The present disclosure provides an ultraviolet-ray detecting device, a smart apparatus and a fabricating method, which enables the user to monitor the intensities of ultraviolet irradiations in everyday life, to facilitate the user to timely prevent continuous irradiation under an ultraviolet irradiation of a high intensity.
The present disclosure provides an ultraviolet-ray detecting device.
As shown in
Certainly, the covers having different ultraviolet-ray blocking capacities may also be formed not by using the ultraviolet-ray blocking films having different quantities of stacked layers. For example, the covers may also be formed by using ultraviolet-ray blocking films that have the same thickness but have different ultraviolet-ray blocking capacities.
In brief, for an ultraviolet ray, the cover has a certain light transmittance, to enable the ultraviolet ray of a certain intensity to pass through the cover, and also has a certain opacity. In other words, different covers have different effects of blocking or obstructing an ultraviolet ray. When the covers are formed by using the same material, that may be realized by using covers of different thicknesses or covering layers of different quantities of layers. If the employed covers have higher thicknesses or higher quantities of layers, the effect of the covers of blocking or obstructing an ultraviolet ray is more obvious.
A requirement on the cover is that it is transmittable to the color of the visible light generated by the ultraviolet photochromism, whereby the change in color caused by the ultraviolet photochromism can be observed through the cover. For example, the cover is transparent or translucent to visible light. Another requirement on the cover is that its position is set so that it can block the ultraviolet ray irradiating from the environment to the ultraviolet-photochromic marker.
The device may further be provided with, if appropriate, a flat layer 6 and so on, which is not particularly limited in the present disclosure. Such a flat layer is merely required to have substantially no influence on the transmission of visible light and ultraviolet light.
An ultraviolet-photochromic ink that has been completely prepared may be sucked by using a fountain pen or a brush pen, and the ultraviolet-photochromic markers 3 may be formed by using the ultraviolet-photochromic ink in each of the identification regions 2. The ultraviolet-photochromic ink on the substrate may be drawn into patterns of an easily identifiable shape such as five-pointed stars and circles by hand-drawn marking, to facilitate the user to observe.
In the ultraviolet-ray detecting device according to the present disclosure, the ultraviolet-photochromic marker 3 will discolor under an ultraviolet irradiation. As the intensity of the ultraviolet irradiation increases, the color of the ultraviolet-photochromic marker 3 can gradually darken. In other words, the darkness of the color of the ultraviolet-photochromic marker 3 is related to the intensity of the ultraviolet irradiating on the marker, and may be used to characterize different ultraviolet intensities.
As different from the conventional solution that a single one ultraviolet-photochromic marker is employed and the discoloration result is compared with a pre-prepared colorimetric card to measure the ultraviolet intensity, the device according to the present disclosure realizes different actual irradiation intensities by providing the different covers in the different identification regions, and realizes the measurement on the ultraviolet intensity by comparing the colors of the different identification regions. The device according to the present disclosure can avoid the comparison with the pre-prepared colorimetric card, which comparison is frequently difficult for the user. By properly controlling the parameters of the covers and the markers, the device according to the present disclosure can enable the identification regions to have color development under different environmental-ultraviolet threshold intensities, and, by arranging the identification regions in order, can enable the user to easily determine the ultraviolet intensity of the current environment.
Typically, in each of the identification regions, under the irradiation of ultraviolet lights of the same intensity, the same discoloration results are obtained. For example, ultraviolet-photochromic markers of the same thickness and the same material may be used, but their patterns may be different. Accordingly, under the irradiation of the same ambient light, the difference between the discoloration results of the ultraviolet-photochromic markers of the different identification regions totally depends on the covers. When the identification regions 2 of the ultraviolet-photochromic markers 3 are covered by the covers, if one of them is covered by a cover having a higher capacity of blocking an ultraviolet ray, for example an ultraviolet-ray blocking film having a higher quantity of covering layers or a higher thickness, the effect of blocking or obstructing an ultraviolet ray is higher, and the corresponding identification region 2 has more difficulty in receiving the ultraviolet irradiation. As the intensities of the ultraviolet irradiation received by the identification regions 2 are increasingly lower, the colors of the ultraviolet-photochromic ink on the identification regions 2 are increasingly lighter, and even cannot easily discolor. If one of them is covered by a cover having a lower capacity of blocking an ultraviolet ray, for example an ultraviolet-ray blocking film having a lower quantity of covering layers or a lower thickness, the effect of blocking or obstructing an ultraviolet ray is weaker, the corresponding identification region 2 has lower difficulty in receiving the ultraviolet irradiation, and the ultraviolet-photochromic ink on the identification region 2 can more easily discolor, and have a darker color.
In some embodiments, the covers comprise ultraviolet-ray blocking films having different quantities of stacked layers, and the identification regions 2 on the substrate 1 may be arranged in a sequence in which the quantities of the stacked layers of the covering ultraviolet-ray blocking films are progressively increased or progressively reduced. In other words, the plurality of identification regions are arranged so that the quantities of the stacked layers of the ultraviolet-ray blocking films in the identification regions are progressively increased or progressively reduced in an arranging sequence. The different identification regions 2 arranged in a sequence are covered by the ultraviolet-ray blocking films whose quantities of the layers are progressively increased or progressively reduced, so that the darknesses of the colors of the ultraviolet-photochromic markers 3 are changed in a certain sequence. That facilitates the user to determine the irradiation intensity of an ultraviolet ray by observing the discoloration in a sequence of the identification regions 2. In addition, the quantities of the stacked layers of the ultraviolet-ray blocking films in the different identification regions 2 may be set according to requirements by the measurement by the user, to increase the adaptability of the product. For example, as shown in
In some embodiments, the ultraviolet-ray blocking films are marked with ultraviolet-resistance degrees based on the quantities of the stacked layers. The identification regions 2 are marked with different ultraviolet-resistance degrees corresponding to the quantities of the stacked layers of the ultraviolet-ray blocking films, whereby the user, in practical usage, can identify the irradiation intensity of an ultraviolet ray according to the quantities of the layers of the ultraviolet-ray blocking films in the different identification regions 2, and in turn acquire the ultraviolet-resistance degree, so as to prepare the corresponding protection.
For example,
The present disclosure, by using the characteristic of the ultraviolet-photochromic markers 3 of the ultraviolet-ray detecting device, i.e., the characteristic of the ultraviolet-photochromic markers 3 that the color is darkened under an ultraviolet irradiation of a high intensity, enables the user to monitor in real time the intensities of ultraviolet irradiations in everyday life, to acquire the intensity of the ultraviolet irradiation of his current environment at any time and at any place, and, when the intensity of the ultraviolet irradiation is too high, emit a protection alarming timely by using the ultraviolet-ray detecting device. Moreover, the component compositions of the ultraviolet-photochromic markers 3 or the quantities of the stacked layers of the ultraviolet-ray blocking films may be regulated, to realize customized designs for different people.
In some embodiments, the ultraviolet-photochromic marker is formed by an ultraviolet-photochromic ink, wherein the ultraviolet-photochromic ink is a mixture of an aqueous solution of an ultraviolet-photochromic polyoxometallate and an aqueous solution of an electron donor, in which the electron donor reduces the ultraviolet-photochromic polyoxometallate stepwisely under a certain condition. The combination of the ultraviolet-photochromic polyoxometallate and the electron donor is known in the art. Such a combination is particularly suitable for the solutions of the present disclosure, because it can easily form the desired ultraviolet-photochromic marker, and its ultraviolet-photochromic property is easily controllable by the concentration relation between the two components. The ultraviolet-photochromic polyoxometallate, under the condition of the electron donor and the ultraviolet irradiation, can realize multi-step reduction, thereby obtaining a series of intermediate products of multiple valence states; in other words, the ultraviolet-photochromic polyoxometallate emerges directly with different colors, whereby the ultraviolet-photochromic marker 3 has the characteristic that the color is darkened under an ultraviolet irradiation of a high intensity, and, thus, can, under different intensities of ultraviolet irradiations, display the colors of its different intermediate products to the user. The ultraviolet-photochromic ink itself may serve as the ultraviolet-photochromic marker. Alternatively, the ultraviolet-photochromic ink may also form the ultraviolet-photochromic marker after it has been semi-dried or dried. Preferably, the marker formed after the ink has been dried is employed, which facilitates the subsequent covering by the cover.
The ultraviolet-photochromic ink may be prepared at any time for the monitoring of ultraviolet irradiations. If the ultraviolet-photochromic ink is not to be used immediately after it is prepared, considering the disadvantage of the ultraviolet-photochromic ink of easy deterioration when exposed to sunlight, after the preparation of the ultraviolet-photochromic ink and before the usage, it may be stored with protection from light, to effectively protect the effectiveness and the durability of the ultraviolet-photochromic ink. For example, the prepared ultraviolet-photochromic ink is protected by using nitrogen, which is an inert gas.
In some embodiments, a ratio of molar concentrations of the aqueous solution of the ultraviolet-photochromic polyoxometallate to the aqueous solution of the electron donor is in a range of 1:10 to 1:120. Preferably, they are formulated with a concentration ratio of 1:60. For example, in formulation, certain volumes of an aqueous solution of the ultraviolet-photochromic polyoxometallate of 10 millimoles per liter and of an aqueous solution of the electron donor of 600 millimoles per liter are individually formulated. When they are required to be used, the aqueous solution of the ultraviolet-photochromic polyoxometallate of 10 millimoles per liter and the aqueous solution of the electron donor of 600 millimoles per liter are mixed with equal volumes, and an ultraviolet-photochromic ink containing 5 millimoles per liter of the ultraviolet-photochromic polyoxometallate and 300 millimoles per liter of the electron donor can be obtained. That ratio is a usual ratio of the concentration ratio of the aqueous solutions of the ultraviolet-photochromic polyoxometallate and of the electron donor; however, because different people have different degrees of tolerance to an ultraviolet ray, personalized customization based on different conditions of people is required. For example, for users such as children and the aged, they are people who are extremely sensitive to an ultraviolet ray, and they have a low degree of tolerance to an ultraviolet ray of a certain intensity. In addition, female users, considering the demand on aesthetic appeal, have a degree of tolerance to an ultraviolet ray lower than that of male users. Therefore, personalized customization for users may be performed by taking into consideration the factors such as the physiques and the ages of different users, in the following two manners. One of the manners is to, according to the difference in the physiques of the users, regulate the concentration ratio of the aqueous solution of the ultraviolet-photochromic polyoxometallate to the aqueous solution of the electron donor. For example, the concentration of the electron donor is adjusted while the concentration of the ultraviolet-photochromic polyoxometallate is maintained constant. When the users are the people who are sensitive to an ultraviolet ray such as children, the aged and women, the concentration of the electron donor may be increased properly, whereby, under the same ultraviolet irradiation, the speed of the reduction of the ultraviolet-photochromic polyoxometallate is increased, so as to accelerate the changing of the color of the ultraviolet-photochromic ink, to alert, under a low ultraviolet intensity, the people sensitive to an ultraviolet ray to make the protection. The other manner is to, according to the difference in the physiques of the users, regulate the quantities of the stacked layers of the ultraviolet-ray blocking films. For example, when the covers are the ultraviolet-ray blocking films, the quantities of the stacked layers or the thickness of the ultraviolet-ray blocking films are regulated. When the users are the people who are sensitive to an ultraviolet ray such as children, the aged and women, the users are alerted, under a low ultraviolet intensity, by reducing the quantities of the stacked layers of the ultraviolet-ray blocking films or reducing the thicknesses of the ultraviolet-ray blocking films. For example, in the ultraviolet-ray detecting device used for children, as compared with the ultraviolet-ray detecting device used for adults, the ultraviolet-ray blocking films covering the same degrees of the marking regions have lower quantities of the layers or are thinner. For example, in a region of the same ultraviolet-resistance degree, the quantity of the layers of the ultraviolet-ray blocking film covering the ultraviolet-ray detecting device used for children may be 4 layers, while the quantity of the layers of the ultraviolet-ray blocking film covering the ultraviolet-ray detecting device used for adult men may be 6 layers. Accordingly, the ultraviolet-ray detecting device whose ultraviolet-ray blocking films have low quantities of stacked layers or low thicknesses can discolor under a low ultraviolet intensity to alert the user, to prevent further sunburn.
In some embodiments, the ultraviolet-photochromic polyoxometallate may be a phosphomolybdate, and the electron donor may be at least one of oxalic acid, glycolic acid and lactic acid. Phosphomolybdate is a representative ultraviolet-photochromic polyoxometallate, and it has stable properties of color changing and reduction. Phosphomolybdate, when reduced, can change from being colorless to a gradually darkened blue color. After the mixing between the aqueous solution of the phosphomolybdate and the aqueous solution of the electron donor, under irradiation of different ultraviolet intensities, all of the oxalic acid, the glycolic acid and the lactic acid can reduce the phosphomolybdate into different intermediate products under different ultraviolet sources within 30 minutes, whereby they can emerge with different darknesses of blue color.
In some embodiments, in order to facilitate the user to intuitively see the state of the discoloration of the ultraviolet-photochromic ink, all of the identification regions 2 are marked with the same or different markers. For example, the ultraviolet-photochromic markers may be of a shape of a five-pointed star, heart-shaped or of any other shapes, to facilitate the user to observe. By using the markers having a shape, the user can more clearly acquire the information on the intensity of the ultraviolet radiation. For example, the shapes of the markers are the same shape of a five-pointed star. Under the same ultraviolet irradiation, the states of the discoloration of the ultraviolet-photochromic markers 3 in the identification regions 2 are different, and therefore the five-pointed stars in the identification regions 2 display different colors, to indicate different degrees of the intensities of the ultraviolet irradiation. The different identification regions 2 corresponds to the different ultraviolet-resistance degrees, and the different ultraviolet-resistance degrees correspond to the quantities of the stacked layers of the ultraviolet-ray blocking films.
As an example, as shown in
The above embodiments of the present disclosure, by using the characteristic of the ultraviolet-photochromic markers of the ultraviolet-ray detecting device, i.e., the characteristic of the ultraviolet-photochromic markers that the color is darkened under an ultraviolet irradiation of a high intensity, enable the user to monitor in real time the intensities of ultraviolet irradiations in everyday life, to monitor at any time and at any place the intensity of the ultraviolet irradiation of the environment where he is located, and, when the intensity is too high, timely emit the protection alarming, and can realize customized designs for different people by regulating the component composition of the ultraviolet-photochromic ink or the thickness of the ultraviolet-ray blocking films.
The present disclosure provides a fabricating method of an ultraviolet-ray detecting device. As shown in
S101: preparing an ultraviolet-photochromic ink.
Regarding the step S101, the step of preparing the ultraviolet-photochromic ink comprises: providing certain volumes of an aqueous solution of an ultraviolet-photochromic polyoxometallate and an aqueous solution of an electron donor; and mixing the aqueous solution of the ultraviolet-photochromic polyoxometallate and the aqueous solution of the electron donor, whereby the electron donor reduces the ultraviolet-photochromic polyoxometallate stepwisely under a certain condition. The ultraviolet-photochromic polyoxometallate, under the conditions of the electron donor and the ultraviolet irradiation, can realize multi-step reduction, thereby obtaining a series of intermediate products of multiple valence states; in other words, the ultraviolet-photochromic polyoxometallate emerges directly with different colors, whereby the ultraviolet-photochromic ink has the characteristic that the color is darkened under an ultraviolet irradiation of a high intensity, and, thus, can, under different intensities of ultraviolet irradiations, display the colors of its different intermediate products to the user.
In some embodiments, the step of preparing the ultraviolet-photochromic ink further comprises: protecting the ultraviolet-photochromic ink that has been completely prepared from light and by using nitrogen sealing. The ultraviolet-photochromic ink may be prepared at any time for the monitoring of ultraviolet irradiations. If the ultraviolet-photochromic ink is not to be used immediately after it is prepared, considering the disadvantage of the ultraviolet-photochromic ink 3 of easy deterioration when exposed to sunlight, after the preparation of the ultraviolet-photochromic ink 3 and before the usage, it may be stored with protection from light, to effectively protect the effectiveness and the durability of the ultraviolet-photochromic ink. For example, the prepared ultraviolet-photochromic ink 3 is protected by using nitrogen, which is an inert gas.
In some embodiments, the ultraviolet-photochromic polyoxometallate is a phosphomolybdate, and the electron donor is at least one of oxalic acid, glycolic acid and lactic acid. Phosphomolybdate is a representative ultraviolet-photochromic polyoxometallate, and it has stable properties of color changing and reduction. Phosphomolybdate, when reduced, can change from being colorless to a gradually darkened blue color. In other words, after the mixing between the aqueous solution of the phosphomolybdate and the aqueous solution of the electron donor, under irradiation of different ultraviolet intensities, all of the oxalic acid, the glycolic acid and the lactic acid can reduce the phosphomolybdate into different intermediate products under different ultraviolet sources within 30 minutes, whereby they can emerge with different darknesses of blue color.
S102: delimiting a plurality of identification regions 2 on a substrate 1.
In this step, the identification regions 2 are sequentially arranged on the substrate 1. The shapes of the identification regions 2 may be rectangle, circle and another shape that can be displayed. That facilitates to provide the ultraviolet-photochromic markers 3 in each of the identification regions 2.
S103: spreading the ultraviolet-photochromic ink in each of the identification regions 2, to form the ultraviolet-photochromic markers 3.
In some embodiments, the step of delimiting the identification regions 2 on the substrate 1 that are sequentially arranged further comprises: marking each of the identification regions 2 with the same or different markers. The ultraviolet-photochromic markers may be of a shape of a five-pointed star, heart-shaped or of any other shapes, to facilitate the user to observe. By using the markers having a shape, the user can more clearly acquire the information on the intensity of the ultraviolet radiation. For example, the shapes of the markers are the same shape of a five-pointed star. Under the same ultraviolet irradiation, the states of the discoloration of the ultraviolet-photochromic markers 3 in the identification regions 2 are different, and therefore the five-pointed stars in the identification regions 2 display different colors, to indicate different degrees of the intensities of the ultraviolet irradiation.
The ultraviolet-photochromic ink itself may serve as the ultraviolet-photochromic marker. Alternatively, the ultraviolet-photochromic ink may also form the ultraviolet-photochromic marker after it has been semi-dried or dried. Preferably, the marker formed after the ink has been dried is employed, which facilitates the subsequent covering by the cover. The drying is the process in which the water in the ink is evaporated, and may be completed by natural air drying or by heating.
S104: in each of the identification regions 2, covering the ultraviolet-photochromic markers 3 by using covers 4 having different ultraviolet-ray blocking capacities.
The user can acquire the intensity of the ultraviolet irradiation of the current environment with naked eye according to the colors of the ultraviolet-photochromic markers 3 in the different identification regions 2. When the intensity of the ultraviolet irradiation is too high, the user can make protection according to his own condition, to prevent the irradiation of the ultraviolet ray of the high intensity. The component composition of the ultraviolet-photochromic ink may be varied, to provide suitable ultraviolet-photochromic markers 3 according to the different conditions of the users.
Further, each of the identification regions 2 provided with the ultraviolet-photochromic markers 3 used for marking is covered by ultraviolet-ray blocking films 5 having different quantities of stacked layers. The different identification regions 2 correspond to the ultraviolet-ray blocking films having the different quantities of the stacked layers. The ultraviolet-ray blocking film has a certain light transmittance, to enable the ultraviolet ray of a certain intensity to pass through the ultraviolet-ray blocking film, and also has a certain opacity. In other words, each layer of the ultraviolet-ray blocking films blocks or obstructs an ultraviolet ray. Higher quantities of the stacked layers of the ultraviolet-ray blocking films have more obvious effect of the blocking or obstructing.
In some embodiments, the identification regions 2 on the substrate 1 may be arranged in a sequence in which the quantities of the stacked layers of the covering ultraviolet-ray blocking films 5 are progressively increased or progressively reduced. In other words, the different identification regions 2 arranged in a sequence are covered by the ultraviolet-ray blocking films 5 whose quantities of the layers are progressively increased or progressively reduced, so that the darknesses of the colors of the ultraviolet-photochromic markers 3 are changed in a certain sequence. That facilitates the user to determine the irradiation intensity of an ultraviolet ray by observing the discoloration of the identification regions 2. In addition, the quantities of the stacked layers of the ultraviolet-ray blocking films 5 in the different identification regions 2 may be set according to requirements by the measurement by the user, to increase the adaptability of the product.
The cover may be formed by using any suitable ultraviolet-ray blocking materials. The cover may be provided in various suitable manners, for example, lamination.
The present disclosure further provides a smart apparatus. As shown in
In some embodiments, the smart apparatus 7 further comprises an image collecting component 10 (as shown in
In some embodiments, the smart apparatus 7 further comprises an alarming device configured for emitting alerting information according to the alerting signal. The alarming device comprises a sound alarming device and/or a displaying alarming device. The smart apparatus 7 emits visual alarming information by using the alarming device to directly alert the user. The alarming information may also be sound alarming information, to prevent that the user does not see the displayed contents of the smart apparatus 7, to improve the usage experience of the user.
In some embodiments, the smart apparatus 7 further comprises a storing component configured for storing intensity information, time information and location information corresponding to the image information. If, next time, the user enters the same location at the same time, even if the user does not start up the above-described ultraviolet-ray sensor, the smart apparatus 4 can give warning according to the intensity information stored by the storing component that corresponds to the current time and the current location, and the user may make protection as appropriate, which effectively improves the function and the intelligence of the smart apparatus 7.
In some embodiments, the smart apparatus 7 further comprises a data-connection component configured for connecting wirelessly to a mobile terminal of the user or a cloud device, to share the data. Other users may acquire the information on the ultraviolet intensity corresponding to the time and the location by using the cloud, to plan the particular travelling routine, to realize information sharing.
In some embodiments, in order to facilitate the installation and detaching of the ultraviolet-ray detecting device in the electronic device, the ultraviolet-ray detecting device 9 is detachably arranged at the housing 8, to facilitate the usage and the operation of the user, and the user may selectively use it according to his practical demands.
In some embodiments, a plug slot is provided at the housing 8, and the ultraviolet-ray detecting device 9 is arranged at the housing 8 via the plug slot. The ultraviolet-photochromic markers 3 in the identification regions 2 on the ultraviolet-ray detecting device 9 are required to be exposed in usage, to prevent affecting the effect of the discoloration of the ultraviolet-photochromic ink. The plug slot has a simple structure, and is easily operable by the user.
Over the prior art, the advantageous effects of the present disclosure are as follows. The present disclosure, by using the characteristic of the ultraviolet-photochromic ink of the ultraviolet-ray detecting device, i.e., the characteristic of the ultraviolet-photochromic ink that the color is darkened under an ultraviolet irradiation of a high intensity, enables the user to monitor in real time the intensities of ultraviolet irradiations in everyday life, to monitor at any time and at any place the intensity of the ultraviolet irradiation of the environment where he is located, and, when the intensity is too high, timely emits the protection alarming, and can realize customized designs for different people by regulating the component composition of the ultraviolet-photochromic ink or the thickness of the ultraviolet-ray blocking films. Especially, the ultraviolet-ray detecting device and the smart apparatus according to the present disclosure do not require a colorimetric card or a similar device. The product according to the present disclosure, by using the covers having the different ultraviolet-ray blocking capacities, has at the same time the plurality of identification regions that discolor under different ultraviolet intensities, and thus can enable the user to easily know the ultraviolet intensity by the sequential discoloration of the plurality of identification regions in environments whose ultraviolet rays are gradually intensified. Moreover, the customization by using the component composition of the ink or the quantity of the stacked layers of the ultraviolet-ray blocking films is particularly convenient and cheap.
