[0029] See also Figure 1 and Figure 2 The embodiment of the present disclosure provides a dynamic water sterilization device, including an illumination unit 10 and a driving unit 20. The illumination unit 10 is used to provide ultraviolet light to sterilize the water flowing through. The driving unit 20 and the illumination unit 10 are separately arranged, and the two are electrically connected through a wire 31.

[0030] See also Figure 2 In this embodiment, the illumination unit 10 includes a water inlet body 11 and an ultraviolet light emitting element 12. The water inlet body 11 includes a housing 111. The housing 111 is provided with a sterilization chamber 101 and an installation chamber 102 separated from each other. The sterilization chamber 101 is used for water flow to pass through, and the installation chamber 102 is used for installing the ultraviolet light emitting element 12. The sterilization chamber 101 is provided with a light-transmitting area, and the light of the ultraviolet light emitting element 12 enters the sterilization chamber 101 through the light-transmitting area.

[0031] Furthermore, the sterilization chamber 101 is constructed by a light-transmitting tube 112 with openings at both ends, and the tube wall of the light-transmitting tube 112 is partially or completely transparent to form a light-transmitting area. The ultraviolet light-emitting element 12 is arranged on the peripheral side of the light-transmitting tube 112. Specifically, the light-transmitting tube 112 is a quartz glass tube, and the ultraviolet light-emitting element 12 is arranged on the upper side of the quartz glass tube. The use of a quartz glass tube can effectively improve the transmittance of ultraviolet light and improve the ultraviolet sterilization effect.

[0032] It is understandable that in other embodiments, an ultraviolet light emitting element 12 may be provided on the lower side of the light-transmitting tube 112, or an ultraviolet light emitting element 12 may be provided on both the upper and lower sides of the light-transmitting tube 112. One or more ultraviolet light emitting elements 12 may be provided, and this embodiment does not impose any specific limitation.

[0033] The ultraviolet light emitting element 12 includes a lamp board 121 and ultraviolet lamp beads 122 disposed on the lamp board 121. Specifically, the lamp board 121 is an LED board, and only ultraviolet lamp beads 122 are disposed on the LED board, without other electronic components. At least one ultraviolet lamp bead 122 is disposed, and the more ultraviolet lamp beads 122 there are, the better the sterilization effect. In this embodiment, at least two ultraviolet lamp beads 122 are disposed to ensure the sterilization effect.

[0034] Furthermore, the LED pin positions of the lamp board 121 are all wrapped with a sealant layer 123, and the light-emitting surface of the ultraviolet lamp bead 122 is exposed outside the sealant layer 123. Specifically, the outer surface of the lamp board 121 is wrapped with a sealant layer 123, and only the light-emitting surface of the ultraviolet lamp bead 122 is exposed to the outside, so as to form a sealing effect for the ultraviolet light-emitting element 12, and avoid adverse consequences such as leakage caused by water leakage or moisture.

[0035] Furthermore, a water inlet pipe 114 and a water outlet pipe 115 are respectively provided at both ends of the shell 111 of the water inlet body 11, and the water flows into the sterilization chamber 101 through the water inlet pipe 114, and then flows out through the water outlet pipe 115. The light-transmitting tube 112 is arranged between the water inlet pipe 114 and the water outlet pipe 115, and is sealed with the water inlet pipe 114 and the water outlet pipe 115 through a sealing member, so that the installation chamber 102 forms a sealed chamber. The sealing member is provided with a water passage connecting the water inlet body 11 and the light-transmitting tube 112, and the flow cross-sectional area of ​​the water passage is smaller than the flow cross-sectional area of ​​the light-transmitting tube 112, so as to increase the residence time of the water flow in the sterilization chamber 101 and improve the sterilization efficiency. In one embodiment, the sealing member is a sealing ring 113, and a sealing ring 113 is provided at both ends of the light-transmitting tube 112. The sealing ring 113 seals the pipe opening of the light-transmitting tube 112 around. Specifically, the sealing ring 113 can be, for example, a silicone pad. By providing a sealing ring 113 at the tube opening of the light-transmitting tube 112 , the installation cavity 102 can be formed into a sealed cavity, thereby preventing water from entering the installation cavity 102 and causing damage to the ultraviolet light-emitting element 12 .

[0036] The driving unit 20 includes a housing 21 and a driving circuit board 22 disposed in the housing 21, and the driving circuit board 22 is electrically connected to the ultraviolet light emitting element 12 through a wire 31. The driving circuit board 22 is used to control the current operation of the ultraviolet light emitting element 12. The driving circuit board 22 can be selected according to the parameters of the ultraviolet light emitting element 12, and this embodiment does not specifically limit it.

[0037] Furthermore, one end of the housing 21 has an opening to allow the driver circuit board 22 to be installed. After the driver circuit board 22 is installed, it is sealed by glue filling, so that the driver circuit board 22 is wrapped with a glue filling layer 23, and the wire 31 passes through the glue filling layer 23 and is connected to the ultraviolet light-emitting element 12. Through the glue filling operation, the driver circuit board 22 is sealed in the housing 21, and all components of the driver circuit board 22 except the wire 31 are wrapped by the sealant to achieve a good waterproof protection effect. Similarly, the other end of the wire 31 passes through the sealant layer 123 of the light board 121 and is connected to the light board 121.

[0038] This embodiment also provides a smart toilet, including a toilet seat (not shown), a toilet cover body (not shown) and the above-mentioned dynamic water sterilization device. The illumination unit 10 and the driving unit 20 of the dynamic water sterilization device can be arranged on the toilet cover body, for example, on the toilet cover plate or toilet gasket.

[0039] See also Figure 1 The toilet seat body is also provided with a water inlet control valve 30, a water supply pipeline 40 and a spray bar assembly 50. The water inlet control valve 30 is arranged at the water inlet end of the water supply pipeline 40, and the spray bar assembly 50 is arranged at the water outlet end of the water supply pipeline 40. The water inlet control valve 30 is used to control the water supply of the water supply pipeline 40, and the spray bar assembly 50 is used to spray water to achieve the function of washing human body parts. The water inlet control valve 30 and the spray bar assembly 50 are both prior art and will not be described in detail here.

[0040] Specifically, in this embodiment, the illumination unit 10 is disposed on the water supply pipeline 40 and is arranged between the water inlet control valve 30 and the spray bar assembly 50, and the water flow of the water supply pipeline 40 flows through the sterilization chamber. That is, the water inlet pipe 114 of the illumination unit 10 is connected to the water outlet end of the water inlet control valve 30, and the water outlet pipe 115 is connected to the water inlet end of the spray bar assembly 50. The water flow from the water inlet control valve 30 passes through the illumination unit 10 for ultraviolet light sterilization and then enters the spray bar assembly 50. The drive unit 20 is arranged away from the water supply pipeline 40, for example, by lengthening the length of the wire 31, so that the drive unit 20 is installed at a position far away from the water supply pipeline 40.

[0041] Furthermore, a reversing valve 60 and / or a heating assembly (not shown) are also provided on the water supply pipeline 40. The reversing valve 60 is arranged between the illumination unit 10 and the spray bar assembly 50. The spray bar assembly 50 has a plurality of water inlets, and different water inlets are adapted to different human body cleaning parts. The reversing valve 60 has a plurality of water outlets adapted to the spray bar assembly 50, and the water inlet of the spray bar assembly 50 is connected to the water outlet of the reversing valve 60 through different pipelines, and the water inlet switching of the spray bar assembly 50 is realized through the reversing valve 60, thereby realizing the switching of the spray bar assembly 50 to clean different human body parts.

[0042] Furthermore, the heating component is disposed between the illumination unit 10 and the spray bar assembly 50. The water flow can be heated by the heating component to improve the comfort of washing the human body parts. It should be noted that in other embodiments, the heating component can also be disposed between the water inlet control valve 30 and the illumination unit 10. That is, the water flow can be sterilized first and then heated, or the water flow can be heated first and then sterilized.

[0043] Furthermore, a control module 70 is also provided on the toilet seat body. The control module may be, for example, a control chip. The control module may be connected to the water inlet control valve 30, the reversing valve 60 and other components through wires to achieve control of each component. In this embodiment, the drive unit 20 is connected to the control module 70 through a wire 32, and the ultraviolet irradiation time is controlled by the control module 70.

[0044] Furthermore, an overcurrent protection module is also provided on the driver circuit board 22, and the overcurrent protection module is used to interrupt the circuit when the current exceeds a preset current. Specifically, the overcurrent protection module is set as a fuse, and when the current exceeds the preset current, the fuse blows, thereby effectively preventing the driver circuit board 22 and even the entire control module 70 from being damaged.

[0045] Furthermore, the control module 70 is also used to control the driving circuit board 22 to start the ultraviolet light emitting element 12 when the spray bar assembly 50 is working. Through this setting, the water flowing through is sterilized and disinfected only when the human body part cleaning function is turned on, avoiding energy waste.

[0046] Furthermore, the length of the water path from the water inlet of the illumination unit 10 to the water outlet of the water inlet control valve 30 is greater than or equal to 150 mm, and the length of the water path from the water outlet of the illumination unit 10 to the water inlet of the spray bar assembly 50 is greater than or equal to 150 mm. By controlling the length of the water path from the illumination unit 10 to the water inlet control valve 30 and the spray bar assembly 50, the illumination unit 10 can maintain a sufficient distance from the water inlet and outlet that can be touched by the user. When the illumination unit 10 has a risk of leakage, the user's safety is ensured by the long-distance water path resistance.
