Amount of water flow (Q) = sectional area (A) multiplied by flow velocity (V)

  This allows the showerhead user to provide real-time statistical information on the total amount of filtered water that has passed through the handle filter 60 by the simple means of viewing the LCD display circuit 302 through the transparent lid 201 of the warning pod 200. Data can be obtained. Once the total amount of filtered water that has passed through the handle filter 60 reaches (or is likely to reach) a predetermined critical value of the rated useful life of the particular handle filter 60, the microprocessor 301 A warning signal having current data on the total amount of water is sent to the LCD display circuit 302 to prompt the user to notice that it is time to replace the handle filter 60 accordingly. Quality is guaranteed, thereby guaranteeing water quality after filtration. Therefore, the user can avoid the adverse health effects caused by impure water, which are caused by missing the replacement time and continuing to use the handle filter 60 that has become ineffective.

  See further FIGS. 23-28 for replacement or charging of the handle filter 60. The first preferred exemplary embodiment for a handheld showerhead with a device to warn in advance of filter replacement of the present invention further comprises a battery charging base 400, which is a set of active charging electrodes.

In this case, the shape of the battery charging cavity 401 is devised to resemble the shape of the installation cavity 202 in the warning pod 200, but the installation cavity 202 can be appropriately accommodated therein by making it slightly larger than this. Then, a charging operation suitable for the rechargeable battery in the warning pod is performed (as shown in FIGS. 27 and 28).

  The power of the rechargeable battery 303 in the warning pod 200 may be lost if the handle filter 60 is replaced several times. In the replacement or charging operation mode of the handle filter 60, first the edge close to the edge of the transparent lid 201 in the warning pod 200 is placed along the groove 116 guiding the finger on the opposite side 102 of the shower head shell 100. And then an upward force F2 is applied to the installation cavity 202 (as shown in FIG. 24), causing the snap-on latch engagement notch 204 of the warning pod 200 to bounce back. , Disengaged from the snap-type latch engaging projection 115 in the recessed socket 113 of the showerhead outer shell 100 (as shown in the enlarged view on the upper right side of FIG. 24), and then the upward force F2 is continuously applied to the installation cavity 202. In addition, the entire warning pod 200 is completely removed from the indentation socket 113 on the opposite side 102 of the showerhead shell 100. Finally, as shown in FIGS. 25 and 26, the removable warning pod 200 is inserted into the battery charging cavity 401 of the battery charging base 400, and the rechargeable battery 303 in the warning pod 200 is appropriately charged (see FIG. 25 and FIG. 26). As shown in FIGS. 27 and 28).

  Accordingly, the warning pod 200 can be inserted into the indentation socket 113 on the opposite side 102 of the shower head shell 100 for normal measurement and warning functions, and can be removed from the indentation socket 113 for battery charging operations. As a result, not only can the power be appropriately applied to the shower head outer shell 100, but also the charging operation can be performed by separating the warning pod 200 from the shower head outer shell 100. As a result, the conventional “ The problem that arises in the “handheld showerhead with device to warn in advance of filter replacement” is completely solved, even if there is no DC power supply in the signal circuit device 300, the entire showerhead shell 100 is discarded and No need to replace. This not only eliminates waste of resources, but also saves the economic costs incurred by frequently changing the showerhead. As a result, this is an advantage for market sales by increasing the desire to continue to use the “handheld showerhead with a device that warns in advance of filter replacement” of the present invention.
