Description

Technical Field

[0001] The utility model application relates to the technical field of water purifier filter elements, and specifically to a water purifier filter element with a descaling function. Background Art

[0002] The filter element of a water purifier generally contains KDF and activated carbon. The filter element is used to purify polluted water to the state required for production and life, that is, to make the water reach a certain degree of cleanliness, remove solid particles in the water, kill bacteria, and filter out harmful chemical components.

[0003] After a period of use, impurities in the filtered water will accumulate inside the water purifier filter, which can easily cause the water purifier filter to become blocked, resulting in slow water flow or even no water flow. Existing water purifier filter cartridges generally do not have a descaling function, which makes it impossible to remove the dirt filtered by itself. They need to be disassembled for cleaning or replacement, reducing the practicality of the water purifier filter cartridge. Summary of the invention

[0004] In order to solve the problem that the existing water purifier filter element does not have a descaling function during use, resulting in inconvenient maintenance, the utility model provides a water purifier filter element with a descaling function to solve the above problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A water purifier filter with a descaling function comprises a filter element body and a supporting cylinder plate, the upper and lower ends of the filter element body are both fixed with supporting cylinder plates, a water inlet is fixed through the top of the upper supporting cylinder plate, a filter chamber is opened inside the filter element body, and an impeller is arranged at one end of the filter chamber close to the water inlet, the impeller is loaded on a mounting bracket, and the outer edge of the mounting bracket is fixed to the impeller chamber wall, a rotating shaft is fixed to the bottom of the impeller, and the rotating shaft is rotatably connected to the mounting bracket through a bearing, a descaling scraper is symmetrically fixed to one end of the rotating shaft that passes through the bottom of the mounting bracket, and a filter cartridge is detachably connected to the inside of the filter element body below the descaling scraper.

[0007] Furthermore, the filter chamber is configured as a cylinder, and the height of the two descaling scrapers is equal to the height from the rotating shaft to the filter cartridge.

[0008] Furthermore, a reinforcing connecting rod is fixed between the middle parts of the two descaling scrapers, and the width of the reinforcing connecting rod is less than one tenth of the width of the filter chamber.

[0009] Furthermore, the two descaling scrapers are both arranged in an inverted "L" shape, and the outer surfaces of the two descaling scrapers are both slidably fitted with the inner wall of the filter chamber.

[0010] Furthermore, a collecting cylinder is fixed at the bottom of the filter cylinder, and the collecting cylinder is threadedly connected to the inner part of the supporting cylinder plate, a rotating block is fixed to one end of the collecting cylinder extending to the outer side of the supporting cylinder plate, and a snap-fit ​​groove cooperating with the filter cylinder is opened at the bottom of the filter element body.

[0011] Furthermore, the outer surface of the collecting cylinder and the inner circle of the supporting cylinder plate below are provided with mutually matching threads, and the diameter of the rotating block is larger than the diameter of the collecting cylinder.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, the water wheel is driven to rotate by the water flow, and the descaling scraper is driven to rotate. When the descaling scraper rotates, the dirt inside the filter chamber is scraped off to avoid clogging of the filter chamber. This solves the problem that the existing water purifier filter element does not have a descaling function during use, causing inconvenience in maintenance, and greatly improves the practicality of the water purifier filter element and the convenience during maintenance.

[0014] 2. In the utility model, through the detachable design of the filter cartridge, when a lot of dirt is collected in the filter cartridge and the collection cartridge, the filter cartridge can be taken out for cleaning by twisting the rotating block, making it more convenient to maintain the filter element of the water purifier.
