Description

Technical Field

[0001] This application relates to the field of wearable air conditioning technology, and in particular to a wearable air conditioner and its control method and storage medium. Background Technology

[0002] The working principle of a thermoelectric cooler (TEC) is as follows: when a direct current passes through a circuit composed of two different semiconductor materials (P-type and N-type), heat is transferred from one end to the other, causing one end to cool down (called the cold end) and the other end to heat up (called the hot end). With the development of TEC technology, TECs have been applied as temperature controllers in wearable devices, leading to portable and wearable air conditioners such as neck air conditioners and neck fans. These devices are popular with users due to their portability and cooling capabilities.

[0003] When a wearable air conditioner is in use with its cooling function, the cold end of the semiconductor cooler will have a lot of water vapor due to the entry of air. The water vapor will condense on the surface of the cold end to form water droplets. As the usage time increases, the internal water accumulation will increase, which will lead to obstruction of the air duct and reduction of air volume, thus affecting the cooling effect. Summary of the Invention

[0004] To address the existing technical problems, this application provides a wearable air conditioner that actively removes condensation, its control method, and a storage medium.

[0005] In a first aspect, a control method for a wearable air conditioner is provided, applied to a wearable air conditioner, the wearable air conditioner including a microcontroller, and a temperature controller, a first humidity sensor, and a condensation sensor electrically connected to the microcontroller, wherein the first humidity sensor and the condensation sensor are disposed at a first end of the temperature controller, the first end being the cold end when the wearable air conditioner is in a cooling state; the method includes: Acquire at least one of the humidity detection value of the first humidity sensor and the detection signal of the condensation sensor; the detection signal includes a condensation alarm signal emitted by the condensation sensor when it detects condensation on the surface. When the humidity detection value is greater than the threshold and / or the condensation alarm signal is obtained, the wearable air conditioner is controlled to run the condensation removal mode to remove the condensation.

[0006] Secondly, a microcontroller is provided, as well as a temperature controller, a first humidity sensor and a condensation sensor electrically connected to the microcontroller, wherein the first humidity sensor and the condensation sensor are disposed at a first end of the temperature controller, and the first end is the cold end when the wearable air conditioner is in a cooling state. The microcontroller includes a processor and a memory connected to the processor. The memory stores a computer program that can be executed by the processor. When the computer program is executed by the processor, it implements the steps of the wearable air conditioner control method described in the above embodiments.

[0007] Thirdly, a computer-readable storage medium is provided, on which a computer program is stored, which, when executed by a processor, implements the steps of the wearable air conditioner control method of the above embodiments.

[0008] The wearable air conditioner control method provided in the above embodiments, by setting a first humidity sensor and a condensation sensor at the cold end of the temperature controller, determines that the condensation removal conditions are met based on at least one of the humidity detection value of the first humidity sensor and the condensation detection result of the condensation sensor, and then controls the wearable air conditioner to operate in condensation removal mode. In this way, the condensation situation at the cold end of the temperature controller of the wearable air conditioner can be actively monitored and actively removed, preventing condensation accumulation from causing blockage of the air duct of the wearable air conditioner, affecting the heat dissipation of the hot end of the temperature controller, thereby leading to decreased cooling efficiency, user discomfort, and potential safety risks, thus ensuring the normal operation of the wearable air conditioner and the user experience.

Detailed Implementation

[0018] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the following description, the phrase "some embodiments" refers to a subset of all possible embodiments. It should be noted that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0021] In the following description, the terms "first, second, and third" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first, second, and third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0022] The working principle of a thermoelectric cooler (TEC) is as follows: when a direct current passes through a circuit composed of two different semiconductor materials (P-type and N-type), heat is transferred from one end to the other, causing one end to cool down (called the cold end) and the other end to heat up (called the hot end). With the development of TEC technology, TECs have been applied as temperature controllers in wearable devices, leading to portable and wearable air conditioners such as neck air conditioners and neck fans. These devices are popular with users due to their portability and cooling capabilities.

[0023] When a wearable air conditioner is in cooling mode, water vapor brought in by the air will condense into water droplets on the cold end surface of the temperature controller. As usage time increases, more water accumulates inside, which will obstruct the airflow and reduce the air volume, thus affecting the cooling effect.

[0024] To address the above problems, this application provides a wearable air conditioner, such as... Figures 1 to 5 As shown, the system includes: a temperature controller 101, a microcontroller 102, a first humidity sensor 1031, a fan 106, and a condensation sensor 1032. The temperature controller 101, the first humidity sensor 1031, and the condensation sensor 1032 are all electrically connected to the microcontroller 102.

[0025] Specifically, the temperature controller 101 is a thermoelectric cooler (TEC). The working principle of a thermoelectric cooler (TEC) is as follows: when a direct current flows through a circuit composed of two different semiconductor materials (P-type and N-type), heat is transferred from one end to the other, causing one end to cool down (called the cold end) and the other end to heat up (called the hot end). When the direction of the applied direct current is reversed, the direction of heat transfer is also reversed, causing the original cold end to become the hot end, and the original hot end to become the cold end.

[0026] In one embodiment, a first humidity sensor 1031 may be provided at the first end of the temperature controller 101 to monitor the risk of condensation on the surface of the first end when the first end is used as the cold end. It is understood that the first end of the temperature controller 101 is the wearing surface of the wearable air conditioner that comes into contact with the user's skin. Thus, when the first end of the temperature controller 101 operates as the cold end, the low temperature it generates can be directly transferred to the user's skin through this wearing surface, allowing the user to experience a cooling effect while wearing it.

[0027] The first humidity sensor 1031 should be positioned as close as possible to the surface of the first end of the temperature controller 101. This is because, when the first end is the cold end, the closer it is to the surface of the first end of the temperature controller 101, the more condensation will form. Positioning the first humidity sensor 1031 on the surface of the first end of the temperature controller 101 allows it to detect condensation and also provides a more accurate representation of the actual humidity level. In one embodiment, if the humidity reading of the first humidity sensor 1031 exceeds a threshold, it can be determined that condensation exists at the first end.

[0028] In one embodiment, a condensation sensor 1032 may be provided at the first end of the temperature controller 101. The microcontroller 102 acquires the detection signal from the condensation sensor 1032. The detection signal from the condensation sensor 1032 may include a condensation alarm signal emitted when condensation is detected, and a normal status signal emitted when no condensation is detected.

[0029] In one embodiment, the probe of the condensation sensor 1032 is a pair of closely interlaced but non-contacting metal electrodes. Normally, the electrodes are insulated from the air, resulting in extremely high resistance. When condensation covers the electrode surfaces, water forms a conductive bridge between the electrodes. Because water also has some ionic conductivity, the resistance between the electrodes drops sharply to several thousand ohms or even lower, indicating that the circuit is conducting.

[0030] Correspondingly, it can be configured such that when the first end of the temperature controller 101 is dry, the condensation sensor 1032 outputs a low-level signal as a normal state signal, while when the temperature at the first end is too low, moisture in the air condenses into water droplets and covers the sensor electrodes, and then outputs a high-level signal as a condensation alarm signal.

[0031] As can be seen, since the condensation sensor 1032 directly detects the presence of condensation through physical contact, while the first humidity sensor 1031 infers the occurrence of condensation based on humidity detection values, the condensation sensor 1032 is more reliable. The condensation sensor 1032 is typically only reliably triggered when condensation accumulates to a certain amount, sufficient to form a continuous conductive path between the electrodes. Therefore, when the condensation sensor 1032 detects the presence of condensation, it indicates a larger amount of condensation, while when the presence of condensation is inferred solely from humidity, the amount of condensation is smaller.

[0032] In one embodiment, the first humidity sensor 1031 and the condensation sensor 1032 are both attached to the first end of the temperature controller 101, and the first humidity sensor 1031 and the condensation sensor 1032 are spaced apart.

[0033] The surface of the first end (cold end) of the temperature controller 101 is the physical source of water vapor in the air undergoing a phase change and condensing into liquid upon cooling. The closer the first humidity sensor 1031 and the condensation sensor 1032 are to the surface of the first end (cold end) of the temperature controller 101, the more accurately they can capture the local humidity and the first tiny water droplets to precipitate. The higher the air humidity at that location, the closer it is to the critical state for condensation. This close-fitting arrangement ensures that the monitoring signal originates from the core area where condensation occurs, thereby improving detection accuracy and rapid response capability.

[0034] By arranging the first humidity sensor 1031 and the condensation sensor 1032 alternately on the cold end surface, the effective monitoring coverage can be expanded on the limited cold end surface. The two monitoring points can reflect the humidity and condensation conditions in a larger area (e.g., along different airflow paths), avoiding potential local missed detections due to an overly singular monitoring point, and improving the ability to perceive uneven condensation distribution.

[0035] Both the first humidity sensor 1031 and the condensation sensor 1032 are electrically connected to the microcontroller 102. The microcontroller 102 uses the humidity detection value of the first humidity sensor 1031 and the detection signal of the condensation sensor 1032 to implement the wearable air conditioner control method of this application.

[0036] Specifically, at least one of the humidity detection value of the first humidity sensor 1031 and the detection signal of the condensation sensor 1032 is acquired; the detection signal includes a condensation alarm signal emitted by the condensation sensor 1032 when condensation is detected on the surface; when the humidity detection value is greater than the threshold and / or a condensation alarm signal is acquired, the wearable air conditioner is controlled to run a condensation removal mode to remove the condensation.

[0037] By setting a first humidity sensor 1031 and a condensation sensor 1032 at the first end of the temperature controller 101, when the humidity detection value of the first humidity sensor 1031 is greater than a threshold, and / or when the detection signal of the condensation sensor 1032 is a condensation alarm, the wearable air conditioner is controlled to operate a condensation removal mode to remove condensation. In this way, the condensation situation at the first end of the temperature controller 101 of the wearable air conditioner can be actively monitored and actively removed, preventing condensation accumulation from blocking the air duct of the wearable air conditioner, affecting the heat dissipation of the hot end of the temperature controller, thereby leading to decreased cooling efficiency, user discomfort, and potential safety risks, thus ensuring the normal operation of the wearable air conditioner and the user experience.

[0038] In one embodiment, the wearable air conditioner may include a condensation detection module 103. The temperature controller 101, microcontroller 102, and condensation detection module 103 are all located inside the housing of the wearable air conditioner. The temperature controller 101 and the condensation detection module 103 are both electrically connected to the microcontroller 102.

[0039] The microcontroller 102 can be mounted on the PCB board 107 inside the handle section of the housing, and the microcontroller 102 and the condensation detection module 103 can be mounted inside the neck section of the housing. Optionally, the microcontroller can be a chip of model STM32L051C8T6, STM32G030, STM32L431, CS32G020 or other models, which is not limited here.

[0040] like Figures 1 to 5As shown, in one embodiment, a condensation detection module 103 can be provided at the first end of the temperature controller 101 to monitor the risk of condensation on the surface of the first end when the first end is used as the cold end. It can be understood that the first end of the temperature controller 101 is the wearing surface of the wearable air conditioner that comes into contact with the user's skin. Thus, when the first end of the temperature controller 101 operates as the cold end, the low temperature it generates can be directly transferred to the user's skin through this wearing surface, allowing the user to experience a cooling effect while wearing it.

[0041] The condensation detection module 103 is electrically connected to the microcontroller 102. The microcontroller 102 generates a switching control signal for the temperature controller 101 based on the detection results from the condensation detection module 103. For example, when the condensation detection module 103 detects condensation, it generates a switching control signal to switch the temperature controller 101 to heating mode, such as applying a reverse current to the temperature controller 101 to drive it into heating mode. Specifically, the microcontroller 102 controls the current direction of the temperature controller 101 to reverse, switching it from cooling mode to heating mode, and it operates according to preset heating parameters (such as target temperature, heating power, duration, etc.). At this time, the first end changes from the original cold end to the hot end, heating the surface where condensation has formed, causing it to evaporate and be removed.

[0042] In this embodiment, a condensation detection module 103 is set at the first end (cold end) of the temperature controller 101 used for cooling, that is, a condensation detection module 103 is set at the source of condensation to monitor whether condensation is generated. This enables the wearable air conditioner to have the physical basis to monitor condensation phenomena during wearable operation, and provides a reliable hardware prerequisite for actively realizing condensation removal control.

[0043] In one embodiment, the condensation detection module 103 may include the first humidity sensor 1031 described above. The first humidity sensor 1031 is disposed at the first end of the temperature controller 101 and is used to monitor the risk of condensation on the surface of the first end when the first end is the cold end.

[0044] In one embodiment, the condensation detection module 103 may include the condensation sensor 1032 described above. The condensation sensor 1032 is disposed at the first terminal of the temperature controller 101. The microcontroller 102 acquires the detection signal from the condensation sensor 1032. The detection signal from the condensation sensor 1032 may include a condensation alarm signal emitted when condensation is detected, and a normal status signal emitted when no condensation is detected.

[0045] In one embodiment, the condensation detection module 103 includes a first humidity sensor 1031 and a condensation sensor 1032. The first humidity sensor 1031 and the condensation sensor 1032 are both attached to the first end of the temperature controller 101 and are spaced apart.

[0046] The surface of the first end (cold end) of the temperature controller 101 is the physical source of water vapor in the air undergoing a phase change and condensing into liquid upon cooling. The closer the first humidity sensor 1031 and the condensation sensor 1032 are to the surface of the first end (cold end) of the temperature controller 101, the more accurately they can capture the local humidity and the first tiny water droplets to precipitate. The higher the air humidity at that location, the closer it is to the critical state for condensation to occur. This close-fitting arrangement ensures that the monitoring signal originates from the core area where condensation occurs, thereby improving detection accuracy and rapid response capability.

[0047] By arranging the first humidity sensor 1031 and the condensation sensor 1032 alternately on the cold end surface, the effective monitoring coverage can be expanded on the limited cold end surface. The two monitoring points can reflect the humidity and condensation conditions in a larger area (e.g., along different airflow paths), avoiding potential local missed detections due to an overly singular monitoring point, and improving the ability to perceive uneven condensation distribution.

[0048] In one embodiment, a skin detection module 109 is provided on the skin contact surface of the wearable air conditioner. The skin detection module 109 includes an infrared sensor and / or a capacitive sensor for detecting the wearing status of the wearable air conditioner. The skin detection module 109 is electrically connected to a microcontroller 102.

[0049] In one embodiment, an infrared sensor and / or a capacitive sensor are disposed on the skin contact surface of the wearable air conditioner to detect the wearing status of the wearable air conditioner. The infrared sensor and the capacitive sensor are electrically connected to the microcontroller 102.

[0050] Specifically, infrared sensors can be used to detect infrared radiation of specific wavelengths. When the wearable air conditioner is worn close to the skin, the infrared sensor receives infrared radiation emitted from the skin surface (related to body temperature). When the device is removed from the skin (e.g., placed on a table), the infrared signal received by the sensor abruptly changes to the radiation from environmental objects, whose intensity and characteristics differ from those of human skin. The microcontroller 102 can distinguish whether the wearable air conditioner is in contact with the skin or detached by monitoring the intensity, stability, or specific waveform characteristics of the infrared sensor signal.

[0051] The capacitive sensor electrodes form a tiny capacitor with the skin. When the wearable air conditioner is in close contact with the skin, the human body alters the electric field distribution between the capacitive sensor electrodes, causing a specific change in its capacitance value. When the wearable air conditioner is removed from the skin, the capacitance value returns to its baseline state. The microcontroller 102 determines whether the wearable air conditioner has made effective contact with the human skin by detecting the change in capacitance value or a specific threshold.

[0052] Using infrared sensors and / or capacitive sensors, the wearable air conditioner can detect whether it is in a wearing state. The microcontroller 102 uses the humidity detection value of the first humidity sensor 1031 and / or the detection signal of the condensation sensor 1032, as well as the wearing state, to generate a switching control signal for the temperature controller 101. For example, when the humidity detection value of the first humidity sensor 1031 is greater than a threshold and / or a condensation alarm signal is obtained from the condensation sensor 1032, and the wearer is not in a wearing state, a switching control signal is generated to switch the temperature controller 101 to heating mode, such as applying a reverse current to the temperature controller 101 to drive it into the heating state.

[0053] In this embodiment, the placement of infrared and / or capacitive sensors on the skin contact surface provides the hardware foundation for detecting the wearable air conditioner's status and the signal input and basis for condensation removal control. For example, if the humidity detection value of the first humidity sensor 1031 is greater than the threshold and / or a condensation alarm signal is received from the condensation sensor 1032, the infrared and / or capacitive sensors detect whether the wearable air conditioner is in a wearable state. If the wearable air conditioner is not in a wearable state, condensation removal is controlled to remove the condensation. This effectively prevents uncomfortable hot air or abnormal operating noise caused by condensation removal control when the user is wearing the wearable air conditioner, thus improving the user experience.

[0054] If the humidity detection value of the first humidity sensor 1031 is greater than the threshold and / or a condensation alarm signal is obtained from the condensation sensor 1032, then the infrared sensor and / or capacitive sensor detect whether the wearable air conditioner is in wearable mode; if the wearable air conditioner is not in wearable mode, then the wearable air conditioner is controlled to run the condensation removal mode to remove condensation.

[0055] This effectively prevents uncomfortable hot air or abnormal operating noise caused by the wearable air conditioner running in condensation removal mode when the user is wearing it, thus improving the user experience.

[0056] In one embodiment, such as Figures 1 to 5As shown, the wearable air conditioner also includes a battery module 110 electrically connected to the microcontroller 102. When the condensation removal mode needs to be run, if the humidity detection value of the first humidity sensor 1031 is greater than the threshold and / or the condensation alarm signal of the condensation sensor 1032 is obtained, the battery status of the battery module 110 is obtained; when the battery module 110 is in the charging state, the wearable air conditioner is controlled to run the condensation removal mode to remove condensation.

[0057] Therefore, when a condensation risk or condensation alarm signal is detected, if the wearable air conditioner's battery module 110 is in a discharging state (i.e., not charging), the high-energy-consuming condensation removal mode (such as TEC reverse high-power heating) will be temporarily suspended. This prioritizes ensuring the battery power used for the core cooling function, avoiding shortening the device's wearing time due to condensation removal, thus ensuring a continuous user experience. When the wearable air conditioner's battery module 110 is charging, the power supply is sufficient and stable. Executing the condensation removal mode at this time solves the condensation accumulation problem without affecting the user's normal wearing and use.

[0058] In one embodiment, such as Figures 1 to 4 As shown, the wearable air conditioner also includes a first fin 104 and a second fin 105.

[0059] The first fin 104 is located at the first end of the temperature controller 101. Since the temperature controller 101 itself has a small area, the first fin 104 increases the contact area of ​​the cooling surface of the temperature controller 101, distributing the cooling energy to a larger skin contact area, thereby efficiently and comfortably cooling the human body. The generated heat is rapidly discharged into the surrounding air by the fan 106 to maintain cooling efficiency.

[0060] The second fin 105 is located at the second end of the temperature controller 101, which is the hot end when the wearable air conditioner is in cooling mode. The second fin 105 increases the contact area of ​​the hot surface of the temperature controller 101, thereby improving heat dissipation efficiency.

[0061] While the fins enhance heat dissipation, they also exacerbate condensation. On the one hand, when the humid air propelled by the fan flows through the dense fins, the flow rate increases, the residence time is prolonged, and the turbulence is enhanced, significantly increasing the probability of water molecules colliding with and adhering to the cold surface. On the other hand, the narrow gaps between the fins easily create a local microenvironment with low temperature and high humidity, further promoting the condensation and accumulation of water vapor.

[0062] In this embodiment, a first humidity sensor 1031 is set at the first end of the temperature controller 101 (the cold end in the cooling state) to monitor the humidity at the first end, and a condensation sensor 1032 is set to monitor the condensation accumulation at the first end. When the humidity detection value of the first humidity sensor 1031 is greater than the threshold and / or a condensation alarm signal is obtained, the wearable air conditioner is controlled to run the condensation removal mode to remove the condensation. This can effectively remove the condensation, eliminate the condensation accumulation, and prevent the condensation accumulation from causing the wearable air conditioner's air duct to become blocked, affecting the heat dissipation of the hot end of the temperature controller, thereby leading to a decrease in cooling efficiency, user discomfort, and potential safety risks. This ensures the normal operation of the wearable air conditioner and the user experience.

[0063] In one embodiment, there are multiple first fins 104; each first fin 104 includes a base that contacts the temperature controller 101, a first humidity sensor 1031 that contacts the base of one of the first fins 104, and a condensation sensor 1032 that contacts the base of one of the first fins 104.

[0064] The base of the first fin 104 is the source of cold energy transfer from the temperature controller 101, and it is also the core area with the lowest temperature, most likely to reach the dew point first, and induce condensation. By placing the first humidity sensor 1031 and the condensation sensor 1032 at the base of the first fin 104, the most source and fastest temperature and humidity changes can be directly sensed, improving the accuracy of condensation detection.

[0065] In one embodiment, when the humidity detection value is greater than a threshold and / or a condensation alarm signal is obtained, the wearable air conditioner is controlled to operate in condensation removal mode to remove condensation.

[0066] In one embodiment, the microcontroller 102 controls the first terminal of the temperature controller 101 to switch to a preset heating mode. Specifically, the microcontroller 102 controls the current direction of the temperature controller 101 to reverse, switching it from a cooling mode to a heating mode, and it operates according to preset heating parameters (such as target temperature, heating power, duration, etc.). At this time, the first terminal changes from the original cold terminal to the hot terminal, heating the surface where condensation has formed, causing it to evaporate and be removed.

[0067] This control strategy removes condensation by heating the temperature controller 101 to raise its temperature and evaporate the condensation.

[0068] like Figures 1 to 4 As shown, the wearable air conditioner also includes a fan 106 electrically connected to the microcontroller 102. The fan 106 is located near the cold end of the temperature controller 101, and its air outlet faces the first fin 104 of the first end of the temperature controller 101, for driving airflow through the first fin 104 to enhance the diffusion of cold energy and blow it onto the user's skin.

[0069] In one embodiment, the wearable air conditioner is equipped with two fans 106, located on either side of the first end of the temperature controller 101, with the air outlets facing the first fin 104 of the first end of the temperature controller 101. In this way, the airflow from both sides covers the first fin 104 from different directions, effectively eliminating the airflow dead zones or uneven cooling problems that may exist when air is supplied from one side, allowing the cooling energy to be more evenly distributed across the entire heat dissipation surface. Simultaneously, the two fans 106 operate together, creating stronger forced convection, which can more quickly remove the cooling energy from the cold-end fins and deliver it to the skin surface, resulting in faster cooling of the device.

[0070] When the humidity detection value exceeds the threshold and / or a condensation alarm signal is received, the fan is controlled to run according to preset parameters (such as speed, air volume, running time, etc.) to enhance airflow inside and on the surface of the wearable air conditioner.

[0071] This control strategy achieves forced convection by operating a fan, carrying away the saturated humid air from the condensation surface, thereby accelerating the natural evaporation of the condensation and clearing it. In one embodiment, the wearable air conditioner also includes a second humidity sensor 108, which is disposed on the surface of the housing and used to collect ambient humidity information.

[0072] The second humidity sensor 108 is electrically connected to the microcontroller 102. The microcontroller 102 generates a switching control signal for the temperature controller based on the detection results of the first humidity sensor 1031 and the second humidity sensor 108, and / or the detection results of the condensation sensor 1032.

[0073] The second humidity sensor 108 is used to collect environmental humidity information. The real-time environmental humidity information it provides can serve as a benchmark for judging whether the local humidity has increased, thereby reducing the false alarm rate.

[0074] When the humidity detection value of the first humidity sensor 1031 is greater than the humidity detection value of the second humidity sensor 108, it indicates that the humidity at the first end (cold end) of the temperature controller 101 has increased and exceeds the ambient humidity. And / or, when a condensation alarm signal is detected by the condensation sensor 1032, a switching control signal is generated to switch the temperature controller 101 to heating mode (e.g., applying a reverse current to the temperature controller 101), driving the temperature controller 101 into the heating state. At this time, the first end changes from the original cold end to the hot end, heating the surface where condensation has formed, causing it to evaporate and be removed.

[0075] In one embodiment, the microcontroller 102 is configured to generate switching control signals for the temperature controller 101 and the fan based on the detection results of the first humidity sensor 1031 and the second humidity sensor 108, and / or the detection result of the condensation sensor 1032. For example, when the humidity detection value of the first humidity sensor 1031 is greater than the humidity detection value of the second humidity sensor 108 and / or a condensation alarm signal is obtained from the condensation sensor 1032, a switching control signal is generated to switch the temperature controller 101 to heating mode (e.g., applying a reverse current to the temperature controller 101), driving the temperature controller 101 into the heating state, and simultaneously controlling the fan to operate according to preset parameters (e.g., speed, airflow, running time, etc.) to enhance airflow inside and on the surface of the wearable air conditioner.

[0076] Forced convection is achieved by running a fan, which removes the saturated humid air from the condensation surface, thereby accelerating the natural evaporation of the condensation and clearing it away.

[0077] In one embodiment, the second humidity sensor 108 is located around the fan 106. The fan periphery is typically the air intake of a wearable air conditioner. Placing the second humidity sensor 108 at this air intake location ensures that the air it samples is "fresh" ambient air drawn in by the device and not disturbed by heat exchange processes of internal working components (such as the hot end or the operating cold end of the temperature controller 101), thereby obtaining a true and accurate ambient humidity reference.

[0078] Furthermore, due to the continuous airflow at the air intake, the air flowing through the second humidity sensor 108 is rapidly refreshed. This allows the second humidity sensor 108 to quickly detect sudden changes in ambient humidity when the user moves between different humidity environments (e.g., from a dry air-conditioned room to a humid outdoor environment). The microcontroller 102 can immediately obtain the updated environmental baseline value and quickly reassess whether the local microenvironment humidity monitored by the first humidity sensor 1031 poses a risk of condensation, thereby enabling earlier generation or adjustment of switching control signals to achieve proactive anti-condensation.

[0079] In one embodiment, a receiving cavity isolated from the fan 106 is provided around the fan 106 to house the second humidity sensor 108. This allows for precise positioning and reliable limiting of the second humidity sensor 108 using the physical structure of the receiving cavity, ensuring its stable position during device operation or movement. Furthermore, by housing the second humidity sensor 108 in an independent space isolated from the fan's active airflow, the forced airflow, pressure fluctuations, and potential internal backflow air generated during fan 106 operation are effectively prevented from directly contacting the second humidity sensor 108, thus ensuring the accuracy of the environmental humidity data collected by the second humidity sensor 108. This wearable air conditioner can serve as a neck-hanging air conditioner, providing a physical basis for condensation detection and active removal using the above-mentioned configuration. The condensation detection and active removal functions of the neck-hanging air conditioner prevent condensation accumulation from blocking the air ducts, affecting heat dissipation at the temperature controller's hot end, thereby reducing cooling efficiency, causing user discomfort, and potential safety risks, thus ensuring the normal operation of the neck-hanging air conditioner and the user experience.

[0080] In one embodiment, this application also provides a control method for a wearable air conditioner, such as... Figure 6 As shown, it includes: Step 402: Obtain at least one of the humidity detection value of the first humidity sensor and the detection signal of the condensation sensor; the detection signal includes a condensation alarm signal emitted by the condensation sensor when it detects condensation on the surface.

[0081] Specifically, the first humidity sensor 1031 is disposed at the first end of the temperature controller 101 and is used to infer the formation of condensation at the first end based on the humidity detection value at the first end.

[0082] The condensation sensor 1032 is located at the first end of the temperature controller 101. According to the working principle of the condensation sensor 1032, the condensation sensor 1032 directly detects the presence of condensation through physical contact.

[0083] When the first end is the cold end, the microcontroller 102 can determine whether condensation exists on the temperature controller 101 by monitoring at least one of the humidity detection values ​​of the first humidity sensor 1031 and the detection signals of the condensation sensor 1032. For example, if the humidity detection value of the first humidity sensor 1031 is greater than a threshold, the microcontroller 102 determines that condensation exists on the temperature controller 101. This threshold is the humidity critical value at which condensation begins to form on the surface under normal operating environmental conditions of the wearable air conditioner, and can be determined experimentally.

[0084] When the detection signal of the condensation sensor 1032 is a condensation alarm signal issued when condensation is detected on the surface (such as a high-level signal), it can be determined that the amount of condensation is large. Thus, by combining the humidity detection value of the first humidity sensor 1031 and the detection signal of the condensation sensor 1032, the different degrees of condensation severity at the first end of the temperature controller 101 can be determined.

[0085] Step 404: When the humidity detection value is greater than the threshold and / or a condensation alarm signal is obtained, control the wearable air conditioner to run the condensation removal mode to remove the condensation.

[0086] In one embodiment, when the detected humidity value is greater than a set threshold, it can be inferred that the temperature controller 101 has a small amount of condensation, which causes the humidity to change.

[0087] In one embodiment, when the detection signal of the condensation sensor 1032 is a condensation alarm signal, it can be inferred that there is a lot of condensation at the first end of the temperature controller 101, which triggers a short circuit in the condensation sensor 1032.

[0088] In one embodiment, when the humidity detection value is greater than the threshold, it can be determined as a first degree of condensation. When a condensation alarm signal is obtained from the condensation sensor 1032, it can be determined as a second degree of condensation.

[0089] Specifically, when the detected humidity value exceeds a set threshold, it can be inferred that a small amount of condensation exists at the temperature controller 101, causing a change in humidity. At this time, because the amount of condensation is small, it is insufficient to trigger a short circuit in the condensation sensor 1032 to issue a condensation alarm signal. However, when the condensation sensor 1032 issues a condensation alarm signal, it can be determined that there is a significant amount of condensation at the first terminal of the temperature controller 101, triggering a short circuit in the condensation sensor 1032 and issuing a condensation alarm signal.

[0090] Combining the humidity detection value of the first humidity sensor 1031 and the detection signal of the condensation sensor 1032 can improve the accuracy of condensation detection. For example, if the condensation sensor 1032 outputs a condensation alarm signal, but the humidity detection value of the first humidity sensor 1031 is not less than a set threshold, it can be determined that the detection result of the condensation sensor 1032 is abnormal.

[0091] When the humidity detection value is greater than the threshold and / or a condensation alarm signal is obtained, the wearable air conditioner is controlled to run the condensation removal mode to remove the condensation at the first end of the temperature controller 101.

[0092] Specifically, the microcontroller 102 controls the relevant devices to operate in a condensation removal mode to remove condensation. For example, the microcontroller 102 controls the first terminal of the temperature controller 101 to switch to a preset heating mode and simultaneously adjusts the fan to enhance ventilation, thereby achieving active evaporation and removing condensation, restoring the surface of the wearable air conditioner to dryness.

[0093] The aforementioned control method for a wearable air conditioner involves setting a first humidity sensor 1031 and a condensation sensor 1032 at the first end of the temperature controller 101. When the humidity detection value of the first humidity sensor 1031 exceeds a threshold, and / or when the detection signal from the condensation sensor 1032 is a condensation alarm, the wearable air conditioner is controlled to operate in a condensation removal mode to clear the condensation. This allows for proactive monitoring of the condensation at the first end of the temperature controller 101 and proactive removal of condensation, preventing condensation buildup from blocking the air ducts of the wearable air conditioner, affecting heat dissipation at the hot end of the temperature controller, thus reducing cooling efficiency, causing user discomfort, and posing potential safety risks. This ensures the normal operation of the wearable air conditioner and a positive user experience.

[0094] In one embodiment, the condensation removal mode includes at least one of the following modes: The first type: The first end of the temperature controller 101 of the wearable air conditioner generates heat; The second type: The fan of the wearable air conditioner rotates 106 times.

[0095] Therefore, the condensation removal modes include the following three: First condensation removal mode: Heating at the first end of the temperature controller 101 of the wearable air conditioner.

[0096] Specifically, when the humidity detection value exceeds the threshold and / or a condensation alarm signal is received, the current direction of the control temperature controller 101 is reversed, causing the first end to switch from cooling mode to heating mode, and operate according to preset heating parameters (such as target temperature, heating power, duration, etc.). At this time, the first end changes from the original cold end to the hot end, heating the surface where condensation has formed, causing it to evaporate and be removed.

[0097] This condensation removal mode removes condensation by heating the temperature controller 101 to raise its temperature and evaporate the condensation.

[0098] The second condensation removal mode: the wearable air conditioner's fan 106 rotates.

[0099] Specifically, when the humidity detection value is greater than the threshold and / or a condensation alarm signal is obtained, the fan 106 is controlled to run according to preset parameters (such as speed, air volume, running time, etc.) to enhance the airflow inside and on the surface of the wearable air conditioner.

[0100] This condensation removal mode achieves forced convection by operating fan 106, which removes saturated humid air from the condensation surface, thereby accelerating the natural evaporation of the condensation and thus removing it.

[0101] The third condensation removal mode: the first end of the wearable air conditioner's temperature controller 101 heats up, and the wearable air conditioner's fan 106 rotates.

[0102] Specifically, when the humidity detection value exceeds the threshold and / or a condensation alarm signal is received, the first terminal of the temperature controller 101 is switched to heating mode and operates according to preset heating parameters, while the fan 106 is controlled to operate according to preset ventilation parameters. That is, the two work together: the temperature controller 101 provides the heat required for evaporation, and the fan provides the airflow to remove water vapor. Thus, the condensation is efficiently evaporated and discharged outside the wearable air conditioner, restoring the temperature controller 101 to a dry state.

[0103] In one embodiment, when the humidity detection value is greater than a threshold and / or a condensation alarm signal is received, the wearable air conditioner is controlled to operate in a condensation removal mode to remove condensation, including: If the humidity detection value is greater than the threshold and / or a condensation alarm signal is obtained, it is determined whether the first terminal of the temperature controller is in a cooling state. If the first terminal of the temperature controller is not in cooling mode, the wearable air conditioner is controlled to run in condensation removal mode to remove condensation.

[0104] Specifically, based on the humidity detection value exceeding the threshold and / or the acquisition of a condensation alarm signal, the cooling status of the first terminal of the temperature controller 101 is further detected. If the first terminal of the temperature controller 101 is not in a cooling state, the wearable air conditioner is controlled to operate a condensation removal mode to remove condensation. That is, when the humidity detection value detected by the first humidity sensor 1031 exceeds the threshold and / or a condensation alarm signal is acquired from the condensation sensor 1032, the condensation removal mode is not operated if the first terminal of the temperature controller 101 is in a cooling mode. When the first terminal of the temperature controller 101 stops operating in the cooling mode and is in a standby state, the temperature controller 101 of the wearable air conditioner can be controlled to operate according to preset heating parameters, and / or the fan 106 of the wearable air conditioner can be controlled to operate according to preset ventilation parameters to remove condensation.

[0105] In one embodiment, during the standby phase after the wearable air conditioner has been powered on but before cooling is activated, the humidity detection value of the first humidity sensor 1031 and / or the detection signal of the condensation sensor 1032 can be detected. If the humidity detection value is greater than a threshold and / or a condensation alarm signal is detected, the wearable air conditioner is controlled to run a condensation removal mode to remove condensation. This ensures that the first end of the temperature controller 101 is dry before cooling is activated, avoiding problems such as decreased cooling efficiency, uneven cold transfer, or damp user contact surfaces caused by initial condensation shortly after the cooling mode starts running, thus improving the user experience.

[0106] In one embodiment, in the standby state after the wearable air conditioner stops cooling, the humidity detection value of the first humidity sensor 1031 and / or the detection signal of the condensation sensor 1032 are detected. If the humidity detection value is greater than a threshold and / or a condensation alarm signal is obtained, the wearable air conditioner is controlled to operate a condensation removal mode to remove condensation. This ensures that condensation generated during cooling operation is actively removed after the temperature controller 101 stops cooling. This prevents condensation from remaining in the wearable space for a long time when it is not in use, which could lead to corrosion, mold growth, or affect sensor accuracy, thus preparing the wearable air conditioner for the next cooling start-up.

[0107] Meanwhile, when the humidity detection value is greater than the threshold and / or a condensation alarm signal is obtained, the wearable air conditioner will only be controlled to run the condensation removal mode when the first end of the temperature controller is not in a cooling state. This can effectively prevent the cooling operation from being interrupted due to condensation removal, thereby avoiding affecting the user experience.

[0108] In one embodiment, when the humidity detection value is greater than a threshold and / or a condensation alarm signal is received, the wearable air conditioner is controlled to operate in a condensation removal mode to remove condensation, including: If the humidity detection value of the first humidity sensor 1031 is greater than the threshold and / or a condensation alarm signal is obtained from the condensation sensor 1032, it is determined whether the wearable air conditioner is in wearable mode. If the wearable air conditioner is not in wearable mode, control the wearable air conditioner to run the condensation removal mode to remove condensation.

[0109] Specifically, based on the humidity detection value of the first humidity sensor 1031 exceeding the threshold and / or the acquisition of a condensation alarm signal from the condensation sensor 1032, the wearing status of the wearable air conditioner is further detected. If the wearable air conditioner is not in a wearing state, the wearable air conditioner is controlled to operate a condensation removal mode to remove condensation. That is, if the wearable air conditioner is in a wearing state, but the humidity detection value exceeds the threshold and / or a condensation alarm signal is acquired, the condensation removal mode is not operated. When it is detected that the wearable air conditioner is not in a wearing state, the temperature controller 101 of the wearable air conditioner can be controlled to operate according to preset heating parameters, and / or the fan of the wearable air conditioner can be controlled to operate according to preset parameters to remove condensation.

[0110] In one embodiment, an infrared sensor and / or a capacitive sensor are disposed on the skin contact surface of the wearable air conditioner to detect the wearing status of the wearable air conditioner. The infrared sensor and the capacitive sensor are electrically connected to the microcontroller 102.

[0111] Specifically, infrared sensors can be used to detect infrared radiation of specific wavelengths. When the wearable air conditioner is worn close to the skin, the infrared sensor receives infrared radiation emitted from the skin surface (related to body temperature). When the device is removed from the skin (e.g., placed on a table), the infrared signal received by the sensor abruptly changes to the radiation from environmental objects, whose intensity and characteristics differ significantly from those of human skin. The microcontroller 102 can distinguish whether the wearable air conditioner is in contact with the skin or detached by monitoring the intensity, stability, or specific waveform characteristics of the infrared sensor signal.

[0112] The capacitive sensor electrodes form a tiny capacitor with the skin. When the wearable air conditioner is in close contact with the skin, the human body significantly alters the electric field distribution between the capacitive sensor electrodes, causing a specific change in its capacitance value. When the device is removed from the skin, the capacitance value returns to its baseline state. The microcontroller 102 determines whether the wearable air conditioner has made effective contact with the human skin by detecting the amount of change in capacitance or a specific threshold.

[0113] If the humidity detection value of the first humidity sensor 1031 is greater than the threshold and / or a condensation alarm signal is obtained from the condensation sensor 1032, then the infrared sensor and / or capacitive sensor detect whether the wearable air conditioner is in wearable mode; if the wearable air conditioner is not in wearable mode, then the wearable air conditioner is controlled to run the condensation removal mode to remove condensation.

[0114] This effectively prevents uncomfortable hot air or abnormal operating noise caused by the condensation removal mode when users wear the wearable air conditioner, thus improving the user experience.

[0115] In one embodiment, when the humidity detection value is greater than a threshold and / or a condensation alarm signal is received, the wearable air conditioner operates a condensation removal mode to remove condensation, including: If the humidity detection value of the first humidity sensor 1031 is greater than the threshold and / or a condensation alarm signal is obtained from the condensation sensor 1032, then it is determined whether the first end of the temperature controller is in a cooling state and whether it is in a wearable state. If the first terminal of the temperature controller is not in cooling mode and the wearable air conditioner is not in wearable mode, then control the wearable air conditioner to run the condensation removal mode to remove condensation.

[0116] Specifically, based on the humidity detection value exceeding the threshold and / or the acquisition of a condensation alarm signal, the wearable air conditioner's wearing status and the cooling status of the first terminal of the temperature controller are further detected. If the wearable air conditioner is not in a wearing state and the first terminal of the temperature controller is not in a cooling state, the wearable air conditioner is controlled to operate a condensation removal mode to remove condensation. That is, when the humidity detection value exceeds the threshold and / or a condensation alarm signal is acquired, if the wearable air conditioner is in a wearing state or the first terminal of the temperature controller is in a cooling state, the condensation removal mode is not operated. Only when the wearable air conditioner is not in a wearing state and the first terminal of the temperature controller is not in a cooling state can the wearable air conditioner temperature controller 101 be controlled to operate according to preset heating parameters, and / or the wearable air conditioner fan be controlled to operate according to preset ventilation parameters to remove condensation.

[0117] This effectively prevents the cooling operation from being interrupted due to condensation removal, and also effectively prevents uncomfortable hot air or abnormal operating noise caused by condensation removal when the user is wearing the wearable air conditioner, thus improving the user experience.

[0118] In one embodiment, such as Figures 1 to 5 As shown, the wearable air conditioner also includes a battery module 110 electrically connected to the microcontroller 102. When the humidity detection value is greater than the threshold and / or a condensation alarm signal is obtained, the wearable air conditioner is controlled to run a condensation removal mode to remove condensation. This includes: when the humidity detection value is greater than the threshold and / or a condensation alarm signal is obtained, the battery status of the battery module 110 is obtained; when the battery module is in a charging state, the wearable air conditioner is controlled to run a condensation removal mode to remove condensation.

[0119] Therefore, when a condensation risk or condensation alarm signal is detected, if the wearable air conditioner's battery module 110 is in a discharging state (i.e., not charging), the high-energy-consuming condensation removal mode (such as TEC reverse high-power heating) will be temporarily suspended. This prioritizes ensuring the battery power used for the core cooling function, avoiding shortening the device's wearing time due to condensation removal, thus ensuring a continuous user experience. When the wearable air conditioner's battery module 110 is charging, the power supply is sufficient and stable. Executing the condensation removal mode at this time solves the condensation accumulation problem without affecting the user's normal wearing and use.

[0120] In one embodiment, when the humidity detection value is greater than a threshold, the wearable air conditioner is controlled to operate in a condensation removal mode to remove condensation, including: Obtain the difference between the humidity detection value and the preset humidity reference value; When the absolute value of the difference is greater than the first preset value, the wearable air conditioner is controlled to run the condensation removal mode to remove condensation; the threshold is the sum of the preset humidity reference value and the first preset value.

[0121] The preset humidity reference value can be the humidity detection value collected and recorded when the wearable air conditioner completes its initial startup or starts running the cooling mode, or it can be the humidity reference value under normal conditions without condensation. During the operation of the cooling mode, the difference between the humidity detection value and the preset humidity reference value is calculated. If the absolute value of the difference is greater than a first preset value, this is equivalent to the humidity detection value being greater than a threshold (the threshold is equal to the sum of the preset humidity reference value and the first preset value). In this case, the wearable air conditioner is controlled to run the condensation removal mode to remove condensation. At this time, it can be inferred that the humidity of the cold surface of the temperature controller 101 has changed significantly during operation, and condensation may exist on the cold surface of the temperature controller 101.

[0122] This is a relative determination method. When the wearable air conditioner completes its initial startup or starts running in cooling mode, the humidity value collected by the first humidity sensor 1031 can be used as a preset humidity reference value. Alternatively, the system can set the humidity detection value under normal conditions without condensation as the preset humidity reference value. Simultaneously, a first preset value is set based on a threshold value, which is the difference between the threshold value and the preset humidity reference value.

[0123] In this scenario, only a first humidity sensor 1031 needs to be set up. By monitoring the change in humidity of the first humidity sensor 1031 relative to a preset humidity reference value, it can be determined that the humidity of the cold surface of the temperature controller 101 has changed significantly during operation. This method determines the relative change of the current humidity of the first humidity sensor relative to the preset humidity reference (power-on initialization, start of cooling mode, or normal non-condensation state). Compared to the absolute determination method of directly judging whether the humidity detection value is greater than a threshold, this method is more in line with physical principles, has a lower false alarm rate, and provides more accurate warnings.

[0124] In one embodiment, such as Figures 1 to 5As shown, the wearable air conditioner also includes a second humidity sensor 108 disposed on the surface of the wearable air conditioner housing. The second humidity sensor 108 is used to collect ambient humidity values. That is, in this embodiment, a first humidity sensor 1031 is disposed at the first end of the temperature controller 101 of the wearable air conditioner, which can be used to directly detect the humidity at the first end of the temperature controller 101. A second humidity sensor 108 is also disposed on the surface of the wearable air conditioner housing, which can be used to detect the actual humidity of the environment in which the wearable air conditioner is located. In this way, the ambient humidity value collected by the second humidity sensor 108 can be used as a comparison reference for the humidity detection value of the first humidity sensor 1031, thereby improving the reliability of the humidity detection value of the first humidity sensor 1031.

[0125] In this embodiment, when the humidity detection value is greater than a threshold, the wearable air conditioner is controlled to operate in condensation removal mode to remove condensation, including: Obtain the difference between the measured humidity value and the ambient humidity value; When the absolute value of the difference is greater than the second preset value, the wearable air conditioner is controlled to run the condensation removal mode to remove condensation. The threshold is the sum of the ambient humidity value and the second preset value.

[0126] The first humidity sensor 1031 is attached to or adjacent to the first end (cold end) of the temperature controller 101 to monitor the humidity information of the temperature controller 101. The second humidity sensor 108 is disposed on the surface of the housing and exposed to circulating air to monitor the ambient humidity of the wearable air conditioner.

[0127] By setting a first humidity sensor 1031 and a second humidity sensor 108, the humidity change of the first humidity sensor 1031 relative to the humidity of the second humidity sensor 108 can be monitored. Simultaneously, the sum of the ambient humidity value and a second preset value is set as a threshold.

[0128] The system acquires the difference between the detected humidity value and the ambient humidity value. When the absolute value of the difference is greater than a second preset value (equivalent to the humidity value of the first humidity sensor being greater than a threshold), the wearable air conditioner is controlled to operate in condensation removal mode to clear condensation. This method determines the relative change of the current humidity of the first humidity sensor relative to the ambient humidity. This is more in line with the physical characteristics of condensation formation, where the local humidity is significantly higher than the ambient humidity. Compared to the absolute determination method of whether the detected humidity value is greater than the threshold, this method is more in line with physical principles, has a lower false alarm rate, and provides more accurate warnings.

[0129] In one embodiment, when the humidity detection value is greater than a threshold and / or a condensation alarm signal is received, the wearable air conditioner is controlled to operate in a condensation removal mode to remove condensation, including: If the humidity detection value is greater than the threshold, the first terminal of the temperature controller is controlled to heat at the first heating temperature. Upon receiving a condensation alarm signal, the first terminal of the temperature controller is controlled to heat at a second heating temperature, which is higher than the first heating temperature.

[0130] Specifically, when the humidity detection value is greater than the threshold and / or a condensation alarm signal is obtained, a reverse current is applied to the temperature controller 101 to drive the first terminal of the temperature controller 101 into the heating state.

[0131] Specifically, when the humidity detection value exceeds a threshold, the first terminal of the wearable air conditioner's temperature controller 101 is controlled to heat at a first heating temperature. If condensation is detected based on the humidity detection value (usually not severe), the first terminal of the temperature controller 101 is switched to the first heating temperature for heating; this temperature typically corresponds to low power consumption. Based on this temperature, the temperature controller 101 is heated to gently raise the temperature of the cold end, increasing its surface temperature and thus clearing surface condensation.

[0132] Upon receiving a condensation alarm signal, the first terminal of the wearable air conditioner's temperature controller 101 is controlled to heat at a second heating temperature, which is higher than the first heating temperature. When the condensation sensor 1032 issues a condensation alarm signal, the condensation situation is relatively more severe. At this time, the first terminal of the temperature controller 101 is controlled to heat at the second heating temperature. The power consumption corresponding to the second heating temperature is usually high, and the second heating temperature is significantly higher than the first heating temperature, so as to rapidly and strongly heat the cold end and fins, thereby accelerating the evaporation of condensate droplets and eliminating condensation on the surface of the first terminal.

[0133] When the humidity detection value exceeds the threshold and / or a condensation alarm signal is received, the wearable air conditioner is controlled to operate in condensation removal mode to remove condensation, including: If the humidity detection value is greater than the threshold, the wearable air conditioner's fan 106 is controlled to rotate at the first speed. Upon receiving a condensation alarm signal, the wearable air conditioner's fan 106 is controlled to rotate at a second speed, which is higher than the first speed.

[0134] Specifically, when the humidity detection value exceeds a threshold, the wearable air conditioner's fan 106 is controlled to rotate at a first speed. If condensation is detected based on the humidity detection value, and the condensation is generally not severe, the fan 106 is controlled to rotate at the first speed, which typically corresponds to low power consumption. Controlling the fan 106 based on this first speed increases the airflow across the first end surface. This enhanced airflow continuously carries away the more humid air near the first end, replacing it with relatively dry ambient air, thereby accelerating the natural evaporation of condensation.

[0135] Upon receiving a condensation alarm signal, the wearable air conditioner's fan 106 is controlled to rotate at a second speed, which is higher than the first speed. When the condensation sensor 1032 issues a condensation alarm signal, the condensation situation is relatively more severe. At this time, the fan 106 is controlled to rotate at the second speed. The power consumption corresponding to the second speed is typically high, and the second speed is significantly higher than the first speed. This increases the airflow across the first end surface, and the enhanced airflow continuously carries away the more humid air near the first end, replacing it with relatively dry ambient air, thereby accelerating the rapid evaporation of condensation.

[0136] In one embodiment, when the humidity detection value is greater than a threshold and / or a condensation alarm signal is received, the wearable air conditioner is controlled to operate in a condensation removal mode to remove condensation, including: When the humidity detection value is greater than the threshold, the first terminal of the temperature controller 101 of the wearable air conditioner is controlled to heat at the first heating temperature, and the fan 106 of the wearable air conditioner is controlled to rotate at the first speed. Upon receiving a condensation alarm signal, the first terminal of the wearable air conditioner's temperature controller 101 is controlled to heat at a second heating temperature, and the wearable air conditioner's fan 106 is controlled to rotate at a second speed. The second heating temperature is higher than the first heating temperature, and the second speed is higher than the first speed.

[0137] In this embodiment, when the humidity detection value is greater than the threshold, it can be determined as a first-degree condensation state. When the condensation alarm signal of the condensation sensor 1032 is obtained, it can be determined as a second-degree condensation state.

[0138] Specifically, when the humidity detection value exceeds a threshold, a reverse current is applied to the temperature controller 101, driving its first terminal to enter a heating state. The first terminal of the temperature controller 101 heats at a first heating temperature, while simultaneously controlling the fan 106 to rotate at a first speed. Heating provides stable evaporation power, and ventilation ensures continuous dehumidification. This method achieves active condensation removal in a low-power manner.

[0139] Upon receiving a condensation alarm signal, a reverse current is applied to the temperature controller 101, driving its first terminal to enter heating mode. The first terminal of the temperature controller 101 heats at a higher second heating temperature, while simultaneously controlling the fan 106 to rotate at a higher second speed. This method achieves condensation removal by operating the heating mode with relatively high power consumption.

[0140] In this embodiment, different heating temperatures of the temperature controllers and different fan speeds are matched according to different condensation levels to clear condensation, thereby improving the intelligence of the wearable air conditioner and reducing energy consumption.

[0141] A method for controlling a wearable air conditioner, such as Figure 7 As shown, it includes: Step 502: Obtain the humidity detection value of the first humidity sensor, the ambient humidity value of the second humidity sensor, and the detection signal of the condensation sensor.

[0142] Step 504: Determine whether the detection signal from the condensation sensor is a condensation alarm signal. If yes, proceed to step 506; otherwise, proceed to step 508.

[0143] Step 506: Control the first terminal of the wearable air conditioner's temperature controller to heat at the second heating temperature, and control the wearable air conditioner's fan to rotate at the second speed. Following this step, proceed to step 512.

[0144] Step 508: Determine if the humidity detection value is greater than the ambient humidity value. If yes, proceed to step 510; otherwise, return to step 502 to continue data collection.

[0145] Step 510: Control the first terminal of the wearable air conditioner's temperature controller to heat at a first heating temperature, and control the wearable air conditioner's fan to rotate at a second speed; wherein the second heating temperature is higher than the first heating temperature, and the second speed is higher than the first speed. After step 510, execute step 512.

[0146] Step 512: Determine whether the detection signal of the condensation sensor is a condensation alarm signal after the condensation is cleared. If yes, continue to step 506; otherwise, proceed to step 514.

[0147] Step 514: Check if the humidity reading is lower than the ambient humidity value. If not, proceed to step 510; if yes, proceed to step 516 to exit the condensation removal mode.

[0148] After the wearable air conditioner operates in condensation removal mode, it further detects whether the condensation has been removed via condensation sensor 1032. Once condensation sensor 1032 detects that the condensation has been removed, it further checks whether the humidity detection value of the first humidity sensor 1031 has returned to below the ambient humidity level. If the humidity value is still above the threshold, it indicates that the high humidity environment causing the condensation may not have improved, and the wearable air conditioner can continue operating in condensation removal mode. If the humidity detection value is below the ambient humidity level, it indicates that the condensation has been removed and the humidity has returned to normal, then the condensation removal process is exited. Specifically, the temperature controller 101 is turned off to operate in heating mode, and the fan 106 is turned off.

[0149] In this embodiment, the humidity detection value of the first humidity sensor 1031, the ambient humidity value of the second humidity sensor 108, and the condensation detection result of the condensation sensor 1032 are used as judgment parameters to determine different degrees of condensation severity and match different intensity removal methods, thereby improving the intelligence level of the wearable air conditioner and reducing energy consumption. After condensation occurs, the condensation situation is further detected to ensure the effectiveness of removal and realize a closed loop of condensation removal control.

[0150] This wearable air conditioner control method can be applied to neck-hook air conditioners, enabling condensation detection and active removal. It prevents condensation buildup from blocking the air ducts, affecting heat dissipation at the temperature controller's hot end, thus reducing cooling efficiency, causing user discomfort, and posing potential safety risks. This ensures the normal operation of the neck-hook air conditioner and a good user experience.
