Technical Field

[0001] This utility model relates to the field of bathroom technology, specifically to a filter faucet. Background Technology

[0002] Scale and rust inevitably exist during the transportation of tap water. As people's living standards improve, they want to filter tap water when it comes out of the tap, so faucets with filtering functions have been introduced to the market.

[0003] Most current faucets have an external, independent vertical filter compartment installed on the back, which takes up space at the back of the faucet, requiring a large installation space to be reserved at the back of the faucet. Furthermore, the water path between the faucet and the filter compartment is complex, resulting in high production costs.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A filter faucet includes an outer shell, a faucet inner core, a valve core body, a filter element, and a filter chamber shell. The outer shell has an internal mounting cavity for installing the faucet inner core. A first side tube and a second side tube are connected to the sides of the outer shell, and a top tube is located on the top of the outer shell. The inner cavities of the first side tube, the second side tube, and the top tube all communicate with the mounting cavity. The faucet inner core is installed within the mounting cavity, and the top of the faucet inner core has a water outlet section that extends into the top tube. The sides of the faucet inner core have a... The valve core mounting surface of one side pipe and the filter element mounting surface facing the second side pipe are provided; the valve core mounting surface is provided with an inlet and an outlet, the inlet is connected to the inlet pipe of the faucet inner core, the valve core body is fixedly installed in the first side pipe and abuts against the valve core mounting surface; the outlet extends to the filter element mounting surface, and the filter element mounting surface is also provided with an outlet connecting to the outlet section; the filter chamber shell is fixedly connected to the second side pipe, the filter chamber shell and the filter element mounting surface form a filter chamber, and the filter element is disposed in the filter chamber.

[0008] Furthermore, the filter element is a hollow column, with its end abutting against the filter element mounting surface, and the water outlet and the water inlet are separated by the filter element.

[0009] Furthermore, the outer periphery of the filter element mounting surface extends towards the second side tube to form a second cylindrical wall, and a sealing ring is provided between the outer wall of the filter chamber shell and the inner side of the second cylindrical wall.

[0010] Furthermore, the outer periphery of the valve core mounting surface extends towards the first side tube to form a first cylindrical wall; the first cylindrical wall and the second cylindrical wall are coaxially arranged; the valve core mounting surface and the filter element mounting surface are arranged in parallel.

[0011] Furthermore, the filter housing is made of a transparent material.

[0012] Furthermore, the inner wall of the second side tube is provided with a second internal thread, and the filter chamber shell is formed with a second external thread, and the filter chamber shell is threadedly connected to the second side tube.

[0013] Furthermore, the valve core is a hot and cold water mixing valve core, the water inlet pipe of the faucet inner core is divided into a cold water pipe and a hot water pipe, and the valve core mounting surface is provided with a water inlet divided into a cold water inlet and a hot water inlet; a pressure cap is provided on the first side pipe, and a handle is also installed on the valve core.

[0014] Furthermore, a guide groove is formed on the outer wall of the water outlet section, and a guide protrusion is formed on the inner wall of the top pipe. When the water outlet section extends into the top pipe, the guide protrusion slides and engages with the guide groove.

[0017] With the above structure, the filter faucet of this utility model has at least the following beneficial effects:

[0018] 1. The faucet core is separated and housed within the outer casing, simplifying the water circuit design. After water flows into the valve core, it flows from the inlet to the filter chamber, and after being filtered by the filter element, it flows from the outlet to the outlet section.

[0019] Second, by setting the valve core mounting surface and the filter element mounting surface, the valve core body and the filter element are fixed to the faucet inner core from both sides after installation, so that the faucet inner core and the outer shell form a stable connection.

[0034] Thus, the filter faucet of this utility model simplifies the water circuit design by using a faucet inner core 2 separately set inside the outer shell 1. Preferably, the faucet inner core 2 is integrally injection molded from plastic material.

[0035] After the water flows into the inlet valve core 3, it flows from the inlet 222 to the filter chamber 51. After being filtered by the filter element 4, it flows from the outlet 231 to the outlet section 21.

[0036] Specifically, the filter element 4 is a hollow column, with its end abutting against the filter element mounting surface 23. The outlet 231 and the inlet 222 are separated by the filter element 4.
