[0016] The present invention provides a plasma sterilization device for a building pipeline direct drinking water system. It has the following beneficial effects:

[0017] First, the present invention rotates the rotating handle to adjust the primary gas delivery volume of the gas delivery pump. Then, water is sent into the water delivery pipe through the circulating water pump and the water inlet pipe, and then the flowing water is input into the overflow tank through the water delivery pipe. The flowing water impacts the paddle, causing the first rotating column to rotate through the paddle. The first rotating column drives the second rotating column to rotate through the second support column. The second rotating column starts the gas delivery pump, generating negative pressure in the gas delivery pipe, enabling the plasma generator to extract air from the atmosphere. After the air enters the plasma generator, under the electrocatalytic action of the plasma generator, the air is ionized to generate active groups, including high-energy electrons, hydroxyl groups, ozone, etc. The air containing active groups generated by the ionization of air in the plasma generator is continuously input into the first gas delivery tank through the gas delivery pump and the gas delivery pipe. The air containing active groups in the first gas delivery tank passes through the one-way valve and moves into the paddle, and then the rotating paddle evenly disperses the air containing active groups into the flowing water in the overflow tank, enabling the air containing active groups to be evenly mixed with the flowing water. Then, the evenly mixed flowing water enters the micro-nano generator and is micronized and nano-sized through the micro-nano generator to form micro-nano bubbles. The micro-nano bubbles can exist in water for a long time, thereby forming a long-term disinfection and killing function for bacteria and microorganisms in the water. Then, the flowing water containing micro-nano bubbles is transported to the designated location through the water outlet pipe, which can fully meet the time requirements for disinfecting the full-circulation pipeline without the use of drugs.

[0018] When the present invention needs to adjust the primary gas delivery volume of the gas delivery pump, it can be achieved by rotating the handle to adjust the space between the baffle and the rotating ring, thereby adjusting the primary gas delivery volume of the gas delivery pump. The primary gas delivery volume of the gas delivery pump can be flexibly adjusted according to the magnitude of the flowing volume of the flowing water, expanding the scope of application. Moreover, the gas delivery efficiency of the gas delivery pump can be automatically adjusted according to the flow rate of the flowing water, facilitating the uniform mixing of the air containing active groups and the flowing water, realizing the dynamic mixing of the active groups and water, and significantly improving the disinfection efficiency.

[0019] The present invention inputs the air containing active groups into the third gas delivery tank through the first gas delivery tank, and evenly disperses the air containing active groups in the third gas delivery tank into the flowing water in the overflow tank through a plurality of air outlet holes, increasing the mixing uniformity.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figure 1 shown, an embodiment of the present invention provides a plasma sterilization device for a building pipeline direct drinking water system, including a bracket 1, on which a circulating water pump 2 and a plasma generator 3 are arranged. An inlet pipe 7 and a water delivery pipe 4 are arranged on the circulating water pump 2. A mixing assembly 5 is arranged on one side of the water delivery pipe 4. An outlet pipe 6 is arranged on one side of the mixing assembly 5. An air suction port 8 is arranged on one side of the plasma generator 3.

[0031] As Figure 2 shown, the mixing assembly 5 includes an assembly base 501, on which a water passing trough 502 is arranged. A micro-nano generator 5014 is arranged on one side of the assembly base 501 close to the outlet pipe 6. A fixing block 503 is arranged in the water passing trough 502. A plurality of first support columns 504 are fixedly arranged on the outer wall surface of the fixing block 503. An air delivery pump 505 and an air delivery pipe 507 are arranged on the fixing block 503. A rotating handle 506 is arranged on one side of the air delivery pump 505;

[0032] A first rotating column 508 is rotatably arranged on one side of the fixing block 503 close to the micro-nano generator 5014. A first air delivery groove 509 is arranged on the first rotating column 508. A second support column 5010 and a one-way valve 5011 are fixedly installed in the first air delivery groove 509. A second rotating column 5012 is fixedly arranged on the second support column 5010. A plurality of blades 5013 are fixedly arranged on the side of the first rotating column 508 away from the fixing block 503.

[0033] Through the above technical solution, first, rotate the rotating handle 506 to adjust the primary gas delivery volume of the gas delivery pump 505. Then, input running water into the water trough 502 through the water delivery pipe 4. Subsequently, the running water impacts the paddle 5013, causing the first rotating column 508 to rotate through the paddle 5013. The first rotating column 508 drives the second rotating column 5012 to rotate through the second support column 5010. The second rotating column 5012 starts the gas delivery pump 505, and continuously inputs the air containing active groups generated by ionizing air in the plasma generator 3 into the first gas delivery trough 509 through the gas delivery pump 505 and the gas delivery pipe 507. The air containing active groups in the first gas delivery trough 509 moves through the one-way valve 5011 to the paddle 5013. The one-way valve 5011 is used to prevent the running water in the first gas delivery trough 509 from backflushing to the gas delivery pump 505. Then, the rotating paddle 5013 evenly disperses the air containing active groups into the running water in the water trough 502, so that the air containing active groups is evenly mixed with the running water. Then, the evenly mixed running water enters the micro-nano generator 5014 and is micronized and nano-sized through the micro-nano generator 5014 to form micro-nano bubbles. The micro-nano bubbles can exist in water for a long time, thereby forming a long-term disinfection function for bacteria and microorganisms in the water.

[0034] As Figures 3 to 6 shown, the gas delivery pump 505 includes a gas delivery pump base 50501. A rotating groove 50502 is provided on the gas delivery pump base 50501. A rotating ring 50503 is rotatably provided in the rotating groove 50502. An annular groove 50504 and a plurality of first sliding grooves 50505 are provided on the rotating ring 50503. An annular limiting block 50523 is provided in the annular groove 50504. An air cavity 50506 is provided on one side of the rotating groove 50502. A baffle 50507 is slidably provided in the air cavity 50506. A rotor 50508 is rotatably provided on the baffle 50507. A first air inlet 50509 and a first air outlet 50510 are respectively provided on both sides of the air cavity 50506. A first guiding sliding groove 50511 is provided on the side of the air cavity 50506 away from the rotating groove 50502. A first guiding sliding column 50512 is slidably provided in the first guiding sliding groove 50511. A second guiding sliding groove 50513 is provided on the side of the rotor 50508 close to the second rotating column 5012. A second guiding sliding column 50514 is slidably provided in the second guiding sliding groove 50513. A third rotating column 50515 is fixedly provided on one side of the second guiding sliding column 50514. The third rotating column 50515 rotatably penetrates through one side of the gas delivery pump base 50501;

[0035] On one side of the rotor 50508 away from the third rotating column 50515, a push column 50516 is rotatably arranged. A tooth groove 50517 is arranged on the push column 50516. A gear 50518 is meshed on one side of the tooth groove 50517. A fourth rotating column 50519 is arranged on the gear 50518. A worm gear 50520 is arranged on the fourth rotating column 50519. A worm 50521 is meshed on one side of the worm gear 50520. A fifth rotating column 50522 is arranged on the worm 50521. A number of second sliding grooves 50524 are arranged on the rotor 50508. A sliding piece 50525 is slidably arranged in the second sliding groove 50524. A number of third guiding sliding grooves 50526 and a number of first springs 50527 are arranged on the sliding piece 50525. A third guiding sliding column 50528 is slidably arranged in the third guiding sliding groove 50526. The first spring 50527 and the third guiding sliding column 50528 are fixedly installed in the second sliding groove 50524. A second air delivery groove 50529 is arranged on one side of the air cavity 50506.

[0036] Through the above technical solution, when it is necessary to adjust the primary air delivery volume of the air delivery pump 505, it is realized that the fifth rotating column 50522 is driven to rotate by rotating the handle 506. The fifth rotating column 50522 drives the worm 50521 to rotate. The worm 50521 drives the worm gear 50520 to rotate. The worm gear 50520 drives the gear 50518 to rotate through the fourth rotating column 50519. The gear 50518 makes the push column 50516 move through the tooth groove 50517. Since the push column 50516 is rotatably connected to the rotor 50508, the push column 50516 can drive the rotor 50508 to translate, adjust the position of the rotor 50508. The rotor 50508 drives the sliding piece 50525 and the baffle 50507 to move, adjust the space between the baffle 50507 and the rotating ring 50503, so as to adjust the primary air delivery volume of the air delivery pump 505. The primary air delivery volume of the air delivery pump 505 can be flexibly adjusted according to the magnitude of the flowing water volume, expanding the scope of application, and preventing the rotor 50508 from accidentally moving through the one-way transmission of the worm 50521 and the worm gear 50520;

[0037] When the second rotating column 5012 rotates, the second rotating column 5012 drives the third rotating column 50515 to rotate, the third rotating column 50515 drives the second guiding slide column 50514 to rotate, and then the rotor 50508 rotates through the square second guiding slide column 50514 and the square second guiding slide groove 50513. At the same time, the rotor 50508 presses the inner wall surface of the first slide groove 50505 through the sliding vane 50525, so that the rotating ring 50503 rotates following the rotor 50508. The rotor 50508 is rotatably connected to the push column 50516 and the baffle 50507. Therefore, the push column 50516 and the baffle 50507 do not hinder the rotation of the rotor 50508, and the first guiding slide groove 50511 and the first guiding slide column 50512 are used to prevent the baffle 50507 from rotating. The sliding vane 50525 is thrown out of the second slide groove 50524 under the action of centrifugal force, and its end is closely attached to the inner surface of the air chamber 50506, dividing the air chamber 50506 into several fan-shaped small chambers. As the rotor 50508 continuously rotates, the volume of the fan-shaped small chambers changes cyclically from large to small, and the first spring 50527 is used to enable the sliding vane 50525 to automatically extend and contract for compensation, compressing the air containing active groups entering the fan-shaped small chambers from the first air inlet 50509, and finally discharging it to the first air delivery groove 509 through the first air outlet 50510;

[0038] And because the third rotating column 50515 is connected to the second rotating column 5012, and the second rotating column 5012 is connected to the first rotating column 508 through the second support column 5010, the faster the flow rate of the flowing water is, the faster the paddle 5013 drives the first rotating column 508 to rotate, and the faster the first rotating column 508 drives the third rotating column 50515 to rotate through the second support column 5010 and the second rotating column 5012, and the faster the third rotating column 50515 drives the rotor 50508 to rotate through the second guiding slide column 50514 and the second guiding slide groove 50513. Thus, the higher the air delivery efficiency of the air delivery pump 505 is, and the air delivery efficiency of the air delivery pump 505 can be automatically adjusted according to the flow rate of the flowing water, which is convenient for the air containing active groups to be mixed evenly with the flowing water, realizing the dynamic mixing of the active groups and water, and significantly improving the sterilization efficiency.

[0039] As Figure 7 shown, the one-way valve 5011 includes a one-way valve base 501101, a second air inlet 501102 and a second air outlet 501103 are arranged on the one-way valve base 501101, an air passing groove 501104 is arranged between the second air inlet 501102 and the second air outlet 501103, a second spring 501105 is fixedly installed in the air passing groove 501104, and a sealing plate 501106 is fixedly arranged on the second spring 501105.

[0040] Through the above technical solution, when the air containing active groups in the first air delivery groove 509 moves towards the blade 5013, the air containing active groups enters the second air inlet 501102. The second air inlet 501102 presses the sealing plate 501106, causing the sealing plate 501106 to move towards the second air outlet 501103. The second spring 501105 deforms, releasing the sealing of the second air inlet 501102 by the sealing plate 501106. The air containing active groups in the second air inlet 501102 passes through the air passage groove 501104 and enters the second air outlet 501103. The air containing active groups passes through the second air outlet 501103 and continues to move towards the blade 5013. When the air containing active groups no longer moves towards the blade 5013, the sealing plate 501106 is no longer pressed, and the second spring 501105 rebounds, causing the sealing plate 501106 to return to its original position. The sealing plate 501106 is used to seal the second air inlet 501102 again, thereby preventing the flowing water in the first air delivery groove 509 from flushing back to the air delivery pump 505.

[0041] As Figure 8 shown, the blade 5013 includes a blade base 501301. A third air delivery groove 501302 and a plurality of air outlet holes 501303 are provided on the blade base 501301. The air outlet holes 501303 communicate with the third air delivery groove 501302.

[0042] Through the above technical solution, the air containing active groups is input into the third air delivery groove 501302 through the first air delivery groove 509, and the air containing active groups in the third air delivery groove 501302 is evenly dispersed into the flowing water in the water passage groove 502 through the plurality of air outlet holes 501303, increasing the mixing uniformity.

[0043] Working principle:

[0044] In the present invention, first, the rotation handle 506 is rotated to adjust the primary gas delivery volume of the gas delivery pump 505. Then, water is sent into the water delivery pipe 4 through the circulating water pump 2 and the water inlet pipe 7, and then the flowing water is input into the water passing trough 502 through the water delivery pipe 4. The flowing water impacts the paddle 5013, and the first rotating column 508 is rotated by the paddle 5013. The first rotating column 508 drives the second rotating column 5012 to rotate through the second support column 5010. The second rotating column 5012 starts the gas delivery pump 505, generating negative pressure in the gas delivery pipe 507, causing the plasma generator 3 to extract air from the atmosphere. After the air enters the plasma generator 3, under the electrocatalytic action of the plasma generator 3, the air is ionized to generate active groups, including high-energy electrons, hydroxyl groups, ozone, etc. The air containing active groups generated by the ionization of the air in the plasma generator 3 is continuously input into the first gas delivery trough 509 through the gas delivery pump 505 and the gas delivery pipe 507. The air containing active groups in the first gas delivery trough 509 passes through the one-way valve 5011 and moves into the paddle 5013. Then, the rotating paddle 5013 evenly disperses the air containing active groups into the flowing water in the water passing trough 502, enabling the air containing active groups to be evenly mixed with the flowing water. Then, the evenly mixed flowing water enters the micro-nano generator 5014 and is micro-nanoized through the micro-nano generator 5014 to form micro-nano bubbles. The micro-nano bubbles can exist in water for a long time, thereby forming a long-term disinfection function for bacteria and microorganisms in the water. Then, the flowing water containing micro-nano bubbles is transported to a designated location through the water outlet pipe 6, which can fully meet the time requirements for sterilizing the full-circulation pipeline without the use of drugs.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
