It can be understood that in this embodiment, the connecting piece 11 includes a connecting column and a plurality of elastic clamping ribs protruding from the surrounding wall of the connecting column. Corresponding to the connecting hole 21. When the water circuit board 10 is connected with the filter cartridge seat 20, the connecting hole 21 of the filter cartridge seat 20 is aligned with the connecting column of the connector 11 on the water circuit board 10, and the filter cartridge seat 20 is pressed against the water circuit board 10 by an external force, so that the water circuit board 10 is equipped with The connecting column with a plurality of elastic clamping ribs passes through the connecting hole 21 correspondingly. At this time, the elastic clamping ribs on the peripheral wall of the connecting column are opposed to the hole wall of the connecting hole 21, and the connecting piece 11 and the connecting hole 21 complete the insertion fit. , to complete the connection between the filter element seat 20 and the water circuit board 10, so as to facilitate installation; when a certain filter element seat 20 is to be disassembled from the water circuit plate 10, an opposite external force is applied to remove the connecting hole 21 of the filter element seat 20 from the connecting column Pull out the elastic clamping ribs on the surrounding wall to complete the disassembly of the filter element seat 20. Compared with the first connection method between the water channel plate 10 and the filter element seat 20, the second connection method saves fasteners (such as screws or stud) locking operation, which is convenient for the staff to check or replace the filter element seat 20, reduces the difficulty of disassembly, is simple and convenient to install and disassemble, improves the replacement efficiency, and saves material costs and maintenance costs.

Further, in order to smoothly insert the connecting piece 11 into the connecting hole 21, in this embodiment, each elastic clamping rib on the connecting piece 11 extends in the axial direction of the connecting column, and each elastic clamping rib is far away from the waterway plate. One end of 10 is formed with a guide slope. The elastic clamping rib on the connecting post forms a guide inclined surface corresponding to one end of the connecting hole 21, so that the alignment is convenient when the connecting post is first inserted into the connecting hole 21, and the insertion process is smooth without special effort; at the same time, the connecting hole of the filter element holder 20 21. It is also more convenient and labor-saving when pulling out from the elastic clamping tendons on the peripheral wall of the connecting column.

In the third connection mode between the waterway plate 10 and the filter element seat 20, one of the waterway plate 10 and the filter element seat 20 can be provided with a plurality of connecting buckles, and the other of the two is provided with a plurality of buckle grooves, each A filter element seat 20 is detachably connected to the water channel plate 10 through the engagement of the connecting buckle and the buckle groove. As the third preferred embodiment of the present utility model, the difference between this embodiment and the first two embodiments is that in this embodiment, the waterway plate 10 is provided with multiple connecting buckles (not shown), and the filter element seat 20 is provided with There are a plurality of buckle grooves (not shown), and a plurality of connection buckles corresponding to each filter element seat 20 of the water channel plate 10 are arranged around the periphery of the water inlet 12 and the water outlet 13. The effect of this setting is the same as that of the first two embodiments. So no more details. Specifically, in this embodiment, each connecting buckle is fixedly connected to the water channel plate 10 , and each filter element seat 20 is detachably connected to the water channel plate 10 through the engagement of the connecting buckle and the buckle groove. It can be understood that a plurality of buckle grooves can be arranged on the end of the filter element seat 20 against the water channel plate 10, or can be arranged on the bottom surface of the filter element seat 20 not in contact with the water channel plate 10, and the plurality of button grooves are arranged on the filter element seat 20 Correspondingly, the length and position of the connecting buckle on the waterway plate 10 are adjusted accordingly according to the actual situation. The connection action mode of the connecting buckle and the buckle groove can refer to the second connection method of the filter element seat 20 and the waterway plate 10. The difference in the connection method is that in the third connection method, the connection buckle is deformed when it is squeezed into the buckle groove by an external force, and when the connection buckle fully enters the buckle groove, the connection buckle returns to its original state and is fastened to the buckle groove , it can be understood that the buckle groove should be designed as a structure with a small entrance opening and a large internal space. In this way, it is more convenient to realize the engagement of the connecting buckle and the buckle groove in the way of inserting.

Further, in order to facilitate dismounting, a through hole can also be set on the bottom wall of the buckle groove, so that the connecting buckle can partially protrude from the filter cartridge seat 20 through the through hole. The part protruding from the through hole causes the connecting buckle to shrink inwardly, so that the connecting buckle can exit through the entrance with a smaller opening of the buckle groove.

In this embodiment, the detachable connection between the filter element seat 20 and the water channel plate 10 is realized by the engagement of the connecting buckle and the buckle groove. Specifically, when the water circuit board 10 is connected with the filter element seat 20, the buckle groove of the filter element seat 20 is aligned with the connection button of the water circuit board 10, and the filter element seat 20 is pressed against the water circuit board 10 by external force, so that the connection buttons of the water circuit board 10 correspond to each other. Engage with the buckle groove of the filter element seat 20, and the connection between the filter element seat 20 and the water circuit board 10 is completed at this time; Apply an opposite external force again, pull out the buckle groove of the filter element seat 20 from the connection buckle of the water channel plate 10, and the disassembly of the filter element seat 20 can be completed, which is convenient for the staff to check or replace it, reducing the difficulty of disassembly. The installation and disassembly are simple and convenient, the replacement efficiency is improved, and the material cost and maintenance cost are saved.
