Waist Massager 12V DC Mini Electronic Air Pumps

Micro diaphragm air pump is a small and lightweight air pump commonly used in medical devices, massagers, and other equipment. In knee massagers, the micro diaphragm air pump can provide airflow, helping the massager produce a massage effect.

Knee massagers usually use airbag massage to achieve massage function through inflation and deflation. The mini air pump can provide stable airflow, ensuring the stability and durability of the massage effect of the massager.

What are the advantages of micro diaphragm air pumps in knee massagers？

2. Small size and light weight: Due to the compact design of the micro diaphragm air pump, it can be easily integrated into the knee massager without significantly increasing the size or weight of the entire device. This allows the knee massager to maintain its functionality while also maintaining its portability, making it easy for users to carry and use when needed.

3. Low noise: The operating noise of micro diaphragm air pumps is usually very low, which ensures that the knee massager does not interfere with the user's rest or work during use. Especially in home environments, low noise characteristics are particularly important to ensure that users can maintain a peaceful environment while using the massager.

4. Low energy consumption: Micro diaphragm air pumps usually have lower energy consumption, which means knee massagers can maintain good performance even after long-term use, and do not require frequent battery replacement or charging.

5. Multiple massage methods: By using a micro diaphragm air pump and knee massager, various massage methods can be achieved, such as continuous massage, pulse massage, etc. These different massage methods can be adjusted according to the user's personal preferences and needs to provide the best massage experience.

6. Improve blood circulation and comfort: The massage function provided by the electric air pump can effectively improve blood circulation around the knee joint, relieve knee pain and stiffness. This can not only improve user comfort, but also help prevent or alleviate some knee joint related diseases.

Air pump dimension

How does the micro diaphragm air pump work in a knee massager？

1. Motor drive: The micro diaphragm air pump is equipped with a small motor inside, which starts to rotate when it starts.

2. Diaphragm motion: The rotation of the motor is converted into the reciprocating motion of the diaphragm inside the pump through a mechanical device. This type of diaphragm is usually a thin film made of elastic material that can move back and forth within the internal space of the pump.

3. Air compression and stretching: When the diaphragm moves forward, it compresses the air inside the pump chamber, forming positive pressure; When the diaphragm moves backwards, the air inside the pump chamber is stretched, forming negative pressure. This alternating generation of positive and negative pressure forms an airflow.

4. Air flow generation: At the suction port, when negative pressure is formed in the pump chamber, air will be sucked into the pump chamber due to the presence of external atmospheric pressure. When positive pressure is formed in the pump chamber, air will be discharged from the exhaust port, resulting in a stable airflow.

5. Massage effect: This stable airflow is directed into the airbag of the knee massager, which expands and contracts to massage the knee area. Different massage modes and intensities can be achieved by adjusting the airflow flow and pressure.

6. Control and adjustment: Knee massagers are usually equipped with a control system, and users can adjust the intensity, time, and mode of massage parameters through the control panel or remote control to meet personal comfort and needs.

Technical Specification

How can the small diaphragm air pump adjust and control the intensity and duration of massage in a knee massager?

1. Massage intensity adjustment:

·Air flow control: Micro diaphragm air pumps are usually equipped with air flow control devices, such as regulating valves or frequency converters. By adjusting these devices, the output airflow of the air pump can be controlled, thereby adjusting the intensity of the massage. Increasing the airflow can enhance the massage effect, while reducing the airflow will weaken the massage intensity.

·Pressure sensors and feedback: Some advanced knee massagers may be equipped with pressure sensors for real-time monitoring of the air pressure inside the airbag. Through the feedback mechanism between sensors and control systems, the massage intensity can be precisely controlled to ensure that the massage intensity always remains within the user's expected range.

2. Massage time control:

Timer: The control system of knee massagers usually has a built-in timer function. Users can set the massage time through the control panel or remote control, ranging from a few minutes to several tens of minutes. Once the set time is reached, the massager will automatically stop working to avoid excessive massage or forgetting to turn off the device.

·Multi mode selection: In addition to basic massage time settings, some knee massagers also offer multiple massage modes, such as continuous massage, intermittent massage, etc.

Users can choose different massage modes according to their own needs, and set the duration and interval of each mode through the control system to achieve the best massage effect.

Performance test drawing

How to evaluate the sealing performance of micro diaphragm air pumps?

The sealing performance of micro diaphragm air pumps can be evaluated through the following steps:

1. Prepare testing equipment: It is necessary to prepare a micro diaphragm air pump, a vacuum gauge, a pressure gauge, a gas flow meter, and corresponding connecting pipelines and valves.

2. Connect testing equipment: Connect the small dc air pump, vacuum gauge, pressure gauge, and gas flow meter to ensure good sealing at the connection and avoid gas leakage.

3. Preparation before testing: Turn on the mini electric air pump and let it run for a period of time to ensure stable internal temperature and eliminate possible impurities or gases inside the pump.

4. Conduct testing: First, close all valves and record the initial readings of the vacuum gauge and pressure gauge. Then, open the outlet valve of the micro diaphragm air pump and let it run for a period of time. Record the reading of the gas flow meter and the changes in the vacuum gauge and pressure gauge. Next, close the outlet valve, observe the changes in the vacuum gauge and pressure gauge, and record the rate of gas leakage.

5. Analyze test results: Based on the data recorded during the testing process, analyze the sealing performance of the micro diaphragm air pump. If the gas leakage rate is small, it indicates good sealing performance; If the gas leakage rate is high, further inspection or maintenance of the air pump is required.
