Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric blankets, in particular to an intelligent electric blanket. BACKGROUND

[0002] An electric blanket is a household appliance for heating, which has been invented and used a hundred years ago. Special electric heating elements are woven or sewn into the blanket, and heat is generated when electricity is supplied, which is transmitted to the human body through contact with the human body. It is mainly used to increase the temperature in the quilt to achieve the purpose of heating when people sleep, and can also be used to remove moisture from bedding. It has low power consumption, adjustable temperature, convenient use and low price, and is widely used.

[0003] At present, there are various types of electric blankets on the market, but their technical solutions are mostly to sew electric heating wires into the blanket, and to control the temperature by controlling the current in the electric heating wire. Although this can achieve the function of heating the electric blanket, the constant temperature will also cause the temperature at the center position to be too high. When the temperature exceeds the comfortable feeling of the human body, the human body will sweat, which not only reduces the comfort of use, but also is not conducive to the health of the human body. For example, Chinese patent No. CN105902079 B (publication date: March 16, 2018) discloses an intelligent electric blanket, which uses specially customized high-power heating wires to rapidly heat and warm up, uses a temperature detection unit, and after 5-10 minutes of detection, the electric blanket will intelligently switch to sleep mode, which will keep the electric blanket at a constant temperature of 35C-5C. Long-term use will not cause overheating and sweating, which will affect sleep. It can also be further adjusted according to the ambient temperature, and the system permanently memorizes the set temperature after the first use, so that subsequent use can achieve one-key start. It also has the functions of anti-ignition protection and countdown automatic shutdown to prevent the electric blanket from working for a long time when there is no one, which wastes energy and causes safety hazards. However, in daily life, the temperature of the surface of the electric blanket is not the same everywhere. Although the electric blanket can maintain a constant temperature to ensure that the entire blanket does not overheat and sweat, since the electric heating wire is a whole heating unit, the current flowing through the cold place and the current flowing through the hot place are the same. Therefore, the effect of solving the problem of too high or too low temperature at a certain point is not obvious. In addition, most of the electric blankets on the market are used indoors, and there are few electric blankets that can meet the needs of outdoor heating.

[0004] In view of the current situation of the above technical problems, the present application is dedicated to solving these problems, and therefore designs an intelligent electric blanket to overcome these technical problems. SUMMARY

[0005] The purpose of the present application is to provide an intelligent electric blanket, which improves the structure of the blanket and adds a practical and detachable module to solve the problems in the background art.

[0006] A smart electric blanket includes a blanket surface, a heating layer, a control component, and a foot pad. The heating layer is laid on a flat surface and is used to heat the blanket surface. Due to its elastic, perforated structure design, the heating layer can also provide better support and improve the breathability of the electric blanket. The blanket surface is fixedly installed on top of the heating layer. The blanket surface is used to eliminate static electricity and provide a soft and comfortable user environment. The control component is fixedly installed on the upper right corner of the blanket surface. The control component is used for signal input and feedback. A foot pad is rotatably installed on the bottom edge of the blanket surface. The foot pad is used to heat the user's feet when the electric blanket is rolled into a cylinder shape and to provide a sealing effect for the electric blanket.

[0007] Preferably, the heating layer includes a lower mounting fabric, elastic elements, heating elements, an insulating layer, and an adhesive layer. The lower mounting fabric is placed on the bed and should meet certain waterproof requirements. It is generally made of PTFE membrane and composite material. The elastic element array is fixedly installed above the lower mounting fabric at intervals. The elastic element is a rubber spring with an elastic modulus of less than 110 GPa. Compared with metal springs, rubber springs have a smaller elastic modulus, greater elastic deformation under load, can absorb impact and vibration, have a long service life, low cost, and good cold resistance, excellent airtightness, waterproofness, and electrical insulation. It is the best choice for shock absorption. Electric blankets made from this material are particularly suitable for use in places with high vibration, such as construction sites. The rubber springs are lightweight and their shape is not restricted. Cavities can be set inside to fix the heating element. Since the elastic element is arranged in an array, it is surrounded by cavities. These cavities can be connected to the outside air to achieve a breathable effect. Through this structure, heat is not directly transferred to the body through the fabric, but is heated by the air, making the heating more uniform and avoiding the situation where the heat is too high in one place or around the heating wire while the temperature is low in other places. An insulating layer is fixedly installed on top of the elastic element, and an adhesive layer is fixedly installed on top of the insulating layer.

[0008] Preferably, the blanket surface includes an anti-static layer, a temperature detection module, filling material, an upper mounting fabric, and pile. The anti-static layer is fixedly mounted on the heating layer adhesive layer. The temperature detection module is fixedly mounted above the anti-static layer. The temperature detection module is a temperature sensor with a temperature detection range of -20℃ to 80℃. There are multiple temperature sensors arranged in an alternating manner, and each sensor is connected to the others by a lead wire. This more human-fitting design can better reflect real-time temperature and provide a better user experience. The temperature detection module is electrically connected to the control component. The filling material is arranged around the temperature detection module. The upper mounting fabric is fixedly mounted above the temperature detection module and the filling material. The pile is planted on the upper mounting fabric in a cross-shaped arrangement. Compared with the traditional array arrangement, this arrangement structure provides better elasticity.

[0009] Preferably, the blanket surface has ventilation holes, which are circular through holes with a diameter ranging from 0.05mm to 0.1mm. The ventilation holes can communicate with the hollow structure in the heating layer, realizing the ventilation function of the blanket bottom when the blanket is used, and avoiding the situation of excessive heat accumulation caused by prolonged use of the blanket.

[0010] Preferably, the carpet surface can be bent into a barrel-shaped structure, and magnetic attraction devices are embedded at both ends of the carpet surface. The magnetic attraction devices can be ordinary ferrite magnets, strong alloy magnets such as neodymium iron boron, or lightweight rubber magnetic strips. They can be selected as needed according to different scenarios. The magnetic force coverage of the magnetic attraction devices is not less than 2 / 3 of the width of the carpet surface.

[0011] Preferably, an insect repellent module is detachably installed along the edge of the blanket. In outdoor camping, there are many mosquitoes, and mosquito sprays evaporate easily in an unsealed environment, making them impractical. Mosquito coils, on the other hand, pose a fire hazard. To address this, the insect repellent module is symmetrically installed on the side of the blanket near the head. The insect repellent module is a strip-shaped bag structure that can contain insect hormone-based insect repellent. When used, the residual heat of the blanket edge causes the drug to evaporate, achieving the purpose of repelling insects.

[0012] Preferably, the heating layer has a segmented structure, with the reinforcing ribs fixedly installed at the joints of each segment. The reinforcing ribs are used to distribute the pressure and prevent the elastic element in the center from aging faster due to frequent exposure to higher pressure. The segmented design increases the service life of the invention.

[0013] Preferably, the heating layer is bonded to the blanket surface with adhesive. The adhesive is an environmentally friendly hot melt adhesive, which is a plastic and environmentally friendly adhesive with characteristics such as soft texture, high bonding strength, easy use, fast curing, transparency, extremely low odor, and waterproof and high temperature resistance after complete curing. It is suitable for fabrics and has little harm to the human body. The adhesive has a minimum viscosity of 200 CPS in an environment of -20℃ to 200℃, which can meet the requirements for bonding fabrics.

[0014] Preferably, the control component is embedded in the blanket body and electrically connected to the heating unit, the temperature detection module, and the external power supply. The control component is slightly higher than the blanket surface by 2mm. The control component is equipped with a start button, a stop button, a heating button, a cooling button, and a temperature control display screen. The temperature control display screen can display the real-time temperature. The control component has a built-in algorithm chip that comprehensively calculates the data from multiple temperature sensors to obtain the most reasonable data. The control component has a memory function, and the set temperature can be automatically inherited when used again.

[0015] Preferably, the foot pad includes a mounting fabric, a heating module, an anti-static layer, fleece, and a digital interface. The mounting fabric is placed on the bed, and the heating module is fixedly mounted on top of it. The heating module is a common heating wire, semi-circular in shape, with four coils, and connected outward to the digital interface to obtain electrical energy from the blanket body through the digital interface. The anti-static layer is fixedly mounted on top of the heating module, and the mounting fabric is fixedly mounted on top of the anti-static layer. The fleece is planted on top of the mounting fabric. The digital interface is externally connected to the heating module, and the digital interface is a circular interface with an input voltage and current of 20V / 3.5A.

[0016] Preferably, the foot pad has a semi-circular structure and is connected to the blanket surface by a zipper. When used at home, the foot pad can be detached, and when used outdoors, it can be added. The foot pad is fixedly installed with a hook, and the hook has an elastic rope in the middle. When the blanket surface is bent into a barrel shape, the hook can be stretched onto the elastic band of the blanket body to fix the entire blanket structure and make the entire blanket body more enclosed, preventing wind from blowing into the blanket body through the gaps.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention improves the support effect of the electric blanket while ensuring its breathability by setting a large number of elastic elements and opening ventilation holes on the blanket surface. At the same time, the magnetic attraction device designed along the edge of the blanket allows the blanket to be rolled into a cylindrical shape, which greatly enhances the practicality of the blanket in outdoor situations. The foot pad is also provided, which can heat the user's feet and fix the cylindrical blanket body.

[0019] 2. The present invention provides an intelligent electric blanket that improves the support effect of the electric blanket by adding the elastic element to the heating layer. Because the human body is a curved shape, only a highly elastic bed can provide support for the body and back, allowing the body to relax and rest fully. Furthermore, the human spine has a shallow S-shape, requiring support with appropriate firmness when lying down. An elastic electric blanket is crucial for comfort and sleep quality. Simultaneously, the array-like arrangement of the elastic element creates a perforated structure around the blanket, which, in conjunction with the ventilation holes on the blanket surface, ensures air circulation under the blanket, preventing excessive heat accumulation in the center of the bed and improving comfort.

[0020] 3. The present invention provides an intelligent electric blanket, which improves its practicality outdoors by installing a detachable insect repellent module on the edge of the blanket and adding volatile insect repellent drugs into the module. When the electric blanket is used, the increased temperature causes the drugs to evaporate and repel insects.

[0021] 4. The present invention provides an intelligent electric blanket, which is designed with a magnetic suction device that can roll the electric blanket into a cylindrical shape and is equipped with a detachable foot pad. Hooks are fixedly installed on the left and right sides below the foot pad, which achieves the sealing of the entire blanket and ensures the temperature of the feet and legs. This avoids the situation where the leg temperature is too low or the gaps leak air, which may cause discomfort to the user and improves the functionality of the present invention.

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] Example 1: As Figure 1 As shown, a smart electric blanket includes a blanket surface 1, a heating layer 2, a control component 3, and a foot pad 4. The heating layer 2 is placed horizontally and is used to heat the blanket surface 1 and support the entire blanket. The blanket surface 1 is fixedly installed above the heating layer 2 and is used to eliminate static electricity and provide a soft and comfortable user environment. The control component 3 is fixedly installed at the upper right corner of the blanket surface 1 and is used for signal input and feedback. The foot pad 4 is rotatably installed on the bottom edge of the blanket surface 1 and is used to heat the user's feet.

[0036] like Figure 3As shown, the heating layer 2 includes a lower mounting fabric 21, elastic elements 22, heating elements 23, reinforcing ribs 24, an insulating layer 25, and an adhesive layer 26. The lower mounting fabric 21 is the bottom layer closest to the ground and serves to encapsulate the electric blanket. The lower mounting fabric is made of synthetic fiber from a high-molecular composite material. This material has good toughness, wear resistance, and a certain degree of waterproofing. As an electrical appliance, the electric blanket requires a certain degree of waterproofing, and this design can improve its waterproofing function. The elastic elements 22 are fixedly installed in an array at intervals above the lower mounting fabric 21. The elastic elements 22 here are rubber springs. Compared with metal springs, rubber springs have a smaller elastic modulus and exhibit greater elastic deformation under load. It can absorb shock and vibration, has a long service life, low cost, good cold resistance, excellent airtightness, waterproofness, and electrical insulation. It is the best choice for cushioning and vibration reduction. Therefore, electric blankets made of this material are especially suitable for use in places with large vibrations, such as construction sites. Moreover, the rubber springs are lightweight, so the electric blanket will not be bulky and inconvenient to carry. Its shape is also not limited. A cavity can be set inside to fix the heating element 23. Due to the array arrangement of the elastic elements 22, many air cavities will be generated around it, which improves the breathability of the electric blanket. In addition, the heat will be more evenly distributed through the conduction of the air at the bottom, so that there will be no situation where the temperature is too high or too low at any point.

[0037] like Figure 4 As shown, the heating element 23 is fixedly installed in the elastic element 22. An insulating layer 25 is fixedly installed above the elastic element 22. As a charged body, the heating wire will generate a certain magnetic field, which is not good for human health. Therefore, it is necessary to design an insulating layer to shield the magnetic field. An adhesive layer 26 is fixedly installed above the insulating layer 25. The adhesive layer 26 is used to bond with the carpet surface 1. Here, glue is used as the connecting medium. The glue is an environmentally friendly hot melt adhesive.

[0038] like Figure 3 As shown, the heating layer 2 has a segmented structure, with reinforcing ribs 24 installed at the junction of each two segments. The reinforcing ribs are used to fix the blanket structure, prevent the blanket from shifting when subjected to horizontal stress, and distribute the pressure. This avoids the elastic element in the center from aging faster due to frequent exposure to higher pressure, and also ensures that no obvious dents appear in the middle part after long-term use.

[0039] like Figure 5As shown, the blanket surface 1 includes an antistatic layer 11, a temperature detection module 12, filling material 13, an upper mounting fabric 14, and pile 15. The antistatic layer 11 is fixedly installed on the heating layer adhesive layer 25. The antistatic layer 11 is used to eliminate static electricity carried by energized components such as heating wires and thermistors, preventing static electricity from harming the human body. The temperature detection module 12 is fixedly installed above the antistatic layer 11. Here, the temperature detection module 12 uses a thermistor as a temperature sensor 121. Figure 7 As shown, multiple temperature sensors 121 are arranged at various locations above the static elimination layer 11. Each temperature sensor 121 is connected via a lead wire 122. The multiple temperature sensors 121 help to understand the temperature of the electric blanket at different locations, preventing situations where the blanket is too cold or too hot. Compared to traditional electric blankets, the temperature detection module 12 does not directly measure the temperature around the heating wire, but is closer to the human body. This design provides better feedback on the temperature perceived by the user, offering a better user experience. The enclosure is provided with the filling material 13. The upper mounting fabric 13 is fixedly installed above the temperature detection module 12 and the filling material 13. Because the upper mounting fabric 13 is close to the human body, its functional requirements are different from those of the lower mounting fabric. The upper mounting fabric 13 should meet the requirements of softness, comfort and breathability. Here, it is made of pure cotton. The upper mounting fabric 13 is covered with the pile 14. The pile 14 is arranged in a cross pattern. Compared with the straight pattern, this arrangement can provide better support. The pile material is made of cotton, which has the advantages of softness and breathability, thus improving the comfort of use.

[0040] like Figure 9 As shown, the control component 3 includes a start button 31, a stop button 32, a heating button 33, a cooling button 34, and a display screen 35, which respectively control the electric blanket's power-on, power-off, set temperature increase, and set temperature decrease functions. The display screen shows the real-time temperature of the blanket surface and the current heating status, such as "heating up" and "keeping warm". The control component has a built-in microcontroller chip that can record the usage temperature, and the set temperature will automatically be the temperature when it was last turned off when used next time.

[0041] like Figure 8As shown, an insect repellent module 5 is detachably installed on the upper edge of the blanket surface 1. This is an external module that can be installed according to the user's needs. For example, when travelers camp or workers live on construction sites, there are usually many mosquitoes nearby. Since the user's living space is often not a closed space, the effect of using mosquito coils or insecticides will be greatly reduced. In this case, the insect repellent module 5 can be installed on the blanket. The insect repellent module 5 is connected to the edge of the blanket surface 1 by Velcro, which is very convenient to use. The core of the insect repellent module 5 is a plastic tube. After being installed on the blanket, insect repellent drugs such as insect hormones can be placed inside it. When the temperature of the electric blanket rises, the insect repellent drugs will evaporate to achieve the purpose of repelling mosquitoes.

[0042] like Figure 10 and Figure 11 As shown, the smart electric blanket includes a detachable foot pad 4. The foot pad 4 includes a mounting fabric 41, a heating module 42, an anti-static layer 43, fleece 44, a digital interface 45, and a zipper 46. The mounting fabric 41 is placed on a flat surface, and the heating module 42 is fixedly mounted on top of the mounting fabric 41. The heating module 42 consists of multiple semi-circular heating wires connected by leads and finally connected to the digital interface. The digital interface obtains signals and electrical energy from the blanket body. The anti-static layer 43 is fixedly mounted on top of the heating module 42, and the mounting fabric 41 is fixedly mounted on top of the anti-static layer 43. The mounting fabric 41 is made of pure cotton material, which is soft and breathable, providing a comfortable feel for the user's feet and preventing sweating. The fleece 44 is attached to the top of the mounting fabric 41. The digital interface 45 is connected to the heating module 42. Since existing electric blankets are mostly used indoors and are typically laid directly on beds, they are inconvenient for users when they need to use them outdoors. When users need to use this invention outdoors, such as in a tent, they first roll the blanket body consisting of the heating layer 2 and the blanket surface 1 into a cylindrical shape, and then bend the foot pad 4 along the connecting edge between the two. The surface of the rolled part and the foot pad part is heated by the control component. Since the soles of the human feet are perpendicular to the ground, they fit perfectly against the vertically bent foot pad part, thereby achieving the effect of heating the soles of the human feet.

[0043] Example 2: When users are at home, they often wear slippers and sit on sofas or chairs. Therefore, their heels become exposed for extended periods, leading to lower foot temperatures. Low foot temperatures can cause discomfort. In this case, the invention can be placed on the floor, with the foot pad 4 as a fixing point, and the rolled section bent vertically. Then, the hooks 47 on the foot pad 4 are used to connect the foot pad to the rolled section. After fixing, the user places their lower legs into the rolled blanket, and the heating circuits around the edges and bottom heat the feet and legs. This achieves the effect of heating the feet, which are susceptible to low temperatures, while the user is seated.

[0044] In this embodiment, as Figure 11 As shown, a magnetic attraction device 16 is provided on the upper surface of one end of the roll portion and the lower surface of the other end. The magnetic attraction device 16 uses a rubber magnetic strip. Since this invention needs to be used on both the bed and the floor, a connection method with quick adhesion and disassembly is required to fix the two sides of the roll portion together. Compared with common connection methods such as zippers or buttons, rubber magnetic strips have the advantages of not irritating the skin, better sealing, and quick disassembly, making them more suitable as a connection method for the roll portion. This can improve the ease of operation of this invention.

[0045] Example 3: The connection between the blanket surface 1 and the heating layer 2 can also be made using a zipper. A zipper connection allows the blanket surface 1 and the heating layer 2 to be used as two independent devices. When the weather gets cold and the user needs warmth from this invention, the heating layer 2 can be installed under the blanket surface 1 via the zipper to achieve the purpose of warmth. When the temperature rises and the user no longer needs the electric blanket, the heating layer 2 can be removed from the blanket surface 1, and the blanket surface can be used as a regular blanket. Using a zipper connection also facilitates inspection and maintenance. When the electronic components inside the blanket are damaged, simply unzipping the zipper will reveal which component is malfunctioning. Furthermore, as the electric blanket ages over time, the electronic components will not necessarily become unusable, and the blanket surface can still be used, reflecting a spirit of thrift and economy.

[0046] Working principle of the invention: When using this smart electric blanket, the user first lays the blanket surface 1 and heating layer 2 on the bed, then lays a sheet on the blanket surface, and then powers on the electric blanket. The temperature of the electric blanket is adjusted by the control component 3. After the temperature is set, the heating element 23 starts to heat. The temperature of the blanket is collected by the temperature sensor 121 and transmitted to the control component 3 through the lead wire 122. When the temperature feedback value reaches the set value of -1℃, the heating wire changes its current, and the electric blanket changes from heating state to heat preservation state. The electric blanket is equipped with a variety of elastic elements to adapt to the support required by the human body. The hollow structure design of the heating layer also makes the heating process more stable and balanced.

[0047] When the user uses the blanket outdoors, the insect repellent module 5 is installed on the upper edge of the blanket surface 1. When using it, insect hormone-based insect repellent drugs are added to it first, and then the electric blanket is heated. The temperature is conducted to the insect repellent module, and the drug inside begins to evaporate, achieving the insect repellent effect.

[0048] When using this smart electric blanket, the foot pad is installed on the blanket via zipper 46. Then, the blanket body, consisting of the blanket surface 1 and the heating layer 2, is bent into a cylindrical shape and fixed by magnetic devices on both sides to prevent it from spreading out. Next, the foot pad is flipped up and the hook 47 on the foot pad is pulled onto the elastic band of the blanket body to fix and seal the entire blanket body. Finally, the digital interface between the blanket body and the foot pad 4 is connected to transmit signals and current to the foot pad 4.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
