Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and more specifically, to a filter faucet with a self-cleaning effect. Background Technology

[0002] Water from water treatment plants undergoes a series of treatments before leaving the plant, but the transport pipes themselves may be aging or corroded, and the water may be subject to secondary pollution. Therefore, installing a filter in the faucet can further remove fine impurities and specific pollutants, purifying the water quality.

[0003] As shown in the existing filter faucet, "as in application number: CN201922456714.4, an improved filter faucet", the "upper part of the filter seat is screwed to the filter cover", that is, the filter element is cleaned by removing the filter cover. Although the filter element can be cleaned by removing the filter cover, the process is cumbersome and the filtration efficiency may be reduced due to poor cleaning results. Utility Model Content

The upper end of the faucet body is provided with a handle for adjusting water pressure. One end of the faucet body is provided with a water outlet for discharging filtered tap water. The lower end of the faucet body is provided with a self-cleaning filter device for filtering impurities in the water and having a self-cleaning effect. The lower end of the faucet body and located to the right of the self-cleaning filter device is provided with a liquid inlet for dispensing ultrasonic cleaning fluid. The lower end of the faucet body and located below the self-cleaning filter device is provided with a drain outlet for discharging filtered wastewater.

[0006] As a preferred embodiment of this utility model, the self-cleaning filter device is provided with a pulse generator for generating high-frequency fixed pulses at its upper end and above the faucet body. The pulse generator generates 55kHz high-frequency pulses for transmission to the transducer. The pulse generator is equipped with a switch for turning on the generator. Below the pulse generator and inside the faucet body, a transducer is connected for converting the high-frequency pulse signal into ultrasonic energy. A sealing ring is provided at the connection between the transducer and the faucet body to prevent water leakage.

[0012] Example 1 like Figs. 1 to 2 As shown, this utility model proposes: a filter faucet with self-cleaning effect, including a faucet body and a self-cleaning filter device. The present invention proposes a self-cleaning filter faucet, comprising a faucet body and a self-cleaning filter device. The upper end of the faucet body is provided with a handle for adjusting water pressure, one end of the faucet body is provided with a water outlet for discharging filtered tap water, the lower end of the faucet body is provided with a self-cleaning filter device for filtering impurities in the water and having a self-cleaning effect, the lower end of the faucet body and the right side of the self-cleaning filter device is provided with a liquid inlet for supplying ultrasonic cleaning fluid, and the lower end of the faucet body and the lower side of the self-cleaning filter device is provided with a drain outlet for discharging filtered wastewater; the lower outer layer of the self-cleaning filter device is provided with a PP cotton filter layer, the lower inner layer of the self-cleaning filter device is provided with an activated carbon filter layer, and the upper ends of the PP cotton filter layer and the activated carbon filter layer are provided with a fixing frame for fixing the filter element layer and restricting the water flow direction. A pulse generator for generating a 55kHz high-frequency fixed pulse is located at the top of the self-cleaning filter and above the faucet body. The pulse generator is equipped with a switch for turning it on. Below the pulse generator and inside the faucet body, a transducer for converting the high-frequency pulse signal into ultrasonic energy is connected. A sealing ring to prevent water leakage is provided at the connection between the transducer and the faucet body. The faucet body shell is made of a corrosion-resistant material.

[0013] Working principle When the handle for adjusting the water pressure is turned, unfiltered tap water is transported through the pipe into the faucet body. Due to the fixed frame restricting the direction of water flow, the water can only flow towards the filtration device. When the water flows through the PP cotton filter layer with a filtration precision of 1-50 microns, it can effectively remove suspended solids, particulate matter, and larger impurities from the water. After passing through the PP cotton filter layer, the water flows through the activated carbon filter layer with a high filtration precision (up to 0.1 microns), which can effectively remove bacteria, viruses, and tiny particulate matter. Finally, under the restriction of the fixed frame, the filtered tap water flows to the outlet for people to use.

[0014] When the filter screen is clogged and needs cleaning, first turn the handle to the off position to stop the tap water flow. Then, add an acidic ultrasonic cleaning solution with a 1:30 ratio to the inlet. This effectively dissolves limescale and minerals while avoiding excessive corrosion of the activated carbon. After adding the ultrasonic cleaning solution, press the pulse generator switch. The generator emits a fixed high-frequency pulse signal, which is then converted into ultrasonic energy by the transducer connected to the lower end of the generator. This energy is transmitted to the cleaning solution, causing it to vibrate at high frequency. This vibration generates numerous tiny bubbles that impact the filter element, effectively removing dirt from its surface. Furthermore, the faucet housing is made of corrosion-resistant material, preventing damage from the acidic ultrasonic cleaning solution over time.

[0015] When cleaning is complete, turn the handle to the open position to allow tap water to flow, and open the drain to discharge the acidic ultrasonic cleaning solution in the filter device along with the water flow. There is no need to manually disassemble the filter screen for cleaning, thus achieving the self-cleaning effect of the filter faucet.

[0016] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
