[0016] The advantages and beneficial effects of the utility model are: providing a filter element cleaning device, which can clean impurities accumulated on the inner wall of the filter element, and can collect the cleaned impurities during the cleaning process, thereby avoiding secondary pollution caused by impurities and avoiding affecting the environment due to cleaning the filter element; and the filter element cleaning device has a simple structure, low cost, easy use and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic diagram of the utility model. DETAILED DESCRIPTION

[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] The specific technical solutions implemented in this utility model are as follows:

[0020] like Figure 1 As shown, a filter element cleaning device is used to clean impurities accumulated on the inner wall of a cylindrical filter element, comprising: a vertical handle 1, and a scraper barrel 2 connected to the bottom end of the handle 1;

[0021] The scraper barrel 2 comprises: a vertical cylindrical main body 21 with a closed bottom and an open top, and a notch 22 provided on the side wall of the main body 21 and extending from the top of the side wall to the bottom of the side wall; the transverse width of the notch 22 gradually decreases from top to bottom along the axial direction of the main body 21 of the scraper barrel 2, and the sideline of the notch 22 is parabolic; the transverse width of the top of the notch 22 is not greater than the inner diameter of the main body 21 of the scraper barrel 2; and the transverse width of the top of the notch 22 is not less than two-thirds of the inner diameter of the main body 21 of the scraper barrel 2; the inner diameter of the main body 21 of the scraper barrel 2 is not greater than the inner diameter of the filter element; the axial length of the main body 21 of the scraper barrel 2 is less than the axial length of the filter element;

[0022] The handle 1 includes: a vertical rod 11 whose bottom end is fixed to the inner bottom wall of the main body 21 of the scraper barrel 2, and a horizontal rod 12 whose middle part is fixed to the top of the vertical rod 11; the vertical rod 11 is coaxial with the main body 21 of the scraper barrel 2; the length of the vertical rod 11 is greater than the axial length of the filter element; the length of the horizontal rod 12 is not less than the outer diameter of the main body 21 of the scraper barrel 2.

[0023] The use principle of the filter element cleaning device of the utility model includes:

[0024] When cleaning the filter element, first take out the cylindrical filter element with impurities accumulated on the inner wall from the filtering device and place it upright, then hold the handle 1 and extend the scraper barrel 2 to the bottom of the filter element, and make the notch 22 of the scraper barrel 2 abut against the inner wall of the filter element, then hold the handle 1 and pull the scraper barrel 2 upward, the scraper barrel 2 moves up and scrapes the inner wall of the filter element, until the scraper barrel 2 is moved up to the top of the scraper barrel 2 above the filter element;

[0025] The scraper barrel 2 is repeatedly operated to move upward and scrape the inner peripheral wall of the filter element; each time the scraper barrel 2 moves upward and scrapes the inner peripheral wall of the filter element, the impurities on the inner peripheral wall of the filter element will be scraped off, and the scraped impurities will fall into the scraper barrel 2 through the notch 22, that is, the scraped impurities will be collected in the scraper barrel 2; by repeatedly operating the scraper barrel 2 to move upward and scrape the inner peripheral wall of the filter element, the impurities on the inner peripheral wall of the filter element can be cleaned, and the cleaned impurities will be collected in the scraper barrel 2;
