The terminology used in the description of the present application solely for the purpose of describing a specific embodiment of the present application, and is not intended to be limiting of the present application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0045] The peristaltic pump 100 claimed in the present application is applied to a sweeping machine and used for supplying water and cleaning liquid to the sweeping machine. Of course, the peristaltic pump 100 of the present application can also be applied to other electrical appliances such as a scrubbing machine, which will not be described here.

[0046] As Figures 1 to 5As shown, the peristaltic pump 100 provided by an embodiment of the present application comprises a first pump pipe assembly 10, a first roller assembly 20, a second pump pipe assembly 30, a second roller assembly 40 and a driving mechanism 50. The first pump pipe assembly 10 comprises a first liquid inlet connector 11, a first pump pipe 12 and a liquid outlet connector 13. The first liquid inlet connector 11 is connected to and communicates with the liquid outlet connector 13 through the first pump pipe 12. The first roller assembly 20 cooperates with the first pump pipe 12 to extrude the first pump pipe 12. The second pump pipe assembly 30 comprises a second liquid inlet connector 31, a second pump pipe 32 and a transition connector 33. The second liquid inlet connector 31 is connected to and communicates with the transition connector 33 through the second pump pipe 32. The transition connector 33 further communicates with the liquid outlet connector 13, and the transition connector 33 can discharge liquid through the liquid outlet connector 13. The second roller assembly 40 cooperates with the second pump pipe 32 to extrude the second pump pipe 32. The driving mechanism 50 comprises a motor 51 and a transmission assembly 52. The motor 51 is drivingly connected to the first roller assembly 20 and the second roller assembly 40 through the transmission assembly 52, and is used to control the first liquid inlet connector 11 and the second liquid inlet connector 31 to selectively admit liquid. Here, the first liquid inlet connector 11 and the second liquid inlet connector 31 respectively communicate with different types of liquid.

[0047] As can be seen from the above, when the peristaltic pump 100 is in operation, the motor 51 can be controlled to rotate in forward and reverse directions to control the first liquid inlet connector 11 or the second liquid inlet connector 31 to admit liquid. Thus, the peristaltic pump 100 can be used to draw different types of liquid through the first liquid inlet connector 11 and the second liquid inlet connector 31, and discharge the liquid through the same liquid outlet connector 13.

That is, the transmission assembly 52 can utilize the structural characteristics of the one-way bearings to enable the transmission shaft 521 to drive the first one-way bearing 522 or the second one-way bearing 523 to rotate when rotating in forward and reverse directions. This can meet the use requirement of controlling the first liquid inlet connector 11 and the second liquid inlet connector 31 to selectively admit liquid.
