Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a disinfection device, a control method for the disinfection device, and a storage medium. Background Technology

[0002] In related technologies, hypochlorous acid is an oxidizing gas commonly used as a disinfectant. Disinfection machines achieve their disinfection effect by preparing hypochlorous acid and releasing it into the air. If the wastewater containing hypochlorous acid is not discharged after each use, the hypochlorous acid will be re-prepared for the next use, leading to an increasingly high concentration of hypochlorous acid in the tank and consequently, a higher concentration released into the air. Excessively high concentrations of hypochlorous acid can corrode not only the components of the disinfection machine but also other substances in the external environment. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the first objective of this invention is to provide a control method for a disinfection device, which, by pumping waste liquid from a storage tank to a waste liquid container, ensures that the concentration of hypochlorous acid in the storage tank is low during the next disinfection cycle, preventing corrosion of the components of the disinfection device and other substances in the external environment.

[0004] A second objective of this invention is to provide a computer-readable storage medium.

[0005] The third objective of this invention is to provide a disinfection device.

[0006] The fourth objective of this invention is to provide another disinfection device.

[0007] To achieve the above objectives, a control method for a disinfection device is proposed according to a first aspect embodiment of the present invention. The disinfection device includes a storage tank, a waste liquid tank, and a pumping device. The pumping device is adapted to pump liquid from the storage tank into the waste liquid tank. The control method includes: detecting a first liquid level height information in the storage tank and a second liquid level height information in the waste liquid tank; after the disinfection device completes the disinfection function, if the liquid level in the storage tank is determined to be greater than or equal to a first preset liquid level based on the first liquid level height information, and the liquid level in the waste liquid tank is determined to be less than a second preset liquid level based on the second liquid level height information, then controlling the pumping device to pump liquid from the storage tank to the waste liquid tank.

[0008] According to the control method of the disinfection equipment of the present invention, firstly, the first liquid level height information in the storage tank and the second liquid level height information in the waste liquid tank are detected. Then, after the disinfection equipment completes the disinfection function, if the liquid level in the storage tank is determined to be greater than or equal to a first preset liquid level based on the first liquid level height information, and the liquid level in the waste liquid tank is determined to be less than a second preset liquid level based on the second liquid level height information, the pumping device is controlled to pump the liquid in the storage tank to the waste liquid tank. Thus, after the disinfection equipment completes the disinfection function, the waste liquid in the storage tank is pumped to the waste liquid tank. Because there is no waste liquid in the storage tank, the concentration of hypochlorous acid in the storage tank is low during the next disinfection, which will not corrode the components of the disinfection equipment or other substances in the external environment.

[0009] According to one embodiment of the present invention, the disinfection device further includes a liquid storage tank, which is adapted to add liquid to a liquid storage tank. The control method further includes, before controlling the pumping device to pump the liquid in the liquid storage tank to the waste liquid tank, if it is determined that the liquid level in the liquid storage tank is less than a first preset liquid level based on the first liquid level height information, controlling the disinfection device to issue a liquid shortage warning message so that after adding liquid to the liquid storage tank, it is determined that the liquid level in the liquid storage tank is greater than or equal to the first preset liquid level.

[0010] According to an embodiment of the present invention, after the disinfection equipment completes the disinfection function, the control method further includes: if the liquid level in the storage tank is determined to be greater than or equal to the first preset liquid level based on the first liquid level height information, and the liquid level in the waste liquid tank is determined to be greater than or equal to the second preset liquid level based on the second liquid level height information, then the disinfection preparation device of the disinfection equipment is controlled to prepare the disinfection medium.

[0011] To achieve the above objectives, a computer-readable storage medium is provided according to a second aspect of the present invention, on which a computer program is stored, which, when processed by a processor, executes the above-described control method for the disinfection device.

[0012] According to the computer-readable storage medium of the present invention, by executing the computer program of the control method of the above-described disinfection equipment, the waste liquid in the storage tank is pumped to the waste liquid tank, so that the concentration of hypochlorous acid in the storage tank is low during the next disinfection, so as not to corrode the components of the disinfection equipment, nor to corrode other substances in the external environment.

[0013] To achieve the above objectives, a disinfection device is provided according to a third aspect of the present invention, including a memory, a processor, and an electrolytic water control program for the disinfection device stored in the memory and executable on the processor. When the processor executes the control program for the disinfection device, the above-described control method for the disinfection device is implemented.

[0014] According to the disinfection equipment of the present invention, the processor executes the program of the control method of the above-mentioned disinfection equipment, and pumps the waste liquid in the storage tank to the waste liquid tank, so that the concentration of hypochlorous acid in the storage tank is low during the next disinfection, so as not to corrode the components of the disinfection equipment, nor to corrode other substances in the external environment.

[0015] To achieve the above objectives, according to a fourth aspect of the present invention, another disinfection device is provided, comprising: a storage tank, a waste liquid tank, and a pumping device, wherein the pumping device is disposed in the storage tank and is adapted to pump liquid from the storage tank into the waste liquid tank; a first liquid level detection element for detecting a first liquid level height information in the storage tank; a second liquid level detection element for detecting a second liquid level height information in the waste liquid tank; and a controller, wherein after the disinfection device completes the disinfection function, the controller is configured to determine, based on the first liquid level height information, that the liquid level in the storage tank is greater than or equal to a first preset liquid level, and based on the second liquid level height information, determine that the liquid level in the waste liquid tank is less than a second preset liquid level, and then control the pumping device to pump liquid from the storage tank into the waste liquid tank.

[0016] According to an embodiment of the disinfection equipment of the present invention, a first liquid level detection device detects the first liquid level height information in the storage tank, and a second liquid level detection device detects the second liquid level height information in the waste liquid tank. After the disinfection equipment completes the disinfection function, the controller determines, based on the first liquid level height information, that the liquid level in the storage tank is greater than or equal to a first preset liquid level, and based on the second liquid level height information, determines that the liquid level in the waste liquid tank is less than a second preset liquid level. Then, the controller controls the pumping device to pump the liquid from the storage tank to the waste liquid tank. Thus, after the disinfection equipment completes the disinfection function, the waste liquid in the storage tank is pumped to the waste liquid tank. Because there is no waste liquid in the storage tank, the concentration of hypochlorous acid in the storage tank is low during the next disinfection, preventing corrosion of the components of the disinfection equipment and other substances in the external environment.

[0017] According to one embodiment of the present invention, the disinfection device further includes: a liquid storage tank, which is adapted to add liquid to a liquid storage tank, wherein, before the control pumping device pumps the liquid in the liquid storage tank to the waste liquid tank, if the controller determines that the liquid level in the liquid storage tank is less than a first preset liquid level based on the first liquid level height information, the controller controls the disinfection device to issue a liquid shortage warning message so that after adding liquid to the liquid storage tank, it is determined that the liquid level in the liquid storage tank is greater than or equal to the first preset liquid level.

[0018] According to one embodiment of the present invention, after the disinfection equipment completes the disinfection function, if the controller determines that the liquid level in the storage tank is greater than or equal to the first preset liquid level based on the first liquid level height information, and determines that the liquid level in the waste liquid tank is greater than or equal to the second preset liquid level based on the second liquid level height information, then the controller controls the disinfection preparation device of the disinfection equipment to prepare the disinfection medium.

[0019] According to one embodiment of the present invention, the disinfection device further includes: a mounting frame, a liquid storage tank and a waste liquid tank are both installed in the mounting frame, and a first liquid level detection element includes: a first float and a first Hall sensor, the first Hall sensor is disposed in the mounting frame, the inner side wall of the liquid storage tank corresponding to the first Hall sensor is provided with a first float cover, the first float is disposed in the first float cover, and the first float cover corresponds to the first Hall sensor.

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] The following description, with reference to the accompanying drawings, describes the disinfection device, the control method for the disinfection device, and the storage medium according to embodiments of the present invention.

[0039] Figure 1 This is a schematic diagram of a disinfection device 100 according to an embodiment of the present invention. Figure 1 As shown, the disinfection equipment 100 includes a liquid storage tank 10, a waste liquid tank 20, a pumping device 30, a first liquid level detection element 40, a second liquid level detection element 50, and a controller 60.

[0040] The system includes a storage tank 10 for storing a disinfectant solution, a disinfection preparation device and a water transfer tray 11. The disinfection preparation device electrolyzes the disinfectant solution to obtain a disinfectant medium (e.g., hypochlorous acid), and the water transfer tray 11 releases the electrolyzed disinfectant medium into the air. A waste liquid tank 20 stores the liquid in the storage tank 10. A pumping device 30 pumps the liquid in the storage tank 10 into the waste liquid tank 20. A first liquid level detector 40 and a second liquid level detector 50 detect the first liquid level in the storage tank 10 and the second liquid level in the waste liquid tank 20, respectively. A controller 60 generates a control signal based on the first and second liquid level information to control the pumping device 30 to pump the liquid in the storage tank 10 into the waste liquid tank 20.

[0041] In this embodiment, the control method of the disinfection device 100 can be applied to the controller 60. When the controller 60 receives a control command to activate the disinfection function, it outputs a control signal to the first liquid level detector 40 and the second liquid level detector 50. The first liquid level detector 40 and the second liquid level detector 50 detect the first liquid level height information in the storage tank 10 and the second liquid level height information in the waste liquid tank 20, and output a control signal to the disinfection preparation device to electrolyze the disinfection solution in the storage tank 10. At the same time, it can output a control signal to activate the pumping device 30 to discharge the disinfection solution in the storage tank 10 into the waste liquid tank 20.

[0042] Figure 2 This is a schematic flowchart of a control method for a disinfection device according to a first embodiment of the present invention. Figure 2 As shown, the control method includes the following steps:

[0043] S101, detect the first liquid level height information in the storage tank and the second liquid level height information in the waste liquid tank.

[0044] Specifically, the first liquid level detection device and the second liquid level detection device detect the first liquid level height information in the storage tank and the second liquid level height information in the waste liquid tank, respectively. The first liquid level detection device and the second liquid level detection device include, but are not limited to, hydrostatic level gauges, level transmitters and water level sensors, and no specific restrictions are imposed here.

[0045] S102, after the disinfection equipment completes the disinfection function, if the liquid level in the storage tank is determined to be greater than or equal to the first preset liquid level based on the first liquid level height information, and the liquid level in the waste liquid tank is determined to be less than the second preset liquid level based on the second liquid level height information, then the pumping device is controlled to pump the liquid in the storage tank to the waste liquid tank.

[0046] Specifically, after the disinfection equipment completes its disinfection function and before the next disinfection, if the liquid level in the storage tank is greater than or equal to the first preset level, it indicates that waste liquid has been stored in the storage tank after the disinfection equipment has completed disinfection. If the waste liquid is not drained, the concentration of hypochlorous acid in the storage tank will be too high during the next disinfection. If the liquid level in the waste liquid tank is less than the second preset level, it indicates that the waste liquid tank is not full, and the waste liquid in the storage tank can be drained into the waste liquid tank. At this time, the controller outputs a control signal to cause the pumping device to pump the waste liquid in the storage tank to the waste liquid tank. During the next disinfection, the disinfection preparation device electrolyzes the disinfection solution in the storage tank. Because there is no waste liquid containing hypochlorous acid generated during the previous disinfection, the concentration of hypochlorous acid in the storage tank is low and will not corrode the components of the disinfection equipment or other substances in the external environment.

[0047] In one alternative implementation, to further ensure that all waste liquid in the storage tank can be discharged into the waste liquid tank, the capacity of the waste liquid tank can be made larger than the capacity of the storage tank. For example, the capacity of the storage tank is 500 mL and the capacity of the waste liquid tank is 650 mL.

[0048] For example, when the disinfection function of the disinfection equipment is activated, the controller outputs a control signal to cause the first and second liquid level detectors to detect the first liquid level in the storage tank and the second liquid level in the waste liquid tank in real time. To complete one disinfection cycle, the disinfection preparation device needs to electrolyze the disinfectant solution in the storage tank five times. After the five electrolysis cycles are completed and before the next electrolysis begins, if the liquid level in the storage tank is greater than or equal to the first preset liquid level and the liquid level in the waste liquid tank is less than the second preset liquid level, the controller controls the pumping device to pump the waste liquid from the storage tank to the waste liquid tank until the waste liquid tank is full, at which point the controller stops the pumping device.

[0049] In the above embodiments, after the disinfection equipment completes the disinfection function, the waste liquid in the storage tank is pumped to the waste liquid tank. Because there is no waste liquid in the storage tank, the concentration of hypochlorous acid in the storage tank is low during the next disinfection, which will not corrode the components of the disinfection equipment or other substances in the external environment.

[0050] In some embodiments, such as Figure 1 As shown, the disinfection device 100 also includes a liquid storage tank 70, which is adapted to add liquid to the liquid storage tank 10. Before the control pumping device pumps the liquid in the liquid storage tank to the waste liquid tank, the control method further includes: if it is determined from the first liquid level height information that the liquid level in the liquid storage tank is less than the first preset liquid level, then the disinfection device is controlled to issue a liquid shortage warning message so that after adding liquid to the liquid storage tank, it is determined that the liquid level in the liquid storage tank is greater than or equal to the first preset liquid level.

[0051] Specifically, the storage tank contains disinfectant solution. When the amount of disinfectant solution in the storage tank decreases, the storage tank automatically adds more. The disinfectant solution stored in the storage tank can be used to complete one disinfection cycle of the disinfection equipment. When the disinfection equipment completes one disinfection cycle, there is no remaining disinfectant solution in the storage tank, and no more disinfectant solution is added. The liquid level in the storage tank will be lower than a first preset level. Therefore, before the pumping device pumps the liquid from the storage tank to the waste tank, if the liquid level in the storage tank is lower than the first preset level, it indicates that there is a lack of disinfectant solution in the storage tank, and disinfectant solution needs to be added until the liquid level in the storage tank is greater than or equal to the first preset level before the disinfection equipment can perform the next disinfection cycle. In addition, while adding disinfectant solution to the storage tank, the liquid in the waste tank can also be emptied, ensuring that all the liquid in the storage tank can be pumped to the waste tank later. The disinfection equipment can only perform the next disinfection cycle after adding disinfectant solution to the storage tank and emptying the liquid in the waste tank.

[0052] In this embodiment, after the disinfection equipment completes its disinfection function, the user can be promptly reminded to add disinfectant solution to the storage tank to avoid the disinfection equipment operating in a low-liquid state for an extended period, which could lead to a dangerous situation.

[0053] In some embodiments, after the disinfection equipment completes the disinfection function, the control method further includes: if the liquid level in the storage tank is determined to be greater than or equal to the first preset liquid level based on the first liquid level height information, and the liquid level in the waste liquid tank is determined to be greater than or equal to the second preset liquid level based on the second liquid level height information, then the disinfection preparation device of the disinfection equipment is controlled to prepare the disinfection medium.

[0054] Specifically, to conserve disinfectant solution and avoid frequent additions and emptying of the waste tank, thus improving user experience, the liquid in the storage tank is not pumped to the waste tank during a single disinfection cycle. Instead, the liquid is pumped to the waste tank only after one disinfection cycle is completed and before the start of the next. Therefore, when the liquid level in the storage tank is greater than or equal to the first preset level and the liquid level in the waste tank is greater than or equal to the second preset level, it indicates that the liquid in the storage tank has been pumped to the waste tank, and the disinfection equipment is operating within a disinfection cycle. The controller directly controls the disinfection preparation device to prepare the disinfection medium.

[0055] For example, to complete one disinfection cycle, the disinfection equipment requires the disinfection preparation device to electrolyze the disinfectant solution in the storage tank five times. Only before the first electrolysis does the liquid in the storage tank need to be pumped to the waste tank to ensure the liquid level in the waste tank is greater than or equal to a second preset level. After the first five electrolysis cycles, it is not necessary to pump the liquid in the storage tank to the waste tank. Therefore, during the first five electrolysis cycles (i.e., one disinfection cycle), the liquid level in the storage tank is always greater than or equal to the first preset level, and the liquid level in the waste tank is always equal to the second preset level. When it is detected that the liquid level in the storage tank is greater than or equal to the first preset level and the liquid level in the waste tank is greater than or equal to the second preset level, the disinfection equipment does not need to pump the liquid in the storage tank to the waste tank during the disinfection cycle. The controller directly controls the disinfection preparation device to electrolyze the disinfectant solution in the storage tank to generate hypochlorous acid.

[0056] In this embodiment, the liquid levels in the storage tank and waste tank can also be used to determine whether the disinfection equipment is in a disinfection cycle. When the disinfection equipment is in a disinfection cycle, it is not necessary to extract the liquid from the storage tank, which saves the use of disinfection solution and improves the user experience.

[0057] The technical solution of this application will be further described in detail below with reference to specific implementation methods:

[0058] Figure 7 This is a schematic flowchart of a control method for a disinfection device according to a second embodiment of the present invention. In this embodiment, the first liquid level detection element is a first Hall sensor and a first float, and the second liquid level detection element is a second Hall sensor and a second float. Figure 7 As shown, the control method includes the following steps:

[0059] S201, the controller is in working condition and receives the control command to activate the disinfection function.

[0060] S202, the first Hall sensor and the second Hall sensor respectively detect the first float and the second float in the liquid storage tank and the waste liquid tank.

[0061] S203, whether the first Hall sensor detects the first float. If the first Hall sensor detects the first float, proceed to step S204. If the first Hall sensor does not detect the first float, proceed to step S211.

[0062] S204, the first float is at a high water level.

[0063] S205, there is liquid in the storage tank.

[0064] S206, whether the second Hall sensor detects the second float. If the second Hall sensor detects the second float, proceed to step S214. If the second Hall sensor does not detect the second float, proceed to step S207.

[0065] S207, the second float is at a high water level.

[0066] S208, Waste liquid tank is full.

[0067] S209, when the disinfection equipment is in a disinfection cycle, it is not necessary to pump the liquid in the storage tank into the waste liquid tank.

[0068] S210, the controller sends a control command to start the disinfection preparation device to prepare hypochlorous acid.

[0069] S211, the first float is at a low water level.

[0070] S212, the liquid storage tank is low on water.

[0071] S213, the controller controls the disinfection equipment to issue a water shortage alarm to remind the user to add water.

[0072] S214, the second float is at a low water level.

[0073] S215, Waste liquid tank is not full.

[0074] S216, the controller sends a control command to start the pumping device to pump the liquid in the storage tank to the waste liquid tank.

[0075] In this embodiment, the disinfection equipment detects the first and second floats using a first Hall sensor and a second Hall sensor to obtain liquid level information in the storage tank and waste tank. Based on this information, it determines whether the disinfection equipment is in a disinfection cycle. If it is, there is no need to pump the liquid from the storage tank into the waste tank, saving disinfectant solution and avoiding frequent refilling and emptying of the waste tank, thus improving the user experience. When the disinfection equipment completes a disinfection cycle, it reminds the user to add water to the storage tank to prevent the equipment from operating in a water-deficient state for an extended period, which could lead to a dangerous situation. Before the next disinfection cycle begins, the waste liquid in the storage tank is pumped into the waste tank. Because there is no waste liquid in the storage tank, the hypochlorous acid concentration in the storage tank will be low during the next disinfection, preventing corrosion of the components of the disinfection equipment or other substances in the external environment.

[0076] In summary, according to the control method of the disinfection equipment according to the embodiments of the present invention, after the disinfection equipment completes the disinfection function, the waste liquid in the storage tank is pumped to the waste liquid tank. Because there is no waste liquid in the storage tank, the concentration of hypochlorous acid in the storage tank is low during the next disinfection, which will not cause corrosion to the components of the disinfection equipment, nor will it cause corrosion to other substances in the external environment.

[0077] Corresponding to the above embodiments, the present invention also proposes a computer-readable storage medium storing a computer program thereon, which, when processed by a processor, executes the control method of the disinfection device described in the above embodiments.

[0078] According to the computer-readable storage medium of the present invention, by executing the computer program of the control method of the above-described disinfection equipment, the waste liquid in the storage tank is pumped to the waste liquid tank, so that the concentration of hypochlorous acid in the storage tank is low during the next disinfection, so as not to corrode the components of the disinfection equipment, nor to corrode other substances in the external environment.

[0079] Corresponding to the above embodiments, such as Figure 3 As shown, an embodiment of the present invention also proposes a disinfection device 100, including a memory 110, a processor 120, and an electrolyzed water control program for the disinfection device stored in the memory 110 and executable on the processor 120. When the processor 120 executes the control program for the disinfection device, it implements the control method for the disinfection device described in the above embodiment.

[0080] According to the disinfection equipment of the present invention, the processor executes the program of the control method of the above-mentioned disinfection equipment, and pumps the waste liquid in the storage tank to the waste liquid tank, so that the concentration of hypochlorous acid in the storage tank is low during the next disinfection, so as not to corrode the components of the disinfection equipment, nor to corrode other substances in the external environment.

[0081] Corresponding to the above embodiments, the present invention also proposes another disinfection device.

[0082] like Figure 1 As shown, the disinfection equipment 100 includes: a liquid storage tank 10, a waste liquid tank 20, a pumping device 30, a first liquid level detection element 40, a second liquid level detection element 50, and a controller 60.

[0083] The pumping device 30 is located inside the storage tank 10 and is adapted to pump the liquid in the storage tank 10 into the waste liquid tank 20. The first liquid level detection element 40 is used to detect the first liquid level height information in the storage tank 10. The second liquid level detection element 50 is used to detect the second liquid level height information in the waste liquid tank 20. After the disinfection equipment 100 completes the disinfection function, the controller 60 is used to determine, based on the first liquid level height information, that the liquid level in the storage tank 10 is greater than or equal to the first preset liquid level, and based on the second liquid level height information, that the liquid level in the waste liquid tank 20 is less than the second preset liquid level, and then controls the pumping device 30 to pump the liquid in the storage tank 10 into the waste liquid tank 20.

[0084] Specifically, the first liquid level detection element 40 and the second liquid level detection element 50 respectively detect the first liquid level height information in the storage tank 10 and the second liquid level height information in the waste liquid tank 20. After the disinfection equipment 100 completes the disinfection function and before the next disinfection, if the liquid level in the storage tank 10 is greater than or equal to the first preset liquid level, it indicates that the storage tank 10 has stored waste liquid after the disinfection equipment 100 has completed disinfection. If the waste liquid is not drained, the hypochlorous acid concentration in the storage tank 10 will be too high during the next disinfection. If the liquid level in the waste liquid tank 20 is less than the second preset liquid level, it indicates that the waste liquid tank 20 is not full, and the waste liquid in the storage tank 10 can be drained into the waste liquid tank 20. At this time, the controller 60 outputs a control signal to make the pumping device 30 pump the waste liquid in the storage tank 10 to the waste liquid tank 20. During the next disinfection, the disinfection preparation device electrolyzes the disinfection solution in the storage tank 10. Because there is no waste liquid containing hypochlorous acid generated during the previous disinfection, the concentration of hypochlorous acid in the storage tank 10 is low and will not corrode the components of the disinfection equipment 100, nor will it corrode other substances in the external environment.

[0085] In an optional embodiment, in order to further ensure that all the waste liquid in the storage tank 10 can be discharged into the waste liquid tank 20, the capacity of the waste liquid tank 20 can be made greater than the capacity of the storage tank 10. For example, the capacity of the storage tank 10 is 500mL and the capacity of the waste liquid tank 20 is 650mL.

[0086] For example, when the disinfection function of the disinfection equipment 100 is activated, the controller 60 outputs a control signal to cause the first liquid level detector 40 and the second liquid level detector 50 to detect the first liquid level height information in the storage tank 10 and the second liquid level height information in the waste liquid tank 20 in real time. For the disinfection equipment 100 to complete one disinfection function, the disinfection preparation device needs to electrolyze the disinfection solution in the storage tank 10 five times. After the five electrolysis cycles are completed, before the next electrolysis begins, if the liquid level in the storage tank 10 is greater than or equal to the first preset liquid level and the liquid level in the waste liquid tank 20 is less than the second preset liquid level, the controller 60 controls the pumping device 30 to pump the waste liquid from the storage tank 10 to the waste liquid tank 20 until the waste liquid tank 20 is full, at which point the controller 60 controls the pumping device 30 to stop operating.

[0087] In one optional embodiment, the pumping device 30 includes a water pump 31 and a delivery pipe 32. The outlet of the water pump 31 is connected to the delivery pipe 32, which is located inside the storage tank 10. The flow rate of the water pump 31 can be controlled at 1L / min, further ensuring that the liquid in the storage tank 10 can be pumped into the waste liquid tank 20 in a short time, thereby saving the working time of the disinfection equipment.

[0088] In the above embodiment, after the disinfection equipment 100 completes the disinfection function, the waste liquid in the storage tank 10 is pumped to the waste liquid tank 20. Since there is no waste liquid in the storage tank 10, the concentration of hypochlorous acid in the storage tank 10 is low during the next disinfection, which will not corrode the components of the disinfection equipment 100, nor will it corrode other substances in the external environment.

[0089] In some embodiments, such as Figure 1 As shown, the disinfection device 100 also includes a liquid storage tank 70, which is adapted to add liquid to the liquid storage tank 10. Before the control pumping device 30 pumps the liquid in the liquid storage tank 10 to the waste liquid tank 20, if the controller 60 determines that the liquid level in the liquid storage tank 10 is less than the first preset liquid level based on the first liquid level height information, the control disinfection device 100 issues a liquid shortage warning message to the liquid storage tank 70 so that after adding liquid to the liquid storage tank 70, the liquid level in the liquid storage tank 10 is determined to be greater than or equal to the first preset liquid level.

[0090] Specifically, the storage tank 70 contains disinfectant solution. When the amount of disinfectant solution in the storage tank 10 decreases, the storage tank 70 automatically adds more disinfectant solution. The disinfectant solution stored in the storage tank 70 can be used by the disinfection equipment 100 to complete one disinfection cycle. When the disinfection equipment 100 completes one disinfection cycle, there is no remaining disinfectant solution in the storage tank 70, and no more disinfectant solution is added to the storage tank 10. The liquid level in the storage tank 10 will be lower than the first preset liquid level. Therefore, before the pumping device 30 pumps the liquid in the storage tank 10 to the waste liquid tank 20, if the liquid level in the storage tank 10 is lower than the first preset liquid level, it indicates that the storage tank 70 is short of disinfectant solution and needs to be added until the liquid level in the storage tank 10 is greater than or equal to the first preset liquid level before the disinfection equipment 100 can perform the next disinfection cycle. In addition, while adding disinfectant solution to the storage tank 70, the liquid in the waste liquid tank 20 can also be emptied. This ensures that all the liquid in the storage tank 10 can be pumped into the waste liquid tank 20 subsequently. The disinfection equipment 100 can only be used for the next disinfection cycle after adding disinfectant solution to the storage tank 70 and emptying the waste liquid tank 20.

[0091] In this embodiment, after the disinfection device 100 completes the disinfection function, the user can be promptly reminded to add disinfectant solution to the storage tank 70 to avoid the disinfection device 100 operating in a state of insufficient liquid for a long time, which could lead to a dangerous situation.

[0092] In some embodiments, after the disinfection device 100 completes the disinfection function, if the controller 60 determines that the liquid level in the storage tank 10 is greater than or equal to the first preset liquid level based on the first liquid level height information, and determines that the liquid level in the waste liquid tank 20 is greater than or equal to the second preset liquid level based on the second liquid level height information, then the controller controls the disinfection preparation device of the disinfection device 100 to prepare the disinfection medium.

[0093] Specifically, to conserve disinfectant solution and avoid frequent additions and emptying of the waste liquid tank 20, thereby improving user experience, the liquid in the storage tank 10 is not pumped to the waste liquid tank 20 during one disinfection cycle of the disinfection device 100. The liquid is only pumped to the waste liquid tank 20 after one disinfection cycle is completed and before the start of the next. Therefore, when the liquid level in the storage tank 10 is greater than or equal to the first preset level and the liquid level in the waste liquid tank 20 is greater than or equal to the second preset level, it indicates that the liquid in the storage tank 10 has been pumped to the waste liquid tank 20, and the disinfection device 100 is operating within a disinfection cycle. The controller 60 directly controls the disinfection preparation device to prepare the disinfection medium.

[0094] For example, for the disinfection equipment 100 to complete one disinfection cycle, the disinfection preparation device needs to electrolyze the disinfectant solution in the storage tank 10 five times. Only before the first electrolysis does the liquid in the storage tank 10 need to be pumped to the waste tank 20 to ensure that the liquid level in the waste tank 20 is greater than or equal to the second preset liquid level. After the first to fifth electrolysis cycles, it is not necessary to pump the liquid in the storage tank 10 to the waste tank 20. Therefore, during the first to fifth electrolysis cycles (i.e., one disinfection cycle), the liquid level in the storage tank 10 is always greater than or equal to the first preset liquid level, and the liquid level in the waste tank 20 is always equal to the second preset liquid level. When it is detected that the liquid level in the storage tank 10 is greater than or equal to the first preset liquid level and the liquid level in the waste tank 20 is greater than or equal to the second preset liquid level, the disinfection equipment 100 does not need to pump the liquid in the storage tank 10 to the waste tank 20 during the disinfection cycle. The controller 60 directly controls the disinfection preparation device to electrolyze the disinfectant solution in the storage tank 10 to generate hypochlorous acid.

[0095] In this embodiment, the liquid levels in the storage tank 10 and the waste liquid tank 20 can also be used to determine whether the disinfection equipment 100 is in a disinfection cycle. When the disinfection equipment 100 is in a disinfection cycle, it is not necessary to extract the liquid from the storage tank 10, which saves the use of disinfection solution and improves the user experience.

[0096] In some embodiments, such as Figure 1 and Figure 4 As shown, the disinfection equipment 100 also includes: a mounting frame 80, a liquid storage tank 10 and a waste liquid tank 20, all of which are installed in the mounting frame 80. The first liquid level detection element 40 includes: a first float 41 and a first Hall sensor 42. The first Hall sensor 42 is disposed in the mounting frame 80. The inner sidewall of the liquid storage tank 10 corresponding to the first Hall sensor 42 is provided with a first float cover 12. The first float 41 is disposed in the first float cover 12. The first float cover 12 corresponds to the first Hall sensor 42.

[0097] Specifically, the surface magnetic field strength of the first float 41 is in the range of 3500±200 Gauss, the release magnetic field strength of the first Hall sensor 42 is 45 Gauss, the action magnetic field strength is 60 Gauss, the input voltage of the first Hall sensor 42 is 5V, and it outputs a low level of 0-0.8V when it senses the float and a high level of 4.5-5V when it does not sense the float.

[0098] In this embodiment, the first liquid level height information of the storage tank 10 is detected by the first Hall sensor 42. Since the Hall sensor has high accuracy, relatively accurate first liquid level height information can be obtained.

[0099] In some embodiments, such as Figure 1 and Figure 4As shown, the disinfection equipment 100 also includes: a mounting frame 80, a liquid storage tank 10 and a waste liquid tank 20, all of which are installed in the mounting frame 80. The second liquid level detection element 50 includes: a second float 51 and a second Hall sensor 52. The second Hall sensor 52 is disposed in the mounting frame 80. The inner side wall of the waste liquid tank 20 corresponding to the second Hall sensor 52 is provided with a second float cover 21. The second float 51 is disposed in the second float cover 21, and the second float cover 21 corresponds to the second Hall sensor 52.

[0100] Specifically, the surface magnetic field strength of the second float 51 is in the range of 3500±200 Gauss, the release magnetic field strength of the second Hall sensor 52 is 45 Gauss, the action magnetic field strength is 60 Gauss, the input voltage of the second Hall sensor 52 is 5V, and it outputs a low level of 0-0.8V when the float is sensed and a high level of 4.5-5V when the float is not sensed.

[0101] In this embodiment, the second liquid level height information of the waste liquid tank 20 is detected by the second Hall sensor 52. Since the Hall sensor has high accuracy, relatively accurate second liquid level height information can be obtained.

[0102] In one optional embodiment, the first liquid level detection element 40 and the second liquid level detection element 50 adopt the following... Figure 5 The installation method is shown. (As shown in the image.) Figure 6 As shown, when the storage tank 10 is low in liquid, the first float 41 is at a low water level and aligned with the first Hall sensor 42. At this time, the first Hall sensor 42 can detect the magnetic field of the first float 41, so the first Hall sensor 42 outputs a low level. Figure 5 As shown, when the storage tank 10 is not short of liquid, the first float 41 is at a high water level, far away from the first Hall sensor 42. At this time, the first Hall sensor 42 cannot detect the magnetic field of the first float 41, so the first Hall sensor 42 outputs a high level. Figure 6 As shown, when the waste liquid tank 20 is not full, the second float 51 is at a low water level and aligned with the second Hall sensor 52. At this time, the second Hall sensor 52 can detect the magnetic field of the second float 51, so the second Hall sensor 52 outputs a low level. Figure 5 As shown, when the waste liquid tank 20 is full, the second float 51 is at a high water level and is far away from the second Hall sensor 52. At this time, the second Hall sensor 52 cannot detect the magnetic field of the second float 51, so the second Hall sensor 52 outputs a high level.

[0103] It should be noted that the installation method of the first liquid level detection element 40 and the second liquid level detection element 50 is not limited to the following. Figure 5 The installation method shown can also be used, and there are no specific restrictions here.

[0104] The technical solution of this application will be further described in detail below with reference to specific implementation methods:

[0105] Figure 7 This is a schematic flowchart of a control method for a disinfection device according to a second embodiment of the present invention. The disinfection device 100 in this embodiment employs... Figure 5 The installation method is shown. (As shown in the image.) Figure 7 As shown, the control method includes the following steps:

[0106] S201, the controller is in working condition and receives the control command to activate the disinfection function.

[0107] S202, the first Hall sensor and the second Hall sensor respectively detect the first float and the second float in the liquid storage tank and the waste liquid tank.

[0108] S203, whether the first Hall sensor detects the first float. If the first Hall sensor detects the first float, proceed to step S204. If the first Hall sensor does not detect the first float, proceed to step S211.

[0109] S204, the first float is at a high water level.

[0110] S205, there is liquid in the storage tank.

[0111] S206, whether the second Hall sensor detects the second float. If the second Hall sensor detects the second float, proceed to step S214. If the second Hall sensor does not detect the second float, proceed to step S207.

[0112] S207, the second float is at a high water level.

[0113] S208, Waste liquid tank is full.

[0114] S209, when the disinfection equipment is in a disinfection cycle, it is not necessary to pump the liquid in the storage tank into the waste liquid tank.

[0115] S210, the controller sends a control command to start the disinfection preparation device to prepare hypochlorous acid.

[0116] S211, the first float is at a low water level.

[0117] S212, the liquid storage tank is low on water.

[0118] S213, the controller controls the disinfection equipment to issue a water shortage alarm to remind the user to add water.

[0119] S214, the second float is at a low water level.

[0120] S215, Waste liquid tank is not full.

[0121] S216, the controller sends a control command to start the pumping device to pump the liquid in the storage tank to the waste liquid tank.

[0122] In this embodiment, the disinfection equipment detects the first and second floats using a first Hall sensor and a second Hall sensor to obtain liquid level information in the storage tank and waste tank. Based on this information, it determines whether the disinfection equipment is in a disinfection cycle. If it is, there is no need to pump the liquid from the storage tank into the waste tank, saving disinfectant solution and avoiding frequent refilling and emptying of the waste tank, thus improving the user experience. When the disinfection equipment completes a disinfection cycle, it reminds the user to add water to the storage tank to prevent the equipment from operating in a water-deficient state for an extended period, which could lead to a dangerous situation. Before the next disinfection cycle begins, the waste liquid in the storage tank is pumped into the waste tank. Because there is no waste liquid in the storage tank, the hypochlorous acid concentration in the storage tank will be low during the next disinfection, preventing corrosion of the components of the disinfection equipment or other substances in the external environment.

[0123] In summary, according to the disinfection equipment of the present invention, after the disinfection equipment completes the disinfection function, the waste liquid in the storage tank is pumped to the waste liquid tank. Because there is no waste liquid in the storage tank, the concentration of hypochlorous acid in the storage tank is low during the next disinfection, which will not cause corrosion to the components of the disinfection equipment, nor will it cause corrosion to other substances in the external environment.
