The fluid in the runner 2 can contact with the part of the ultraviolet sterilization module 3 to carry out the heat transfer with the ultraviolet sterilization module 3 in order to take away the heat that the ultraviolet sterilization module 3 gived off, reduce the temperature of the ultraviolet sterilization module 3, meanwhile, part ultraviolet sterilization module 3 can contact with the air, and the heat transfer is carried out with the air to the ultraviolet sterilization module 3, in order to take away the heat that the ultraviolet sterilization module 3 gived off, reduces the temperature of the ultraviolet sterilization module 3. Can dispel the heat to ultraviolet sterilization module 3 simultaneously through above-mentioned two kinds of modes, thereby promote the cooling effect ultraviolet sterilization module and can continuously disinfect, in addition, when no fluid flows through in runner 2, ultraviolet sterilization module 3 still can carry out the heat transfer through the air, and then can prevent the damage that ultraviolet sterilization module 3 leads to because of the high temperature.

In order to better understand the water output device of the present application, it will be further explained and illustrated below. As shown in fig. 1 and 5, the water output apparatus may include: the device comprises a shell 1, a water inlet 7, a water outlet 8 and an ultraviolet sterilization module 3. The housing 1 may have a flow channel 2, and the flow channel 2 is used for introducing a fluid such as water. The inlet 7 and the outlet 8 are in communication with the flow channel 2, respectively, so that fluid can flow from the inlet 7 through the flow channel 2 to the outlet 8. The uv sterilization module 3 may be provided to be fitted with the housing 1 so that the uv sterilization module 3 can be mounted on the housing 1. The ultraviolet sterilization module 3 can emit ultraviolet rays for sterilization, and the ultraviolet sterilization module 3 sterilizes the fluid flowing through the flow passage 2 by emitting sterilization light rays to the flow passage 2, thereby reducing the number of colonies of the fluid output from the water output device.

As shown in fig. 1 and 5, a portion of the uv sterilization module 3 can be in contact with the fluid flowing through the fluid passage 2, and a portion of the uv sterilization module 3 is in contact with the air. The uv sterilization module 3 may have opposite first and second ends 31 and 32 and a sidewall. The second end 32 of the ultraviolet sterilization module 3 can emit ultraviolet rays toward the inside of the housing 1 to sterilize the fluid flowing through the flow passage 2, and the first end 31 of the ultraviolet sterilization module 3 is in contact with the air outside the flow passage 2.

As a matter of course, as shown in fig. 1 and 5, a mounting part may be provided on the housing 1, at least a part of the uv sterilization module 3 is disposed at the mounting part, and at least a part of the side wall of the uv sterilization module 3 forms a part of the flow channel 2 with the housing 1. When fluid from ultraviolet sterilization module 3 at least partial lateral wall and casing 1 formation part runner 2, the fluid can contact with ultraviolet sterilization module 3 at least partial lateral wall to carry out the heat transfer with ultraviolet sterilization module 3 at least partial lateral wall and in order to take away the heat that ultraviolet sterilization module 3 gived off, and then reduce ultraviolet sterilization module 3's temperature.

Further, as shown in fig. 1 and 5, the housing 1 may include at least a partial pipe segment, one end of the pipe segment may have an opening 121, at least a portion of the uv sterilization module 3 is disposed at the opening 121, and at least a portion of a side wall of the uv sterilization module 3 and the pipe segment form a partial flow passage 2. Specifically, the mounting portion of the housing 1 may be sleeved outside at least a portion of the side wall of the ultraviolet sterilization module 3, an annular space 4 is formed between the inner side wall of the mounting portion of the housing 1 and the outer side wall of the ultraviolet sterilization module 3, and the flow passage 2 includes a water-cooling flow passage 21 formed by the annular space 4. When the fluid flows through the water-cooling flow channel 21, the fluid cools the ultraviolet sterilization module 3. Because ultraviolet sterilization module 3 sets up in uncovered 121 department, consequently, partial ultraviolet sterilization module 3 can contact with the air, for example, partial ultraviolet sterilization module 3 can contact with the outside air of uncovered 121 of casing 1, like the outside air of casing 1, ultraviolet sterilization module 3 can carry out the heat transfer with the air to take away the heat that ultraviolet sterilization module 3 gived off, reduce ultraviolet sterilization module 3's temperature. In other possible embodiments, the side wall of the housing 1 may have an opening 121, the uv sterilization module 3 may be installed at the opening 121 on the side wall of the housing 1, and the uv sterilization module 3 extends into the flow channel 2 in the housing 1 from the opening 121, so that the side wall of the uv sterilization module 3 can exchange heat with the fluid flowing through the flow channel 2.

As shown in fig. 5, the height of the end of the pipe section near the water inlet 7 is lower than the height of the end of the pipe section far from the water outlet 8. That is, in the pipe section, the height upstream of the pipe section is lower than the height downstream, so that when fluid initially flows into the pipe section, gas in the pipe section will flow downstream of the higher height, so that there is a space for venting gas from the pipe section. In the above embodiment, as shown in fig. 1 and 2, and fig. 5 and 6, the communication hole through which the water inlet 7 communicates with the annular space 4 is located on the inner side wall of the housing 1. Fluid gets into annular space 4 from the intercommunicating pore on the casing 1 inside wall, and fluid can be at least partial circumference flow around ultraviolet sterilization module 3's lateral wall in annular space 4, consequently can improve the relative velocity between fluid and ultraviolet sterilization module 3's lateral wall to promote the heat transfer rate between fluid and ultraviolet sterilization module 3's the lateral wall, and then promote heat transfer effect.

As a possibility, the flow channel 2 may comprise a throttle flow channel 22, as shown in fig. 1 and 5. The ultraviolet sterilization module 3 can emit sterilization light to the throttle channel 22 to sterilize the fluid flowing through the throttle channel 22. The housing 1 has a throttle portion 112 that reduces the cross-sectional area of the throttle flow passage 22 from upstream to downstream, and the throttle portion 112 is located downstream of the uv sterilization module 3.

For example, as shown in fig. 1, the inner diameter of the end of the throttling flow passage 22 close to the uv sterilization module 3 may be larger than the inner diameter of the end far from the uv sterilization module 3. The throttle flow passage 22 may be located downstream of the water-cooling flow passage 21. Fig. 4 is a flow simulation diagram of fluid in the flow channel of the embodiment of the present invention, as shown in fig. 4, when the fluid flows through the throttling flow channel 22, the fluid at different positions in the throttling flow channel 22 with a larger inner diameter flows into the throttling flow channel 22 with a smaller inner diameter due to the throttling effect of the throttling part 112, so as to reduce the dead zone area in the flow channel 2, increase the time of the fluid flowing through the high radiation area of the flow channel 2, and thus improve the radiation amount of the ultraviolet sterilization module 3 to the fluid, thereby improving the sterilization effect. Specifically, as shown in fig. 1, the housing 1 may include a first pipe 11, a throttle flow passage 22 is formed in the first pipe 11, and the ultraviolet sterilization module 3 is disposed at an end of the first pipe 11 to sterilize water flowing through the throttle flow passage 22. The inner diameter of the first section of the first pipe 11 close to the ultraviolet sterilization module 3 is larger than the inner diameter of the second section of the first pipe 11 far away from the ultraviolet sterilization module 3. The first pipe 11 has a throttle portion 112 with a reduced inner diameter between the first section and the second section, and the resistance of the fluid entering the second section of the first pipe 11 can be reduced by the throttle portion 112, and the dead area in the first pipe 11 can be further reduced.

For another example, as shown in fig. 5, the cross section of the end of the throttling flow passage 22 close to the uv sterilization module 3 may be larger than the cross section of the end far from the uv sterilization module 3. The throttling flow passage 22 may be located downstream of the water cooling flow passage 21. The casing 1 can include that first body 11 and cover establish the cover body 12 outside first body 11, and the one end that the ultraviolet sterilization module 3 was kept away from to the cover body is encapsulated situation, and the terminal surface of the one end that ultraviolet sterilization module 3 was kept away from to first body 11 can have a shutoff portion, and the inside wall of shutoff portion can reflect the light of disinfecting equally to improve bactericidal effect. The flow passage 2 may include a throttling flow passage 22 formed in the first tube 11, and a plurality of second openings 1121 are formed in a side wall of an end of the first tube 11 away from the uv sterilization module 3, and the second openings 1121 are circumferentially distributed around an axis of the first tube 11. The throttle 112 may include a second opening 1121. When the fluid flowing through the first tube 11 flows to an end of the first tube 11 away from the uv sterilization module 3, the fluid flows out of the plurality of second openings 1121 on the sidewall of the first tube 11 into the sheath 12, so that the fluid can flow out of the first tube 11 into the sheath 12 through the second openings 1121 at various positions in the circumferential direction, and finally flows out of the water outlet 8. The dead zone area in the first pipe body 11 is reduced in the above manner, so that the time for the fluid to flow through the throttling flow channel 22 is increased, and the irradiation time of the ultraviolet sterilization module 3 on the fluid is prolonged, so as to further improve the sterilization effect. In order to prevent the fluid in the sheath 12 from flowing to the end close to the uv sterilization module 3, as shown in fig. 5, a sealing member such as a gasket may be disposed between the sheath 12 and the first tube 11 at the end far from the uv sterilization module 3. In other possible embodiments, the second opening 1121 may also be located on a blocking portion of an end surface of the first tube 11, so that a certain detouring effect is provided when the fluid in the first tube 11 flows through the second opening 1121 to the water outlet 8, which all can increase the time for the fluid to flow through the throttling flow channel 22, and increase the irradiation time of the fluid by the ultraviolet sterilization module 3, so as to further increase the sterilization effect.

As shown in fig. 1 to 3 and 5 to 7, the housing 1 may include a first tube 11 and a sheath 12 covering the first tube 11, and an opening 121 is formed at an end of the sheath 12. The water inlet 7 can be located on the sleeve body 12, and the water outlet 8 can be located on the first pipe body 11. The flow passage 2 may include a throttle flow passage 22 formed in the first tube 11, the ultraviolet sterilization module 3 is disposed at an opening 121 of the end portion of the sleeve 12 far away from the first tube 11, and the second end 32 of the ultraviolet sterilization module 3 abuts against an end surface of the end portion of the first tube 11. An annular space 4 is formed between the inner side wall of the sleeve body 12 and the outer side wall of the ultraviolet sterilization module 3, and the water inlet 7 is positioned on the sleeve body 12 at the side of the ultraviolet sterilization module 3 and is communicated with the annular space 4. The flow channel 2 comprises a water-cooled flow channel 21 formed by the annular space 4. The side wall of the first tube 11 near the end of the uv sterilization module 3 has a plurality of first openings 111 distributed circumferentially, and the water-cooling flow channel 21 is communicated with the throttling flow channel 22 through the first openings 111. After the fluid flows into the cold water runner 21 from the water inlet 7 to cool the sidewall of the uv sterilization module 3, the fluid flows into the throttle runner 22 in the first pipe 11 through the first opening 111. When the fluid flows into the first tube 11 from the plurality of first openings 111 circumferentially distributed on the side wall of the first tube 11, the fluid flows toward the center of the first tube 11 and rotates to a certain extent, so that the retention time of the fluid in the strongest irradiation area of the uv sterilizing module 3 can be increased, and the sterilizing effect of the uv sterilizing module 3 on the fluid can be greatly improved. Especially when the fluid is bubble water, because there is the bubble in the aquatic, the bubble can change the direction of ultraviolet sterilization light, can reflect even, consequently, bubble rivers can not be better realization bactericidal effect through the ordinary runner 2 that has ultraviolet sterilization light, and above-mentioned structure can be better solve this problem. In other possible manners, the first tube 11 and the sheath 12 may be integrally formed without being separately disposed, so that the number of parts is reduced.

Further, as shown in fig. 1 and 2, 5 and 6, the connection of the water inlet 7 to the annular space 4 may be towards the middle of the annular space 4, or the connection of the water inlet 7 to the annular space 4 may extend substantially tangentially to the annular space 4. In this way, the fluid flowing into the annular space 4 from the water inlet 7 can flow around the annular space 4 to a greater extent, and the amount of the fluid flowing out from the first opening 111 near the communication position is reduced, so that the relative speed between the fluid and the outer side wall of the ultraviolet sterilization module 3 can be further increased, and the heat exchange effect is further improved.

As a practical matter, as shown in fig. 1 and 3, and fig. 5 to 7, the uv sterilizing module 3 may include: a base 33 made of metal, the base 33 having first and second opposing end faces; an LED module 34 capable of emitting ultraviolet rays, provided on a second end face of the base 33; a light-transmitting member 35 disposed between the LED module 34 and the first tube 11; and a sealing sleeve 36 sleeved outside the base 33 and the light-transmitting piece 35. The sealing sleeve 36, the light-transmitting member 35 and the base 33 form a sealed space 37 therebetween, the led assembly 34 is disposed in the sealed space 37, and the first end surface of the base 33 is in contact with air. Further, the LED assembly 34 may include: a circuit board 341 disposed in close contact with the base 33; an LED light 342 mounted on the circuit board 341. A large amount of heat that LED lamp 342 produced passes through circuit board 341 and transmits to the second terminal surface of base 33 on, because the first terminal surface and the air contact of base 33, consequently, base 33 can be used for carrying out the heat transfer with external air, and then realizes the heat dissipation to LED lamp 342.

In order to improve the sealing performance of the sealing space 37 formed between the sealing sleeve 36, the light-transmitting member 35 and the base 33, as shown in fig. 1, a sealing member such as a sealing ring may be provided between the sealing sleeve 36 and the base 33, and a sealing member such as a sealing ring may be provided between the side wall of the light-transmitting member 35 and the sealing sleeve 36.

The sealing sleeve 36 may be made of a material having a high thermal conductivity, such as metal. As shown in fig. 1 and 3, the inner side wall of the sealing sleeve 36 is connected with the outer side wall of the base 33 by screw threads, and the outer side wall of the sealing sleeve 36 and the inner side wall of the jacket body 12 form an annular space 4. A large amount of heat that LED lamp 342 produced passes through circuit board 341 and transmits to the second terminal surface of base 33 on, partial heat can transmit to the gland 36 that the heat conductivity is stronger from the lateral wall of base 33 on, the lateral wall of gland 36 can contact the heat transfer with the fluid in the annular space 4 to reach the heat dissipation purpose, and then realize the heat dissipation to LED lamp 342. For example, the sealing sleeve 36 may be formed from a stainless steel material such that the sealing sleeve 36 does not contaminate the fluid when the fluid contacts the sealing sleeve 36, and further, the fluid, such as water, does not cause the sealing sleeve 36 to rust, corrode, and the like.

In order to ensure that fluid does not leak in the annular space 4 towards the end of the envelope 12, it is possible, as shown in figure 1, to provide a seal, such as a gasket, between the envelope 12 and the gland 36. In order to prevent fluid from leaking between the first pipe 11 and the jacket body 12, a seal member such as a gasket may be provided between the first pipe 11 and the jacket body 12.
