The sealing member 850 can achieve a good sealing effect, and reduce the risk of water leakage.

The water outlet connector 220 may be connected to the filter housing 600 by any suitable means such as a threaded connection, a connector connection, or welding. The water outlet joint 220 is provided with a water channel 430. Waterway 430 may be in communication with cartridge inlet 610. Specifically, the waterway channel 430 may have an inlet end 431 and an outlet end 432. The water inlet end 431 may be connected to the valve housing 200. Water outlet end 432 may be connected to cartridge inlet 610. When the valve core 300 is located at the water purification station, raw water may sequentially pass through the water inlet 210, the waterway channel 430 and the filter core water inlet 610, and thus enter the filter core 700 for filtration. After the raw water is filtered, purified water can be formed. The purified water may flow out through the cartridge outlet 620.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and many variations and modifications can be made according to the teaching of the present invention. For example, the valve core 300 may further have a water purification station and a raw water station, such as a communication station where the water inlet 210 is communicated with the water outlet 220 and the raw water outlet 230, a stop station where the water inlet 210 is stopped with the water outlet 220 and the raw water outlet 230, and the like. Such variations and modifications are intended to fall within the scope of the present invention as claimed.

The outlet end 432 of the waterway 430 may extend at a predetermined angle with respect to the centerline of the cartridge inlet 610. The predetermined included angle may be an acute angle. It should be noted that the predetermined included angle is a smaller included angle between the extending direction of the water outlet end 432 and the central line of the water inlet 610 of the filter element. In the embodiment shown in fig. 3, the angle at which the opening faces upward is the predetermined angle. Illustratively, the acute angle may be any angle including, but not limited to, 85 °, 80 °, or 70 °, and the like.

After the raw water passes through the water outlet end 432, the flow direction of the water flow is the same as the extending direction. As such, the water flow does not vertically strike the filter cartridge 700, but has the same angle as the predetermined angle with respect to the filter cartridge 700. Thus, the filter element 700 is less impacted by the water flow, and the risk of damage to the filter element is reduced, so that the performance of the faucet water purifier is reliable. And, when filter core 700 receives water impact, the vibration and the noise that produce can reduce, and user's use experience is better. Therefore, the faucet water purifier has better market competitiveness.

It should be noted that, the faucet water purifier of the embodiment of the present invention only needs to ensure that the extending direction of the water outlet end 432 of the waterway 430 and the center line of the filter core water inlet 610 have a predetermined included angle, and the directions of other portions of the waterway 430 are not limited. In other words, the overall shape of the waterway 430 is not limited. In the embodiment shown in fig. 6, the waterway passage 430' may have a straight shape inclined upward. In the embodiment shown in fig. 7, waterway channels 430 "may be in the shape of a dogleg. In the embodiment shown in fig. 8, the waterway channels 430 "' may be curved. In other embodiments not shown in the figures, the waterway may also be wavy or have any other suitable shape.

For example, referring back to fig. 1-5, waterway 430 may be rectilinear. So set up, waterway 430 is easy to process, low in manufacturing cost. Also, the length of the waterway channel 430 is relatively short, so that power consumption of the faucet water purifier can be reduced. Therefore, the faucet water purifier is more energy-saving and environment-friendly.

Illustratively, the waterway channel 430 may gradually extend downward in a direction from the water inlet end 431 to the water outlet end 432 thereof. The downward extension includes a continuous downward extension, such as the embodiment shown in fig. 3. The downward extension also includes intermittent downward extensions, such as the embodiments shown in fig. 7 and 8. With this arrangement, the raw water does not need to overcome gravity in the process of flowing from the water inlet end 431 to the water outlet end 432 of the waterway channel 430. Therefore, the faucet water purifier has lower power consumption and is more energy-saving and environment-friendly.

For example, the water outlet joint 220 may be coaxially disposed with the waterway channel 430. With such an arrangement, the water outlet joint 220 has a simple structure and is convenient to manufacture. Moreover, the water outlet joint 220 can directly adopt a common pipeline, thereby being convenient for purchase and reducing the manufacturing cost.

Illustratively, the faucet water purifier may also include a seal 420. The seal 420 may surround the water outlet end 432 of the waterway 430. The seal 420 may be clamped between the outlet fitting 220 and the filter housing 600. As such, the seal 420 may seal between the outlet fitting 220 and the filter housing 600. The seal 420 includes, but is not limited to, a seal ring or a gasket, etc. The sealing member 420 can achieve a good sealing effect, and reduce the risk of water leakage.

For example, the water outlet joint 220 may be provided with a mounting portion 240. The mounting portion 240 may surround the water outlet end 432 of the waterway channel 430. The sealing member 420 may seal between the mounting part 240 and the filter housing 600. By providing the mounting portion 240, there is more space for disposing the sealing member 420, so that the manufacturing difficulty can be reduced, thereby reducing the manufacturing cost.

Illustratively, the mounting portion 240 may be provided with an annular groove 241. The annular groove 241 may surround the water outlet end 432 of the waterway channel 430. The seal 420 may be mounted to the annular groove 241 by any suitable means, such as adhesive or snap fit. In this way, the seal 420 may be effectively secured against dislodgement.

Illustratively, the water outlet end 432 of the waterway channel 430 may be inserted into the filter housing 600. The faucet water purifier may also include a fastener 400. The fastener 400 may be fastened to the water outlet end 432 of the waterway channel 430. The filter case 600 may be clamped between the fastener 400 and the mounting part 240. Fasteners 400 include, but are not limited to, screws, bolts, or rivets, among other fasteners. By such arrangement, the connection structure between the water outlet joint 220 and the filter casing 600 is simple, and the manufacturing cost is low.

Illustratively, the outer circumferential surface of the water outlet end 432 may be provided with external threads 250. The fastener 400 may be provided with internal threads 410. The external threads 250 may be coupled to the internal threads 410. Thus, the water outlet joint 220 and the filter casing 600 are convenient to assemble and disassemble.

Illustratively, the fastener 400 may comprise a nut. Thus, the fastener 400 is compact and inexpensive to manufacture. And, the fastener 400 can select a standard nut, so that it can be directly purchased, and an independent design and manufacture is avoided, thereby reducing the cost of the faucet water purifier.
