Description

Technical Field

[0001] The invention relates to the technical field of household appliance manufacturing, in particular to a cleaning and filtering system for a water purifier. Background Art

[0002] A water purifier, also called a water purifier or a water purifier, is a water treatment device that deeply filters and purifies water according to the requirements for water use. Some water purifiers use ultrafiltration membranes to purify water, and the ultrafiltration membrane and its accessories belong to the cleaning and filtering mechanism of the water purifier.

[0003] When the cleaning and filtering mechanism of the existing water purifier is in use, it can achieve the purpose of self-cleaning by directly flushing the ultrafiltration membrane in some cases. However, the ultrafiltration membrane is composed of a large number of ultrafiltration membrane filaments. After the ultrafiltration membrane filaments adsorb many impurities, there is a certain adhesion between the membrane filaments. Direct flushing often cannot clean the membrane filaments in the middle position of the ultrafiltration membrane, resulting in poor self-cleaning effect. In addition, when discharging the cleaned sewage, the sewage may flow back, resulting in the inside of the water purifier not being cleaned. In view of the above problems, the inventor proposes a cleaning and filtering system for a water purifier to solve the above problems. Summary of the invention

[0040] A drainage mechanism 9 for draining away the waste water generated by the cleaning mechanism 4 cleaning the filtering mechanism 3 is provided at the bottom of the shell 1.

A sealing cover 905 that is snap-fitted with the drainage pipe 901 is fixedly provided at one end of the sliding rod 904. A spring 906 mounted on the sliding rod 904 is fixedly provided between the sealing cover 905 and the fixing bar 903. A water supply pipe 907 is connected to one side of the equipment box 902, so that the compressed spring 906 exerts a certain force on the sealing cover 905, so that the sealing cover 905 is against the end face of the drainage pipe 901.

[0041] The other end of the top of the top cover 2 is connected to a clean water pipe 10, and one side of the shell 1 is connected to a liquid inlet pipe 11. Solenoid valves are installed on the surfaces of the water supply pipe 907, the clean water pipe 10 and the liquid inlet pipe 11 (not drawn in the figure, this is the prior art and will not be repeated here). The solenoid valves are used to control the opening and closing of the water supply pipe 907, the clean water pipe 10 and the liquid inlet pipe 11, so that the filtered clean water is subjected to the action of external pressure, so that the external water source enters the shell 1 through the liquid inlet pipe 11.

[0042] Working principle: When the cleaning and filtering system is needed to clean and filter the external water source, the water source enters the shell 1 through the liquid inlet pipe 11, and the filtered water source first enters the ultrafiltration membrane 302, flows through the ultrafiltration membrane 302, and enters the cavity between the top cover 2 and the middle plate 301, and then the filtered water source in the cavity is pumped away by external pressure. At this time, the solenoid valve corresponding to the surface of the water supply pipe 907 is in a closed state, and the impurities in the water source adhere to the surface of the ultrafiltration membrane 302, thereby completing the cleaning and filtering operation of the water source;

[0043] When it is necessary to clean the impurities attached to the surface of the ultrafiltration membrane 302, the waterproof electric retractor 702 is started to shorten it, driving the connecting block and the square frame 703 to move upward in the vertical direction, thereby driving the movable rod 704, the movable bar 705 and the connecting bar 706 to move along the set trajectory, thereby driving the second I-shaped slide bar 414 to move in the direction of the ultrafiltration membrane 302, thereby driving the first I-shaped slide bar 409 and the middle rod 411 to move, thereby driving the vibration rod 412 to move in the direction of the ultrafiltration membrane 302 until the vibration rod 412 is inserted into the ultrafiltration membrane 302; the second motor 801 is started to rotate and drive the second connecting shaft 802 to rotate, thereby driving the square rod 803, the square tube 804 and the rotating ring 807 to rotate with the second connecting shaft 802 as the axis, and through the transmission action of the synchronous belt and the synchronous wheel, driving the third connecting shaft 805 to rotate, thereby driving the spur gear 808 to rotate with the third connecting shaft 805 as the axis. Then, the second gear ring 809, the sleeve 810 and the third gear ring 811 are driven to rotate with the first connecting shaft 602 as the axis, and then the first gear ring 404 is driven to rotate, and then the turntable 403 and the cylindrical pin 405 are driven to rotate with the first rotating shaft 402 as the center, and then the first grooved plate 410, the T-shaped slide plate and the first I-shaped slide bar 409 are driven to reciprocate along the surface of the second I-shaped slide bar 414, and then the vibration rod 412 is driven to reciprocate and vibrate, and then the ultrafiltration membrane 302 is driven to vibrate, and the first motor 601 is started to rotate to drive the first connecting shaft 602 to rotate, and then the screw rod 603 is driven to rotate with the first connecting shaft 602 as the axis, and then the lifting block 605 is driven to move downward in the vertical direction, and then the vibration rod 412 is driven to beat and vibrate the entire ultrafiltration membrane 302, so as to complete the cleaning of impurities on the surface of the ultrafiltration membrane 302 (at this time, the solenoid valves corresponding to the surfaces of the water purification pipe 10 and the liquid inlet pipe 11 are in a closed state);

[0044] When the vibration rod 412 is vibrating and cleaning the ultrafiltration membrane 302, the first rotating shaft 402 rotates to drive the third rotating shaft 506 to rotate, and through the transmission effect of the two bevel gears 505, the two fan blades 504 are driven to rotate around the second rotating shaft 503 as the axis, stirring the water source near the ultrafiltration membrane 302, so that the water source rushes toward the ultrafiltration membrane 302, speeding up the water flow velocity near the ultrafiltration membrane 302, and further enhancing the beating and cleaning effect of the vibration rod 412;

[0045] When the vibration rod 412 has finished beating and cleaning the ultrafiltration membrane 302 and it is necessary to discharge the wastewater inside the shell 1, the external pressure connected to the water supply pipe 907 is increased to a set value, so that the sewage inside the shell 1 can break open the sealing cover 905 under the action of pressure, flow through the drain pipe 901, the equipment box 902 and the water supply pipe 907, and be discharged to the external environment. After the sewage is discharged, the external pressure connected to the water supply pipe 907 is reduced to another set value, so that the water source no longer has the force to break open the sealing cover 905. The sealing cover 905 is tightly stuck on the end face of the drain pipe 901 under the action of the compressed spring 906, thereby preventing the sewage from flowing back.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
