Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an exhaust volume adjustable device for air compressors. Background Art

[0002] An air compressor is a device used to compress gas. The air valve of an air compressor is used to control the intake of air into the cylinder and the discharge of compressed air. The air valves of an air compressor are classified into two types according to their functions: intake valves and exhaust valves. They are opened by the gas pressure difference between the working chamber of the cylinder and the valve chamber, and rise due to the thrust of the air flow flowing through the valve during the intake and exhaust process; when the thrust is greater than the spring reaction force, the valve disc stays on the lift limiter; conversely, when the air flow thrust is less than the spring force, the valve disc closes downward.

[0003] Chinese patent No. 201922458337.8 discloses an exhaust valve for an air compressor, comprising a main body and an exhaust port shaft, wherein the exhaust port shaft is fixedly connected to one side of the top end of the main body; the main body comprises a connecting sleeve and a movable valve, the connecting sleeve is fixedly connected to the bottom end of the main body, and the movable valve is embedded in the top end of the main body; the exhaust port shaft comprises an air flow disk, an exhaust port and an adjusting disk, the air flow disk is fixedly connected to the top end of the exhaust port shaft, the exhaust port opening is arranged on one side of the air flow disk, and the adjusting disk is embedded around the middle of the exhaust port; the exhaust port comprises an engaging groove, an engaging groove mark and a limit block, the engaging groove opening is arranged in the middle around the exhaust port, the engaging groove mark is fixedly connected to one side of the middle of the engaging groove, and the limit block is fixedly connected to the middle of the engaging groove.

[0004] The above patent describes an adjustable exhaust volume device for an air compressor, which sets an airflow disk and an adjustment disk on the inner wall of the exhaust port, and uses the internal gas of the air compressor to impact the guide groove to use the rotating block to rotate and expand the adjustment dial, thereby adjusting the diameter of the exhaust port. This allows the device to exhaust more quickly when the air pressure is too high, thereby achieving the effect of adjusting the exhaust volume. Although the above method can meet the need for the device to exhaust quickly when the air pressure is too high, the repeated impact of high-pressure gas during the specific use of the device to expand the adjustment disk will cause the exhaust port to generate a large noise when the exhaust pressure is released, which is likely to cause noise pollution to the surrounding environment.

[0012] By adopting the above technical solution, the second connecting plate makes the connection between the device body and the movable valve tighter, and the movable valve can rotate on the surface of the second connecting plate, thereby adjusting the exhaust position of the exhaust port.

[0013] Furthermore, the connecting sleeve is bolted to the first connecting plate, the first connecting plate is bolted to the device body, the connecting sleeve is vertically fixed to the first connecting plate, and a touch panel is installed in the middle of the upper end of the fixing plate.

[0019] Furthermore, the exhaust port is connected to the mounting block with bolts, the exhaust port is connected to the silencer pipe with bolts, and the exhaust port is bonded to the silencer cotton.

[0020] By adopting the above technical solution, the gas inside the device is discharged through the exhaust port when in use, and the silencer cotton can effectively reduce the noise generated during exhaust.
