In order to further understand the functions produced by the coordination of the various components of the present invention, the use of technical means, and the expected effects, it will be explained as follows. It is believed that the present invention can be understood more deeply and specifically.

As shown in FIG. 3 , before the covering part 30 of the upper cover 100 is formed, the positioning columns 20 are pre-assembled on the core plate 10 , that is, each upper positioning block 21 is provided with the bottom of the sleeve portion 213 The end is passed through the corresponding positioning hole 14 until the bottom surface of the top section 212 abuts against the top surface 12 of the core board 10, and then each lower positioning block 22 is assembled on the core board 10 from the bottom surface 11 , until the abutting surface 222 abuts against the bottom surface 11 , the engaging portion 224 and the sleeve portion 213 are also fitted together, and all the positioning posts 20 are assembled on the core board 10 .

As shown in Figure 2, Figure 4 and Figure 5, during the injection molding process of the upper cover 100, the positioning columns 20 are used to insert and fix the core plate 10, and the top surface 214 of the positioning columns 20 is aligned with the bottom surface 221. Being able to be positioned against the inside of the injection mold cavity can improve the core plate 10 of the cladding 30 to produce a better positioning effect during the injection process. That is to say, the positioning columns 20 are used to pre-embed and fix the core plate 10, so that the core plate 10 of the metal sandwich can be completely and stably fixed on the plastic cladding part 30 (sandwich structure), avoiding high pressure extrusion during injection molding. The material impact phenomenon leads to unstable phenomena such as metal interlayer movement.

After the upper cover 100 is manufactured, the outline of the peripheral surface 13 of the core plate 10 does not exceed the outline of the outer peripheral surface 331 of the cladding member 30 . The core plate 10 is completely covered by the cladding member 30, the bottom end surface 221 of the lower positioning block 22 of each positioning column 20 does not protrude from the lower side wall 31, and the top end surface 214 of the top section 212 does not protrude from the lower side wall 31 either. The upper side wall 32 . And the plastic material forming the covering part 30 is embedded in the lower ring grooves 225 and the upper ring grooves 216 , which can increase the anchoring effect between the covering part 30 and the positioning posts 20 . The plastic material forming the covering part 30 is also used to pass through the through holes 15 and form the connecting parts 35, the lower side wall 31, the upper side wall 32, the outer ring wall 33, the shaft tube part 34 and the The connection part 35 is made of the plastic material forming the covering part 30 and is connected as a whole, which can ensure that the core board 10 is firmly combined with the covering part 30 after the upper cover 100 is manufactured.

Therefore, the present invention uses the cladding part 30 to directly embed the preformed core plate 10 and the positioning columns 20 in the injection process, and utilizes the core plate 10 to be made of metal, and the cladding part 30 and the core plate 10, can improve the overall structural strength of the upper cover 100, and through the setting of the positioning columns 20, it can improve the core plate 10 of the cladding part 30 in the injection process to produce better relative to the mold cavity. The positioning effect can improve the quality of the finished product of the upper cover 100 .

It is worth mentioning that each positioning post 20 of the above-mentioned embodiment of the present invention has the upper positioning block 21 and the lower positioning block 22 that can be disassembled relative to the upper positioning block 21, but if the positioning posts are pressed against each other Fixed to the core board 10, the positioning posts can also be made in one piece (not shown).

Furthermore, the new upper cover with a reinforced structure cooperates with the locks of the lock sets 3, and the metal rigid interlayer of the core plate 10 itself resists the internal pressure of the filter cartridge unit 1 to prevent the upper cover 100 from forming due to internal pressure. Afterwards, expansion and deformation will occur, which will eventually lead to rupture. It can indeed solve the problem that the existing upper cover that is directly formed by plastic injection or processed by engineering plastic CNC is prone to deformation and bursting of the simple plastic cover due to high pressure inside the filter tank.

To sum up, the upper cover with reinforced structure of the novel filter has a simple overall structure and is easy to manufacture and assemble, and can indeed achieve the purpose of the novel filter.

But the above-mentioned person is only the embodiment of the present invention, and should not limit the scope of implementation of the present invention with this, and all simple equivalent changes and modifications made according to the patent scope of the present application and the content of the patent specification are still within the scope of the present invention. Within the scope covered by this patent.
