A filter device 100 according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 4.

As shown in fig. 1-4, the filter device 100 includes a housing 110 and a filter cartridge 120. The housing 110 is mainly used to house a filter cartridge 120 as a core member of the filter device 100. Illustratively, the housing 110 may be formed from a plurality of components that are joined together, such as by welding, plugging, and the like. The housing 110 is provided with a water inlet and a water outlet. Alternatively, the housing 110 may be formed of a single piece. In an exemplary embodiment, the filter element 120 may include a rolled reverse osmosis membrane (RO) and a center tube. The raw water introduced into the housing 110 from the water inlet flows along the outer circumferential surface of the rolled reverse osmosis membrane to the end surface of the rolled reverse osmosis membrane far from the water inlet, and enters the rolled reverse osmosis membrane from the end surface. The central channel of the roll-type reverse osmosis membrane is a pure water channel, and the central tube is embedded in the pure water channel so as to lead out pure water. The central tube is communicated to the water outlet.

Filter device 100 also includes a first barrier 130 and a second barrier 140. First barrier 130 and second barrier 140 fit over filter element 120. Inner peripheral edges of first barrier 130 and second barrier 140 are sealingly connected to cartridge 120. First barrier 130 and second barrier 140 may be disposed over filter element 120 in an interference fit to ensure water tightness at the connection. Exemplarily, the first barrier 130 and the second barrier 140 may be made of a material having a certain elasticity, such as rubber or the like. Alternatively, the first barrier 130 and the second barrier 140 may also be made of a rigid material, in which case the sealing of the first barrier 130 and the second barrier 140 to the filter cartridge 120 at the connection may be achieved, for example, by a seal or sealant, etc. Peripheral edges of first barrier 130 and second barrier 140 are sealingly connected to housing 110. Similarly, the sealing of first barrier 130 and second barrier 140 to housing 110 at the connection may be achieved by an interference fit, a seal, and/or a sealant. First barrier 130 and second barrier 140 are disposed spaced apart from each other. In this way, a scale inhibitor chamber is formed between the first barrier 130 and the second barrier 140. The scale inhibitor cavity is annular. The portion of the housing 110 between the first barrier 130 and the second barrier 140 forms an outer peripheral wall of the annular scale inhibitor chamber, and the portion of the filter element 120 between the first barrier 130 and the second barrier 140 forms an inner peripheral wall of the annular scale inhibitor chamber. The first blocking member 130 and the second blocking member 140 are respectively provided with through holes 132 and 142, as shown in fig. 2 and 4, respectively serving as a water outlet and a water inlet of the scale inhibitor chamber.

The scale inhibitor cavity is internally provided with a scale inhibitor 150. The scale inhibitor 150 may be a substance that controls the scaling of inorganic salts on the surface of the filter element 120 over a wide range of concentrations. The scale inhibitor 150 is mainly used for interacting with metals such as calcium, magnesium, manganese and the like in raw water, reducing the content of the metal ions in the raw water, and preventing the scale from forming on the surface of the filter element 120 to reduce the service life of the filter element 120. Different types and/or components of scale inhibitors can be selected for different filter elements. For the filter element formed by the reverse osmosis membrane, various antisludging agents for the reverse osmosis membrane which are commercially available at present can be selected as the antisludging agent. The utility model discloses do not intend to restrict the type and the composition of antisludging agent as long as can realize its function.

The utility model discloses utilize long and narrow space between casing 110 and the filter core 120 to form the antisludging agent chamber for the antisludging agent chamber has bigger capacity, and then can place a large amount of antisludging agents, can be by the antisludging agent of sufficient volume to handle before raw water gets into filter core 120. In addition, the space is longer along the water flow direction, so that the time of the raw water acting with the scale inhibitor in the scale inhibitor cavity is prolonged, the raw water and the scale inhibitor can be fully soaked, and the reaction is more full. In addition, because the space of the scale inhibitor cavity is larger, the scale inhibitor can have enough space to fully rotate, thereby having higher reaction efficiency. Therefore, the utility model provides a filter equipment 100 can reduce the hardness of raw water by a wide margin, is difficult to consequently block up the filter core 120 of rear end, even use in the higher area of quality of water hardness, filter core 120 also can keep longer life to protect the waste water valve of filter core 120 rear end effectively, make it difficult stifled hole. In addition, the filter device 100 utilizes the filter element 120 and the housing 110 to form the scale inhibitor chamber together with the first blocking member 130 and the second blocking member 140, so that the number of parts of the filter device 100 is small, the structure is simple, and the processing cost can be reduced.

Further, the position of at least one of the first barrier 130 and the second barrier 140 on the cartridge 120 is adjustable. The position adjustable barrier can be placed over any position of the filter element 120. In this way, adjusting the position of at least one of the first blocking member 130 and the second blocking member 140 can change the axial dimension (along the direction of the central axis P-P in fig. 2) of the scale inhibitor chamber to meet the requirements of different regions, different water qualities and/or different filter elements on the addition amount of the scale inhibitor. Optionally, a stop may be provided for either the first barrier 130 or the second barrier 140, such that one of the barriers has a fixed position and the other is adjustable in position on the cartridge 120. Optionally, the position of both the first barrier 130 and the second barrier 140 on the cartridge 120 may be adjustable. Because the capacity of the scale inhibition cavity is adjustable, a person skilled in the art can properly set the distance between the first blocking member 130 and the second blocking member 140 according to the addition amount of the scale inhibitor, the space required by the rotation of the scale inhibitor and the like, so that the scale inhibitor can fully play a role, and the service life of the filter element 120 is prolonged.
