Abstract

The invention discloses a piezoelectric water-jet propulsion system and a toy boat equipped therewith. Defects of a conventional propulsion system and a mechanical transmission mechanism, such as complex structure, huge size and large weight, are improved to certain degree. The piezoelectric water-jet propulsion system comprises a battery chamber, an electronic chamber and piezoelectric water-jet propulsors. A battery pack for supplying power to the battery chamber is arranged in the battery chamber. The electronic chamber is internally provided with a driving circuit used for driving the piezoelectric water-jet propulsors. The driving circuit applies an electric field to piezoceramics in the piezoelectric water-jet propulsors such that high-frequency vibration is generated. A boat body is pushed forwards by converting electric energy into mechanical vibration applied to water. The toy boat is featured by being simple in structure, compact in size, low in weight and noise, stable in performance and smooth in operation.

Description

technical field [0001] The invention belongs to the field of underwater propulsion systems, and relates to a high-frequency electronic device, in particular to a piezoelectric water jet propulsion system and a toy boat equipped with the system. Background technique [0002] The water jet propulsion device is a new type of special power device. The typical structure of the water jet propulsion device is mainly composed of prime mover and transmission device, propulsion pump, pipeline system and so on. The propulsion water pump is the core component of the water jet propulsion device, and the axial flow pump and guide vane mixed flow pump in the vane pump are usually selected. The propulsion pump sucks in the water flow from the suction pipe at the bottom of the ship, sprays it out at high speed from the water spray pipe, obtains the reaction force of the water flow, and pushes the boat forward. The impeller of the propulsion pump of the water jet propulsion device works in a...
