[0029] In the following description, specific details such as specific system structures, techniques, etc. are presented in order to thoroughly understand the embodiments of the present application, but it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits and methods are omitted to avoid unnecessary details that hinder the description of the present application.

[0030] As shown in Figures 1 to 3 The present application constructs a lighter protective shell 1 which can accommodate a lighter 2, prevent the lighter 2 from being scratched, contaminated, etc., and play a protective role. It can also prevent the metal lighter 2 from being too cold in the user's hand in cold weather, improving the user's experience.

[0031] Referring to Figure 9 The lighter protective shell 1 can include a shell 10 and a control assembly 20. The shell 10 includes a first shell 11 and a second shell 12, which define a receiving cavity 13 for receiving the lighter 2. The first shell 11 and the second shell 12 are detachably or rotatably connected, and by disassembling, rotating operation, the opening and closing of the receiving cavity 13 is realized, so that the lighter 2 is placed in the receiving cavity 13, or taken out from the receiving cavity 13.

[0032] The control assembly 20 is arranged on the shell 10 and is used to realize various functions of the lighter protective shell 1. It comprises a main control unit 21, a wireless communication unit 22 and an alarm unit 23. The wireless communication unit 22 and the alarm unit 23 are electrically connected with the main control unit 21 respectively. The wireless communication unit 22 is used to be wirelessly connected with the mobile terminal of the user. The alarm unit 23 is used to send an alarm. The main control unit 21 can be configured to send an alarm information when the wireless communication unit is disconnected with the mobile terminal of the user.

[0033] The first shell 11 and the second shell 12 are arranged to accommodate the lighter 2, so as to protect the lighter 2 from damage due to accidental falling. The control assembly 20 is arranged to realize the effect of anti-lost alarm. The wireless communication unit 22 is arranged to realize the connection with the mobile terminal of the user. The alarm unit 23 and the main control unit 21 are arranged to send an alarm signal when the wireless communication unit 22 is disconnected with the mobile terminal. Whether the mobile terminal of the user is lost or the lighter protective shell 1 and / or the lighter 2 is lost, the user can be timely reminded to reduce the occurrence of the situation.

[0034] As shown in Figure 1 The lighter 2 can comprise a main body 201 and a cover 202. The main body 201 and the cover 202 can be hingedly connected together, so that the cover 202 can be flipped relative to the main body 201 to realize the functions of opening and closing. The main body 201 is mainly used for lighting, and the cover 202 is used to protect the head portion of the main body 201 exposed for lighting and to realize the function of extinguishing by closing.

[0035] In the embodiment shown in Figure 1 The first shell 11 is adapted to the main body 201 of the lighter 2, and the second shell 12 is adapted to the cover 202 of the lighter 2. That is, the first shell 11 and the second shell 12 can be respectively sleeved on the main body 201 and the cover 202 of the lighter 2. In this way, during the flipping of the cover 202 relative to the main body 201, the first shell 11 and the second shell 12 can also be relatively flipped following the opening and closing of the lighter 2.

[0036] It can be understood that the first shell 11 and the second shell 12 can be two independent parts and are detachably connected through a magnetic attraction structure, a buckle structure or the like. Alternatively, the first shell 11 and the second shell 12 can be connected together through a hinge. During the relative rotation of the main body 201 and the cover 202 through the hinge shaft of the lighter 2, the first shell 11 and the second shell 12 can also be relatively rotated relative to their own hinge shafts following the lighter 2.

[0037] The first housing 11 can be interference-fitted with the main unit 201, and the portion of the receiving cavity 13 defined by it can be larger than or equal to the size of the main unit 201. The second housing 12 can be interference-fitted with the cover 202, and the portion of the receiving cavity 13 defined by it can also be larger than or equal to the size of the cover 202. When the first housing 11 and the main unit 201 are interference-fitted, and the second housing 12 and the cover 202 are interference-fitted, the first housing 11 and the second housing 12 can also be two independent parts without a direct connection. By interfering with the main unit 201 and the cover 202 respectively, the lighter 2 is protected by both housings.

[0038] In some other alternative embodiments, the receiving cavity 13 portion defined by the first housing 11 may also only house a portion of the main unit 201, or house the main unit 201 and a portion of the cover 202. Alternatively, the receiving cavity 13 portion defined by the second housing 12 may also only house a portion of the cover 202, or house the cover 202 and a portion of the main unit 201.

[0039] exist Figure 2 and Figure 3 In the illustrated embodiment, the lighter 2 is generally rectangular in shape. Correspondingly, the receiving cavity 13 is also generally rectangular in shape and is adapted to fit the lighter 2. The outer contour of the outer casing 10 is also generally rectangular in shape.

[0040] In some other alternative embodiments, when the lighter 2 is in the shape of a column, a ball, an irregular shape, or other shapes, the shape of the receiving cavity 13 can also be adjusted accordingly. The shape of the outer contour of the receiving cavity 13 and / or the outer contour of the outer shell 10 can also be different from the outer contour of the lighter 2. For example, the lighter 2 is rectangular, the receiving cavity 13 is disc-shaped, and the outer shell 10 is cylindrical, etc.

[0041] In some embodiments, the main control unit 21 may include a first circuit board 211 and a main control module (not shown) disposed on the first circuit board 211.

[0042] In some embodiments, the wireless communication unit 22 can employ existing wireless communication modules such as Bluetooth, Wi-Fi, and LoRa to achieve wireless communication with the mobile terminal. The wireless communication unit 22 can be mounted on the first circuit board 211 and electrically connected to the main control module.

[0043] In some embodiments, the alarm information may be sound information of various alarm sounds, or display information such as emitting lights or displaying reminder characters, or mechanical information such as generating vibrations.

[0044] exist Figure 5In the illustrated embodiment, the alarm unit 23 employs a speaker. When the wireless communication unit 22 is disconnected from the main control unit 21, the alarm unit 23 outputs an alarm sound to promptly remind the user and prevent the loss of the lighter 2 and / or the lighter protective case 1. The alarm unit 23 can also be mounted on the first circuit board 211 and electrically connected to the main control module.

[0045] In some other alternative embodiments, the alarm unit 23 may also employ a motor that generates vibration information, an LED that generates light, a display screen that generates characters, etc.

[0046] In some embodiments, the alarm unit 23 may also be provided with a voice module circuit, which is electrically connected to the main control module to control the normal operation of the speaker. The voice module may be installed on the first circuit board 211 or on a separate circuit board.

[0047] It should be understood that the voice module may include existing circuit modules such as power amplifiers, frequency divider circuits, signal transmission circuits, and filter circuits.

[0048] like Figure 5 As shown, in some embodiments, the first housing 11 may include a first body 111 and a first cover plate 112. The first body 111, together with the second housing 12, may define a receiving cavity 13. A first cavity 115 may also be formed on the first body 111. The first cover plate 112 is detachably disposed on the first body 111 for sealing the first cavity 115.

[0049] The first cavity 115 and the receiving cavity 13 are spaced apart. At least one of the main control unit 21, the wireless communication unit 22, and the alarm unit 23 is disposed within the first cavity 115. The first cover plate 112 seals the first cavity 115, thus protecting the unit modules disposed therein.

[0050] exist Figure 5 In the embodiment shown, the alarm unit 23 is disposed on the first circuit board 211, and the main control unit 21 and the alarm unit 23 are disposed in the first cavity 115.

[0051] In some other alternative embodiments, when the wireless communication unit 22 is also disposed on the first circuit board 211, the wireless communication unit 22 may also be disposed within the first cavity 115.

[0052] like Figure 5 , Figure 8 and Figure 9As shown, in some embodiments, the control assembly 20 can further include a first display unit 24 and a second display unit 25. The first display unit 24 and the second display unit 25 are respectively electrically connected to the control unit 21. The first display unit 24 is arranged on the first shell 11, and the second display unit 25 is arranged on the second shell 12. The second shell 12 can include a first position and a second position during movement relative to the first shell 11. When the second shell 12 is in the first position, the accommodation cavity 13 is open. When the second shell 12 is in the second position, the accommodation cavity 13 is closed.

[0053] It should be understood that when the rotation angle of the second shell 12 relative to the first shell 11 is greater than a first preset value, it can be considered that the second shell 12 is in the first position, and the lighter protective shell 1 is in an open state. When the rotation angle of the second shell 12 relative to the first shell 11 is less than a second preset value, or the first shell 11 and the second shell 12 are mutually buckled, it can be considered that the second shell 12 is in the second position, and the lighter protective shell 1 is in a closed state.

[0054] The first preset value and the second preset value can be the same value or different values. It should be understood that since the rotation angle of the second shell 12 has many choices, the first position and / or the second position can not be unique. The first preset value and the second preset value can be 0°.

[0055] In some embodiments, when the second shell 12 is in the first position, the first display unit 24 is open and the second display unit 25 is closed. When the second shell 12 is in the second position, the first display unit 24 and the second display unit 25 are respectively open for a preset time and then closed.

[0056] It should be understood that the preset time can be flexibly set according to the user's needs, or be a fixed time length. For example, it can be 3 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds, etc.

[0057] By opening and closing the first display unit 24 and the second display unit 25 when the second shell 12 is in different positions, the user can clearly distinguish the opening and closing states of the lighter protective shell 1, and also add interest during the opening and closing of the lighter protective shell 1, and improve the user experience.

[0058] In other some optional embodiments, when the second shell 12 is in the first position, the first display unit 24 and the second display unit 25 can be both open. When the second shell 12 is in the second position, at least one of the first display unit 24 and the second display unit 25 is closed.

[0059] AsFigure 5 As shown, in some embodiments, the first display unit 24 comprises a display control module, at least one first conductive terminal 242 and at least one first light-emitting element 241. The second display unit 25 comprises at least one second conductive terminal 252 and at least one second light-emitting element 251. The control assembly 20 further comprises a triggering device (not shown in the figure), which can be electrically connected with the display control module, for outputting a triggering signal to the display control module.

[0060] Together with Figure 6 The first conductive terminal 242 and the second conductive terminal 252 each comprise two end portions for electrical connection. The first end of the first conductive terminal 242 is electrically connected with the display control module, and the first end of the second conductive terminal 252 is electrically connected with the second light-emitting element 251.

[0061] The display control module is further electrically connected with the master control unit 21, the first light-emitting element 241 and the triggering device, respectively. The display control module can control the first light-emitting element 241 and the second light-emitting element 251 to turn on for a preset time and then turn off upon receiving the triggering signal output by the triggering device.

[0062] When the second shell 12 is in the second position, the second end of the second conductive terminal 252 is electrically connected with the second end of the first conductive terminal 242, the triggering device generates a triggering signal and outputs it to the display control module. Upon receiving the triggering signal, the display control module can control the first light-emitting element 241 and the second light-emitting element 251 to turn on for a preset time and then turn off automatically. When the second shell 12 is in the first position, the second conductive terminal 252 is disconnected from the first conductive terminal 242, and the second light-emitting element 251 is disconnected from the display control module, thus being in an off state. The first light-emitting element 241 is always electrically connected with the display control module, thus being in an on state.

[0063] In some embodiments, the triggering device can comprise a Hall switch and a magnet (not shown in the figure). One of the Hall switch and the magnet is arranged on the first shell 11, and the other is arranged on the second shell 12. The Hall switch and the display control module can be mechanically and / or electrically connected together, and can transmit electrical signals to each other.

[0064] When the second shell 12 is in the first position, the Hall switch and the magnet are far away from each other, and the Hall switch is not affected by the magnetic field, thus being in a non-conductive state. When the second shell 12 is in the second position, the Hall switch and the magnet are close to each other, and the Hall switch is affected by the magnetic field, thus being in a conductive state. The Hall switch generates a triggering signal upon being in the conductive state, and outputs it to the display control module.

[0065] In some other optional embodiments, the trigger device can also be a mechanical switch. It can be arranged on the first shell 11 or the second shell 12 and mechanically and / or electrically connected with the display control module, and the two can transmit electrical signals.

[0066] It should be understood that the mechanical switch is arranged on the first shell 11 or the second shell 12, and the position of the mechanical switch on one of the shells is arranged to be spaced apart from the other shell when the second shell 12 is in the first position. When the second shell 12 is in the second position, the position of the mechanical switch on one of the shells is arranged to be in abutment with the other shell. That is, the mechanical switch can be arranged on the surface of the first shell 11 and the second shell 12 that abut each other when the first shell 11 and the second shell 12 are closed. Therefore, when the second shell 12 is in the first position, the mechanical switch is not conductive. When the second shell 12 is in the second position, the mechanical switch is in abutment with the other shell and is in a conductive state, and outputs a trigger signal.

[0067] It should be understood that the master control module and the display control module can each be a controller such as an MCU, which is not specifically limited here.

[0068] In Figure 5 and Figure 8 In the embodiments shown in FIGS. 1 and 2, the first display unit 24 is arranged on the first shell 11, and the second display unit 25 is arranged on the second shell 12. The electrical connection between the first conductive terminal 242 and the second conductive terminal 252 can be achieved by changing the relative position relationship between the first shell 11 and the second shell 12.

[0069] Referring to FIGS. 1 and 2, Figure 4 and Figure 7 Specifically, it is defined that the first shell 11 includes a first contact surface, and the second shell 12 includes a second contact surface. When the second shell 12 is in the first position, the first contact surface and the second contact surface are arranged to be spaced apart from each other. When the second shell 12 is in the second position, the first contact surface and the second contact surface are arranged to be in abutment with each other.

[0070] The first conductive terminal 242 and the second conductive terminal 252 are respectively arranged on the first shell 11 and the second shell 12, and the second end of the first conductive terminal 242 is exposed on the first contact surface, and the second end of the second conductive terminal 252 is exposed on the second contact surface and is arranged to correspond to the second end of the first conductive terminal 242.

[0071] When the second housing 12 is in the first position, the second end of the first conductive terminal 242 and the second end of the second conductive terminal 252 are distanced from each other due to the first contact surface and the second contact surface being distanced from each other, and the two are not in contact, thus the electrical connection is disconnected. When the second housing 12 is in the second position, the second end of the first conductive terminal 242 and the second end of the second conductive terminal 252 are in contact (even abut) with each other due to the first contact surface and the second contact surface being in contact with each other, and the two are in electrical connection through physical contact. Thus, the first light-emitting element 241, the display control module, the first conductive terminal 242, the second conductive terminal 252, and the second light-emitting element 251 together form a closed circuit, so that the second light-emitting element 251 and the display control module are in electrical connection.

[0072] In Figures 4 to 8 In the embodiment shown, the number of the first conductive terminals 242 and the second conductive terminals 252 is four respectively, and four through holes are also respectively provided on the first housing 11 and the second housing 12, so that the four first conductive terminals 242 and the four second conductive terminals 252 are arranged through the through holes.

[0073] In some embodiments, a delay circuit can be included in the display circuit module, so that the display circuit module can control the first light-emitting element 241 and the second light-emitting element 251 to automatically turn off after a preset time. The trigger device can be used as a trigger switch of the delay circuit.

[0074] It should be understood that the delay circuit can be implemented by using existing technologies, which are not limited here. For example, an RC delay circuit (a combination of resistance and capacitance is used to create a delay. The capacitor is charged through the resistance, and when the voltage reaches a certain level, the first light-emitting element 241 and the second light-emitting element 251 are lit; the delay time can be set by adjusting the values of the resistance and the capacitance), a 555 timer circuit (a multifunctional integrated circuit that can be configured to generate a monostable delay output, thereby controlling the first light-emitting element 241 and the second light-emitting element 251 to light up or turn off after a certain time), a transistor delay circuit (using a transistor and a capacitor to form a Miller integral circuit to achieve delay control; after the capacitor is charged to a certain voltage, the transistor is turned on, and the first light-emitting element 241 and the second light-emitting element 251 are lit), a digital logic circuit (using digital logic gates such as NAND gate, NOR gate, etc. to design delay logic, and different logic combinations are used to control the delay of the first light-emitting element 241 and the second light-emitting element 251), etc.

[0075] As Figure 5As shown, in some embodiments, the first display unit 24 can further include a second circuit board 243, and the first light emitting element 241, the first conductive terminal 242 and the display control module can be disposed on the second circuit board 243 respectively.

[0076] In some embodiments, the second display unit 25 can further include a third circuit board 253, and the second light emitting element 251 and the second conductive terminal 252 can be disposed on the third circuit board 253 respectively.

[0077] In other optional embodiments, when the first display unit 24 and the second display unit 25 do not include circuit boards, the display control module can be disposed on the first circuit board 211, and other components of the first display unit 24 and / or the second display unit 25 can be directly disposed on the housing 10 or partially disposed on the first circuit board 211 and partially directly disposed on the housing 10.

[0078] In other optional embodiments, the wireless communication unit 22 and / or the alarm unit 23 can be disposed on the second circuit board 243 or the third circuit board 253.

[0082] ​At least a portion of the first display unit 24 is disposed within the second cavity 116, and at least a portion of the second display unit 25 is disposed within the third cavity 124. This arrangement facilitates the switching of power between the first conductive terminal 242 and the second conductive terminal 252 by rotating the second housing 12 between the first and second positions.

[0083] exist Figure 5 In the illustrated embodiment, the first light-emitting element 241, the second circuit board 243, the display control module disposed on the second circuit board, and a portion of each first conductive terminal 242 are all disposed within the second cavity 116. The remaining portion of each first conductive terminal 242 passes through the first main body 111 and is partially exposed on the first contact surface. The second light-emitting element 251, the third circuit board 253, and a portion of each second conductive terminal 252 are all disposed within the third cavity 124. The remaining portion of each second conductive terminal 252 passes through the second main body 121 and may be partially exposed on the second contact surface.

[0084] In some other alternative embodiments, the first display unit 24 may also be disposed on the second housing 12, and the second display unit 25 may be disposed on the first housing 11.

[0085] In some other alternative embodiments, some of the first display units 24 may also be disposed at other locations outside the second cavity 116 of the first housing 11 (for example, some of the first light-emitting elements 241 may be disposed inside the first cavity 115), and / or some of the second display units 25 may also be disposed at other locations outside the third cavity 124 of the second housing 12.

[0086] It should be understood that, in order to output the light emitted by the first light-emitting element 241 and the second light-emitting element 251 to the user, at least a portion of the second cover plate 113 and at least a portion of the third cover plate 122 are light-transmitting plates.

[0087] The light emitted by the first light-emitting element 241 can be dispersed through the light-transmitting portion of the second cover plate 113, and the light emitted by the second light-emitting element 251 can be dispersed through the light-transmitting portion of the third cover plate 122, with the remainder blocked by the non-transparent portion. Therefore, from the user's perspective, the light emitted by the light-transmitting portions of the second cover plate 113 and the third cover plate 122 can be seen, which has a decorative effect, further increasing the fun of the lighter protective case 1 and improving the user experience.

[0088] Meanwhile, since the second cover plate 113 is detachably connected with the first body 111 and / or the third cover plate 122 is detachably connected with the second body 121 in some embodiments, different second cover plates 113 and / or third cover plates 122 can be replaced, and the light-transmitting part thereof is set to different shapes, so as to further increase the appearance decoration effect and improve the use experience.

[0089] In other optional embodiments, when part of the first light-emitting element 241 or part of the second light-emitting element 251 is arranged at other positions outside the second cavity 116 and the third cavity 124, the cover plate at the corresponding position can also be at least partially set as a light-transmitting plate.

[0090] In some embodiments, the first light-emitting element 241 can be an LED lamp or a light-emitting diode, and is installed on the second circuit board 243. The second light-emitting element 251 can be an LED lamp or a light-emitting diode, and is installed on the third circuit board 253. The number of the first light-emitting element 241 and / or the second light-emitting element 251 can be set as one or more, and can have two or more colors, so as to further increase the appearance effect and improve the use experience of the user.

[0091] In some embodiments, the light-transmitting part of the second cover plate 113 can be set as a dot shape and / or a longitudinal strip shape. The number thereof can be set as one or more according to the number of the first light-emitting element 241, and is arranged at different positions on the surface of the second cover plate 113 to form different shapes, so as to present a more complex and colorful light visual effect and increase the interest of the lighter protective shell. The light-transmitting part on the third cover plate 122 is the same, and will not be described here.

[0092] It should be understood that when the light-transmitting part is a small hole or a strip, it can be set as a through hole in the thickness direction of the cover plate, so that the light emitted by the light-emitting element transmits through the through hole.

[0093] In other optional embodiments, the light-transmitting part can also be made of a light-transmitting material such as glass to achieve the light-transmitting effect.

[0094] Continuing to refer to Figure 5In some embodiments, the first display unit 24 further includes a first backlight paper 244 and a first backlight panel 245. The first backlight panel 245 is correspondingly disposed to the first light-emitting element 241. The first backlight paper 244 covers the first backlight panel 245 and is disposed on the side of the first backlight panel 245 facing away from the first light-emitting element 241, for uniform light diffusion. That is, the first backlight paper 244 is located between the first backlight panel 245 and the second cover plate 113. The light source generated on the first light-emitting element 241 can be uniformly diffused to the entire first backlight panel 245, and sequentially passes through the first backlight panel 245 and the first backlight paper 244, before being emitted through the light-transmitting portion of the second cover plate 113.

[0095] like Figure 8 As shown, in some embodiments, the second display unit 25 further includes a second backlight paper 254 and a second backlight plate 255. The second backlight plate 255 is correspondingly disposed to the second light-emitting element 251. The second backlight paper 254 covers the second backlight plate 255 and is disposed on the side of the second backlight plate 255 facing away from the second light-emitting element 251, for uniform light diffusion. That is, the second backlight paper 254 is located between the second backlight plate 255 and the third cover plate 122. The light emitted from the second light-emitting element 251 can be uniformly diffused throughout the second backlight plate 255, and sequentially passes through the second backlight plate 255 and the second backlight paper 254, before being emitted through the light-transmitting portion of the third cover plate 122.

[0096] It should be understood that the first backlight panel 245 and the first backlight paper 244 can be fixed to the first main body 111 via their sides, thus achieving fixation within the second cavity 116. Similarly, the second backlight panel 255 and the second backlight paper 254 can be fixed to the second main body 121 via their sides, thus achieving fixation within the third cavity 124. The first backlight panel 245 and the second backlight panel 255 can be made of transparent glass, plastic, or the like. The first backlight paper 244 and the second backlight paper 254 can be made of light-transmitting diffusing film.

[0097] In some alternative embodiments, the first display unit 24 may omit the first backlight paper 244 and the first backlight panel 245, and the first light-emitting element 241 may be configured as a display screen. This display screen can display a logo or related animation, or be customized or selected according to user needs. In this case, the light-transmitting portion of the second cover plate 113 can be configured as a block shape corresponding to the display screen to output the content displayed on the screen. Such a configuration can further enhance the appeal of the lighter protective case 1 and improve the user experience.

[0098] In some other optional embodiments, the second display unit 25 can also not be provided with the second back light paper 254 and the second back light plate 255, and the second light emitting element 251 can be provided as a display screen. When the first light emitting element 241 and the second light emitting element 251 are both display screens, they can display the same picture, or can display different pictures respectively (for example, one displays a LOGO mark, and the other displays a customized animation, etc.). One can be provided as a display screen, and the other can be provided as an LED or a light emitting diode.

[0099] As shown in Figure 5 and Figure 9 In some embodiments, the control assembly 20 further includes a power supply unit 27 electrically connected with the main control unit 21, for providing power supply for the operation of the control assembly 20.

[0100] The first shell 11 can further include a fourth cover plate 114, and the first body 111 can further be formed with a fourth cavity (not shown in the figure) in which at least part of the power supply unit 27 is arranged. The fourth cavity is spaced apart from the receiving cavity 13, the first cavity 115 and the second cavity 116 respectively. The fourth cover plate 114 is detachably arranged on the first body 111 to cover the fourth cavity, thereby protecting the power supply unit 27 to a certain extent.

[0101] It should be understood that the power supply unit 27 can include a battery 271 and a power supply module circuit, the battery 271 is electrically connected with the power supply module, and the power supply module is electrically connected with the main control module of the main control unit 21. The power supply unit 27 can be provided with a circuit board to arrange the power supply module. The circuit board can be arranged in the fourth cavity together with the battery, or one of the circuit board and the battery 271 can be arranged in the fourth cavity, and the other one can be arranged in the first cavity 115 or the second cavity 116.

[0102] In some other optional embodiments, the power supply module circuit of the power supply unit 27 can also be arranged on the first circuit board 211 or the second circuit board 243.

[0103] As shown in Figure 5 In some embodiments, the power supply unit 27 can further include a wiring terminal 272, one end of which is electrically connected with the power supply module, and the other end is used to connect an external power supply to charge the battery 271. The first shell 11 can further be provided with a charging port 1121 corresponding to the position of the wiring terminal 272, and the wiring terminal 272 is arranged at the charging port 1121 to connect the external power supply.

[0104] In Figure 5In the shown embodiment, the charging port 1121 is arranged on the first cover plate 112, and connects the first cavity 115 with the outside. The terminal 272 is arranged in the first cavity 115, and is fixed on the first circuit board 211.

[0105] In some alternative embodiments, the terminal 272 can also be arranged on the second circuit board 243 or the third circuit board 253 or the circuit board of the power supply unit 27, and the charging port 1121 can also be arranged on the second cover plate 113, the third cover plate 122, the fourth cover plate 114 or other positions.

[0106] It should be understood that the battery 271 can be a lithium battery, which is light, small in size, and convenient to carry and integrate into the lighter protective shell 1. The power supply module can also directly use a power management integrated circuit (PMIC), which can be designed with a charge and discharge control circuit, an overvoltage protection circuit, an overcurrent protection circuit, etc., to provide stable voltage input.

[0107] In some embodiments, the first cavity 115, the second cavity 116 and the fourth cavity are respectively located on the circumference of the receiving cavity 13 defined by the first shell 11. The fourth cavity and the first cavity 115 can be respectively located on opposite sides of the receiving cavity 13 defined by the first shell 11. The first cavity 115 is located between the second cavity 116 and the fourth cavity to achieve mutual spacing of the four cavities.

[0108] Arranging the cavities on the circumference of the receiving cavity 13 can thicken the relative thickness of the side wall of the receiving cavity 13, further improving the protection effect of the lighter 2 in the receiving cavity 13. At the same time, the three cavities are respectively located on the circumference of the receiving cavity 13, which can also uniformly thicken the side wall thickness of each position on the circumference of the receiving cavity 13, improve the space utilization rate, and reduce the volume of the lighter protective shell 1.

[0109] In Figures 1 to 8 In the shown embodiment, since physical contact between the first conductive terminal 242 and the second conductive terminal 252 needs to be achieved, the second cavity 116 and the third cavity 124 need to be located on the same side of the receiving cavity 13. Therefore, the arrangement position of the third cavity 124 on the second shell 12 is adjusted flexibly according to the arrangement position of the second cavity 116 on the first shell 11.

[0110] In Figure 2 and Figure 3In the illustrated embodiment, the hinge shaft between the first shell 11 and the second shell 12 is disposed at the second side 104 of the first shell 11 and the second shell 12. Referring to FIG. 1 and FIG. 2, the hinge shaft is disposed at the second side 104 of the first shell 11 and the second shell 12.

[0111] In the illustrated embodiment, the first shell 11 and the second shell 12 are connected by a hinge shaft disposed at the second side 104 of the first shell 11 and the second shell 12. Referring to FIG. 1 and FIG. 2, the hinge shaft is disposed at the second side 104 of the first shell 11 and the second shell 12. Figure 3 In the illustrated embodiment, the hinge shaft between the first shell 11 and the second shell 12 is disposed at the second side 104 of the first shell 11 and the second shell 12. Referring to FIG. 1 and FIG. 2, the hinge shaft is disposed at the second side 104 of the first shell 11 and the second shell 12. Figure 5 In the illustrated embodiment, the hinge shaft between the first shell 11 and the second shell 12 is disposed at the second side 104 of the first shell 11 and the second shell 12. Referring to FIG. 1 and FIG. 2, the hinge shaft is disposed at the second side 104 of the first shell 11 and the second shell 12. Figure 8 In the illustrated embodiment, the hinge shaft between the first shell 11 and the second shell 12 is disposed at the second side 104 of the first shell 11 and the second shell 12. Referring to FIG. 1 and FIG. 2, the hinge shaft is disposed at the second side 104 of the first shell 11 and the second shell 12.

[0112] In other alternative embodiments, the first cavity 115 and the fourth cavity 117 can be disposed at two adjacent side walls of the first shell 11, for example, at the front side 101 and the first side 103, respectively, and the first cavity 115 and the second cavity 116 are disposed at opposite sides. Or one of the first cavity 115, the second cavity 116, and the fourth cavity 117 is disposed at the bottom side 106 of the first shell 11, and the other two are disposed at opposite or adjacent sides of the first shell 11.

[0113] In other alternative embodiments, the third cavity 124 can be disposed at different sides from the second cavity 116. For example, when the second cavity 116 is disposed at the first side 103 of the first shell 11, the third cavity 124 can be disposed at the back side 102, the first side 103, the second side 104, or the top side 105 of the second shell 12. In this embodiment, the electrical connection between the first conductive terminal 242 and the second conductive terminal 252 can also be achieved by non-physical contact. For example, by connecting a cable and setting a sensor switch, the sensor switch is triggered when the second shell 12 is rotated to a predetermined angle.

[0114] As shown in FIG. 1 and FIG. 2, the first conductive terminal 242 is disposed at the first side 103 of the first shell 11, and the second conductive terminal 252 is disposed at the second side 104 of the second shell 12. Figure 8As shown, in some embodiments, the second shell 12 can further include a fifth cover plate 123, and a fifth cavity (not shown) can be further formed on the second body 121. The fifth cavity is spaced apart from the receiving cavity 13 and the third cavity 124 respectively. The fifth cover plate 123 is detachably arranged on the second body 121 to cover the fifth cavity.

[0115] In Figure 8 In the embodiment as shown, the fifth cavity is a hollow cavity and is located at the back side 102 of the second shell 12 to correspond to the fourth cavity, so as to realize the smoothness of the inner wall of the receiving cavity 13 and ensure the smoothness of the outer wall of the shell 10. That is, the consistency of the wall thickness at the corresponding positions of the first shell 11 and the second shell 12 is realized.

[0116] In other optional embodiments, at least part of the components in the control assembly 20 can also be arranged in the fifth cavity.

[0117] In some embodiments, a plurality of rib plates can be arranged in the first cavity 115, and / or the second cavity 116, and / or the third cavity 124, and / or the fourth cavity, and / or the fifth cavity, so as to support the cavities and improve the strength of the shell 10.

[0118] In Figure 5 In the embodiment as shown, the second cover plate 113, the third cover plate 122, the fourth cover plate 114 and the fifth cover plate 123 are substantially rectangular plates. The second cover plate 113 and the fourth cover plate 114 are respectively located at the front side 101 and the back side 102 of the first shell 11. The third cover plate 122 and the fifth cover plate 123 are respectively located at the front side 101 and the back side 102 of the second shell 12. The first cover plate 112 is substantially formed by connecting three rectangular plates end to end, and its cross section is substantially in the shape of a concave letter. Meanwhile, the first cover plate 112 covers the first side 103, the second side 104 and the bottom side 106 of the first shell 11.

[0119] In other optional embodiments, the second shell 12 can further include a sixth cover plate 125 which is detachably arranged on the second body 121 and surrounds the first side 103, the second side 104 and the top side 105 of the second body 121 to correspond to the first cover plate 112.

[0120] In other optional embodiments, when the first shell 11 and the second shell 12 are in the shape of a cylinder, a polygonal column or other shapes, the cover plate can also be in the shape of an arc plate, a cylindrical plate or the like, or at least two cover plates can be combined into one cover plate.

[0121] As Figure 5As shown, in some embodiments, a through hole 1122 may be formed at the position corresponding to the bottom surface 106 of the first cover plate 112, connecting the receiving cavity 13 to the outside. The size of the through hole 1122 is smaller than the size of the lighter 2 to prevent the lighter 2 from falling out. By providing the receiving cavity 13, when the size of the receiving cavity 13 is adapted to the lighter 2, the pressure difference inside and outside the receiving cavity 13 can be kept stable during the process of taking out and putting in the lighter 2, which facilitates the smooth process of taking out and putting in the lighter 2.

[0122] like Figures 1 to 5 As shown, in some embodiments, the control component 20 may further include an adjustment switch 26. See also... Figure 9 The adjustment switch 26 is electrically connected to the main control unit 21 and is used to allow the user to output control information to the control component 20 and select the corresponding mode.

[0123] For example, the main control module or display control module may store display information (such as different animation types, different light colors, different light combinations, etc.) of at least two first display units 24 and / or second display units 25, and the adjustment switch 26 may adjust the display information output by the first display unit 24 and / or second display unit 25.

[0124] For example, when the alarm unit 23 is a speaker, it can also be used to output voice information. In this embodiment, the adjustment switch 26 can adjust the on / off state of the voice mode of the alarm unit 23. For example, when the voice mode is off, the alarm unit 23 only performs the alarm function. When the voice mode is on, and the second housing 12 is in the first position (receiving cavity 13 is open), the alarm unit 23 outputs voice information. For example, when the voice mode is on, and the second housing 12 changes to the second position (receiving cavity 13 is closed), the alarm unit 23 outputs voice information for a preset time and then turns off. For example, when the voice mode is on, and the second housing 12 changes to the first position (receiving cavity 13 is open), the alarm unit 23 outputs voice information for a preset time and then turns off. There are many possible embodiments, and no specific limitation is made here.

[0125] exist Figures 1 to 4 In the embodiment shown, the adjustment switch 26 is a rotary switch, which is rotatably disposed on the first circuit board 211, at least partially located inside the first cavity 115, and partially exposed outside the housing 10, so as to control the switching of the mode or adjust the output intensity of the mode by rotating the knob.

[0126] See also Figure 5The adjustment switch 26 is arranged at the joint of the front face 101 and the first side face 103 of the first shell 11, and therefore the first main body 111, the first cover plate 112 and the second cover plate 113 are correspondingly formed with accommodation grooves to accommodate the adjustment switch 26, thereby improving the smoothness of the outer contour of the shell 10.

[0127] In other optional embodiments, the adjustment switch 26 can also be arranged on the second circuit board 243 or the third circuit board 253 or other circuit boards, or a separate circuit board can be arranged to install the adjustment switch 26. Correspondingly, the arrangement position on the shell 10 can also be at the second cavity 116, the fourth cavity, the third cavity 124, the fifth cavity, etc.

[0128] In other optional embodiments, the number of adjustment switches 26 can be two or more, one of which adjusts the display information of the first display unit 24 and / or the second display unit 25, and the other adjusts the switch of the voice mode, or one adjustment switch 26 can be arranged to adjust the content output by the voice mode.

[0129] In other optional embodiments, the adjustment switch 26 can also adopt other existing switch forms such as a sliding switch, a toggle switch, a key switch, a code switch, a touch switch, etc.

[0130] In some embodiments, the end face of the first shell 11 and the second shell 12 in contact with each other can also be provided with a magnet or a buckle structure. Through the magnetic attraction or buckle connection between the two, the stability of the closed state of the two in the second position can be realized, and the automatic opening of the shell 10 to cause the lighter 2 to fall is avoided.

[0131] In some embodiments, the first shell 11 and / or the second shell 12 can be made of metal, plastic, glass, leather, etc. Further, the cover plates in the first shell 11 and / or the second shell 12 can also be replaced with different materials or surface treatment processes to give users different use experiences.

[0132] As shown in Figure 1 The present application also constructs a lighter device, which comprises a lighter 2 and the lighter protective shell 1 in any of the foregoing embodiments. The lighter 2 is detachably arranged in the accommodation cavity 13 of the lighter protective shell 1.

[0133] It can be understood that the above embodiments only express part of the embodiments of the present application, the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application; it should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, the above-mentioned embodiments or technical features can be freely combined, and some modifications and improvements can be made, which belong to the protection scope of the present application, that is, the embodiments described in "in some embodiments" can be freely combined with any embodiment above and below; therefore, any equivalent transformation and modification made with the scope of the claims of the present application shall belong to the scope of the claims of the present application.
