Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to the technical field of air purification and aroma diffuser, in particular an improved structure of an airflow pump aroma diffuser.

The Prior Arts

In recent years, the medicalized beauty industries have developed rapidly, and people have paid more and more attention to beauty care and medical health care. The industry has actively developed and designed various aroma diffuser structures, which are used to atomize plant aromatic liquids so that the human body can easily inhale them for aromatherapy.

A common aroma diffuser is known to mainly comprises a base with an air supply motor pump inside. A diffuser bottle is connected to the base, and a special air blowing nozzle and its corresponding straw are provided in the bottle. When the motor pump is started to supply air, the essential oil can be sucked up and atomized by siphoning, so that the aroma of the essential oil can spread quickly and evenly in the air. It lasts for a long time that is very popular among aromatherapy practitioners.

However, most of the known diffusers have an open outlet at the top of the diffuser bottle. Although the atomized aroma can be discharged directly, the structural design is not perfect. In case of accidental collision and overturning, essential oil leakage may occur and the overall shockproof and airtight sound insulation effect is poor. It is easy to vibrate, make noise and disturb the peace of life when used. In addition, the size of the fragrance mist particles released is different when it is used, which often makes the ground near the main frame wet and easily attracts dirt, causing trouble in cleaning.

More advanced improved designs, such as U.S. Pat. No. 7,878,418B2, provide an integrated essential oil atomizer that discloses an injector and a detachable atomizer that is directly connected to the storage and the supporting surface of the pump.

U.S. Pat. No. 7,930,068B2 provides a system and method for controlling the operation of a liquid expansion device. It has been disclosed that an ink cartridge holding liquid is located in a liquid diffuser.

US 20190105615A1 provides an air treatment system is provided which includes an appliance and a replaceable cartridge installable therein. The replaceable cartridge contains a liquid compound to be aerosolized and has a cartridge outlet through which the aerosolized compound is discharged during operation. A pump is provided to supply air to the replaceable cartridge to generate the aerosolized compound from the liquid compound contained in the replaceable cartridge, and a controller is provided for controlling the pump to supply the air to the replaceable cartridge to generate and discharge the aerosolized compound from the appliance. The appliance may further include a lift mechanism to assist in receiving the cartridge and moving the cartridge from a loading position to an operational position.

U.S. Pat. No. 10,507,258B2, U.S. Pat. No. 11,541,143B2, and U.S. Pat. No. 11,666,678B2, these three applications are simple integrated designs based on the same concept of the foregoing patent applications. By integrating the entire diffuser into the form of a threaded cap, the bottle becomes more compact and suitable for operation as a liquid reservoir. The motor and pump system are integrated into a package that fits within the housing, and the entire reservoir and diffuser system is then accommodated in a silo next to the pump and motor.

However, the structural designs of U.S. Pat. No. 10,507,258 B2, U.S. Pat. No. 11,541,143 B2, and U.S. Pat. No. 11,666,678B2 are still not perfect, and their overall components are too many and too complex. Especially as shown in FIG. 3, parts 42, 66, 72a, 72b, and 60 are not conducive to mold manufacturing and assembled with production. Moreover, as shown in FIGS. 1 and 5, the diffuser 12 and the reservoir 14 are installed in the base 16 during application.

Due to the lack of good docking design, the overall combination cannot be completely flat placement, and there will be obvious section protrudes above the diffuser 12, which limits the appearance of the product and prevents it from being truly flat and beautiful.
