Description

Technical Field

[0001] The utility model relates to the technical field of solar energy utilization, and particularly relates to a sunshade umbrella. Background Art

[0002] In order to improve the comfort of using a sunshade umbrella, in the related art, a solar cell is selected to be arranged on the umbrella surface, and then a fan is electrically connected. During the use by a user, the electric power generated by the solar cell is used to drive the fan to rotate, thereby bringing a cooler use experience. However, considering the portability and size of the umbrella, the size of the fan is not made too large, so the wind force is limited. Content of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a sunshade umbrella, which adds an ion wind generator on the basis of a fan, and can improve the wind force.

[0004] The sunshade umbrella according to an embodiment of the utility model includes an umbrella handle, a circuit board, an umbrella surface, a solar power generation film, a fan and an ion wind generator. The umbrella handle is of a hollow structure, the circuit board is installed inside the umbrella handle, the umbrella surface is connected to the umbrella handle, the solar power generation film is installed on the outer surface of the umbrella surface, the solar power generation film is electrically connected to the circuit board, and the solar power generation film is used to supply power to the sunshade umbrella. The fan is electrically connected to the circuit board, the fan is installed on the umbrella handle, and the fan is used to rotate to generate a first air flow. The ion wind generator is electrically connected to the circuit board, the ion wind generator is installed on the umbrella handle, and the ion wind generator is used to generate a second air flow after being powered on. The flow directions of the first air flow and the second air flow are the same.

[0005] The sunshade umbrella according to an embodiment of the utility model has at least the following beneficial effects: the ion wind generator generates positive and negative ions and utilizes the electric field force to make the positive ions and negative ions in the ion cloud move relatively, thereby generating a second air flow. The flow direction of the second air flow is the same as that of the first air flow, and the two air flows together improve the overall wind force.

[0006] According to some embodiments of the present utility model, the sunshade umbrella further includes a housing and a semiconductor refrigerator. There is an air duct inside the housing, and a first air flow and a second air flow flow through the air duct. The semiconductor refrigerator is electrically connected to the circuit board. The semiconductor refrigerator includes a refrigerating end and a heating end. The refrigerating end is inside the air duct, and the heating end is outside the air duct. When an electric current passes through a semiconductor material, a temperature difference will be generated at both ends of the material, that is, one end absorbs heat (the refrigerating end), and the other end releases heat (the heating end). This is because when charged carriers migrate under the action of an electric field force, they will collide with the lattice and exchange energy, resulting in a redistribution of heat inside the material. The refrigerating end absorbs heat and conducts it to the external environment, thereby achieving a refrigerating effect. Therefore, the semiconductor refrigerator is provided and the refrigerating end is arranged inside the air duct to reduce the temperature of the blown air flow and improve the user experience.

[0007] According to some embodiments of the present utility model, a heat exchange plate is arranged at the refrigerating end, and / or a heat exchange plate is arranged at the heating end. The heat exchange plate includes a plurality of heat exchange fins arranged at intervals. Arranging the heat exchange plate at the refrigerating end can improve the heat exchange efficiency between the refrigerating end and the air. The plurality of heat exchange fins arranged at intervals can further increase the heat exchange area with the air, so that the low temperature can quickly diffuse into the first air flow to improve the refrigerating effect. And arranging a heat exchange plate with a plurality of heat exchange fins at the heating end is to improve the heat exchange efficiency between the heating end and the air, quickly dissipate the heat generated by the semiconductor refrigerator, prevent the device from overheating, and improve the service life.

[0008] According to some embodiments of the present utility model, the ion wind generator is installed inside the housing and located on the inner wall surface of the air duct. In this way, the second air flow generated by the ion wind generator 501 can better flow into the air duct and be blown out.

[0009] According to some embodiments of the present utility model, the umbrella handle passes through the fan. The sunshade umbrella further includes a housing. The fan is arranged inside the housing. The housing includes an air inlet and an air outlet. The air inlet and the air outlet are arranged on the outer surfaces of different sides of the housing. Such a design allows the user to align the air outlet with himself while avoiding the air inlet during use, and arranging them on different sides can also reduce the influence of the air flow between the air outlet and the air inlet.

[0010] According to some embodiments of the present utility model, the sunshade umbrella further includes a grip. The housing is installed above the grip. The grip can make it more convenient for the user to hold the sunshade umbrella. The housing is installed above the grip because when holding the sunshade umbrella, the grip is generally at the same level as the user's torso. At this time, the air generated by the fan and the ion wind generator inside the housing can be well blown to the user's torso position, achieving a cooling effect.

[0011] According to some embodiments of the present utility model, the sunshade umbrella further includes a positioning module, which is electrically connected to the circuit board and is used to determine the position of the sunshade umbrella. In this way, when the user loses the sunshade umbrella, the position of the sunshade umbrella can be found through the positioning module, improving the anti-loss performance of the sunshade umbrella.

[0012] According to some embodiments of the present utility model, the material of the solar power generation film is a perovskite flexible film. When sunlight shines, the perovskite layer generates holes and electrons, which are absorbed by the point electrodes after passing through the hole transport layer and the electron transport layer respectively, and finally form electric energy. The perovskite material has a wide absorption spectrum and can absorb light with a wider wavelength range. Under weak light conditions on cloudy days, it can not only absorb short-wavelength light but also maintain a relatively stable state of energy conversion efficiency. Therefore, it can maintain a high power generation efficiency under various lighting conditions.

[0013] According to some embodiments of the present utility model, the sunshade umbrella further includes a storage battery, which is electrically connected to the circuit board and is used to store the electricity generated by the solar power generation film and supply power to the sunshade umbrella. The setting of the storage battery can store the electricity generated by the solar power generation film, improving the utilization rate of energy. It can also be used as a backup energy source to charge the electronic devices in the sunshade umbrella when the solar power generation film cannot generate electricity.

[0014] According to some embodiments of the present utility model, the sunshade umbrella further includes a charging module, which is electrically connected to the circuit board and is used to charge an external device. In this way, the sunshade umbrella can also charge portable electronic devices such as the user's mobile phone, improving the functional diversity of the sunshade umbrella and the utilization rate of the electricity generated by the solar power generation film.

Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0028] Referring to Figures 1 to 5 , according to an embodiment of the present utility model, the sunshade 100 includes a handle 101, a circuit board 102, a canopy 103, a solar power generation film 104, a fan 201, and an ion wind generator 501. The handle 101 is a hollow structure, the circuit board 102 is installed inside the handle 101, the canopy 103 is connected to the handle 101, the solar power generation film 104 is installed on the outer surface of the canopy 103, the solar power generation film 104 is electrically connected to the circuit board 102, and the solar power generation film 104 is used to supply power to the sunshade 100. The fan 201 is electrically connected to the circuit board 102, the fan 201 is installed on the handle 101, and the fan 201 is used to rotate to generate a first air flow. The ion wind generator 501 is electrically connected to the circuit board 102, the ion wind generator 501 is installed on the handle 101, and the ion wind generator 501 is used to generate a second air flow after being powered on. The flow directions of the first air flow and the second air flow are the same. The ion wind generator 501 generates positive and negative ions and utilizes the electric field force to make the positive ions and negative ions in the ion cloud move relatively, thereby generating the second air flow. The flow direction of the second air flow is the same as that of the first air flow, and the two air flows together enhance the overall wind force.

[0029] As Figure 2 , Figure 3 and Figure 5 shown, in some embodiments of the present utility model, the ion wind generator 501 is arranged above the fan 201 and between the air inlet 301 and the air outlet 202. The second air flow generated by the ion wind generator 501 and the first air flow generated by the rotation of the fan 201 are blown out from the air outlet 202 in a swirling shape to jointly enhance the wind force, providing a better user experience.

[0030] The ion wind generator 501 generates a high-intensity electric field. When low-pressure gas passes through this electric field, some molecules in the gas will be ionized under the action of the electric field, generating positively charged ions and negatively charged free electrons. These charged particles move towards the nozzle direction at a relatively high speed under the push of the electric field force and finally spray out from the nozzle, forming a second air flow called "ion wind". The ion wind generated by the ion wind generator 501 can also effectively neutralize the static electricity on the surface of the object and prevent the interference caused by static electricity. Secondly, the ion wind can remove dust in the air. Since the charged particles have an attracting effect on light and small dust, the ion wind can capture and remove dust particles in the air during the movement process, improving the purity of the air flow blown by the user. Moreover, the ion wind generator 501 has low energy consumption, simple operation and maintenance, and is safe and harmless. When the ion wind generator 501 operates, the noise is extremely low and no additional heat is generated.

[0031] It should be noted that in some embodiments of the present utility model, the positions on the umbrella surface 103 that are not covered with the solar power generation film 104 are also coated with materials such as black glue (high-density polyester fiber) or silver glue (high-density nylon coated with a silver layer), etc., to improve the ability of the umbrella surface 103 to absorb and reflect ultraviolet rays and enhance the sun protection performance of the sunshade 100.

[0032] It should be noted that in some embodiments of the present utility model, the structure of the solar power generation film 104 cooperating with the ion wind generator 501 and the fan 201 is applied not only in Figure 1 and Figure 4 the field of the handheld umbrella shown, but also in the fields of large commercial sunshades 100, sunshade canopies or tents, etc.

[0033] Refer to Figure 2 and Figure 3 , in some embodiments of the present utility model, the sunshade 100 further includes a housing 306 and a thermoelectric cooler 203. There is an air duct in the housing 306, and the first air flow and the second air flow flow through the air duct. The thermoelectric cooler 203 is electrically connected to the circuit board 102. The thermoelectric cooler 203 includes a cooling end 204 and a heating end 205. The cooling end 204 is in the air duct, and the heating end 205 is outside the air duct. The thermoelectric cooler 203 mainly utilizes the Peltier effect. Specifically, when an electric current passes through a semiconductor material, a temperature difference will be generated at both ends of the material, that is, one end absorbs heat (cooling end 204), and the other end releases heat (heating end 205). This is because when the charged carriers migrate under the action of the electric field force, they will collide with the lattice and exchange energy, resulting in the redistribution of heat inside the material. The cooling end 204 absorbs heat, and the heating end 205 conducts the heat to the external environment, thereby achieving the refrigeration effect. Therefore, the thermoelectric cooler 203 is provided and the cooling end 204 is arranged in the air duct to reduce the temperature of the blown air flow and improve the user experience.

[0034] Reference Figure 2 In some embodiments of the present utility model, a heat exchange plate 206 is provided at the refrigeration end 204, and / or a heat exchange plate 206 is provided at the heating end 205. The heat exchange plate 206 includes a plurality of heat exchange fins 207 arranged at intervals. The heat exchange plate 206 provided at the refrigeration end 204 can improve the heat exchange efficiency between the refrigeration end 204 and the air. The plurality of heat exchange fins 207 arranged at intervals can further increase the heat exchange area with the air, so that the low temperature can be quickly diffused into the first air flow to improve the refrigeration effect. The heat exchange plate 206 with a plurality of heat exchange fins 207 provided at the heating end 205 is to improve the heat exchange efficiency between the heating end 205 and the air, quickly dissipate the heat generated by the thermoelectric cooler 203, prevent the device from overheating, and improve the service life.

[0035] It should be noted that, in some embodiments of the present utility model, a heat dissipation module is separately provided for each electronic device in the sunshade 100 to prevent each device from being damaged due to overheating.

[0036] Reference Figure 3 and Figure 5 In some embodiments of the present utility model, the ion wind generator 501 is installed inside the housing 306 and located on the inner wall surface of the air duct. In this way, the second air flow generated by the ion wind generator 501 can better converge into the air duct and be blown out.

[0037] It should be noted that, reference Figure 5 In some embodiments of the present utility model, the ion wind generator 501 is arranged upstream of the fan 201. The second air flow generated by the ion wind generator 501 converges into the first air flow generated by the fan from top to bottom and is blown out together, improving the user experience. In some embodiments of the present utility model, the ion wind generator can also be arranged downstream of the fan 201, which can achieve the same technical effect. The upstream and downstream in this article mean that the fan rotates to generate wind power, the starting end of the wind power is the upstream, and the direction of the wind power is the downstream. Reference Figure 2 、 Figure 3 and Figure 5 In some embodiments of the present utility model, the flow direction of the air is specifically from the air inlet 301, rotating in a vortex shape from top to bottom and finally blowing out from the air outlet 202.

[0038] It should be noted that, reference Figure 3, in some embodiments of the present utility model, the sunshade 100 further includes a controller 302. The controller 302 is electrically connected to the circuit board 102. The controller 302 includes a plurality of buttons 303, and at least three buttons 303 are used to control the on and off of the fan 201, the ion wind generator 501, and the semiconductor cooler 203. The setting of the controller 302 can perform more refined control on various devices in the sunshade 100. The use or stop of the fan 201, the ion wind generator 501, and the semiconductor cooler 203 can be selected through the buttons 303, improving the user experience.

[0039] It should be noted that, in some embodiments of the present utility model, a plurality of buttons 303 can also be provided to control functions such as the opening and closing of the umbrella surface 103 and the rotation speed of the fan 201.

[0040] Reference Figure 2 、 Figure 3 and Figure 5 , in some embodiments of the present utility model, the umbrella handle 101 passes through the fan 201. The sunshade 100 further includes a housing 306. The fan 201 is disposed inside the housing 306. The housing 306 includes an air inlet 301 and an air outlet 202. The air inlet 301 and the air outlet 202 are disposed on the outer surfaces of different sides of the housing 306. Such a design allows the user to align the air outlet 202 with himself while avoiding the air inlet 301 during use, and the arrangement on different sides can also reduce the influence of the air flow between the air outlet 202 and the air inlet 301.

[0041] It should be noted that, reference Figure 3 , in some embodiments of the present utility model, the orientations of the air inlet 301 and the air outlet 202 are perpendicular to the central axis of the umbrella handle 101. Such a design effectively improves the efficiency of air circulation. When the umbrella handle 101 is in the vertical position, the air inlet 301 can quickly capture the surrounding air, and the air outlet 202 can blow the processed air at the best angle and speed, forming a stable air flow. This design enables the air flow to quickly and evenly cover the places where the user needs, improving the use effect of the product. Secondly, the vertical design also makes the air inlet 301 and the air outlet 202 have better rain and dust protection performance. The vertical air inlet and air outlet can effectively block the entry of rain or dust, keeping the interior of the product clean and dry.

[0042] It should be noted that, reference Figure 3 , in some embodiments of the present utility model, the height of the air inlet 301 in the horizontal position is higher than the position of the air outlet 202. In this way, it is easier to form a swirling air flow, the air flow is more stable, and the use effect is improved.

[0043] Reference Figure 3, in some embodiments of the present utility model, the sunshade 100 further includes a grip 105, and the housing 306 is installed above the grip 105. The grip 105 can make it more convenient for the user to hold the sunshade 100, and the housing 306 is installed above the grip 105 because when holding the sunshade 100, the grip 105 is generally flush with the user's torso position. At this time, the wind generated by the fan 201 and the ion wind generator 501 in the housing 306 can be well blown to the user's torso position, achieving a cooling effect.

[0044] In some embodiments of the present utility model, the sunshade 100 further includes a positioning module, and the positioning module is electrically connected to the circuit board 102. The positioning module is used to determine the position of the sunshade 100. In this way, when the user loses the sunshade 100, the user can find the position of the sunshade 100 through the positioning module, improving the anti-loss performance of the sunshade 100. It should be noted that in some embodiments of the present utility model, software can be set to be bound to the controller 302 in the sunshade 100, and the controller 302 is electrically connected to the positioning module and the battery 304 mentioned below. The user can view the current position and remaining power of the sunshade 100 through the software. In some embodiments of the present utility model, the program can also observe the current battery state, improve the energy storage and management efficiency, and meet the requirements of sustainable and efficient products.

[0045] In some embodiments of the present utility model, the material of the solar power generation film 104 is a perovskite flexible thin film. When sunlight shines, the perovskite layer generates holes and electrons, which are respectively absorbed by the point electrodes after passing through the hole transport layer and the electron transport layer, and finally form electric energy. The perovskite material has a wide absorption spectrum and can absorb light with a wider wavelength range. Under weak light conditions on cloudy days, it can not only absorb short-wavelength light but also maintain a relatively stable energy conversion efficiency. Therefore, it can maintain a high power generation efficiency under various light conditions.

[0046] It should be noted that in some embodiments of the present utility model, in addition to using single-junction perovskite solar cells for the solar power generation film 104, other thin-film batteries can also be used to form a tandem battery with the perovskite solar cell, such as flexible organic solar cells, flexible CIGS (copper indium gallium selenide), etc., or form an all-perovskite tandem solar cell with perovskites of different bandgaps.

[0047] Reference Figure 3, in some embodiments of the present utility model, the sunshade 100 further includes a storage battery 304. The storage battery 304 is electrically connected to the circuit board 102. The storage battery 304 is used to store the electricity generated by the solar power generation film 104 and supply power to the sunshade 100. The setting of the storage battery 304 can store the electricity generated by the solar power generation film 104, improve the utilization rate of energy, and can also be used as a backup energy source to charge the electronic devices in the sunshade 100 when the solar power generation film 104 cannot generate electricity.

[0048] It should be noted that, in some embodiments of the present utility model, the storage battery 304 preferably uses a lithium battery. The lithium battery has a high energy density, which means that under the same volume or mass, the lithium battery can store more energy. Therefore, it is suitable for the energy storage of the portable sunshade 100. Moreover, the lithium battery has a fast charging speed, which improves the use efficiency. And the lithium battery does not contain heavy metal pollutants such as lead and mercury, has little impact on the environment, and has the advantages of high energy density, low self-discharge rate, long cycle life, fast charging and environmental protection. Nickel-metal hydride batteries (NiMH), nickel-cadmium batteries (NiCd), lead-acid batteries, etc. can also be used instead.

[0049] It should be noted that, in some embodiments of the present utility model, the controller 302 can control the flow of electric energy. Specifically, it includes the following situations: when the power consumption devices such as the fan 201, the semiconductor cooler 203, and the ion wind generator 501 are greater than the power generation of the solar power generation film 104, the solar power generation film 104 and the storage battery 304 supply power to the power consumption devices at the same time. When the energy required by the power consumption devices is less than the current power generation, a part of the electric energy generated by the solar power generation film 104 flows to the power consumption devices for power supply, and a part flows to the lithium battery for storage, so as to realize the effective utilization of electric energy.

[0050] It should be noted that, in some embodiments of the present utility model, the sunshade 100 can also add electronic devices such as lighting devices, which can be adjusted according to actual use requirements.
