[0037] It should be noted that the specific angle between the first pump 1 and the second pump 2 is not limited in this embodiment, for example, the angle between the first pump 1 and the second pump 2 is α, 0 < α < 180°, and further, in some embodiments, 0 < α ≤ 90°. For example, as shown in the figure, the angle between the first pump 1 and the second pump 2 is 90°.

[0042] Further, in some embodiments, the first liquid outlet pipe 3 and the second liquid outlet pipe 4 are connected with the main pipeline 5, and the main pipeline 5 is connected with the total liquid outlet pipe 6.

[0043] That is, in the embodiment, the first liquid outlet pipe 3 and the second liquid outlet pipe 4 are collected through the main pipeline 5, so that the first liquid outlet pipe 3 and the second liquid outlet pipe 4 are both communicated with the total liquid outlet pipe 6 through the main pipeline 5, which is simple in structure and convenient in connection. At the same time, when the first pump 1 and the second pump 2 work at the same time, it is also beneficial to collect the fluids of the first liquid outlet pipe 3 and the second liquid outlet pipe 4 through the main pipeline 5 and then flow out through the total liquid outlet pipe 6.

[0044] In addition, in some embodiments, the second pump 2 and the second liquid outlet pipe 4 have a first preset distance along the second direction, the second pump 2 and the main pipeline 5 have a second preset distance along the third direction, and the second pump 2, the second liquid outlet pipe 4 and the main pipeline 5 form a first space.

Moreover, since the opening end of the groove structure 61 is not closed, the opening size of the groove structure 61 can have a proper deformation amount, so that the end of the total outlet pipe 6 away from the main pipe 5 has a certain position adjustment allowance to compensate for assembly errors.

[0048] In some embodiments, the first outlet pipe 3, the second outlet pipe 4, the main pipe 5 and the total outlet pipe 6 form an integrated structure, and a hose 7 is connected between the first outlet pipe 3 and the main pipe 5.
