Of course, in the diaphragm pump of the present invention, the plug body can rotate to increase the volume of the water containing cavity 10 or decrease the volume of the water containing cavity 10, for example, in an embodiment, the pump body 1 is formed with the water containing cavity, the plug body is rotationally disposed in the water containing cavity, and the plug body has a spiral extrusion surface, so that the plug body rotates forward and backward, that is, the volume of the water containing cavity 10 can be increased or decreased by the spiral extrusion surface, or the plug body always keeps rotating in one direction, and the spiral extrusion surface can also increase the volume of the water containing cavity 10 or decrease the volume of the water containing cavity 10.
Alternatively, in another embodiment, the plug body can be moved along the axial direction of the water containing chamber 10 to change the volume of the water containing chamber 10. Such as a reciprocating push-pull plug, the volume of the water containing cavity 10 can be reduced or the volume of the water containing cavity 10 can be increased. Of course, the plug body may be disposed in the water containing cavity 10, or the plug body is an elastic sheet and covers only the cavity opening of the water containing cavity.
In addition, in the diaphragm pump of the present invention, the water containing cavity 10 between the plug body and the pump body 1 can be formed in multiple ways, for example, in one way, a concave portion is formed on the pump body 1, another concave portion is also formed on the plug body, and the two concave portions together form the water containing cavity 10, so that when the plug body is pushed and pulled, the volume of the water containing cavity 10 can be reduced or the volume of the water containing cavity 10 can be increased. Or, in another mode, the pump body 1 includes a concave cavity, and the plug body and the concave cavity form the water containing cavity 10, for example, the plug body can be arranged in the concave cavity to form the water containing cavity 10, or the plug body is an elastic sheet and only covers the cavity opening of the concave cavity to form the water containing cavity 10, so that the volume of the water containing cavity 10 can be reduced or the volume of the water containing cavity 10 can be increased when the elastic sheet is pushed and pulled.

Thus, the water inlet diaphragm 8 and the water outlet diaphragm 9 can be correspondingly operated by the action of the radial connecting strip 23.
Further, as shown in fig. 1, 2 and 3, and 6 and 7, the pump body 1 includes a base 24 and an end cover 25 connected to each other, the base 24 and the end cover 25 form the water inlet chamber 2 and the water outlet chamber 3 therebetween, the rim of the water inlet 4 is formed with an inwardly extending water inlet barrel 26, and the rim of the water outlet communication port 7 is formed with an inwardly extending water outlet barrel 27; the edge of diaphragm body 20 is clamped between the coupling faces of base 24 and end cap 25; the water inlet diaphragm 8 is covered on the water inlet cylinder 26, and the water outlet diaphragm 9 is covered on the water outlet cylinder 27. Thus, with this arrangement of the inlet and outlet cartridges 26, 27, it is easier for the inlet diaphragm 8 on the single diaphragm body 20 to act to close and open the inlet and the outlet diaphragm 9 to act to close and open the outlet communication port.
In addition, as shown in fig. 4, the diaphragm body 20 includes circumferential grooves 29 respectively located at the radial outer sides of the water inlet opening 21 and the water outlet opening 22, connecting arms 28 are formed between the water inlet opening 21 and the water outlet opening 22 and the respective corresponding circumferential grooves 29, and the water inlet diaphragm 8 and the water outlet diaphragm 9 are integrally connected with the respective corresponding connecting arms 28 through the respective radial connecting strips 23. In this way, the connecting arm 28 at the inlet membrane 8 is more easily pulled away by the inlet membrane 8, so that inlet water is more easily drawn into the inlet chamber from the circumferential groove 29.
