The fan 4 is preferably a micro blower which performs ventilation and exhaust through rotation of an impeller, generates wind power two to three times as much as that of a blade fan, thereby forming strong cooling wind power, and compared with a conventional blade fan, the micro blower can seal the impeller, does not coil hair after being worn, does not hurt hair style, and is safe. In addition, the motor of the fan 4 adopts a permanent magnet brushless motor, so that the power consumption is low, the silence performance is good, the stability is strong, noise is not generated, and the vibration of the cap 1 is not caused, thereby being beneficial to improving the comfort of users.

The control circuit is arranged in a controller 5, the controller 5 is arranged at the lower edge of one side of the helmet body 2 in a matching mode, the controller 5 is provided with a control key used for operating and triggering the control circuit, and the control circuit can be conveniently controlled to open and close the fan 4 after the cap 1 is worn. Preferably, the control circuit is preferably a 6V-grade small PCB, the PCB does not harm human bodies due to no electric wave, and the PCB can output voltage, the control key is pressed to output 3.5V voltage for low gear for the first time, the control key is pressed to output 4V voltage for low gear for the second time, the control key is pressed to output 6.2V voltage for high gear for the third time, and the control key is pressed for the fourth time to shut down, so that the fans can be divided into four gears through the operation of the controller, namely, one gear is pressed to keep out the wind, the other gear is pressed to keep out the wind, and the other gear is pressed to shut down.

The surface of the inner head sleeve 3 is hollowed, the hollowed structure can play a role in ventilation, and the toughness of the inner head sleeve 3 can be improved, so that the head shape of a user can be more adaptive after wearing the inner head sleeve. It should be noted that the surface of the inner head cover 3 may be hollowed out to have any pattern, such as a ring-shaped net structure, and is not limited to the shape shown in fig. 2 and 5. In addition, the inner head cap 3 is preferably made of plastic, the side of the inner head cap 3 is provided with an adjusting buckle for adjusting the inner diameter of the inner head cap, preferably, the adjusting buckle may be as shown in fig. 5, the side of the inner head cap forms a gap, one side of the gap is extended to form a connecting band 34, the other side of the gap is extended to form an adjusting band 33, the connecting band 34 is provided with fixing holes (not shown in the drawings), the adjusting band 33 is provided with a plurality of positioning protrusions 331 along the length direction thereof, the tail end of the positioning protrusions 331 forms a positioning portion 332 with a diameter slightly larger than that of the fixing holes, when the inner diameter of the inner head cap 3 needs to be adjusted, one of the positioning protrusions 331 is pressed, so that the positioning portion 332 at the end of the positioning protrusion 331 penetrates through the fixing holes, by this way, the inner diameter of the inner head cap 3 can be changed, so that the inner head cap 3 can adapt to different head shapes of users, thereby accurately fastening on the head of the user, avoiding falling or shaking, and simultaneously improving the wearing comfort.

As shown in fig. 4, the helmet body 2 and the inner headgear 3 may be fixedly connected by a plurality of protruding fixing posts 31 disposed on the periphery of the inner headgear 3, and a plurality of recessed threaded holes disposed on the end surface of the fixing posts 31, and the threaded holes are connected with screws 32 in an adaptive manner. During installation, after all the screws 32 penetrate through the helmet body 2, the screws are respectively connected with the threaded holes of the fixing columns 31 of the inner helmet sleeve 3, so that the helmet body 2 and the inner helmet sleeve 3 can be fixedly connected, a ventilation gap is formed between the helmet body 2 and the inner helmet sleeve 3 through the limitation of the fixing columns 31, and both the power supply and the fan 4 can be positioned in the gap; and then the helmet body 2 is fixed in the cap 1, thus completing the installation of the utility model. Preferably, when the hat 1 is made of a fabric material, the plurality of cloth belts 21 are directly added, two ends of each cloth belt 21 respectively penetrate through the two through holes formed in the surface of the helmet body 2, and then two ends of each cloth belt 21 are sewn on the hat 1, so that the helmet body 2 and the hat 1 can be connected to form a fixed whole in a manner of sewing through the cloth belts 21. When the cap 1 is made of plastic material, the cap 1 and the helmet body 2 may be fixed together in the same way as the inner head cap 3 and the helmet body 2, and the inner wall of the cap 1 is provided with a raised fixing post 31, and then a screw 32 is inserted through the hollow position of the inner head cap 3 and then inserted through the helmet body 2 to connect with the fixing post 31 of the cap 1, so as to complete the fixation of the helmet body 2 and the cap 1. Therefore, the structure of the utility model is suitable for the hats of various materials and shapes, such as peaked cap, motorcycle helmet or cloth hat, etc., which can be used together to achieve the general purpose. In addition, in the structure of the utility model, the fan 4 is sealed in the cap 1, so that the fan 4 is prevented from being exposed, and the aesthetic feeling of wearing can be improved.

In summary, after the hat is assembled with the hat, the hat 1 can be connected inside and outside to form a three-layer three-to-one structure, wherein the first layer is the body structure of the hat 1; the second layer (i.e. the inner middle layer) is the helmet body 2, and the fan 4, the power supply, the control circuit and the controller 5 are all fixed to the helmet body 2, which is equivalent to the helmet body 2 being an inner support; the third layer is an inner head sleeve 3 with a hollow structure and is used for being worn on the head of a user. After the cap 1 provided with the utility model is worn, cool air sent by the fans 4 at the two sides and the back of the helmet body 2 can blow to the two sides of the head and the position behind the head, so that the two sides of the head and the position from the back of the head to the back of the head have cool feeling. Compared with the state that the head is tightly wrapped by the traditional cap, the cap is favorable for air flow circulation through the gap formed between the inner head cover 3 and the helmet body 2, so that the use cool feeling is improved. In addition, the double-layer structure of the helmet body 2 and the inner head cover 3 can also play a role in protecting the head, thereby improving the safety.

The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
