Description

Technical Field

[0001] This utility model discloses a heated inflatable lumbar pillow, belonging to the field of health care lumbar pillow technology. Background Technology

[0002] In today's fast-paced society, with changes in work styles and lifestyles, prolonged sitting and poor posture have become widespread. This phenomenon is not only increasingly common in study and work but also profoundly impacts people's quality of life. Maintaining the same sitting posture for extended periods, especially without proper lumbar support, often leads to muscle tension and soreness in the lower back, and can even trigger lumbar spine diseases such as herniated discs and lumbar muscle strain. These problems not only cause physical pain but also seriously affect work efficiency and quality of life.

[0003] In existing technologies, heated lumbar pillows mostly use heating wires as heating elements. This method not only heats up slowly but also poses certain safety hazards, such as overheating or short circuit risks. Furthermore, as an auxiliary tool for supporting the lower back, the height of a lumbar pillow varies depending on the height, body type, and gender. Traditional lumbar pillows, although often designed to match the curve of the spine to provide better support, mostly use a standardized structure—a fixed height and shape—which fails to meet the personalized support needs of different users.

[0030] Preferably, the insulating layer is made of latex or cotton.

[0031] The protective cover is made of elastic and breathable fabric.

[0035] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Please see Figure 1 As shown, the purpose of this embodiment is to provide a heated inflatable lumbar pillow, including: a plurality of independent airbags 5, an isolation layer, a heating layer 3 and a controller 2 arranged sequentially in a protective cover 1;

[0037] The protective sleeve 1 is made of elastic and breathable fabric, and has an internal cavity.

[0038] The multiple independent airbags 5 are stacked sequentially from bottom to top in the receiving cavity, and each airbag 5 forms an independent air chamber through a partition membrane; in this embodiment, three independent airbags 5 are stacked from bottom to top in the receiving cavity of the protective sleeve 1, and each airbag 5 forms an independent air chamber through a partition membrane.

[0039] The isolation layer is disposed between the plurality of independent airbags 5 and the heating layer 3; the isolation layer may be made of latex or cotton. In this embodiment, a cotton layer with a thickness of less than 5mm is selected to ensure flexibility while blocking heat conduction to the airbags 5, and at the same time insulating cold air, providing excellent heat preservation and heat storage effect.

[0040] The heating layer 3 includes an upper insulating layer, a carbon nanotube flexible heating film, a flexible electrical connection layer, and a lower insulating layer arranged sequentially.

[0041] The controller 2 is electrically connected to the flexible electrical connection layer and is used to adjust the heating temperature.

[0042] In this embodiment of the present invention, the heating layer 3 further includes a temperature-controlled thermistor connected to the controller 2;

[0043] The temperature-controlled thermistor is disposed between the upper flexible insulating film and the carbon nanotube flexible heating film, and is used to feed back temperature signals to the controller 2.

[0044] In this embodiment of the present invention, the controller 2 includes a temperature control module and a USB interface;

[0045] The temperature control module is electrically connected to the flexible electrical connection layer and the temperature-controlled thermistor, and is used to adjust the heating power of the carbon nanotube flexible heating film according to the corresponding temperature power level based on the temperature signal fed back by the temperature-controlled thermistor; the USB interface is used for connecting an external power source. In this embodiment, a power bank can be selected as an external mobile power source. Based on this, this application also includes a power bank pocket 4 provided on the protective case 1 to hold the power bank.

[0046] In this embodiment of the invention, each independent airbag 5 is connected to an independent inflation / deflation unit for regulating the air pressure inside the airbag 5. Specifically, the inflation / deflation unit can be an automatic inflation device, a manual inflation device, or both.

[0047] When an automatic inflation device is selected, the inflation / deflation unit includes a miniature air pump, a deflation solenoid valve, and a pressure sensor; the miniature air pump is connected to the air inlet of the corresponding airbag 5 through a first pipeline for inflating the airbag 5; the deflation solenoid valve is connected to the air outlet of the corresponding airbag 5 through a second pipeline for releasing the gas inside the airbag 5; the pressure sensor is located inside the corresponding airbag 5 for real-time detection of the air pressure inside the airbag 5.

[0048] At this time, the controller 2 also includes an air pressure control module; the air pressure control module is electrically connected to the miniature air pump and the deflation solenoid valve; the air pressure control module is communicatively connected to the air pressure sensor; the air pressure control module controls the miniature air pump or the deflation solenoid valve to start and stop according to the feedback signal from the air pressure sensor, so as to adjust the air pressure in the airbag 5 to the target value. When the user's sitting posture changes (such as leaning forward or backward), the air pressure sensor provides real-time feedback and adjusts the pressure of the corresponding area of ​​the airbag 5 to maintain the lumbar spine in a neutral position and correct poor posture.

[0049] When a manual inflation device is selected, the inflation / deflation unit is specifically a manual inflation / deflation valve. The manual inflation / deflation valve is connected to multiple independent airbags 5 via air pipes, and is used to manually adjust the inflation volume of each individual airbag 5. Specifically, the manual inflation / deflation valve includes a manual air pump, a one-way valve, and a pressure relief knob. The manual air pump is connected to the air inlet of the corresponding airbag 5 via a third pipe. The one-way valve is located on the third pipe, allowing gas to flow only from the manual air pump to the airbag 5. The pressure relief knob is located at the air outlet of the corresponding airbag 5, and can be rotated to open or close the outlet. The manual inflation / deflation valve is independent of the miniature air pump and the deflation solenoid valve. When the user presses the manual air pump, gas flows unidirectionally into the airbag 5 through the one-way valve. When the pressure relief knob is rotated to the open position, the gas inside the airbag 5 is released through the outlet. The inflation / deflation operation of the manual inflation / deflation valve does not require the intervention of the controller 2, achieving passive manual adjustment.

[0050] Choosing a passive manual pressurizer for pressurization and depressurization operations has the advantages of being easy to carry, extending equipment life, and reducing power consumption.

[0051] It is important to note that in another embodiment, the heated lumbar pillow may include both automatic and manual inflation / deflation devices, configured in parallel. The user can select between automatic and manual modes. If the user activates manual adjustment, the controller 2 suspends automatic pressure control of the airbag 5 until the manual operation ends. In environments without power (such as outdoor scenarios), the user can adjust the airbag 5 pressure via the manual inflator, eliminating the need for batteries or an air pump. When the automatic adjustment response is delayed, the user can quickly manually inflate or deflate the airbag. The manual inflator / deflation device serves as a backup to ensure basic functionality. Furthermore, manual operation allows the user to make real-time fine adjustments based on body sensation (such as applying pressure to a specific area of ​​the lower back), compensating for the mechanical nature of automatic control. This also reduces the high-frequency reliance on the micro-air pump, extending the device's lifespan and reducing power consumption.

[0052] In embodiments of this utility model, the flexible electrical connection layer is an FPC flexible circuit board or conductive copper foil; the surface of the flexible electrical connection layer is covered with an insulating coating.

[0053] In another embodiment of this utility model, the airbag 5 is ergonomically divided into a waist support area and a side wing wrapping area; the inflation pressure of the waist support area is greater than the inflation pressure of the side wing wrapping area.

[0054] This invention uses a flexible carbon nanotube heating film as its core material. It features a micron-level thickness, repeated bending capability, and low density, enabling rapid heating within 3 seconds and ensuring uniform heating over a large area. It is also machine washable. This material efficiently absorbs and emits far-infrared rays, resulting in high heating efficiency and low energy consumption. It produces a warming effect on the human body, helping to promote blood circulation, relieve muscle pain, and achieve therapeutic effects. Furthermore, this application employs multiple inflatable airbags 5 for dynamic support and adaptation. Users can automatically or manually adjust the air pressure of the airbags 5 to infinitely adjust the height of the lumbar pillow within a certain range, precisely matching different body types. This invention, through the combination of flexible carbon nanotube heating, dynamic support from multiple airbags 5, and intelligent temperature and pressure dual control technology, solves the problems of traditional lumbar pillows such as limited functionality, low safety, and poor adaptability, thus possessing both medical rehabilitation and daily health care value.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
