Description

Arc lighter with longitudinal multi-arc beam distribution

technical field

The invention relates to an electric arc lighter, in particular to an electric arc lighter with longitudinal multi-arc beam distribution.

Background technique

In the prior art, lighters commonly used by people include electronic lighters, piezoelectric ceramic lighters, and flint friction ignitions. etc., therefore, for the user, there are still problems such as inconvenient use, unsafe and unclean.

In order to solve the existing problems of traditional lighters, an arc type lighter appears in the prior art, such as a kind of arc lighter whose Chinese patent publication number is CN2896052Y (disclosure date: May 2, 2007). Generator, discharge electrode and switch. The input end of the high voltage generator is connected to the battery through a switch, and the output end is connected to the discharge electrode. The high voltage generator is used to provide high voltage and discharge electric energy to the discharge electrode. The discharge electrode is used to generate arc. The electric arc lighter saves the process of filling fuel, is more clean and hygienic when used, and eliminates the unsafe factors of storing inflammable and explosive items at home.

Through retrieval, the following technical improvements occur in the prior art based on the above-mentioned arc lighter:

Chinese Patent Publication No. CN203656980U discloses a multi-fire arc lighter (disclosure date: June 18, 2014), the structure of which includes an arc generating head including an insulating porcelain cup and at least two sets of Arc head, each group of arc head is composed of positive and negative two metal wires or two metal sheets. The problem with this multi-fire arc lighter is that the arcing points of the metal wires that generate arcs from multiple groups of arc heads are located on the same plane, so the arc heating zones formed by them are on the same plane. When lighting a cigarette, in order to make the cigarette ignite as soon as possible, it is necessary to insert the cigarette into the plane of the arc heating zone at an angle that meets the vertical intersection of the cigarette and the plane of the arc heating zone as much as possible, so as to achieve a sufficient intersecting heating area between the two, thereby ensuring cigarette lighting speed and efficiency.

However, in the actual process of lighting cigarettes, consumers are often very random about the angle of lighting. Some like to insert the cigarette head into the cigarette lighter heating area from above, and some like to insert the cigarette head into the lighter from side to side. The cigarette lighting heating area also has the cigarette lighting heating area that likes to insert the cigarette head obliquely downward into the lighter. Therefore, during the use of the multi-fire arc lighter disclosed in the above-mentioned documents, consumers often lose the cigarette due to the unsatisfactory lighting angle. It is impossible to guarantee a sufficient area for lighting cigarettes, which makes the efficiency of lighting cigarettes very poor, and often requires multiple lighting actions to light cigarettes.

For daily necessities such as lighters, it is necessary to strictly limit consumers' cigarette lighting actions to achieve an ideal cigarette lighting effect, which is difficult for consumers to accept and love.
