Vertical air pump filter

Abstract

The invention discloses a vertical air pump filter. The vertical air pump filter comprises an outer shell, wherein a positioning threaded ring is arranged at the bottom of one side of the outer shell; the side surface of the positioning threaded ring is in threaded connection with a positioning plate; an air inlet hole is formed in the surface of one side of the positioning plate; the surface of the other side of the positioning plate is fixedly connected with a filter cartridge; the surface of the other end of the filter cartridge is fixedly connected with a pressing plate; a cover plate is mounted at an opening in one end of the outer shell in a threaded manner; a pressing groove is formed in the surface of one side of the cover plate; the side surface of the pressing groove is connected to the side surface of the pressing plate in a pressing manner; a sealing ring is arranged on the surface of one side of the pressing groove; the surface of the sealing ring is connected to the end surface of the pressing plate in a jacking manner; a right-angle pressure relief hole is formed in the surface of one side of the pressing groove; and one end of the right-angle pressure relief hole is positioned on the surface of the other side of the cover plate. Therefore, the convenience and the stability of use can be greatly improved, and the safety and the high efficiency of mounting and maintenance are ensured.

Description

technical field [0001] The invention relates to the field of filters, more specifically, to a vertical air pump filter. Background technique [0002] During the use of the vertical air pump, in order to ensure stable operation and gas safety, it is necessary to install a filter to filter the incoming gas to avoid interference from impurities blocking the pipeline. [0003] However, most of the existing filter structures directly insert and position the filter cartridge to one end of the gas tank. Although it can be filtered, it needs to be maintained and disassembled, which is easily affected by the internal air pressure, causing the cover to be too tightly connected and inconvenient to disassemble. The convenience is poor, and at the same time, the internal high-pressure gas cannot be relieved and discharged, and there is no effective reminder. It is easy to cause airflow impact and injury during disassembly, and the safety is insufficient, which needs to be improved. Con...

[0003] However, most of the existing filter structures directly insert and position the filter cartridge to one end of the gas tank. Although it can be filtered, it needs to be maintained and disassembled, which is easily affected by the internal air pressure, causing the cover to be too tightly connected and inconvenient to disassemble. The convenience is poor, and at the same time, the internal high-pressure gas cannot be relieved and discharged, and it cannot be effectively prompted. It is easy to cause airflow impact and injury during disassembly. The safety is insufficient and needs to be improved.
