The existing swimming pool filter element generally includes an inner framework, a filter layer outside the inner framework, a top cover and a bottom cover. Because the filter layer is a soft structure, the whole swimming pool filter element is supported by the inner framework.
Under the long-term impact of water flow, the support strength of the inner framework is required to be high, and the hardness and durability of the inner framework are required to be high. Even if it is used for a long time, it is not easy to deform.
The existing production process of the inner skeleton is to produce a whole mesh sheet, then cut it, and then bend the mesh sheet to form a cylindrical structure;
Finally, the head and tail joints are bonded by glue, which has many processes and low production efficiency. Moreover, such inner framework has low support strength, low hardness, and is not strong enough to be durable. It is easy to deform after long-term water impact;
In addition, the top cover of the existing swimming pool filter element is generally flat structure, and the structural design is relatively simple and fixed. When it needs to be installed into the filter, it also needs additional connecting parts for assembly, so the installation is not convenient.
Therefore, swimming pool filter element can be selected according to the actual demand, easy installation of the swimming pool filter element is an urgent technical problem to be solved in the industry
