Abstract

A shower installation providing filtered water includes a faucet (1), a filter device (2), and a diverter valve (3). The output of the faucet is connected to the input of the filter device, and the output of the filter device is in turn connected to the input of the diverter valve. One of the outputs of the diverter valve is connected to a shower handle through a water hose whereas the other output of the diverter valve is connected to a fixed overhead shower head through another water hose. In operation, hot water and cold water are mixed in the faucet and is supplied to a shower handle and to the shower head whereby in both cases water is filtered by the filter device. Thus, one filter device can be used for both the shower handle and the shower head.

As shown in Figs. 1 and 5-8, the shower water ejection system having a filter device includes: a faucet 1, a filter device 2, and a 3-way valve 3. Wherein, the output of the faucet 1 is connected to the input of the filter device 2, and the output of the filter device 2 is connected to the input of the 3-way valve 3. Moreover, one of the outputs of the 3-way valve 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.
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.
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.
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.
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.
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.
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.
