[0016] Compared with the prior art, the vibration mixing mechanism for the magnetic particle mixing equipment has the following advantages:

This not only accelerates particle collision, friction, and dispersion but also allows the mixture to vibrate in multiple directions within the container, avoiding the "dead zones" phenomenon found in traditional mixing. The vibration mechanism can apply force to the mixture from multiple directions, enhancing particle collision and friction, and helping to improve mixing efficiency, making it particularly suitable for mixing high-viscosity liquids or particulate matter. The rubber blocks within the hammer structure provide cushioning, reducing the impact on the equipment during vibration, while also allowing for better control of the vibration amplitude, avoiding excessive pressure on the mixing container and materials, especially suitable for easily damaged particles (such as cells, sensitive materials, etc.). Through continuous vibration, the vibration mechanism effectively reduces sediment accumulation, enhances material suspension, and avoids the settling problems common in traditional mixing processes.

[0018] 2. The elastic support device effectively absorbs the impact force transmitted to the equipment by the vibration mechanism, reducing direct impact between mechanical parts. It effectively reduces wear on internal components, preventing damage caused by prolonged strong vibration and extending the equipment's service life. Through elastic support, the equipment can operate more smoothly during vibration, reducing the pressure of uneven vibration on the mechanical structure and ensuring the stability of the equipment during long-term use. The elastic support device helps the vibration system maintain balance, playing a stabilizing role during vibration and preventing excessive or uneven vibration. It ensures the accuracy and stability of vibration frequency and amplitude, making the mixing process more uniform and efficient. The elastic support smooths the vibration output, avoiding uneven material mixing or container damage that may be caused by uneven vibration or excessive impact force. Attached Figure Description
