Description

Technical Field

[0001] This utility model relates to the field of mattress heating, specifically a heating device based on an air-filled mattress. Background Technology

[0002] A heating pad is a device used for localized heat therapy on the human body. It is usually connected to a power source to generate internal heat, thereby providing heat therapy to a specific area of ​​the body. Heating pads are mainly used for localized heat application, achieving the effect of relaxing and providing health benefits to that area through heating. Graphene is a new carbon material with carbon atoms arranged in a single-layer two-dimensional honeycomb lattice structure. It has excellent thermal conductivity and is widely used in electronics, energy, chemical industry, materials and other fields. Therefore, graphene can be used as an additive in composite materials to improve the thermal conductivity of materials.

[0003] Patent application number 202323089381.9 discloses a heating device based on an inflatable mattress, including a heating pad and a fixing clip. The fixing clip is fixedly disposed at both ends of the heating pad to clamp and fix both ends of the heating pad to the inflatable mattress. The fixing clip includes a chamfered part and a clamping part. The chamfered part is in the shape of a rounded end, and the clamping part is disposed at the free end of the chamfered part. The two sets of clamping parts are arranged parallel to each other. By installing the skirts at the head and foot of the inflatable mattress into the two sets of clamping parts, the clamping parts achieve a fixing effect, solving the problem of the heating pad easily sliding and shifting on the bed. The heat insulation layer is made of non-woven fabric, which has a heat insulation effect and can prevent the heating layer from causing aging of the inflatable mattress, thus extending the service life of the inflatable mattress. The skin-friendly surface layer is made of pure cotton, which has good comfort.

[0004] However, in practical applications, traditional heating devices based on air mattresses use a fixing clamp to limit the heating pad and prevent it from shifting. This only blocks the two ends of the heating pad and does not directly limit its position, which can still easily lead to displacement. Moreover, placing the entire graphene heating film in the heating pad will heat the user as a whole during heating, reducing the adjustability of the heating.

[0005] For example, traditional air mattress heating devices typically use clamps to restrict the position of the heating pad and prevent it from moving. However, this setup only blocks the two ends of the heating pad and does not directly limit or fix the heating pad itself. Therefore, in actual use, especially when the user turns over or moves, the heating pad is prone to wrinkles, bulges, or even slippage due to compression or pulling. These wrinkles and bulges not only affect the tight fit between the heating pad and the air mattress, resulting in uneven heating, but also cause discomfort to the user. Especially when the user turns over, the displacement of the heating pad will cause the areas that need heat to lose heat, while the areas that do not need heat will become overheated, greatly reducing the user experience of the heating device. Moreover, existing heating pads often embed the entire graphene heating film, heating the entire body of the user. However, in reality, users usually only need to heat specific areas of the body, such as the waist or legs. The entire heating film means that areas that do not need heat will also be affected by heat, which not only wastes energy but also easily causes the user to feel overheated in areas that do not need heat, thus reducing the adjustability and flexibility of the heating device. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a heating device based on an air mattress. This addresses the problem that current traditional air mattress-based heating devices use a fixing clamp to limit the heating pad and prevent displacement. However, this only blocks the two ends of the heating pad and does not directly limit its movement, making displacement still possible. Furthermore, placing the entire graphene heating film in the heating pad results in overall heating of the user, reducing the technical problem of adjustable heating.

[0007] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a heating device based on an air mattress is designed, including an air-filled base pad. Each of the four corners of the top of the air-filled base pad is connected to an air inlet connector. A sealing groove is opened at the top of the air inlet connector. An air inlet is opened at the bottom of the sealing groove. A rubber sealing ring is sealed and engaged inside the sealing groove. An air inlet pipe is fixed inside the rubber sealing ring. The bottom of the air inlet pipe passes through the air inlet and extends into the air-filled base pad. A miniature air pump is connected to the top of the air inlet pipe. A heating component is installed between multiple miniature air pumps.

[0008] In practical applications, multiple air inlet connectors are set on the surface of the inflatable base pad. These connectors can be sealed and snapped into the inflation pipes and rubber sealing rings at the bottom of multiple micro air pumps. The sealing rubber rings are snapped into the sealing grooves of the air inlet connectors, while the charging pipes pass through the inflation holes. This not only allows for direct positioning of the heat insulation pad, graphene heating film, and skin-friendly surface layer after the multiple micro air pumps are connected, preventing displacement during the user's turning over, but also allows for direct inflation of the air mattress after the micro air pumps are connected to the air inlet connectors, eliminating the need for external inflation equipment. This integrated inflation and positioning mechanism is designed as a single unit.

[0009] Preferably, the heating component includes a heat insulation pad, a graphene heating film, and a skin-friendly surface layer.

[0010] Preferably, the heat insulation pad is fixed between multiple micro air pumps, and a skin-friendly surface layer is installed on its top. Multiple graphene heating films are installed between the heat insulation pad and the skin-friendly surface layer.

[0011] In practical applications, multiple graphene heating films are placed between the skin-friendly surface layer and the heat insulation pad. Multiple small graphene heating films can be used to form multi-zone heating between the skin-friendly surface layer and the heat insulation pad. The graphene heating film at the corresponding position can be controlled to heat according to the local heating position of the patient. This not only saves energy, but also avoids the user feeling overheated in areas that do not need heating, and improves the adjustability and flexibility of the heating device.

[0012] Preferably, the heat insulation pad has multiple chambers inside, and an airbag is installed inside each chamber. The front end of the airbag is connected to one end of a hose, and the other end of the hose is connected to an electric air pump.

[0013] In practical applications, multiple airbags are installed inside the heat insulation pad. During the process of local heating by the user, multiple electric air pumps can be activated to repeatedly inflate and expand the airbags. This allows for repeated compression therapy and massage of the user during local heating, thus enhancing the functionality of the device.

[0014] Preferably, the electric air pump is installed in a mounting hole on the surface of the housing, and the front end of the electric air pump is connected to an air inlet pipe.

[0015] Preferably, a temperature controller is installed on the top of the housing, and the temperature controller is connected to multiple graphene heating films.

[0016] Preferably, both sides of the front bottom of the inflatable base pad are connected to one end of an inflation tube, and the other end of the inflation tube is detachably connected to a tube cap.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. After multiple air inlet connectors are connected to the micro air pump, the heat insulation pad, graphene heating film, and skin-friendly surface layer of this utility model can be directly limited, effectively preventing displacement when the user turns over or moves, thus improving the stability of the mattress. Moreover, after the micro air pump is connected to the air inlet connectors, the air mattress can be directly inflated without the need for external inflation equipment, simplifying the inflation process and improving the convenience of use. By integrating the inflation mechanism and the limiting mechanism into one unit, the number of parts is reduced, the structure is simplified, and the overall integrity and reliability of the product are improved.

[0019] 2. This utility model incorporates multiple small graphene heating films between the skin-friendly surface layer and the heat insulation pad to achieve multi-zone heating. Simultaneously, it integrates multiple air bladders within the heat insulation pad, connected to an electric air pump, allowing for inflation and deflation as needed, achieving repeated expansion and contraction. During localized heating, the expansion of the air bladders causes the graphene heating films to adhere tightly to the user's body, providing a more body-conforming heating experience. Furthermore, the dynamic compression therapy massage function further enhances the heat therapy effect, strengthening the device's functionality and usability. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A heating device based on an air mattress, see [link to example]. Figures 1 to 4The device includes an inflatable base pad 1. Each of the four corners of the top of the inflatable base pad 1 is connected to an air inlet connector 204. The top of the air inlet connector 204 is provided with a sealing groove 202. The bottom of the sealing groove 202 is provided with an inflation hole 201. A rubber sealing ring 208 is sealed and engaged inside the sealing groove 202. An inflation pipe 209 is fixed inside the rubber sealing ring 208. The bottom of the inflation pipe 209 passes through the inflation hole 201 and extends into the inflatable base pad 1. A miniature air pump 203 is connected to the top of the inflation pipe 209. A heating component 2 is installed between multiple miniature air pumps 203.

[0027] Specifically, multiple air inlet connectors 204 are provided on the surface of the inflatable base pad 1. When the air mattress is needed, multiple miniature air pumps 203 are inserted into the sealing grooves 202 and inflation holes 201 of the air inlet connectors 204 through their bottom rubber sealing rings 208 and inflation pipes 209, completing the connection between the air pumps and the inflatable base pad 1. The rubber sealing rings 208 are tightly fitted into the sealing grooves 202 of the air inlet connectors 204, ensuring the airtightness of the connection and preventing gas leakage. At the same time, the inflation pipes 209 pass through the inflation holes 201 of the air inlet connectors 204 and enter the inflatable base pad 1. When the rubber sealing rings 208 and inflation pipes 209 are inserted into the sealing grooves 202 and inflation holes 201, Not only does it connect the air pump to the base pad, but it also directly limits the heat insulation pad 206, graphene heating film 207, and skin-friendly surface layer 205. This limiting effectively prevents relative movement during the user's turning over or shifting, ensuring the stability and comfort of the mattress. After the connection is completed, multiple micro air pumps 203 can be activated to directly deliver gas to the interior of the air-filled base pad 1 through the inflation pipe 209. As gas is continuously injected, the air-filled base pad 1 gradually expands, achieving the required firmness and support. The entire process does not require the use of external inflation equipment, realizing the integrated design of the inflation mechanism and the limiting mechanism, which greatly simplifies the use and operation of the air mattress.

[0028] For example, traditional air mattress heating devices typically use clamps to restrict the position of the heating pad and prevent it from moving. However, this only blocks the two ends of the heating pad and does not directly limit or fix the heating pad itself. Therefore, in actual use, especially when the user turns over or moves, the heating pad is prone to wrinkles, bulges, or even slipping from the side due to compression or pulling. These wrinkles and bulges not only affect the tight fit between the heating pad and the air mattress, resulting in uneven heating, but also cause discomfort to the user. Especially when the user turns over, the displacement of the heating pad causes areas that need heat to lose heat, while areas that do not need heating become overheated, greatly reducing the user experience of the heating device.

[0029] In practical use, this solution involves multiple miniature air pumps 203 being inserted into the sealing groove 202 and inflation hole 201 of the air inlet connector 204 via rubber sealing rings 208 and inflation pipes 209, thus connecting with the inflatable base pad 1. This not only directly limits the heat insulation pad 206, graphene heating film 207, and skin-friendly surface layer 205, preventing relative movement when the user turns over or shifts, but also, after connection, starting the miniature air pumps 203 directly inflates the inflatable base pad 1 through the inflation pipes 209, causing it to gradually expand to achieve the required hardness and support. The entire process requires no external inflation equipment, achieving integrated inflation and limiting mechanisms, simplifying the use and operation process.

[0030] For details, see Figure 2 The heating component 2 includes a heat insulation pad 206, a graphene heating film 207, and a skin-friendly surface layer 205.

[0031] Further, see Figure 2 The heat insulation pad 206 is fixed between multiple micro air pumps 203, and a skin-friendly surface layer 205 is installed on its top. Multiple graphene heating films 207 are installed between the heat insulation pad 206 and the skin-friendly surface layer 205.

[0032] Specifically, multiple small graphene heating films 207 are evenly arranged between the skin-friendly surface layer 205 and the heat insulation pad 206. These graphene heating films 207 are divided into multiple heating zones, each of which can be independently controlled by a temperature controller 302, achieving multi-zone heating. This allows for precise heating of local areas according to the patient's specific needs. The device is equipped with a temperature controller to monitor and control the temperature of each heating zone. The temperature controller receives heating parameters set by the user (such as heating zone, target temperature, etc.) to control the heating state of the graphene heating film 207 at the corresponding position. When the user needs to heat a specific area, the temperature controller sends a signal to the graphene heating film 207 in that area to start heating. Meanwhile, the temperature controller will monitor the temperature of the area in real time and adjust the heating power according to the feedback information to ensure that the temperature is kept within the set range. Due to the use of multi-zone heating, users can select the heating area according to their actual needs, avoiding wasting energy in areas that do not need to be heated and improving the energy utilization rate of the heating device. At the same time, multi-zone heating also prevents users from feeling overheated in areas that do not need to be heated. Users can adjust the temperature of each heating area according to their own comfort preferences, thereby obtaining a more personalized heating experience.

[0033] For example, existing heating pads often embed the entire graphene heating film 207 into the heating pad, which heats the user's entire body when heated. However, in reality, users usually only need to apply heat to specific parts of the body, such as the waist or legs. The entire heating film means that areas that do not need to be heated will also be affected by heat, which not only wastes energy but also easily causes users to feel overheated in areas that do not need to be heated, thereby reducing the adjustability and flexibility of the heating device.

[0034] In practical application, this solution involves placing multiple small graphene heating films 207 between the skin-friendly surface layer 205 and the heat insulation pad 206 to achieve multi-zone heating. The heating film at the corresponding location can be controlled according to the patient's local heating needs, saving energy and preventing overheating of areas that do not require heating, thus improving the adjustability and flexibility of the heating device.

[0035] It is worth noting that, see Figure 3 The heat insulation pad 206 has multiple chambers 305 inside, and an airbag ball 306 is installed inside the multiple chambers 305. The front end of the airbag ball 306 is connected to one end of the hose 3, and the other end of the hose 3 is connected to an electric air pump 304.

[0036] Specifically, when a user needs localized heating combined with compression therapy massage, the electric air pump 304 is activated. The electric air pump 304 begins operation, inflating the airbag 306 through the hose 3. As the airbag is inflated, the airbag 306 gradually expands, applying gentle compression pressure to the user's body. Then, the electric air pump 304 stops inflating and begins deflating the airbag 306 through the hose 3. As the air is deflated, the airbag 306 gradually contracts, releasing the compression pressure on the user's body. The electric air pump 304 repeatedly inflates and deflates the airbag 306. This repeated expansion and contraction simulates the effect of manual massage, providing compression therapy massage to the user's body. Simultaneously, the expansion and contraction of the airbag 306 causes the heating component 2 (such as the graphene heating film 207) in the device to conform to the user's body curves for localized heating. This combination of heating and massage not only improves user comfort but also promotes blood circulation, relieves muscle tension, and enhances the functionality of the device.

[0037] For example, traditional solutions only have local heating function and lack massage effect, so users cannot enjoy the comfort of heating and the relaxation effect of massage at the same time.

[0038] In practical use, this solution simulates the effect of manual massage by expanding and contracting the airbag ball 306, while combining the local heating function of the graphene heating film 207 to achieve simultaneous heating and massage. This not only improves the user's comfort but also promotes blood circulation, relieves muscle tension, and enhances the functionality of the device.

[0039] It is worth noting that, see Figure 1 The electric air pump 304 is installed in the mounting hole 303 on the surface of the housing 301, and the front end of the electric air pump 304 is connected to the air inlet pipe.

[0040] It is worth mentioning that, see Figure 1 A temperature controller 302 is installed on the top of the housing 301, and the temperature controller 302 is connected to multiple graphene heating films 207.

[0041] It is worth emphasizing that, see Figure 1 The inflatable base pad 1 has one end of an inflation tube 101 connected to both sides of the front bottom, and the other end of the inflation tube 101 is detachably connected to a tube cap 102.

[0042] It should be noted that the specific model of temperature controller 302 is Yudian AI-719 temperature controller 302. Features: It has multiple adjustment modes such as standard PID, AI artificial intelligence adjustment APID or MPT, and has self-tuning and self-learning functions. It has excellent control characteristics with no overshoot and no undershoot. At the same time, it supports dual independent parameter PID and can support heating / cooling dual output functions, making it very suitable for controlling multiple graphene heating films 207.

[0043] The Yudian AI-719 temperature controller 302 controls multiple graphene heating films 207 via relays or solid-state relays (SSRs), with each heating film connected to the output of an independent relay or SSR.

[0044] The temperature controller 302 outputs a control signal based on the set temperature value to control the on / off state of the relay, thereby adjusting the heating power of the heating film;

[0045] When the inflatable base pad 1 needs to be used alone, after the inflatable base pad 1 is inflated, the plug of the matching air inlet connector 204 can be directly inserted into the air inlet connector 204 to achieve a seal of the air inlet connector 204.

[0046] The specific model of the electric air pump 304 is BOMPOW electric air pump 304. Function: Integrates inflation and deflation, it can be used for both inflation and deflation. Voltage and power: AC 230V, rated power 300W, with powerful inflation and deflation capabilities. Pressure: High pressure up to 1.2PSI (about 8000Pa), which can easily meet various inflation needs.

[0047] Inflation process of the airbag bulb 306: Connect the BOMPOW electric air pump 304 to the controller of the electric air pump 304 (model: MD-S910 digital display intelligent pressure controller. The MD-S910 digital display intelligent pressure controller has intelligent control function and can automatically control the start and stop of the electric air pump 304 through the preset air pressure value. When the air pressure in the airbag bulb 306 reaches the preset upper limit value, the controller will send a signal to stop the electric air pump 304 from working. When the air pressure drops to the preset lower limit value, the controller will start the electric air pump 304 to continue inflating). Connect the air nozzle interface tightly to the inflation port on the airbag bulb 306 through the hose 3. Then plug in the power and press the start button on the electric air pump 304. The BOMPOW electric air pump 304 starts to work and quickly compresses the outside air into the airbag bulb 306. The MD-S910 controller for the electric air pump 304 controls its operation by monitoring the air pressure inside the airbag bulb 306 in real time. When the airbag bulb 306 inflates to the required level, i.e., when the air pressure reaches the preset upper limit, the MD-S910 controller sends a signal to stop the electric air pump 304 from operating. At this time, the airbag bulb 306 remains inflated. Next, the MD-S910 controller activates the deflation mode of the electric air pump 304 to initiate the deflation function. The electric air pump 304 changes the airflow direction, extracting the air from the airbag bulb 306. As the air is continuously extracted, the airbag bulb 306 gradually contracts. When the airbag bulb 306 contracts below the preset lower limit, the MD-S910 controller sends another signal to activate the inflation mode of the electric air pump 304. The electric air pump 304 then restarts, forcing external air into the airbag bulb 306, causing it to gradually inflate. Under the control of the MD-S910 digital display intelligent pressure controller, the electric air pump 304 performs cyclic inflation and deflation operations, thereby realizing the expansion and contraction of the airbag bulb 306.

[0048] The specific model of the miniature air pump 203 is Xinweicheng F08 series miniature air pump 203, with rated voltage: 12V DC, flow rate: ≥210mL / min, maximum vacuum degree: ≥-46kPa, maximum output pressure: ≥80kPa, motor type: BLDC, and long service life, up to 12,000 hours or more.

[0049] First insulation layer: High-density polyurethane foam is used. Polyurethane foam has good thermal insulation properties, softness and durability.

[0050] The second insulation layer uses high-density polyurethane foam. In addition, to enhance the stability and durability of the insulation layer, fibers or grid structures can be added to the foam.
