Description

Replaceable hydrogen source storage box for lighter and lighter comprising same

Technical Field

The utility model relates to a lighter technical field, concretely relates to a lighter that is used for removable hydrogen source of lighter to store box and includes it.

Background

Lighters are very common ignition devices in daily life. The main components of a conventional lighter are a firing mechanism and a gas tank. When the ignition mechanism acts, the gas is ignited by the erupting sparks. The lighter can be generally classified into a flint wheel lighter, a piezoelectric ceramic lighter, a magnetic induction lighter, etc. according to the characteristics of the ignition mechanism. The conventional lighter usually uses fuel oil or gas as energy, and generates waste gas during combustion, which is not favorable for environmental protection.

Scientists have been exploring the possibility of using hydrogen as a fuel. At normal temperature and pressure, hydrogen is a gas which is extremely easy to burn, colorless, transparent, odorless and tasteless and is insoluble in water. The calorific value of hydrogen combustion is higher than that of various fuels. The heat released by combustion per kg of hydrogen was determined to be 1.4 x 10^8J, which is more than 3 times the heat value of petroleum. Therefore, it has the advantages of small storage volume, large carrying capacity and long stroke. In addition, hydrogen is the cleanest fuel, and the combustion product of hydrogen is water, so that the environment cannot be polluted. However, it is not easy to store, transport and put into practical use hydrogen gas safely, and it is light in weight, has a fast diffusion speed and is very combustible.

There is also a continuing attempt in the lighter field to use hydrogen as an environmentally friendly energy source. However, hydrogen gas is difficult to be applied in large quantities due to its objective characteristics of being difficult to store and flammable and explosive.

Therefore, there is a need for a new lighter that is environmentally friendly to solve the above problems.

In some specific embodiments, material in the water tank 120 may be added. Specifically, the tank body is provided with a water filling port 121, and a material can be added into the tank body 122 through the water filling port 121.

The replaceable hydrogen source storage cartridge 130 comprises: a cartridge 131 and a solid hydrogen storage material 135, the solid hydrogen storage material 135 being disposed inside the cartridge 131. The cartridge body 131 includes: an injection port 132, a hydrogen outlet 133, and a barrier 134. The injection port 132 and the hydrogen outlet 133 are respectively arranged on the box body 131 and are mutually communicated, the interlayer 134 is positioned inside the box body 131 and divides the inside of the box body 131 into at least two storage areas, and the at least two storage areas are mutually communicated with the injection port 132 and the hydrogen outlet 133.

In some embodiments, after the material in the water tank 120 flows into the replaceable hydrogen source storage box 130 through the filling opening 132 of the replaceable hydrogen source storage box 130, the material reacts with the solid hydrogen storage material 135 in the replaceable hydrogen source storage box 130 to generate hydrogen gas. Then, the hydrogen gas flows into the hydrogen bin 140 through the hydrogen outlet 133 of the replaceable hydrogen source storage cartridge 130 and is stored in the hydrogen bin 140. The hydrogen valve 150 may control the outflow state of hydrogen. When ignition mechanism 110 is operated to generate a spark, hydrogen valve 150 is opened and hydrogen flows out at a desired flow rate and is ignited by the spark generated by ignition mechanism 110 to generate a flame, thereby completing the ignition function of lighter 100.

In the specific embodiment shown in fig. 2, the hydrogen replaceable source storage box 130 comprises two partition layers 134, each partition layer 134 is -shaped partition layer 134, the -shaped partition layer 134 comprises a long side surface 136, a bottom surface 137 and a short side surface 138 which are connected in sequence, and the long side surface 136 is connected with the top of the box body 131.

And the solid hydrogen storage material 135 may be disposed at the bottom of the cartridge body 131 and at the bottom of the barrier 134. And the solid hydrogen storage material 135 is layered in different regions of the box 131, the solid hydrogen storage material 135 will be reacted layer by layer, and the reaction is more complete.

In some embodiments, the long side 136 and the short side 138 of the -shaped spacer 134 are flat, and the bottom 137 is a mesh, which allows the material entering the replaceable hydrogen source storage cartridge 130 from the water tank 120 to preferentially react with the solid hydrogen storage material 135 at the bottom of the cartridge body 131. As the reaction progresses, the material entering the replaceable hydrogen source storage cartridge 130 from the water tank 120 gradually accumulates upward and reacts with the solid hydrogen storage material 135 in the upper barrier layer 134, thereby achieving a layer-by-layer reaction of the solid hydrogen storage material 135.

In some embodiments, the case body 131 further includes a mounting groove provided at a side surface of the case body 131. The hydrogen outlet 133 may be provided on the mounting groove. The mounting groove can make the box body 131 more simple and convenient to mount and accurate in positioning.
