As shown in
FIG. 2, tank
102 includes an open end
202 and a closed end
204, and an interior surface of closed end
202 establishes a bottom surface
206 of tank
102. In one aspect, base
104 is be dimensioned to receive and support closed end
204. For example,, base
104 includes a support lip
208, which may engage a circumferential portion of closed end
204, and closed end
204 may be affixed to lip
208, and to base
104, by an appropriate mechanical fastener or adhesive (e.g., a glue or a resin epoxy). In some aspects, filter base
108 is dimensioned to be removably positioned over bottom surface
206, and includes the housing support structure, e.g., housing support structure
210 of
FIG. 2, which engages and is received into a proximal end
212 of filter housing
110. Further, and as described below, housing support structure
210 includes an opening
210A that facilitates fluid communication between an interior of filter housing
110 and tank
102, e.g., through inlets
109 in filter base
108. In some aspects, filter housing
110 is dimensioned to removably receive the mechanical pump (e.g., pump
216 of
FIG. 2, which is connected to an external power source by electrical connector
112), the elongated tube (e.g., tube
218 of
FIG. 2), the reservoir (e.g., reservoir
220 of
FIG. 2), and the filter cartridge (e.g., filter cartridge
222 of
FIG. 2). Additionally, as shown in
FIG. 2, filter housing
110 includes a distal surface
214A disposed at a distal end
214 and oriented perpendicular to an axis of tank
102. In certain aspects, described in greater detail below, distal surface
214A may be dimensioned to engage with and support an outlet of reservoir
220 when reservoir
220 is removably positioned within the filter housing.
