Modes for Carrying Out the Invention

[0014] In order to make the above objects, features, and advantages of the present invention clearer and easier to understand, the following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings. In the following description, many specific details are described to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other forms different from the embodiments described herein, and those skilled in the art can make similar improvements without departing from the content of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0015] As shown in FIGS. 1-4, in the present invention, a massager with a telescopic massage head is provided, which includes a massage body that fits around the human neck and at least two massage devices 10. The massage devices 10 are provided on the side of the massage body close to the human body. For each massage device 10, there is a case 11, a drive unit 12 provided inside the case 11, a massage head 13 drivingly connected to the drive unit 12 on the ceiling surface of the case 11, a lift stand 14, a lift part 15, and a lift bracket 16 sequentially provided between the case 11 and the massage head 13 from top to bottom. The lift bracket 16 is fixedly connected to the ceiling surface of the case 11. The lift part 15 is provided on the lift bracket 16. The lift stand 14 abuts against the bottom of the massage head 13. A driving shaft is fixedly connected to the bottom of the massage head 13. One end of the driving shaft 131 away from the massage head 13 penetrates through the lift stand 14, the lift part 15, the lift bracket 16, and the top of the case 11 and is connected to the drive unit 12. A reset spring 133 is provided at the connection end of the driving shaft 131 and the drive unit 12. Specifically, the massage head 13 is driven by the drive unit 12. When the drive unit 12 operates, it drives the driving shaft 131 to operate. Due to the operation of this driving shaft 131, the massage head 13 rotates to massage the human neck. The lift stand 14 and the lift part 15 are fixed between the massage head 13 and the case 11 by the driving shaft 131. And since the driving shaft 131 penetrates through the lift stand 14, the lift stand 14 can slide along the driving shaft 131. When the lift part 15 operates, it lifts the lift stand 14. With the force of the lift part 15, the lift stand 14 lifts the massage head 13, making it easier for the massage head 13 to protrude from the massage body to fit people with different neck sizes or to satisfy those who need strong pressure. Among them,The reset spring 133 is for returning the massage head 13 to its original position. When the massage head 13 is lifted by the force of the lift part 15, one end of the driving shaft 131 is fixedly connected to the massage head 13. Therefore, the driving shaft 131 is pulled out and moved by the massage head 13. At this time, the pulling out of the driving shaft 131 compresses the reset spring 133 thereon to generate a restoring force. When the lift part 15 stops, after the massage head 13 loses the force of the lift part 15, the restoring force of the set spring 133 acts on the driving shaft 131, returns the driving shaft 131, and brings the massage head 13 back to its original position, thereby realizing the contraction of the whole massage head 13 and improving the usage experience of the massager in other usage methods.

[0016] Furthermore, in the present embodiment, the drive unit 12 includes an electric motor 121, an inclined gear 122, a driving gear 123, and an output gear 124. The electric motor 121 is provided on one side within the case 11. The inclined gear 122 is provided on one side of the electric motor 121 and is drivingly connected to the output end of the electric motor 121. The driving gear 123 is provided on one side of the inclined gear 122 and is drivingly connected to the inclined gear 122. The output gear 124 is provided on one side of the driving gear 123 and is drivingly connected to the driving gear 123. The driving shaft passes through one end at the top of the case 11 and is inside the driving gear 123. When the output gear 124 rotates, the driving shaft 131 rotates and can slide axially along the shaft of the output gear. Specifically, both the inclined gear 122 and the driving gear 123 are two-stage gears. When the electric motor 121 operates, it drives the inclined gear 122 in meshing drive to rotate, the inclined gear 122 drives the driving gear 123 in meshing drive to rotate, the driving gear 123 drives the output gear 124 in meshing drive to rotate, and the output gear 124 drives the driving shaft inside it to rotate. Thereby, the driving shaft synchronously rotates the massage head 13. Due to the driving cooperation between the inclined gear 122 and the electric motor 121, the spatial requirement of the case 11 is reduced, and further the volume of the case 11 is reduced.

[0017] Furthermore, the case 11 includes an upper cover 111 and a lower cover 112. The upper cover 111 and the lower cover 112 are fixedly connected. The drive unit 12 is within the lower cover 112. The lower cover 112 is provided with a concave-shaped hole 113 for arranging the output gear 124. At the position corresponding to the motor 121 of the lower cover 112, several ventilation holes 114 are provided. Specifically, since the output gear 124 is in a hollow cylindrical shape, in this embodiment, one sunken concave-shaped hole 113 is provided within the lower cover 112 so that the bottom of the output gear 124 can be inserted into the concave-shaped hole 113. The concave-shaped hole 113 restricts the parallel movement of the output gear 124 and at the same time does not restrict the rotation of the output gear 124. The output gear 124 can be rotated by the driving gear 123 and further rotate the driving shaft 131; also, in order to timely release the heat generated during the operation of the motor 121 and avoid the influence of overheating of the motor 121 on its operation, several ventilation holes 114 are provided at the position corresponding to the motor 121 of the lower cover 112.

[0018] Furthermore, in the present embodiment, a fixing block 132 is provided at one end of the driving shaft 131 that penetrates the top of the case 11. The fixing block 132 cooperates with the output gear 124, and the driving shaft 131 rotates together with the output gear 124 and / or slides along the output gear 124 within the output gear 124 by the fixing block 132. One end of the reset spring 133 abuts against the fixing block 132, and the other end abuts against the inner wall of the upper cover 111. Specifically, a fixing block 132 is provided at one end of the driving shaft 131 within the case 11 so that the driving shaft 131 can slide axially along the output gear 124 within the output gear 124 and rotate synchronously with the rotation of the output gear 124 at the same time. This fixing block 132 has other polymorphic forms that are not circular, and the inside of the output gear 124 cooperates with the fixing block 132. The fixing block 132 can slide axially along the output gear 124 within the output gear 124 and rotate synchronously with the rotation of the output gear 124 at the same time, avoiding the situation where the two collide and can only rotate or slide; also, due to the installation of the fixing block 132, when the driving shaft 131 is pulled out, the reset spring 133 is pressed and compressed by the fixing block 132, and when the reset spring 133 exerts a restoring force, by using the fixing block 132 as the force point, the driving shaft 131 is pulled back to its original position.

[0019] Furthermore, in this embodiment, a boot block protruding horizontally is provided on the side wall of the lift bracket 16, and a vertical boot groove is provided on the side wall of the lift stand 14. The boot groove fits the boot block, and the boot block is within the boot groove. Specifically, in order to prevent the lift stand 14 from rotating synchronously when the driving shaft 131 rotates, a stopper block 161 protruding horizontally is provided on the side wall of the lift bracket 16, and a vertical stopper groove 141 is provided on the side wall of the lift stand 14. This stopper groove 141 fits the stopper block 161, and the stopper block 161 is within the stopper groove 141. Since the lift bracket 16 is fixedly connected to the upper cover 111 by screws or the like and cannot rotate, the lift stand 14 does not rotate synchronously with the rotation of the driving shaft 131 due to the coordinated restriction of the stopper groove 141 and the stopper block 161, so that the lift parts 15 are not rubbed against each other.

[0020] Furthermore, in this embodiment, the lift part 15 is an airbag. The airbag is in a ring shape, and an aeration port 151 is provided at its bottom. Specifically, in this embodiment, the lift part 15 is an airbag. This airbag is in a ring shape, that is, a hole is provided in the center, so that the driving shaft 131 passes through the hole without affecting the airbag. An aeration port 151 is provided at the bottom of the airbag. The airbag is connected to an external aeration device through the aeration port 151 for aeration. When the airbag is aerated and inflated, it lifts the lift stand 14. The lift stand 14 lifts the massage head 13. The massage head 13 pulls the driving shaft 131. The driving shaft 131 presses and compresses the reset spring 133 through the fixed block 132. When it is not necessary for the massage head 13 to extend, the airbag can exhaust air through the aeration hole, deflate the airbag, and at the same time the lift stand 14 loses the lifting force of the airbag. After the reset spring 133 loses pressure, the released restoring force acts on the fixed block 132, causing the driving shaft 131 to contract, further causing the massage head 13 to contract, and the massage head 13 compresses the lift stand 14 to contract, realizing the contraction of the entire massage head 13.

[0021] To sum up the above, by installing the lift part 15, the present invention enables the massage head 13 to extend to meet the needs of different people. At the same time, by installing the slidable driving shaft 131 and the reset spring 133, when the massage head 13 extends, the driving shaft 131 also extends, and when the massage head 13 contracts, the driving shaft 131 also contracts, completely contracting the entire massage head 13 without affecting other usage methods of the massager, thereby improving the user experience.

[0022] The present invention is not limited to what is described in the specification and embodiments. Since further advantages and modifications can be easily realized by those skilled in the art, without departing from the spirit and scope of the general concept defined by the claims and the equivalent scope, it is not limited to specific details, representative devices, and the illustrated examples shown and described in this specification.
