Description

a water purifier

technical field

The present application relates to the technical field of cleaning filter elements of water purifiers, in particular to a water purifier.

Background technique

Water purifiers are also called water purifiers and water quality, which perform deep filtration and purification treatment on water quality according to the requirements for water use. The water purifier usually referred to generally refers to a small purifier for household use. The function of the water purifier is to remove the impurities, heavy metals, bacteria, sediment, rust, microorganisms, etc. in the filtered water. Residual chlorine can improve the taste of water at the same time. After the water purifier is used for a long time, the filter element inside the water purifier will be blocked due to the accumulation of impurities in the water, which will affect the water purification and filtration effect. At this time, the filter element needs to be replaced or cleaned.

For example, in the existing Chinese patent whose publication number is CN114538537A, it discloses a box-type water purifier, which includes a water purification box, a pressure pump, a filter body and a filter element, and the water inlet of the water delivery pipe inside the filter body is rotatably connected. There is a rotating shaft, one end of the rotating shaft close to the water inlet is fixedly connected to the facade fan, the other end is fixedly connected to the bevel gear, and the inner wall above the filter body is rotatably connected to the swivel body, and the inner ring of the swivel body is provided with teeth that match the bevel gear. The lower surface of the swivel body is fixedly connected with a scraper that is in contact with the inner wall of the filter, and the side of the scraper is fixedly connected with a brush. Through the above-mentioned prior art, the pressure pump pumps water into the water purification tank through the water delivery pipe, and then sends the water to the inside of the filter body through the water delivery pipe, and is filtered by the filter element inside the filter body, so that impurities and water in the water are separated and then passed through the water delivery pipe It is sent to the water outlet for users to use. When the water enters the inside of the filter body, it will impact the fan surface of the facade fan, which makes the facade fan rotate under the action of water, so that the shaft and bevel gear start to rotate under the drive of the facade fan , because the bevel gear cooperates with the rack on the swivel body, the swivel body rotates along the inner wall of the filter. During the rotation of the swivel body, the scraper rod is driven to rotate along the inner wall of the filter, so that the inner wall of the filter can be cleaned. The accumulated impurities are cleaned, and the brush on the side of the scraper can also clean the surface of the filter element.

Yet there is following technical defect in above-mentioned prior art:

When the above prior art works, the water flow drives the scraper to rotate along the inner wall of the filter to clean the inner wall of the filter and the surface of the filter element; the cleaning method is simple and single, although the surface of the filter element can be cleaned, there are still many impurities inside accumulation, and the brush on the side of the scraper rod cannot effectively clean the filter element as a whole.

Because the above-mentioned existing technology cleans the surface of the filter element, it is realized through the operation of the scraper rod driven by the water flow, so that although the scraper rod operates to clean the inner wall of the filter and the surface of the filter element, the synchronous flow of water will also promote the continuous cleaning of the filter element. Filtration operation; on the one hand, the surface of the filter element is simply cleaned, and on the other hand, the impurities in the water continue to adhere and accumulate on the filter element when the filter element is filtering the water flow, resulting in unsatisfactory cleaning results; in addition, the scraper cleans the inner wall of the filter and the filter element Impurities on the surface will be discharged through the water pipe along with the water flow. In the long run, the inner wall of the water pipe will easily adhere to impurities and breed bacteria, which will affect the safety of water use.

Based on this, on the basis of an existing box-type water purifier, in order to overcome the above-mentioned technical defects, there is still room for improvement.
