[0016] The technical effects and advantages of this utility model are:

[0017] 1. By arranging a vibration motor body, an eccentric wheel, an arc-shaped blade, a fixed block, a first air duct and a second air duct, when the vibration motor body is turned on, the vibration motor body will drive the eccentric wheel to rotate through the transmission shaft, and the eccentric wheel will drive the arc-shaped blade to rotate. The heat generated by the vibration motor body due to operation will be accumulated inside the fixed box. When the solenoid valve outside the first air duct is opened and the solenoid valve outside the second air duct is closed, the rotating arc-shaped blade will drive the hot air flow inside the fixed box to flow from the first air duct to the position of the user's neck, thereby providing auxiliary heating to the user's neck, avoiding the problem that the cold touch in cold seasons causes discomfort to the user's neck, thereby improving the practicality of the device; at the same time, the second air duct can be externally connected to the outside of the massage chair.

When you need to increase the heat of the neck massage, you can turn on the heating block. The electric heating wire inside the heating block generates heat due to power. The airflow generated by the rotation of the arc-shaped blades will pass through the interior of the massage block, evenly dissipating the heat generated by the heating block and passing it to the user's neck through the heat dissipation holes, thereby facilitating the uniform guidance of the hot air and improving the user's comfort.

[0019] 3. By setting the transmission shaft, connecting sleeve, limiting block, square slot, limiting slot and fixing bolt, when the eccentric wheel and the transmission shaft need to be installed, first insert the connecting sleeve into the outside of the transmission shaft, insert the limiting block into the inside of the limiting slot, insert the square block into the inside of the square slot, and then insert the fixing bolt into the inside of the transmission shaft and the connecting sleeve to fix them. Since the limiting block and the square block can disperse the rotational force when the eccentric wheel rotates, the rotational force is prevented from directly acting on the fixing bolt. After the fixing bolt is worn, the connecting sleeve and the transmission shaft are prone to loosening, causing abnormal noise in the vibration motor body, thereby bringing convenience to the use of the vibration motor body.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides Figure 1 、 Figure 4 、 Figure 5 and Figure 7The neck control mechanism of a massage chair that can relieve cervical vertebra shown in the figure includes a vibration motor body 7, the output end of the vibration motor body 7 is fixedly installed with a transmission shaft 11, the outside of the transmission shaft 11 is plugged with a connecting sleeve 12, the side of the connecting sleeve 12 is fixedly connected with an eccentric wheel 18, the side of the eccentric wheel 18 close to the vibration motor body 7 is fixedly connected with an arc-shaped blade 17, the top of the vibration motor body 7 is fixedly connected with a fixed box 6, the vibration motor body 7 is located inside the fixed box 6, the top and bottom of the fixed box 6 are both provided with a first ventilation slot 19, the first ventilation slot 19 is located above and below the arc-shaped blade 17, the top of the fixed box 6 is fixedly connected with a first air duct 8, the bottom of the fixed box 6 is fixedly connected with a second air duct 9, the outside of the first air duct 8 and the second air duct 9 are fixedly installed with an electromagnetic valve 10, the first air duct 8 is located between the first ventilation slot 19 and the second ventilation slot 23, and the top of the first air duct 8 is fixedly connected to the bottom of the massage block 3, the top of the fixed box 6 is fixedly connected with a fixed block 5, and the top of the fixed block 5 is fixedly connected to the bottom of the massage block 3.

[0030] Among them, when the vibration motor body 7 is turned on, the vibration motor body 7 will drive the eccentric wheel 18 to rotate through the transmission shaft 11, and the eccentric wheel 18 will drive the arc blade 17 to rotate. The heat generated by the vibration motor body 7 due to operation will accumulate inside the fixed box 6. When the solenoid valve 10 outside the first air duct 8 is opened and the solenoid valve 10 outside the second air duct 9 is closed, the rotating arc blade 17 will drive the hot air flow inside the fixed box 6 to flow from the first air duct 8 to the position of the user's neck, thereby providing auxiliary heating for the user's neck, avoiding the problem of the cold touch causing discomfort to the user's neck in cold seasons, thereby improving the practicality of the device; at the same time, the second air duct 9 can be connected to the outside of the massage chair. When the solenoid valve 10 outside the second air duct 9 is opened and the solenoid valve 10 outside the first air duct 8 is closed, the heat inside the fixed box 6 will flow into the second air duct 9 as the arc blade 17 rotates, and then the second air duct 9 is discharged to the outside of the massage chair, thereby avoiding the problem of poor internal heat dissipation of the massage chair affecting the heat dissipation of the vibration motor body 7, thereby improving the heat dissipation effect of the vibration motor body 7.

[0031] Also, see Figure 6 and Figure 7The top of the transmission shaft 11 is fixedly connected to the limiting block 13, and a square slot 14 is opened inside the side of the transmission shaft 11, a limiting slot 15 is opened inside the connecting sleeve 12, and the inner wall of the connecting sleeve 12 is fixedly connected to the square block 20. The inside of the limiting slot 15 is plugged into the outside of the limiting block 13, and the outside of the square block 20 is plugged into the inside of the square slot 14. The connecting sleeve 12 and the inside of the transmission shaft 11 are plugged with a fixing bolt 16, and the external thread of the fixing bolt 16 is connected to a nut. When the eccentric wheel 18 needs to be installed with the transmission shaft 11, first insert the connecting sleeve 12 into the outside of the transmission shaft 11, so that the limit block 13 is inserted into the inside of the limit groove 15, and the square block 20 is inserted into the inside of the square slot 14, and then the fixing bolt 16 is inserted into the inside of the transmission shaft 11 and the connecting sleeve 12 to fix them. Since the limit block 13 and the square block 20 can disperse the rotational force when the eccentric wheel 18 rotates, the rotational force is prevented from directly acting on the fixing bolt 16. After the fixing bolt 16 is worn, the connecting sleeve 12 and the transmission shaft 11 are prone to loosening, causing the vibration motor body 7 to have abnormal noise problems, thereby bringing convenience to the use of the vibration motor body 7.

[0032] Next, see Figure 1 、 Figure 2 and Figure 3 A massage assembly is provided on the top of the fixed box 6. The massage assembly includes a massage block 3. A massage ball head 4 is fixedly connected to the top of the massage block 3. A heat dissipation hole 21 is provided inside the top of the massage block 3. A second ventilation slot 23 is provided at the bottom of the massage block 3. A heating block 22 is fixedly connected to the bottom of the inner cavity of the massage block 3. When the vibration motor body 7 is turned on, the vibration motor body 7 will drive the massage block 3 to vibrate, and the massage block 3 will drive the massage ball head 4 to vibrate, thereby massaging the user's neck. When it is necessary to increase the heat of the neck massage, the heating block 22 can be turned on. The heating wire inside the heating block 22 generates heat due to the power supply. As the arc-shaped blades 17 rotate, the airflow generated will pass through the interior of the massage block 3, evenly dissipating the heat generated by the heating block 22 and passing it to the user's neck from the heat dissipation hole 21, thereby facilitating the uniform guidance of the hot air and improving the user's comfort.

[0033] Finally. See Figure 1 and Figure 2The bottom of the massage block 3 is fixedly connected to a spring telescopic rod 2, the bottom end of which is fixedly connected to a mounting plate 1. A chute is provided inside the mounting plate 1, and the interior of the chute is slidably connected to the exterior of the second air duct 9. When the vibration motor body 7 is turned on, the vibration motor body 7 drives the massage block 3 to vibrate, which in turn drives the spring telescopic rod 2 to reciprocate. The spring provided inside the spring telescopic rod 2 increases the amplitude of the massage block 3, making the use of the device more convenient. Since the interior of the chute is slidably connected to the exterior of the second air duct 9, the second air duct 9 also guides the vibration direction of the massage block 3 without hindering the vibration of the massage block 3.

[0034] Working principle: First, use the mounting plate 1 to fix the entire device inside the massage chair near the user's neck. When the vibration motor body 7 is turned on, the vibration motor body 7 will drive the eccentric wheel 18 to rotate through the transmission shaft 11, and the eccentric wheel 18 will drive the arc-shaped blades 17 to rotate. The heat generated by the vibration motor body 7 due to operation will gather inside the fixed box 6. When the solenoid valve 10 outside the first air duct 8 is opened and the solenoid valve 10 outside the second air duct 9 is closed, the rotating arc-shaped blades 17 will drive the hot air flow inside the fixed box 6 to flow from the first air duct 8 to the user's neck, providing auxiliary heating for the user's neck, avoiding the problem that the cold touch in cold seasons will cause discomfort to the user's neck, thereby improving the practicality of the device; at the same time, the second air duct 9 can be connected to the outside of the massage chair. When the solenoid valve 10 outside the second air duct 9 is opened and the solenoid valve 10 outside the first air duct 8 is closed, the hot air flow inside the fixed box 6 will flow from the first air duct 8 to the user's neck, thereby providing auxiliary heating for the user's neck, thereby avoiding the problem that the cold touch in cold seasons will cause discomfort to the user's neck, thereby improving the practicality of the device. At the same time, the second air duct 9 can be connected to the outside of the massage chair. When the solenoid valve 10 is turned on, the heat inside the fixed box 6 will flow into the second air duct 9 as the curved blades 17 rotate, and the second air duct 9 is discharged to the outside of the massage chair, avoiding the problem of poor internal heat dissipation of the massage chair affecting the heat dissipation of the vibration motor body 7, thereby improving the heat dissipation effect of the vibration motor body 7. When the vibration motor body 7 is turned on, the vibration motor body 7 will drive the massage block 3 to vibrate, and the massage block 3 will drive the massage ball head 4 to vibrate, thereby massaging the user's neck. When it is necessary to increase the heat of the neck massage, the heating block 22 can be turned on. The heating wire inside the heating block 22 generates heat due to the power supply. The airflow generated by the rotation of the curved blades 17 will pass through the inside of the massage block 3, and evenly dissipate the heat generated by the heating block 22, and pass through the heat dissipation hole 21 to the user's neck, thereby facilitating the uniform guidance of the hot air and improving the user's comfort.
