Description
Technical Field
[0001] The utility model relates to the technical field of fire lighters, in particular to a fire lighter with a protruding flame head. Background Art
[0002] A lighter refers to a device that can provide enough heat energy to ignite flammable items in an instant and maintain a stable flame. It is mainly installed on a flamethrower and has the functions of heating, baking and igniting some items.
[0003] A traditional lighter mainly involves a shell, an air storage box arranged in the shell, an electronic igniter, an ignition button, a jump piece, and an ignition mechanism. The air storage box involves an air outlet needle, and the ignition fuse of the electronic igniter is led to the vicinity of the ignition mechanism. When this type of lighter is used, the ignition button drives the electronic igniter to perform an ignition action, and at the same time drives the jump piece, so that the jump piece drives the air outlet needle to work, so that the gas in the air storage box overflows. When the gas reaches the air outlet position of the ignition mechanism, the electronic igniter ignites the gas overflowing from the air storage box, thereby realizing ignition of the lighter.
[0004] After the lighters currently available on the market are assembled, their outer shells are mostly fixed structures, that is, after the electronic igniter drives the ignition mechanism to ignite, the ignition can only be emitted in one direction, and the ignition angle cannot be controlled; and correspondingly, there are also a small number of lighters currently available on the market, whose outer shells are decomposed into several parts, namely the ignition head part of the lighter, which is separately led to the outside through an extension mechanism, and the extension mechanism can carry the ignition head part for rotation, thereby realizing that the ignition angle of the lighter can be controlled, and its rotation angle is generally converted between 30°, 60° or 90°.
[0005] However, in actual use, it was found that this type of lighter with controllable ignition angle had an unreliable assembly design due to the connecting head that rotates on the lighter, which also serves as the rotating axis. As a result, the user experience is not good when the lighter is rotated, and it is impossible to judge whether the ignition head of the lighter has been rotated into place. Summary of the invention
[0006] In view of the above-mentioned shortcomings, the utility model provides a lighter with a fire head that can rotate reliably and can conveniently determine whether it has been rotated to the right position.
[0007] To achieve the above purpose, the utility model adopts an igniter with a long ignition head, including a shell, an ignition button, an electronic igniter, a gas storage mechanism, an air bleed pipe, a jumper, a ignition mechanism, and a rotating shaft. The shell includes an ignition drive shell and an ignition execution shell. The ignition drive shell and the ignition execution shell are rotatably connected through the rotating shaft. The gas storage mechanism and the electronic igniter are both limited in the ignition drive shell. The electronic igniter has a preset ignition line. The ignition button is distributed on one side of the electronic igniter. The driving action of the electronic igniter is executed by the ignition button, and the gas discharge action of the gas storage mechanism is executed by the jumper. The ignition mechanism is distributed in the ignition execution shell.
[0008] The ignition mechanism includes an air intake part and a ignition outlet part, the air intake part faces the ignition drive housing, and is connected to the air outlet position on the air storage mechanism through an air duct, the rotating shaft includes a placement cavity, an elastic member and a rolling body, the elastic member and the rolling body are sequentially arranged in the placement cavity, and the rolling body is supported by the elastic member and extends out of the placement cavity, and forms an arc-shaped convexity at the top of the placement cavity, and a plurality of continuously arranged convex grooves that are adapted to the arc-shaped convexity are formed on the ignition execution housing relative to the position for executing rotational connection with the ignition drive housing, and through the cooperation of the plurality of continuously arranged convex grooves and the arc-shaped convexity, the ignition execution housing rotates around the rotating shaft and executes corresponding angle limiting.
[0009] The above-mentioned beneficial effect lies in: by connecting the rotating shaft for connecting the ignition drive shell and the ignition execution shell of the lighter, the components involved include a placement cavity, an elastic member and a rolling body, that is, the elastic member and the rolling body are designed by sequentially placing them in the placement cavity, that is, after the rolling body is placed in the placement cavity, it is supported by the elastic member. Compared with the existing rotating shaft, a through cavity is set on the shaft body of the rotating shaft, and the through cavity is large at one end and small at the other end. The specific installation is: the rolling body is first placed from the large end, and the small end is limited and clamped, and then the spring is placed immediately, and the large end is sealed by a fastener. The assembly of the rotating shaft involved in the utility model can be realized more conveniently, and after assembly, the contact between several continuously arranged convex grooves The surface is larger, and at the same time, since the rolling body is directly placed in the placement cavity and supported by the elastic member, that is, since the rolling body is loose, when the ignition execution shell rotates around the rotating shaft, the rolling body will also roll, and at the same time, since the rolling body is located between two adjacent convex grooves, the elastic member will be compressed to a certain extent, thereby making it possible for the rolling body to re-pop out and hit the convex groove when one convex groove is converted to another convex groove, that is, to achieve a clicking sound when the ignition execution shell is rotated, which informs the operator that the ignition lighter has its ignition mechanism rotated into place at a certain angle, thereby ensuring the reliability of the design of the lighter. At the same time, the lighter involved in the utility model can also be used as a decompression device for some specific people at certain times because of the clicking sound when it rotates.
[0010] The utility model is further configured as follows: a connecting cavity for inserting the rotating area of the ignition execution shell is opened on the ignition drive shell towards the side of the ignition execution shell, a placement limit cavity is opened on the side wall of the connecting cavity, and an insertion swing cavity is opened on the rotating area of the ignition execution shell. The rotating shaft also includes a limiting portion distributed on the outer edge for adapting to the insertion limit cavity, and a plurality of continuously arranged convex grooves are distributed on the cavity wall of the insertion swing cavity. In the stage of matching between the rotating shaft and the ignition drive shell and the ignition execution shell, the limiting portion cooperates with the inserted limit cavity to form the upper limit position of the rotating shaft on the ignition drive shell, and the matching of the plurality of continuously arranged convex grooves with the arc-shaped outer protrusion to form the ignition execution shell to perform a rotation action around the rotating shaft.
[0011] Through the above-mentioned arrangement, the rotating shaft can be reliably matched with the ignition drive housing and the ignition execution housing, and after the matching, the rotating shaft can be reliably limited without affecting the reliable rotation of the ignition execution housing, thereby ensuring the reliability involved in the utility model, and also ensuring that the ignition execution housing can be reliably rotated on the lighter through the position of the rotating shaft, and can rotate back and forth freely without being easily damaged.
[0012] The utility model is further configured that the elastic member supports and extends out of the rolling body of the placement cavity, and the extending height thereof exceeds half of the rolling body; the elastic member is a spring, and the rolling body is a ball.
[0013] Through the above arrangement, the clicking sound can be reliably emitted, and the distribution height of the rolling body in the rotating shaft is guaranteed. At the same time, it also avoids the situation that the ignition execution shell cannot be reliably positioned when rotating due to insufficient distribution height of the rolling body, that is, it cannot be supported at a certain angle.

[0023] like Figure 1-9As shown, the specific embodiment of the utility model is an igniter with a long ignition head, including a shell, an ignition button 12, an electronic igniter, a gas storage mechanism, an air bleed pipe, a jumper, a ignition mechanism 4, and a rotating shaft 2. The shell includes an ignition drive shell 1 and an ignition execution shell 3. The ignition drive shell 1 and the ignition execution shell 3 are rotatably connected through the rotating shaft 2. The gas storage mechanism and the electronic igniter are both limited in the ignition drive shell 1. The ignition line is preset on the electronic igniter. The ignition button 12 is distributed on one side of the electronic igniter. The driving action of the electronic igniter is executed by the ignition button 12, and the gas discharge action of the gas storage mechanism is executed by the jumper. The ignition mechanism 4 is distributed in the ignition execution shell 3;
[0024] The ignition mechanism 4 includes an air intake portion 41 and an ignition outlet portion. The air intake portion 41 faces the ignition drive housing 1 and is connected to the air outlet position on the air storage mechanism through an air duct. The rotating shaft 2 includes a placement cavity 23, an elastic member 22 and a rolling body 21. The elastic member 22 and the rolling body 21 are sequentially arranged in the placement cavity 23, and the rolling body 21 is supported by the elastic member 22 and extends out of the placement cavity 23, and forms an arc-shaped convexity 211 at the cavity top of the placement cavity 23. A plurality of continuously arranged convex grooves 311 that are adapted to the arc-shaped convexity 211 are formed on the ignition execution housing 3 relative to the position for executing rotational connection with the ignition drive housing 1. Through the cooperation of the plurality of continuously arranged convex grooves 311 and the arc-shaped convexity 211, the ignition execution housing 3 rotates around the rotating shaft 2 and executes corresponding angle limiting.
[0025] The above-mentioned rotating shaft 2 for connecting the ignition drive shell 1 of the lighter and the ignition execution shell 3 includes a placement cavity 23, an elastic member 22 and a rolling body 21, that is, the elastic member 22 and the rolling body 21 are designed by sequentially placing them in the placement cavity 23, that is, after the rolling body 21 is placed in the placement cavity 23, it is supported by the elastic member 22.

At the same time, since the rolling body 21 is between two adjacent convex grooves 311, the elastic member 22 will be compressed to a certain extent. As a result, when one convex groove 311 is converted to another convex groove 311, the rolling body 21 will pop out again and hit the convex groove 311, that is, when the ignition execution shell 3 is rotated, a clicking sound will be found, which informs the operator that the ignition mechanism 4 of the lighter has been rotated into place at a certain angle, thereby ensuring the reliability of the design of the lighter. At the same time, the lighter involved in the utility model will produce a clicking sound when it rotates. For some specific people, it can also be used as a decompression device at certain times.

The rotating shaft 2 also includes a limiting portion 22 distributed on the outer edge for adapting to the placement limit cavity 11, and a plurality of continuously arranged convex grooves 311 are distributed on the cavity wall of the placement swing cavity 31.
