Foam output device easy to produce foam
First Claim
1. A foam output device easy to produce foam, comprising:
- a nozzle seat on which a joint part is formed, an assembly part being extended upwardly from said joint part;
a partition plate provided within said assembly part to separate the same into an upper chamber and a lower chamber;
a sleeve provided at the center of said partition plate;
an air vent provided on said partition plate and a one-way air intake valve provided below said partition plate, said one-way air intake valve having a through hole for engagement with said sleeve;
a planar shape elastic diaphragm formed on a peripheral wall of said one-way air intake valve, said elastic diaphragm being abutted parallelly against a bottom edge of said lower chamber;
a plurality of holding pieces having flat and straight shape formed and positioned in mutually spaced manner to encircle and securely hold a straw, said holding pieces extend from the bottom of said one-way air intake valve and with gaps formed between said holding pieces for communicating with a filter housed within a housing aperture of said sleeve;
a plurality of perforations provided on an upper edge of said sleeve to communicate with a foam buffer zone provided within a nozzle mounted over said nozzle seat, said nozzle having a nozzle outlet to communicate with said foam buffer zone.

Abstract
A foam output device easy to produce foam is composed of a nozzle seat, a one-way air intake valve, a nozzle and a filter. When conducting assembly, the filter is firstly set into the housing aperture of the nozzle seat. In turn, an through hole of the one-way air intake valve is engaged with sleeve of the nozzle seat, then the nozzle is assembled on the nozzle seat in such a manner that a clamping pieces of the nozzle clamp the coupling tabs on the nozzle seat, and that a hook on the clamping piece is in hooking engagement with a hook on the coupling tabs so as to fix together. The assembly of the present invention is thus completed in simple manner. In this way, a foam output device having simple element constitution, easy assembly and low manufacturing cost is thus provided.
