Description

[Detailed Description of the Invention] The present invention relates to a small atomizer, and more particularly, to a small atomizer that removes dust inherent in the atomizer near the nozzle hole above the sprayed liquid path, thereby preventing the nozzle hole from being clogged.

Conventionally, atomizers have been installed with a filter in the lower passage of the cylinder to prevent dust contained in the liquid storage container from entering the cylinder, but in general, in atomizers, dust attached to each part or parts is synthesized. When the sprayer is made of resin, it often has dust attached to it, or dust often gets into the sprayer during assembly.

In such cases, conventional atomizers are disadvantageous in that they are unable to remove dust, and therefore troubles such as nozzle holes becoming clogged or insufficient atomization often occur.

Therefore, the present invention eliminates the above-mentioned drawbacks with a simple configuration.

An embodiment of the present invention will be described below with reference to the drawings. A cylinder 2 is fitted and hung down on a holding cap 1 which can be attached and detached to the mouth and neck of a liquid storage container, and a piston 3 fitted into the cylinder 2 is provided at the bottom. The hollow slider tube 4 passes through the top of the holding cap and projects upward, and a spray button 6 with a nozzle hole 5 is removably attached to the projecting end, and the cylinder and the slider tube are connected to each other. This constitutes the pressurizing chamber A.

The slider tube 4 is elastically biased in the upward direction by a spring 7 interposed between its lower end and the bottom wall of the cylinder, and the cylinder has a suction tube 8 vertically connected to the bottom of the passage 9 at the bottom thereof. In addition, a check valve 10 is provided at the upper part of the passage 9, which opens only when liquid is sucked up. By applying pressure, the liquid is sprayed in the form of mist from the nozzle hole 5 through the liquid path a leading from the pressurizing chamber A to the nozzle hole 5, and the present invention allows the liquid to flow to the upper end of the slider tube 4 without obstructing the passage of the liquid. , and a filter 1 consisting of a net or the like with minute holes capable of removing dust.
1 is heated and sealed, and a filter is provided near the nozzle hole above the injection liquid path leading from the pressurizing chamber A to the nozzle hole 5.

When installing the filter 11, as shown in FIG. 2, a step part 12 on which the filter can be placed in advance is placed on the upper end of the synthetic resin slider tube 4, and a seal piece 13 is placed around the step part. is provided protrudingly, and the filter 1 is attached to the stepped portion 12.
1 is placed, the seal piece 13 is heated and its periphery is welded onto the stepped portion, and the filter is attached to the slider tube.

In this way, the periphery of the filter is covered with the molten resin, so even if there are fine chips attached to the periphery, they will be encapsulated in the molten resin and will not enter the liquid path. This is convenient because the dust is removed.

As described above, according to the sprayer of the present invention, the upper portion of the liquid injection path a extending from the pressurizing chamber A to the nozzle hole 5, near the nozzle hole;
In other words, a simple structure in which a filter is attached by welding to the upper end of the slider tube, which is the most convenient position for collecting the dust contained in each part of the vessel at the final stage of the injection liquid path a, allows the filter to be placed in the liquid. Most of the dust contained in the atomizer can be removed by a filter during the liquid jetting process, which may clog the nozzle hole 5 and make it impossible to spray, or the liquid may be sprayed with insufficient atomization. Such troubles can be prevented from occurring, and the atomizing operation can be maintained for a long period of time with good atomization.Also, since the filter 11 is fixed to the slider tube by heat sealing, there is almost no risk of it coming off. At the same time, it is possible to prevent chips from coming out from the periphery of the filter, so the intended purpose is fully achieved, and since the filter is exposed by removing the sprayer, cleaning etc. can be done easily. .
