Description

Technical fields:

[0001] This utility model belongs to the field of daily necessities, and specifically relates to a cervical spine massager. Background technology:

[0002] Most cervical traction pillows on the market currently use airbags to push the pillow upwards, achieving a traction and stretching effect on the cervical spine through repeated lifting movements. However, while this repetitive, single upward movement does provide traction, it can also cause muscle and ligament fatigue and damage, significantly reducing the traction effect. For example:

[0003] CN201921818771.6 discloses a therapeutic neck pillow, comprising: a shell; a massage body disposed on the shell for massaging the head and neck of a human body; a first massage device fixedly installed within the shell for driving the massage body to swing relative to the shell to stretch and massage the head and neck of the human body, namely a rocker mechanism composed of a first airbag and a spring, responsible for the reciprocating motion of the pitch angle; and a second massage device fixedly installed within the shell for driving the shell to move up and down to correct the cervical spine, namely a second airbag responsible for the lifting and lowering motion. Both techniques involve movements on the central axis of the human body.

[0004] CN202223197646.2 discloses a neck massager, including a massager housing, an airbag massage assembly, a head support, and an inflation / deflation mechanism. The inflation / deflation mechanism includes a control module and an air pump connected to the airbag massage assembly. The massager housing includes an upper neck traction assembly and a lower neck traction assembly connected by a seesaw mechanism. The seesaw mechanism includes an upper lifting airbag on one side and an elastic element on the other side, with the upper lifting airbag connected to the air pump.

[0039] Reference Figures 1 to 6 A cervical spine massager includes a pillow body 1, a seat body 2, and an electronic control board 3. An electric mechanism 4 is installed on the seat body 2, which drives the pillow body 1 to perform a rocking motion. The electric mechanism 4 includes a motor 41 and a reduction gear 42. The final gear of the reduction gear 42 passes through an output shaft 43, which is positioned by bearings 45 mounted on the upper shell 21 and lower shell 22. These bearings are preferably hexagonal bearings. The output shaft 43 is vertically positioned in the middle of the seat body 2, and a sloping rotating seat 44 is locked at its end. The pillow body 1 is movably mounted on the sloping rotating seat 44, which supports and drives the pillow body to perform a 360-degree rocking motion, achieving slow rocking relaxation. The start and stop of the motor 41 in the electric mechanism are controlled by the electronic control board 3 located inside the seat body 2.

[0040] As a preferred embodiment, the seat 2 includes an upper shell 21 and a lower shell 22, with an electric mechanism 4 installed between them. The inclined rotating seat 44 is locked to the end of the output shaft 43 passing through the upper shell. The pillow 1 includes a headrest 11 and a lower cover 12. A circular hole 121 is formed in the center of the lower cover 12, and a limiting pin 122 is radially arranged on the outer periphery of the circular hole 121. The pillow 1 is movably mounted on the inclined rotating seat 44 via the circular hole 121, and the limiting pin 122 is constrained in the limiting groove 211 of the upper shell 21 to prevent the pillow 1 from rotating. More specifically, the inclined rotating seat 44 is a two-body structure, including a base 441 and a seat cover 442. An outer sliding ring 443 is formed on the base 441. The pillow 1 is slidably connected to the outer sliding ring 443 via an inner sliding ring 124 formed by the edge of the circular hole 121 on the lower cover, and then locked by the seat cover 442, so that the pillow is rotatably positioned on the output shaft. The limiting pin 122 is locked onto the screw post 123 on the outer periphery of the round hole of the lower cover 12, and can be lowered to cooperate with the limiting slide groove 211. Considering the swaying amplitude of the pillow body, the lower cover 12 is hollowed out at the position corresponding to the limiting slide groove 211.

[0041] Further optimization of the shape design: the seat 2 is larger than the pillow 1, and the upper shell 21 has a recessed area 212 formed corresponding to the projection area of ​​the pillow 1, with an arched edge 213 on the outer edge; the motor 41 and the reduction transmission device 42 are respectively set within the recessed area 212 of the upper shell, and the limiting groove 211 protrudes from the surface of the recessed area 212; a position sensor 31 is also set on the recessed area 212, which faces the inclined rotating seat 44 to detect the rotational position of the inclined rotating seat 44. More specifically, the position sensor 31 is a Hall element, and a magnet 311 is embedded in the bottom of the inclined rotating seat 44, such as... Figure 6 When traction is applied or the machine is turned off, the pillow body can return to its initial equilibrium position.

[0042] In addition, an elastic connecting sleeve 5 is provided between the outer edge of the recessed area 212 of the pillow body 1 and the upper shell of the seat body to cover the swing gap of the pillow body 1, which not only improves the appearance but also prevents small objects from entering. The elastic connecting sleeve 5 is preferably a corrugated tube, with folded edges 51 formed at both ends for abutment. The upper folded edge 51 abuts against the edge of the lower cover 12 of the pillow body and is clamped and fixed by the upper pressure ring 52; the lower folded edge 51 abuts against the surface of the upper shell 21 of the seat body 2 and is pressed and fixed by the lower pressure ring 53. The elastic connecting sleeve 5 can also be made of elastic cloth, thin rubber sleeve, etc.

[0043] Furthermore, the headrest 11 of the pillow body has a headrest area 111 and a neck rest area 112 longitudinally distributed, and is inclined with the neck rest area 112 higher and the head rest area 111 lower. The neck rest area 112 conforms to the U-shaped streamlined structure of the curve of the human neck, and has protrusions 1121 on both sides in the lateral direction. It gradually narrows from the protrusions 1121 along the edge and extends to the head rest area 111. A head pressure depression area 1111 is formed on the head pressure depression area 1111, and a soft rubber pad 13 with small bumps evenly distributed on the surface is attached to the head pressure depression area 1111. The headrest has a neck pressure depression area 1122 symmetrically formed on the opposite side of the two protrusions 1121 of the neck rest area 112. A pulse electrode plate 32 is attached to the neck pressure depression area 1122, and a heating plate 33 is placed at the bottom of the pulse electrode plate 32 to reduce the cold feeling and play a heat therapy role. The pulse electrode plate 32 and the heating plate 33 are controlled by the electronic control board 3 and can be selected as needed.

[0044] As a preferred extension, a base 6 is also provided at the bottom of the seat body 2, and the airbag 61 in the base 6 provides levitation support for the seat body 2. It can adjust the height to meet the needs of different people, and can also lift to form cervical traction. The airbag 61 is connected to the air pump 7 via the solenoid valve 71. The air pump 7 and the solenoid valve 71 are controlled by the electronic control board 3 to adjust the inflation and deflation rhythm.

[0045] Furthermore, the base 6 includes a base plate 62, a connecting cover 63, a telescopic bag 64, and an airbag 61. The airbag 61 is clamped between the connecting cover 63 and the base plate 62, and the connecting cover 63 is locked to the bottom of the lower shell 22 of the base body 2. The telescopic bag 64 wraps around the base plate 62 and the airbag 61, with its edge embedded in the side groove 631 of the connecting cover, and is clamped between the connecting cover 63 and the lower shell 22 of the base body 2 during assembly. The telescopic bag 64 is made of elastic fabric, which facilitates assembly, but the above-mentioned elastic connecting sleeve 5 is also possible. The opening of the telescopic bag 64 is wrapped with a plastic ring or multiple layers of sewn fabric, which thickens it to facilitate clamping and prevent it from falling out.

[0046] Two airbags 61 are arranged side-by-side and connected to an air pump 7 via independent solenoid valves 71. This allows for independent control of the inflation and deflation of the left and right airbags. When both airbags inflate and deflate simultaneously, they can provide lifting and traction. Alternating inflation and deflation can simulate left and right stretching movements, enriching the physiotherapy methods. The air inlet 611 of the airbag faces upward. A through hole 221 is provided at the corresponding position of the connecting cover 63 and the lower shell 22 of the seat. The air inlet 611 passes through the through hole 221 and is connected to the solenoid valve 71 located on the lower shell 22 via an air tube, simplifying the function of one side of the base 6 and concentrating the assembly on one side of the seat 2. It should be noted that, in order to provide necessary positioning for the air inlet 611, a ring is formed along with the air inlet 611, and a pin 612 passing through the ring rests on the upper surface of the through hole 221.

[0047] In addition, the air pump 7 is an external design, keeping it away from operating noise. The air pump 7 is housed in the soundproof box 73 and is connected to the electronic control board 3 and solenoid valve 71 located on the lower shell 22 of the base via the pneumatic-electric composite cable 72. The remote control 34 is magnetically attached to the soundproof box 73. When in use, the remote control 34 is removed for operation. When not in use, the remote control is magnetically attached to the soundproof box 73 to prevent the remote control from being placed randomly and causing inconvenience or loss.
