Self-adaptive fitting multifunctional physiotherapy eye mask and control method thereof Technical Field The invention relates to the technical field of eye protection instruments, in particular to a self-adaptive fitting multifunctional physiotherapy eye shield and a control method thereof. Background With the promotion of public health consciousness, physiotherapy eyeshields with cold compress, hot compress, electric pulse stimulation and other functions are increasingly popular, and are used for relieving eye fatigue, improving blood circulation and assisting treatment related discomfort. The physiotherapy eyeshade on the market mainly has the following limitations that firstly, in the physical structure, most products adopt contact surfaces with fixed shapes, and the facial contour difference of different users cannot be self-adapted, so that insufficient or uneven contact with skin is caused. The utility model has the advantages of not only affecting the wearing comfort and stability, but also causing uneven temperature distribution or current density in the treatment area and seriously affecting the uniformity of physiotherapy effect. Although some products try to use flexible materials, the flexible materials still belong to passive fitting in nature, and active and accurate personalized adaptation is difficult to realize. Secondly, in function control, all functional modules of the existing product are often mutually independent and lack cooperation. For example, the cold compress module and the electrical stimulation module usually rely on the user to manually switch or execute a simple timing program, and the working mode of the cold compress module and the electrical stimulation module is preset and fixed and cannot be dynamically adjusted according to the real-time physiological state of the user. This makes the treatment process less intelligent and targeted, and it is difficult to achieve optimal physiotherapy effect. In addition, the wearing detection mechanism of the existing eyeshade is single or missing, and the wearing state cannot be automatically identified to start and stop the treatment program intelligently, so that the convenience and safety of use are affected. Meanwhile, there are also few products capable of constructing a closed-loop intelligent control system integrating physical signal sensing, physiological state decision and treatment action execution, so that the span from physical fitting to physiological adaptation cannot be realized. Therefore, there is an urgent need in the art for a novel eye mask capable of actively adapting to the facial contour and performing intelligent cooperative therapy based on real-time physiological signals, so as to solve the shortcomings of the prior art in the aspects of personalized adaptation, accurate therapy and intelligent control. Disclosure of Invention Aiming at the defects, the invention provides the self-adaptive fitting multifunctional physiotherapy eyeshade and the control method thereof, and the lasting optimization of physical contact, the physiological adaptation of treatment parameters and the cooperative enhancement of stimulation modes are realized through multi-module linkage, so that the accurate and safe physiotherapy effect is achieved. In order to achieve the purpose, the invention provides the following technical scheme that the self-adaptive fitting multifunctional physiotherapy eyeshade comprises an eyeshade body and a binding belt for fixing the eyeshade body on the head, wherein the eyeshade body is internally integrated with: The cold compress stimulation module comprises at least one flexible cooling patch made of flexible materials, a refrigerating device for refrigerating cooling liquid, a cooling liquid pump and a liquid storage tank, wherein a deformable cavity is arranged in the flexible cooling patch and filled with the cooling liquid, and the cooling liquid pump is used for driving the cooling liquid to circulate in a loop formed by the flexible cooling patch, the refrigerating device and the liquid storage tank; the electric stimulation module is attached to one side of the flexible cooling patch facing the skin and is used for conducting electric pulses to nerves in the skin or collecting signals of load detection; The pressurizing module is used for pressing or extruding the cooling liquid in the liquid storage tank into the accommodating cavity; the sensor module comprises a photoelectric sensor for acquiring heart rate data of a user, a pressure sensor for detecting contact pressure between the flexible cooling patch and skin, and a temperature sensor for detecting temperature of cooling liquid; the control module is respectively and electrically connected with the refrigerating device, the cooling liquid pump, the pressurizing module, the pressure sensor and the photoelectric sensor and is configured to adjust the volume of cooling liquid in the accommodating cavity of the flexible cooling patch by
