Description

Technical Field

[0001] This utility model relates to the field of hand rehabilitation and massage equipment technology, specifically a massager with the function of stretching and bending the hand. Background Technology

[0002] Most hand massagers on the market currently offer limited functionality, primarily relying on vibration, kneading, or air pressure massage. Their functions are relatively simple, and they often focus on the palm or forearm, offering insufficient support for finer finger massage and joint mobility. For users with stiff hands, limited joint mobility, or those requiring rehabilitation training, existing products struggle to provide a comprehensive solution that simultaneously offers stretching, bending, and zoned massage. Furthermore, traditional hand massagers have fixed structures, lacking the flexibility to adapt to different hand shapes and activity levels.

[0003] Therefore, we propose a massager with a function of stretching and bending the hand to solve the problems mentioned above. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides a technical solution: a massager with a function of stretching and bending the hand, comprising: a shell 1, a hole for inserting the palm at one end of the shell 1, a palm inner shell 2 fixedly disposed inside the shell 1, a finger inner shell 3 movably disposed inside the shell 1, the palm inner shell 2 and the finger inner shell 3 being connected by a spring 35, and a first air bag 36 being disposed at the upper part of the joint between the finger inner shell 3 and the palm inner shell 2.

[0027] The inner shell of the finger 3 is symmetrically connected to the two sides of the protruding shaft 33. The inner shell of the finger 3 is also integrally connected to the two sides of the pin 34. One end of the spring 35 is connected to the pin 34, and the other end of the spring 35 is connected to the inner shell of the palm 2.

[0028] The housing 1 is provided with an upper limit plate 11 and a lower limit plate 12. The upper limit plate 11 and the lower limit plate 12 are slidably connected with a convex shaft 33 and a pin 34. The corner of the lower limit plate 12 away from the inner housing 2 of the palm is an arc angle. The convex shaft 33 is slidably set to fit the arc angle.

[0029] When the finger airbag 6 and the palm airbag 21 are inflated first to compress and fix the palm and fingers, the first airbag 36 is inflated, pushing the finger inner shell 3 away from the palm inner shell 2. During this process, the movement direction of the finger inner shell 3 is guided by the limiting sliding cooperation of the pin 34, the convex shaft 33 and the upper limit plate 11 and the lower limit plate 12, so that the finger inner shell 3 moves away from the palm inner shell 2 in a straight line, stretching the joint of the finger and the palm. The spring 35 is stretched. When the convex shaft 33 enters the arc angle area, it is pulled by the spring 35. At the same time, the finger inner shell 3 is pushed by the first airbag 36, so that the finger inner shell 3 rotates downward about the pin 34 as the axis. With the palm facing upward, the fingers are pulled away from the palm.

[0030] The right end of the inner shell 3 of the finger is integrally connected to the first baffle 32. The first baffle 32 is fixedly connected to the side of the first air bag 36. The inner shell 2 of the palm is provided with a second baffle at the corresponding position. The second baffle and the first baffle 32 clamp the first air bag 36. When the first air bag 36 is inflated, it pushes the first baffle 32 to move relative to the second baffle.

[0031] The housing 1 contains an air pump 4, a battery 7, a circuit board 8, a solenoid valve 9, and an air tube assembly 5. The battery 7 is electrically connected to the circuit board 8, and the circuit board 8 is electrically connected to the solenoid valve 9 and the air pump 4. The solenoid valve 9 is connected to the first air bag 36 and the air pump 4 through the air tube assembly 5. The circuit board 8 controls the operation of the solenoid valve 9 and the air pump 4, and inflates the first air bag 36 through the air tube assembly 5.

[0032] The inner shell 3 of the finger is also provided with a finger air bag 6, which is connected to the air tube assembly 5. The inner shell 3 of the finger has a first through hole 31 through which the air tube assembly 5 passes. When the finger is inserted into the finger air bag 6, the finger is squeezed and massaged by inflating the finger air bag 6.

[0033] Two palm air bags 21 are fixedly installed inside the inner shell 2 of the palm. A heating element is set on the opposite side of the palm air bags 21. The heating element is electrically connected to the circuit board 8. The palm air bags 21 are connected to the air tube assembly 5. By inflating the palm air bags 21, the palm is squeezed and massaged. At the same time, the heating element heats the palm and the back of the hand.

[0034] Working principle: Palm massage function:

[0035] The air pump 4 inflates the palm air bag 21 through the air tube assembly 5, causing it to expand and apply uniform pressure to the palm and back of the hand to achieve squeezing massage.

[0036] At the same time, the heating pad inside the palm air bag 21 generates heat when powered on, providing thermal therapy to the hand and promoting blood circulation.

[0037] Hand flexion and extension assistive function:

[0038] With the palm air bag 21 inflated to fix the palm and the finger air bag 6 inflated to fix the fingers, the circuit board 8 controls the air pump 4 to start, and inflates the first air bag 36 through the solenoid valve 9 and the air pipe assembly 5, the first air bag 36 gradually expands.

[0039] The expanding first air bag 36 pushes the inner shell of the finger to move the finger in a straight line first, assisting in stretching. Then, it rotates downward around the pin 34 as the axis. When the palm is facing upward, it pulls the finger to extend away from the palm at the finger joint, while stretching the spring 35 to store energy.

[0040] When the solenoid valve 9 switches to exhaust, the first air bag 36 contracts, the spring 35 releases energy, and pulls the inner shell 3 of the finger to reset.

[0041] Repeating the above process can create rhythmic hand flexion and extension movements, which are suitable for hand rehabilitation training and relaxation.

[0042] Finger massage function:

[0043] The finger air bag 6 is also connected to the air pump 4. After inflation, it provides a wrap-around squeezing massage to various parts of the finger.

[0044] This process can be controlled independently or simultaneously with palm massage to achieve precise massage of different areas of the entire hand.

[0045] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
