Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The composite filter element of the water purifier capable of stripping and decontaminating comprises an active carbon filter stick 2 as shown in fig. 1 to 3, wherein the active carbon filter stick 2 is a sintered carbon stick, the filter element of the utility model further comprises a filter cotton belt 11, and as shown in fig. 1 and 4, the filter cotton belt 11 is spirally wound to form a filter cotton cylinder 1, and the filter cotton cylinder 1 in fig. 1 is shown to be partially unfolded, and the filter cotton cylinder 1 is in a winding state in the actual use process of the filter element. As shown in fig. 4, the filter cotton tape 11 is formed with tear lines 101, and the tear lines 101 are circumferentially spaced apart (so-called "circumferential" is for the axis of the filter cotton cartridge 1), in other words, the tear lines 101 are spaced apart along the length of the filter cotton tape 11 when the filter cotton tape 11 is in an unreeled state. For example, the frangible line 101 may be an indentation structure, but is not completely broken, in other words, the frangible line 101 is a linear portion of the filter belt 11 that is relatively weak. As shown in fig. 2 and 3, the filter cotton canister 1 is sleeved outside the activated carbon filter stick 2, and it can be understood that the filter cotton tape 11 is wound outside the activated carbon filter stick 2. Since the filter cartridge 1 has a multi-layer structure, the filter cartridge 1 has a large amount of dirt.
When the composite filter element is installed in a tap water purifier for use, water flows pass through the filter cotton cylinder 1 and then pass through the activated carbon filter stick 2, and the water flows are subjected to double filtration, so that the filter cotton cylinder 1 can intercept impurities with large particles in the water flow, the fine gap structure of the activated carbon filter stick 2 is prevented from being blocked easily, the filter effect of the composite filter element is durable, and the activated carbon filter stick 2 is mainly used for adsorbing abnormal odor in water, residual chlorine in water, partial heavy metal and the like; compared with the traditional ceramic filter element, the composite filter element has good filtering effect on residual chlorine, and the filter cotton cylinder 1 is relatively difficult to block, so that the surface of the ceramic filter element is prevented from being cleaned frequently by a user, and the composite filter element is convenient to use. As shown in figure 1, when the filter element is used for a period of time, the surface of the filter cotton cylinder 1 is inevitably accumulated with large particles and impurities, so that the water passing capacity of the filter cotton cylinder 1 is reduced, as shown in figure 1, a user can spread a section of filter cotton belt 11 of the filter cotton cylinder 1, then tear off the filter cotton belt 11 positioned on the surface of the filter cotton cylinder 1 along an easy-to-tear line 101, and then the filter element is installed on a tap water purifier for use, so that the surface layer filter cotton belt 11 with reduced performance can be quickly peeled off, the purpose of quickly decontaminating and cleaning the composite filter element is achieved, and the composite filter element can maintain long-term better service performance, so that the composite filter element is convenient to clean; after the surface layer filtering cotton belt 11 is peeled off for a plurality of times, the thickness of the filtering cotton barrel 1 along the radial direction is obviously small, the composite filter element only needs to be scrapped, and a new composite filter element is replaced to the tap water purifier.
Further, as shown in fig. 4 and 5, the easy-to-tear line 101 includes through holes 1011, and the through holes 1011 are arranged at intervals along the easy-to-tear line 101, so that the easy-to-tear line 101 forms a weak structure, and a user can easily tear the filter cotton tape 11 along the easy-to-tear line 101.
Further, as shown in fig. 4, the easy-to-tear line 101 is parallel to the axis of the filter cartridge 1, in other words, the easy-to-tear line 101 is perpendicular to the edge line of the filter cotton tape 11, which is convenient for the user to tear the filter cotton tape 11, and makes the structure of the remaining filter cartridge 1 regular and easy to be installed back into the tap water purifier.
Further, since the filter belt 11 is a PP melt blown filter belt, the filter cartridge 1 has a large filter flow rate, a small pressure difference, and good chemical stability.
Further, as shown in fig. 1 to 3, the composite filter element of the present utility model further includes an upper cover 3 and a base 4, the upper cover 3 and the base 4 are injection molded parts, the lower end of the activated carbon filter rod 2 is connected with the base 4 in a mounting manner, as shown in fig. 7, the base 4 is formed with a water outlet 401, a carbon rod water passage 201 is formed in the activated carbon filter rod 2, specifically, the carbon rod water passage 201 is a circular through hole, the upper cover 3 seals the upper end of the carbon rod water passage 201, that is, the upper cover 3 seals the upper end of the carbon rod water passage 201, the water outlet 401 is communicated with the lower end of the carbon rod water passage 201, the filter cotton cylinder 1 is arranged between the upper cover 3 and the base 4, and the upper cover 3 and the base 4 play an axial positioning role on the filter cotton cylinder 1. As indicated by the dashed arrows in fig. 2, the water flows into the filter cotton cartridge 1 in the radial direction, then flows through the activated carbon filter stick 2, is double-filtered by the filter cotton cartridge 1 and the activated carbon filter stick 2, then enters the carbon rod water passage 201, and finally is discharged from the water outlet hole 401.
Further, as shown in fig. 6, an upper positioning plug 32 is formed at the lower side of the upper cover 3, as shown in fig. 2, the upper positioning plug 32 is inserted into the upper end portion of the carbon rod water channel 201, as shown in fig. 6, the outer wall of the upper positioning plug 32 is an inverted conical surface, that is, the outer shape of the upper positioning plug 32 is in a shape of big end down, so that the upper positioning plug 32 is conveniently inserted into the upper end portion of the carbon rod water channel 201, and the upper end edge of the carbon rod water channel 201 and the outer wall of the upper positioning plug 32 can be in close contact, which is beneficial to positioning the activated carbon filter rod 2, and raw water is prevented from directly entering the carbon rod water channel 201 through the upper end of the carbon rod water channel 201.
