SOLAR-POWERED VENTILATED HAT WITH LIGHT CHASING FUNCTION

Abstract

A solar-powered ventilated hat with light-chasing function comprising an inner hat body to be worn on the head and an outer hat body pivotally connected to the inner hat body. The inner hat body is designed as meshed and a plurality of positioning ribs are disposed on its surface. On the top edge of the outer hat body are disposed a fan and a servomotor pivotally connected to the top edge of the inner hat body. A light-detecting part, a solar panel and a control circuit are disposed on the brim of the outer hat body. The solar panel is electrically connected to the fan and the servomotor. When the hat is worn, the light-detecting part detects sunlight and drives the servomotor to rotate the outer hat body so that the solar panel can face sunlight directly to generate adequate electric power supply for the fan. Exterior air is guided by the fan inside the hat and distributed on the head by the inner hat body to form convection and make the head comfortable and dry.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a solar-powered ventilated hat with light-chasing function, particularly to a solar-powered ventilated hat with light-chasing function which can guide exterior air inside the hat to keep the head comfortable and dry and whose solar panel can face sunlight directly to generate adequate electric power supply for the fan.

2. Description of Related Art

In summer when the sun is bright, one would usually wear all kinds of hats to prevent the head from being directly exposed to sunlight. However, existent hats are poorly ventilated when in use. Feeling hot and windless for lack of ventilation, the user would sweat constantly in the head and even wet the hair. Such a ventilation problem may be improved by equipping the hat with a small fan which can guide exterior air inside the hat to form convection. But then the power supply for the fan would become a big issue. Although current technique employs a solar panel to absorb sunlight and convert it into electric power, if the solar panel does not face the sunlight directly for a long time as the user moves, the fan would not be able to work properly. In light of this, with several years of experiences in related business and after constant research and experiment, the applicant has invented a solar-powered ventilated hat with light-chasing function whose solar panel can face sunlight directly to generate adequate electric power supply for the fan.

SUMMARY OF THE INVENTION

The primary object of the present disclosure is to provide a solar-powered ventilated hat with light-chasing function so that when the hat is in use exterior air can be guided inside the hat to make the head comfortable and dry and so that the solar panel disposed on the hat can face sunlight directly to generate adequate electric power supply for the fan.

The foregoing solar-powered ventilated hat with light-chasing function comprises an inner hat body and an outer hat body pivotally connected to the inner hat body. The inner hat body is designed as meshed, and a plurality of positioning ribs are disposed on its surface. On the top edge of the outer hat body are disposed a fan and a servomotor pivotally connected to the top edge of the inner hat body. On the brim of the outer hat body are disposed a light-detecting part, a solar panel and a control circuit. The solar panel is electrically connected to the fan and the servomotor. When the hat is worn, sunlight is detected by the light-detecting part to drive the servomotor and cause the outer hat body to rotate. The rotation of the outer hat body keeps the solar panel facing sunlight directly to generate adequate electric power supply for the fan. Exterior air is guided inside the hat by the fan and distributed to the head by the inner hat body to form convection. In this manner the head is comfortable and dry.

The foregoing solar-powered ventilated hat with light-chasing function, wherein a through hole is disposed on the top edge of the outer hat body. On the bottom edge of the through hole is disposed a retaining base whereon is disposed the fan and the servomotor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer both to FIG. 1 and FIG. 2 and also FIG. 3, which are respectively a three-dimensional view, a breakdown three-dimensional view, and a cross-sectional view of the present invention. As shown in the figures, the present invention comprises an inner hat body 1 to be worn on the head and an outer hat body 2 pivotally connected to the inner hat body 1. The inner hat body is designed as meshed, and on its surface is disposed a plurality of positioning ribs 11 which extend downwards from the top. The inner hat body 1 is fixed in shape with an adjusting structure 12 (such as a buckle or a Velcro band) disposed on its rear edge for adjusting the width of the inner hat body 1. On the top edge of the outer hat body 2 is disposed a through hole 21 on the bottom edge thereof is disposed a retaining base 22. A fan 23 and a servomotor 24 are disposed on the retaining base 22. The servomotor 24 is pivotally connected to the top edge of the inner hat body 2. On the brim 25 of the outer hat body 2 is disposed a light-detecting part 26, a solar panel 27 and a control circuit 28. The solar panel 27 is electrically connected to the fan 23 and the servomotor 24.

The foregoing parts constitute a solar-powered ventilated hat with light-chasing function. When the hat is worn, the solar panel 27 absorbs sunlight and converts light energy into electric power. The fan 22 is driven by the control circuit 28 to guide exterior air inside the hat by way of the through hole 21. The inner hat body 1 then distributes the air to the head to form convection and make the head comfortable and dry. The light-detecting part 26 is used to detect sunlight and drive the servomotor 24 to rotate the outer hat body 2 along the inner hat body 1 so that the solar panel 27 faces sunlight directly all the time to generate adequate electric power supply for the fan 22. In this manner, the fan 22 can work properly and keep the head comfortable and dry for a long period of time.

Please refer to FIG. 4 and FIG. 5, respectively a drawing of the present invention in use and a drawing of the present invention in movement. Please also refer to FIG. 2 and FIG. 3. As these figures show, when the present invention is used, the inner hat body 1 is worn on the head and the width of the inner hat body 1 is adjusted by means of the adjusting structure 12 on the rear edge to accommodate the user's head. The outer hat body 2 provides sun-shading when the present invention is used. The solar panel 27 disposed on the brim 25 of the outer hat body 2 absorbs sunlight and converts light energy into electric power. The fan 22 is driven by the control circuit 28. The rotation of the fan 22 guides exterior air inside the hat by way of the through hole 21. The air is then distributed to the head by the inner hat body 1 and discharged out of the hat to form convection. In this manner sultry air is not amassed on the user's head and the head is comfortable and dry.

Please refer to FIG. 5 now. The fan 22 of the present invention is powered by the solar panel 27, so the solar panel 27 needs to face sunlight directly to maximize conversion efficiency. The light-detecting part 26 on the brim 25 of the outer hat body 2 will constantly detect the strength of sunlight and deliver signals to the control circuit 28 which interprets the signals. According to the detection signals of the light-detecting part 26, the servomotor 24 is then driven to turn clockwise or counter-clockwise to rotate the outer hat body 2 right or let along the inner hat body 1, so that the solar panel 27 on the brim 25 faces sunlight directly all the time to maximize conversion efficiency between light energy and electric power. In this manner, the fan 22 can work properly with adequate electric power and can constantly guide exterior air inside the hat. The air is then distributed to the head by the inner hat body 1 and discharged out of the hat to form convection to make the head comfortable and dry. The fan 22

With the design of light-chasing function, the present invention maximizes the electric power conversion efficiency of the solar panel 27. Without use of a rechargeable battery (the hat will become over-heavy with a battery), the hat is easy to wear and power supply is not a worry.
