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

Embodiment 2

[0035] Such as Figure 7 As shown, the pressure structure includes a peach-shaped cam 80 arranged on the transmission structure 30. The peach-shaped cam 80 is driven to rotate by the transmission shaft of the transmission structure 30. The initial state is that the ring part of the peach-shaped cam 80 corresponds to the piston rod 43. Setting, driven by the transmission mechanism 30, the peach-shaped cam 80 can rotate 270 degrees at an angle equivalent to energy storage. When the convex part of the peach-shaped cam 80 is set corresponding to the piston rod 43, the convex part will suddenly lift the piston rod 43 , the piston rod 43 drives the piston body 42 to move upward at a high speed, so as to quickly apply pressure to the water in the piston cylinder 41, thereby obtaining an instantaneous high-pressure water flow, increasing the output water pressure of the electric water pump, and the peach-shaped cam 80 continues to rotate until the stored energy is released. The ring p...

Abstract

The invention relates to the technical field of liquid pumps, in particular to an electric water pump with the pressure structure and a water gun structure. The electric water pump comprises a motor,a gear set, a transmission mechanism, a piston mechanism and the pressure structure. An output shaft of the motor is connected with the transmission mechanism through the gear set. The transmission mechanism drives the piston mechanism to output high-pressure water flow through the pressure structure. The piston mechanism comprises a piston cylinder. The piston cylinder is provided with a water outlet and a water inlet. A water outlet valve is arranged on the water outlet. A water inlet valve is arranged on the water inlet. A piston body is arranged in the piston cylinder. The piston body is connected with a piston rod. The transmission mechanism drives the piston rod to drive the piston body to move upwards to output high-pressure water flow through the pressure structure. A resetting mechanism is arranged on the piston body. Through the structure arrangement, the transmission mechanism drives the piston rod to drive the piston body to move upwards to output the high-pressure water flow through the pressure structure, and the output water pressure of the electric water pump is improved accordingly.

Description

technical field [0001] The invention relates to the technical field of liquid pumps, in particular to an electric water pump with a pressure structure and a water gun structure. 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 electric water pum...
