US 9,308,472 B2 · Composite filter apparatus

Abstract

A composite filter apparatus includes a container with a receiving space, and top and bottom openings communicated with the receiving space. A filter member includes a filter core in the receiving space, a blocking member on a top end of the filter core, and a retainer plate on a bottom end of the filter core. The receiving space is divided by the blocking member into an upper receiving space that communicates the top opening of the container, and a lower receiving space that surrounds the filter core and that communicates the bottom opening. Activated carbon particles are filled in the upper and lower receiving spaces.

Dependent claims

A composite filter apparatus adapted for filtrating an incoming fluid, comprising:

a container including an annular body that has an inner surface surrounding a receiving space, top and bottom openings that are communicated with said receiving space, and a press-fit sleeve portion that is disposed on said inner surface in proximity to said bottom opening;
a filter member mounted inside said receiving space, said filter member including a filter core, a blocking member that is mounted on a top end of said filter core, and a retainer plate that is mounted on a bottom end of said filter core and that is positioned inside said press-fit sleeve portion, said filter core being configured as a porous tube having an axial hole, said blocking member blocking said axial hole at said top end of said filter core, said retainer plate having an annular part that is transverse to said bottom end of said filter core and a plate hole that intercommunicates with said axial hole and said bottom opening of said annular body, said receiving space being divided by said blocking member into an upper receiving space that communicates said top opening of said container, and a lower receiving space that surrounds said filter core and that communicates said bottom opening of said annular body;
and
activated carbon particles filled in said upper and lower receiving spaces;
wherein said blocking member has a plug body that is inserted into said axial hole at said top end of said filter core, an abutment ring that radially extends from said plug body and that abuts against said inner surface of said annular body, and a plurality of through holes that extend axially through said abutment ring;
and
wherein the fluid enters said top opening, consecutively passes through said activated carbon particles in said upper receiving space and in said lower receiving space to flow into said axial hole, and then flows through said plate hole and said bottom opening to exit said container.

#This application claims priority of Taiwanese Application No. 102201186, filed on Jan. 18, 2013.

#1. Field of the Invention

#The invention relates to a filter apparatus, more particularly to a composite filter apparatus for replacing filter materials in an independent manner.

Brief description of the drawings6 figures

#Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:

#FIG. 1 is a schematic sectional view of a first conventional filter apparatus disclosed in Taiwanese Patent No. 527954;

#FIG. 2 is a schematic sectional view of a second conventional filter apparatus disclosed in Chinese Patent No. ZL 200720195995.7;

Detailed description1,534 words

#Referring to FIGS. 3 to 5, the preferred embodiment of a composite filter apparatus according to the present invention is illustrated. The composite filter apparatus is adapted for filtrating an incoming fluid. In this preferred embodiment, the composite filter apparatus includes a container 4, a filter member 5 and activated carbon particles 6.

#The container 4 includes an annular body 41 that has an inner surface 410 surrounding a receiving space 42, top and bottom openings 43, 44 that are communicated with the receiving space 42, and a press-fit sleeve portion 45 that is disposed on the inner surface 410 in proximity to the bottom opening 44.

#In this preferred embodiment, the annular body 41 is in a form of a tubular shape. The container 4 further includes a top lid 412 that is disposed on a top open end of the annular body 41. The top opening 43 is formed centrally on the top lid 412. The bottom opening 44 is formed centrally in a bottom wall of the annular body 41.
