Abstract
Description
Technical Field
[0001] This utility model discloses a portable power supply, particularly a multi-purpose wireless portable power supply suitable for hydrogen-rich cups, belonging to the field of small electronic product technology. Background Technology
[0002] A hydrogen-rich cup is a cup that generates hydrogen-rich water, also known as a hydrogen water cup. Current hydrogen-rich cups use water electrolysis to separate hydrogen from the water, resulting in a high concentration of hydrogen gas and thus hydrogen-rich water. Hydrogen has antioxidant properties, neutralizing free radicals in the body, reducing oxidative damage, delaying aging, and potentially helping to prevent various chronic diseases. Some hydrogen-rich cups use magnetic flux magnetization technology, which breaks down ordinary water molecules into smaller clusters, increasing their permeability and making them easier for cells to absorb. Magnetized drinks have reduced astringency and a richer aroma, improving their taste and quality. Therefore, hydrogen-rich cups have been highly sought after since their introduction. However, because the main working principle of a hydrogen-rich cup is water electrolysis, electricity is essential for its use. When using a hydrogen-rich cup outdoors, it can only be operated with the aid of a power bank.
[0003] A power bank, also known as a portable charger, is a portable charger that integrates power supply and charging functions. It is primarily used to charge various portable electronic devices such as smartphones, tablets, and wearable devices in situations where an external power source is unavailable, thus solving the battery life problem for these devices. Building upon the traditional power bank, it adds wireless charging functionality, eliminating the need for a USB cable. As long as the phone being charged supports wireless charging and has a wireless charging receiver coil, wireless charging can be achieved.
[0004] Traditional power banks, whether wired or wireless, continuously discharge once connected to a device until the smartphone, tablet, or wearable device is fully charged or the power bank itself is depleted. However, using a traditional power bank to power a hydrogen-rich cup presents a significant problem: the cup cannot provide feedback. Users must estimate usage time and effectiveness, manually turning off the power bank or removing the cup, causing considerable inconvenience. If a user neglects or forgets to use the cup, the power bank may continue supplying power until it is completely depleted. This can range from simply depleting the power bank and rendering it unusable, to potentially damaging the cup or power bank, or even posing a safety hazard. Summary of the Invention
[0005] In view of the inconvenience and safety hazards of using existing power banks to power hydrogen-rich cups, this utility model provides a multi-purpose wireless power bank suitable for hydrogen-rich cups.

[0041] In this embodiment, the wireless power supply control module uses MCU chip U4. The specific model and series of MCU chip U4 are not limited in this embodiment; any MCU capable of basic timing operations and switching control is sufficient. Most commercially available MCUs can meet these requirements. In this embodiment, one data terminal of MCU chip U4 (PB2 in this embodiment) is connected to one data terminal of MCU chip U1 (TA4 in this embodiment) as TX_DET. The MCU chip U1 transmits a start control signal to MCU chip U4, which then controls the wireless power supply drive module. MCU chip U4 outputs a PWM signal to control the on / off state of the wireless power supply drive module, thereby generating AC power. This AC power is output through the wireless power supply coil L2 to power the hydrogen-rich cup or electronic products.
[0042] In this embodiment, a transmission sensing detection module is connected to the wireless power supply coil L2 to detect whether an electronic product requiring charging or power is placed on the coil.

The output terminal (OUTA) of the operational amplifier U5 is connected to a data terminal of the MCU chip U4 (PB0 is selected in this embodiment). When an electronic product requiring charging or power is placed on the wireless power supply coil L2, capacitor C18 changes, resulting in a signal at the output terminal of the operational amplifier U5. The MCU chip U4 then determines that an electronic product requiring charging or power has been placed on the coil.

[0046] In this embodiment, a foot pad 10 is fixedly installed at the bottom of the lower cover 1.
[0047] This utility model mainly includes two working modes: hydrogen-rich cup mode (i.e., powered by a hydrogen-rich water cup) and electronic product charging mode (i.e., powered by other wireless receiving devices). In specific implementation, more working modes can be set and switched according to actual needs, including:
[0048] (1) Power supply from hydrogen-rich water cup:
[0049] When the hydrogen-rich water cup is placed on this invention, the power indicator light on the cup illuminates. Simultaneously, the automatic sensing device detects the cup and sends information to the MCU chip U4. The MCU chip U4 then sends a signal to the mobile power management module. After the mobile power management module starts, it initiates a voltage boost. The boosted voltage supplies power to the wireless power supply coil (i.e., the transmitting coil) and the transmitting circuit. The wireless connector on the cup receives the transmitted signal and generates a magnetic field resonance. Utilizing Faraday's law of electromagnetic induction, energy is transmitted through the magnetic field coupling between the wireless power supply coil (i.e., the transmitting coil Tx) and the receiving coil (Rx, located inside the cup) to power the hydrogen-producing device in the hydrogen-rich water cup. This invention has a timing function for each energy transmission during resonance. After the estimated time, energy transmission stops, and the hydrogen-rich water cup stops working until the previous action triggers operation again.
[0050] (2) Power supply for other wireless receiving devices:
[0051] Touch the power supply icon on this utility model to light up the power supply indicator light. At this time, place the device to be powered (mobile phone, wireless power bank or other wireless receiving and charging device, etc.) on the surface of this utility model. The working status indicator light will flash, indicating that this utility model has supplied power to the device that needs power. When the power receiving device is saturated, if this utility model detects that the power supply current is less than the preset current inside this utility model, the working status indicator light will stay on to indicate that the power supply is complete.
[0052] In this embodiment, the specific working mode is determined by detecting the load working current. Typically, the working current of the hydrogen production cup is less than or equal to 600 mA, while the charging current of a mobile phone is generally greater than 800 mA.
[0053] When this invention is in operation, the product is woken up by manually touching the wake-up module (i.e., the touch module). (Normally, this invention is in a low-power sleep state.) After each touch to wake the product, it will standby for one minute, and the standby indicator light will be on for one minute. In standby mode, when a hydrogen-rich water cup or mobile phone (or other electronic product) is placed on it, the operating current will be automatically detected. If the current is less than 800 mA, the product will automatically work in hydrogen production mode, the hydrogen production mode blue light will be on, and the hydrogen production work indicator blue light will also be breathing and flashing. The working time is set to 3 minutes. If the load current is greater than 800 mA, the charging mode green light will be on, and the charging indicator green light will be breathing and flashing until the mobile phone is fully charged.
[0054] This utility model is equipped with a wake-up module and a timing module. When powering a hydrogen-rich cup, it can switch to hydrogen-rich cup mode and limit the usage time. When the set time is reached, the power bank will automatically shut off without causing damage. When it switches to electronic product charging mode, it will function like a conventional power bank in the prior art, making its use more versatile.
