighter that can prevent the above.

(Means for Solving the Problems) In view of the above-mentioned problems, the gist of the present invention in order to achieve the intended purpose is to provide a cosmetic case having a storage section with an upper opening, and the cosmetic case. A gas tank, a gas jet nozzle, an ignition operation mechanism such as a piezoelectric unit, etc., are housed in the storage section via an intermediate case, and a through hole for ventilation is bored in the inner wall surface of the storage section. In the desk gas lighter, a heat-resistant plate is attached to the upper end to surround the periphery of the opening, and a plate-like display body for displaying a name, etc. is detachably attached to the outer surface of the cosmetic case. The case includes a hollow compartment adjacent to the storage portion and whose zenith is closed, and
A gas induction opening is bored in the zenith surface of the hollow compartment and extends to the boundary wall surface with the storage section, and the through hole is formed so as to communicate with the gas induction opening to provide a common opening for both chambers. The table-top gas lighter has a gas combustion section facing near the tip of the gas ejection nozzle, and a notch provided in the heat-resistant plate corresponding to the opening to communicate the gas combustion section with the hollow compartment.

(Function) In the tabletop gas lighter of the present invention configured as described above, the cosmetic case is provided with a hollow compartment adjacent to the storage portion and whose zenith is closed, and the storage compartment is provided on the zenith surface of the hollow compartment. A gas guide opening is bored that faces the boundary wall surface between the chamber and the gas guide opening, and the through hole is formed so as to communicate with the gas guide opening, so that a common opening for both chambers is provided near the tip of the gas jet nozzle. In addition, by providing a notch in the heat-resistant plate corresponding to the opening, when the ignition operator is pushed into the cosmetic case, the air inside the case body is compressed and the air in the case body is compressed downward. Even if the compressed air is jetted toward the zenith, the compressed air will be absorbed toward the hollow compartment, and a backflow toward the zenith will be prevented.

Moreover, when ignited, sufficient air intake from the hollow compartment is ensured, and when unignited,
The vaporized gas is allowed to escape from the combustion section to the hollow compartment through the opening, thereby preventing accumulation of vaporized gas within the storage section, particularly within the combustion section surrounded by the windshield.
