Description

Technical Field

[0001] This invention belongs to the field of disinfection device technology, specifically a low-concentration hypochlorous acid water temperature control device, method, and application. Background Technology

[0002] Hypochlorous acid disinfectant has the characteristics of broad-spectrum bactericidal action, non-toxicity, non-irritation, safety, and no residue. Compared with sodium hypochlorite disinfectant widely used in the market, its bactericidal ability is dozens of times stronger, and it does not cause any harm or pollution to the human body and the environment. It leaves no harmful residues, is safe for mothers and infants, is harmless when ingested, and does not cause drug resistance. Therefore, in the medical industry, hypochlorous acid water is often used for disinfection of water, indoor air, materials and instruments, secondary water supply equipment surfaces, hands, skin, and mucous membranes to effectively kill bacteria. Hypochlorous acid water is generally produced by the electrolysis of dilute hydrochloric acid or salt solution.

[0003] At concentrations below 45 ppm, hypochlorous acid water is highly sensitive to temperature. Currently, hypochlorous acid water is used at room temperature, and the water temperature changes with room temperature. The activity of hypochlorous acid water is closely related to temperature. When the temperature is too low, the disinfection effect of hypochlorous acid will be significantly weakened, requiring a longer reaction time. When the temperature is too high, the decomposition rate of hypochlorous acid will accelerate, and the effective concentration will drop rapidly, resulting in unstable sterilization effect of hypochlorous acid water. At the same time, after the hypochlorous acid water disinfection device is used, some residual hypochlorous acid water will remain inside. This residual hypochlorous acid water can easily corrode the internal components of the disinfection device and adversely affect the sterilization effect of the disinfection device in the initial period after subsequent use. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a low-concentration hypochlorous acid water temperature control device, method, and application for constant temperature treatment of hypochlorous acid water in the disinfection device to ensure stable sterilization effect, and to fully drain and empty the remaining hypochlorous acid water in the disinfection device after use to avoid corrosion of the disinfection device.

[0005] The technical solution adopted by this invention to solve its technical problem is: a low-concentration hypochlorous acid water temperature control device of this invention, comprising:

[0006] Water tank;

[0007] Temperature sensor, the temperature sensor is attached to the surface of the water tank;

[0008] A constant temperature module is provided, which is equipped with a water tank. The constant temperature module includes a semiconductor cooling chip, a controller that controls the power supply of the constant temperature module, and a heat dissipation component for heat dissipation of the semiconductor cooling chip. The sensor and the controller are connected by a signal.

[0009] Pressure tanks are used to store hypochlorous acid water and are connected to water tanks via pipes.

[0010] This invention also provides a method for temperature control of low-concentration hypochlorous acid water, using the aforementioned low-concentration hypochlorous acid water temperature control device for temperature control, the method comprising the following steps:

[0011] S1: Control the external air source to inject gas from the regulating pipe, adjust the pressure in the elastic layer, and make the elastic layer tightly adhere to the inner wall of the pressure tank. At this time, the pressure value in the elastic layer is set to P2. At the same time, control the external air source to inject gas from the air inlet pipe, increase the pressure in the space between the floating block and the sealing cover, and make the floating block contact the bottom surface of the pressure tank.

[0012] S2: Based on step S, adjust the pressure inside the elastic layer so that the elastic layer just contacts the inner wall of the pressure tank. At this time, the pressure value inside the elastic layer is set to P1, and P1 is less than P2. At the same time, control the external air source to exhaust air from the exhaust pipe so that the pressure in the space between the floating block and the sealing cover is the same as the external atmospheric pressure.

[0013] S3: The temperature of the outer wall of the water tank is detected by a temperature sensor. Based on the detection result, the controller controls the operation of the semiconductor cooling chip. Then, the prepared hypochlorous acid water is introduced through the water inlet pipe. After passing through the constant temperature module, the hypochlorous acid water reaches the set constant temperature. Then, the hypochlorous acid water enters the pressure tank for temporary storage. When the hypochlorous acid water enters the pressure tank, it pushes the floating block upward, and the floating block comes into contact with the liquid surface in the pressure tank.

[0014] S4: When hypochlorous acid water is needed, the hypochlorous acid water is discharged from the pressure tank through the solenoid valve on the outlet pipe.

[0015] The present invention also provides the application of low-concentration hypochlorous acid water at constant temperature in the disinfection of human body surface and oral cavity, using the above-mentioned low-concentration hypochlorous acid water temperature control device for temperature control.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention incorporates a constant temperature module, a water tank, a semiconductor cooling chip, and a pressure vessel. Hypochlorous acid water flows through the water tank, allowing the controller to operate the semiconductor cooling chip and adjust the temperature of the hypochlorous acid water to maintain a constant temperature. This slows down the decomposition of hypochlorous acid in the water, ensuring effective sterilization. Simultaneously, the pressure vessel temporarily stores the temperature-controlled hypochlorous acid water, guaranteeing a stable supply during disinfection and ensuring optimal disinfection results.

[0018] 2. This invention, by setting up a floating block, an elastic layer, an adjusting pipe, an adhesive layer, a buffer tank, and an elastic bladder, allows gas to be injected or extracted into the space above the floating block after use. This causes the floating block to move up and down within the pressure tank under pressure. This, combined with the pure water transported through the pure water pipe, drains and empties the remaining hypochlorous acid water in the pressure tank, the constant temperature module, and the pipes. This prevents the remaining hypochlorous acid water from corroding the disinfection device and affecting the sterilization effect during the initial period when the disinfection device is used again.

Detailed Implementation

[0033] 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.

[0034] Example 1:

[0035] like Figures 1 to 4 As shown, the low-concentration hypochlorous acid water temperature control device of the present invention includes:

[0036] Water tank 23;

[0037] Temperature sensor, the temperature sensor is attached to the surface of the water tank;

[0038] The temperature control module 2 is equipped with a water tank 23. The temperature control module 2 includes a semiconductor cooling chip 22, a controller for controlling the power supply of the temperature control module 2, and a heat dissipation component for heat dissipation of the semiconductor cooling chip 22. The sensor and the controller are connected by a signal.

[0039] Pressure tank 3, used to store hypochlorous acid water, is connected to water tank 23 via a pipe;

[0040] During operation, hypochlorous acid water is introduced into the constant temperature module 2 through the inlet pipe 11. The constant temperature module 2 heats or cools the hypochlorous acid water to keep it at a constant temperature. Then, the hypochlorous acid water is transported to the pressure tank 3 for temporary storage. When disinfection is required, the hypochlorous acid water in the pressure tank 3 is discharged from the outlet pipe 12 to disinfect the environment, equipment, water, etc. to be disinfected.

[0041] When hypochlorous acid water is introduced into the thermostatic module 2, it enters the water tank 23. At this time, the temperature of the water tank 23 is detected by a temperature sensor.

[0042] The heat dissipation assembly includes a radiator 21 and a fan 25. A water tank 23 is mounted on the radiator 21 via a pressure strip 24. A semiconductor cooling chip 22 is installed between the water tank 23 and the radiator 21. A fan 25 is mounted on the side of the radiator 21 away from the water tank 23.

[0043] When the temperature sensor detects that the temperature of the water tank 23 is higher than the required temperature of the hypochlorous acid water, the controller applies a positive voltage to the thermoelectric cooler 22, causing the thermoelectric cooler 22 to start cooling, thereby reducing the temperature of the hypochlorous acid water passing through the water tank 23 to a suitable temperature. At the same time, the heat from the hot end of the thermoelectric cooler 22 is dissipated by the fan 25.

[0044] When the temperature sensor detects that the temperature of the water tank 23 is lower than the required temperature of the hypochlorous acid water, the controller applies a negative charge to the thermoelectric cooler 22, causing the thermoelectric cooler 22 to heat up and raise the temperature of the hypochlorous acid water passing through the water tank 23 to a suitable temperature. At the same time, the hot end of the thermoelectric cooler 22 transfers the heat of the air to the thermoelectric cooler 22 through the fan 25 to prevent the temperature of the thermoelectric cooler 22 from being too low.

[0045] Meanwhile, the hypochlorous acid water, which maintains a constant temperature after passing through water tank 23, enters pressure tank 3 through connecting pipe 14. The heat exchange between the hypochlorous acid water inside pressure tank 3 and the external environment is isolated by the heat insulation layer set on the outside of pressure tank 3, so as to keep the temperature of hypochlorous acid water inside pressure tank 3 as constant as possible. Furthermore, the pressure tank 3 isolates light from the external environment, further preventing the decomposition of hypochlorous acid and ensuring the sterilization stability of hypochlorous acid water.

[0046] Example 2:

[0047] like Figure 9 As shown, the product's appearance is the same as in Embodiment 1. The difference from Embodiment 1 is that it also includes a housing 1. The housing 1 contains a thermostatic module 2 and a pressure tank 3. The thermostatic module 2 is equipped with a water inlet pipe 11. The thermostatic module 2 and the pressure tank 3 are connected to each other via a connecting pipe 14. The pressure tank 3 is connected to a secondary thermostatic module, which is connected to an outlet pipe. It should be noted that the secondary thermostatic module has the same structure as the thermostatic module 2, except that the secondary thermostatic module 2 is connected to the outlet pipe 12. The temperature of the hypochlorous acid water is further controlled by the secondary thermostatic module 2, so that the low-concentration hypochlorous acid water achieves a better disinfection effect at the set temperature.

[0048] Example 3:

[0049] like Figures 1-8 As shown, the difference from Embodiment 1 is that it also includes a housing 1, in which a constant temperature module 2 and a pressure tank 3 are installed. A water inlet pipe 11 is installed on the pressure tank 3. The constant temperature module 2 and the pressure tank 3 are connected to each other through a connecting pipe 14. A water outlet pipe 12 is installed on the constant temperature module 2.

[0050] In this embodiment, the water inlet pipe 11 is connected to the pressure tank 3, and the pressure tank 3 is connected to the constant temperature module 2. When hypochlorous acid water is needed, it is only necessary to transport the hypochlorous acid water from the pressure tank 3 to the constant temperature module 2 through the pressure tank 3 to achieve temperature regulation, and then discharge it from the water outlet pipe 12 for use. The difference between this method and the second embodiment is that it saves the number of constant temperature modules 2 and achieves the effect of immediate use after constant temperature.

[0051] Example 4:

[0052] like Figure 10 , Figure 11 As shown, when it is necessary to reduce the concentration of hypochlorous acid water, during the process of constant-temperature hypochlorous acid water being output to the outside for sterilization and disinfection, the concentration of the output hypochlorous acid water is detected. The controller controls the external water source to deliver pure water from the pure water pipe 13 to mix with the hypochlorous acid water discharged from the outlet pipe 12, thereby adjusting the concentration of the hypochlorous acid water used for sterilization and disinfection, so that the concentration of the hypochlorous acid water is within a suitable range, making it more applicable.

[0053] Meanwhile, the space inside the water tank 23 of the constant temperature module 2 is divided, and a double-lumen pipe is used as the inlet pipe 11 and the connecting pipe 14, so that the purified water supplied from the outside can pass through the constant temperature module 2 together with the hypochlorous acid water and the temperature is adjusted so that the temperature of the purified water and the hypochlorous acid water is the same. This ensures that the temperature of the purified water and the hypochlorous acid water remains constant and suitable after they are mixed at the outlet pipe 12, thus ensuring the sterilization and disinfection effect of the hypochlorous acid water and the comfort during use. It also avoids the direct mixing of purified water with the constant temperature hypochlorous acid water to adjust the concentration of the hypochlorous acid water, which would cause a sudden change in the temperature of the hypochlorous acid water discharged at the outlet pipe 12 and affect the use of the hypochlorous acid water.

[0054] In this invention, since a floating block 32 is installed inside the pressure tank 3, when hypochlorous acid water enters the pressure tank 3, the lower surface of the floating block 32 is in contact with the liquid surface of the hypochlorous acid water, so that the liquid surface of the hypochlorous acid water does not come into contact with the air, thereby reducing the decomposition, volatilization and reaction of hypochlorous acid in the water and ensuring the stability of the sterilization and disinfection of hypochlorous acid water.

[0055] Meanwhile, when the hypochlorous acid water is discharged from the pressure tank 3 through the outlet pipe 12, and the flow of the hypochlorous acid water is relatively slow and not smooth, the controller controls the external air source to inject gas into the pressure tank 3 from the air inlet pipe 16, increasing the pressure in the pressure tank 3, promoting the smooth and stable discharge of hypochlorous acid water, and ensuring the normal use of the disinfection device.

[0056] Meanwhile, when the disinfection device is stopped and some hypochlorous acid water still exists in the pressure tank 3, the controller controls the external air source to inject gas from the air inlet pipe 16, which increases the pressure in the space between the floating block 32 and the sealing cover 31. Under the pressure, the floating block 32 moves downward, squeezing the remaining hypochlorous acid water in the pressure tank 3, so that the remaining hypochlorous acid water can be discharged from the outlet pipe 12. This ensures that the remaining hypochlorous acid water in the pressure tank 3 is discharged and emptied, avoiding corrosion of the pressure tank 3 and pipelines by the residual hypochlorous acid water, and preventing the remaining hypochlorous acid water from remaining in the pressure tank 3. If the disinfection device is used again, the new hypochlorous acid water will mix with the deteriorated and ineffective hypochlorous acid water in the pressure tank 3, resulting in poor sterilization and disinfection effect of the initially discharged hypochlorous acid water when the disinfection device is used again, affecting the sterilization and disinfection effect of the disinfection device and creating safety hazards.

[0057] In one embodiment of the present invention, an elastic layer 33 is installed on the side of the floating block 32, and a cavity is opened in the elastic layer 33. An adjusting pipe 331 is installed on the sealing cover 31. The adjusting pipe 331 is an elastic air pipe. The adjusting pipe 331 is interconnected with the cavity and interconnected with an external air source.

[0058] By installing an elastic layer 33 on the side of the floating block 32, the floating block 32 and the inner wall of the pressure tank 3 are made to slide and seal in contact. This prevents the hypochlorous acid water in the pressure tank 3 from flowing upward from the gap between the floating block 32 and the inner wall of the pressure tank 3 when the floating block 32 moves up and down in the pressure tank 3, thus preventing leakage of hypochlorous acid water and affecting the normal use of the disinfection device.

[0059] Meanwhile, by adjusting the pipe 331, the external air source and the cavity inside the elastic layer 33 are interconnected, so that the controller controls the external air source to inject or extract gas into the cavity and adjust the pressure in the cavity inside the elastic layer 33.

[0060] When hypochlorous acid water enters pressure tank 3 from constant temperature module 2 and is discharged from pressure tank 3 for sterilization and disinfection, the controller controls the external air source to adjust the pressure in elastic layer 33 to be relatively small. At this time, the pressure value in elastic layer 33 is set to P1, so that elastic layer 33 just contacts the inner wall of pressure tank 3, so that the pressure of elastic layer 33 on the inner wall of pressure tank 3 is relatively small, so that the friction between elastic layer 33 and pressure tank 3 is relatively small, which makes it easier for floating block 32 to be lifted by hypochlorous acid water or to move downward under the action of gravity, avoiding the floating block 32 from getting stuck and affecting the normal use of disinfection device;

[0061] When the disinfection device is finished and the remaining hypochlorous acid water in the pressure tank 3 needs to be drained, the controller controls the external air source to adjust the pressure in the elastic layer 33, making the pressure in the elastic layer 33 relatively high. At this time, the pressure value in the elastic layer 33 is set to P2, so that the elastic layer 33 is tightly attached to the inner wall of the pressure tank 3, which fully avoids the gap between the elastic layer 33 and the inner wall of the pressure tank 3. This prevents the remaining hypochlorous acid water from passing through the gap when squeezed and splashing onto the floating block 32, affecting the drainage and emptying effect of the remaining hypochlorous acid water in the pressure tank 3, and causing the pressure tank 3 and pipelines to be at risk of corrosion, thus affecting the service life of the disinfection device.

[0062] In one embodiment of the present invention, an elastic liquid tube 15 is installed on the sealing cover 31. One end of the elastic liquid tube 15 is installed on the floating block 32, and the other end of the elastic liquid tube 15 is connected to the water outlet pipe 12. The outlet of the elastic liquid tube 15 on the floating block 32 is located on the lower surface of the floating block 32.

[0063] Solenoid valves are installed on the water inlet pipe 11, water outlet pipe 12, pure water pipe 13, air inlet pipe 16 and air outlet pipe 17 respectively;

[0064] The floating block 32 is connected to the outlet pipe 12 via the opening on its lower surface through the elastic liquid pipe 15. When using hypochlorous acid water for sterilization, as the floating block 32 comes into contact with the surface of the hypochlorous acid water in the pressure tank 3, the hypochlorous acid water is drawn from the elastic liquid pipe 15 and transported to the outlet pipe 12. Afterward, the hypochlorous acid water is discharged from the outlet pipe 12 and sterilization is performed. During this process, if the movement of the floating block 32 becomes stuck or jammed, resulting in a gap between the floating block 32 and the surface of the hypochlorous acid water... The absorption of hypochlorous acid water by the outlet of the elastic liquid pipe 15 located on the lower surface of the floating block 32 will be affected. That is, the hypochlorous acid water discharged from the outlet pipe 12 will stop or be discharged intermittently. This indicates the movement state and relative position of the floating block 32 in the pressure tank 3, and prevents the floating block 32 from separating from the surface of the hypochlorous acid water, so that the surface of the hypochlorous acid water comes into contact with the outside air, causing the hypochlorous acid in the water to decompose, volatilize and react, affecting the stability of the sterilization and disinfection effect of the hypochlorous acid water.

[0065] Simultaneously, when the disinfection device is stopped and the remaining hypochlorous acid water in pressure tank 3 needs to be drained, the valves on the inlet pipe 11, pure water pipe 13, and air inlet pipe 16 are closed. Then, gas is injected through the air inlet pipe 16, increasing the pressure in the space between the floating block 32 and the sealing cover 31. This causes the floating block 32 to move downwards under pressure, squeezing the remaining hypochlorous acid water in pressure tank 3. The hypochlorous acid water is then discharged through the elastic liquid pipe 15 and the outlet pipe 12, thus draining and emptying the remaining hypochlorous acid water. Afterward, the valve on the air inlet pipe 16 is closed, and the valve on the exhaust pipe 17 is opened. Gas is extracted from the exhaust pipe 17, causing the floating block 32 and the sealing cover 31 to... The pressure in the space between 1 decreases, causing the floating block 32 to move upward under pressure. Then, the water outlet pipe 12 is closed and the pure water pipe 13 is opened, allowing pure water to flow back into the elastic liquid pipe 15 and then spray into the pressure tank 3, thereby cleaning the residual hypochlorous acid water on the inner wall of the pressure tank 3. After that, the pure water pipe 13 and the exhaust pipe 17 are closed again, and the water outlet pipe 12 and the air inlet pipe 16 are opened. Gas is injected from the air inlet pipe 16, causing the floating block 32 to move downward and discharge the water left in the pressure tank 3 after cleaning. This effectively reduces the amount of residual hypochlorous acid water, prevents corrosion of the pressure tank 3 or the pipeline, and ensures the normal operation of the disinfection device.

[0066] In one embodiment of the present invention, a bracket 352 is installed in the outlet of the elastic fluid tube 15 on the floating block 32, a slide rod 351 is slidably installed on the bracket 352, a movable piece 35 is installed at the lower end of the slide rod 351, the diameter of the movable piece 35 is smaller than the diameter of the outlet of the elastic fluid tube 15, and the length of the slide rod 351 is greater than the distance between the bracket 352 and the outlet of the elastic fluid tube 15.

[0067] When purified water enters the elastic liquid tube 15 in reverse, it impacts the movable plate 35 at the outlet of the elastic liquid tube 15, causing the movable plate 35 and the slide rod 351 to move downwards until the slide rod 351 is fully extended and the movable plate 35 reaches the outside of the outlet of the elastic liquid tube 15. At this time, after the purified water is sprayed out from the outlet of the elastic liquid tube 15 in reverse, it impacts the movable plate 35, which guides and directs the purified water towards the inner wall surface of the pressure tank 3. This allows the sprayed purified water to flush and clean the inner wall of the pressure tank 3, preventing residual hypochlorous acid water on the inner wall of the pressure tank 3. Otherwise, the floating block 32 may not completely drain or empty the hypochlorous acid water from the pressure tank 3, which could lead to corrosion of the pressure tank 3 and affect the service life of the disinfection device.

[0068] In one embodiment of the present invention, the movable piece 35 is umbrella-shaped, and the protruding surface of the movable piece 35 faces the bottom surface of the pressure tank 3.

[0069] Because the movable plate 35 is umbrella-shaped and its convex surface faces the bottom of the pressure tank 3, after the pure water is sprayed out in the opposite direction from the outlet of the elastic liquid pipe 15, the pure water will be affected by the arc-shaped surface on the movable plate 35 and spray out diagonally upwards. This allows the sprayed pure water to wash the lower surface of the floating block 32. At the same time, after the pure water impacts the lower surface of the floating block 32, it will be guided by the lower surface of the floating block 32, so that the sprayed pure water contacts the angle and turning point between the floating block 32 and the inner wall of the storage tank. This avoids dead corners and angles between the floating block 32 and the inner wall of the storage tank, which would result in the presence of hypochlorous acid water residue, affecting the normal use of the disinfection device, causing corrosion of the disinfection device, and shortening the service life of the disinfection device.

[0070] In one embodiment of the present invention, an adhesive layer 34 is installed on the lower surface of the floating block 32. The adhesive layer 34 is elastic, and the outlet of the elastic liquid tube 15 on the floating block 32 penetrates the adhesive layer 34.

[0071] When the floating block 32 moves downward to the lower part of the pressure tank 3, the bonding layer 34 on the lower surface of the floating block 32 comes into contact with the bottom surface of the pressure tank 3, so that the surface of the floating block 32 and the bottom surface of the pressure tank 3 are in full contact, avoiding gaps between them, which would cause hypochlorous acid water residue, corrode the pressure tank 3, affect the service life of the disinfection device and the disinfection and sterilization effect in the initial period of use when it is reused.

[0072] At the same time, by having the bonding layer 34 in contact with the bottom surface of the pressure tank 3, the contact and collision between the floating block 32 and the bottom surface of the pressure tank 3 are avoided, and the hydrophobic coatings covering the surfaces of both, such as polytetrafluoroethylene coatings, are prevented from being damaged, resulting in corrosion and affecting the normal use and service life of the disinfection device.

[0073] In one embodiment of the present invention, the thickness of the bonding layer 34 gradually decreases from the edge to the middle, and the outlet of the elastic fluid tube 15 is located at the middle position on the lower surface of the bonding layer 34.

[0074] Because the thickness at the upper edge of the bonding layer 34 is greater than that at the middle position, when the floating block 32 moves downward, the edge of the bonding layer 34 will first contact the bottom surface of the pressure tank 3. Then, as the floating block 32 descends, the edge of the bonding layer 34 will be squeezed and undergo elastic deformation. During this process, the hypochlorous acid water present at the bottom surface of the pressure tank 3 is guided and collected by the lower surface of the bonding layer 34, which facilitates the absorption of the remaining hypochlorous acid water by the outlet of the elastic liquid pipe 15 located at the middle position of the lower surface of the floating block 32. This allows the remaining hypochlorous acid water in the pressure tank 3 to be collected and discharged, avoiding residue, ensuring the normal use of the disinfection device and avoiding affecting its service life.

[0075] In one embodiment of the present invention, a buffer tank 4 is installed on the water inlet pipe 11, and an elastic bladder 41 is installed inside the buffer tank 4. There is a gap between the outer wall of the elastic bladder 41 and the inner wall of the buffer tank 4, and the water inlet pipe 11 is connected to the elastic bladder 41.

[0076] When the disinfection device is empty after use, open the valve on the pure water pipe 13 and close the valves on the outlet pipe 12 and inlet pipe 11. This allows pure water to flow back into the space containing the hypochlorous acid in the constant temperature module 2 through the transfer in the pressure tank 3, and the elastic bladder 41 to fully expand in the buffer tank 4. Then, close the valve on the pure water pipe 13 and evacuate air from the exhaust pipe 17. This causes the floating block 32 to move upward under pressure, drawing the liquid from the elastic bladder 41, water tank 23, and connecting pipe 14 into the pressure tank 3. After emptying the liquid in the pressure tank 3, repeat the above operation several times to thoroughly rinse and clean the constant temperature module 2, connecting pipe 14, and pressure tank 3. This prevents the hypochlorous acid from remaining in the constant temperature module 2, connecting pipe 14, and pressure tank 3, which could corrode the disinfection device and cause poor sterilization performance of the hypochlorous acid output during the initial period after the disinfection device is reused, thus affecting the sterilization effect.

[0077] It should be noted that the temperature sensor in this invention is an NTC temperature sensor.

[0078] Example 5:

[0079] The present invention also provides a method for temperature control of low-concentration hypochlorous acid water, the method being applicable to the low-concentration hypochlorous acid water temperature control device described in any of the above claims, the method comprising the following steps:

[0080] S1: Control the external air source to inject gas from the regulating pipe 331, adjust the pressure in the elastic layer 33 so that the elastic layer 33 is in close contact with the inner wall of the pressure tank 3. At this time, the pressure value in the elastic layer 33 is set to P2. At the same time, control the external air source to inject gas from the air inlet pipe 16 to increase the pressure in the space between the floating block 32 and the sealing cover, so that the floating block 32 and the bottom surface of the pressure tank 3 come into contact with each other.

[0081] S2: Based on step S1, adjust the pressure inside the elastic layer 33 so that the elastic layer 33 just contacts the inner wall of the pressure tank 3. At this time, the pressure value inside the elastic layer 33 is set to P1, and P1 is less than P2. At the same time, control the external air source to exhaust from the exhaust pipe 17 so that the pressure in the space between the floating block 32 and the sealing cover is the same as the external atmospheric pressure.

[0082] S3: The temperature of the outer wall of the water tank 23 is detected by the temperature sensor. Based on the detection result, the controller controls the operation of the semiconductor cooling chip 22. Then, the prepared hypochlorous acid water is introduced from the water inlet pipe 11, so that the hypochlorous acid water reaches the set constant temperature after passing through the constant temperature module 2. Then, the hypochlorous acid water enters the pressure tank 3 for temporary storage. When the hypochlorous acid water enters the pressure tank 3, the floating block 32 is pushed upward, and the floating block 32 comes into contact with the liquid surface in the pressure tank 3.

[0083] Alternatively, low-concentration hypochlorous acid water enters the pressure tank 3 through the inlet pipe 11 and is stored in the pressure tank 3. When needed, the hypochlorous acid water enters the constant temperature module 2 through the pressure tank 3 for temperature adjustment, and is discharged from the outlet pipe 12 after adjustment.

[0084] S4: When hypochlorous acid water is needed, it can be drained using the method described in S3;

[0085] S5: After use, close the valves on the inlet pipe 11, the pure water pipe 13, and the air inlet pipe 16. Then, adjust the pressure in the elastic layer 33 to P2. At the same time, draw air out from the outlet pipe to make the space between the floating block 32 and the sealing cover negative pressure. Under the action of negative pressure, the floating block 32 moves upward to the middle of the pressure tank 3. Then, open the valve on the pure water pipe 13 and close the valve on the outlet pipe 12 to allow the pure water to flow back into the space of hypochlorous acid water in the constant temperature module 2 through the transfer of the pressure tank 3, and make the elastic bladder 41 fully expand in the buffer tank 4.

[0086] S6: Based on step S5, close the valve on the pure water pipe 13 and continue to draw air out from the exhaust pipe 17, causing the floating block 32 to move upward to the upper part of the pressure tank 3, thereby causing the elastic bladder 41 to contract and discharge the hypochlorous acid water in the constant temperature module 2 and the connecting pipe 14 into the pressure tank 3. After that, close the valves on the connecting pipe 14 and the exhaust pipe 17 and inject gas from the air inlet pipe 16, causing the floating block 32 to gradually move downward, emptying and draining the remaining hypochlorous acid water in the pressure tank 3, and preventing the pressure tank 3 and the constant temperature module 2 from being corroded.

[0087] S7: Repeat steps S5-S6 until the concentration of hypochlorous acid in the liquid discharged from outlet pipe 12 is zero.

[0088] Example 6:

[0089] The application of low-concentration hypochlorous acid water at constant temperature in the disinfection of human body surfaces and oral cavity involves using the aforementioned low-concentration hypochlorous acid water temperature control device for temperature control.

[0090] Low-concentration hypochlorous acid water (effective chlorine concentration 20~100mg / L) is significantly less effective at disinfecting human body surfaces, oral mucosa, and medical device surfaces than under constant temperature control conditions of 25℃±2℃ without constant temperature control.

[0091] The effective chlorine concentrations were divided into four levels: 25 mg / L, 50 mg / L, 75 mg / L, and 100 mg / L. The constant temperature group was controlled at 25℃±2℃, while the non-constant temperature group was controlled at natural ambient temperature fluctuations of 10~35℃. The data were the average of three parallel tests, with a deviation of ≤4%. The kill rate was measured in %, the residual colony count in CFU / piece, and the duration of effectiveness in min.

[0097]

[0098] The specific workflow is as follows:

[0099] During operation, the water inlet pipe 11 is connected to an external water pump, which pumps hypochlorous acid water from the water inlet pipe 11 into the constant temperature module 2. The constant temperature module 2 heats or cools the hypochlorous acid water, and then the hypochlorous acid water is transported to the pressure tank 3 for temporary storage.

[0100] When hypochlorous acid water is introduced into the temperature control module 2, it will enter the water tank 23. At this time, the room temperature is detected.

[0101] When the room temperature is higher than the required temperature of the hypochlorous acid water, the controller applies a positive voltage to the semiconductor cooling chip 22, causing the semiconductor cooling chip 22 to start cooling, thereby reducing the temperature of the hypochlorous acid water passing through the water tank 23 to a suitable temperature.

[0102] When the room temperature is lower than the required temperature of the hypochlorous acid water, the controller applies a negative charge to the semiconductor cooling chip 22, causing the semiconductor cooling chip 22 to heat up and raise the temperature of the hypochlorous acid water passing through the water tank 23 to a suitable temperature.

[0103] Meanwhile, the hypochlorous acid water that has passed through water tank 23 and whose temperature is kept constant will enter the pressure tank 3 through connecting pipe 14. The heat exchange between the hypochlorous acid water in the pressure tank 3 and the external environment is isolated by the heat insulation layer set on the outside of the pressure tank 3, and the pressure tank 3 is used to block the light in the external environment.

[0104] Meanwhile, when the constant-temperature hypochlorous acid water is output to the outside for sterilization and disinfection, the concentration of the output hypochlorous acid water is detected. Then, the controller controls the external water source to deliver pure water from the pure water pipe 13 to mix with the hypochlorous acid water discharged from the outlet pipe 12, thereby adjusting the concentration of the hypochlorous acid water used for sterilization and disinfection.

[0105] Meanwhile, the space in the water tank 23 inside the constant temperature module 2 is divided, and a double-lumen pipe is used as the water inlet pipe 11 and the connecting pipe 14, so that the pure water delivered from the outside can pass through the constant temperature module 2 together with the hypochlorous acid water and the temperature is adjusted.

[0106] Meanwhile, since a floating block 32 is installed inside the pressure tank 3, when hypochlorous acid water enters the pressure tank 3, the lower surface of the floating block 32 is in contact with the liquid surface of the hypochlorous acid water, so that the liquid surface of the hypochlorous acid water does not come into contact with the air.

[0107] Meanwhile, when the hypochlorous acid water is discharged from the pressure tank 3 through the outlet pipe 12, and the flow of the hypochlorous acid water is relatively slow and not smooth, the controller controls the external air source to inject gas into the pressure tank 3 from the air inlet pipe 16 to increase the pressure inside the pressure tank 3 and promote the smooth and stable discharge of hypochlorous acid water.

[0108] Meanwhile, when the disinfection device is stopped and there is still some hypochlorous acid water in the pressure tank 3, the controller controls the external air source to inject gas from the air inlet pipe 16, which increases the pressure in the space between the floating block 32 and the sealing cover 31. This causes the floating block 32 to move downward under pressure, squeezing the remaining hypochlorous acid water in the pressure tank 3, so that the remaining hypochlorous acid water can be discharged from the water outlet pipe 12, and to prevent the remaining hypochlorous acid water from remaining in the pressure tank 3. This would cause the new hypochlorous acid water to mix with the deteriorated and ineffective hypochlorous acid water in the pressure tank 3 when the disinfection device is used again, resulting in poor sterilization and disinfection effect of the hypochlorous acid water discharged at the beginning when the disinfection device is used again.

[0109] By installing an elastic layer 33 on the side of the floating block 32, a sliding seal contact is made between the floating block 32 and the inner wall of the pressure tank 3.

[0110] Simultaneously, by adjusting pipe 331, the external air source is connected to the cavity within the elastic layer 33, thereby enabling the controller to control the external air source to inject or extract gas into the cavity, adjusting the pressure within the cavity of the elastic layer 33.

[0111] When hypochlorous acid water enters pressure tank 3 from constant temperature module 2 and is discharged from pressure tank 3 for sterilization and disinfection, the controller controls the external air source to adjust the pressure in elastic layer 33 to be relatively small. At this time, the pressure value in elastic layer 33 is set to P1, so that elastic layer 33 just contacts the inner wall of pressure tank 3, which makes it easy for floating block 32 to be lifted by hypochlorous acid water or floating block 32 to move downward under the action of gravity.

[0112] When the disinfection device is finished and the remaining hypochlorous acid water in the pressure tank 3 needs to be discharged, the controller controls the external air source to adjust the pressure in the elastic layer 33 so that the pressure in the elastic layer 33 is relatively large. At this time, the pressure value in the elastic layer 33 is set to P2, so that the elastic layer 33 is tightly attached to the inner wall of the pressure tank 3, and the gap between the elastic layer 33 and the inner wall of the pressure tank 3 is fully avoided.

[0113] The opening on the lower surface of the floating block 32 and the outlet pipe 12 are connected by the elastic liquid pipe 15. When using the output hypochlorous acid water for sterilization and disinfection, as the floating block 32 comes into contact with the surface of the hypochlorous acid water in the pressure tank 3, the hypochlorous acid water will be drawn from the elastic liquid pipe 15 and transported to the outlet pipe 12. Then, the hypochlorous acid water will be discharged from the outlet pipe 12 and sterilization and disinfection will be carried out. During this process, when the movement of the floating block 32 is stuck or jammed, resulting in a gap between the floating block 32 and the surface of the hypochlorous acid water, the absorption of hypochlorous acid water by the outlet of the elastic liquid pipe 15 on the lower surface of the floating block 32 will be affected. That is, the hypochlorous acid water discharged from the outlet pipe 12 will stop or the hypochlorous acid water will be discharged intermittently, thereby indicating the movement status and relative position of the floating block 32 in the pressure tank 3.

[0114] Simultaneously, when the disinfection device is stopped and the remaining hypochlorous acid water in pressure tank 3 needs to be drained, close the valves on the inlet pipe 11, pure water pipe 13, and air inlet pipe 16. Then, inject gas through the air inlet pipe 16 to increase the pressure in the space between the floating block 32 and the sealing cover 31. This causes the floating block 32 to move downward under pressure, squeezing the remaining hypochlorous acid water in pressure tank 3 and causing it to be discharged through the elastic liquid pipe 15 and the outlet pipe 12. Afterward, close the valve on the air inlet pipe 16 and open the valve on the exhaust pipe 17, drawing the water out through the exhaust pipe 17. The gas reduces the pressure in the space between the floating block 32 and the closed cover 31, causing the floating block 32 to move upward under pressure. Then, the water outlet pipe 12 is closed and the pure water pipe 13 is opened, allowing pure water to flow back into the elastic liquid pipe 15 and then sprayed into the pressure tank 3 to clean the residual hypochlorous acid water on the inner wall of the pressure tank 3. After that, the pure water pipe 13 and the exhaust pipe 17 are closed again, and the water outlet pipe 12 and the air inlet pipe 16 are opened. Gas is injected from the air inlet pipe 16, causing the floating block 32 to move downward and discharge the water left in the pressure tank 3 after cleaning.

[0115] When the purified water enters the elastic fluid tube 15 in the reverse direction, the purified water will impact the movable plate 35 at the outlet of the elastic fluid tube 15, causing the movable plate 35 and the slide rod 351 to move downward until the slide rod 351 is fully extended and the movable plate 35 reaches the outside of the outlet of the elastic fluid tube 15. At this time, after the purified water is sprayed out from the outlet of the elastic fluid tube 15 in the reverse direction, the purified water will impact the movable plate 35, so that the purified water is guided and directed by the surface of the movable plate 35 and flushed towards the inner wall surface of the pressure tank 3, thus flushing and cleaning the inner wall of the pressure tank 3.

[0116] Because the movable plate 35 is umbrella-shaped and its convex surface faces the bottom of the pressure tank 3, after the pure water is sprayed out from the outlet of the elastic liquid pipe 15 in the opposite direction, the pure water will be affected by the arc surface on the movable plate 35 and spray out in the opposite direction at an angle upward, rinsing the lower surface of the floating block 32. At the same time, after the pure water impacts the lower surface of the floating block 32, it will be guided by the lower surface of the floating block 32, so that the sprayed pure water contacts the angle and turning point between the floating block 32 and the inner wall of the storage tank, avoiding dead corners and angles between the floating block 32 and the inner wall of the storage tank, which would result in the presence of hypochlorous acid water residue.

[0117] When the floating block 32 moves downward to the lower part of the pressure tank 3, the bonding layer 34 on the lower surface of the floating block 32 comes into contact with the bottom surface of the pressure tank 3 to avoid gaps, which would result in residual hypochlorous acid water and poor disinfection and sterilization effect in the initial period of use.

[0118] Since the thickness at the upper edge of the bonding layer 34 is greater than that at the middle position, when the floating block 32 moves downward, the edge of the bonding layer 34 will first contact the bottom surface of the pressure tank 3. Then, as the floating block 32 descends, the edge of the bonding layer 34 will be squeezed and undergo elastic deformation. During this process, the hypochlorous acid water present at the bottom surface of the pressure tank 3 is guided and accumulated by the lower surface of the bonding layer 34, which facilitates the absorption of the remaining hypochlorous acid water by the outlet of the elastic liquid tube 15 located at the middle position of the lower surface of the floating block 32.

[0119] When the remaining hypochlorous acid water needs to be drained from the disinfection device after use, open the valve on the pure water pipe 13 and close the valves on the outlet pipe 12 and inlet pipe 11. This allows pure water to flow back into the space containing hypochlorous acid water in the constant temperature module 2 through the transfer in the pressure tank 3, and the elastic bladder 41 to fully expand in the buffer tank 4. Then, close the valve on the pure water pipe 13 and vent air outward from the exhaust pipe 17, causing the floating block 32 to move upward under pressure. This draws the liquid from the elastic bladder 41, water tank 23, and connecting pipe 14 into the pressure tank 3. After draining the liquid from the pressure tank 3, repeat the above operation several times to thoroughly rinse and clean the constant temperature module 2, connecting pipe 14, and pressure tank 3, preventing corrosion of the disinfection device and ensuring that the sterilization performance of the hypochlorous acid water output is not good during the initial period of use.
