The temperature is adjusted and the water output is controlled by the thermostatic valve core, and the water outlet is controlled by the water diversion valve core. There are mainly two types of materials: metal and plastic. Metal faucets have high manufacturing costs, and the internal waterways are prone to rust after long-term use, resulting in excessive heavy metal content and affecting safety. Plastic faucets have complex internal pipes, which results in a very complex mold structure for injection molding, making them inconvenient for large-scale mass production. In addition, they are limited by the form of injection molding production, and some structural shapes cannot be manufactured, resulting in poor production convenience. Summary of the invention

[0003] Therefore, in view of the above problems, the present invention provides a combined faucet.

[0005] A further improvement is that the first locking device includes: a mounting seat arranged on the first water outlet pipe, a mounting block arranged on the second main water outlet pipe and matching the mounting seat, locking grooves opened on both sides of the mounting seat, locking ring grooves opened on the mounting block and matching the locking grooves, and a U-shaped plug block inserted in the locking groove and the locking ring groove.

[0006] A further improvement is that: there are two main water inlet holes, a first water inlet connected to any main water inlet hole is opened on the main valve seat, a first main water inlet pipe connected to the other main water inlet hole is arranged on the main valve seat, the other end of the first main water inlet pipe is connected to the mounting seat, the mounting block is also provided with a second main water inlet pipe connected to the first main water inlet pipe, and the second main water inlet pipe is provided with a second water inlet.

[0007] A further improvement is that: there is one main water inlet hole, and a third water inlet connected to the main water inlet hole is provided on the main valve seat; Or a third main water inlet pipe connected to the main water inlet hole is arranged on the main valve seat, and the other end of the third main water inlet pipe is connected to the mounting seat. A fourth main water inlet pipe connected to the third main water inlet pipe is also arranged on the mounting block, and a fourth water inlet is arranged on the fourth main water inlet pipe.

[0008] A further improvement is that the water diversion valve seat assembly includes: a water diversion valve seat connected to the second main water outlet pipe, at least two water diversion outlet holes opened on the water diversion valve seat, and a water diversion outlet pipe arranged on the water diversion valve seat and connected to the water diversion outlet holes respectively.

[0009] A further improvement is that: the number of the water distribution outlet holes is three, the water distribution outlet pipe is arranged to match the water distribution outlet holes, and the water distribution outlet pipe is respectively provided with a top spray outlet, a shower outlet and a lower outlet.

[0010] A further improvement is that the top spray outlet is connected to any water outlet pipe via a second clamping device.

[0011] A further improvement is that the second engaging device includes: a turning pipe connected to the top spray outlet, a engaging block arranged on the water diversion outlet pipe, a plug-in groove opened on the turning pipe for resisting the water diversion outlet pipe, and an L-shaped groove opened on the turning pipe for engaging with the engaging block.

[0014] The advantages and beneficial effects of the present invention are: 1. Simple structure and convenient production. By disassembling the valve core body into multiple parts, the difficulty of manufacturing the mold is reduced, which is convenient for mass production of molds and manufacturing. After the plastic valve core body is disassembled, it can be combined into more different shapes to adapt to more usage environments, thereby improving production convenience.

[0015] 2. The valve core body can be made of food-grade plastic material. After long-term use, it will not rust or release heavy metal substances. It is highly safe to use. A protective shell made of metal material can also be set on its outside to play a protective role, increase its service life, and enhance its aesthetics. Furthermore, since the protective shell and the valve core body are in a separate state, when hot water is released, the temperature of the protective shell is different from the temperature of the valve core body. When the user touches the protective shell, it is not easy to be scalded, which further enhances the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS
