Description

A solar straw hat

technical field

The utility model relates to a straw hat, in particular to a solar straw hat.

Background technique

As a common item in people's daily life, straw hats have obvious seasonality. For example, straw hats suitable for summer wear are generally thinner and thinner, and their main functions are sunshade and cooling; while straw hats suitable for winter wear are thicker and mainly used to keep warm. Obviously, a straw hat that is suitable for summer is not suitable for winter, and vice versa. Therefore, people need at least two straw hats to meet the needs of different seasons of the year.

Contents of the invention

The technical problem to be solved by the utility model is to provide a solar straw hat, which utilizes solar energy to generate electricity, and has the functions of heating, cooling and lighting, and is suitable for wearing in all seasons.

The technical solution adopted by the utility model to solve the technical problem is: a solar straw hat, comprising a hat brim, a hat body and a hat top, characterized in that: the brim of the hat is a double-layer structure, the upper layer is a ring-shaped miniature photovoltaic module, and the lower layer is a Heat insulation layer I, a small electric fan is installed at the bottom of the heat insulation layer I; the cap body is a three-layer structure, the outer layer is the heat insulation layer II, the inner layer is the heat conduction layer I, and the middle layer is provided with a spiral Heating wire and temperature probe; the top of the hat is a double-layer structure, the outer layer is the heat conduction layer II, and the inner layer is the heat insulation layer III. The inside of the heat conduction layer II is equipped with a battery and a controller, and the top of the hat top is There are lights.

As a further improvement, a temperature setting panel is also provided on the top of the crown.

As a further improvement, a cooling and heating switch and a lighting switch are also provided at the bottom of the visor.

As a preference, the annular miniature photovoltaic module includes two groups of solar cells, each group of solar cells includes 6 to 8 pieces, and the solar cells are connected in series by photovoltaic ribbons, and the two groups The solar cells are connected in parallel by photovoltaic ribbons.

When the utility model is irradiated by sunlight, the ring-shaped miniature photovoltaic module on the visor of the hat will absorb sunlight and generate electricity. The generated electricity is controlled by a controller to charge the battery or directly drive the electric fan and heating wire to work. When the heating and cooling switch is connected to terminal 1 (see Figure 3), the straw hat is in heating mode, bringing warmth to people; at this time, the heating target temperature of the heating wire is adjusted through the temperature setting panel on the controller. Setting, the heating wire will heat towards the target temperature, and the temperature probe will monitor the temperature of the heating wire. When the heating wire reaches the target temperature, the controller will cut off the circuit according to the temperature signal of the temperature probe, and the heating wire will stop working. When the temperature of the heating wire is lower than the set target temperature, the controller will automatically switch on the circuit again, and the heating wire will start working again. When the heating and cooling switch is connected to terminal 3 (see Figure 3), the straw hat is in the cooling mode, and the two small electric fans work, bringing a little bit of coolness to people. When lighting is needed at night, the controller only needs to turn on the lighting switch, and the controller will control the battery to discharge to make the lighting work, bringing light to people and making it convenient for people to go out at night.

The controller of the utility model has three functions: (1) It has the function of MPPT (maximum power point tracking), which can monitor the working voltage and current of the miniature photovoltaic module in real time under the light, and adjust it so that it always works at the maximum power point; (2) Intelligently control the charging and discharging of the battery, and intelligently monitor the circuit. When the battery is fully charged and no electrical components are working, the circuit is automatically cut off, and when there are electrical components working, the circuit is automatically connected; (3) Control the heating wire to work, there is a temperature setting panel on it, when the straw hat is in the heating mode, you can manually set the heating target temperature, and monitor the temperature of the heating wire in the straw hat through the temperature probe, when the heating wire is working When the temperature exceeds the set target temperature, the controller automatically cuts off the circuit, and when the working temperature of the heating wire is lower than the set target temperature, the controller automatically turns on the circuit.

The allowable current of the fuse of the utility model is 3A; the working voltage of the storage battery is 4V, which matches the maximum voltage of the above-mentioned miniature photovoltaic module, and the rated capacitance is 4Ah; the rated voltage of the lighting lamp, the heating wire for heating and the electric fan for cooling are all 4V About, wherein the rated current of the lighting lamp and the heating wire is about 1A, and the rated current of the electric fan is about 0.5A. According to the selection of these electrical components, it can be seen that the battery can be fully charged by the miniature photovoltaic module working at the rated current for 2 hours; the fully charged battery can be used for lighting or heating wires to work continuously for 2 hours in the absence of light (the battery is discharged at a depth of 50%) , it can also be used for two small electric fans to work continuously for 2 hours at the same time; under weak light, the micro-photovoltaic module uses half of the rated power (that is, about 4.1W, because the working voltage and light intensity of crystalline silicon cells do not change much, and its working current It is approximately linearly proportional to the light intensity, so the halving of its power under weak light is due to the halving of its current, so at this time its current is about half of the rated current, which is about 1A, and its voltage is still about 4V). It can satisfy the normal operation of two small fans and the normal operation of the heating wire at the same time. Therefore, the aforementioned miniature photovoltaic modules can fully support the normal operation of the aforementioned electrical components.

The beneficial effects of the utility model are: the utility model is provided with a micro-photovoltaic module, which is light in weight, simple in structure and low in power, and integrates three electrical components of a heating wire, an electric fan and a lighting lamp through a simple structural design, It has three functions of heating, cooling and lighting. It can not only bring warmth to people in cold winter, but also cool people in hot summer. It can also provide light when people go out at night, so there is no seasonal restriction. It can be worn all year round; and it adopts a multi-functional controller, which can not only make the micro photovoltaic module work at the maximum power point, but also intelligently control the charging and discharging of the battery in the straw hat, intelligently cut off the circuit, and monitor the electric heating in real time The working temperature of the wire greatly improves the efficiency and safety of the circuit operation.
