Hydrodynamic force liquid mixer

The utility model relates to a hydrodynamic force liquid mixer. A directional support frame is installed in a shell via a gasket and a screw; the upper part of the directional support frame is provided with a slide push rod, the middle of the directional support frame is provided with a piston rod, and the lower part of the directional support frame is provided with a slide connecting rod; the slide push rod and the directional support frame are connected by a pull support; the pull support is connected with the slide connecting rod by a tension spring; the slide connecting rod is fixed with the shell by a seal ring and is fixed on a turnover frame via a clamping buckle B; the turnover frame is sequentially installed on the outer side of the bottom of the shell via an installation cap, a fastening ring and a positioning plate. The hydrodynamic force liquid mixer has the beneficial effects that the structure is simple, and the operation is convenient; an inner inserted mode is adopted for a piston connecting rod and is relatively firm; an inner slide mode is adopted for the repeated stretching motion of the tension spring, and the tension spring is good in stability; split design is adopted for the integral structure, the sealing effect is good, the use efficiency is high, water and a medicine liquid are mixed uniformly, and the service life of a part is prolonged.
