In figure, ladder shape sterilizes channel 1, water inlet 2, water outlet 3, flow sensor 4, control circuit 5, power supply 6, shell 7, distributive pipe road 8, collecting conduit 9, branch pipe(tube) 10, ultraviolet LED sterilization module 11.
Specific embodiment
Below according to attached drawing and preferred embodiment the present invention is described in detail, the objects and effects of the present invention will become brighter White, below in conjunction with drawings and examples, the present invention will be described in further detail.It should be appreciated that described herein specific Embodiment is only used to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of effective UV LED sterilizing unit, which includes shell 7 and setting Ladder shape in shell 7 sterilizes channel 1, flow sensor 4, control circuit 5, power supply 6, ultraviolet LED sterilization module 11, ladder It includes that distributive pipe road 8, collecting conduit 9 and at least three branch pipe(tube)s 10, distributive pipe road 8 are parallel with collecting conduit 9 that shape, which sterilizes channel 1, Setting, all branch pipe(tube)s 10 are arranged in parallel, and each branch pipe(tube) 10 is vertical with distributive pipe road 8, collecting conduit 9 and head and the tail both ends are distinguished It is connected with distributive pipe road 8 and collecting conduit 9, the both ends in distributive pipe road 8, collecting conduit 9 and each branch pipe(tube) 10 are respectively provided with purple Water inlet 2 and water outlet 3 is respectively set in the lengthwise centers position of outer LED sterilization module 11, distributive pipe road 8 and collecting conduit 9.For The unimpeded ability of water flow is improved, the diameter in distributive pipe road 8, collecting conduit 9 and each branch pipe(tube) 10 is greater than the diameter of water inlet 2;For Germicidal efficiency is improved, ultraviolet LED sterilization module 11 is made of optically focused mould group and ultraviolet LED sterilization mould group, and ultraviolet LED sterilizes mould group It is made of more ultraviolet LEDs, ultraviolet LED sterilization module 11 generates the parallel ultraviolet light irradiation-sterilize of column, and distributive pipe road 8 catchments The direction for the parallel ultraviolet light of column that pipeline 9 and 10 both ends ultraviolet LED sterilization module 11 of each branch pipe(tube) generate respectively with divide water Pipeline 8, collecting conduit 9 are parallel with the water (flow) direction in each branch pipe(tube) 10.Control circuit 5, power supply 6 are enclosed in shell 7, And power supply 6 is electrically connected with flow sensor 4, ultraviolet LED sterilization module 11, control circuit 5, is powered for it, flow sensor 4 It is also electrically connected with control circuit 5 with ultraviolet LED sterilization module 11;Flow sensor 4 is set to each 10 inlet of branch pipe(tube), uses Water velocity in detection 10 inlet of branch pipe(tube), and speed signal is passed into control circuit 5, control circuit 5 is according to water flow Speed signal determines best irradiation power, and best irradiation power signal is passed to each 10 both ends of branch pipe(tube) by conducting wire Ultraviolet LED sterilization module 11 realizes efficient sterilizing.
A kind of effective UV LED method for disinfection, which comprises the steps of:
(1) water flow flows into ladder shape by water inlet 2 and sterilizes channel 1, flows into each after distributive pipe road 8 is shunted Pipeline 10;
(2) flow sensor 4 for being set to each 10 inlet of branch pipe(tube) detects water velocity in each branch pipe(tube) 10, And speed signal is passed into control circuit 5;
(3) control circuit 5 determines the best irradiation power of each branch pipe(tube) 10 according to water velocity, and will most preferably irradiate function Rate signal passes to the ultraviolet LED sterilization module 11 for being set to each 10 both ends of branch pipe(tube) by conducting wire, according to best irradiation function Rate carries out ultraviolet sterilization;
