Portable Fragrance Diffuser

Abstract

This invention discloses a novel portable fragrance diffuser, comprising: a mounting frame having a first connecting portion, a second connecting portion, and a main board; a liquid storage tank formed below the second connecting portion, on which a pluggable liquid guide strip is mounted; a liquid supply module connected to the first connecting portion, providing an aqueous fragrance solution to the liquid storage tank; an atomizing module installed on the second connecting portion and in contact with the liquid guide strip, generating high-frequency vibration upon energization to atomize and disperse the aqueous fragrance solution from the liquid guide strip into the air; a power module installed on one side of the main board; and a power control circuit installed on the other side of the main board and electrically connected to the atomizing module and the power module, controlled to start and supply power from the power module to the atomizing module.

Claims

1. A portable fragrance diffuser, comprising: a mounting frame having a first connecting portion, a second connecting portion, and a main board, wherein a liquid storage tank is formed below the second connecting portion, and a pluggable liquid guide strip is mounted on the liquid storage tank; a liquid supply module connected to the first connecting portion for supplying a fragrance aqueous solution therein to the liquid storage tank; an atomizing module installed on the second connecting portion and in contact with the liquid guide strip, wherein energizing generates high-frequency vibration to atomize and disperse the fragrance aqueous solution from the liquid guide strip into the air; a power module installed on one side of the main board; and a power control circuit installed on the other side of the main board and electrically connected to the atomizing module and the power module, which is activated under control to supply power from the power module to the atomizing module; A protective housing covers the mounting bracket, the liquid supply module, the power module, and the power control circuit, with the exposed portions of the mounting bracket and the liquid supply module; and a protective cover is detachably connected to the mounting bracket to protect a portion of the liquid supply module.

2. The portable fragrance diffuser as claimed in claim 1, wherein the liquid supply module further comprises: a liquid dispensing rod, which is a hollow structure having a closed tip and an open end, the open end being connected to the first connecting portion, and a plurality of liquid passage holes being formed between the closed tip and the open end; a sealing ring surrounding the periphery of the liquid dispensing rod portion and being connected to the first connecting portion; and a liquid storage box, which is pluggably and sealingly connected to the sealing ring for storing and supplying a fragrance aqueous solution, the fragrance aqueous solution flowing into the liquid storage tank through the liquid passage holes.

3. The portable fragrance diffuser as claimed in claim 1, wherein the power control circuit further comprises: a USB-C socket, partially exposed in the protective housing, for electrical connection to a USB-C plug at a power source or load; two power supply plates, installed within the second connection portion; a switch; and a power management module, electrically connected to the power module, the USB-C socket, the switch, and the power supply plates, performing the following operations: A) when the switch is on, transmitting power from the power module through the power supply plates, and when the switch is off, stopping the transmission of power from the power module through the power supply plates; and B) when it is determined that the voltage of the USB-C plug electrically connected to the USB-C socket is greater than the voltage of the power module, storing power from the USB-C socket in the power module.

4. The portable fragrance diffuser as claimed in claim 3, wherein the power management module further performs operation C): when it is determined that the voltage of the USB-C plug electrically connected to the USB-C socket is less than the voltage of the power module, the power module transmits power to the USB-C socket.

5. The portable fragrance diffuser as claimed in claim 3, wherein the atomizing module further comprises: a base having two power contact rods thereunder, each power contact rod being electrically connected to a corresponding power supply plate to obtain power; a high-frequency oscillator having its bottom electrically connected to the two power contact rods and its interior contacting the liquid guide strip to generate high-frequency oscillation to atomize the fragrance aqueous solution in the liquid guide strip; and a top cover connected to the base for guiding the atomized fragrance aqueous solution to diffuse outward.

6. The portable fragrance diffuser as claimed in claim 1, wherein the liquid guide strip is made of cotton, sponge, foam, or filter paper.

7. The portable fragrance diffuser as claimed in claim 1, wherein the protective housing forms curved surfaces with small curvature on both sides, so that the portable fragrance diffuser can be stable and not wobble when the portable fragrance diffuser contacts the placement surface with the curved surface.

8. The portable fragrance diffuser as claimed in claim 1, wherein the power module is a secondary battery module.

9. The portable fragrance diffuser as claimed in claim 1, wherein the first connecting portion further includes a plurality of plug rods, and the protective cover further forms a plurality of plug slots, each plug rod being pluggably connected to a corresponding plug slot, thereby the protective cover being indirectly connected to the protective housing.
