Description

Technical Field

[0001] This invention belongs to the field of disinfectants, specifically a preparation process for a spray-type disinfectant. Background Technology

[0002] Disinfectants are used in fields such as medical care, hygiene, and food safety. For example, spray disinfectants are frequently used for home disinfection, epidemic prevention and control, and medical device disinfection.

[0003] Chinese patent CN111544450A discloses a fruit-scented and color-coated no-rinse spray disinfectant and its preparation method. The fruit-scented and color-coated no-rinse spray disinfectant comprises the following raw materials in parts by weight: 140-160 parts of 75% vol alcohol, 20-30 parts of edible fruit flavoring, 20-30 parts of food coloring, 50-60 parts of glycerin, 15-25 parts of lactic acid, 10-15 parts of bactericidal synergist A, 7-13 parts of bactericidal synergist B, and 60-80 parts of distilled water. In this invention, ultrasound can enhance the molecular activation energy of methanol, n-propanol, isoamyl alcohol, acids, esters, and other substances in 75% vol alcohol, increasing the probability of intermolecular collisions and accelerating esterification, condensation, and redox reactions. This results in an increased ester content in the alcohol disinfectant, making the aroma more intense and improving the user experience.

[0004] While this disinfectant has a disinfecting effect and can improve the user experience, its composition is too complex. The excessive proportion of raw materials makes the preparation of the disinfectant more difficult and increases production costs accordingly.

[0005] Therefore, the present invention provides a spray-type disinfectant and its preparation process. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The spray-type disinfectant of the present invention is composed of the following raw materials in parts by weight: 5-6 parts of benzalkonium chloride; 0.5-0.8 parts of fatty alcohol polyoxyethylene ether; Eucalyptus oil 1-1.5 parts; 92-95 parts purified water; The benzalkonium chloride is of pharmaceutical grade; The fatty alcohol polyoxyethylene ether is chemically pure; The eucalyptus oil is of food grade. Preferably, the spray-type disinfectant is prepared by the following steps: S1. Add purified water, fatty alcohol polyoxyethylene ether and eucalyptus oil to the emulsification kettle in sequence, stir for 65-75 minutes to obtain emulsion; S2. Add benzalkonium chloride to the emulsion and continue stirring for 35-45 minutes to obtain a surface disinfectant solution. S3. Dilute the surface disinfectant with water at a ratio of 1:30 to obtain a spray-type disinfectant.

[0008] Preferably, the emulsification vessel used in the preparation of the spray-type disinfectant includes a vessel body. A power shaft is rotatably mounted inside the vessel body, and a stirring blade is mounted on the power shaft. Multiple movable plates are movably inserted into the sides of the stirring blades, and reset components are mounted on the movable plates. Protective pads are mounted on the outer sides of the movable plates. A detection component that cooperates with the movable plates is installed inside the stirring blades. During operation, the protective pads are made of a stretchable and deformable flexible material, sealing the movable plates and stirring blades to prevent emulsion from entering the stirring blades. When the stirring blades stir the emulsion, the movable plates are squeezed by the liquid and move. In the initial stage of stirring, the emulsion is not yet formed, and the composition inside the vessel body is uneven. The objects touched by the stirring blades include solids, liquids, and emulsions, so the forces on each movable plate are uneven, and the movement amplitude is also different. At this time, the movable plates cannot trigger the detection component simultaneously. When the emulsion is stirred evenly, the force exerted by the emulsion on the movable plates is uniform. At this time, the detection component is triggered by the movable plate, indicating that the emulsion has been stirred evenly. This achieves the function of real-time monitoring of the emulsion stirring effect during the preparation of the spray-type disinfectant.

[0009] Preferably, the detection assembly includes a detection plate slidably installed inside the stirring blade. The stirring blade has a mating groove corresponding to the movable plate. A rod is fixedly installed on the movable plate, inserting into the mating groove. A retaining plate is movably inserted into the mating groove inside the detection plate, with a support spring installed on the retaining plate. A middle block is movably inserted into the mating groove, located between the rod and the retaining plate. During operation, in the initial stirring stage, the material distribution inside the vessel is uneven. During the rotation of the stirring blade, the compressive force on each movable plate varies, some being too large and others too small. The movement range of each movable plate differs, resulting in different compression ranges for the retaining plate. The movable plate with greater force moves more, causing both the retaining plate and the middle block to be squeezed into the groove. The movable plate with less force moves too little, leaving the retaining plate stuck in the mating groove. Due to the uneven force on the movable plates, not all retaining plates can be squeezed out of the mating groove simultaneously, and since the middle blocks are all located within the mating groove, the detection plate will not move. In the later stage of stirring, after the emulsion is evenly stirred, the squeezing pressure on the moving plate becomes uniform and reaches a balanced state. At this time, all the clamping plates are squeezed to separate from the mating tank, and the middle block is located in the mating tank. Therefore, the detection plate can move outward under the action of centrifugal force. By monitoring the state of the detection plate, it can be determined that the emulsion has been evenly stirred. In addition, the subsequent stirring speed and stirring time can be adjusted based on this judgment. This improves the problem that when preparing disinfectant, if the emulsion being stirred is not monitored in real time, it is easy to have insufficient or excessive stirring of the emulsion, which affects the quality of the emulsion. Preferably, a tension spring is installed on the detection plate, a sensor is installed inside the stirring blade, and a T-shaped contact rod corresponding to the sensor is provided on the detection plate. During operation, a control unit is installed inside the vessel to control the stirring operation. The sensor is electrically connected to the control unit. The sensor can be a pressure sensor. In the initial state, the T-shaped contact rod is separated from the sensor. After the emulsion is stirred evenly and the detection plate moves under the action of centrifugal force, the T-shaped contact rod contacts the sensor, and the sensor sends a signal to the control unit. When the control unit receives the signal, it can determine that the emulsion has been stirred evenly.

[0010] Preferably, the reset assembly includes a sleeve fixedly installed on the inner wall of the movable plate, the sleeve movably sleeved on the outside of the insert rod, a compression spring one installed on the sleeve, a compression spring two installed on the insert rod, a conical plate fixedly installed on the outside of the insert rod, a baffle plate movably inserted into the inside of the stirring blade to block the conical plate, a reset spring installed on the baffle plate, a pressure rod fixedly installed on the sleeve, a wedge block provided on the pressure rod, and a through hole corresponding to the wedge block opened in the baffle plate; during operation, in the initial stage of stirring, the material distribution in the reactor is uneven, and the movement of the movable plate is in a state of change, which may cause the intermediate block and the clamping plate to be temporarily in a state of equilibrium. By setting the sleeve, compression spring one, compression spring two, and baffle plate, the insert rod will only move after the movable plate has moved for a period of time. There is a time difference between the movement of the insert rod and the movement of the movable plate. This time difference can further reduce the possibility that all the clamping plates and intermediate blocks are in a temporary state of equilibrium at the same time when the emulsion is not stirred evenly, and improve the situation where the movement state of the movable plate is constantly changing in the initial stage of stirring, which may lead to all the clamping plates and intermediate blocks being in a temporary state of equilibrium at the same time, resulting in misjudgment.

[0011] Preferably, a boss is fixedly installed on the inner wall of the movable plate, and the boss is fixedly connected to the sleeve. The boss is located on the outside of the insertion rod. During operation, by setting the boss, space is left for the insertion rod. In the initial stage of the movable plate movement, the movable plate drives the sleeve to move through the boss. The movable plate will not directly contact the insertion rod, which improves the situation where the movable plate may accidentally hit the insertion rod.

[0012] Preferably, the stirring blade has a detection hole, a chain is movably installed inside the detection hole, a return torsion spring is provided on the mounting shaft of the chain, a friction belt is provided on the outer side of the chain, a one-way rotating plate is fixedly installed on the side of the chain away from the detection hole, and a switch group corresponding to the one-way rotating plate is installed inside the stirring blade. During operation, in the initial stage of stirring, when the emulsion has not yet formed, the emulsion has poor fluidity. When the emulsion flows, it generates a large frictional force on the friction belt, causing the friction belt to rotate a large amplitude, and the one-way rotating plate to move down a large amplitude. At this time, after the one-way rotating plate moves down, it contacts the switch below, the switch below is triggered, and a signal is sent to the control unit. Then the friction belt moves back, the one-way rotating plate resets and contacts the switch above, the switch above is triggered, and a signal is sent to the control unit. Therefore, the control unit will receive two signals in a short period of time. After mixing is complete and the emulsion is formed, the emulsion has good fluidity. When the emulsion flows, the friction force generated on the friction belt is small, the rotation amplitude of the friction belt is small, and the downward movement of the one-way rotating plate is small. At this time, after the one-way rotating plate moves down, it will not contact the switch below. The switch below is not triggered and no signal is sent. Then the friction belt moves back, the one-way rotating plate resets and contacts the switch above. The switch above is triggered and sends a signal to the control unit. Therefore, the control unit will receive a signal once in a short time. Therefore, by counting the number of signals received in a short period of time, the control unit can determine whether the emulsion's fluidity is up to standard, thus realizing the function of real-time monitoring of the emulsion's fluidity during the preparation of disinfectant.

[0013] Preferably, the stirring blade has a through groove inside, a rotating shaft is rotatably installed inside the through groove, an impeller is installed on the rotating shaft, a sealing plate that blocks the detection hole is movably installed on the top of the stirring blade, a driven plate is provided on the sealing plate, a disc is fixedly installed on the top of the rotating shaft above the stirring blade, a ramp plate corresponding to the driven plate is fixedly installed on the top of the disc, and a protective cover is fixedly installed on the top of the stirring blade, covering the outside of the disc and the sealing plate; during operation, in the initial state, the sealing plate is located at the bottom of its moving position under the action of gravity, or a return spring can be installed on the sealing plate, at which time the sealing plate blocks the detection hole, and the emulsion will not flow into the detection hole; The channel is always open. When the stirring blades rotate, the emulsion flows through the channel and drives the rotating shaft and disc to rotate via the impeller. During the rotation of the disc, when the inclined plate comes into contact with the driven plate, it will squeeze the sealing plate to move upward, causing the sealing plate to be misaligned with the detection hole. After the inclined plate and the driven plate are misaligned, the sealing plate moves downward again under the action of gravity and blocks the detection hole. In this way, the function of intermittently opening and closing the detection hole is realized, so as to monitor the flowability of the emulsion in real time. This process does not require an additional electric drive mechanism, reducing costs, and is simple in structure and easy to use.

[0014] Preferably, a drive motor for driving the power shaft is installed on the vessel body; during operation, the drive motor is electrically connected to a control unit inside the vessel body, and the control unit controls the start of the drive motor. Alternatively, a reduction gearbox can be installed on the drive motor to adjust and control the speed of the power shaft. The beneficial effects of this invention are as follows: 1. The spray-type disinfectant of the present invention uses benzalkonium chloride as the main disinfectant and bactericidal component, combined with eucalyptus oil, which can achieve a good disinfection and bactericidal effect. The composition is simple, which improves the problem of excessive components in disinfectants, which leads to increased preparation difficulty and production costs. Furthermore, the purification of water, fatty alcohol polyoxyethylene ether and eucalyptus oil is first made into an emulsion, and then benzalkonium chloride is mixed into it, which helps to improve the stability of the disinfectant and facilitates storage and use.

[0015] 2. The spray-type disinfectant of this invention involves stirring an emulsion during preparation. Initially, the emulsion is not yet formed, the composition inside the vessel is uneven, and the stirring blades come into contact with solids, liquids, and emulsions. Consequently, the forces on the moving plates are uneven, and their movement amplitudes differ. At this stage, the moving plates cannot simultaneously trigger the detection component. When the emulsion is stirred evenly, the force exerted on the moving plates by the emulsion is uniform. At this point, the detection component is triggered by the moving plates, indicating that the emulsion has been stirred evenly. This achieves the function of real-time monitoring of the emulsion stirring effect during the preparation of the spray-type disinfectant. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] The spray-type disinfectant of the present invention is composed of the following raw materials in parts by weight: 5-6 parts of benzalkonium chloride; 0.5-0.8 parts of fatty alcohol polyoxyethylene ether; Eucalyptus oil 1-1.5 parts; 92-95 parts purified water; The benzalkonium chloride is of pharmaceutical grade; The fatty alcohol polyoxyethylene ether is chemically pure; The eucalyptus oil is of food grade. The spray-type disinfectant is prepared by the following steps: S1. Add purified water, fatty alcohol polyoxyethylene ether and eucalyptus oil to the emulsification kettle in sequence, stir for 65-75 minutes to obtain emulsion; S2. Add benzalkonium chloride to the emulsion and continue stirring for 35-45 minutes to obtain a surface disinfectant solution. S3. Dilute the surface disinfectant with water at a ratio of 1:30 to obtain a spray-type disinfectant.

[0020] Experiment: Using the above raw materials, according to different weight parts, conduct sterilization tests for Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Aspergillus niger. The disinfectant solution was sprayed on the surface, the action time was 3 minutes, the test temperature was 25±1℃, the test was repeated three times, the average value was taken, and the test was observed and evaluated.

[0021] The spray-type disinfectant of this invention uses benzalkonium chloride as the main disinfectant and bactericidal component. Combined with eucalyptus oil, it can achieve a good disinfection and bactericidal effect. The composition is simple, which improves the problem of excessive components in disinfectants, which leads to increased preparation difficulty and production costs. Furthermore, the process of first preparing an emulsion of purified water, fatty alcohol polyoxyethylene ether, and eucalyptus oil, and then mixing benzalkonium chloride into it, helps to improve the stability of the disinfectant and facilitates storage and use.

[0022] Example 1 like Figures 2 to 3 As shown, the emulsification vessel used for preparing the spray-type disinfectant includes a vessel body 1. A power shaft 2 is rotatably mounted inside the vessel body 1, and a stirring blade 3 is mounted on the power shaft 2. Multiple movable plates 4 are movably inserted into the side of the stirring blade 3. A reset assembly is mounted on each movable plate 4, and a protective pad 5 is mounted on the outer side of each movable plate 4. A detection assembly that cooperates with the movable plate 4 is installed inside the stirring blade 3. During operation, the protective pad 5 is made of a stretchable and deformable flexible material, sealing the movable plates 4 and the stirring blade 3 to prevent the emulsion from entering the interior of the stirring blade 3. The stirring blade 3 then... During stirring, the movable plate 4 is squeezed by the liquid and moves. In the initial stage of stirring, the emulsion has not yet formed, and the composition inside the vessel 1 is uneven. The objects that the stirring blade 3 touches include solids, liquids, and emulsions. Therefore, the forces on each movable plate 4 are uneven, and the movement amplitude is also different. At this time, each movable plate 4 cannot trigger the detection component at the same time. When the emulsion is stirred evenly, the force exerted by the emulsion on the movable plate 4 is uniform. At this time, the detection component is triggered by the movable plate 4, which can determine that the emulsion has been stirred evenly. This realizes the function of real-time monitoring of the stirring effect of the emulsion in the preparation process of spray disinfectant.

[0023] like Figures 2 to 4 As shown, the detection assembly includes a detection plate 6 slidably installed inside the stirring blade 3. The stirring blade 3 has a mating groove 7 corresponding to the movable plate 4 inside. A rod 8 is fixedly installed on the movable plate 4, inserting into the mating groove 7. A retaining plate 9 is movably inserted into the mating groove 7 inside the detection plate 6. A support spring is installed on the retaining plate 9. A middle block 10 is movably inserted into the mating groove 7, located between the rod 8 and the retaining plate 9. During operation, the stirring blade 3 rotates, causing the detection plate 6 to generate centrifugal force that moves outward. The detection plate 6 has a groove corresponding to the retaining plate 9 inside. Initially, all retaining plates 9 are inserted into the mating groove 7 under the push of the support spring, thus fixing the detection plate 6. Therefore, during the preparation of the emulsion, the detection plate 6 will not move under the action of centrifugal force. Only when all retaining plates 9 are separated from the mating groove 7, and the middle block 10 does not extend beyond the outside of the mating groove 7 and insert into the groove, will the detection plate 6 move. During the stirring process, the movable plate 4 is squeezed by the material inside the vessel body 1, causing it to move inwards towards the stirring blade 3, and squeezing the intermediate block 10 and the clamping plate 9 to move. Figure 4 In the middle, the movable plate 4 moves upward by pressing the middle block 10 and the clamping plate 9 together with the insert rod 8; In the initial stage of stirring, the material distribution inside the vessel 1 is not uniform. During the rotation of the stirring blade 3, the squeezing force on each movable plate 4 is too large or too small, and the range of movement of each movable plate 4 is different, resulting in different ranges of movement of the clamping plate 9. The movable plate 4 with greater force moves a larger range, causing the clamping plate 9 and the intermediate block 10 to be squeezed into the groove; the movable plate 4 with less force moves too little, causing the clamping plate 9 to remain stuck in the mating groove 7. Because the force on the movable plates 4 is uneven, not all the clamping plates 9 can be squeezed out of the mating groove 7 at the same time, and the intermediate blocks 10 are all located in the mating groove 7. Therefore, the detection plate 6 will not move. In the later stage of stirring, after the emulsion is stirred evenly, the squeezing force on the movable plate 4 becomes uniform and reaches a balanced state. At this time, all the clamping plates 9 are squeezed to separate from the mating tank 7, and the middle block 10 is located in the mating tank 7. In addition, the lengths of each insert rod 8 and the middle block 10 can be designed to make their movement range more in line with the actual production situation, so as to ensure that when the emulsion is stirred evenly, all the clamping plates 9 are separated from the mating tank 7 and the middle block 10 is located in the mating tank 7. Therefore, the detection plate 6 can move outward under the action of centrifugal force. By monitoring the state of the detection plate 6, it can be determined that the emulsion has been stirred evenly. In addition, the subsequent stirring speed and stirring time can be adjusted based on this judgment, which improves the problem that when preparing disinfectant, if the emulsion being stirred is not monitored in real time, it is easy to have insufficient or excessive stirring of the emulsion, which affects the quality of the emulsion. like Figure 5 As shown, a tension spring is installed on the detection plate 6, and a sensor 11 is installed inside the stirring blade 3. A T-shaped contact rod corresponding to the sensor 11 is provided on the detection plate 6. During operation, a control unit is installed inside the vessel body 1 to control the stirring operation. The sensor 11 is electrically connected to the control unit. The sensor 11 can be a pressure sensor. In the initial state, the T-shaped contact rod is separated from the sensor 11. After the emulsion is stirred evenly and the detection plate 6 moves under the action of centrifugal force, the T-shaped contact rod contacts the sensor 11. The sensor 11 sends a signal to the control unit. The control unit receives the signal and can then determine that the emulsion has been stirred evenly.

[0024] like Figure 4As shown, the reset assembly includes a sleeve 12 fixedly installed on the inner wall of the movable plate 4. The sleeve 12 is movably sleeved on the outside of the insertion rod 8. A compression spring 13 is installed on the sleeve 12, and a compression spring 14 is installed on the insertion rod 8. A conical plate 15 is fixedly installed on the outside of the insertion rod 8. A baffle 16 is movably inserted into the inside of the stirring blade 3 to block the conical plate 15. A reset spring is installed on the baffle 16. A pressure rod 17 is fixedly installed on the sleeve 12. A wedge is provided on the pressure rod 17. A through hole corresponding to the wedge is opened in the baffle 16. During operation, a limit plate is provided on the insertion rod 8. In the initial state, such as Figure 4 As shown, the movable plate 4 extends outward and is fixed under the push of the compression spring 13, while the compression spring 14 is in a state of no force; the baffle 16 blocks the top of the conical plate 15, thereby fixing the insert rod 8. During the stirring process, the movable plate 4 is squeezed and drives the sleeve 12 to move. After the sleeve 12 moves, it compresses and stores energy by squeezing the compression spring 13 and the compression spring 2 14. As the movable plate 4 continues to move, the sleeve 12 pushes the baffle 16 open through the pressure rod 17. The compression spring 2 14 releases energy and pushes the insertion rod 8 to move upward, so that the insertion rod 8 squeezes the middle block 10 and the clamping plate 9 to move. In the initial stage of stirring, the material distribution inside the vessel 1 is uneven, and the movement of the movable plate 4 is in a state of flux. This may cause the intermediate block 10 and the clamping plate 9 to be temporarily in a state of equilibrium. By setting the sleeve 12, the compression spring 13, the compression spring 14, and the baffle 16, the insertion rod 8 will only move after the movable plate 4 has been moving for a period of time. There is a time difference between the movement of the insertion rod 8 and the movement of the movable plate 4. This time difference can further reduce the possibility that all the clamping plates 9 and the intermediate block 10 are in a temporary state of equilibrium at the same time when the emulsion is not stirred evenly. This improves the situation in the initial stage of stirring where the movement state of the movable plate 4 is constantly changing, which may lead to all the clamping plates 9 and the intermediate block 10 being in a temporary state of equilibrium at the same time, resulting in misjudgment.

[0025] like Figure 4 As shown, a boss 18 is fixedly installed on the inner wall of the movable plate 4. The boss 18 is fixedly connected to the sleeve 12 and is located on the outside of the insertion rod 8. During operation, by setting the boss 18, space is left for the insertion rod 8. In the initial stage of the movement of the movable plate 4, the movable plate 4 drives the sleeve 12 to move through the boss 18. The movable plate 4 will not directly contact the insertion rod 8, which improves the situation where the movable plate 4 may accidentally hit the insertion rod 8.

[0026] like Figure 1-3As shown in Figures 6-7, the stirring blade 3 has a detection hole 19. A chain belt 20 is movably installed inside the detection hole 19. A return torsion spring is installed on the mounting shaft of the chain belt 20. A friction belt 21 is provided on the outer side of the chain belt 20. A one-way rotating plate 22 is fixedly installed on the side of the chain belt 20 away from the detection hole 19. A switch group 23 corresponding to the one-way rotating plate 22 is installed inside the stirring blade 3. During operation, the friction belt 21 has a rough surface, so that the friction belt 21 comes into frictional contact with the emulsion in the vessel body 1. When the emulsion flows on the surface of the friction belt 21, it will drive the friction belt 21 and the chain belt 20 to rotate. The switch group 23 is electrically connected to the control unit in the vessel body 1. The switch group 23 includes two switches, which are located on both sides of the one-way rotating plate 22. The switches can be signal devices that can send signals to the control unit. When the stirring blade 3 rotates to stir, it intermittently opens and closes the detection hole 19. When the detection hole 19 is open, the emulsion flows through the detection hole 19 and contacts the friction belt 21, causing the friction belt 21 and the chain belt 20 to rotate. When the detection hole 19 is closed, the chain belt 20 rotates under the action of the reset torsion spring. After the emulsion drives the chain belt 20 to rotate, the one-way rotating plate 22 moves, in Figure 6 In the middle, the one-way rotating plate 22 moves downward. In the initial state, the one-way rotating plate 22 is in contact with the switch above. In the initial stage of stirring, when the emulsion has not yet formed, the emulsion has poor fluidity. When the emulsion flows, it generates a large frictional force on the friction belt 21, causing the friction belt 21 to rotate to a large extent and the one-way rotating plate 22 to move downward to a large extent. At this time, after the one-way rotating plate 22 moves downward, it contacts the switch below, triggering the switch below and sending a signal to the control unit. Then the friction belt 21 moves back, the one-way rotating plate 22 resets and contacts the switch above, triggering the switch above and sending a signal to the control unit. Therefore, the control unit will receive two signals in a short period of time. After mixing is complete and the emulsion is formed, the emulsion has good fluidity. The friction force generated by the emulsion on the friction belt 21 when it flows is small, the rotation amplitude of the friction belt 21 is small, and the downward movement amplitude of the one-way rotating plate 22 is small. At this time, after the one-way rotating plate 22 moves down, it will not contact the switch below. The switch below is not triggered and no signal is sent. Then the friction belt 21 moves back, the one-way rotating plate 22 resets and contacts the switch above. The switch above is triggered and sends a signal to the control unit. Therefore, the control unit will receive a signal once in a short time. Therefore, by counting the number of signals received in a short period of time, the control unit can determine whether the emulsion's fluidity is up to standard, thus realizing the function of real-time monitoring of the emulsion's fluidity during the preparation of disinfectant.

[0027] like Figure 1-3As shown in Figures 6-7, the stirring blade 3 has a through groove 24 inside, and a rotating shaft 25 is rotatably installed inside the through groove 24. An impeller 26 is installed on the rotating shaft 25. A sealing plate 27 that blocks the detection hole 19 is movably installed on the top of the stirring blade 3. A driven plate 28 is provided on the sealing plate 27. A disc 29 is fixedly installed on the top of the rotating shaft 25 and above the stirring blade 3. A ramp plate 30 corresponding to the driven plate 28 is fixedly installed on the top of the disc 29. A protective cover 31 is fixedly installed on the top of the stirring blade 3. The protective cover 31 covers the outside of the disc 29 and the sealing plate 27. During operation, in the initial state, the sealing plate 27 is located at the bottom of its moving position under the action of gravity. A return spring can also be installed on the sealing plate 27. At this time, the sealing plate 27 blocks the detection hole 19, and the emulsion will not flow into the detection hole 19. The channel 24 is always open. When the stirring blade 3 rotates, the emulsion flows through the channel 24 and drives the rotating shaft 25 and the disc 29 to rotate through the impeller 26. During the rotation of the disc 29, when the ramp plate 30 contacts the driven plate 28, it will squeeze the sealing plate 27 to move upward, causing the sealing plate 27 to be misaligned with the detection hole 19. After the ramp plate 30 is misaligned with the driven plate 28, the sealing plate 27 moves downward again under the action of gravity and blocks the detection hole 19. In this way, the function of intermittently opening and closing the detection hole 19 is realized so as to monitor the flowability of the emulsion in real time. A gear assembly can also be installed between the rotating shaft 25 and the disc 29 to reduce the rotation speed of the disc 29 to adapt to actual production needs. This process does not require an additional electric drive mechanism, reducing costs, and is simple in structure and easy to use.

[0028] Example 2 like Figure 8 As shown in the first embodiment, another embodiment of the present invention is as follows: a drive motor 32 for driving the power shaft 2 is installed on the vessel body 1; during operation, the drive motor 32 is electrically connected to the control unit inside the vessel body 1, and the control unit controls the start of the drive motor 32. A reduction gearbox can also be installed on the drive motor 32 to adjust and control the speed of the power shaft 2.

[0029] Working principle: When the stirring blade 3 stirs the emulsion, the movable plate 4 is squeezed by the liquid and moves. In the initial stage of stirring, the emulsion has not yet formed, and the composition inside the vessel 1 is uneven. The objects that the stirring blade 3 touches include solids, liquids, and emulsions. Therefore, the forces on each movable plate 4 are uneven, and the movement amplitude is also different. At this time, each movable plate 4 cannot trigger the detection component at the same time. When the emulsion is stirred evenly, the force exerted by the emulsion on the movable plate 4 is uniform. At this time, the detection component is triggered by the movable plate 4, which can determine that the emulsion has been stirred evenly. This realizes the function of real-time monitoring of the stirring effect of the emulsion in the preparation process of spray disinfectant.

[0030] The rotation of the stirring blade 3 causes the detection plate 6 to generate centrifugal force that moves it outward. The detection plate 6 has grooves corresponding to the retaining plates 9 inside. In the initial state, all the retaining plates 9 are inserted into the mating groove 7 under the push of the support spring, thereby fixing the detection plate 6. Therefore, the detection plate 6 will not move under the action of centrifugal force during the stirring and preparation of the emulsion. The detection plate 6 will only move when all the retaining plates 9 are separated from the mating groove 7 and the middle block 10 does not extend out of the outside of the mating groove 7 and insert into the groove. During the stirring process, the movable plate 4 is squeezed by the material inside the vessel body 1, causing it to move inwards towards the stirring blade 3, and squeezing the intermediate block 10 and the clamping plate 9 to move. Figure 4 In the middle, the movable plate 4 moves upward by pressing the middle block 10 and the clamping plate 9 together with the insert rod 8; In the initial stage of stirring, the material distribution inside the vessel 1 is not uniform. During the rotation of the stirring blade 3, the squeezing force on each movable plate 4 is too large or too small, and the range of movement of each movable plate 4 is different, resulting in different ranges of movement of the clamping plate 9. The movable plate 4 with greater force moves a larger range, causing the clamping plate 9 and the intermediate block 10 to be squeezed into the groove; the movable plate 4 with less force moves too little, causing the clamping plate 9 to remain stuck in the mating groove 7. Because the force on the movable plates 4 is uneven, not all the clamping plates 9 can be squeezed out of the mating groove 7 at the same time, and the intermediate blocks 10 are all located in the mating groove 7. Therefore, the detection plate 6 will not move. In the later stage of stirring, after the emulsion is stirred evenly, the squeezing force on the movable plate 4 becomes uniform and reaches a balanced state. At this time, all the clamping plates 9 are squeezed to separate from the mating tank 7, and the middle block 10 is located in the mating tank 7. In addition, the lengths of each insert rod 8 and the middle block 10 can be designed to make their movement range more in line with the actual production situation, so as to ensure that when the emulsion is stirred evenly, all the clamping plates 9 are separated from the mating tank 7 and the middle block 10 is located in the mating tank 7. Therefore, the detection plate 6 can move outward under the action of centrifugal force. By monitoring the state of the detection plate 6, it can be determined that the emulsion has been stirred evenly. In addition, the subsequent stirring speed and stirring time can be adjusted based on this judgment, which improves the problem that when preparing disinfectant, if the emulsion being stirred is not monitored in real time, it is easy to have insufficient or excessive stirring of the emulsion, which affects the quality of the emulsion. A control unit is installed inside the vessel body 1 to control the stirring operation. Sensor 11 is electrically connected to the control unit. Sensor 11 can be a pressure sensor. In the initial state, the T-shaped contact rod is separated from the sensor 11. After the emulsion is stirred evenly and the detection plate 6 moves under the action of centrifugal force, the T-shaped contact rod contacts the sensor 11. The sensor 11 sends a signal to the control unit. When the control unit receives the signal, it can determine that the emulsion has been stirred evenly.

[0031] A limit plate is provided on the insertion rod 8. In the initial state, such as Figure 4 As shown, the movable plate 4 extends outward and is fixed under the push of the compression spring 13, while the compression spring 14 is in a state of no force; the baffle 16 blocks the top of the conical plate 15, thereby fixing the insert rod 8. During the stirring process, the movable plate 4 is squeezed and drives the sleeve 12 to move. After the sleeve 12 moves, it compresses and stores energy by squeezing the compression spring 13 and the compression spring 2 14. As the movable plate 4 continues to move, the sleeve 12 pushes the baffle 16 open through the pressure rod 17. The compression spring 2 14 releases energy and pushes the insertion rod 8 to move upward, so that the insertion rod 8 squeezes the middle block 10 and the clamping plate 9 to move. In the initial stage of stirring, the material distribution inside the vessel 1 is uneven, and the movement of the movable plate 4 is in a state of flux. This may cause the intermediate block 10 and the clamping plate 9 to be temporarily in a state of equilibrium. By setting the sleeve 12, the compression spring 13, the compression spring 14, and the baffle 16, the insertion rod 8 will only move after the movable plate 4 has been moving for a period of time. There is a time difference between the movement of the insertion rod 8 and the movement of the movable plate 4. This time difference can further reduce the possibility that all the clamping plates 9 and the intermediate block 10 are in a temporary state of equilibrium at the same time when the emulsion is not stirred evenly. This improves the situation in the initial stage of stirring where the movement state of the movable plate 4 is constantly changing, which may lead to all the clamping plates 9 and the intermediate block 10 being in a temporary state of equilibrium at the same time, resulting in misjudgment.

[0032] The friction belt 21 has a rough surface, which allows the friction belt 21 to come into frictional contact with the emulsion inside the vessel 1. When the emulsion flows on the surface of the friction belt 21, it will drive the friction belt 21 and the chain belt 20 to rotate. The switch group 23 is electrically connected to the control unit inside the vessel 1. The switch group 23 includes two switches, which are located on both sides of the one-way rotating plate 22. The switches can be signal devices, which can send signals to the control unit. When the stirring blade 3 rotates to stir, it intermittently opens and closes the detection hole 19. When the detection hole 19 is open, the emulsion flows through the detection hole 19 and contacts the friction belt 21, causing the friction belt 21 and the chain belt 20 to rotate. When the detection hole 19 is closed, the chain belt 20 rotates under the action of the reset torsion spring. After the emulsion drives the chain belt 20 to rotate, the one-way rotating plate 22 moves, in Figure 6 In the middle, the one-way rotating plate 22 moves downward. In the initial state, the one-way rotating plate 22 is in contact with the switch above. In the initial stage of stirring, when the emulsion has not yet formed, the emulsion has poor fluidity. When the emulsion flows, it generates a large frictional force on the friction belt 21, causing the friction belt 21 to rotate to a large extent and the one-way rotating plate 22 to move downward to a large extent. At this time, after the one-way rotating plate 22 moves downward, it contacts the switch below, triggering the switch below and sending a signal to the control unit. Then the friction belt 21 moves back, the one-way rotating plate 22 resets and contacts the switch above, triggering the switch above and sending a signal to the control unit. Therefore, the control unit will receive two signals in a short period of time. After mixing is complete and the emulsion is formed, the emulsion has good fluidity. The friction force generated by the emulsion on the friction belt 21 when it flows is small, the rotation amplitude of the friction belt 21 is small, and the downward movement amplitude of the one-way rotating plate 22 is small. At this time, after the one-way rotating plate 22 moves down, it will not contact the switch below. The switch below is not triggered and no signal is sent. Then the friction belt 21 moves back, the one-way rotating plate 22 resets and contacts the switch above. The switch above is triggered and sends a signal to the control unit. Therefore, the control unit will receive a signal once in a short time. Therefore, by counting the number of signals received in a short period of time, the control unit can determine whether the emulsion's fluidity is up to standard, thus realizing the function of real-time monitoring of the emulsion's fluidity during the preparation of disinfectant.

[0033] In the initial state, the sealing plate 27 is located at the bottom of its moving position under the action of gravity. A reset spring can also be installed on the sealing plate 27. At this time, the sealing plate 27 will block the detection hole 19, and the emulsion will not flow into the detection hole 19. The channel 24 is always open. When the stirring blade 3 rotates, the emulsion flows through the channel 24 and drives the rotating shaft 25 and the disc 29 to rotate through the impeller 26. During the rotation of the disc 29, when the ramp plate 30 contacts the driven plate 28, it will squeeze the sealing plate 27 to move upward, causing the sealing plate 27 to be misaligned with the detection hole 19. After the ramp plate 30 is misaligned with the driven plate 28, the sealing plate 27 moves downward again under the action of gravity and blocks the detection hole 19. In this way, the function of intermittently opening and closing the detection hole 19 is realized so as to monitor the flowability of the emulsion in real time. A gear assembly can also be installed between the rotating shaft 25 and the disc 29 to reduce the rotation speed of the disc 29 to adapt to actual production needs. This process does not require an additional electric drive mechanism, reducing costs, and is simple in structure and easy to use.
