The water outlet pipe 2 is connected to the pump body 1, the impeller is arranged in the pump body 1, and the drive motor is used to drive the impeller to rotate; the water pump 100 also includes a water inlet mechanism 3, the water inlet mechanism 3 includes a pipe assembly 31, a cleaning assembly 32 and a collecting assembly 33; the pipe assembly 31 includes a four-way pipe 311, a filter screen 312, a first blocking member 313 and a second blocking member 314; the four-way pipe 311 includes a water section 3111, water inlet section 3112, installation section 3113 and recovery section 3114, the water discharge section 3111 and the water inlet section 3112 are arranged opposite to each other in the vertical direction, the installation section 3113 and the recovery section 3114 are arranged opposite to each other in the horizontal direction, the four-way pipe 311 has a common cavity 3115, the water discharge section 3111, the water inlet section 3112, the installation section 3113 and the recovery section 3114 are all connected to the common cavity 3115; the first blocking member 313 is used to block the installation section 3113 from the common cavity 3115. 115; the second blocking member 314 is used to block the end of the recovery section 3114 away from the common cavity 3115; the filter screen 312 is embedded in the end of the water inlet section 3112 facing the common cavity 3115, and the end of the water inlet section 3112 away from the common cavity 3115 is connected to the pump body 1; the cleaning assembly 32 includes a driving member 321, a connecting rod 322 and a scraper 323, the connecting rod 322 passes through the first blocking member 313 and is movably installed on the first blocking member 313, and the connecting rod 322 is The outer wall is sealedly connected to the first sealing member 313, one end of the connecting rod 322 is connected to the driving member 321, and the other end of the connecting rod 322 is connected to the scraper 323; the collecting assembly 33 includes a recovery bottle 331, and the recovery section 3114 is provided with a recovery port 31141 connected to the bottle mouth of the recovery bottle 331. The driving member 321 can drive the scraper 323 to move through the connecting rod 322, so that the scraper 323 can scrape off the blockage on the filter screen 312 and push the blockage to the recovery port 31141.

[0031] The filter screen 312 is a filter screen that is set up to filter the water entering the pump body 1, and impurities such as blockages are blocked outside the pump body 1, thereby reducing the probability of the pump body 1 being blocked by the blockages, and making the water pump 100 less likely to be blocked; and the present invention also adopts a driving member 321 to drive the scraper 323 to scrape off the blockages on the filter screen 312 through the connecting rod 322, thereby reducing the probability of the filter screen being blocked by the blockages, ensuring that the water flow out of the water section 3111 can pass through the filter screen 312 normally and flow into the pump body 1 from the water inlet section 3112 and then be discharged smoothly from the water outlet pipe 2, thereby ensuring the smooth drainage of the water pump 100; specifically, when the blockages accumulate at the filter screen 312 and block the filter screen 312, it makes it difficult for the water flow to pass through the filter screen 312 and enter In the water inlet section 3112, the driving member 321 can drive the scraper 323 to move rightward via the connecting rod 322. The scraper 323 moving rightward will scrape off the blockage on the filter screen 312 when passing through the filter screen 312. At this time, water can pass through the filter screen 312 normally and flow into the water inlet section 3112. The scraper 323 continues to move rightward, pushing the scraped blockage into the top of the recovery port 31141. Under the action of gravity, the blockage enters the recovery bottle 331 from the recovery port 31141. The recovery bottle 331 stores the blockage to prevent it from returning to the filter screen 312, further reducing the probability of the filter screen 312 being blocked, making the water pump 100 less likely to be blocked, and ensuring the smooth drainage of the water pump 100. It should be noted that after the water flows into the pump body 1 from the water inlet section 3112, the existing drive motor is used to drive the impeller to rotate, and the water flowing into the pump body 1 can be discharged from the water outlet pipe 2. It should also be noted that the first blocking member 313 and the second blocking member 314 can adopt existing plugs or rubber plugs, which are not limited here; in addition, the filter screen 312 can also be an existing filter screen 312, and the size of the filter holes on the filter screen 312 can be selected according to actual needs, which is not limited here; the filter screen 312 is generally a stainless steel filter screen 312 or a filter screen 312 coated with an oxidation-resistant coating; the driving member 321 can adopt an existing electric push rod or motor to realize the movement of the scraper 323 through the connecting rod 322; the connecting rod 322 can adopt an existing mechanical seal or a sealing ring seal to realize that the connecting rod 322 can be moved relative to the first blocking member 313, and can also be sealed with the first blocking member 313; for the scraper 323, the scraper 323 can adopt an existing silicone scraper 323, or an existing metal scraper 323; as for the recovery bottle 331, an existing container can be used, which is not limited here.

[0032] When the bottle 31 is in the air, it is rotated to move the bottle 31 out of the airtight container 312 so that the filter 310 can be easily removed.

[0033] In one embodiment, the recovery bottle 331 includes a bottle body 3311 and a filter cup 3312 disposed within the bottle body 3311. The bottle mouth of the bottle body 3311 is connected to the recovery port 31141. The top of the filter cup 3312 is provided with an opening facing the recovery port 31141. A receiving chamber 3313 is formed between the filter cup 3312 and the inner wall of the bottle body 3311. The bottom wall and / or side walls of the filter cup 3312 are provided with a plurality of filter holes connected to the receiving chamber 3313, so that water entering the filter cup 3312 from the recovery port 31141 can enter the receiving chamber 3313 through the filter holes. The filter cup 3312 can filter out water from the blockage to a certain extent, so that the blockage is contained in the filter cup 3312, while water flows into the receiving chamber 3313 through the filter holes. This allows the water and the blockage to be located in different chambers, achieving a certain degree of dry and wet separation and reducing the odor caused by the blockage.

[0034] In one embodiment, the collection assembly 33 further includes a return pipe 332, the top end of which is connected to the bottom of the accommodating chamber 3313, and the bottom end of which is connected to the water inlet section 3112, so that water in the accommodating chamber 3313 can enter the water inlet section 3112 through the return pipe 332. The provision of the return pipe 332 allows water in the accommodating chamber 3313 to enter the water inlet section 3112 through the return pipe 332, thereby preventing water from accumulating in the recovery bottle 331 and overflowing the bottle mouth, thereby resulting in poor recovery of clogged materials. The additional return pipe 332 can smoothly discharge water filtered by the filter cup 3312 out of the accommodating chamber 3313, thereby enhancing the dry-wet separation effect of the filter cup 3312 and more effectively reducing the odor caused by clogged materials.

[0035] In one embodiment, the bottle 3311 includes a detachably connected cover 33111 and a bottle body 33114. The filter cup 3312 is disposed on the bottle body 33114, and the filter cup 3312 and the bottle body 33114 form a receiving chamber 3313. The end of the cover 33111 away from the bottle body 33114 is connected to the recovery port 31141. The bottle body 33114 and the bottle cap can be connected by a threaded connection or a conventional buckle and slot. The bottle body 33114 can be removed from the cover 33111, thereby facilitating the user to clean out obstructions in the filter cup 3312 and preventing the obstructions from accumulating over time and overflowing from the bottle mouth, thereby clogging the filter screen 312.

[0036] In one embodiment, the cover 33111 includes a connecting portion 33112 and a rotating portion 33113 rotatably mounted on the connecting portion 33112. The end of the connecting portion 33112, distal from the rotating portion 33113, is connected to the recovery port 31141. The inner wall of the rotating portion 33113 is provided with internal threads, and the outer wall of the top of the bottle body 33114 is provided with external threads, with the internal threads being threadedly connected to the external threads. By rotating the rotating portion 33113, a user can independently rotate the rotating portion 33113 to release the threaded connection with the bottle body 33114, thereby preventing the recovery tube from being twisted or deformed by rotating the bottle body 33114. The rotating portion 33113 has a through hole for the connecting portion 33112 to pass through. A sealing ring is provided in the through hole, allowing the rotating portion 33113 to rotate relative to the connecting portion 33112 and preventing water from escaping from the rotating connection. This arrangement can be implemented using existing sealing and rotating structures. In addition, the threaded connection between the bottle body 33114 and the rotating part 33113 can also prevent the water in the bottle body 33114 from flowing out of the bottle body 33114 to a certain extent. Since the water in the bottle body 33114 will be discharged from the bottle body 33114 as soon as possible through the return pipe 332, the bottle body 33114 itself will basically not store water. Therefore, the bottle body 33114 and the rotating part 33113 can be directly connected by threads.

[0037] In one embodiment, the interior of the bottle body 33114 is inwardly convex to form a mounting step 33115. The outer edge of the top of the filter cup 3312 abuts against the mounting step 33115, enabling the mounting step 33115 to support the filter cup 3312. The mounting step 33115 of the bottle body 33114 provides reliable support for the filter cup 3312, facilitating installation and removal of the filter cup 3312. It should be noted that the filter cup 3312 has filter holes not only on its bottom wall but also on its side walls, providing a drainage path and facilitating the drainage of water within the filter cup 3312 into the accommodating chamber 3313.

[0038] In one embodiment, the driving member 321 is an electric push rod, and the output end of the electric push rod is connected to the connecting rod 322. The electric push rod can be implemented using an existing electric push rod, and the user can control the extension and retraction of the electric push rod through existing control technology.

[0039] In one embodiment, the water pump 100 further includes a control module and a flowmeter. The flowmeter is located in the water inlet section 3112 and is used to detect the flow rate in the water inlet section 3112. The drive member 321 and the flowmeter are both electrically connected to the control module. A conventional flowmeter is located in the water inlet section 3112 to determine the flow rate within the water inlet section 3112. If the filter 312 is clogged, the flow rate within the water inlet section 3112 will inevitably decrease. When the flow rate drops to a predetermined value, the conventional control module controls the electric push rod to extend, thereby driving the connecting rod 322 and scraper 323 to move rightward to clean the filter 312.

[0040] In one embodiment, the first sealing member 313 defines a through hole. The connecting rod 322 includes a rod body and multiple sealing rings sleeved onto the rod body. The sealing rings are spaced apart along the axial direction of the rod body. The inner ring of each sealing ring is sealed to the rod body, and the outer ring of each sealing ring is sealed to the wall of the through hole. The provision of multiple sealing rings improves the sealing between the rod body and the through hole, reducing the possibility of water leakage through the through hole.

[0041] In one embodiment, the radial cross-sections of the water discharge section 3111, the water inlet section 3112, the installation section 3113, and the recovery section 3114 are all rectangular. The water discharge section 3111, the water inlet section 3112, the installation section 3113, and the recovery section 3114 can be made of existing round or square tubes. The square tubes of the water discharge section 3111, the water inlet section 3112, the installation section 3113, and the recovery section 3114 allow the scraper 323 to be square, and the filter screen 312 can also be square. The scraper 323 fits the filter screen 312, thereby better scraping away blockages on the filter screen 312. It should be noted that the water discharge section 3111, the water inlet section 3112, the installation section 3113, and the recovery section 3114 can be connected to form the four-way pipe 311 using existing processes, or existing four-way pipes 311 can be used, without limitation herein.

[0042] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
