Description

Technical Field

[0001] The utility model relates to the technical field of water filtration and purification, and specifically refers to a direct drinking water purification device. Background Art

[0002] At present, domestic tap water generally cannot be directly drunk because there are still bacteria and the like in the tap water that have not been filtered out, and direct drinking is likely to cause symptoms such as stomachache. At present, most households do not have a special domestic tap water purification device. Therefore, the tap water purification device is a product with relatively high demand.

[0003] Herein, in order to enable domestic tap water to be directly drunk more safely, we have designed a direct drinking water purification device that can be installed between the faucet and the domestic water pipe to effectively filter and purify the domestic tap water. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a direct drinking water purification device that can filter and purify domestic tap water to make it safer to directly drink.

[0005] To solve the above technical problem, the technical solution provided by the utility model is as follows:

[0006] A direct drinking water purification device includes a water purification cylinder and a filter element; the water purification cylinder is a cylindrical structure with both ends closed, and a water inlet is formed on the side wall, and a water outlet is formed at the center of one end wall. The water inlet is connected to the domestic water pipe, and a faucet is connected to the water outlet. The filter element is rotatably arranged in the water purification cylinder and has a cylindrical structure coaxial with the water purification cylinder. The direct drinking water enters the water purification cylinder along a direction tangent to the filter element through the water inlet and is discharged through the water outlet after passing through the filter element, driving the filter element to rotate during the process.

[0007] As an improvement, the filter element includes a PP cotton filter layer, an activated carbon filter layer, a fiber filter membrane, end caps, and a dial plate; the PP cotton filter layer, the activated carbon filter layer, and the fiber filter membrane are all cylindrical structures and are compounded together from the outside to the inside in sequence to form a composite filter layer. The end caps are ring structures with a U-shaped cross-section, and a pair of them are arranged mirror-symmetrically front and back. Both ends of the composite filter layer are respectively nested in the two end caps, and a dial plate fixedly connected between the two end caps is arranged outside the composite filter layer. A plurality of dial plates are evenly arranged along the circumferential direction of the end caps. Through the cooperation of the PP cotton filter layer, the activated carbon filter layer, and the fiber filter membrane, the domestic tap water can be filtered and purified to make it safer to directly drink.

[0008] As an improvement, it further includes bearings. Sleeve rings integrally formed on the inner walls at both ends of the water purification cylinder are respectively arranged on the inner sides of the two end caps, and the end caps are connected to the sleeve rings through bearings. This makes it easier for the filter element to be driven to rotate by the water flow.

[0009] The advantages of the present utility model compared with the prior art are as follows:

[0010] 1. When the present utility model is in use, after domestic tap water enters the water purification cylinder, it can be filtered successively by the PP cotton filter layer, the activated carbon filter layer and the fiber filter membrane, effectively filtering and purifying the domestic tap water, so that it is safer to drink directly.

[0011] 2. When the present model is in use, after water enters the filter cylinder, it can drive the filter element to rotate, so that filter residues are not easily attached to the filter element, and thus it is not easy to cause the filter element to be blocked. BRIEF DESCRIPTION OF THE DRAWINGS
