[0028] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0029] See attached Figures 1 to 3 , a lumbar pillow, comprising: a pillow core 100, an airbag 210 and a pillowcase 300.

[0030] Among them, the pillow core 100 includes a main pillow body 110, pillow wings 120 symmetrically arranged on both sides of the main pillow body 110, and a receiving groove 130 arranged at the center position of the main pillow body 110; the airbag 210 is arranged inside the receiving groove 130; a functional accessory 320 is configured in the area corresponding to the receiving groove 130 on the inner side of the pillowcase 300, and the pillowcase 300 is mounted on the outside of the pillow core 100 and the airbag 210 to fix the airbag 210 and the functional accessory 320 in the receiving groove 130 of the pillow core 100.

[0031] It is understandable that the shape of the pillow core 100 determines the shape of the entire lumbar pillow. In this embodiment, the pillow wings 120 are symmetrically arranged on both sides of the main pillow body 110 to increase the support range, maintain the stability of the lumbar spine and reduce the uneven pressure distribution caused by lateral deviation. The accommodating groove 130 arranged in the center of the main pillow body 110 provides an installation space for the built-in airbag 210. The inflation or deflation of the airbag 210 can flexibly adapt to the body curves of different users, thereby increasing the comfort and adaptability of use.

[0032] In a further embodiment, the airbag 210 is connected with a ventilation line 220, and the ventilation line 220 passes through the pillow core 100 and the pillowcase 300 and extends to the outside of the pillowcase 300, and is connected with the inflatable device 230, and the inflatable device 230 is an inflatable balloon. The user only needs to manually squeeze the balloon to inflate the airbag 210 of the lumbar pillow, and vice versa, and deflate the air through the valve on the inflatable balloon to adjust the comfort and support effect of the lumbar pillow, so as to achieve a high degree of personalized adaptation.

[0033] In a further embodiment, in a natural state, the pillow core 100 has a constant shape, and the pillow core 100 bends inwardly toward the waist to form an arc surface. In other words, the pillow core 100 maintains a fixed structural form without external force, ensuring the consistency and stability of the shape of the lumbar pillow before and after use, so that the user can obtain similar support effects and comfort each time they use it, which is conducive to establishing a stable support memory. Moreover, the lumbar pillow is designed to be an arc surface that bends inwardly toward the waist, which can perfectly fit and support this physiological structure, help maintain the natural curve of the lumbar spine, and reduce the risk of lumbar spine pressure concentration and deformation caused by improper sitting posture for a long time.

[0034] In a further embodiment, the lower part of the pillow wing 120 and the lower surface of the main pillow body 110 form a first curve A that opens downwards; it can well adapt to and fit the hip curve, prevent the waist pillow from sliding easily during use, and maintain a stable position. The distance from the lower surface of the main pillow body 110 to the bottom of the pillow wing 120 is 6 to 15 cm, preferably 8 to 10 cm, which can ensure effective support without causing a sense of oppression to the user, and is suitable for the needs of most people.

[0035] In a further embodiment, the upper part of the pillow wing 120 and the upper surface of the main pillow body 110 form a second curve B that opens upwards, which is used to fill the gap between the seat back and the upper end of the user's back to avoid local pressure concentration, especially in the area above the waist close to the ribs, thereby improving the comfort and correctness of the sitting posture. The distance from the upper surface of the main pillow body 110 to the upper part of the pillow wing 120 is 3 to 10 cm, preferably 5 to 8 cm, ensuring that it does not cause a sense of oppression to the user's breathing or chest, and can provide sufficient support to maintain a good sitting posture.

[0036] In a further embodiment, the area of ​​the pillowcase 300 corresponding to the receiving groove 130 is provided with a functional accessory 320. The functional accessory 320 includes but is not limited to one or a combination of infrared therapy equipment, heating equipment, external application medicine bag, and massage therapy equipment, so that the waist pillow has more health care and therapy functions. Since the functional accessory 320 is directly opposite to the airbag 210, the airbag 210 can improve the fit between the functional accessory 320 and the waist, thereby better exerting the therapy effect of the functional accessory 320 and meeting the health needs of the user.

[0037] In a further embodiment, a hollow area 310 is provided on the pillowcase 300, and the functional accessory 320 is installed in the hollow area 310 of the pillowcase 300 in a detachable manner. The detachable installation method can be a Velcro provided around the hollow area 310 to achieve the installation of the functional accessory 320. The user can choose different physical therapy methods according to needs without having to purchase multiple lumbar pillows. In this embodiment, a preferred implementation is given, and the functional accessory 320 includes: a medicinal material bag, and an infrared emitting device built into the inside of the medicinal material bag or attached to the outside of the medicinal material bag. Near-infrared light waves match the radiation of the human body, which can produce a warming effect, cause vasodilation, accelerate blood flow, improve local blood circulation, and promote the absorption of Chinese medicinal materials by the human body. Moreover, near-infrared light waves can have a certain heating effect on medicinal materials, accelerate the release of medicinal materials, and can further promote the absorption of Chinese medicinal materials by the human body, and have a certain therapeutic and relieving effect on various types of joint pain, joint swelling, and chronic pain.

[0038] In a further embodiment, the functional accessory 320 extends through the pillow core 100 and the pillowcase 300 to the outside of the pillowcase 300 and is connected to the power supply and controller 340 through the line 330. Not only can the user's operation and control be convenient, but also by moving the power supply and controller 340 to the outside, the overall feeling of the lumbar pillow can be made softer and more uniform, and there will be no foreign body feeling or discomfort when using it, ensuring the experience.

[0039] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
