Atomizer

1. Field of the Invention

This invention relates to an atomizer.

2. Description of the Related Art

As shown in FIGS. 1 and 2, a conventional atomizer includes a container 1 having a jet nozzle 101 defining an air passage 102 therein; a jacket 2 sleeved around the jet nozzle 101 of the container 1 so as to define a gap 201 therebetween, and having an opening 202 in fluid communication with the air passage 102, and a jet-blocking plate 203 disposed above the opening 202; and a cap 3 having a mist path 302 defined by a peripheral wall 301 and a blocking wall 303 connected to the peripheral wall 301. During assembling, the jacket 2 is sleeved around the jet nozzle 101 of the container 1, and the cap 3 is secured to the container 1 so that the blocking wall 303 of the cap 3 abuts against the jet-blocking plate 203 of the jacket 2. In use, when high-pressure air (50 psi) flows through the air passage 102, a fluid contained in the container 1 will flow through the gap 201 between the jacket 2 and the jet nozzle 101 because of a negative pressure generated in the air passage 102. The fluid flowing through the gap 201 will be atomized by the high-pressure air. The mist thus formed flows into the mist path 302 through the opening 202.

Although the conventional atomizer can achieve an atomizing function, there are certain drawbacks in practice.

Since the jet nozzle 101, the jacket 2, and the cap 3 are separate parts, a high precision is required to manufacture these parts so as to ensure appropriate abutment between the blocking wall 303 of the cap 3 and the jet-blocking plate 203 of the jacket 2, and so as to prevent relative movement between the jacket 2 and the jet nozzle 101, which can result in a poor atomizing effect.

In addition, since the container 1, the jacket 2, and the cap 3 are three individual parts, costs for manufacturing the atomizer are increased, and the manufacturing process is relatively complicated. Moreover, since the jacket 2 is relatively small in size, it is likely to be misplaced.

Therefore, the object of the present invention is to provide an atomizer that can overcome the aforesaid drawbacks of the prior art.

According to this invention, an atomizer includes an enclosed reservoir defining an inner space adapted to receive a liquid therein, a jet nozzle provided in the inner space for passage of an air jet therethrough, a jacket sleeved around the jet nozzle to define a fluid-introducing gap therebetween, the fluid-introducing gap being in fluid communication with the inner space for passage of the liquid therethrough, a mist-discharging conduit extending sealingly into and in fluid communication with the inner space for passage of a mist therethrough and aligned with the jacket in a jet-ejecting direction, and a compressible member connected to the mist-discharging conduit and the jacket and compressible in the jet-ejecting direction so as to retain the jacket at a predetermined position. The jacket, the compressible member, and the mist-discharging conduit are an integrally formed single piece.
