Referring to fig. 1 and 4, the cap housing 10 has a heat dissipation groove 101, and the heat dissipation groove 101 is located inside the cap housing 10, i.e., the heat dissipation groove 101 is recessed outward from the inner surface of the cap housing 10; the cap shell 10 is provided with an air inlet 103 and a heat dissipation opening 104, and the air inlet 103 and the heat dissipation opening 104 both penetrate through the cap shell 10, so that air flows into the heat dissipation groove 101 from the air inlet 103 and flows out from the heat dissipation opening 104, and heat dissipation can be performed on the head of a user who wears the cap shell correspondingly.

This air intake 103 sets up in the front end to when the user moves ahead, the air flows towards the user, because the flow direction of air and the skew of air intake 103 direction are less, consequently be convenient for the air through air intake 103 get into in the heat dissipation recess 101, thereby improve the gas permeability of this safety helmet.

As a preferred technical solution, referring to fig. 1 and 4, the heat dissipation groove 101 extends from the front end to the rear end along the curved surface of the inner surface of the cap housing 10 through the top end. It should be noted that, when the user walks, the walking direction of the user is on the same vertical plane as the heat dissipation groove 101, and the change of the flow direction is small in the flowing process of the air, so that the air rapidly leaves from the heat dissipation opening 104, thereby improving the air permeability of the safety helmet and facilitating the heat dissipation.

Further, referring to fig. 1 and 4, the air inlets 103 are provided in plural numbers, and it should be noted that, for the same air, if the flow direction of the air is perpendicular to the distribution direction of the air inlets 103, the air flow rate of each air inlet 103 is the same, the air amount entering the heat dissipation groove 101 is larger; if the air flow direction is the same as the distribution direction of the air inlets 103, the flow velocity of the air inlets 103 gradually decreases along the air flow direction, resulting in a smaller amount of air in the heat dissipation groove 101. Therefore, the air inlets 103 are distributed along the width direction of the heat dissipation groove 101. In consideration of the overall strength of the safety helmet, the number of the air inlets 103 is preferably 3-6.

As a preferable technical solution, referring to fig. 1 and 4, a plurality of heat dissipation ports 104 are provided, and here, it should be noted that, in order to facilitate air separation at each position in the heat dissipation groove 101, the heat dissipation ports 104 are preferably provided along the extending direction of the heat dissipation groove 101 to improve the heat dissipation performance as a whole.

As a preferable technical solution, referring to fig. 1 and 4, the cap case 10 has a reinforcing part 102 and a general part, and the reinforcing part 102 corresponds to the heat dissipation groove 101, that is, the heat dissipation groove 101 is located on the reinforcing part 102 and the reinforcing part 102 passes through the top end and extends to the rear end along the inner surface curved surface of the cap case 10 from the front end. The thickness of the reinforcement part 102 is greater than that of the general part or the material thickness of the reinforcement part 102 is greater than that of the general part, so that the overall strength of the helmet can be improved. The reinforcing part 102 protrudes from the outer surface of the helmet shell 10 to reduce damage to the helmet.

As a preferred technical solution, referring to fig. 2 and 4, a baffle 20 is installed on the inner surface of the helmet shell 10, the baffle 20 is located at the front end of the helmet, and it should be noted that the heat dissipation groove 101 has an air inlet section corresponding to the air inlet 103, and the baffle 20 is covered on the air inlet section to isolate the air inlet 103 from the head of the user. Specifically, when the user wears the safety helmet, the forehead of the user abuts against the baffle 20, and when the baffle 20 does not seal the air inlet 103, the smoothness of the heat dissipation groove 101 can be ensured. Preferably, the baffle 20 is curved and attached to the head of the user to enhance the comfort of wearing the headgear.

Preferably, the visor 20 has a head end and a tail end, the head end of the visor 20 being adjacent to the front end of the helmet and the tail end of the visor 20 being adjacent to the rear end of the helmet. The head end is horizontal and is relatively fixed with the inner surface of the safety helmet, the tail end is far away from the inner surface of the safety helmet, and air is guided on the basis of isolating the head of a user from the air inlet 103, so that the integral air permeability is improved.
