Embodiment five
As shown in fig. 7, the present embodiment provides a kind of inversion filter core 300, equally there are three water routes.In this embodiment only
One fixed diversion tower 301 is set, and the diversion tower 301 sealing is plugged in filter flask lid 302, and three are provided with filter flask lid 302
Individual runner, diversion tower 301 are fixed on the upper end cover 7 of filter material 6.The first end of diversion tower 301 is provided with two ports of export, diversion tower
301 the second end is coaxially provided with two tubular side walls, and outside cylindrical side wall and the upper end cover 7 of filter material 6 seal
Grafting, internal cylindrical side wall and the central tube 61 of filter material 6 seal grafting.Inner cylinder bodily form side wall and external cylinder
Annular space between shape side wall connects with first exit end 3011, the inner space of inner cylinder bodily form side wall and second outlet
The connection of end 3012.The interface docked with two ports of export of diversion tower 301, first exit end are respectively equipped with filter flask lid 302
3011 sealings are plugged in the first interface 3021, and the sealing of second outlet end 3012 is plugged in the second interface 3022.First
Interface 3021 is connected with first flow l1 by first check-valve 303, it is preferred that first check-valve 303 is arranged on first-class
In road l4, allow the water to enter first flow l4 from first exit end 3011, but be unable to reverse backflow.Similarly, the second interface
3022 are connected with second flow channel l5 by second check-valve 304, allow the water to enter second flow channel l5 from second outlet end 3012, but
It is unable to reverse backflow.Space between the outer wall of diversion tower 301 and the inwall of filter flask lid 302 passes through the 3rd check-valves 305 and the 3rd stream
Road l6 is connected, it is preferred that the 3rd check-valves 305 is arranged in third flow channel l6, allows the water to enter diversion tower from third flow channel l6
In space between 301 outer walls and the inwall of filter flask lid 302, but it is unable to reverse backflow.
The inversion filter core 100 of the embodiment, raw water enter the outer wall of diversion tower 301 and filter flask lid 302 by third flow channel l6
Space between inwall, flow in the space between filter material 6 and filter flask 1, enter filter material 6 and central tube 61 after the filtering of filter material 6
Between gap, then the through hole through the tube wall of central tube 61 enter central tube 61 in formed pure water.In the pressure of the water of outside input
Under effect, pure water flows through second outlet end 3012 from central tube 61 and flowed out through second check-valve 304 from second flow channel l5；Filter material 6
Waste water between central tube 61 flows through first exit end 3011 and flowed out through first check-valve 303 from first flow l4.When the filter
When core is inverted or is horizontal positioned, the residual water for preventing it internal by three check-valves is spilt.
From the above mentioned, inversion filter core 100 of the present utility model is using the first diversion tower 3, the second diversion tower 4 and compression bullet
Spring 5, which forms one, to be inserted into machine in filter core by the switch valve for promoting the second diversion tower 4 to be moved relative to the first diversion tower 3
After in first 200, second diversion tower 4 top is opened by backstop muscle 205, so as to open each runner；When needing to change filter core, will filter
Core is pulled down from head 200, the return of the second diversion tower 4 is now made in the presence of compression spring 5, so as to close each runner, i.e.,
Filter core inversion or its horizontal positioned internal water is set also not to spill.The non-return structure is simple, and cost is low, using corresponding construction
First diversion tower 3 and head 200, the filter material 6 with two water routes or three water routes can be respectively suitable for.
The schematical embodiment of the utility model is the foregoing is only, is not limited to model of the present utility model
Enclose.All combinations of illustrated feature are not necessarily the solution that the utility model is limited in embodiment, can be with
