[0024] like Figure 2 , Figure 3 , Figure 6 and Fig. 9 As shown, a guide assembly for guiding the connecting rod 57 to perform arc motion is provided in the operating chamber 21, and the guide assembly includes a connecting plate 71 fixedly connected to the outer wall of the pressing roller 58 symmetrically, and the end of the connecting plate 71 is set to a T-shape. A symmetrical stabilizing groove 72 is provided on the inner surface of the operating chamber 21, and two guide plates 73 are symmetrically connected to slide up and down inside the operating chamber 21. A stabilizing block 74 is symmetrically fixedly connected to the side of the guide plate 73 close to the inner surface of the operating chamber 21, and the stabilizing block 74 slides in the stabilizing groove 72 to enable the guide plate 73 to slide stably and parallelly in the operating chamber 21. A guiding arc groove 75 is provided on the guide plate 73.

Figure 6As shown, the vertical rod end of the slide rod 56 slides in the corresponding guide arc groove 75, a connecting groove 76 is provided on the guide plate 73, the end of the connecting plate 71 slides in the connecting groove 76, the connecting groove 76 is set to be compatible with the end of the connecting plate 71, the end of the connecting plate 71 slides in the connecting groove 76, and the T-shaped design prevents the connecting plate 71 from detaching from the connecting groove 76 when the guide plate 73 moves.

[0025] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: the pressing roller 58 and the sponge pad 22 are only in a contact state, the spring 1 63 is in a state of not being stretched by the pushing rod 64, and the spring 2 610 is in a state of not being compressed by the pressing rod 611.

[0026] The working status is: The user places the front piece 1 of the neck support under the chin, and then places the back piece 2 of the neck support at the back of the head, and fits the sponge pad 22 to the back of the neck, and finally fits the Velcro 3 on the back piece 2 of the neck support to the front piece 1 of the neck support, so that the front piece 1 of the neck support and the back piece 2 of the neck support are combined to support the head of the user.

[0027] Press the heating element to apply heat to the back of the user's neck: The controller starts the heating wire 59, so that the heating wire 59 is powered on and heated. After the heating wire 59 is heated, it can heat the sponge pad 22. Because the sponge pad 22 fits against the back of the user's neck, after the sponge pad 22 is heated, it can perform hot compress on the back of the user's neck. The hot compress can relieve the strain of the neck muscles and ligaments, and relieve the soreness, stiffness, and limited neck movement of the user's neck soft components.

[0028] In addition, the controller first controls the micro motor 41 to rotate forward. After the micro motor 41 rotates forward, its output shaft drives the transmission roller 42 to rotate. The transmission roller 42 drives the threaded rod 52 to rotate. The threaded rod 52 drives the moving block 53 to slide leftward on the guide rod 51 through the threaded hole. When the moving block 53 moves to the leftmost side, that is, Figure 3In the upper left corner shown, the controller controls the micro motor 41 to reverse, and the reversal of the micro motor 41 causes the threaded rod 52 to reverse. After the threaded rod 52 reverses, it drives the moving block 53 to slide rightward on the guide rod 51 through the threaded hole, and reciprocates in this way, so that the moving block 53 reciprocates back and forth. The movement of the moving block 53 drives the adjustment frame 54 to move synchronously, and the adjustment frame 54 drives the sliding rod 56 sliding on the sliding hole 55 to move synchronously. The sliding rod 56 drives the pressing roller 58 to move synchronously through the connecting rod 57. Because the pressing roller 58 is in contact with the sponge pad 22, the pressing roller 58 rotates on the connecting rod 57 through friction with the sponge pad 22 when moving. When the adjustment frame 54 moves, it will drive the slide bar 56 to slide in the guide arc groove 75. Because the shape of the guide arc groove 75 is the same as the shape of the sponge pad 22, the slide bar 56 slides in the slide hole 55 under the guidance of the guide arc groove 75. The movement of the slide bar 56 enables the connecting rod 57 to drive the pressing roller 58 to always fit with the sponge pad 22. The pressing roller 58 cooperates with the heating wire 59 to fit the sponge pad 22 for moving and heating, thereby achieving uniform heating of the sponge pad 22, which can avoid the risk of scalding to the user caused by long-term fixed position heating. The mobile heating can make the back of the user's neck evenly heated, thereby improving the effect of relieving the strain of the user's neck muscles and ligaments.

[0029] The ventilation assembly provides ventilation between the sponge pad 22 and the back of the user's neck: The output shaft of the micro motor 41 drives the transmission roller 42 to rotate during the rotation process. When the transmission roller 42 rotates, the transmission shaft 46 is driven to rotate through the transmission belt 48. The transmission shaft 46 drives the fan blades 47 to rotate. During the rotation process of the fan blades 47 on one side, air is blown, so that the airflow from the outside flows from the air inlet 44 into the air inlet cavity, and then flows from the air inlet cavity into the air outlet shell 45. Finally, the airflow flows from the air outlet hole of the air outlet shell 45 to between the sponge pad 22 and the back of the user's neck. During the rotation process of the fan blades 47 on the other side, air is drawn, so that the sponge pad 22 The hot air flow between the user's back neck flows from the air outlet to the air outlet shell 45. One side can blow external air into the space between the user and the sponge pad 22 for air drying, and the other side can draw out the hot air flow between the user and the sponge pad 22. The sponge pad 22 is a low-density sponge with relatively large pores. Therefore, the air blown out by the rotating fan blades 47 can more easily circulate therein, thereby improving the heat dissipation effect and reducing the stuffiness and sweating on the back of the user's neck when applying hot compress to the back of the neck for a long time, which may cause sweat stains to be contaminated on the neck support and breed bacteria, thereby improving the comfort of the user when applying hot compress.

[0030] During the forward and reverse switching process of the micro motor 41, the blowing and exhausting can also be switched, so that the back of the user's neck and the left and right sides of the sponge pad 22 can be blown and exhausted. The left and right sides of the back of the user's neck can be dried by blowing and exhausting back and forth, avoiding sweating that affects the hot compress effect.

[0031] In addition, when the heating wire 59 is not started, the above-mentioned airflow flows back and forth, which can alleviate the sweating problem caused by long-term wearing, reduce the stuffiness after wearing the front piece 1 and the back piece 2 of the neck support for a long time, and improve the comfort after long-term wearing.

[0032] Adjust the component so that the pressing heating component massages the back of the user's neck: The micro motor 41 is turned off, and the user holds the handle 68 and presses the pressing rod 611, so that the pressing rod 611 moves in the adjusting chamber 69 toward the side close to the adjusting frame 54, that is, Figure 8 As shown, the pressing rod 611 compresses the spring 2 610 in the adjusting chamber 69, and the movement of the pressing rod 611 drives the pushing frame 612 to move toward the adjusting frame 54 at the same time. The inclined rod on the end of the pushing frame 612 pushes the inclined surface of the pushing block 65, so that the pushing block 65 moves away from the moving block 53, that is, Figure 7 As shown, during the movement of the pushing block 65, the pushing rod 64 moves synchronously and stretches the spring 1 63, and the pushing block 65 synchronously drives the tooth block 66 to disengage from the engagement relationship with the tooth groove 61. At this time, the user can push the handle 68, so that the handle 68 drives the adjustment frame 54 to slide on the moving block 53 toward one side of the sponge pad 22, that is, Figure 5 and Figure 6As shown, in addition, during the movement of the handle 68, the connecting plate 71 is driven to move synchronously, and the connecting plate 71 drives the guide plate 73 to move synchronously toward the sponge pad 22 through the connecting groove 76, and the guide plate 73 drives the stabilizing block 74 to slide horizontally in the stabilizing groove 72. Because the guide plate 73 and the adjustment frame 54 move synchronously, the guiding arc groove 75 drives the slide bar 56 to move synchronously. When the slide bar 56 moves, it drives the pressing roller 58 to fit with the sponge pad 22 through the connecting rod 57 and push the sponge pad 22. When the position is adjusted, use The user can release the pressing rod 611, and under the elastic return action of the second spring 610, the pressing rod 611 moves to the side away from the adjusting frame 54, and the pressing rod 611 drives the inclined rod on the pushing frame 612 to no longer push the pushing block 65. At this time, under the elastic return action of the first spring 63, the pushing rod 64 drives the pushing block 65 to approach the moving block 53, and the pushing block 65 drives the tooth block 66 to engage with the corresponding tooth groove 61 again, so that the adjusting frame 54 cannot slide on the moving block 53. At this time, the controller can be used to start the micro- The micro motor 41 is configured such that the output shaft of the micro motor 41 drives the threaded rod 52 to rotate through the transmission roller 42, and the threaded rod 52 drives the moving block 53 to slide on the guide rod 51, so that the moving block 53 drives the adjusting frame 54 to move back and forth, and the adjusting frame 54 drives the sliding rod 56 to move back and forth synchronously through the sliding hole 55, and the sliding rod 56 drives the pressing roller 58 to roll back and forth on the sponge pad 22 through the connecting rod 57. In the process of the pressing roller 58 rotating and rolling, the protruding part of the convex plate 510 intermittently squeezes the sponge pad 22, and the convex plate 510 The squeezing of the sponge pad 22 can act on the back of the user's neck, and with the guidance of the slide bar 56 in the guide arc groove 75, the slide bar 56 will make the pressing roller 58 always roll back and forth on the sponge pad 22. The pressing roller 58 allows the convex plate 510 to evenly massage the back of the user's neck, thereby achieving the effects of invigorating blood circulation, relaxing muscles and bones, and relieving fatigue of the back of the user's neck. In addition, the heating wire 59 can be started by the controller, and the heating of the convex plate 510 and the heating wire 59 can further relieve the muscle stiffness of the user's neck.
