Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0044] Combine Figures 1 to 12, this embodiment provides a multifunctional water outlet pipe structure, including an outer tube 1 and a first water outlet hose 2 and a second water outlet hose 3 sleeved in the outer tube 1, the water inlet end of the outer tube 1 is provided with a water inlet joint 4, and the water outlet end thereof is provided with a water outlet joint 5, the water inlet joint 4 has a first water inlet 41, a second water inlet 42 and a third water inlet 43, the water outlet joint 5 has a first water outlet 51, a second water outlet 52 and a third water outlet 53, wherein the first water outlet hose 2 is used to connect the first water inlet 41 and the first water outlet 51 to form a first water path for hot purified water to pass through, the second water outlet hose 3 is used to connect the second water inlet 42 and the second water outlet 52 to form a second water path for cold purified water to pass through, and the outer tube 1 is used to connect the third water inlet 43 and the third water outlet 53 to form a third water path for tap water to pass through between the outer walls of the two water outlet hoses and the inner wall of the outer tube 1.

[0045] It should be noted that in this embodiment, by inserting the first and second outlet hoses 2 and 3 within the outer tube 1 to form three water paths, a single outlet pipe structure is used to provide hot purified water, cold purified water, and tap water. This creates a simple and compact structure, reducing the space occupied by the outlet pipe structure. Furthermore, the addition of a hot purified water path facilitates user access to hot purified water, meeting user needs in different usage scenarios.

[0046] In a preferred embodiment, the outlet end of the water inlet connector 4 is formed with a first jack 44 communicating with the first water inlet 41 and a second jack 45 communicating with the second water inlet 42. The first water outlet 51 and the second water outlet 52 are both hole-shaped. The ends of the first water outlet hose 2 are respectively inserted into the first jack 44 and the first water outlet 51, while the ends of the second water outlet hose 3 are respectively inserted into the second jack 45 and the second water outlet 52. Exemplarily, both the first water outlet hose 2 and the second water outlet hose 3 are silicone hoses, which facilitates conformal routing with the outer tube 1 to accommodate the outer tube 1's appearance. Furthermore, the silicone hose is preferably made of food-grade material to prevent the release of harmful substances and ensure that the quality of tap water and purified water is not affected by the two outlet hoses. During installation, the water inlet end of the first water outlet hose 2 is inserted into the first plug hole 44, the water outlet end of the first water outlet hose 2 is inserted into the first water outlet 51, the water inlet end of the second water outlet hose 3 is inserted into the second plug hole 45, and the water outlet end of the second water outlet hose 3 is inserted into the second water outlet 52. It is easy to install and quick to disassemble, and it is convenient for maintenance and replacement of the water outlet pipe structure.

[0047] In another embodiment, the water inlet connector 4 is shaped like a stepped shaft, with the first water inlet 41 located on the first step of the stepped shaft, the second water inlet 42 located on the second step of the stepped shaft, and the third water inlet 43 located on the third step of the stepped shaft. For example, the stepped shaft configuration of the water inlet connector 4 makes the structure of the water inlet connector 4 more compact, avoiding the large size of the water inlet connector 4 that would affect the diameter of the outer tube 1 and also saving costs. Furthermore, the stepped configuration avoids the problem of each water inlet being located on the same plane, which would limit the water inlet area and result in a low water flow rate.

[0048] On the basis of the above-mentioned embodiment, in an optional embodiment of the present invention, the water outlet end of the outer tube 1 is threadedly connected to a pressure cap 6 for compressing the water outlet connector 5. The outer circumferential size of the pressure cap 6 is set to be the same as the outer circumferential size of the outer tube 1 to ensure the simplicity of the appearance. A limiting portion 55 is provided on the water outlet connector 5, and the limiting portion 55 is set to abut against the end face of the threaded portion 11 on the outer tube 1 through the action of the pressure cap 6, thereby achieving the limitation of the water outlet connector 5. During installation, first connect the water inlet ends of the first water outlet hose 2 and the second water outlet hose 3 to the water inlet connector 4, and then insert them into the outer tube 1. The length of the two water outlet pipes is greater than the length of the outer tube, so that the two water outlet hoses can be pulled outward from the water outlet end of the outer tube 1 for a distance to facilitate connection with the water outlet connector 5. After the outlet hose is connected to the outlet connector 5 , the outlet connector 5 is placed into the outer tube 1 so that the limiting portion 55 abuts against the end surface of the outer tube 1 , and then the gland 6 is screwed in along the threaded portion 11 to tighten the outlet connector 5 .

[0049] Preferably, a bubbler 7 is arranged between the pressure cap 6 and the water outlet joint 5, and the bubbler 7 is connected to the third water channel. For example, the water outlet end of the water outlet joint 5 is provided with a water outlet channel 54 bulging along the center position, and the water outlet channel 54 is connected to both the first water channel and the second water channel, and is provided through the bubbler 7. The pressure cap 6 presses the bubbler 7 and the water outlet joint 5 in turn, which simplifies the installation steps, and the threaded connection also facilitates disassembly and assembly. Tap water flows out from the bubbler 7, which has a large water outlet area, making it convenient for users to flush, and the bubbler 7 can prevent water from splashing. Both hot purified water and cold purified water flow out from the water outlet channel 54, which can reduce the number of water outlets and simplify the water outlet structure. The purified water is separated from the tap water to prevent the tap water from contaminating the purified water outlet.

[0050] Another embodiment of the present invention provides a faucet, comprising a faucet body 8 and a multifunctional water outlet pipe structure as described in any of the above embodiments, adapted to be connected to the faucet body 8. For example, the faucet body 8 is provided with a first control valve and a second control valve. The first control valve controls the flow of cold and hot purified water via a first handle 81, and the second control valve regulates the flow and temperature of tap water via a second handle 82. The faucet body 8 is equipped with or formed with a valve seat that is compatible with the water inlet connector 4. The valve seat is respectively provided with a hot water inlet hole for connecting with the hot purified water, cold purified water, and tap water under the counter, a cold purified water inlet hole, a cold tap water inlet hole, and a hot tap water inlet hole. The hot purified water and cold purified water under the counter can be set to flow out of the hot and cold filters, connected to the cold and hot purified water holes through a hose. The water inlet connector 4 is connected to the water outlet end of the valve seat. The first control valve is used to control the connection and disconnection of hot purified water with the first water inlet 41 and the connection and disconnection of cold purified water with the second water inlet 42. The second control valve is used to control the connection and disconnection of cold and hot tap water with the third water inlet 43. The internal structure of the first control valve and the second control valve is prior art and will not be repeated here. The separate control of purified water and tap water facilitates user distinction and avoids misoperation. A child lock structure may also be provided on the first handle 81 to prevent children from being burned due to misoperation. The child lock structure of the faucet handle is a prior art and will not be described in detail here.

[0051] In an alternative embodiment of the present invention, based on the above-mentioned embodiment, the outer tube 1 is rotatably connected to the faucet body 8. For example, a wear ring 9 is sleeved on the outer tube 1, and a mounting groove is recessed on the outer circumference of the outer tube 1. Positioning features are provided on the inner wall of the wear ring 9 corresponding to the projections in the mounting groove. The mounting groove and the positioning features engage with each other to axially position the outer tube 1. During installation, screws 83 secure the wear ring 9 from the side of the faucet body 8. By applying force to the outer tube 1, the outer tube 1 can rotate 360° circumferentially, facilitating user convenience.
