Control method of wearable air conditioner, wearable air conditioner, and storage medium

Abstract

The application provides a wearable air conditioner control method, a wearable air conditioner and a storage medium. The method increases the temperature of a cold guide from a first temperature by reducing the working power of a semiconductor refrigerator when the temperature of the cold guide reaches the first temperature, and decreases the temperature of the cold guide from a second temperature by increasing the working power of the semiconductor refrigerator when the temperature of the cold guide rises to the second temperature. In this way, the temperature of the cold guide rises from the first temperature to the second temperature and then decreases, reactivating the cold receptors on the skin, allowing the user to feel cool, and overcoming the skin temperature adaptation phenomenon. At the same time, since the user can feel cool at the current gear, the need for the user to increase the gear to run the wearable air conditioner at a high gear is reduced, and the endurance of the wearable air conditioner is prolonged.

Description

Technical Field

[0001] This application relates to the field of portable temperature control devices, and in particular to a control method for a wearable air conditioner, a wearable air conditioner, and a storage medium. Background Technology

[0002] With the development of thermoelectric cooling (TEC) technology, TEC technology has been applied to the wearable field, giving rise to portable and wearable air conditioners such as neckband air conditioners. These are popular with users due to their portability and cooling capabilities.

[0003] However, due to the temperature adaptation phenomenon of human skin, even when the temperature of a semiconductor cooler is constant, the user's subjective "cold sensation" will gradually decrease, leading to a decline in the experience. Current technology cannot solve this physiological problem. Summary of the Invention

[0004] To address the existing technical problems, this application provides a control method for a wearable air conditioner that can overcome skin temperature adaptation, a wearable air conditioner, and a storage medium.

[0005] In a first aspect, a control method for a wearable air conditioner is provided, comprising: acquiring the current temperature of a cooling component of the wearable air conditioner; when the current temperature of the cooling component reaches a first temperature, controlling a reduction in the operating power of a thermoelectric cooler to cause the current temperature of the cooling component to rise from the first temperature; when the current temperature of the cooling component rises to a second temperature, controlling an increase in the operating power of the thermoelectric cooler to cause the current temperature of the cooling component to fall from the second temperature; wherein the second temperature is higher than the first temperature.

[0006] Secondly, a wearable air conditioner is provided, comprising: a semiconductor cooler, a microcontroller, a temperature sensor, a power drive circuit, and a cooling conductor; the cold surface of the semiconductor cooler is mounted on the cooling conductor; the temperature sensor is disposed close to the cooling conductor and is used to collect the current temperature of the cooling conductor; the temperature sensor is connected to the microcontroller; the microcontroller is connected to the input terminal of the power drive circuit, and the output terminal of the power drive circuit is connected to the semiconductor cooler; the microcontroller includes a processor and a memory connected to the processor, the memory storing a computer program executable by the processor, and the computer program, when executed by the processor, implements the steps of the wearable air conditioner control method of the above embodiment.

[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 increases the temperature of the cooling component by reducing the operating power of the thermoelectric cooler when the temperature of the cooling component reaches a first temperature, and then increasing the operating power of the thermoelectric cooler when the temperature of the cooling component reaches a second temperature. This causes the temperature of the cooling component to rise from the first temperature to the second temperature and then decrease again, reactivating the cold receptors on the skin and allowing the user to feel coolness, overcoming the skin temperature adaptation phenomenon. Simultaneously, because the user can feel coolness at the current setting, the need for the user to adjust the setting to a higher level reduces the need for the wearable air conditioner to operate at a higher speed, thus extending the battery life of the wearable air conditioner.

[0009] The wearable air conditioner and storage medium provided in the above embodiments belong to the same concept as the corresponding wearable air conditioner control method embodiments, and thus have the same technical effects as the corresponding wearable air conditioner control method embodiments, which will not be repeated here.

[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 (the heat-absorbing end) and the other end to heat up (the heat-releasing end). With the development of thermoelectric cooler (TEC) technology, its application in wearable devices has led 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] A type of wearable air conditioner, such as Figure 1 As shown, the system includes: a thermoelectric cooler (TEC) 101, a microcontroller 102, a temperature sensor 103, a power drive circuit 104, and a cooling conductor 105. The cold side of the TEC 101 is typically mounted on the cooling conductor 105, which provides structural support for the TEC 101. Simultaneously, the TEC 101 itself has a small area, allowing it to distribute coolness to a larger skin contact area via the cooling conductor 105, thus efficiently and comfortably cooling the human body.

[0024] In some embodiments, the wearable air conditioner further includes a heat dissipation system. In one example, the heat dissipation system may include a heat sink and a fan. The hot side of the thermoelectric cooler 101 is mounted on the heat sink, and the fan rapidly dissipates the generated heat into the surrounding air to maintain cooling efficiency.

[0025] Taking a neck-mounted air conditioner as an example, the cooling component 105 is usually two metal sheets (such as aluminum sheets) located on the inside of the neck-mounted device, which can directly contact the skin to achieve cooling.

[0026] Wearable air conditioners can also be made into other wearable forms, such as wearable clothing air conditioners and localized strap air conditioners. This is achieved by integrating multiple semiconductor coolers 101 into key areas of the clothing (such as the chest, back, and abdomen) or placing multiple semiconductor coolers 101 inside the straps, which are then strapped to the back or other areas during use. The corresponding outer surface integrates a heat dissipation module (heat dissipation fins and a fan). Cooling is achieved by direct contact between the cooling element 105 and the skin to cool the core area of ​​the torso.

[0027] A temperature sensor 103 is positioned close to the cooling conductor 105 to collect the current temperature of the cooling conductor 105. The temperature sensor 103 is connected to a microcontroller 102 and sends the collected current temperature to the microcontroller 102. The output of the microcontroller 102 is connected to the input of a power drive circuit 104, and the output of the power drive circuit 104 is connected to the thermoelectric cooler 101. The microcontroller 102 determines a power control strategy based on the current temperature and sends a corresponding control signal to the power drive circuit 104 according to the power control strategy. The power drive circuit 104 responds to the control signal and drives the thermoelectric cooler 101 to adjust its operating power.

[0028] Specifically, the microcontroller 102 collects the current temperature of the cooling component 105 of the wearable air conditioner through the temperature sensor 103; when the current temperature of the cooling component 105 reaches a first temperature, it controls to reduce the operating power of the semiconductor cooler 101 so that the current temperature of the cooling component 105 rises from the first temperature; when the current temperature of the cooling component 105 rises to a second temperature, it controls to increase the operating power of the semiconductor cooler 101 so that the current temperature of the cooling component 105 falls from the second temperature; wherein, the second temperature is higher than the first temperature.

[0029] Furthermore, the microcontroller 102 may specifically be a chip with model numbers CW32L083, MM32L0130, or STM32G030.

[0030] The wearable air conditioner provided in this application raises the temperature of the cooling element 105 from the first temperature by reducing the operating power of the semiconductor cooler 101 when the temperature of the cooling element 105 reaches the first temperature, and then lowers the temperature of the cooling element 105 from the second temperature when the temperature of the cooling element 105 rises to the second temperature. This causes the temperature of the cooling element 105 of the wearable air conditioner to rise from the first temperature to the second temperature and then fall again, reactivating the cold receptors on the skin and allowing the user to feel coolness, overcoming the skin temperature adaptation phenomenon. Simultaneously, because the user can continuously feel coolness at the current setting, the need for the user to adjust the setting to a higher level reduces the need for the wearable air conditioner to operate at a higher level, thus extending the battery life of the wearable air conditioner.

[0031] In another embodiment of this application, a control method for a wearable air conditioner is provided, applicable to, for example... Figure 1 The microcontroller 102 shown is as follows: Figure 2 As shown, it includes:

[0032] Step 202: Collect the current temperature of the cooling component of the wearable air conditioner.

[0033] Specifically, when the wearable air conditioner is activated, the temperature sensor 103 collects the current temperature of the cooling component 105. The microcontroller 102 can control the temperature sensor 103 to collect the current temperature of the cooling component 105 of the wearable air conditioner at fixed intervals according to a set frequency. In other embodiments, the microcontroller 102 can control the temperature sensor 103 to continuously collect the current temperature of the cooling component 105 of the wearable air conditioner. It is understood that the temperature sensor 103 of this invention collects the temperature of the cooling component 105 rather than the user's skin temperature, avoiding problems such as difficulty in skin-sensor contact, large individual differences, and high compliance risks.

[0034] In other embodiments, the temperature of the user's skin (such as the neck) at the point where the wearable air conditioner is worn can also be collected.

[0035] Step 204: When the current temperature of the cooling component reaches the first temperature, control the reduction of the operating power of the semiconductor cooler so that the current temperature of the cooling component rises from the first temperature.

[0036] It is understandable that, in practical applications, steps 202 to 204 can occur at any time during actual operation; they can occur when the wearable air conditioner is first started, when it ends, or during operation. No limitation is made here. In practical applications, it is also possible to first control and increase the operating power of the semiconductor cooler 101 to lower the current temperature of the cooling component 105 from the second temperature. Then, when the current temperature of the cooling component 105 drops to the first temperature, the operating power of the semiconductor cooler 101 is controlled to decrease, causing the current temperature of the cooling component 105 to rise from the first temperature.

[0037] It is understood that, in the wearable air conditioner control method provided by the present invention, the order of the steps in the flowchart can be changed according to different needs, and some steps can be omitted.

[0038] exist Figure 2 In this flowchart, steps 202 through 206 can be ordered differently depending on the requirements, and some steps can be omitted. For example, the order of steps 204 and 206 can be interchanged. That is, step 204 can be executed before step 206.

[0039] In one embodiment, the wearable air conditioner provides multiple operating levels, each corresponding to a different target power of the thermoelectric cooler. After the wearable air conditioner is activated, the microcontroller 102 sends a control signal to the power drive circuit 104 according to the target power corresponding to the user-set operating level. The power drive circuit 104 responds to the control signal, driving the thermoelectric cooler to increase its operating power to the target power and operate at the target power.

[0040] The power drive circuit 104 can drive the operating power of the thermoelectric cooler 101 to the target power in two ways: either by gradually increasing the operating power of the thermoelectric cooler 101 to the target power, or by directly adjusting the operating power of the thermoelectric cooler 101 to the target power. No limitation is made here. In this embodiment, the method of gradually increasing the operating power of the thermoelectric cooler 101 driven by the power drive circuit 104 is described.

[0041] like Figure 3 As shown, the solid line represents the temperature change curve of the cooling component 105, and the dashed line represents the power change curve of the thermoelectric cooler 101. After the wearable air conditioner is activated, the microcontroller 102 sends a control signal to the power drive circuit 104 based on the target power corresponding to the operating level. The power drive circuit 104 responds to the control signal, driving the operating power of the thermoelectric cooler 101 to gradually increase until it reaches the target power. In actual operation, affected by factors such as the heat sink and ambient temperature, the operating power of the thermoelectric cooler 101 fluctuates around the target power until it stabilizes. Correspondingly, the temperature of the cooling component 105 decreases as the operating power of the thermoelectric cooler 101 increases until it stabilizes.

[0042] In this embodiment, after the wearable air conditioner is turned on, the temperature of the cooling component 105 decreases continuously as the power of the semiconductor cooler 101 increases, and then drops to the first temperature.

[0043] The first temperature refers to the lowest temperature that the cooling component 105 can reach when the semiconductor cooler 101 is running stably at the target power corresponding to the current setting. It should be understood that the first temperature corresponding to the same operating setting is not the same under different working conditions (human skin temperature, external ambient temperature). For example, when the external ambient temperature is high, the first temperature achievable at the same setting is lower than the first temperature achievable at the same setting when the external ambient temperature is low.

[0044] In one example, when the microcontroller 102 collects the operating power of the thermoelectric cooler 101, the temperature of the cooling conductor 105 corresponding to when the thermoelectric cooler 101 stabilizes at the target power is taken as the first temperature. For example, if the operating power corresponding to the first setting is 10W, when the microcontroller 102 detects that the operating power of the thermoelectric cooler 101 is stable at 10W, it collects the current temperature of the cooling conductor 105 through the temperature sensor 103 as the first temperature.

[0045] In one example, the microcontroller 102 continuously collects the current temperature of the cooling component through the temperature sensor 103. When it is detected that the temperature of the cooling component 105 is stable at the working power corresponding to the current setting, the collected current temperature is determined as the first temperature.

[0046] Specifically, when the wearable air conditioner is running at the current setting, if the current temperature difference of the cooling component 105 is less than the threshold within the first duration, it can be determined that the temperature of the cooling component 105 is stable, and the collected current temperature is determined as the first temperature.

[0047] For example, if the current temperature difference of the cooling component 105 during at least two sampling times within the first duration is less than a threshold, the temperature of the cooling component 105 can be determined to be stable, and the current temperature collected can be identified as the first temperature. The first duration can be a preset duration related to the sampling frequency, such as the duration corresponding to five consecutive sampling times, or the duration corresponding to two consecutive sampling times.

[0048] It is worth noting that the "threshold" refers to a preset, small temperature difference value, which represents the maximum allowable temperature fluctuation range of the coolant 105 during the determination period, when the coolant 105 is determined to have reached stability. The threshold can be set from 0.01°C to 0.5°C. For example, it can be 0.01°C, 0.05°C, 0.08°C, 0.1°C, 0.15°C, 0.2°C, 0.25°C, 0.3°C, 0.35°C, or 0.5°C.

[0049] It is worth noting that the first duration is a preset observation time window, which can be set from 0.5 to 5 seconds. For example, 0.5 seconds, 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds.

[0050] Specifically, the microcontroller 102 can control the temperature sensor 103 to collect the current temperature of the cooling component 105 of the wearable air conditioner, continuously monitor all temperature values ​​(e.g., 5 values) collected within a first duration (e.g., 4 seconds), and calculate the difference between the maximum and minimum values ​​among these temperature values ​​(i.e., the current temperature difference). If the difference is less than a threshold (e.g., 0.2°C), the microcontroller 102 can be certain that the temperature of the cooling component 105 has fluctuated within a very small range, thereby determining that the cooling component 105 is in a "stable" state, and recording the current temperature value as the "first temperature".

[0051] In this way, the optimal cooling performance benchmark value that the wearable air conditioner can achieve under the current environment (such as ambient temperature and human body temperature) and current setting can be automatically and accurately measured, providing a key calibration temperature for subsequent precise control.

[0052] When the current temperature of the cooling component 105 reaches the first temperature, the operating power of the semiconductor cooler 101 is reduced. As the operating power of the semiconductor cooler 101 decreases, the temperature of the cooling component 105 increases accordingly.

[0053] Step 206: When the current temperature of the cooling component rises to the second temperature, control the increase of the operating power of the semiconductor cooler so that the current temperature of the cooling component drops from the second temperature.

[0054] Specifically, when the current temperature of the cooling element 105 rises to the second temperature, the current temperature of the cooling element 105 is reduced from the second temperature by controlling and increasing the operating power of the semiconductor cooler 101.

[0055] In one embodiment, the second temperature is higher than the first temperature, and the target temperature difference between the second and first temperatures is a preset value. The second temperature is determined based on the first temperature and the preset target temperature difference. For example, if the first temperature is 26°C and the target temperature difference is 5°C, the second temperature is 31°C. In this embodiment, the second temperature that triggers the increase in operating power is not a fixed value, but is dynamically calculated based on the first temperature and the target temperature difference. This allows the wearable air conditioner to dynamically determine the second temperature that triggers the increase in operating power based on the current operating conditions, making the temperature variation range of the cooling component 105 relatively fixed.

[0056] The method of this application involves reducing the operating power of the thermoelectric cooler 101 when the temperature of the cooling component 105 drops to a first temperature, causing the temperature of the cooling component 105 to rise from the first temperature. When the temperature of the cooling component 105 rises to a second temperature, the operating power of the thermoelectric cooler 101 is increased, causing the temperature of the cooling component 105 to drop from the second temperature. This causes the temperature of the cooling component 105 to rise from the first temperature to the second temperature and then drop again, reactivating the cold receptors on the skin and allowing the user to continuously feel coolness, overcoming the skin temperature adaptation phenomenon. Simultaneously, because the user can continuously feel coolness at the current setting, the need for the user to adjust the setting to a higher level for the wearable air conditioner is reduced, thus extending the wearable air conditioner's battery life. The method of this application achieves both seemingly contradictory goals: enabling the wearable air conditioner to provide a continuous cooling experience for the user and extending the product's battery life.

[0057] Understandably, in existing wearable air conditioners, even if the thermophysical temperature of the cooling component 105 remains constant, the user's skin's cold receptors will adapt over time, causing the subjectively perceived intensity of the "cold sensation" to gradually weaken until it disappears. This makes it impossible for the constant-temperature cooling mode of existing wearable air conditioners to provide users with a consistently good experience.

[0058] In addition, in pursuit of a strong, immediate cooling sensation, users tend to select the highest cooling setting, causing the semiconductor cooler 101 to operate at high power continuously, resulting in a rapid depletion of battery power and making the device's battery life insufficient to meet the user's daily usage needs.

[0059] Faced with the above-mentioned technical problems, those skilled in the art are likely to follow a conventional "linear" thinking path: that is, if the user does not feel cold, the cooling level is manually or automatically increased, and the lower temperature is maintained with higher power output, which will cause the wearable air conditioner to consume power faster, making the device's battery life unable to meet the user's daily use needs.

[0060] In this application, by raising the temperature of the cooling element 105 from a first temperature to a second temperature and then lowering it again, the cold receptors on the skin are reactivated, thereby actively creating a dynamic, fluctuating temperature field on the user's skin, allowing the user to continuously feel coolness and overcoming the skin temperature adaptation phenomenon. This application's technical solution breaks away from the conventional thinking of those skilled in the art, effectively combining the characteristics of human senses, allowing users to experience a continuous cooling sensation when using a wearable air conditioner. Furthermore, in this invention's technical solution, during the temperature rise phase of the cooling element 105, the semiconductor cooler 101 operates at a power level lower than the current rated maximum power, significantly reducing its average power. Therefore, this application's technical solution effectively solves the two relative technical problems of "insufficient cooling sensation for the user" and "insufficient battery life." The wearable air conditioner control method provided in this application can reduce the energy consumption of the wearable air conditioner while improving its overall cooling effect, effectively extending the battery life of a single charge.

[0061] In one embodiment, such as Figure 4 As shown, a control method for a wearable air conditioner includes:

[0062] Step 402: Collect the current temperature of the cooling component of the wearable air conditioner.

[0063] Step 404: Determine if the current temperature has reached the first temperature. If yes, proceed to step 406.

[0064] Step 406: Control the reduction of the operating power of the semiconductor cooler so that the current temperature of the cooling component rises from the first temperature.

[0065] Step 408: Determine if the current temperature has risen to the second temperature. If so, proceed to step 410.

[0066] Step 410: Control the increase of the operating power of the semiconductor cooler so that the current temperature of the cooling element drops from the second temperature.

[0067] The implementation process and principle of the above steps have been recorded in steps 202 to 206, and will not be repeated here.

[0068] After step 410, return to step 404 and subsequent steps to cyclically adjust the operating power of the thermoelectric cooler according to the current temperature of the cooling element, thereby achieving a cycle in which the current temperature of the cooling element cyclically rises from the first temperature to the second temperature and then falls back to the first temperature.

[0069] It is understandable that, in practical applications, steps 402 to 410 can occur at any time during actual operation; they can occur at the start of the wearable air conditioner's operation, at the end of its operation, or during its operation. No limitation is made here. In practical applications, it can also be determined whether the current temperature of the cooling component 105 has reached a second temperature. If the second temperature is reached, the operating power of the semiconductor cooler 101 is increased to lower the current temperature of the cooling component 105 from the second temperature. Then, it is determined whether the current temperature of the cooling component 105 has reached a first temperature. If the first temperature is reached, the operating power of the semiconductor cooler 101 is decreased to raise the current temperature of the cooling component 105 from the first temperature.

[0070] It is understood that, in the wearable air conditioner control method provided by the present invention, the order of the steps in the flowchart can be changed according to different needs, and some steps can be omitted.

[0071] exist Figure 4 In this flowchart, the order of steps 402 to 410 can be changed according to different needs, and some steps can be omitted. For example, the order of steps 404 and 408 can be interchanged, that is, step 404 can be executed before step 208; the order of steps 406 and 410 can be interchanged, that is, step 406 can be executed before step 410.

[0072] Figure 6 The solid line in the graph represents the temperature change curve of the cooling component 105, and the dashed line represents the power change curve of the semiconductor cooler 101. For example... Figure 5 and Figure 6As shown, the current temperature of the cooling component 105 is monitored in real time. When the current temperature of the cooling component 105 reaches a first temperature, the operating power of the thermoelectric cooler 101 is reduced, and the temperature of the cooling component 105 rises from the first temperature as the operating power of the thermoelectric cooler 101 decreases. When the current temperature of the cooling component 105 rises to a second temperature, the current temperature of the cooling component 105 is reduced from the second temperature by increasing the operating power of the thermoelectric cooler 101. This control is repeated cyclically. Figure 6 As shown, the temperature of the cooling component 105 can be cyclically increased from the first temperature to the second temperature and then decreased back to the first temperature.

[0073] contrast Figure 3 It can be observed that in traditional wearable air conditioner control methods, after the wearable air conditioner is activated, the operating power of the semiconductor cooler 101 gradually increases until it reaches the target power. The temperature of the cooling component 105 decreases and gradually stabilizes as the operating power of the semiconductor cooler 101 increases. Without changing the operating setting, the temperature of the cooling component 105 remains stable at a certain level for an extended period, which can lead to skin temperature adaptation issues.

[0074] Skin temperature adaptation is a pain point for wearable air conditioners. Specifically, when the skin is exposed to a constant low temperature for an extended period, nerve receptors gradually adapt to this temperature, leading to a weakening or even disappearance of the "cooling sensation," even if the actual temperature remains low. Users may feel that "it doesn't feel as cool anymore." When users experience this, they often continuously increase the temperature setting to achieve an even "cooler" feeling, which reduces the battery life of the wearable air conditioner due to operating at higher settings.

[0075] The control method for wearable air conditioning in this application, such as Figure 5 and Figure 6As shown, by collecting the current temperature of the cooling component 105, when the current temperature decreases and stabilizes at a first temperature, the operating power of the semiconductor cooler 101 is reduced to allow the temperature of the cooling component 105 to rise from the first temperature. When the temperature of the cooling component 105 rises to a second temperature, the operating power of the semiconductor cooler 101 is actively increased to allow the temperature of the cooling component 105 to drop from the second temperature, forming a dynamic cycle. By monitoring the real-time temperature of the cooling component 105 of the wearable air conditioner and adjusting the operating power of the semiconductor cooler 101 according to the real-time temperature, the real-time temperature of the cooling component 105 cycles from the first temperature to the second temperature and then back to the first temperature. In this way, the adaptation process of the nervous system is broken by continuously reactivating the cold receptors on the skin. Each time the user re-enters a "cooler" state from a "warmer" state, they will feel a significant coolness again, thus maintaining a continuous cool sensation and overcoming the skin temperature adaptation phenomenon. Under unchanged external environmental conditions, the user can continuously feel coolness at the current setting, reducing the need for the user to turn up the setting to run the wearable air conditioner at a high setting, thereby extending the battery life of the wearable air conditioner. The method in this application can achieve two seemingly contradictory goals: enabling users to continuously feel coolness with wearable air conditioning and extending the product's battery life.

[0076] In one embodiment, the temperature of the cooling element 105 cycles from a first temperature to a second temperature and then back to the first temperature, continuously reactivating the cold receptors on the skin, allowing the user to continuously feel a cooling sensation. The temperature difference between the second and first temperatures is crucial in this process. If the temperature difference is too small, the temperature change of the cooling element 105 is small, resulting in minimal stimulation of the skin's cold receptors, thus failing to achieve the desired effect of continuous cooling for the user. Conversely, if the temperature difference is too large, the temperature change of the cooling element 105 is significant. This can lead to excessively high temperatures, giving the user the illusion that the product is "broken," and can also cause abrupt temperature changes during use. For example, the user may experience sudden shifts between excessively cold and insufficiently cool temperatures. Such strong temperature fluctuations negatively impact the user experience, negating the inherent "seamless" comfort of temperature regulation.

[0077] Therefore, in one embodiment, a temperature difference range of 2~6℃ between the second temperature and the first temperature is more suitable. This temperature adjustment range is sufficient for the receptors to clearly detect the change, effectively breaking the skin's temperature adaptation without causing discomfort to the user.

[0078] In practice, the manufacturer can set the target temperature difference for dynamic adjustment of the wearable air conditioner within this range, for example, a target temperature difference of 4℃. The second temperature is determined based on the first temperature and the preset target temperature difference. For example, if the first temperature is 26℃, the second temperature would be 30℃. The wearable air conditioner lowers the operating power of the semiconductor cooler 101 when the temperature of the cooling component 105 drops to 26℃, causing the temperature of the cooling component 105 to rise. When the temperature of the cooling component 105 rises to 30℃, the operating power of the semiconductor cooler 101 is increased, causing the temperature of the cooling component 105 to drop. Thus, the temperature of the cooling component 105 cycles from 26℃ to 30℃ and then back to 26℃, continuously reactivating the cold receptors on the skin, allowing the user to continuously feel a cooling sensation.

[0079] In some embodiments, the manufacturer may set the temperature difference between the second temperature and the first temperature of the wearable air conditioner to be 2~6℃. During actual operation, the wearable air conditioner dynamically determines the specific target temperature difference between the second temperature and the first temperature based on the external environment and skin temperature.

[0080] Specifically, when the ambient temperature or skin temperature is higher than the preset value, the target temperature difference can be set to the upper limit of the temperature difference range, or close to the upper limit. For example, when the ambient temperature is high, the specific target temperature difference can be set to 4℃, 5℃, or 6℃. This allows for a cooling-warming cycle with higher power, providing strong cooling while breaking temperature adaptation and offering an effective cooling sensation.

[0081] When the ambient temperature or skin temperature is lower than the preset value, the target temperature difference can be set to the lower limit of the temperature difference range, or close to the lower limit. For example, when the ambient temperature is relatively cool, the specific target temperature difference can be set to 2°C or 3°C, which can break the temperature adaptation and provide an effective cooling sensation.

[0082] In this way, the target temperature difference between the second temperature and the first temperature can be dynamically and intelligently determined based on the external ambient temperature or human skin temperature, so as to meet the needs of the actual use environment.

[0083] In actual control, the way to reduce the operating power of the semiconductor cooler 101 is to control the operating power of the semiconductor cooler 101 to be reduced from the first operating power to the second operating power.

[0084] The first operating power refers to the operating power corresponding to when the semiconductor cooler 101 causes the temperature of the cooling component 105 to reach the first temperature, which is usually the target power corresponding to the current operating level.

[0085] The second operating power refers to the operating power required by the semiconductor cooler 101 to bring the temperature of the cooling component 105 to the second temperature. It should be understood that the second operating power is not fixed, but is closely related to the external ambient temperature, human skin temperature, etc.

[0086] The system can determine the second power required to reach the second temperature based on the current external ambient temperature, human skin temperature, the first temperature, and the second temperature, and control the operating power of the thermoelectric cooler 101 to decrease from the first operating power to the second operating power, thereby raising the current temperature of the cooling component 105 from the first temperature to the second temperature. For example, the operating power of the thermoelectric cooler 101 can be directly reduced from 10W to 5W.

[0087] However, this method may cause the temperature of the cooling component 105 to rise rapidly in a short period of time. Users will clearly perceive the rapid increase in the cooling temperature of the wearable air conditioner and may mistakenly believe that the wearable air conditioner has stopped cooling or has been turned off. This is an abrupt and uncomfortable experience, as if reminding users that "the device is saving power," thus disrupting the immersive cooling sensation.

[0088] To address this issue, in one embodiment, controlling the reduction of the operating power of the thermoelectric cooler 101 includes: gradually reducing the operating power of the thermoelectric cooler 101 over time according to a first change function. By gradually reducing the operating power of the thermoelectric cooler 101 over time according to the first change function, the abruptness and abnormal sensation of a sudden temperature rise caused to the user can be reduced.

[0089] In one embodiment, the method of controlling the increase in the operating power of the thermoelectric cooler 101 can be: controlling the operating power of the thermoelectric cooler 101 to increase from a second operating power to a first operating power. By controlling the operating power of the thermoelectric cooler 101 to increase from the second operating power to the first operating power, the current temperature of the cooling conductor 105 is reduced from the second temperature to the first temperature. For example, the operating power of the thermoelectric cooler 101 is controlled to increase from 5W to 10W.

[0090] In one embodiment, if the operating power of the thermoelectric cooler 101 is directly increased from the second operating power corresponding to the second temperature to the first operating power corresponding to the setting, the temperature of the cooling component 105 will drop rapidly in a short period of time, and the user will clearly perceive the rapid drop in the cooling temperature of the wearable air conditioner. Physiologically, skin temperature receptors are very sensitive to the rate of change. The faster the cooling and the more intense the stimulation, the faster and more intense the receptors' adaptation process will start in order to protect themselves. The user will feel "cooling down quickly, but also heating up quickly." After the strong initial cooling sensation, the receptors quickly fatigue, and the user will feel "not cool anymore" even faster, thus creating an urge to increase the setting again. This contradicts the need to reduce the need to increase the setting.

[0091] To address this issue, in one embodiment, controlling the increase in the operating power of the thermoelectric cooler 101 includes: gradually increasing the operating power of the thermoelectric cooler 101 over time according to a second variation function. By gradually increasing the operating power of the thermoelectric cooler 101 over time according to the second variation function, the abruptness and abnormal sensation of a sudden drop in temperature caused to the user can be reduced.

[0092] The first and second change functions can be set to any one of piecewise functions, linear functions, or S-curve functions, depending on the requirements.

[0093] In one embodiment, the first change function is a linear decreasing function, that is, the operating power of the semiconductor cooler 101 decreases uniformly and at a constant rate over time, thereby causing the temperature of the cooling component 105 to rise slowly and uniformly linearly over time.

[0094] Specifically, the expression for the first change function can be:

[0095] ;

[0096] in, Indicates power, This represents the temperature variation factor, which is the slope affecting the linear change in power. It is a constant. For time.

[0097] Specifically, in generating the first change function Then, the constant can be determined by substituting the numerical values. The value of .

[0098] Specifically, it can be Figure 6 Substituting the points of the power change curve of the semiconductor cooler 101 into the first change function, the constant is calculated. The value of the constant can be calculated by substituting the working power corresponding to time "t0" and "t0" into the first change function. The value of .

[0099] In one embodiment, the second change function is a linearly decreasing function, that is, the operating power of the semiconductor cooler 101 increases uniformly and at a constant rate over time, thereby causing the temperature of the cooling component 105 to decrease slowly and uniformly linearly over time.

[0100] Specifically, the expression for the second change function can be:

[0101] ;

[0102] in, Indicates power, This represents the temperature variation factor, which is the slope affecting the linear change in power. It is a constant. For time.

[0103] By controlling the operating power of the thermoelectric cooler 101 to decrease uniformly and at a constant rate over time when the temperature of the cooling component 105 drops to a first temperature, and then controlling the operating power of the thermoelectric cooler 101 to increase uniformly and at a constant rate over time when the temperature of the cooling component 105 rises to a second temperature, the temperature of the cooling component 105 is cyclically and uniformly raised from the first temperature to the second temperature and then lowered back to the first temperature at a constant rate. This continuously reactivates the cold receptors on the skin, allowing the user to feel a continuous cooling sensation without realizing it.

[0104] This slow change simulates a very natural process of ambient temperature change, rather than a sudden malfunction of the device. This gentle stimulation is sufficient to prevent sensory adaptation (because the temperature is changing), but its slowness does not arouse the user's alarm or discomfort, "tricking" the user's nervous system to maintain the feeling of "continuous coolness".

[0105] At the same time, this linear power regulation is beneficial to both the circuitry and the system of wearable air conditioners.

[0106] In terms of circuitry, a sudden drop in power could cause a momentary reverse voltage or current surge across the semiconductor cooler 101, which would negatively impact the long-term lifespan of both the cooler 101 and the drive circuit. Rapid temperature changes could also cause stress in the cooling conductor 105 or surrounding structures due to thermal expansion and contraction. In terms of system control, such large step changes can easily lead to system overshoot or oscillation, requiring more complex control algorithms for stabilization.

[0107] The linear power regulation in this application allows for a smooth power decrease, which is very friendly to the semiconductor cooler 101 and the circuitry, representing a "soft" control. The temperature field changes of the entire system are also smooth, easy to predict and manage, and the system stability is extremely high.

[0108] Specifically, the slope of the second change function Then, the constant can be determined by substituting the numerical values. The value of .

[0109] Specifically, it can be Figure 6 Substituting the points of the power change curve of the semiconductor cooler 101 into the second change function, the constant is calculated. The value of the constant can be calculated by substituting the time "t1" and the corresponding working power into the second variation function. The value of .

[0110] In one embodiment, the rate of linear adjustment is related to the slopes of the first and second change functions. The larger the slope, the greater the rate of temperature adjustment; the smaller the slope, the smaller the rate of temperature adjustment.

[0111] In one embodiment, the slopes of the first change function and the second change function are preset values ​​or random values ​​within a preset slope range.

[0112] Manufacturers can pre-set a slope range based on the temperature difference range and the expected adjustment time or effect. The slopes of the first and second change functions can be random values ​​within this slope range. This results in slightly different rhythms and speeds of warming / cooling for different devices, or even the same device, each time it is used. This prevents the skin's temperature receptors from forming a stable adaptation expectation, thus maintaining the freshness of the cooling sensation for a longer period and more effectively breaking the adaptation cycle.

[0113] Manufacturers can preset a slope value based on the temperature difference range and the expected adjustment time or effect, thereby maintaining the desired cooling sensation.

[0114] In one embodiment, when the wearable air conditioner first reduces the operating power of the semiconductor cooler 101 while operating at its current setting, the slope of the first change function is a preset value or a random value within a preset slope range. The slope of the change function for the next adjustment is determined based on the slope of the temperature change function generated by the previous adjustment.

[0115] Specifically, after the wearable air conditioner is turned on or changes gears, when the current temperature of the cooling component 105 decreases and stabilizes at the first temperature, it controls the reduction of the operating power of the semiconductor cooler 101 by using a random value or a preset value as the slope of the first change function, so that the temperature of the cooling component 105 rises to the second temperature.

[0116] In actual operation, influenced by user skin temperature and external ambient temperature, the adjustment time to reach the second temperature varies even with the same slope of the function. Human temperature receptors adapt very quickly to regular, predictable stimuli. If the operating power of the semiconductor cooler 101 is always controlled linearly with the same slope, it will lead to poor cooling effect and inadequate comfort of the cooling sensation.

[0117] In this embodiment, the slope of the temperature change curve generated by the current power adjustment is used to dynamically determine the slope of the first or second change function to be used in the next power adjustment. Thus, the actual result (true slope) of the current control process can be used as feedback to optimize the slope used in the next control.

[0118] Specifically, after controlling the reduction of the operating power of the semiconductor cooler 101 or controlling the increase of the operating power of the semiconductor cooler 101, the method of this application further includes: determining the slope of the temperature change curve of the current adjustment based on the first temperature, the second temperature, the start time and the end time of the current power adjustment; and modifying the slope of the first change function or the second change function used in the next power adjustment based on the slope of the temperature change curve of the current adjustment.

[0119] Specifically, based on the first temperature, the second temperature, the start time, and the end time of the current power adjustment, a temperature change curve formula can be fitted:

[0120] ;

[0121] in, Here, is the temperature variation factor of the cooling component, is the slope of the temperature change curve, and t is time. It is a constant.

[0122] The slope of the temperature change curve can be used as a reference. The slope of the first or second change function is assigned to the next power regulation of the semiconductor cooler 101.

[0123] In this embodiment, the slope of the temperature change curve obtained after the current power adjustment of the semiconductor cooler 101 is corrected according to the slope of the first change function or the second change function used for the next power adjustment. This makes the change trend of the power adjustment of the semiconductor cooler 101 the same as or compatible with the change trend of the temperature change of the cooling component 105, thereby allowing the user to get the best cooling experience.

[0124] It is understandable that the temperature change trend of the cooling component 105 is related not only to its own properties but also to its environment. The temperature change trend of the cooling component 105 will also be different in different environments.

[0125] For example, if the fitted temperature change rate is slow, it indicates that the current environment has high thermal inertia and / or the temperature of the cooling component 105 changes slowly. Therefore, the trend of the power change function (first change function and second change function) should be reduced accordingly, allowing the power to change in a more gradual manner. This avoids overshooting or undershooting due to excessively rapid power changes, ensuring a smoother temperature control process and achieving more precise temperature control. Conversely, if the temperature change rate is fast, it indicates that the current environment has low thermal inertia and / or the temperature of the cooling component 105 changes rapidly. Therefore, the slope of the power change function (first change function and second change function) should be increased accordingly, allowing the power to change more quickly, thereby improving the response speed and ensuring that the target temperature can be reached quickly.

[0126] Therefore, by setting the power regulation trend of the semiconductor cooler 101 to be the same as or compatible with the temperature change trend of the cooling component 105, the user experience is improved. This results in a continuous, natural, and uninterrupted temperature fluctuation perceived by the user's skin, rather than an uncontrolled state of sudden hot and cold changes.

[0127] In addition, it can enable the semiconductor cooler to adjust its power at a rate that conforms to the current operating conditions within the temperature range specified by the cooling element 105.

[0128] In one embodiment, the control method for a wearable air conditioner is as follows: Figure 7 As shown, it includes: step 702, in response to a power-on command or a gear adjustment command, starting the wearable air conditioner to operate at the current gear.

[0129] Step 704: Collect the current temperature of the cooling component of the wearable air conditioner.

[0130] Step 706: When the current temperature difference of the cooling component is less than the threshold within the first time period, the collected current temperature is determined as the first temperature.

[0131] Step 708: When the current temperature of the cooling component drops to the first temperature, the operating power of the semiconductor cooler is gradually reduced over time according to the first change function, so that the current temperature of the cooling component rises from the first temperature.

[0132] When the operating power of the semiconductor cooler 101 is reduced for the first time, the slope of the first change function is a preset value or a random value within the preset slope range.

[0133] Step 710: Determine the slope of the temperature change curve for the current adjustment based on the first temperature, the second temperature, the start time and the end time of the current power adjustment; modify the slope of the second change function used in the next power adjustment based on the slope of the temperature change curve for the current adjustment.

[0134] Step 712: When the current temperature of the cooling component rises to the second temperature, the operating power of the semiconductor cooler is gradually increased over time according to the second change function, so that the current temperature of the cooling component decreases from the second temperature.

[0135] Step 714: Determine the slope of the temperature change curve for the current adjustment based on the first temperature, the second temperature, the start time and the end time of the current power adjustment; modify the slope of the first change function used in the next power adjustment based on the slope of the temperature change curve for the current adjustment.

[0136] If the operation does not end after step 714, it returns to step 708, causing the temperature of the cooling component 105 to cycle from the first temperature to the second temperature and then back to the first temperature. This continuously reactivates the cold receptors on the skin, allowing the user to continuously feel coolness and overcome the skin temperature adaptation phenomenon. Simultaneously, because the user can continuously feel coolness at the current setting, the need for the user to adjust to a higher setting to run the wearable air conditioner at a higher speed is reduced, thus extending the wearable air conditioner's battery life.

[0137] It is understandable that, in practical applications, steps 702 to 714 can occur at any time during actual operation; they can occur at the start of the wearable air conditioner's operation, at the end of its operation, or during its operation. No limitation is made here. In practical applications, it can also be determined whether the current temperature of the cooling component 105 has reached a second temperature. If the second temperature is reached, the operating power of the semiconductor cooler 101 is increased to lower the current temperature of the cooling component 105 from the second temperature. Then, it is determined whether the current temperature of the cooling component 105 has reached a first temperature. If the first temperature is reached, the operating power of the semiconductor cooler 101 is decreased to raise the current temperature of the cooling component 105 from the first temperature.
