Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The present disclosure provides a lighter 10, as shown in fig. 1, the lighter 10 includes an induction coil 101, a metal heating element 102, and a resonant circuit module 103.

The resonant circuit module 103 is connected to the induction coil 101, and is configured to output a high-frequency alternating current to the induction coil 101.

The metal heating member 102 is provided in cooperation with the induction coil 101, and is configured to generate self-heating under the action of electromagnetic induction generated after the induction coil 101 circulates a high-frequency alternating current, so that a user can conveniently use the heated metal heating member 102 to ignite.

For example, the high-frequency alternating current generally refers to an alternating current with a frequency greater than 50Hz (hertz), and in the embodiment of the present disclosure, refers to an alternating current with a frequency of 15 to 200kHz (kilohertz) or even higher. If the metal heating element 102 needs to be heated to a preset temperature in a short time, that is, the required heating efficiency is high, the resonant circuit module 103 may be set to output a high-frequency alternating current with a high frequency; if the metal heating member 102 is allowed to be heated to a preset temperature for a long time, i.e., the required heating efficiency does not need to be too high, the resonant circuit module 103 may be configured to output a low-frequency high-frequency alternating current.

In the technical scheme provided by the embodiment of the disclosure, electromagnetic induction is generated after the induction coil 101 circulates high-frequency alternating current, the metal heating element 102 generates eddy current under the action of the electromagnetic induction, and then self-heating is generated under the action of the eddy current, so that a user can ignite an object by using the heated metal heating element 102. Because the metal heating element 102 has higher stability, the vulnerability of the lighter 10 is reduced; meanwhile, as the lighter 10 does not generate dangerous objects such as electric arcs or open flames and the like, the use safety of users is greatly improved, and the user experience is better.

In one embodiment, as shown with reference to fig. 1, the induction coil 101 may be coiled as a hollow cylinder. The metal heating element 102 is disposed in a hollow region of a hollow cylinder.

Specifically, the induction coil 101 can generate electromagnetic induction after passing high-frequency alternating current, and the metal heating member 102 is located in a region where the intensity of the electromagnetic induction is the greatest, so that a large eddy current can be generated, and a self-heating effect can be generated with high efficiency.

In one embodiment, as shown in fig. 2, the induction coils 101 are wound in a spiral configuration on the same plane; the metal heating member 102 is disposed in a region having a distance from the induction coil 101 smaller than or equal to a preset distance.

Illustratively, the induction coil 101 is wound in a spiral structure on the same plane, i.e., the induction coil 101 may be wound in a mosquito coil shape. The metal heating member 102 is located on the upper side or the lower side of the induction coil 101, and is spaced apart from the induction coil 101 by a distance less than or equal to a predetermined distance. Since the intensity of electromagnetic induction generated after the induction coil 101 is supplied with the high-frequency alternating current is gradually reduced as the distance from the induction coil increases, the smaller the distance from the induction coil 101 is, the larger eddy current is generated in the metal heating member 102, and the higher the efficiency of self-heating is. The predetermined distance may be set in consideration of the strength of the electromagnetic induction generated by the induction coil 101 and the heating efficiency required to be satisfied by the metal heating member 102, which is not limited by the embodiment of the present disclosure.

In one embodiment, the lighter 10 further comprises insulation 104. The thermal shield 104 is disposed between the induction coil 101 and the metal heating member 102.

For example, the induction coil 101 may be an enameled copper coil, and in order to avoid the influence of a higher temperature caused by the self-heating of the metal heating element 102 on an enameled insulation layer of the induction coil 101, a heat insulation element 104 may be disposed between the induction coil 101 and the metal heating element 102, and the heat insulation element 104 may be made of a material such as ceramic or high temperature resistant glass.

If the induction coil 101 is coiled into a hollow cylinder, as shown in fig. 3, the thermal insulation member 104 can be a hollow cylinder with a diameter smaller than that of the induction coil 101 and is sleeved with the induction coil 101. The metal heating element 102 can be disposed in the hollow position of the heat insulating member 104 to achieve isolation from the induction coil 101.

If the induction coil 101 is coiled into a mosquito coil shape, as shown in fig. 4, the heat insulating member 104 may be a ceramic sheet or a glass sheet, and is located between the induction coil 101 and the metal heating member 102 to isolate the metal heating member 102 from the induction coil 101.

In one embodiment, lighter 10 further includes an upper rack 105 and a lower rack 106.

Wherein, the upper bracket 105 is matched with the metal heating element 102; the lower bracket 106 is disposed in cooperation with the induction coil 101. The upper bracket 105 is fixed to the lower bracket 106 for limiting the position and distance between the induction coil 101 and the metal heating member 102.

For example, if the induction coil 101 is wound as a hollow cylinder, as shown in fig. 5, the upper bracket 105 is provided with a first through hole 30a, and the metal heating member 102 includes a heating part 1021 and a limiting part 1022, and the diameter of the limiting part 1022 is larger than that of the first through hole 30 a. The induction coil 101 may be fixed to the lower bracket 106 through the resonant circuit module 103, the heat insulating member 104 is sleeved in the hollow region of the induction coil 101, and the heating part 1021 of the metal heating member 102 passes through the first through hole 30a and moves to the hollow region of the induction coil 101 until the restricting part 1022 is engaged with the first through hole 30 a. Specifically, the upper bracket 105 includes at least one notch provided with a through hole, the lower bracket 106 includes at least one protrusion provided with a through hole, the protrusion of the lower bracket 106 is clamped into the notch of the upper bracket 105, the through hole on the protrusion is aligned with the through hole on the notch, and a wedge is inserted into the aligned through hole to fix the clamping area of the protrusion and the notch, so as to fix the upper bracket 105 and the lower bracket 106. The fixed upper support 105 and lower support 106 can be as shown in fig. 6, so that the positions and distances among the induction coil 101, the metal heating element 102 and the heat insulation element 104 can be limited, and the heating effect or the heat insulation effect is prevented from being influenced by movement in the using process.

Alternatively, if the induction coil 101 is wound as a mosquito coil, as shown in fig. 7, the upper bracket 105 is provided with a second through hole 40a, and the metal heating element 102 includes a heating part 1021 and a restriction part 1022, and the diameter of the restriction part 1022 is larger than that of the second through hole 40 a. The induction coil 101 may be fixed to the lower bracket 106 by the resonant circuit module 103, and a heat insulator 105 is disposed on a side of the induction coil 101 adjacent to the upper bracket 105, the heat insulator 105 being a sheet-shaped disk. A metal heating element 102 is disposed above the heat insulation member 105, a heating portion 1021 of the metal heating element 102 passes through the second through hole 40a and moves in a direction away from the lower bracket 106 until the limiting portion 1022 is engaged with the edge of the second through hole 40a, and then the upper bracket 105 and the lower bracket 106 are fixed, so as to fix the induction coil 101, the metal heating element 102 and the heat insulation member 104, as shown in fig. 8, the position and distance among the three can be limited by the fixing, and the heating effect or the heat insulation effect is prevented from being influenced by the movement in the using process.

In general, in order to avoid the influence of the heat generated by the metal heating element 102 on the upper bracket 105, another heat insulating element 50a may be disposed between the metal heating element 102 and the upper bracket 105, as shown in fig. 7 and 8, the heat insulating element 50a is provided with a through hole, and the metal heating element 102 may pass through the through hole of the heat insulating element 50a and then pass through the second through hole 40a of the upper bracket 105.

It should be noted that the above-described structure may still achieve the function of igniting the lighter 10 by removing the thermal insulation member 104.

In one embodiment, a preset time rule describing a plurality of supply times and an interval time between two adjacent supply times may be stored in the resonance circuit module 103 in advance. The resonant circuit module 103 outputs a high frequency ac power to the induction coil 101 at a supply time according to a predetermined time rule.

For example, if the resonant circuit module 103 continuously outputs the high-frequency alternating current to the induction coil 101, the metal heating member 102 may continuously self-heat, and thus the temperature may be too high, and in order to avoid this, the resonant circuit module 103 may periodically output the high-frequency alternating current to the metal heating member 102.

Specifically, a preset time rule describing a supply time during which the high-frequency alternating current can be output to the metal heating member 102 and an interval time during which the output is stopped may be stored in the resonant circuit module 103 in advance. When the resonant circuit module 103 detects that the ignition switch is triggered, that is, the user needs to get fire, the high-frequency alternating current can be output to the metal heating element 102 in a periodic manner according to the supply time and the interval time described by the preset time rule, that is, the high-frequency alternating current is output to the metal heating element 102 at the supply time, and the output is stopped at the interval time. By so doing, the metal heating member 102 generates self-heating at the supply time, that is, a temperature rise occurs; self-heating is not generated at intervals, and the temperature is slowly cooled; then, the self-heating is continued to be generated at the next supply time, and the temperature is raised. The circulation can ensure that the temperature of the metal heating element 102 is maintained to be convenient for a user to get fire, and the condition that the lighter 10 is damaged due to overhigh temperature can be avoided, so that the service life of the lighter 10 is prolonged.

In one embodiment, as shown in fig. 9, lighter 10 further includes a power source 107. The power supply 107 is connected to the resonant circuit module 103 for supplying power to the resonant circuit module 103.

Illustratively, the lighter 10 further includes an ignition switch, which is connected to the power source 107 and the resonant circuit module 103, respectively. When the user needs to get a fire, the ignition switch can be triggered, i.e. pressed or clicked. When the ignition switch is triggered, the power supply 107 is connected to the resonant circuit module 103, that is, the power supply 107 supplies power to the resonant circuit module 103, and then the resonant circuit module 103 outputs high-frequency alternating current to the induction coil 101.

Embodiments of the present disclosure provide a lighter that includes an induction coil 101, a metal heating element 102, and a resonant circuit module 103. The induction coil 101 generates electromagnetic induction after passing through the high-frequency alternating current output by the resonant circuit module 103, and the metal heating member 102 generates eddy current under the action of the electromagnetic induction, so that self-heating is generated under the action of the eddy current, and a user can ignite an object by using the heated metal heating member 102. Because the metal heating element 102 has higher stability, the vulnerability of the lighter 10 is reduced; meanwhile, as the lighter 10 does not generate dangerous objects such as electric arcs or open flames and the like, the use safety of users is greatly improved, and the user experience is better.
