[0015] Furthermore, the insulation layer is made of a flexible material and is fixedly connected to the outer shell at one end, while the other end is detachably connected to the outer surface of the insulation layer.

[0016] A method for controlling a personal temperature regulator, applied to the personal temperature regulator, includes the following steps:

[0017] The control module acquires the switch signal;

It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of protection of the invention.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0047] The bulkiness of air conditioners has always been a major drawback, making them unsuitable for hot environments. However, with the rapid advancements in semiconductor materials, lightweight and portable designs have become increasingly popular. Therefore, to meet the needs of modern life, we have combined the latest semiconductor refrigeration technology with a sophisticated design to improve upon the previously bulky air conditioner, making it lightweight, convenient, and easy to use, thus filling the gap in the portable air conditioning market. This will make life in hot environments more convenient and comfortable.

[0048] Thermoelectric refrigeration utilizes materials with thermoelectric energy conversion properties, exhibiting cooling capabilities when direct current is applied. Because semiconductor materials possess optimal thermoelectric energy conversion performance, thermoelectric refrigeration is also known as semiconductor refrigeration. Semiconductor refrigeration is a new refrigeration technology based on five thermoelectric effects: the Seebeck effect, the Peltier effect, the Thomson effect, the Joule effect, and the Fourier effect. Among these, the Seebeck, Peltier, and Thomson effects demonstrate that the interconversion of electrical and thermal energy is direct and reversible, while the other two are irreversible thermal effects.

[0049] like Figure 2 As shown, thermocouples are composed of semiconductor materials. A thermocouple has two arms, one made of P-type semiconductor and the other of N-type semiconductor. Both ends of the thermocouple arms have busbars, also known as laminated busbars, which are multi-layered power module electrical connection components that can connect to the power distribution points of multiple circuits. A pair of thermocouples composed of N-type and P-type materials will experience heat absorption and release at the thermocouple junction due to the different directions of the current flow; this phenomenon is called the Peltier effect. The upper end absorbs heat from the outside, while the lower end releases heat to the outside. Multiple such thermocouples can be used to create a thermoelectric cooling stack. After being powered on, various heat transfer devices continuously dissipate heat from the hot end, thus maintaining a certain temperature. When the thermoelectric stack is connected to a device, the cold end absorbs heat and cools down, thereby achieving the purpose of cooling the working environment.

[0050] P-type semiconductors, also known as hole-type semiconductors, are impurity semiconductors where the hole concentration is much greater than the free electron concentration, and their conductivity mainly relies on holes in the valence band. N-type semiconductors, also known as electron-type semiconductors, are impurity semiconductors where the free electron concentration is much greater than the hole concentration, and their conductivity is mainly based on electrons. Therefore, from a microscopic perspective, when a DC power supply is applied, the current direction at the cold junction is from n to p. Holes in the P-type semiconductor move away from the cold junction, and electrons at the junction become free electrons. This electron movement leaves holes in the P-type semiconductor, forming electron-hole pairs. These free electrons enter the N-type semiconductor and release energy at the junction. However, this released energy is far less than the energy absorbed by the electron-hole pairs. A similar situation occurs in the P-type semiconductor. Therefore, the junction becomes the cold junction, achieving a cooling effect through heat absorption.

[0051] By changing the polarity of the current passing through the thermoelectric cooler, the cooling and heating ends of the thermoelectric cooler can be altered. Through research, the applicant found that existing portable air conditioning devices based on thermoelectric coolers lack insulation layers, resulting in extremely rapid heat convection and low energy efficiency. Therefore, the applicant believes it is necessary to develop a personal temperature regulator to improve its energy efficiency.

[0052] like Figure 1 As shown, a personal temperature regulator according to one embodiment of the present invention includes a housing, a control module 1, a battery 2, a boost / buck voltage regulation circuit 3, a switching circuit 4, and a thermoelectric cooler 5. The battery 2 is electrically connected to the control module 1, the switching circuit 4 is electrically connected to the battery 2 through the boost / buck voltage regulation circuit 3, and the thermoelectric cooler 5 is electrically connected to the switching circuit 4. The control module 1 is used to acquire a switch signal and control the switching circuit 4 to switch states according to the switch signal, so as to drive the thermoelectric cooler 5 to cool or heat according to the switch signal. The housing is provided with a heat exchange area 14 for contact with human skin, and the personal temperature regulator also includes a heat insulation layer.

[0053] The insulation layer is configured to at least cover the heat exchange area and the corresponding human skin.

[0054] Specifically, the control module 1, battery 2, boost / buck voltage regulation circuit 3, switching circuit 4, and semiconductor cooling chip 5 are installed in the housing. A toggle switch is provided on the side wall of the housing, and the personal temperature regulator generates a switching signal through the toggle switch.

[0055] The switching signals include cooling signals and heating signals. The control module 1 drives the semiconductor cooling chip 5 to perform cooling operation according to the cooling signal and drives the semiconductor cooling chip 5 to perform heating operation according to the heating signal.

[0056] The insulation layer is made of a flexible material and is fixedly connected to the outer shell at one end, while the other end is detachably connected to the outer surface of the insulation layer.

[0057] The insulation layer can be configured as a hook and loop fastener, so that the other end of the insulation layer can pass over the outer shell and be fixedly connected to the outer surface of the insulation layer.

[0058] Alternatively, multiple equally spaced clips can be installed on the outer surface of the insulation layer along its length, and the other end of the insulation layer can be fitted with a clip that matches the clip. By snapping the clip onto the clip, the other end of the insulation layer can be detachably connected to the outer surface of the insulation layer.

[0059] Preferably, the personal temperature regulator further includes an LED11 electrically connected to the control module 1. When the personal temperature regulator is in heating mode, the control module 1 drives the LED11 to work and display red; when the personal temperature regulator is in cooling mode, the control module 1 drives the LED11 to work and display blue.

[0060] Preferably, the personal temperature regulator further includes a fan 6 and two tactile switches 7, and the control module 1 is electrically connected to the fan 6 through a boost circuit 12.

[0061] Two tactile switches 7 are electrically connected to the control module 1 and are used to control the gear position. Generally, one tactile switch 7 is in the "+" position, and the other tactile switch 7 is in the "-" position. The control module 1 controls the voltage of the thermoelectric cooler 5 for cooling or heating and the airflow of the fan 6 based on the signals from the two tactile switches 7.

[0062] The battery 2 is equipped with UVP (UNDER VOLTAGE PROTECTION) and OVP (OVERVOLTAGE PROTECTION) circuits.

[0063] The personal temperature regulator controls the switching circuit 4 via the control module 1 to switch circuits, changing the current flow through the semiconductor cooling chip 5, thus enabling the semiconductor cooling chip 5 to perform cooling or heating operations. A heat exchange area for contact with human skin is provided on the outer casing, allowing users to easily perform cooling or heating operations through this heat exchange area.

[0064] By covering the heat exchange area and the corresponding human skin with the insulation layer, heat transfer can be reduced, energy loss can be decreased, and the insulation and energy-saving efficiency can be improved.

[0065] In other words, the personal temperature regulator solves the problem of severe energy loss during cooling or heating in the prior art due to the lack of insulation material by setting an insulation layer that at least covers the heat exchange area and the corresponding human skin. It can reduce heat transfer, reduce energy loss, and improve insulation and energy-saving efficiency.

[0066] In one embodiment, the personal temperature regulator further includes a USB interface 8 and an overvoltage protection circuit 9, wherein the USB interface 8 is electrically connected to the battery 2 through the overvoltage protection circuit 9.

[0067] The personal temperature regulator also includes a temperature sensor 10.

[0068] The temperature sensor 10 is used to detect the temperature signal of the heat exchange zone and feed it back to the control module 1; wherein, the control module 1 is also used to monitor the power of the battery 2 and monitor the real-time temperature value of the heat exchange zone according to the temperature signal.

[0069] Specifically, the temperature sensor 10 is an NTC thermistor.

[0070] The control module 1 monitors the real-time temperature of the heat exchange zone using the temperature sensor 10 and adjusts the airflow of the fan 6 according to the real-time temperature value.

[0071] In one embodiment, such as Figure 4 As shown, the personal temperature regulator also includes a heat-conducting plate 13, and the heat exchange zone is connected to one end of the semiconductor cooling chip via the heat-conducting plate. A temperature sensor is mounted on the heat-conducting plate to detect the temperature signal of the heat exchange zone and feed it back to the control module.

[0072] By incorporating the heat-conducting sheet, the heat transfer efficiency between the semiconductor cooling chip and the heat exchange zone can be improved.

[0073] In one embodiment, such as Figure 4 as well as Figure 5 As shown, the control module includes a temperature control model. Wherein, Q = cold / heat flow rate, kcal / s; R = thermal resistance between the heat-conducting plate and the cooling plate, °C-s / kcal; Rb = thermal resistance between the heat-conducting plate and the body, °C-s / kcal; Rntc = thermal resistance between the heat-conducting plate and the temperature sensor, °C-s / kcal; Cb = thermal capacitance between the heat-conducting plate and the body, kcal / °C; Cntc = thermal capacitance between the heat-conducting plate and the sensor, kcal / °C; T1 = temperature between the contact surfaces of the heat-conducting plate and the cooling plate; T2 = temperature between the contact surfaces of the heat-conducting plate and the body; T3 = temperature between the contact surfaces of the heat-conducting plate and the sensor.

[0074] In the temperature control model, the rate of temperature change is proportional to the rate of change of heat input; because Q o =T / R, therefore we have the following formula:

[0075]

[0076]

[0077]

[0078]

[0079] Let L{T}=T(s), L{dT / dt}=sT(s), L{q1}=Q i Taking the Laplace transform of the equation, we get RCsT(s) + T(s) = RQ i (s), θ[sRC+1]=RQ i .

[0080] Therefore, the transfer function required for the temperature control model is:

[0081] Preferably, the personal temperature controller further includes an input module for acquiring the cooling and heating temperature values ​​input by the user. This input module includes, but is not limited to, a touchscreen or matrix keypad electrically connected to the control module.

[0082] By setting the transfer function, the control module can adjust the temperature of the heat exchange zone according to the user's settings, thereby improving the accuracy of the personal temperature regulator's temperature control.

[0083] The specific workflow of the personal temperature regulator is as follows:

[0084] 1. After passing through the fuse and overvoltage protection circuit 9, the USB-C interface charges the built-in battery 2 and supplies power to the control module 1; at the same time, it boosts and stabilizes the voltage of the step-up and step-down regulating circuit 3 to supply power to the LED 11 and display the power level (white). When the battery 2 is fully charged, the temperature regulator enters sleep mode.

[0085] 2. Turning the toggle switch up activates the heating mode (LED11 displays red), providing warmth in winter. Upon detecting the switch signal, control module 1 controls switching circuit 4, allowing battery 2 to power the semiconductor cooling chips 5 via boost / buck regulation circuit 3. Temperature feedback from the NTC controller then stabilizes the temperature. Simultaneously, control module 1 monitors the battery 2's charge level and the temperature of the heating element in real time.

[0086] 3. Turning the toggle switch down activates the cooling mode (LED11 displays blue), providing a refreshing feel in summer. Upon detecting the switch signal, control module 1 controls switching circuit 4, allowing battery 2 to power the semiconductor chip via boost / buck regulation circuit 3. Temperature feedback from the NTC controller then stabilizes the temperature. Simultaneously, battery 2 powers fan 6 via boost circuit 12, while the battery level and temperature of the regulator are monitored in real time.

[0087] 4. The two tactile switches 7 control the gear position. The principle is that the upper button is the + gear and the lower button is the - gear. When the control module 1 receives the corresponding signal, it controls the voltage for cooling or heating the semiconductor chip and the airflow of the fan 6.

[0088] 5. The standby current of the temperature regulator is less than 10uA when it is powered off or in sleep mode, so users do not have to worry about the battery being over-discharged and affecting the use of the temperature regulator.

[0089] like Figure 3 As shown, a personal temperature regulator control method, applied to the personal temperature regulator, includes the following steps:

[0090] S1, control module 1 acquires the switch signal.

[0091] S2, the control module 1 controls the switching circuit 4 to switch states according to the switch signal, so as to drive the semiconductor cooling chip 5 to cool or heat according to the switch signal.

[0092] The personal temperature regulator includes an insulation layer, which is configured to at least cover the heat exchange zone and the corresponding human skin.

[0093] The personal temperature regulator control method, by setting up an insulation layer that at least covers the heat exchange area and the corresponding human skin, solves the problem of severe energy loss during cooling or heating in the prior art due to the lack of insulation material. It can reduce heat transfer, reduce energy loss, and improve insulation and energy-saving efficiency.

[0094] In one embodiment, the personal temperature regulator control method further includes the following steps:

[0095] S3, the temperature signal of the heat exchange zone is detected by the temperature sensor 10 and fed back to the control module 1.

[0096] S4, the control module 1 monitors the power level of the battery 2.

[0097] S5, the control module 1 monitors the real-time temperature value of the heat exchange zone according to the temperature signal.

[0098] By monitoring the real-time temperature of the heat exchange zone, the operating voltage of the thermoelectric cooler 5 can be controlled, so that the cooling or heating temperature of the thermoelectric cooler 5 matches the set value.

[0099] In one embodiment, the personal temperature regulator control method further includes the following steps:

[0100] Obtain the control parameters of the personal temperature controllers of multiple users in the area;

[0101] Obtain the real-time time point and real-time average weather temperature of the area where the target personal thermostat is located;

[0102] Obtain control parameters corresponding to real-time and historical time points, as well as real-time average weather temperature and historical average weather temperature.

[0103] Set the initial cooling temperature and initial heating temperature of the target personal temperature controller according to the control parameters;

[0104] The control parameters include an initial cooling temperature value, an initial heating temperature value, historical time points and historical average weather temperatures corresponding to the initial cooling temperature value, and historical time points and historical average weather temperatures corresponding to the initial heating temperature value.

[0105] Specifically, the time point refers to a certain period of time in a day, while the average weather temperature is the average weather temperature corresponding to that period.

[0106] Preferably, the personal temperature regulator further includes a temperature detection module mounted on the surface of the outer casing, which can be a temperature sensor 10. The control module 1 acquires multiple real-time temperature values ​​for a certain period of time at a certain frequency through the temperature detection module, and calculates the average value of the multiple real-time temperature values, using the average value as the average weather temperature.

[0107] The specific method for obtaining the control parameters corresponding to real-time time nodes, historical time nodes, real-time average weather temperature, and historical average weather temperature is as follows: obtain the control parameters of multiple users' personal temperature regulators whose real-time time node and historical time nodes of multiple users' personal temperature regulators in the same area are at the same time node, and whose real-time average weather temperature of the target personal temperature regulator and historical average weather temperature of multiple users' personal temperature regulators in the same temperature range are within the same temperature range.

[0108] Here, the control module 1 has multiple temperature ranges. Setting these temperature ranges allows for better differentiation between specific cooling or heating modes, and enables the setting of the initial cooling and heating temperatures of the target personal thermostat based on the actual weather temperature. This makes the set initial cooling and heating temperatures of the target personal thermostat more accurate and in line with actual needs, meeting the specific requirements of the user.

[0109] In other words, the initial cooling and initial heating temperatures of the target personal temperature controller are set based on the fact that the real-time time point of the target personal temperature controller is the same as the historical time point of multiple users' personal temperature controllers in the same area, and the initial cooling and initial heating temperatures of multiple users' personal temperature controllers in the same temperature range as the real-time average weather temperature of the target personal temperature controller are the same as the historical average weather temperature of multiple users' personal temperature controllers in the same area.

[0110] In one embodiment, the personal temperature regulation control method further includes the following steps:

[0111] Obtain the user's temperature adjustment command;

[0112] According to the temperature adjustment command, calibrate the initial cooling temperature value and the initial heating temperature value of the target personal temperature regulator.

[0113] The temperature adjustment commands include heating initial temperature adjustment commands and cooling initial temperature adjustment commands.

[0114] The control module 1 acquires the temperature adjustment command input by the user, and calibrates the initial cooling temperature value and initial heating temperature value of the target personal temperature regulator according to the temperature adjustment command. This allows the initial cooling temperature value and initial heating temperature value of the personal temperature regulator to meet the user's actual needs, improving its intelligence and user-friendliness.

[0115] In one embodiment, a computer-readable storage medium stores a computer program that, when executed by a processor, implements the personal temperature regulator control method.

[0116] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0117] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
