The connection locking process of the sealing joint in the present application is explained below:

firstly, the male connector 10 is inserted into the female connector 20, then the filter cartridge 100 is rotated, and the fixture blocks 42 are in contact with the groove bottom surface 4111 of the clamping grooves 411; continuing to rotate the filter cartridge 100, the fixture block 42 slides into the clamping groove 411 gradually under the guiding action of the guiding surface 4114; when the filter cartridge 100 is rotated, the locking block 42 gradually falls off the guide surface 4114 and contacts the inverted surface 4115.

With reference to fig. 1 to 7, a complete embodiment of the present application is described below:

the utility model provides a waterway plate structure integrally formed by a mould, which does not need complex operations such as hot plate welding and the like, and the structure can be divided into two parts according to different assembly positions, namely a waterway plate assembly part (comprising a waterway plate, a female joint 20 and a clamping seat 41) and a filter element assembly part (comprising a filter element 100, a male joint 10 and a clamping block 42).

1. Installation and locking process of the filter cartridge 100:

a user firstly pushes the filter element 100 to the bottom, after the filter element 100 is pushed to the bottom, the user rotates the filter element 100, when the filter element 100 rotates to a certain angle, the fixture block 42 on the male connector 10 of the filter element 100 contacts with the guide surface (the guide surface 4114) of the clamping seat 41, at the moment, when the user rotates the filter element, the filter element 100 decomposes the resistance of the sealing ring (the sealing element 30) into the resistance along the inclined surface and the resistance vertical to the inclined surface (the inclined surface here refers to the guide surface 4114) through the clamping seat 41, and therefore the purpose of labor-saving installation of the filter element 100 is achieved.

Note that, as shown in fig. 8, F is the resistance of the filter element 100 to the seal ring when the filter element 100 is installed; f is a reaction force generated by the fixture block 42 pressing the cartridge 100 against the guide surface 4114 when the cartridge 100 is installed, where f1 is a vertical component of f, and f2 is a horizontal component of f. f3 is an external force required for installing the filter cartridge 100, and the filter cartridge 100 can be installed when the external force is larger than the reaction force.

It is apparent that the force with which the user installs the cartridge 100 is closely related to the angle of the ramp (angle γ) of the cartridge 41 during this process. According to the application, the angle (included angle gamma) of the lead-in surface is designed to be less than or equal to 30 degrees according to various aspects such as the friction force of an injection molding piece and the resistance of a sealing ring, so that a user feels comfortable.

When the filter element 100 continues to rotate to a certain angle, the filter element 100 is separated from the lead-in surface;

the user continues to rotate the cartridge 100 until the cartridge 100 abuts the run-out surface 4116 on the cartridge 41, at which point the installation is complete.

2. Disassembly of cartridge 100:

when the filter cartridge 100 is installed, the removal of the filter cartridge 100 needs to overcome the resistance along the reverse-buckling surface 4115 opposite to the removal direction of the filter cartridge 100, and at this time, the reverse-buckling surface 4115 on the clamping seat 41 has a certain effect of preventing the filter cartridge 100 from being removed. Greatly reducing the risk of the filter element 100 falling out after the filter element rotates automatically in long-term operation.

According to the application, the risk that the filter element 100 is mistakenly moved and separated can be obviously reduced when the height difference of the inverted surface 4115 (the height difference between the highest point and the lowest point of the inverted surface 4115 in the height direction of the clamping seat 41) is 0.5mm according to a large amount of experimental data of the use condition of a user and a laboratory for many years.

Meanwhile, the angle of the inclined surface (included angle β) of the inverted surface 4115 should be as small as possible, otherwise the user will experience great resistance when detaching the filter cartridge 100. Of course, removal of the cartridge 100 also requires overcoming the resistance of the seal ring.

Preferably, the angle β is equal to 3 °
