[0038] As shown in Figure 1 and Figure 2 , the over-flow type water purification outlet structure of the embodiment includes a pipeline body 10, the pipeline body 10 is provided with a water inlet 11, a disinfection port 12 and a water outlet 13 which are communicated with each other; the water inlet 11 is used for connecting a water inlet pipeline, the disinfection port 12 is provided with an ultraviolet lamp assembly 20, and the pipeline body 10 is provided with a photocatalyst assembly 30 for sterilization under the action of ultraviolet rays in the pipeline between the disinfection port 12 and the water outlet 13. It should be noted that the ultraviolet lamp assembly 20 includes an ultraviolet lamp holder 25, the ultraviolet lamp holder 25 is sequentially provided with a second waterproof sealing piece 23, a heat dissipation block 24, an ultraviolet lamp unit 22 and a first waterproof sealing piece 21; wherein the first waterproof sealing piece 21 is in the form of a ring structure, which is sleeved outside the lamp bead of the ultraviolet lamp unit 22 to prevent water from flowing out of the pipeline body 10; at the same time, the heat dissipation block 24, the ultraviolet lamp unit 22 and the first waterproof sealing piece 21 are all installed in the second waterproof sealing piece 23, so that the heat dissipation block 24, the ultraviolet lamp unit 22 and the first waterproof sealing piece 21 are respectively sealed from both sides by the first waterproof sealing piece 21 and the second waterproof sealing piece 23, thereby improving the sealing performance of the ultraviolet lamp assembly 20 as a whole.

[0039] Specifically, after the water in the water inlet pipeline flows into the pipeline body 10 from the water inlet 11, the ultraviolet light emitted by the ultraviolet lamp assembly 20 and the photocatalyst assembly 30 have a photocatalytic reaction, have a strong catalytic degradation function, can disinfect the water flowing in the pipeline body 10, can effectively degrade the toxic and harmful gases in the water, and can effectively kill a variety of bacteria; and the structure disinfects the water in the process of flowing, so that the ultraviolet light and the photocatalyst assembly 30 can fully disinfect the water, avoid the bacteria in the water from being discharged from the water outlet or adhering to the pipeline body 10, thereby avoiding the reproduction of bacteria in the pipeline body, ensuring the quality of the water when it finally flows out, improving the direct drinking experience of users, and maintaining the health of users.

[0040] In a specific embodiment, as Figure 2As shown, the pipeline body 10 includes a first pipeline 14 and a second pipeline 15 in communication, the first pipeline 14 is in communication with the disinfection port 12 and the water outlet 13 respectively, and the second pipeline 15 is in communication with the water inlet 11 and the second pipeline 15 respectively. The photocatalyst assembly 30 includes a photocatalyst pipe unit 31, the inner wall of the first pipeline 14 is provided with a mounting limiting portion, the shape of the mounting limiting portion matches the shape of the photocatalyst pipe unit 31, and one end of the mounting limiting portion is provided with a first mounting table 141 for anti-disengagement limiting, and one end of the photocatalyst pipe unit 31 abuts against the first mounting table 141. Among them, the mounting limiting portion refers to the disinfection pipeline of the inner wall of the first pipeline 14, and the photocatalyst pipe unit 31 is arranged in the disinfection pipeline. It should be noted that the photocatalyst assembly 30 has water permeability, and water can pass through the photocatalyst pipe unit 31.

[0041] It should be understood that through the arrangement, the water flows from the water inlet 11 and enters the first pipeline 14, and the ultraviolet lamp assembly 20 can illuminate the entire first pipeline 14, so that the disinfection efficiency is improved; more specifically, for example, after the water flows into the first pipeline 14, the water will gradually overflow the first pipeline 14 and then be discharged from the water outlet 13, in the process, the water is flowing and can be continuously illuminated by the ultraviolet lamp assembly 20, and under the cooperation of the photocatalyst assembly 30, the disinfection efficiency is greatly improved. In other alternative embodiments, the positions of the disinfection port 12 and the water inlet 11 can be exchanged, so that the first pipeline 14 communicates the water inlet 11 and the water outlet 13, and the second pipeline 15 communicates the first pipeline 14 and the disinfection port 12.

[0042] Further, as shown in Figure 2 and Figure 3 The first mounting table 141 further extends in the direction away from the disinfection port 12 to provide a second mounting table 142, and the photocatalyst assembly 30 further includes a photocatalyst support assembly 32 and a first photocatalyst sheet 33. The photocatalyst support assembly 32 is arranged in the photocatalyst pipe unit 31, the first photocatalyst sheet 33 is arranged between the first pipeline 14 and the water outlet 13, the pipe edge of the first pipeline 14 abuts against the first photocatalyst sheet 33, and the projection of the photocatalyst support assembly 32 and the photocatalyst pipe unit 31 along the extension direction of the first pipeline 14 all falls into the first photocatalyst sheet 33.

[0043] It should be understood that through the arrangement of the photocatalyst support assembly 32, the photocatalyst pipe unit 31 can be supported, so that the photocatalyst pipe unit 31 can be close to the connection between the second pipeline 15 and the first pipeline 14, to ensure that all the water flowing out of the second pipeline 15 can pass through the photocatalyst pipe unit 31, and the photocatalyst support assembly 32 arranged in the photocatalyst pipe unit 31 can further react with the ultraviolet lamp assembly 20 to further disinfect the water.

[0044] It is necessary to supplement that the first mounting table 141 is also provided with a blocking wall part, which plays a limiting role for the photocatalyst pipe unit 31.

[0045] Further, as shown in Figure 3 and Figure 4 , the photocatalyst support assembly 32 comprises a photocatalyst support unit 321, a second photocatalyst sheet 322 and a third photocatalyst sheet 323; the second photocatalyst sheet 322 abuts against the second mounting table 142; the two sides of the third photocatalyst sheet 323 are respectively provided with a photocatalyst support unit 321; one of the photocatalyst support units 321 respectively abuts against the second photocatalyst sheet 322 and the third photocatalyst sheet 323, and the other photocatalyst support unit 321 respectively abuts against the third photocatalyst sheet 323 and the first photocatalyst sheet 33; that is, the third photocatalyst sheet 323 abuts against one photocatalyst support unit 321 between the second photocatalyst sheet 322, and the third photocatalyst sheet 323 abuts against another photocatalyst support unit 321 away from the second photocatalyst sheet 322; the other photocatalyst support unit 321 abuts against the first photocatalyst sheet 33. Through the arrangement of the second photocatalyst sheet 322 and the third photocatalyst sheet 323, the two adjacent photocatalyst support units 321 are separated, which avoids the direct contact between the two photocatalyst support units 321 and the possibility of misalignment, provides support for the photocatalyst support unit 321 above, improves the integrity of the photocatalyst support assembly 32, and the additional photocatalyst sheet can also increase the sterilization effect. It is necessary to supplement that the photocatalyst support assembly 32 can also correspondingly increase the number of photocatalyst support units 321 and three photocatalyst sheets 323 according to the photocatalyst pipe unit 31.

[0046] Further, the photocatalyst support unit 321 comprises a photocatalyst support base 3211 matched with the shape of the second photocatalyst sheet 322; the photocatalyst support base 3211 is provided with a through hole 3212; the through hole 3212 is arranged so that the staff can use a tweezers clamp to clamp the hole wall of the through hole 3212 when assembling the photocatalyst assembly 30, thereby installing it in the photocatalyst pipe unit 31, making the whole installation more simple and stable. The photocatalyst support base 3211 extends in the direction of the third photocatalyst sheet 323 and is provided with a photocatalyst support support column 3213, which abuts against the inner wall of the photocatalyst pipe unit 31. Through the arrangement of the photocatalyst support support column 3213, the photocatalyst support unit 321 and the photocatalyst sheet combination can completely support the photocatalyst pipe unit 31, ensure that the photocatalyst pipe unit 31 is attached to the wall of the first pipe 14, and effectively reduce the bacterial growth at the pipe wall.

[0047] In a specific embodiment, as shown in Figure 3 and Figure 4As shown, the two photocatalyst support units 321 are mirror-symmetrically arranged about the third photocatalyst sheet 323. The photocatalyst support columns 3213 on both sides of the third photocatalyst sheet 323 support the third photocatalyst sheet 323, so that the pressure on both sides of the third photocatalyst sheet 323 is balanced, thereby improving the overall service life.

[0048] Further, the pipeline body 10 further comprises a third pipeline 16, which is in communication with the first pipeline 14, and the third pipeline 16 is arranged on one side of the first pipeline 14 close to the water outlet 13, and the pipe opening of the third pipeline 16 away from the first pipeline 14 is the water outlet 13; the inner wall of the third pipeline 16 is provided with an internal thread part, and the third pipeline 16 is threadedly connected with a connector seat 40 through the internal thread part, the connector seat 40 is provided with a mounting hole, and a connector assembly 50 for connecting a water outlet unit is sleeved in the mounting hole, wherein the water outlet unit includes a water outlet faucet, a water outlet filter and other structures for the end, and water is supplied to the user. Specifically, the connector assembly 50 includes a connector compression ring 51, a connector clasp ring 52, a stainless steel ring 53, a steel ring buckle 54 and a sealing ring 55, and the sealing ring 55, the steel ring buckle 54, the stainless steel ring 53, the connector clasp ring 52 and the connector compression ring 51 are sequentially pressed on the connector seat 40.

[0049] In the embodiment, the outer contour of the photocatalyst tube unit 31 is square, and the inner contour of the first pipeline 14 is square. Because the contour is square, it plays a limiting role on the photocatalyst tube unit 31, so it is not easy to rotate, and at the same time, the photocatalyst tube unit 31 has a plane to butt joint the connection between the second pipeline 15 and the first pipeline 14, effectively avoiding the situation that water flows away from the gap between the photocatalyst tube unit 31 and the pipe wall of the first pipeline 14, ensuring the sterilization effect.

[0050] In the embodiment, the photocatalyst assembly 30 includes a titanium base, and a titanium dioxide layer is formed on the titanium base by oxidation. Through the above arrangement, the titanium dioxide is not easy to fall off, preventing the situation that the powder falls off and dissolves in water, improving the overall safety and service life.

[0051] In summary, the over-flow type water purification outlet structure provided in the embodiment can complete sterilization and disinfection at positions such as between the water purification tank and the water outlet, provide users with a good direct drinking experience, and has the advantages of high safety, long service life, stable structure, compact structure, strong sealing performance and the like.
