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 1

[0033] Such as figure 1 As shown, an electric water pump of the present invention includes a motor 10, a gear set 20, a transmission mechanism 30, a piston mechanism and a stroke changing mechanism. The output shaft of the motor 10 is connected to the transmission mechanism 30 through the gear set 20, and the transmission mechanism 30 is connected to For the piston mechanism (in practical application, the piston mechanism adopts a single-piston structure), the piston mechanism includes a piston cylinder 41, a piston body 42 is arranged in the piston cylinder 41, the piston body 42 is connected to the transmission mechanism 30 through the piston rod 43, and the transmission mechanism 30 passes The piston rod 43 drives the piston body 42 to move up and down. The piston cylinder 42 is provided with a water outlet 44 and a water inlet 45. The water outlet 44 is provided with a water outlet valve 46, and the water inlet is provided with a water inlet valve 47. Specifically, the pist...

Embodiment 2

[0045] Such as Figure 9 As shown, in this embodiment, the water flow buffer chamber 51 is arranged in an I-shaped structure cooperating with the movable components, and the number of baffles 57 is reduced. During work, the upper movable plate 54 is pushed downward by the water flow driven by the piston body 42, and the upper movable plate 54 can close the water flow hole 571 after contacting the water flow hole 571 to realize the closure of the drainage bypass. After the energy is released, the water flow The drainage bypass formed by the buffer cavity 51 loses resistance, the lower movable plate 55 is pushed upward by the elastic force of the spring 52, and after the upper movable plate 54 is separated from the baffle plate 57, the water flow hole 570 can be opened to start the drainage bypass. The function of the water flow hole 571 is to let water flow through. It should be noted that the diameter of the water flow hole 571 must be smaller than the area of ​​the upper mov...

Embodiment 3

[0048] Such as Figure 10 As shown, in this embodiment, a side hole 58 is opened on the side wall of the piston cylinder 41, and a simple drainage channel is communicated through the side hole 58, thereby reducing movable components, which mainly pass through the side hole 58 of the piston body 42. The opening and closing of the drainage channel is realized. When the motor 10 is working, the gear set 20 and the transmission mechanism 30 push the piston body 42 to move upwards. At this time, the piston mechanism is in the drainage stroke. Since the drainage bypass formed by the drainage channel has little resistance to the water flow, (that is, the water flow is easy to flow beside the drainage. flow in the middle of the road), and the resistance of the water outlet 44 to the water flow is much greater than the resistance of the drainage channel to the water flow, the water inside the piston cylinder 41 is pushed to discharge through a path without resistance, that is, it is di...

Abstract

The invention relates to the technical field of liquid pumps and water gun structures, in particular to an electric water pump and a water gun structure. The electric water pump comprises a motor, a gear set, a transmission mechanism, a piston mechanism and a stroke changing mechanism. The motor is connected to the transmission mechanism through the gear set. The transmission mechanism is connected to the piston mechanism. The piston mechanism comprises a piston cylinder. A piston body is arranged in the piston cylinder and is connected to the transmission mechanism through a piston rod. The transmission mechanism drives the piston body to move up and down through the piston rod. The piston cylinder is provided with a water outlet and a water inlet. The water outlet and the water inlet areeach provided with a valve. The stroke changing mechanism comprises a water draining bypass and a control mechanism. The water draining bypass communicates with the piston cylinder. The control mechanism controls opening and closing of the water draining bypass. The water draining bypass is added to the piston mechanism of the electric water pump, thus the electric water pump can accumulate energy before a piston enters an effective water draining stroke, the accumulated energy is released when the piston enters the effective water draining stroke, and 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. 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 pump does not simply discharg...
