Dustproof helmet

The present invention relates to a dustproof helmet, and more particularly to a dustproof helmet that prevents dust or suspended particles and moisture in the air from entering the wear space and keeping the air inside the hat body clean.

Riding a locomotive with a helmet is a basic guarantee for the locomotive rider. However, in the face of the oncoming strong winds, and the dust and aerosols in the big cities, the helmet is almost useless.

The full-face helmet can provide better protection for the head of the locomotive knight. However, for the convenience of wearing, the opening below it is usually designed to be larger, so that the knight and the helmet are worn after wearing. There will still be gaps between the dust, and the dust will still enter the helmet through this gap. In order to overcome this situation, some people first hang up the mask and then bring a helmet, so that although it can achieve the effect of dust prevention, it still can't completely overcome the problem of dust or rain, especially when the wind speed is opposite to the speed of the locomotive. Under the influence of relative speed, it is more obvious. Moreover, for a locomotive knight who must wear glasses, after wearing a mask, the hot air that rises upwards will cause condensation on the cold lens, which will affect the line of sight, especially in rainy days. obvious.

As mentioned above, the conventional disadvantages have the following disadvantages:

1. Can not block the dust and aerosols in the air from entering the helmet;

2. Unable to stop rainwater from entering the helmet.

Therefore, how to solve the above problems and problems in the past, that is, the creators of the case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in order to effectively solve the above problems, the main purpose of the present invention is to provide a dustproof helmet that can filter dust or suspended particles in the air into the inside of the cap body.

The secondary purpose of this creation is to provide a dustproof helmet that prevents moisture from entering the interior of the cap.

The second objective of this creation is to provide a dustproof helmet that maintains the air inside the cap.

A secondary object of the present invention is to provide a dustproof helmet that maintains a pressure inside the cap that is positively pressured compared to the pressure outside the cap.

In order to achieve the above objective, the present invention provides a dustproof safety helmet, which comprises a cap body, a row of air outlets and a suction device, the cap body defines a wearing space, and has a receiving portion and an air suction port. The air outlet is located at a lower edge of the cap body, and the air inlet is spaced apart from the plurality of flaps, and a window is disposed at a front of the cap body to communicate with the wearable space, the air outlet is disposed at an edge of the window of the cap body and The air absorbing device is disposed in the accommodating portion, and has a fan and an air guiding tube. The fan has an exhaust side that communicates with the air vent and a suction side, and the air guiding tube has opposite two The ends respectively connect the suction side and the suction opening.

Through the structural design of the creation, when the wearer wears the dustproof helmet, the mask must first be completely lowered to close the entire window, so that the air inside and outside the cap cannot enter and exit from the window, and through the induction Connected to the air suction device, and when the sensor receives a signal, the operation of the air suction device is activated, when the air outside the cap passes through the air suction port during the ride of the wearer by the wearer The baffles block part of the dust or suspended particles or moisture in the air, and then the air enters the air duct so that the moisture in the air is retained in the air duct, and then the air that filters the dust and suspended particles and moisture passes through. The air suction side of the fan is then discharged from the exhaust side of the fan, and then discharged from the air outlet into the wearing space. By the arrangement of the blocking piece and the air guiding tube, the dust or the outside can be blocked. The suspended particles and moisture enter the wearing space of the cap body to achieve the effect of purifying the air inside the cap body.

In addition, after the window is closed by the mask, air inside and outside the cap body cannot be taken in and out of the window, and the air outside the cap body is filtered by the structure of the suction device disposed in the receiving portion. After being exhausted from the exhaust vent to the wearing space, the continuous circulation causes the pressure inside the cap to be greater than the pressure outside the cap to form a positive pressure state inside the cap compared to the outside of the cap. The air inside the cap body is kept clean, and the unfiltered air is excluded from the outside of the cap body, thereby maintaining the effect of purifying the air inside the cap body of the helmet.
