[0022] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0024] The following is combined with Figure 1-5 The specific implementation methods of this application are further described.

[0025] Example:

[0026] The present application embodiment discloses a lead-free kitchen faucet that is easy to manufacture, referring to Figure 1 As shown, it includes a faucet switch body 1, a faucet water outlet pipe body 2, and a water outlet core 3. The faucet switch body 1 is a prior art and is well known in the existing market. It has a valve core inside and a handle outside. The handle controls the movement of the valve core, and the valve core can control the switching of the water path. In this solution, the water outlet core 3 cooperates with the faucet switch body 1 to realize the on-off control of the water path.

[0027] The external water inlet pipe is connected to the water outlet core 3 to provide water pressure and water source.

[0028] The faucet switch body 1 is connected to the water outlet core 3 to control the opening and closing of the water inlet 33 of the water outlet core 3, and the faucet water outlet pipe body 2 is connected to the water outlet 34 of the water outlet core 3 to discharge water.

[0029] Combination Figure 2 , Figure 3 and Figure 4 As shown, the specific structure of the water path of the water outlet core 3 is as follows. The water outlet core 3 is made of lead-free material, replacing the previous lead-containing copper material. The water outlet core 3 includes an inner core 31 and an outer core 32. The outer core 32 is sleeved with the inner core 31 and fixed on the faucet switch body 1 by threaded connection. The water inlet pipe is connected to the inner core 31 to provide water source and water pressure. The inner core 31 is provided with a water cavity 1 311 and a water outlet hole 1 312. The outer core 32 and the faucet water outlet pipe body 2 are formed with a water cavity 2 321 and a water outlet hole 24. The water outlet hole 1 312 and the water cavity 2 321 are connected and communicated through an adapter 4. The water outlet hole 2 24 is located on the faucet water outlet pipe body 2.

[0030] exist Figure 5 It can be seen that the original integrated structure of the water outlet core 3 is split into a design, so that the inner core 31 and the outer core 32 are assembled, so as to facilitate processing and manufacturing, and other materials can be used to replace the original copper material, so as to reduce costs and avoid the use of lead-containing copper. When the water flow stays in the water outlet core 3 to store water, it does not come into contact with lead, which is safer and more environmentally friendly, and the flow control of the water flow is completed. The inner core 31 and the outer core 32 are connected by the adapter 4, and at the same time, a reliable water channel seal is completed to avoid water leakage.

[0031] The inner core 31 is made of plastic, and the outer core 32 is made of stainless steel. Such a combination can also achieve a longer service life, meet user needs, and greatly reduce manufacturing costs.

[0032] In this solution, in order to improve the sealing effect of the water channel and avoid water leakage, the faucet water outlet pipe body 2 includes a shaft sleeve portion 21, a pipe body portion 22 and a water outlet head 23, and the shaft sleeve portion 21 is sleeved on the outer core 32, so that the faucet water outlet pipe body 2 can be rotated, and at the same time, because the outer core 32 is provided with an upper sealing ring 35 and a lower sealing ring 36, the second water cavity 321 is located between the upper sealing ring 35 and the lower sealing ring 36, and the second water outlet hole 24 is located on the shaft sleeve portion 21. In this way, the faucet water outlet pipe body 2 will not leak when the faucet water outlet pipe body 2 is rotated.

[0033] In order to make the water path connection position of the inner core 31 and the outer core 32 more tightly assembled, firm and reliable in sealing. The adapter 4 is threadedly connected to the water outlet hole 1 312 of the inner core 31 and spans the inner core 31 and the outer core 32. The adapter 4 is provided with a front sealing ring 41 and a rear sealing ring 42. The front sealing ring 41 abuts against the inner core 31, and the rear sealing ring 42 abuts against the outer core 32. In this way, the direction of the water path is changed, so that the water outlet direction is toward the water cavity 2 321. Since the water path is formed by the inner core 31 and the outer core 32, the sealing effect is guaranteed by the front sealing ring 41 and the rear sealing ring 42.

[0034] In order to make the faucet outlet pipe body 2 sleeve-mounted and rotated more easily and smoothly, the lower end of the inner core 31 is fixedly connected with a support seat 5, and the support seat 5 supports the lower end of the shaft sleeve part 21. The faucet outlet pipe body 2 is limited up and down and is not easy to move up and down.

[0035] In order to facilitate installation on the basin, the outer core 32 is threadedly connected with a screw rod 6, and the screw rod 6 is threadedly connected with a countertop lower seat 7, and the countertop lower seat 7 is provided with a semi-ring portion 71. In this way, the upper and lower positions of the countertop lower seat 7 can be adjusted by the screw rod 6, and the countertop lower seat 7 can be fastened under the countertop.

[0036] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
