[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, by Figures 1-5The utility model includes a pump casing 1, in which a movement 2 is installed, and shafts are provided at both ends of the movement 2. End covers 3 are connected to both ends of the pump casing 1, and a bearing frame 4 is provided on the inner side of the end cover 3. The bearing frame 4 is provided with six protrusions. A bearing 5 is embedded in the central shaft hole of the bearing frame 4, and an eccentric wheel 6 is embedded inside the bearing 5. The eccentric wheel 6 is connected to the shaft of the movement 2 and is used to convert the axial rotation of the shaft of the movement 2 into the up and down swing of the bearing frame 4. A pump casing bracket 7 is provided on one side of the bearing frame 4. Six through holes are distributed on the circumference of the pump casing bracket 7. The six protrusions on the bearing frame 4 pass through the six through holes respectively. A diaphragm 8 is provided on the inner side of the pump casing bracket 7, and an intermediate plate 9 is provided at one end of the diaphragm 8. Six suction valves 10 are provided on the circumference of the surface of the middle plate 9. A piston 11 is provided on one side of the six suction valves 10. The piston 11 is located in the corresponding chamber on the middle plate 9. A discharge valve 12 is provided in the central axis hole of the middle plate 9. An O-ring 13 is embedded on the outside of the discharge valve 12 and on the surface of the middle plate 9. One end of the middle plate 9 is connected to the pump head shell 14. A flower-shaped sealing ring 15 is provided on the contact surface between the pump head shell 14 and the middle plate 9. The flower-shaped sealing ring 15 is sleeved on the outside of the middle plate 9. A pressure relief cover 16 is embedded on one end of the outer wall of the pump head shell 14. The setting of the pressure relief cover 16 can automatically open and release the pressure when the pressure inside the pump body is too high, thereby protecting the pump body and the pipeline from damage.

[0022] The lower end of the pump housing 1 is connected to a support 17 , and the four corners of the support 17 are connected to shock-absorbing feet 18 .

[0023] The O-ring 13 and the flower-shaped sealing ring 15 are both made of silicone material, which has good elasticity and sealing performance, preventing fluid leakage and also helping to reduce noise.

[0024] Working principle: Inhalation phase

[0025] When the shaft of the movement 2 starts to rotate, the eccentric wheel 6 on the shaft also rotates. The rotation of the eccentric wheel 6 causes the bearing frame 4 to swing up and down. The six protrusions on the bearing frame 4 are limited by the six through holes on the pump housing bracket 7 to ensure the stability and direction of the swing.

[0026] The swing of the bearing frame 4 drives the diaphragm 8 to reciprocate. One end of the diaphragm 8 is connected to the middle plate 9. Therefore, the reciprocating motion of the diaphragm 8 pushes or pulls the piston 11 on the middle plate 9.

[0027] When the diaphragm 8 and the piston 11 move away from the suction valve 10, the volume of the corresponding chamber on the intermediate plate 9 increases, forming a negative pressure area. At this time, the suction valve 10 opens and the external fluid is sucked into the chamber.

[0028] When the diaphragm 8 and the piston 11 move toward the suction valve 10, the volume of the corresponding chamber on the intermediate plate 9 decreases, compressing the fluid;

[0029] As the pressure of the fluid in the chamber increases, the suction valve 10 automatically closes to prevent the fluid from flowing back;

[0030] At the same time, the discharge valve 12 gradually opens under the action of the fluid pressure, preparing for the discharge of the fluid;

[0031] When the fluid pressure in the chamber reaches a certain level, the discharge valve 12 is fully opened. At this time, the diaphragm 8 and the piston 11 continue to move toward the discharge valve 12, and the compressed fluid is discharged out of the pump through the discharge valve 12.

[0032] An O-ring 13 is embedded on the outside of the discharge valve 12 to ensure that the fluid does not leak during the discharge process. At the same time, a flower-shaped sealing ring 15 is provided on the contact surface between the pump head housing 14 and the intermediate plate 9 to further enhance the sealing effect.

[0033] The above-mentioned suction, compression and discharge stages constitute a complete pumping cycle. As the shaft of the movement 2 continues to rotate, the eccentric wheel 6, bearing frame 4, diaphragm 8 and piston 11 and other components will continuously repeat the above-mentioned movements to achieve continuous pumping of the fluid.

[0034] During the pumping process, if the internal pressure of the pump body is too high, the pressure relief cover 16 will automatically open to release part of the pressure and protect the pump body from damage.
