Technical Field

[0001] The utility model relates to the technical field of swimming pool equipment, in particular to a swimming pool activated carbon filter element quick replacement device. Background Art

[0002] Swimming pools are places where people often use, relax and have fun. According to their uses, they can be divided into competition swimming pools, training swimming pools, diving swimming pools and children's swimming pools. The design of swimming pools should comply with relevant national regulations and include a complete circulating water purification process to meet my country's water quality and hygiene standards.

[0003] The swimming pool water filtration device is necessary equipment to ensure the water quality of the swimming pool. Activated carbon filter elements are commonly used in the filtration device. Activated carbon has a good adsorption and purification effect. Since some swimming pools do not have independent purification rooms, their filtration equipment is set on one side of the swimming pool. Under the impact of swimming pool water or the vibration of the filter pump, the filter element connected by threads has the risk of loosening or cracking at the connection position, and the filter element connected by threads is inconvenient to replace. Therefore, it is necessary to provide a stable and quick-replacement filter element connection method while ensuring the sealing performance. Utility Model Content

[0026] Specifically, the filter assembly 3 includes an outer shell 31, a filter element 32, an end cover 33, a plug 34, a sealing ring 35 and a clamping shaft 36. The filter element 32 is clamped in the outer shell 31, the end cover 33 is connected to the outer side of the top of the outer shell 31 by a thread, the plug 34 is fixedly arranged on the top of the end cover 33, the sealing ring 35 is sleeved on the outside of the plug 34, the clamping shaft 36 is fixed to the outside of the plug 34, the bottom of the folding frame 43 is located on the outer side of the bottom of the outer shell 31, the top of the knob 44 contacts the bottom of the outer shell 31, the plug 34 is clamped in the water outlet pipe 2, a clamping groove matching the clamping shaft 36 is opened on the surface of the water outlet pipe 2, a supporting protrusion is arranged at the bottom of one end of the clamping groove on the surface of the water outlet pipe 2, a clamping groove matching the sealing ring 35 is opened on the surface of the plug 34, the outer wall of the sealing ring 35 is in close contact with the inner wall of the water outlet pipe 2, and a sealing gasket is arranged between the inside of the water outlet pipe 2 and the top of the plug 34.

[0027] In this embodiment, when working, the pump runs, so that the pressurized water flows from the outlet pipe 2 at the bottom of the water pump base plate 1 into the end cover 33, and enters the middle of the filter element 32 from the inner guide pipe of the end cover 33, and is adsorbed and filtered by the activated carbon in the filter element 32 and seeps out from its surface to achieve a filtering effect.
