Description

Technical Field

[0001] The utility model specifically relates to an electric heating fuel integrated lighter. Background Art

[0002] A kerosene lighter is a small, portable fire-making device, which is mainly used to make fire and ignite combustible materials, such as cigarettes, firewood, grass, paper and other ignitable materials. The principle of making fire with a kerosene lighter is to rub the flint and the friction wheel. Sparks will be generated during the friction process, and the sparks will splash onto the cotton thread with kerosene to cause ignition. However, there are four major disadvantages in existing kerosene lighters: first, the flint is easily consumed and needs to be replaced frequently. There is no function for storing flint, which is inconvenient to replace the flint; second, when a fire is needed, it is necessary to touch the friction wheel with a finger to rotate the friction wheel and rub the flint to ignite a fire; third, the safety is relatively low. Traditional kerosene lighters often leak kerosene and cause accidental friction and fire between the friction wheel and the flint.

[0003] In order to solve the problem that the current kerosene lighters need the cooperation of friction wheels and flints to achieve ignition, kerosene lighters with other ignition methods are also launched on the market. For example, Chinese patent CN220269432U discloses a kerosene lighter based on arc ignition, which uses electrodes arranged near the cotton core and uses high voltage to generate an arc to ignite the cotton core, thereby achieving ignition control. However, the arc ignition method requires a built-in high-voltage package, which is relatively large in size. In a lighter of the same volume, the high-voltage package will squeeze the space of the fuel tank, thereby reducing the capacity of kerosene. At the same time, the arc ignition method requires a large amount of electricity, thereby increasing the consumption of the battery. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an electrically heated fuel integrated lighter.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] An electric heating oil integrated lighter comprises a body 1 and a cover body 2 connected to the body 1, one end of the cover body 2 is hinged to the body, and the cover body is rotatably or detachably connected to the body. The rotatable connection allows the cover body to rotate relative to the body to achieve a closed and open state switch. Ignition can be performed when the cover body is open, and ignition cannot be performed when the cover body is closed.

[0027] The body is composed of an outer shell, an oil storage chamber 6 and an upper mounting frame 7. The cotton core seat 9 and the heating wire 10 are arranged on the upper mounting frame. The control circuit board is arranged in the space between the outer shell and the oil storage chamber. The upper mounting frame is fixedly connected with the oil storage chamber to form a whole, and the whole is inserted into the outer shell to fix the internal control circuit board.

[0028] The cotton core seat 9 is arranged at one end of the machine body and can be covered by the rotated cover body. At least one cotton core is installed on the cotton core seat. The whole cotton core seat can be detachably connected to the upper mounting frame, so that the cotton core can be replaced when it is burned out.

[0029] The electric heating wire 10 is arranged on any side of the cotton core seat and can ignite the cotton core on the cotton core seat when powered on. When powered on, the electric heating wire will heat up and then ignite the cotton core;

[0030] The control circuit board is arranged in the body and outside the oil storage cavity, and is used to control the heating of the electric heating wire. The control circuit board refers to the relevant structure for controlling the operation of the electric heating wire, such as the main control circuit board 3, the battery 4 and the switch 5, wherein the battery is used as a power supply and is connected to the main control circuit board and one end of the electric heating wire respectively. The main control circuit board can control whether the electric heating wire forms a path under the triggering of the switch, and then generates heat in the power-on state. The control principle is common knowledge, so it is not described in this application.

[0031] The oil storage cavity 6 is arranged inside the fuselage. Since kerosene is stored, a number of installation spaces are provided on the outside of the oil storage cavity, which are respectively used to place the main control circuit board and the battery. After being inserted into the outer shell, the two realize the fixation of the control circuit board and the battery. A first space 12 for placing the main control circuit board is provided on one side of the oil storage cavity, and a second space 13 for placing the battery is provided on the other side. The battery and the main control circuit board are arranged on both sides of the oil storage cavity, and the oil storage cavity is used to achieve isolation between the two, so as to avoid the influence of battery heating on the main control circuit board. At the same time, it can also ensure that the weight of the two sides is consistent, so that the hand feel is better.

[0032] The heating wire 10 may also be arranged on one side of the cotton core seat, and may be one heating wire directly arranged on one side of the cotton core seat.

[0033] Preferably, the heating wire is arranged around the cotton core seat, and the heating wire can be distributed on the outside of the cotton core seat in a rectangular shape, or distributed on the outside of the cotton core seat in a circular shape.

[0034] The circumferential arrangement allows the cotton core to be heated more evenly and can be ignited quickly.

[0035] The electric heating wire comprises two spiral ends, which are arranged in parallel on both sides of the cotton core seat, one end of the two spiral ends is connected, and the other end serves as an electrical connection end electrically connected to the control circuit board.

[0036] One end of the body is recessed to form a mounting groove 71, and the cotton core seat and the heating wire are both arranged in the mounting groove. The mounting groove is directly recessed to prevent the object to be burned from directly contacting the heating wire or the cotton core seat during use, thereby preventing the heating wire from being damaged.

[0037] A porcelain cup seat 72 is provided between the heating wire and the bottom of the installation groove, and the porcelain cup seat is used to prevent the heating wire from contacting with conductive parts (such as metal shells or metal insulation parts) to thereby prevent the heating wire from being damaged.

[0038] The porcelain cup seat extends upward in the circumferential direction to form an annular wall, and the highest surface of the heating wire is arranged below the annular wall, thereby placing the heating wire completely in the porcelain cup seat, avoiding contact between the heating wire and other places, and reducing the possibility of damage to the heating wire.

[0039] A plurality of vent holes 11 are provided on both sides of the mounting groove to provide oxygen during combustion.

[0040] An upper mounting frame fixedly connected to the oil storage cavity is arranged in the fuselage, and the cotton core seat and the electric heating wire are both fixedly arranged on the upper mounting frame.

[0041] A third space 14 is provided at the upper end of the oil storage cavity near the hinge point of the cover body for placing a switch. The switch is two metal sheets arranged opposite to each other. When the cover body is opened, a driving member linked to the cover body rotates to press one of the metal sheets and makes it contact with the other metal sheet, thereby making the circuit conductive.

[0042] An upper oil chamber 8 is formed between the oil outlet of the oil storage chamber and the upper mounting frame, that is, the upper mounting frame extends downwardly from the outside of the cotton core seat to form a first side wall, and the oil outlet of the oil storage chamber extends upward in the circumferential direction to form a corresponding second side wall. The first side wall and the second side wall are staggered and fitted, and preferably a seal is provided at the connection between the two to ensure the sealing performance of the upper oil chamber. At the same time, the cotton core of the cotton core seat extends downward and is placed in the upper oil chamber, and the bottom of the upper oil chamber is formed by another cotton core and extends to the bottom of the oil storage chamber. The design of the segmented cotton core and double oil chambers can reduce the volatilization rate of kerosene and extend its use time.

[0043] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
