A water storage chamber 5 is arranged at the lower part of the inner cavity of the pump body 1, and a nozzle 6 is communicated with the water storage chamber 5. The above structure constitutes a jet synchronous self-priming pump. When in use, first fill the pump body 1 with water, and then start the motor 3 to drive the impeller 4 to rotate. The impeller 4 pressurizes the water in the water storage chamber 5 and sprays it out from the nozzle 6 at a high speed, so as to form a negative pressure between the nozzle 6 and the impeller 4, thereby sucking and discharging air, and further realizing the self-priming water pumping of the pump body 1.

[0022] It should be noted that: the jet synchronous self-priming pump composed of the above structure is an existing device, and its specific operation principle has been made public. The specific structure can refer to Patent CN101644272A, and this application does not improve the specific operation structure of the jet synchronous self-priming pump, so it will not be elaborated here too much.

[0023] Reference Figures 1 to 3 As shown in the figure, a sound insulation cavity 7 is arranged inside the pump walls around the pump body 1, and argon gas 8 is filled in the sound insulation cavity 7. This structure forms a double-layer pump wall through the sound insulation cavity 7 to improve the sound insulation effect, and injecting argon gas 8 can further isolate the transmission of sound, and can effectively reduce the noise when the jet self-priming pump sprays water.
