Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pillow technology, and in particular relates to a pure silicone foam pillow with far-infrared heating. Background Technology
[0002] With the fast pace of modern life and increasing work pressure, problems such as poor sleep quality, neck and shoulder fatigue, and poor blood circulation are becoming increasingly common. As a result, people's demand for healthy bedding is constantly rising, and functional pillows are gradually becoming a market hotspot.
[0003] Traditional pillows are mostly made of materials such as memory foam, latex, down, or polyester fiber. While they offer some support and comfort, they generally suffer from poor breathability, heat buildup, and a lack of active therapeutic functions. This is especially problematic in cold seasons or for people with chronic neck and shoulder strain, as they fail to meet the health needs for warmth, soothing, and improved blood circulation. In recent years, electrically heated pillows have emerged, using built-in heating wires or PTC heating elements for localized heating. However, most products suffer from uneven heating, low temperature control precision, and significant safety hazards (such as overheating and electrical leakage). Furthermore, the heating elements are often made of metal, which lacks flexibility, affecting the overall comfort of the pillow. In addition, some heated pillows use near-infrared or ordinary resistance heating methods, where the heat radiation wavelength does not match the human body's absorption wavelength, resulting in weak heat penetration and limited therapeutic effects.
[0004] To address these issues, we offer a pure silicone foam pillow with far-infrared heating. Utility Model Content
[0005] The purpose of this invention is to provide a pure silicone foam pillow with far-infrared heating. By embedding the heating unit between the middle foamed silicone layer and the surface dense silicone film, and using a composite thermal structure of far-infrared heating film, aluminum foil thermal conductive substrate and high thermal conductivity silicone grease, the problem of insufficient functionality of existing electric heating pillows is solved.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0024] Example
[0025] Please see Figure 1-3 This utility model relates to a pure silicone foam pillow with far-infrared heating, comprising a pillow body 100, a heating unit 200, and a control module 300. The pillow body 100 is formed by stacking multiple layers of silicone, and this multi-layer composite structure takes into account support, breathability, and surface feel. Specifically, it includes a bottom silicone pad 101, a middle foamed silicone layer 102, and a surface dense silicone film 103. The bottom silicone pad 101 has a flat structure, and its upper surface is bonded and fixed to the middle foamed silicone layer 102. The middle foamed silicone layer 102 has several through ventilation channels inside. The surface dense silicone film 103 covers the upper surface of the middle foamed silicone layer 102. The bottom silicone pad 101 adopts a flat solid silicone structure, which has good structural stability and mechanical support. The first layer, serving as the foundational load-bearing layer of the entire pillow, ensures the stable installation of the heating unit 200 and the upper structure. The middle foamed silicone layer 102 is made of lightweight microporous foamed silicone material, which has excellent elastic cushioning performance and shock absorption effect. It can effectively conform to the curves of the head and neck, improving sleep comfort. At the same time, the through-type circular ventilation channel inside can form an air convection path, enhancing the heat dissipation and breathability of the pillow, and preventing local stuffiness caused by prolonged use. The surface dense silicone film 103 covers the foamed layer, forming a dense protective layer. It not only improves the surface wear resistance and stain resistance, but also prevents liquid from penetrating into the internal heating structure. The array of raised particles on its surface can simulate massage points, slightly stimulating the scalp, promoting local blood circulation, and enhancing the comfort and health care functions.
[0026] The heating unit 200 is embedded between the intermediate foamed silicone layer 102 and the surface dense silicone film 103, and includes a far-infrared heating film 201, a thermally conductive substrate 202, and a power lead. The far-infrared heating film 201 is a rectangular thin film structure, and the thermally conductive substrate 202 is an aluminum foil layer adhered to the lower surface of the far-infrared heating film 201. One end of the power lead is connected to the electrode of the far-infrared heating film 201, and the other end extends downward through the bottom silicone pad 101 and is connected to the control module 300. The heating unit 200 adopts a composite heating structure of "far-infrared heating film 201 + thermally conductive substrate 202 + thermally conductive grease" to achieve efficient, uniform, and safe heat transfer.
[0027] The control module 300 is encapsulated on the outer side surface of the bottom silicone pad 101. The control module 300 includes a microprocessor 301, a temperature sensor 302, a power interface 303, and operation buttons 304. The probe of the temperature sensor 302 is embedded inside the middle foamed silicone layer 102 and located above the far-infrared heating film 201. The power interface 303 is connected to an external power source via a magnetic connector. The control module 300 is externally encapsulated for easy operation and maintenance, while avoiding impact on the softness of the pillow body. The microprocessor 301 collects temperature data in real time and precisely controls the heating power. The temperature sensor 302 probe, embedded inside the middle foamed silicone layer 102 and located directly above the heating film, can accurately sense temperature changes in the actual working area, achieving closed-loop temperature feedback control and preventing overheating risks. The operation buttons 304 allow users to manually adjust the heating level or switch, improving ease of use. The power interface 303 connects to an external power source via a magnetic connector, facilitating plugging and unplugging and featuring an anti-detachment function, automatically disconnecting in case of accidental pulling to ensure safety.
[0028] Specifically, multiple heating units 200 are provided, with the far-infrared heating films 201 in adjacent heating units 200 overlapping each other. The heating units 200 are connected in parallel via power leads, which can achieve zoned temperature control or overall heating, while ensuring seamless coverage of the heating area, avoiding temperature blind spots, and improving the continuity and consistency of the thermotherapy effect. The far-infrared heating film 201 emits wavelengths in the range of 5-15μm, which is close to the wavelength of human body radiation, making it easily absorbed by human tissues, producing a resonance effect, promoting cell activity, and having good physiotherapy and health care effects. Its surface resistance is 80-120Ω, ensuring stable heating under low voltage power supply, balancing energy efficiency and safety. The upper surface of the thermally conductive substrate 202 is coated with a thermally conductive silicone grease layer with a thermal conductivity of 3.5W / (m·K), which quickly and evenly diffuses the heat generated by the far-infrared heating film 201 laterally, avoiding local overheating and improving heating uniformity and thermal response speed.
[0029] The microprocessor 301 is an STM8S003F3P6. Its input terminal is connected to the temperature sensor 302 and the operation button 304, and its output terminal is connected to the power supply circuit of the far-infrared heating film 201. The temperature sensor 302 is a PT100 platinum resistance thermometer with a measurement range of -20-150℃.
[0030] Furthermore, the lower surface of the bottom silicone pad 101 is provided with anti-slip texture, which is grid-like, significantly increasing the friction between the pillow and the bed surface, preventing slippage and displacement during use, and improving stability and safety; the ventilation channel inside the middle foamed silicone layer 102 has a circular cross-section and an axial length consistent with the length of the pillow body 100, forming a longitudinal ventilation path, which is conducive to heat dissipation and air circulation, and avoids heat accumulation leading to local high temperature or discomfort; the surface dense silicone film 103 has an array of raised particles on its surface, providing tactile massage while also helping to reduce the large area of skin contact with the pillow, further improving breathability; the pillow body 100 is covered with an outer protective cover 400, which is made of elastic knitted fabric, and the inner surface of the outer protective cover 400 has several positioning protrusions to achieve precise positioning and anti-displacement of the cover and the pillow body 100, ensuring a neat appearance and stable function.
[0031] The operation process of this embodiment is as follows: First, place the pillow stably on the bed or sleeping position, ensuring that the anti-slip texture on the lower surface of its bottom silicone pad 101 is in full contact with the bed surface to prevent slipping during use; then, put the outer protective cover 400 on the outside of the pillow body 100, and use the positioning protrusions on the inner surface of the cover to cooperate with the surface structure of the pillow body 100 to achieve precise positioning and prevent the outer protective cover 400 from shifting, ensuring a neat appearance and comfortable use; before use, check the connection status of the power lead and the control module 300, and after confirming that there is no damage or abnormality, connect one end of the magnetic connector wire to the power interface 303 on the control module 300, and connect the other end to the appropriate low-voltage DC external power supply;
[0032] After being powered on, the heating function is activated by operating button 304. The microprocessor 301 starts working according to the preset program. Users can select different heating levels according to their personal needs. The control module 300 then outputs the corresponding voltage to the far-infrared heating film 201. After being powered on, the heating film quickly generates far-infrared thermal radiation with a wavelength of 5–15μm. The heat is quickly and evenly conducted to the entire heating area through the thermally conductive substrate 202 and the thermally conductive silicone grease layer, and released to the head and neck area of the human body by the dense silicone film 103 on the surface, realizing gentle heat therapy.
[0033] During the heating process, the PT100 temperature sensor 302 embedded in the middle foaming layer continuously monitors the actual temperature and feeds the data back to the microprocessor 301 in real time. The system then automatically adjusts the heating power to maintain the temperature within the set range and prevent overheating.
[0034] After use, turn off the heating function by pressing button 304, unplug the magnetic power cord (the magnetic design automatically disconnects when pulled to ensure safety), and wait for the pillow to cool down before continuing normal use or cleaning and maintenance.
