Description

Technical Field

[0001] The invention relates to the technical field of umbrellas, in particular to an umbrella that changes color according to weather changes. Background Art

[0002] An umbrella is a tool that can provide a cool environment or shelter from rain, snow, sunlight, etc. It can be said that an umbrella is closely related to people's lives.

[0003] The existing umbrellas have a relatively simple appearance and can only be used for sunshade or rainproof effect, and are not novel. In addition, conventional umbrellas are all solid colors or have patterns. There are also many umbrellas that can change color in the prior art. For example, Chinese patent No. CN209436454U discloses a color-changing umbrella, including an umbrella body, which includes an umbrella cloth, an umbrella frame, a support rod and a handle. The umbrella cloth is evenly divided into a plurality of fan-shaped areas, and the umbrella cloth is also divided into a plurality of circular areas. The fan-shaped areas and the circular areas divide the umbrella cloth into a plurality of small pieces, and each small piece on the umbrella cloth is coated with a temperature-sensitive or light-sensitive color-changing material, a humidity-sensitive color-changing material and a night-luminous material. The umbrella cloth is divided into several areas, and the divided areas are integer multiples of 3. The three materials are evenly distributed on the umbrella cloth. The different characteristics of the three materials are used to make the umbrella change different colors according to different air temperatures or light intensities. At the same time, it changes to the color we want when it encounters water on rainy days, changing our different moods on sunny and rainy days. It automatically glows in the dark, which can not only illuminate people in the dark, but also alert other pedestrians and vehicles on the road.

[0004] This patent changes the color of the umbrella by cooperating with photosensitive color-changing materials, moisture-sensitive color-changing materials and night-luminous materials. However, the color-changing materials are generally not sensitive enough and cannot respond to weather changes in time. If sensitive color-changing materials are set and the umbrella is placed indoors, due to the temperature difference between indoor and outdoor and the difference in optical fiber, the color-changing materials cannot truly reflect the overall weather conditions. For this reason, we propose an umbrella that changes color according to weather changes to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide an umbrella that changes color according to weather changes, so as to solve the problems raised in the above-mentioned background technology.

A cylindrical lithium battery 11 is fixedly connected to the inner wall of the lower section of the telescopic support rod 3, and a charging socket 12 fixedly connected to the bottom of the telescopic support rod 3 is provided at the bottom of the cylindrical lithium battery 11; a temperature and humidity sensor 23 fixedly embedded in the top of the umbrella top 2 monitors the ambient temperature and humidity, and transmits the monitored values ​​to the microprocessor 10 according to the changes in the ambient temperature and humidity, and the cylindrical lithium battery 11 is powered. The microprocessor 10 processes the values ​​and controls the colorful LED light strip 8 to emit light of different colors. The light emitted by the colorful LED light strip 8 is concentrated and guided by the connected light guide ring 9 and then transmitted to the light guide strip 101 connected to the other end of the light guide hole through the opened light transmission hole. The light guide strip 101 is a soft and transparent light guide strip, which guides the colorful light emitted by the colorful LED light strip 8 to be dispersed to the surface of the umbrella cloth 1, thereby realizing the color change of the umbrella cloth 1 according to different weather conditions.

[0027] The fixed support rod 5 is slidably sleeved outside the telescopic support rod 3, the bottom of the fixed support rod 5 is connected to the handle 6 through a threaded structure, the top inner wall of the handle 6 is fixedly connected to the charging seat 13, and the bottom end of the handle 6 is provided with a charging port 14. The telescopic support rod 3 is extended and then buckled into the circular hole of the fixed support rod 5 through the elastic buckle 4 to fix the length position of the telescopic support rod 3, and the umbrella cloth 1 is unfolded and used by unfolding the umbrella ribs slidably sleeved outside the telescopic support rod 3.

[0028] Example 2

[0029] Reference Figure 1-5 , which is the second embodiment of the present invention, and is based on the previous embodiment. Specifically, the outer edge of the umbrella cloth 1 is fixedly sewn with a lock edge 7, and the lock edge 7 is in a U-shaped structure and wrapped around the outer edge of the umbrella cloth 1. The material of the lock edge 7 close to the umbrella cloth 1 is a reflective cloth, and the outer material of the side away from the umbrella cloth 1 is a shading cloth. The setting of the lock edge 7 performs closed reflection on the end of the light guide bar 101, preventing the light guided by the light guide bar 101 to the colorful LED light strip 8 from radiating to the outside from the end of the light guide bar 101, and ensuring the concentration of colorful light.

[0030] Specifically, a plurality of light-transmitting holes are provided in the light-guiding ring 9, and one end of the light-transmitting hole is connected to the light source of the multi-color LED light strip 8, so as to centrally guide the colored light emitted by the multi-color LED light strip 8 to avoid excessive dispersion of the light source. The other end is fixedly connected to the light-guiding strip 101, and the light-guiding strip 101 is arranged in a ring array with the center of the umbrella cloth 1 as the array point. The plurality of light-guiding strips 101 are arranged in an array, so as to ensure that the guided colored light is evenly and widely distributed.

[0031] Specifically, the upper arc-shaped outer wall of the umbrella top 2 is fixedly connected with a water retaining ring 21, and the water retaining ring 21 is located above the umbrella cloth 1. When the umbrella is in use, the water retaining ring 21 contacts the outer surface of the umbrella cloth 1 after the umbrella cloth 1 is fully unfolded, thereby sealing and shielding the connection between the umbrella cloth 1 and the umbrella top 2, preventing rainwater from entering the cavity 22 through the light-transmitting hole of the light guide ring 9, thereby ensuring the sealing inside the telescopic support rod 3.

[0032] Specifically, the telescopic support rod 3 is limited by the elastic buckle 4 in cooperation with the circular hole provided on the fixed support rod 5, thereby ensuring that the length and position of the telescopic support rod 3 are fixed.

[0033] Specifically, the charging port 14 is a Type-C port. The setting of the Type-C port is convenient for quickly charging the cylindrical lithium battery 11. At the same time, the Type-C interface has a wide range of uses and it is easy to find a corresponding charging adapter. The microprocessor 10 has built-in Bluetooth and wireless transceiver modules, and can connect to smart devices (such as mobile phones, computers, etc.) via Bluetooth or wireless networks. The microprocessor 10 interacts with the weather software in the smart device to obtain the data of the weather software in real time, and then cooperates with the weather software data of the smart device to control the color change of the colorful LED light strip 8, so that the umbrella can respond to the weather more sensitively and accurately.

[0034] Specifically, the umbrella cloth 1 includes a waterproof film 102 arranged at the outermost layer, and a waterproof coating 103 is connected to one side of the waterproof film 102. Both the waterproof film 102 and the waterproof coating 103 are made of transparent materials. The transparent waterproof film 102 cooperates with the transparent waterproof coating 103 to effectively block rain and prevent rainwater from seeping into the inside of the umbrella cloth 1 on rainy days. A transparent light-scattering layer 104 is connected to one side of the waterproof coating 103. The transparent light-scattering layer 104 scatters the light guided by the light guide strip 101 to ensure the uniformity of the light distribution. A plurality of light guide strips 101 are connected to one side of the transparent light-scattering layer 104. Resin fillers 105 are filled between the light guide strips 101. The transparent resin fillers 105 fix the position of the light guide strips 101. In order to prevent the light guide strip 101 from being damaged, the transparent light scattering layer 104 and the reflective layer 106 on both sides of the light guide strip 101 are also bonded and fixed. The side of the light guide strip 101 away from the transparent light scattering layer 104 is connected with the reflective layer 106. The reflective layer 106 reflects the light guided by the light guide strip 101, thereby increasing the penetration of the light. One side of the reflective layer 106 is connected with an anti-ultraviolet layer 107. One side of the anti-ultraviolet layer 107 is connected with the innermost base fabric layer 108. The anti-ultraviolet layer 107 isolates ultraviolet rays.

[0035] Example 3

[0036] Reference Figure 1-5, which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. When in use, the telescopic support rod 3 is extended, and then the elastic buckle 4 is buckled into the circular hole opened in the fixed support rod 5 to fix the length position of the telescopic support rod 3. The umbrella cloth 1 is unfolded and used by unfolding the umbrella ribs that are slidably sleeved outside the telescopic support rod 3; the temperature and humidity sensor 23 fixedly embedded in the top of the umbrella top 2 monitors the ambient temperature and humidity, and transmits the monitored values ​​to the microprocessor 10 according to the changes in the ambient temperature and humidity. The cylindrical lithium battery 11 is powered, and the microprocessor 10 processes the values ​​and controls the colorful LED light strip 8 to emit light of different colors. The light emitted by the colorful LED light strip 8 is concentrated and guided by the connected light guide ring 9 and then transmitted to the light guide strip 101 connected to the other end of the light guide hole through the opened light transmission hole. The light guide strip 101 is a soft and transparent light guide strip, thereby controlling the colorful light emitted by the colorful LED light strip 8. The light is guided and dispersed to the surface of the umbrella cloth 1. The outer layer of the light guide strip 101 is connected to a transparent light diffusion layer 104. The transparent light diffusion layer 104 diffuses the light, and the reflective layer 106 reflects the diffused light, so that the surface of the umbrella cloth 1 can be uniformly discolored. When used on rainy days, the transparent waterproof film 102 on the outer layer of the umbrella cloth 1 cooperates with the transparent waterproof coating 103 to effectively block rain. At the same time, the water retaining ring 21 of the umbrella top 2 contacts the outer surface of the umbrella cloth 1 after the umbrella cloth 1 is fully unfolded, thereby sealing and shielding the connection between the umbrella cloth 1 and the umbrella top 2 to prevent rainwater from entering the cavity 22 through the light transmission hole of the light guide ring 9; when the cylindrical lithium battery 11 needs to be charged, the telescopic support rod 3 is completely retracted into the fixed support rod 5. At this time, the charging socket 12 fixedly connected to the bottom end of the telescopic support rod 3 is connected to the charging seat 13, and the charging seat 13 is electrically connected to the charging port 14. After the charging adapter is connected to the charging port 14, the cylindrical lithium battery 11 is charged.
