Disclosed herein is a filter mounting structure of a vacuum cleaner.

The precision filter is provided with an air diaphragm (12), a selective infusion device and a filter mounting base (8).

The selective infusion device is fixed on the filter mounting base (8).

The air diaphragm (12) is arranged at the bottom end of the filter mounting base (8) or at the bottom of the portion of drip chamber (1) arranged under the filter mounting base.

The present invention relates to a water-filter mounting structure for a refrigerator.

The filter mounting structure allows the filter to be inserted into or separated from the discharge port without dissembling the main body of the vacuum cleaner, thereby allowing easy cleaning and replacement of the filter.

Also disclosed herein are the filter mounting plate (15) itself, with and without the removable filter element (s) (16).

An interior-air filter (26) for collecting dust in the air is provided at the filter mounting opening (25) of the interior-air introduction duct (23).

Internal nose filter mounting devices, methods and kits are provided.

The configurable fluid filter bracket includes a body, two or more selectively connectable ports provided on the body, and a filter mounting boss.

A new lens filter adapter FA-DC58B attaches directly to the lens barrel ring, providing the ability to attach 58mm diameter Canon filters – such as a Circular Polarizer, Neutral Density, Protect and UV.

The liquid inlet end surface of the continuous liquid supply orifice (11) is positioned at the bottom of the filter mounting base (8).

A housing for mounting HEPA filters includes an open-ended tubular casing (12) and, within said casing, slide structure (24) for slidably mounting a HEPA filter therein from one of the ends of the casing.

An optical filter mount and adapter is provided for use with a camera and an underwater camera housing.

Its threaded front allows for mounting of 49mm filters such as the Canon 49mm Protect Filter
