[0022] Preferred embodiment.

[0023] This embodiment provides a filter-type pressure water storage tank, including a tank body, a rubber diaphragm, and a fixing ring 250. The rubber diaphragm includes an integrally formed first main body 210, a first connecting part 220, and a first support part 230. The first connecting part 220 extends obliquely upward along the outer side of the first main body 210, and the first support part 230 extends vertically downward along the outer side of the first connecting part 220. The lower end of the first support part 230 is provided with a first mounting part 231 that protrudes inward. The inner side of the tank is provided with a first positioning protrusion, the curvature of which is the same as the outer curvature of the first mounting part 231. The fixing ring 250 is provided with a first positioning groove that is recessed inward, the curvature of which is the same as the inner curvature of the first mounting part 231.

[0024] The upper end of the barrel is provided with a water inlet pipe 162, and the upper end of the barrel is provided with a first filter barrel 130. The lower end of the first filter barrel 130 is provided with a first connection port 131, which is connected to the barrel. The first filter barrel 130 is provided with a first filter element 132. The upper end of the first filter barrel 130 is provided with a first outlet. The first outlet is provided with a first valve body 150. The upper end of the first valve body 150 is provided with a first valve cap 151, which is threadedly connected to the first valve body 150. The first valve body 150 is provided with a first piston 153, which is matched with the first connection port 131.

[0025] The upper end of the barrel is provided with a first water inlet cylinder 160 and a first connecting ring 170. The first water inlet cylinder 160 is threadedly connected to the first connecting ring 170. The first connecting ring 170 is provided with a first limiting ring 171. The first limiting ring 171 and the first connecting ring 170 form a first limiting groove 172. The lower end of the first water inlet cylinder 160 is provided with a second limiting ring 161. The second limiting ring 161 matches the first limiting groove 172. The upper end of the first water inlet cylinder 160 is provided with a first water inlet pipe 162. The first water inlet cylinder 160 is provided with a plurality of first filter rods 180. The first filter rods 180 are disposed on the barrel.

[0026] Because of their similar curvature, the fixing ring 250 can fix the rubber diaphragm to the first positioning protrusion. Furthermore, the self-limiting effect formed by the bulges of the fixing ring 250 and the first positioning protrusion ensures the stable use of the rubber diaphragm. Therefore, the rubber diaphragm can divide the internal space of the tank into a water chamber and a pressure chamber, thus ensuring the usability of the pressure tank. In addition, during water intake, the water enters the first water inlet cylinder through the first water inlet pipe, and then undergoes fine filtration by the first filter rod, trapping impurities within the first water inlet cylinder, achieving water filtration. During water outlet, the water enters the first filter tank through the first connection port, undergoes further filtration by the first filter element, and finally exits through the first valve cap, achieving water filtration. Therefore, through two filtration processes—intake and outlet—drinking water safety can be guaranteed.

[0027] Furthermore, the first main body 210 and the first support 230 are both connected to the first connecting part 220 by an arc transition. The upper end of the first main body 210 is provided with a first reinforcing ring 211, and the lower end of the first main body 210 is provided with a second reinforcing ring 212. The lower end of the second reinforcing ring 212 is provided with a first extension edge 213 extending inward to the inner side of the second reinforcing ring 212. The first extension edge 213, the second reinforcing ring 212 and the first main body 210 surround a first slot 214. The first slot 214 is provided with a first reinforcing piece 215, which is an annular convex shape.

[0028] Furthermore, the barrel body includes a first barrel body 110 and a second barrel body 120, the first barrel body 110 is welded to the upper end of the second barrel body 120, and the first positioning protrusion is disposed at the lower end of the first barrel body 110.

[0029] Furthermore, a first locking groove 140 is provided between the first barrel body 110 and the second barrel body 120, and a first locking part 240 is provided extending outward from the lower end of the first support part 230, and the first locking part 240 matches the first locking groove 140.

[0030] Furthermore, the upper end of the first piston 153 is provided with a first guide shaft, and the lower end of the first valve cap 151 is provided with a first limiting tube 152. The first guide shaft matches the first limiting tube 152, and a first spring 155 is sleeved on the first limiting tube 152. The first spring 155 corresponds between the first valve cap 151 and the first piston 153.
