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] The utility model provides a fire-emitting structure of a gas lighter with a simple internal structure.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a fire outlet structure of a lighter, which is connected to the air outlet pipe of the air outlet component in the shell, 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 air outlet pipe, an outer tube with a spacing sleeved outside the inner tube and with an upper cover, the inner tube is provided with an air vent connected to the air outlet pipe on the top, the upper cover of the outer tube comprises a closing surface that can close the air vent of the inner tube, and an upper air outlet opened in an area away from the closing surface, the outer tube is provided with a side air outlet corresponding to the side fire outlet on the tube wall below the upper cover, the inner tube is also provided with a notch that is relatively higher than the side air outlet and away from the area where the air vent is located, and the The outer tube and the inner tube can move up and down relatively to each other, and an upper air outlet position and a side air outlet position are provided between the outer tube and the inner tube with the relative up and down movement. At the upper air outlet position, the upper cover of the outer tube is away from the upper top of the inner tube in height, that is, the closed surface of the upper cover of the outer tube is separated from the air vent on the upper top of the inner tube, and an upper air outlet channel leading to the upper fire outlet is formed by the air outlet pipe, the inner tube, the air vent and the upper air outlet, and the gas can be ignited after mixing with the air through the upper air outlet channel to the upper fire outlet; at the side air outlet position, the upper cover of the outer tube presses the upper top of the inner tube, and the closed surface of the upper cover of the outer tube closes the air vent on the upper top of the inner tube, the upper air outlet channel is closed, and a side air outlet channel is formed by the air outlet pipe, the inner tube, the notch, the spacing space between the inner tube and the outer tube, and the side air outlet, and the gas can be ignited after mixing with the air through the side air outlet channel to the side fire outlet.

[0005] As an improvement: the notch is located at the junction of the top of the inner tube and the tube wall, that is, the notch forms a "7"-shaped notch on the top edge of the inner tube.

[0006] As an improvement: the inner tube is a hollow tube without a top, the upper tube opening of the inner tube is a vent, and the notch is located on the tube wall of the inner tube.

[0007] As an improvement: the outer tube of the fire outlet structure is a movable tube, and the inner tube is a fixed tube in the outer shell. At the side air outlet position, the side air outlet on the outer tube is exposed corresponding to the side fire outlet position.

[0008] As an improvement: the inner tube of the fire outlet structure is a movable tube, and the outer tube is fixed in the outer shell in the length direction. At the side air outlet position, a side air outlet is opened on the outer tube corresponding to the side fire outlet position.

[0009] As an improvement, the outer tube sleeved outside the inner tube can rotate around the inner tube, and the exposure of the side air outlet to the side fire outlet is controlled by the rotation of the outer tube.

[0010] 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 tubes, and the air path switching is realized by the position change caused by the relative movement between the inner and outer tubes. Since the inner and outer tubes are in a telescopic relationship, for the whole machine, it can still be a "single" tube 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. The inner and outer tubes only use relative sliding and grooving to realize the generation and switching of the two air paths. The structure is simple, reasonable, and easy to implement, and it is very convenient to process and assemble.

In the description of the present utility model, it should be understood that the terms "connected", "connected", "fixed" and the like used in the present utility model should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, or integrated; it can be a mechanical connection or a welding connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. 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.

[0016] like Figure 1 , Figure 2 , Figure 3As shown, the utility model is an embodiment of a fire outlet structure of a lighter, which is a gas lighter, which is connected to the air outlet pipe of the air outlet component in the shell, and 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 air outlet pipe, an outer tube 2 with a spacing sleeved outside the inner tube and with an upper cover 3, and the inner tube is provided with an air vent 11 connected to the air outlet pipe on the top. The inner tube of this embodiment is a hollow tube with an upper top surface, and the air vent 11 is provided on the upper top surface, and the size and number of the air vent 11 are determined according to the needs. Of course, the inner tube of a hollow tube without a top can also be directly used, and the upper tube opening of the inner tube is the air vent 11, and the notch 6 is located on the tube wall of the inner tube. The upper cover 3 of the outer tube includes a closing surface 31 that can close the inner tube vent 11, and an upper air outlet 32 ​​opened in an area away from the closing surface. The outer tube is provided with a side air outlet 21 corresponding to the side fire outlet on the tube wall below the upper cover. The inner tube is also provided with a notch 6 that is relatively higher than the side air outlet and away from the vent area. The notch 6 of this embodiment is located at the junction of the upper top of the inner tube and the tube wall, that is, the notch forms a "7"-shaped notch on the top edge of the inner tube.

[0017] The outer tube and the inner tube can move up and down relative to each other, and there is an upper gas outlet position and a side gas outlet position between the outer tube 2 and the inner tube 1 with the relative up and down movement. The fire outlet structure of this embodiment adopts a movable outer tube type, that is, the outer tube is a movable tube, and the inner tube is a fixed tube in the shell. At the side gas outlet position, the side gas outlet 21 on the outer tube is exposed corresponding to the side fire outlet position. Since the height of the side gas outlet on the outer tube is lower than the notch 6, the gas is output upward due to the density relationship and leads to the outside through the gas outlet. There is basically no gas output from the side gas outlet. Of course, in order to ensure that there is no gas output from the side gas outlet at the upper gas outlet position, the side gas outlet can also be covered and closed by the inner wall of the shell at the upper gas outlet position. The outer tube sleeved outside the inner tube can also be arranged to be rotatable with the inner tube as the center. The exposure of the side gas outlet to the side fire outlet is controlled by the rotation of the outer tube, which can not only ensure smooth gas outlet, but also prevent foreign matter from entering and preventing pollution without the need for a side cover. Of course, the inner tube movable type can also be adopted, that is, the inner tube of the fire outlet structure is a movable tube, and the outer tube is fixed in the shell in the length direction, and a side gas outlet 21 is provided on the outer tube at the side gas outlet position corresponding to the side fire outlet position. Compared with the inner tube movable type, the outer tube movable type can effectively avoid the problem of bending and clogging caused by deformation of the gas outlet pipe directly connected to the inner tube, and has higher stability.

[0018] like Figure 2 As shown, at the upper gas outlet position, the upper cover of the outer tube is away from the upper top of the inner tube in height, that is, the closed surface of the upper cover of the outer tube is separated from the vent hole 11 on the upper top of the inner tube, and an upper gas outlet channel leading to the upper fire outlet is formed by the gas outlet pipe, the inner tube 1, the vent hole 11 and the upper gas outlet 32. The gas can be ignited after mixing with the air through the upper gas outlet channel to the upper fire outlet.

[0019] like Figure 3 As shown, at the side gas outlet position, the upper cover of the outer tube presses the top of the inner tube, the closed surface of the upper cover of the outer tube closes the vent hole 11 on the top of the inner tube, the upper gas outlet channel is closed, and the side gas outlet channel is formed by the gas outlet pipe, the inner tube, the notch 6, the spacing space between the inner tube and the outer tube, and the side gas outlet 21. The gas can be ignited after mixing with the air through the side gas outlet channel to the side fire outlet.

[0020] The ignition of the upper fire outlet and the side fire outlet can be independent or generated by the pilot fire, which can be set according to actual needs. Of course, the flames of the two fire outlets can be open flames or other flames, and the flame pagoda can be added as needed, with very good compatibility and expandability. 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 dual gas channel arrangement, which is conducive to the miniaturization of the whole machine, streamlined internal layout, and makes the internal layout of the whole machine clearer and simpler.

[0021] 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.
