Abstract
Description
Technical Field
[0001] This utility model relates to the field of massage equipment technology, and in particular to a stretchable hand massager. Background Technology
[0002] In the current technology, most hand massagers on the market only have a pressing and tightening mode to achieve massage and relaxation. Some hand massagers have a more complex structure for hand stretching, which is not suitable for home use.
[0003] Chinese Patent No. CN206081034U discloses a hand massage device, comprising: a lower housing; a stretching body slidably disposed on the lower housing, the stretching body having a clamp for clamping fingers; a fixed shaft disposed on the side wall of the stretching body, the clamp being a simulated massage finger slidably disposed on the fixed shaft; the stretching body reciprocating along a guide rail disposed on the lower housing; a main body wheel rotatably disposed on the fixed shaft, three simulated massage fingers being installed in a groove opened on the main body wheel; the simulated massage fingers are plate-shaped, separating the four fingers of the palm; clamping airbags are disposed on two opposite sides of the stretching body, the two clamping airbags moving relative to each other to clamp the simulated massage fingers.
[0004] While the hand massager in the aforementioned patent fulfills the function of stretching fingers, it has a complex structure, numerous parts, occupies a large space, and uses a clamp for stretching, resulting in low comfort and a poor user experience. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a hand massager that can combine pressing and stretching functions. This solves the problem that traditional hand massagers can only perform single squeezing massage and cannot stretch and relax the ligaments of the hand joints. At the same time, it simplifies the transmission path, has a simple part structure, small size, and is applicable to a wide range of scenarios.
[0006] This utility model provides a stretchable hand massager, which adopts the following technical solution: A stretchable hand massager includes a massager body and a finger stretching mechanism. The massager body includes an inner shell, and the finger stretching mechanism is located at the front end of the massager body and disposed within the inner shell. The finger stretching mechanism includes a finger airbag clamping bag, a telescopic base, and a drive assembly. The finger airbag clamping bag is fixedly installed on the telescopic seat, and the telescopic seat is slidably installed on the inner liner shell; the drive assembly includes a telescopic airbag and an elastic sheet, and the telescopic airbag is connected to an air pump installed on the inner liner shell; The inner liner shell is fixedly provided with a first limiting base, and the telescopic airbag acts between the first limiting base and the telescopic base; the elastic sheet acts between the inner liner shell and the telescopic base, and the arched part of the elastic sheet abuts against the telescopic base; When the telescopic airbag inflates, it pushes the telescopic seat to extend the finger airbag gripper bag forward, while simultaneously squeezing the elastic plate to cause it to deform elastically. When the telescopic airbag deflates and contracts, the elastic plate releases elastically and rebounds, pulling the telescopic seat and the finger airbag gripper bag backward to achieve a reset.
[0007] By adopting the above technical solution, a telescopic seat driven by a telescopic airbag and an elastic plate is set in the massager body, and a finger airbag clamping bag is equipped at the front end of the telescopic seat. The air pump inflates and deflates the telescopic airbag, and at the same time, the elastic plate returns to its original position, which drives the telescopic seat to slide back and forth, causing the finger airbag clamping bag to complete the pulling and relaxing action of the fingers. On the basis of pressing the hands and fingers, the finger stretches simultaneously, effectively loosening the finger joints, stretching the ligaments, and improving the problems of hand stiffness and tendon sheath tightness. The overall structure is integrated inside the inner shell, with a compact and simple layout. It relies on pneumatic means to drive the pressing and stretching actions simultaneously, which is simple to control and runs smoothly. By operating the airbag massage and finger stretching modes in tandem, a more comprehensive massage and physiotherapy effect can be achieved, and the product is applicable to a wider range of scenarios and suitable users.
[0008] The present invention is further configured such that: the inner lining shell is integrally formed or fixedly assembled from an inner lining upper cover and an inner lining lower cover; the telescopic seat includes a front slide, a first upright plate, a connecting arm disposed in the middle of the first upright plate, and a second upright plate; both sides of the front slide are provided with sliding protrusions, the inner lining lower cover is provided with a slot adapted to the front slide, and both sides of the slot are provided with guide grooves for the sliding protrusions to slide; the inner lining lower cover is provided with two second limiting bases for limiting the first upright plate.
[0009] By adopting the above technical solution, the inner liner shell is divided into an upper inner liner cover and a lower inner liner cover. This allows for both integrated molding to simplify the processing steps and improve the overall structural strength, and a modular assembly mode to facilitate the disassembly, inspection, and subsequent replacement and maintenance of the internal air pump and various airbag components. The connecting arm is located in the middle of the first upright plate, which allows the driving force of the telescopic airbag and elastic sheet to be evenly and centrally transmitted to the entire telescopic seat, avoiding unilateral jamming or sliding deviation caused by force skew, and improving the finger gripping experience. The sliding protrusions on both sides of the front slide slide back and forth in the guide groove, ensuring smooth sliding and preventing deviation or jamming during operation, thus ensuring stable and reliable telescopic movement. The lower inner liner cover is equipped with a second limiting base, which forms a limiting constraint on the first upright plate of the telescopic seat, effectively limiting the telescopic seat from overtravel and improving the overall operational stability of the mechanism. The present invention is further configured such that: the elastic sheet is an integral open elastic sheet with two elastic arms, the connecting arm passes between the two elastic arms, the two ends of the elastic sheet are respectively fixedly connected to the second limiting base, and the center distance between the two second limiting bases is less than the total length of the elastic sheet, the arched parts of the two elastic arms are provided with limiting bosses facing each other, the connecting arm and the second upright plate are provided with a first notch, and the limiting bosses are inserted into the first notch to form a snap-fit limiting fit.
[0010] By adopting the above technical solution, the elastic sheet adopts an integrated open spring sheet structure with two elastic arms. It has fewer parts, simple molding, and convenient assembly. The two ends of the elastic sheet are respectively attached to two second limiting bases, and the center distance between the two bases is less than the total length of the elastic sheet. After assembly, the elastic sheet is naturally pre-tightened and stores energy, continuously forming an elastic reset force on the telescopic seat. The two elastic arms have limiting bosses facing each other at their arched parts. The connecting arm passes between the two elastic arms. The limiting bosses are engaged with the first notch at the connection between the connecting arm and the second vertical plate to form a snap-locking limit. With the elasticity of the elastic sheet itself, the automatic rebound reset action is realized. Combined with the sliding guide structure, the overall action reliability is improved. The structure is simplified, the assembly is compact, no additional parts are required, and the reset and locking function is stable and durable.
[0011] The present invention is further configured such that: a second notch is provided on the first limiting base; an air nozzle is fitted at one end of the telescopic airbag, the air nozzle is engaged with the second notch, and the other end of the telescopic airbag acts on the second upright plate; an upper airbag and a lower airbag are respectively provided on the upper inner cover and the lower inner cover, and the lower airbag, the telescopic airbag and the finger airbag clamping bag are all connected to the air pump through an air valve; and thumb holes for thumbs to pass through are provided on both sides of the lower airbag.
[0012] By adopting the above technical solution, the air nozzle of the telescopic airbag is snapped into the second notch of the first limiting base, ensuring a firm and stable positioning without the need for additional fasteners, reducing redundant parts, resulting in a compact overall structure and higher assembly positioning accuracy. The upper and lower inner liner covers are respectively equipped with upper and lower airbags, which can simultaneously cover and massage the front and back of the palm, increasing the overall massage coverage of the palm. The lower airbag has a thumb hole to accommodate the thumb alone, adapting to the natural hand position. At the same time, the thumb can be simultaneously pressed and squeezed by the airbag in the hole, achieving targeted stretching massage. Each airbag is connected to the air pump through an air valve, which can complete the inflation and deflation actions simultaneously or in sections to meet different needs.
[0013] The present invention is further configured such that: the massager body is also provided with a lithium battery for powering the air pump, and the end of the massager body is provided with a charging interface for connecting an external power source.
[0014] By adopting the above technical solution, the lithium battery can independently power the air pump, making it flexible and portable in various usage scenarios without restrictions; when paired with an external power source to charge the lithium battery, it can be repeatedly charged and discharged, saving energy and being environmentally friendly.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0026] The following will refer to the appendix in the embodiments of this utility model. Figure 1-9 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] As attached Figure 1-9 As shown, a stretchable hand massager includes a massager body and a finger stretching mechanism. The massager body includes an outer shell 13 and an inner shell 5. The outer shell 13 is integrally formed or fixedly assembled from an upper outer shell cover 131 and a lower outer shell cover 132. The inner shell 5 is integrally formed or fixedly assembled from an upper inner shell cover 51 and a lower inner shell cover 52. The finger stretching mechanism is located at the front end of the massager body and is disposed in the inner shell 5. The finger stretching mechanism includes a finger airbag clamping bag 1, a telescopic base 2, and a drive assembly. The finger airbag holding bag 1 is an airbag bag with four semi-cylindrical independent air chambers arranged side by side, which is fixedly installed on the telescopic seat 2. The telescopic seat 2 is slidably installed in the inner liner shell 5. The driving component includes a telescopic airbag bag 3 and an elastic sheet 4. The telescopic airbag bag 3 is connected to an air pump 6 installed on the inner liner shell 5. The inner liner shell 5 is fixedly provided with a first limiting base 14, and the telescopic airbag 3 acts between the first limiting base 14 and the telescopic seat 2; the elastic sheet 4 acts between the inner liner shell 5 and the telescopic seat 2, and the arched part 42 of the elastic sheet 4 abuts against the telescopic seat 2.
[0028] Specifically, as shown in the attached document Figure 2-6As shown, the telescopic seat 2 consists of a front slide 211, a first upright plate 212, a connecting arm 213, and a second upright plate 214. The connecting arm 213 is located in the middle of the first upright plate 212, so that the driving force of the telescopic airbag 3 and the elastic sheet 4 is evenly and centrally transmitted to the entire telescopic seat 2, avoiding unilateral jamming or sliding deviation caused by force skew, and improving the finger gripping experience. The front slide 211 has sliding protrusions 215 on both sides. The inner liner cover 52 has slots 10 that are adapted to the front slide 211. Limiting strips 11 are provided on both sides of the slots 10. The slots 10 and the corresponding limiting strips 11 on both sides form a guide groove 12 for the sliding protrusions 215 to slide back and forth, ensuring that the telescopic action is smooth and reliable. The inner liner cover 52 is provided with two second limiting bases 15 for limiting the first upright plate 212.
[0029] Furthermore, as shown in the appendix Figure 3 and 7 As shown, the elastic sheet 4 is an integral open elastic sheet with two elastic arms 41. Both ends of the elastic sheet 4 are fixedly connected to the second limiting base 15, and the center distance between the two second limiting bases 15 is less than the total length of the elastic sheet 4. After assembly, the elastic sheet 4 naturally pre-tightens and stores energy, continuously generating an elastic restoring force on the telescopic seat 2. The connecting arm 213 passes between the two elastic arms 41. The arched portions 42 of the two elastic arms 41 have opposing limiting bosses 43. A first notch 16 is provided at the connection between the connecting arm 213 and the second upright plate 214. The limiting boss 43 engages with the first notch 16 to form a snap-fit limiting fit. This structure relies on the elasticity of the elastic sheet 4 itself to achieve automatic springback and reset, eliminating the need for additional elastic parts. The reset and locking functions are stable and durable. Simultaneously, the two elastic arms 41 can provide lateral restraint to the connecting arm, preventing the telescopic seat 2 from moving up and down or swaying during operation, and also concentrating the elastic force in the center, resulting in a more uniform force distribution.
[0030] Furthermore, as shown in the appendix Figure 4-5 As shown, a second notch 17 is provided on the first limiting base 14; one end of the telescopic airbag 3 is equipped with an air nozzle 18, which is snapped into the second notch 17, and the other end of the telescopic airbag 3 acts on the second upright plate 214, so that the positioning is firm and stable and no additional fasteners are required.
[0031] In this utility model, as shown in the appendix Figure 2 and 8 As shown, the upper inner cover 51 and the lower inner cover 52 are respectively provided with an upper airbag 8 and a lower airbag 9. The lower airbag 9, the telescopic airbag 3 and the finger airbag clamping bag 1 are all connected to the air pump 6 through the air valve 7. The lower airbag 9 has thumb through holes 91 on both sides for the thumb to pass through and place.
[0032] The user inserts four fingers into the finger airbag holding bag 1 and the thumb into the thumb through hole 91. When the air pump works, it inflates the finger airbag holding bag 1, the upper airbag bag 8, and the lower airbag bag 9, providing both compression and massage to the fingers and palm, and clamping and positioning the fingers and palm. Simultaneously, the telescopic airbag bag 3 inflates and pushes against the second upright plate 214, causing the telescopic seat 2 to slide forward along the guide groove 12 via the sliding protrusion 215, thereby driving the finger airbag holding bag 1 to extend forward, achieving a stretching action on the fingers. During this process, the airbag bag 1 extends forward, providing a stretching action to the fingers. The elastic plate 4 is compressed by the second upright plate 214 and undergoes elastic deformation. When the air pump 6 stops running, the upper airbag 8, lower airbag 9, finger airbag holding bag 1 and telescopic airbag 3 are depressurized through the air valve 7 to relieve pressure on the fingers and palms. At the same time, the telescopic airbag 3 contracts synchronously, causing the elastic plate 4 to release its elastic force and rebound under its own elasticity, pushing the second upright plate 214. Then, the telescopic seat 2 is driven to slide backward along the guide groove 12 through the sliding protrusion 215 to complete the reset of the finger airbag holding bag 1 in preparation for the next round of finger stretching operation.
[0033] In this utility model, as shown in the appendix Figure 1-9 As shown, the massager body is also equipped with a lithium battery 19, which is electrically connected to the air pump 6 through a PCB circuit board to supply power to the air pump 6. The end of the massager body is provided with a charging interface 20 for external power supply. The charging interface 20 is electrically connected to the lithium battery 19 through the PCB circuit board to charge the lithium battery 19, so that the device can be used repeatedly. The massager body can also be equipped with a speaker 21 to output voice reminders to avoid excessive massage caused by prolonged use by the user.
