Description

Technical Field

[0001] This utility model belongs to the technical field of negative ion products, and in particular relates to a portable negative ion generator that is compatible with mobile phones. Background Technology

[0002] Negative oxygen ions have been widely used in the field of air purification due to their bactericidal, disinfecting, and air-purifying properties.

[0003] Negative oxygen ions play a certain role in preventing viruses because they carry a negative charge, while most harmful particles, bacteria, and viruses usually carry a positive charge. When these positively charged particles encounter negative oxygen ions, their charges are neutralized, thereby rendering these harmful substances inactive or reducing their activity, thus reducing their potential threat to the human body.

[0004] However, existing negative ion products have the following drawbacks:

[0005] 1. The equipment is powered by lithium batteries or AC power, which makes it bulky and inconvenient to carry.

[0006] 2. The high voltage (4000V-12000V) of the negative ion emitter can interfere with other equipment or even damage it. The higher the voltage, the stronger the radiation, which can easily cause harm to the human body when in close contact. Summary of the Invention

In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention.

[0037] As attached Figure 1 As shown, this application provides a portable negative ion generator compatible with mobile phones. The device comprises a detachable upper cover 2 and a lower cover 6. The upper cover 2 has a wireless charging area for placing the compatible mobile phone 1. The wireless charging module 200 and the negative ion emitter 800 are disposed inside the lower cover 6. The communication module 400, the negative ion detection module 300, the frequency tracking module 600, the high-voltage generation module 700, the discharge circuit, and the main control chip 500 are integrated on a control circuit board inside the lower cover 6.

[0038] The wireless charging area is embedded in the top of the cover 2, and its size is adapted to the wireless charging sensing area on the back of the phone 1.

[0039] The wireless charging module 200 includes a wireless charging receiving coil 7 and a power control board 5. The wireless charging receiving coil 7 adopts a multi-winding structure to adapt to different mobile phone models. The wireless charging module 200 is communicatively connected to the mobile phone wireless charging system 100 and is used to obtain power through reverse charging of the mobile phone.

[0040] The communication module 400 communicates with the main control chip 500 for exchanging working status and transmitting data with the mobile phone 1. The communication module 400 sends a handshake protocol (such as Bluetooth, Wi-Fi, or a customized protocol) to the mobile phone to verify the legitimacy of the portable negative ion generator compatible with the mobile phone. Upon successful handshake, the mobile phone sends a power-on command to the portable negative ion generator, activating it. The handshake command assigns a specific key based on the mobile phone brand or manufacturer, achieving differentiated authorization.

[0041] The main control chip 500 is connected to the wireless charging module 200. The main control chip 500 is used to receive the battery status data of the mobile phone 1 and distribute power to each functional module. The main control chip 500 is connected to the detection module 300 and dynamically configures the working parameters according to the environmental parameters detected by the detection module 300.

[0042] The detection module 300 includes a MEMS miniature negative ion sensor, a temperature sensor, and a humidity sensor. The MEMS miniature negative ion sensor is used to detect the concentration of negative oxygen ions. The detection module 300 is used to monitor the concentration of negative oxygen ions and other parameters (such as temperature and humidity) in the environment in real time.

[0043] The main control chip 500 configures the optimal operating parameters of the equipment according to environmental parameters. The frequency tracking module 600 automatically adjusts the operating frequency of the high voltage module, so that the high voltage generating module 700 outputs a voltage of no more than 2000V under the control of the main control chip 500. The negative high voltage output by the high voltage generating module 700 ionizes the oxygen in the air through the negative ion emitter 800 to generate negative oxygen ions, so that the voltage of the negative ion emitter 800 is lower than 2000V, avoiding interference and damage to other equipment.

[0044] The main control chip 500 has a built-in negative ion detection module, which includes a negative ion collection plate and a charge amplifier. When the feedback value from the negative ion detection module is lower than a preset threshold, a discharge circuit is activated to release positive charge to maintain space charge balance. Preferably, the discharge circuit includes a MOSFET switch and a discharge resistor network, and the discharge time is controlled between 0.5 and 3 seconds.

[0045] The input terminal of the high-voltage generator module 700 is connected to the main control chip 500, and outputs a voltage not exceeding 2000V under the control of the main control chip 500. Preferably, the high-voltage generator module 700 adopts a push-pull oscillation circuit with an operating frequency range of 50kHz-120kHz.

[0046] The frequency tracking module 600 is connected between the high voltage generator module 700 and the main control chip 500. It monitors the load status of the high voltage generator module 700 in real time and automatically adjusts its operating frequency to the resonant point to ensure that the high voltage generator module 700 is in the optimal efficiency range.

[0047] The negative ion emitter 800 is connected to the output terminal of the high voltage generating module 700 and is used to ionize oxygen in the air to generate negative oxygen ions under the negative high voltage output by the high voltage generating module 700.

[0048] Work process:

[0049] Place your mobile phone 1 on the wireless charging area of ​​the portable negative ion generator (hereinafter referred to as the device) that supports reverse charging. The built-in wireless charging module 200 of the device activates the reverse charging function of the mobile phone 1 through a communication protocol, and the device receives power. At the same time, a handshake protocol is sent through the communication module 400. After the handshake is successful, the mobile phone sends a power-on command (the handshake command is like a key, which can authorize different keys for different mobile phone manufacturers or brands), and the device is powered on.

[0050] After the device is powered on, the detection module 300 (integrating a negative ion sensor, temperature and humidity sensor, etc.) monitors the negative oxygen ion content and other parameters (such as temperature and humidity) in the environment in real time. The detection data is transmitted to the main control chip 500 via the internal bus, and the negative ion detection module of the main control chip 500 analyzes the data.

[0051] If the negative ion concentration is lower than the preset threshold: turn off the negative ion output and drive the discharge circuit to neutralize excess positive charges in the environment to avoid electrostatic interference.

[0052] If the negative ion concentration is normal: the main control chip 500 dynamically configures the working frequency, voltage and other parameters of the high voltage module according to real-time environmental parameters to ensure efficient and stable operation of the system.

[0053] The frequency tracking module 600 monitors the load status of the high voltage generator module 700 in real time and automatically adjusts its operating frequency to the resonant point to ensure that the high voltage generator module 700 is in the optimal efficiency range.

[0054] The main control chip 500 controls the high-voltage generator module 700 to output a DC negative high voltage not exceeding 2000V. The negative high voltage output by the high-voltage generator module 700 ionizes oxygen in the air through the negative ion emitter 800 to generate negative oxygen ions. This can create a small negative ion field around the user (within a 1-meter range), within which viruses will be killed by the negative oxygen ions. The negative ion emitter 800 releases negative ions at low voltage, avoiding interference and damage to other equipment.
