[0002] With the improvement of the quality of life, water safety has become more and more of a concern for the people, and the use of water purifiers has become more and more common. At the same time, with the increase in customer demand, the water flow requirements for household water purifiers are also increasing.

[0003] Existing water purifiers have the following disadvantages:

[0004] A. Using a high-flux membrane to increase the water flow rate will result in a significant increase in cost and an increase in the size of the water purifier.

[0005] B. Use a small flux membrane to achieve a large water flow through an air-driven or water-driven water storage device. These solutions require a large space for water or gas, resulting in a significant reduction in water storage capacity, which cannot meet customer needs.

[0006] C. Use a small flux membrane to extract clean water from the water storage device through a separate water pump to achieve a large water flow rate. This solution has disadvantages in cost, waterway complexity, and volume due to the addition of a separate water pump. Summary of the invention

[0007] In view of the above problems existing in the existing water purifiers, the present invention aims to provide a water purifier system with a simple structure, low cost and small size and dual functions of one pump.

[0008] The specific technical solutions are as follows:

[0010] It also includes a driving motor, which is respectively connected to the booster pump and the water pump for driving the booster pump and the water pump to work.

[0011] As a further improvement and optimization of the present solution, the driving motor is a dual-output shaft motor, and one output shaft of the dual-output shaft motor is transmission-connected to the booster pump, and the other output shaft is transmission-connected to the water pump.

[0012] As a further improvement and optimization of this solution, the two output shafts of the drive motor are respectively located on both sides of the drive motor.

[0013] As a further improvement and optimization of this solution, a branch is also connected between the pipeline between the filter element and the water storage tank and the pipeline between the booster pump and the post-filter element, and a pressure-bearing one-way valve is also provided on the branch.

[0014] As a further improvement and optimization of this solution, a concentrated water solenoid valve is also connected to the filter element.

[0015] As a further improvement and optimization of this solution, a one-way valve is also connected to the pipeline between the water pump and the post-filter element.

[0016] As a further improvement and optimization of this solution, a pressure switch is also connected to the pipeline between the post-filter element and the water outlet faucet.

[0017] As a further improvement and optimization of this solution, a water level controller is also provided on the water storage tank, and the water level controller is electrically connected to the drive motor and the inlet solenoid valve respectively.

[0018] The positive effects of the above technical solution compared with the prior art are as follows:

[0019] (1) In the present invention, a drive motor is used to drive the booster pump and the water pump to work simultaneously, so as to realize the dual functions of increasing the pressure of the filter element and pumping water from the water storage tank, meeting the large-flow water outlet effect of using a small-flux membrane, with low cost, simple water circuit and small volume.

[0020] (2) In the present invention, in order to avoid the water outlet of the water pump being blocked and the water inside the pump cavity circulating repeatedly to generate heat, a branch is also connected between the pipeline between the filter element and the water storage tank and the pipeline between the booster pump and the post-filter element, and a pressure-bearing one-way valve is also provided on the branch. By presetting the conduction pressure of the pressure-bearing one-way valve, it is ensured that when the faucet is opened to discharge water, the pressure-bearing one-way valve does not conduct, and when the faucet is closed, the pressure-bearing one-way valve conducts, so that the water pumped by the water pump flows back to the water storage tank through the branch.

Figure 2 This is a schematic diagram of the connection of the driving motor, booster pump, and water pump of a dual-purpose water purifier system of the utility model. Figure 1-2 As shown, a preferred embodiment of a one-pump dual-purpose water purifier system is shown, comprising: a water inlet solenoid valve 1, a pre-filter element 2, a booster pump 3, a filter element 4, a water storage tank 5, a water pump 6, a post-filter element 8 and a water outlet faucet 10 connected in sequence by a clearance pipeline; and also comprising a drive motor 15, which is respectively connected to the booster pump 3 and the water pump 6 for driving the booster pump 3 and the water pump 6 to work.

[0028] In this embodiment, municipal tap water enters through the water inlet solenoid valve 1, passes through the pre-filter element 2, is pressurized by the booster pump 3 and enters the filter element 4, the clean water enters the water storage tank 5, the water pump 6 pumps out the clean water, and is discharged from the water outlet faucet 10 through the post-filter element 8.

[0029] In this embodiment, a driving motor 15 is used to simultaneously drive the booster pump 3 and the water pump 6 to achieve the dual functions of filter element pressurization and water extraction from the water storage tank 5, thereby meeting the large flow water output effect of using a small flux membrane, with low cost, simple water circuit and small size.

[0030] Furthermore, as a preferred embodiment, the drive motor 15 is a dual-output shaft motor, and one output shaft of the dual-output shaft motor is transmission-connected to the booster pump 3 , and the other output shaft is transmission-connected to the water pump 6 .

[0031] Furthermore, as a preferred embodiment, the two output shafts of the driving motor 15 are respectively located on two sides of the driving motor 15 .

[0032] Furthermore, as a preferred embodiment, in order to avoid the water outlet of the water pump 6 being blocked and the water in the pump chamber being repeatedly circulated to generate heat, a branch 12 is connected between the pipeline between the filter element 4 and the water storage tank 5 and the pipeline between the booster pump 3 and the post-filter element 8. A pressure-bearing one-way valve 11 is also provided on the branch 12. By presetting the conduction pressure of the pressure-bearing one-way valve 11, the pressure-bearing one-way valve 11 is not conducted when the faucet is opened to discharge water, and the pressure-bearing one-way valve 11 is conducted when the faucet is closed, so that the water pumped out by the water pump 6 is circulated back to the water storage tank 5 through the branch 12.

[0033] Furthermore, as a preferred embodiment, the filter element 4 is also connected to a concentrated water solenoid valve 13, and the concentrated water produced after filtering is discharged by the concentrated water solenoid valve.

[0034] Furthermore, as a preferred embodiment, a one-way valve 7 is connected to the pipeline between the water pump 6 and the post-filter element 8.

[0035] Furthermore, as a preferred embodiment, a pressure switch 9 is also connected to the pipeline between the post-filter element 8 and the water outlet faucet 10.

When the water level in the water storage tank 5 is at a high water level, the water level controller 14 sends a signal to stop the operation of the driving motor 15 and disconnect the water inlet solenoid valve 1 at the same time.

[0037] Specifically, the pressure-bearing one-way valve and the pressure-bearing solenoid valve are both existing conventional accessories, and this article will not elaborate on their specific structures and principles in detail.

[0038] The specific working process in this embodiment is as follows: The water outlet faucet 10 is opened, the pressure switch 9 operates due to pressure release, the driving motor 15 is started, and the booster pump 3 and the water extraction pump 6 are driven to work.

The water extraction pump 6 extracts the purified water in the water storage tank 5 and discharges it from the water outlet faucet 10 through the check valve 7, the post-filter element 8, and the pressure switch 9. At this time, the pressure-bearing check valve 11 is not conducting;

[0039] When the water outlet faucet 10 is closed, when the faucet is closed, the pressure-bearing check valve 11 conducts, so that the water extracted by the water extraction pump 6 circulates back to the water storage tank 5 through the branch 12.

[0040] The above are only the preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model.
