Fig. 1 and 2 show a pressurized air reservoir according to the present utility model comprising a thermoplastic canister 100 and a canister seal 110. The can seal 110 includes a tray 111, an inner ring piece 112, and an outer ring piece 113, the inner ring piece 112 and the outer ring piece 113 being connected to the tray 111 and protruding from the tray 111 in an axial direction Z of the tray 111, the outer ring piece 113 being located outside the inner ring piece 112 in a radial direction D of the tray 111, the inner ring piece 112, and the outer ring piece 113 being configured to form a receiving groove 115 that receives an end portion of the thermoplastic can 100.
Wherein the end of the thermoplastic canister 100 is hot melt joined to the can seal 110 and the outer annular tab 113 is configured with the outer sidewall of the can seal 110 to form a sealed cavity 130 for receiving the seal 120.
According to the pressure air storage tank, the thermoplastic tank 100 and the tank seal 110 are matched and installed, so that the pressure air storage tank has good sealing performance, is suitable for storing gas, and is low in production cost, light in weight and convenient to carry and install due to the arrangement of the thermoplastic tank 100.
As shown in fig. 1, the thermoplastic canister 100 is cylindrical before the pressurized air reservoir is installed, and the canister 110 may be made of a metal material, such as copper or steel. As can be seen from fig. 1, the tray 111, the inner ring piece 112 and the outer ring piece 113 of the can seal 110 are configured to form a receiving groove 115, and before the thermoplastic can 100 and the can seal 110 are thermally fused, the end of the thermoplastic can 100 is inserted into the receiving groove 115, so that after the thermoplastic can 100 and the can seal 110 are thermally fused, the sealing connection between the thermoplastic can 100 and the can seal 110 is achieved. Since the inner ring piece 112 and the outer ring piece 113 are respectively located at the inner side and the outer side of the thermoplastic can 100, the sealability between the can seal 110 and the thermoplastic can 100 is further enhanced.
Referring to fig. 2, after the end of the thermoplastic can 100 is hot-melt-connected with the can seal 110, the end of the thermoplastic can 100 is hot-melt-filled in the sealing cavity 130, thereby forming the outer rim 101, and the sealing cavity 130 is formed between the outer rim 101 and the outer ring piece 113 and the outer sidewall of the thermoplastic can 100.
Alternatively, the sealing cavity 130 is located outside the thermoplastic can 100 in the radial direction D, such that the sealing member 120 is mounted outside the thermoplastic can 100, facilitating the mounting of the sealing member 120.
Further, the outer rim 101 protrudes from the outer sidewall of the thermoplastic can 100 in the radial direction D and is connected to the inner sidewall of the outer ring piece 113, so that the thermoplastic can 100 and the outer ring piece 113 are hermetically connected, and the air tightness is good.
Further, the edge of the outer ring piece 113 far from the tray 111 is connected to the outer side wall of the thermoplastic can 100 by hot melting, so that a sealing cavity 130 is formed with the outer side edge 101 and the outer side wall of the thermoplastic can 100, so that the sealing cavity 130 for installing the sealing piece 120 is spaced from the end face of the thermoplastic can 100, a plurality of sealing structures are formed between the thermoplastic can 100 and the can seal 110, and the tightness between the thermoplastic can 100 and the can seal 110 is further improved.
Alternatively, the sealing cavity 130 is provided extending around the thermoplastic can 100 around the axis of the thermoplastic can 100, and the outer ring piece 113 is inclined to the outer side wall of the thermoplastic can 100 in a direction away from the tray 111 such that the sealing cavity 130 has a right triangle in cross section. When the end of the thermoplastic can 100 is inserted into the receiving groove 115, the outer ring piece 113 is forced to expand and contract and is pressed to the outer sidewall of the thermoplastic can 100, and then the sealing cavity 130 is formed by the subsequent hot melting treatment of the thermoplastic can 100. Alternatively, after the thermoplastic can 100 is assembled with the can seal 110, the thermoplastic can 100 may be heat-melted such that the outer sidewall of the end of the thermoplastic can 100 is configured to form the outer rim 101 and be connected to the outer ring piece 113, ensuring tightness between the thermoplastic can 100 and the can seal 110. And the thermoplastic can 100 and the outer ring 113 can be bonded and sealed by glue, so that the tightness between the thermoplastic can 100 and the can seal 110 is further ensured.
Optionally, the pressure air storage tank comprises at least one sealing member 120, the sealing member 120 is optionally a sealing ring and sleeved outside the thermoplastic can 100, and when the thermoplastic can 100 is in hot melt connection with the can seal 110, the sealing member 120 is respectively connected to the outer side wall of the thermoplastic can 100 and the inner side wall of the outer ring piece 113, so that the sealing performance of the pressure air storage tank is further enhanced.
Referring to fig. 2, optionally, at least one side wall of the inner ring piece 112 is inclined towards the outside along the axial direction Z of the disc 111, so that after the thermoplastic can 100 is inserted into the accommodating groove 115, the inner ring piece 112 is pressed against the inner side wall of the thermoplastic can 100, so that the inner ring piece 112 is in sealing connection with the inner side wall of the thermoplastic can 100, and then the sealing property between the thermoplastic can 100 and the can seal 110 can be further enhanced through the subsequent hot melting treatment of the thermoplastic can 100.
Referring to fig. 2, the pressurized air tank includes two cans 110, and the two cans 110 are respectively disposed at both ends of the thermoplastic can 100.
Alternatively, the pressurized air reservoir may include only one canister 110, and the thermoplastic canister 100 may alternatively be open at one end, with the canister 110 being disposed at the open end of the thermoplastic canister 100.
Further, at least one of the canister 110 is provided with a pressure injection and relief valve 114, so that the air pressure in the pressure air storage tank can be prevented from being too high, and the air injection into the pressure air storage tank is facilitated.
Alternatively, the can 110 is constructed as a metal member and the thermoplastic can 100 is constructed as a fiber reinforced thermoplastic resin member, thereby facilitating assembly and hot melt connection between the thermoplastic can 100 and the can 110, as well as disassembly and maintenance.
According to the pressure air storage tank, the tank body volume can be flexibly customized by cutting thermoplastic pipes with different lengths to form the thermoplastic tank barrel 100, and the thermoplastic pipes can be continuously extruded for production, so that the production efficiency is improved compared with the traditional method that each thermoplastic tank barrel 100 is independently injection molded.
In addition, according to the pressure air storage tank of the present utility model, as the air pressure in the bottle increases (within a certain range), the thermoplastic canister 100 and the canister seal 110 (particularly the outer ring 113) are more tightly closed, so that the sealing performance is better
