[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0023] Example 1

[0024] Reference Figure 1 , which is the first embodiment of the present invention, provides a heatstroke prevention work suit, including a work suit body 100 and a refrigeration component 200. The work suit body 100 is blended by natural fibers (such as cotton and linen) and synthetic fibers (such as nylon and polyester fibers), and the refrigeration component 200 is arranged on the side of the work suit body 100 that fits the back of the human body.

[0025] Furthermore, the refrigeration assembly 200 includes a primary refrigeration unit 201 using fan refrigeration, and a secondary refrigeration unit 202 using semiconductor refrigeration.

[0026] Preferably, the primary refrigeration unit 201 includes a heat dissipation fan 201a and an atomizer 201b, and the opening and closing of the two are independently controlled, wherein the heat dissipation fan 201a can adjust the air volume in multiple gears, and the wearer can adjust the air volume of the heat dissipation fan 201a according to his or her own wearing feeling. The output end of the atomizer 201b is toward the front end of the fan blade of the heat dissipation fan 201a. Such an arrangement allows the water vapor sprayed from the output end of the atomizer 201b to be blown toward the human skin through the heat dissipation fan 201a. The blowing of the heat dissipation fan 201a accelerates the diffusion time of the water vapor and increases the diffusion range of the water vapor, that is, reduces the time for the water vapor to absorb heat in the air, thereby improving the effect of the primary refrigeration unit 201 on heat protection and cooling of workers.

[0027] Specifically, at least four groups of primary refrigeration units 201 are provided, and the four groups of primary refrigeration units 201 are respectively provided on the work clothes body 100 corresponding to both sides of the human shoulders and both sides of the human waist. Among them, the two primary refrigeration units 201 provided on the shoulders blow on the human head through the heat dissipation fan 201a, so as to reduce the temperature of the wearer's head and keep the wearer clear-headed. The two primary refrigeration units 201 provided on the waist blow on both sides of the human waist through the heat dissipation fan 201a. The waist is a part of the human body that is prone to heat. By blowing on the waist, the wearer's body temperature can be quickly reduced, effectively preventing the risk of heat stroke and at the same time preventing the water vapor sprayed from the atomizer 201b from falling on the wearer's abdomen, causing the wearer to catch a cold.

[0028] Preferably, the secondary refrigeration unit 202 includes a semiconductor refrigeration sheet 202a, and an MCU 202b for adjusting the temperature of the semiconductor refrigeration sheet 202a; the semiconductor refrigeration sheet 202a utilizes the Peltier effect, that is, when two different conductor materials are connected into an electric couple and a direct current is passed through, heat transfer occurs at the connection point, making one end a cold end and the other end a hot end, wherein the cold end of the semiconductor refrigeration sheet 202a is the side close to the skin of the wearer; and by controlling the size and direction of the current, the cooling effect of the semiconductor refrigeration sheet 202a is adjusted, thereby realizing the cooling function of the work clothes.

[0029] Specifically, there are at least six semiconductor cooling sheets 202a, which are arranged at the parts of the human body that are prone to heat, that is, the six semiconductor cooling sheets 202a are arranged at the work clothes body 100 corresponding to the sides of the armpits, the sides of the middle spine, and the sides below the shoulders.

[0030] As a further improvement, the work clothes also include a power supply component, which uses a lithium battery as a power source, and the power supply component is electrically connected to the electrical components in the refrigeration component 200 to supply power to the electrical components in the refrigeration component 200.

[0031] Example 2

[0032] Reference Figure 1 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the refrigeration component 200 also includes a hose, which is arranged on the side of the work clothes body 100 that fits the human body and passes through the semiconductor refrigeration sheet 202a; both ends of the hose are connected to the water storage chamber of the atomizer 201b, so as to form a closed circulation water circuit. A micro pump is installed on the hose. Due to the extraction of liquid in the water storage chamber of the atomizer 201b, before wearing, the hose and the water storage chamber of the atomizer 201b are filled with water. After wearing, the micro pump is started to make the liquid circulate between the hose and the water storage chamber of the atomizer 201b. When the liquid flows through the wearer's skin, it takes away the heat of the wearer's body. When the liquid flows through the semiconductor refrigeration sheet 202a, it exchanges heat and cools.

[0033] The remaining structures are the same as those of Example 1.

[0034] Example 3

[0035] Reference Figure 2 , which is the third embodiment of the present invention, provides a constant temperature control system, which is applied to the MCU microcontroller 202b described in Example 1, and includes a temperature acquisition module 301, a reading and analysis module 302, an algorithm processing module 303, and an output control module 304.

[0036] Specifically, the temperature acquisition module 301 includes at least one temperature sensor for real-time acquisition of the ambient temperature of the work clothes, and an analog-to-digital converter for converting the acquired temperature signal into a digital model and transmitting it to the MCU 202b.

[0037] Furthermore, the reading and analysis module 302 at least includes a memory arranged in the MCU 202b, which can read the set target temperature value, and the reading and analysis module 302 can compare the target temperature value with the collected current ambient temperature value through the onboard calculation program to obtain the temperature difference.

[0038] Furthermore, the algorithm processing module 303 adopts PID algorithm processing to obtain the output value by multiplying the temperature difference by the corresponding coefficient; specifically, the proportional term output is obtained by multiplying the temperature difference by the proportional coefficient Kp; the integral term output is obtained by accumulating the temperature differences of all times and multiplying by the integral coefficient Ki; the differential term output is obtained by multiplying the difference between the current temperature difference and the previous temperature difference by the differential coefficient Kd.

[0039] Furthermore, the output control module 304 uses PWM (pulse modulation), DAC (digital converter), or other control methods to adjust the power of the semiconductor cooling plate 202a according to the PID output value.
