555 DC micro air pump is a small, high efficiency, low noise and long life gas pump. It adopts special design and precise processing technology, can quickly and smoothly pump air, hydrogen, nitrogen and other media out, widely used in air purification, aquaculture, ventilation, medical equipment, commercial electrical appliances, environmental protection equipment and other fields.

Compared to the traditional electric gas pump, it is small and light in weight. Its compact structure can be placed in a limited space, providing the possibility for the simplified design of the device. In the manufacturing process, the use of high-precision machines and high-tech materials, together with the full automatic production process, makes it have a very high performance stability and reliability. Using DC power supply, power consumption is very low, can save energy and reduce emissions, reduce energy consumption. At the same time, its noise control within an acceptable range, will not have negative effects on the surrounding environment and people's health. In terms of the internal structure, the 555 micro-air pump mainly includes the following components:

A. Motor: using high quality motor, convert electric energy into mechanical energy, drive the work of the air pump.

B. Control circuit: using the microprocessor intelligent control, to realize the automatic switch of the air pump, power display and other functions.

C. Air pump body: using the flywheel pressure type design, can be quickly and effectively inflated.

D. Air port: air port using a variety of specifications, can be compatible with a variety of inflatable equipment. It is also equipped with a safety check valve to avoid the damage caused by the gas backflow.

Firstly, in the medical field, it can be used to support the treatment of patients; secondly, in the tobacco industry, the equipment, military equipment, automobile air conditioners and other military equipment, in the military field, to bring more convenience to people's life.

It is mainly composed of motor, compressor, air valve and control circuit components. Its working principle is to use the motor to drive the compressor to work, the ambient air inhalation, and compressed into high pressure gas, through the air valve discharge to the position to be transmitted. Under the action of the control circuit, the air pump can start, stop, turn forward and reverse to realize the quantitative transmission of gas.

First, the input power supply transmits the current to the 555 microcontrol chip, and the transistors inside the control chip produce a high-frequency oscillating signal. This signal passes through the circuit board to the motor portion driving the air pump. Next, this high-frequency signal will be converted into a vibration inside the air pump, through which it draws the air into the inside of the air pump. At the same time, the piston inside the pump is driven to keep the air at high pressure at all times. When the pressure in the pump reaches a certain level, the pump will automatically close. In this process, the operation mainly depends on the high-frequency oscillatory signals. This signal can provide enough power to drive the air pump to achieve an efficient and stable compression effect. The following are the specific working steps:

Motor drive: the motor generates power by rotating the drive air pump. The speed and power of the motor directly affect the output capacity and efficiency of the air pump.

Gas inhalation and compression: During the rotation of the motor, the gas enters the air pump through the inlet and is then compressed in the compression chamber. The compression cavity is a sealed space, and through the operation of the motor, the gas is compressed in the cavity, increasing the pressure and density of the gas.

Gas discharge: When the gas pressure rises to a certain extent, the gas will be discharged through the outlet.

In addition, it also has a control system, which can monitor and control the running state of the air pump, including starting, stopping, adjusting pressure and so on. The control system usually consists of sensors, circuit boards, and controllers. The sensor can sense the parameters of the pressure and temperature of the gas and transmit this information to the circuit board. The circuit board controls the motor through the controller to realize the control of the air pump. In this way, micro-air pumps can meet the needs of different applications. In the control system, the 555 timer is a very important element that can produce a high precision output pulse signal and can perform multiple timing control according to the input signal. During the control process of the gas pump, we usually achieve different control effects by adjusting the parameters of the 555 timer. For example, we can control the working speed of the gas pump by changing the frequency of the input signal, thus achieving the control of the output gas flow of the gas pump. In addition to the 555 timer, there are many other components in the control system of the air pump, such as capacitance, resistance, transistors, etc. These elements are used to further modulate and amplify the output pulse signal of the 555 timer to control the output power of the air pump. In addition, there are some sensors and control chips and other auxiliary components, which can monitor and feedback the working state of the air pump in real time, so as to achieve a more accurate and stable control effect.
