Abstract
The utility model belongs to the technical field of pre-filters, and particularly relates to a filter element cleaning structure of a pre-filter, which comprises a cylinder and a filter element arranged in the cylinder, wherein the filter element comprises a filter screen framework and a filter screen arranged on the outer surface of the filter screen framework; more than one scraping mark is arranged on the inner wall of the cylinder; and one side of the scraping mark is placed against the filter screen. According to the filter element cleaning structure provided by the utility model, when the filter element needs cleaning, the filter element is rotated only without taking out the whole, the scraping mark can scrape off dirt on the filter screen, and the dirt is discharged from a discharge outlet at the lower end of the cylinder; and meanwhile, the scraping mark is soft plastic or rubber which does not damage the filter screen, thereby guaranteeing the service life of the pre-filter.
Description
Technical field
The utility model belongs to the fore filter technical field, is specifically related to a kind of filter core cleaning structure of fore filter.
Background technology
Fore filter in use for some time, filter core can accumulate some dirts, at this moment, just need filter core is cleaned, at present, the mode of the cleaning filter core that people commonly use is the cylindrical shell with the whole taking-up fore filter of filter core, and scrub with the hairbrush of daily laundry usefulness, there is hidden danger in this operation, may cause the destruction of filter screen in the process that hairbrush is scrubbed, thereby affects the filtering function of filter.
Summary of the invention
In order to overcome above shortcomings part in the prior art, it is a kind of simple in structure, safe and reliable that the purpose of this utility model is to provide, and cost is lower, and practicality is good, the filter core cleaning structure of the fore filter of easily accepting for market.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme:
The filter core cleaning structure of fore filter, comprise cylindrical shell and be arranged on the interior filter core of cylindrical shell, filter core comprises filter screen skeleton and the filter screen that is arranged on filter screen skeleton outer surface, is provided with above together scraping article on the inwall of described cylindrical shell, and a side of described scraping article is against on the filter screen.
Described scraping article is T-shaped, forms the Access Division that described scraping article is installed on the inwall of described cylindrical shell.
Described scraping article is flexible plastic or rubber.
Compared with prior art, the utlity model has following outstanding advantages and effect:
The utility model is so that filter core need to clean the time, need not whole the taking-up, only need to rotate filter core, scraping article can scrape the dirt on the filter screen, get final product in the sewage draining exit discharge by the cylindrical shell lower end, scraping article is flexible plastic or rubber simultaneously, and it can not damage filter screen, has guaranteed the service life of fore filter.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the filter core cleaning structure of fore filter, comprise cylindrical shell 5 and be arranged on the interior filter core of cylindrical shell, the filter screen 4 that filter core comprises filter screen skeleton 3 and is arranged on filter screen skeleton 3 outer surfaces, be provided with above together scraping article 7 on the inwall of described cylindrical shell 5, one side of described scraping article 7 is against (length of scraping article can increase or shorten according to design, and only a part of surface of need scraping article is squeezed on the filter screen and gets final product) on the filter screen 4.Filter screen skeleton 3 inside are water-purifying cavity 1, and it is communicated with delivery port, between filter screen and the cylindrical shell be former water cavity 2(namely, water cavity from the beginning), former water cavity connects water inlet.
Described scraping article 7 is T-shaped, forms the Access Division that described scraping article 6 is installed on the inwall of described cylindrical shell 5.
