A front mounting port is provided at the front of the helmet 1, the transparent hard mask 2 is arranged at the front mounting port, the flexible neck cover 3 is connected to the lower end of the helmet 1, side mounting ports are provided on both sides of the helmet 1, and two ear protection and noise reduction Bluetooth call headsets 4 are respectively arranged at the two side mounting ports; an exhaust hole 8 is provided on the helmet 1, and the air supply filtration system is connected to the helmet 1 and is used to transport filtered gas to the helmet 1 and the transparent hard mask 2.

[0028] The appearance of the helmet 1 in this embodiment is similar to that of ordinary electric vehicles and bicycles. A transparent hard mask 2 is provided at the front of the helmet 1. A flexible neck cover 3 is connected to the bottom of the helmet 1. The flexible neck cover 3 can fit the neck of the wearer to ensure the air tightness of the entire hood. Compared with the existing positive pressure biological protection hood, it can avoid the problem that it is difficult to ensure the air tightness of the entire hood due to the presence of the cover. While ensuring positive pressure protection, it will not be particularly noticeable after wearing, thereby improving the aesthetics and daily use of the positive pressure biological protection hood 100. In addition, by providing an ear protection and noise reduction Bluetooth call headset 4, the wearer can make wireless calls with the outside world.

[0029] Specifically, the exhaust hole 8 is provided at the lower part of the helmet 1, and the air supply and filtering system is connected to the upper part of the helmet 1. In this embodiment, two exhaust holes 8 are provided, and both of them correspond to the position of the wearer's chin.

[0030] The air supply filtering system includes a fan 5, an air supply pipe 6 and a filter device 7. The two ends of the air supply pipe 6 are respectively connected to the fan 5 and the upper part of the helmet 1, and the filter device 7 is arranged in the air supply pipe 6. In this embodiment, the filter device 7 is arranged in the air supply pipe 6 at one end close to the helmet 1.

[0031] In order to make the air supply and filtration system convenient for the wearer to carry, a waist belt or a brace is provided on the blower 5. When in use, the wearer fixes the blower 5 through the waist belt or the brace.

[0032] A fixed power supply is provided outside the fan 5, and the fixed power supply is used to supply power to the fan 5. By providing the fixed power supply, the positive pressure biological protection hood 100 can work continuously for 6 hours.

[0033] The air supply filtration system further includes a controller, an air volume sensor, an abnormal power alarm indicator 10, and an abnormal air supply volume alarm indicator 11. The air volume sensor is arranged in the air supply pipe 6 and is located between the fan 5 and the filter device 7. The abnormal power alarm indicator 10 and the abnormal air supply volume alarm indicator 11 are both arranged on the upper part of the helmet 1. The fixed power supply is connected to the controller through a battery power detection module. The air volume sensor, the abnormal power alarm indicator 10, and the abnormal air supply volume alarm indicator 11 are all connected to the controller. The controller in this embodiment is arranged outside the fan 5.

[0034] The air volume sensor can monitor the air volume and transmit the data to the controller. The controller determines whether the air volume is insufficient. If it is insufficient, the abnormal air volume alarm indicator 11 is controlled to turn red and flash. The battery power detection module can detect the power of the fixed battery and transmit the data to the controller. The controller determines whether the power of the fixed power source is insufficient. If it is insufficient, the abnormal power alarm indicator 10 is controlled to turn red and flash.

[0035] When the positive pressure biological protection hood 100 is in working state, the inside is in positive pressure state relative to the outside of the helmet 1, and the pressure difference can reach up to 20 Pa. The fan 5 delivers air to the inside of the helmet 1 through the air supply pipe, and the exhaust hole 8 discharges the gas exhaled by the human body in the helmet 1 to the outside of the helmet 1.

[0036] When the positive pressure biological protection hood 100 is working normally, the abnormal power alarm indicator 10 and the abnormal air supply volume alarm indicator 11 remain turned off. When the fixed power supply is insufficient, the abnormal power alarm indicator 10 turns red and flashes to serve as a reminder. When the air supply volume is insufficient, the abnormal air supply volume alarm indicator 11 turns red and flashes to serve as a reminder.

[0037] The positive pressure biological protection hood 100 in this embodiment can be used once or repeatedly after being sterilized.

[0038] Specifically, the lower part of the helmet 1 is provided with a water pipe hole 9, which is used to insert a water pipe for drinking water. The water pipe hole 9 in this embodiment corresponds to the position of the wearer's chin, and the water pipe hole 9 is located between the two exhaust holes 8.

[0039] like Figure 5 As shown, the ear protection and noise reduction Bluetooth call headset 4 includes a memory foam ear pad 41 and a sound insulation and noise reduction material layer 43 arranged outside the memory foam ear pad 41, and a Bluetooth call module 42 is wrapped in the sound insulation and noise reduction material layer 43. The Bluetooth call module 42 in this example can be connected using Bluetooth 5.2 and above to achieve calls between different positive pressure biological protection hoods 100 and between the positive pressure biological protection hood 100 and the central control room.

[0040] The soft and skin-friendly memory foam ear pad 41 contacts the wearer's ear, making the wearer more comfortable. At the same time, the noise transmitted to the human ear is less than 30dB(A) by using the sound insulation and noise reduction material layer 43.

[0041] Specifically, the transparent hard mask 2 is an outwardly convex arc structure, so that the interior of the transparent hard mask 2 has enough space to enable the wearer to wear the glasses easily.

[0042] In this specific embodiment, the helmet 1 is made of carbon fiber resin-based composite material or ABS material. The helmet 1 is integrally formed, has a light weight, a daily appearance, good protection effect and is comfortable to wear.

[0043] In this specific embodiment, the transparent hard mask 2 is made of reinforced PC material, which has the functions of wear resistance, anti-fog and sun protection, can resist strong light, prevent glare, and has a light transmittance of 90%.

[0044] In this specific embodiment, the flexible neck cover 3 is made of silver fiber knitted cloth, which is soft, thin, and has certain antibacterial and antiviral effects, further preventing pathogenic microorganisms from entering the interior of the helmet 1.
