The utility model discloses a high-power
oral irrigator water pump capable of reducing pressure loss, which belongs to the technical field of
oral irrigator water pumps, and comprises a pump main body, a straight
pipe, a diaphragm upper cover, a first valve body and a second valve body, the straight
pipe is connected to the pump main body, the straight
pipe is butted with a diaphragm body on the pump main body, and the diaphragm upper cover is connected with the first valve body. The diaphragm upper cover and the first valve body are both installed in the straight pipe, the diaphragm upper cover is located between the first valve body and the diaphragm body, an expansion pipe communicated with the straight pipe is arranged on one side of the straight pipe, and the second valve body is arranged in the expansion pipe; the expansion pipe is arranged on one side of the straight pipe, the first valve body is installed in the expansion pipe, when the pumping main body drives the diaphragm body to suck the straight pipe, under the control action of the first valve body and the second valve body, water enters the straight pipe from the expansion pipe and then is directly pushed into the diaphragm upper cover to be flushed out, the
impact strength of the water is greatly improved, and the service life of the water pump is prolonged. Pressure loss is reduced, and water pump power is improved.
