Description

Household pure water machine water storage unit

technical field

The utility model relates to a household pure water machine, in particular to a water storage unit in the household pure water machine.

Background technique

With the development of the economy, the situation of water resources has deteriorated in many places. The shortage and pollution of water resources have become more and more serious, and the problem of drinking water safety for urban residents has become prominent. Aiming at the secondary pollution of tap water in cities and the persistent presence of harmful substances in tap water due to source water pollution, more and more household water purifiers with reverse osmosis membrane as the core filter unit have entered thousands of households. The existing household pure water machine uses the reverse osmosis membrane as the core filter unit. After multi-stage pretreatment and pressurization of tap water, it enters the reverse osmosis membrane unit. The pure water produced can fully meet the domestic drinking water requirements of developed countries. standard.

Household water purifiers are all equipped with a water storage unit. The function of the water storage unit is to store the pure water obtained by reverse osmosis filtration, and the other is to provide a certain water pressure when people take the pure water to transfer the pure water from the water storage. Press out in the unit. In the existing domestic pure water machine, the water storage unit mainly includes a pressure barrel, and an inflatable capsule is fixed on the inner wall of the pressure barrel. Air compressed air chamber, the pressure barrel is provided with inlet and outlet for pure water to enter and exit the water purification chamber, and the water storage unit provides water outlet water pressure by the compressed air acting on the inflatable capsule. The water storage unit of this structure has the following disadvantages. During use, it needs to be inflated to maintain pressure, and the pressure tank has certain safety hazards; the inflatable capsule will rupture after a certain period of use, and the existence of the compressed air cavity makes it very cumbersome to replace the inflatable capsule; Inflatable capsules are mostly made of rubber materials, which tends to cause peculiar smell in the pure water in the early stage of use, and the service life is also short.

Utility model content

The technical problem to be solved by the utility model is to provide a water storage unit of a household pure water machine. The water storage unit does not need to be inflated to maintain pressure during the use of the pure water machine, so that the water storage tank is safer and the daily maintenance is easier. .

The technical solution adopted by the utility model to solve the technical problem is: the water storage unit of the household pure water machine of the utility model includes a box body with an internal cavity, and a flexible diaphragm connected to the body is arranged in the box body. The diaphragm separates the internal cavity into a water storage chamber and a water pressure chamber, and the box body is provided with a clean water inlet and outlet communicating with the water storage chamber and a water inlet and outlet communicating with the pressure water chamber.

After adopting the above technical measures, the water outlet pressure of the purified water is provided by the pressure water source, and the control operation is simplified. Because there is no need to configure the compressed air chamber, the air inflation and pressure maintenance during the use of the pure water machine are eliminated, making the water storage tank safer. Moreover, the replacement of the flexible diaphragm and the daily maintenance of the household pure water machine are very simple.

As a preferred solution of the present utility model, in order to facilitate manufacture and daily maintenance, the box body is composed of a screwed bottom shell and an upper cover, and the periphery of the flexible diaphragm is pressed and fixed on the upper port of the bottom shell by the upper cover position.

As a further optimization of the above preferred solution, in order to simplify the system structure of the domestic water purifier as much as possible, the water inlet and outlet are connected to the water pipeline before the water inlet of the internal booster pump of the domestic water purifier through pipelines.

The beneficial effect of the utility model is that the water outlet pressure of the purified water is provided by the pressure water source, which eliminates the need to inflate and maintain the pressure during the use of the pure water machine, making the water storage tank safer, and the replacement of the flexible diaphragm and the daily maintenance of the household pure water machine are very simple ; Since the space occupied by the flexible diaphragm is much smaller than that of the inflatable capsule, the water storage utilization rate of the box body is greatly improved.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural schematic diagram of the utility model household pure water machine.

Components, part names and corresponding marks in the figure: box body 10, bottom shell 11, upper cover 12, pure water inlet and outlet 13, water storage chamber 14, pressurized water chamber 15, water inlet and outlet 16, flexible diaphragm 20.

Detailed ways

Referring to FIG. 1 , the water storage unit of the household water purifier of the present invention includes a box body 10 with an internal cavity. The box body 10 is provided with a flexible diaphragm 20 connected to its body. The flexible diaphragm 20 separates the inner cavity into a water storage chamber 14 and a pressurized water chamber 15. The box body 10 is provided with a The clean water inlet and outlet 13, the water inlet and outlet 16 communicated with the pressurized water chamber 15. Since the water outlet pressure of the purified water is provided by the pressure water source, the inflation and pressure maintenance during use can be avoided, making the water storage tank safer. Since the space occupied by the flexible membrane 20 is much smaller than that of the inflatable capsule, the water storage utilization rate of the box body 10 is greatly improved.

For the convenience of manufacture and daily maintenance, as a typical configuration, referring to FIG. 1 , the box body 10 is composed of a screwed bottom shell 11 and an upper cover 12, and the periphery of the flexible diaphragm 20 is pressed by the upper cover 12. It is fixed on the upper port of the bottom case 11. The clean water inlet and outlet 13 is arranged on the upper cover 12 , and the water inlet and outlet 16 is arranged on the bottom or the side wall of the bottom shell 11 .

In order to avoid odor in the pure water at the initial stage of use and improve the service life, the flexible diaphragm 20 can preferably be made of food-grade silicone material. In order to simplify the system structure of the domestic water purifier as much as possible, the water inlet and outlet 16 can be connected with the water pipeline before the water inlet of the booster pump inside the domestic water purifier through a pipeline, and a pressure limiting valve is set on the pipeline. When the water storage chamber 14 is filled with water, the pipeline is depressurized, and the pressurized water in the water pressure chamber 15 flows out from the water inlet and outlet 16 . When water is discharged from the water storage chamber 14, pressurized water is filled into the pressurized water chamber 15 through the pipeline.
