Therefore, the above terms cannot be understood as limiting this application.

[0021] Example 1: This embodiment provides a rainwater pump, such as Figure 1 、 Figure 2 As shown, the pump comprises a pump body 100, a pump tube 200, and a control box 300. The pump tube 200 is threaded through the control box 300, with one end of the pump tube 200 connected to the pump body 100. The control box 300 is provided with a power interface 310, which is connected to the pump body 100 via a power cord 311. The pump tube 200 is a rigid tube. In this embodiment, the pump body 100 comprises a housing 110 and a motor 120 located within the housing 110. The motor 120 is connected to the power cord 311. The housing 110 is provided with a first water inlet 111 and a first water outlet 112. The first water outlet 112 is connected to the water inlet end of the pump tube 200.

[0022] The pump body 100 is used to extract rainwater from the barrel; the pump tube 200 is used to guide the rainwater extracted by the pump body 100 to the outside of the barrel; the control box 300 is used to control the operation of the pump body 100; the pump tube 200 is a hard tube with high structural strength, not easy to break, and long service life. At the same time, the distance between the pump body 100 and the control box 300 is limited by the pump tube 200, and the length of the power cord 311 is greater than the distance between the pump body 100 and the control box 300. Even if the pump body 100 falls when placed in the barrel, the power cord 311 will not be torn off; the pump tube 200 is passed through the control box 300, so that the pump tube 200 and the control box 300 are relatively fixed. Only one of the pump tube 200 or the control box 300 needs to be fixed to the barrel wall, which makes installation and fixation more convenient; the overall use is more convenient and the service life is longer.

[0023] To ensure reliability, pump tube 200 includes a straight section 210 and a hook section 220. One end of straight section 210 is connected to one end of hook section 220, while the other end of straight section 210 is connected to pump body 100. A first angle is formed between straight section 210 and hook section 220. Straight section 210 guides water flow from the bottom to the top of the barrel, achieving high linear transport efficiency. Hook section 220 both guides water out of the barrel and can be hooked to the top of the barrel wall. In this embodiment, the first angle is 90°.

[0024] To ensure the reliability of pump tube 200, it also includes a water outlet section 230. The end of hook section 220, which is away from straight tube section 210, is connected to one end of water outlet section 230, forming a second angle between hook section 220 and water outlet section 230. Water outlet section 230 is used to guide the water outflow. In this embodiment, the second angle is greater than 90° and less than 180°.

[0025] In this embodiment, there is an arc transition between the straight pipe section 210 and the hook section 220 ; and there is an arc transition between the hook section 220 and the water outlet section 230 .

[0026] To accommodate buckets of varying heights, the straight tube section 210 includes a relatively retractable upper tube 211 and lower tube 212, with a connecting assembly 400 disposed between the upper and lower tubes 211, 212. In this embodiment, the lower tube 212 is threaded through the upper tube 211. The relative retractability of the upper and lower tubes 211, 212 allows for adjustment of the length of the straight tube section 210, enabling adaptation to buckets of varying heights and allowing the hook section 220 to be positioned at the top of the bucket wall for easier placement. The connecting assembly 400 connects the upper and lower tubes 211, 212, ensuring a secure connection after their relative retraction.

[0027] In order to connect the assembly 400 reliably, as Figure 3 As shown, the connecting assembly 400 includes a connecting sleeve 410, a fastening sleeve 420 and a locking sleeve 430. The upper end of the connecting sleeve 410 is connected to the upper tube 211, and the lower end of the connecting sleeve 410 extends out of the bottom of the upper tube 211. The fastening sleeve 420 is sleeved on the lower tube 212. The upper end of the fastening sleeve 420 is threadedly connected to the lower end of the connecting sleeve 410. The locking sleeve 430 is located between the fastening sleeve 420 and the lower tube 212. A fastening surface 421 is provided on the inner surface of the fastening sleeve 420, and the distance from the fastening surface 421 to the center gradually decreases from top to bottom; a first sealing member 440 is provided between the locking sleeve 430 and the lower tube 212. The connecting sleeve 410 is used to connect the upper tube 211 and the lower tube 212. The lower end of the connecting sleeve 410 extends out, that is, the interface between the upper tube 211 and the lower tube 212 is located on the connecting sleeve 410, the sealing and connection strength between the upper tube 211 and the lower tube 212 are better, and it is convenient to be threadedly connected with the fastening sleeve 420; the locking sleeve 430 is used to lock with the lower tube 212, and can also lock the lower tube 212 to prevent the upper tube 211 and the lower tube 212 from moving relative to each other; the fastening sleeve 420 is used to lock with the lower tube 212. The locking sleeve 430 is compressed so that the locking sleeve 430 presses the lower tube 212, thereby realizing the movable locking of the upper tube 211 and the lower tube 212; the design of the fastening surface 421 presses the locking sleeve 430 toward the lower tube 212 during the tightening process of the fastening sleeve 420, so that the locking sleeve 430 is also locked with the lower tube 212 while the fastening sleeve 420 is tightened; the design of the first sealing member 440 ensures the seal between the locking sleeve 430 and the lower tube 212, and prevents water from leaking therebetween.

[0028] In this embodiment, the first sealing member 440 is also located between the locking sleeve 430 and the connecting sleeve 410. The first sealing member 440 also improves the sealing between the locking sleeve 430 and the connecting sleeve 410 to prevent water from leaking therebetween. When the fastening sleeve 420 is tightened, the top surface of the locking sleeve 430 fits against the bottom surface of the connecting sleeve 410. A groove 432 is provided on the top surface of the locking sleeve 430. The first sealing member 440 is located on the groove 432. All four sides of the first sealing member 440 are restricted and squeezed, resulting in a better fit and sealing effect. A notch 431 is provided on the locking sleeve 430. The design of the notch 431 makes it easier for the fastening surface 421 to press the locking sleeve 430 against the lower tube 212.

[0029] In order to ensure the reliability of the connecting assembly 400, the connecting assembly 400 also includes a fixing sleeve 450, which is sleeved on the upper tube 211, and the upper end of the connecting sleeve 410 is threadedly connected to the fixing sleeve 450; the bottom surface of the upper tube 211 is provided with a first flange 213 bent outward, and the first flange 213 is located between the connecting sleeve 410 and the fixing sleeve 450; a second sealing member 460 is provided between the first flange 213 and the connecting sleeve 410; the top surface of the lower tube 212 is provided with a second flange 214 bent outward, and the maximum diameter of the second flange 214 is greater than the minimum diameter of the connecting sleeve 410. The fixing sleeve 450 is used to connect and fix the connecting sleeve 410 to the upper tube 211, and at the same time can strengthen the structural strength of the connection of the upper tube 211; the design of the first flange 213 can strengthen the structural strength of the upper tube 211, that is, it can strengthen the strength of the connection between the upper tube 211 and the lower tube 212. At the same time, the first flange 213 is used to fix the upper tube 211 and the connecting sleeve 410. The upper and lower surfaces of the first flange 213 are respectively fitted with the connecting sleeve 410 and the fixing sleeve 450, that is, the first flange 213 is clamped by the connecting sleeve 410 and the fixing sleeve 450, so that the upper tube 211 and the connecting sleeve 410 are relatively fixed; The design of the second sealing member 460 ensures the seal between the first flange 213 and the connecting sleeve 410, preventing water leakage therebetween; the design of the second flange 214 can strengthen the structural strength of the lower tube 212, that is, it can strengthen the strength of the connection between the upper tube 211 and the lower tube 212; the maximum diameter of the second flange 214 is greater than the minimum diameter of the connecting sleeve 410, so that the downward movement of the lower tube 212 will be limited by the connecting sleeve 410, preventing the lower tube 212 from falling out; at the same time, the maximum diameter of the second flange 214 is smaller than the diameter of the upper tube 211, ensuring that the relative sliding of the upper tube 211 and the lower tube 212 is reliable.

[0030] In order to ensure that the lower tube 212 is reliably connected to the pump body 100, Figure 4As shown, the bottom surface of the lower tube 212 is provided with a third flange 215 bent outward, a water outlet pipe 113 is provided on the pump body 100, and a mounting sleeve 130 is provided on the water outlet pipe 113. The upper end of the mounting sleeve 130 is sleeved on the bottom of the lower tube 212, and the lower end of the mounting sleeve 130 is connected to the water outlet pipe 113. The third flange 215 is located between the water outlet pipe 113 and the mounting sleeve 130; a fourth sealing member 140 is provided between the third flange 215 and the water outlet pipe 113. The design of the third flange 215 can strengthen the structural strength of the lower tube 212, that is, it can strengthen the structural strength of the connection between the lower tube 212 and the water outlet pipe 113. At the same time, the third flange 215 is used to fix the lower tube 212 and the installation sleeve 130. The third flange 215 is stuck between the water outlet pipe 113 and the installation sleeve 130, so that the lower tube 212 and the installation sleeve 130 are relatively fixed. The design of the water outlet pipe 113 facilitates the connection with the lower tube 212. The installation sleeve 130 is used to connect and fix the lower tube 212 and the water outlet pipe 113, while also strengthening the structural strength of the connection between the lower tube 212. The design of the fourth sealing member 140 ensures the seal between the third flange 215 and the water outlet pipe 113, preventing water from leaking between the two. The upper tube 211 and the lower tube 212 are detachable, and the lower tube 212 and the pump body 100 are detachable, making it easy to store when not in use.

[0031] In this embodiment, the mounting sleeve 130 is connected to the water outlet pipe 113 through threads; the first water outlet 112 is located on the water outlet pipe 113; the first seal 440, the second seal 460 and the fourth seal 140 are all O-rings; the first flange 213, the second flange 214 and the third flange 215 are all annular.
