Jet deflection type special water purifier of water drinking machine

Abstract

The invention relates to a special water clarifier of a turn back flow water fountain, which comprises an upper cover, an upper barrel and a lower barrel. The bottom of the lower barrel is provided with a float valve or a ball cock which can control the water level in a water hopper of the water fountain, the bottom of the upper barrel is provided with an upper filter element which is provided with an exhaust pipe, a lower filter element is arranged under the bottom of the upper barrel, the bottom of the lower filter element is connected with a turn back flow filter element which includes a shell body with a closed bottom, a lower screen is arranged at the lower part in the shell body, an upper screen is arranged at the upper part in the shell body, and granular filter material is filled between the lower screen and the upper screen. The special water clarifier has the beneficial effects that: firstly, the exhaust of the filter element is reliable, gas in the turn back flow filter element needs to be exhausted when the turn back flow is started for the first time only, so the yielding water of the water clarifier is reliable; secondly, the water filtering power of the water clarifier is enough, the lower filter element adopts micropore ceramics with higher filtering precision, so the filtering effect is increased; thirdly, because water flows through the upper filter element, the lower filter element, and the turn back flow filter element for being purified and treated repeatedly, the water quality of the yielding water is ensured more easily.

Description

Technical field [0001] The invention relates to the technical field of drinking water treatment, in particular to a special water purifier for a baffle type water dispenser. Background technique [0002] The water purifier used in conjunction with the water dispenser, that is, the special water purifier for the water dispenser, has gradually been accepted by consumers. This water purifier usually does not have external filtering power, that is, no water pump is provided, and it utilizes the gravity of water itself as the water filtering power, so the water filtering power is very small. In order to have a good filtering effect and effectively filter out pollutants such as sediment, rust, and bacteria in the water, people hope that the filter element has a higher filtering accuracy. However, after the filtration accuracy is improved, it will inevitably lead to an increase in water filtration resistance, a significant decrease in the water filtration flow rate, and the filter...

AI Technical Summary

Problems solved by technology

[0008] 4. Since the filtration accuracy of the siphon filter element (52) and the lower filter element (51) is very low, the water purifier cannot filter out bacteria in the water at all

However, this technology sets the middle bucket, which divides the water filtering power into upper and lower parts. The water pressure in the upper bucket cannot be added to the filter element 2 arranged under the middle bucket. In addition, due to the limitation of the length of the water purifier, As a result, the water filtration power of the upper and lower parts is insufficient, and because the filter elements of the upper and lower parts are equipped with filter materials with high filtration accuracy and great water filtration resistance, the water outlet flow of the water purifier is very small, and many users are concerned about the water outlet flow. Water purifiers that are too small are unacceptable
