Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a massage device with an adjustable massage head height. Background Technology

[0002] A massager is a health care device designed based on the principles of physics, bionics, and traditional Chinese medicine. It uses electromagnetic vibration or mechanical rotation to simulate manual massage techniques such as kneading and percussion, helping to relieve muscle fatigue and promote blood circulation. Currently, there are many massage devices on the market, such as massage chairs and massage cushions. To ensure the massage effect, the rotating massage heads of massagers are often designed to protrude quite a bit. This can cause discomfort and discomfort when the user leans back on the massager when not using it, thus reducing the user experience.

[0003] To address the aforementioned issues, existing technologies utilize a single servo drive motor to simultaneously oscillate two dual-head massagers, allowing for overall height adjustment. During massage, the motor raises the two massagers; when not massaging, it lowers them to retract, preventing discomfort from the massagers. However, while this type of structure can simultaneously move both massagers with a single motor, its vertical drive means that once the two massagers reach the contact massage position, they need to continue rotating. However, the rotational force is less than the contact force, resulting in idle rotation. This idle rotation can occur in two ways: one massager works while the other remains inactive, or both massagers remain inactive, thus affecting the massage effect. Utility Model Content

[0004] The purpose of this invention is to provide a massage device with an adjustable massage head height. When the massage head is raised, it avoids spinning idly, allowing it to rotate continuously and thus ensuring a sustained massage effect. When not massaging, the massage head is lowered and retracted, preventing discomfort and improving massage comfort.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: This utility model provides a massage device with an adjustable massage head height, including a housing; The lifting mechanism includes: An electric motor, which is disposed within the housing; A transmission assembly is connected to the output end of a motor, and the motor drives the transmission assembly in conjunction. A threaded screw, which is connected to the output end of a transmission assembly, and the transmission assembly drives the threaded screw to rise, fall, and rotate when they are in tandem. A massage head, which is connected to the top of a threaded screw and rotates with the threaded screw; An anti-spinning mechanism is provided inside the housing and connected to the bottom end of the threaded screw. The anti-spinning mechanism moves up and down with the threaded screw and cooperates with the housing to prevent the threaded screw from spinning idly.

[0006] Furthermore, the anti-idling mechanism includes a connecting rod connected to the bottom end of the threaded screw. The connecting rod is provided with a top stop assembly. The top stop assembly includes a receiving cavity opened on the connecting rod. The receiving cavity is provided with a screw support, a brake pad, and a spring. The screw support is connected to the bottom end of the connecting rod. The brake pad is fitted on the outside of the screw support. The spring is connected between the brake pad and the inner wall of the receiving cavity.

[0007] Furthermore, a lower through hole is provided on the connecting rod above the lead screw bracket. This lower through hole facilitates the insertion of the threaded lead screw into the receiving cavity and its connection with the lead screw bracket. A connecting post is provided in the middle of the receiving cavity, and a connecting hole is provided in the middle of the brake pad to cooperate with the connecting post. One end of the brake pad is tightly attached to the outer wall of the lead screw bracket, and support posts are provided on the other end of the brake pad and the inner wall of the receiving cavity away from the lead screw bracket. The spring is sleeved between the two support posts to press the brake pad against the lead screw bracket.

[0008] Furthermore, washers are provided between the threaded screw and the connecting rod, and between the connecting rod and the screw support. The screw support and the threaded screw, and between the connecting post and the brake pad, are all connected by screws.

[0009] Furthermore, the housing includes a bottom shell, a front shell, and a bottom cover. The front shell has an upper through hole for the threaded screw to pass through. A motor mounting cavity is formed between the bottom shell and the front shell. A lifting cavity is formed between the bottom shell and the bottom cover. The anti-drying mechanism is located in the lifting cavity.

[0010] Furthermore, the lifting cavity is provided with a lifting sleeve post, and the middle part of the connecting rod is provided with a lifting sleeve hole that is sleeved on the outside of the lifting sleeve post.

[0011] Furthermore, the housing is provided with two sets of lifting mechanisms, and the connecting rod is provided with two sets of top stop assemblies connected to the lower part of the corresponding lifting mechanisms. The two sets of top stop assemblies are respectively connected to the two sets of lifting mechanisms. Each set of lifting mechanisms includes a motor, a transmission assembly and a threaded screw.

[0012] Furthermore, the motor is a dual-head motor, and the transmission assembly includes a worm, a transmission gear, and an output gear. The worm is connected to the output shafts at both ends of the motor. The transmission gear includes a lower helical gear and an upper spur gear. The helical gear meshes with the worm, and the spur gear meshes with the output gear. The output gear has an internal thread that connects with a lead screw.

[0013] This invention has the following beneficial effects: In the massage device with an adjustable massage head height, the forward rotation of the motor drives the transmission assembly to move the threaded screw, anti-free rotation mechanism, and massage head up and down together. During the upward massage, the anti-free rotation mechanism prevents the threaded screw and massage head from spinning freely, ensuring continuous rotation of the massage head and maintaining the massage effect. When not massaging, the reverse rotation of the motor drives the transmission assembly to move the threaded screw, anti-free rotation mechanism, and massage head down together, retracting the massage head to avoid discomfort and improve massage comfort.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] This embodiment discloses a massage device with an adjustable massage head height, referring to... Figures 1-5The device includes a housing 1 and a lifting mechanism 2. The lifting mechanism 2 includes a motor 21, which is located inside the housing 1. A transmission assembly is connected to the output end of the motor 21, and the motor 21 drives the transmission assembly in linkage. A threaded screw 22 is connected to the output end of the transmission assembly, and the transmission assembly drives the threaded screw 22 to rise, fall, and rotate when linkage occurs. A massage head 3 is connected to the top end of the threaded screw 22, and the massage head 3 rotates with the threaded screw 22. An anti-spinning mechanism 4 is located inside the housing 1 and connected to the bottom end of the threaded screw 22. The anti-spinning mechanism 4 rises and falls with the threaded screw 22 and cooperates with the housing 1 to prevent the threaded screw 22 from spinning. 2. During idling, the motor 21 drives the transmission assembly in the forward direction, causing the threaded screw 22, anti-idling mechanism 4, and massage head 3 to rise and fall together. During the upward massage, once the threaded screw 22, anti-idling mechanism 4, and massage head 3 have risen to the top of the housing 1, they cannot continue to rise. At this time, the anti-idling mechanism 4 prevents the threaded screw 22 and massage head 3 from spinning idly, allowing the massage head 3 to rotate continuously, thus ensuring a continuous massage effect. When not massaging, the motor 21 drives the transmission assembly in the reverse direction, causing the threaded screw 22, anti-idling mechanism 4, and massage head 3 to descend together, retracting the massage head 3 to avoid discomfort and improve massage comfort.

[0022] Reference Figure 2 , Figure 3 , Figure 5 The anti-spinning mechanism 4 includes a connecting rod 41 connected to the bottom end of the threaded screw 22. The connecting rod 41 is provided with a top stop assembly. The top stop assembly includes a receiving cavity opened on the connecting rod 41. The receiving cavity is provided with a screw support 42, a brake pad 43, and a spring 44. The screw support 42 is connected to the bottom end of the connecting rod 41. The brake pad 43 is fitted on the outside of the screw support 42. The spring 44 is connected between the brake pad 43 and the inner wall of the receiving cavity. The elastic force of the spring 44 pushes the brake pad 43 to constantly press against the screw support 42, so that when the threaded screw 22, the anti-spinning mechanism 4, and the massage head 3 rise together to the top of the housing 1 and can no longer rise, the threaded screw 22 and the massage head 3 can still rotate and massage.

[0023] Reference Figure 2 , Figure 3 , Figure 5The connecting rod 41 has a lower through hole above the lead screw support 42, which facilitates the insertion of the threaded lead screw 22 into the receiving cavity and its connection with the lead screw support 42. A connecting post 45 is provided in the middle of the receiving cavity, and a connecting hole 431 is provided in the middle of the brake pad 43 to cooperate with the connecting post 45. One end of the brake pad 43 is tightly attached to the outer wall of the lead screw support 42, and the other end of the brake pad 43 and the inner wall of the receiving cavity away from the lead screw support 42 are both provided with support posts 432. The spring 44 is sleeved between the two support posts 432. The connecting hole 431 is an elongated hole, which allows the brake pad 43 to move laterally under the action of the spring 44 after it is connected to the connecting post 45, so that the brake pad 43 is always pressed against the lead screw support 42. This facilitates the lifting and lowering of the threaded lead screw 22 and the massage head 3, while also preventing the threaded lead screw 22 and the massage head 3 from spinning freely.

[0024] Reference Figures 2-5 Washers 46 are provided between the threaded screw 22 and the connecting rod 41, and between the connecting rod 41 and the screw support 42. The screw support 42 and the threaded screw 22, and the connecting column 45 and the brake pad 43 are all connected by screws. The washers 46 protect the threaded screw 22, the screw support 42 and the connecting rod 41, and prevent wear between the threaded screw 22, the screw support 42 and the connecting rod 41 during lifting.

[0025] Reference Figure 2 , Figure 3 , Figure 5 The housing 1 includes a bottom shell 11, a front shell 12, and a bottom cover 13. The front shell 12 has an upper through hole for the threaded screw 22 to pass through. A motor mounting cavity 14 is formed between the bottom shell 11 and the front shell 12. A lifting cavity 15 is formed between the bottom shell 11 and the bottom cover 13. The anti-drying mechanism is located in the lifting cavity 15. A lifting sleeve post 151 is provided in the lifting cavity 15. A lifting sleeve hole 411 is opened in the middle of the connecting rod 41, which is sleeved on the lifting sleeve post 151. The threaded screw... 22 moves up and down at both ends of the lifting cavity 15. The connecting rod 41 moves up and down together with the threaded screw 22 in the middle of the lifting cavity 15 through the lifting sleeve hole 411 along the lifting sleeve post 151. During the upward massage, the connecting rod 41 is restricted from continuing to rise by the top of the lifting cavity 15. Then, with the spring 44 elastically supporting the brake pad 43, the brake pad 43 keeps the screw support 42 in place. So even when it cannot continue to rotate and rise, the threaded screw 22 and the massage head 3 can still continue to rotate and massage continuously.

[0026] Reference Figure 2 , Figure 3 , Figure 5The housing 1 contains two sets of lifting mechanisms 2. The connecting rod 41 has two sets of top stop assemblies connected to the lower part of the corresponding lifting mechanisms 2. The two sets of top stop assemblies are respectively connected to the two sets of lifting mechanisms 2. Each set of lifting mechanisms 2 includes a motor 21, a transmission assembly, and a threaded screw 22. The motor 21 is a double-headed motor 21. The transmission assembly includes a worm gear 23, a transmission gear 24, and an output gear 25. The worm gear 23 is connected to the output shafts at both ends of the motor 21. The transmission gear 24 includes a lower helical gear 241 and an upper spur gear 24. 2. The helical gear 241 meshes with the worm gear 23, and the spur gear 242 meshes with the output gear 25. The output gear 25 has an internal thread that connects with the threaded screw 22. During massage, the dual-head motor 21 simultaneously drives the worm gears 23 at both ends to rotate, causing the transmission gear 24 to rotate under the cooperation of the helical gear 241 and the worm gear 23. As the transmission gear 24 rotates, it rotates through the cooperation of the spur gear 242 and the output gear 25. The rotation of the output gear 25 drives the threaded screw 22 to rise and fall, thereby causing the massage head 3 to rotate and achieve massage.

[0027] The working principle of this utility model is as follows: When the product is in use, pressing the power button turns on the motor 21. The worm gears 23 at both ends of the motor 21 drive the two sets of transmission gears 24 and output gears 25 to rotate respectively. The thread on the inner surface of the output gear 25 rotates with the threaded screw 22, and the screw support 42 fixed to the bottom of the threaded screw 22 rotates along with it. The spring 44 on the connecting rod 41 constantly presses against the brake pad 43, so that the brake pad 43 constantly presses against the screw support 42. The force of the brake pad 43 is greater than the force of the threaded screw 22 spinning freely, so that the threaded screw 22 does not spin freely and can spiral upward. When the threaded screw 22 rises to the set height, the connecting rod 41 will be stopped by the bottom. The lifting chamber 15 of the shell 11 blocks its upward movement, preventing it from continuing to rise. At this time, the rotational force is greater than the force resisted by the brake pad 43, and the threaded screw 22 and the massage head 3 fixed on it continue to rotate 360° continuously to achieve massage. When not massaging, the worm gears 23 at both ends drive the two sets of transmission gears 24 and output gears 25 to rotate respectively. The threads on the inner surface of the output gear 25 and the threaded screw 22 rotate, and the screw support 42 fixed at the bottom of the threaded screw 22 rotates together, causing the threaded screw 22 and the massage head 3 to spiral down, retracting the massage head 3. In the retracted state, the pressure of the massage head 3 on the user is eliminated, improving the user's comfort.

[0028] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
