[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0020] like Figure 1 , Figure 2 , Figure 3As shown, this dual-inlet high-efficiency water pump includes a pump body 1, which comprises two cylinders 2, two piston reciprocating mechanisms 3, and a drive motor 4. The motor shafts of the drive motor 4 extend from both ends and are connected to the piston reciprocating mechanisms 3 located on both sides of the drive motor 4. Each of the two cylinders 2 is provided with an inlet pipe 5 for water intake. A water passage pipe 6 is provided between the two cylinders 2 for water flow. The water passage pipe 6 is provided with an outlet section 7 for water discharge. The outlet section 7 is provided with several outlet pipes 8. The piston reciprocating mechanisms 3 include… The device includes a mounting bracket 9, a connecting shaft 10, a rotating wheel 11, a piston part 12, a piston rod 13, and a drive gear 14. The mounting bracket 9 is fixedly mounted on the drive motor 4 by fixing bolts. The piston part 12 is located inside the cylinder body 2. The drive gear 14 is connected to the rotating wheel 11 by the connecting shaft 10 and moves synchronously. The piston rod 13 is fixedly mounted on the rotating wheel 11 and moves the piston part 12 inside the cylinder body 2 as the rotating wheel 11 rotates. Check valve components 15 for checking backflow are provided inside the water outlet 7 and at each water outlet pipe 8 and at each of the two water inlet pipes 5.
[0021] To elaborate further on the working principle of the water pump, when it starts working, the drive motor 4 drives the connecting gear 22 to rotate, which in turn drives the drive gear 14 to rotate. The drive gear 14 drives the piston rod 13 to move, causing the piston part 12 set in the cylinder 2 to move backward, creating negative pressure inside. Liquid enters the cylinder 2 from the water inlet pipe 5. The piston rod 13 continues to move, driving the piston part 12 in the cylinder 2 to move forward, so that the liquid enters the water outlet 7 through the water passage pipe 6, and flows out from the various water outlet pipes 8 on the water outlet 7.
[0022] To elaborate further, the check valve assembly 15 consists of a check valve 16 and a return spring 17. A fixing part 18 is provided inside the water outlet pipe 8. The fixing part 18 has several water outlet holes 19 for water outlet. A baffle plate 20 for check valve is provided at the front end of the check valve 16. A connecting part 21 is provided at the rear end of the check valve 16. The return spring 17 is located between the connecting part 21 and the fixing part 18.
[0023] To elaborate further, the back end of the check valve component 16 in the check valve assembly 15 located at the water inlet pipe 5 is provided with a baffle plate 20 for backflow prevention, and the front end of the check valve component 16 is provided with a connecting part 21.
[0024] To elaborate further on the backflow prevention of the water inlet section, in the initial state, the water outlet 19 on the fixed part 18 is in a closed state. When the piston part 12 starts to move, the pressure inside the cylinder 2 changes, and its pressure is less than the external pressure. Liquid enters the cylinder 2 from the water inlet pipe 5, causing the baffle plate 20 to move into the cylinder 2. The return spring 17 is in a compressed state, and the water passage on the fixed part 18 is in a flowing state. The piston part 12 presses back, and the baffle part closes the water passage on the fixed part 18 again. Liquid flows into the water outlet 7 from the water passage pipe 6, thereby preventing the medium from flowing back from the water inlet pipe 5.
[0025] To further explain the backflow prevention of the water outlet 7, in the initial state, the water outlet hole 19 on the fixed part 18 is closed. When the medium enters the water outlet 7, the connecting part 21 at the rear end of the check member 16 is subjected to the pressure of the medium, causing the baffle plate 20 to move towards its front end. The return spring 17 is compressed, and the water passage hole on the fixed part 18 is open. When all the medium has flowed out, the return spring 17 rebounds, causing the baffle plate 20 to return to its original position and re-close the water passage hole on the fixed part 18, thereby preventing the medium from flowing back and improving the service life of the water pump.
[0026] To elaborate further, the rotating wheel 11 is configured as a cam structure, and the piston rod 13 is fixedly mounted on the rotating wheel 11. The rotation of the rotating wheel 11 drives the piston rod 13 to move, thereby causing the piston part 12 to reciprocate within the cylinder 2.
[0027] To elaborate further, a connecting gear 22 is provided on the motor shaft extending from the drive motor 4. The connecting gear 22 meshes with the drive gear 14 in the piston reciprocating mechanism 3 and controls its rotation.
[0028] To elaborate further, when the piston section 12 is in its initial state, the piston section 12 seals the water passage 6.
[0029] To elaborate further, there are three water outlet pipes 8 on the water outlet section 7, and the check valve assembly 15 of each water outlet pipe 8 has the same structure.
[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0031] Although this document frequently uses terms such as pump body 1, cylinder 2, piston reciprocating mechanism 3, drive motor 4, inlet pipe 5, through pipe 6, outlet section 7, outlet pipe 8, mounting bracket 9, connecting shaft 10, rotating wheel 11, piston section 12, piston rod 13, drive gear 14, check assembly 15, check piece 16, return spring 17, fixing part 18, outlet hole 19, baffle plate 20, connecting part 21, and connecting gear 22, the possibility of using other terms is not excluded.
