According to the electric water pump, the transmission mechanism of the electric water pump is provided with the peach-shapedcam, and the ring part of the peach-shaped cam is driven by the transmission mechanism to rotate for energy storage, and the output water pressure of the electric water pump is increased.

Description

technical field [0001] The invention relates to the technical field of liquid pumps, in particular to an electric water pump and a water gun structure with an improved transmission mechanism. Background technique [0002] An electric water pump generally includes a motor, a gear set, a transmission mechanism and a piston assembly, wherein the motor is connected to the transmission mechanism through the gear set, and the transmission mechanism is connected to the piston assembly, so that the motor drives the piston assembly to move the piston. During the working process of the electric water pump, its piston assembly includes a water suction stroke and a discharge stroke. Wherein, the water suction stroke is the distance moved by the piston during the process of sucking the external water into the piston assembly; the drainage stroke is the distance moved by the piston during the process of discharging the water inside the piston assembly. In practical applications, the elec...

Problems solved by technology

[0003] In the existing technology, the only way to increase the output water pressure of the electric water pump is to increase the power of the motor of the electric water pump. The direct way is to use a high-power motor, and the high-power motor has high price, large volume, and high requirements for power supply equipment. characteristics, resulting in a great increase in the cost, volume and quality of electric water pumps, which directly limits the application range of electric water pumps
