Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and more specifically, to a wireless charging electronic cigarette with magnetic attraction function. Background Technology

[0002] E-cigarettes are electronic products used for smoking cessation and as a substitute for traditional cigarettes. Also known as virtual cigarettes, e-cigarettes typically work by vaporizing a liquid within an atomizer to produce vapor. Once the battery is depleted, the e-cigarette cannot be used and needs to be recharged. Traditional charging methods require the battery to be directly connected to a charger or charging cable. While current e-cigarettes have addressed the cumbersome connection issue with wireless charging, they are still inconvenient to carry as they may bump into other objects.

[0003] For example, Chinese patent CN210869896U discloses a wireless charging e-cigarette, which includes an e-cigarette body and a wireless charging transmitter. The e-cigarette body connects to the battery via a wireless receiving module inside the casing and a wire, achieving interface-free wireless charging, making the product more aesthetically pleasing and enhancing the user experience. While this wireless charging e-cigarette achieves interface-free wireless charging and solves the problem of cumbersome connections during charging, in daily activities such as travel, exercise, or work, people often need to carry the e-cigarette and other items like mobile phones simultaneously. However, during physical movement, the e-cigarette and other items are prone to collisions due to body movement, especially items with metal materials. This not only generates noise interference but may also cause scratches and wear on the surface of the items. Furthermore, there is a risk of loss when carrying the e-cigarette alone.

[0011] As an improvement to the wireless charging e-cigarette, the inner side of the second outer shell has an annular protrusion, which encloses a receiving space, and the wireless charging module is fixedly disposed in the receiving space.

[0012] As an improvement to the wireless charging e-cigarette, the annular protrusion has an opening, making the annular protrusion a semi-closed ring structure.

[0013] As an improvement to the wireless charging e-cigarette, the annular protrusion is recessed circumferentially to form an annular groove, the magnet is embedded in the annular groove, and the shape of the magnet matches that of the annular groove.

[0014] As an improvement to the wireless charging e-cigarette, the main body of the e-cigarette is located in the upper part of the cavity of the housing, and the battery is located below the main body of the e-cigarette.

[0015] As an improvement to the wireless charging electronic cigarette, the main body of the electronic cigarette includes an atomizer, a mouthpiece, and a control motherboard.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] A wireless charging e-cigarette with magnetic attraction, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a housing 1 and an electronic cigarette body 2 disposed within the housing 1. The electronic cigarette body 2 is connected to a battery 3 and a wireless charging module 4. The wireless charging module 4 is installed on the inner wall of the housing 1 and is used to receive external wireless charging signals to charge the battery 3, and to wirelessly supply power to external electronic devices via the battery 3. A magnet 5 is disposed on the inner wall of the housing 1, and the magnet 5 is distributed circumferentially along the wireless charging module 4, so that the electronic cigarette can be detachably attached to an external device with a metal material. Specifically, the wireless charging module 4, installed on the inner wall of the housing 1, has a bidirectional electromagnetic induction function. When an external device emits a wireless charging signal, such as a wireless charger or a mobile phone with wireless bidirectional transmission function, the wireless charging module 4 receives the electromagnetic signal through an internal coil 41, converts it into electrical energy, and charges the battery 3. After the battery 3 stores electrical energy, the wireless charging module 4 can also convert the electrical energy of the battery 3 into a wireless signal through electromagnetic induction and transmit it to an external electronic device, such as a mobile phone or watch with wireless charging function, to achieve wireless power supply to the external device. Magnets 5 on the inner wall of the housing 1 are distributed around the wireless charging module 4. By utilizing the magnetic force between the magnets 5 and the metal material area of ​​the external device, the electronic cigarette can be detachably attached to the metal surface, such as the back of a mobile phone, to form a stable physical connection.

[0026] The e-cigarette attaches to the back of the phone via magnet 5, making it easy for users to carry and reducing the risk of loss. It also frees up their hands, enhancing usability. Simultaneously, the e-cigarette's wireless charging module 4 works with the phone's wireless coil to charge battery 3, or wirelessly charge the phone using battery 3's power. This transforms the e-cigarette from a smoking device into a portable power source for charging other electronic devices, improving battery 3's efficiency, reducing resource waste, and demonstrating environmental friendliness.

[0027] It should be noted that the capacity of the electronic cigarette battery 3 is 10000 mAh, which supports the bidirectional wireless charging function of the wireless charging module 4.

[0028] In some embodiments of this application, a full-screen 6 is provided on the outer surface of the housing 1. The full-screen 6 is located on the side opposite to the wireless charging module 4 and is electrically connected to the control motherboard of the electronic cigarette body 2. Specifically, the full-screen 6 establishes an electrical connection with the control motherboard of the electronic cigarette body 2 through a circuit, serving as a human-machine interface to achieve bidirectional information transmission. The user sends commands to the control motherboard by touching or operating the full-screen 6, such as adjusting the working mode or checking the status. After receiving the signal, the control motherboard parses and executes the corresponding operation, such as controlling the atomizer power and the charging and discharging of the battery 3. The control motherboard transmits device status information, such as the battery 3 power level, charging status, and working mode, to the full-screen 6 through a circuit, which displays the information in graphic and textual form. The full-screen 6 provides an intuitive visual interface, allowing users to directly monitor the device status and adjust parameters through the screen without relying on traditional physical buttons, making operation more convenient and efficient. The full-screen 6 makes the outer surface of the housing 1 more concise and elegant, conforming to modern aesthetics; it also supports customized screen content, such as patterns and text, to meet users' personalized needs and enhance product recognition.

[0029] In some embodiments of this application, the magnet 5 comprises multiple independent magnets arranged in a ring array around the coil 41 of the wireless charging module 4. Specifically, there are six magnets arranged in a ring array around the coil 41 of the wireless charging module 4. Each magnet independently generates a magnetic field, forming a uniformly distributed magnetic field area through the ring arrangement. When the e-cigarette approaches an external device with a metal material, the magnetic fields of each independent magnet generate electromagnetic attraction with the metal surface, causing the e-cigarette to be stably adsorbed onto the surface of the metal device through multi-point magnetic attraction. At the same time, the arrangement of the ring array is adapted to the position of the coil 41 of the wireless charging module 4, ensuring that the magnetic attraction function and the electromagnetic induction process of the wireless charging module 4 do not interfere with each other, realizing the coordinated operation of the magnetic attraction and wireless charging functions.

[0030] Furthermore, the independent magnet layout of the ring array allows the magnetic force to be applied evenly to the surface of the metal device, avoiding the uneven force that may be caused by single-point magnetic attraction, improving adsorption stability, and reducing the risk of e-cigarette falling off.

[0031] In other embodiments, the number of magnets can also be set to 2, 3, 4, 5, 7, 8, 9 or 10 as needed.

[0032] In some embodiments of this application, the magnet 5 is an integrated magnetic ring structure in the shape of a ring. Specifically, the integrated magnetic ring structure in the shape of a ring is distributed as a whole ring magnet 5 along the circumference of the wireless charging module 4, and it generates a continuous and uniform ring magnetic field. When the electronic cigarette is close to an external device with a metal material, the ring magnetic field of the magnetic ring generates an overall adsorption force with the metal surface, so that the electronic cigarette is stably adsorbed to the surface of the metal device by the ring magnetic force; at the same time, the magnetic ring is arranged around the coil 41 of the wireless charging module 4, and its ring structure is adapted to the electromagnetic induction area of ​​the wireless charging module 4, ensuring that the magnetic attraction process does not interfere with the signal transmission of the wireless charging module 4. The magnetic ring is a single integrated structure, which eliminates the need to assemble multiple independent magnets, simplifies the assembly process inside the housing 1, reduces production complexity and cost, and reduces the potential for failure due to loose parts.

[0033] In some embodiments of this application, the housing 1 includes a central frame 11, a first outer shell 12, and a second outer shell 13. The first outer shell 12 and the second outer shell 13 are detachably connected to both sides of the central frame 11, forming the front 14 and the back 15 of the housing 1. A full-screen 6 is embedded in the first outer shell 12, and a wireless charging module 4 and a magnet 5 are disposed inside the second outer shell 13. Specifically, the housing 1 adopts a modular and detachable structure. The central frame 11 serves as the supporting main body, and the first outer shell 12 and the second outer shell 13 are detachably connected and fixed to both sides of the central frame 11, forming the front 14 and the back 15 of the housing 1. The full-screen 6, as the interactive interface of the front 14, is embedded in the first outer shell 12 and communicates with the control motherboard of the internal electronic cigarette body 2 via electrical connection. The wireless charging module 4 and the magnet 5 are integrated as functional components inside the second outer shell 13, respectively realizing wireless charging and magnetic attraction functions. The detachable structure allows each component to be assembled, debugged, or replaced independently. The internal layout is optimized through spatial partitioning to ensure that the interactive interface of the front 14 and the functional modules of the back 15 do not interfere with each other. As the capacity of battery 3 increases, the volume of battery 3 also increases. The modular and detachable structure of housing 1, consisting of central frame 11, first outer shell 12, and second outer shell 13, makes it easier to install battery 3 and provides more storage space for battery 3.

[0034] In some embodiments of this application, such as Figure 4As shown, the inner side of the second outer shell 13 has an annular protrusion 121, which encloses and forms a receiving space, in which the wireless charging module 4 is fixedly disposed. Specifically, the annular protrusion 121 on the inner side of the second outer shell 13 forms a closed or semi-closed receiving space, using a physical structure to limit and fix the wireless charging module 4: the wireless charging module 4 is embedded in the receiving space, and the inner wall of the annular protrusion 121 matches the outer periphery of the wireless charging module 4, ensuring the positional accuracy and stability of the wireless charging module 4 within the shell 1. The position of the receiving space corresponds to the back surface 15 of the shell 1, which is the magnetic surface, so that when the wireless charging module 4 is attached to an external device, the center of its coil 41 is aligned with the charging area of ​​the external device, ensuring effective transmission of the wireless charging signal. The receiving space formed by the annular protrusion 121 provides rigid support for the wireless charging module 4, preventing the module from shaking inside the shell 1 or shifting due to external impact, improving the structural stability of the device, and ensuring the reliability of the wireless charging function.

[0035] It should be noted that the installation of battery 3 is as follows: first, battery 3 is placed in the receiving area inside the central frame 11, and then the first outer shell 12, the second outer shell 13, and the central frame 11 are combined through detachable connections to form a complete shell 1, avoiding the overall assembly difficulties caused by the large size of battery 3. In addition, the central frame 11, as the supporting body, can optimize its internal structure according to the size of battery 3, such as reserving stepped or open space. The annular protrusion 121 on the inner side of the second outer shell 13 and the structure of the receiving space can be adjusted in size to provide longitudinal or lateral expansion receiving space for battery 3, ensuring that the large battery 3 can be installed stably.

[0036] In some embodiments of this application, the annular protrusion 121 has an opening 123, making the annular protrusion 121 a semi-closed ring structure. Specifically, the semi-closed ring structure of the annular protrusion 121 physically forms a circuit connection channel through the reserved opening 123. The circuits of the wireless charging module 4, such as power lines and signal lines, can be led out from the receiving space through the opening 123 to establish an electrical connection with the control board and battery 3 of the electronic cigarette body 2. The opening 123 provides space for the circuit wires to pass through, so that after the wireless charging module 4 is fixed in the receiving space, it can still realize power transmission and signal interaction through the opening 123, that is, the control board can regulate the working mode of the wireless charging module 4. Therefore, there is no need to make additional holes in other parts of the housing 1, simplifying the wiring process and reducing the assembly complexity; at the same time, the wires are fixed to the edge of the annular protrusion 121 through the opening 123, reducing the risk of shaking or displacement and improving the stability of the electrical connection.

[0037] In some embodiments of this application, the annular protrusion 121 is recessed circumferentially to form an annular groove 122, and the magnet 5 is embedded in the annular groove 122, with the shape of the magnet 5 matching that of the annular groove 122. Specifically, the inner wall contour of the annular groove 122 formed by the circumferential recess of the annular protrusion 121 matches the shape of the magnet 5, and the magnet 5 is fixed in the groove by physical embedding. After the magnet 5 is embedded in the annular groove 122, the inner wall of the groove restricts the movement of the magnet 5, ensuring that the magnet 5 is evenly distributed circumferentially along the wireless charging module 4 and maintains a preset distance from the outer periphery of the coil 41 of the wireless charging module 4, so as to avoid the magnetic force interfering with the electromagnetic induction process of wireless charging. The shape matching design of the annular groove 122 provides rigid support for the magnet 5, preventing the magnet 5 from shaking inside the housing 1 or falling off due to external impact. This structural arrangement of the annular protrusion 121 achieves the effect of simultaneously providing installation space for the wireless charging module 4 and the magnet 5 and limiting their position, simplifying the structure of the housing 1 and reducing its space occupation.

[0038] In some embodiments of this application, such as Figure 5 As shown, the electronic cigarette body 2 is located on the upper part of the cavity 16 of the housing 1, and the battery 3 is located below the electronic cigarette body 2. Specifically, the electronic cigarette body 2, as the core functional module, is arranged on the upper part of the cavity 16 of the housing 1, allowing the mouthpiece to protrude outward through the top of the housing 1 for easy inhalation by the user; the battery 3, as an energy storage component, is relatively large and needs to be placed stably, so it is arranged below the electronic cigarette body 2, utilizing the bottom space of the housing 1 to provide ample storage area. The battery 3 sinking to the bottom of the housing 1 lowers the overall center of gravity, making it more ergonomic for hand grip and reducing the risk of the device tilting or slipping due to the concentrated weight at the top, making it especially suitable for long-term handheld use.

[0039] In addition, since the battery 3 has a capacity of 10000mAh, the layered layout avoids the space compression caused by stacking the e-cigarette body 2 and the battery 3, and provides independent expansion space for the large-capacity battery 3; at the same time, the atomizer and other heat-generating components are separated from the battery 3, reducing the risk of heat conduction to the battery 3 and improving the safety and lifespan of the device.

[0040] In some embodiments of this application, the electronic cigarette body 2 includes an atomizer, a mouthpiece, and a control board. The atomizer is connected to the mouthpiece, which protrudes outward through the housing 1. The control board is electrically connected to the atomizer and the battery 3. Specifically, the battery 3 supplies power to the control board. The control board adjusts the output current to the atomizer according to a preset program or user operation. After receiving the electrical energy from the control board, the internal heating element of the atomizer heats up, heating and atomizing the e-liquid into vapor. The vapor is then transmitted to the outside of the housing 1 through the connected mouthpiece for the user to inhale.

[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
