Description

Handheld shower head with update filter warning function

【Technical field】

The present invention provides a hand-held shower head with update filter early warning function, especially a kind of water flow through the filter in the handle of the hand-held shower head. In order to remind the user to update the filter of the hand-held shower head in time to ensure its water filtration quality. the

【Prior Technology】

As a result of modern industrialization and lack of attention to environmental protection, rivers are polluted by industrial wastewater, household wastewater, garbage and livestock excrement, etc., and domestic water is full of pesticides, chemicals and various impurities. The factory uses chlorine to purify the water, but there are also residual chlorides in the water that affect human health. As a result, people purchase water filtration equipment to filter drinking water, and add filters to shower water in order to obtain a better quality. The principle of bathing water quality is to use internal activated carbon, sulfurous metal, KDF and other adsorptive filter materials to absorb or remove various pesticides, chemical substances and impurities in the water. the

Currently known hand-held shower heads with filters, such as U.S. Patent No. 410107046, No. 6016977 and No. 6270023, etc., can achieve the effect of filtering shower water, but the handle of the hand-held shower head After the filter in the filter is used for a period of time, there is a saturation point (or service life), which is calculated based on the maximum filtered water volume, for example, the maximum filtered water volume is 1500 gallons as the filtered water saturation point Once the filter reaches the saturation point, the filtering effect will be lost due to the accumulation of filtered impurities, and it must be updated immediately to maintain its filtering effect. the

However, although the manufacturers of the filters currently available in the market have listed the number of gallons of their useful life (Service Life) on the appearance of the filter, they do not provide any instrument for measuring the value of the gallon. or tool, so when the user purchases a new filter, the manufacturer changes it to inform that the update should be done after half a year or several months, but if the consumer updates in advance to avoid the saturation point of ultra-filtered water When the time is too long, it will form another form of waste and increase the economic burden; but if it is renewed after the time beyond the saturation point of the filtered water, it will lose its originality because the filter is full of filtered dirt. It has the effect of filtering water, and the filtered water flowing out is farther and cleaner than the water without a filter, and at the same time, the health damage caused by invading the capillary pores of the human skin will be more serious. the

However, the time for the hand-held shower head filter to reach its saturation point also varies with the number of users in each family. In one family, the effective service period of the hand-held shower head filter is 250 days; while in a family of six people, the effective use period of the hand-held shower head filter is only 125 days. the

In other words, when the above-mentioned prior patents reach their filter water saturation point, there is no early warning function, and the inability to achieve correct metering control or any recording, so that the time of timely update will always be missed, and the time of update is still unknown. Continuing to use the filter that has lost its filtering effect will cause discomfort such as skin allergies or itching after use. Moreover, the filter cannot effectively filter out the chlorine in the water, so that it will accumulate on the skin for a long time, which will cause cancer risk. It proves that the practicability effect of the above-mentioned prior patents is not obvious, and not ideal. the
