Then, there may be microorganisms in natural water sources, especially pathogenic microorganisms, which have the characteristics of high infection risk, low harmful dose, short effective time, and high degree of harm. Therefore, natural water sources are often not directly drinkable. Microbes are inactivated, but people are in the wild and cannot carry heavy disinfection equipment, and the safety of drinking water is often difficult to guarantee

Embodiment 1

[0026] like Figure 1-7 As shown, the sterilizing filter cup provided by the present invention includes a cup body 1 and a cup cover 2 fastened to the cup body; the cup body 1 includes an upper cup body 11 and a lower cup body 12 that are detachably connected from top to bottom, preferably Threaded connection; the upper cup body 11 is a closed structure, the interior of which is separated from the chamber A111 and the chamber B112 by the partition plate 13, the top of the upper cup body is provided with a water inlet 113 that communicates with the chamber A, and the chamber A is horizontally fixed with Electrode filter membrane 3, electrode filter membrane 3 is formed by laminating porous anode 31, porous electrode separator 32 and porous cathode 33; a power source 4 is provided in chamber B, and the positive electrode and negative electrode of power source 4 are connected to the porous electrode through wires respectively. The anode 31 is connected to the porous cathode 33, t...

Embodiment 2

[0043] Utilize the method for any one of the sterilized filter cups in embodiment 1 to sterilize, comprising the following steps:

[0044] (1) Set the porous anode, the porous electrode separator, and the porous cathode sequentially from top to bottom, so that the voltage of each electrode filter membrane is 2-3V, and set the power supply on the outer wall corresponding to the upper cup body and chamber B. Connected power switch 6 and indicator light 7;

[0045] (2) Remove the lower cup, fill it with water to be sterilized, and connect it to the upper cup;

[0046] (3) Turn on the power switch, and after confirming that the indicator light is on, turn the entire disinfection filter cup upside down, and the water contained in the lower cup will first contact the porous cathode of the electrode filter membrane under its own gravity, and an electrode reaction will occur to generate hydroxide ions , and then contact the porous anode to kill microorganisms in the water under alkal...

Abstract

The invention discloses a disinfecting filtering cup and a disinfecting method thereof. The disinfecting filtering cup comprises a cup body and a cup cover covered on the cup body; the cup body is composed of an upper cup body and a lower cup body which are interconnected with each other from top to bottom; the interior of the upper cup body is separated into a chamber A and a chamber B by a separating plate; a water guiding port connected with the chamber A is formed on the top of the upper cup body; an electrode filtering membrane is horizontally fixed in the chamber A; the electrode filtering membrane comprises a porous cathode, a porous electrode interlayer and a porous anode which are overlapped; a power supply is arranged in the chamber B; the porous cathode and the porous anode arerespectively connected with a cathode and an anode of the power supply through wires; a wire hole, through which the wire can pass, is formed on the separating plate; a water draining hole which is connected with the chamber A is formed on the bottom of the upper cup body; the porous cathode and the porous anode are both made from a conductive material; the porous electrode interlayer is made froman insulating material. According to the invention, no chemical reagent is added, only extremely low voltage is required for realizing high-standard disinfection, disinfecting effect is high and no disinfecting by-product is generated.

Description

technical field [0001] The invention relates to the field of fluid disinfection, in particular to a disinfection filter cup. Background technique [0002] In the process of survival practice in the wild, or in the event of sudden geological disasters, it is very important to ensure the safe supply of drinking water. Then, there may be microorganisms in natural water sources, especially pathogenic microorganisms, which have the characteristics of high infection risk, low harmful dose, short effective time, and large degree of harm. Therefore, natural water sources are often not directly drinkable. Microorganisms are inactivated, but people in the wild cannot carry heavy disinfection equipment in Mandarin, and the safety of drinking water is often difficult to guarantee. [0003] Therefore, the design of a portable field disinfection filter cup is of great significance in ensuring the safe disinfection of drinking water in emergency situations.
