Description

Technical Field

[0001] The utility model relates to a lighter, in particular to a double-flame lighter. Background Art

[0002] At present, lighters can be divided into single-flame lighters and double-flame or multi-flame lighters according to the number of flames. Among them, multi-flame lighters usually emit a windproof flame when the ignition button is pressed down, and turn to an open flame after releasing the button. The implementation method is usually to rely on the gas supply switching mechanism and two groups of flame components. The existing multi-flame lighters generally have multiple groups of flame components sharing one fire outlet. After the head cover is opened, the gas supply control mechanism is opened at the same time. When the button is pressed, the open flame gas supply hose is squeezed to block the gas supply, and the person ignites the windproof flame or the straight flame. After releasing the button, the open flame gas supply hose is unblocked to restore the gas supply, and the open flame is ignited under the residual heat of the windproof flame to complete the flame conversion. However, the existing lighters of this type are usually direct-access, and the fire outlet generally shares one, without oblique or side-hitting, and the form is relatively simple, and there are safety hazards. As for flame lighters with two different directions, there are generally two ways to switch the gas circuit: one is to achieve the switching of multiple gas circuits by installing a diverter control on the gas valve; the other is a multi-flame lighter as disclosed in Chinese patent CN201610236142.7, which has at least two groups of flame components, which are connected to the gas supply control mechanism through leather tubes respectively, and the gas circuit is switched by squeezing the corresponding leather tubes. Both of the above methods require the arrangement of two air pipes, i.e., air circuits, which lead to ignition ports in different directions in the shell. The internal layout is complicated, the components are too fragmented, and the internal structure cannot be modularized or compact, and the design is greatly restricted. Especially for pipe users, the most suitable one is the horizontal open flame, which cannot be integrated with other flame lighters and is not conducive to carrying. Summary of the invention

[0003] In order to solve the above technical problems, the utility model adopts the following technical solutions: a fire outlet structure of a gas lighter, which is connected to the gas outlet pipeline of the gas outlet assembly in the shell, and the fire outlet structure is respectively provided with an upper fire outlet and a side fire outlet on the upper top surface and the side surface of the shell, and comprises an inner tube connected to the end of the gas outlet pipeline, an outer tube sleeved outside the inner tube with a spacing, and a top cover covering the top of the inner tube, and an upper gas outlet is provided on the top section of the inner tube or the top cover, and the outer tube can slide along the length relative to the inner tube, and the outer tube and the inner tube can slide relative to each other. There are an upper gas outlet position and a side gas outlet position between the tubes. At the upper gas outlet position, an upper gas outlet channel is formed by the gas outlet pipe, the inner pipe and the upper gas outlet. The gas can be ignited after mixing with the air through the upper gas outlet channel to the upper fire outlet. At the side gas outlet position, the top cover closes the upper top surface of the outer tube, and the upper gas outlet channel is closed at the same time. A side gas outlet channel is formed by the gas outlet pipe, the inner pipe, the notch opened on the top section of the inner pipe, the spacing space between the inner pipe and the outer pipe, and the side gas outlet. The gas can be ignited after mixing with the air through the side gas outlet channel to the side fire outlet.

[0004] As an improvement: the top cover is connected to the upper top of the inner tube, the notch and the upper air outlet are both opened on the circumferential wall of the upper part of the inner tube; in the upper air outlet position, the upper part of the inner tube extends out relative to the upper top part of the outer tube, and the notch and the upper air outlet are both exposed outside the upper top of the outer tube; in the side air outlet position, the upper part of the inner tube shrinks inward relative to the outer tube, the notch and the upper air outlet are moved into the outer tube, and the upper air outlet opening is closed relative to the upper fire outlet, that is, the upper air outlet channel is in a closed state at the upper fire outlet, and the gas passes through the air outlet pipe, the inner tube, the notch and / or the upper air outlet, the spacing space between the inner tube and the outer tube, the side air outlet to the side fire outlet in sequence and is mixed with the air before being ignited.

[0005] As an improvement: the notch is shared by the upper peripheral wall of the inner tube and the upper air outlet.

[0006] As an improvement: a stage ring is also provided on the inner tube at the upper air outlet position or at a position below the upper air outlet. The peripheral wall of the stage ring has a large number of micro-air holes penetrating the ring body. At the upper air outlet position, the stage ring forms a slow-release air storage belt on the inner tube.

[0007] As an improvement: the top cover is connected to the upper top of the inner tube, and the upper air outlet is opened on the lower bottom surface of the top cover. In the upper air outlet position, the inner tube carries the top cover away from the upper top of the outer tube, and the upper air outlet is exposed at the upper fire outlet, opening the upper air outlet channel. The gas passes through the air outlet pipe, the inner tube and the upper air outlet to the upper fire outlet and is mixed with the air before being ignited; in the side air outlet position, the top cover is pressed and sealed on the upper top surface of the outer tube, and the upper air outlet channel is closed by pressing the outer tube wall or the upper top sealing surface of the outer tube against the lower bottom surface of the top cover. The gas passes through the air outlet pipe, the inner tube, the notch in the outer tube, the spacing space between the inner tube and the outer tube, the side air outlet to the side fire outlet and is mixed with the air before being ignited.

[0011] The beneficial effects provided by the utility model are: a single air outlet pipe is used to supply air to the fire outlet in both horizontal and vertical directions, and two air paths in different directions are formed by the inner and outer pipes, and the air path switching is realized by the position change caused by the relative movement between the inner and outer pipes. Since the inner and outer pipes are in a telescopic relationship, for the whole machine, it can still be a "single" pipe layout, the internal layout is very concise, and the assembly is convenient, which provides a basis for modularization and is conducive to the compactness of the whole machine. Furthermore, the fire outlet structure of the utility model does not limit the flame type of the fire outlet, that is, the two air outlets can be compatible with various types of flame generators such as flame pagodas, and it has strong versatility and certain expansibility.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0018] like Figure 1 , Figure 2As shown, the first embodiment of the fire outlet structure of the utility model gas lighter, the fire outlet structure is connected to the gas outlet pipeline of the gas outlet assembly in the shell, the fire outlet structure is respectively provided with an upper fire outlet A and a side fire outlet B on the upper top surface and the side surface of the shell, and comprises an inner tube 1 connected to the end of the gas outlet pipeline, an outer tube 2 sleeved outside the inner tube with a spacing, and a top cover 3 covering the top of the inner tube, and an upper gas outlet 5 is provided on the top section of the inner tube, and the outer tube 2 is slidable along the length relative to the inner tube, and there is a gap between the outer tube 2 and the inner tube 1 as the outer tube 2 slides relative to the inner tube 1. The upper gas outlet position and the side gas outlet position, at the upper gas outlet position, the upper gas outlet channel formed by the gas outlet pipe, the inner pipe 1 and the upper gas outlet 5, the gas can be ignited after mixing with the air through the upper gas outlet channel to the upper fire outlet; at the side gas outlet position, the top cover 3 closes the upper top surface of the outer pipe, and the upper gas outlet channel is closed at the same time, and the side gas outlet channel is formed by the gas outlet pipe, the inner pipe, the notch 6 opened on the top section of the inner pipe, the spacing space between the inner pipe and the outer pipe, and the side gas outlet 4, and the gas can be ignited after mixing with the air through the side gas outlet channel to the side fire outlet. In this embodiment, the inner pipe is a telescopic pipe and the outer pipe is a fixed pipe to achieve relative movement of the inner and outer pipes, that is, in the length direction, the outer pipe is fixed in the shell, and at the side gas outlet position, the side gas outlet 4 is opened on the outer pipe corresponding to the side fire outlet position. Of course, the inner pipe is also used as a fixed pipe, and the relative sliding is achieved by the movement of the outer pipe. When the outer pipe is movable, it is necessary to limit the side gas outlet on the outer pipe to reach and face the side fire outlet when the side gas outlet position is used. The top cover 3 of this embodiment is integrally formed and connected to the top of the inner tube. The top cover 3 can cover the opening of the top surface of the outer tube after the outer tube rises. The shape of the top cover 3 can be adapted to the opening of the top surface of the outer tube. The notch 6 and the upper air outlet 5 are both provided on the upper peripheral wall of the inner tube 1. The position of the upper air outlet 5 on the inner tube is higher than the notch 6, so that the upper air outlet 5 can be closed by the upper top wall of the inner tube at the side air outlet position. Of course, the upper air outlet 5 can also be used as a through-port for the inner tube to the spacing space between the inner tube and the outer tube at the side air outlet position, that is, it has the same function as the notch 6. In this embodiment, the inner tube extends out of the outer tube to the upper air outlet position, and the upper part of the inner tube extends relative to the upper top part of the outer tube. The notch 6 and the upper air outlet 5 are both exposed outside the upper top of the outer tube. The gas can be ignited after mixing with the air through the outlet pipe, the inner tube 1, the upper air outlet 5 and the notch 6 to the upper fire outlet. At the side gas outlet position, the upper part of the inner tube shrinks inward relative to the outer tube, the notch 6 and the upper gas outlet 5 move into the outer tube, and the upper gas outlet opening is closed relative to the upper fire outlet, that is, the upper gas outlet channel is closed at the upper fire outlet, and the gas is sequentially passed through the gas outlet pipe, the inner tube, the notch 6 and the upper gas outlet 5, the spacing space between the inner tube and the outer tube, the side gas outlet 4 to the side fire outlet and mixed with the air before being ignited. The upper gas outlet 5 and the notch 6 of this embodiment have the same function as the position moves on the inner tube, the only difference being that the notch 6 is directed toward the side gas outlet. Of course, the upper gas outlet 5 can be set with multiple holes, and the notch 6 is shared with the upper gas outlet 5 on the upper peripheral wall of the inner tube 1.

[0019] like Figure 3The second embodiment shown is different from the first embodiment in that the upper air outlet 5 is provided on the lower bottom surface of the top cover 3, and the notch 6 is provided on the wall of the inner tube. In this embodiment, the inner tube is a telescopic tube and the outer tube is a fixed tube to achieve relative movement of the inner and outer tubes, that is, in the length direction, the outer tube is fixed in the shell, and at the side air outlet position, a side air outlet 4 is provided on the outer tube corresponding to the side fire outlet position. As the inner tube extends out of the outer tube to the upper air outlet position, the inner tube takes the top cover 3 away from the upper top of the outer tube, the lower bottom surface of the top cover 3 where the upper air outlet 5 is located is separated from the upper top of the outer tube, the upper air outlet 5 is exposed and opened, and the upper air outlet channel is in an open state. The gas passes through the air outlet pipe 9, the inner tube 1 and the upper air outlet 5 to the upper fire outlet and is mixed with air and can be ignited into a flame. At the upper air outlet position, the notch 6 on the wall of the inner tube can extend out of the outer tube to assist the upper air outlet to discharge gas, and the notch 6 can also be closed by the thickness of the upper top wall of the outer tube. When the flame is turned to the side, the inner tube is retracted into the outer tube to the side air outlet position through operation, and the top cover 3 is pressed and sealed on the upper top surface of the outer tube. The upper air outlet is closed by crimping the outer tube wall or the upper top sealing surface of the outer tube to the lower bottom surface of the top cover 3, thereby realizing the closure of the upper air outlet channel. The gas is sequentially transferred through the air outlet pipe, the inner tube, to the gap 6 in the outer tube, the spacing space between the inner tube and the outer tube, the side air outlet 4 to the side fire outlet, and then mixed with the air and ignited into a flame.

[0020] like Figure 4 The third embodiment shown is different from the first embodiment in that the outer tube is used as a movable tube, and the inner tube is a fixed tube in the outer shell, and the fire structure is provided with a notch 6 and an upper air outlet 5 in a common ring on the upper peripheral wall of the inner tube 1. The lower bottom of the movable outer tube in this embodiment is an open bottom, and the height is controlled by setting a sealing ring 8 between the middle section or the lower section of the inner tube, that is, between the inner and outer tubes, so as to form a closed spacer ring in the space between the inner and outer tubes without restricting the movement of the outer tube, that is, at the side air outlet position, a closed spacer ring is formed in the space between the inner tube and the outer tube through the sealing ring 8, which is lower than the side air outlet 4. The inner tube of this embodiment is also provided with a platform ring 7 at the position of the upper air outlet 5 or at a position adjacent to the lower position of the upper air outlet 5. The peripheral wall of the platform ring 7 has a large number of micropores 71 penetrating the ring body, at the upper air outlet position. Because the aperture of the micropore 71 is much smaller than the upper air outlet, the platform ring forms a slow-release gas storage belt on the inner tube. The slow-release gas storage belt and the upper fire outlet are located at the root of the flame, which has a certain slow-release diffusion of the fuel gas, stretches the root of the flame, protects the fire core, and makes the flame have a certain wind resistance. The outer tube is pushed up to the side air outlet position and turned to the side fire outlet. The platform ring is sealed in the side air outlet channel and cooperates with the upper air outlet, i.e., the gap 6, to enlarge and thicken the root of the flame at the side fire outlet, especially for the horizontal open flame of the pipe user, it is safer and more stable to use.

[0021] Of course, the flames of the two fire outlets can be open flames or other flames. It can be connected with flame pagodas as needed, and the compatibility and expandability are very good. In addition, the inner and outer pipes of the utility model can form a module, which is convenient for assembly and maintenance. In terms of space, the inner and outer pipes can save more space than the existing double gas channel arrangement, which is conducive to the miniaturization of the whole machine, the streamlined internal layout, and the internal layout of the whole machine is clearer and simpler.

[0022] Although the utility model has been disclosed as above in terms of specific embodiments, it is not intended to limit the utility model. Any technician in this field can make slight changes and modifications without departing from the spirit and scope of the utility model. Therefore, the scope of protection of the utility model should be determined by the scope of the attached claims.
