For the arrangement of the guide grooves 11 and the guide inclined surfaces 12 in the mating structure, there may be one guide inclined surface 12 behind one guide groove 11 in the clockwise or counterclockwise direction of the circumferential direction of the valve head 1, one guide inclined surface 12 behind one guide inclined surface 11, and the arrangement direction of 2 guide grooves 11 and 2 guide inclined surfaces 12 is identical, that is, the 2 guide grooves 11 are arranged in a central symmetry manner with the center of the valve head 1 as the center, and the 2 guide inclined surfaces 12 are arranged in a central symmetry manner with the center of the valve head 1 as the center.
Corresponding to the installation of 2 guide slots 11 and 2 guide inclined planes 12, the number of the filter element clamping ribs 21 is 2, the 2 filter element clamping ribs 21 are distributed in a central symmetry mode by taking the center of the filter element tank body 2 as the center, and the setting extension direction of the 2 filter element clamping ribs 21 is consistent with the setting extension direction of the guide slots 11 and the guide inclined planes 12.
The examples of the guide groove 11, the guide inclined surface 12, and the cartridge engaging rib 21 are given here only for explaining the principle of implementation of this embodiment, and are not limited to this embodiment.

Specifically, as shown in fig. 2 to 5, the tail end of the first assembling plane 112 is connected with a first inclined plane 111 which is inclined downward, as shown in fig. 12, when the filter element clamping rib 21 is assembled into the guide groove 11, the fourth inclined plane 213 is matched with the first inclined plane 111, and the filter element clamping rib 21 starts to move upwards along the inclined direction of the first inclined plane 111 through the matching of the two inclined planes, so that the matching of the first inclined plane 111 and the fourth inclined plane 213 plays a role in guiding, and the filter element clamping rib 21 is beneficial to quickly upwards; meanwhile, the inclined plane height of the first inclined plane 111 can control the ascending speed of the filter element tank body 2, so that the assembly of the filter element tank body 2 is promoted, and the filter element clamping ribs 21 can ascend to the expected height in a smaller rotation angle range. On the contrary, as shown in fig. 12, when the filter element clamping rib 21 is rotated out of the guide groove 11, the cooperation between the filter element clamping rib 21 and the guide groove 11 is directly changed from the cooperation between the second assembling plane 212 and the first assembling plane 112 to the cooperation between the fourth inclined plane 213 and the first inclined plane 111, in the process, the fourth inclined plane 213 directly falls to be matched with the first inclined plane 111, so that a larger descending space of the filter element tank 2 is provided, the filter element clamping rib 21 is conveniently and smoothly contacted with the guide inclined plane 12, and an advantage is provided for the filter element tank 2 to automatically withdraw from the valve head 1.
Specifically, as shown in fig. 9 and 10, the tail end of the filter element clamping rib 21 is provided with a third inclined surface 211 which is inclined downwards, as shown in fig. 11, when the filter element clamping rib 21 is unscrewed, the filter element clamping rib 21 is moved out of the guide groove 11, then the third inclined surface 211 moves to abut against the guide inclined surface 12, and by utilizing the inclined downwards characteristic of the guide inclined surface 12, the filter element clamping rib 21 is forced to descend until the filter element clamping rib exits the valve head 1 when the filter element tank 2 is continuously rotated.
Further, as shown in fig. 6 to 8, an inner boss 14 protruding inwards is arranged on the inner side surface of the valve head 1, and the radius of a circular ring where the boss surface of the inner boss 14 is located is smaller than that of a circular ring where the inner ring surface 13 of the valve head 2 is located; an inner boss 14 is provided with a guide groove 11 and a guide inclined surface 12, the guide inclined surface 12 is positioned at one end of the inner boss 14, and the tail end of the guide groove 11 is connected with the other end of the inner boss 14 and directly transits to the inner annular surface 13. Therefore, the rear end of the guide groove 11 is connected with the inner annular surface 13, so that the filter element clamping rib 21 is clamped into the guide groove 11 at the section of the guide groove 11 to be matched with the guide groove, and when the guide groove 11 is removed, the outer side surface of the filter element clamping rib 21 is matched with the inner annular surface 13, so that the filter element clamping rib and the inner annular surface are not interfered with each other to form a segmented type of well-defined matching.
The working principle of the cartridge mounting structure of the present invention, that is, the cartridge mounting method for the cartridge mounting structure of the present application, will be further described with reference to fig. 13 to 17, including the steps of:
1) The top of the filter element tank body 2 is arranged in the valve head 1 from the bottom of the valve head 1 upwards;
2) The filter element tank body 2 is rotated, so that the filter element clamping ribs 21 are clamped in the guide grooves 11.
More specifically, the operation steps are as follows:
when the filter element tank body 2 is assembled, the filter element tank body 2 is inserted into the valve head 1, and the filter element tank body is slightly rotated until the third inclined surface 211 of the filter element clamping rib 21 abuts against the guide inclined surface 12, as shown in fig. 13;
continuing to rotate the filter element tank body 2, so that the filter element clamping rib 21 rotates towards the guide groove 11 in the inner ring surface 13 between the guide inclined surface 12 and the adjacent guide groove 11 until the fourth inclined surface 213 of the filter element clamping rib 21 contacts the first inclined surface 111 of the guide groove 11, as shown in fig. 14, so that the engagement of the filter element clamping rib 21 and the guide groove 11 starts from the engagement of the fourth inclined surface 213 and the first inclined surface 111, and at the moment, continuing to rotate the filter element tank body 2, so that the fourth inclined surface 213 climbs upwards along the first inclined surface 111;
continuing to rotate the filter element tank body 2 so that the fourth inclined surface 213 climbs onto the first assembling plane 112, at this time, the matching of the filter element clamping rib 21 and the guide groove 11 is changed into the matching of the second assembling plane 212 and the first assembling plane 112, as shown in fig. 15 and 16;
the cartridge can 2 continues to rotate until the fourth inclined surface 213 contacts the second inclined surface 113, as shown in fig. 17, at which time the cartridge catch 21 reaches the end point, and is restrained by the second inclined surface 113, so that it can no longer rotate in the above-described direction.
When the cartridge housing 2 is unscrewed, the cartridge housing 2 is rotated in the opposite direction at the time of assembly. Initially, as shown in fig. 17, the fourth inclined surface 213 is engaged with the second inclined surface 113;
continuing to rotate the filter element tank body 2, under the cooperation of the second assembling plane 212 and the first assembling plane 112, the filter element clamping rib 21 moves towards the direction of unscrewing the guide groove 11, as shown in fig. 15 and 16;
continuing to rotate the cartridge can 2, so that the fit length between the second assembly plane 212 and the first assembly plane 112 is gradually reduced until the second assembly plane 212 is separated from the first assembly plane 112, at this time, the cartridge can 2 moves downward due to the gravity action of the cartridge can 2, so that the fourth inclined plane 213 starts to be matched with the first inclined plane 111, as shown in fig. 14;

It is apparent that when the first assembling plane 112 of the guide groove 11 is provided with the protrusion 31, the second assembling plane 212 of the cartridge catch 21 is provided with the groove 32, and the protrusion 31 is adapted to the position of the groove 32; conversely, when the first assembling plane 112 of the guide groove 11 is provided with the groove 32, the second assembling plane 212 of the cartridge clamping rib 21 is provided with the protrusion 31, and the protrusion 31 is adapted to the position of the groove 32. In either way, post-assembly limiting can be achieved. In this manner, the length of the projection 31 and the length of the recess 32 are both less than the length of the first and second mounting planes 112, 212.
As another preferable mode, as shown in fig. 19, the limiting structure includes a groove 32 disposed in the guide groove 11, and when the filter element clamping rib 21 is installed in the guide groove 11, the filter element clamping rib 21 is clamped into the groove 32 to form a limit. In this way, the length of the recess 32 corresponds to the length of the second fitting plane 212.
Through limit structure, can prevent effectively that filter core card muscle 21 of filter core jar body 2 from withdraw from guide way 11 easily, simultaneously, installer obtains the feel of a feedback, improves the user experience of product.
