Description

Technical Field

[0001] This utility model 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 hand massagers have overly simple airbag designs, such as upper and / or lower airbags (sheet-like or strip-shaped), resulting in a monotonous massage technique and a poor user experience. Some airbag components connect to finger airbags on the palm airbag. These finger airbags use four or five ring-shaped airbags for the fingers to pass through, covering them and massaging them through inflation and deflation. However, the continuous arrangement of multiple ring-shaped airbags to form a single, integrated structure makes the finger airbag structure increasingly complex, leading to 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. Utility Model Content

[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 this utility model is:

[0005] A hand massager includes a shell, an inner shell, an air-supplying massage component, and a control board. 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-supplying massage component includes an air pump, an air valve, and air bags. The control board, 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 opening at one end. The cover air bag is disposed opposite to the finger air bladders inside the inner shell, and the cover air bag covers the opening of the finger air bladder to surround the finger.

[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, the two or three finger airbags located in the middle are connected 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, and each first air nozzle is connected to an air valve through a first air tube.

[0010] Furthermore, at least two first ventilation tubes are simultaneously connected to a connecting tube head in the end near the finger airbag, and then connected to the air valve through a manifold ventilation tube.

[0011] Furthermore, the upper air bag and the lower air bag are connected and folded in the middle. The upper air bag and the lower air bag each include a second air bag connected to a first air bag. The second air bag is located in the first air bag on the surface facing the hand and corresponds to the middle position of the palm or back of the hand.

[0012] Furthermore, the upper air bag and the lower air bag are each provided with a second air nozzle, and the second air nozzle is connected to the air valve through a second air pipe. The upper air bag and the lower air bag are either connected or not connected. The second air bag is T-shaped and is connected to the corresponding first air bag through at least one connecting air nozzle.

[0013] Furthermore, the air bag is rectangular, and a third air nozzle is provided at the bottom of the air bag. The third air nozzle is connected to the air valve through a third air pipe.

[0014] Furthermore, the outer shell is also equipped with a button section, and both the air pump and the button section are electrically connected to the control motherboard; the massage space is also equipped with a glove that can be inserted into the hand. The glove is installed inside the inner shell and includes a finger section and a palm section. The upper air bag and lower air bag are located on the outer side of the palm section of the glove, and the finger air bag is located on the outer side of the finger section of the glove.

[0015] With the above structure, in this hand massager, 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 simultaneously, allowing for flexible massage of different parts of the hand through adjustment, enhancing the massage effect and improving ease of use. The structure of the finger airbags in this massager is simpler; they are formed by shaping a sheet into a finger airbag and then positioning it. The opening of the U-shaped finger airbag is filled by covering it, ensuring complete finger coverage. The overall structure of the finger airbags is simple, resulting in lower manufacturing costs and easy repair and replacement after damage. Attached Figure Description

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] Combination Figures 1 to 4 As shown, this utility model discloses a hand massager, including a shell 1, an inner shell 2, an air supply massage component, 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, and after the shell 1 and the inner shell 2 are fitted together, a through space is formed in the middle. An accommodating space is formed between the shell 1 and the inner shell 2, and a massage space is formed inside the inner shell 2, where an air bag is placed. In this embodiment, the shell 1 is assembled from an upper shell 11 and a lower shell 12 (which can be locked together with 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 with screws). The air supply massage component includes an air pump 41, an air valve 42, and an air bag. The control mainboard 31, the air pump 41, the air valve 42, and other components are all placed in the accommodating space, separated from the air bag in the massage space to avoid interference. 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. 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.

[0030] In this invention, the airbag includes an upper airbag 5, a lower airbag 6, and a finger airbag 7 that is not connected to either the upper or lower airbag 6. The upper airbag 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 airbag 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 airbag 7 includes a cover airbag 71 and five finger airbags 72 into which fingers can be inserted. The finger airbags 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 airbags 72 are located in front of the lower airbag 6 or the upper airbag 5. Each finger airbag 72 is a U-shaped strip-shaped airbag. Therefore, one end of the finger airbag 72 has an opening, allowing the cover airbag 71 to be 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 lower inner shell 22 opposite to the finger airbag, and correspondingly, it is located in front of the upper airbag 5 or lower airbag 6. Through this arrangement, the cover airbag 71 is located on the side of the finger airbag 72 with an opening and covers the opening of the finger airbag 72 to surround the finger, forming an airbag enclosure that can cover the finger. Figure 2 , Figure 4As shown, in this embodiment, the cover airbag 71 is disposed on the top of the inner shell 2 and in front of the upper airbag 5, and the finger airbag 72 is disposed on 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.

[0031] Each airbag can be made of TPU material, which facilitates production and enhances durability. The airbags form chambers for gas expansion and contraction. The finger airbag 7 is not connected to the upper airbag 5 and the lower airbag 6, and can be independently controlled by inflating the finger airbag 7. This allows for selective adjustment to massage different parts of the hand. Each airbag is equipped with an inflation nozzle for easy control of the air valve to inflate the airbag. For the assembly of each airbag (upper airbag 5, lower airbag 6, and finger airbag 7) on the inner side of the inner shell 2, the back of the airbag can be glued to the inner wall of the inner shell 2. At the same time, the air nozzles on the back of each airbag are also fixed to the inner shell 2, providing a certain positioning function.

[0032] Specifically, the finger airbags 72 are formed by bending and shaping strip-shaped airbag sheets. The U-shaped finger airbags 72 have a certain supporting strength. The air cavities 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. 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 can abut against the inner wall 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.

[0033] 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. 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, which can then be shaped into a U-shape by pressing and bending, simplifying production costs and reducing 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 of the inner shell 2, which simplifies the overall installation structure and ensures the stability of the support during use.

[0034] Each finger airbag 72 has a first air nozzle 44 at its bottom. Each first air nozzle 44 is connected to an air valve 42 via a first air tube (not shown in the figure). Each finger airbag 72 can be independently controlled to inflate and deflate via a separate air valve. When a finger is not being massaged due to injury, the airbag 72 for that finger can be deactivated, improving usability. 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 via 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 to a first air tube and then to the air valve 42 for synchronous control.

[0035] 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.

[0036] 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 (not shown in the figure) 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.

[0037] 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.

[0038] like Figure 1 , Figure 3 As shown, 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.

[0039] like Figure 2As shown, a glove 8 for inserting a hand is also provided within the massage space, 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 portion 81 and a palm portion 82. The upper air bag 5 and lower air bag 6 correspond to the outer side of the palm portion 82 of the glove 8, and the finger air bag 72 corresponds to the outer side of the finger portion 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 portion 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.

[0040] When using this hand massager, 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, lower airbag 6 and finger airbag 7 to inflate and deflate simultaneously or independently, so as to achieve a full-range massage of the hand.

[0041] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
