Description

Technical Field

[0001] This utility model relates to a cervical traction device. Background Technology

[0002] In the current cervical traction device market, although various designs have attempted to meet users' personalized needs for traction force, angle, and comfort, most products still rely on manual adjustment or preset fixed modes. This traditional approach is not only cumbersome to operate and difficult to precisely match each user's unique needs, but also often requires users to reset traction parameters after multiple uses, lacking a convenient memory function. Furthermore, with technological advancements and the increasing demand for smart health products, traditional cervical traction devices can no longer meet the market's expectations for intelligence, personalization, and convenience.

[0003] Especially in the field of medical rehabilitation, precise traction parameters are crucial for treatment effectiveness. However, most existing cervical traction devices lack intelligent control systems and cannot automatically record and restore the user's specific traction state, which to some extent limits the effectiveness of treatment and user comfort. Therefore, developing a cervical traction device that can intelligently remember the user's traction preferences and automatically restore to the optimal traction state each time it is used is key to overcoming the limitations of existing technology and improving the user experience.

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] In the description of this invention, terms such as "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 7As shown, this embodiment provides a cervical traction device, including a housing 1, a lifting frame 2, an airbag 3, an air pump 4, an air valve 5, and a PCB board 6. The PCB board 6 is connected to the air pump 4 and the air valve 5. The housing 1 is positioned below the user's chin. The housing 1 has a guide rail hole 11, and the lifting frame 2 is movably installed in the guide rail hole 11 of the housing 1. The air pump 4 is connected to the airbag 3 through the air valve 5. The airbag 3, fixedly installed in the housing 1, is raised and lowered by inflating and deflating to push against the lifting frame 2 and position the user's chin. It also includes a positioning device 14, which controls the inflation of the airbag 3 to control the position of the lifting frame 2. The positioning device 14 records and automatically restores the previous inflation state of the airbag 3, avoiding the tedious process of manually adjusting the traction height each time the user uses it. It automatically reaches the preset inflation traction state upon startup, reducing the difficulty of operation and making it suitable for users of different ages.

[0022] Furthermore, the positioning device 14 includes a timer for measuring the inflation time of the air pump 4. The PCB board 6 stores the previous inflation time of the air pump 4. When the cervical traction device is turned off and restarted, the PCB board 6 opens the air valve 5 and repeats the previous inflation time of the air pump 4, so that the airbag 3 returns to the previous inflation state and then closes the air valve 5, thereby realizing the memory of the previous working position of the lifting frame 2.

[0023] Furthermore, the lifting frame 2 has a lower jaw support plate 21, and a guide post 22 corresponding to the guide rail hole 11 is provided below the lower jaw support plate 21. The guide post 22 is inserted into the guide rail hole 11 and moves up and down.

[0024] Furthermore, it also includes a limiting piece 23 installed on the guide post 22. Since the limiting piece 23 cannot pass through the guide rail hole 11 when it is installed on the guide post 22, it prevents the lifting frame 2 from detaching from the housing 1.

[0025] Furthermore, it also includes a support sponge 24, which is disposed on the jaw support 21 and forms a cushion between the jaw support 21 and the user's jaw.

[0026] Furthermore, it also includes a check valve 7, which is located at the air inlet of the air pump 4 to prevent gas backflow.

[0027] Furthermore, it also includes a filter 8, which is connected to the check valve 7 to prevent the intake of hair or debris from causing blockage.

[0028] Furthermore, it also includes a heating element 9, which is disposed inside the housing 1. When the heating element 9 is working, it heats up and comes into thermal contact with the user, promoting the user's blood circulation.

[0029] Furthermore, it also includes a sponge cover 12 covering the shell 1. The sponge cover 12 comes into contact with the user and can undergo elastic deformation to adapt to different body shape needs and improve the user experience.

[0030] Furthermore, it also includes a lifting frame outer cover 25 disposed on the housing 1 to eliminate external interference with the internal structure of the cervical traction device.

[0031] Furthermore, it also includes a neck strap 13 connected to the housing 1, the neck strap 13 wraps around the back of the user's neck and has Velcro for fastening, so that the cervical traction device is fixed to the user's neck.

[0032] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
