Description

Technical Field

[0001] The present invention relates to the technical field of disinfectant mixing, and particularly to a disinfectant preparation device. Background Art

[0002] When preparing disinfectants, sodium hypochlorite or sodium hypochlorite is usually used to increase the chlorine content in the disinfectant. Sodium hypochlorite has strong oxidizing properties and can hydrolyze to form hypochlorous acid with strong oxidizing properties, which can oxidize substances with reducing properties, causing microorganisms to ultimately lose their functions and be unable to reproduce or infect. Since sodium hypochlorite is very easy to fuse and react with water, and can effectively kill bacteria and viruses, sodium hypochlorite is mostly used as the main material in the production and manufacture of disinfectants.

[0003] In the prior art, a quaternary ammonium salt disinfectant preparation device with a defoaming function disclosed in CN116272528A has a drive motor whose output shaft is fixedly connected to a transmission shaft at one end passing through the inner cavity of the dispensing barrel. Symmetrically fixed to the outer surface of the transmission shaft are support columns, and one end of the support column is fixedly connected to the inner wall of the inner barrel body. Fixed to the outer surface of the transmission shaft are blades. In the prior art, the disinfectant is stirred by using the blades. When the blades rotate, cavities will be generated in the disinfectant due to high shear force, which will cause a large amount of the disinfectant to come into contact with air. And due to the repeated appearance of cavities, the liquid level of the disinfectant will fluctuate greatly, which will also cause the accelerated volatilization of some components of the disinfectant, thus affecting the disinfection effect of the disinfectant. At the same time, since the blades are always in the same plane, stirring only by the blades will result in some dead corners not being stirred due to the small stirring area, thus causing uneven stirring.

[0004] Considering that solid substances such as sodium hypochlorite are added when preparing disinfectants, it is usually necessary to stir the disinfectant to accelerate the mixing of the disinfectant. In the prior art, an impeller is usually used to rotate in the disinfectant during stirring. The stirring area using the impeller is small, and there may be some dead corners that cannot be stirred, resulting in uneven diffusion of some components of the disinfectant. During stirring, cavities may be generated in the disinfectant due to the high shear force of the impeller, and a large amount of the disinfectant will come into contact with air, resulting in the generation of bubbles. Due to the presence of bubbles, the uniform diffusion of some components of the disinfectant will be hindered, which may lead to too low concentration in some areas and unstable disinfection effect of the disinfectant. Summary of the Invention

[0005] The purpose of the present invention is to provide a disinfectant preparation device to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention relates to a disinfectant preparation device, including a tank body, on the top of which a sealing cover is installed. A mixing unit is fixedly connected to the top of the sealing cover. On one side of the sealing cover close to the center of the circle, two sealing discs are slidably connected; on the side of the sealing disc away from the sealing cover, a support disc is fixedly connected to each. The support disc is rotationally connected to the stirring unit;

[0008] The stirring unit includes a double-headed motor, which is fixedly connected to the upper support plate. The output end at the bottom of the double-headed motor is fixedly connected to a connecting block; the connecting block and the support plate are both rotationally connected. A screw conveyor is fixedly connected to the bottom of the connecting block; the screw conveyor stirs downward. Suspension blocks are fixedly connected between adjacent blades of the screw conveyor; elastic members are fixedly connected to the adjacent sides of the suspension blocks. One end of the elastic member away from the suspension block is fixedly connected to a counterweight block. A defoaming needle is fixedly connected to the middle of the counterweight block. The elastic member, the defoaming needle and the counterweight block are all made of corrosion-resistant materials.

[0009] Further, the stirring unit further includes a sun gear, which is fixedly connected to the connecting block. The sun gear meshes with three planetary gears, and the planetary gears mesh with a gear ring. The gear ring is fixedly connected to the inner wall of the sealing cover; a stirring rod is fixedly connected to the middle of each planetary gear. The stirring rod is fixedly connected to the lower sealing disc.

[0010] Further, spiral blades are fixedly connected to the outer wall of the stirring rod. The spiral blades stir upward. Suspension blocks, elastic members, counterweight blocks and defoaming needles are arranged in an array between adjacent spiral blades.

[0011] Further, the output end at the top of the double-headed motor is fixedly connected to a rotating disc. Three connecting rods are fixedly connected to the bottom of the rotating disc; the connecting rods are fixedly connected to the planetary gears and the sealing discs respectively.

[0012] Further, the mixing unit includes a water tank, the bottom of which is fixedly connected to the sealing cover. A sealing ring is rotationally connected to one side of the water tank close to the center of the circle; three through holes are opened on the surface of the sealing ring, and a water delivery pipe is fixedly connected to each through hole; the water delivery pipe is fixedly connected to the stirring rod; the inside of the stirring rod is hollow, and the stirring rod, the water delivery pipe and the water tank are all communicated;

[0013] A water outlet is opened on one side of the stirring rod close to the spiral blade. Atomizing spray heads are fixedly connected to the upper and lower surfaces of the spiral blade.

[0014] Further, an ultrasonic module is fixedly connected to the bottom of the tank body. The top of the ultrasonic module is rotationally connected to the screw conveyor and slidably connected to the stirring rod.

[0015] Furthermore, a plurality of flow disturbing blocks are randomly arranged on the surface of the auger, and the flow disturbing blocks are used to disturb the water flow.

[0016] Furthermore, the surfaces of the tank body, the stirring rod, the spiral blade and the auger are all covered with a polytetrafluoroethylene coating.

[0017] The present invention has the following beneficial effects:

[0018] 1. When the present invention is stirring, it can not only increase the stirring efficiency of the disinfectant solution, but also reduce the generation of bubbles. And since the disinfectant solution will spread around when it contacts the bottom, it can also reduce the stirring dead angle, so that the disinfectant solution is mixed more evenly; when the auger rotates, the defoaming needle will shift outward due to the centrifugal force of the counterweight. Since the surface area of the counterweight is relatively large, it will swing up and down when contacting the water flow. When the defoaming needle swings up and down, it can pierce the bubbles.

[0019] 2. The atomizing water spray head of the present invention will cover a water film on the spiral blade, which can not only drive the flow of the disinfectant solution, but also prevent the corrosive disinfectant solution from corroding the spiral blade; when the atomizing water spray head sprays out, it will make the components after partial volatilization of the disinfectant solution fuse with water and remix with the water, thereby reducing the volatilization of the disinfectant solution, avoiding the corrosion of the metal components by the volatilized chlorine gas, and preventing the increase of the air pressure in the tank body due to the volatilization of the disinfectant solution.

[0020] 3. When the demand for the disinfectant solution is small, the present invention can utilize the cavitation effect of ultrasonic waves for mixing and defoaming. While eliminating the bubbles, it will also mix the disinfectant solution. Thus, not only the bubbles are eliminated, but also the disinfectant solution is mixed; and when the ultrasonic waves contact the defoaming needle, it will make the defoaming needle vibrate more violently, so that the defoaming efficiency of the defoaming needle is higher and the effect is better.

Detailed implementation manners

[0033] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-9 As shown, the present invention is a disinfectant preparation device, including a tank body 1, a sealing cover 11 is installed on the top of the tank body 1, a mixing unit 3 is fixedly connected to the top of the sealing cover 11, and two sealing disks 13 are slidably connected to a side of the sealing cover 11 close to the center of the circle; support disks 14 are fixedly connected to sides of the sealing disks 13 away from the sealing cover 11, and the support disks 14 are rotationally connected to a stirring unit 2;

[0035] The stirring unit 2 includes a double-headed motor, which is fixedly connected to the support plate near the upper part. The output end at the bottom of the double-headed motor is fixedly connected with a connecting block 211; the connecting block 211 and the support plate are both rotatably connected, and a screw conveyor 22 is fixedly connected to the bottom of the connecting block 211; the screw conveyor 22 stirs downward, and suspension blocks 223 are fixedly connected between adjacent blades of the screw conveyor 22; elastic members 224 are fixedly connected to the sides of the suspension blocks 223 close to each other, and a counterweight block 225 is fixedly connected to the end of the elastic member 224 away from the suspension block 223. A defoaming needle 222 is fixedly connected to the middle of the counterweight block 225; the elastic members 224, the defoaming needles 222 and the counterweight blocks 225 are all made of corrosion-resistant materials.

[0036] In this embodiment, considering that solid substances such as sodium hypochlorite are added when preparing the disinfectant solution, it is usually necessary to stir the disinfectant solution to accelerate the mixing of the disinfectant solution; in the prior art, an impeller is usually used to rotate in the disinfectant solution when stirring. The stirring area of using an impeller for stirring is small, and there may be some dead corners that cannot be stirred, resulting in uneven diffusion of some components of the disinfectant solution; when stirring, cavities may be generated in the disinfectant solution due to the high shear force of the impeller, and a large amount of the disinfectant solution may come into contact with air, resulting in the generation of bubbles. Since the presence of bubbles will hinder the uniform diffusion of some components of the disinfectant solution, it may lead to too low concentration in some areas, resulting in unstable disinfection effect of the disinfectant solution.

[0037] When mixing the disinfectant solution, by starting the output shaft at the bottom of the double-headed motor, the connecting block 211 can be driven to rotate. When the connecting block 211 rotates, the screw conveyor 22 will rotate. Since the screw conveyor 22 stirs downward, when stirring, the disinfectant solution will move downward following the rotation of the screw conveyor 22. When the disinfectant solution contacts the bottom of the tank 1, it will spread around, and since the disinfectant solution at the bottom of the tank 1 increases, it will squeeze the excess disinfectant solution to move upward. Since the liquid flow pushed by the screw conveyor 22 is relatively slow, the liquid level of the disinfectant solution will not turn over at this time, but will generate slight fluctuations. Thus, not only can the stirring efficiency of the disinfectant solution be increased, but also the generation of bubbles can be reduced. And since the disinfectant solution contacts the bottom and spreads around, the stirring dead corners can also be reduced, so that the disinfectant solution is mixed more evenly.

[0038] Since solid substances such as sodium hypochlorite or chlorine-containing effervescent tablets are usually added when mixing the disinfectant solution, after adding the effervescent tablets, not only will bubbles be generated independently, but also the bubbles in the stirred disinfectant solution may increase; when the screw conveyor 22 does not rotate, the defoaming needles 222 will be suspended between the blades of the screw conveyor 22 through the counterweight blocks 225 and the elastic members 224. Since they are retracted between the blades of the screw conveyor 22, it can provide a larger space for the tank 1 during maintenance or cleaning, making it more convenient to operate.

[0039] When the auger 22 rotates, the defoaming needle 222 will shift outwards due to the centrifugal force of the counterweight 225. Since the surface area of the counterweight 225 is relatively large, it will swing up and down when contacting the water flow. When the defoaming needle 222 swings up and down, it can pierce the bubbles; when the defoaming needle 222 swings up and down, it will also pierce the chlorine-containing effervescent tablets. After the chlorine-containing effervescent tablets are pierced, the contact area with water will increase, and the content effervescent tablets will dissolve faster; since the counterweight 225 also causes the defoaming needle 222 to swing back and forth when contacting the water flow, when combined with the back-and-forth swing, the range where the bubbles can be pierced can be wider, and the bubbles can be further reduced, and the jitter of the defoaming needle 222 can also defoam; and the air pressure generated by the rapid rotation of the auger 22 driving the defoaming needle 222 can be used to cut the bubbles. Since the shear force of the defoaming needle 222 is low and the surface area is small, no bubbles will be generated due to excessive shear force when cutting the bubbles, thereby reducing the generation of bubbles.

[0040] Specifically, the stirring unit 2 further includes a sun gear 23, the sun gear 23 is fixedly connected to the connecting block 211, and the sun gear 23 meshes with three planetary gears 24; the planetary gears 24 mesh with a gear ring 25, and the gear ring 25 is fixedly connected to the inner wall of the sealing cover 11; the middle parts of the planetary gears 24 are all fixedly connected with stirring rods 26, and the stirring rods 26 are fixedly connected to the sealing disk 13 near the lower part.

[0041] In this embodiment, considering that when applied to the scenario of mass production, the efficiency of stirring only by one auger 22 is relatively low, and if the rotation speed of the auger 22 is too fast, it will also cause cavities to be cut out of the disinfectant, resulting in an increase in the bubbles of the disinfectant and affecting the disinfection effect of the finished disinfectant;

[0042] During stirring, the rotation of the connecting block 211 can drive the sun gear 23 to rotate, and the rotation of the sun gear 23 can drive the three planetary gears 24 to revolve around the sun gear 23. Since the three planetary gears 24 are all meshed with the gear ring 25, and the gear ring 25 is fixed to the inner wall of the sealing cover 11, at this time, the planetary gears 24 will drive the stirring rods 26 to revolve around the sun gear 23. When the stirring rods 26 move, the disinfectant in the tank body 1 will rotate. When the rotation speed reaches a certain level, the disinfectant will generate a vortex, and cooperate with the auger 22 to drive the disinfectant downward, thereby making the mixing speed of the disinfectant faster, increasing the mixing efficiency, and further reducing the dead corners that cannot be stirred through the setting of the stirring rods 26.

[0043] Specifically, a spiral blade 34 is fixedly connected to the outer wall of the stirring rod 26. The spiral blade 34 stirs upwards, and suspension blocks 223, elastic members 224, counterweights 225 and defoaming needles 222 are arranged in an array between adjacent spiral blades 34.

[0044] In this embodiment, considering that when the stirring rod 26 stirs the disinfectant solution, it may cause some disinfectant solution to move along with the stirring rod 26, resulting in the inability of the disinfectant solution at the bottom and top of the tank body 1 to be normally exchanged, which may cause uneven stirring of the disinfectant solution and thus affect the disinfection effect of the disinfectant solution;

[0045] During stirring, since the planetary gear 24 rotates around the sun gear 23 while driving the stirring rod 26 to revolve, it will also rotate itself at the same time. When the stirring rod 26 rotates, the spiral blade 34 will rotate, and the disinfectant solution will move upward along with the spiral blade 34. At this time, when the disinfectant solution is pushed to the bottom by the auger 22, it will return to the top through the spiral blade 34. During this process, due to multiple rotations of the auger 22 and the spiral blade 34, the disinfectant solution will be evenly mixed, and the disinfectant solution can flow to avoid corrosion caused by the long-term contact of the disinfectant solution with the tank body 1;

[0046] Through the settings of the suspension block 223, the elastic member 224, the counterweight 225 and the defoaming needle 222, the defoaming range can be made wider and the defoaming efficiency can be increased.

[0047] Specifically, the output end at the top of the double-headed motor is fixedly connected with a rotating disk 12, and three connecting rods 122 are fixedly connected to the bottom of the rotating disk 12; the connecting rods 122 and the planetary gear 24 are fixedly connected, and the connecting rods 122 and the sealing disk 13 are fixedly connected.

[0048] In this embodiment, considering that when the spiral blade 34 drives the disinfectant solution to move upward, it is inevitable to contact the air, and considering that some disinfectant solution will generate bubbles when contacting the air during stirring. If a large number of bubbles are generated, it will hinder the uniform diffusion of some components of the disinfectant solution and cause too low concentration in some parts, thus affecting the disinfection effect of the disinfectant solution;

[0049] When stirring the disinfectant solution that is prone to generating bubbles, by starting the output end at the top of the double-headed motor, it can drive the rotating disk 12 to rotate. When the rotating disk 12 rotates, it will drive the connecting rod 122 to move. Since the connecting rod 122 is fixedly connected with the sealing disk 13, and the sealing disk 13 is fixedly connected with the stirring rod 26, when the connecting rod 122 drives the sealing disk 13 to rotate, it will pull the stirring rod 26 to move and at the same time make the planetary gear 24 rotate. When the planetary gear 24 rotates, it will drive the sun gear 23 to rotate. At this time, the sun gear 23, as a driven part, will accelerate, thus improving the stirring efficiency of the auger 22. Since the auger 22 transfers the disinfectant solution to the bottom of the storage tank, fewer bubbles will be generated at this time, and at this time the rotational speed of the planetary gear 24 will decrease, and the amount of disinfectant solution transferred upward by the spiral blade 34 will also decrease, thereby reducing the generation of bubbles.

[0050] Specifically, the mixing unit 3 includes a water tank 31. The bottom of the water tank 31 is fixedly connected to the sealing cover 11. One side of the water tank 31 close to the center of the circle is rotatably connected with a sealing ring 32. Three through holes are formed on the surface of the sealing ring 32, and a water delivery pipe 33 is fixedly connected in each through hole. The water delivery pipe 33 and the stirring rod 26 are both fixedly connected. The inside of the stirring rod 26 is hollow, and the stirring rod 26, the water delivery pipe 33 and the water tank 31 are all communicated with each other.

[0051] One side of the stirring rod 26 close to the spiral blade 34 is provided with a water outlet 261. Atomizing spray heads 35 are fixedly connected to both the upper and lower surfaces of the spiral blade 34.

[0052] In this embodiment, considering that some components of the disinfectant have certain volatility, such as alcohol or chlorine, when preparing the disinfectant, stirring will cause the disinfectant to volatilize faster. When the components of the disinfectant volatilize, the air pressure inside the tank body 1 will increase. If the tank body 1 is made of plastic, it may explode due to being unable to withstand the pressure. At the same time, when flammable substances encounter an open flame, it may also cause an explosion.

[0053] While the spiral blade 34 stirs the disinfectant, the water in the water tank 31 will enter the inside of the stirring rod 26 through the water delivery pipe 33. When the water enters the stirring rod 26, it will enter the atomizing spray heads 35 on the spiral blade 34 through the water outlet 261. When the water enters the atomizing spray heads 35, atomized water will be sprayed outwards. At this time, the atomized water will cover a water film on the spiral blade 34, which can not only drive the flow of the disinfectant, but also prevent the corrosive disinfectant from corroding the spiral blade 34.

[0054] After the atomizing spray heads 35 spray out, the volatilized components of the disinfectant will be fused with the water and re-mixed with the water. Thus, the volatilization of the disinfectant can be reduced, the corrosion of the metal parts caused by the volatilized chlorine can be avoided, and at the same time, the increase of the air pressure inside the tank body 1 caused by the volatilization of some components of the disinfectant can be prevented.

[0055] Through the setting of the sealing ring 32, when the water delivery pipe 33 rotates following the stirring rod 26, the water delivery pipe 33 will drive the sealing ring 32 to rotate at the same time, so the water tank 31 remains sealed.

[0056] Specifically, an ultrasonic module 4 is fixedly connected to the bottom of the tank body 1. The top of the ultrasonic module 4 is rotatably connected to the auger 22, and the top of the ultrasonic module 4 is slidably connected to the stirring rod 26.

[0057] In this embodiment, considering that bubbles are inevitably generated during stirring, the effect of the disinfectant will decrease after the bubbles are generated; and when applied to scenarios such as laboratories, a large amount of disinfectant is required for large-scale cleaning, while only a small amount of disinfectant is needed for daily use. However, if a small amount of disinfectant is mixed by the auger 22, etc., a large amount of the disinfectant will be mixed with air, resulting in an increase in bubbles.

[0058] When applied to scenarios with less demand for disinfectant, the bidirectional motor 21 can be turned off, and only the ultrasonic module 4 is used for mixing. When the ultrasonic module 4 is started, it will produce a cavitation effect on the disinfectant. At this time, the ultrasonic waves will first cause the disinfectant to generate tiny bubbles, and after continuously generating ultrasonic waves, the tiny bubbles will burst. At the same time, the bubbles in the disinfectant itself can also be broken. Thus, a certain fluctuation can be generated in the disinfectant, that is, the disinfectant is vibrated. At this time, the bubbles in the disinfectant will be eliminated through the cavitation effect and vibration. While eliminating the bubbles, the disinfectant will also be mixed through vibration. Thus, not only can the bubbles be eliminated, but the disinfectant can also be mixed. When only a small amount of disinfectant is needed, only the ultrasonic waves can be used to defoam and mix the disinfectant, which can reduce energy consumption, make the equipment more energy-saving and environmentally friendly, and thus enable non-production enterprises to use it.

[0059] When the demand for disinfectant is large, the stirring unit 2 and the ultrasonic module 4 can be operated simultaneously. Thus, not only can the stirring efficiency be higher, but defoaming can also be carried out during stirring, which can reduce the use of defoamers and reduce production costs; and when the ultrasonic waves come into contact with the defoaming needle 222, the defoaming needle 222 will vibrate more violently, making the defoaming needle 222 pierce the bubbles more frequently, so that the defoaming efficiency of the defoaming needle 222 is higher and the effect is better.

[0060] Specifically, a plurality of spoiler blocks 221 are randomly arranged on the surface of the auger 22, and the spoiler blocks 221 are used to disrupt the water flow.

[0061] In this embodiment, through the setting of the spoiler blocks 221, the disinfectant can flow irregularly during the stirring process of the auger 22. Compared with directly using the auger 22, the water flow can be changed into a turbulent flow, which can make the disinfectant mix more frequently and more evenly, avoiding uneven disinfection effects of the mixed disinfectant. At the same time, after the solids enter, the solids can continue to float by disrupting the water flow and can be fused with the disinfectant faster; when the spoiler blocks 221 disrupt the water flow, the defoaming needle 222 will be driven by the turbulent water flow and generate irregular vibrations, which can make the defoaming effect of the defoaming needle 222 better and the efficiency higher.

[0062] Specifically, the tank body 1, the stirring rod 26, the spiral blades 34 and the auger 22 are all made of stainless steel material, and the surfaces are all covered with a polytetrafluoroethylene coating.

[0063] In this embodiment, considering that some components of the disinfectant may be corrosive, such as chlorine gas, which has strong corrosivity to metals, the metal components will be accelerated in aging after long-term contact with chlorine gas, thus increasing the equipment usage cost.

[0064] Since stainless steel has good corrosion resistance, corrosion can be reduced during use. At the same time, by covering the polytetrafluoroethylene coating, the corrosion of metal components can be further reduced.

[0065] During use,

[0066] First of all, when mixing the disinfectant, by starting the output shaft at the bottom of the double-headed motor, the connecting block 211 can be driven to rotate. When the connecting block 211 rotates, the auger 22 will rotate. Since the auger 22 stirs downward, the disinfectant will move downward along with the rotation of the auger 22 during stirring. When the disinfectant touches the bottom of the tank body 1, it will spread around. And because the disinfectant at the bottom of the tank body 1 increases, it will squeeze the excess disinfectant to move upward. Since the liquid flow pushed by the auger 22 is relatively slow, the liquid level of the disinfectant will not turn over at this time, but will generate slight fluctuations. Thus, not only can the stirring efficiency of the disinfectant be increased, but also the generation of bubbles can be reduced. And because the disinfectant touches the bottom and spreads around, the stirring dead angle can also be reduced, so that the disinfectant is mixed more evenly.

[0067] When stirring the disinfectant that is prone to generate bubbles, by starting the output end at the top of the double-headed motor, the rotating disk 12 can be driven to rotate. When the rotating disk 12 rotates, it will drive the connecting rod 122 to move. Since the connecting rod 122 is fixedly connected to the sealing disk 13, and the sealing disk 13 is fixedly connected to the stirring rod 26, when the connecting rod 122 drives the sealing disk 13 to rotate, it will pull the stirring rod 26 to move and at the same time make the planetary gear 24 rotate. When the planetary gear 24 rotates, it will drive the sun gear 23 to rotate. At this time, the sun gear 23, as a driven part, will accelerate, thus improving the stirring efficiency of the auger 22. Since the auger 22 will transfer the disinfectant to the bottom of the storage tank, fewer bubbles will be generated at this time. And at this time, the rotation speed of the planetary gear 24 will decrease, and the disinfectant transferred upward by the spiral blades 34 will also be reduced. Thus, the generation of bubbles can be reduced.

[0068] Since solid substances, such as sodium hypochlorite or chlorine-containing effervescent tablets, are usually added when disinfectant solutions are mixed, after the chlorine-containing effervescent tablets are added, not only will bubbles be generated autonomously, but it may also increase the bubbles in the stirred disinfectant solution; when the auger 22 is not rotating, the defoaming needle 222 will hang between the blades of the auger 22 through the counterweight 225 and the elastic member 224. Since it is retracted between the blades of the auger 22, it can provide more space for the tank body 1 during maintenance or cleaning, making it more convenient to operate;

[0069] When the auger 22 rotates, the defoaming needle 222 will shift outwards due to the centrifugal force of the counterweight 225. Since the surface area of the counterweight 225 is relatively large, when it comes into contact with the water flow, it will cause itself to swing up and down. When the defoaming needle 222 swings up and down, it can pierce the bubbles; when the defoaming needle 222 swings up and down, it will also pierce the chlorine-containing effervescent tablets. After the chlorine-containing effervescent tablets are pierced, the contact area with water will increase, and the chlorine-containing effervescent tablets will dissolve faster; since the counterweight 225 will also cause the defoaming needle 222 to swing back and forth when it comes into contact with the water flow, when combined with the back-and-forth swing, the range where bubbles can be pierced can be wider, which can further reduce bubbles, and the jitter of the defoaming needle 222 can also defoam; and the air pressure generated by the rapid rotation of the auger 22 driving the defoaming needle 222 can be used to cut the bubbles. Since the shearing force of the defoaming needle 222 is relatively low and the surface area is small, no bubbles will be generated due to excessive shearing force when cutting the bubbles, thereby reducing the generation of bubbles;

[0070] Through the setting of the spoiler block 221, the disinfectant solution can be made to flow irregularly during the stirring process of the auger 22. Compared with directly using the auger 22, the water flow can be changed into a turbulent flow, thereby making the mixing of the disinfectant solution more frequent and the mixing of the disinfectant solution more uniform, avoiding the occurrence of uneven disinfection effects of the mixed disinfectant solution. At the same time, when the solid substances enter, the solid substances can be continuously floated by disturbing the water flow and can be fused with the disinfectant solution faster; when the spoiler block 221 disturbs the water flow, the defoaming needle 222 will be driven by the turbulent water flow and generate irregular jitter, which can make the defoaming effect of the defoaming needle 222 better and the efficiency higher.

[0071] Secondly, during stirring, the rotation of the connecting block 211 can drive the sun gear 23 to rotate, and the rotation of the sun gear 23 can drive the three planetary gears 24 to revolve around the sun gear 23. Since the three planetary gears 24 are all meshed with the gear ring 25, and the gear ring 25 is fixed on the inner wall of the sealing cover 11, at this time, the planetary gears 24 will drive the stirring rod 26 to revolve around the sun gear 23. When the stirring rod 26 moves, the disinfectant liquid will rotate in the tank body 1. When the rotation speed reaches a certain level, the disinfectant liquid will generate a vortex, and cooperate with the auger 22 to drive the disinfectant liquid downward. Thus, the mixing speed of the disinfectant liquid can be made faster, the mixing efficiency can be increased, and the dead angle that cannot be stirred can be further reduced through the setting of the stirring rod 26;

[0072] Since the planetary gear 24 will also rotate itself while driving the stirring rod 26 to revolve around the sun gear 23, when the stirring rod 26 rotates, the spiral blade 34 will rotate, and the disinfectant liquid will move upward along with the spiral blade 34. At this time, when the disinfectant liquid is pushed to the bottom by the auger 22, it will return to the top through the spiral blade 34. During this process, due to multiple rotations of the auger 22 and the spiral blade 34, the disinfectant liquid can be mixed evenly, and the disinfectant liquid can flow to avoid corrosion caused by the long-term contact between the disinfectant liquid and the tank body 1.

[0073] Meanwhile, when the spiral blade 34 stirs the disinfectant liquid, the water in the water tank 31 will enter the inside of the stirring rod 26 through the water delivery pipe 33. When the water enters the stirring rod 26, it will enter the atomizing spray head 35 on the spiral blade 34 through the water outlet 261. When the water enters the atomizing spray head 35, atomized water will be sprayed outwards. At this time, the atomized water will cover a water film on the spiral blade 34, which can not only drive the flow of the disinfectant liquid, but also prevent the corrosive disinfectant liquid from corroding the spiral blade 34;

[0074] After the atomizing spray head 35 sprays out, the components after partial volatilization of the disinfectant liquid will be fused with the water and remixed with the water. Thus, the volatilization of the disinfectant liquid can be reduced, the corrosion of the metal components caused by the volatilized chlorine gas can be avoided, and at the same time, the increase in the air pressure inside the tank body 1 caused by the partial volatilization of the components of the disinfectant liquid can be prevented;

[0075] Through the setting of the sealing ring 32, when the water delivery pipe 33 rotates following the stirring rod 26, the water delivery pipe 33 will drive the sealing ring 32 to rotate at the same time, so the water tank 31 remains sealed.

[0076] Finally, when applied to scenarios with less demand for disinfectant solution, the bidirectional motor 21 can be turned off and only the ultrasonic module 4 is used for mixing. When the ultrasonic module 4 is started, it will produce a cavitation effect on the disinfectant solution. At this time, the ultrasonic waves will first cause tiny bubbles to form in the disinfectant solution, and after continuous generation of ultrasonic waves, the tiny bubbles will burst. As a result, certain fluctuations, that is, vibrations, will be generated in the disinfectant solution. At this time, the bubbles in the disinfectant solution will be eliminated through the cavitation effect and vibrations. While eliminating the bubbles, the disinfectant solution will also be mixed. Thus, not only can the bubbles be eliminated, but the disinfectant solution can also be mixed; when only a small amount of disinfectant solution is needed, only the ultrasonic waves can be used to defoam and mix the disinfectant solution, thereby reducing energy consumption, so that non-production enterprises can also use it;

[0077] When there is a large demand for disinfectant solution, the stirring unit 2 and the ultrasonic module 4 can be operated simultaneously. Thus, not only can the stirring efficiency be higher, but defoaming can also be carried out during stirring, reducing the use of defoaming agents and production costs; moreover, when the ultrasonic waves come into contact with the defoaming needle 222, the defoaming needle 222 will vibrate more violently, causing the defoaming needle 222 to pierce the bubbles more frequently, so that the defoaming efficiency of the defoaming needle 222 is higher and the effect is better.
