DQB440-A is a high-flow Mini Air Pump with a flow range of 8-10L, which is very suitable for 6-point massage and 8-point pneumatic massage. This miniature air pump has the advantages of small size, light weight, easy installation, high efficiency and long life. It is usually used in various massage equipment to provide stable air pressure and flow to achieve a comfortable massage effect. Pay attention to care and maintenance when using it to ensure its normal operation and extend its service life.
What is the eccentric wheel in the micro Dc Air Pump for?
1. Connect the motor shaft and connecting rod assembly: the eccentric is used to transmit the rotational motion of the motor shaft to the connecting rod assembly.
2. Control the vibration of the connecting rod assembly: By driving the rotation of the eccentric wheel by the motor, the connecting rod assembly can be driven to vibrate.
3. Drive the diaphragm to reciprocate: the connecting rod assembly is connected to the diaphragm, and the vibration of the eccentric will cause the diaphragm to reciprocate.
4. Control the valve plate for the air inlet and outlet: The reciprocating motion of the diaphragm cooperates with the valve plate for the air inlet and outlet to complete the process of air extraction and deflation.
Through the cooperation of the eccentric wheel and the connecting rod assembly, the micro air pump can realize the function of pumping fluid.
How does the eccentric in the Small Diaphragm Air Pump control the vibration of the connecting rod assembly?
The eccentric wheel in the micro air pump controls the vibration of the connecting rod assembly in the following ways:
1. Rotation of the eccentric: The rotation of the eccentric is driven by the motor. When the motor shaft rotates, the eccentric will also rotate.
2. Connection of the connecting rod assembly: One end of the connecting rod assembly is connected to the eccentric, usually through elastic elements such as sliding bearings or springs.
3. Vibration transmission: When the eccentric rotates, the centrifugal force generated by it acts on the connecting rod assembly, causing the connecting rod assembly to vibrate. Due to the connection stiffness between the connecting rod assembly and the eccentric, the vibration frequency and amplitude of the connecting rod assembly will be limited.
4. Reciprocating motion of the diaphragm: The vibration of the connecting rod assembly will cause the diaphragm to reciprocate at the same frequency. The diaphragm is a closed elastic element whose shape and size are designed according to the design requirements of the Small DC Air Pump.
5. Valve opening and closing: The reciprocating movement of the diaphragm cooperates with the valve opening of the air inlet and outlet to complete the process of pumping and deflating. When the diaphragm moves toward the air inlet, the air inlet opens and air is sucked into the pump; when the diaphragm moves toward the exhaust port, the exhaust port opens and the air is discharged out of the pump.

How does the eccentric speed of the car massage mini electric air pump affect the massage effect?
The eccentric speed of the car massage portable electric air pump will affect the massage effect, which is specifically reflected in the following aspects:
1. Massage intensity: The higher the eccentric wheel speed, the greater the air pressure generated, and the massage intensity will increase accordingly. According to the individual's stress level, the massage intensity can be adjusted by adjusting the rotation speed of the eccentric wheel.
2. Massage frequency: The rotation speed of the eccentric wheel also directly determines the frequency of massage. Massage frequency refers to the speed at which the massage head repeatedly inflates and deflates. The higher the massage frequency, the faster the massage effect, and vice versa. By adjusting the rotation speed of the eccentric wheel, the frequency of massage can be changed to adapt to different massage needs.
3. Massage area: Due to the rotation of the eccentric wheel, the massage head will produce a massage effect on the skin with a certain radius. The higher the rotational speed, the faster the massage head moves and the wider the area it covers. This can expand the massage range and reduce fatigue and tension in certain parts.
4. Comfort: The adjustment of the eccentric wheel speed will also affect the comfort of the massage. For sensitive areas or areas that require gentle massage, the eccentric wheel speed can be reduced to reduce irritation and discomfort. For areas that require stronger massage intensity, the rotation speed can be appropriately increased to enhance the massage effect.
How does the eccentric in the Electric Air Pump adjust the vibration frequency of the connecting rod assembly?
The eccentric in the electric air compressor pump can adjust the vibration frequency of the connecting rod assembly by changing its rotation speed. When the eccentric rotates faster, the centrifugal force it generates increases, causing the vibration frequency of the connecting rod assembly to increase. On the contrary, when the eccentric rotation speed slows down, the centrifugal force decreases and the vibration frequency of the connecting rod assembly also decreases. Therefore, by adjusting the speed of the micro air pump motor, the rotation speed of the eccentric can be changed, thereby adjusting the vibration frequency of the connecting rod assembly. It should be noted that adjusting the vibration frequency will also change other parameters such as the flow rate and pressure of the micro air pump, so comprehensive considerations need to be made based on specific needs in practical applications.
