Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a replaceable cartridge electronic cigarette holder that is easy to assemble and maintain. Background Technology

[0002] Pod-based electronic cigarettes are popular due to their ease of use and variety of flavors. They typically consist of two parts: a rechargeable device and replaceable cartridges. The device usually contains core components such as a battery, control circuit board, airflow sensor, and charging interface.

[0003] Currently, most mainstream, easy-to-assemble and maintain refillable e-cigarette devices on the market use a traditional soldering method for the electrical connection between the internal battery and the control circuit board. This involves directly soldering the positive and negative terminals of the battery to the corresponding pads on the circuit board via wires. This connection method has several significant drawbacks:

[0004] 1. Low assembly efficiency: On the production line, the welding process requires precision equipment and skilled workers, which increases production time and labor costs, and is not conducive to automated large-scale production.

[0005] 2. Difficult and costly repairs: When either the battery or the circuit board inside the e-cigarette malfunctions, disassembly and replacement are extremely difficult due to their rigid welded connection. Specialized tools and skills are often required to desolder the solder joints, which can easily cause irreversible damage to another intact component or surrounding structure during the repair process (such as burning the circuit board or damaging the battery casing). This results in high repair costs or even rendering the entire e-cigarette unusable, violating both environmental and economic principles.

[0006] 3. Yield Risk: There is a risk of incomplete soldering, cold soldering, or over-soldering during the soldering process. These poor connections may lead to problems such as poor product contact, increased power consumption, and functional failure, affecting the final product yield and user experience.

[0007] Therefore, it is necessary to provide a refillable e-cigarette device that is easy to assemble and maintain in order to overcome the above-mentioned defects. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please refer to Figure 1-5 In one embodiment of this utility model, a refillable electronic cigarette holder that is easy to assemble and maintain includes a housing 1, a battery 2 disposed within the housing 1, a control circuit board 3, and a charging interface 4. The control circuit board 3 is electrically connected to the charging interface 4, and the battery 2 is electrically connected to the control circuit board 3 through a pluggable connector assembly 5.

[0030] Based on the above embodiments, the connector assembly 5 includes a battery connector 51 disposed at the output end of the battery 2 and a board-end connector 52 disposed on the control circuit board 3, wherein the battery connector 51 and the board-end connector 52 are mutually plugged and matched.

[0031] Based on the above embodiments, the battery connector 51 is a male connector, and the board-end connector 52 is a matching female connector.

[0032] Based on the above embodiments, the battery connector 51 is a female connector, and the board-end connector 52 is a matching male connector.

[0033] Based on the above embodiments, the output electrode of the battery 2 is connected to the battery connector 51 via a wire.

[0034] Based on the above embodiments, the board-end connector 52 is welded and fixed to the control circuit board 3.

[0035] Based on the above embodiments, the connector assembly 5 is a dual-pin connector, corresponding to the positive and negative terminals of the battery, respectively.

[0036] Example 2

[0037] Please refer to Figure 1-5 This utility model provides a specific embodiment of a refillable electronic cigarette device that is easy to assemble and maintain. The core structure of the device includes a slender cylindrical outer shell 1, which forms the main outline of the product. Inside the inner cavity of the outer shell 1, a battery 2 providing power, a control circuit board 3 responsible for overall logic control and power distribution, and a charging interface 4 for connecting to an external power source are arranged sequentially or in parallel. The control circuit board 3 achieves a stable electrical connection with the corresponding pins of the charging interface 4 through its printed circuitry, thus constructing a complete charging circuit.

[0038] The core improvement of this invention lies in the fact that the power transmission and signal interaction between the battery 2 and the control circuit board 3 are not achieved through direct soldering, a common method in existing technologies. Instead, an electrical connection is achieved through a specially designed, repeatedly pluggable connector assembly 5. This structural change forms the basis for the convenient assembly and maintenance features of this embodiment.

[0039] Specifically, the connector assembly 5 adopts a plug-in structure design, mainly consisting of two parts: a battery connector 51 located at the power output end of battery 2, and a board-end connector 52 fixedly mounted on the control circuit board 3. During final assembly, the operator simply aligns the battery connector 51 and the board-end connector 52 in a specific direction and applies pressure to fully engage them, thus establishing a stable and reliable electrical path. This mating relationship ensures efficient and lossless transmission of current and signals.

[0040] Regarding the specific form of connector assembly 5, this invention provides flexible configuration options. In a preferred embodiment, the battery connector 51 can be designed as a male connector (i.e., with pins), while the board-end connector 52 can be designed as a precisely mating female connector (i.e., with a socket). This configuration helps to enclose the live pin portion, improving safety. Of course, as an equivalent alternative, the battery connector 51 can also be designed as a female connector, while the board-end connector 52 can be designed as a matching male connector. This design flexibility allows for the selection of the most suitable configuration based on internal space layout and safety considerations.

[0041] On the battery 2 side, its positive and negative output electrodes are first led out through high-temperature resistant and well-insulated wires. The ends of these wires are securely connected to the terminals on the back of the battery connector 51 through reliable processes such as welding and crimping, thereby leading the battery's power to the connector interface.

[0042] On the control circuit board 3 side, the board-end connector 52 is soldered and fixed to the preset pad positions on the control circuit board 3 through its own pins using surface mount technology (SMT) or through-hole soldering technology (THT). These pad positions are connected to the power input terminal, ground terminal, and possible signal detection terminal on the motherboard through copper foil traces inside the circuit board.

[0043] Furthermore, in this embodiment, the connector assembly 5 preferably adopts a standard dual-pin connector. One pin is used to transmit the positive (VCC) current of the battery, and the other pin is used to transmit the negative (GND) current of the battery, thereby completing the power supply circuit simply and efficiently. The use of this standardized component not only ensures the reliability of the connection, but also reduces procurement and production costs.

[0044] The above detailed description is a specific description of one feasible embodiment of the present utility model. However, the embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the spirit of the present utility model should be included in the patent scope of this case.
