[0029] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail through specific embodiments below.

[0030] As Figures 1 to 4 shown, it is a split pull-out faucet related to the present invention, including a main housing 1, a sub-housing 2, an installation ring 3 and a valve core seat 4. A pipeline cavity 11 and a valve core cavity 12 that communicate with each other are formed in the main housing 1, and the valve core seat 4 is installed between the pipeline cavity 11 and the valve core cavity 12; an installation cavity 21 is formed in the sub-housing 2, and the installation cavity 21 communicates with the pipeline cavity 11, and the sub-housing 2 is fixed on the main housing 1 through the installation ring 3. During installation, the user only needs to reach into the valve core cavity 12 to tighten the sub-housing 2 on the main housing 1 with the installation ring 3, and then turn the valve core seat 4 and the valve core 5 into the valve core cavity 12 in sequence and fix them with the gland 6. The installation is fast and convenient. The split design of the valve core seat 4 and the sub-housing 2 can be injection molded with plastic, which has lower cost compared to being directly formed on the metal main housing 1, so it has better economy.

[0031] Preferably, the sub-housing 2 and the installation ring 3 are fixedly connected by threads. Preferably, a first step 13 is formed on the main housing 1, the sub-housing 2 abuts against the outside of the first step 13, and the installation ring 3 abuts against the inside of the first step 13. In this way, the sub-housing 2 and the installation ring 3 can be clamped on the main housing 1 with threads.

[0032] Preferably, as Figure 4 shown, a plurality of tooling grooves 31 are also formed on the installation ring 3. By providing the tooling grooves 31, it is convenient to tighten the installation ring 3 so that the sub-housing 2 is fixed on the main housing 1.

[0033] Preferably, a digital display module or an infrared induction module or a filter element (not shown in the figure) is installed in the installation cavity 21. The pipelines or circuits of the digital display module or the infrared induction module or the filter element can communicate with the power generation module or the water circuit through the pipeline cavity 11.

[0034] Preferably, the sub-housing 2 is made of transparent plastic material, and the valve core seat 4 is made of plastic material. In this way, the temperature displayed by the digital display module or the usage condition of the filter element can be viewed through the transparent sub-housing 2, and it is also convenient for the infrared induction module to emit infrared rays, and the user can control the switch of the faucet without touching.

[0035] Preferably, a second step 14 is formed in the main housing 1, a third step 41 is formed on the valve core seat 4, the second step 14 and the third step 41 are abutted and connected, a valve core 5 is installed on the valve core seat 4, and a gland 6 is threadedly connected in the main housing 1. The gland 6 abuts the valve core 5 against the valve core seat 4. In this way, the valve core seat 4 is also abutted against the second step 14 by the valve core 5, making the installation more convenient.

[0036] Preferably, as Figure 3 and Figure 4 shown, a positioning groove 15 is formed in the main housing 1, a positioning block 42 is installed on the valve core seat 4, and the positioning block 42 is inserted into the positioning groove 15. In this way, the axial rotation of the valve core seat 4 can be restricted, avoiding the offset of the valve core seat 4 when the gland 6 is installed and tightened.

[0037] Preferably, the positioning block 42 and the valve core seat 4 are fixedly connected by threads. In this way, the protruding height of the positioning block 42 can be adjusted by screwing the threads, making the positioning effect more stable and smooth.

[0038] Preferably, a water outlet pipe 7 is installed at the upper end of the main housing 1, and the water outlet pipe 7 is communicated with the pipe cavity 11. During use, a draw tube is installed in the water outlet pipe 7, the lower end of the draw tube is connected to the pipe cavity 11 and is connected to the lower water outlet end of the valve core seat 4. A cold and hot water inlet pipe is also installed in the pipe cavity 11, and the cold and hot water inlet pipe is connected to the lower water inlet end of the valve core seat 4. In this way, the water flow enters the valve core seat 4 and leads to the mixing valve core 5, and after being mixed by the valve core 5, it then flows into the draw tube from the lower water outlet end of the valve core seat 4.

[0039] Compared with the prior art, the present utility model is a split draw faucet, which is more convenient to install. The auxiliary housing 2 and the valve core seat 4 are made of plastic material, having good economy.
