Description

Technical Field

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

[0002] Arc lighters generally require lithium batteries as their power supply. However, in some regions or countries, there are relatively strict restrictions on the express delivery of lithium batteries. As a result, when lighters are sold on the Internet platform, the courier will refuse to accept them, resulting in the inability to deliver the lighters to the buyers, affecting online sales.

[0003] In order to avoid the situation where express delivery is rejected due to policy, existing manufacturers use dry batteries as power sources. If dry batteries are used as the power source of lighters, the arc lighter needs a higher voltage to work, so the dry batteries need to be boosted. Direct voltage boosting will cause arc instability, seriously affecting the use effect. Utility Model Content

[0026] 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.

[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] like Figure 1 As shown, a dry cell electric arc lighter, comprising:

[0029] The power supply circuit is a positive electrode sheet and a negative electrode sheet, which are arranged at both ends of the battery compartment of the lighter, and are used to electrically contact the dry battery when the dry battery is placed in the battery compartment to obtain the voltage of the dry battery. The dry battery 100 can be two 1.5V dry batteries, which can provide a voltage output of up to 3V. In some embodiments, a single dry battery can also be used to achieve a 1.5V voltage supply so that it can work normally;

[0030] The boost module 200 is electrically connected to the dry battery 100 and the power management module 300, and has an enable terminal EN for boosting the output voltage of the dry battery 100, converting the 3V voltage output by the dry battery into the required voltage and supplying power to the power management module;

[0031] The power management module 300 has an energy storage capacitor 400 connected in parallel at its output end for providing a working voltage. According to the output voltage output by the boost module 200, the energy storage capacitor electrically connected thereto is charged and stored, and used as a working voltage, that is, the energy storage capacitor is used as a power source, which can ensure a stable power output;

[0032] Switch modules, such as Figure 2 As shown, it is used to input a control signal, which includes a first signal for starting and a second signal for arc generation control input in sequence; the switch module can be based on one switch, outputting different signals by different pressing time, or based on two switches, respectively outputting different signals;

[0033] Main control module, such as Figure 3 As shown, a stop signal is output to the enable end of the boost module according to a first signal input by the switch module, and an ignition signal is output to the arc driving module according to a second signal input by the switch module;

[0034] The main control module is based on a single chip microcomputer, which outputs corresponding signals respectively by identifying corresponding signals through input terminals connected to the switch modules respectively.

[0035] Arc drive module, such as Figure 4 As shown, it is electrically connected to the high-voltage package and drives the high-voltage package to generate an arc according to the ignition signal output by the main control module. The arc driving module is mainly used to put the two pins of the high-voltage package in a power-on circuit, thereby causing the high-voltage package to generate an arc.

[0036] When the boost module does not receive the stop signal output by the main control module, it continues to provide power to the power management chip, always maintaining the capacitor in a fully charged state, and can directly operate the ignition when it is desired without waiting.

[0037] Under normal conditions, the dry battery outputs a stable 5V voltage through the boost chip, and the energy storage capacitor is charged through the power management chip of the power management module. When the first switch is pressed during use, the main control module outputs a stop signal, which makes the level of the enable terminal EN of the boost chip low, stops boosting and charging, and puts the dry battery and the energy storage capacitor in an isolated state. At this time, the action of the second switch can enable the main control module to output an ignition signal to the arc drive module, so that the high-voltage package generates an arc.

[0038] At the same time, the main control module can control the output of the stop signal by detecting the voltage value of the dry battery in real time. When the voltage value of the dry battery is lower than the set value, the boost chip stops working. After replacing the dry battery, the boost chip resumes working. In actual work, the stop signal is a change of high and low levels, that is, a high level output makes the boost chip work normally, and when the output is a low level, the boost chip stops working.

[0039] When the enable terminal EN is directly connected to the main control module, it needs to be grounded through a pull-down resistor R1 to ensure that the voltage level at this terminal can vary.

[0040] The boost module is based on a boost chip 220, the model of which is PW5150, and the boost chip PW5150 is electrically connected to the positive electrode of the dry cell through an energy storage inductor 210, and a capacitor C3 is connected in parallel at both ends of the dry cell. By providing the energy storage inductor and the capacitor C3, it is ensured that the boost chip can work normally in the continuous current mode.

[0041] In this embodiment, the switch module includes two switches, which are used to input the first signal and the second signal respectively, that is, they are controlled separately, and output different signals respectively to achieve different functions. The switches need to be operated in sequence to perform the ignition operation, which also plays a role of safety and reliability.

[0042] The arc driving module includes a MOS tube Q1, a D end of the MOS tube Q1 is electrically connected to a pin of a high-voltage package, an S end of the MOS tube Q1 is grounded, a G end of the MOS tube Q1 is connected to an output end of a main control module, another pin of the high-voltage package is connected to a positive electrode of an energy storage inductor, and a corresponding pulse signal is output through the main control module, so that the MOS tube connects the high-voltage package to a power-on circuit, thereby causing the high-voltage package to generate an arc.

[0043] The G end of the MOS tube Q1 is connected to the output end of the main control module through the resistor R4, and is also grounded through the resistor R6, so that the ignition signal output by the main control module is more accurate.

[0044] The lighter is also provided with an indication module, which can be a single light indication or a revolving light indication.

[0045] like Figure 5 As shown, the indication module includes a plurality of light emitting diodes respectively connected to different output ends of the main control module. The main control module outputs different pulse signals to make the light emitting diodes light up in sequence to form a marquee effect.

[0046] 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.
