Technical Field

The invention belongs to the technical field of household water purifiers, and particularly relates to a cylinder type integrated water purifier.

Background

Water is a source of life, and the quality of drinking water is closely related to the health of people. World health organization (WTO) surveys indicate that 80% of disease and 50% of childhood death worldwide are associated with poor drinking water quality. One quarter of the population in China is drinking water which does not meet the sanitary standard, and water pollution is the most important water environment problem in China.

Through propaganda and popularization of drinking water and health knowledge for many years, people gradually know the influence of drinking water quality on human health, and attach more importance to drinking water safety, so that a great market prospect is provided for the application of water purifier products. The household water purifier is used in 95% of families in developed European and American countries, and the household use rate is less than 5% in China, so that the water purifier has a wide development space in China.

The applicant has invented a double-outlet cylinder type integrated water purifier, and the Chinese patent application number is 201910278968.3. The water purifier can produce pure water and pure water to meet various water demands of users for eating and not eating. However, the double-outlet cylinder type integrated water purifier needs to mix the waste water and the pure water for generating the pure water, so that the pure water in the water storage cylinder is also discharged when the pure water is discharged.

Disclosure of Invention

As further shown in fig. 6, the housing assembly 20 includes a barrel 21 and a cap 22. The barrel 21 and the barrel cover 22 are both made of plastic, and the barrel cover 22 covers the upper port of the barrel 21 to form a filter cartridge.

The primary filter element 901 is composed of PP cotton and a carbon rod, wherein the PP cotton can filter out sediment, oxidized substances and suspended solids in water, and the carbon rod can remove chlorine and peculiar smell in water. The reverse osmosis filter element 32 can further filter out bacteria, viruses and heavy metals in the water, and finally pure water is obtained.

The double-outlet barrel type integrated water purifier provided by the invention has the following working modes:

the raw water inlet 121 is connected to a tap water pipe, and in connection with fig. 17, two pure water outlets 122 of the pure water outlet flow passage 132 are connected to the pure water pipe 81 of the water storage tub and the double water outlet tap 80, respectively, the waste water outlet 123 is connected to a waste water pipe, and the pure water outlet 124 is connected to the pure water pipe 82 of the double water outlet tap 80. A waste water proportional control valve is arranged in the waste water pipe.

In the case where both the pure water valve 83 and the clean water valve 84 of the double outlet water 80 are closed. Initially, raw water (i.e., tap water or other unfiltered water) enters the raw water inlet channel 131, the raw water insertion cavity 117, and the raw water insertion tube 209 from the raw water inlet 121. The raw water of the raw water insertion pipe 209 is divided into two paths in the waterway cover plate, one path can flow into the filter cartridge through the first raw water plate inner channel 503, the first water inlet 502, the first upper half cavity, the first water outlet 504 and the raw water inlet cavity 230, and the other path can flow into the filter cartridge through the second raw water plate inner channel 503', the second water inlet 502', the second upper half cavity, the second water outlet 504' and the raw water inlet cavity 230. After being filtered by the filter element assembly, the water flowing into the filter cartridge flows into the purified water outlet flow channel, when the pressure in the purified water outlet flow channel is increased, the second control valve 300' is driven to cut off the second water control flow channel section, raw water is automatically closed from the second water control flow channel section to enter the cartridge, and the manufacture of purified water is automatically stopped; when the pure water in the water storage barrel is fully stored, the water pressure in the pure water outlet channel 132 is increased, the first control valve 300 is driven to cut off the first water control channel section, raw water is automatically closed to enter the barrel from the first water control channel section, and the production of the pure water is automatically stopped.

When pure water is required, the pure water valve 83 in the double water outlet 80 is opened (at this time the pure water valve 84 is closed). Because the water purge valve 84 is closed, the water pressure in the water purge outlet passage 134 is still relatively high, and the second control valve 300' is kept actuated to shut off the second water control passage segment. And as the pure water valve 84 is opened, the water pressure in the pure water outlet channel 132 is reduced along with the consumption of pure water in the water storage barrel, and the first control valve 300 is released, so that the first water control channel section is unobstructed, and raw water can enter the barrel through the first water inlet 502 through the water control channel section. Raw water entering the barrel enters the primary filter element from the side surface through a gap between the barrel body 21 and the primary filter element 901, enters the central cavity after primary filtration, then enters the reverse osmosis filter element 32 from the upper end surface of the reverse osmosis filter element 32, namely the water inlet end surface, and after filtration, part of the raw water enters the pure water production pipe 907 and flows into the water storage barrel through the pure water through cavity 221, the pure water check valve cavity 111, the pure water outlet flow channel 132 and the pure water outlet 122 to obtain pure water. The waste water is discharged into the waste water cavity 222, and the waste water is not discharged from the second discharge port 205 due to the large water pressure in the purified water outlet flow passage 134, but only discharged to the sewer through the second discharge port 207, the waste water plug tube 208, the waste water plug cavity 116, the waste water outlet flow passage 133 and the waste water outlet 123. When the pure water valve 83 is closed, the water pressure in the pure water outlet channel 132 rises along with the full of pure water in the water storage barrel, and then the first control valve 300 is driven to cut off the first water control channel segment, so that the raw water is prevented from entering, and automatic water control is realized.

When water purification is needed, the water purification valve 84 in the double water outlet 80 is opened (at this time, the water purification valve 83 is closed), and the water pressure in the water purification outlet channel 132 is large because the water purification valve 83 is closed, so that the first control valve 300 is driven to cut off the first water control channel section.

And as the water purifying valve 84 is opened, the water pressure in the water purifying outlet channel 134 is low, the second control valve 300 'is released, the second water controlling channel section is unobstructed, and raw water can enter the barrel through the second water controlling channel section through the second water inlet hole 502'. Raw water entering the barrel enters the primary filter element from the side from a gap between the barrel 21 and the primary filter element 901, and enters the central cavity after primary filtration, and at the moment, the water pressure in the pure water outlet flow channel is high, the water pressure in the pure water outlet flow channel 134 is low, and water entering the central cavity does not permeate through a reverse osmosis membrane to flow into a water production pipe, but directly flows to a waste water end through the surface of the reverse osmosis membrane, is discharged to the pure water outlet flow channel 134 from the first water outlet 205, and finally purified water is directly obtained from the double-water outlet tap. Since the waste water proportional control valve is provided in the waste pipe 82, since the waste water proportional control valve has a large resistance to water, even if a part of waste water is discharged from the second discharge port into the waste pipe, it is very small. When the water purifying valve 84 is closed, the water pressure in the purified water outlet channel 134 will increase, and the second control valve 300' is driven to cut off the second water control channel segment, so as to prevent raw water from entering, and automatic water control is performed.

As can be seen from the above detailed description, the present invention has the following advantages:

the barrel-type integrated water purifier realizes independent production of pure water and purified water, the production of purified water does not need to mix waste water and pure water, and pure water in the water storage barrel cannot be discharged by placing purified water. The purified water is directly obtained by flowing out of the surface of the reverse osmosis membrane after being filtered by the primary filter element, so that the flow is relatively large, on one hand, the reverse osmosis membrane can be flushed, on the other hand, the reverse osmosis membrane is not used, the loss of the reverse osmosis membrane is reduced, the service life of the reverse osmosis membrane is prolonged, even if the purified water is discharged from a waste water flow channel in the process of preparing the purified water, the purified water is discharged in a very small amount due to the existence of the waste water proportion regulating valve, and the water resource is saved.

Therefore, the cylinder type integrated water purifier has the advantages of being capable of manufacturing pure water and pure water independently, large in water yield, capable of flushing a reverse osmosis membrane while manufacturing the pure water, beneficial to prolonging the service life of the reverse osmosis membrane, saving water resources and the like.

Of course, if the reverse osmosis filter element of the water purifier of the present invention adopts a large flow reverse osmosis filter element, such as a 1000 gallon large flow reverse osmosis filter element, the water storage barrel can be omitted, and only the water outlet 122 connected with the water storage barrel is blocked.

However, it will be appreciated by persons skilled in the art that the above embodiments are provided for illustration of the invention and not for limitation thereof, and that changes and modifications to the above described embodiments are intended to fall within the scope of the appended claims as long as they fall within the true spirit of the invention.
