The housing 1 comprises a first transfer port 11 and a second transfer port 12. The first water transport port 11 and the second water transport port 12 may serve as a water inlet and a water outlet, respectively, of the housing 1. The ports of the first water delivery port 11 and the second water delivery port 12, which are water inlet ports, can be selected according to the needs, and are not particularly limited herein. It is to be understood that each of the first water transport port 11 and the second water transport port 12 described in the following embodiments may be understood as either a water inlet or a water outlet. For example, when the first water transport port 11 is used as a water inlet of the housing 1, the second water transport port 12 is used as a water outlet of the housing 1. Or, when the first water delivery port 11 is used as the water outlet of the shell 1, the second water delivery port 12 is used as the water inlet of the shell 1.

It should be noted that the shape, structure, size and arrangement positions of the first water delivery port 11 and the second water delivery port 12 of the housing 1 may be selected and adjusted according to the need, and are not limited specifically herein. The housing 1 is mainly used for accommodating water to be flowed into a water-using apparatus.

And the inside of the case 1 can be prevented from being corroded by the electrochemical protection of the water passing net 22.

The electron cathode 23 can be directly connected with the water passing net 22, can also be connected with the water passing net 22 through a conductor, and can also be connected with the water passing net 22 through an aqueous medium. The specific implementation manner is selected and adjusted as required, as long as the scale deposited on the electron anode 21 can be adsorbed by the water passing network 22.

In one example, the electron cathode 23 is a conductive sheet.

In one example, an anode lead-out portion connected to the electron anode 21 and a cathode lead-out portion connected to the electron cathode 23 are further included. The anode lead-out and cathode lead-out are used for connection to a power supply to supply power to the electron anode 21 and the electron cathode 23.

Is provided in the housing 1 for sterilizing water flowing through the housing 1. The germicidal assembly 5 includes a germicidal lamp 51, the germicidal lamp 51 being inserted in the housing 1.

The germicidal lamp 51 may be any germicidal lamp 51 structure known in the art, and is not limited in any way. The method can be used for destroying DNA base pairs of bacteria in water when water is irradiated, so that bacterial cells lose replication and reproduction capacity and even die. For example, the germicidal lamp 51 may be an ultraviolet lamp or a mercury lamp.

In the case where the germicidal lamp 51 employs an ultraviolet lamp, the wavelength of the ultraviolet light emitted by the ultraviolet lamp is in the range of 200nm to 275 nm. Ultraviolet light within this wavelength range can effectively kill bacteria in water.

In this embodiment, because the scale inhibiting component 2 and the sterilizing component 5 are arranged in the housing 1 at the same time, the water flowing through the housing 1 can be sterilized and descaled at the same time.

The light shield 6 is used for preventing the light of the germicidal lamp 51 from irradiating the cup body 14 outside the light shield 6, thereby preventing the cup body 14 from being corroded by the long-term irradiation of the cup body 14, and preventing the light from being absorbed by the external environment to reduce the germicidal intensity of the light.

In one example, the light shield 6 includes a cylinder and an opaque reflective layer provided on an inner wall surface of the cylinder. The opaque reflective layer is used to block the germicidal light emitted from the germicidal lamp 51 from irradiating the inner sidewall of the housing 1 or being absorbed by the inner sidewall of the housing 1. And the light-tight reflecting layer can reflect the sterilizing light irradiated on the light-tight reflecting layer, so that the reflected sterilizing light can sterilize and disinfect the water flowing through the annular flow passage again. Through repeated reflection of the sterilization light, an optical field with extremely strong intensity can be formed in the annular flow channel, and the sterilization efficiency and the sterilization quality of the liquid are effectively improved.

The specific material of the opaque reflective layer may be selected and adjusted depending on the type of germicidal light rays of the germicidal lamp 51. For example, in the case where the germicidal light is ultraviolet light, the opaque reflective layer may be made of an aluminum foil material. The light-tight reflecting layer can be a coating formed on the inner side wall of the cylinder body, and can also be a thin structure coated on the inner side wall of the cylinder body.

In one embodiment, a light-transmitting cover 7 is disposed in the light-shielding cover 6, the light-transmitting cover 7 covers the exterior of the germicidal lamp 51, and an annular flow passage is formed between the exterior of the light-transmitting cover 7 and the inner side wall of the light-shielding cover 6. The light-transmitting tube is used for isolating the germicidal lamp 51 from the inner cavity of the cup body 14, so that the germicidal lamp 51 is prevented from being damaged due to the fact that water flowing into the cup body 14 directly contacts with the germicidal lamp 51, and secondary pollution to the water after the germicidal lamp 51 contacts with the water is avoided.

In one example, the light-transmissive tube may be made of any material that is non-reflective and non-absorbing. For example, quartz glass may be used. Quartz glass is made by melting various pure natural quartz (such as crystal, quartz sand, etc.). The linear expansion coefficient is extremely small, is 1/10-1/20 of common glass, and has good thermal shock resistance. The heat resistance of the material is very high, the frequent use temperature is 1100-1200 ℃, and the short-term use temperature can reach 1400 ℃. It has a high spectral transmission. The quartz glass is an amorphous material with a single silicon dioxide component, the microstructure of the quartz glass is a simple network consisting of silicon dioxide four-sided structural body structural units, and the quartz glass has unique performance due to the large Si-O chemical bond energy and the compact structure, particularly has excellent optical performance of transparent quartz glass, and has excellent transmittance in the continuous wavelength range from ultraviolet radiation to infrared radiation.
