The foregoing and other technical matters, features and effects of the present invention will be apparent from the following detailed description of the embodiments with reference to the accompanying drawings of fig. 1 to 13, wherein the structural matters in the embodiments are described below with reference to the accompanying drawings.

Embodiment 1, this embodiment provides a clean protective clothing, refer to fig. 1, including protective clothing and protective clothing integrative being provided with headgear 1, because the improvement point of this scheme mainly involves headgear 1, so other parts of protective clothing are no longer shown in this scheme, its characterized in that, protective clothing wears waistband 2, we are provided with waistband 2 in the position that protective clothing is located the waist, when medical personnel wear protective clothing, make protective clothing can hug closely medical personnel's health under the constraint of waistband 2, avoid producing great gap between human body and the protective clothing, lead to medical personnel when walking, moving, protective clothing produces and rocks, influence medical personnel's normal walking;

preferably, the position of the waist part behind the waist part on the waistband 2 is fixedly provided with the ventilation box 3, the ventilation box 3 is fixedly arranged on the waistband 2, so that the waistband 2 bears the gravity of the ventilation box 3 and cannot influence the normal walking of medical personnel, an air supply device and an air exhaust device are respectively arranged in the ventilation box 3 at intervals in the vertical direction, as shown in the attached figure 3, the air supply device is communicated with a sterilization box 4 arranged in the air exchange box 3, the sterilization box 4 is communicated with the head sleeve 1 through an air inlet pipe 39, the air inlet pipe 39 is arranged as a hard pipe in the ventilation box 3, and the end of the air inlet pipe 39 extending out of the ventilation box 3 is arranged as a soft pipe, and similarly, the end of the air outlet pipe 40 in the ventilation box 3 is arranged as a hard pipe and the end extending out of the ventilation box 3 is arranged as a soft pipe, as shown in the attached figure 1, the air inlet pipe 39 enters the head cover 1 from the upper part of the head cover 1, and the exhaust pipe 40 is communicated with the lower part of the head cover 1;

the air supply device and the air exhaust device are driven by a micro motor 5 arranged in the air exchange box 3, an opening and closing plate 6 which is respectively matched with the air supply device and the air exhaust device is rotationally arranged in the air exchange box 3, as shown in the attached drawing 1, a detection cover body 7 is arranged in the head sleeve 1, when a medical worker wears the protective clothing, the detection cover body 7 is buckled at the mouth and nose of the face (the shape of the detection cover body 7 is kept to be jointed with the outline of the mouth and nose of the human body, an air cushion is arranged at the contact position of the edge of the detection cover body 7 and the face of the human body to realize the air tightness of the detection cover body 7), so that the medical worker can complete normal breathing and inspiration through the detection cover body 7 (the detection cover body 7 can be fixed at the head position of the medical worker through a bungee cord, and can be fixed in other modes, and, initially, when the air supply device and the air exhaust device are not started to work, the opening and closing plate 6 is in a closed state, at this time, the outside air cannot enter the head cover 1 through the air supply device and the air exhaust device, after the medical care personnel wear the protective clothing, the oxygen in the air in the head cover 1 is continuously consumed along with the breathing, and then the oxygen content in the air in the head cover 1 is gradually reduced (the existing protective clothing has better sealing performance, so that the air permeability of the protective clothing is poor, so that the outside air cannot enter the head cover 1), so that when the oxygen content in the air in the head cover 1 is reduced to the extent that the normal breathing of the medical care personnel cannot be maintained, the arc frequency of the medical care personnel at the detection position of the respiration detection part of the respiration detection device arranged in the detection cover body 7 is accelerated (when the oxygen content in the air in the head cover 1 is reduced, the human body is ensured, so that when the breath detection device detects that the breathing frequency of the medical care personnel is increased to a certain degree, the micro-motor 5 is controlled by the micro-controller electrically connected with the breath detection device to start (the micro-motor 5 is electrically connected with the storage battery set in the ventilation box 3, and the micro-controller is electrically connected with the micro-motor 5 controller loop), the micro-motor 5 inputs outside air into the head cover 1 through the air supply device, and when the air supply device is started, the opening and closing plate 6 corresponding to the air supply device is opened synchronously, so that the outside air enters the sterilization box 4 to finish the sterilization and disinfection operation of the air (when the opening and closing plate 6 corresponding to the air supply device is opened, the trigger device arranged in the sterilization box 4 is triggered, so that the sterilization box 4 starts to work), and finally enters the upper position in the head cover 1 through the air inlet pipe 39, meanwhile, the micro motor 5 synchronously drives the air exhaust device to work and opens the opening and closing plate 6 corresponding to the air exhaust device, at the moment, air with lower oxygen content in the head cover 1 is outwards pumped out of the head cover 1, and the air in the head cover 1 forms convection under the action of the air supply device and the air exhaust device, so that the air with lower oxygen content in the head cover 1 can be quickly outwards exhausted, and the air with high external oxygen content is sent into the head cover 1;

along with the continuous feeding of the external fresh air, the oxygen content of the air in the headgear 1 gradually rises, at the moment, the oxygen content of the air breathed by the medical staff every time returns to the normal level, at the moment, the breathing detection device detects that the breathing frequency of the medical staff is reduced, so that when the respiratory rate returns to the normal state, the respiratory detection device controls the micro-motor 5 to stop working through the micro-controller electrically connected with the respiratory detection device, and the air supply device and the air exhaust device stop working, when the corresponding opening and closing plate 6 is synchronously closed and the opening and closing plate 6 corresponding to the air supply device is closed, the trigger device is not triggered any more, so that the sterilization box 4 stops working synchronously, so that when the oxygen content in the air in the head sleeve 1 is reduced again to the state that the normal breathing of the medical care personnel can not be maintained, the device starts again and repeats the process to achieve the effect of inputting fresh outside air into the headgear 1.

preferably, the microcontroller can be set with current parameters in different gradient ranges, so that when the current peak value detected by the ammeter is within a certain gradient range, the microcontroller controls the micro-motor 5 to operate according to corresponding power, and when the current peak value detected by the ammeter exceeds the gradient range, the microcontroller controls the power of the micro-motor 5 to be further increased (so that the amount of air input into the headgear 1 by the micro-motor 5 through the air supply device in unit time is increased), thereby achieving the effect of rapidly inputting outside fresh air into the headgear 1, and the exhaust device also improves the air exhausted outwards in unit time, and as the outside air continuously enters the headgear 1, the breathing frequency of medical staff is slowly reduced, the microcontroller correspondingly controls the micro-motor 5 to operate with reduced power, thereby reducing the fresh air input into the headgear 1 in unit time, the power consumption is reduced by running with lower power, so that the working time of the storage battery pack is prolonged;
