[0031] Refer toFigure 1 , a water pump, comprising a water pump main body 100, a pump sleeve and an interface dust-proof structure 400.

[0032] One end of the water pump main body 100 is provided with an output pipe 110 and an input pipe 120, and the other end of the water pump main body 100 is provided with a power cord 130.

[0033] The output pipe 110 and the input pipe 120 are arranged in parallel. In other embodiments, the output pipe 110 and the input pipe 120 can also be respectively arranged at both ends of the water pump main body 100 or the output pipe 110 and the input pipe 120 can be arranged on the side wall of the water pump main body 100, or the output pipe 110 and the input pipe 120 can be arranged in a form with a certain included angle. Those skilled in the art can select the specific positions of the output pipe 110 and the input pipe 120 according to actual needs.

[0034] In other embodiments, the wire, the output pipe 110 and the input pipe 120 can also be arranged at the same end of the water pump main body 100 at the same time. Those skilled in the art can select the positions of the wire, the output pipe 110 and the input pipe 120 according to actual needs.

[0035] One end of the power cord 130 is provided with a power interface, and the power interface is used to connect to a power source to supply power to the water pump.

[0036] The two ends of the interface dust-proof structure 400 are respectively set as a dust-proof end 410 and a wire-sheathing end 420, and the dust-proof end 410 and the wire-sheathing end 420 are movably connected. Specifically, in this embodiment, the interface dust-proof structure 400 is set as a soft rubber component, so that the dust-proof end 410 and the wire-sheathing end 420 can move relative to each other. In other embodiments, the dust-proof end 410 and the wire-sheathing end 420 can also be set in a form of being connected by a chain-like or rope-like structure. Those skilled in the art can select the specific structure of the interface dust-proof structure 400 according to actual needs. The power interface is inserted and matched with the interface jack. When the water pump is not needed (during the transportation and storage of the water pump), the power interface is inserted into the dust-proof end 410, and the dust-proof end 410 can protect the power interface, and can prevent external dust from entering the power interface, thereby avoiding poor contact between the power interface and the power source caused by dust, so as to ensure the normal operation of this water pump. Since the interface dust-proof structure 400 is set as a soft rubber component, the power interface can be smoothly inserted into the interface dust-proof structure 400, and it is not easy to cause damage to the power interface when the power interface is inserted into the interface dust-proof structure 400. The wire-sheathing end 420 is sleeved on the power cord 130, and the dust-proof end 410 is provided with an interface jack.

[0037] The pump sleeve is sleeved on the water pump main body 100. The pump sleeve includes a main sleeve body 200 and an end capping 300. Specifically, in this embodiment, the pump sleeve is provided as a silicone member. In other embodiments, the pump sleeve can also be provided as other conventional soft rubber members, and those skilled in the art can select the material of the pump sleeve according to actual needs.

[0038] End connection holes 210 and wire through holes are respectively formed at both ends of the main sleeve body 200.

[0039] A first sealing structure 211 is provided at the edge of the end connection hole 210. Specifically, the first sealing structure 211 includes a first sealing groove and a first sealing strip. The first sealing groove is provided as an annular groove structure, and the first sealing strip is provided as an annular protrusion structure. In other embodiments, the first sealing groove can also be provided as a rectangular groove structure, and the first sealing strip can be provided as a rectangular protrusion structure. Those skilled in the art can select the specific structure of the first sealing groove and the first sealing strip according to actual needs.

[0040] Specifically, a wire connection protrusion 220 is provided at the end of the main sleeve body 200. The wire connection protrusion 220 and the wire through hole are arranged at the same end of the main sleeve body 200, and the wire through hole penetrates through the wire connection protrusion 220. The power cord 130 of the water pump passes through the wire through hole.

[0041] Since the power cord 130 is a deformable member, by providing the wire connection protrusion 220, the contact area between the main sleeve body 200 and the power cord 130 can be increased, so that when the power cord 130 deforms, the main sleeve body 200 can still be in good contact with the power cord 130, thereby improving the sealing effect between the main sleeve body 200 and the power cord 130.

[0042] At the same time, by providing the wire connection protrusion 220, large deformation at the end of the power cord 130 can be avoided, thereby preventing the power cord 130 from being damaged due to excessive bending.

[0043] The end capping 300 is installed inside the end connection hole 210. The end capping 300 is provided as a soft rubber member. More specifically, the end capping 300 is also provided as a silicone member. In other embodiments, the end capping 300 can also be provided as other soft materials, or the end capping 300 can be provided as a hard material. Those skilled in the art can select the specific material of the end capping 300 according to actual needs.

[0044] A second sealing structure 310 is provided at the edge of the end capping 300, and the second sealing structure 310 is in sealing cooperation with the first sealing structure 211. The second sealing structure 310 includes a second sealing groove and a second sealing strip. The second sealing strip is correspondingly arranged with the first sealing groove, and the shape of the second sealing strip matches that of the first sealing groove. That is, in this embodiment, the second sealing strip is in a ring-shaped convex structure, and the second sealing strip is inserted and matched with the first sealing groove; the second sealing groove is correspondingly arranged with the first sealing strip, and the shape of the second sealing groove matches that of the first sealing strip. That is, in this embodiment, the second sealing groove is in an annular groove structure, and the second sealing groove is inserted and matched with the first sealing strip.

[0045] The end capping 300 is provided with input and output holes, and the number of the input and output holes is set to two. The two input and output holes respectively correspond to the input pipe 120 and the output pipe 110 of the water pump main body 100. The input pipe 120 and the output pipe 110 respectively pass through the two input and output holes.

[0046] When the pump sleeve is in use, first install the end capping 300 at the end of the water pump main body 100, and then insert the water pump main body 100 into the pump sleeve from the end connection hole 210. After the water pump main body 100 is completely inserted into the pump sleeve, the first sealing structure 211 and the second sealing structure 310 are hermetically connected, and the cooperation between the main sleeve body 200 and the end capping 300 can achieve a good waterproof effect.

[0047] Moreover, when installing the pump sleeve, the deformation amounts of the main sleeve body 200 and the end capping 300 are small, and there will be no situation where the main sleeve body 200 of the pump sleeve cannot be well restored due to excessive deformation amount. As a result, the pump sleeve can better fit the water pump main body 100, greatly improving the waterproof effect.

[0048] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
