It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0036] like Figures 1 to 4 As shown, this application provides a portable negative ion generator, comprising a housing 1, a negative ion generating module 2, a power supply module 3, a control module 5, and a motion sensor 4, wherein:
[0037] like Figure 3As shown, the housing 1 is assembled from a top shell 11 and a bottom shell 12 by snap-fitting together, forming a closed structure to accommodate internal components. For ease of wear, the overall size of the housing 1 is moderate, suitable for one-handed holding or fixed to the user's body via the hanging component 8. The top shell 11 is provided with several air outlets 6, preferably arranged in a circular perforated matrix structure to facilitate the smooth release of negative oxygen ions. To prevent dust particles in the air from entering the device, a filter screen 7 is embedded in the inner surface of the top shell 11.
[0038] The negative ion generating module 2 is located inside the housing 1, below the air outlet 6. The negative ion generating module 2 includes a discharge needle and a grounding electrode, arranged opposite each other, and can efficiently generate negative ions through corona discharge. The generated negative ions naturally diffuse into the external environment through the air outlet 6 of the top housing 11, thereby improving the air microenvironment around the wearer.
[0039] like Figure 4 As shown, the power module 3 is also located inside the housing 1, providing power to the negative ion generating module 2 and the control module 5. The power module 3 can use a rechargeable lithium battery as its energy source and is equipped with a charging interface, such as a USB Type-C interface, to facilitate users in charging the device and meet the needs of long-term portable use.
[0040] The control module 5 is electrically connected to the power supply module 3, and is used to receive power and control the start and stop of the negative ion generating module 2. The control module 5 integrates a microcontroller to process the motion status signals transmitted by the motion sensor 4, and makes intelligent decisions on whether to turn the negative ion generating module 2 on or off based on different states, thereby realizing automated control and improving the intelligence and convenience of the equipment.
[0041] Motion sensor 4 is housed within housing 1 and electrically connected to control module 5. Motion sensor 4 can be an accelerometer, gyroscope, or a combination thereof, capable of monitoring the movement status of the portable negative ion generator in real time. Specifically, when the device is detected to be moving, control module 5 determines that the device is being worn and used, thereby controlling negative ion generator 2 to start releasing negative ions; when the device is detected to be stationary for a preset time threshold, control module 5 shuts down negative ion generator 2 to extend battery life and improve safety.
[0042] like Figure 1 and Figure 2 As shown, to facilitate users in wearing or fixing this portable negative ion generator in different positions, a hanging component 8 is fixedly provided on the bottom shell 12. The hanging component 8 can be Velcro, a lanyard, or other easily detachable connection structure. Users can choose to hang the device around their neck, wear it on their chest, clip it to their waist, or fix it to a backpack shoulder strap, etc., to meet the wearing needs of various usage scenarios.
[0043] This application achieves a comprehensive effect of portable negative ion release, intelligent start / stop, convenient wear, and long battery life through a miniaturized structure and integrated functions. Compared with existing large negative ion devices, this application can continuously improve the air environment around the wearer during daily activities such as walking, commuting, and exercising, improving ease of use and user experience, while reducing energy consumption and enhancing overall safety.
[0044] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
