The first filter unit 100A, the second filter unit 100B, and the third filter unit 100C are respectively provided, and the following is described by the first filter unit 100A, which is mainly composed of a connecting disc 10 An input plate member 20 and an output plate member 30, wherein the connecting plate member 10 has a connecting plate portion 11 and a disk surface 111 protruding from the connecting plate portion 11 and having a connecting plate extending therethrough. The connecting pipe portion 12 of the guiding duct 121 of the portion 11 and a connecting ring portion 13 protruding from the lower surface 112 of the connecting plate portion 11; in the embodiment, the connecting pipe portion 12 has an externally threaded portion 122.

The input plate member 20 has an input plate portion 21, an input ring portion 22 protruding from the plate surface 211 of the input plate portion 21 and fixed to the connecting ring portion 13, and a through-the-plate portion 21 Another extension tube portion 23 through which the connection tube portion 12B of the filter unit (for example, the second filter unit 100B is exemplified) is protruded from the lower plate surface 212 of the input plate portion 21 and has a through-the input An input pipe portion 24 of the input pipe 241 of the plate portion 21, and a plurality of input pipe portions 24 provided in the input pipe portion 24 and dividing the input pipe 241 into an input slot 2411 and a lower input slot 2412, and each of the inputs The blocking portion 25 has an input hole 251 for communicating the upper input slot 2411 with the lower input slot 2412. In this embodiment, the input ring portion 22 of the input plate member 20 is fixed to the inner annular surface of the connecting ring portion 13. The extension tube portion 23 of the input plate member 20 has an extension 231 protruding from the upper surface 211 of the input plate portion 20; in addition, the extension tube portion 23 has an internal thread 232.

The output plate member 30 is fixed to the upper plate surface 211 of the input plate portion 21 and has a sleeve hole 31 disposed in the extension portion 231 of the extension tube portion 23, and an output column portion 32 enclosing each of the upper input slots 2411, and each of the output column portions 32 has a communication with the upper input slot 2411 In the embodiment, the output plate member 30 further has an output ring portion 33 fixed to the inner surface of the input ring portion 21 of the input plate member 20, and the ring end face 331 of the output ring portion 33 The lower disk surface 112 of the connecting plate portion 11 of the connecting plate member 10 is airtight; in addition, the output hole 321 of the output plate member 30 is disposed opposite to the input hole 251 of the input plate member 21 at a position 180 degrees apart.

It is worth mentioning that, in this embodiment, each of the filtering units is disposed in the filter cylinder 90 and the filter cover 91, and the first filter unit 100A of each of the filter units, the connection tube portion 12 of the connection disc member 10 is connected to the output tube 911 of the filter cartridge cover 91 of the fluid filter. And the outer ring cover of the connecting ring portion 13 of the first filter unit 100A has an inner tube member 92, and the ring portion of the connecting plate portion 11 of the connecting plate member 10 of the first filter unit 100A. The larger than the outer diameter 921 of the inner tubular member 92 is to increase the filtering effect, and the connecting plate portion 11 of the connecting plate member 10 is spaced apart from the inner cylindrical wall surface 901 of the filter cylinder 90 by a gap. The smaller the gap, the filtering effect The better. In addition, the last filter unit (ie, the third filter unit 100C) of each of the filter units, the extension tube portion 23C of the input plate member 20C is sealed by a plug member 96, and the plug member 96 has A plug portion 961 disposed in the extension tube portion 23C, a shielding portion 962 covering the input tube portion 24C of the input plate member 20C, and a guiding groove 963 recessed by the shielding portion 962 are added to Filter the effect.

The above description is the structure and configuration description of each main component of the embodiment of the present invention. As for the efficacy of the embodiment of the present invention, the following description will be made.

First, the assembly cost is low. In the filter group structure of the present invention, the input plate member 20 of each of the filter units is provided with an extension pipe portion 23 for another filter list. The connecting pipe portion 12B of the connecting plate member 10B is connected. This embodiment is exemplified by a screw connection. Therefore, it is quite convenient in assembly, and it is only necessary to align the connecting pipe portion 12B of the connecting plate member 10B with another filter. After the extension tube portion 23 of the input plate member 20 of the clean unit 100A is locked, the assembly can be completed, and the assembly can be completed without tools or screws, and the assembly cost is relatively low.

Second, the production cost is low. Due to the filter group structure of the present invention, each of the filters The unit is composed of a connecting plate member 10, an input plate member 20, and an output plate member 30. Therefore, only a single mold can be used for the production, thereby changing the filter according to the use requirements. The number of net units eliminates the cost and time required to recreate the various sizes to really reduce production costs.

Third, the assembly is convenient. Since the extension tube portion 23 of the input plate member 20 has a convex portion The extension portion 231 of the plate surface 211 is disposed on the input plate portion 20, so that when the output plate member 30 is assembled with the input plate member 20, the extension portion 231 of the extension tube portion 23 is guided. The sleeve hole 31 of the output plate member 30 can be quickly placed on the extension tube portion 23 of the input plate member 20 to complete the assembly of the two to achieve the convenience of assembly.

In the above, the above embodiments and the illustrations are only the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the equal variations and modifications made by the scope of the present invention. It should be within the scope of the patent of the present invention.
