In the description of this application, "plurality" means two or more, unless specifically and precisely specified.

[0019] In the description of this application, unless otherwise clearly specified and limited, the terms "connection," "connection," and "link" should be understood in a broad sense, and may refer to, for example, a fixed connection, an indirect connection via an intermediate medium, a communication between two elements, or an interactive relationship between two elements. The specific meanings of the above terms in this specification can be understood by those skilled in the art depending on the circumstances.

[0020] In the specification, claims, and drawings of this application, terms such as "first," "second," etc. are used to distinguish between similar objects, not to describe a particular order or priority. Furthermore, the terms "comprise," "include," and similar expressions are intended to cover an inclusion that is not exclusive. For example, a process, method, system, product, or apparatus that includes a series of steps or units need not be limited to those explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to those processes, methods, products, or apparatus.

[0021] An embodiment of the present application provides a voltage-adjustable mobile power supply for air-conditioning clothing with a temperature-regulating unit for cooling or heating. The application scenarios of the air-conditioning clothing are wide, including situations requiring body temperature regulation, such as in high-temperature and low-temperature environments. The mobile power supply according to an embodiment of the present invention specifically includes a housing, a circuit board mounted within the housing, and a battery. The housing is equipped with an operating unit, a charging interface, a discharging interface, and a display panel. The circuit board is equipped with a control circuit. The master charging / discharging main control circuit in the control circuit is connected to the regulating circuit. The regulating circuit feeds back the voltage regulation operating signal of the operating unit to the charging / discharging main control circuit so that the charging / discharging main control circuit increases or decreases the voltage by one unit based on the voltage regulation operating signal, thereby achieving polarity-free voltage regulation. The present invention also provides a detachable buckle that can be connected to the housing. The buckle allows the mobile power supply to be easily attached to pants or other items, eliminating the need for a pocket or bag to store the mobile power supply. When the buckle is not needed, it can be directly removed without affecting the overall volume of the mobile power supply.

[0022] As shown in FIGS. 1 and 2 , the present embodiment of a voltage-adjustable mobile power source for air-conditioning clothing includes a temperature control unit, including, but not limited to, a heat dissipation fan. The mobile power source includes a housing 1, which houses a circuit board 2 and a battery 3. The housing 1 houses an operation unit 4, a charging interface 5, a discharging interface, and a display panel 6. The battery 3, operation unit 4, charging interface 5, discharging interface, and display panel 6 are all connected to a control circuit integrated on the circuit board 2. The housing 1 also includes a detachable buckle 7. Due to the demands of air-conditioning clothing, electrical energy must be provided to regulate the temperature of the clothing. To ensure the clothing's usable life, sufficient battery life is also required. This places a higher demand on the capacity of the mobile power source, and the required capacity is becoming increasingly large. When the mobile power source is placed in the pocket of the air-conditioning clothing, the pocket is likely to sag, causing discomfort. Therefore, this embodiment adds a buckle structure to provide users with two options. The user can place the mobile power supply in a pocket or hang it from a belt. The control circuit includes a charging / discharging main control circuit and a regulation circuit. The discharge interface is connected to the temperature regulation unit, and the operation unit is connected to the charging / discharging main control circuit via the regulation circuit. The regulation circuit feeds back the voltage regulation signal of the operation unit to the charging / discharging main control circuit so that the charging / discharging main control circuit increases or decreases the voltage by one unit based on the voltage regulation signal. In this embodiment, one unit of voltage may be 1 volt, 0.5 volts, 0.1 volts, etc. One unit represents one numerical value. The specific numerical value is determined according to the actual usage situation. The operation unit in this embodiment may be an operation button, an operation knob, or a touch key.

[0023] Specifically, the operation unit 4 includes an up button, a down button, and a switch button connected to the control circuit. The up and down buttons are used to adjust the voltage. For example, the up button corresponds to increasing the voltage, and the down button corresponds to decreasing the voltage. Each time the user manually presses the up or down button, the voltage is adjusted by one step. The voltage adjustment method in this embodiment is discrete-point voltage adjustment. For example, if the current voltage is 10 and one adjustment unit is 1 volt, pressing the up button once will display 11. The voltage display is realized by a display panel. Then, pressing the up button again will adjust the voltage to 12. Then, pressing the down button once will adjust the voltage to 11. The housing 1 includes a case 11 and a cover 12. The case 11 forms an accommodation space and has an opening. The cover 12 closes the opening after being connected to the case 11. The operation unit 4 is mounted on the side of the case 11. The circuit board 2 and the battery 3 are both provided in the aforementioned storage space. The buckle 7 is attached to the side of the case 11 that faces the cover 12. Here, the side of the case 11 is provided with an attachment groove for accommodating the buckle so that the entire outer surface remains flat after the buckle is attached.

[0024] Specifically, the control circuit further includes a discharge circuit, a digital screen display circuit, a voltage conversion module, an MCU power supply module, and an NTC module.
