specific Embodiment 1

[0034] The most notable feature of the first embodiment is that a transparent window 5 is provided on one side of the water meter body 9, and a light-emitting device C is fixed outside the transparent window 5, wherein the ultraviolet light source C3 adopts an ultraviolet lamp bead 6 for convective flow through the transparent window 5. The water in the water meter body 9 is sterilized. In this embodiment, the ultraviolet light source C3 has an array of ultraviolet light beads 6, which can emit ultraviolet light and control the light intensity of ultraviolet light. , to sterilize the flowing water. The light output area of ​​the ultraviolet lamp bead 6 is 30mm×70mm in size; the wavelength of ultraviolet light is any wavelength between 190nm and 380nm, or a mixed wave of several wavelengths between 190nm and 380nm, preferably 250-290nm.

Embodiment 2

[0038] In addition, due to some practical applications and appearance requirements, the structure and shape of water meters vary. Moreover, the transparent window can be a plane, a curved surface, or a wavy special-shaped surface. Therefore, the light-emitting surface of the corresponding ultraviolet light source C3 can be a plane, a curved surface, or the surface of other objects with a wave surface. For this, in order to further illustrate the technical scheme described in the present invention, specific embodiment 2 is proposed as follows:

[0039] Such as Figure 4 As shown, a water meter with an ultraviolet sterilizing function whose light-emitting surface of the ultraviolet light source is a curved surface is similar to the water meter in the specific embodiment 1. The metering device A includes a metering plate 1, a water meter body 9, a water inlet 2, The water outlet 3 and the chassis 4 are different in that the transparent window 5 located on the right side wall of ...

Abstract

The invention provides a water meter with ultraviolet sterilization and disinfection functions. The water meter comprises a metering device, an induction device and a light emitting device, wherein a transparent window is formed in a water meter body in the metering device, and an ultraviolet light source of the light emitting device is fixed over against the transparent window and can generate ultraviolet light which passes through the transparent window and sterilizes and disinfects water flowing through the water meter body. While the metering function of an original water meter is ensured, the water flowing through the water meter body is efficiently sterilized and disinfected at high speed.

Description

technical field [0001] The invention relates to the field of semiconductor technology, in particular to a water meter with ultraviolet sterilization function Background technique [0002] In today's world, where approximately 2.2 million people die each year from drinking-water-related diseases, drinking-water quality is a global concern, especially for healthcare. Therefore, the sterilization and disinfection of drinking water is of great significance. Under normal circumstances, the use of chemical methods to sterilize and disinfect often results in complicated processes and easy residues of chemical reagents, while ultrasonic disinfection is often not thorough enough. In contrast, ultraviolet rays have high energy and strong penetrating power. When irradiated on microorganisms or viruses, they can denature the deoxyribonucleic acid (DNA), ribonucleic acid (RNA), proteins, etc. of microorganisms or viruses, thereby achieving The role of sterilization and disinfection. I...
