Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

The first embodiment is as follows: the limiting part (2) is formed by processing a high-elasticity spring steel sheet, and after the spring steel sheet is pressed into the liquid drainage groove (8), pressure is exerted on the inner wall of the liquid drainage groove (8), so that the spring steel sheet is prevented from slipping. The enclosure (1) comprises two circular tables formed by rolling punched sheets, wherein the two circular tables are nested with each other to form a two-section telescopic sleeve. The diameter of the upper edge of the lug is matched with the diameter of the filter element, the lower edge of the lug is opened to form an unsealed circular ring, and after the lug is pressed into the liquid drainage groove (8), the lug is tightly attached to the inner wall of the liquid drainage groove (8) by virtue of the elasticity of the lug, so that the lug (4) can move upwards and can be blocked by the limiting piece (2). And the surface of the positioning piece is tightly attached to the positioning piece (2) to ensure that no slag leakage occurs. Surround (1) bottom is equipped with two at least lugs (4), goes up along having flexible cyclic annular interior protruding (6), hugs closely the filter core, provides frictional force, and when the filter core was taken out from flowing back recess (8), the surround is drawn the recess under the upward frictional force effect that protruding (6) provided in flexible cyclic annular, upwards stretches out, and the filter core surface is scraped by the thin slice ring on the surround along and is cleared up the residue simultaneously. When the lug (4) at the lower part of the surrounding part (1) is blocked by the lower edge of the limiting part (2), the filter element leaves the groove, the surrounding part (1) stops above the liquid drainage groove (8), the punched salient point (5) is clamped on the limiting part (2) and does not fall back to the liquid drainage groove (8), so that a blocking barrier is formed above the groove opening, liquid flows into the liquid drainage groove (8) from the fine hole of the surrounding part (1), and residues are blocked in the liquid storage tank. When the filter element is emptied and then is placed back into the drainage groove (8), the upper edge convex part of the filter element can press the surrounding part (1) to move downwards, so that the surrounding part (1) falls back into the groove. Meanwhile, the limiting piece (2) can scrape residues on the outer surface of the surrounding piece (1) to prevent blockage, and when the surrounding piece (1) is composed of more than two cylindrical sleeves, the innermost sleeve is directly pulled when the filter element is taken out. Thereby driving the second and third sleeves in a gradual manner. And separating the filter element from the sleeves until the three sleeves are completely extended. When the cartridge is replaced, the first one is entered first until the three-section sleeve is fully pressed into the recess. Scene in actual use: the filter core is plugged up, and the drainage is slow, treats that the water level is less than the height that surround (1) stretches out, takes out the filter core and pours, and surround (1) continues to filter in flowing back recess (8) top this moment, and high-speed flowing back, when putting back the filter core, surround (1) outward appearance is scraped totally by locating part (2), and the filter core surface is scraped totally by the surround. The method realizes a plurality of actions: 1 deslagging, 2 high-speed liquid discharge and 3 scraping a filtering surface.

Embodiment example two: the spring is in the same place with the bonding of flexible tubulose gauze, and integrative cylinder shape is compressed in flowing back recess by the filter core, and when the filter core was taken out in following the flowing back recess, pressure was relieved, and the spring bounces, and the gauze cylinder forms the cylinder shape at flowing back recess oral area and encloses the fender face, prevents that the residue from getting into the leakage fluid dram, simultaneously quick flowing back.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
