It employs the latest mesh technology to convert liquid medicine into an ultra-fine mist with a particle size of approximately 3.5μm. This allows the active ingredients to smoothly reach the trachea, bronchi, and alveoli with each breath, enhancing the effect on the deep tissues. [Mesh Part Replacement - Utility Model Registration Technology (No. 3249025)] With the independently developed mesh part replacement technology (Utility Model Registration No. 3249025), you can replace only the mesh cap without replacing the liquid medicine cup. This significantly reduces consumable costs, making it economical. With one included replacement mesh cap, you can immediately replace it and continue using it even if the mist suddenly stops. This instantly eliminates the anxiety of no mist and balances cost reduction and convenience. [Automatic Cleaning Function Prevents Mesh Clogging] After use, simply add distilled water to the liquid medicine cup and long-press the power button to activate the automatic cleaning mode. This effectively washes away the liquid medicine remaining in the mesh part, preventing clogging. It can maintain a clean state for a long time and always demonstrates stable spraying performance.
