Detailed Description

The utility model is described in further detail below with reference to the attached drawings and detailed description: referring to fig. 1 to 3, a diaphragm chamber structure of a diaphragm pump includes a plurality of groups of pressurizing chambers 1 distributed uniformly in a ring shape, suction holes 10 and discharge holes 11 are provided on the pressurizing chambers 1, a side wall 2 is shared between two adjacent pressurizing chambers 1, and connecting ribs 3 connected with the bottom of the side wall 2 are provided in the pressurizing chambers 1 in a protruding manner.

In the above structure, the strength of the bottom of the side wall is increased by the connecting rib 3 protruding from the bottom of the side wall 2 in the pressurizing cavity 1, which can prevent the side wall from breaking along the bottom position, so that the thickness of the side wall can be further reduced under the condition of ensuring the strength of the side wall, and the volume of the pressurizing cavity can be further increased compared with the prior art.

Wherein the discharge hole 11 is positioned in the groove 4 formed by the two connecting ribs 3. Specifically, the end surface of the side wall 2 is convexly provided with first sealing ribs 101 which are vertically distributed. And a second sealing rib 102 is convexly arranged at the edge position of the diaphragm chamber, the first sealing rib 101 is connected with the second sealing rib 102, and the end surfaces of the first sealing rib 101 and the second sealing rib 102 are flush. The first sealing rib 101 and the second sealing rib 102 are used for forming a seal between the whole diaphragm chamber and the diaphragm sheet, and prevent mutual leakage between two adjacent pressurizing cavities 1.

Preferably, the side wall 2 includes a side wall middle portion 20 having a thin plate shape and side wall connecting ends 21 having an enlarged shape provided at both ends of the side wall middle portion 20, and the side wall middle portion 20 extends over a length greater than a sum of extension lengths of the two side wall connecting ends 21; the space occupied by the side wall 2 is further reduced in the structure, so that the volume of the whole pressurizing body is further increased. The plenum 1 comprises a connecting wall 22 connected to the outer ends of two adjacent side walls 2 and a bottom wall 23 at the bottom of the side walls 2 and the connecting wall 22; the connecting wall 22 is outwardly convex and curved.
