Description

A hand massager Technical Field

[0001] This invention relates to massage equipment, and more specifically to a hand massager. Background Technology

[0002] Hand massagers are products designed to massage the human hand. Current hand massagers generally use airbag components. During use, the hand is placed between the airbags, and the expansion and contraction of the airbags provide a swirling, squeezing massage. However, some airbag components in hand massagers have overly simple designs. For example, the upper and / or lower airbags (sheet-like or strip-shaped airbags) simply compress and massage the palm and fingers by inflating and deflating, resulting in a monotonous massage technique and a poor user experience. Some airbag components connect finger airbags to the palm airbag. These finger airbags use four or five annular airbags for the fingers to pass through, covering them and massaging them by inflating and deflating. However, the continuous arrangement of multiple annular airbags to form finger airbags, often in a single integrated structure, leads to increasingly complex finger airbag structures, cumbersome manufacturing processes, and high production costs. Furthermore, finger airbags with multiple interconnected ring-shaped air bladders can only be inflated simultaneously during use, which lacks flexibility (e.g., it's inconvenient to massage injured fingers), and is also difficult to repair or replace when damaged, potentially requiring the replacement of the entire finger airbag. This case arises from this issue. Summary of the Invention

[0003] The purpose of this invention is to provide a hand massager that can massage the hands from all directions, with good massage effect and flexible use. The structure of the finger airbags for massaging the fingers is simpler and the manufacturing cost is lower.

[0004] To achieve the above objectives, the solution of the present invention is:

[0005] A hand massager includes a shell, an inner shell, an air supply massage component, and a control mainboard. Both the shell and the inner shell are open at both ends and hollow inside, forming an accommodating space between them. A massage space is formed inside the inner shell. The air supply massage component includes an air pump, an air valve, and air bags. The control mainboard, air pump, and air valve are disposed within the accommodating space. The air bags are disposed within the massage space. The air bags include an upper air bag, a lower air bag, and finger air bags that are not connected to the upper or lower air bags. The upper air bag is disposed at the top of the inner shell, and the lower air bag is disposed at the bottom of the inner shell. The finger air bags include a cover air bag and five finger air bladders into which fingers can be inserted. The finger air bladders are disposed at the bottom or top of the inner shell and are located in front of the lower or upper air bag, respectively. Each finger air bladder is a strip-shaped air bladder with a U-shaped cross-section and an open end. The cover air bag is disposed opposite to the finger air bladders inside the inner shell and covers the open end of the finger air bladders.

[0006] Furthermore, the finger airbags are formed by bending and shaping strip-shaped airbag sheets. The air cavities formed by each finger airbag are independent and do not communicate with each other. The five finger airbags are arranged in a row, and at least two adjacent finger airbags are connected to form a whole structure.

[0007] Furthermore, each finger airbag has a bottom surface and two side surfaces. The adjacent side surfaces of adjacent finger airbags abut against each other. The outer side surfaces of the two finger airbags at the beginning and end abut against the inner wall of the inner shell. The inner shell also has at least one partition plate protruding between two adjacent finger airbags, and the side surfaces of the finger airbags abut against the partition plate.

[0008] Furthermore, among the five finger airbags, two or three finger airbags located in the middle are connected together to form an airbag connection group. The top of the adjacent sides of the adjacent finger airbags in the airbag connection group are connected, and the sides at both ends of the airbag connection group are respectively provided with partitions.

[0009] Furthermore, each finger airbag has a first air nozzle at its bottom.

[0010] Furthermore, the upper air bag and the lower air bag are connected and folded in the middle, and the upper air bag and the lower air bag are either connected or not connected. The upper air bag and the lower air bag are respectively connected to a second air bag on a first air bag.

[0011] Furthermore, the upper and lower air bags are each equipped with a second air nozzle. The second air bag is T-shaped and is connected to the corresponding first air bag through at least one connecting air nozzle.

[0012] Furthermore, the air bag is rectangular, and a third air nozzle is provided at the bottom of the air bag.

[0013] Furthermore, the outer casing also has a button section, and both the air pump and the button section are electrically connected to the control motherboard.

[0014] Furthermore, the massage space is equipped with a glove that allows the hand to be inserted. The glove is installed inside the inner shell and includes a finger area and a palm area. The upper and lower air bags correspond to the outer side of the palm area of ​​the glove, and the finger air bags correspond to the outer side of the finger area of ​​the glove.

[0015] With the above structure, in the hand massager of the present invention, the finger airbags are not connected to the upper and lower airbags. Five independent, ring-shaped air bladders surround each finger, providing massage. Multiple finger airbags can work independently or synchronously, allowing for flexible massage of different parts of the hand through adjustment, increasing the massage effect and improving ease of use. The structure of the finger airbags in the massager of the present invention is simpler; they are formed by shaping a sheet into a finger airbag and then positioning it. The open surface of the U-shaped finger airbag is filled by covering it with an airbag, satisfying the need for finger encirclement. Furthermore, the overall structure of the finger airbags is simple, resulting in lower manufacturing costs and easy repair and replacement after damage. Attached Figure Description

[0031] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0032] Referring to Figures 1 to 4, this invention discloses a hand massager, including a shell 1, an inner shell 2, an air-supplying massage component A, and a control mainboard 31. Both the shell 1 and the inner shell 2 are open at both ends and hollow inside. The shell 1 is fitted over the outer side of the inner shell 2. After the shell 1 and the inner shell 2 are fitted together, a through space F is formed in the middle. An accommodating space B is formed between the shell 1 and the inner shell 2, and a massage space C is formed inside the inner shell 2. An air bag A1 is disposed in the massage space C. In this embodiment, the shell 1 is assembled from an upper shell 11 and a lower shell 12 (which can be locked together by screws), and the inner shell 2 is assembled from an upper inner shell 21 and a lower inner shell 22 (which can be locked together by screws). The air-supplying massage component A includes an air pump 41, an air valve 42, and an air bag A1. The control mainboard 31, the air pump 41, the air valve 42, and other components are all disposed in the accommodating space B, separated from the air bag A1 in the massage space C to avoid interference. As shown in Figure 3, in this embodiment, the control motherboard 31 is disposed on the bottom surface of the upper shell 11, and the air pump 41 and air valve 42 are fixed on the bottom surface of the lower inner shell 22. Alternatively, the air pump 41 and air valve 42 can be fixed on the top surface of the upper inner shell 21 and located at the bottom of the upper shell 11 (as shown in the embodiment in Figure 5). A rechargeable battery 43 can also be disposed between the outer shell 1 and the inner shell 2. The rechargeable battery 43 is connected to a battery circuit board disposed inside the outer shell 1 (not shown in the figure; the battery circuit board can also be disposed on the inner shell 2). The battery circuit board is electrically connected to the control motherboard 31. The outer shell 1 can also be provided with a charging port electrically connected to the battery circuit board, so that the rechargeable battery 43 can be charged by an external power source.

[0033] In this invention, the air bag A1 includes an upper air bag 5, a lower air bag 6, and a finger air bag 7 that is not connected to either the upper air bag 5 or the lower air bag 6. The upper air bag 5 is located at the top of the inner shell 2, meaning it can be connected to the bottom surface of the upper inner shell 21. The lower air bag 6 is located at the bottom of the inner shell 2, meaning it can be connected to the upper side surface of the lower inner shell 22. The finger air bag 7 includes a cover air bag 71 and five finger air bladders 72 into which fingers can be inserted. The finger air bladders 72 can be located at the bottom or top of the inner shell 2, meaning they can be located on the lower inner shell 22 or the upper inner shell 21. Correspondingly, the finger air bladders 72 are located in front of the lower air bag 6 or the upper air bag 5. Each finger airbag 72 is a U-shaped strip-shaped airbag. Therefore, one end of the finger airbag 72 has an opening b. An opening b is formed on one side of the finger airbag 72 along its length. The cover airbag 71 is positioned inside the inner shell 2 opposite to the finger airbag 72. The cover airbag 71 is positioned on the upper inner shell 21 or the lower inner shell 22 opposite to the finger airbag 72. Correspondingly, the cover airbag 71 is also located in front of the upper airbag 5 or the lower airbag 6. With the above arrangement, the cover airbag 71 is located on the side of the finger airbag 72 with the opening b and covers the opening b of the finger airbag 72, thereby surrounding the finger (not shown in the figure) that is inserted into the finger airbag 72, forming an airbag surrounding ring that can cover the finger.

[0034] As shown in Figures 2 and 4, in this embodiment, the cover airbag 71 is located at the top of the inner shell 2 and in front of the upper airbag 5, and the finger airbag 72 is located at the bottom of the inner shell 2 and in front of the lower airbag 6. The cover airbag 71 covers the finger airbag 72 to surround the finger, thereby forming a wrap-around airbag massage for the fingers inserted into each finger airbag 72.

[0035] The air bag A1 can be made of TPU material, which facilitates production and enhances durability. The air bag forms a chamber for gas expansion and contraction. The finger air bag 7 is not connected to the upper air bag 5 and the lower air bag 6, and can be independently controlled by inflating the finger air bag 7. This allows for selective adjustment to massage different parts of the hand. Each air bag is equipped with an inflation nozzle for easy control of the air valve's inflation. For the attachment of the air bags (upper air bag 5, lower air bag 6, and finger air bag 7) to the inner side of the inner shell 2, the back of the air bag can be glued to the inner wall of the inner shell 2. Simultaneously, the air nozzles on the back of each air bag can also be fixed to the inner shell 2, providing a certain positioning function.

[0036] Specifically, the finger airbags 72 are formed by bending and shaping a strip-shaped airbag sheet d. The U-shaped finger airbags 72 have a certain supporting strength. The air cavities c formed by each finger airbag 72 are independent and do not communicate with each other. The five finger airbags 72 are arranged in a way that allows at least two adjacent finger airbags 72 to be connected into a single structure. As shown in Figure 4, each finger airbag 72 has a bottom surface 721 and two side surfaces 722. The side surfaces 722 of adjacent finger airbags abut against each other. The outer side surfaces of the first and fifth finger airbags 72 located at the beginning and end can abut against the inner wall 20 of the inner shell 2, thus confining the five finger airbags 72 within the inner shell 2. The finger airbags 72 are designed to match the length and width of the fingers, allowing the fingers to be inserted into the cavities formed by the five finger airbags 72.

[0037] To better separate the finger airbags 72 and provide support between them, preventing deformation of the row of finger airbags 72 in the middle, at least one partition plate 23 can be protruding in the inner shell 2, separating adjacent finger airbags 72. The side of the finger airbag 72 abuts against the partition plate 23. As shown in Figure 4, in this embodiment, the partition plate 23 protrudes from the bottom of the inner shell 2 (the upper side of the lower inner shell 22). Among the five finger airbags 72, two or three finger airbags 72 located in the middle can be connected to form an airbag connecting group a. The tops of adjacent side surfaces 722 of adjacent finger airbags 72 in the airbag connecting group a are connected. This can be achieved by dividing a single sheet of material into two or three independent finger airbags 72 and then shaping them into a U-shape, which simplifies production costs and reduces installation work. Furthermore, partition plates 23 are provided on the outer sides of the airbag connecting group a at both ends to limit the airbag connecting group a, prevent deformation, and enhance its support stability. In this embodiment, the three finger-shaped airbags 72 in the middle are connected as a whole to form an airbag connection group a. Both sides of the airbag connection group a are provided with partition plates 23, and each finger-shaped airbag 72 on both sides is also limited between the partition plates 23 and the inner sidewall 20 of the inner shell 2, which simplifies the overall installation structure and ensures the stability of the support during use.

[0038] Each finger airbag 72 has a first air nozzle 44 at its bottom. Each first air nozzle 44 can be connected to an air valve 42 through a first air tube (not shown in the figure). Each finger airbag 72 can be independently controlled to inflate and deflate through a separate air valve. When a finger is injured and not being massaged, the airbag 72 of that finger can be deactivated, improving the flexibility of use. To simplify the structure, at least two first air tubes can be simultaneously connected to a connecting tube head (not shown in the figure) at the end near the finger airbag 72, and then connected to the air valve 42 through a manifold air tube. The connecting tube head has multiple branch connectors and a main connector. The branch connectors connect to each first air tube, and the main connector connects to the manifold air tube. For example, airbag connection group a can be connected through three first air tubes and then connected to a single air tube before being synchronously controlled by the air valve 42.

[0039] The upper air bag 5 and the lower air bag 6 can be independently configured or connected. In this embodiment, the upper air bag 5 and the lower air bag 6 are connected and folded in the middle. The structures of the upper air bag 5 and the lower air bag 6 are roughly the same. The upper air bag 5 includes a second air bag 52 connected to a first air bag 51, and the lower air bag 6 includes a second air bag 62 connected to a first air bag 61. The second air bag 52 is located on the surface of the first air bag 51 facing the hand and corresponding to the middle position of the back of the hand. The second air bag 62 is located on the surface of the first air bag 61 facing the hand and corresponding to the middle position of the palm. The second air bags 52 and 62 can be T-shaped, thereby strengthening the massage of the center of the palm and improving the comfort of the massage.

[0040] The upper air bag 5 and the lower air bag 6 are each equipped with a second air nozzle 45, which is connected to the air valve 42 via a second vent pipe. The upper air bag 5 and the lower air bag 6 can be connected or independently configured without connection. In the second air bags 52 and 62 of the upper air bag 5 and the lower air bag 6, at least one connecting air nozzle 47 can be connected to the corresponding first air bags 51 and 61 (i.e., the first air bag and the second air bag can achieve gas communication at the joint through the connecting air nozzle), so that when inflating or deflating the upper air bag 5 or the lower air bag 6, the respective second air bags 52 and 62 can be inflated or deflated simultaneously.

[0041] In this embodiment, the cover airbag 71 is rectangular, and a third air nozzle 46 is provided at the bottom of the cover airbag 71. The third air nozzle 46 can be connected to the air valve 42 through a third air tube. The cover airbag 71 covers the top of the five finger airbags 72 and can work synchronously when the finger airbags 72 are working, filling the gap of the U-shaped finger airbags 72 above the fingers and satisfying the massage of the entire finger.

[0042] As shown in Figures 1 and 3, a button section 13 may also be provided on the upper surface of the upper shell 11 of the outer shell 1. Both the air pump 41 and the button section 13 are electrically connected to the control main board 31. The control main board 31 controls the air valve 42. The button section 13 is electrically connected to the control main board 31 and controls the main board 31. The button section 13 can be configured as multiple switches corresponding to control the power supply, air pump, and air valve according to different needs. During operation, the air pump 41 provides gas to each air bag to drive the air bag to inflate or contract. The air bag inflates or contracts to massage the hand. The air valve 42 is located between the air pump 41 and the air bag to control the air flow. To enable the control board 31 to better control the inflation and deflation of the airbags, the air valve 42 can be multiple solenoid valves. The solenoid valves are connected to the control board 31 and the air pump 41. The two ends of the solenoid valves are connected to the inflation nozzle and the air pump through the respective air pipes (first, second, and third air pipes, or a combined air pipe). Each airbag is connected to the air pump through a solenoid valve. The independent or synchronous inflation and deflation of different airbags (and finger airbags) can be achieved through the control of the control board 31 and the button section 13.

[0043] As shown in Figure 2, a glove 8 for inserting a hand is also provided within the massage space C, and the glove 8 is installed inside the inner shell 2. The glove 8 is secured by sewing its outer edge to the edge of the air bag. The glove 8 includes a finger section 81 and a palm section 82. The upper air bag 5 and lower air bag 6 are located on the outer side of the palm section 82 of the glove 8, and the finger air bag 72 is located on the outer side of the finger section 81 of the glove 8. When the user's hand needs a hand massage, it is inserted into the glove 8. The glove 8 can cover the hand, preventing direct contact with the air bag and preventing debris from falling into the inner shell 2 and damaging the air bag. Of course, a heating element can also be attached to the side of the palm section 82 of the glove 8 that does not contact the hand; and a vibrating block can be installed in one of the first air bags 51 or 61 of the upper air bag 5 or lower air bag 6. Both the heating element and the vibrating block are electrically connected to the control main board 31 to enrich the massage functions of the hand massager.

[0044] As shown in Figure 5, this is another embodiment of the present invention. The difference between this embodiment and the previous embodiment is that in this embodiment, the cover air bag 71 is disposed at the bottom of the inner shell 2 and in front of the lower air bag 6, and the finger air bag 72 is disposed at the top of the inner shell 2 and in front of the upper air bag 5. The cover air bag 71 covers the finger air bag 72 to surround the finger, thereby forming a wrap-around air bag massage for the fingers inserted into each finger air bag 72.

[0045] When using the hand massager of the present invention, the hand is inserted into the glove 8, and when the fingers 81 of the glove 8 are inserted, each finger is also inserted into the finger airbag 72. The adjustment is made by the button 13, and the control board 31 controls the upper airbag 5, the lower airbag 6 and the finger airbag 71 to inflate and deflate simultaneously or independently, so as to achieve a full-range massage of the hand.

[0046] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
