The piezoelectric ignited lighter with a safety device according to the present invention is to prevent the malfunction of the conventional piezoelectric ignited lighter with a simpler configuration to prevent the safety accident of the infant and the safety accident of the user.

2 is a perspective view showing a basic configuration of a piezoelectric igniter with a safety device according to the present invention.

As can be seen from Figure 2, the piezoelectric ignition type lighter with a safety device according to the present invention, the conventional piezoelectric ignition type that the piezoelectric element is activated by pressing the ignition button (2) provided on the upper case (1) The lighter includes a first metal plate 14, a rail groove 10, and a locking piece.

The guide groove 20 is formed by cutting upward from one side of the lower end side of the ignition button 2, that is, one side of the portion contacting the side of the case 1, and the guide groove 20 is cut height. It comprises a long groove 20a formed to be long and a short groove 20b formed so that its height is shorter than the long groove 20a. That is, the groove is formed of two grooves formed upwardly from one side of the lower end of the ignition button 2, but the two grooves are formed such that the lengths in the height direction (the longitudinal direction) are different from each other. It is called.

The guide groove 20 is arranged so that the engaging piece 30 moving along the rail groove 10 to be described later is inserted into the long groove 20a and the step groove 20b so that the ignition button ( It controls the downward movement of 2). The organic action of the guide groove 20 and the locking piece 30 will be described later together with the description of the rail groove 10 and the locking piece 30.

The rail groove 10 serves to limit the movement path while allowing the locking piece 30 to be movable so that the locking piece 30 flows from side to side. One side portion of the case 1, which is in contact with the groove 20, is recessed downward, that is, in a direction opposite to the guide groove 20, so that the case 1 and the ignition button together with the guide groove 20. A space of a certain size is provided between (2).

The length of the horizontal side (lateral side) of the rail groove 10 will be preferably formed to be the same as the length of the horizontal side of the guide groove 20 so that the locking piece 30 can flow in the inside. The height of the vertical side may be adjusted according to the shape and size of the locking piece 30 to be described later.

The catching piece 30 is formed to be able to flow left and right along a horizontal plane 10a of the rail groove 10 in a state inserted into a space between the guide groove 20 and the rail groove 10. It is to be arranged inside the long groove (20a) and the step groove (20b).

'와 유사한 형상으로 형성되어 그 내부에 상기 레일 홈(10)의 수평면(10a) 내지 상기 수평면(10a)의 하부가 끼워진 상태에서 좌우로 유동될 수 있도록 하는 것이 가장 바람직하다.The locking piece 30 may be configured in various shapes,

It is most preferably formed to have a shape similar to 'so that the horizontal surface (10a) to the lower portion of the horizontal surface (10a) of the rail groove 10 can be moved to the left and right in the state.

In addition, in such a locking piece 30, in order to allow the user to transmit pressure more easily, the lever 30a may be formed on one side of the lighter outer wall, and the lever 30a is the outer wall of the lighter. Protruding from the side to the outside in a specific shape to transmit a predetermined level of frictional force to the user's finger or the like so that the engaging piece 30 can be more easily flow. The lever 30a may be used in a variety of shapes without departing from its purpose, and a detailed description thereof will be omitted since it is a known technique.

At this time, the piezoelectric ignited lighter with a safety device according to the present invention is very small, and accordingly, the thickness of the case 1 and the thickness of the catching piece 30 are inevitably formed very thinly, as well as the lighter. In general, since the material is generally made of a material such as plastic, there is a problem that the bonding force between the receiving groove 13 and the catching piece 30 may be weakened, and its rigidity and durability may be weakened. In addition, the locking piece 30 is moved horizontally in a state in which it is in contact with the horizontal surface (10a) of the rail groove 10 to the lower portion of the horizontal surface (10a), the horizontal surface (10a) of the rail groove (10) The inner side wall of the case in contact with the catching piece 30 and the catching piece 30 (ie, the horizontal plane 10a in the case 1) so as not to be separated from the lower portion of the horizontal plane 10a. The first protrusion 11 and the first slit 31 are formed in the lower portion of the).

The first protrusion 11 protrudes from a portion of a portion of the inner wall of the case 1 which is in contact with the inner vertical surface of the locking piece 30 in a horizontal direction (direction parallel to the horizontal surface 10a). A first protrusion 11 extending to the second protrusion 11 is formed, and corresponds to the first protrusion 11 at an inner side wall (surface in contact with the inner side wall of the case 1) of the inner vertical surface of the locking piece 30. The first slit 31 is formed by forming a portion extending in the horizontal direction when the part is recessed, and the first slit 31 moves the first protrusion 11 in a state where a portion of the first protrusion 11 is inserted. In order to be moved in a sliding manner, the engaging piece 30 can be more stably coupled to one side of the case 1 so as not to be separated.

By adding the first protrusion 11 and the first slit 31, the case 1 and the catching piece 30, which have a very thin thickness, are more stably coupled to the first protrusion 11 and Due to the coupling of the first slit 31 can flow in a state that does not deviate from each other to increase the coupling force and durability to increase the life of the piezoelectric ignited lighter with a safety device according to the present invention.

Referring to one embodiment of the above-described configuration, when the user wants to use a piezoelectric ignited lighter with a safety device according to the present invention, by holding the locking piece 30, the first of the locking piece 30 The slit 31 is flowed by sliding along the first protrusion 11 to be disposed inside the long groove 20a, and then pressing the ignition button 2 downwardly causes the latching piece 30 to enter the long groove. The ignition button 2 can be completely pressed while being inserted into the inside of the 20a, thereby stimulating the piezoelectric element to generate an electric spark to use the spark generated by the lighter.

However, when the user stores the locking piece 30 in a state in which the locking piece 30 is disposed inside the step groove 20b after using the lighter, the height of the step groove 20b is increased even if the ignition button 2 is pressed. As the horizontal surface 10a comes into contact with the catching piece 30, the ignition button 2 is not fully pressed, that is, the pressure spring is applied to the piezoelectric element to stimulate the piezoelectric element to a greater pressure. It can't be pressed enough so that it doesn't ignite. Therefore, when the user does not arbitrarily move the locking piece 30 to the long groove 20a side, the ignition does not occur so that a safety accident does not occur due to mistakes or immature mischief of an infant during storage.

When configuring the piezoelectric ignited lighter having a safety device according to the present invention only by the above-described configuration, unlike the user's intention, the engaging piece 30 unintentionally by gravity or friction in the pocket, such as the long groove 20a There is a risk that the flow can be to the side, in order to solve the problem, the first projection 11 of the rail groove 10 is further formed with a projection (11a) to create an arbitrary flow of the locking piece (30) Alternatively, the receiving groove and the insertion portion may be further formed on one side of the case 1 and one side of the inner wall of the locking piece 30, respectively.

Figure 3 is a perspective view showing the configuration of the protrusion and the spring according to the present invention.

FIG. 3 is a perspective view of an inner side of the case 1 as viewed from the outside, and as shown in FIG. 3, the protrusion 11a may be further provided on the first protrusion 11, and the protrusion 11a may be provided. ) Is a portion protruding outward from the first protrusion 11 so that the portion close to the contact portion between the long groove 20a and the short groove 20b is thicker than the other portions of the first protrusion 11.

In other words, the protruding portion 11a provides a portion where the first slit 31 slides along the first protrusion 11 so that a greater pressure is required, so that the catching piece 30 is disposed on the protruding portion 11a. In the flow along the horizontal surface 10a of the rail groove 10 toward the long groove 20a side and the short groove 20b side, the locking means for allowing the locking piece 30 to flow only when artificially constant pressure is applied. It is to play a role. That is, the locking piece 30 in the state disposed on the end groove 20b side does not inadvertently flow to the long groove 20a side, thereby preventing the accident accident more reliably.

The protrusion degree of the protrusion 11a is such that the first slit 31 passes through the protrusion 11a without causing damage to the first slit 31 due to the protrusion 11a. It is desirable that the pressure to be applied to 30) be such that a certain level can be guaranteed.

Referring to FIG. 3 again, in the piezoelectric ignited lighter having a safety device according to the present invention, the locking piece 30 is moved to the inside of the long groove 20a in order to use the lighter, thereby preventing a safety accident. In order to eliminate the hassle to flow back to the inside of the step groove (20b) may further include a spring (40).

In order to include the spring 40, the fixing groove 11b must be formed on the surface of the first protrusion 11, and the fixing groove 11b is a surface of the first protrusion 11. It is recessed at the side and extends along the longitudinal direction of the first protrusion 11, that is, to have another groove for inserting the spring 40 on the surface of the first protrusion 11. .

The first end of the spring 40 is inserted into the receiving groove, one end of which is connected to the end portion of the end groove 20b in the fixing groove 11b, and the other end of the spring 40 is provided on the locking piece 30. It is connected to one side of the slit 31 so that when the user does not use the lighter, the locking piece 30 can be automatically flowed to the side groove 20b side due to the elastic action of the spring 40 will be.

In order to further include such a spring 40, a hole for allowing the spring 40 to be fixedly connected to one end of the locking piece 30 and the end of the receiving groove 20b side of the receiving groove should be provided. Of course.

When explaining the operation of the spring 40 in more detail, when the user wants to ignite using the lighter, by holding the locking piece 30 and pushing the spring 40 while pushing toward the long groove (20a) side by After the length of the spring 40 is increased, the locking piece 30 flows toward the long groove 20a, and in that state, the ignition button 2 is pressed downward to ignite.

Thereafter, when the catching piece 30 is released, the catching piece 30 automatically flows to the end groove 20b due to the elastic action of the spring 40, thereby preventing an accidental safety accident.

Figure 4 is a perspective view showing a detailed shape of the receiving groove and the insert according to the present invention.

Referring to Figure 4, in order to further supplement the problem, the portion in contact with the catching piece 30 on the outer surface of the case 1, the recessed in one side so as to be curvature extended in the longitudinal direction A plurality of grooves 13 are formed in a state spaced apart from each other by a predetermined interval, and the surface in contact with the outer surface of the case 1 in the locking piece 30 is partially accommodated in the receiving groove 13 but elastic Insertion portion 33 formed so that it may be to be formed further.

The receiving groove 13 is preferably such that the depth of the recess is thin and the recessed shape is formed to have a very smooth curve, the insertion portion 33 is made of a size smaller than the size of the receiving groove 13 It is formed to have a certain level of elasticity is inserted into the one receiving groove 13 by the pressure according to the pushing force of the user and then released, the process of being inserted into the other receiving groove 13 formed next to and separated It can be moved left and right repeatedly.

By having such a receiving groove 13 and the inserting portion 33, the locking piece 30 flows along the horizontal plane of the rail groove 10 to the predetermined level of the locking action by gravity or light external pressure The locking piece 30 is prevented from flowing so that an accidental safety accident can be prevented more reliably.

5 is a cross-sectional view showing the shape of the locking piece according to the present invention.

'와 유사한 형상으로 구비된 상기 걸림 편(30)의 두 수직 면 중 어느 하나는 그 길이가 다른 하나보다 길도록 형성되어 그 내구성 및 결합력을 증강시키도록 할 수 있고, 또한, 상기 걸림 편(30)과 상기 레일 홈(10)에는 각각 서로 끼워진 상태에서 슬라이딩 이동되도록 하는 제 1 슬릿(31) 및 제 1 돌기(11)와 유사한 제 2 슬릿(32) 및 제2 돌기(12)가 추가로 형성되도록 하여 그 결합력을 더욱 보강할 수 있다.

It is possible to further reinforce the bonding force.

The locking piece 30 is formed such that the sides in contact with the outside of the case 1 are longer than the sides in contact with the inside of the case 1 in two vertical surfaces so that the locking piece 30 opens the rail groove 10. When moving along, it is possible to increase the bonding strength and durability. In addition, the ends of the two vertical surfaces of the locking piece 30, that is, the lower portion, may be formed such that the thickness thereof becomes thinner toward the lower side in contact with the case 1, in which case the case 1 and The locking piece 30 has an effect that the adhesion is further increased.

In addition, on the outer surface of the case 1 in contact with the engaging piece 30, the case 1 has a second shape which protrudes from one side in a shape similar to the first protrusion 11 and extends in a horizontal direction. The protrusion 12 is further formed, and the surface contacting the outer surface of the case 1 in the locking piece 30 is recessed in a portion corresponding to the second protrusion 12 and extends in the horizontal direction to extend the first surface. A second slit 32 is formed to be moved in a sliding manner along the second protrusion 12 while a portion of the second protrusion 12 is inserted, thereby forming the first protrusion 11 and the first protrusion. Together with the slit 31, more stable coupling can be achieved.

By adding the second protrusion 12 and the second slit 32, the case 1 and the catching piece 30, which are made of a very thin thickness, are more stably coupled to the first and second protrusions and the first and second protrusions. The combination of 1,2 slits further reduces the possibility of being damaged by being separated from each other, thereby enhancing the durability of the lighter.

As another method for the purpose of augmenting the durability described above, first and second metal plates 14 and 34 may be further provided at a portion where the case 1 and the catching piece 30 contact each other.

Referring back to FIG. 5, the first metal plate 14 is a portion of the case 1 that contacts the locking piece 30, that is, the horizontal plane 10a to the horizontal plane 10a of the rail groove 10. The second metal plate 34 is attached to a portion of the catching piece 30 that contacts the case 1, that is, the inner wall of the catching piece 30.

At this time, the first and second metal plates 14 and 34 are covered to cover all of the first and second slits 31 and 32 and the first and second protrusions 11 and 12. 31 and 32 and the interaction between the first and second protrusions 11 and 12 may not be limited, and the first metal plate may be used to enhance durability of the first and second protrusions 11 and 12. The first and second protrusions 11 and 12 may be formed at 14.

In addition, it is possible to further apply a coating composition to the surface of the first and second metal plates 14, 34 to minimize the friction between each other to minimize the damage caused by the friction.

The first and second metal plates 14 and 34 not only solve the problem that the case 1 and the catching piece 30, which are generally made of plastic, rub against each other, so that durability thereof may be degraded, The additional rigidity of the first and second metal plates 14 and 34 of the metallic material may be increased to increase the rigidity of the case 1 and the catching piece 30.

In addition, the case 1 and the locking piece (the upper horizontal surface of the step groove 20b and the upper surface of the locking piece 30, which may be in contact with the locking piece 30 by pressing the ignition button 2). A shock absorbing material (not shown) may be further provided to prevent the 30 from being damaged and damaged by the pressure.

The cushioning material (not shown) is preferably made of a material such as elastic rubber to buffer the pressure repeatedly applied. By further providing such a cushioning material (not shown), by pressing the ignition button 2, the pressure applied to the horizontal surface of the step groove 20b to the upper surface of the catching piece 30 can be reduced so that the lighter can be used for a long time. If so, the damage caused can be greatly mitigated.
