The invention discloses an external pressing type filter device convenient for replacing an external filter layer and a filter. The filter device comprises a filter element, wherein an external filter layer is movably covered on the outer surface of the filter element, two ends of the filter element are respectively provided with a sealing locking structure for fixing the external filter layer, and the sealing locking structures are movably arranged at two ends of the filter element. The filter comprises the filter device and a shell body, wherein the shell body comprises an upper shell body, a lower shell body and a locking structure; the upper shell body is provided with an upper positioning column matched with a positioning hole in an upper end cover, and the positioning column is provided with a water outlet; the lower shell body is provided with a lower positioning column matched with a lower positioning hole in a lower end cover. The filter device disclosed by the invention is simple in structure and convenient for operation; a user can independently replace the external filter layer without equipping professional tools, and a professional maintenance worker is not needed, so that the maintenance cost is saved; and the filter element is sufficiently utilized, so that the service life is prolonged, the cost is saved, and the waste is reduced.
Description
Technical field [0001] The invention belongs to the technical field of water purification filter devices, and in particular relates to an external pressure type filter device and a filter that facilitate the replacement of an outer filter layer. Background technique [0002] With the improvement of people's living standards, the quality requirements for domestic water are getting higher and higher. In the purification of drinking water, filter rods are a widely used filter device, especially when purifying on the basis of tap water. Filter rods can achieve the ideal purification effect. Many existing filter rods are rod-shaped with a single material. If multi-stage purification is required, multiple filter rods of different materials are required to be used in combination, which makes drinking water settings complicated and bulky. [0003] There are also some filter rods on the market that combine multiple filter materials. One filter rod can achieve multi-stage filtration and simp...
