[0027] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] Example 1: See Figures 1 to 3 In this embodiment, the filter layer of the first filter element is composed of PP cotton, granular activated carbon, carbon fiber, and other purification materials. The first filter element includes a first housing, the outer wall of the first housing is provided with a columnar filter cotton layer, the filter cotton layer can be composed of PP cotton, granular activated carbon, carbon fiber, and other purification materials. The first accommodating cavity is provided with a third through hole, and the inner wall on one side is provided with a columnar groove. The outer wall of the first housing away from the filter cotton layer is provided with a columnar protrusion that can be inserted into the columnar groove. The outer wall of the columnar protrusion is provided with a rubber ring that can increase friction. The outer wall of the columnar protrusion is provided with a first water pipe connected to the filter cotton layer, and the first water pipe is connected to the third through hole away from the columnar protrusion.

[0029] The second filter element is a columnar tank, and is provided with beneficial trace elements such as vitamin C, aromatherapy essential oils, hyaluronic acid, and minerals. The second filter element is provided with a second water pipe for water to flow from the third accommodating chamber to the sixth through hole, and one end of the second water pipe is connected to the outer wall of the second filter element in the third accommodating chamber, and one end of the second water pipe away from the third accommodating chamber is connected to the outer wall of the second filter element in the sixth through hole. When water flows from the third accommodating chamber through the second water pipe and into the sixth through hole, the trace elements in the second filter element will flow out with the water. The use of sustained-release technology allows these beneficial ingredients to be present in the water, which has the effects of hydrating, moisturizing, nourishing the skin, and delaying aging.

[0030] When it is necessary to open the water valve to allow water to enter the first filter element device. The user only needs to press the button on the outer wall of the housing, and the button will push the first sliding block to slide in the first accommodating chamber in the direction of the first spring, and the first spring will be squeezed. At this time, the second base located in the first accommodating chamber does not move, and the water valve connected to the second base through the first rotating shaft does not move horizontally at this time. When the first sliding block slides in the direction of the first spring, the first control unit located in the ninth groove of the first sliding block will slide in the direction of the third rotating shaft, and the pusher claw originally embedded in the outer wall of the third rotating shaft at one end between the ratchet structures will push the ratchet structure to move in the direction of the first spring, and the third rotating shaft will rotate circumferentially on the second base. At this time, the second arc-shaped guide surface is in contact with the first arc-shaped guide surface. When the third rotating shaft rotates circumferentially, the columnar protrusion on the upper end surface of the third rotating shaft will rotate circumferentially with the third rotating shaft, and the fifth gap between the two columnar protrusions will be connected to the first water outlet. When water enters the first accommodation cavity from the first water inlet of the outer wall of the housing, water will enter the first water outlet from the fifth gap. At this time, the user releases the pressed button, and the first sliding block will slide in the direction away from the third rotating shaft under the push of the first spring. The second arc-shaped guide surface of the pusher claw will slide along the first guide arc surface of the outer wall of the ratchet structure toward the tenth groove between each ratchet structure until the end of the pusher claw away from one end of the columnar rotating block is embedded in the tenth groove. Since a second spring is provided between the left side of the seventh limiting protrusion and the left inner wall of the ninth groove, when the pusher claw slides to the tenth groove, the second spring will push the seventh limiting protrusion to slide to the right side of the columnar rotating block, and the relative pusher claw will rotate in the opposite direction with the rotation of the seventh limiting protrusion, that is, at this time, the pusher claw will be tightly embedded in the tenth groove. At this time, after water enters the water valve from the first water inlet, it directly passes through the first water outlet and flows through the first pipeline into the cavity between the first base and the first filter cartridge housing, and the water in the cavity will immediately enter the first filter cartridge housing through the first through hole.

[0031] When the water valve needs to be closed so that water cannot enter the first filter element device. The user only needs to press the button on the outer wall of the shell again, and the button will push the first sliding block to slide in the first accommodating chamber in the direction of the first spring, and the first spring will be squeezed. At this time, the second base located in the first accommodating chamber does not move, and the water valve connected to the second base by the first rotating shaft does not move laterally at this time. When the first sliding block slides in the direction of the first spring, the first control unit located in the ninth groove of the first sliding block will slide in the direction of the third rotating shaft, and the pawl originally embedded in the outer wall of the third rotating shaft at one end between the ratchet structures will push the ratchet structure to move in the direction of the first spring, and the third rotating shaft will rotate circumferentially on the second base. At this time, the second arc-shaped guide surface is in contact with the first arc-shaped guide surface. When the third rotating shaft rotates circumferentially, the columnar protrusion on the upper end face of the third rotating shaft will rotate circumferentially with the third rotating shaft, and the columnar protrusion will rotate again to the position where the fifth gap was previously located. At this time, the first water outlet abuts against the outer wall of the columnar protrusion, and the columnar protrusion completes the closing of the first water outlet. When water enters the first accommodating chamber from the first water inlet on the outer wall of the shell, water cannot enter the first water outlet and the second water outlet from the fifth gap. At this time, the user releases the pressed button, and the first sliding block will slide in the direction away from the third rotating shaft under the push of the first spring. The second arc-shaped guide surface of the pusher claw will slide against the first guide arc surface of the outer wall of the ratchet structure toward the tenth groove between each ratchet structure until the end of the pusher claw away from one end of the columnar rotating block is embedded in the tenth groove. Since a second spring is arranged between the left side of the seventh limiting protrusion and the left inner wall of the ninth groove, when the pusher claw slides to the tenth groove, the second spring will push the seventh limiting protrusion to slide to the right side of the columnar rotating block, and the relative pusher claw will rotate in the opposite direction with the rotation of the seventh limiting protrusion, that is, at this time, the pusher claw will be tightly embedded in the tenth groove.

[0032] If the user needs to open the second water outlet through the water valve to allow water to enter the second filter device. The user only needs to press the button on the outer wall of the housing, and the button will push the first sliding block to slide in the first accommodating chamber in the direction of the first spring, and the first spring will be squeezed. At this time, the second base located in the first accommodating chamber does not move, and the water valve connected to the second base through the first rotating shaft does not move horizontally at this time. When the first sliding block slides in the direction of the first spring, the first control unit located in the ninth groove of the first sliding block will slide in the direction of the third rotating shaft, and the pusher claw originally embedded in the outer wall of the third rotating shaft at one end between the ratchet structures will push the ratchet structure to move in the direction of the first spring, and the third rotating shaft will rotate circumferentially on the second base. At this time, the second arc-shaped guide surface is in contact with the first arc-shaped guide surface. When the third rotating shaft rotates circumferentially, the columnar protrusion on the upper end surface of the third rotating shaft will rotate circumferentially with the third rotating shaft, and the fifth gap between the two columnar protrusions will be connected to the second water outlet. When water enters the first accommodating chamber from the first water inlet of the outer wall of the housing, water will enter the second water outlet from the fifth gap. At this time, the user releases the pressed button, and the first sliding block will slide in the direction away from the third rotating shaft under the push of the first spring. The second arc-shaped guide surface of the pusher claw will slide along the first guide arc surface of the outer wall of the ratchet structure toward the tenth groove between each ratchet structure until the end of the pusher claw away from one end of the columnar rotating block is embedded in the tenth groove. Since a second spring is provided between the left side of the seventh limiting protrusion and the left inner wall of the ninth groove, when the pusher claw slides to the tenth groove, the second spring will push the seventh limiting protrusion to slide to the right side of the columnar rotating block, and the relative pusher claw will rotate in the opposite direction with the rotation of the seventh limiting protrusion, that is, at this time, the pusher claw will be tightly embedded in the tenth groove. At this time, after water enters the water valve from the first water inlet, it directly passes through the second water outlet and flows through the third pipe into the cavity between the third base and the second filter cartridge housing, and the water in the cavity will immediately enter the second filter cartridge housing through the fourth through hole.
