[0028] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figures 1 to 6 As shown, a faucet with a water purification function provided in this embodiment includes a faucet body 11 with a thermostatic valve 12, a cold water inlet pipe 21, a hot water inlet pipe 22, a mixing water pipe 24, a water outlet pipe 25, a solenoid valve 40 and a filter element 30. Specifically, in this embodiment, the thermostatic valve 12, the solenoid valve 40 and the filter element 30 are existing products, and their specific structures and working principles are not described in detail here. The hot water inlet pipe 22 is connected to the hot water inlet of the thermostatic valve 12, and the cold water inlet pipe 21 has a first cold water outlet 1 and a second cold water outlet 2. The first cold water outlet 1 is connected to the cold water inlet of the thermostatic valve 12. Specifically, the first cold water outlet 1 is connected to the cold water inlet of the thermostatic valve 12 through an intermediate pipe 23. The outlet of the thermostatic valve 12 is connected to the mixing water pipe 24, and the hot water and one of the cold waters enter the thermostatic valve 12 respectively, and are mixed and temperature-controlled by the thermostatic valve 12. The mixed water after temperature adjustment flows out from the mixing water pipe 24.

[0030] The second cold water outlet 2, the solenoid valve 40 and the filter element 30 are connected in sequence; the solenoid valve 40 is arranged between the second cold water outlet 2 and the filter element 30 to control the on-off of the cold water flow entering the filter element 30.

[0031] One working principle is as follows: when mixed water needs to be turned on, the thermostatic valve 12 is directly manually operated to adjust the temperature and discharge water, wherein the mixed water flows out through the mixed water pipe 24 and then directly flows out through the second water outlet 254 of the water outlet pipe 25. When purified water needs to be turned on, the thermostatic valve 12 is closed, and the water path entering the filter element 30 is opened by controlling the solenoid valve 40. The water flows through the filter element 30 and is purified to obtain purified water, which flows out from the first water outlet 253.

[0032] Specifically, the means for controlling the solenoid valve 40 can be an inductive trigger or a touch button trigger in the prior art. The specific principle is the prior art and will not be described in detail here.

[0033] Through the water connection of this solution and the structural coordination of the water outlet pipe 25, filtered water and temperature-controlled water can be obtained from the same faucet; it is not necessary to set up two faucets to achieve this, and the structure is simplified. In addition, the solenoid valve 40 is set at the front end of the filter element 30, and the filtered clean water is not easily contaminated again.

[0034] More preferably, a control box 50 is further included, and the solenoid valve 40 and the filter element 30 are both fixed on the control box 50. In this way, the solenoid valve 40 and the filter element 30 are integrated into a whole, which is easy to install.

[0035] Specifically, in this embodiment, the control box 50 includes a box body 51 and a first three-way pipe 61, a second three-way pipe 62 and a fixed frame 52 assembled in the box body 51, and the end of the cold water inlet pipe 21 is connected to the first interface 611 of the first three-way pipe 61, and the second interface 612 and the third interface 613 of the first three-way pipe 61 respectively form the first cold water outlet 1 and the second cold water outlet 2.

[0036] The three interfaces of the second three-way pipe 62 are respectively connected to the water outlet of the filter element 30, the outlet of the mixing water pipe 24 and the water outlet pipe 25; specifically, the three interfaces of the second three-way pipe 62 are defined as a fourth interface 621, a fifth interface 622 and a sixth interface 623; the fourth interface 621 of the second three-way pipe 62 is connected to the water outlet of the filter element 30, the fifth interface 622 of the second three-way pipe 62 is connected to the outlet of the mixing water pipe 24, and the sixth interface 623 of the second three-way pipe 62 includes an outer interface 6231 and an inner interface 6232. 32, the outer interface 6231 is communicated with one of the fourth interface 621 and the fifth interface 622, and the inner interface 6232 is communicated with the other of the fourth interface 621 and the fifth interface 622. In this embodiment, the inner interface 6232 is communicated with the fourth interface 621 of the second three-way pipe 62, the outer interface 6231 is communicated with the fifth interface 622 of the second three-way pipe 62, the outer interface 6231 is connected to the outer tube body 251 of the water outlet pipe 25, and the inner interface 6232 is connected to the inner tube body 252 of the water outlet pipe 25.

[0037] The valve housing 41 of the solenoid valve 40 and the first three-way pipe 61 are integrally connected, and the third interface 613 of the first three-way pipe 61 is directly connected to the water inlet end of the valve housing 41 of the solenoid valve 40. At the same time, the first three-way pipe 61 is also integrally connected to the second three-way pipe 62; that is, the valve housing 41 of the solenoid valve 40, the first three-way pipe 61 and the second three-way pipe 62 are integrally connected, reducing the assembly of parts.

[0038] The filter element 30 is fixed on the fixing frame 52. Specifically, the first three-way pipe 61 and the second three-way pipe 62 are fixed on the top of the fixing frame 52, and the filter element 30 is fixed on the bottom of the fixing frame 52; the solenoid valve 40 and the water inlet of the filter element 30 are connected through the first connecting pipe 71; the fourth interface 621 of the second three-way pipe 62 and the water outlet of the filter element 30 are connected through the second connecting pipe 72.

[0039] Furthermore, the fixing frame 52 is a circular frame having an arc-shaped outer side wall, and the valve housing 41, the first three-way pipe 61 and the second three-way pipe 62 of the integrally connected solenoid valve 40 are fixed to the top of the fixing frame 52 by bolts, and the outer periphery of the fixing frame 52 has two groups of upwardly protruding limiting portions 521, and the first connecting pipe 71 and the second connecting pipe 72 are respectively restricted on the two groups of limiting portions 521; specifically, each group of limiting portions 521 are two upwardly protruding limiting protrusions arranged at intervals, and the first connecting pipe 71 or the second connecting pipe 72 is clamped between the two limiting protrusions to respectively realize effective positioning of the first connecting pipe 71 and the second connecting pipe 72.

[0040] At the same time, the radial protrusions on the outer peripheral side of the fixing frame 52 have two rows (of course, there may be more than two rows in other embodiments) of limiting structures, and each row of limiting structures includes a plurality of limiting plates 522 that are spaced and evenly arranged along the outer peripheral side of the fixing frame 52; the first connecting tube 71 and the second connecting tube 72 are both wrapped around the outer peripheral side of the fixing frame 52 and limited by the two rows of limiting structures; in this way, the winding and positioning of the first connecting tube 71 and the second connecting tube 72 are achieved, the assembly is simpler and more stable, and it is not easy to fall apart, and the blockage of the waterway caused by bending is avoided, thereby ensuring the smooth flow of the waterway.

[0041] The water outlet pipe 25 is a pull-out water pipe, and a counterweight block 26 is mounted on the water outlet pipe 25 to form a pull-out water outlet faucet.

[0042] The above-mentioned water channel setting integrates the bottom water channel into a whole through a control box, which is convenient for installation. Figure 7As shown, during on-site installation, the faucet body 11 with the thermostatic valve 12 is installed on the upper surface of the basin 100, while the solenoid valve 40, the filter element 30 and various pipelines are distributed at the bottom of the basin 100, and the space at the bottom of the basin 100 is limited; in this way, the control box 50, the solenoid valve 40 and the filter element 30 and other components are assembled. During on-site assembly, the cold water inlet pipe 21, the hot water inlet pipe 22, the intermediate pipe 23, the mixing water pipe 24 and the outlet pipe 25 are connected accordingly; this is a more preferred embodiment. Of course, in other embodiments, it is not limited to this, such as the control box 50 can adopt other structures, such as the first three-way pipe 61, the second three-way pipe 62 and the valve housing 41 of the solenoid valve 40 are all separate structures, or only two of them are connected as one; or the various components can be integrated without using the control box 50; the composition structure of the waterway can also adopt other methods, etc.
