After the first matching portion 131 and the second matching portion 132 are docked, in order to achieve a stable connection between the battery assembly 12 and the pump body assembly 11 without loosening, a limiting member 1323 needs to be provided in the embedding groove 1322, and a slot 1313 needs to be provided on the mounting wing 1312. After the mounting wing 1312 is inserted into the embedding groove 1322, it rotates in a predetermined direction until the limiting member 1323 is engaged with the slot 1313, so that stable fixation is achieved.

[0037] According to one embodiment of the present application, two mounting wings 1312 are provided, and the two mounting wings 1312 have different sizes and correspond to an embedding groove 1322 respectively, so that the battery assembly 12 can be installed in the pump body assembly 11 in a predetermined direction. Specifically, the two mounting wings 1312 are arranged in a one-to-one correspondence with the two embedding grooves 1322, and the sizes of the two mounting wings 1312 are different, so the sizes of the two embedding grooves 1322 arranged correspondingly thereto are also different. The mounting wings 1312 and the embedding grooves 1322 of different sizes are correspondingly rotated and snap-fitted, which can distinguish the positive and negative poles of the battery assembly 12 and avoid short circuits caused by connecting in the wrong position. For example, a larger-sized mounting wing 1312 can be set to correspond to the positive pole of the battery assembly 12, and a smaller-sized mounting wing 1312 can be set to correspond to the negative pole of the battery assembly 12.

[0038] According to one embodiment of the present application, referring to Figure 1 , the first mating portion 131 is arranged on the outer ring of the rotating output member 121, and the second mating portion 132 is arranged on the outer ring of the rotating input member 111; the rotating input member 111 includes a male connector, and the rotating output member 121 includes a female connector; the first mating portion 131 and the second mating portion 132 are relatively rotated and clamped, so that the male connector and the female connector are docked to realize the electrical connection between the pump body assembly 11 and the battery assembly 12. Specifically, the rotating output member 121 is arranged on the inner ring of the first mating portion 131, the rotating input member 111 is arranged on the inner ring of the second mating portion 132, the rotating input member 111 includes a male connector, and the rotating output member 121 includes a female connector. When the first mating portion 131 and the second mating portion 132 of the docking assembly 13 are relatively rotated and clamped, the male connector and the female connector are docked to realize the electrical connection between the pump body assembly 11 and the battery assembly 12. The male connector can be a banana head male connector with a wire, and the female connector can be a banana head female connector with a wire.

[0040] According to one embodiment of the present application, referring to Figure 2 The battery assembly 12 also includes a sealing groove 122 and a sealing ring 123. The sealing groove 122 is arranged on the outer ring of the first matching part 131, and the sealing ring 123 is embedded in the sealing groove 122 to seal the gap between the first matching part 131 and the second matching part 132 after relative rotation and clamping. Specifically, the pump body assembly 11 and the battery assembly 12 of the electric pump 10 are fixed after the first matching part 131 and the second matching part 132 of the docking assembly 13 are relatively rotated and clamped. The sealing ring 123 is arranged on the outer ring of the first matching part 131. When the first matching part 131 and the second matching part 132 rotate relative to each other, the sealing ring 123 is squeezed and deformed, which strengthens the fastening force between the first matching part 131 and the second matching part 132, and can also play a sealing role to prevent the battery assembly 12 from entering water, which is beneficial for the electric pump 10 to perform deep water rescue work. The sealing ring 123 can be a rubber ring or the like.

[0041] According to one embodiment of the present application, referring to Figure 6 , the rotating output member 121 is embedded in the battery assembly 12, and the battery assembly 12 also includes a sealant 124, which seals the gap between the rotating output member 121 and the battery assembly 12. Specifically, the output member 121 is embedded in the battery assembly 12, and when the first matching portion 131 and the second matching portion 132 are relatively rotated and connected, the output member 121 and the rotating input member 111 are docked to achieve electrical connection, and the sealant 124 is arranged around the output member 121. It can further prevent the battery assembly 12 from entering with water, reduce the risk of short circuit, and facilitate the electric pump 10 to perform deep water rescue work. The sealant 124 can be an epoxy sealant.

[0042] According to one embodiment of the present application, referring to Figure 7 The end of the battery assembly 12 away from the pump body assembly 11 includes a handle 14, and the handle 14 is used to extract the battery assembly 12. The pump body assembly 11 and the battery assembly 12 of the electric pump 10 in this embodiment are designed as separate bodies, and the two are connected by the docking assembly 13 to perform rescue work.

The display screen 15 is provided to facilitate timely observation of the battery power of the battery assembly 12 and timely replacement or charging, thereby avoiding affecting the normal rescue work of the electric pump 10 and improving the user experience.

[0044] In summary, the present application provides an amphibious electric pump 10, wherein the pump body assembly 11 and the battery assembly 12 of the electric pump 10 are split-type designs, and the two are connected by a docking assembly 13 for rescue work.

The embedding groove 1322 is corresponding to the mounting wing 1312. After the mounting wing 1312 is inserted into the embedding groove 1322, it rotates in a predetermined direction to achieve the fixation of the embedding groove 1322 and the mounting wing 1312. There are two mounting wings 1312, and the two mounting wings 1312 have different sizes and correspond to one embedding groove 1322 respectively. The mounting wings 1312 and the embedding groove 1322 of different sizes are rotated and connected correspondingly, so that the positive and negative poles of the battery assembly 12 can be distinguished to avoid short circuit caused by wrong connection. A sealing ring 123 is provided on the outer ring of the first matching part 131. When the first matching part 131 and the second matching part 132 rotate relative to each other, the sealing ring 123 is squeezed and deformed, which not only strengthens the fastening force between the first matching part 131 and the second matching part 132, but also plays a sealing role to prevent the battery assembly 12 from getting wet. The rotating output member 121 is embedded in the battery assembly 12. The battery assembly 12 also includes a sealant 124. The sealing rotating output member 121 is embedded in the gap of the battery assembly 12 to further prevent the battery assembly 12 from getting wet and reduce the risk of short circuit. When the electric pump 10 of the present application is working in deep water, the battery assembly 12 can be replaced underwater to meet the needs of long-term underwater rescue work and complete the rescue mission more efficiently and durably.
