AI Technical Summary
Existing simulated hydraulic press devices require complex electrical control components, consume a lot of energy, are expensive, and are not easy to move, resulting in low user willingness to purchase.
A hydraulic press science toy was designed, which uses a base with a built-in water tank, and connects the hydraulic top cover and support plate through multiple columns. It uses auxiliary hydraulic cylinders and main hydraulic cylinders to achieve the force amplification effect, uses a needle-free injector as the hydraulic cylinder, eliminates electronic control devices, and achieves force amplification through liquid pressure transmission.
It has achieved a compact and aesthetically pleasing hydraulic experimental device with strong dynamic interest and operability. It is suitable for home science education and toy assembly, providing a good user experience and does not rely on electronic control components.
