Description

Technical Field

[0001] This invention relates to the field of ozone disinfection equipment technology, specifically to ozone disinfection equipment and its control method. Background Technology

[0002] Currently available ozone disinfection equipment uses electrolysis to convert tap water into ozone water with sterilization and disinfection functions. The ozone water generator is the core component of the ozone disinfection equipment and is expensive. If used improperly, it can easily run dry, meaning it operates without water, which not only poses a significant safety hazard but also degrades or damages the ozone generator's performance, severely affecting its lifespan and increasing operating costs. Summary of the Invention

[0003] In view of this, the present invention provides an ozone disinfection device and its control method to solve the problem that the ozone water generator in the prior art is prone to dry burning.

[0004] In a first aspect, the present invention provides an ozone disinfection device, comprising:

[0005] Water tank;

[0006] An ozone generator includes an anti-dry-burning chamber connected to a water tank, an ozone generator and a liquid level detection mechanism installed in the anti-dry-burning chamber, wherein the water tank can selectively fill the anti-dry-burning chamber with water, and the liquid level detection mechanism is used to detect the liquid level information in the anti-dry-burning chamber.

[0007] The controller is connected to both the ozone generator and the liquid level detection mechanism. The controller is adapted to control the operation of the ozone generator based on the liquid level information detected by the liquid level detection mechanism.

[0008] Beneficial effects: The ozone generator will only start when the liquid level detection mechanism detects that the liquid level in the anti-dry-burning chamber is greater than or equal to the preset anti-dry-burning water level. Otherwise, water will continue to be added to the anti-dry-burning chamber until the liquid level reaches the anti-dry-burning water level. This effectively prevents the ozone generator from operating directly without water or with insufficient water, thus avoiding dry burning. This improves the safety and lifespan of the ozone disinfection equipment and effectively solves the problem of dry burning caused by improper use of the ozone generator in existing ozone disinfection equipment, which poses a significant safety hazard, reduces or damages the performance of the ozone generator, seriously affects the lifespan of the ozone water generator, and increases the cost of use.

[0009] In one optional embodiment, the ozone disinfection device further includes:

[0010] The air blowing device has its air outlet connected to the anti-dry-burning chamber, and is suitable for blowing air into the anti-dry-burning chamber to dry the ozone generator.

[0011] Beneficial effects: The blowing device can blow air into the anti-dry-burning chamber to dry the ozone generator when the ozone disinfection equipment is not in use. This prevents mold growth, odor, or bacterial growth in the anti-dry-burning chamber due to prolonged disuse of the ozone disinfection equipment, which would affect the hygienic quality of the prepared disinfectant and the service life of the ozone generator.

[0012] In one alternative embodiment, the blowing device includes:

[0013] The fan assembly has its air inlet connected to the external environment of the ozone disinfection equipment and its air outlet connected to the anti-dry-burning chamber, which is suitable for driving air from the external environment into the anti-dry-burning chamber.

[0014] The heating element, located in the fan assembly, is suitable for heating air to dry the ozone generator using hot air.

[0015] Beneficial effects: The heating element can heat the air blown into the anti-dry-burning chamber, and use the hot air to dry the ozone generator, resulting in better efficiency and dehumidification.

[0016] In one alternative implementation, the wind turbine assembly includes:

[0017] The fan casing has an air inlet and an air outlet;

[0018] The fan is installed inside the fan casing;

[0019] The air inlet duct connects the air inlet to the external environment, and the air outlet duct connects the air outlet to the anti-dry-burning chamber.

[0020] The heating element is located inside the fan casing, in the air inlet duct, or in the air outlet duct.

[0021] In one alternative implementation, the water tank and the anti-dry-burning chamber are connected by a water inlet pipe, and a first valve is provided on the water inlet pipe.

[0022] Beneficial effect: By controlling the opening and closing of the water inlet pipe through the first valve, it is possible to control whether water enters the anti-dry burning chamber from the water tank.

[0023] In one alternative embodiment, the first valve is a three-way valve with three valve ports, one of which is connected to the air outlet pipe of the blower, and the other two valve ports are connected to the water inlet pipe.

[0024] The first valve is adapted to switch between a first state in which the water tank and the anti-dry-burning chamber are connected and the air blowing device and the anti-dry-burning chamber are blocked, and a second state in which the air blowing device and the anti-dry-burning chamber are connected and the water tank and the anti-dry-burning chamber are blocked.

[0025] Beneficial effects: During the normal disinfection process, the controller switches the first valve to connect the water tank and the anti-dry-burning chamber, allowing water to enter the chamber. When the drying process is required, the controller switches the first valve to connect the air blower to the anti-dry-burning chamber, allowing air to be blown into the chamber and ozone generator to dry them and prevent mold growth. The three-way valve design enables rapid switching between the air blower and the water tank, as well as between the water tank and the anti-dry-burning chamber, allowing for more efficient switching between disinfection and drying processes. The design is also simpler, more reliable, and simplifies the number of pipes and valves, saving costs.

[0026] In one alternative implementation, a check valve is provided on the air outlet duct;

[0027] Alternatively, a check valve or a non-return valve may be installed on the water inlet pipe between the first valve and the anti-dry-burning chamber.

[0028] Beneficial effects: The check valve effectively prevents water in the anti-dry-burning chamber from flowing back into the fan and damaging it. The one-way valve is configured to restrict the flow of water from the water tank to the anti-dry-burning chamber, thus effectively preventing water in the anti-dry-burning chamber from flowing back into the fan and damaging it.

[0029] In one optional embodiment, the ozone generator further includes a nozzle, the inlet end of the ozone generator is connected to the anti-dry-burning chamber, the outlet end is connected to the nozzle, and the air outlet pipe of the blowing device is connected to the nozzle through a connecting pipe.

[0030] The first valve is a two-position four-way valve with four valve ports. One valve port is connected to the air outlet pipe, one valve port is connected to the connecting pipe, and the other two valve ports are connected to the water inlet pipe.

[0031] The first valve is adapted to switch between a third state, in which the water tank and the anti-dry-burning chamber are connected and the air blowing device and the nozzle are blocked, and a fourth state, in which the air blowing device and the nozzle are connected and the water tank and the anti-dry-burning chamber are blocked.

[0032] Beneficial effects: When the first valve is in the fourth state, the air blown out by the blowing device can not only blow into the anti-dry burning chamber, but also into the nozzle, thereby achieving simultaneous drying of the nozzle and the anti-dry burning chamber, effectively preventing mold growth in the nozzle and the anti-dry burning chamber, and further improving the hygiene and quality of the prepared ozone disinfectant.

[0033] In one alternative embodiment, the nozzle includes a nozzle body, a jet pipe connected between the nozzle body and the ozone generator, and a jet valve disposed on the jet pipe.

[0034] Beneficial effects: By installing a spray valve on the spray pipeline, the opening and closing of the spray head can be controlled. The spray valve will not open when the spray head does not receive an electrical signal, so that the prepared disinfectant is sprayed outside the equipment.

[0035] In one optional embodiment, the ozone disinfection device further includes:

[0036] The timing device, connected to the controller, is suitable for recording the interval T between the ozone generator and the end of the last disinfection program, and for sending a timeout signal to the controller when it is determined that the interval T is greater than the preset interval T1.

[0037] Beneficial effects: Since the ozone disinfection equipment may be used again immediately after the disinfection process ends, this embodiment can calculate the interval between the last operation of the ozone generator and the current operation by setting a timing device, and when it is determined that the interval is greater than the preset interval, it feeds back the time signal to the control, so as to facilitate the control of the start time of the drying process.

[0038] In one optional embodiment, the bottom of the anti-dry-burning chamber is provided with a drain outlet, and a drain pipe is connected to the drain outlet, with a second valve installed on the drain pipe.

[0039] Beneficial effects: The second valve allows for easy control of the discharge of residual water from the anti-dry-burning chamber, preventing residual water from accumulating in the chamber for a long time and causing mold or rust on the ozone generator or liquid level detection mechanism.

[0040] In one optional embodiment, a water level detection mechanism is provided inside the water tank, which is used to detect the water level information inside the water tank.

[0041] Beneficial effects: By using a water level detection mechanism to monitor the water level in the tank, the problem of insufficient water level affecting the use of the water tank can be avoided.

[0042] In one alternative embodiment, the ozone disinfection device further includes a water replenishment mechanism for introducing water into the water tank.

[0043] Beneficial effects: By setting up a water replenishment mechanism, when the water level in the water tank is lower than the preset water level, the water replenishment mechanism will be activated to automatically add water to the water tank, so as to ensure that the ozone disinfection equipment can properly prepare ozone disinfection solution.

[0044] Secondly, the present invention also provides a control method for an ozone disinfection device, the control method being applicable to the ozone disinfection device of any of the above embodiments, the control method comprising:

[0045] Receive the instruction to start the disinfection process;

[0046] Control the water tank to supply water to the anti-dry-burning chamber;

[0047] The liquid level information in the anti-dry-burning chamber is obtained in real time, and it is determined whether the liquid level information is greater than or equal to the preset anti-dry-burning water level.

[0048] If yes, then control the ozone generator to start; if no, control the ozone generator to remain off until the liquid level information is detected to reach the preset anti-dry-burning water level, then control the ozone generator to start.

[0049] In one optional implementation, after the disinfection procedure is completed, the following steps are also performed:

[0050] Receive the command to start the drying process;

[0051] Open the drain pipe of the ozone generator to drain the liquid inside the ozone generator;

[0052] The blower is activated to blow air into the anti-dry-burning chamber to dry the ozone generator.

[0053] In one optional implementation, the blowing device is activated to blow air into the anti-dry-burning chamber to dry the ozone generator, specifically including:

[0054] The system controls the start-up of heating components and fan assemblies, using hot air to dry the ozone generator.

[0055] In one optional implementation, receiving the instruction to start the drying process specifically includes:

[0056] When the timing device determines that the interval T between the ozone generator and the end of the last disinfection program is greater than the preset interval T1, it sends a timeout signal to the controller.

[0057] When the controller receives the time signal, it controls the ozone disinfection equipment to start the drying process.

[0058] In one alternative implementation, the following steps are performed before the blower is activated:

[0059] Obtain the liquid level information inside the anti-dry-burning chamber;

[0060] If the liquid level in the anti-dry-burning chamber is lower than the preset drainage level, the blower is activated; otherwise, drainage continues.

[0061] In one alternative implementation, the following steps are performed before water is introduced into the anti-dry-burning chamber from the water tank:

[0062] Obtain water level information in the water tank;

[0063] When it is determined that the water level in the water tank does not meet the preset working conditions, the water replenishment mechanism is controlled to add water to the water tank and the user is notified.

[0064] When the water level in the tank is determined to meet the preset working conditions, the water tank is connected to the anti-dry-burning chamber, and water is introduced into the anti-dry-burning chamber. Attached Figure Description

[0083] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0084] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0085] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0086] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0087] Currently available ozone disinfection equipment uses electrolysis to convert tap water into ozone water with sterilization and disinfection functions. The ozone water generator is the core component of the ozone disinfection equipment and is expensive. If used improperly, it can easily run dry, meaning it operates without water, which not only poses a significant safety hazard but also degrades or damages the ozone generator's performance, severely affecting its lifespan and increasing operating costs.

[0088] In addition, the water source for ozone disinfection equipment is tap water. If it is not used for a long time, the residual microorganisms or insect eggs in the tap water will mold, produce odors or breed bacteria, which will not only affect the sanitary quality of the prepared disinfectant water, but also affect the lifespan of the ozone water generator.

[0089] However, most ozone disinfection devices on the market provide reminders to users in their instructions, but users often do not pay attention to or ignore these reminders, which can still lead to dry burning or mold growth, thus affecting the lifespan of the ozone generator. Therefore, there is a need for an ozone disinfection device that can effectively prevent dry burning and mold growth in ozone generators.

[0090] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0091] According to embodiments of the present invention, in one aspect, the present invention provides an ozone disinfection device, such as... Figures 1 to 4 As shown, the ozone disinfection equipment includes: a water tank 10, an ozone generator 20, and a controller 30. The ozone generator 20 includes an anti-dry-burning chamber 21 connected to the water tank 10, an ozone generator 22, and a liquid level detection mechanism 23 disposed in the anti-dry-burning chamber 21. The water tank 10 can selectively fill the anti-dry-burning chamber 21 with water. The liquid level detection mechanism 23 is used to detect the liquid level information in the anti-dry-burning chamber 21. The controller 30 is connected to the ozone generator 22 and the liquid level detection mechanism 23 respectively. The controller 30 is adapted to control the operation of the ozone generator 22 according to the liquid level information detected by the liquid level detection mechanism 23.

[0092] In the above embodiment, the ozone generator 22 will only be started when the liquid level detection mechanism 23 detects that the liquid level in the anti-dry-burning chamber 21 is greater than or equal to the preset anti-dry-burning water level. Otherwise, water will continue to be introduced into the anti-dry-burning chamber 21 until the liquid level is detected to reach the anti-dry-burning water level. This effectively prevents the ozone generator 22 from working directly without water or with insufficient water, thus avoiding dry burning. This improves the safety and lifespan of the ozone disinfection equipment and effectively solves the problem of dry burning caused by improper use of the ozone generator 22 in existing ozone disinfection equipment, which poses a significant safety hazard, reduces or damages the performance of the ozone generator 22, seriously affects the lifespan of the ozone water generator, and increases the cost of use.

[0093] It should be noted that in this embodiment, "the controller 30 is adapted to control the operation of the ozone generator 22 according to the liquid level information detected by the liquid level detection mechanism 23" specifically includes: when the liquid level information detected by the liquid level detection mechanism 23 is greater than or equal to the preset anti-dry burning water level, the controller 30 controls the ozone generator 22 to work; when the liquid level information detected by the liquid level detection mechanism 23 is less than the preset anti-dry burning water level, the controller 30 controls the ozone generator 22 not to work.

[0094] In some embodiments, the anti-dry-burning water level is greater than the maximum height of the ozone generator 22 inlet end, thereby ensuring that the ozone generator 22 is in the optimal full-load working state, thereby achieving the purpose of saving energy consumption and avoiding the problem of resource waste.

[0095] Furthermore, in this embodiment, the ozone disinfection equipment also includes a housing 100, with the water tank 10 and ozone generator 20 all disposed within the housing 100. The anti-dry-burning chamber 21 is composed of a hollow shell, and the ozone generator 22 is disposed within this shell, i.e., within the anti-dry-burning chamber 21.

[0096] Optionally, the housing of the anti-dry-burning chamber 21 is provided with a disassembly port, and a cover is provided at the disassembly port that can be opened and closed, so that the ozone generator 22 can be easily disassembled and assembled through the disassembly port.

[0097] Preferably, the disassembly port is provided corresponding to the ozone generator 22 and is located at the top of the housing, and a sealing structure is provided between the disassembly port and the cover.

[0098] In this embodiment, the liquid level detection mechanism 23 is installed inside the anti-dry-burning chamber 21 to detect the water level height information inside the anti-dry-burning chamber 21. The ozone generator 22 can electrolyze water to generate ozone water with disinfection function. The controller 30 can control whether the ozone generator 22 works and whether water enters the anti-dry-burning chamber 21 according to the water level height information detected by the liquid level detection mechanism 23, so as to avoid the ozone generator 22 from dry burning.

[0099] In some embodiments, the ozone disinfection device further includes a blower 40, the air outlet of which is connected to the anti-dry-burning chamber 21 and is adapted to blow air into the anti-dry-burning chamber 21 to dry the ozone generator 20.

[0100] In the above embodiment, the blowing device 40 can blow air into the anti-dry burning chamber 21 to dry the ozone generator 20 when the ozone disinfection equipment is not in use. This prevents the ozone disinfection equipment from being left unused for a long time, which could cause mold to grow in the anti-dry burning chamber 21, produce odors, or breed bacteria, affecting the hygienic quality of the prepared disinfectant water and the service life of the ozone generator 22.

[0101] In some embodiments, the blowing device 40 includes a fan assembly 41 and a heating element 42, wherein the air inlet of the heating element is connected to the external environment of the ozone disinfection device, and the air outlet is connected to the anti-dry-burning chamber 21, and is adapted to drive air from the external environment into the anti-dry-burning chamber 21; the heating element 42 is disposed on the fan assembly 41 and is adapted to heat the air so as to dry the ozone generator 20 with hot air.

[0102] In the above embodiment, the heating element 42 can heat the air blown into the anti-dry burning chamber 21, and use hot air to dry the ozone generator 20, which is more efficient and has a better dehumidification effect.

[0103] In some alternative embodiments, the blower 40 may also include only the blower assembly 41 without the heating element 42, which simplifies the structure and saves production costs.

[0104] In some alternative embodiments, the blowing device 40 may also use an airflow drive such as a fan to generate airflow and blow air into the anti-dry burning chamber 21.

[0105] In some specific embodiments, the fan assembly 41 includes a fan housing 100, a fan, an air inlet duct 401, and an air outlet duct 402. The fan housing 100 has an air inlet and an air outlet. The fan is disposed inside the fan housing 100. The air inlet duct 401 connects the air inlet and the external environment, and the air outlet duct 402 connects the air outlet and the anti-dry-burning chamber 21. The heating element 42 is disposed inside the fan housing 100, on the air inlet duct 401, or on the air outlet duct 402.

[0106] In the above embodiments, by placing the heating element 42 inside the fan housing 100, on the air inlet pipe 401, or on the air outlet pipe 402, the air entering the anti-dry-burning chamber 21 can be heated.

[0107] Preferably, the heating element 42 is disposed on the air inlet duct 401.

[0108] Furthermore, the heating element 42 is a heating tube or an electric heating wire. This embodiment does not limit the specific structure of the heating element 42.

[0109] Furthermore, an air inlet is provided on the housing 100, which is connected to the air inlet pipe 401 to introduce air into the blower 40. At the same time, the air inlet pipe 401 is connected to the heating element 42 and the fan assembly 41. The heating element 42 is connected to the air inlet to heat the air, and the fan assembly 41 guides the heated air into the anti-dry burning chamber 21.

[0110] In some embodiments, the water tank 10 and the anti-dry-burning chamber 21 are connected by a water inlet pipe 101, and a first valve 1011 is provided on the water inlet pipe 101.

[0111] In the above embodiment, the opening and closing of the water inlet pipe 101 is controlled by the first valve 1011, thereby enabling control of whether the water tank 10 enters the anti-dry burning chamber 21.

[0112] It should be noted that the first valve 1011 is a solenoid valve, which improves the automation and intelligence of the entire equipment.

[0113] Combination Figure 1 and Figure 2 As shown, in the first embodiment, the first valve 1011 is a three-way valve with three valve ports, one of which is connected to the air outlet pipe 402 of the blower 40, and the other two valve ports are connected to the water inlet pipe 101; the first valve 1011 is adapted to switch between a first state of connecting the water tank 10 and the anti-dry-burning chamber 21 and blocking the blower 40 and the anti-dry-burning chamber 21, and a second state of connecting the blower 40 and the anti-dry-burning chamber 21 and blocking the water tank 10 and the anti-dry-burning chamber 21.

[0114] In the above embodiment, when the disinfection process is in progress, the controller 30 controls the first valve 1011 to switch to the state where the water tank 10 is connected to the anti-dry-burning chamber 21, and controls the water tank 10 to enter the anti-dry-burning chamber 21. When the drying process is required, the controller 30 controls the first valve 1011 to switch to the state where the blower 40 is connected to the anti-dry-burning chamber 21, and the blower 40 blows air into the anti-dry-burning chamber 21 to dry the anti-dry-burning chamber 21 and ozone generator 22 and other components to prevent mold growth. By adopting the three-way valve design, the blower 40 and the water tank 10, as well as the water tank 10 and the anti-dry-burning chamber 21, can be quickly switched and connected. This can achieve more efficient switching between the disinfection process and the drying process, and the structure is simpler and more reliable. It can also simplify the number of pipes and valves and save costs.

[0115] Of course, in other alternative embodiments, the air outlet duct 402 of the blower 40 can also be connected to the anti-dry-burning chamber 21 through a separate duct and valve.

[0116] In some embodiments, a check valve is provided on the air outlet duct 402. The check valve can effectively prevent water in the anti-dry-burning chamber 21 from flowing back into the fan and damaging the fan.

[0117] In some alternative embodiments, a one-way valve or a check valve is provided on the water inlet pipe 101 between the first valve 1011 and the anti-dry-burning chamber 21.

[0118] In the above embodiment, the one-way valve is configured to restrict the one-way flow of water from the water tank 10 to the anti-dry-burning chamber 21, thereby effectively preventing water in the anti-dry-burning chamber from flowing back into the fan and damaging the fan.

[0119] Combination Figure 3 and Figure 4 As shown, in the second embodiment, the ozone generator 20 further includes a nozzle 24, which sprays ozone water to the outside of the machine for disinfection. The inlet end of the ozone generator 22 is connected to the anti-dry-burning chamber 21, and the outlet end is connected to the nozzle 24. The air outlet pipe 402 is connected to the nozzle 24 through a connecting pipe 202. The first valve 1011 is a two-position four-way valve with four valve ports. One valve port is connected to the air outlet pipe 402 of the blowing device 40, one valve port is connected to the connecting pipe 202, and the other two valve ports are connected to the water inlet pipe 101. The first valve 1011 is adapted to switch between a third state of connecting the water tank 10 and the anti-dry-burning chamber 21 and blocking the blowing device 40 and the nozzle 24, and a fourth state of connecting the blowing device 40 and the nozzle 24 and blocking the water tank 10 and the anti-dry-burning chamber 21.

[0120] In the above embodiment, when the first valve 1011 is in the fourth state, the air blown out by the blowing device 40 can not only blow into the anti-dry burning chamber 21, but also into the nozzle 24, thereby achieving simultaneous drying of the nozzle 24 and the anti-dry burning chamber 21, effectively preventing mold growth in the nozzle 24 and the anti-dry burning chamber 21, and further improving the hygiene and quality of the prepared ozone disinfectant.

[0121] Furthermore, in this embodiment, the air outlet pipe 402 and the nozzle 24 are connected by the connecting pipe 202. During the drying process, the first valve 1011 is switched to a state where the air blowing device 40 and the nozzle 24 are connected, and the water tank 10 and the anti-dry burning chamber 21 are blocked. This allows the air from the air blowing device 40 to be discharged from the nozzle 24 to dry the nozzle 24, and to enter the anti-dry burning chamber 21 in reverse to dry the anti-dry burning chamber 21 and its internal ozone generator 22. The air will not flow through the water outlet pipe, which can effectively prevent the water in the anti-dry burning chamber 21 from flowing back into the fan assembly 41.

[0122] In some embodiments, the nozzle 24 includes a nozzle body, a jet pipe 241 connected between the nozzle body and the ozone generator 22, and a jet valve disposed on the jet pipe 241.

[0123] In the above embodiments, the spray valve provided on the spray pipe 241 can control the opening and closing of the spray head 24. When the spray head 24 does not receive an electrical signal, the spray valve will not open, thus ensuring that the prepared disinfectant is sprayed outside the equipment. In some embodiments, the connecting pipe 202 is connected to the spray pipe.

[0124] Of course, in other alternative implementations, the jet valve can also be located at the nozzle of the nozzle 24 to control the opening and closing of the nozzle 24.

[0125] In some embodiments, the ozone disinfection device further includes a timing device 50, which is connected to the controller 30 and is adapted to record the interval T between the ozone generator 22 and the end of the last disinfection program, and to send a time signal to the controller 30 when it is determined that the interval T is greater than the preset interval T1.

[0126] In the above embodiment, since the ozone disinfection equipment may be used again right after the disinfection process ends, this embodiment can calculate the interval time from the last operation of the ozone generator 20 to the present by setting the timing device 50, and when it is determined that the interval time is greater than the preset interval time, it feeds back the time signal to the control, so as to facilitate the control of the start time of the drying process.

[0127] Optionally, the timing device 50 includes an electronic timer, a timer clock, a timing sensor, etc. The controller 30 obtains the time point at which the ozone disinfection equipment ends its operation based on the opening and closing information of the ozone generator 22 or the spray valve, and controls the timing device 50 to start timing.

[0128] In some embodiments, the bottom of the anti-dry-burning chamber 21 is provided with a drain outlet, and a drain pipe 201 is connected to the drain outlet. A second valve 2011 is provided on the drain pipe 201. The second valve 2011 facilitates the discharge of residual water in the anti-dry-burning chamber 21, preventing residual water from accumulating in the anti-dry-burning chamber 21 for a long time and causing mold or rust on the ozone generator 22 or the liquid level detection mechanism 23.

[0129] In the above embodiment, the second valve 2011 is a drain solenoid valve connected to the controller 30. The controller 30 controls the opening and closing of the drain pipeline 201 by controlling the drain solenoid valve to be energized or de-energized.

[0130] In some embodiments, a water level detection mechanism 11 is provided inside the water tank 10. The water level detection mechanism 11 is used to detect the water level information inside the water tank 10. By monitoring the water level information inside the water tank 10 through the water level detection mechanism 11, the phenomenon of insufficient water level in the water tank 10 affecting its use is avoided.

[0131] Optionally, the water level detection mechanism 11 is a water level sensor installed inside the water tank 10, used to detect the water level information inside the water tank 10.

[0132] In some embodiments, the ozone disinfection equipment further includes a water replenishment mechanism 12 for supplying water to the water tank 10. When the water level in the water tank 10 is lower than a preset level, the water replenishment mechanism 12 is activated to automatically supply water to the water tank 10, ensuring that the ozone disinfection equipment can properly prepare ozone disinfectant.

[0133] Specifically, the water replenishment mechanism 12 includes a water replenishment pipe 121 connecting the faucet and the water inlet of the water tank 10, and a water replenishment valve 1211 disposed on the water replenishment pipe 121. The water replenishment pipe 121 is mounted on the housing 100 and connected to the water tank 10 for replenishing water, and the water replenishment valve 1211 is disposed on the water replenishment pipe 121 for controlling whether water is replenished.

[0134] In some embodiments, the ozone disinfection equipment further includes a display device 60, which is mounted on the housing 100 and is used to display the working status and prompts of the ozone disinfection equipment.

[0135] Optionally, in this embodiment, the controller 30 includes a control board mounted on the housing 100. The control board is used to connect electrical components in the device and transmit control signals.

[0136] It should be noted that all gas and water circuits of the ozone disinfection equipment provided in this embodiment are threaded or sealed with adhesive, while other non-water and gas circuit components are fixed by screws or clips.

[0137] Preferably, the ozone disinfection equipment in this embodiment is a disinfectant manufacturing machine.

[0138] The ozone disinfection equipment provided in this embodiment can effectively prevent the ozone generator 22 from dry burning and mold growth. The machine is automatically controlled to ensure its lifespan and improve the user experience.

[0139] According to an embodiment of the present invention, in another aspect, a control method for an ozone disinfection device is provided. This control method is applicable to the ozone disinfection device of any of the above embodiments, and is combined with... Figures 1 to 5 As shown, the control method includes the following steps:

[0140] Step S101: Receive the instruction to start the disinfection program;

[0141] Step S102: Control the water tank 10 to supply water to the anti-dry-burning chamber 21;

[0142] Step S103: Obtain the liquid level information in the anti-dry-burning chamber 21 in real time, and determine whether the liquid level information is greater than or equal to the preset anti-dry-burning water level;

[0143] If yes, proceed to step S104; if no, proceed to step S105.

[0144] Step S104: Control ozone generator 22 to start;

[0145] Step S105: Keep the ozone generator 22 off until the liquid level information is detected to reach the preset anti-dry burning water level, then control the ozone generator 22 to start.

[0146] In the above embodiment, when the liquid level detection mechanism 23 detects that the liquid level in the anti-dry-burning chamber 21 is less than the preset anti-dry-burning water level, it controls the ozone generator 22 not to start. Only when the water level reaches the preset anti-dry-burning water level will the ozone generator 22 be controlled to start, effectively avoiding the phenomenon of dry burning of the ozone generator 22 due to insufficient water flow.

[0147] In some embodiments, combined with Figures 1 to 4 as well as Figure 6 As shown, after the disinfection procedure is completed, the following steps are also performed:

[0148] Step S201: Receive the instruction to start the drying process;

[0149] Step S202: Control the opening of the drain pipe 201 of the ozone generator 20 to drain the liquid inside the ozone generator 20;

[0150] Step S203: Control the start of the blowing device 40 to blow air into the anti-dry burning chamber 21 to dry the ozone generator 20.

[0151] In the above embodiment, the drying process can be started according to the user's trigger command or the time signal detected by the timing device 50. During the drying process, the drain pipe 201 of the ozone generator 20 is opened to drain the liquid in the ozone generator 20. Then, the blower 40 is started to blow air into the anti-dry burning chamber 21, which facilitates rapid dehumidification and drying, and the drying efficiency is higher.

[0152] The ozone disinfection equipment provided in this embodiment, by adopting the above-mentioned control method, can effectively prevent the ozone generator 22 from dry burning and mold growth compared with ordinary ozone disinfection equipment, thereby improving the service life of the ozone disinfection equipment. Moreover, the machine is automatically controlled, with a higher degree of intelligence and automation, resulting in a better user experience.

[0153] Preferably, in step S202, while controlling the opening of the drain pipe 201 of the ozone generator 20, the spray valve is also controlled to open, so that the residual water in the nozzle 24 is also discharged, which improves the anti-mold effect.

[0154] In some embodiments, the blowing device 40 is activated to blow air into the anti-dry-burning chamber 21 to dry the ozone generator 20, specifically including the following steps:

[0155] The heating element 42 and the fan assembly 41 are activated to dry the ozone generator 20 with hot air. Drying the ozone generator 20 with hot air improves the dehumidification and mold prevention effects.

[0156] In some embodiments, combined with Figures 1 to 4 as well as Figure 7As shown, receiving the instruction to start the drying process specifically includes:

[0157] Step S301: When the timing device 50 determines that the interval T between the ozone generator 22 and the end of the last disinfection program is greater than the preset interval T1, it sends a timeout signal to the controller 30.

[0158] Step S302: When the controller 30 receives the time signal, it controls the ozone disinfection equipment to start the drying program.

[0159] In the above embodiment, the timing device 50 calculates the interval time between the last operation of the ozone generator 22. When it is determined that the interval time is greater than the preset interval time T1, the controller 30 will automatically control the ozone disinfection equipment to start the air drying program to prevent the ozone disinfection equipment from not working for a long time, and prevent residual water in the anti-dry burning chamber 21 and the ozone generator 22 or the nozzle 24 from becoming moldy and breeding bacteria.

[0160] In some embodiments, combined with Figures 1 to 4 as well as Figure 8 As shown, before starting the blower 40, the following steps are performed:

[0161] Step S401: Obtain the liquid level information in the anti-dry-burning chamber 21;

[0162] Step S402: Determine whether the liquid level in the anti-dry burning chamber 21 is lower than the preset drainage level; if yes, proceed to step S403; if no, proceed to step S404.

[0163] Step S403: Start the blower device 40;

[0164] Step S404: Continue draining.

[0165] In some embodiments, combined with Figures 1 to 4 as well as Figure 9 As shown, the following steps are performed before water is introduced into the anti-dry-burning chamber 21 from the water tank 10:

[0166] Step S501: Obtain the water level information in water tank 10;

[0167] Step S502: When it is determined that the water level information in the water tank 10 does not meet the preset working conditions, the water replenishment mechanism 12 is controlled to add water to the water tank 10 and the user is notified.

[0168] Step S503: When it is determined that the water level information in the water tank 10 meets the preset working conditions, the water tank 10 is connected to the anti-dry-burning chamber 21, and water is introduced into the anti-dry-burning chamber 21.

[0169] In the above embodiment, before the ozone generator 20 starts working, it is first determined whether the water level in the water tank 10 meets the preset working conditions. If it does not meet the conditions, the water replenishment mechanism 12 is controlled to add water to the water tank 10 to avoid insufficient water in the water tank 10. Adding water midway will affect the preparation efficiency of the disinfectant water, and also to avoid insufficient water causing the ozone generator 22 to dry burn.

[0170] Preferably, the preset working condition is that the water level in the water tank 10 reaches the preset working water level.

[0171] The following is combined with Figures 1 to 9 The structure and working process of the ozone disinfection equipment in this embodiment are described.

[0172] When the machine is running, the water level detection mechanism 11 will detect the liquid level in the water tank 10. If the liquid level does not meet the preset working conditions, the machine will control the replenishment of water until the liquid level meets the working conditions.

[0173] When the liquid level meets the operating requirements, the machine controls the first valve 1011 to connect the water tank 10 to the anti-dry-burning chamber 21 and disconnect the blower 40 from the nozzle 24 or the anti-dry-burning chamber 21. At this time, the second valve 2011 on the drain pipe 201 of the anti-dry-burning chamber 21 is closed (the second valve 2011 is normally closed). The tap water in the water tank 10 flows into the anti-dry-burning chamber 21. At this time, the ozone generator 22 is not in working condition, and the tap water will not flow out of the ozone generator 22 because the ozone generator 22 is equipped with a waterproof and breathable membrane or molecular sieve, which allows gas to pass through but not liquid. The water level in the anti-dry-burning chamber 21 rises until the liquid level detection mechanism 23 detects that the water level in the anti-dry-burning chamber 21 has reached the preset anti-dry-burning water level. Only then will the ozone generator 22 work normally. Through the above methods, the ozone generator 22 can be effectively prevented from dry-burning.

[0174] In this embodiment, the disinfectant in the nozzle 24 will not normally spray out; the nozzle 24 will only open and spray when an instruction is received. When the ozone generator 22 is working normally, it sprays ozone water, which is sufficient for disinfection.

[0175] When the equipment is not used for a long period of time, the timing device 50 will record the interval T between the last working distance of the nozzle 24's spray valve or the ozone water generator and the current time. When the machine detects that T>T1 (the preset interval time), the controller 30 will switch the working state of the first valve 1011, connecting the air supply to the nozzle 24 or the anti-dry-burning chamber 21, and disconnecting the water tank 10 from the anti-dry-burning chamber 21. Then, it will control the second valve 2011 to open, draining the liquid in the second valve 2011 and the anti-dry-burning chamber 21. At the same time, the nozzle 24 will open synchronously, draining the liquid in the nozzle 24 and the pipeline.

[0176] When the liquid level in the anti-dry-burning chamber 21 falls below the preset drainage level, the controller 30 activates the heating element 42 and the fan assembly 41 to blow hot air onto the anti-dry-burning chamber 21 and the ozone generator 22 for drying. The drying time is preset by the machine; after the preset time, the machine stops working, and the anti-dry-burning chamber 21 and the ozone generator 22 remove moisture. This process prevents mold growth. The device then enters standby mode and requires manual unlocking to resume operation.

[0177] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
