A second unlocking ramp 522 may be provided on the third end. The first unlocking slant 511 is opposite to the second unlocking slant 522. The fourth end may extend in the axial direction of the filter cartridge 400 to an end of the main body 100, for example, to a second end of the inner sleeve 110.

Wherein, when the unlocking sleeve 520 is at the initial position, the rotation clamping member 510 is at the locking position. When the unlocking sleeve 520 is in the pressed position, the first unlocking ramp 511 and the second unlocking ramp 522 cooperate to place the rotation member 510 in the unlocked position. Specifically, for example, when the unlocking sleeve 520 moves downward from the initial position to the pressed position, the second unlocking inclined surface 522 pushes the first unlocking inclined surface 511 along the circumferential direction, so that the rotation member 510 rotates clockwise. Thereby, the rotation member 510 is rotated from the locking position to the unlocking position. Through the arrangement, the filter element 400 and the water passing assembly 300 are easily unlocked, and the use experience of a user is better.

In this embodiment, as shown in fig. 3-4, check valves 700 may be provided on the water inlet 411 and the water outlet 412 of the water passing assembly 300 (e.g., the filter base 320) and the filter cartridge 400. After the filter element 400 and the water passing assembly 300 are unlocked, water in the filter element and the water passing assembly cannot flow out, so that waste of water resources is reduced.

Further, as shown in fig. 1-2 and 5, a handle 420 can be provided on an end of the cartridge 400. The handle 420 is movable between a closed position and an open position. Illustratively, as shown, an end of the handle 420 may be pivotably connected to an end of the cartridge 400, and the end of the handle 420 protrudes out of the side of the cartridge 400. When the handle 420 is pivoted from the closed position shown in the figures to the open position (i.e., the handle 420 is upright), the end of the handle 420 is rotated downward, thereby urging the unlocking sleeve 520 downward to the unlocked position. That is, the unlocking sleeve 520 is in the initial position when the handle 420 is in the engaged position. When the handle 420 is in the open position, the unlocking sleeve 520 is in the depressed position. Thus, when it is desired to unlock the cartridge 400, the cartridge 400 can be removed by simply moving the handle 420 to the open position and then pulling the handle 420.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front", "rear", "upper", "lower", "left", "right", "horizontal", "vertical", "horizontal" and "top", "bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and in the case of not making a contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner" and "outer" refer to the interior and exterior relative to the contours of the components themselves.

For ease of description, relative terms of regions such as "above … …", "above … …", "above … …", "above", and the like may be used herein to describe the regional positional relationship of one or more components or features with other components or features as illustrated in the figures. It is to be understood that the relative terms of the regions are intended to encompass not only the orientation of the element as depicted in the figures, but also different orientations in use or operation. For example, if an element in the drawings is turned over in its entirety, the articles "over" or "on" other elements or features will include the articles "under" or "beneath" the other elements or features. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". Further, these components or features may also be positioned at various other angles (e.g., rotated 90 degrees or other angles), all of which are intended to be encompassed herein.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, elements, components, and/or combinations thereof, unless the context clearly indicates otherwise.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein.

The present invention has been described in terms of the above embodiments, but it is to be understood that the above embodiments are for purposes of illustration and description only and are not intended to limit the invention to the described embodiments. Furthermore, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that many more modifications and variations are possible in light of the teaching of the present invention and are within the scope of the invention as claimed.
