[0002] As people's living standards improve, their requirements for the quality of domestic water are also increasing. In daily life, the water flowing from the tap often contains pollutants such as ash and impurities. If these pollutants directly enter household appliances (such as washing machines), they will not only affect the normal service life of the equipment, but also cause secondary pollution of clothes, affecting the washing effect. Therefore, it is particularly important to add a filtration device to the water pipe connection system.

[0003] Currently, there are various water pipe connection devices with filtration functions available on the market. For example, Chinese Patent Publication No. CN212028904U discloses a bathroom connection pipe, which includes a pipe body and a filter section.

[0029] The working principle of the water pipe connector with a filter device in this embodiment is as follows:

[0030] Water flows in through the inlet channel of the second connector, and after being filtered by the second and first filters of the filter section, it flows out through the outlet hole of the first connector. During this process, impurities in the water are trapped by the first and second filters, resulting in clean water. When the filter section needs cleaning or replacement, the first and second connectors can be rotated to separate them, allowing the filter section to be removed for cleaning or replacement.

[0031] The water pipe connector with a filter device in this embodiment has the following advantages:

[0032] 1. The structure is simple and the installation is convenient. It only requires threading the first connecting body and the second connecting body together.

[0033] 2. Excellent filtration effect: Through the dual filtration of the first and second filtration sections, impurities in the water can be effectively removed;

[0034] 3. Easy maintenance: When the filter needs to be cleaned or replaced, simply rotate the first connector and the second connector to separate them and remove the filter.

[0035] 4. The first connector is made of transparent PP material, which allows for direct observation of the working status and dirt level of the filter section, facilitating timely replacement or cleaning of the filter section;

[0036] 5. The support components are evenly distributed around the water outlet, which can effectively support the filter section and prevent the filter section from deforming or shifting.

[0037] 6. The first connector, the filter section, and the second connector share the same center line, which ensures smooth water flow and reduces water flow resistance.

[0038] The water pipe connector with filter device of this embodiment is suitable for various occasions where water impurities need to be filtered, such as domestic water and industrial water. Especially in areas with poor water quality, using the water pipe connector with filter device of this embodiment can effectively improve water quality, protect water-using equipment, and extend the service life of the equipment.
