Problems solved by technology
[0003] Existing filter devices for drinking water filters mainly use activated carbon to absorb impurities, but activated carbon can only be used to filter pollutants in water, decolorize, filter and purify liquids, gases and some heavy metals, but has no bactericidal effect
In reality, once the activated carbon is used for a period of time, the adsorbed substances and the activated carbon itself will retain some microorganisms and bacteria. Since most of the current drinking water filters have no bactericidal effect, these bacteria and microorganisms will eventually enter people's bodies with drinking water. inside the body, causing health problems in people

Embodiment 1
[0037] Embodiment 1, the thickness of the sponge layer is 2cm, and the content of 3mm in the spherical activated carbon is more than 96%, and the balance is other diameters. In this example, after the TDS pen test (used to test water quality, the smaller the value, the better the water quality), the TDS value of the filtered drinking water is 55ppm.
Embodiment 2
[0038] Embodiment 2, the thickness of the sponge layer is 2cm, and the content of 7mm in the spherical activated carbon is more than 96%, and the balance is other diameters. In this example, after the TDS pen test, the TDS value of the filtered drinking water is 67ppm.
Embodiment 3
[0039] Embodiment 3, the thickness of the sponge layer is 2cm, and the content of diameter of 11mm in the spherical activated carbon is more than 96%, and the balance is other diameters. In this example, after the TDS pen test, the TDS value of the filtered drinking water is 75ppm.

Abstract
The invention discloses a bactericidal drinking water filtering device which comprises a filtering material and a hollow shell, wherein the shell is internally provided with an ultraviolet radiation device; a water inlet is formed in the middle of the top of the shell; a water inlet filtering net is arranged between the water inlet and the filtering material in a partitioning manner; a water outlet is formed in the middle of the bottom of the shell; a water outlet filtering net is arranged between the water outlet and the filtering material in the partitioning manner; the ultraviolet radiationdevice comprises a power supply, a water sensor, a switch circuit and LED (Light Emitting Diode) ultraviolet lamp beads; the LED ultraviolet lamp beads are connected with the power supply through theswitch circuit; the LED ultraviolet lamp beads are sealed in quartz tubes; the output signal line of the water sensor is connected with the switch triggering end of the switch circuit; the water sensor is supplied with power from the power supply; the shell is connected with a water proof cavity; the power supply and the switch circuit are arranged in the water proof cavity; the water sensor is positioned below the water inlet filtering net; and the quartz tubes are buried in the filtering material. The filtering device has ultraviolet sterilization, and meanwhile, the energy consumption of the device is reduced.
Description
technical field [0001] The invention relates to the technical field of drinking water treatment, in particular to a drinking water filtering and sterilizing device. Background technique [0002] According to the survey of the World Health Organization, 80% of the diseases in the world are caused by drinking polluted water. According to experts, at present, there are many cases of diseases caused by unsafe drinking water every year in our country, and the economic losses caused have reached 1% of the GDP of the year. [0003] The filter device of the existing drinking water filter mainly uses activated carbon to absorb impurities, but activated carbon can only be used to filter pollutants in water, decolorize, filter and purify liquids, gases and some heavy metals, but has no bactericidal effect. In reality, once the activated carbon is used for a period of time, the adsorbed substances and the activated carbon itself will retain some microorganisms and bacteria. Since most ...
