Example two

Referring to fig. 4 and 5, the present invention also provides a water purifier including a filter cartridge 500 and a bracket 600 having a sleeve 610, and a cartridge holder 620 coupled to one end of the sleeve 610. The sleeve 610 has a hollow assembly cavity 611, the filter element 500 is locked to the filter element seat 620 through the assembly cavity 611, the water purifier further includes a rod changing bar as described in the first embodiment, the bracket 600 is provided with a guide hole (not shown), and the rod changing bar can pass through the guide hole to match with the filter element seat 620, so that when an external force acts on the pressing member 300, the rod changing bar moves along the axial direction of the sleeve 610.

It should be noted that, in most of the water purifiers on the market, the arrangement of the filter element inside the water purifier is generally divided into two types, one is a mode in which the filter element is vertically arranged, and the other is a mode in which the filter element is horizontally arranged. Based on the difference of filter core setting mode, the water purifier all has the difference of different degrees to the operation mode when putting the filter core to the requirement of placing the space, user, perhaps the cheap degree of assembly etc.. If the difference between the filter element setting manners is analyzed by taking the operation manner of the user as an example, the method specifically includes:

when the filter element is vertically arranged, if a user wants to take the filter element out of the water purifier, the corresponding element changing structure needs to be touched, the filter element is lifted vertically upwards after the filter element is unlocked from the filter element seat, and then the filter element is taken to a proper position; when the filter element is transversely arranged, if a user wants to take the filter element out of the water purifier, the corresponding element replacing structure is required to be firstly triggered to unlock the filter element and the filter element seat. However, at this time, the user does not need to lift the filter element upward, but can remove the filter element by pulling in the horizontal direction, which is undoubtedly more labor-saving than the mode in which the filter element is vertically placed.

The filter core can be conveniently taken and placed by a user to a certain extent in a transverse mode, the assembly difficulty of the filter core is reduced, and the use experience of the user is optimized. Although the arrangement manner of the filter element in the water purifier provided by the present application is not specifically limited, in order to better combine aspects such as product background, design requirement, and user experience to explain the technical solution, the filter element 500 may be preferably arranged in a horizontal structure.

Further, the outer circumference of the locking ring 623 may be further provided with a shift lever 624, the shift lever 624 constituting the operation end. In order to improve smoothness and reliability of the engagement between the transmission inclined surface 211 and the operation end in the touch plate 210, for example, the outer surface of the shift lever 624 and the transmission inclined surface 211 may be provided as arc surfaces.
