DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-4 As shown, a liquid extraction device that is easy to use comprises: an extraction box 1, the inner top wall of the extraction box 1 is rotatably connected with a filter cartridge 2, the inner wall of the filter cartridge 2 is fixedly connected with a feed pipe 3, the surface of the feed pipe 3 is rotatably connected to the inner wall of the extraction box 1, the inner bottom wall of the extraction box 1 is fixedly connected with a guide plate 4, and the inner wall of the extraction box 1 is provided with a cleaning mechanism 5; wherein, the cleaning mechanism 5 comprises a water tank 51 fixedly connected to one side of the extraction box 1, the top of the water tank 51 is connected with a water pump 52, the top of the water pump 52 is connected with a nozzle 53, the inner wall of the nozzle 53 is connected with nozzles 54 distributed in equal rows, the surface of the nozzle 54 is provided with a liquid outlet hole 56, the inner wall of the filter cartridge 2 is provided with a blocking block 55, the inner wall of the extraction box 1 is provided with a cleaning assembly 57, the top of the blocking block 55 is conical, and a one-way valve 576 is embedded and installed on the surface of the nozzle 54.

[0025] A first gear is fixedly connected to the surface of the feed pipe 3 , a second gear is meshingly connected to the surface of the first gear, a servo motor is fixedly connected to the top of the second gear, and a surface of the servo motor is fixedly connected to the top of the extraction box 1 .

[0026] When the filter cartridge 2 needs to be cleaned, the water pump 52 and the servo motor are started. The output shaft of the servo motor rotates through the first gear and the second gear to drive the feed pipe 3 and the filter cartridge 2 to rotate. The water pump 52 draws water from the water tank 51 and transports it to the nozzle 53. The water in the nozzle 53 is transported to the nozzle 54. Since the shape of the nozzle 54 is truncated cone, the impact force of the water sprayed by the nozzle 54 is increased, so that the nozzle 54 flushes the surface of the filter cartridge 2, and it is more convenient to clean the impurities in the filter cartridge 2.

[0027] like Figure 2 As shown, the cleaning assembly 57 includes two first scrapers 571 fixedly connected to the top of the blocking block 55, and the inner wall of the first scraper 571 is slidably connected to the second scraper 572. One side of the first scraper 571 and the second scraper 572 contacts the inner wall of the filter cartridge 2.

[0028] The filter cartridge 2 contacts the first scraper 571 and the second scraper 572 during rotation, thereby causing impurities adhering to the inner wall of the filter cartridge 2 to fall off.

[0029] like Figure 2 As shown, the inner wall of the first scraper 571 is fixedly connected with a protective tube 573, the inner wall of the protective tube 573 is slidably connected with a protective rod 574, the top of the protective rod 574 is fixedly connected to the bottom of the second scraper 572, the bottom end of the protective rod 574 is fixedly connected with a spring 575, the bottom end of the spring 575 is fixedly connected to the inner bottom wall of the protective tube 573, the inner wall of the extraction box 1 is fixedly connected with an electric push rod 577, the telescopic end of the electric push rod 577 is fixedly connected to the bottom end of the blocking block 55, the inner wall of the guide plate 4 is fixedly connected with a sealing ring 578, the telescopic end of the electric push rod 577 is slidably connected to the inner wall of the sealing ring 578.

[0030] Start the electric push rod 577, and the telescopic end of the electric push rod 577 moves downward, driving the blocking block 55, the first scraper 571 and the second scraper 572 to move downward at the same time. At this time, the spring 575 has no external force resistance, and the elastic force of the spring 575 pushes the protective rod 574 and the second scraper 572 to move upward, ensuring that the first scraper 571 and the second scraper 572 can contact the inner wall of the filter cartridge 2, so that the bottom end of the filter cartridge 2 is opened, and then the impurities in the filter cartridge 2 fall out.

[0031] It should be noted that the servo motor, water pump 52, one-way valve 576 and electric push rod 577 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the servo motor, water pump 52 and electric push rod 577 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] When the utility model is in use, the electric push rod 577 is started, and the telescopic end of the electric push rod 577 moves downward, driving the blocking block 55, the first scraper 571 and the second scraper 572 to move downward at the same time, so that the bottom end of the filter cartridge 2 is opened, thereby causing impurities in the filter cartridge 2 to fall out, and the water pump 52 is started to drive the filter cartridge 2 to rotate. During the rotation, the filter cartridge 2 contacts the first scraper 571 and the second scraper 572, thereby causing impurities adhering to the inner wall of the filter cartridge 2 to fall off, and the water pump 52 draws water from the water tank 51 and transports it to the nozzle 53, and the water in the nozzle 53 is transported to the nozzle 54. Because the shape of the nozzle 54 is truncated cone-shaped, the impact force of the water sprayed by the nozzle 54 is increased, so that the nozzle 54 flushes the surface of the filter cartridge 2, and it is more convenient to clean the impurities in the filter cartridge 2.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
