[0049] Existing disinfection machines require sensors to detect indoor air quality. However, these sensors are constantly in contact with the outside environment because they need to monitor indoor air quality. Furthermore, current disinfection machines release hypochlorous acid when operating in electrolyzed water sterilization mode, and hypochlorous acid easily corrodes the sensors, shortening their lifespan. Therefore, existing disinfection machines suffer from a short sensor lifespan.

[0050] Please see Figure 1 , Figure 2 This invention proposes a disinfection machine 100, which includes a housing 10, a sensor 20, a first fan, and a switching valve 30. The housing 10 has a receiving cavity and a communicating hole for connecting the receiving cavity and indoor air. The sensor 20 is disposed in the receiving cavity for detecting the quality of indoor air. The first fan is disposed in the receiving cavity. The switching valve 30 is installed in the housing 10 for opening and closing the communicating hole.

[0051] Based on the previous embodiment, the sensor 20 is an aerosol sensor 20, which detects air quality by detecting the indoor aerosol concentration. Optionally, since PM2.5 is an important criterion for judging air quality, the sensor 20 is used to detect the concentration of PM2.5. Specifically, indoor air enters the accommodating cavity through the connecting hole, and when the sensor 20 is turned on, it detects the air flowing through it. To further introduce indoor air into the accommodating cavity, a first fan is also provided inside the accommodating cavity. The first fan operates to guide indoor air into the accommodating cavity through the connecting hole.

[0052] In existing disinfection machines 100, the connecting hole is always in contact with the outside environment. This means that the external airflow and sensor 20 are in constant contact. While the disinfection machine 100 has an electrolyzed water sterilization mode, in this mode, it releases chlorine-containing substances such as hypochlorous acid into the room to achieve sterilization. However, because chlorine-containing substances easily corrode sensor 20, prolonged exposure to this environment results in a shorter lifespan for sensor 20.

[0053] In an optional embodiment, the sterilizer 100 includes an ion sterilization module and an electrolyzed water sterilization module. When the ion sterilization module is running, the sterilizer 100 is in ion sterilization mode. In ion sterilization mode, the sterilizer 100 needs to detect indoor air quality via sensor 20. In electrolyzed water sterilization mode, the hypochlorous acid released into the room is corrosive to sensor 20. Therefore, the use of sensor 20 is stopped at this time. In ion sterilization mode, no substances harmful to sensor 20 are produced.

[0054] When the ion sterilization mode is activated

[0055] Therefore, the switching valve 30 is essential to improve the service life of the sensor 20. When the sterilizer 100 is in electrolyzed water sterilization mode, or when other substances in the air may contain corrosive materials to the sensor 20, the switching valve 30 can be controlled to close the connecting hole to isolate the accommodating cavity from the indoor air. However, when it is necessary to monitor indoor air quality and it is determined that substances in the indoor air will not damage the sensor 20, the switching valve 30 can be controlled to open the connecting hole, allowing indoor air to flow through the sensor 20.

[0056] Please see Figure 2 In one optional embodiment, the accommodating cavity is located at the top of the housing 10. In this embodiment, the sterilizer 100 includes a wet membrane and a second fan. The second fan draws in external airflow from the side of the sterilizer 100, which passes through the wet membrane and exits from the side, carrying the disinfectant. This purifies and sterilizes the indoor air. Therefore, the main air duct of the sterilizer 100 is typically located on its side. However, to avoid interference between the airflow path detected by the sensor 20 formed by the first fan within the accommodating cavity and the airflow path of the main air duct, the accommodating cavity is located at the top of the housing 10 of the sterilizer 100, thus avoiding obstruction of the main air duct of the sterilizer 100.

[0057] Please see Figure 3In an optional embodiment, a cover plate 11 is provided on the top of the housing 10, and an mounting plate 13 is provided inside the housing 10. The cover plate 11, the mounting plate 13, and the side plate 12 disposed between the cover plate 11 and the mounting plate 13 together form a mounting cavity. A sensor mounting box 21 is provided inside the mounting cavity. The sensor mounting box 21 and part of the side plate 12 together form the receiving cavity. The sensor mounting box 21 is used to isolate the mounting cavity and the receiving cavity. The communicating hole is provided on the side plate 12.

[0058] The cover plate 11, the mounting plate 13, and the side plate 12 disposed between the cover plate 11 and the mounting plate 13 together form a mounting cavity on the top of the sterilizer 100. The receiving cavity is disposed within the mounting cavity. Besides the receiving cavity, the mounting cavity can also accommodate other specific components. For ease of installation, the sensor 20 can be connected to the sensor mounting box 21. A communicating hole is provided on the side plate 12. During assembly, the sensor mounting box 21, the side plate 12 with the communicating hole, and the corresponding mounting plate 13 and cover plate 11 together enclose and form the receiving cavity, thus isolating the receiving cavity from the mounting cavity. Since the purpose of the sensor 20 is to detect indoor air quality, and the air quality inside the mounting cavity is obviously different from the indoor air quality, to ensure the accuracy of the sensor 20's detection, the remaining space inside the mounting cavity and the receiving cavity should be isolated. In one embodiment, the sensor mounting box 21 is used to isolate the receiving cavity from the remaining space of the mounting cavity.

[0059] Please see Figure 4 , Figure 5 In an optional embodiment, the housing 10 further includes a first grille plate 141, which is detachably mounted to the communicating hole. Specifically, the first grille plate 141 is in constant contact with the external environment, and over time, it tends to accumulate a significant amount of dust. The detachable connection of the first grille plate 141 to the housing 10 allows the user to easily remove it for cleaning or replacement.

[0060] Please see Figure 5 In one optional embodiment, a second grid plate 142 is further provided at the communicating hole, and the second grid plate 142 is disposed between the first grid plate 141 and the sensor 20. Furthermore, to prevent the user from directly contacting the sensor 20 when disassembling the first grid plate 141, thus avoiding damage to the sensor 20, a second grid plate 142 is also installed between the first grid plate 141 and the sensor 20. In one embodiment, to achieve multi-layered protection, a third grid plate 143 is further provided between the second grid plate 142 and the sensor 20.

[0061] Please see Figure 5 In one optional embodiment, the second grille plate 142 is arranged in a stepped shape. Optionally, multiple different types of sensors 20, such as humidity sensors 20 and temperature sensors 20, may also be disposed within the accommodating cavity. Since different types of sensors 20 have different installation positions, the stepped arrangement of the second grille plate 142 facilitates determining the installation position of each sensor 20. Based on the previous optional embodiment, the third grille plate 143 is also arranged in a stepped shape.

[0062] Please see Figure 6 , Figure 7 In an optional embodiment, the switching valve 30 is disposed within the accommodating cavity. The switching valve 30 includes a baffle 31 and a drive member 35. The drive member 35 is connected to the baffle 31 so that the baffle 31 has a first position that blocks the communication hole and the sensor 20, and a second position that opens the communication hole and the sensor 20.

[0063] The switching valve 30 can be located outside or inside the receiving cavity. For better sealing of the connecting hole, placing the switching valve 30 inside the receiving cavity provides a more effective barrier. Furthermore, when the baffle 31 blocks the connecting hole and the sensor 20, the baffle 31 is positioned between the third grid and the sensor 20. Further, the connecting hole refers to multiple grid holes on the third grid plate 143. The baffle 31 blocks the multiple connecting holes on the third grid plate 143, thereby blocking the sensor 20 from outdoor air.

[0064] Please see Figure 6 , Figure 7 In an optional embodiment, a guide rail 32 is provided within the accommodating cavity, and the driving member 35 is used to drive the baffle 31 to move along the guide rail 32. The provision of the guide rail 32 increases the stability of the baffle 31 during movement.

[0065] Please see Figure 7 In an optional embodiment, the switching valve 30 further includes a first gear 33 and a second gear 34 that mesh with each other. The driving member 35 is connected to the first gear 33, and the baffle 31 is connected to the second gear 34. Further, the first gear 33 is a driving gear, and the second gear 34 is a transmission gear. The meshing first gear 33 and second gear 34 are disposed between the driving member 35 and the baffle 31, further increasing the stability of the movement of the baffle 31.

[0066] Please see Figure 8The present invention also proposes a control method for a sterilizer 100, wherein the sterilizer 100 includes a housing 10, a receiving cavity is provided inside the housing 10, a sensor 20 is installed in the receiving cavity, a communicating hole is provided on the housing 10 to communicate with the receiving cavity, and a switching valve 30 for opening and closing the communicating hole is installed on the housing 10; the sterilizer 100 has an electrolyzed water sterilization module;

[0067] The steps of the control method for the sterilizer 100 include:

[0068] S1, Obtain the command to activate the electrolyzed water sterilization mode;

[0069] S2, after receiving the instruction to turn on the electrolyzed water sterilization mode, control the switching valve 30 to close the connecting hole;

[0070] S3, control the operation of the electrolyzed water sterilization module.

[0071] When step S1 is executed, the acquired command to activate the electrolyzed water sterilization mode can take various forms. In one embodiment, the command can be issued by the user. In another embodiment, the command can also be issued according to a preset program. When step S2 is executed, the switching valve 30 can be closed some time after the electrolyzed water sterilization mode activation command is acquired. Alternatively, the switching valve 30 can be closed immediately upon receiving the electrolyzed water sterilization mode activation command. After step S2 is completed, the switching valve 30 closes the connecting hole, isolating the indoor air from the containment cavity.

[0072] At this point, the electrolyzed water sterilization module begins operation. Specifically, the main principle of the electrolyzed water sterilization mode is the sodium salt-containing water in the water tank of the electrolyzed sterilizer 100. Taking NaCl as an example, after energizing, the sodium chloride (NaCl) in the saline solution ionizes with the water (H2O), generating hydrogen (H2) and chlorine (Cl2) at the cathode and anode, respectively. The chlorine or the hypochlorous acid droplets formed by the combination of chlorine and water have a disinfecting effect. However, the sensor 20 is exposed to highly corrosive environments such as chlorine or hypochlorous acid for a long time, and its service life is easily reduced due to corrosion. Moreover, the electrolyzed water sterilization mode mainly serves to sterilize and disinfect indoor air. The sensor 20 is used to detect the concentration of indoor air aerosols, such as PM2.5. When the electrolyzed water sterilization mode is running, this value fluctuates little, and the necessity of detection is low. Before executing step S3, the switching valve 30 is controlled to isolate the sensor 20 from the indoor air to prevent the sterilizing substances generated in step S3 from affecting the service life of the sensor 20.

[0073] Please see Figure 9 In an optional embodiment, the sterilizer 100 further includes a plasma sterilization module, and the control method of the sterilizer 100 further includes:

[0074] S4, Obtain the shutdown command for the electrolyzed water sterilization module;

[0075] S5, after the electrolyzed water sterilization module is turned off, obtain the start command of the ion sterilization module;

[0076] S6, obtain the time difference δT between the time point when the electrolyzed water sterilization module is turned off and the current time; when δT is greater than the preset value, control the switching valve 30 to open the connecting hole;

[0077] S7, after the switching valve 30 opens the connecting hole, the sensor 20 is controlled to operate.

[0078] Ion sterilization mode, also known as plasma disinfection, utilizes a bipolar plasma electrostatic field to decompose and break down negatively charged bacteria, polarizing and adsorbing dust. Optionally, it can be combined with components such as drug-impregnated activated carbon, electrostatic mesh, and photocatalytic devices for secondary sterilization and filtration. The treated clean air circulates rapidly in large quantities, maintaining the controlled environment at the "sterile and dust-free room" standard. Therefore, detecting indoor air quality, i.e., aerosol concentration, is particularly important for the dust removal function of the ion sterilization module. In one embodiment, sensor 20 is used to transmit indoor air quality values ​​to the controller, which adjusts various parameters of the disinfection machine 100 in ion sterilization mode based on the received indoor air quality values.

[0079] However, during the operation of the water electrolysis sterilization module and for a period of time after it is turned off, a certain amount of hypochlorous acid will still remain in the indoor air. If the switching valve 30 is opened immediately after the water electrolysis sterilization module is started, the residual hypochlorous acid may still corrode the sensor 20. Therefore, after the water electrolysis sterilization mode is activated, a detection step is added to reduce the possibility of corrosion of the sensor 20. Specifically, after the water electrolysis sterilization module is turned off, the concentration of hypochlorous acid in the room gradually decreases. That is, after a certain period of time, it can be determined that the hypochlorous acid present in the indoor air has little impact on the sensor 20. The switching valve 30 is opened to connect the orifice, and the indoor air quality is detected. In one embodiment, the time difference δT is not less than 2 minutes and not more than 5 minutes. In another embodiment, the time difference δT is 3 minutes.

[0080] Please see Figure 10 In an optional embodiment, after the switching valve 30 opens the communication port, the step of controlling the operation of the sensor 20 includes:

[0081] S71 controls the intermittent operation of the sensor 20.

[0082] Specifically, the sensor 20 can operate continuously or intermittently to collect values. Since the aerosol concentration in indoor air does not change significantly within a short time interval, and the intermittently operating sensor 20 has a longer lifespan than the continuously operating sensor 20, intermittent operation of the sensor 20 is preferred when the detection results are not significantly different. In one embodiment, the sensor 20 is controlled to collect values ​​intermittently during a period of 3 to 30 minutes after the electrolyzed water sterilization mode is turned off. In another embodiment, data is collected every 10 minutes.

[0083] Please see Figure 11 In an optional embodiment, the step of controlling the intermittent operation of the sensor 20 includes,

[0084] S711, Intermittently acquire the detection values ​​of the sensor 20;

[0085] S712, if the current detection value is lower than the previously acquired detection value, reduce the detection frequency of the sensor 20.

[0086] Specifically, as the plasma sterilization module operates, air quality gradually improves. That is, the aerosol concentration detected by sensor 20 gradually decreases, and the rate of change in aerosol concentration also decreases accordingly with the operation of the sterilization module, resulting in a flatter curve. Therefore, if the original detection frequency is maintained, the change in detection values ​​between adjacent readings is minimal. Thus, to further improve the detection lifespan of sensor 20, the detection frequency of sensor 20 is correspondingly reduced as the aerosol concentration decreases.

[0087] In one embodiment, if the current detection value is higher than the previously acquired detection value, the detection frequency of the sensor 20 needs to be increased.

[0088] If the controller receives a high level of indoor PM2.5 concentration, it can increase the power of the sterilizer 100 and reduce the detection interval of the sensor 20, and adjust the power of the sterilizer 100 according to the value fed back by the sensor 20.

[0089] The present invention also proposes a computer-readable storage medium storing a control program for a sterilizer, wherein the control program for the sterilizer, when executed by a processor, implements the various steps of the sterilizer control method described above.
