[0041] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0042] refer to Figures 1 to 4 As shown, a preferred embodiment of the present invention provides a pull-out faucet, including a water outlet assembly, a faucet body 40, and a hose assembly 30. The water outlet assembly includes a water outlet body 10 having an inlet end and an outlet end, and a switch valve 20 disposed on the water outlet body 10. The switch valve 20 communicates with the inlet end and the outlet end respectively to control the connection or disconnection of the inlet end and the outlet end. The faucet body 40 has a through cavity. A first end of the faucet body 40 is used to fix it to a mounting surface, and a second end is detachably connected to the water outlet body 10. The hose assembly 30 passes through the through cavity and is connected to the inlet end.

[0043] When applied to a kitchen faucet, the faucet should be rotatable from the sink countertop. A base 90 is provided at the first end of the faucet body 40, and the base 90 is fixed to the sink countertop, thus the faucet body 40 and the base 90 are rotatably connected. When the user needs to remove the faucet outlet from the faucet body 40 to rinse any part of the sink, the outlet body 10 includes a connector section with the water inlet end, which is pluggable to the second end of the faucet body 40. An elastic positioning component 81 is provided on the side wall of the connector section, and a positioning hole 82 corresponding to the elastic positioning component 81 is provided on the faucet body 40. The elastic positioning component 81 includes an elastic element 811 and a positioning pin 812. When the connector section is inserted and aligned with the second end of the faucet body 40, the positioning pin 812 automatically engages with the positioning hole 82 under the elastic force of the elastic element 811.

[0044] The water outlet body 10 has a first opening, a second opening, and a third opening. The switch valve 20 passes through the first opening, the second opening forms the water outlet end, and the third opening forms the water inlet end. The water inlet end has at least two water inlets 11, which communicate with the first opening to form a water inlet path. The water outlet end has at least one water outlet 12, which communicates with the first opening to form a water outlet path. The switch valve 20 includes at least two valve inlets. The valve 20 includes at least one valve inlet and at least one valve outlet. The valve inlet communicates with the inlet 11, and the valve outlet communicates with the outlet 12. In this embodiment, there are two inlets 11, each connected to a flexible hose 30. The two hoses 30 are respectively connected to a cold water supply and a hot water supply, forming two water inlet paths. There is one outlet 12, forming one water outlet path. The switch valve 20 includes two valve inlets and one valve outlet. (Cold and hot water supply options are listed here.) Water flows from the two hoses 30 to the two inlet water passages, then to the valve inlet, and finally mixes and distributes from the switch valve 20 to the outlet water passage. A nut 50 is placed on top of the switch valve 20, and the nut 50 is fixedly connected to the outlet body 10 to secure the switch valve 20 in the first opening. The sealing surface of the switch valve 20 and the sealing surface of the first opening are pressed tightly together to ensure that there is no leakage between them. An operating handle 60 is placed on top of the nut 50. The operating handle 60 is fixedly connected to the operating rod of the switch valve 20. The operating handle 60 can be a knob, button, or anything else that can be used to connect to and operate the switch valve 20. In this embodiment, the operating handle 60 is a knob. Rotating the knob controls the operating rod to turn on the water source. Continuing to rotate the knob causes the water temperature to transition from low to high, and vice versa, the water temperature transitions from high to low, and then the water source is turned off. This allows the user to control the flow and temperature of the water path when operating the operating handle 60. The distance from the center axis of the third opening to the upper surface of the first opening is greater than 20mm. Preferably, the distance from the center axis of the third opening to the upper surface of the first opening is greater than 40mm. In this embodiment, the distance from the center axis of the third opening to the upper surface of the first opening is 45mm, so that the user has enough space to hold the water outlet body 10 when rinsing. Furthermore, the distance from the central axis of the third opening to the upper surface of the operating handle 60 is greater than 25mm; preferably, the distance from the central axis of the third opening to the upper surface of the operating handle is greater than 60mm; in this embodiment, the distance from the central axis of the third opening to the upper surface of the operating handle is 65mm, so that when the user holds the water outlet body 10 to rinse, the operating handle 60 can be operated with one hand using the index finger and thumb.An aerator 70 is provided on the water outlet 12. The aerator 70 can control the water flow rate and water spray pattern to provide users with comfortable water use. The length of the water outlet path is less than 50mm; preferably, the length of the water outlet path is less than 30mm; in this embodiment, the length of the water outlet path is 20mm. The distance the water travels from the switch valve 20 to the water outlet path and then to the aerator 70 is extremely short, which helps users obtain water quickly, reduces the processing materials of the water outlet body 10, saves costs, and improves processing efficiency due to the short length of the water outlet path.

[0045] In another embodiment, the number of water inlets 11 includes three, each water inlet 11 is connected to a corresponding hose 30, and the three hoses 30 are respectively connected to cold water supply, hot water supply and purified water supply, forming three water inlet paths; the number of water outlets 12 includes two, forming two water outlet paths; the cold and hot water flows from the corresponding hoses 30 into the water inlet path and then flows to the switch valve 20, and then mixes and distributes from the switch valve 20 to one of the water outlet paths; the purified water supply flows from the corresponding hose 30 into the purified water path and then flows to the switch valve 20, and then distributes from the switch valve 20 to the other water outlet path; the number of water inlets 11 and water outlets 12 is not limited to these embodiments, and other settings of the number of water inlets 11 and water outlets 12 are within the protection scope of this invention; the switch valve 20 is divided into many types according to water path and function, and the selection of the switch valve 20 depends on specific needs. Other structures that are the same will not be elaborated upon here.

[0046] This invention can also be applied to basin faucets, where the faucet and countertop do not need to rotate relative to each other. A base is provided at the first end of the faucet body 40, and the base is fixed to the countertop. Alternatively, the base may not be required, and the faucet body 40 can be directly fixed to the countertop. The faucet body 40 is fixedly connected to the water outlet body 10, thus meeting user needs. Other structures are the same and will not be described in detail here.

[0047] The working principle of this invention is briefly described as follows:

[0048] Taking two inlets 11 connected to hot and cold water respectively and one outlet 12 as an example, each of the two inlets 11 is connected to a flexible hose 30. The two flexible hoses 30 pass through the faucet body 40 and are connected to the water supply under the countertop, thereby forming two water inlet channels from the flexible hose 30 to the inlet 11 and then to the switch valve 20, and one water outlet channel from the switch valve 20 to the outlet 822. The user controls the water flow state of the switch valve 20 by operating the operating handle 60, and the water flows out through the outlet channel for the user's use. When a user needs to flexibly rinse a hard-to-reach area in the sink with water, the user holds the water outlet body 10 and pulls it out from the faucet body 40. The two hoses 30 are pulled out along with the water outlet body 10. The positioning pin 812 contracts under the action of the side wall of the faucet body 40, and the elastic element 811 is simultaneously compressed. When the water inlet end face of the water outlet body 10 moves away from the first end face of the faucet body 40, the positioning pin 812 bulges upward under the elastic force of the elastic element 811, separating the faucet body 40 from the water outlet body 10. The user then holds the water outlet body 10 and, according to the length of the hoses 30 that can be pulled out, directs the water flow... The nozzle 12 is aligned with the area to be cleaned and water is sprayed. After rinsing, the user inserts the inlet end of the water outlet body 10 back into the faucet body 40. The two hoses 30 are inserted into the faucet body 40 along with the water outlet body 10. The hoses extending out of the faucet body 40 are placed under the countertop. The positioning pin 812 is compressed by the side wall of the faucet body 40, and the elastic element 811 is compressed at the same time. When the positioning pin 812 corresponds to the positioning hole 82, the elastic element 811 extends to press the head of the positioning pin 812 against the positioning hole 82. The faucet body 40 and the water outlet body 10 are connected to each other by the positioning mechanism 80.

[0049] This invention connects the hose 30 directly to the water outlet body 10, and the water outlet 12 of the switch valve 20 is the water outlet 12 of the faucet. This is equivalent to directly connecting the hose 30 to the switch valve 20 and directly supplying water to the user. This structure is simple, easy to form, and easy to manufacture, thereby reducing manufacturing and production costs. The water outlet can switch between multiple functions through the switch valve 20, and multiple hoses 30 can be pulled out with the water outlet body 10 through the pluggable connection between the water outlet body 10 and the faucet body 40, forming a faucet that integrates a temperature control switch and a pull-out mechanism to meet various usage needs and provide users with a variety of experiences. The faucet body 40 only serves as a support component fitted onto the hose 30, making the faucet's appearance simple and beautiful, and the manufacturing process is simple, which helps to reduce manufacturing costs.

[0050] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
