Description

Technical Field

[0001] The utility model relates to the field of water purifier related equipment, in particular to a timed flushing device for an ultrafiltration water purifier. Background Art

[0002] Ultrafiltration water purifier is a device that can filter out suspended matter, colloids, microorganisms and other impurities in water. Its filtration accuracy is generally between 0.01-0.1 microns. In order to ensure the filtration effect and service life of the ultrafiltration water purifier, it needs to be flushed regularly to remove dirt and impurities on the filter element.

[0003] Traditional ultrafiltration water purifiers generally use manual flushing or timed flushing, but both methods have some shortcomings. Manual flushing requires users to operate regularly, which is troublesome; while timed flushing generally uses forward flushing or backwashing. For example, China Utility Model Patent No. CN214437132U uses backwashing to flush the filter element regularly and greatly improves the cleaning efficiency.

[0004] However, this method does not change the state of the water flow, so that when the water flow flushes the filter element, the entire impact is on the filter element, and the filter holes of the filter element are small. When the entire water flow is flushed, the cleaning effect is poor and water resources are wasted. Utility Model Content

[0005] The utility model aims to solve the problems in the background technology and proposes a timed flushing device for an ultrafiltration water purifier.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0016] 2. Water is stored in the cylinder and pressurized by a pressurizing mechanism, so that the water flow is concentratedly released in a short time to achieve a better flushing effect and save flushing water.

The device releases water flow in a concentrated manner in a short period of time to achieve a better flushing effect and save flushing water. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1:

[0024] Reference Figure 1-2 The timing flushing device of the ultrafiltration water purifier comprises a cylinder 1, a timing controller 2 is installed on the outer side of the cylinder 1, and a driving mechanism is provided on the cylinder 1;

[0025] The driving mechanism includes a motor 4, and the timing controller 2 is electrically connected to the motor 4, and the start and stop time of the motor 4 can be selected through the timing controller 2, and the motor 4 is located on the upper surface of the cylinder 1, and the output shaft of the motor 4 passes through the cylinder 1 and is connected to a reciprocating screw 5, and the reciprocating screw 5 is threadedly connected to a screw nut 6, and the screw nut 6 is slidably clamped on the inner wall of the cylinder 1, and the assembly plate 8 is installed on the bottom surface of the screw nut 6, the screw nut 6 includes a nut and two slide columns, and the nut and the two slide columns are U-shaped, and the two slide columns are symmetrically installed on the nut, and two slide grooves 9 are symmetrically opened on the inner wall of the cylinder 1, and each slide column is slidably connected in the slide groove 9 corresponding to the position, and the slide column is clamped in the slide groove 9 corresponding to the position, and then the screw nut 6 is limited to prevent it from rotating during the movement;

[0026] An assembly plate 8 is slidably connected in the cylinder 1, and a driving mechanism drives the assembly plate 8 to slide up and down. A first piston 10 is fixedly installed on the bottom surface of the assembly plate 8, and the first piston 10 contacts the inner wall of the cylinder 1, so that the first piston 10 and the cylinder 1 achieve a sealed space effect. A pressurizing mechanism is provided in the cylinder 1;

[0027] The pressurizing mechanism includes a truncated table 13, a hemispherical body 14 is slidably mounted in the truncated table 13, a support frame 11 is fixedly mounted in the cylinder 1, a spring 12 is mounted between the bottom surface of the support frame 11 and the top surface of the hemispherical body 14, the truncated table 13 cooperates with the first piston 10 to achieve a water storage effect in the cylinder 1, and the hemispherical body 14 is separated from the truncated table 13 to release the water source, thereby achieving a pressurized release effect;

[0028] The pressurizing mechanism includes a water baffle 18, an extension column 17 is fixedly installed on the bottom surface of the first piston 10, and the extension column 17 passes through the water baffle 18, and a second piston 19 is fixedly installed on the other end of the extension column 17. A through groove 20 is opened in the water baffle 18, and the diameter length of the second piston 19 is equal to the diameter length of the through groove 20, and the diameter length of the extension column 17 is less than the diameter length of the through groove 20. The pressurizing mechanism has a simple structure and is more convenient to use;

[0029] A water outlet plate 15 is provided in the cylinder 1, and a plurality of nozzles 16 are provided on the water outlet plate 15. The arrangement of the plurality of nozzles 16 can change the shape of the water flow, making it more dispersed and more impactful, so that the filter element can be cleaned more deeply. A water inlet pipe 3 is connected to the outside of the cylinder 1, and the water inlet pipe 3 is located between the first piston 10 and the pressurizing mechanism, ensuring that water storage space is realized in the cylinder 1 and the water source will not rise above the first piston 10.

[0030] When the utility model is used, firstly, the start time and the end time of the motor 4 are selected through the timing controller 2, and then when the start time is reached, the solenoid valve connected to the other end of the water inlet pipe 3 is opened, and water is injected into the cylinder 1 from the water inlet pipe 3, and the water is stored in the cylinder 1 through the round table 13 at the same time, and then the solenoid valve is closed, the motor 4 is started, and the reciprocating screw 5 is connected through the output shaft of the motor 4, so as to drive the reciprocating screw 5 to rotate, and then drive the screw nut 6 threadedly connected to the reciprocating screw 5 to move.

[0031] When the first piston 10 moves downward, the water source inside the cylinder 1 is squeezed, thereby increasing the internal pressure. When the first piston 10 continues to move downward, the internal water source squeezes the hemisphere 14 slidably mounted in the truncated platform 13, and then the hemisphere 14 is separated from the truncated platform 13, and then the water source inside the cylinder 1 passes through the truncated platform 13 and sprays downward onto the water outlet plate 15. The continuous movement of the first piston 10 makes the water source pass through the plurality of nozzles 16 in the water outlet plate 15, so that the water source sprayed out of the device has It has strong impact force and the water outlet is more delicate. It can deeply clean the filter in the water purifier to prevent impurities from clogging the filter and affecting the water outlet effect of the water purifier. It is worth mentioning that a support frame 11 is provided in the cylinder 1, and a spring 12 is installed between the support frame 11 and the hemisphere 14. When the water source in the cylinder 1 is completely released, the first piston 10 moves upward, and the hemisphere 14 is re-stuck between the truncated cones 13 under the action of the spring 12. At the same time, the solenoid valve is opened to re-inject water into the cylinder 1 for the next use.
