Connecting structure, filter core assembly and water purifying device

Abstract

The invention relates to a connecting structure. The connecting structure comprises a support unit and a switchover unit which is rotationally connected with the support unit, wherein the rotating axis of the switchover unit is defined as a main axis; the switchover unit comprises multiple clamping and connecting pieces; installing gaps are formed among the multiple clamping and connecting pieces; the multiple clamping and connecting pieces can move mutually to reduce the area of the installing gaps and play a locking role; the multiple clamping and connecting pieces can also move mutually to expand the area of the installing gaps and play an unlocking role. The invention also relates to a filter core assembly comprising the connecting structure and a water purifying device comprising the filter core assembly. The connecting structure disclosed by the invention has the advantages that the operation is simple, and a mechanical connection function can be quickly realized. The filter core assembly comprising the connecting structure, disclosed by the invention, is simple and convenient in disassembly and assembly, is labor-saving in operation and is beneficial for increasing the installing efficiency and improving the user experience. The water purifying device disclosed by the invention is stronger in purification ability and flexible and convenient to use.

Problems solved by technology

In the process of plugging and fitting the filter element with the adapter, the installer needs to overcome the friction of the sealing ring at the adapter, and when rotating the filter element, it is also necessary to overcome the friction between the sealing ring and the side ribs of the filter element and the adapter during the entire rotation process. Therefore, the process is very laborious, and it is easy to cause the problem of water leakage or damage to the connection structure due to improper installation of the filter element due to uneven force applied by the installer.

In addition, when some filter elements are replaced, it is necessary to press buttons to unlock the button position of the filter element. The operation of changing the element is cumbersome and complicated, labor-intensive and time-consuming, and the assembly efficiency is low.
