Referring to fig. 1 to 5, a shower 100 is provided. The shower 100 includes the filter cartridge assembly 10 and the waterway switching assembly 110 of any of the above embodiments. Referring to fig. 6 to 9, the waterway switching assembly 110 includes a main body 111 and a switching valve 118.

The body 111 includes a cartridge mount 1111. The cartridge assembly 10 is removably mounted to the cartridge mount 1111, and the filtered water pathway 1114 passes through the cartridge assembly 10, the cartridge mount 1111 including the guide structure 11111 and being formed with the mounting slot 11112. Upon mounting the cartridge assembly 10 to the cartridge mount 1111, the connector 16 can snap into and connect with the mounting slot 11112 such that the cartridge assembly 10 is stably mounted to the cartridge mount 1111.

The main body 111 is formed with a water supply waterway 1112, a main water outlet waterway 1113, and a filtered water outlet waterway 1114. The water supply waterway 1112 is communicated with the water inlet 101, and the main water outlet waterway 1113 and the filtered water outlet waterway 1114 are both communicated with the water outlet 102. The water in water supply waterway 1112 is water that is output after the water temperature is adjusted to a preset temperature by a user through cold and hot water. The body 110 has a transverse channel shape.

The switching valve 118 selectively switches the water supply path 1112 to communicate with the main water outlet path 1113 or the filtered water outlet path 1114. Specifically, referring to fig. 1, water at a predetermined temperature flows into the filter element assembly 10 through the water supply path 1112. Switching valve 118 is connected to main body 111 and is provided at one end opposite to water supply path 1112.

As such, the user can switch the switching valve 118 of the assembly 110 through the waterway, thereby changing the waterway flow direction through the switching valve 118, and further making the water supply waterway 1112 to communicate with the main water outlet waterway 113, thereby outputting the general water not passing through the filter element assembly 10, or the water supply waterway 1112 to communicate with the filter water outlet waterway 1114, thereby outputting the functional water passing through the filter element assembly 10.

It is to be understood that the one-way valve 120 means that water can only pass through the valve in one direction, but water in the opposite direction cannot pass through the valve. Thus, functional water filtered by the filter element assembly 10 can flow out through the check valve 120, and ordinary water cannot flow in from the check valve 120, that is, the setting of the check valve 120 can ensure that ordinary water output by the main water outlet water passage 1113 cannot flow in the filter element assembly 10 through the check valve 120. Therefore, due to the one-way valve 120, when the waterway control device 100 needs to output normal water, the normal water does not flow into the filter element assembly 10 for filtering, so that the service life of the filter element 121 disposed in the filter material housing 12 can be prolonged.

Considering from another aspect, the check valve 120 can only output the functional water outputted through the filter cartridge module 10, and can ensure the purity of the outputted functional water and precisely control the purity of the outputted mixed water.

Referring to fig. 4 or 5, a second sealing member 134 is also disposed at a connection end of the outer peripheral wall 132 of the water diversion conversion piece 13 and the check valve 120, so that the filtered water flowing out of the filter element water inlet channel 133 is not easy to flow out of a gap between the water diversion conversion piece 13 and another structural member, and the filtered water can completely enter the check valve 120, thereby achieving a good sealing effect. The second sealing element 134 may be a silicone ring, a rubber ring, or a component made of other materials, which is not limited herein.

The filter cartridge assembly 10 is positioned above the main body 111, and the water outlet 102 is positioned below the main body 111.

The length of the switching valve core 1181 is equal to the sum of the widths of the valve core pressing cap 1182 and the knob 1183, and the valve core pressing cap 1182 may be firstly matched with the switching valve core 1181, and then the valve core pressing cap 1182 is fixed in the assembly 117. Finally, knob 1183 may engage a protruding link 11812 of switch spool 1181. The knob 1183 is rotated to drive the switching valve core 1181 to rotate, so that the switching function of the waterway switching assembly 110 is realized.

Specifically, if the knob 1183 is in the normal water outlet position, the inlet water directly flows out of the main water outlet path 1113 to the water outlet 102 after passing through the switching valve core 1181. If the knob 1183 is in the functional water outlet position of the filter element 121, the inlet water flows into the filtered water path 1114 and the filter element 121 after passing through the switching valve core 1181, so that the filter material in the filter element is fully dissolved in the water, and the functional water is output to the water outlet 102.

The switching chamber 1115 includes an inlet 11151, a second outlet 11153 and a first outlet 11152. Connecting rod 11812 has a hollow channel in the center, which is inlet 11151 of water supply waterway 1112. Water entering from the inlet 11151 passes through the cavity of the switching chamber 1115 to flow to the second outlet 11153 or the first outlet 11152.

Inlet 11151 communicates with feed water channel 1112. The second outlet 11153 communicates with the filtered water path 1114. The first outlet 11152 communicates with the main effluent water path 1113. Referring to fig. 4 and 5, the switch valve core 1181 selectively blocks the second outlet 11153 or the first outlet 11152, that is, the core 11811 of the switch valve core 1181 may selectively block the second outlet 11153 or the first outlet 11152, so that water flowing out of the switch chamber 1115 may selectively enter the filter cartridge assembly 10 for filtering.

Referring to fig. 1, the cartridge assembly 10 is in communication with the filtered water pathway 1114, and the cartridge assembly 10 is removably mounted to the main body 111. In this manner, the filter element assembly 10 can be easily cleaned by a user, and the filter element assembly 10 can be quickly installed and easily removed.

Referring to fig. 7, the filter material housing 12 of the filter element assembly 10 is inserted between the water inlet 101 of the filter material housing 12 and the switching valve 118 to form a stable cross-shaped structure. As can be appreciated, the stable structure of the waterway switching assembly 110 can be further ensured, and the waterway switching assembly 110 is smaller in overall size and occupies less space, which is beneficial to the installation and arrangement of the waterway switching assembly 110 in the shower 100.

Referring to fig. 1, the water outlet direction of the water outlet 102 is the same as the water outlet direction of the filter element assembly 10, so that the functional water filtered by the filter element assembly 10 can flow directly to the water outlet 102, and the functional water filtered by the filter element assembly 10 can flow out of the water outlet 102 relatively quickly.

Referring to fig. 1, the water outlet direction of the water outlet 102 is perpendicular to the water inlet direction of the water inlet 101, so as to prevent the water flowing from the water inlet 101 from flowing to the water outlet 102 without being filtered, which may cause impure functional water filtered by the filter element assembly 10.
