[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] To provide a clearer explanation and description of the technical solution and implementation method of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0038] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.

[0039] like Figure 1 , Figure 2As shown, this utility model provides a health chair for exercising neck muscles, stretching the cervical spine, and treating cervical spondylosis, including a seat 10 and a backrest 20. A pressure arm assembly 30 is provided on at least one side of the backrest 20, with one end of the pressure arm assembly 30 rotatably mounted on the side of the backrest 20 via a pivot 40. A load assembly 50 is provided inside the backrest 20, and the pivot 40 is coupled to the load assembly 50, configured such that when the pressure arm assembly 30 is pressed down, the pivot 40 rotates, and the load assembly 50 is stretched through the pivot 40, thereby providing load resistance for the rotation of the pressure arm assembly 30.

[0040] The backrest 20 has a pressure arm storage groove 21 on its side. When the pressure arm assembly 30 is not in use, it can be stored in the pressure arm storage groove 21, keeping the side surface of the backrest 20 flat and preventing protrusions from affecting safety and aesthetics. Figure 3 As shown.

[0041] like Figure 4 , Figure 5 As shown, the pressure arm assembly 30 includes a first pressure arm 31 and a second pressure arm 32. The first end of the first pressure arm 31 is connected to the rotating shaft 40 via a sliding sleeve 33, and the first end of the second pressure arm 32 is hinged to the second end of the first pressure arm 31. By rotating the second pressure arm 32, it can be placed against the inner side of the first pressure arm 31 for storage.

[0042] To further reduce the size of the pressure arm assembly 30, a second pressure arm storage groove 21, adapted to the shape of the second pressure arm 32, is provided on the inner side of the first pressure arm 31. When the pressure arm assembly is not in use, the second pressure arm 32 can be rotated and stored in the second pressure arm storage groove 21. This design makes the pressure arm assembly more compact, effectively reducing the space occupied; at the same time, the appearance is flat and simple, enhancing the overall design aesthetics and making the product more in line with modern industrial design trends and users' aesthetic needs.

[0043] The sliding sleeve 33 is fixed on the inner side of the first end of the first pressure arm 31. The sliding sleeve 33 is fitted onto the rotating shaft 40. A keyed structure, such as a spline structure, is provided between the two to form a rotation limit pair, so that the sliding sleeve 33 can slide along the axial direction of the rotating shaft 40 and drive the rotating shaft 40 to rotate.

[0044] In addition, a shaft end limiting structure is provided between the sliding sleeve 33 and the rotating shaft 40 to prevent the pressure arm assembly 30 from falling off the rotating shaft 40 during pull-out or use. Figure 6 , Figure 7As shown, the shaft end limiting structure includes a spline groove 41 provided at the shaft end of the rotating shaft 40, and a spline 331 matching the spline groove 41 on the inner wall of the sliding sleeve 33, the length of the spline 331 being less than the length of the spline groove 41. A limiting plate 42 is fixed to the end of the rotating shaft 40 to block and limit the axial movement of the spline 331. The distance between the spline 331 and the outer end face of the sliding sleeve 33 is equal to the depth of the pressure arm storage groove 21, so that the pressure arm assembly 30 can be completely hidden in the pressure arm storage groove 21 after storage. The limiting plate 42 can be installed after the first pressure arm 31 is assembled with the rotating shaft 40. For this purpose, the outer side of the first pressure arm 31 is provided with mounting holes corresponding to the limiting plate 42, and a removable protective cover is provided.

[0045] In existing neck-strengthening chairs, the arm support assembly is usually placed against the side of the backrest after being folded and stored. This makes it easy for it to be scratched by external objects, posing a safety hazard. Furthermore, when the user sits down to rest, the arm support assembly is prone to bumping against the arm, affecting comfort.

[0046] When not in use, the pressure arm assembly can be rotated and pushed into the pressure arm storage slot 21 on the side of the backrest 20, eliminating any protruding structures on the side of the backrest 20. This effectively prevents the pressure arm assembly from being scratched by others or external objects, improving safety and reliability. Simultaneously, the pressure arm assembly 30 is completely hidden inside the backrest 20, resulting in a neat and aesthetically pleasing overall appearance and further enhancing the user experience.

[0047] In this application, the pressure arm assembly can be set into one or two sets. Figure 8 The diagram shows a set of pressure arm assemblies. Figure 1 In the health chair shown, pressure arm assemblies 30 are provided on both sides of the backrest 20. During use, the ends of the two second pressure arms 32 are connected to each other, forming a double-arm linkage structure. Compared to a single-arm structure, the double-arm structure provides symmetrical force distribution, offering more even support, thereby improving safety and comfort, and avoiding the problem of inflexible rotation of the pressure arm assembly due to uneven force distribution on a single arm.

[0048] In this application, the ends of the two second pressure arms 32 overlap and are coupled to each other, and they can be connected by magnetic attraction. Therefore, the connection and separation of the two second pressure arms 32 are simple and convenient to use. Specifically, the ends of the two second pressure arms 32 can be provided with complementary notches, and the overall thickness remains consistent after overlapping and connecting, which is both aesthetically pleasing and comfortable.

[0049] To further enhance user comfort, this application also includes a chin rest 60 with a soft pad. In use, the chin rest 60 can be installed at the end of the second pressure arm 32 (suitable for single-arm applications) or at the connection point of the two second pressure arms 32 (suitable for dual-arm applications). The user rests their chin on the chin rest 60 and applies downward pressure to operate the pressure arm assembly 30, thus achieving a comfortable experience. The chin rest 60 can be magnetically attached to the second pressure arm 32 for easy installation and removal, and can be magnetically attached to the seat when not in use.

[0050] Please see again. Figure 7 The load assembly 50 includes an upper pull arm 51, an elastic element 52, and a lower pull arm 53. The upper pull arm 51 is fixed to the middle of the rotating shaft 40, which is rotatably mounted inside the backrest 20 via a fixed seat. The lower pull arm 53 is fixed inside the backrest 20. The upper and lower ends of the elastic element 52 are connected to the upper pull arm 51 and the lower pull arm 53 respectively via connecting straps 54.

[0051] The elastic element 52 can be a tension spring or an elastic band, and one or more can be used depending on the actual needs of use. This application does not limit this.

[0052] To improve user comfort, such as Figure 1 , Figure 3 As shown, this application has a lumbar support 22 at the lower end and a neck support 23 at the upper end of the backrest 20, with both the lumbar support 22 and the neck support 23 protruding from the surface of the backrest 20. A groove 24 is provided on the surface of the backrest 20 above the neck support 23. During use, when the user leans back, their head naturally falls into the groove 24. At this time, the neck support 23 pushes forward on the cervical spine, helping to relieve cervical pressure and achieve proper cervical alignment.

[0053] The following describes the specific usage of this application.

[0054] The user first sits on the health chair and pulls the first pressure arm 31 out of the pressure arm storage slot 21. Under the action of the elastic element 52, the first pressure arm 31 will rotate upward to a roughly horizontal position. Then, the second pressure arm 32 is pulled out from the groove of the first pressure arm 31 and rotated to below the jaw so that the two second pressure arms 32 overlap each other, and then the jaw pad 60 is installed.

[0055] The user presses down on the chin-pressing arm assembly 30, causing the rotating shaft 40 to rotate. The rotation of the rotating shaft 40 causes the upper arm 51 to move upward, thereby lifting the elastic element 52 and generating resistance. Through this process, the purpose of exercising the neck muscles is achieved.

[0056] After exercising, first remove the chin pad 60, rotate the second pressure arm 32 and store it in the groove of the first pressure arm 31. Next, rotate the first pressure arm 31 downwards to fit against the side of the backrest 20, and finally push it into the pressure arm storage slot 21 on the side of the backrest 20 to complete the overall storage.

[0057] Based on the above description of specific embodiments, the health chair provided by this utility model for exercising neck muscles, stretching the cervical spine, and treating cervical spondylosis has the following advantages compared with the prior art:

[0058] First, the pressure arm assembly can be completely stored in the receiving slot on the side of the backrest when not in use, leaving the outer surface of the backrest flat and without any protrusions. This design not only effectively prevents the pressure arm assembly from being damaged by external impacts, improving safety and reliability, but also makes the overall appearance more concise and aesthetically pleasing, enhancing the user experience.

[0059] Secondly, the inner side of the first pressure arm is provided with a groove that matches the shape of the second pressure arm. When not in use, the second pressure arm can be rotated and stored in the groove, making the overall structure of the pressure arm assembly more compact and effectively saving space.

[0060] Third, a neck support is provided at the upper end of the backrest, and the backrest surface above the neck support has a groove that conforms to the contour of the head. During use, the user's head can naturally rest in the groove, while the neck support applies forward pressure, providing support and compression for the cervical spine, which helps relieve cervical fatigue and achieve natural alignment of the cervical spine.

[0061] Fourth, this application uses elastic elements such as tension springs and elastic bands to provide resistance, which is simple in structure and low in cost.

[0062] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a…" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0063] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
