USD436360S1 - Diaphragm pump - Google Patents

Description

The article to which my new design is applied, “diaphragm pump”, is used as air pump for supplying air into air mat or air bed. The advantage of this article is that is has an excellent low noise effect, because container which contains driving unit (pump body), filter holder and fluid tank are formed as one unit, and besides casing has a shape like a bathtub turned upside down, not like a bathtub in a normal position with lid as usual.

FIG. 1 is a perspective view of my new design of diaphragm pump;

FIG. 2 is a front view thereof;

FIG. 3 is a rear view thereof;

FIG. 4 is a right side view thereof;

FIG. 5 is a left side view thereof;

FIG. 6 is a plane view thereof; and,

FIG. 7 is a bottom view thereof.
