Description

An ignition device with a cold light firework effect Technical Field

[0001] This invention relates to an ignition device capable of producing a cold light firework effect. Background Technology

[0002] The cold light fireworks effect created by igniting and spraying combustible powder is widely used due to its high safety.

[0003] In the early stages of development, we have developed a series of devices capable of producing the aforementioned fireworks effects, as detailed in the following Chinese patent documents: CN208968375U (authorization announcement number) discloses a powder combustion and ejection device that simulates cold light fireworks effects; CN 221505822U (authorization announcement number) discloses a multi-flame color fireworks powder combustion and ejection device; CN 221945035U (authorization announcement number) discloses a handheld fireworks display device based on powder combustion and ejection; and CN 222068500U (authorization announcement number) discloses a fireworks device based on powder combustion and ejection.

[0004] Currently, traditional ignition devices (such as lighters, windproof lighters, direct-fire lighters, flamethrowers, and flame guns) are mainly used for igniting items like cigarettes and candles, offering limited functionality and lacking entertainment value. With evolving user needs, there is an urgent need for an innovative design that can not only fulfill the basic ignition function but also enhance the user experience through added entertainment features. In existing technologies, cold-light fireworks have been applied to stage effects and other fields, but they have not yet been effectively integrated with portable ignition devices. This invention improves the structure of the ignition device, integrating the cold-light fireworks emission function into the device body, achieving functional fusion. Summary of the Invention

[0005] To address the aforementioned drawbacks, the technical problem this invention aims to solve is to provide an ignition device that not only performs the ignition function but also produces a cold-light firework effect during ignition, increasing its appeal. To solve this technical problem, the present invention provides an ignition device with a cold-light firework effect, comprising an ignition device body. The ignition device body includes a combustion chamber, a mixing chamber, a fuel assembly, and an ignition device. Fuel from the fuel assembly is injected into the mixing chamber and mixes with air to form a mixed airflow, which is ignited by the ignition device. The device also includes a powder storage device for storing combustible powder. The powder storage device is positioned near the area through which the mixed airflow passes, and the outlet of the powder storage device is connected to the mixing chamber and / or the combustion chamber, allowing the combustible powder to mix and burn with the mixed airflow.

[0006] The beneficial effect of this invention is that when the fuel of the ignition device body is ejected at high speed, the surrounding air and powder are drawn in by the suction force of the airflow. The combustible powder is fully mixed with the air and fuel gas and then combusted and ejected, which can present the star effect of combustible powder combustion and the flame (or flame) of the ignition device. It completely simulates the fireworks effect presented by cold light fireworks and cleverly realizes the effective integration of the cold light fireworks effect and the portable ignition device.

[0007] The area through which the mixed airflow passes can be the air inlet or surrounding area of ​​the mixing chamber, the airflow channel at or around the inlet, or the airflow channel at or around the outlet of the combustion chamber. In one embodiment, the outlet of the powder storage device is located at the air inlet of the mixing chamber. This is beneficial for optimizing the cold light fireworks' emission effect.

[0008] In one embodiment, the powder storage device is provided with a feeding mechanism that conveys combustible powder to the discharge port. The feeding mechanism is selected from a gravity feeding mechanism, a manual or electric screw feeding mechanism, and the screw feeding mechanism is connected to the discharge port of the powder storage device.

[0009] In one embodiment, the powder storage device and the ignition button of the ignition device are equipped with a linked feeding mechanism. Preferably, the linked feeding mechanism includes a screw conveyor mechanism that transports combustible powder toward the discharge port, and the screw conveyor mechanism is connected to the discharge port of the powder storage device's hopper; the screw of the screw conveyor mechanism is connected to the button of the ignition device through a ratchet mechanism and a transmission assembly, and when the button is pressed, the button drives the screw to rotate unidirectionally through the transmission assembly and the ratchet mechanism. By using a linked feeding mechanism, pressing the button simultaneously triggers powder conveying, combining the three actions of gas delivery, ignition, and powder conveying into one. This facilitates use and naturally completes the timing coordination of the three actions.

[0010] In one embodiment, the feeding mechanism is equipped with a clutch mechanism. When the clutch mechanism is engaged, the screw of the feeding mechanism does not rotate. Combustible powder will not enter the mixing chamber, and no cold light firework effect will be produced; it can be used solely as an ignition device.

[0011] In one embodiment, the powder storage device is an annular hopper with a centrally located discharge pipe. The inner wall of the annular hopper is fitted onto the wall of the discharge pipe and can rotate around the discharge pipe. The inner wall and the pipe wall are respectively provided with inner holes and outer holes. When the annular hopper rotates to the point where the inner holes and outer holes coincide, it forms a discharge channel for discharging material toward the inner cavity of the discharge pipe. The lower end of the discharge pipe is a connecting port, and the upper end leads to the outside.

[0012] Preferably, multiple annular silos are stacked along the axial direction of the discharge pipe. Each layer of powder silos can be loaded with different types or flame colors of combustible powder, thus supporting the combined firing of multiple combustible powders.

[0013] In one embodiment, the ignition device body is a lighter.

[0036] Example 1: Refer to Figures 1, 2, 3, 4, and 5, which illustrate a specific structure of the present invention. Ignition devices (such as lighters, windproof lighters, direct-fire lighters, spray guns, flamethrowers, etc.) have similar structures. The example uses a lighter as an example. As shown in Figure 3, this is a lighter with a cold-light fireworks effect. The lighter includes a nozzle 4 of the fuel assembly 10, a mixing chamber 2, an air inlet 3, and a combustion chamber 1. Generally, two air inlets 3 are arranged on opposite sides of the mixing chamber 2. Some lighters do not have a clearly defined combustion chamber 1 and lack a burner 5—as shown in Figure 1, the upper part of the mixing chamber 2 is considered the combustion chamber 1, as shown in Figure 1. The lighter also includes an ignition device consisting of an ignition button 8 and an ignition assembly 9. The wire end of the ignition assembly 9 is close to the combustion chamber 1 for ignition. When the ignition button 8 is pressed, the valve of the fuel assembly 10 is opened in conjunction, so that the fuel stored in the fuel assembly 10 is sprayed out at high speed from the nozzle 4 into the mixing chamber 2, where it mixes with the air entering through the air inlet 3 to form a mixed airflow. The mixed airflow is ignited by the ignition device in the combustion chamber 1.

[0037] The present invention also includes a powder storage device 7 for storing combustible powder, the powder storage device 7 being disposed near the area through which the mixed airflow passes, and the outlet of the powder storage device 7 being connected to the mixing chamber and / or combustion chamber so that the combustible powder is mixed and burned with the mixed airflow.

[0038] The preferred locations of the discharge ports of the powder storage device 7 are shown in Figures 1 and 2. The discharge ports of the powder storage device 7 are located near the area through which the mixed airflow (including the airflow before and after mixing) passes. The suction force of the mixed airflow draws the combustible powder located at the discharge port into the mixed airflow, allowing the combustible powder to mix and burn with air and fuel gas, and then be ejected from the nozzle at the top of the combustion chamber 1, creating a cold light firework effect. Experiments have shown that selecting the discharge ports of the powder storage device at or near each of the locations A shown in the figures effectively achieves the purpose of the invention. Location A can be the area around the mixing chamber 2, the air inlet 3, or the airflow channel around the air inlet 3, inside the combustion chamber 1, outside the combustion chamber 1, or on or around the airflow channel of the nozzle 6 of the combustion chamber 1.

[0039] The powder storage device 7 contains combustible powders such as titanium, iron, copper, aluminum, barium salts, strontium salts, sodium salts, copper salts, wood powder, spice powder, and pharmaceutical powder, etc. The combustible powder raw materials are selected according to the air flow rate and the pressure of liquids and gases. Experiments have shown that combustible powders between 10 and 1000 mesh are acceptable.

[0040] In this example, the discharge port of the powder storage device 7 is located on an air inlet 3 of the mixing chamber 2, and the discharge port is connected to the air inlet 3. This does not affect the air intake, and the powder adsorption effect is relatively strong, which is beneficial to optimizing the cold light fireworks spraying effect.

[0041] In the example, as shown in Figure 5, the powder storage device 7 has a hopper 701 arranged around a central cavity 703. One end of the cavity 703 is the discharge port 704, and the other end is an air inlet 702. The discharge port 704 connects to an air inlet 3 of the mixing chamber 2. Powder falling from the hopper 701 into the cavity 703 is drawn away by the mixed airflow through the discharge port 704 and the air inlet 3. The air inlet 702 replenishes air from the outside to facilitate smooth airflow.

[0042] In other embodiments, the powder storage device 7 can also adopt other structures, such as the hopper 706 shown in Figure 4, with a discharge port 707 at one end connecting to the air inlet 3. Outside air can be supplemented from the gap between the discharge port 707 and the air inlet 3, or an additional channel for outside air to enter the hopper can be provided on the hopper, such as an air supply port 705.

[0043] Example 2: Referring to Figure 6, in this example, the powder storage device is equipped with a feeding mechanism that conveys combustible powder to the discharge port. The feeding mechanism employs a gravity-feeding mechanism, which includes a first hopper 22 positioned above the discharge port. The first hopper 22 is connected to the discharge port via a feeding pipe 23, and a hopper switch 21 is also provided. The powder is fed to the discharge port using its own weight. The powder storage device described in Example 1 also belongs to a type of feeding mechanism employing a gravity-feeding mechanism.

[0044] Example 3: Referring to Figures 7 and 8, in this example, the powder storage device employs a manually operated screw feeding mechanism. This mechanism includes a second hopper 31 and a screw feeding mechanism 33. The screw feeding mechanism 33 includes a screw rod installed within a housing 333. The housing 333 connects to the discharge port of the second hopper 31. A manual knob 32 is connected to the screw rod of the screw feeding mechanism 33. Rotating the manual knob 32 conveys the combustible powder in the second hopper 31 to the discharge port. The portion of the screw rod from the end near the manual knob 32 to the discharge port is a shaft portion 331. The rear end of the shaft portion 331 is a threaded groove portion 332 for conveying combustible powder 35, preventing combustible powder from flowing out from the end near the manual knob 32 when the screw rod rotates in the opposite direction. The hopper cover 34 facilitates the addition of combustible powder 35.

[0045] Example 4: Referring to Figure 9, in this example, the powder storage device uses an electrically powered screw feeding mechanism. This mechanism includes a third hopper 41 and a screw feeding mechanism 42, with the screw feeding mechanism 42 connected to the discharge port of the third hopper 41. A motor 43 is connected to the screw of the screw feeding mechanism 42; turning on the motor 43 transports the combustion powder in the third hopper 41 to the discharge port. The nozzle 4 and the mixing chamber 2 are designed to be disconnected, with the disconnected part being an air inlet 3. This allows for more flexible placement of the screw feeding mechanism 42 and facilitates the arrangement of multiple sets of screw feeding mechanisms 42, resulting in a larger airflow.

[0046] Example 5: Referring to Figure 10, the difference from Example 4 is that, in addition to the motor 51 driving the screw feeding mechanism, an integrated sound and light module powered by battery 54 is also included. The sound and light module includes an LED light 52, a speaker 53, a control circuit, and a pre-recorded sound unit, synchronously triggering light and sound effects. The light effect is similar to the flashing pattern of a miniature LED light. The lighter body has a transparent or semi-transparent shell, making the light effect more pronounced. The sound effect is used to play music such as "Happy Birthday," "Wishing You Prosperity," "Celebrating Victory," and the sound of fireworks exploding when the lighter is ignited.

[0047] Example 6: Referring to Figure 11, in this example, the powder storage device and the ignition button of the ignition device are equipped with a linked feeding mechanism. This linked feeding mechanism includes a screw conveyor that transports combustible powder toward the discharge port 60. The screw conveyor is connected to the discharge port of the powder storage device's hopper. The screw 68 of the screw conveyor is connected to the button 61 of the ignition device via a ratchet mechanism and a transmission assembly. In this example, the ratchet mechanism consists of a pawl 62 connected to the button 61 and a ratchet 63 connected to the screw 68. When the button 61 is pressed, the pawl 62 actuates the ratchet 63 below, causing the screw 68 to rotate unidirectionally, transporting combustible powder toward the discharge port 60.

[0048] In a lighter, pressing button 61 of the ignition device simultaneously triggers both ignition and gas delivery:

[0049] In the example, when button 61 is pressed, the A end of lever 69 is pressed down, which causes lever 69 to rotate along fulcrum 67. The B end of lever 69 moves upward to open the fuel switch of the fuel assembly. The fuel is vaporized and sprayed out at high speed from the nozzle, adsorbing combustible powder and air to form a mixed airflow.

[0050] At the same time, when button 61 is pressed, the ignition device 65 is pressed down to ignite the piezoelectric ignition, and the mixture is ignited in the combustion chamber through wire 651.

[0051] Therefore, the linked feeding mechanism allows the pressing of button 61 to simultaneously perform the three actions of air supply, ignition, and powder conveying. This facilitates use and naturally coordinates the timing of the three actions.

[0052] In the example, the feeding mechanism is equipped with a manual clutch mechanism. Specifically, the pawl 62 is connected to the button 61 via a rotating shaft 621. The pawl 62 can be manually displaced axially along the rotating shaft 621, causing the pawl 62 to misalign with the ratchet 63 to interrupt transmission and achieve a clutch effect. When the button 61 is pressed, the ratchet 63 and its spiral screw 68 do not operate, thus not supplying combustible powder and achieving a single ignition function.

[0053] Other clutch mechanisms that interrupt transmission can also be used in other implementations.

[0054] In other embodiments, such as the electric screw conveyor mechanism, a clutch mechanism can be used to interrupt the transmission between the motor and the screw. When the clutch mechanism is engaged, the electric screw does not rotate. Combustible powder will not enter the mixing chamber, and no cold light firework effect will be produced; it can be used solely as an ignition device.

[0055] Example 7: Referring to Figure 12, the difference from Example 6 is that the spiral feeding mechanism has both a manual mode and a linked feeding mode. A manual wheel 71 and a ratchet 72 are coaxially mounted on the spiral screw 70 of the spiral feeding mechanism. The ratchet 72 is connected to the button of the ignition device via a pawl and a transmission assembly (same as in Example 6, so it will not be described again). The manual wheel 71 is partially located outside the lighter body. After pressing the button to ignite, while keeping the button pressed, the manual wheel 71 can be manually continuously turned, thereby causing the spiral feeding mechanism to continuously feed material and maintain the cold light firework effect.

[0056] Example 8: Referring to Figures 13, 14, and 15, the powder storage device is an annular hopper 802 with a centrally located discharge pipe 801. The inner wall 803 of the annular hopper 802 is fitted onto the pipe wall 804 of the discharge pipe 801 and can rotate around the discharge pipe 801. The inner wall 803 and the pipe wall 804 are respectively provided with an inner hole 805 and an outer hole 806. When the annular hopper 802 rotates to the point where the inner hole and the outer hole coincide, it forms a discharge channel for discharging material toward the inner cavity of the discharge pipe 801. The lower end of the discharge pipe 801 is a connecting port 807, and the upper end 808 leads to the outside.

[0057] The example also includes a stirring component 809 to agitate the powder for easier feeding and a hopper cover 810.

[0058] When the annular hopper 802 is installed above the nozzle of the combustion chamber of the ignition device body: the interface 807 is connected to the nozzle, and the lower port 808 is the injection port of the mixed airflow. The annular hopper 802 can be installed by inserting the interface 807 into the nozzle, or by magnetic attraction or snap-fit. When the combustible powder in the annular hopper 802 falls from the discharge channel into the discharge pipe 801, it is ignited by the flame of the mixed airflow ejected from the nozzle and ejected from the lower port 808, creating a cold light firework effect.

[0059] When the annular hopper 802 is connected to the discharge port: the interface 807 is connected to the discharge port, and the upper port 808 is the air supply port. After the combustible powder in the annular hopper 802 falls from the discharge channel into the discharge pipe 801, it is adsorbed by the high-speed combustion gas to form a mixed airflow.

[0060] In the example, two annular hoppers 802 are stacked along the axial direction of the discharge pipe 801. Each annular hopper 802 is loaded with different types or flame colors of combustible powder, thus supporting the combined ejection of multiple combustible powders.

[0061] In the example, the single-layer powder hopper 802 can also be divided into compartments to load different types or flame colors of combustible powders, and can also support the combined firing of multiple combustible powders.

[0062] In other implementations, safety protection devices may be included, such as a flame adjustment knob to control the flame size, a child lock to prevent accidental operation, and overheat protection to automatically cut off the fuel supply to prevent overheating.

[0063] The embodiments of the present invention disclosed above are merely illustrative of the invention. The embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and describes these embodiments in conjunction with the accompanying drawings to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. However, the invention can be implemented in many ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the invention. Therefore, the invention is limited only by the claims and their full scope and equivalents, and not by the specific embodiments disclosed.
