Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0017] In the description of this application, it should be understood that the terms "longitudinal", "lateral", "up", "down", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings or the orientation or positional relationship commonly used when the product of this application is in use.

Therefore, they should not be construed as limitations on this application.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0021] Figures 1 to 8 The illustration shows a lighter protective case 1 in one embodiment of this application, which can accommodate a lighter 2 to prevent the lighter 2 from being scratched, contaminated, etc., and to protect the lighter 2.

[0022] The lighter protective case 1 may include a first housing 10, a second housing 20, a control component 30, a display component 40, and a power supply component. The first housing 10 and the second housing 20 are rotatably or detachably connected, together defining a receiving cavity 60 for housing the lighter 2. The user can open or close the receiving cavity 60 by rotating or removing the first housing 10 and the second housing 20, thereby placing the lighter 2 inside or removing it from the receiving cavity 60.

[0023] The control component 30 is disposed within the first housing 10 and / or the second housing 20, and is used to control the normal operation of various functions of the lighter protective case 1. The display component 40 and the power supply component are electrically connected to the control component 30, and the display screen 41 is used to display images under the control of the control component 30. The power supply component is used to provide electrical energy for the operation of the lighter protective case 1.

[0024] By setting the first housing 10 and the second housing 20, the lighter 2 can be completely enclosed and contained, which can protect the lighter 2 from being scratched and prevent the lighter 2 from being damaged due to accidental drop.

[0025] By setting up the display component 40, the fun and aesthetics of the lighter protective case 1 can be improved, thereby enhancing the user experience.

[0026] like Figure 1 As shown, the lighter 2 may include a main body 201 and a cover 202. The main body 201 and the cover 202 are hinged together so that the cover 202 can be flipped relative to the main body 201 to achieve the functions of opening and closing the cover. The main body 201 is mainly used for ignition, and the cover 202 is used to protect the exposed ignition head of the main body 201 and to extinguish the flame by closing the cover.

[0027] See also Figure 3 The receiving cavity 60 defined by the first housing 10 is adapted to the main body 201 of the lighter 2, and the receiving cavity 60 defined by the second housing 20 is adapted to the cover 202 of the lighter 2. That is, the first housing 10 and the second housing 20 can be respectively fitted onto the main body 201 and the cover 202 of the lighter 2. Thus, during the process of the cover 202 flipping relative to the main body 201, the first housing 10 and the second housing 20 can also flip relative to each other as the lighter 2 opens and closes.

[0028] It is understood that the first housing 10 and the second housing 20 can be two independent parts, detachably connected by a magnetic or snap-fit ​​connection structure. Alternatively, they can be connected by a hinge, so that as the main unit 201 and the cover 202 rotate relative to each other via the hinge axis of the lighter 2, the first housing 10 and the second housing 20 can also rotate relative to each other along with the lighter 2 and relative to their own hinge axes.

[0029] The first housing 10 and the main unit 201 can be interference-fitted, and the receiving cavity 60 defined by the first housing 10 can be larger than or equal to the size of the main unit 201. The second housing 20 and the cover 202 can also be interference-fitted, and the receiving cavity 60 defined by the second housing 202 can be larger than or equal to the size of the cover 202. When the first housing 10 and the main unit 201 are interference-fitted, and the second housing 20 and the cover 202 are also interference-fitted, the first housing 10 and the second housing 20 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.

[0030] In some other alternative embodiments, the receiving cavity 60 defined by the first housing 10 may also contain only a portion of the main unit 201, or contain the main unit 201 and a portion of the cover 202. Alternatively, the receiving cavity 60 defined by the second housing 20 may also contain only a portion of the cover 202, or contain the cover 202 and a portion of the main unit 201.

[0031] exist Figure 1 In the illustrated embodiment, the lighter 2 is generally rectangular in shape. Correspondingly, the receiving cavity 60 is also generally rectangular in shape and is adapted to fit the lighter 2. The outer contour of the lighter protective case 1 is also generally rectangular in shape.

[0032] In other optional embodiments, when the lighter 2 is cylindrical, polygonal cylindrical, spherical, cylindrical, hemispherical, disc-shaped, irregular, or other shapes, the shape of the receiving cavity 60 can also be adjusted accordingly. The shape of the receiving cavity 60 and / or the outer contour of the lighter protective shell 1 can also be different from the outer contour shape of the lighter 2. For example, the lighter 2 is rectangular, the receiving cavity 60 is disc-shaped, and the outer contour of the lighter protective shell 1 is cylindrical, etc.

[0033] In some other embodiments, the lighter protective case 1 may include only the first housing 10, or only the second housing 20.

[0034] like Figures 2 to 4 , Figure 7 and Figure 8 As shown, in some embodiments, the first housing 10 may include a first inner housing 11, a first outer housing 12, and a first irregularly shaped housing 13. The first inner housing 11 defines a partial receiving cavity 60 for accommodating the lighter 2. The first outer housing 12 is fitted over the first inner housing 11 and, together with the first inner housing 11, defines a mounting cavity 100. The first irregularly shaped housing 13 is disposed outside the first outer housing 12 to create a decorative effect, thereby enhancing the aesthetics of the lighter protective case 1 and the user's enjoyment, thus improving the user experience. A portion of the first outer housing 12 is exposed and not obscured by the first irregularly shaped housing 13.

[0035] The direction in which the first housing 10 and the second housing 20 of the lighter protective case 1 are aligned is defined as the first direction X. The lighter protective case 1 may also have a second direction Y and a third direction Z. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. For example, in... Figure 2 and Figure 3 In the embodiment shown, the first direction X is the height direction of the lighter protective shell 1, the second direction Y is the width direction of the lighter protective shell 1, and the third direction Z is the thickness direction of the lighter protective shell 1.

[0036] Both the first inner shell 11 and the first outer shell 12 are shells with one open end. When the first shell 10 and the second shell 20 are closed together, the open end of the first inner shell 11 mates with the open end of the second shell 20 to form a relatively closed receiving cavity 60 for covering the lighter 2. The first outer shell 12 extends through one end near the second shell 20 along the first direction X to fit the first inner shell 11 and facilitates docking with the second shell 20. The mounting cavity 100 is located radially between the first outer shell 12 and the first inner shell 11. The first irregular shell 13 extends through both ends along the first direction X and is located on the outer periphery of the first outer shell 12 in a plane perpendicular to the first direction X.

[0037] It should be noted that the mounting cavity 100 can be used to accommodate the display component 40, and / or the power supply component, and / or at least part of the control component 30. The empty portion of the mounting cavity 100 may also be provided with at least one protruding rib, rib or other structure to support it between the first inner shell 11 and the first outer shell 12, so as to improve the structural strength of the first shell 10.

[0038] It should be noted that the first inner shell 11 and the first outer shell 12 can be made of various plastic materials, while the first irregularly shaped shell 13 can be made of metal or alloy materials. In this way, the first irregularly shaped shell 13 can ensure the user's grip feel, and the plastic first inner shell 11 and the first outer shell 12 can also prevent the lighter protective case 1 from being too heavy, making it easier for the user to carry and reducing costs.

[0039] By defining an installation cavity 100 between the first inner shell 11 and the first outer shell 12, other components can be accommodated, and the weight of the first shell 10 can be reduced, providing users with a lighter and more comfortable user experience.

[0040] Meanwhile, due to the properties of plastic, thicker plastic shells are prone to shrinkage and deformation during injection molding. By setting the first inner shell 11 and the first outer shell 12 to be nested together, the thickness of a single shell structure can be effectively reduced, avoiding shrinkage and deformation problems during injection molding.

[0041] It should be noted that the assembly between the first housing 10 and the first outer shell 12, and between the first outer shell 12 and the first irregular shell 13, can be detachably or non-detachably assembled through snap-fit ​​connection, bolt connection, threaded connection, interference fit, integral molding, glue connection, etc., and no specific limitation is made here.

[0042] In some other embodiments, the first housing 10 may also include only a first inner housing 11 and a first outer housing 12.

[0043] In other embodiments, the first outer shell 12 may also be composed of at least two plate-like structures that cover the first inner shell 11 and together with the first inner shell 11 define at least two mutually separated cavities. All cavities together constitute the mounting cavity 100.

[0044] In some other embodiments, the first irregular shell 13 may also be plate-shaped and only cover part of the side surface of the first outer shell 12.

[0045] It should be noted that the specific shape of the first irregular shell 13 can be set to a specific logo, or it can be flexibly set according to the user's needs, and no specific limitation is made here.

[0046] In some other embodiments, the lighter protective case 1 may also have multiple first irregular shells 13 of different shapes. Users can flexibly choose to assemble different shaped first irregular shells 13 on the first outer shell 12 according to their own preferences, so as to further enhance the fun of the lighter protective case 1 and increase the user's user experience.

[0047] In some other alternative embodiments, the first irregularly shaped shell 13 can also be integrally formed with the first outer shell 12 into a single structure. That is, when the first shell 10 only includes the first inner shell 11 and the first outer shell 12, an irregularly shaped protrusion structure can be provided on the first outer shell 12 to achieve a decorative effect.

[0048] like Figure 3 and Figure 4 As shown, in some embodiments, the first housing 10 also defines at least one through hole 14, which communicates with the receiving cavity 60 and the outside. The size of the through hole 14 may be smaller than the size of the lighter 2 to prevent the lighter 2 from falling out.

[0049] By providing through hole 14, when the size of receiving cavity 60 is adapted to lighter 2, the pressure difference inside and outside receiving cavity 60 can be kept stable during the process of taking and putting away lighter 2, which facilitates the smooth process of taking and putting away lighter 2.

[0050] Specifically, the through hole 14 is located at the end of the first housing 10 away from the second housing 20 along the first direction X. When the first housing 10 includes a first inner housing 11 and a first outer housing 12, both the first inner housing 11 and the first outer housing 12 are provided with corresponding connecting holes, which are connected to each other to form the through hole 14.

[0051] like Figure 7 and Figure 8As shown, in some embodiments, at least a portion of the display component 40, the power supply component, and the control component 30 are all disposed on the first housing 10. The display component 40 and the power supply component are disposed on opposite sides of the first inner housing 11 along a direction perpendicular to the first direction X. At least a portion of the control component 30 is disposed circumferentially between the display component 40 and the power supply component of the first inner housing 11.

[0052] See also Figure 5 The mounting cavity 100 is now defined as consisting of four sequentially connected cavities: a first cavity 101, a second cavity 102, a third cavity 103, and a fourth cavity 104. The first cavity 101 and the second cavity 102 are positioned opposite each other along the second direction Y. The third cavity 103 and the fourth cavity 104 are located between the first cavity 101 and the second cavity 102, and are positioned opposite each other along the third direction Z.

[0053] At least a portion of the control components 30 are disposed in the first cavity 101, at least a portion of the display components 40 are disposed in the third cavity 103, and at least a portion of the power supply components are disposed in the fourth cavity 104. When the first housing 10 and the second housing 20 are rotatably connected, the pivot shaft connecting them is disposed on the side of the first housing 10 and the second housing 20 corresponding to the second cavity 102.

[0054] In some other embodiments, at least two of the display component 40, the power supply component, and the control component 30 may also be disposed in one of the cavities.

[0055] In some other embodiments, the pivot shaft that rotatably connects the first housing 10 and the second housing 20 may also be located on the side corresponding to the first cavity 101, the third cavity 103, or the fourth cavity 104.

[0056] In some other embodiments, the display component 40, and / or the power supply component, and / or the control component 30 may also be at least partially disposed in the second housing 20.

[0057] like Figure 5 As shown, in some embodiments, the first irregularly shaped shell 13 is provided with a display window 131, and the first outer shell 12 is correspondingly provided with a first clearance opening 123. The first clearance opening 123 communicates with both the display window 131 and the mounting cavity 100, and the display window 131 communicates with the outside. (See also...) Figure 7 and Figure 8 The display screen 41 of the display component 40 is disposed within the mounting cavity 100 and displays information through the first clearance opening 123 and the display window 131. The first housing 10 also includes a transparent cover plate 15, which covers the display window 131 to ensure that the display component 40 is protected from damage while displaying information.

[0058] It should be noted that the transparency of the cover plate 15 can be either a fully transparent plate structure or a semi-transparent plate structure. The level of transparency can be flexibly adjusted to match the display effect required by the display screen 41 of the display component 40, and no specific limitation is made here.

[0059] The specific shapes of the cover plate 15, the display window 131, and the first clearance opening 123 can be set according to the shape of the display screen 41 of the display component 40, and are not specifically limited here.

[0060] It should be noted that the assembly of the cover plate 15 and the first irregular shell 13 can be achieved through snap-fit ​​connection, interference fit, abutment limit, integral molding, etc., and no specific limitation is made here.

[0061] In some other embodiments, when the first irregular shell 13 does not cover the position corresponding to the display screen 41 of the first outer shell 12 and the display component 40, or when the first outer shell 10 is not provided with the first irregular shell 13, the cover plate 15 may also cover the first clearance opening 123.

[0062] In some other embodiments, when the display screen 41 of the display component 40 is disposed on the second housing 20, the display window 131 may be disposed on the second irregular housing 23, and the first clearance opening 123 may be disposed on the second outer housing 22.

[0063] For example Figures 2 to 4 , Figure 7 and Figure 8 As shown, in some embodiments, the second housing 20 may include a second inner housing 21, a second outer housing 22, and a second irregularly shaped shell 23. The second inner housing 21 defines a partial receiving cavity 60 for accommodating the lighter 2. The second outer housing 22 is fitted over the second inner housing 21 and, together with the second inner housing 21, defines a cavity 200. The second irregularly shaped shell 23 is disposed outside the second outer housing 22 to create a decorative effect, thereby enhancing the aesthetics of the lighter protective case 1 and the user's enjoyment, thus improving the user experience. A portion of the second outer housing 22 is exposed and not obscured by the second irregularly shaped shell 23.

[0064] Specifically, both the second inner shell 21 and the second outer shell 22 are shells with one open end. When the first shell 10 and the second shell 20 are closed together, the open end of the second inner shell 21 mates with the open end of the first shell 10, forming a relatively closed receiving cavity 60 for covering the lighter 2. The second outer shell 22 extends through one end near the first shell 10 along the first direction X to fit over the second inner shell 21 and facilitates docking with the first shell 10. The cavity 200 is located radially between the second outer shell 22 and the second inner shell 21. The second irregular shell 23 extends through both ends along the first direction X and is located on the outer periphery of the second outer shell 22 in a plane perpendicular to the first direction X.

[0065] It should be noted that the cavity 200 can be used to house the display component 40, and / or the power supply component, and / or at least part of the control component 30. The empty portion of the cavity 200 may also be provided with at least one protruding rib, rib or other structure to support the second inner shell 21 and the second outer shell 22, so as to improve the structural strength of the second shell 20.

[0066] It should be noted that the second inner shell 21 and the second outer shell 22 can be made of various plastic materials, while the second irregular shell 23 can be made of metal or alloy materials. In this way, the second irregular shell 23 can ensure the user's grip feel, and the plastic second inner shell 21 and the second outer shell 22 can also prevent the lighter protective case 1 from being too heavy, making it easier for the user to carry and reducing costs.

[0067] By defining a cavity 200 between the second inner shell 21 and the second outer shell 22, other components can be accommodated, and the weight of the second shell 20 can be reduced, providing users with a lighter and more comfortable user experience.

[0068] Meanwhile, due to the properties of plastic, thicker plastic shells are prone to shrinkage and deformation during injection molding. By setting the second inner shell 21 and the second outer shell 22 to be nested together, the thickness of a single shell structure can be effectively reduced, avoiding shrinkage and deformation problems during injection molding.

[0069] It should be noted that the assembly between the second inner shell 21 and the second outer shell 22, and between the second outer shell 22 and the second irregular shell 23, can be detachably or non-detachably assembled through snap-fit ​​connection, bolt connection, threaded connection, interference fit, integral molding, glue connection, etc., and no specific limitation is made here.

[0070] In some other embodiments, the second housing 20 may also include only a second inner housing 21 and a second outer housing 22.

[0071] In other embodiments, the second outer shell 22 may also be composed of at least two plate-like structures that cover the second inner shell 21 and together with the second inner shell 21 define at least two mutually spaced cavities. All cavities together constitute the cavity 200.

[0072] In some other embodiments, the second irregular shell 23 may also be plate-shaped and only cover part of the side surface of the second outer shell 22.

[0073] It should be noted that the specific shape of the second irregular shell 23 can be set to a specific logo, or it can be flexibly set according to the user's needs, and no specific limitation is made here.

[0074] In some other embodiments, the lighter protective case 1 may also have multiple second irregular shells 23 of different shapes. Users can flexibly choose to assemble different shaped second irregular shells 23 on the second outer shell 22 according to their own preferences, so as to further enhance the fun of the lighter protective case 1 and increase the user's user experience.

[0075] In some other alternative embodiments, the second irregular shell 23 can also be integrally formed with the second outer shell 22 into a single structure. That is, when the second shell 20 only includes the second inner shell 21 and the second outer shell 22, an irregular protrusion structure can be provided on the second outer shell 22 to achieve a decorative effect.

[0076] like Figure 7 and Figure 8 As shown, in some embodiments, the control component 30 may include a first circuit board 31 and at least two charging electrodes 32. The first circuit board 31 is equipped with a control circuit module for controlling the operation of the lighter protective case 1. The charging electrodes 32 are electrically connected to the first circuit board 31 for connection to a charger, data cable, or charging cable, facilitating charging of the lighter protective case 1 or data connection to other electronic devices.

[0077] Specifically, please refer to the following: Figure 4 The first circuit board 31 and the charging electrode 32 are both disposed within the first cavity 101. The charging electrode 32 is sheet-shaped and attached to the first circuit board 31. A magnetic charging base is provided on the first outer shell 12 corresponding to the position of the charging electrode 32. The charging electrode 32 can be exposed through the magnetic charging base so that the pins of the charger, data cable, or charging cable can be inserted into the magnetic charging base and electrically connected to the charging electrode 32, and then electrically connected to the control circuit module on the first circuit board 31.

[0078] It should be noted that the lighter protective case 1 in the relevant technology typically does not house electronic components. Even if electronic components are present in the lighter protective case 1 of the relevant technology, the corresponding charging terminals are mostly protruding terminals such as USB. Protruding charging terminals occupy a large amount of space, which is not conducive to the miniaturization of the lighter protective case 1.

[0079] This application reduces the space occupied by the charging electrode 32 in the mounting cavity 100 or cavity 200 by setting it in a sheet shape, thereby facilitating the miniaturization of the lighter protective shell 1 and increasing its thinness. By directly attaching the charging electrode 32 to the first circuit board 31, it eliminates the need for additional conductive structures such as wires and pins between the first circuit board 31 and the charging electrode 32, thus simplifying the number of components and reducing costs.

[0080] By providing a magnetic charging base on the first housing 12, when a magnetic structure is provided at the connection end of the charger, data cable, or charging cable, the base can be magnetically attracted to the magnetic structure at the connection end of the charger, data cable, or charging cable, thereby improving the stability of the connection between the lighter protective case 1 and the charger, data cable, or charging cable.

[0081] In some embodiments, the magnetic charging dock includes at least two charging ports 121 and at least one first magnetic element 70. The at least two charging ports 121 are disposed on the second housing 22 and are respectively disposed corresponding to the charging electrodes 32. The charging electrodes 32 are exposed through the charging ports 121, allowing the prongs of the charger, data cable, or charging cable to extend through the charging ports 121 into the first housing 12 and electrically connect to the charging electrodes 32. The first magnetic element 70 is disposed within the first housing 10 and is used to generate a magnetic attraction force with the magnetic structure on the connection end of the charger, data cable, or charging cable.

[0082] exist Figure 4 In the illustrated embodiment, there are two charging electrodes 32 and two charging ports 121. The two charging electrodes 32 are spaced apart along the first direction X to correspond to the two pins of the charger, data cable, or charging cable. There are two charging ports 121, which are spaced apart along the first direction X on the sidewalls of the first housing 12 and the first cavity 101 respectively.

[0083] It should be noted that the charging electrode 32 is attached to the first circuit board 31, which can be achieved by existing methods such as electroplating and soldering, and no specific limitation is made here.

[0084] It should be noted that the specific shape of the sheet-like charging electrode 32 can be circular, rectangular, polygonal, elliptical, irregular, or other shapes, and is not specifically limited here.

[0085] The charging electrode 32 can be configured to be relatively small in size, so that it is roughly in the shape of a contact. Of course, the charging electrode 32 can also have a certain size, so that it is in the shape of a sheet with a more obvious shape. There is no specific limitation here.

[0086] The shape and size of the charging socket 121 can be adapted to the shape of the prongs on the charger, data cable, or charging cable to facilitate placement and provide a guiding effect. Of course, the shape and size of the charging socket 121 can also be different from the shape of the prongs on the charger, data cable, or charging cable. For example, if the prongs are cylindrical, the charging socket 121 can be a rectangular hole.

[0087] It should be noted that the limiting of the first circuit board 31 within the first cavity 101 can be achieved through snap-fit ​​connection, interference fit, rib plate limiting, bolt connection, glue connection, etc., and no specific limitation is made here.

[0088] In some other embodiments, the first circuit board 31 may also be disposed in other cavities.

[0089] In some other embodiments, the charging electrode 32 may also be fixed to the display component 40 or the power supply component, or fixed to the inner wall, bracket, or stiffener of the first housing 10 or the second housing 20, and electrically connected to the first circuit board 31 through conductive structures such as wires.

[0090] In some other embodiments, when the number of pins on the charger, data cable, or charging cable is three, four, or more, the number of charging electrodes 32 and charging sockets 121 may also be three, four, or more.

[0091] In some other embodiments, the charging electrode 32 and the charging socket 121 may also be spaced apart along other directions such as the second direction Y or the third direction Z.

[0092] In some other embodiments, the number of charging sockets 121 may be less than the number of charging electrodes 32. For example, when there are two charging electrodes 32, there is only one charging socket 121. Both charging electrodes 32 are exposed through this single charging socket 121.

[0093] like Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, the first housing 10 or the second housing 20 is provided with at least one receiving groove 122. The first magnetic element 70 is received in the receiving groove 122 and is used to magnetically attract with the magnetic structure on the connection end of the charger, data cable or charging cable to improve the stability of the connection between the lighter protective case 1 and the charger, data cable or charging cable.

[0094] Specifically, there are at least two first magnetic elements 70 and at least two receiving slots 122, and the at least two first magnetic elements 70 are evenly spaced along the circumference of the charging electrode 32. At least two receiving slots 122 are disposed on the first outer casing 12.

[0095] By setting the number of first magnetic elements 70 to at least two and arranging them evenly spaced along the circumference of the charging electrode 32, it is easy to provide uniform magnetic attraction along the circumference, thereby further improving the stability of the connection between the lighter protective case 1 and the charger, data cable, or charging cable.

[0096] exist Figure 4 In the illustrated embodiment, there are two of each of the first magnetic element 70 and the receiving slot 122. The first outer shell 12 is provided with receiving slots 122 at intervals along the first direction X on opposite sides of the two charging electrodes 32, and the two first magnetic elements 70 are respectively embedded therein, so that the two first magnetic elements 70 are arranged at intervals along the first direction X on opposite sides of the two charging electrodes 32.

[0097] It should be noted that the shape of the first magnetic component 70 can be any shape, such as a disc, column, sphere, ellipsoid, hemisphere, polygon, ring, elliptical ring, polygonal ring, irregular ring, or irregular shape, and is not specifically limited here. The shape of the receiving groove 122 can be flexibly adjusted based on the shape of the first magnetic component 70 so that the first magnetic component 70 can be embedded therein.

[0098] In some other embodiments, at least a portion of the receiving groove 122 may also be provided in the form of a hole, penetrating the first outer shell 12 along the thickness direction, and at least a portion of the first magnetic element 70 may be disposed in the hole.

[0099] In some other embodiments, at least a portion of the first magnetic element 70 may be fixed to the first housing 12 by means of adhesive bonding, welding, embedding, etc. Alternatively, at least a portion of the first magnetic element 70 may be completely embedded within the first housing 12.

[0100] In some other embodiments, at least a portion of the receiving slot 122 may also be disposed on the first irregular shell 13 or the first inner shell 11.

[0101] In some other embodiments, when the charging electrode 32 is disposed on the second housing 20, the first magnetic element 70 may also be disposed on the second housing 20.

[0102] In some other embodiments, when there are two first magnetic elements 70, they may also be positioned between the two charging electrodes 32, or at any interval, based on the position of the magnetic structure on the connector of the charger, data cable, or charging cable relative to the pins.

[0103] In some other embodiments, the number of the first magnetic element 70 and the receiving slot 122 may be set to three, four, five, or more, depending on the number and shape of the magnetic structures on the connection end of the charger, data cable, or charging cable.

[0104] See also Figure 7 and Figure 8 In some embodiments, when the position of the first outer shell 12 covered by the first irregular shell 13 coincides with the position of the charging socket 121, at least one second clearance opening 132 may be provided at the position corresponding to the charging socket 121 to make way for the charging socket 121.

[0105] It should be noted that the number of the second clearance openings 132 can be the same as the number of charging sockets 121, or it can be less than the number of charging sockets 121. Alternatively, the number of the second clearance openings 132 can also be the same as the sum of the number of charging sockets 121 and the number of receiving slots 122, so as to make way for both the charging sockets 121 and the receiving slots 122, avoiding the impact of the first irregular shell 13 covering the magnetic attraction force. The shape of the second clearance opening 132 can be adapted to the shape of the charging sockets 121, or it can be different from the shape of the charging sockets 121. No specific limitation is made here.

[0106] For example, in Figure 7 and Figure 8 In the illustrated embodiment, there is one second clearance opening 132, which is generally arranged in a longitudinally elongated ellipse, with its length extending along the first direction X. Both charging ports 121 and both receiving slots 122 are located within the area defined by the second clearance opening 132.

[0107] like Figure 7 and Figure 8 As shown, in some embodiments, the display component 40 may include a display screen 41, a second circuit board 42, and a triggering device. The second circuit board 42 is equipped with a display circuit module for controlling the display operation of the display screen 41. The second circuit board 42 is electrically connected to both the first circuit board 31 and the display screen 41. The triggering device is electrically connected to the display circuit module on the second circuit board 42 and outputs a display screen trigger signal in response to the opening and closing of the first housing 10 and the second housing 20, so that the display circuit module and the control circuit module can control the display screen 41 to perform display operations.

[0108] Specifically, the display screen 41, the second circuit board 42, and at least part of the triggering device are disposed within the third cavity 103 of the mounting cavity 100. The first clearance opening 123 is located on the side wall corresponding to the first outer shell 12 and the third cavity 103, and the display window 131 is located on the side wall corresponding to the first irregular shell 13 and the third cavity 103. The display screen 41 is correspondingly disposed with the first clearance opening 123 and the display window 131. The triggering device is at least partially fixed on the second circuit board 42 and is used to sense the opening and closing of the first shell 10 and the second shell 20, and output display control signals to the display circuit module on the second circuit board 42 and / or the control circuit module on the first circuit board 31 based on the opening and closing of the first shell 10 and the second shell 20.

[0109] By distributing the control circuit module and the display circuit module on two independent circuit boards, the area of ​​a single circuit board can be reduced, thereby reducing the volume of a single cavity of the mounting cavity 100, improving the space utilization of the mounting cavity 100, and facilitating the miniaturization of the lighter protective shell 1.

[0110] It should be noted that the display screen 41 can be implemented using existing screen structures such as LCD (liquid crystal display), OLED (organic light-emitting diode), and E-Ink (electronic ink screen / electrophoresis screen), and no specific limitation is made here.

[0111] It should be noted that the display screen 41 can be used to display logos, animated emoticons, pictures, and other images and text content. It can also display customized animations and other video content, as well as user interface content such as toolbars, control buttons, menus, and touch feedback. Furthermore, it can display multimedia content such as interactive media, and real-time data of the lighter protective case 1. The specific display content can be customized or selected according to the user's needs, or it can be set to fixed display content; no specific limitations are made here.

[0112] It should be noted that the limiting of the second circuit board 42 within the third cavity 103 can be achieved through snap-fit ​​connection, interference fit, rib plate limiting, bolt connection, glue connection, etc., and no specific limitation is made here.

[0113] In some other embodiments, when the display screen 41 is a flexible screen, the display screen 41 may also be disposed in at least two connected cavities.

[0114] In some embodiments, the lighter protective case 1 may also include at least one ribbon cable 90, through which the first circuit board 31 and the second circuit board 42 can be electrically connected to ensure the neatness of the wiring layout in the mounting cavity 100 and improve space utilization.

[0115] Specifically, please refer to the following: Figure 5The ribbon cable 90 can run clockwise from the second circuit board 42 inside the third cavity 103, passing sequentially through the second cavity 102 and the fourth cavity 104, to connect to the first circuit board 31 inside the first cavity 101. Alternatively, it can run counterclockwise from the second circuit board 42 inside the third cavity 103 directly to the first circuit board 31 inside the first cavity 101. No specific limitation is made here.

[0116] The electrical connection between the power supply component and the first circuit board 31 can also be achieved by setting up the ribbon cable 90.

[0117] In some embodiments, the second housing 20 may include a first position and a second position during the movement of the second housing 20 relative to the first housing 10.

[0118] like Figure 1 As shown, when the second housing 20 is in the first position relative to the first housing 10, the receiving cavity 60 is opened, and the lighter protective case 1 is in the open state. In this open state, the lighter 2 can be placed in the receiving cavity 60 or taken out from the receiving cavity 60.

[0119] like Figure 2 As shown, when the second housing 20 is in the second position relative to the first housing 10, the receiving cavity 60 is closed, and the lighter protective case 1 is in the closed state. In this closed state, the lighter 2 cannot be removed from the receiving cavity 60, or cannot be placed in the receiving cavity 60.

[0120] It should be noted that when the first housing 10 and the second housing 20 are rotatably connected, if the rotation angle of the second housing 20 relative to the first housing 10 is greater than a first preset value, the second housing 20 can be considered to be in a first position relative to the first housing 10. If the rotation angle of the second housing 20 relative to the first housing 10 is less than a second preset value, the second housing 20 can be considered to be in a second position relative to the first housing 10.

[0121] When the first housing 10 and the second housing 20 are detachably connected, the second housing 20 is considered to be in a first position relative to the first housing 10 when it is detached from the first housing 10. When the first housing 10 and the second housing 20 are assembled together, the second housing 20 is considered to be in a second position relative to the first housing 10.

[0122] The first preset value and the second preset value can be the same or different. It should be understood that since there are many possible rotation angles for the second housing 20, the first position and / or the second position may not be unique. The first preset value and the second preset value can be 0° or greater than 0°.

[0123] In some embodiments, the triggering device may be configured to output a first display screen trigger signal to the display circuit module on the second circuit board 42 and / or the control circuit module on the first circuit board 31 when the second housing 20 is in a first position relative to the first housing 10, and to output a second display screen trigger signal to the display circuit module on the second circuit board 42 and / or the control circuit module on the first circuit board 31 when the second housing 20 is in a second position relative to the first housing 10.

[0124] The display circuit module on the second circuit board 42 and / or the control circuit module on the first circuit board 31 can be configured to control the display screen 41 to display the set image when a first display trigger signal is received. When a second display trigger signal is received, the display screen 41 is controlled to continue displaying for a first preset time and then turn off.

[0125] By setting a trigger device and having it work in conjunction with the control circuit module and the display circuit module, the display screen 41 automatically displays and turns off when the second housing 20 is in different positions. This allows users to clearly distinguish the on / off state of the lighter protective case 1, while also adding fun to the process of opening and closing the lighter protective case 1 and improving the user experience.

[0126] In some other embodiments, the display circuit module on the second circuit board 42 and / or the control circuit module on the first circuit board 31 may also be configured to control the display screen 41 to immediately turn off upon receiving a second display screen trigger signal. Alternatively, they may be configured to control the display screen 41 to display a first preset content for a second preset time upon receiving a first display screen trigger signal, and to control the display screen 41 to display a second preset content for a third preset time upon receiving a second display screen trigger signal.

[0127] In some other embodiments, the triggering device may also be configured to output only the first display screen trigger signal. In this case, the display circuit module on the second circuit board 42 and / or the control circuit module on the first circuit board 31 may also be configured to control the display screen 41 to display the first preset content for a second preset time upon receiving the first display screen trigger signal. Alternatively, upon receiving the first display screen trigger signal, after waiting for a fourth preset time, control the display screen 41 to display the first preset content for a second preset time.

[0128] In some other embodiments, the triggering device may also be configured to output only a second display screen trigger signal. In this case, the display circuit module on the second circuit board 42 and / or the control circuit module on the first circuit board 31 may also be configured to control the display screen 41 to display second preset content for a third preset time upon receiving the second display screen trigger signal. Alternatively, upon receiving the second display screen trigger signal, after waiting for a fifth preset time, control the display screen 41 to display the second preset content for a third preset time.

[0129] It should be noted that the first, second, third, fourth, and fifth preset times can be flexibly set according to the user's needs, or can be fixed durations. For example, they can be 3 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds, etc., and no specific limitation is made here.

[0130] like Figure 6 and Figure 7 As shown, in some embodiments, the triggering device may include a Hall element 43 and a magnet (not shown). One of the Hall element 43 and the magnet is disposed on the first housing 10, and the other is correspondingly disposed on the second housing 20. The Hall element 43 can be mechanically and / or electrically connected to the second circuit board 42, and electrical signals can be transmitted between the Hall element 43 and the display circuit module on the second circuit board 42.

[0131] When the second housing 20 is in the first position relative to the first housing 10, the Hall element 43 is far from the magnet, and the Hall element 43 is unaffected by the magnetic field, thus remaining in a non-conductive state. When the second housing 20 is in the second position relative to the first housing 10, the Hall element 43 is close to the magnet, and the Hall element 43 is activated by the magnetic field, becoming conductive. Once activated, the Hall element 43 can output an electrical signal to the second circuit board 42.

[0132] It should be noted that the Hall element 43 and the magnet are positioned such that, when the second housing 20 is in the first position, the Hall element 43 and the magnet are spaced apart from each other. When the second housing 20 is in the second position, the Hall element 43 and the magnet are close to or abut against each other. That is, the Hall element 43 and the magnet can be respectively positioned at the ends of the first housing 10 and the second housing 20 that are close to each other when they are closed.

[0133] For example in Figure 6 In the illustrated embodiment, the Hall element 43 is fixed to the second circuit board 42 and is fixed along the first direction X to one end of the second circuit board 42 near the second housing 20, approximately at the end face of the first housing 10 near the second housing 20 along the first direction X. The magnet is disposed at the end face of the second housing 20 near the first housing 10 along the first direction X.

[0134] Specifically, the second housing 20 may have a receiving groove on its end face near the first housing 10 along the first direction X, and the magnet may be received in the receiving groove. Alternatively, the magnet may be embedded in the second housing 20.

[0135] In some other embodiments, the Hall element 43 and the magnet may also be disposed on one side of the first cavity 101, or the second cavity 102, or the fourth cavity 104, and electrically connected to the display circuit module on the second circuit board 42 through electrical signals, wires, etc.

[0136] In some other alternative embodiments, the triggering device may also be configured as a reed switch, pressure sensor, photoelectric sensor, reed switch or other types of switch structure, which may be disposed on the first housing 10 or the second housing 20 and mechanically and / or electrically connected to the second circuit board 42, and the two can transmit electrical signals.

[0137] In some other embodiments, the triggering device may also be at least partially fixed to the first housing 10 and / or the second housing 20, and electrically connected to the display circuit module on the second circuit board 42 or to the control circuit module on the first circuit board 31 via wires and / or conductive terminals.

[0138] like Figure 7 and Figure 8 As shown, in some embodiments, the power supply component may include a battery cell 50 and a power supply circuit (not shown in the figure). The power supply circuit may be disposed on the first circuit board 31, and the battery cell 50 may be electrically connected to the power supply circuit via a wire or ribbon cable 90.

[0139] The battery cell 50 can be an existing lithium battery, which is lightweight, small in size, easy to carry and integrate into the lighter protective case 1, a small device.

[0140] In some other embodiments, the power supply assembly may also include a third circuit board, on which the power supply circuit module may be disposed and electrically connected to the control circuit module on the first circuit board 31 via a ribbon cable 90.

[0141] In some other embodiments, the lighter protective case 1 may include only one or two of the first circuit board 31, the second circuit board 42, and the third circuit board. For example, when the lighter protective case 1 includes only the first circuit board 31, the display circuit module and the power supply circuit module are both arranged on the first circuit board 31, and the display screen 41 and the battery cell 50 are electrically connected to the circuit on the first circuit board 31 through wires.

[0142] It should be noted that the control circuit module, display circuit module, and power supply circuit module can all be implemented using existing circuit structures, such as existing MCU controllers, Micro-OLED microdisplay controllers, and power management chips (PMICs), etc., without any specific limitations.

[0143] like Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, the lighter protective case 1 may also include at least one adjustment switch 80. The adjustment switch 80 is electrically connected to the control circuit module on the first circuit board 31, and is used to allow the user to input control information to the control circuit module, select or change the operating mode, etc.

[0144] For example, the control circuit module or display circuit module may store display information of at least two displays 41 (such as different animation types, different light colors, different light combinations, etc.), and the adjustment switch 80 may adjust the display information output by the display 41.

[0145] exist Figure 4 In the embodiment shown, the adjustment switch 80 is a push-button switch, which is pressed onto the first housing 12, at least partially located inside the mounting cavity 100, and partially exposed outside the first housing 10, so that the user can operate it by pressing.

[0146] Specifically, the adjustment switch 80 is generally located on the side of the first housing 12 corresponding to the first cavity 101, and is located at the end of the charging electrode 32 near the second housing 20 along the first direction X.

[0147] In some other alternative embodiments, the regulating switch 80 may also be disposed on other circuit boards such as the second circuit board 42 or the third circuit board, or a separate circuit board may be provided to install the regulating switch 80. Correspondingly, it may also be disposed on the side of the first housing 10 corresponding to the second cavity 102, the fourth cavity 104, and the third cavity 103, or disposed on the second housing 20.

[0148] In some other alternative embodiments, the regulating switch 80 may also be a slide switch, toggle switch, rotary switch, coded switch, touch switch, or other existing switch forms.

[0149] In some embodiments, a magnet or snap-fit ​​structure may be provided on the end face of the first housing 10 that contacts the second housing 20. The magnetic attraction or snap-fit ​​connection between the two can achieve the stability of the closed state of the two in the second position, and prevent the lighter 2 from falling off due to the automatic opening of the receiving cavity 60.

[0150] This application also provides a lighter protection device, which may include a power transmission mechanism (not shown in the figure) and the lighter protective shell 1 in any of the foregoing embodiments.

[0151] The power transmission mechanism may include at least two pins for insertion into the magnetic charging base and electrical connection to the charging electrode 32 to charge the lighter protective case 1.

[0152] It should be noted that the power transmission mechanism can be any electronic device with power transmission function, such as a charger, charging cable, or conductive wire, and is not specifically limited here.

[0153] In some embodiments, when the lighter housing 1 includes at least one first magnetic element 70, the power transmission mechanism may further include at least one second magnetic element. The relative positional relationship between the second magnetic element and the pin is adapted to the relative positional relationship between the first magnetic element 70 and the charging electrode 32. When the power transmission mechanism is inserted into the lighter housing 1, the second magnetic element and the first magnetic element 70 are magnetically attracted to each other to ensure the stability of the connection between the power transmission mechanism and the lighter housing 1.

[0154] Specifically, targeting Figure 4 The lighter protective case 1 shown can have two second magnetic components and two pins, which are respectively arranged on opposite sides of the two pins along the interval direction of the two pins, corresponding to the two first magnetic components 70.

[0155] In some other embodiments, the number of pins may correspond to the number of charging electrodes 32, and may be set to three, four, five, or more. The number of the second magnetic element may also correspond to the number of the first magnetic element 70, and may be set to three, four, five, or more.

[0156] In some other embodiments, the number and / or shape of the second magnetic element may differ from that of the first magnetic element 70. For example, the number of the second magnetic element may be one, in a ring shape, and disposed on the outer periphery of the pin. The number of the first magnetic element 70 may be at least two, correspondingly disposed on the outer periphery of the charging electrode 32 along the circumferential direction, etc.

[0157] It should be noted that the first magnetic component 70 and the second magnetic component can be two magnets with opposite magnetic poles. Alternatively, one of them can be a magnet, and the other can be a metal or alloy with magnetic attraction, such as iron. No specific limitations are made here.

[0158] like Figure 1 As shown, this application also constructs a lighter system, which may include a lighter 2 and a lighter protective shell 1 as in any of the foregoing embodiments. The lighter 2 is detachably disposed within the receiving cavity 60 of the lighter protective shell 1.

[0159] Furthermore, the lighter system may also include the power transmission mechanism found in any of the foregoing embodiments.

[0160] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0161] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application's patent. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of this application, and can also make several modifications and improvements, all of which fall within the protection scope of this application. Therefore, all equivalent transformations and modifications made within the scope of the claims of this application should fall within the coverage of the claims of this application.
