The utility model provides a function detection device of a spray head, wherein the spray head 1 is a spray head 1 with a wrench 4, the wrench 4 is buckled to pump the spray head, and the function detection device of the spray head comprises:
the spray head fixing device 10 is used for fixing the spray head 1, and the spray head fixing device 10 is used for fixing the spray head 1;
the wrench buckling device 11 is used for buckling the wrench 4 to pump the spray head;
the detection device 20, the detection device 20 includes an air pump 21 and an air path 22, one end of the air path 22 is connected with the air pump 21 through an electromagnetic valve 23, the other end is provided with a sealing joint 24 for connecting with the suction rod hole 2 (for simplicity and convenience, the hose part of the air path 22 connected with the sealing joint 24 is not shown), and the air path 22 is provided with a pressure sensor;
