Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: a pneumatic diaphragm pump high suction lift energy-saving device, including a pneumatic diaphragm pump main body 1, a water inlet pipe 2 and a water outlet pipe 3 fixedly connected to the surface of the pneumatic diaphragm pump main body 1, and a driving rod 4 slidably connected inside the pneumatic diaphragm pump main body 1. An extension box 5 is fixedly installed on the outer surface of the pneumatic diaphragm pump main body 1. A piston plate 6 is hermetically and slidably connected inside the extension box 5. A connecting rod 7 is fixedly installed at the center of the piston plate 6. One end of the connecting rod 7 away from the piston plate 6 is fixedly installed with an electromagnet 71. The end face of the driving rod 4 is fixedly connected with an iron plate 72. The surface of the electromagnet 71 is adsorbed on the surface of the iron plate 72. A sealing sleeve 73 is hermetically and slidably connected to the outer surface of the electromagnet 71. The outer surface of the sealing sleeve 73 is fixedly installed inside the pneumatic diaphragm pump main body 1 and the extension box 5. The outer surface of the connecting rod 7 penetrates and is movably connected inside the pneumatic diaphragm pump main body 1 and the extension box 5. An electric telescopic rod 8 is fixedly installed at the center of the outer surface of the extension box 5. By setting the electric telescopic rod 8 and the electromagnet 71, the actual use situation of the pneumatic diaphragm pump main body 1 can be flexibly selected for the extension requirement. Through the flexible selection of the extension requirement, the water output capacity and working efficiency of the pump are effectively improved, which is very beneficial for various industrial and commercial application scenarios, and improves the practicability and economy of the pump;
[0023] The output end of the electric telescopic rod 8 extends into the extension box 5 and is connected to the connecting rod 7. The output end of the electric telescopic rod 8 is hermetically and slidably connected inside the extension box 5. The bottom of the extension box 5 is fixedly connected with an input pipe 9. A first one-way valve 10 is fixedly installed inside the input pipe 9. One end of the input pipe 9 away from the extension box 5 is fixedly connected to the outer surface of the water inlet pipe 2. The inside of the water inlet pipe 2 is connected to the inside of the extension box 5 through the input pipe 9 and the first one-way valve 10. The top of the extension box 5 is fixedly installed with an output pipe 11. One end of the output pipe 11 away from the extension box 5 is fixedly connected to the surface of the water outlet pipe 3. The inside of the extension box 5 is connected to the inside of the water outlet pipe 3 through the output pipe 11. A second one-way valve 12 is fixedly installed inside the output pipe 11. By arranging the extension box 5 on both sides of the pneumatic diaphragm pump main body 1, when the connecting rod 7 is connected to the driving rod 4 through the electromagnet 71 and the iron plate 72, the movement of the driving rod 4 can also drive the piston plate 6 to slide inside the extension box 5, so that the liquid inside the water inlet pipe 2 can not only be pressed into the water outlet pipe 3 through the main cavity inside the pneumatic diaphragm pump main body 1 and the inside of the extension box 5 at the same time, which can increase the water output of the water outlet pipe 3, improve the overall suction lift of the pneumatic diaphragm pump main body 1, enable it to handle deeper or farther suction tasks, and enhance the actual application range and flexibility of the pump.
[0024] When it is necessary to increase the suction lift of the pneumatic diaphragm pump body 1, the electric telescopic rod 8 is started. The output end of the electric telescopic rod 8 abuts against the surface of the connecting rod 7 and drives the piston plate 6 to slide inside the range-increasing box 5, so that the end of the connecting rod 7 away from the piston plate 6 slides towards the driving rod 4. After the surface of the electromagnet 71 fits against the surface of the iron plate 72, the electromagnet 71 is started, so that the output end of the electromagnet 71 tightly adsorbs on the surface of the iron plate 72. Then the electric telescopic rod 8 is started, so that the output end of the electric telescopic rod 8 resets and moves away from the piston plate 6. During operation, when the driving rod 4 drives the diaphragm inside the pneumatic diaphragm pump body 1 to slide, the movement of the driving rod 4 can also drive the piston plate 6 to slide inside the range-increasing box 5, so that the liquid in the water inlet pipe 2 can not only be pressed into the water outlet pipe 3 through the main cavity inside the pneumatic diaphragm pump body 1 and the inside of the range-increasing box 5 at the same time, which can increase the water output of the water outlet pipe 3, improve the overall suction lift of the pneumatic diaphragm pump body 1, enable it to handle deeper or farther suction tasks, and enhance the actual application range and flexibility of the pump.
