[0023] The connection frame 202 is sleeved outside the support plate 201 to stabilize the position of the motor 3 . The first damper 204 is connected to the two connection frames 202 through the stabilizing plate 203 , so as to achieve the effect of reducing the vibration of the motor 3 .

[0024] A circulating pump body 4 is installed on the right side of the motor 3, and a connecting component 5 is installed on the bottom surface of the circulating pump body 4. The connecting component 5 includes two fixed plates 501 arranged above the bottom plate 1, and the bottom surface of one of the two fixed plates 501 is connected to the upper surface of the buffer frame 601, and the upper surface of the other of the two fixed plates 501 is fixedly connected to a support block 502, and the upper surface of the support block 502 is connected to the outer surface of the circulating pump body 4.

[0025] The two fixing plates 501 have the same size and fit together. The lower fixing plate 501 can support the upper fixing plate 501 , thereby forming a support for the circulation pump body 4 .

[0026] Two groups of connection holes 503 are formed on the upper surface of each fixing plate 501 . A connection nail 504 is inserted into each group of connection holes 503 . A nut 505 is threadedly connected to the outer surface of each connection nail 504 .

[0027] The size of the connecting hole 503 is adapted to the connecting nail 504, and the connecting nail 504 will not shift inside the connecting hole 503. When the connecting nail 504 is tightened with the nut 505, the connection and fixation between the fixing plates 501 are completed, thereby fixing the circulating pump body 4.

At the same time, the second damper 605 will stabilize the buffer frame 601, so that the circulation pump body 4 can remain stable, thereby avoiding wear or loosening of parts of the circulation pump body 4 and extending its service life.
