Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a water purification device capable of filtering water with sterilization, decolorization, and deodorization. This water purifier eliminates the harmful effects on the human body and the main body of the water purifier by sterilizing the water and then supplying ozone that does not cause secondary pollution and filtering it to sterilize pathogenic bacteria.

[Conventional technology and its challenges] In recent years, the quality of tap water has decreased significantly due to industrial pollution.
For example, it may contain organic substances such as phthalate esters, or may contain excessive amounts of ions such as alkaline earth metals. For this reason, not only does it have an adverse effect on health, but the taste of drinking water is significantly reduced.

In addition, water used for drinking purposes may contain not only E. coli but also infectious bacteria such as bacteria that cause epidemic diarrhea, Vibrio cholerae, and Salmonella typhoid fever. There is a strong demand for the removal of such organic matter and bacteria.

However, in Jubei's water purifiers, devices using activated carbon are connected directly to the water tap to remove impurities and substances that generate unpleasant odors from the tap water, or devices packed with ion exchange resin are used. There are water filtration devices that soften water during filtration using activated carbon, and water purification devices that filter water using reverse osmosis, etc., but water purification devices that use activated carbon are used as disinfectants in tap water. As it adsorbs chlorine and loses its sterilizing effect, it warps inside the water purification device and causes bacteria to multiply.
This has the disadvantage that the bacteria can be mixed into the water that is to be filtered again, and water purifiers that use ion exchange resins only remove ions from the water, but cannot remove bacteria or non-ionic impurities. As with devices that use activated carbon, there is a risk that bacteria and the like will grow inside the water purification device and be re-mixed into the water that is to be filtered.

If you try to filter water using a water purification device that uses activated carbon or a packed tower filled with ion exchange resin as described above, you will need a pump, etc., so you cannot get filtered water anywhere, which is inconvenient. There was a point.

[Purpose of the Invention] The present invention has been made by fully taking into consideration the various problems of the conventional art as described above. To provide a water purification device which can not only suppress the propagation of pathogenic bacteria by using ozone gas which does not cause chlorine, but can also remove chlorine, other odors, colors, etc.

[Means for Solving the Problems] In order to achieve the above object, the water purification device of the present invention is a water purification device that receives water from a drinking water supply means and removes and filters various contaminants in the water. , a water purifier main body receives water from the water supply hose of the drinking water supply means and passes it through a water purification filter and an activated carbon layer to remove foreign substances; an ozone gas generating means that mixes the ozone gas generated by an ozone gas generating electrode disposed in a high-voltage transformer with the bubbles and discharges the gas, and an ozone gas generating means disposed on the output side of the ozone gas generating means to prevent backflow of water. The present invention is characterized by comprising a check knob means for preventing ozone gas from being supplied in only one direction.

Further, the water purification device of the present invention is a water purification device that receives water supply from a drinking water supply means and removes various pollutants.
A water purifier body receives water supplied from the drinking water supply means and passes it through a water purification filter and an activated carbon layer to remove foreign substances, and a bubble generator compresses air sucked in from the outside to generate air bubbles. an ozone gas generating means that mixes the ozone gas generated by an ozone gas generating electrode disposed in a high-pressure transformer with air bubbles and discharges the ozone gas, one end of which is connected to the filtering means, and the other end of which is connected to the ozone gas generating means.
