Also includes a housing 5, the housing 5 is provided with duckbill check valve 6 and the connected water outlet 7, the check valve 6 and pump body 3 between the connected elbow 8. Check valve 6 reduces the internal water storage, and avoid backflow, duckbill check valve 6 is suitable for small flow drainage situation. The fixed frame 1 and housing 5 between fixed connection form closed chamber, the housing 5 in the bottom side position is provided with water inlet 9, the fixed frame 1 is Z-shaped structure, the fixed frame 1 has wide part 10 and narrow part 11, the ball float switch 4 is fixed on the narrow part 11 through fastener one 12, the motor 2 is fixed on the wide part 10, and the wide part 10 is also provided with power cord fixed through fastener two 13, the narrow part 11 is located at the horizontal plane lower than the horizontal plane where the wide part 10 is located, and the housing 5 is only provided with the open surface corresponding to the shape of the fixed frame 1. The water outlet 7 is higher than the water inlet 9 position, which is convenient for water to flow together, and then pumped out through the pump body 3. At the same time, the fixed frame 1 shape matches the structure design of high flow and low inlet. The embodiment is simple and ingenious, and the narrow part 11 position is the part occupying less length of the fixed frame 1, which provides installation for the ball float switch 4 and the matching parts, and fully utilizes the space. The power cord and the ball float switch 4 are clamped and limited through the accessories, which is beneficial to quick disassembly and assembly, and meets the fixed assembly needs. The water inlet 9 is provided with a filter screen, and the housing 5 is wrapped with a thermal insulation layer. The filter screen can prevent mosquitoes and foreign matters from entering, and the water outlet 7 can also prevent mosquitoes and foreign matters, and prevent odor.

[0019] The wide part 10 is provided with a second sliding groove 14 extending along the direction of the width of the fixed frame 1 at the outer edge, the fastener two 13 is slidably matched at the second sliding groove 14, and the fastener two 13 and the second sliding groove 14 are limited in the vertical direction. The narrow part 11 is provided with a first sliding groove 15 extending along the direction of the length of the fixed frame 1 at the outer edge, the fastener one 12 is slidably matched at the first sliding groove 15, and the fastener one 12 and the first sliding groove 15 are limited in the vertical direction. The fastener one 12 and the fastener two 13 are installed in the same way, slid into the corresponding groove from the side, and the size in the vertical direction is greater than the width of the groove to realize blocking and clamping limiting. Such structure is simple and reliable, and is relatively convenient for production and processing.

[0020] The wide part 10 is provided with a second connecting hole 16 at the end away from the narrow part 11, and the narrow part 11 is provided with a first connecting hole 17 at the end away from the wide part 10.
