[0034] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the detailed implementation manners of the present utility model are now described in detail with reference to the accompanying drawings.

[0035] As Figures 1 to 3 shown, the lighter device provided in an embodiment of the present utility model includes a lighter 1 and a lighter protection case. The lighter protection case wraps the lighter 1 to protect the lighter 1 from being scratched, contaminated, and prevent the metallic lighter 1 from being too cold to hold in cold weather.

[0036] As Figure 3 shown, the lighter 1 may include a cover body 10 and a main body 11. The cover body 10 and the main body 11 are hinged together so that the cover body 10 can be flipped relative to the main body 11 to achieve the functions of opening and closing the cover. The main body 11 is mainly used for lighting fires, and the cover body 10 can be used to protect the fire head and achieve the function of extinguishing the fire.

[0037] As Figure 1 And Figure 2As shown in the figure, the lighter protection case according to an embodiment of the present invention may include a first housing 21 and a second housing 22. The first housing 21 defines a first cavity 211 for receiving the main body 11 of the lighter 1, and the second housing 22 defines a second cavity 222 for receiving the cover 10 of the lighter 1. That is, the second housing 22 and the first housing 21 can be respectively used to sleeved on the cover 10 and the main body 11 of the lighter 1. Thus, the second housing 22 can be flipped relative to the first housing 21 as the cover 10 of the lighter 1 is flipped. It can be understood that the second housing 22 and the first housing 21 are not limited to being independent of each other, and the two can also be movably connected together.

[0038] As Figures 4 to 6 shown in the figure, the lighter protection case further includes a first light-emitting unit 3 and a second light-emitting unit 4. The first light-emitting unit 3 is disposed on the first housing 21, and the second light-emitting unit 4 is disposed on the second housing 22. The second housing 22 has an open position and a closed position. Specifically, one end of the second housing 22 and the first housing 21 may be hinged, so that the second housing 22 can be flipped relative to the first housing 21 as the cover 10 of the lighter 1 is flipped. When the rotation angle between the second housing 22 and the first housing 21 is greater than a first preset value, it can be considered that the second housing 22 is in the open position, and the lighter protection case is in the open cover state, that is, the lighter 1 is in the open cover state; when the rotation angle between the second housing 22 and the first housing 21 is less than a second preset value, or when the second housing 22 and the first housing 21 are in contact with each other, it can be considered that the second housing 22 is in the closed position, and the lighter protection case is in the closed cover state, that is, the lighter 1 is in the closed cover state.

[0039] When the second housing 22 is in the open position, the first light-emitting unit 3 is turned on and the second light-emitting unit 4 is turned off. When the second housing 22 is in the closed position, the second light-emitting unit 4 and the first light-emitting unit 3 are turned on and automatically turned off after a preset time. The preset time can be 10 seconds, 20 seconds, etc. That is, when the second housing 22 is in the open position, only the first light-emitting unit 3 at the first housing 21 is turned on, indicating that the lighter protection case is in the open cover state, that is, the lighter 1 is in the open cover state; when the second housing 22 is in the closed position, the second light-emitting unit 4 and the first light-emitting unit 3 are turned off after the preset time, indicating that the lighter protection case is in the closed cover state, that is, the lighter 1 is in the closed cover state. Thus, the lighting conditions of the lighter device in the open cover state and the closed cover state are different, which can accurately prompt the user whether the lighter 1 is in the closed cover state, and add interest to the opening and closing process of the lighter 1, improving the user experience.

[0040] As Figures 4 to 7As shown, in some embodiments, the first light-emitting unit 3 includes a control module, a first conductive terminal 33, and at least one first light-emitting element 32; the second light-emitting unit 4 includes a second conductive terminal 43 and at least one second light-emitting element 42; the lighter protective case further includes a triggering device. The first end of the second conductive terminal 43 is connected to the second light-emitting element 42, and the second end of the second conductive terminal 43 is connected to the first end of the first conductive terminal 33 when the second housing 22 is in the closed position. The second end of the first conductive terminal 33 is connected to the control module. The control module is further connected to the first light-emitting element 32 and the triggering device respectively. The triggering device generates a trigger signal when the second housing 22 is in the closed position. The control module receives the trigger signal and controls the first light-emitting element 32 and the second light-emitting element 42 to turn on for a preset time and then automatically turn off. Conversely, when the second housing 22 is in the open position, the second end of the second conductive terminal 43 is disconnected from the first end of the first conductive terminal 33. The first light-emitting element 32 turns on, and the second light-emitting element 42 turns off.

[0041] In some embodiments, the triggering device is a Hall switch (not shown). Specifically, the Hall switch can be disposed on the first housing 21, and the lighter protective case further includes a magnet (not shown) disposed on the second housing 22. The Hall switch is mechanically and / or electrically connected to the control module of the first light-emitting unit 3, and electrical signals can be transmitted between the Hall switch and the control module of the first light-emitting unit 3. When the second housing 22 is in the open position, the Hall switch and the magnet are separated from each other until the Hall switch is not affected by the magnetic field, so the Hall switch is not turned on. When the second housing 22 is in the closed position, the Hall switch and the magnet approach each other until the Hall switch is turned on. After the Hall switch is turned on, a trigger signal is generated. The control module receives the trigger signal and controls the first light-emitting element 32 and the second light-emitting element 42 to turn on for a preset time and then automatically turn off.

[0042] Alternatively, in some other embodiments, the triggering device is a mechanical switch. The mechanical switch can be disposed on the first housing 21. The mechanical switch is mechanically and / or electrically connected to the control module of the first light-emitting unit 3, and electrical signals can be transmitted between the mechanical switch and the control module of the first light-emitting unit 3. When the second housing 22 is in the open position, the mechanical switch is not turned on. When the second housing 22 is in the closed position, the mechanical switch abuts against the second housing 22 until the mechanical switch is turned on. After the mechanical switch is turned on, a trigger signal is generated. The control module receives the trigger signal and controls the first light-emitting element 32 and the second light-emitting element 42 to turn on for a preset time and then automatically turn off.

[0043] Specifically, as Figures 5 to 7As shown, in some embodiments, the first light-emitting unit 3 further includes a first circuit board 31. The control module may be a controller such as an MCU disposed on the first circuit board 31. The first circuit board 31 is disposed on the first housing 21. The first conductive terminal 33 is disposed on the first housing 21 and connected to the first circuit board 31. At least one first light-emitting element 32 is disposed on the first circuit board 31. Specifically, the first light-emitting element 32 may be an LED (light-emitting diode) mounted on the first circuit board 31. One or more first light-emitting elements 32 may be provided. And two or more of the first light-emitting elements 32 may have different colors, thereby showing lights of different colors and adding interest.

[0044] The second light-emitting unit 4 includes a second circuit board 41, a second conductive terminal 43, and at least one second light-emitting element 42. The second circuit board 41 is disposed on the second housing 22. The second conductive terminal 43 is disposed on the second housing 22 and connected to the second circuit board 41. At least one second light-emitting element 42 is disposed on the second circuit board 41. Similarly, the second light-emitting element 42 may be an LED (light-emitting diode) mounted on the second circuit board 41. One or more second light-emitting elements 42 may be provided. And two or more of the second light-emitting elements 42 may have different colors.

[0045] According to the change in the relative position between the second housing 22 and the first housing 21, the first conductive terminal 33 and the second conductive terminal 43 may be in a contact state or a non-contact (disconnected) state. Specifically, in the open position of the second housing 22 (as Figure 2 shown), since the second housing 22 and the first housing 21 are separated from each other, the first conductive terminal 33 and the second conductive terminal 43 are not in contact. At this time, only the first light-emitting element 32 is turned on, and the second light-emitting element 42 is in a de-energized off state. In the closed position of the second housing 22 (as Figure 1 shown), since the second housing 22 and the first housing 21 are close to each other, the first conductive terminal 33 and the second conductive terminal 43 are in contact. Thus, the first light-emitting element 32, the control module, the first conductive terminal 33, the second conductive terminal 43, and the second light-emitting element 42 together form a closed circuit, enabling the second light-emitting element 42 to be electrically connected to the control module on the first circuit board 31.

[0046] Specifically, a delay circuit module is designed on the first circuit board 31, and the delay circuit module can be connected to the control module, and the trigger device can be used as a trigger switch of the delay circuit module. The specific content of the delay circuit module can refer to the prior art. For example, regarding the circuit for controlling the delayed light-off of the LED light-emitting diode, an RC delay circuit (using a combination of resistors and capacitors to create a delay. The capacitor is charged through the resistor, and when the voltage reaches a certain level, the LED is lit; the delay time can be set by adjusting the value of the resistor and the capacitor), a 555 timer circuit (a multifunctional integrated circuit that can be configured to generate a monostable delay output, thereby controlling the LED to light up or go out after a specific time), a transistor delay circuit (using a transistor and a capacitor to form a Miller integration circuit to achieve delay control; after the capacitor is charged to a certain voltage, the transistor is turned on and the LED is lit) or a digital logic circuit (using digital logic gates such as NAND gates, NOR gates, etc. to design delay logic, and control the delayed light-off of the LED through different logic combinations) and the like. For example, when the second shell 22 and the first shell 21 are close to each other until the Hall switch or the mechanical switch is turned on, the Hall switch or the mechanical switch outputs a corresponding trigger signal to activate the delay circuit, thereby controlling the first light-emitting element 32 and the second light-emitting element 42 to automatically extinguish after a preset period of time.

[0047] like Figure 5 As shown, in some embodiments, the first housing 21 is further provided with a third cavity 213, the third cavity 213 is not connected to the first cavity 211, and the first light-emitting unit 3 is at least partially disposed in the third cavity 213. That is, the first light-emitting unit 3 may be entirely disposed in the third cavity 213, that is, the first circuit board 31 and all the first light-emitting elements 32 are disposed in the third cavity 213; or, some of the first light-emitting elements 32 may be disposed in the third cavity 213, and other first light-emitting elements 32 may be disposed at other positions on the first housing 21.

[0048] The lighter protective shell also includes a first cover plate 51, which is detachably connected to the first shell 21 and covers the third cavity 213, and the first cover plate 51 is provided with a first light-transmitting portion 510. The first cover plate 51 can be used as a physical barrier to protect the components in the third cavity 213. At the same time, the first light-transmitting portion 510 can be used for the light emitted by the first light-emitting element 32 to pass through, and the light emitted by the first light-emitting element 32 is blocked by other parts of the first cover plate 51 except the first light-transmitting portion 510. Therefore, from the user's perspective, it can be seen that the first light-transmitting portion 510 of the first cover plate 51 emits light, which has a decorative effect and increases the interest of the lighter protective shell. Since the first cover plate 51 is detachably connected to the first shell 21, different first cover plates 51 can be easily replaced, and different first cover plates 51 can be provided with first light-transmitting portions 510 of different shapes, presenting different decorative effects, and bringing more interesting choices.

[0049] As Figures 1 to 3 shown in the embodiment, the first light-transmitting part 510 may include a light-transmitting hole 5101 and / or a strip-shaped light-transmitting groove 5102. The light-transmitting hole 5101 is different from the strip-shaped light-transmitting groove 5102. The light-transmitting hole 5101 is generally dot-shaped or block-shaped; the strip-shaped light-transmitting groove 5102 is linear, strip-shaped, and has an obvious length and extension trajectory. The light-transmitting hole 5101 and / or the strip-shaped light-transmitting groove 5102 penetrate the first cover plate 51 along the thickness direction of the first cover plate 51, so that the light emitted by the first light-emitting element 32 is transmitted out along the thickness direction of the first cover plate 51.

[0050] Specifically, the light-transmitting hole 5101 may have a specific shape. The strip-shaped light-transmitting groove 5102 may also have a specific shape. For example Figures 1 to 3 shown in the embodiment, the first light-transmitting part 510 includes a flame-shaped light-transmitting hole 5101, two V-shaped strip-shaped light-transmitting grooves 5102, and two V-shaped light-transmitting holes 5101 that are spaced apart from top to bottom on the first cover plate 51. The first light-transmitting part 510 having both the light-transmitting hole 5101 and the strip-shaped light-transmitting groove 5102 can present a more complex and colorful light visual effect, increasing the interest of the lighter protective case. However, in other embodiments, only the light-transmitting hole 5101 or only the strip-shaped light-transmitting groove 5102 may be provided.

[0051] As Figure 5 shown, in some embodiments, the lighter protective case further includes a first backlight plate 61 and a first backlight paper disposed in the third cavity 213. The first backlight plate 61 is disposed corresponding to the first light-emitting unit 3. The first backlight paper covers the first backlight plate 61, and the first backlight paper is disposed between the first backlight plate 61 and the first cover plate 51. Specifically, the first backlight plate 61 and the first backlight paper are disposed on the side of the first light-emitting element 32 away from the first circuit board 31, and the first backlight plate 61 is closer to the first light-emitting element 32 than the first backlight paper. The first backlight plate 61 and the first backlight paper may be fixed to the first housing 21 by their side edges. Alternatively, the first backlight paper may be adhered to the first backlight plate 61. The light source generated on the first light-emitting element 32 can be evenly diffused to the entire first backlight plate 61, and sequentially pass through the first backlight plate 61 and the first backlight paper. The first backlight paper is used to make the light diffusion uniform. The first backlight plate 61 may be a transparent glass, plastic, etc. The first backlight paper may be a light-transmitting diffusing film. The first cover plate 51 is disposed on the side of the first backlight paper away from the first circuit board 31 to cover the third cavity 213.

[0052] As Figure 6As shown, in some embodiments, the first housing 21 further has a fourth cavity 214 which is not in communication with the first cavity 211. Moreover, the fourth cavity 214 and the third cavity 213 are respectively disposed on two opposite sides of the first housing 21. The first light-emitting element 32 is disposed in the third cavity 213. The first light-emitting unit 3 further includes a power supply unit 8. The power supply unit 8 is disposed in the fourth cavity 214 and is connected to the first light-emitting element 32. The connection between the power supply unit 8 and the first light-emitting element 32 can be a wired connection or a wireless connection. Specifically, the power supply unit 8 and the first circuit board 31 can be connected together by welding wires. The fourth cavity 214 is in communication with the third cavity 213 for the wires to pass through. Alternatively, the fourth cavity 214 and the third cavity 213 may not be in communication, and the power supply unit 8 and the first circuit board 31 can be disposed in the same cavity on the first housing 21, or the wires can be wound around the outside of the first housing 21.

[0053] As Figure 7 shown, in some embodiments, the second housing 22 defines a fifth cavity 225 which is not in communication with the second cavity 222. At least a part of the second light-emitting unit 4 is disposed in the fifth cavity 225. The lighter protection case further includes a second cover plate 52. The second cover plate 52 is detachably connected to the second housing 22 and covers the fifth cavity 225. The second cover plate 52 is provided with a second light-transmitting portion 520. The second light-transmitting portion 520 can be set with reference to the first light-transmitting portion 510, and details are not described herein again. Since the second cover plate 52 is detachably connected to the second housing 22, it is convenient to replace different second cover plates 52. Different second cover plates 52 can be provided with second light-transmitting portions 520 of different shapes, presenting different decorative effects and bringing more interesting choices.

[0054] As Figure 7In the illustrated embodiment, the lighter protective case further includes a second backlight plate 71 and a second backlight paper 72 disposed in the fifth cavity 225. The second backlight plate 71 is correspondingly disposed with the second light-emitting unit 4. The second backlight paper 72 covers the second backlight plate 71, and the second backlight paper 72 is disposed between the second backlight plate 71 and the second cover plate 52. Specifically, the second backlight plate 71 and the second backlight paper 72 are disposed on the side of the second light-emitting element 42 away from the second circuit board 41, and the second backlight plate 71 is closer to the second light-emitting element 42 than the second backlight paper 72. The second backlight plate 71 and the second backlight paper 72 can be fixed to the second housing 22 by their side edges. Alternatively, the second backlight paper 72 can be adhered to the second backlight plate 71. The light source generated on the second light-emitting element 42 can be evenly diffused to the entire second backlight plate 71, and sequentially pass through the second backlight plate 71 and the second backlight paper 72. The second backlight paper 72 is used to make the light diffusion uniform. The second backlight plate 71 can be a piece of transparent glass, plastic, etc. The second backlight paper 72 can be a piece of light-transmitting diffuser film. The second cover plate 52 is disposed on the side of the second backlight paper 72 away from the second circuit board 41 to cover the fifth cavity 225.

[0055] Further, as Figure 5 and Figure 6 shown, in some embodiments, the lighter protective case further includes a third cover plate 530. The third cover plate 530 is detachably connected to the first housing 21 and covers the fourth cavity 214. The third cover plate 530 can be used as a physical barrier to protect the components in the fourth cavity 214. Since the third cover plate 530 is detachably connected to the first housing 21, it is convenient to replace the third cover plate 530.

[0056] Further, as Figure 9 shown, in some embodiments, the lighter protective case further includes a fourth cover plate 54. The fourth cover plate 54 is disposed on the opposite side of the second cover plate 52. The fourth cover plate 54 is detachably connected to the second housing 22, which is convenient to replace the fourth cover plate 54.

[0057] Since the first cover plate 51, the second cover plate 52, the third cover plate 530, and the fourth cover plate 54 are detachably connected to the corresponding housings, it is convenient to replace the first cover plate 51, the second cover plate 52, the third cover plate 530, and the fourth cover plate 54.

[0058] As Figure 6As shown, in some embodiments, the power supply unit 8 includes a lithium battery 81, a control chip 82, and a power connection terminal 83. The lithium battery 81 and the control chip 82 are disposed in the fourth cavity 214, and the lithium battery 81 is connected to the control chip 82. A charging port 215 is further formed on the first housing 21, and the charging port 215 communicates with the exterior of the first housing 21 and the fourth cavity 214 respectively. A part of the power connection terminal 83 is located in the fourth cavity 214 and connected to the control chip 82, and another part of the power connection terminal 83 extends out of the fourth cavity 214 and is located in the charging port 215. A connection line of an external power supply is connected to the power connection terminal 83 through the charging port 215, so that the external power supply can be accessed to charge the lithium battery 81. Alternatively, in some other embodiments, the power connection terminal 83 may also be entirely located in the fourth cavity 214.

[0059] The lithium battery 81 is light and small in size, facilitating portability and integration into a small device such as a lighter protection case. Since the lithium battery 81 can be charged by an external power supply, it can provide sufficient power for the first light-emitting element 32 and the second light-emitting element 42. The control chip 82 can adopt a power management integrated circuit (PMIC). Charge and discharge control circuits, overvoltage protection circuits, overcurrent protection circuits, etc. can be designed on the control chip 82. The control chip 82 receives power from the power connection terminal 83 and provides a safe and stable current input for the lithium battery 81, the first light-emitting element 32 on the first circuit board 31, and the second light-emitting element 42 on the second circuit board 41 through the charge and discharge control circuits, overvoltage protection circuits, overcurrent protection circuits, etc.

[0060] As Figure 3 , Figure 5 and Figure 7 In the embodiments shown, the second housing 22 is generally square, and the first housing 21 is also generally square. The number of the first conductive terminals 33 and the second conductive terminals 43 is four each. Four through holes communicating with the fifth cavity 225 are provided on the wall surface of the second housing 22 opposite to the first housing 21. The four second conductive terminals 43 are in contact with the four first conductive terminals 33 through the four through holes on the second housing 22. Four through holes communicating with the third cavity 213 are also provided on the wall surface of the first housing 21 opposite to the second housing 22. The four first conductive terminals 33 partially extend out of the third cavity 213 through the four through holes on the first housing 21 and protrude on the wall surface of the first housing 21 opposite to the second housing 22. When the second housing 22 is in the closed position, the four first conductive terminals 33 are in contact with the four second conductive terminals 43 one by one.

[0061] Specifically, as Figure 8In the illustrated embodiment, the square first housing 21 includes a first front surface 216, a first back surface, and two first side surfaces 217. The first front surface 216 and the first back surface are arranged in parallel at intervals. The two first side surfaces 217 are arranged in parallel at intervals and are respectively connected between the first front surface 216 and the first back surface. The first light-emitting unit is at least partially disposed on the first front surface 216, the first back surface, or the first side surface 217. That is, the first light-emitting unit 3 can be entirely disposed on the first front surface 216, entirely disposed on the first back surface, or entirely disposed on the first side surface 217. During the process of opening and closing the lighter cover, the first front surface 216, the first back surface, or the first side surface 217 of the first housing 21 emits light. Alternatively, the first light-emitting unit 3 can be partially disposed on the first front surface 216, the first back surface, or the first side surface 217. For example, in some embodiments, the first circuit board 31 and all the first light-emitting elements 32 of the first light-emitting unit 3 are disposed on the first front surface 216, while the power supply unit 8 of the first light-emitting unit 3 can be disposed on the first side surface 217 or the first back surface.

[0062] The square second housing 22 includes a second front surface 226, a second back surface, and two second side surfaces 227. The second front surface 226 and the second back surface are arranged in parallel at intervals. The two second side surfaces 227 are arranged in parallel at intervals and are respectively connected between the second front surface 226 and the second back surface. The second light-emitting unit 4 is disposed on the second front surface 226, the second back surface, or the second side surface 227.
