A filter element mounting structure comprises a switch member arranged on a shell, a limiting member and a driving mechanism; the driving mechanism is arranged on the shell, the limiting member is connected with the driving mechanism, a locking groove is formed on a filter element, the limiting member comprises a plurality of locking positions comprising a first locking position, a second locking position and a third locking position; when the limiting member is in the first locking position, the filter element is mounted in the shell, when the filter element is mounted in the shell, the switch member is touched, and the driving mechanism controls the limiting member to move to the second locking position and lock the filter element; and when the driving mechanism drives the limiting member to move to the third locking position, the limiting member provides an ejecting force to eject the filter element.

A purification device comprises a main body having an open extending horizontally; a rotator in the opening to be rotatably mounted on the main body; and a manipulation structure spaced from and above the rotator and rotatably connected to a top face of the main body, the manipulation structure protruding forward of the main body. The device also includes a water-outlet module with a fixed cover fixed to the rotator through the opening, the fixed cover protruding forward of the main body, and a top of the fixed cover being connected to a bottom of the manipulation structure; a vertically-movable cover held in contact with the fixed cover; and a water-outlet nozzle mounted onto a bottom of the vertically-movable cover. When the vertically-movable cover rises to a highest level, a top of the vertically-movable cover is located in a space between the rotator and the manipulation structure.

A fuel filter for an internal combustion engine may include a filter housing, a ring filter element arranged in the filter housing, a function carrier engaging in an interior space of the ring filter element, a water collection space arranged below the ring filter element, a first venting part channel, and a second venting part channel. The function carrier may include a clean channel extending therein. The first venting part channel may extend from the water collection space through the function carrier and may be communicatingly connected to an air discharge channel extending in the function carrier. The second venting part channel may extend through an upper end disc of the ring filter element and may be communicatingly connected to the air discharge channel.

A fuel filter for an internal combustion engine may include a filter housing, a filter housing cover detachably connected to the filter housing, a filter space delimited by the filter housing cover and the filter housing, and a ring filter element arranged in the filter space. The filter housing cover may include a head portion and a foot portion. The filter housing cover may have at least one foot inner diameter and at least one head inner diameter that extend transversely to an axial direction. The ring filter element may have at least one outer diameter that corresponds to the at least one foot inner diameter. The at least one head inner diameter may be smaller than the at least one foot inner diameter. The ring filter element may form a venting device, which may form at least one venting channel that leads into the head portion.

A water purifying filter has a cylindrical inner housing to receive a filter therein, and an outer housing to receive the inner housing. The inner housing and the outer housing are spaced apart from each other to form an insulation space configured to suppress heat transfer and to reduce the filter freezing inside the inner housing.

This disclosure relates generally to a filter media that can be used to filter a spa, hot tub, or pool. The filter media can include a body with a top surface, a bottom surface, and a plurality of pleats. A border is joined and surrounding a periphery of the body, the border for maintaining a planar shape of one or more of the top surface and bottom surface of the filter media.

A filter device may include a plurality of sections including one or more panels formed from one or more air filter media and one or more hinges arranged between two or more sections of the plurality of sections. The filter device may be disposed within a space and may be retrieved from the space via a direct access opening within a cooling system. When the filter device is disposed within the space, the filter device may be arranged parallel to a coil. When the filter device is retrieved from the space, a first section of the filter device may bend via a first hinge of the one or more hinges to retrieve the first section from the space via the direct access opening of the cooling system.

The water purifier according to an aspect of the present invention may include a housing; a first module unit configured to generate purified water or ice; a second module unit connected to the first module unit to discharge purified water or ice to the outside; and a front panel unit having a size and shape capable of covering the opening of the housing and coupled to the housing to be opened and closed through linear or rotational motion to conceal the opening in a closed state and to expose the opening in an open state.
