[0030] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0031] The present invention provides an air convection heat dissipation protective suit, comprising an integrated suit that surrounds and forms a sealed space for epidemic prevention doctors to wear; the suit is provided with an air inlet 100 and an air outlet 200, which are respectively connected to the sealed space; an exhaust fan 101 is provided in the air inlet 100, which draws external air into the sealed space; an exhaust fan 201 is provided in the air outlet 200, which draws air from the sealed space to the outside;

[0032] The exhaust fan 101 is located on the outside of the air inlet 100, and a filter structure is provided on the inside of the air inlet 100. The filter structure is provided with a filter cotton layer 102 soaked in alcohol. The filter cotton layer 102 is laid along the width direction of the air inlet 100. The filter cotton layer 102 disinfects the air entering the enclosed space through the air inlet 100.

[0033] The set has a back section opposite to the back and a hip section opposite to the hips. The air inlet 100 is located at the lower part of the hip section and is arranged downwards, while the air outlet 200 is located on the back section and is arranged away from the back.

[0034] The aforementioned air convection cooling protective suit features an air inlet 100 at the lower part of the hip section, with an exhaust fan 101 inside. The exhaust fan 101 draws outside air into the sealed space through the air inlet 100. Simultaneously, an air outlet 200 is provided at the back section, with an exhaust fan 201 inside. The exhaust fan 201 draws air from the sealed space to the outside through the air outlet 200. Furthermore, a filter structure is provided inside the air inlet 100 to disinfect the air drawn into the sealed space. This not only ensures the effectiveness of epidemic prevention but also allows the protective suit to be breathable, preventing the epidemic prevention doctors from feeling stuffy.

[0035] An isolation mesh 103 is provided on the outer side of the air inlet 100 to prevent debris from entering the air inlet 100. An exhaust fan 101 is located between the isolation mesh 103 and the filter structure. In this way, the isolation mesh 103 can prevent solid matter from entering the enclosed space, avoiding discomfort for epidemic prevention personnel. At the same time, the exhaust fan 101, positioned between the isolation mesh 103 and the filter structure, does not directly draw in outside air; instead, it draws in air that has already undergone preliminary filtration by the isolation mesh 103, thus improving the filtration effect.

[0036] The hip section has a rigid, thickened hip area 104, with an air inlet 100 located within it; the back section has a rigid, thickened back area 105, with an air outlet 200 located within it. In this way, both the air outlet 200 and the air inlet 100 are located within the thickened areas, preventing the back of the epidemic prevention doctor from directly contacting the air outlet 200 and the hip from directly contacting the air inlet 100, effectively improving the doctor's comfort. Simultaneously, since a large amount of air passes through the air outlet 200 over a long period, some imperfectly filtered dust inevitably accumulates there; this is prevented from being directly exposed to by the doctor, avoiding soiling their clothing. Furthermore, the thickened areas provide space for the installation of multifunctional structures.

[0037] In this embodiment, the inner wall of the air inlet 100 is recessed outward to form a grooved ring 106. A rubber tube 107 is embedded in the grooved ring 106 and is arranged around the circumference of the grooved ring 106. The rubber tube 107 has an inner tube for storing alcohol. The outer periphery of the filter cotton layer 102 is embedded in the grooved ring 106 and abuts against the inner ring sidewall of the rubber tube 107.

[0038] The hose 107 is arranged in the grooved ring 106. The air drawn in from the outside by the exhaust fan 101 enters the hose 107 after passing through the air inlet 100. The hose 107 is provided with a filter cotton layer 102 containing alcohol, which can effectively disinfect and sterilize the incoming air.

[0039] The inner ring sidewall of the tubing 107 is provided with multiple capillary pores 108. The outer periphery of the filter cotton layer 102 abuts against the capillary pores 108, and the alcohol in the inner channel seeps out into the filter cotton layer 102 through the capillary pores 108. In this way, the filter cotton layer 102 abuts against the capillary pores 108. The capillary pores 108 are tiny holes, which allow the alcohol in the inner channel to slowly enter the filter cotton layer 102 through the capillary pores 108, ensuring the disinfection and sterilization effect of the filter cotton layer 102.

[0040] An elastic sealing layer 109 is filled between the outer ring sidewall of the tubing 107 and the bottom of the grooved ring 106, sealing the gap between them. This sealing layer 109 effectively seals the gap between the outer ring sidewall of the tubing 107 and the bottom of the grooved ring 106, preventing gas from entering the sealed space from the outside. Instead, gas enters through the tubing 107 and the filter layer 102. Simultaneously, it effectively fixes the position of the tubing 107 within the grooved ring, ensuring its secure connection to the grooved ring 106.

[0041] The tubing 107 has a side wall located between the inner ring side wall and the outer ring side wall. A side wall gap exists between the side wall and the side wall of the grooved ring 106. The outer periphery of the filter cotton layer 102 is embedded into this side wall gap, filling it completely. The side wall gap is filled with the filter cotton layer 102, which contains alcohol. Thus, air entering the sealed space through the side wall gap will be disinfected by the alcohol, ensuring the protective effect of the protective clothing.

[0042] The kit includes a liquid-filling chamber 110 for filling with alcohol. The liquid-filling chamber 110 is located above the air inlet 100, and a connecting pipe 111 extends from the bottom of the liquid-filling chamber 110. The connecting pipe 111 is concealed inside the kit and connects to the top of the tubing 107. The alcohol in the liquid-filling chamber 110 fills the inner tube of the tubing 107 through the connecting pipe 111. The liquid-filling chamber 110 serves to store alcohol, ensuring that the filter cotton layer 102 contains alcohol for a long time, thus maintaining the disinfection effect of the filter cotton layer 102. Simultaneously, alcohol can enter the tubing 107 through the connecting pipe 111, allowing the alcohol to permeate the filter cotton layer 102 and ensuring the effectiveness of epidemic prevention.

[0043] An inner opening is formed on the inner wall of the air inlet 100, and a flexible membrane layer 112 is sealed on the inner wall of the kit. The outer periphery of the flexible membrane layer 112 is arranged around the outer periphery of the inner opening of the air inlet 100, and the flexible membrane layer 112 covers the inner opening of the air inlet 100.

[0044] The flexible membrane 112 has multiple vent holes, which are distributed throughout the entire flexible membrane 112. When the exhaust fan 101 introduces external air into the sealed space through the air inlet 100, the flexible membrane 112 bulges into a spherical shape.

[0045] When the exhaust fan 101 draws a large amount of external gas into the sealed space, the external air enters the inner opening of the air inlet 100 and impacts the flexible membrane layer 112. The flexible membrane layer 112 is impacted by a large amount of gas, causing it to be unable to expel air in time through the multiple through holes 113. It then bulges out in the direction of gas movement. Because it is bulging out in the direction of gas movement, the multiple through holes 113 are facing different directions. The gas enters the sealed space from all directions through the multiple through holes 113, effectively changing the single direction of gas movement and effectively increasing the flow of gas in the sealed space.

[0046] Multiple flexible membrane tubes 114 are provided on the flexible membrane layer 112. The flexible membrane tubes 114 are hollow. The inner end of the flexible membrane tube 114 is connected to the flexible membrane layer 112 and is aligned and connected with the vent hole. The flexible membrane tube 114 is arranged outward and unsupported.

[0047] When the exhaust fan 101 introduces external air into the sealed space through the air inlet 100, the external air enters the flexible membrane tube 114 through the through hole 113, causing the flexible membrane tube 114 to float and swing, and is blown into the sealed space through the flexible membrane tube 114.

[0048] When external air enters the flexible membrane tube 114, the flexible membrane tube 114 will move around with the flow of the internal gas. The flexible membrane tube 114 has a connecting port that connects to the sealed space. Gas can enter the sealed space through the connecting port. The connecting port will change its spatial position as the flexible membrane tube 114 moves, thereby changing the direction of the air blown out of the air inlet 100 into the sealed space, effectively increasing the flow of gas in the sealed space.

[0049] The inner wall of the kit has an outer ring body 115 protruding from it. The outer ring body 115 is arranged around the outer periphery of the inner opening. The outer periphery of the flexible membrane layer 112 is fixed on the outer ring body 115. The outer ring body 115 has a plurality of curved channels 116 arranged around the circumference of the outer ring body 115. The curved channels 116 are arranged to bend along the circumference of the outer ring body 115. The inner end of the outer ring body 115 is connected to the air inlet 100, and the outer end of the outer ring body 115 is connected to the sealed space.

[0050] As the exhaust fan 101 introduces external air into the sealed space through the air inlet 100, the air blown out of the air inlet 100 is blown into the sealed space along the curved channel 116 and is blown out in a spiral pattern around the outer circumference of the outer ring body 115, forming a spiral airflow.

[0051] An outer ring body 115 is provided with an inner opening. Air blown out from the inner opening can enter the curved channel 116 of the outer ring body 115 and be blown out from the curved channel 116. The air is blown out in a spiral pattern around the outer circumference of the outer ring body 115, forming a spiral airflow, which effectively increases the flow of gas in the enclosed space.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
