## Abstract

A liquid spray device includes a container defining a reception space for receiving a liquid medicine therein, having a discharge outlet for discharging the liquid medicine to an exterior of the container; a spray module disposed in the discharge outlet, and connected electrically to a driving source such that the liquid medicine forcefully collides against the discharge outlet due to ultrasonic oscillation of the spray module and spraying out a plurality of mist droplets; and a particle sorter disposed downstream to a discharging direction of the liquid medicine, spaced from the spray module at a predetermined distance to permit once against collision of the liquid medicine during the discharging operation such that the mist droplets are sprayed out through the particle sorter in terms of a plurality of micro-mist droplets along the discharging direction.

## Claims

### Claim 1

A liquid spray device, comprising:
a container defining a reception space for receiving a liquid medicine therein, said container having a discharge outlet for discharging the liquid medicine to an exterior of the container, said container further having a first opening formed at a bottommost portion thereof and a second opening formed at a topmost portion thereof and in spatial communication with said reception space;
a spray module disposed in said discharge outlet, and being connected electrically to a driving source such that the liquid medicine forcefully collides against said discharge outlet due to ultrasonic oscillation of said spray module, thereby spraying out a plurality of mist droplets;
a particle sorter disposed downstream to a discharging direction of the liquid medicine, spaced from said spray module at a predetermined distance to permit further collision of the liquid medicine during a discharging operation such that said plurality of mist droplets are sprayed out through the particle sorter in terms of a plurality of micro-mist droplets along the discharging direction; and
a recycle system that is installed within said container, that is adapted to collect said plurality of mist droplets and that is adapted to automatically transfer said plurality of mist droplets back into said liquid medicine for collecting in said reception space in said container, said recycle system including a collection tube fastened to said container and having a lowest tube section proximate to and in spatial communication with said first opening, and a connection pipe interconnecting said first and second openings such that in case said discharge outlet is biased by pressure of the liquid medicine during the discharging operation, a siphon phenomenon is resulted due to vacuum of said reception space to draw said plurality of mist droplets collected at said lowest tube section back into said reception space via said first opening, said connection pipe and said second opening.

### Claim 2 (depends on 1)

The liquid spray device according to claim 1, wherein said collection tube has a dispensing tube section inclined upward with respect to an axis of said discharge outlet of said container.

### Claim 3 (depends on 1)

The liquid spray device according to claim 1, wherein said particle sorter is planar, concave or convex with respect to said spray module.

### Claim 4 (depends on 3)

The liquid spray device according to claim 3, wherein said particle sorter has a surface area greater than that of said spray module.

### Claim 5 (depends on 3)

The liquid spray device according to claim 3, wherein said particle sorter has a surface area smaller than that of said spray module.

### Claim 6 (depends on 3)

The liquid spray device according to claim 3, wherein said particle sorter has an interior surface facing said spray module and formed with a plurality of recesses.

### Claim 7 (depends on 3)

The liquid spray device according to claim 3, wherein said particle sorter has an interior surface facing said spray module and formed with a plurality of protrusions.

### Claim 8 (depends on 3)

The liquid spray device according to claim 3, wherein said predetermined distance is greater than a diameter of said particle sorter.

### Claim 9 (depends on 3)

The liquid spray device according to claim 3, wherein said predetermined distance is smaller than a diameter of said particle sorter.
