Description

Technical Field

[0001] The utility model relates to a fan, in particular to a fan with a solar power generation component suitable for outdoor use without an external power supply. Background Art

[0002] Electric fans are often referred to as fans. They use electric motors to drive the blades to rotate to speed up air flow. Fans are often used to cool or speed up air circulation. The continuous rotation of the fan blades requires a stable power supply. The stable power supply can be an external AC or DC power supply.

[0003] However, in most outdoor places, such as most camping sites, they are far away from residential areas and often lack a stable power supply. Or, even if people are prepared with power or backup power, the amount of power they carry is relatively limited, mainly for lighting, emergency and vehicle driving, and rarely for fans.

[0004] The utility model patent with application number 202320124593.7 discloses a multi-purpose fan for outdoor camping, whose polymer battery can provide power to drive the fan. However, considering that the volume of the polymer battery cannot be too large relative to the main structure of the fan, and a battery that is too large is not suitable for camping, the power carried by the battery of the multi-purpose fan for outdoor camping disclosed in the utility model patent is unlikely to maintain the long-term operation of the fan.

[0005] In other words, the limitation of power supply makes the existing fans unsuitable for use in outdoor places. Utility Model Content

[0006] The main advantage of the utility model is to provide a fan, so as to ensure that even in the outdoors, the rechargeable battery can be powered by the solar power generation component thereof and the fan can be continuously operated for a long time even in the outdoor places.

[0007] According to one aspect of the utility model, the fan of the utility model capable of achieving the aforementioned objects and advantages comprises:

[0008] a fan assembly;

[0026] Referring to the accompanying drawings of the present utility model Figures 1 to 4C , a fan according to an embodiment of the utility model is illustrated, which includes a fan assembly 10, a solar power generation assembly 20 and a rechargeable battery 30, wherein the rechargeable battery 30 is electrically connected to the solar power generation assembly 20 and the fan assembly 10, respectively, so that the rechargeable battery 30 can provide power to the fan assembly 10, and the solar power generation assembly 20 can charge the rechargeable battery 30. Preferably, the volume of the fan of the utility model is small, so as to be easy to carry and use outdoors. However, those skilled in the art will understand that the volume and shape of the fan of the utility model are not limited. It can be understood that the rechargeable battery 30 of the fan of the utility model can be any type of rechargeable battery. Preferably, the rechargeable battery 30 of the fan of the utility model is a polymer battery. Optionally, the rechargeable battery 30 of the fan of the utility model is a solid-state battery or a semi-solid-state battery. Optionally, the rechargeable battery 30 of the fan of the utility model is a lead-acid battery or a nickel-hydrogen battery.

[0027] As shown in the attached picture Figures 1 to 4C As shown, the fan assembly 10 and the solar power generation assembly 20 of the fan according to the embodiment of the utility model are pivotally connected together. Specifically, the fan assembly 10 of the fan of the utility model forms a first connection end 101 and a first free end 102 opposite to the first connection end 101, and the solar power generation assembly 20 forms a second connection end 201 and a second free end 202 opposite to the second connection end 201, wherein the first connection end 101 of the fan assembly 10 and the second connection end 201 of the solar power generation assembly 20 are pivotally connected together. As shown in the accompanying drawings Figures 1 to 4CAs shown, the fan assembly 10 of the fan according to the embodiment of the utility model has an air outlet side 100, and the solar power generation assembly 20 has a light receiving side 200, wherein the air outlet side 100 of the fan assembly 10 is formed on the outside of the fan assembly 10, and the light receiving side 200 of the solar power generation assembly 20 is formed on the outside of the solar power generation assembly 20.

[0028] As shown in the attached picture Figure 4A As shown, the first connection end 101 of the fan assembly 10 and the second connection end 201 of the solar power generation assembly 20 of the fan according to the embodiment of the utility model are pivotally connected together, so that the fan assembly 10 and the solar power generation assembly 20 of the fan of the utility model can be folded together and the air outlet side 100 of the fan assembly 10 and the light receiving side 200 of the solar power generation assembly 20 of the fan of the utility model are oriented in opposite directions and form two opposite sides. Accordingly, when the fan assembly 10 and the solar power generation assembly 20 of the fan of the utility model are folded together and the fan of the utility model is placed vertically, the air outlet side 100 of the fan assembly 10 and the light receiving side 200 of the solar power generation assembly 20 of the fan of the utility model are exposed, and the fan of the utility model can be started and blow air to the target object (such as a person enjoying the cool air). At this time, since the fan of the utility model is placed vertically, the light receiving side 200 of the solar power generation component 20 of the fan of the utility model is vertical or nearly vertical to the ground, even if the light receiving side 200 of the solar power generation component 20 of the fan of the utility model faces the direction of the sun (for example, the east or the south), the effective light receiving area of ​​the light receiving side 200 of the solar power generation component 20 of the fan of the utility model is small, so that the power generation power of the solar power generation component 20 of the fan of the utility model is relatively low. When the fan component 10 and the solar power generation component 20 of the fan of the utility model are folded together, and the fan of the utility model is placed horizontally so that the light receiving side 200 of the solar power generation component 20 of the fan of the utility model faces upward, the effective light receiving area of ​​the light receiving side 200 of the solar power generation component 20 of the fan of the utility model is large, and the power generation power of the solar power generation component 20 of the fan of the utility model is relatively high, which is conducive to the fan of the utility model charging the rechargeable battery 30 through the solar power generation component 20. At this time, since the air outlet side 100 of the fan assembly 10 of the utility model fan faces downward, when the utility model fan is placed on the ground, it will not be able to start and supply air to the target object; when the utility model fan is suspended in the air so that the target object is under the utility model fan, the utility model fan will be able to supply air to the target object while its solar power generation assembly 20 obtains relatively high power generation. Figure 4B and 4CAs shown, further, the first connection end 101 of the fan assembly 10 and the second connection end 201 of the solar power generation assembly 20 of the fan according to the embodiment of the utility model can be pivotally connected together, so that the fan assembly 10 and the solar power generation assembly 20 of the fan of the utility model can be unfolded and form a preset angle. It can be understood that the preset angle formed by the fan assembly 10 and the solar power generation assembly 20 of the fan of the utility model ranges from 0 to 180 degrees. As shown in the accompanying drawings Figure 4B and 4C As shown, when the fan assembly 10 and the solar power generation assembly 20 of the fan of the utility model are unfolded and form a proper angle, the fan of the utility model can be stably supported on a supporting surface (such as the ground) by the support of the fan assembly 10 and the solar power generation assembly 20. Figure 4B As shown, when the fan assembly 10 and the solar power generation assembly 20 of the fan of the utility model are unfolded, and the fan of the utility model is supported on a supporting surface through the side 15 of the fan assembly 10 and the side 23 of the solar power generation assembly 20, the fan assembly 10 and the solar power generation assembly 20 are respectively placed vertically. Then, even if the air outlet side 100 of the fan assembly 10 of the utility model fan and the light receiving side 200 of the solar power generation assembly 20 of the utility model fan are both exposed, and the light receiving side 200 of the solar power generation assembly 20 of the utility model fan faces the direction of the sun (for example, the east or the south), the effective light receiving area of ​​the light receiving side 200 of the solar power generation assembly 20 of the utility model fan is also small, so that the power generation power of the solar power generation assembly 20 of the utility model fan is relatively low. As shown in the accompanying drawings Figure 4CAs shown, when the fan assembly 10 and the solar power generation assembly 20 of the fan of the utility model are unfolded and form an appropriate angle, and the fan of the utility model is supported on a supporting surface through the first free end 102 of the fan assembly 10 and the second free end 202 of the solar power generation assembly 20, the air outlet side 100 of the fan assembly 10 of the utility model and the light receiving side 200 of the solar power generation assembly 20 of the utility model fan are both exposed, and the angle formed by the light receiving side 200 of the solar power generation assembly 20 of the utility model fan and the horizontal plane is greater than 90 degrees, resulting in a relatively larger effective light receiving area of ​​the light receiving side 200 of the solar power generation assembly 20 of the utility model fan and a greater power generation power. It can be understood that in order for the fan of the utility model to be stably supported on a support surface by the support of the first free end 102 of the fan assembly 10 and the second free end 202 of the solar power generation assembly 20, when the fan assembly 10 and the solar power generation assembly 20 of the fan of the utility model are unfolded, the appropriate angle formed is not less than 30.
