Description of the invention: [Technical field of the invention] The present invention relates to an airtight structure improvement of a pressure cylinder, especially a pressure cylinder for preventing internal gas The airtight structure of pressure leakage. 1286489 [Prior Art] Reverse osmosis (REVERSE OSMOSIS, referred to as R0) is currently used in water treatment, and is generally affected by heavy women (4) - the county must be in the gambling for effective treatment of salt (such as mother, material hardness impurities), heavy metals Chemical chemistry is more than 95%. Especially for household drinking water, as well as biochemical medicines and electronic processes that focus on water quality, _ is favored, and this creation system points out the structure of the pressure cylinder in the reverse osmosis process associated with general household drinking water. - The process of reverse osmosis "The purified water (treated clean water) produced by the reverse osmosis membrane" is not necessarily consumed or used immediately, so the water is first stored in the -pressure cylinder first by the pressure cylinder and The faucet (such as the crane neck faucet) communicates, and when the faucet is turned on, there is a water pressure that forces the water to flow out. The general pressure cylinder is mainly formed by the upper cover and the lower cover, and the two are correspondingly combined: the inner part (four), and the i film is arranged along the inner edge of the upper cover, and the upper surface of the diaphragm and the inner edge of the upper cover form an entrance. The clean water chamber, and the pressure between the lower edge of the thief and the inner edge of the lower cover forms a pressure (4). The force ride refers to the pressure, which means that the county fills enough gas to form the air pressure (-about 7~1〇psi). When the clean water enters the dust cylinder, it will squeeze the diaphragm of the pressure cylinder (10). (4) The volume of the gas _ is reduced. Based on the principle that the magic force is inversely proportional to the volume, the force riding can exert the amount of water entering. The pressure to rebound to the tap is greater. Therefore, it can be seen that the maintenance of pressure is important for the grinding cylinder, and the prior art often causes the pressure leakage. 1. The combination of the upper and lower covers, and the diaphragm setting, often by the simple high circumference. 1286489 Wave or hot melt is a combination of surfaces, so the airtightness is not good and it is easy to leak the pressure inside the pressure cylinder very quickly after a period of time, so that the air must be filled frequently to pressurize, otherwise the water supply is insufficient to supply Use, and it is inconvenient. The disadvantages of high frequency or hot melt are that it is more labor-intensive, expensive, unstable, and cumbersome, so it is not ideal. 2. Moreover, the thermal fusion of the prior art tends to cause the melting to be inaccurate and the reason why the air is easily oozing out. 3. Further, the prior art was made of PP (Polypropylene), and the molecular structure of PP material is relatively sparse, which makes it easy for air molecules to pass through and cause vapor. 4. In addition, due to the above-mentioned technology and the lower cover, it is often carried out at its gap position. Usually, the gap range is only about 8-12 awake, so the gas barrier range is small. In other words, the air molecules are blocked. The path is short and the air molecules are easily oozing out of the gap. SUMMARY OF THE INVENTION The present invention improves the technical means used in the prior art, mainly in the improvement of the airtight structure of the pressure cylinder, mainly comprising an upper cover and a lower cover, which are combined with each other to form a combination, and along the inner edge of the upper cover a diaphragm is disposed, and the diaphragm is corresponding to the upper cover, and is formed into a bowl shape. The invention is particularly characterized in that: a bottom edge of the diaphragm forms a flange, and a hoop is arranged between the upper cover and the lower cover. Including the inner ring piece and the outer ring piece, the two 1286489 are connected by a spacer at the middle position to define an upper and lower insertion groove between the inner ring piece and the outer ring piece, and The flange of the diaphragm is allowed to be inserted into the upper insertion groove', and the upper cover and the lower cover are respectively placed into the upper and lower insertion grooves to form multiple and folded airtight functions.
