An embodiment of the present invention provides a water purification faucet, please refer to fig. 1 to 6, which includes: the water-saving device comprises a main machine 10, wherein the main machine 10 comprises a water inlet flow channel 11 and a water outlet flow channel 12, one end of the water inlet flow channel 11 is used for receiving water, and the water outlet flow channel 12 is used for discharging water; the filter cartridge 20, the filter cartridge 20 includes the filter chamber 21 and outlet port, the outlet port is used for discharging the water body after filtering; the flow channel switching part 30, the flow channel switching part 30 is arranged in the main machine 10, the flow channel switching part 30 has a switching flow channel 34, the switching flow channel 34 is communicated with the filter cavity 21, the flow channel switching part 30 is provided with a water inlet hole 31, and the water inlet hole 31 is communicated with the switching flow channel 34; wherein, the other end of the water inlet channel 11 is selectively communicated with the water outlet channel 12 or the water inlet hole 31.

The water purifying faucet of an embodiment of the present invention can realize the switching of filtering or not filtering the water entering the main machine 10 through the main machine 10, the filter cartridge 20 and the flow channel switching part 30. When the water filter is used specifically, a water body enters the main machine 10 through the water inlet channel 11, if the water body needs to be filtered, the water inlet channel 11 is communicated with the water inlet hole 31, and the water body sequentially passes through the water inlet channel 11, the water inlet hole 31 and the switching channel 34 and enters the filter cavity 21. On the contrary, if the water body does not need to be filtered, the water inlet channel 11 is communicated with the water outlet channel 12, and the water body enters the water outlet channel 12 through the water inlet channel 11, that is, the water body does not enter the switching channel 34. The utility model discloses a water purification tap not only can satisfy the filtration to the water, when need not to filter, also can normally discharge the water moreover, and its commonality is higher relatively.

In one embodiment, whether the water is filtered or not depends primarily on whether the inlet channel 11 is in communication with the outlet channel 12 or the inlet opening 31. The water inlet channel 11 and the water outlet channel 12 may be regarded as cavities inside the main unit 10.

In one embodiment, the flow path switching part 30 is rotatably provided in the main body 10 such that the water inlet hole 31 has a first position communicating with the water inlet flow path 11 and a second position disconnecting from the water inlet flow path 11. When the water inlet hole 31 is located at the first position, the water inlet channel 11 is communicated with the water inlet hole 31, so that the water in the water inlet channel 11 flows into the filter cavity 21 through the channel switching part 30; when the inlet hole 31 is located at the second position, the inlet flow passage 11 is communicated with the outlet flow passage 12.

In one embodiment, the rotation position of the flow switching part 30 determines whether the water in the inlet flow channel 11 enters the inlet hole 31 or the outlet flow channel 12, that is, when the inlet hole 31 is located at the first position, the inlet hole 31 is located opposite to the outlet of the inlet flow channel 11, so as to receive the water in the inlet flow channel 11, and at this time, the inlet hole 31 and the outlet of the inlet flow channel 11 may be in contact with or spaced from each other, as long as it is ensured that the inlet hole 31 can receive the water discharged from the inlet flow channel 11. When the water inlet hole 31 is located at the second position, the water inlet hole 31 is staggered with the water outlet of the water inlet runner 11, so that the water body of the water inlet runner 11 cannot be received. As shown in fig. 5, the first state of the purified water faucet is a state in which the water inlet hole 31 is staggered with the water outlet of the water inlet channel 11, and the water body is not filtered. As shown in fig. 6, the second state of the purified water faucet is a state where the water inlet hole 31 is opposite to the water outlet of the water inlet channel 11, and the water body is filtered.

As shown in fig. 2 and 3, the fresh water faucet further includes: and a switch part 40, wherein the switch part 40 is connected with the flow channel switching part 30 and is rotatably arranged relative to the main body 10 to drive the flow channel switching part 30 to rotate relative to the main body 10.

When the flow path switching part 30 rotates again, the ball 52 will disengage from the groove 13 and rotate with the flow path switching part 30 until it is opposite to the groove 13 again. Wherein, two grooves 13 are provided, and the two grooves 13 correspond to two position states of the water inlet hole 31 at the first position or the second position.

In one embodiment, the elastic member 51 is a spring, the ball 52 is a plurality of steel balls, and the plurality of steel balls are sequentially arranged along the extending direction of the mounting hole 32; wherein, the part of one steel ball in a plurality of steel balls is arranged in the spring in a penetrating way. The compressed or expanded state of the spring is determined by the mutual position relationship of the opening of the mounting hole 32 and the groove 13, and the arrangement of a plurality of steel balls is mainly used for increasing the reminding sound, namely, the steel balls collide with each other due to the position change to generate the reminding sound.

In one embodiment, when the flow passage switching portion 30 rotates, all of the plurality of steel balls may rotate with the flow passage switching portion 30, i.e., all of the steel balls are located within the mounting holes 32. In a specific design, at least one steel ball may be held in the groove 13, i.e. not rotated with the flow channel switching part 30, and when the opening of the mounting hole 32 is opposite to the groove 13, the steel ball in the mounting hole 32 may collide with the steel ball in the groove 13.
