[0034] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0035] Such as Figures 1 to 6As shown in the figure, this embodiment provides a head massager, which includes a housing, a transmission assembly, and a plurality of massage heads 1. The massage heads 1 are arranged outside the housing, and a part of the transmission assembly extends out of the housing. The transmission assembly is used to drive the massage heads 1 to swing. The transmission assembly includes a gear set 4, a driving unit 6, and a plurality of rocker arm assemblies 2. The driving unit 6 is used to drive the gear set 4 to rotate, and the number of rocker arm assemblies 2 is the same as that of the massage heads 1. The rocker arm assembly 2 includes a rocker arm body 21 and a sliding member 23 hinged to one end of the rocker arm body 21. The rocker arm body 21 passes through and is hinged to the housing, and a massage head 1 is fixedly connected to the other end of each rocker arm body 21. The gear set 4 includes a driving gear 43 rotatably connected to the housing, and the number of driving gears 43 is the same as that of the rocker arm assemblies 2. An irregular groove 431 is provided on one end face of the driving gear 43, and a sliding member 23 is provided in each irregular groove 431. The side wall of the sliding member 23 is at least partially in contact with and slidably engaged with the groove wall of the irregular groove 431, so that the sliding member 23 reciprocates in a linear direction. The axis of the driving gear 43 and the length direction of the rocker arm body 21 are in the same plane.

[0036] The head massager adopts the design of driving the rocker arm body 21 by the driving gear 43, so that the driving unit 6 can drive the massage heads 1 to make a reciprocating swinging head-shaking motion through the precise transmission of the gear set 4 and the rocker arm assembly 2. The head-shaking motion of the massage heads 1 can simulate the scratching of the scalp by human hands and improve the user experience. Among them, the design of the rocker arm body 21 hinged to the housing and the sliding member 23 hinged to one end of the rocker arm body 21 can be combined with the limitation that the axis of the driving gear 43 and the length direction of the rocker arm body 21 are in the same plane, so that the groove wall of the irregular groove 431 drives the rocker arm body 21 to make a regular reciprocating swing in a linear direction by pushing the sliding member 23. The above transmission structure effectively reduces the friction between the driving gear 43 and the sliding member 23, reduces the power loss during the transmission process, and avoids the situation of the rocker arm assembly 2 being stuck due to force, which helps to realize the large-force massage action of the massage heads 1. At the same time, the housing provides effective protection for the transmission assembly; the design of multiple driving gears 43 and multiple rocker arm assemblies 2 realizes the simultaneous driving of multiple massage heads 1 by the driving unit 6, improves the working efficiency, and helps to plan the movement rules of all massage heads 1 and realize the synchronous control of all massage heads 1. The above improvements optimize the movement trajectory of the massage heads 1, improve the massage strength and comfort of the head massager, and enhance the massage effect of the head massage.

[0037] In this embodiment, the sliding member 23 includes a swing tube 232 and two limit protrusions 231 fixedly connected to the outer side wall of the swing tube 232. The two limit protrusions 231 are symmetrically arranged about the axis of the swing tube 232. One end of the rocker main body 21 is placed inside the swing tube 232. The pin 22 passes through the swing tube 232 and is hinged to the rocker main body 21, so that the rocker main body 21 swings along the axis of the pin 22. The axis of the pin 22 is perpendicular to the axis of the swing tube 232, and the axis of the pin 22 is perpendicular to the length direction of the limit protrusion 231.

[0038] The rocker main body 21 and the sliding member 23 are hinged and matched through the pin 22, so that the rocker main body 21 can swing along the axis of the pin 22, and the sliding member 23 can reciprocate in a straight line direction.

[0039] By limiting the positions of the swing tube 232 and the two limit protrusions 231, the contact positions between the sliding member 23 and the groove walls of the special-shaped groove 431 are planned. At the same time, the production cost of the sliding member 23 is reduced, and the space occupied by the sliding member 23 is reduced. By restricting the position of the axis of the pin 22, the force-bearing condition of the rocker assembly 2 is improved, the risk of damage to the rocker assembly 2 is reduced, and the specific structure of the rocker assembly 2 is simplified. Thus, it is ensured that the rocker assembly 2 completes the predetermined action according to the rule, avoiding the situation of jamming of the rocker assembly 2 and ensuring the smooth driving of the massage head 1. At the same time, the design of the hinged cooperation using the pin 22 is simple and reliable, with a long service life, high working stability and small occupied space.

[0040] When assembling the rocker assembly 2, one end of the rocker main body 21 is extended into the swing tube 232, and the pin 22 passes through the sliding member 23 and the rocker main body 21, so that the rocker main body 21 is hinged to the sliding member 23. The outer diameter of the pin 22 is smaller than the aperture of the opening on the rocker main body 21, so the rocker main body 21 can make relative movement with the swing of the sliding member 23.

[0041] As Figures 5 to 10 shown, the projection of the special-shaped groove 431 in the plane perpendicular to the depth direction of the special-shaped groove 431 is in a three-leaf shape, and the special-shaped groove 431 is coaxial with the driving gear 43. The projection of the sliding member 23 in the plane perpendicular to the height direction of the sliding member 23 is in a spindle shape. The above structural limitations realize the shape limitations of the special-shaped groove 431 and the sliding member 23, achieving the purpose of optimizing the movement track of the rocker main body 21, limiting the movement space of the rocker assembly 2, thereby improving the transmission mode between the gear set 4 and the rocker assembly 2 and simplifying the specific structure of the head massager.

[0042] Exemplarily, three sub-grooves are formed in the groove wall of the special-shaped groove 431. The three sub-grooves are evenly distributed along the rotation center of the driving gear 43, and the shape of the sub-grooves is U-shaped. Specifically, the three sub-grooves are distributed at 120° intervals from each other. The above shape definition details the specific structure of the special-shaped groove 431, ensures the smooth cooperation between the sliding member 23 and the special-shaped groove 431, and guarantees the long-term stable operation of the head massager.

[0043] Furthermore, the ends of the two limiting protrusions 231 are always in contact with the groove wall of the special-shaped groove 431, and the outer side wall of the swing tube 232 is always partially attached to the groove wall of the special-shaped groove 431. The above definition realizes the precise cooperation between the driving gear 43 and the sliding member 23, reduces the risk of the sliding member 23 shifting in position accidentally, and guarantees the long-term stable transmission between the gear set 4 and the rocker assembly 2. At the same time, the above improvements also contribute to optimizing the structural layout of the gear set 4 and the rocker assembly 2, facilitating the reduction of the space occupied by the head massager, and helping to achieve the structural optimization of the head massager.

[0044] In this embodiment, shell through-holes 31 are formed in the housing. The number of shell through-holes 31 is the same as that of the rocker main bodies 21. A guiding shaft 32 protrudes from the inner wall of each shell through-hole 31. The middle part of each rocker main body 21 passes through a shell through-hole 31 and is hinged to a guiding shaft 32, enabling the rocker main body 21 to swing along the axis of the guiding shaft 32.

[0045] The provision of the shell through-holes 31 and the guiding shafts 32 realizes the hinged connection between the housing and the rocker main bodies 21, ensuring that the rocker main bodies 21 can swing smoothly along the axis of the guiding shafts 32. The above design is simple and reliable, occupies a small space, and has high connection stability, guaranteeing the long-term stable operation of the rocker assembly 2.

[0046] Continuing to refer to Figures 1 to 6 , the housing includes a housing cover 3 and a housing base 5 detachably connected to the housing cover 3. The shell through-holes 31 are formed in the housing cover 3. The driving unit 6 is detachably connected to the housing base 5. A plurality of rotating shafts are fixedly connected to the housing base 5. The gear set 4 is rotationally connected to the housing base 5 through the rotating shafts. The length direction of the rotating shafts is parallel to the output shaft of the driving unit 6.

[0047] The provision of the housing cover 3 and the housing base 5 realizes the split design of the housing, reduces the production cost of the housing, and lowers the assembly difficulty of the head massager; combined with the definition that the shell through-holes 31 are formed in the housing cover 3 and the driving unit 6 and the gear set 4 are installed in the housing base 5, the optimized structural design of the head massager is realized; and the definition that the length direction of the rotating shafts is parallel to the output shaft of the driving unit 6 guarantees the transmission effect of the gear set 4, simplifies the specific structure of the gear set 4, reduces the space occupied by the gear set 4 in the housing, and helps to achieve the lightweight design of the head massager.

[0048] In this embodiment, the driving unit 6 and the gear set 4 are installed inside the housing. After connecting the sliding member 23 and the rocker main body 21 with the pin 22, they are installed in the driving gear 43. Then, the housing cover 3 is put on, and finally all the massage heads 1 are installed. Specifically, the driving unit 6 is a motor.

[0049] Exemplarily, the head massager further includes a battery and a key. The battery is installed inside the housing, and the key is used to control the on-off between the battery and the driving unit 6. Turning on the key enables the battery to make the motor work through the main board. The motor drives the gear set 4 to rotate. When the driving gear 43 rotates, the rocker main body 21 makes a reciprocating left-right swinging motion. At this time, the rocker main body 21 drives the massage head 1 to make a reciprocating left-right swinging motion. Turning off the key cuts off the power supply of the motor, and at this time, the gear set 4, the rocker assembly 2, and the massage head 1 stop moving.

[0050] In an implementation manner of this embodiment, the gear set 4 further includes a driving gear 41 and a double gear 42. The number of double gears 42 is the same as and corresponds one-to-one with the number of driving gears 43. The output shaft of the driving unit 6 is coaxially fixed to the driving gear 41. The driving unit 6 is used to drive the driving gear 41 to rotate along its own axis. The driven tooth parts of all the double gears 42 are engaged with the driving gear 41, and the driving tooth part of each double gear 42 is engaged with a driving gear 43. Specifically, the number of driving gears 43 is four.

[0051] By setting the driving gear 41 and the double gear 42, the transmission purpose of the gear set 4 is achieved, the precise drive of the driving unit 6 to each driving gear 43 is realized, and further, it is ensured that the rocker assembly 2 can drive the massage head 1 along a predetermined trajectory, thereby completing the shaking head action of the massage head 1 and realizing the stable operation of the head massager. The above structure is simple and reliable, has good transmission effect and small occupied space, and ensures the efficient and stable operation of the gear set 4.

[0052] Specifically, the driving gear 43 rotates in the same direction as the driving gear 41, the double gear 42 rotates in the opposite direction to the driving gear 41, and the driving gear 43 rotates in the opposite direction to the driving gear 41.

[0053] Furthermore, in the plane where any rocker main body 21 swings relative to the housing, there are also the axes of the corresponding driving gear 43, the axes of the corresponding double gears 42, and the axis of the driving gear 41.

[0054] Through the above position limitation, the relative position relationship between the rocker assembly 2 and the corresponding driving gear 43, the corresponding double gears 42, and the driving gear 41 is planned, which ensures the transmission effect, reduces the occupied space, avoids the risk of jamming between the rocker assembly 2 and the gear set 4, and ensures the smooth transmission of the driving unit 6 to the massage head 1.

[0055] Specifically, all the rocker bodies 21 swing synchronously closer to or farther away from the driving gear 41, and the angle between each rocker body 21 and the axis of the driving gear 41 remains unchanged all the time.

[0056] When the driving gear 43 rotates, the groove wall of the special-shaped groove 431 pushes the sliding member 23 to move towards or away from the driving gear 41. Since the rocker body 21 is hinged to the housing cover 3, the rocker body 21 can only move along with the movement of the sliding member 23, causing the massage head 1 to swing away from or towards the axis of the driving gear 41. When the sliding member 23 is pushed by the driving gear 43 to the limit position, at this time, the massage head 1 also swings to the limit position. Specifically, the angle between the two limit positions of the swing of the rocker body 21 is 30°, and the limit positions of the swing of the rocker body 21 can be adjusted according to needs.

[0057] The rotating shaft includes a first rotating shaft 61 and a second rotating shaft 62. The number of the first rotating shafts 61 is the same as that of the double gears 42, and each double gear 42 is rotatably connected to a first rotating shaft 61, and each double gear 42 rotates along the axis of the corresponding first rotating shaft 61; the number of the second rotating shafts 62 is the same as that of the driving gears 43, and each driving gear 43 is rotatably connected to a second rotating shaft 62, and each driving gear 43 rotates along the axis of the corresponding second rotating shaft 62.

[0058] As Figure 1 、 Figure 6 and Figure 11 shown, in another implementation manner of this embodiment, the number of the driving gears 43 is even; the gear set 4 further includes a worm gear 44, two worm shafts 45 and two double gears 42. The output shaft of the driving unit 6 is coaxially fixed to the worm shaft 45, and the driving unit 6 is used to drive the worm shaft 45 to rotate along its own axis. The two worm gears 44 are located on both sides of the worm shaft 45 and mesh with the worm shaft 45. The two double gears 42 are respectively meshed with the two worm gears 44, and each double gear 42 is used to drive half of the driving gears 43.

[0059] By setting the worm gear 44, the two worm shafts 45 and the double gears 42, the transmission purpose of the gear set 4 can be satisfied. The transmission efficiency of the transmission method of the cooperation between the worm gear 44 and the worm shaft 45 is high and the occupied space is small. By setting the double gears 42 and the worm gear 44 between the driving gears 43 and the worm shaft 45, all the driving gears 43 can be distinguished, and then all the driving gears 43 are divided into two groups with different rotation directions. The above limitations help to realize the action differences between different rocker assemblies 2, thus helping to optimize the shaking head action of the massage head 1, facilitating the optimized design of the head massager, and further improving the user experience. The above structure is simple and reliable, has good transmission effect and small occupied space, and ensures the efficient and stable operation of the gear set 4.

[0060] Further, the number of driving gears 43 is four; the two driving gears 43 driven by each double gear 42 are respectively located on both sides of the corresponding double gear 42. The swinging axes of all rocker bodies 21 hinged on the housing are parallel to each other. The rotation directions of the two driving gears 43 driven by the same double gear 42 are opposite, and the rotation directions of the two driving gears 43 driven by different double gears 42 and located on the same straight line are opposite.

[0061] Through the above limitations, the layout positions of each rocker assembly 2 are planned, and the movement tracks of each massage head 1 are adjusted, which helps to further improve the structure of the head massager. Combined with the planning of the rotation directions of the driving gears 43, it helps to adjust the action modes of the massage heads 1 and improve the massage effect of the head massager.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
