Description

A dry cell battery arc lighter Technical Field

[0001] This invention relates to the field of lighter technology, specifically to a dry cell battery arc lighter. Background Technology

[0002] Arc lighters generally require lithium batteries as their power source. However, in some regions or countries, there are strict restrictions on the express delivery of lithium batteries. This can lead to situations where lighters sold on online platforms cannot be delivered to buyers due to courier companies refusing to accept the packages, thus affecting online sales. Technical issues

[0003] To avoid packages being refused due to policy restrictions, some manufacturers have switched to using dry cell batteries as a power source. However, simply using dry cell batteries as a power source for lighters is problematic because arc lighters require higher voltage to operate. This necessitates boosting the voltage of the dry cell batteries, which can lead to unstable arcs and severely affect the lighter's performance. Technical solutions

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a dry battery arc lighter.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A dry cell battery arc lighter, comprising:

[0007] A power supply circuit for electrical connection with dry cell batteries;

[0008] The boost module is electrically connected to the power supply circuit and the power management module respectively, and is used to boost the output voltage of the dry cell battery.

[0009] The power management module has an energy storage capacitor connected in parallel at its output terminal. Based on the output voltage of the boost module, the energy storage capacitor electrically connected to it is charged and used as the working voltage.

[0010] The switch module is used to input control signals, including a first signal for start-up control and a second signal for arc generation control that are input sequentially.

[0011] The main control module outputs a stop signal to the boost module based on the first signal input from the switch module, and outputs an ignition signal to the arc drive module based on the second signal input from the switch module.

[0012] The arc drive module is electrically connected to the high-voltage transformer and drives the high-voltage transformer to generate an arc based on the ignition signal output by the main control module.

[0013] The boost module continues to supply power to the power management chip when it does not receive a stop signal from the main control module.

[0014] The boost module is based on the boost chip PW5150, and the boost chip PW5150 is electrically connected to the positive terminal of the power supply circuit through an energy storage inductor, and a capacitor C3 is connected in parallel across the two ends of the dry cell battery.

[0015] The switch module includes two switches, which are used to input a first signal and a second signal, respectively.

[0016] The arc drive module includes a MOSFET Q1. The drain (D) terminal of the MOSFET Q1 is electrically connected to one pin of the high-voltage transformer. The source (S) terminal of the MOSFET Q1 is grounded. The gate (G) terminal of the MOSFET Q1 is connected to the output terminal of the main control module. The other pin of the high-voltage transformer is connected to the positive terminal of the energy storage inductor.

[0017] The gate (G) terminal of the MOS transistor Q1 is connected to the output terminal of the main control module through resistor R4, and is also grounded through resistor R6.

[0018] It also has an indicator module.

[0019] The indicator module includes several light-emitting diodes that are respectively connected to different output terminals of the main control module. Beneficial effects

[0020] The beneficial effects of this invention are as follows: by using a boost module and a power management module to boost the output voltage of the dry cell battery and supply power to the energy storage capacitor, the energy storage capacitor can be used as the working voltage, which can effectively ensure the stability of the electric arc and improve the performance of the dry cell battery-based arc lighter.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

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

[0028] As shown in Figure 1, a dry cell battery arc lighter includes:

[0029] The power supply circuit consists of a positive electrode plate and a negative electrode plate, which are located at both ends of the battery compartment of the lighter. When a dry cell battery is placed in the battery compartment, it makes electrical contact with the dry cell battery to obtain the voltage of the dry cell battery. The dry cell battery 100 can be two 1.5V dry cell batteries, which can provide a voltage output of up to 3V. In some embodiments, a single dry cell 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 cell battery 100 and the power management module 300 respectively, and has an enable terminal EN for boosting the output voltage of the dry cell battery 100. It converts the 3V voltage output by the dry cell battery into the required voltage and supplies power to the power management module.

[0031] The power management module 300 has an energy storage capacitor 400 connected in parallel at its output terminal to provide the working voltage. Based on the output voltage of the boost module 200, the energy storage capacitor connected to it is charged and stored, and used as the working voltage. In other words, the energy storage capacitor is used as a power source, which can ensure a stable power output.

[0032] The switch module, as shown in Figure 2, is used to input control signals. It includes a first signal for starting and a second signal for controlling the generation of electric arc, which are input sequentially. The switch module can output different signals based on a single switch by varying the duration of pressing, or it can output different signals based on two switches.

[0033] As shown in Figure 3, the main control module outputs a stop signal to the enable terminal of the boost module based on the first signal input from the switch module, and outputs an ignition signal to the arc drive module based on the second signal input from the switch module.

[0034] The main control module is based on a microcontroller. It identifies the corresponding signals and outputs the corresponding signals through the input terminals connected to the switch module.

[0035] The arc drive module, as shown in Figure 4, is electrically connected to the high-voltage transformer. It drives the high-voltage transformer to generate an arc based on the ignition signal output by the main control module. The arc drive module is mainly used to ensure that the two pins of the high-voltage transformer are in a power-on circuit, thereby causing the high-voltage transformer to generate an arc.

[0036] When the boost module does not receive a stop signal from the main control module, it continuously supplies power to the power management chip, keeping the capacitor fully charged at all times. This allows for direct ignition operation when desired, without waiting.

[0037] Under normal conditions, the dry cell battery outputs a stable 5V voltage through the boost chip, and then charges the energy storage capacitor 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, stopping the boost and charging, thus isolating the dry cell battery and the energy storage capacitor. At this time, the action of the second switch can make the main control module output an ignition signal to the arc drive module, causing the high voltage transformer to generate an arc.

[0038] Meanwhile, the main control module can control the output of the stop signal by detecting the voltage value of the dry cell battery in real time. When the voltage value of the dry cell battery is lower than the set value, the boost chip stops working. After the dry cell battery is replaced, the boost chip resumes working. In actual operation, the stop signal is a change between high and low levels. That is, a high level output makes the boost chip work normally, while when the output is 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 level of this terminal can change between high and low.

[0040] The boost module is based on a boost chip 220, specifically a PW5150 model. The PW5150 boost chip is electrically connected to the positive terminal of the dry cell battery via an energy storage inductor 210, and a capacitor C3 is connected in parallel across the two ends of the dry cell battery. By using the energy storage inductor and capacitor C3, the boost chip can operate normally in continuous current mode.

[0041] In this embodiment, the switch module includes two switches, used to input a first signal and a second signal respectively. That is, they are controlled independently, each outputting different signals to achieve different functions. The switches must be operated sequentially to perform the ignition operation, which also ensures safety and reliability.

[0042] The arc driving module includes a MOSFET Q1. The drain (D) terminal of the MOSFET Q1 is electrically connected to one pin of the high-voltage transformer. The source (S) terminal of the MOSFET Q1 is grounded. The gate (G) terminal of the MOSFET Q1 is connected to the output terminal of the main control module. The other pin of the high-voltage transformer is connected to the positive terminal of the energy storage inductor. The main control module outputs a corresponding pulse signal, which causes the MOSFET to connect the high-voltage transformer to the power-on circuit, thereby causing the high-voltage transformer to generate an arc.

[0043] The gate (G) terminal of the MOSFET Q1 is connected to the output terminal of the main control module through resistor R4, and is also grounded through resistor R6, so that the ignition signal output by the main control module is more accurate.

[0044] The lighter also has an indicator module, which can be a single light indicator or a scrolling light indicator, etc.

[0045] As shown in Figure 5, the indicator module includes several light-emitting diodes (LEDs) that are connected to different output terminals of the main control module. The main control module outputs different pulse signals to make the LEDs light up sequentially to form a running light effect.

[0046] 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.
