Double-vibrator low-noise compressor

Abstract

The invention relates to a double-vibrator low-noise compressor. A lower shell, a middle shell and an upper shell are included. The lower shell is connected with the middle shell. The middle shell isconnected with the upper shell. The middle shell comprises two vibrator units. Each vibrator unit comprises a first valve base, a first valve base cover plate, a vibrator, a second valve base cover plate and a second valve base, wherein the first valve base is connected with the first valve base cover plate, the first valve base cover plate is connected with the vibrator, the vibrator is connectedwith the second valve base cover plate, and the second valve base cover plate is connected with the second valve base. The two vibrator units are symmetrically distributed. Each first valve base cover plate comprises a valve base front cover, an outer center strengthening sheet, an inner center strengthening sheet and a flat film. The design of the double vibrator units is adopted in the double-vibrator low-noise compressor, dynamic balance during vibrator unit work is achieved, and the vibration noise during compressor work is lowered.

Description

technical field [0001] The invention relates to a double vibrator low-noise compressor. Background technique [0002] The compressor is a component widely used in medical air pumps. Most of the linear oscillating compressors on the market today are designed with a single vibrator. When the single vibrator is working, it uses the vibrator to compress the basin-shaped diaphragm to achieve Inflatable purpose. However, the single vibrator can never offset the inertia of the vibrator when it is working. When the vibrator moves to the maximum distance from the far point, it needs to move in the opposite direction quickly, which causes the compressor to make a lot of noise when it is working. When it is installed in a medical air pump and used in a ward Sometimes it will produce a lot of noise, which will seriously affect the user's rest and cause customer complaints. [0003] In addition, the air inlet and air outlet of existing compressors have the same caliber, but there is on...

Problems solved by technology

However, the single vibrator cannot offset the inertia of the vibrator when it is working. When the vibrator moves to the maximum distance from the far point, it needs to move in the opposite direction quickly, which causes the compressor to make a lot of noise when it is working. When it is installed in a medical air pump and used in a ward It will generate a lot of noise, which will seriously affect the user's rest and cause customer complaints

[0003] In addition, the air inlet and air outlet of existing compressors have the same caliber, but there is only one air inlet and two air outlets. If the air volume is the same, the airflow velocity at the inlet is twice that of the outlet. , the airflow speed is too high, the airflow noise generated when flowing through the air hole is greater, the impact on the intake valve is also greater, the energy of the flapping of the valve plate is also greater, and the noise is greater
