[0032] The filter device of the above structure can control whether the water entering from the input pipe 110 is output from the output pipe 120 after passing through the corresponding filter core 10, when the water needs to pass through the filter core 10, the connecting seat 200 moves relative to the head body 100 to make the input pipe 110 connect the first water inlet pipe 210, the water enters from the first water inlet pipe 210 and passes through the filter core 10 and is discharged from the pure water pipe 12, and the water discharged from the pure water pipe 12 is sequentially output through the outlet tube 230 and the output pipe 120; when the water does not need to pass through the filter core 10, the connecting seat 200 moves relative to the head body 100 to make the input pipe 110 connect the second water inlet pipe 220, the water directly returns to the outlet tube 230 from the bypass waterway 240, and does not pass through the filter core 10; so that the water can be selected to pass through the corresponding filter core 10 or be directly conveyed, so that different filtered water can be produced by cooperating with other filter devices.

[0033] Referring to Figure 3 And Figure 4In some embodiments of the present invention, a first one-way valve 300 is provided in the water outlet pipe 230 or the pure water pipe 12 of the filter element 10 to prevent the water in the bypass waterway 240 from flowing into the filter element 10. It is understandable that since the water outlet pipe 230 and the pure water pipe 12 of the filter element 10 are in a connected state, when water passes through the second water inlet pipe 220 and the bypass waterway 240 and then enters the water outlet pipe 230, some water is likely to flow back into the filter element 10, affecting the service life of the filter element 10. The provision of the first one-way valve 300 can ensure that water is directly discharged from the water outlet pipe 230, preventing water from passing through the filter element 10.

[0034] See also Figure 3 In some embodiments of the present invention, a second one-way valve 400 is provided between the first water inlet pipe 210 and the input pipe 110, and both the second one-way valve 400 and the first one-way valve 300 are provided on the connecting base 200. It is understood that the provision of the second one-way valve 400 can prevent water from flowing back toward the input pipe 110. The provision of both the second one-way valve 400 and the first one-way valve 300 on the connecting base 200 facilitates the adaptation of a common filter element 10 and improves the flexibility of product use.

It will be appreciated that when the connecting base 200 is rotated relative to the handpiece body 100 about the axis of the output pipe 120, the inlet pipe 110 can be directly opposite the first water inlet pipe 210 or the second water inlet pipe 220, while the water outlet pipe 230 can remain connected to the output pipe 120, thereby enabling water to pass through the filter element 10 or not, thereby facilitating operation and use. Of course, in other embodiments, the water outlet pipe 230 is connected to the output pipe 120 through a hose, and the connecting seat 200 is translated relative to the head body 100 to enable the input pipe 110 to connect to the first water inlet pipe 210 or the second water inlet pipe 220, which can also achieve the corresponding function.

It can be understood that there is a gap between the upper end surface of connecting seat 200 and upper mounting seat 102, which cannot achieve the effect of complete sealing, therefore, when input pipe 110 communicates with first water inlet pipe 210, water is easy to overflow from the junction between input pipe 110 and first water inlet pipe 210 to second water inlet pipe 220, thereby affecting the normal working of the function of the filter device switching waterway of the utility model, and first sealing member 500 can realize the sealing between input pipe 110 and first water inlet pipe 210 and the sealing between input pipe 110 and second water inlet pipe 220.

It can be understood that, since the first sealing ring 510 is arranged around the input pipe 110, when the connecting seat 200 is rotated to align the first water inlet pipe 210 or the second water inlet pipe 220 with the input pipe 110, a sealing effect can be achieved, and the second sealing ring 520 can further isolate the first water inlet pipe 210 and the second water inlet pipe 220 when the filter element 10 is used to filter water. In addition, it should be noted that the first sealing ring 510 and the second sealing ring 520 elastically abutted to the connecting seat 200 play a role of friction damping, that is, the connecting seat 200 is stabilized after being rotated by a certain angle relative to the head body 100, and the light touch connecting seat 200 is prevented from being easily rotated relatively.

[0039] Referring to Figures 2 to 6 In some embodiments of the utility model, the mounting surface 105 and the upper end surface of the connecting seat 200 are further provided with the third sealing ring 600, the third sealing ring 600 and the first sealing ring 510 are symmetrically distributed about the center of the connecting seat 200, and the third sealing ring 600 is elastically abutted to the upper end surface of the connecting seat 200 to prevent the connecting seat 200 from tilting relative to the head body 100. It should be noted that, when the first sealing ring 510 is clamped between the connecting seat 200 and the upper mounting seat 102 to form a certain height gap, the third sealing ring 600 can be supported between the connecting seat 200 and the upper mounting seat 102, preventing the phenomenon of tilting caused by one-sided protrusion.
