Description

Technical Field

[0001] The utility model relates to the technical field of lighters, in particular to a lighter. Background Art

[0002] A lighter is a small fire-making device, mainly used for making fire, smoking, cooking and other fire-making. Traditional lighters are gas lighters, which require flammable gas as fuel and are easily extinguished when there is wind. In addition, there are safety hazards during use, storage and transportation. After years of development, more and more users choose arc lighters, which are safer and more convenient to use.

[0003] Existing arc lighters include an upper cover, a shell and an ignition device arranged in the shell. Generally, lighters are equipped with a safety switch to prevent accidental triggering. For some lighters with an upper cover, the movement of the upper cover is generally linked to the safety switch. When the upper cover is closed, the lighter will not be triggered externally. When the upper cover is opened, the lighter can be ignited by an external trigger.

[0004] However, if the upper cover is simply used as a safety switch, in real life, the upper cover may be opened by mistake due to looseness or the action of external force, which may cause the lighter to be accidentally triggered, resulting in danger. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] like Figure 1 and Figure 2 As shown, the utility model discloses a lighter, which includes a body 100 and a rotatable upper cover 200 of the body 100, one end of the upper cover is hinged to the body, so that the upper cover can rotate relatively to complete the action of opening and closing the cover. At the same time, similar to a conventional lighter, the action of the upper cover is linked to the primary trigger module to realize the switching of the opening signal and the closing signal, thereby ensuring that the secondary trigger module will not be triggered when the lighter is in the closed state, thereby avoiding the occurrence of accidental ignition during carrying.

[0027] The embodiment of the present application adopts a kerosene lighter, preferably an arc igniting cotton strip, which has been disclosed in the applicant's prior application documents, so the specific structure of the kerosene lighter will not be described in detail. In other embodiments, an arc lighter may also be used.

[0028] An ignition unit is provided in the fuselage 100, and the ignition unit includes an ignition element, a power supply and a control element. The ignition element is connected to the power supply 700 through the control element, wherein the ignition element includes two electrode wires of a high-voltage package and a cotton strip contacting with kerosene, and the electrode wires are relatively arranged at positions close to the cotton strip, and the cotton strip is ignited by driving an arc between the two electrode wires.

[0029] The control element comprises:

[0030] A first-level trigger module 400 is provided in linkage with the upper cover;

[0031] At least two secondary trigger modules connected in parallel;

[0032] The main control module is connected to the primary trigger module 400 and the secondary trigger module respectively, and when the primary trigger module is triggered, the secondary trigger module is in a triggerable state; and when two secondary trigger modules are triggered at the same time, the main control module drives the ignition element to work.

[0033] Among them, the first-level trigger module 400 has the highest priority, that is, the first-level trigger module needs to be triggered first before the main control module can obtain the signal of the second-level trigger module, and at least two second-level trigger modules are designed, and the trigger signal priorities of the two second-level trigger modules are consistent, that is, the two are triggered at the same time or successively within the set time to be the correct ignition signal, and the triggering of any one of the second-level trigger modules cannot make the main control module start ignition.

[0034] By providing at least two secondary trigger modules, it is possible to avoid the occurrence of accidental ignition when the primary trigger module is accidentally triggered.

[0035] As a preferred technical solution, at least one secondary trigger module includes a touch area 300 arranged on the surface of the body for contacting with the user's hand and an identification circuit 500 for identifying changes in touch signals in the touch area.

[0036] When the lighter needs to be held in hand during use, when the hand contacts the touch area, a secondary trigger module is triggered.

[0037] The identification circuit uses a touch chip U1 electrically connected to the electrode sheet of the touch area. The contact between the electrode sheet and the hand causes a change in the electrical level. Through this change, the touch chip U1 outputs a corresponding signal to the main control module, so that the main control module can identify the trigger signal of one of the secondary trigger modules.

[0038] Other secondary trigger modules are one or more of a voice control module, a vibration detection module or an airflow sensing module.

[0039] In this embodiment, another secondary trigger module is a voice control module, and the voice control module 600 includes:

[0040] Microphone MK1 for obtaining the start command, the microphone is used for sound-to-electric signal conversion;

[0041] A transmission circuit for transmitting the electrical signal converted by the microphone MK1.

[0042] The transfer circuit includes two transistors, the emitter of the transistor Q1 is grounded, the collector of the transistor Q1 is connected to the first receiving end of the main control module, the base of the transistor Q1 is connected to the collector of the transistor Q2, and the base of the transistor Q1 is also connected to the second receiving end of the main control module through a resistor R2, the emitter of the transistor Q2 is grounded, the base of the transistor Q2 is connected to a pin of the microphone through a capacitor C1, and the two ends of the capacitor C1 are respectively connected to the second receiving end of the main control module through resistors R3 and R4.

[0043] The sound signal is converted into an electrical signal through the transmission circuit, so that the main control module recognizes the trigger signal of another secondary trigger module. In this embodiment, it can be set to a sequential triggering method, that is, the handheld lighter is used as the first signal, and then the ignition is started by sound.

[0044] In other embodiments, a vibration detection module or an airflow sensing module can be used to trigger the start signal by shaking or exhaling, and the selection can be made according to demand, or multiple start methods can be set, with one trigger method as the main one and the other trigger methods as auxiliary ones. For example, touch is the main signal in the secondary trigger signal, and other methods are set in parallel, that is, shaking, voice control or exhalation can all achieve ignition.

[0045] The power supply includes a battery and a power management module. The power management module includes a charging management module, which is connected to the TYPE-C interface to realize charging management of the battery, ensuring that the battery can be charged when the battery power is low, so that it can be reused.

[0046] The power management module is also provided with a charging indication circuit, which includes a light-emitting diode D3, which detects the charging interface through a detection circuit composed of a resistor R10 and a resistor R13, and then inputs a charging signal to the main control module during charging, thereby controlling the light-emitting diode D3 to implement charging indication. Preferably, when the charging signal is input, the main control module can enter a dormant state to avoid being ignited by operation during charging.

[0047] The main control module is also provided with a working indication circuit to indicate when ignition is started.

[0048] The main control module includes a main control chip IC, which has a plurality of pins, one of which is connected to a driving circuit, through which the high-voltage package is energized, thereby generating an arc.

[0049] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
