As shown in fig. 3, the bottom of the light-transmitting cover 3 has an opening, the bottom of the light-transmitting cover 3 is tightly attached to the bottom surface of the inside of the water storage box 2, the light-transmitting cover 3 and the local inner wall of the water storage box 2 surround to form an accommodating cavity 31, a water storage interlayer 21 is formed between the outer wall of the light-transmitting cover 3 and the inner wall of the water storage box 2, and the bottom and the top of the water storage box 2 are respectively provided with a water inlet 22 and a water outlet 23 communicated with the water storage interlayer 21. Wherein, the aperture of the water inlet 22 and the water outlet 23 and the aperture of the water storage interlayer 21 can be arranged in proportion, thereby adjusting the water inlet and outlet flow rate of the water storage box 2.

The water outlet pipe 4 is connected above the water storage box 2. In this embodiment, as shown in fig. 2, the water outlet pipe 4 includes a straight line section 41 and a curved section 42 connected to each other, the straight line section 41 is vertically arranged, and a bottom end port of the straight line section 41 serves as a water inlet end of the water outlet pipe 4 and is communicated with the water outlet 23 of the water storage box 2; the bent section 42 is in an inverted U shape, a first end port of the bent section 42 is communicated with a top end port of the straight section 41, and a second end port of the bent section 42 is used as a water outlet end of the water outlet pipe 4 and is communicated with the outside atmosphere and faces to the inner cavity of the water tank 1. Due to the presence of the curved section 42, in the non-operating state, a large amount of water is stored inside the outlet pipe 4, the residual water level of which is shown by the dashed line in fig. 2.

The disinfection lamp tube 5 is accommodated in the accommodating cavity 31 and arranged towards the water outlet 23, and can generate disinfection light and act on the water body flowing through the water storage interlayer 21. Specifically, as shown in fig. 3, the disinfection lamp 5 is in an inverted U shape, the central axis of the disinfection lamp 5 coincides with the central axis of the straight line section 41, two ends of the disinfection lamp 5 are respectively installed on the bottom surface inside the water storage box 2 through two lamp holders 51, and the lamp holders 51 are lower than the installation table 11.

In this embodiment, the disinfection lamp 5 is a pulse lamp capable of generating a pulse flash with a wavelength of 200-1100 nm, and is used for efficiently disinfecting the disinfection cavity 121. The action mechanism of the pulse flash sterilization is the synergistic action of all wave bands in a spectral range, and is mainly embodied in three aspects:

(1) photochemical reaction in ultraviolet band: when the microorganism is irradiated by ultraviolet light in the pulsed intense light spectrum, thymine and cytosine in nucleic acid substances (DNA and RNA) generate photochemical reaction to generate dimers, so that the nucleic acid substances of the microorganism are damaged);

(2) flash heating effect: when per cm²When the peak power of the area reaches more than 1000W, the microorganisms are heated>At 100 ℃, because the flash irradiation time is extremely short, microorganisms can not be cooled normally, so that cell walls are broken and melted to die;

(3) pulse effect: the penetration of the intense pulsed light and the transient high energy mechanical impact damage the cell walls and other cellular components, resulting in bacterial death.

In addition, the outlet pipe disinfection structure is also provided with a controller, and the switch button 12 and the lamp holder 51 are electrically connected with the controller, so that the controller can receive signals of the switch button 12 and disinfect the on and off of the lamp tube 5.

The working principle of the utility model is as follows: when the water outlet pipe 3 needs to be disinfected, the switch button 12 is started, the controller receives a signal of the switch button 12 and starts the disinfection lamp tube 5, an external water source (such as purified water filtered by a water purifier) enters the water storage interlayer 21 through the water inlet 22, the disinfection lamp tube 5 simultaneously generates stroboflash to disinfect water flowing through the water storage interlayer 21, water flows along the straight line section 41 and the bent section 42 sequentially through the water outlet 23, by utilizing the total reflection characteristic of light (the fact that light can be transmitted along the bent water flow in experiments by British physics Houndsand Dall in 1870) and the instantaneous high-efficiency sterilization technology of pulse flash, the pulse flash can be transmitted along the bent water flow, and accordingly, all bacteria bred in the water outlet pipe 4 are instantly killed;

recording the distance from the residual water level line to the water outlet end of the water outlet pipe 4 for the initial water flow to flow through as L, recording the flow time as t, setting the frequency of pulse stroboflash in the period of time as 2Hz, and quickly killing bacteria entering the inner wall of the water outlet pipe 4 and at the residual water level line by air through flash illumination; after the time t, setting the frequency of pulse stroboflash to be 1Hz, and disinfecting the water introduced from the water inlet 22;

in addition, in the flowing process of the water body, on one hand, the water flow can take away the heat released by the disinfection lamp tube 5 through the stroboscopic effect, so that the service life of the disinfection lamp tube 5 can be prolonged; on the other hand, the heat that disinfection fluorescent tube 5 released can also heat or cold-proof water storage interlayer 21's water, and the final water that discharges from outlet pipe 4 need not additionally heat again, and more the person of facilitating the use promotes and uses the experience.
