This allows the airflow to enter and filter dust through the filter screen, thus purifying the airflow discharged into the cap body.

[0016] As a preferred embodiment of this utility model, the mounting base is provided with an adjusting nut that is threaded to the thread of the threaded adjusting head.

[0017] By adopting the above technical solution, the threads of the adjusting nut and the thread adjusting head are matched to ensure the stability of the thread rotation of the thread adjusting head.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] 1. This fan-equipped safety helmet is inserted into the outer side of the brim of the helmet body via a clamp. The fixed components facilitate the installation, fixing, and disassembly of the clamp and the helmet body. The fan inside the mounting cylinder operates to exhaust airflow, which is then discharged into various air ducts through connecting components. This achieves uniform airflow distribution, allowing the airflow to conform to the inner wall of the helmet body and be discharged upwards. Compared with existing technologies, this technology achieves airflow distribution and avoids airflow blowing directly onto the head, ensuring effective heat dissipation for the head.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 3 The safety helmet with a fan in this embodiment mainly includes a helmet body 1, a photovoltaic module 2, a mounting frame 3, a mounting cylinder 4, a fan 5, a clamping seat 11 and related components, an air duct 14 and related components, a connecting component, a mounting seat 7 and related components, etc.

[0027] The helmet body 1 is the main structure of the entire safety helmet, which plays a basic role in protecting the head. The photovoltaic module 2 is set on the upper surface of the helmet body 1. Its function is to absorb solar energy and convert it into electrical energy to provide power support for electrical components such as the fan 5. The photovoltaic module 2 usually uses high-efficiency photovoltaic panels, which are fixed to the upper surface of the helmet body 1 by means of adhesive or clips.

[0028] Mounting bracket 3 is located on the upper right side surface of cap body 1. It provides a mounting support platform for mounting cylinder 4. Mounting bracket 3 and cap body 1 can be fixed by welding or bolt connection to ensure that mounting bracket 3 is stably installed on cap body 1.

[0029] The mounting cylinder 4 is connected to the right side surface of the mounting frame 3. The fan 5 is fixed inside the mounting cylinder 4. The mounting cylinder 4 provides installation space for the fan 5 and also guides airflow. The mounting cylinder 4 and the mounting frame 3 can be tightly connected by means of flange connection or threaded connection to prevent airflow leakage.

[0030] Multiple clamping seats 11 are inserted into the outer edge of the cap body 1. These clamping seats 11 are evenly distributed on the outer edge of the cap body 1 and are used to fix the air duct 14 and other related components. Each clamping seat 11 is equipped with a fixing component, which includes a fastening nut 12 embedded and fixed to the upper surface of the clamping seat 11. The fastening nut 12 is internally threaded with a fastening screw 13 that passes through the clamping seat 11 and contacts the edge of the cap body 1. During installation, the clamping seat 11 is placed in a suitable position on the outer edge of the cap body 1, and then the fastening screw 13 is rotated so that its thread is screwed in and makes tight contact with the edge of the cap body 1. Through the locking action of the fastening nut 12, the clamping seat 11 is firmly fixed to the cap body 1. The clamping seat 11 can be made of plastic or metal materials and has a certain strength and toughness to ensure that it can stably fix the air duct 14 and other components.

[0031] A U-shaped air duct 14 is fixed to the outside of the clamping base 11. The other end of the air duct 14 is located inside the cap body 1 and fits against the inner wall of the cap body 1. The function of the air duct 14 is to evenly distribute and guide the airflow discharged from the fan 5 into the interior of the cap body 1, preventing the airflow from blowing directly onto the head. The air duct 14 can be made of lightweight and flexible materials, such as plastic hoses or rubber hoses, for easy installation and position adjustment.

[0032] A soft pad 17 is fixed to the outer surface of the air duct 14 at one end of the helmet body 1. The soft pad 17 can be made of soft materials such as sponge or silicone. When wearing the helmet, the soft pad 17 can prevent the air duct 14 from directly contacting the head, increase the comfort of wearing it, and reduce the pressure on the head.

[0033] The connecting assembly is used to connect the air duct 14 and the mounting bracket 3, so that the airflow discharged from the fan 5 can enter the air duct 14. The connecting assembly includes a semi-annular pipe 15 connecting the upper surface of the opening of the air duct 14 and a connector pipe 6 fixed to the left side of the mounting bracket 3 and connected to the mounting cylinder 4. A flexible hose 16 connected to the semi-annular pipe 15 and inserted into the connector pipe 6 is connected to the semi-annular pipe 6. The semi-annular pipe 15 can be made of plastic or metal and is semi-annular in shape. It can be connected to the upper end of the opening of multiple air ducts 14. The connector pipe 6 and the mounting cylinder 4 can be fixed by welding or threaded connection to ensure a tight connection. The flexible hose 16 can be made of rubber hose, which has a certain degree of flexibility and sealing, can be easily inserted into the connector pipe 6, and ensures that the airflow will not leak during transmission. When the fan 5 is working, the discharged airflow passes through the mounting cylinder 4, connector pipe 6, flexible hose 16, and semi-annular pipe 15 in sequence, and finally enters each air duct 14.

[0034] The mounting bracket 3 has a mounting seat 7 fixed on the right side, located outside the mounting cylinder 4 and open at the top. The mounting seat 7 is used to install the filter screen 8 and other related components. The mounting seat 7 and the mounting bracket 3 can be fixed by welding or bolt connection.

[0035] The mounting base 7 has an external threaded connection to a threaded adjusting head 9, which passes through into the mounting base 7. A mesh plate 10 is fixed to one end of the threaded adjusting head 9 inside the mounting base 7. A filter screen 8 is placed between the mesh plate 10 and the right opening of the mounting cylinder 4. The filter screen 8 can be made of materials such as metal mesh or fiber mesh. Its function is to filter dust and other impurities in the airflow entering the mounting cylinder 4, ensuring the cleanliness of the airflow discharged into the cap 1. When installing the filter screen 8, place it outside the right opening of the mounting cylinder 4, then rotate the threaded adjusting head 9 to screw in its threads and push the mesh plate 10 to move, pressing and fixing the filter screen 8 to the outside of the opening of the mounting cylinder 4 for sealing. An adjusting nut that matches the thread of the threaded adjusting head 9 is fixed on the mounting base 7. The adjusting nut ensures the stability of the thread rotation of the threaded adjusting head 9 and prevents it from loosening during use.

[0036] Structural design principles and usage steps:

[0037] Working principle

[0038] Photovoltaic module 2 absorbs solar energy and converts it into electrical energy to power fan 5. After fan 5 starts working, it draws in air from the outside. After the filter screen 8 filters out dust and other impurities, the clean airflow is discharged into the mounting cylinder 4. The airflow passes through connector pipe 6, hose 16, and semi-circular pipe 15 in sequence, and finally enters each air duct 14. Since the air duct 14 is U-shaped and fits the inner wall of the cap 1, the airflow flows in the air duct 14 and is evenly distributed. It is discharged upwards while fitting the inner wall of the cap 1, which realizes heat dissipation for the head and avoids the airflow blowing directly on the head, reducing discomfort to the head.

[0039] Usage steps,

[0040] Put the assembled helmet with fan on your head, adjust the position to ensure comfortable wear, and the photovoltaic module 2 will start working under sunlight to power the fan 5. After the fan 5 starts, it will start to exhaust airflow to dissipate heat from the head.
