Embodiment 6 is applied to all the structures and method parts in embodiment 1, embodiment 2, embodiment 3, embodiment 4 or embodiment 5, referring to fig. 9-10, a self-priming non-clogging diaphragm pump further comprises that the diaphragm seat 2 is provided with two detachable diaphragm disks, the diaphragm 4 is fixed at a position between the two diaphragm disks, the middle position of one side of the diaphragm disk far away from the diaphragm 4 is provided with a quasi-spherical structure, the periphery of the outer wall of one side of the diaphragm disk near the diaphragm 4 is fixed with a plurality of contact pieces 27 with annular structures, the contact pieces 27 on the two diaphragm disks are arranged at intervals, one side of the contact piece 27 near the center of a circle is provided with an inclined surface, the thickness of the inclined surface is gradually increased towards one side far away from the center of a circle, one side of the contact piece 27 far away from the center of a circle is provided with an arc surface arched outwards, so that the diaphragm 4 placed at the middle position is pressed by the contact pieces 27 crossed at intervals, the diaphragm 4 is limited and fixed by utilizing the cambered surface on the outer side of the contact member 27, so that the fixing and stabilizing effect of the diaphragm 4 between the two diaphragm disks is improved.

Referring to fig. 9-10, in the present invention, the circumferential inner walls of the driving chamber 201 and the pump fluid chamber 202 are both provided with a connecting groove 28 distributed in an annular array on the side close to the diaphragm 4, the inner wall of the end of the connecting groove 28 away from the center of the circle is fixed with a connecting rod 29, the bottom of the outer wall of the connecting rod 29 is fixed with a limit bottom plate 30 and a limit top plate 31, the limit bottom plate 30 is located at the end close to the center of the diaphragm 4 in the connecting groove 28, the outer wall of the connecting rod 29 is located between the limit bottom plate 30 and the limit top plate 31 and is slidably connected with a third piston 32, the limit bottom plate 30 and the limit top plate 31 are both provided with a web structure, the top of the side of the connecting groove 28 close to the diaphragm 4 is provided with a plurality of air holes 2801, the air holes 2801 are located at the end of the limit top plate 31 away from the limit bottom plate 30, in actual use, when the diaphragm 4 deforms to the side of the movable plunger 5 for absorbing fluid, the edge of the side of the diaphragm 4 close to the driving chamber 201 deviates from the corresponding inner wall of the diaphragm seat 2 due to the pulling force, at this time, the third piston 32 in the connecting groove 28 corresponding to the driving cavity 201 moves inwards due to the extrusion of the air pressure, so that the corresponding air hole 2801 blows air to one side of the diaphragm 4, and the third piston 32 corresponding to the pump liquid cavity 202 moves outwards to suck air into the air hole 2801, so that the stability of fixing the edge position of the diaphragm 4 when the diaphragm 4 deforms is enhanced by utilizing the change of the air pressure of the side air hole 2801, and the air hole 2801 changes the air suction and blowing directions when the diaphragm 4 deforms to liquid out from one side of the pump liquid pipe 1, so that the stability of fixing the diaphragm 4 is further enhanced by utilizing the change of the air pressure, and the effectiveness of the diaphragm pump in long-term use is enhanced.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
