Description

Technical Field

[0001] The present invention relates to the technical field of air pumps, and in particular to a pump-valve integrated air pump. Background Art

[0002] A micro air pump is a small gas compression device, which is widely used in various occasions that require small gas power. It has the advantages of small size, light weight, low power consumption, low noise and DC power supply adaptability to various power supply modes. It is widely used in medical equipment, household appliances, laboratory instruments, automobiles and industrial automation. However, the selection of a micro air pump needs to consider its flow rate, pressure, power consumption, noise and other parameters to ensure that it can meet the needs of specific applications. However, the existing micro air pumps still have some shortcomings in practical applications, which limit their performance improvement and wide application.

[0003] Among them, 1. Vibration and noise: When the existing micro air pump needs to provide high-pressure and high-flow air, due to the small volume of its air bag or air membrane, it is necessary to drive the motor to rotate at a higher speed. Usually the air bag or air membrane is driven by a motor and an eccentric mechanism, which will cause more obvious vibration and increased noise when the motor rotates at a high speed. At the same time, since there is no valve air collection buffer, the high-speed airflow generated will also make sound, which will mix with the vibration noise to form a greater noise.

[0004] 2. Volume and weight: Although the existing micro air pumps are much smaller than traditional air pumps, the volume and weight of the overall system are still large due to the separate design of the pump and valve, which is not ideal, especially in applications that require high integration and lightness.

[0005] 3. Energy loss: In traditional designs, pumps and valves are connected by pipes, which inevitably lead to energy loss and reduce the efficiency of the system. This energy loss is particularly obvious in applications with long-term operation or high precision requirements.

[0006] 4. Reliability issues: Due to the presence of air pipes and connectors, existing micro air pump systems are prone to leakage and loose connectors during long-term operation. In addition, air pipes and connectors take up more volume, affecting the reliability and stability of the system.

[0007] In order to overcome the above shortcomings of existing micro air pumps, the pump-valve integrated micro air pump came into being. The pump-valve integrated design integrates the pump and valve in a compact device, aiming to improve the overall performance and reliability of the system, simplify the installation and maintenance process, reduce vibration and noise during operation, and reduce energy loss and system volume.

[0008] In summary, it is found that the prior art has at least the following technical problems:

[0009] The existing micro air pump is separately arranged from the control valve, which has the problems of being noisy and bulky, and being difficult to improve the overall performance and reliability. Summary of the invention

[0028] (4) High reliability: Due to the reduction of connectors and pipelines in traditional air pumps, the leakage points and failure points of the pump-valve integrated air pump are greatly reduced. This design greatly improves the reliability and stability of the system, especially for applications that require long-term stable operation.

[0029] (5) Effective gas control: The design of the buffer chamber and the gas collecting plate allows the airflow to be effectively buffered and balanced before entering the gas collecting chamber, avoiding airflow pulsation, reducing the noise generated by high-speed airflow turbulence, and increasing the stability of the airflow output to the next level; the setting of the one-way valve ensures the one-way flow of gas and automatically controls the opening and closing of the airflow according to the pressure, ensuring the stability and safety of gas output.
