Preferably, described locking device is a locking plate, and described locking plate upper and lower is respectively equipped with a card base I, and described tube connector upper and lower has hole clipping I, and described card base I wore hole clipping I and catching groove; Comparatively simple and practical locking device.
Preferably, described locking plate middle part is provided with two card base II, and described tube connector middle part is provided with hole clipping II, have the trepanning II coaxial on the described tube connector with trepanning I, described hole clipping II passes trepanning II, and the end of described card base II is provided with projection, and described projection passes on the inwall that hole clipping II is stuck in trepanning II; Further increase the coupling mechanism force of locking plate.
Preferably, the end of described card base I is provided with boss, and described boss passes the other end that hole clipping I is stuck in hole clipping I; Prevent that locking plate from moving forward and backward.
Preferably, described boss is semicircle; Install and remove than being easier to.
Preferably, be provided with stop system between described filter cartridge seat, filter core supporting seat and the filter core; Filter core on the filter and filter cartridge seat and filter core supporting seat are closely cooperated.
Preferably, described stop system comprises the lug that is located on the filter core, be located at support level corresponding with lug on the filter core supporting seat, be located at locking groove on the filter core, be located between filter core supporting seat and the filter cartridge seat and the corresponding arresting lever of locking groove, is provided with retaining spring between described filter cartridge seat and the arresting lever.
Preferably, be provided with sealing ring between described water inlet pipe and the trepanning I; Be provided with sealing ring between described outlet pipe and the trepanning I; Prevent that the tube connector place from leaking.
Compared with prior art, the utility model has the advantages that: use locking device, water inlet pipe and outlet pipe are connected more firm with tube connector, be not easy, leak, the normal operation of assurance filter core.
