Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The following provides a term explanation of the present application.

UVC: the wavelength of the ultraviolet light is 100-280nm, but the wavelength below 200 nm is vacuum ultraviolet light, so that the ultraviolet light can be absorbed by air, and the wavelength of the UVC can penetrate through the atmosphere is 200-280nm.

UVC-LED: namely a deep ultraviolet light emitting diode. Similar to the traditional white light LED, the LED emits invisible deep ultraviolet light, and the light with the wavelength can destroy the DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) molecular structure of microorganisms, so that bacteria die or cannot reproduce, thereby achieving the aim of sterilization. UVC-LEDs are a novel type of artificial deep ultraviolet light source.

UVC-LED overflows formula sterilization water injection well choke: namely, a device for instantaneously sterilizing the flowing water by using a UVC-LED as a light source. The water to be disinfected enters from the water inlet, is sterilized in the device by ultraviolet irradiation, then flows out from the water outlet, and the water flow is kept flowing in the device continuously. The advantages are that the sterilization process is very short (second sterilization), the water can not be heated, and toxic and harmful substances can not be introduced, and the sterilization device can be applied to the scenes of household water purification faucet, direct drinking machine, industrial water sterilization, tap water sterilization and the like.

For the convenience of understanding the technical solutions provided in the embodiments of the present application by those skilled in the art, the following description will explain related technologies:

the inventor knows that the sterilizing water nozzle using the UVC-LED as the light source has large volume and limitations in application and appearance. And a UVC-LED sterilization water nozzle is used for treating water flow with the flow rate of 2LPM, and the sterilization rate of escherichia coli reaches 99.99%, so that the sterilization cavity length reaches phi 18 multiplied by 120mm, and the sterilization cavity cannot be arranged at the positions of a nozzle, the water nozzle and the like due to the excessive length. Specifically: (1) the sterilizer is oversized and has too long length. A main sterilization cavity is formed by a reflecting cylinder and a large-angle luminous UVC-LED (120 DEG), wherein the UVC-LEDs are distributed on the side face of the reflecting cylinder, the reflecting cylinder needs to be of a certain length in order to fully utilize the illumination of the UVC-LEDs, and meanwhile, the diameter of the reflecting cylinder cannot be too small in order to ensure water flow, so that the volume is overlarge and the length is too long. Taking a module with water treatment capacity of 0.8LPM and E.coli sterilization rate of 99.99% as an example, the length of the reflecting cylinder reaches phi 18 multiplied by 120mm, and the reflecting cylinder can not be applied to small spaces such as nozzles, water nozzles and the like. (2) The ultraviolet shielding structure is absent. The use scene of the sterilizing water nozzle is that the sterilizing water nozzle is arranged outside the water dispenser to replace the original faucet structure, so that the sterilizing water nozzle has requirements on the leakage amount of ultraviolet light, otherwise, the sterilizing water nozzle may cause damage to human bodies. The inventor knows that the ultraviolet leakage amount can not reach national standard no matter the light source is arranged on the side surface or the bottom surface of the reflecting cylinder.

Therefore, the embodiment of the application provides a novel scheme of the UVC-LED sterilizing water nozzle, and the sterilizing cavity is reduced to phi 15 multiplied by 24mm under the same water treatment effect. The total volume and the length of the sterilizing tap are obviously reduced, so that the sterilizing tap can be applied to the terminal water outlets of nozzles, taps and the like, and the popularization speed of products can be greatly improved. Specifically: (1) the UVC-LED sterilizing water nozzle of the scheme is small in size and short in length. The main sterilization cavity is formed by the reflecting cylinder and the UVC-LEDs (30-35 DEG) which emit light at a small angle, and the UVC-LEDs are distributed on the bottom surface of the reflecting cylinder. The scheme has the advantages that the illumination is concentrated, the illumination intensity is high, and the length of the reflecting cylinder can be shortened. Taking a module with water treatment capacity of 2LPM and colibacillus sterilization rate of 99.99% as an example, the size is reduced to phi 15 multiplied by 24mm (the length is shortened to 24mm from 120 mm), and the water treatment device can meet the application occasions of small spaces such as nozzles, water nozzles and the like. (2) The scheme has an ultraviolet shielding structure. And a guide vane structure is added above the reflecting cylinder, and the effects of guiding flow and preventing ultraviolet leakage are achieved. The measured ultraviolet leakage can be far lower than the national standard threshold (only about 10% of the national standard threshold).

Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In the above-described alternative embodiment, the heat of the light source plate 9 is conducted to the lower surface of the heat sink 10, and the water flow flowing in from the water inlet 1106 directly hits the lower surface of the heat sink 10, so that the heat of the light source plate 9 can be rapidly taken away.
