Description

Technical Field

[0001] This utility model relates to the field of ignition tool technology, specifically to a kerosene lighter. Background Technology

[0002] A kerosene lighter is a type of lighter that uses kerosene as fuel. It generally includes a fuel tank, a wick, and an ignition assembly. The fuel tank supplies fuel to the wick, and the ignition assembly ignites the wick. Conventional ignition assemblies are a flint and a grinding wheel. For example, Chinese patent CN216897383U discloses a kerosene lighter with a visible fuel level, which uses a flint and a grinding wheel to generate a spark that ignites the wick. Chinese patent CN220269432U discloses a kerosene lighter based on electric arc ignition, replacing the original flint and grinding wheel with an electric arc ignition method, directly using an electric arc to ignite the wick. As a novel kerosene lighter design, it has been well-received by consumers. However, using an electric arc for ignition requires a separate power supply, while kerosene lighters require the addition of kerosene, thus requiring users to... Paying attention to both battery level and kerosene level is crucial. Insufficient battery level will prevent the lighter from functioning properly, and this dual focus can be exhausting for the user. To address this issue, some manufacturers have offered solutions, such as the Chinese patent CN205402793U, which discloses a combination structure of a rechargeable lighter and a flint lighter. This method allows for different ignition methods, but the two ignition methods operate independently. Essentially, it integrates an arc lighter and a flint lighter, with each operating independently. It does not utilize the ignition of a wick to achieve an open flame, thus altering the nature of kerosene lighters and impacting sales. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a kerosene lighter.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A kerosene lighter, comprising:

[0006] The housing has a cavity, and an ignition area is provided at its upper end;

[0007] The fuel tank is detachably installed in the cavity, with an ignition end at one end. The ignition end passes through the housing and is located at the ignition area. The ignition end is equipped with a cotton wick. An installation chamber is formed between the upper side of the fuel tank and the fuel tank.

[0008] The grinding wheel ignition assembly is detachably located on one side of the ignition area, and part of it is placed in the installation chamber;

[0009] An arc ignition assembly includes a control component disposed within a cavity and an arc head disposed on a housing, the arc head being disposed toward the cotton wick and located on the other side of the ignition area.

[0010] The housing is composed of a frame, a middle shell and a bottom cover assembly. The middle shell has openings at both the top and bottom ends, with its upper end fixedly connected to the frame and its lower end equipped with an openable bottom cover assembly.

[0011] The frame is provided with mounting holes, and the grinding wheel ignition assembly can be inserted and removed into the mounting holes.

[0012] The oil tank is detachably installed inside the housing, and the oil tank includes a tank body and a cotton core fixing seat installed at the upper end of the tank body.

[0013] The cotton core fixing seat extends outward in the circumferential direction to form a baffle.

[0014] The bottom cover assembly includes a base and a cover plate hinged to the base, and a locking assembly is provided between the cover plate and the base.

[0015] The locking assembly includes a buckle plate disposed between the cover plate and the base. The upper surface of the buckle plate extends upward to form a buckle that engages with the base. The buckle plate has a first position that engages with the base and a second position that moves in the opposite direction to the buckle position under the action of an external force and releases the buckle from the base.

[0016] An observation window is provided on the side of the casing corresponding to the oil tank.

[0017] A head cover is also hinged to the upper end of the shell.

[0018] The head cover is equipped with a sealing cap adapted to the ignition area.

[0019] The beneficial effects of this utility model are as follows: By setting the grinding wheel ignition component and the electric arc ignition component on both sides of the cotton wick, the cotton wick can be ignited by grinding wheel ignition or electric arc ignition respectively. When the electric arc ignition component is low on power, the cotton wick can be ignited by grinding wheel ignition, without having to constantly monitor the power level. At the same time, by utilizing the deformation of the oil tank, installation space for the grinding wheel ignition component is reserved in the housing, which can add the grinding wheel ignition function without changing the size of the lighter.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] like Figure 1 As shown, a kerosene lighter includes a housing 100, an oil tank 400 disposed within the housing 100, and a grinding wheel ignition assembly 300 and an arc ignition assembly 500 disposed on both sides of the oil tank 400. The oil tank is an independent structure, while the arc ignition assembly and the grinding wheel ignition assembly are modularly designed. The arc ignition assembly and the oil tank are arranged side-by-side within the housing. A recess at the upper end of the oil tank forms a mounting chamber with the housing to accommodate the grinding wheel ignition assembly, thus adding a grinding wheel ignition function to a lighter with a fixed width.

[0032] Meanwhile, the arc generation position of the arc ignition component is set to correspond to the wick. That is, the wick can be ignited by the arc or by the friction of the grinding wheel ignition component. Both can be used to ignite the wick. When the power is sufficient, the wick can be ignited directly by the arc. When the power is insufficient and the wick has been forgotten to be recharged, the wick can be ignited by the grinding wheel ignition component. This avoids the lighter failing due to a single ignition method.

[0033] The ignition switch design of the arc ignition component in this application can refer to the applicant's earlier Chinese patent CN222417539U, which can control the arc through a dual triggering method. In this embodiment, the opening of the head cover can also be used as the primary trigger signal. The secondary trigger signal can be two parallel technical solutions as described in CN222417539U, or a single secondary trigger signal can be used, such as voice control, exhalation, shaking, fingerprint verification, etc. This point is not a major technical improvement point of this application, so it will not be described in detail.

[0034] See Figure 3 The housing 100 has a cavity and an ignition area 700 at its upper end. The housing 100 is composed of a frame 110, a middle shell 120 and a bottom cover assembly 130. The middle shell 120 is open at both the upper and lower ends and is fixedly connected to the frame 110 at its upper end. The bottom cover assembly 130 is openable at its lower end.

[0035] The middle shell 120 has a hollow structure with two openings at the top and bottom, which facilitates the installation of components such as the arc ignition assembly. The frame is fixed to the upper end of the middle shell and cooperates with the base of the bottom cover assembly to fix and limit its position, thus realizing an integrated shell design. The frame is partially embedded in the middle shell and fixedly connected to the inner wall of the middle shell. At the same time, the base is also partially embedded in the middle shell and fixedly connected to the inner wall of the middle shell. This connection method can be a snap-fit, a screw fixation, or a direct interference fit to achieve the connection of the three components.

[0036] Meanwhile, the bottom cover assembly is also equipped with a cover that can be opened relative to the base, so that the internal oil tank can be replaced by opening the cover. This application adopts a replaceable oil tank design, which can change the oil by replacing the entire oil tank. Compared with the previous refueling method, this method is simple and convenient and will not cause kerosene leakage during replacement.

[0037] See Figure 7The oil tank 400 is detachably disposed within the cavity, with an ignition end at one end. In this embodiment, the ignition end can be considered as the upper end face of the wick holder. The ignition end passes through the housing and is located at the ignition area 700, and a wick 600 is provided at the ignition end. An installation chamber 150 is formed between the upper side of the oil tank and the oil tank 400. The installation chamber is formed by the recess at the upper end of the oil tank 400, and the size of the recess is preferably adapted to the length of the flint of the grinding wheel ignition assembly. The volume of the oil tank is reduced to accommodate the flint of the grinding wheel ignition assembly.

[0038] The oil tank 400 includes a tank body 420 and a wick holder 410 disposed on the upper end of the tank body 420. The upper end of the tank body has a through hole connecting to the interior, through which the wick holder is inserted. Several sealing rings are provided between the wick holder and the inner wall of the through hole to achieve a seal and ensure reliable connection. Furthermore, the wick holder has a through hole through which the wick enters to the bottom of the oil tank, facilitating the guidance of kerosene to the combustion end.

[0039] The cotton wick holder 410 extends outward in the circumferential direction to form a baffle 411. The ignition area is provided with a through hole that matches the diameter of the cotton wick holder. That is, after the oil tank is inserted into place, part of the cotton wick holder protrudes through the through hole. At the same time, the cotton wick corresponds exactly to the grinding wheel ignition assembly and the arc head. The diameter of the baffle of the cotton wick holder is larger than the diameter of the through hole. At the same time, a sealing ring is provided between the baffle and the housing. The sealing inside the housing is achieved by using this sealing.

[0040] Meanwhile, the separate design of the cotton core holder 410 and the housing 420 makes it easy to replace the cotton core or reuse it. Kerosene can be added by disassembling the cotton core holder.

[0041] See Figure 4 and Figure 8 The grinding wheel ignition assembly 300 is detachably disposed on one side of the ignition area 700 and partially placed in the installation chamber 150. The grinding wheel ignition assembly includes a bracket and a grinding wheel 310 rotatably disposed on the bracket 320. The bracket is provided with a flint mounting hole, and the flint is installed in the flint mounting hole with its upper end in contact with the grinding wheel. The rotation of the grinding wheel rubs against the flint to generate a spark that ignites the cotton wick.

[0042] The entire grinding wheel ignition assembly 300 is modularly designed. The frame 110 is provided with mounting holes 111, and the grinding wheel ignition assembly 300 can be inserted and removed into the mounting holes 111. That is, the bracket can be inserted into the mounting hole, and several sealing rings are provided between the bracket and the mounting hole arm to seal and fix it.

[0043] The arc ignition assembly 500 includes a control assembly disposed within a cavity and an arc head 510 disposed on a housing. The arc head 510 is disposed toward the cotton wick 600 and is located on the other side of the ignition area 700.

[0044] like Figure 5 As shown, the electric arc head and the grinding wheel ignition assembly are arranged opposite each other, located on both sides of the ignition area 700, while the two do not interfere with each other and can ignite the cotton wick respectively.

[0045] The arc head is fixedly mounted on the frame and can be fixed to the frame by bolts or screws. The frame is provided with a windproof wall 112 surrounding the ignition area. The windproof wall has an opening on the side facing the grinding wheel ignition assembly. The arc head is located inside the windproof wall, and the electrodes of the arc head are set towards the cotton wick, so that the arc generated between the two electrodes can directly ignite the cotton wick. At the same time, the windproof wall located between the grinding wheel ignition assembly and the arc head is provided with several strip holes.

[0046] like Figure 9 As shown, the control assembly includes a control circuit board and an intermediate housing 520 for fixing the control circuit board. The intermediate housing is used to support and fix the control circuit board 530, power supply and high voltage transformer and other components. The intermediate housing is directly fixed to the frame, so that the control assembly and the frame are integrated into one unit, which facilitates subsequent installation.

[0047] The bottom cover assembly 130 includes a base 132 and a cover plate 131 hinged to the base 132. A locking assembly is provided between the cover plate 131 and the base 132. The base 132 is fixedly connected to the middle shell, and the cover plate 131 can be opened relative to the base. It can be opened by rotation or by sliding. In this embodiment, the rotation opening method is preferred, that is, one end of the cover plate is hinged to the base, and the other end is locked by the locking assembly.

[0048] The locking component can adopt a snap-fit ​​structure.

[0049] like Figure 6 As shown, the locking assembly includes a buckle plate 134 disposed between the cover plate 131 and the base 132. The upper surface of the buckle plate 134 extends upward to form a buckle 135 that engages with the base 132. The buckle plate 134 has a first position that engages with the base 132 and a second position that moves in the opposite direction to the buckling position under the action of external force and releases the buckling state from the base 132.

[0050] In this embodiment, a corresponding groove is provided on the cover plate. The buckle plate can be slidably disposed in the groove and is fixed between the connecting parts by the pressure plate 136. At the same time, the buckle extends upward. The distance from one end of the pressure plate to the buckle is greater than the amount of movement of the buckle to release the buckle from the latching state. Thus, when the buckle plate moves in the groove, the buckle can release the buckle from the latching state of the base. At the same time, an elastic element (not shown in the figure) is provided on the rear side of the buckle plate, so that the buckle plate has a tendency to move towards the first position.

[0051] The cover plate is hinged to the base. After the latching state is released, it can rotate relative to the base, exposing the space for replacing the oil tank. At this time, the oil tank can be removed from the housing by vibration or downward force for replacement. In order for the cover plate to be opened relative to each other, the end of the cover plate protrudes slightly upward and contacts an elastic drive block. When the cover is closed, the protrusion presses the drive block 133, putting it in an energy storage state. When the latching state on one side is released, it will give the cover plate a downward force.

[0052] like Figure 2 As shown, the housing 100 is provided with an observation window 140 on the side corresponding to the fuel tank 400. Preferably, the fuel tank is designed with a transparent material, so that the fuel level in the fuel tank can be directly observed from the observation window, which is convenient for timely replacement of the fuel tank.

[0053] like Figure 2 As shown, a head cover 200 is also hinged to the upper end of the housing 100. A sealing cover 210 adapted to the ignition area 700 is provided at the head cover 200. After the head cover is closed, the sealing cover seals the entire ignition area or seals the cotton wick to ensure that kerosene will not leak from the cotton wick during the carrying process.

[0054] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
