[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] Example:

[0036] See Figure 1 and Figure 2This embodiment discloses a water purification device for domestic water, including a water tank 10, a ceramic membrane module 20, a control component 30, an inlet pipe 40, and a drain pipe 50. The water tank 10 stores raw water (water to be purified) and purified water; the ceramic membrane module 20 purifies the raw water; the control component 30 controls the water flow within the water tank 10; the inlet pipe 40 supplies raw water to the water tank 10; and the drain pipe 50 discharges purified water.

[0037] Specifically, the water tank 10 has three zones: a raw water zone 11, a clean water zone 12, and a control zone 13. The ceramic membrane module 20 is located in the raw water zone 11, and the inlet pipe 40 is mounted on the water tank 10, with its outlet located in the raw water zone 11. The control module 30 is located in the control zone 13, and a water collection pipe 21 connects the control module 30 to the ceramic membrane module 20. The outlet of the control module 30 is located in the clean water zone 12. Additionally, a level sensor 60 is located at the top and bottom of both the raw water zone 11 and the clean water zone 12.

[0038] The control assembly 30 includes a water pump and a controller. The water pump's inlet is connected to the end of the water collection pipe 21, and the water pump's outlet is located in the clear water zone 12. Four level sensors 60 are also electrically connected to the controller.

[0039] Drain pipe 50 is installed in clean water zone 12 to provide clean water to users. A water inlet valve is installed on water inlet pipe 40 and a drain valve is installed on drain pipe 50. The water inlet valve and the drain valve are also electrically connected to the controller.

[0040] During operation, the raw water to be purified is delivered to the water tank 10 through the inlet pipe 40, and driven by the water pump to pass through the ceramic membrane module 20. The raw water is purified on the ceramic membrane module 20 and produces clean water. The clean water flows into the water pump from the water collection pipe 21 and then into the clean water zone 12, where it is temporarily stored for use by the user.

[0041] The controller can dynamically adjust the liquid levels in the raw water zone 11 and the clean water zone 12 in real time through four liquid level sensors 60 in the raw water zone 11 and the clean water zone 12, so as to avoid the liquid level in the raw water zone 11 or the clean water zone 12 being too low, which would cause obstacles to the user.

[0042] In this embodiment, the raw water is purified by setting a ceramic membrane assembly 20 in a relatively small water tank 10, and the raw water is made to flow from the raw water zone 11 to the clean water zone 12 by using a control assembly 30. When the user needs water, the clean water zone 12 is provided. This water purification device is small in size, can supply water to a single user, and has the advantages of simple structure and process and low cost.

[0043] In one specific embodiment:

[0044] The ceramic membrane module 20 also includes a support frame 22 and several flat ceramic membranes 23. The support frame 22 is located in the raw water zone 11 and is used to support all the flat ceramic membranes 23. Both ends of each flat ceramic membrane 23 are connected to the water collection pipe 21.

[0045] Specifically, multiple flat ceramic membranes 23 are arranged in parallel with their ends flush, forming a membrane group, and multiple membrane groups are arranged on the support frame 22.

[0046] In addition, the two ends of the flat ceramic membrane 23 in each membrane group are respectively connected to a water collection pipe 24, and a U-shaped branch pipe 25 is provided on the periphery of each membrane group. All the water collection pipes 24 on both sides of the same membrane group are connected to the U-shaped branch pipe 25, and the branch pipe 25 is connected to the water collection pipe 21.

[0047] In this embodiment, the raw water in the raw water zone 11 is drawn through each flat ceramic membrane 23 by the pump. The raw water is filtered by the flat ceramic membrane 23 to remove particulate impurities, sludge, rust, suspended matter, etc., so that the water entering the water collection pipe 24, branch pipe 25 and water collection pipe 21 is clean water. The filtered substances remain in the raw water zone 11.

[0048] Preferably, the bottom of the support frame 22 is a hollow structure, which allows raw water to seep into the entire periphery of the ceramic membrane assembly 20.

[0049] In another specific embodiment:

[0050] The liquid level sensor 60 at the bottom of the raw water zone 11 is positioned higher than the top of the ceramic membrane module 20, thereby ensuring that the ceramic membrane module 20 is submerged in the raw water.

[0051] In another specific embodiment:

[0052] The water pump's outlet is connected to the bottom of the clear water zone 12, the inlet pipe 40 is located at the top of the raw water zone 11, and the drain pipe 50 is located at the bottom of the clear water zone 12. This design ensures that the water in the raw water zone 11 and the clear water zone 12 is in a flowing state, without any dead corners where sediment accumulates.

[0053] In another specific embodiment:

[0054] The liquid level in the raw water zone 11 is located between two liquid level sensors 60 inside it. The liquid level in the raw water zone 11 is controlled by a controller to ensure sufficient water supply.

[0055] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
