2. Description of the Related Art Residual chlorine in tap water may irritate the skin or damage hair when bathing or washing hair. Therefore, it is desirable to remove residual chlorine from tap water used for bathing and washing hair in bathrooms and showers. A clean water shower device for removing residual chlorine installed in a room or the like is provided.

FIG. 1 shows an example of a conventional water purification shower device using a water purification cartridge. This water purification shower device has a slide bar 1 having a water purification function, a switching valve 2, a faucet 3, a raw water hose 4, a shower hose. 5, a shower head 6 and a slide hook 7. Hot water supplied from the faucet 3 reaches the switching valve 2 through the raw water hose 4. By operating the switching valve 2, purified water or raw water is sprinkled from the shower head 6. The shower of purified water is used for bathing and washing hair, and the shower of raw water is used for washing bathtubs and bathrooms.

FIG. 2 is a vertical cross-sectional view of an example of a slide bar 1 in a conventional water purification shower device. A water purification cartridge 8 is built in the slide bar 1 (a slide bar with a water purification cartridge is also called a water purification shower bar). A water passage 9 is formed in the central portion of the water purification cartridge 8. The raw water coming from the raw water hose 4 is shown in Fig. 2.
