Description

Technical Field

[0001] The utility model relates to the technical field of safety helmets, in particular to a safety helmet with a heat dissipation function. Background Art

[0002] A safety helmet is a hat that protects the head from injuries caused by falling objects and other specific factors. The safety helmet consists of a helmet shell, a hat lining, a chin strap and accessories. Safety helmets generally adopt an elliptical or hemispherical thin shell structure. This structure will produce a certain pressure deformation under impact pressure. Due to the rigidity of the material, it absorbs and disperses the force. In addition, the smooth surface and circular curve make it easy for the impact object to slide away, thereby reducing the impact time. According to the needs and to strengthen the strength of the helmet shell, the shell can be made into a variety of types such as a smooth top, a top rib, with a brim or without a brim.

[0003] According to a protective helmet disclosed in a Chinese patent with the announcement number "CN209594827U", a solar panel is embedded on the top of the reinforced helmet body. The utility model has a reasonable structural design, a small size, and is easy to carry. At the same time, multiple functions are integrated into the inside of the device, which is highly practical. The solar charging design is adopted to improve the resource utilization effect of the device, and the heat dissipation is good, which is convenient for long-term wearing. The above-mentioned helmet dissipates heat by installing a fan in front of the helmet. However, when the user's head fits the helmet, this heat dissipation method makes it impossible to discharge the heat on the top of the helmet because there is no gap between the head and the helmet, resulting in a poor heat dissipation effect. Therefore, a helmet with heat dissipation function is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a safety helmet with a heat dissipation function in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a safety helmet with heat dissipation function, comprising a helmet shell, on which a heat dissipation mechanism is arranged;

[0006] The heat dissipation mechanism includes a ring plate and a fixed cylinder, the ring plate is provided with an air duct groove, the upper surface of the ring plate is provided with a mounting groove, the mounting groove is provided with an air outlet, an annular filter is fixedly installed inside the mounting groove, a fan is fixedly installed inside the fixed cylinder, and a first dust filter is fixedly installed inside the fixed cylinder.

[0007] Preferably, a mounting hole is opened on the outer wall of the cap shell, the fixing tube is fixedly installed inside the mounting hole, and the ring plate is fixedly installed on the inner wall of the cap shell. The setting of the mounting hole can facilitate the fixing of the fixing tube on the cap shell.

[0008] Preferably, a battery box is fixedly mounted on the outer wall of the cap shell, and batteries are fixedly mounted inside the battery box. The battery can be used to supply power to the fan so that the fan can operate.

The number of the air outlet holes is fourteen, and the fourteen air outlet holes are evenly spaced inside the mounting groove, and the air outlet holes are connected to the air duct groove. The air inside the helmet shell can be discharged through the arrangement of the ventilation hole and the second dust filter.

[0010] Preferably, a supporting mechanism is provided on the ring plate, and the supporting mechanism includes a ring groove and a fixing ring. The ring groove is opened on the inner wall of the ring plate, and the fixing ring is fixedly installed inside the ring groove. The setting of the supporting mechanism allows a certain gap to be maintained between the user's forehead and the ring plate.

[0011] Preferably, rubber blocks are fixedly mounted on the inner wall of the fixing ring, the number of the rubber blocks is twenty-four, and the twenty-four rubber blocks are fixedly mounted on the inner wall of the fixing ring at equal intervals. The arrangement of the rubber blocks can facilitate the circulation of air inside the cap shell.

[0012] The utility model adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. The safety helmet with heat dissipation function operates through the cooperation between the ring plate, the fixing tube, the fan, the first dust filter, the air duct groove, the mounting groove, the annular filter and the air outlet.
