On the one hand, the essential oil massage effect can be achieved during the use of the neck massager. On the other hand, the essential oil is used to absorb the heat on the surface of the electrode to reduce the continuous heating of the electrode on the massage area, ensuring that the contact surface of the skin is always at a more suitable temperature, thereby improving the comfort of the massage.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] Example 1

[0032] In order to solve the problem that the existing neck massager has poor adjustment and fixation reliability when performing bending adjustment, the following solution is disclosed. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 、 Figure 5 As shown:

[0033] A foldable neck massager comprises a neck massager body 1, both ends of the neck massager body 1 are connected to rubber sleeves 3, and one end of the rubber sleeves 3 is connected to a clamping arm 2, electrode sheets 4 are provided on both sides of the inner end surface of the neck massager body 1, arc blocks 6 are installed on the end surface of the neck massager body 1 located inside the rubber sleeves 3, and connecting blocks 9 are installed on the inner sides of the arc blocks 6, connecting shafts 10 are horizontally distributed on both sides of the connecting blocks 9, and the outer ends of the connecting shafts 10 are sleeved with rotating sleeves 8, a U-shaped connecting block 7 is fixedly connected between the two rotating sleeves 8, and the U-shaped connecting block 7 is fixedly connected to the end surface of the clamping arm 2, a slot 11 is provided on the side of the arc block 6 close to the rotating sleeve 8, and a protrusion is provided on the outer end of the rotating sleeve 8, the protrusions are distributed in an annular shape on the outside of the rotating sleeve 8, and the protrusions and the slots 11 are engaged with each other, and a limited fixing mechanism 12 is provided on the side of the arc block 6 close to the clamping arm 2 to further fix the position of the protrusion on the rotating sleeve 8;

[0034] The limiting fixing mechanism 12 includes a limiting sleeve 1201 installed on the side of the arc block 6 close to the clamping arm 2, and an inserting plate 1202 is inserted into the limiting sleeve 1201. The protrusions on the outer side of the rotating sleeve 8 are each provided with a slot 1204. The inner end of the inserting plate 1202 is inserted into the corresponding slot 1204. One side of the inserting plate 1202 abuts against one side of the arc block 6. The inserting plate 1202 and the limiting sleeve 1201 are slidably connected. An elastic plate 1203 is inserted into the limiting sleeve 1201, and one end of the elastic plate 1203 is connected to one side of the outer end of the slot 1204.

[0035] The cross section of the elastic plate 1203 is hook-shaped, and the hook end is close to the rotating sleeve 8. The angle between the elastic plate 1203 and the inserting plate 1202 is 30 degrees. The elastic plate 1203 has a certain elasticity. The neck massager body 1 pushes the inserting plate 1202 to be inserted into the slot 1204.

[0036] A guide plate 13 is mounted on the end of the inserting plate 1202 away from the slot 1204, and the guide plate 13 is perpendicular to the inserting plate 1202. The guide plate 13 is located outside the rubber sleeve 3. A pressing slide 14 is slidably connected to the outside of the arc block 6, and one side of the pressing slide 14 abuts against one side of the guide plate 13. A groove is formed on the upper end of the outer side of the pressing slide 14 to facilitate finger activation.

[0037] The sliding direction slots 1204 of the pressing slide 14 are moved in directions perpendicular to each other, and the contact surfaces of the guide plate 13 and the pressing slide 14 are inclined;

[0038] The thickness of the pressing slide 14 is three times that of the guide plate 13 . By utilizing the inclined surface, when the pressing slide 14 approaches the guide plate 13 , it pushes the guide plate 13 , causing the slot 1204 to move outward.

[0039] In this embodiment, when in use, the groove on the pressing slide 14 is pressed, so that the pressing slide 14 is squeezed close to the guide plate 13, so that the guide plate 13 moves outward under the guiding action of the inclined surface, so that the inserting plate 1202 moves synchronously, so that the hook end of the elastic plate 1203 approaches the inserting plate 1202, and then the inserting plate 1202 is separated from the slot 1204, and then the clamping arm 2 can be rotated, pushing the two clamping arms 2 inward, so that the rotating sleeve 8 is deformed under the action of the pushing force, and the protrusion on the rotating sleeve 8 is rotated to different slots 11, so as to change the bending angle between the clamping arm 2 and the neck massager body 1, so that the clamping arm 2 can fit the neck of different thicknesses for massage. When the adjustment is completed, the neck massager body 1 and the clamping arm 2 are aligned with the neck contour, so that the electrode sheet 4 overlaps the neck position, and then the groove is pressed to reset the pressing slide 14 to fix the angle of the neck massager body 1 and the clamping arm 2, thereby ensuring the stability of the neck massager during use.

[0040] Example 2

[0041] This embodiment is different from the first embodiment. The squeezing mechanism 17 is used to automatically squeeze the liquid capsule 5 during the operation of the massager, thereby realizing the automatic release of essential oil to achieve the effects of essential oil massage and essential oil cooling. Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 As shown:

[0042] The outer edge of the electrode sheet 4 is sheathed with a liquid capsule 5, and the interior of the liquid capsule 5 is filled with essential oil. The top of the liquid capsule 5 is provided with an oil inlet 16, and the interior of the oil inlet 16 is penetrated by a threaded plug. Oil outlet holes 15 are evenly opened at the upper and lower ends of the inner side of the liquid capsule 5, and an interception net is provided inside the oil outlet hole 15. A squeezing mechanism 17 is provided on the side of the electrode sheet 4 close to the neck massager body 1 to automatically squeeze the liquid capsule 5, compressing the two sides of the liquid capsule 5 inward, so that the essential oil is discharged from the oil outlet hole 15;

[0043] The squeezing mechanism 17 includes two isolation tubes 1701, which are respectively installed on the side of the electrode sheet 4 near the neck massager body 1 and are horizontally distributed in an upper and lower direction. A heat conductive block 1705 is installed in the center of the isolation tube 1701. Memory metal 1704 is installed on both sides of the heat conductive block 1705. One end of each memory metal 1704 is connected to a metal wire 1702. The outer end of each metal wire 1702 extends to the outside of the isolation tube 1701. The outer ends of the upper and lower metal wires 1702 on the same side are commonly connected to an extrusion plate 1703. The inner side of the extrusion plate 1703 is connected to the outer edge of the liquid capsule 5.

[0044] There are two groups of extrusion plates 1703, each group having two extrusion plates. The extrusion plates 1703 are arc-shaped, and the width of the metal wire 1702 is greater than the width of the liquid capsule 5.

[0045] The memory metal 1704 is a nickel-titanium memory alloy. When the electrode sheet 4 is heated during operation, the memory metal 1704 returns from a straightened state to a bent and shortened memory state.

[0046] In this embodiment, the neck massager is started during use, and electric current is used to stimulate the contact surface between the electrode sheet 4 and the neck to achieve a massage effect. As the use time continues, the electrode sheet 4 generates a certain amount of heat due to the continuation of the current. When a specific temperature is reached, the memory metal 1704 generates a memory reset, shortening the memory metal 1704, and then one end of the memory metal 1704 generates a sudden inward pulling force on the metal wire 1702, and then the two extrusion plates 1703 are squeezed inward, causing the liquid capsule 5 to deform, so that the essential oil flows out from the oil outlet 15. The essential oil is used to promote the skin's absorption of the essential oil during massage, thereby improving the comfort of massage. At the same time, the essential oil is used to absorb the heat on the electrode sheet 4, so as to avoid overheating and burning the skin on the surface of the electrode sheet 4, further improving the comfort of massage.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
