Description

Technical Field

[0001] This utility model relates to the field of water heater technology, specifically to a scale-proof and corrosion-proof water filtration device for household water heaters. Background Technology

[0002] A water heater is a device that uses various physical principles to raise the temperature of cold water to hot water within a certain period of time. Water heaters can be classified according to different principles, such as electric water heaters, gas water heaters, solar water heaters, magnetic water heaters, air source water heaters, and heating water heaters. Their structure consists of a cold air generation section and a hot water generation section. The main function of a water heater is to produce hot water.

[0003] For example, the Chinese Utility Model Application provides "A Novel Wall-Mounted Water Heater with Multiple Repeated Protection Functions," with publication number CN216203731U. This application includes an inlet pipe, an outlet pipe, and a main body shell. The inlet pipe and outlet pipe are installed at the lower end of the main body shell. The inlet pipe is located on the right side of the outlet pipe, and a filter device passes through the lower end of the outlet pipe. The filter device includes a shell A, a filter screen, and a shell B. The desired temperature is adjusted by a temperature regulator, and the internal temperature is observed by a temperature indicator. The indicator light will stay on until the water heats up to the set temperature. Then, tap water entering through the inlet pipe flows through the main body shell. After the water is heated internally, it flows out of the outlet pipe and then passes through the filter device. The filter screen in the filter device can filter out the scale in the hot water. After a period of use, the outer casing B can be opened, the filter screen can be removed and cleaned, and then rotated back on to ensure a good filtration effect and not affect the water flow rate. Although the water heater in the above technology can filter the scale in the water discharged from the outlet pipe, it cannot filter the scale in the water flowing through the inlet pipe. As a result, a certain amount of scale enters and adheres to the inside of the water heater, causing some corrosion to the inside of the water heater and affecting its service life. Utility Model Content

[0004] The purpose of this invention is to provide a scale-proof and corrosion-proof water filtration device for household water heaters. This device effectively filters and purifies the water supplied to the water heater, reducing scale buildup and ensuring long-term use. It solves the problem in the aforementioned technologies where water heaters, while able to filter scale from the water discharged through the outlet pipe, cannot filter scale from the water flowing through the inlet pipe, leading to scale entering and adhering to the interior of the water heater, causing corrosion and impacting its lifespan.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scale-proof and corrosion-proof water filtration device for household water heaters, comprising a filter box, a water heater inlet pipe fixedly connected to the upper left side of the filter box, an RO reverse osmosis membrane fixedly installed between the right side of the water heater inlet pipe and the upper right side of the filter box cavity, a fixed cylinder fixedly connected to the middle of both sides of the filter box cavity, a protective cylinder movably connected between the outer surfaces of the two fixed cylinders, a guide block fixedly connected to the left end of the top of the protective cylinder cavity, a cleaning brush fixedly connected to the top of the outer surface of the protective cylinder, three cleaning brushes, the surface of the cleaning brushes movably connected to the outer surface of the RO reverse osmosis membrane, a drive motor fixedly installed to the middle of the right side of the filter box cavity, a rotating shaft fixedly installed at the output end of the drive motor, a rotating cylinder fixedly connected to the left side of the rotating shaft, guide grooves formed around the rotating cylinder, and the lower end of the guide block movably connected to the surface of the guide grooves.

[0008] As a preferred embodiment, a rubber ring is fixedly connected to the outer surface of the fixed cylinder, and the inner cavity of the protective cylinder is movably connected to the surface of the rubber ring.

[0009] As a preferred embodiment, a support shaft is fixedly connected to the left side of the rotating drum, and the left side of the support shaft is movably connected to the middle of the left side of the filter box cavity via a bearing.

[0010] As a preferred embodiment, a water supply pipe is fixedly connected to the middle of the top of the filter box, and a sealing ring is fixedly connected to the top of the water supply pipe.

[0011] As a preferred embodiment, mounting brackets are fixedly connected to both ends of the back of the filter box, and mounting holes are provided at both ends of the mounting brackets.
