Cleaning device of tuning-fork densitometer

The invention discloses a cleaning device of a tuning-fork densitometer. The main points of the technical solution are that: the device includes a hollow cover body connected with a flange of the tuning-fork densitometer in a detachable manner to accommodate a tuning fork; the cover body includes a water injection chamber, a flow guiding plate which is disposed at a water outlet of the water injection chamber and guides water flow to a tuning-fork direction, and water injection pipes which are connected with the water injection chamber in a sliding manner to push water out of the water injection chamber from the water outlet; and heating wires drying the surface of the tuning fork are disposed in the cover body. The device has the advantage that when the tuning-fork densitometer is utilized to continuously detect density of different liquid, residual liquid on the surface of the tuning fork can be relatively thoroughly cleared after the tuning fork is removed from the previous liquid. 本发明公开了种音叉密度计的清洁装置，其技术方案要
