[0052] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0053] This invention provides a portable ignition device, the structural schematic diagram of which is shown in its unused state. Figure 1 As shown in the diagram, the structural schematic diagram in the usage state is as follows: Figure 2 As shown, the cross-sectional structure diagram in its unused state is as follows: Figure 3 As shown in the diagram, the cross-sectional structure in the usage state is as follows: Figure 4As shown, the portable ignition device includes: a main body 1, a propulsion assembly 2, an ignition assembly 3, a power storage assembly 4, and a solar cell chip 5.

[0054] The body 1 is hollow inside, the energy storage component 4 is installed inside the body 1, and the ignition component 3 is movably installed inside the body 1.

[0055] The solar cell chip 5 is mounted on the main body 1 and is electrically connected to the energy storage component 4;

[0056] The propulsion component 2 is movably mounted on the main body 1 and mechanically connected to the ignition component 3;

[0057] The portable ignition device is configured such that when the propulsion component 2 is pushed upward, the propulsion component 2 causes the ignition component 3 to extend out of the body 1 and makes the ignition component 3 electrically connected to the energy storage component 4.

[0058] It should be noted that the upward push mentioned here refers to the push in the direction of the ignition component 3.

[0059] The working principle of the portable ignition device in this embodiment of the invention is as follows:

[0060] The solar cell chip 5 set on the main body 1 receives solar radiation to convert solar energy into electrical energy, so that the generated electrical energy can be continuously stored in the energy storage component 4.

[0061] When the portable ignition device is needed, push the propulsion component 2 upward. The propulsion component 2 can drive the ignition component 3 to extend out of the body 1 and make the ignition component 3 connected to the energy storage component 4. The energy stored in the energy storage component 4 is used to heat the ignition component 3. After the ignition component 3 comes into contact with the external material, it can ignite it.

[0062] Therefore, the portable ignition device of this invention realizes a portable ignition method using solar energy as the ignition energy source. This ignition method is not only easy to operate, but also safe, environmentally friendly and sustainable.

[0063] The following describes the various components and their functions of the portable ignition device provided in the embodiments of the present invention:

[0064] As for the body 1, the body 1 is the main structure of the embodiment of the present invention, which plays the role of supporting and fixing other components. Considering the portable nature of the ignition device, the size of the body 1 should not be too large. At the same time, the body 1 can be made of materials such as organic materials or alloys that are lightweight, corrosion-resistant, and extrusion-resistant.

[0065] The following is an example of the structure of ontology 1:

[0066] like Figure 1 or Figure 2As shown, the main body 1 may include a cylinder 101 and a cover plate 102, wherein,

[0067] The cover plate 102 is placed on the first end port of the body 1 and is mechanically connected to the cylinder 101 through the hinge mechanism 103. The ignition assembly 3 extends out of the body 1 through the first end port.

[0068] The cylinder 101 facilitates the installation, fixing, and protection of other components; the cover plate 102, together with the cylinder 101, can protect the ignition assembly 3.

[0069] Specifically, when the ignition device is not in use, the cover plate 102 covers the first end port, serving to prevent dust and protect the ignition assembly 3; when the ignition device is used for ignition operation, the ignition assembly 3 pushes open the cover plate 102, allowing the ignition assembly 3 to come into contact with external materials.

[0070] It is understandable that the hinge mechanism 103 can be a spring hinge, such as... Figure 4 As shown, when the cover plate 102 is placed over the first end port, the included angle between the two ends of the spring hinge is 90°, and it is in a normal state where it is neither stretched nor compressed. When the cover plate 102 is pushed open by the ignition assembly 3 and is no longer placed over the first end port, the spring hinge is stretched by the thrust of the ignition assembly 3, so that the included angle between its two ends is greater than 90°. When the ignition assembly 3 retracts into the body 1, due to the disappearance of the external force, the spring hinge returns to its original state under the action of its own elasticity, and the included angle between its two ends is still 90°. The cover plate 102 is placed over the first end port again.

[0071] As for propulsion component 2, it plays a connecting and driving role. The operator can push propulsion component 2 to push ignition component 3.

[0072] Specifically, the actuating component 2 includes a sliding sleeve 201 and a connector 202, wherein,

[0073] A sliding sleeve 201 is fitted onto the body 1, and a groove is provided on the body 1. One end of the connector 202 is mechanically connected to the ignition assembly 3, and the other end of the connector 202 extends out of the groove and is mechanically connected to the sliding sleeve 201. Figure 3 or Figure 4 or Figure 5 As shown.

[0074] Furthermore, the connector 202 may include a first part and a second part connected together. The first part is disposed inside the body 1 and connected to the ignition assembly 3; the second part extends out of the groove and is connected to the sliding sleeve 201.

[0075] With this configuration, the operator can push the sliding sleeve 201, which in turn drives the connector 202. The connector 202 then drives the ignition assembly 3 to move, allowing the ignition assembly 3 to extend out of the body 1 through the first end port and ignite the external material upon contact. This makes the operation simple and convenient.

[0076] Meanwhile, since the ignition assembly 3 emits a large amount of heat during electric heating, in order to prevent the heat emitted by the ignition assembly 3 from affecting the normal operation of the energy storage assembly 4 and the solar cell chip 5, the propulsion assembly 2 also includes a heat insulation plate 203, such as... Figure 3 or Figure 4 or Figure 5 As shown, the heat insulation plate is movably disposed inside the main body 1 and mechanically connected between the ignition assembly 3 and the first part. The heat insulation plate 203 can isolate the heat emitted by the ignition assembly 3.

[0077] Regarding the installation of the heat insulation plate 203, in order to enable its movement within the body 1, in one possible implementation, strip-shaped protrusions can be provided on the inner wall of the body 1, and a first sliding groove can be provided on the side edge of the heat insulation plate 203, such as... Figure 3 or Figure 4 or Figure 5 As shown, the first sliding groove can move relative to the protrusion, thereby enabling the heat insulation plate 203 to move within the body 1; correspondingly, in another possible embodiment, a second sliding groove can be provided on the inner wall of the body 1, and a protruding ring is provided on the side edge of the heat insulation plate 203. The protruding ring can move relative to the second sliding groove, thereby enabling the heat insulation plate 203 to move within the body 1.

[0078] Based on the above structure, the first sliding groove and the protrusion or the convex ring and the second sliding groove are engaged in a locking fit, so that a certain external force is required to make the first sliding groove and the protrusion move relative to each other or the convex ring and the first sliding groove move relative to each other, thereby driving the ignition assembly 3 to extend out of the body 1. This can prevent the heat insulation plate 203 from moving too fast in the body 1, causing frequent electrical conduction between the ignition assembly 3 and the energy storage assembly 4, which would affect the service life of the energy storage assembly 4.

[0079] Furthermore, to facilitate the retraction of the ignition assembly 3 back into the main body 1, the propulsion assembly 2 may also include a return spring 204, such as... Figure 3 or Figure 4 or Figure 5As shown, the return spring 204 is mechanically connected to the second part and is set in the groove of the recess. When the portable ignition device is needed to ignite external materials, the return spring 204 is compressed when the sliding sleeve 201 is pushed upward. When the portable ignition device is no longer needed, the compressed return spring 204 returns to its original state. Under the elastic force of the return spring 204, the second part is pushed downward, which drives the ignition assembly 3 to be stored back into the body 1 and disconnects the electrical conduction between the ignition assembly 3 and the energy storage assembly 4.

[0080] As for the energy storage component 4, it plays the role of storing electricity and providing the electrical energy required for the electric heating of the ignition component 3.

[0081] Specifically, the energy storage component 4 includes a charging circuit 401 and a battery 402, such as Figure 3 or Figure 4 or Figure 5 As shown, where,

[0082] The solar cell chip 5 is electrically connected to the battery 402 via the charging circuit 401.

[0083] When the solar cell chip 5 converts the received solar energy into electrical energy, the generated electrical energy can enter the battery 402 through the charging circuit 401, and the input voltage can be controlled by the charging circuit 401.

[0084] It should be noted that battery 402 can be a lithium battery or other types of batteries, as long as they can be placed inside the main body 1 to store electricity.

[0085] In this embodiment of the invention, battery 402 is an 18650 cylindrical lithium battery.

[0086] Furthermore, the energy storage component 4 may also include a boost circuit 403, such as Figure 3 or Figure 4 or Figure 5 As shown, where,

[0087] The boost circuit 403 is located inside the main body 1 and is electrically connected between the solar cell chip 5 and the charging circuit 401.

[0088] The boost circuit 403 can regulate and adjust the low-voltage DC power generated by the solar cell chip 5 and then send it to the charging circuit 401, which in turn sends it to the battery 402. This allows the battery 402 to continuously receive a stable supply of electrical energy, which helps protect the battery 402 and extend its service life.

[0089] As for the ignition component 3, it plays the role of igniting external materials and is a key component of the portable ignition device in this embodiment of the invention.

[0090] like Figure 3 or Figure 4 or Figure 5 As shown, the ignition assembly 3 includes a housing 301 and a heating wire 302 and an energizer switch 303 disposed within the housing 301, as follows: Figure 3 or Figure 4 or Figure 5 As shown, where,

[0091] The housing 301 is mechanically connected to the propulsion assembly 2, and the power switch 303 is electrically connected between the heating wire 302 and the battery 402.

[0092] The heating wire 302 is located near the first end port of the housing 301.

[0093] Furthermore, the housing 301 can be connected to the connector 202 within the propulsion assembly 2.

[0094] In this embodiment of the invention, the heating wire 302 can be made of a metal wire with low resistance. When the heating wire 302 is electrically connected to the battery 402, according to Ohm's law, the resistance will generate heat. After the heat accumulates and the temperature rises to a certain level, the external material will come into contact with the heating wire 302, and the heating wire 302 can ignite it.

[0095] It should be noted that the heating wire 302 can be coiled to increase the usable area; at the same time, a corrosion-resistant coating is sprayed on its surface to prevent the heating wire 302 from being corroded and affecting the heating.

[0096] As for the solar cell chip 5, it plays the role of converting solar energy into electrical energy and is also a key component of the embodiments of the present invention.

[0097] In one possible implementation, multiple channels are formed in the wall of body 1, such as... Figure 1 or Figure 2 As shown, the solar cell chip 5 is a flexible battery chip. The solar cell chip 5 is attached to the inside of the wall and is arranged corresponding to the channel.

[0098] This configuration not only facilitates the installation and protection of the solar cell chip 5, but also allows the solar cell chip 5 to obtain solar energy through the channel.

[0099] It should be noted that the solar cell chips used here are semiconductor devices with photoelectric effect. The PN junction of the semiconductor can generate an unstable low-voltage current after being illuminated, and one or more of them can be used.

[0100] The flexible battery chip here is a flexible thin-film power generation material that can be bent and rolled and sealed with water-blocking material. It has the characteristics of vibration resistance, impact resistance, damp heat resistance, low temperature resistance, and can generate electricity even in low light. Its outer side is itself equipped with a transparent protective layer through sealant.

[0101] For each channel, those skilled in the art will understand that it is sufficient to ensure that each channel has light transmission properties.

[0102] For example, each channel may be without glass or may be equipped with transparent glass or plexiglass; however, this is not specifically limited in the embodiments of the present invention.

[0103] In another possible implementation, the solar cell chip 5 is a flexible battery chip, which is mounted around the iron on the outer wall of the body 1.

[0104] Because the solar cell 5 is flexible, it can be attached or laminated onto the cylinder wall. In this implementation, the solar cell 5 has a sufficiently large light-receiving area, ensuring the acquisition of solar energy.

[0105] Based on the portable ignition device of the present invention mentioned above, in terms of structural configuration, on the one hand, a charging port 104 can be provided on the main body 1, and the charging port 104 is electrically connected to the energy storage component 4, so that the energy storage component 4 can also be charged by an external power source.

[0106] In this embodiment of the invention, the charging port 104 can be connected to the charging circuit 401 in the energy storage component 4, and the charging circuit 401 supplies power to the battery 402.

[0107] For example, battery 402 can be charged using a 5V power supply.

[0108] It should be noted that when the battery 402 is not being charged using the charging port 104, a dust plug can be installed at the charging port 104 to prevent dust from falling into the charging port 104 and affecting its use.

[0109] In terms of structural configuration, the portable ignition device also includes a piezoelectric component 6, which comprises a piezoelectric ceramic 601, an elastic damper 602, and a plunger 603. Its structural schematic diagram when not in use is shown below. Figure 3 or Figure 4 As shown, its structural diagram in use is as follows: Figure 5 As shown, where,

[0110] A piezoelectric ceramic 601 is disposed inside the body 1, and a plunger 603 is disposed at the second end port of the body 1, wherein the second end port is opposite to the first end port.

[0111] The elastic damper 602 is mechanically connected between the piezoelectric ceramic 601 and the plunger 603;

[0112] The piezoelectric ceramic 601 is electrically connected to the energy storage component 4.

[0113] By repeatedly pressing the plunger 603, the mechanical stress generated during pressing is continuously transmitted to the piezoelectric ceramic 601 through the elastic damper 602. This causes the positive and negative charge centers inside the piezoelectric ceramic 601 to shift relative to each other and become polarized. This results in the appearance of bound charges with opposite signs on the surfaces at both ends of the piezoelectric ceramic 601, which continuously accumulates charge, thus converting mechanical energy into electrical energy. In turn, the piezoelectric ceramic 601 is electrically connected to the energy storage component 4, allowing the energy storage component 4 to be charged by generating electricity through the piezoelectric ceramic 601.

[0114] In this embodiment of the invention, the piezoelectric ceramic 601 can be connected to the charging circuit 401 in the energy storage component 4, and the charging circuit 401 supplies power to the battery 402.

[0115] It should be noted that the frequency of charge change is related to the frequency of application of external mechanical stress. When the frequency of application of external mechanical stress is fast, the frequency of charge change is also fast; when the frequency of application of external mechanical stress is slow, the frequency of charge change is also slow.

[0116] Furthermore, the piezoelectric component 6 also includes a rectifier and filter circuit 604, which is disposed within the body 1. The rectifier and filter circuit 603 is electrically connected between the piezoelectric ceramic 601 and the energy storage component 4.

[0117] The rectifier filter circuit 604 includes connected diodes and capacitors, and the capacitors are low-loss, high-voltage capacitors.

[0118] In this embodiment of the invention, the rectifier filter circuit 603 can be electrically connected between the piezoelectric ceramic 601 and the charging circuit 401 in the energy storage component 4, and supply power to the battery 402 through the charging circuit 401.

[0119] By filtering and storing the energy generated by the piezoelectric ceramic 601 with its variable voltage and frequency into a capacitor, and then using a diode for rectification, the electrical energy generated by the piezoelectric ceramic 601 can be rectified and filtered before entering the battery 402 through the charging circuit 401.

[0120] After rectifying and filtering the electrical energy generated by the piezoelectric ceramic 601, in this embodiment of the invention, the piezoelectric component 6 also includes a step-down circuit 605, which is disposed in the body 1 and electrically connected between the rectifier and filter circuit 604 and the energy storage component 4.

[0121] In this embodiment of the invention, the rectifier filter circuit 604 can be connected to the charging circuit 401 in the energy storage component 4.

[0122] This configuration allows the voltage generated by the rectifier and filter circuit 604 to be stepped down and adjusted by the step-down circuit 605 before being delivered to the energy storage component 4. This ensures that the battery 402 in the energy storage component 4 receives a continuous and stable supply of electrical energy, which helps protect the battery 402 and extend its service life.

[0123] Meanwhile, in order to achieve electrical isolation between the rectifier filter circuit 604, the step-down circuit 605 and the piezoelectric ceramic 601, the piezoelectric component may also include an insulating plate 606. The insulating plate 606 is made of rigid organic material. The insulating plate 606 is disposed in the body 1 and is mechanically connected to the piezoelectric ceramic 601. It not only plays the role of electrical isolation between the circuit and the piezoelectric ceramic 601, but also plays the role of buffering external mechanical stress.

[0124] The three charging methods mentioned above all require the battery 402 to be charged through the charging circuit 401. To avoid mutual interference between the three charging methods and to prevent the simultaneous operation of the three charging methods from affecting the use of the battery 402, the charging circuit 401 uses a DC / DC circuit design to achieve unidirectional isolation of the three charging methods.

[0125] Based on this, the portable ignition device also includes a protection component 7, which includes an over-temperature protection circuit 701 and an over-voltage protection circuit 702, wherein...

[0126] The over-temperature protection circuit 701 is electrically connected inside the ignition assembly 3;

[0127] The overvoltage protection circuit 702 is located inside the main body 1 and is electrically connected to the energy storage component 4.

[0128] In this embodiment of the invention, the over-temperature protection circuit 701 can be electrically connected between the heating wire 302 and the power switch 303; the over-voltage protection circuit 702 is disposed in the body 1 and is electrically connected to the charging circuit 401 in the energy storage component 4.

[0129] By employing an over-temperature protection circuit 701 equipped with a temperature relay, when the temperature of the heating wire 302 exceeds the preset temperature, the bimetallic material inside the temperature relay deforms, and the over-temperature protection circuit 701 controls the power switch 303 to close, ensuring that the temperature of the heating wire 302 does not continue to rise, thereby protecting the battery 402; by employing an over-voltage protection circuit 702 equipped with a voltage comparator, when the charging voltage exceeds the protection voltage set inside the over-voltage protection circuit 702, the over-voltage protection circuit 702 disconnects the electrical connection with the charging circuit 401.

[0130] It should be noted that the protection component 7 also includes an indicator light 703. When the overvoltage protection circuit 702 disconnects the electrical connection with the charging circuit 401, the indicator light 703 is electrically connected to the charging circuit 401, which can remind the operator.

[0131] In practical use, the portable ignition device of this embodiment can be placed in a place where it can receive sunlight, and the solar cell chip 5 can be used to receive solar energy to convert solar energy into electrical energy to charge the battery 402; or the operator can repeatedly press the plunger 603 to convert mechanical energy into electrical energy using the piezoelectric effect of the piezoelectric ceramic 601 to charge the battery 402; or the external power supply can be plugged into the charging port 104 to directly charge the battery 402.

[0132] After the battery 402 is charged, when the portable ignition device of this embodiment of the invention is needed, the sliding sleeve 201 can be pushed upward, so that the sliding sleeve 201 drives the connector 202, the connector 202 drives the heat insulation plate 203, the heat insulation plate 203 drives the housing 301, so that the heating wire 302 extends out of the body 1 and the power switch 303 is turned on, the heating wire 302 is connected to the battery 402, and the electrical energy stored in the battery 402 is used to heat the heating wire 302, so that the heated heating wire 302 can ignite the external material after contacting it, thus achieving the purpose of ignition.

[0133] The above description is merely for the purpose of enabling those skilled in the art to understand the technical solutions of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
