[0050] In some embodiments, the liquid inlet connector part 104 includes a second end face of the volute body 11 and a second insertion part protruding from the second end face, and the liquid inlet port 106 is arranged on an end face of the second insertion part, and an outer circumferential surface of the second insertion part is provided with at least two second sealing grooves, each of which is provided with a sealing ring. That is, the liquid inlet connector part 104 can adopt the same structural design as the liquid outlet connector part 105 described above, and details are not repeated here.

[0051] In some embodiments, the liquid inlet joint portion 104 comprises a second end surface of the volute body 11, and the liquid inlet 106 is arranged on the second end surface. Unlike the above-mentioned embodiments in which the liquid inlet joint portion 104 comprises a protruding second insertion portion, the liquid inlet joint portion 104 of this embodiment does not comprise a second insertion portion, but directly uses the second end surface to connect with a corresponding device or pipeline, the device or pipeline is inserted into the liquid inlet 106 and can be sealed and connected by at least two sealing rings. For example, the liquid inlet channel 102 is provided with at least two second sealing grooves on the wall surface close to the liquid inlet 106, and each second sealing groove is provided with a sealing ring to seal and connect with the pipeline or device inserted into the liquid inlet 106. In other embodiments, the liquid outlet joint portion 105 can also adopt the same structural design as the above-mentioned liquid inlet joint portion 104, and details are not described here.

[0052] In some embodiments, the liquid inlet joint portion 104 and the liquid outlet joint portion 105 adopt different structural modes as described above. For example, the liquid outlet joint portion 105 comprises a first end surface 105a of the volute body 11 and a first insertion portion 105b protruding from the first end surface 105a, the liquid inlet 106 is arranged on the end surface of the first insertion portion 105b, and the outer peripheral surface of the first insertion portion 105b is provided with at least two first sealing grooves 105c, and each first sealing groove 105c is provided with a sealing ring. The liquid inlet joint portion 104 comprises a second end surface of the volute body 11, and the liquid inlet 106 is arranged on the second end surface. Only one of the liquid inlet joint portion 104 and the liquid outlet joint portion 105 is provided with an insertion portion, which can be used as a foolproof design to facilitate the differentiation between the liquid inlet joint portion 104 and the liquid outlet joint portion 105, and can also facilitate the separate assembly of the liquid inlet joint portion 104 and the liquid outlet joint portion 105.

[0053] In some embodiments, referring to Figure 2 , Figure 4 , Figure 8 , the volute body 11 is provided with a liquid outlet 113, the liquid outlet 113 is in communication with the liquid inlet channel 102, and the liquid outlet 113 can be provided with a sealing member 114 for closing or opening the liquid outlet 113. In this embodiment, the liquid outlet 113 is arranged on the volute body 11, that is, the volute is provided with the liquid outlet 113, and the liquid outlet 113 is in communication with the liquid inlet channel 102.

[0055] In some embodiments, the drain port 113 is arranged at the bottom end of the liquid inlet channel 102, and the position of the drain port 113 is lower than the bottom end of the volute cavity 101. It can be understood that the bottom end here refers to the relative position of the drain port 113 when the liquid pump is placed in a certain orientation, such as the axial horizontal placement of the liquid pump, and the position of the drain port 113 is at the bottom end. By arranging the drain port 113 at the bottom end of the liquid inlet channel 102 and lower than the bottom end of the volute cavity 101, the liquid can be smoothly discharged from the drain port 113 under the action of its own gravity, which facilitates the automatic discharge of the liquid in the liquid pump and prevents the liquid from remaining in the liquid pump.

[0056] In some embodiments, the volute body 11 includes a liquid inlet portion 11a and a liquid outlet connecting portion 11b, the liquid inlet channel 102 is formed in the liquid inlet portion 11a and the liquid outlet connecting portion 11b, one end of the liquid outlet connecting portion 11b is connected to the bottom end of the liquid inlet portion 11a, the drain port 113 is arranged at the other end of the liquid outlet connecting portion 11b, and the liquid outlet connecting portion 11b and the liquid inlet portion 11a form a preset angle.
