The utility model discloses a pneumatic diaphragm pump convenient to clean, which relates to the field of diaphragm pumps, solves the problem that impurities in liquid easily block gaps between a valve ball and two sides of a connecting plunger and affect use of a device, and comprises a pneumatic diaphragm pump main body, the two sides of the pneumatic diaphragm pump main body are both provided with the connecting plunger; the top end and the bottom end of the inner wall of each connecting plunger are each provided with a valve ball, the two sides of each valve ball are each provided with a pushing mechanism, through mutual cooperation of the arranged pushing mechanisms and sliding mechanisms, gaps between the valve balls and the connecting plungers can be enlarged by pushing the push rods, meanwhile, the first connecting plates move downwards, impurities are scattered, and therefore the impurities are prevented from being separated. The problems that gaps between the valve ball and the two sides of the conn
