[0025] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0026] 1. A backwash and water-saving circulation mechanism is set up. Through the cooperation of the anti-overflow float, liquid level push rod, reset traction ring, tension spring, flow direction adjustment rod, water blocking plate and inner cross baffle ring, the flow direction adjustment rod is driven to slide according to the water level inside the sterile water tank, and the sealing direction inside the tee pipe is adjusted. At the same time, the sterile water remaining in the pipeline is discharged to prevent pollution to the pipeline. The discharged sterile water is stored in the backwash water tank for easy collection and utilization. When the water level inside the sterile water tank is too low, it is convenient for sterile water to enter the sterile water tank, thereby improving adaptability.

[0027] Through the cooperation of the water extraction pipe, secondary water supply pipe, uniform diversion pipe and permeation connecting pipe, water is sent into the reverse osmosis casing for permeation filtration to further treat impurities and bacteria in the water. Then, through the cooperation of the diversion inner pipe, centralized water pipe, irradiation tube, discharge elbow and tee pipe, the filtered water is centrally transported. During the transportation process, ultraviolet sterilization is carried out, realizing multiple treatments of water and improving the sterilization effect.

[0028] Through the cooperation of the backwash pipe and the backwash water pump, sterile water is sent into the centralized water pipe. Then, through the cooperation of the adjusting shaft sleeve, the limit gasket, the buoyancy lifting rod, the sealing float plate and the inner straight seal, the sterile water is evenly entered into the guide pipe, thereby reversely flushing the reverse osmosis casing. At the same time, the amount of water flushed for each reverse osmosis casing is equal, preventing the phenomenon of different flushing strengths, ensuring the cleaning efficiency, and completing the cleaning of all reverse osmosis casings simultaneously, thereby reducing the continuous water supply time, reducing the use of water resources, and improving the water-saving effect;

[0029] By adjusting the three-way connecting valve, the water after backwashing can be discharged into the sewage sedimentation tank through the sewage pipe for sedimentation. After sedimentation, the impurities are discharged, and the water is re-sent into the medicine mixing cylinder for processing through the circulation pump and the circulating water supply pipe, thereby improving the utilization rate of water resources. At the same time, because the collected sterile water is used for backwashing, the impurities in the water are reduced, ensuring the effect of recycling.

[0030] 2. A mixed sterilization and filtration mechanism is set up. Through the cooperation of the primary water inlet pipe, power water wheel, power transmission rod, bevel gear, feeding drum and conveying auger, the impact force of the water flow can be used to generate rotational power during the water delivery process, and drive the feeding drum and conveying auger to rotate, so as to evenly deliver the medicine according to the water intake, improve the convenience, prevent excessive one-time addition of medicine, and reduce the residual medicine.

[0031] The water and medicine are stirred by the cooperation of the rotating motor, the transmission traction rod, the cross slot, the cross rod and the stirring rod, thereby improving the mixing effect and enhancing the disinfection effect of the medicine on the water. At the same time, because the medicine mixing cylinder is funnel-shaped and the drainage port is small, the residence time of the water and medicine inside the medicine mixing cylinder is increased, further enhancing the mixing effect. In addition, the activated carbon particles inside the filling frame are used to adsorb and filter the disinfected water again, thereby enhancing the treatment effect and further reducing impurities, bacteria and microorganisms in the water.

[0032] Through the cooperation of the anti-overflow float, liquid level push rod and touch switch, the water supply pump and rotary motor are shut down in time after the preparation of sterile water is completed, thus realizing quantitative production. After the production is completed, the system automatically stops, thus improving the adaptability. At the same time, the electric telescopic rod rises with the material guide cover, sealing the dosing pipe and preventing calcium hypochlorite particles from falling into the drug mixing cylinder, thus saving resources and reducing waste.

[0033] In summary, through the coordination of backwashing and water-saving circulation mechanism and mixed sterilization and filtration mechanism, water is mixed, filtered, permeated through membrane and irradiated with ultraviolet rays, and multiple treatment methods are used to efficiently remove impurities and bacteria in the water. In addition, the preparation can be stopped in time according to needs, which increases adaptability. At the same time, the sterile water remaining in some equipment can be collected to reduce pollution to the pipeline. The collected sterile water can also be used for backwashing, which improves resource utilization and reduces impurities and bacteria in the backwash water, facilitates secondary circulation, and improves water saving.

In order to prevent excessive addition of drugs, a limit frame is installed on the top of the drug mixing cylinder 501, and one end of the power transmission rod 505 passes through one end of the limit frame.

In order to reduce resource waste, one end of the water suction pipe 429 is connected to the outside of the filter cylinder 520, and one end of the circulating water supply pipe 434 is connected to the outside of the drug mixing cylinder 501. The signal output end of the touch switch 523 is connected to the input end of the water supply pump 503, the electric telescopic rod 507 and the rotating motor 514.

[0063] The working principle and use process of the present invention are as follows: First, the water to be treated is fed into the medicine mixing cylinder 501 through the cooperation of the water supply pump 503 and the primary water inlet pipe 502. In the process of water delivery, the impact force of the water flow pushes the power water wheel 504 and the power transmission rod 505 to rotate, and then the power is diverted and transmitted through the bevel gear 511, driving the feeding drum 509 and the conveying auger 510 inside the dosing pipe 506 to rotate, thereby uniformly delivering the calcium hypochlorite particles inside the medicine storage hopper 512, facilitating the calcium hypochlorite The particles and water are mixed inside the drug mixing barrel 501. At the same time, the rotary motor 514 is started to rotate the drive traction rod 515. The cross slot 518 and the cross rod 519 are used to drive the stirring rod 517 to rotate, stirring the water and calcium hypochlorite particles. This improves the mixing effect, enhances the sterilization effect, and reduces the residual calcium hypochlorite particles. In addition, because the drug mixing barrel 501 is funnel-shaped, the time for the water and calcium hypochlorite particles to mix inside the drug mixing barrel 501 is increased, further ensuring the mixing effect.

[0064] The mixed and disinfected water enters the filter cartridge 520 and is then adsorbed and filtered by the activated carbon particles in the filling frame 521, further improving the water treatment effect and reducing impurities and bacteria.

[0065] Next, the water after adsorption and filtration is sent into the secondary water supply pipe 428 through the cooperation of the water supply pump 503 and the water extraction pipe 429. It is evenly transported to the inside of the reverse osmosis casing 3 through the cooperation of the uniform diversion pipe 427 and the permeation connecting pipe 426. It is filtered again through the reverse osmosis membrane to further treat impurities and bacteria in the water. The filtered water is sent into the interior of the centralized water pipe 402 through the inner guide pipe 401 and discharged into the interior of the irradiation cylinder 403. The water passing between the irradiation cylinder 403 and the annular separation cylinder 413 is sterilized by the ultraviolet germicidal lamp 414, completing the preparation of sterile water.

[0066] Next, the sterilized water is discharged into the sterile water tank 409 for storage through the cooperation of the discharge elbow 404 and the tee pipe 405. As the liquid level in the sterile water tank 409 rises, the anti-overflow float 411 and the liquid level push rod 410 are pushed up, forcing the top of the liquid level push rod 410 to contact the touch switch 523 on the fixed frame 522, thereby promptly shutting down the water supply pump 503 and the rotating motor 514, stopping the processing of sterile water, and preventing overflow due to excessive production. In addition, the electric telescopic rod 507 is lifted up with the material guide cover 508, sealing the dosing pipe 506, and preventing calcium hypochlorite particles from falling into the medicine mixing cylinder 501, thereby saving resources and reducing waste.

[0067] In addition, when the overflow prevention float 411 rises, the flow direction adjustment rod 407 loses traction, and the retractable feature of the tension spring 416 pushes the reset traction ring 415 and the flow direction adjustment rod 407 to slide along the inner cross baffle ring 406, so that the water blocking plate 408 on the side close to the sterile water tank 409 is tightly fitted with the inner cross baffle ring 406 to form a seal, while the water blocking plate 408 on the side close to the backwash water tank 417 is separated from the inner cross baffle ring 406 to release the seal, making it convenient to drain the residual water in the centralized water pipe 402 and the irradiation tube 403 into the backwash water tank 417 for storage and standby, thereby preventing water from accumulating inside the pipe and causing pollution;

[0068] Then, when the sterile water in the sterile water tank 409 is used, the overflow prevention float 411 loses its buoyancy and falls, and through the cooperation of the traction rope 412, the flow direction adjustment rod 407 is pulled to slide, so that the water blocking plate 408 close to the sterile water tank 409 is separated from the inner cross baffle ring 406, and the seal is released, while the water blocking plate 408 close to the backwash water tank 417 is fitted with the inner cross baffle ring 406 to perform a seal, so that when sterile water is prepared next time, water can be collected in the sterile water tank 409, which improves adaptability. After the sterile water tank 409 is filled, the remaining sterile water is discharged into the backwash water tank 417 again;

[0069] Then, when the sterile water in the backwash water tank 417 is stored to a certain level, the backwash valve 425 in the centralized water pipe 402 is rotated to seal the bottom end of the centralized water pipe 402, and the adjusting sleeve 420 is rotated at the same time. Through the cooperation of the limit gasket 422, the buoyancy lifting rod 421, the sealing float 423 and the inner straight sealing ring 424 are pushed up, so that the inner straight sealing ring 424 seals the guide inner pipe 401. Then, the backwash water pump 419 is turned on to send the sterile water in the backwash water tank 417 into the centralized water pipe 402 through the backwash pipe 418. As the sterile water in the centralized water pipe 402 accumulates, the sealing float 423, the buoyancy lifting rod 421 and the inner straight sealing ring 424 are pushed up along the adjusting sleeve 420 to release the seal on the guide inner pipe 401, so that the sterile water can synchronously reversely enter the reverse osmosis casing 3 for backwashing.

[0070] Next, the three-way connecting valve 431 is rotated to seal the water extraction pipe 429, facilitating the flow of impurities and bacteria during backwashing along the permeation connecting pipe 426, the uniform diversion pipe 427 and the secondary water supply pipe 428, and then sent along the sewage discharge pipe 432 to the sewage sedimentation tank 433 for storage. When the backwashing is completed, the adjusting sleeve 420 is rotated to lower and reset the buoyancy lifting rod 421 and the inner straight sealing ring 424, thereby releasing the blockage of the guide inner pipe 401 and sealing it with the backwashing pipe 418. At the same time, the backwashing valve 425 is rotated to discharge the remaining water into the backwashing water tank 417. The three-way connecting valve 431 is rotated to reset, the water extraction pipe 429 is opened, and the sewage discharge pipe 432 is sealed to facilitate subsequent permeation filtration.

[0071] Finally, after the water inside the sewage sedimentation tank 433 has settled for a period of time, the slag discharge port at the bottom is opened to discharge the precipitated impurities and part of the water. Then, through the cooperation of the circulating pump 430 and the circulating water supply pipe 434, the precipitated water inside the sewage sedimentation tank 433 is sent into the medicine mixing cylinder 501 and sterilized together with the water delivered by the primary water inlet pipe 502, thereby improving the utilization rate and reducing the waste of water resources.

[0072] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
