Description

Technical Field

[0001] This utility model relates to the field of ignition device technology, specifically a magnetically rechargeable tinderbox. Background Technology

[0002] A tinderbox, as a portable ignition device, is widely used in outdoor activities, camping, emergency lighting, and other scenarios. Its core function is to produce a flame by igniting combustibles to meet the user's ignition needs.

[0003] Traditional tinderboxes have many shortcomings in use, especially in terms of opening and closing mechanism, ease of operation, safety, and durability. They are difficult to meet the needs of modern users for efficiency, safety, and convenience. Traditional tinderboxes usually use a threaded connection to open and close, which requires the user to rotate it multiple times to fully open or close. The operation is cumbersome and time-consuming. In emergency situations, such as when rapid ignition is required, this design obviously cannot meet the user's needs. Utility Model Content

[0004] The purpose of this invention is to provide a magnetically rechargeable tinderbox to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a magnetically rechargeable tinderbox, including a shell, an inner mounting housing, a charging head mounted on the bottom of the mounting housing, a battery and a circuit board mounted inside the mounting housing, an airflow sensor, a control chip and an indicator light mounted sequentially from bottom to top on the circuit board, a combustion chamber mounted on the top of the circuit board, a heating wire mounted inside the combustion chamber, a first magnet ring mounted on the outer side of the top of the mounting housing, a cover snapped onto the outer side of the top of the mounting housing, and a second magnet ring mounted inside the cover.

[0006] Preferably, the charging head is electrically connected to the battery.

[0007] Furthermore, the charging head is an interface for connecting to an external power source, which can transfer external electrical energy to the battery to charge it. The charging head and the battery are connected by wires or circuits to ensure that electrical energy can be effectively transferred.

[0008] Preferably, the circuit board is electrically connected to the output terminal of the battery.

[0009] Furthermore, the circuit board is the core component controlling the entire tinderbox circuit. The battery supplies power to the circuit board through its output terminal. After receiving the power from the battery, the circuit board can provide the necessary power to the airflow sensor, control chip, indicator light, and heating wire.

[0010] Preferably, the airflow sensor, control chip, indicator light, and heating wire are all electrically connected to the circuit board.

[0011] Furthermore, the airflow sensor, control chip, indicator light, and heating wire are all functional components on the circuit board. They are connected to the circuit board through circuits. The airflow sensor is used to detect changes in airflow, the control chip is used to process sensor signals and control the operation of other components, the indicator light is used to display the working status, and the heating wire is used to generate high temperature to ignite the fire source.

[0012] Preferably, the top of the first magnet ring is magnetically connected to the bottom of the second magnet ring.

[0013] Furthermore, the first magnet ring is installed on the top outer side of the mounting housing, and the second magnet ring is installed inside the housing cover. When the housing cover is closed, the first and second magnet rings attract each other through magnetic force, ensuring that the housing cover is firmly fixed to the mounting housing and preventing the housing cover from accidentally falling off.

[0014] Preferably, one end of the indicator light passes through the mounting housing and the outer casing and extends to the outside of the outer casing.

[0015] Furthermore, one end of the indicator light passes through the mounting housing and the outer casing, extending to the outside of the casing, so that the user can directly observe the status of the indicator light from the outside, such as charging status, working status, or fault status.

[0016] Preferably, a connecting ring is fixedly connected to the top of the shell cover, and multiple hollow ventilation holes are provided at the bottom of the combustion chamber.

[0017] Furthermore, a connecting ring is fixedly connected to the top of the cover. The connecting ring can be used to suspend or carry the tinder. The bottom of the combustion chamber is designed with multiple hollowed-out ventilation holes. These ventilation holes can ensure that there is enough air circulation inside the combustion chamber to support the normal combustion of the heating wire. They also make it convenient for the user to blow air into the combustion chamber. The airflow enters the mounting housing through the multiple hollowed-out ventilation holes at the bottom of the combustion chamber and is then monitored by the airflow sensor to start the tinder.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] When using this invention, the user simply pulls open the cover. The cover is magnetically connected by a first and second magnetic ring, making opening quick and easy. After opening, the user blows air into the combustion chamber. The airflow passes through multiple perforated ventilation holes at the bottom of the combustion chamber and enters the mounting housing. An airflow sensor detects the change in airflow and transmits a signal to the control chip. The control chip then triggers the heating element on the circuit board to heat up. Located within the combustion chamber, the heating element ignites the combustible material, producing a flame. After the heating element has been running for a period of time, the control chip automatically shuts it off. When charging is needed, the mounting housing is connected to an external power source via a charging head at the bottom. The internal battery is charged, and the charging head is electrically connected to the battery to ensure effective energy storage during charging. An indicator light is electrically connected to the circuit board to display the working status of the tinder. For example, the indicator light may be red during charging and green when fully charged. When igniting, the indicator light may flash or display other colors to inform the user of the current status. One end of the indicator light runs through the mounting housing and the outer shell, allowing the user to see the status of the indicator light directly. After use, the user only needs to bring the cover close to the outer shell, and the first and second magnetic rings will automatically magnetically close, ensuring a tight seal and preventing flame leakage or dust ingress. Opening and closing via magnetic attraction makes operation more convenient and saves time, making it particularly suitable for quick use in emergency situations. Attached Figure Description

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.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A magnetic rechargeable tinderbox includes a housing 1, an inner mounting housing 101, a charging head 102 mounted at the bottom of the mounting housing 101, a battery 103 and a circuit board 104 mounted inside the mounting housing 101, an airflow sensor 105, a control chip 106 and an indicator light 107 mounted sequentially from bottom to top on the circuit board 104, a combustion chamber 108 mounted at the top of the circuit board 104, a heating wire 109 mounted inside the combustion chamber 108, a first magnet ring 110 mounted on the outer side of the top of the mounting housing 101, a cover 111 snapped onto the outer side of the top of the mounting housing 101, and a second magnet ring 112 mounted inside the cover 111.

[0029] Specifically, the charging head 102 is electrically connected to the battery 103.

[0030] Specifically, circuit board 104 is electrically connected to the output terminal of battery 103.

[0031] Specifically, the airflow sensor 105, control chip 106, indicator light 107, and heating wire 109 are all electrically connected to the circuit board 104.

[0032] Specifically, the top of the first magnet ring 110 is magnetically connected to the bottom of the second magnet ring 112.

[0033] Specifically, one end of the indicator light 107 passes through the mounting housing 101 and the outer casing 1 and extends to the outside of the outer casing 1.

[0034] Specifically, a connecting ring 113 is fixedly connected to the top of the shell cover 111, and multiple hollow ventilation holes are opened at the bottom of the combustion chamber 108.

[0035] With the above technical solution, when a tinderbox needs to be used, the user only needs to gently pull open the cover 111. Since the cover 111 is magnetically connected by the first magnetic ring 110 and the second magnetic ring 112, it is very convenient and quick to open. The internal wiring connections of the charging head 102, battery 103, circuit board 104, airflow sensor 105, control chip 106, indicator light 107, and heating wire 109 are all existing technologies known to those skilled in the art, and will not be described in detail here. After opening the cover 111, the user can direct the fire... When air is blown into combustion chamber 108, the airflow enters the mounting housing 101 through multiple perforated ventilation holes at the bottom of combustion chamber 108. The airflow sensor 105 detects the change in airflow and transmits the signal to control chip 106. Control chip 106 then triggers the heating wire 109 on circuit board 104 to heat up. The heating wire 109, located inside combustion chamber 108, ignites the combustible material inside combustion chamber 108, thus producing a flame. The heating wire 109 inside combustion chamber 108 operates... After a period of time, the control chip 106 automatically turns off the heating wire 109. When charging is needed, it connects to an external power source through the charging head 102 at the bottom to charge the battery 103 inside the mounting housing 101. The charging head 102 is electrically connected to the battery 103 to ensure that electrical energy can be effectively stored during charging. The indicator light 107 is electrically connected to the circuit board 104 to display the working status of the tinder. For example, the indicator light 107 may show red when charging and green when fully charged. When igniting, the indicator light 107 may flash or show other colors to indicate the current status to the user. One end of the indicator light 107 passes through the mounting housing 101 and the outer shell 1, so the user can see the status of the indicator light 107 intuitively. After use, the user only needs to bring the cover 111 close to the outer shell 1, and the first magnetic ring 110 and the second magnetic ring 112 will automatically magnetically close, ensuring that the cover 111 is tightly closed to prevent flame leakage or dust from entering. Opening and closing by magnetic attraction makes operation more convenient and saves time, making it especially suitable for quick use in emergency situations.
