They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0026] Reference Figure 1 , Figure 2This embodiment discloses a pipeline sterilization device for water used for washing the buttocks of an intelligent toilet, including an inlet pipe 1, an outlet pipe 2, and a transparent pipe 3 for connecting the inlet pipe 1 and the outlet pipe 2. The inlet pipe 1 is connected to a tap water pipe. A water flow sensor 11 is installed on the inlet pipe 1. The position of the water flow sensor 11 can be set according to the actual situation. The water flow sensor 11 is mainly used in conjunction with a control chip, a microcontroller, or even a PLC. The water flow sensor 11 has the functions of accurate flow control, cyclic setting of the operating flow rate, water flow display, and flow accumulation calculation; the outlet pipe 2 adopts a small diameter pipe, and a heater or pressure reducing valve is connected to the end of the outlet pipe 2 away from the transparent pipe 3 to heat or reduce the pressure of the cleaning water; a sleeve 4 is fitted on the transparent pipe 3, and a closed installation cavity is formed between the sleeve 4 and the transparent pipe 3. Multiple ring-shaped ultraviolet germicidal lamps 5 are arranged at intervals in the installation cavity. The number and spacing of the ultraviolet germicidal lamps 5 are set according to the actual situation. The ultraviolet germicidal lamps 5 need to be powered by an external power supply device. Water flows in from the inlet pipe 1, flows through the transparent pipe 3, and finally flows out from the outlet pipe 2. When flowing through the transparent pipe 3, the ultraviolet rays emitted by the ultraviolet germicidal lamps 5 pass through the transparent pipe 3 and effectively sterilize the cleaning water in the transparent pipe 3. Example 2

[0027] Reference Figures 3-5 This embodiment improves upon Embodiment 1 by incorporating a diverter within the transparent tube 3. The diverter includes a diverter column 6 positioned in the middle of the transparent tube 3 and connecting blocks 7 for connecting the diverter column 6 to the inner wall of the transparent tube 3. An annular flow cavity is formed between the diverter column 6 and the inner wall of the transparent tube 3. Multiple connecting blocks 7 are provided, circumferentially spaced within the annular flow cavity. In this embodiment, three connecting blocks 7 are provided, allowing water to pass through the gap between adjacent connecting blocks 7. Both ends of the diverter column 6 are conical, serving a diversion effect.

[0028] Because the ultraviolet germicidal lamp 5 is distributed in a ring around the transparent tube 3 during the sterilization process, the cleaning water in the middle of the transparent tube 3 is farther away from the ultraviolet germicidal lamp 5, and the light penetrating to the middle of the transparent tube 3 is weaker, resulting in poor sterilization effect of the cleaning water in the middle. Therefore, the function of the diverter can make the water flow through the annular flow cavity when it flows through the transparent tube 3, which greatly improves the sterilization effect of the cleaning water. The thickness of the diverter column 6 is set according to the actual situation. A light layer can also be set on the surface of the diverter column 6 to emit ultraviolet light, so that the light is repeatedly reflected and refracted in the annular flow cavity, further improving the sterilization effect of the cleaning water. Example 3

[0029] Reference Figures 6-9This embodiment is an improvement on embodiment 2. A flow-slowing device 8 is further provided inside the transparent tube 3, located on the side of the diversion column 6 near the outlet pipe 2. The flow-slowing device 8 includes a first mounting ring 81 connected to the inner wall of the transparent tube 3, a second mounting ring 82 disposed on the side of the first mounting ring 81 near the outlet pipe 2, and a connecting post 83 for connecting the first mounting ring 81 and the second mounting ring 82. The outer diameter of the second mounting ring 82 is smaller than that of the first mounting ring 81. Multiple connecting posts 83 are provided and are circumferentially spaced. Each connecting post 83 forms a buffer cylinder with the first mounting ring 81 and the second mounting ring 82. In this embodiment, three connecting posts 83 are provided. The second mounting ring 82 is essentially suspended inside the transparent tube 3, and the first... The centers of the mounting ring 81 and the first mounting ring are collinear with the center of the transparent tube 3. The three connecting posts 83 are inclined, making the "diameter" of the buffer cylinder decrease from large to small. An elastic waterproof cover 84 connected to the first mounting ring 81 is fitted on the outer wall of the buffer cylinder. It is mainly made of elastic waterproof fabric. The elastic waterproof cover 84 mainly cooperates with the buffer cylinder to form a "drainage pipe" with a pipe wall. The elastic waterproof cover 84 is slidably connected to each connecting post 83 through a sliding sleeve 85. An adjusting block 9 connected to each sliding sleeve 85 is also provided in the buffer cylinder. An elastic driving device 10 is also provided in the transparent tube 3. The elastic driving device 10 can drive the adjusting block 9 to slide according to the water pressure and water flow rate, thereby driving the elastic waterproof cover 84 to move on the outer wall of the buffer cylinder.

[0030] The elastic drive device 10 includes a sliding cavity 101 disposed in the diversion column 6 and a first spring 102 disposed in the cavity. A portion of the diversion column 6 near the water inlet pipe 1 forms an adjusting column 103. One end of the adjusting column 103 extends into the sliding cavity 101 and can slide within the sliding cavity 101. A transmission rod 104 sleeved in the first spring 102 is also disposed in the sliding cavity 101. One end of the transmission rod 104 is connected to the adjusting column 103, and the other end passes through the diversion column 6 and is connected to the adjusting block 9.

[0031] Since the sterilization effect of the UV germicidal lamp 5 is directly proportional to the UV irradiation time, its sterilization effect is relatively poor under high water pressure and fast water flow. Due to the action of the diversion column 6, the flow velocity of the water flowing through the annular flow cavity increases, or the water pressure or flow velocity of the tap water itself is too high. Therefore, it is necessary to slow down the flow velocity and pressure of the cleaning water to ensure the sterilization effect of the UV germicidal lamp 5. Thus, when the water pressure and flow are too high, they will impact the regulating column 103, causing it to move against the elastic force of the first spring 102. This movement, via the transmission rod 104, drives the regulating block 9, the sliding sleeve 85, and the elastic waterproof cloth towards the outlet. This allows the opening at the end of the elastic waterproof cover 84 to adjust its size as the connecting column 83 moves. The cleaning water flows into the buffer cylinder through the first mounting ring 81 and exits from the opening at the end of the elastic waterproof cover 84. Because the opening diameter decreases, the buffer cylinder slows down the flow of the cleaning water (mainly relying on the elastic waterproof cloth to control the water flow). (Buffering) reduces the flow rate and pressure of the water, thereby reducing the flow rate of the water in the annular flow cavity, and thus prolonging the ultraviolet irradiation time of the water flow, improving and ensuring the sterilization effect of the cleaning water. Similarly, when the water pressure decreases, the adjusting column 103 and the adjusting block 9 will move in opposite directions. The adjusting block 9 includes a support block connected to the transmission rod 104 and multiple elastic telescopic rods 92 circumferentially spaced on the support block. Each elastic telescopic rod 92 is connected to a corresponding sliding sleeve 85. During the movement of the adjusting block 9, the height of the elastic telescopic rod 92 will also be elastically adjusted accordingly. The flow rate and pressure of the cleaning water can be automatically and elastically adjusted through the flow slowing device 8 to ensure the sterilization effect of the ultraviolet germicidal lamp 5. During the movement of the adjusting column 103, the length of the corresponding annular flow cavity will also change, which can also adjust the water pressure and flow to a certain extent. Of course, the adjusting column 103 can also be set to be embedded in the diversion column 6 without affecting the length of the annular flow cavity, depending on the actual needs.
