A filter assembly includes an inner filter basket comprising an elongated tubular portion having a first open end and a first closed end. The tubular portion defines a plurality of perforations therethrough. An outer surface of the tubular portion is seamless. A first annular brim extends outwardly from the open end of the tubular portion. The filter assembly also includes an outer filter basket having a second open end in which the inner filter basket is received. A second annular brim extends outwardly from the second open end of the outer filter basket. The first and second brims are configured to retain a fabric filter bag between the inner filter basket and the outer filter basket.

The present invention pertains in general to an apparatus and method for the drying and activating of infusing material, and the infusing, agitation and dispensation of oils in a controlled manner to produce a desired potency of an infusion while remaining below an identified maximum temperature threshold.

Examples are disclosed herein that relate to an in-pond water quality maintenance system. One example provides a pond water quality maintenance system, including a skimmer basin configured to collect pond surface debris, the skimmer basin including an upper opening configured to permit a flow of water and debris from a pond surface into the skimmer basin, a strainer basket positioned within the skimmer basin and configured to trap at least some of the debris that enters the skimmer basin through the upper opening, a skimmer pump positioned within the skimmer basin below the strainer basket, the skimmer pump configured to draw water through the strainer basket and to pump the water out of the skimmer basin, and one or more lower openings configured to permit a flow of water into the skimmer basin from a pond depth below the strainer basket.

The present invention provides a structure for assembling and disassembling a dirt suction head to/from a filter bag, comprising a first connection piece and a second connection piece; one end of the second connection piece is detachably connected to a connection pipe of the dirt suction head, and the other end of the second connection piece is provided with a holding cavity; one end of the first connection piece is connected to an opening of an end of a filter bag body, and the other end of the first connection piece is assembled into the holding cavity; or a circumferential side edge of the opening of the filter bag body is tightly pressed and fixed between an outer side wall of the first connection piece and an inner side wall of the holding cavity, which has achieved a quick assembling and disassembling and smooth external aesthetics of a connection position.

A planting structure includes a water filtering bag, a plurality of hanging ears mounted on an outer face of the water filtering bag, and a plurality of planting sources placed in the water filtering bag. The water filtering bag is made of permeable material with a permeation effect. The water filtering bag has an interior provided with a receiving space. The planting sources are received in the receiving space of the water filtering bag. Thus, the planting structure is directly hung on a cup by the hanging ears, so that the user plants and takes out the planting sources at any time according to the practical requirement.

A filter bag assembly includes a flexible bag bounding a compartment that is configured to hold a fluid. An inlet port and an outlet port are each secured to the flexible bag so as to communicate with the compartment. A porous filter sheet is disposed within the compartment of the flexible bag so that fluid entering the compartment through the inlet port must pass through the filter sheet before exiting the compartment through the outlet port. A first retention seal secures the porous filter sheet to a portion of the flexible bag within the compartment, the first retention seal having an outer perimeter edge that forms an annular continuous loop.
