Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a cartridge-type electronic cigarette with elastic contact of exposed copper foil on a PCB. Background Technology

[0002] In recent years, with the rapid development of e-cigarette technology, refillable e-cigarettes have gradually become the mainstream in the market due to their convenience and reusability. Existing e-cigarettes typically consist of replaceable cartridges and a device. The cartridges contain atomizing components and a small battery, while the device provides structural support or auxiliary power. However, in practical use, these e-cigarettes still face significant technical bottlenecks, especially insufficient battery life, which severely impacts the user experience.

[0003] First, the limited battery capacity of existing e-cigarette cartridges results in short usage time, requiring users to frequently replace cartridges or interrupt use to recharge, greatly reducing usage continuity. Second, traditional charging methods rely on dedicated interfaces (such as Micro USB or Type-C), which are inconvenient for charging outdoors or in mobile scenarios. More importantly, when the cartridge runs out of power, the e-cigarette device often cannot directly supply power, forcing users to wait for charging to complete, thus interrupting use.

[0004] On the other hand, the integrated design of existing e-cigarettes makes maintenance costs high. If a component in the cartridge or device is damaged, users usually need to replace the entire device, resulting in wasted resources and financial burden. Although some products attempt to improve this issue through modular design, their electrical connection structure is complex, inconvenient to disassemble and assemble, and lacks a reliable positioning and fixing mechanism, making them prone to contact failure due to loosening.

[0005] Therefore, a cartridge-type electronic cigarette with elastic contact of exposed copper on a PCB is provided to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a cartridge-type electronic cigarette with elastic contact of exposed copper on a PCB, which addresses the shortcomings of existing technologies and solves the technical problem of poor battery life in existing electronic cigarettes.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A PCB exposed copper foil elastic contact refillable electronic cigarette includes a cartridge component and a cigarette rod component for use in combination with the cartridge component; the cartridge component includes an upper shell and a lower shell mounted on the upper shell, the lower shell is equipped with a cartridge holder, and the cartridge holder is equipped with an atomizing component for generating smoke.

[0009] The cartridge holder is equipped with a cartridge design for electrical connection with the atomizing component.

The e-cigarette component includes a power supply component and several spring electrodes that are electrically connected to the power supply component. Each spring electrode passes through an insertion hole and contacts a different copper foil layer.

[0010] Furthermore, the cartridge holder is also equipped with a cartridge battery for electrical connection with the cartridge solution.

[0011] Furthermore, a mouthpiece is formed on the top of the upper housing, and a smoke guide channel for communicating with the atomizing component is formed inside the mouthpiece.

[0012] Furthermore, the atomizing component includes an oil cup and a base located at the bottom of the oil cup. The base is provided with a lower seal for sealing it against the inner wall of the oil cup. An oil storage cotton is provided inside the oil cup, and an atomizing core component for heating and atomizing the e-liquid is provided inside the oil storage cotton. A smoke outlet is formed on the top of the oil cup to connect the atomizing core component with the smoke guide channel. An air guide channel is formed on the base to allow outside air to enter the atomizing core component. The cartridge solution is provided with a microphone for detecting the airflow in the air guide channel.

[0013] Furthermore, the top of the oil cup is formed with an oil injection hole, and the top of the oil cup is provided with an upper seal for blocking the oil injection hole; both the upper and lower seals are made of silicone.

[0014] Furthermore, a condensation cotton is provided between the smoke guide channel and the smoke outlet to absorb e-liquid that has not been fully atomized; an oil-absorbing cotton is provided between the bottom of the atomizing core assembly and the air guide channel.

[0015] Furthermore, the smoking rod component includes a smoking rod bracket and a transparent housing mounted on the smoking rod bracket. The power supply component includes a smoking rod design board and a smoking rod battery mounted on the smoking rod bracket. The smoking rod battery is electrically connected to the smoking rod design board, and a plurality of spring electrodes are electrically connected to the smoking rod design board. The ends of the spring electrodes extend to the side of the smoking rod bracket.

[0016] Furthermore, grooves are formed around the periphery of several sockets, and inserts that can be embedded in the grooves are formed around the periphery of several spring electrodes.

[0017] Furthermore, a positioning protrusion is provided on the side of the lower shell with the insertion hole, and the side of the tobacco rod bracket away from the transparent shell is fitted with a tobacco rod cover, and the tobacco rod cover is formed with a positioning groove for the positioning protrusion to be inserted.

[0018] Furthermore, the upper shell side and the lower shell side with the insertion hole are each equipped with a number of first magnets, and the cigarette rod cover is equipped with a number of second magnets for attracting the first magnets.

[0019] The beneficial effects of this invention are as follows: When using this electronic cigarette, the cartridge component is used to heat and atomize the e-liquid into vapor for the user to inhale; the cartridge component can be used alone or in combination with the cigarette holder component; when the cartridge component's power is depleted, the cigarette holder component can be powered and charged through the cigarette holder component, thus improving the electronic cigarette's battery life; in addition, when the cartridge component or the cigarette holder component is damaged, it can be repaired and replaced separately without having to replace the entire electronic cigarette.

[0020] When the cartridge needs to be powered or charged, the spring electrodes on the e-cigarette body are passed through different holes and then into contact with the corresponding copper layer. The spring electrodes conduct electricity, and the power supply component powers the atomizing component, enabling the e-cigarette to be used while also charging, thus improving the user experience and convenience.

[0030] The following is a detailed description of a refillable electronic cigarette with elastic contact of exposed copper foil on a PCB, in conjunction with the accompanying drawings.

[0031] like Figure 1-3 As shown, an embodiment of the PCB exposed copper foil elastic contact refillable electronic cigarette of this utility model includes a cartridge component 1 and a device component 2 for use in combination with the cartridge component 1. When using this electronic cigarette, the cartridge component 1 heats and atomizes the e-liquid into vapor for the user to inhale. The cartridge component 1 can be used alone or in combination with the device component 2. When the battery of the cartridge component 1 is depleted, it can be powered and recharged by the device component 2, improving the battery life of the electronic cigarette. Furthermore, when the cartridge component 1 or the device component 2 is damaged, it can be repaired or replaced individually without requiring the entire electronic cigarette to be replaced.

[0032] like Figure 4-5 As shown, the cartridge component 1 includes an upper shell 11 and a lower shell 12 mounted at the bottom of the upper shell 11. A cartridge holder 13 is installed inside the lower shell 12, and the cartridge holder 13 is equipped with an atomizing component for generating smoke. Additionally, a mouthpiece 111 is formed at the top of the upper shell 11, and a smoke guide channel 112 is formed inside the mouthpiece 111 for communicating with the atomizing component. When the user inhales through the mouthpiece 111, outside air enters the atomizing component. Upon detecting the airflow, the atomizing component is activated, and the generated smoke is guided through the smoke guide channel 112 for the user to inhale.

[0033] In this embodiment, the cartridge holder 13 is also equipped with a cartridge design board 116 (i.e., a PCB board) for electrical connection with the atomizing component. The cartridge design board 116 is arranged vertically, and a plurality of copper foil layers 119 are provided on the surface of the cartridge design board 116. The number of insertion holes 120 formed on the side of the lower housing 12 is the same as the number of copper foil layers 119, and each insertion hole 120 corresponds to a different copper foil layer 119. In addition, the e-cigarette component 2 includes a power supply component and a plurality of spring electrodes 27 electrically connected to the power supply component. The number of spring electrodes 27 is the same as the number of copper foil layers 119. Each spring electrode 27 passes through the insertion hole 120 and contacts a different copper foil layer 119. When the cartridge component 1 and the e-cigarette component 2 are used together, each spring electrode 27 passes through a different insertion hole 120 and contacts the corresponding copper foil layer 119. The spring electrode 27 conducts electricity, and the power supply component supplies power to the atomizing component, enabling the e-cigarette to be used.

[0034] In addition, the cartridge holder 13 is also equipped with a cartridge battery 117 for electrical connection with the cartridge solution version 116. When the cartridge component 1 and the e-cigarette component 2 are not used together, the cartridge battery 117 can power the atomizing component, so that the cartridge component 1 can be used alone. When the cartridge battery 117 is depleted, the spring electrode 27 contacts the copper layer 119, which can not only power the atomizing component, but also charge the cartridge battery 117.

[0035] The mouthpiece 111 is provided with a silicone plug 1111 for blocking the smoke guide channel 112. When the electronic cigarette is not in use, the silicone plug 1111 blocks the smoke guide channel 112 to prevent impurities from entering the interior of the atomizing component and causing damage; it also prevents e-liquid from leaking out of the smoke guide channel 112, thus improving the user experience.

[0036] Furthermore, the atomizing assembly includes an oil cup 15 and a base 14 disposed at the bottom of the oil cup 15. The base 14 is provided with a lower sealing member 16 for sealing it against the inner wall of the oil cup 15. An oil-collecting cotton 17 is disposed inside the oil cup 15, and an atomizing core assembly 18 for heating and atomizing the e-liquid is disposed inside the oil-collecting cotton 17. A smoke outlet 19 is formed on the top of the oil cup 15, which connects the atomizing core assembly 18 to the smoke guide channel 112. The base 14 is formed with an air guide channel 114 that allows outside air to enter the atomizing core assembly 18. When the user inhales through the mouthpiece 111, outside air enters the atomizing core assembly 18 through the air guide channel 114. At the same time, by controlling the operation of the atomizing core assembly 18, the e-liquid is heated and atomized. The air inside the atomizing core assembly 18 carries the smoke out, which is then guided through the smoke guide channel 112 for the user to inhale. In addition, the cartridge solution version 116 is equipped with a microphone 118 for detecting airflow in the airflow channel 114. The microphone 118 is an existing airflow sensor. When the user inhales, the outside air enters the airflow channel 114 and is detected by the microphone 118, which then controls the operation of the atomizing core assembly 18.

[0037] In this embodiment, the top of the oil cup 15 is formed with an oil filling hole, and the top of the oil cup 15 is provided with an upper sealing member 110 for blocking the oil filling hole. Both the upper sealing member 110 and the lower sealing member 16 are silicone parts. When it is necessary to fill the oil cup 15 with oil, the upper shell 11 is first removed from the lower shell 12, and then the upper sealing member 110 is removed from the top of the oil cup 15. Oil is then filled into the oil cup 15 through the oil filling hole. A condensing cotton 113 is provided between the smoke guide channel 112 and the smoke outlet 19 to absorb e-liquid that has not been fully atomized. By providing the condensing cotton 113, leakage of e-liquid that has not been fully atomized from the smoke guide channel 112 is prevented, thus improving the user experience. An oil-absorbing cotton 115 is provided between the bottom of the atomizing core assembly 18 and the air guide channel 114. E-liquid that leaks out of the atomizing core assembly 18 from its bottom is absorbed by the oil-absorbing cotton 115, further preventing e-liquid leakage.

[0038] like Figure 6 As shown, the cigarette rod component 2 includes a cigarette rod bracket 21 and a transparent housing 22 mounted on the cigarette rod bracket 21. The power supply component includes a cigarette rod design plate 23 mounted on the cigarette rod bracket 21 and a cigarette rod battery 25. The cigarette rod battery 25 is electrically connected to the cigarette rod design plate 23. A plurality of spring electrodes 27 are electrically connected to the cigarette rod design plate 23, and the ends of the spring electrodes 27 extend to the side of the cigarette rod bracket 21.

[0039] The periphery of several sockets 120 is formed with grooves 123 (e.g. Figure 2As shown, several spring electrodes 27 have inserts 211 formed on their periphery that can be embedded in grooves 123. When the cartridge component 1 and the cigarette rod component 2 are used together, the inserts 211 are embedded in the grooves 123. At the same time, each spring electrode 27 passes through different insertion holes 120 and contacts the corresponding copper foil layer 119. By setting the inserts 211 and the grooves 123, loosening is prevented during the combined use of the cartridge component 1 and the cigarette rod component 2, thus improving the stability during combined use. In addition, a positioning protrusion 122 is provided on the side of the lower housing 12 where the insertion holes 120 are formed. The cigarette rod bracket 21 is fitted with a cigarette rod cover 28 on the side away from the transparent housing 22. The cigarette rod cover 28 is formed with a positioning groove 29 for the positioning protrusion 122 to be embedded in. Positioning is achieved through the cooperation of the positioning protrusion 122 and the positioning groove 29, which allows several spring electrodes 27 to be precisely inserted into the insertion hole 120. The combined effect of the spring electrodes 27 and the insert 211 embedded in the groove 123 further improves the stability of the combined use.

[0040] Several first magnets 121 are installed on the side of the upper housing 11 and the side of the lower housing 12 where the insertion hole 120 is formed. Several second magnets 210 are installed on the cover 28 of the cigarette rod to attract the first magnets 121. When the cartridge component 1 and the cigarette rod component 2 are used together, the first magnets 121 and the second magnets 210 attract each other to prevent them from separating automatically, thus improving the convenience of use for the user.

[0041] In addition, the e-cigarette device's control panel 23 is also equipped with a digital screen 24 and a charging terminal 26. The charging terminal 26 allows for charging of the e-cigarette device's battery 25. The spring electrode 27 not only conducts electricity but also transmits data. The e-liquid level data is transmitted via the spring electrode 27 to the control panel 23 and then displayed on the digital screen 24, which the user can observe through the transparent casing 22. The digital screen 24 and charging terminal 26 are existing technologies and will not be described in detail here.

[0042] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0043] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
