Description

Technical Field

[0001] This application relates to the technical field of electronic cigarette devices, and in particular to a split-type electronic cigarette output power regulator. Background Technology

[0002] Electronic cigarettes, as a portable nicotine delivery system, have experienced rapid development in recent years. With consumers' growing demand for personalized experiences, electronic cigarettes have not only innovated in appearance design but also made numerous improvements in functionality and technology. Especially for users seeking a high-quality vaping experience, the ability to flexibly adjust output power has become a crucial requirement. However, most electronic cigarette products on the market currently have a fixed output voltage, which limits the user experience and makes product adjustment inconvenient.

[0003] Existing methods for adjusting the power of electronic cigarettes mainly fall into two categories: one is to preset several fixed output voltage levels through hardware circuitry, and the other is to set several predetermined power values ​​through built-in software. The former is simple and reliable, but it only provides limited options; the latter can add new power options through firmware updates, but it still has certain limitations in practical applications, such as the need for frequent firmware upgrades and dependence on specific hardware platforms.

[0004] Neither of these two methods can meet users' needs for more precise and flexible power adjustment. Especially when users want different suction experiences in different scenarios, existing fixed power levels or preset power values ​​often cannot fully match personal preferences, leading to a poor user experience. Furthermore, because the output power cannot be adjusted in real time, the product faces a lengthy debugging phase, requiring repeated confirmation to find the most suitable configuration. Therefore, there is an urgent need for a device that can achieve stepless adjustment of output power to improve user satisfaction and shorten debugging time. Utility Model Content

[0028] The following will be combined with the appendix Figure 1 The technical solutions in the embodiments of this utility model are clearly and completely described herein. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model.

[0029] The inventors of this application discovered that the output voltage of conventional electronic cigarettes cannot be arbitrarily modified, resulting in limited power options for customers, a poor user experience, and lengthy product debugging cycles requiring repeated confirmation. Therefore, this application primarily employs a split-type electronic cigarette output power regulator, which allows for stepless adjustment of the electronic cigarette power via the charging port. This provides customers with a better vaping experience, shortens debugging time, and quickly matches the appropriate power, thereby improving user satisfaction and production efficiency. A further detailed description of this application follows.

[0030] Example 1

[0031] This application provides a split-type electronic cigarette output power regulator, including a charging port, a voltage regulation module, a control module, and a data communication interface. The charging port is used to connect to an external power source; the voltage regulation module is connected to the charging port and is used to receive power from the external power source and regulate the output voltage; the control module is connected to the voltage regulation module and is used to control the output voltage value of the voltage regulation module; the data communication interface is connected to the control module and is used to transmit control commands and data information.

[0032] Specifically, the charging port can use a common USB Type-C interface or other standard charging interfaces, such as Micro USB or Lightning. These interfaces are versatile and easy to plug and unplug, allowing for interchangeable use with various devices. To improve safety and reliability, the charging port can also be equipped with reverse connection protection circuitry to prevent damage caused by incorrect insertion. For example, a diode can be added to the charging port as a unidirectional conducting element, automatically cutting off the circuit when current flows in the opposite direction, preventing damage to the internal circuitry.

[0033] The voltage regulation module is the core component of the entire regulator, responsible for converting the external power supply voltage into the required output voltage. A voltage regulation module typically consists of a switching regulator (such as a Buck converter) and a feedback circuit. The switching regulator uses high-speed switching devices (such as MOSFETs) to step down the voltage, while the feedback circuit monitors the output voltage and compares it with a set value, maintaining output voltage stability by adjusting the switching frequency and duty cycle. Furthermore, the voltage regulation module can integrate overcurrent and short-circuit protection functions to ensure that the circuit will not burn out under abnormal conditions.

[0034] The control module is the "brain" of the entire system. It is responsible for receiving input signals from the operation buttons and interacting with external devices through a data communication interface. Control modules are typically based on microcontroller units (MCUs), such as the STM32 series or ATmega series chips. These MCUs have abundant peripheral resources, such as communication interfaces like UART, SPI, and I2C, enabling easy connection to various sensors and actuators. Especially in data communication, the control module supports half-duplex communication mode, allowing simultaneous sending and receiving of data, improving communication efficiency and response speed.

[0035] The data communication interface uses a TTL communication interface and supports half-duplex communication mode. Specifically, a data frame begins with a synchronization signal. The data signal is 8 bits, with each bit represented by a 300µs low level and a 900µs high level to indicate 1, or a 900µs low level and a 300µs high level to indicate 0. This encoding method is called Manchester encoding and has good anti-interference capabilities. The end signal is a low level for 1000µs, marking the end of a data frame. Each data frame consists of a protocol header of 0x55, a data length of 0x04, three bytes of data content, and a CRC check byte to ensure the accuracy and integrity of data transmission.

[0036] The display screen connects to the control module and displays the currently set voltage value. The display can be either an LCD or OLED screen; the former has lower power consumption and is suitable for extended use, while the latter offers better display quality and more vibrant colors. In addition to displaying voltage values, the display can also show battery level, fault status, and other information, allowing users to easily monitor the device's operating status.

[0037] The operation buttons connect to the control module and are used to input voltage adjustment commands. The operation buttons include plus / minus buttons and a confirmation button. The plus / minus buttons adjust the output voltage value; each press increases or decreases the voltage by a certain amount, such as 0.1V. The confirmation button confirms the voltage setting. Quickly pressing the confirmation button three times consecutively enters the setting mode, at which point the voltage value on the display will flash, indicating that it is waiting for the user to input a new voltage value. In this way, users can easily adjust the output power of the electronic cigarette without complicated operating procedures. The regulator's OK button flashes when pressed three times consecutively. The plus / minus buttons can be used to increase or decrease the voltage parameter. When connected to the USB input terminal of the device to be adjusted, pressing the OK button will display the currently set voltage value on the adjusted device, indicating successful setting.

[0038] The implementation principle of this embodiment is as follows:

[0039] 1. Flexibility and convenience: With the design of the charging port and voltage adjustment module, users can adjust the output power of the e-cigarette anytime and anywhere without replacing hardware or upgrading firmware, which greatly improves the convenience and flexibility of use.

[0040] 2. Safety: The reverse connection protection circuit and overcurrent protection function effectively prevent damage caused by misoperation and extend the service life of the equipment.

[0041] 3. Accuracy: The use of TTL communication interface and Manchester encoding method ensures the accuracy and reliability of data transmission and avoids errors caused by signal interference.

[0042] 4. User-friendliness: The design of the display screen and operation buttons allows users to intuitively see the current voltage value and make adjustments through simple button operations, greatly improving the user experience.

[0043] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
