Abstract

A water filter and alert assembly for bathroom use includes a housing, at least one filter element, an alert device, and a cap. The housing has an externally threaded end, an internally threaded end, and a water passageway. The at least one filter element is disposed in the water passageway. The alert device includes a temperature sensing element and a temperature indicating element, wherein the temperature sensing element is provided in the water passageway to sense water temperature, and the temperature indicating element is configured to show water temperature and alert messages. The cap has an externally threaded end and an internally threaded end. The internally threaded end of the cap is connected with the externally threaded end of the housing so as to guide outgoing water and retain the at least one filter element.

Claims

1. A water filter and alert assembly for bathroom use, comprising:

a housing having an externally threaded end, an internally threaded end, and a water passageway;

at least a filter element provided in the water passageway;

an alert device provided on the housing and comprising a temperature sensing element and a temperature indicating element, wherein the temperature sensing element is disposed in the water passageway so as to sense a temperature of water passing through the water passageway, and the temperature indicating element is configured to show different alert messages according to the temperature of the water; and

a cap having an externally threaded end and an internally threaded end, wherein the internally threaded end of the cap is connected with the externally threaded end of the housing so as to guide the water out and retain the at least a filter element.

2. The water filter and alert assembly of claim 1, wherein the at least a filter element comprises one of a filter sponge, a photocatalyst, activated carbon, a perfume essence, porphyritic andesite, and zeolite.

3. The water filter and alert assembly of claim 1, further comprising a plurality of water permeable elements and a sealing ring, wherein the sealing ring and one said water permeable element are provided on a central step portion of the housing, and another said water permeable element is provided on a bottom wall of an inner chamber of the housing, the water permeable elements being configured to retain the at least a filter element and allow passage of the water.

4. The water filter and alert assembly of claim 1, further comprising a power generation unit, wherein the housing is provided on a shower head body, and the power generation unit is provided at a water outlet end of the shower head body and is driven by water pressure in the shower head body to generate power to be supplied to the alert device.

5. The water filter and alert assembly of claim 1, further comprising a safety valve provided in the water passageway, wherein when the temperature of the water reaches a predetermined high temperature value, a valve stem of the safety valve blocks the water passageway and thereby stops the water from flowing out.

6. The water filter and alert assembly of claim 1, further comprising an outgoing water regulating unit, the outgoing water regulating unit comprising:

a casing having a hollow chamber and an internally threaded end, wherein the hollow chamber receives the at least a filter element, and the internally threaded end of the casing is connected with the externally threaded end of the housing;

a water outlet plate formed with a plurality of holes;

a first water distribution plate;

a second water distribution plate; and

an adjustment lever operable to change relative positions between holes of the first water distribution plate and holes of the second water distribution plate and thereby control different water outflow modes.

7. The water filter and alert assembly of claim 1, further comprising a power supply unit provided on the housing, the power supply unit comprising a power plug and a rechargeable battery, wherein the power plug is detachably provided on a lateral side of the housing and is configured to connect external power to the alert device.
