3 is connected to a bathroom shower head through a water hose; while another output
of the 3-way valve 3 is connected to a flower shower head through another water hose.
[0017] As shown in Figs. 2-4, in a first embodiment of the present invention, the filter
device 2 includes: an upper shell 21, a lower shell 22, an upper cover 23, a lower
cover 24, and a filter core 25. Wherein, the upper shell 21 is sleeved around the
outer side of the lower shell 22. The water channel of the upper shell 21 is sleeved
around the outer side of water channel of the upper cover 23. The lower end of the
water channel in the upper shell 21 is provided with a fastening slot 26; while the
lower end of the water channel of the upper cover 23 is provided with a fastener 27
to match and work in cooperation with the fastening slot 26 of the upper shell 21
water channel. A spring 28 is provided between the upper shell 21 and the upper cover
23, to keep the upper shell 23 fastened to the lower cover 24. The filer core 25 is
placed in an inner chamber of the lower cover 24. The upper end outer side of the
lower cover 24 is connected to the upper end inner side of the lower shell 22 through
the respective inner threads and outer threads.
[0018] Moreover, as shown in Figs. 2-4. In a first embodiment of the present invention,
in order to strengthen the tight seal between the water channel of the upper cover
23 and the water channel of the upper shell 21, the water channel outer side of the
upper cover 23 is provided with a tight seal slot, and an O-shape tight seal ring
29 is provided in the tight seal slot, to work in cooperation with the water channel
inner side of the upper shell 21. Further, in order to strengthen the tight seal between
the water channel of the lower cover 24 and the water channel of the lower shell 22,
the water channel outer side of the lower cover 24 is provided with a tight seal slot,
and an O-shape tight seal ring 29 is provided in the tight seal slot, to work in cooperation
with the water channel inner side of the lower shell 22.
[0019] Furthermore, as shown in Figs. 2-4. In a first embodiment of the present invention,
in order for the filter device 2 to connect to the faucet 1 and the 3-way valve 3,
the upper end of the upper shell 21 is provided with outer threads working in cooperation
with the input of the 3-way valve 3, while the lower end of the lower shell 22 is
provided with inner threads working in cooperation with the output of the faucet 1.
[0020] The operation principle of the first embodiment of the present invention is as follows:
hot water and cold water is mixed in the faucet 1, then it is output from the faucet
1 to the filter device 2 placed above the faucet 1 for filtering. Subsequently, the
mixed and filtered water is supplied to the bathroom shower head or a flower shower
head, after passing through a 3-way valve 3. In installing the filter device 2, firstly,
connect the lower shell 22 to the faucet 1, then rotate the upper shell 21 as shown
in Fig. 3, to detach the fastening slot 26 from the fastener 27. At this time, the
upper shell 21 is ejected upward due to the action of the spring 28, then connect
and fix the upper shell 21 to the 3-way valve 3, to complete the installation process.
When the filter core 25 requires replacement after certain period of usage, it can
be replaced as follows: turn loose the upper shell 21 to detach it from the 3-way
valve 3 as shown in Fig. 6. Then, press the upper shell 21 downward as shown in Fig.
7, so that the fastening slot 26 of the upper shell 21 is fastened to the fastener
27 of the upper cover 23. Subsequently, as shown in Fig. 8, turn loose the lower shell
22, to detach it from the faucet 1. At this time, the entire filter device 2 is detached
from the faucet 1, so that the filter device 2 can be taken out to replace the filter
core 25.
[0021] In the second embodiment, as shown in Fig. 9, in order to facilitate assembly and
detaching, the input on the upper portion of the filter device 2 is connected to the
output of the faucet 1 on its lower portion. The 3-way valve 3 is installed above
the faucet 1, so that the output on the lower portion of the filter device 2 is connected
to the input of the 3-way valve 3 through a pliable tube 4. The 3-way valve 3 can
be fixed onto the faucet 1.
[0022] The operation principle of the second embodiment of the present invention is as follows:
hot water is mixed with cold water in the faucet 1, then it is output from the faucet1
and input to the filter device 2 placed below the faucet 1 for filtering. Then, the
mixed and filtered water is supplied to a 3-way valve 3 via a pliable tube 4, to be
supplied to a bathroom shower head or a flower shower head, after passing through
the 3-way valve 3. In installing the filter device 2, firstly, connect the upper end
of the filter device 2 directly to the output of the faucet 1 at its lower portion
by means of threads. Then, connect the filter device 2 and the 3-way valve 3 through
the pliable tube 4. When the filter core 25 requires replacement after certain period
of usage, it can be replaced simply by turning loose and detaching the filter device
2 from the faucet 1 and the pliable tube 4, to replace the filter core 25 readily.
