Description

Technical Field

[0001] The utility model belongs to the technical field of water purification equipment, and particularly relates to a drinking water purification equipment. Background Art

[0002] Direct drinking water refers to the purified water that uses domestic drinking water or water meeting the sanitary standards of domestic drinking water as the water source, and removes impurities and harmful substances in the water by using a variety of purification techniques and can be directly drunk. This process is of great significance for protecting public health and preventing waterborne diseases. Common purification techniques include precipitation, filtration, reverse osmosis, disinfection, ion exchange, and distillation, etc. In the precipitation process, flocculants are added to make impurities coagulate and precipitate. Filtration removes particulate matter and microorganisms through physical media such as sand filters or activated carbon. Reverse osmosis technology relies on pressure to drive water molecules through a semi-permeable membrane to intercept dissolved solids, and disinfection generally uses chlorine or ozone, etc. to kill bacteria and viruses. Ion exchange is used to remove hardness components and heavy metals in water, and distillation is to obtain pure water by heating, evaporating and then condensing. The drinking water purification process needs to be customized according to the raw water quality and water use requirements, and at the same time, regular water quality testing is carried out to ensure the purification effect and ensure the safety and health of drinking water. With the progress of technology, new purification techniques and equipment are constantly developing, providing higher-quality drinking water for humans.

[0003] In the prior art, if the efficiency and cost of drinking water are the main considerations, usually the form of filtration is adopted to purify drinking water, so that the water is filtered through a filter element and then exported for people to drink. However, although real-time filtration can filter some impurities directly during drinking, the microorganisms among them cannot be completely filtered by the filter element, so it is difficult to ensure the cleanliness of drinking water.

[0039] Preferably, the sterilization device uses an ultraviolet lamp. Ultraviolet rays are emitted by the ultraviolet lamp to sterilize the filtered water. The ultraviolet lamp has the advantages of being easily obtained and having a relatively low cost, which is more conducive to wide promotion.

[0040] Preferably, light-shielding strips are arranged on the outer sides of both the water storage tank 2 and the cover 20. Since ultraviolet lamps are used for disinfection treatment, further, the outer sides of the water storage tank 2 and the cover 20 are made light-tight by the light-shielding strips, so that the ultraviolet irradiation of the ultraviolet lamp mainly acts on the water storage tank 2 and the cover 20, thereby enabling the filtered water to achieve the best sterilization effect. Among them, both the water storage tank 2 and the cover 20 are made of non-transparent materials, and in this embodiment, food-grade stainless steel is specifically used.

[0041] Preferably, such asFigure 2 , Figure 3 , Figure 4 , Figure 5 As shown in Figure 5 , the water circulation structure 4 includes a first water pump 41, a pipe joint 42, a lower hollow connecting seat 43, a second water pump 44, a drinking water pipe 45, a four-way ball valve 46, a water diversion pipe 47, an upper hollow connecting seat 48, and a water inlet pipe 49.

[0042] The first water pump 41 is connected to the lower hollow connecting seat 43 through an L-shaped pipe joint 42; the second water pump 44 is connected to the water outlet pipe 10 through the drinking water pipe 45; the four-way ball valve 46 has four openings. The first opening is connected to the water storage tank 2 through a vertical pipe, the second opening is connected to the second water pump 44 through a horizontal pipe, the third opening is connected to the first water pump 41 through the water diversion pipe 47, the fourth opening is connected to the upper hollow connecting seat 48, and the filtering component 3 is arranged between the upper hollow connecting seat 48 and the lower hollow connecting seat 43 and is respectively connected to the upper hollow connecting seat 48 and the lower hollow connecting seat 43. The connection between the four-way ball valve 46 and the upper hollow connecting seat 48 is connected to the water inlet pipe 49.

[0043] Preferably, the filtering component 3 includes a filter element 30 and a connecting pipe.

[0045] Preferably, the filter element 30 is a ceramic filter element. Since the ceramic filter element can retain beneficial minerals in water, such as calcium, magnesium, etc. during the filtering process, and these minerals are beneficial to human health, the ceramic filter element is widely used in industries such as water purifiers, barreled water, and quality-separated water supply.

[0046] Preferably, the machine shell 1 includes a base 11, a peripheral shell 12, and a top shell 13. The peripheral shell 12 is arranged around the base 11 along the outer side of the upper surface of the base 11; the water circulation structure 4 is arranged inside the peripheral shell 12; the top shell 13 is arranged on the peripheral shell 12, and the water storage tank 2 is fixedly connected to the top shell 13.
