Description

Technical Field

[0001] The invention relates to a massager, in particular to a limb massager used for massaging human arms. Background Art

[0002] At present, existing massage chairs are usually equipped with arm massage devices, which usually include an arm massage device frame and air bags, and the air bags are usually arranged in the arm massage device frame; the arm is placed between the air bags inside the arm massage device frame, and the arm is massaged by the expansion and contraction of the air bags.

[0003] However, most of the existing arm massage devices can only expand and contract in the direction perpendicular to the arm. The arm is only squeezed and massaged, the massage technique is single, and the massage experience is not ideal. In addition, the arm massage device is usually fixed, that is, fixed on the armrest of the massage chair, and the size is large. When people need to massage their arms separately, they need to sit on the massage chair to do so, which is inconvenient to use. Summary of the invention

[0004] In view of the shortcomings of the existing arm massagers, the technical problem to be solved by the present invention is to provide an air pressure limb massager which is easy to use and has more diverse massage techniques.

[0005] In order to solve the above technical problems, the technical solution of the present invention is:

[0006] A limb massager comprises a hard shell, an air pump, an air valve and a massage air bag, wherein the massage air bag is built into the hard shell, the hard shell is an annular structure, the hard shell is provided with a through hole for accommodating a user's limb, the massage air bag is arranged in the through hole, the massage air bag is arranged around the inner side wall of the through hole, the massage air bag is connected to the air pump through the air valve, and the massage air bag can squeeze the user's limb when inflated and the expansion of the massage air bag is blocked by the hard shell.

[0007] Furthermore, the massage airbag also includes a first airbag, which adopts a multi-layer airbag stacking structure, and the multi-layer airbags are arranged and distributed in a stepped manner along the inner wall of the through hole.

[0008] Furthermore, the massage airbag also includes a second airbag, which adopts a multi-layer airbag stacking structure. The multi-layer airbags are arranged in a stepped manner along the inner wall of the through hole. The first airbag and the second airbag are spaced apart from each other and are connected to the air pump through an air valve respectively; the extension direction of the multi-layer airbags on the second airbag is opposite to the extension direction of the multi-layer airbags on the first airbag and are inflated synchronously or asynchronously.

[0009] In another step, the first layer of the multi-layer airbag of the first airbag or the second airbag is connected to the air valve, and the other layers of the multi-layer airbag are arranged on the first layer and the lengths of the other layers gradually decrease in the direction away from the first layer.

[0010] Furthermore, the number of the first airbags is two, and the stepped arrangement direction of the multi-layer airbags of the two first airbags is the same; the number of the second airbags is two, and the stepped arrangement direction of the multi-layer airbags of the two second airbags is the same.

[0011] Furthermore, the massage airbag also includes a third airbag. The third airbag adopts a double-layer airbag structure, and the third airbag is arranged around the inner wall of the through hole.

[0012] Compared with the prior art, the limb massager of the present invention has at least two groups of airbags for inflation, wherein the multiple layers of airbags of the first airbag and the second airbag are arranged in a stepped manner, and the length of each layer of airbags gradually shortens from the first layer of airbags.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0024] Example 1, reference Figures 2 to 8 A limb massager shown in the figure can be used for arm or leg massage. The limb massager includes a hard shell 1, an air pump 12, an air valve 13, a massage air bag 2, a rechargeable battery, etc. The hard shell 1 is an annular structure, including a through hole 11 for accommodating the user's limbs, and the massage air bag 2 is built in the hard shell 1. The massage air bag 2 is arranged in the through hole 11 and the massage air bag 2 is arranged around the inner side wall of the through hole 11. The massage air bag 2 is connected to the air pump 12 through the air valve 13, and the air pump 12 inflates or deflates the massage air bag 2 through the air valve 13. When the massage air bag 2 is inflated, its expansion direction will be blocked by the hard shell 1, and the user's limbs will be squeezed in the opposite direction. The opening and closing of the air valve 13 is controlled by a circuit program, and the massage air bag 2 can be controlled to squeeze and massage the limbs.

[0025] Figure 3 Schematic diagram of horizontal deployment of massage airbag 2 in Embodiment 1. Figure 3 The plastic sheet 24 of the massage airbag 2 is provided with a first airbag 21 and a second airbag 22. The first airbag 21 is formed by stacking three layers of airbags, which are arranged in a stepped stacking arrangement in the horizontal direction; the second airbag 22 is also formed by stacking three layers of airbags, which are also arranged in a stepped stacking arrangement in the horizontal direction. When the massage airbag 2 surrounds the inner side wall of the through hole 11 of the hard shell 1, the multiple layers of airbags of the first airbag 21 and the second airbag 22 are arranged in a stepped arrangement along the inner side wall of the through hole 11.

[0026] The first layer of airbags in the multi-layer airbags of the first airbag 21 or the second airbag 22 is connected to the air valve 13, the second layer of airbags is connected to the first layer of airbags, and the third layer of airbags is connected to the second layer of airbags. Starting from the first layer of airbags, the lengths of the second layer of airbags and the third layer of airbags gradually decrease in the direction away from the first layer of airbags. The air pump 12 inflates the first layer of airbags through the air valve 13, and the third layer of airbags is first inflated and squeezes the limbs first; then the second layer of airbags is inflated and squeezes the limbs, and then the first layer of airbags is inflated and squeezes the limbs last.

[0027] The first air bag 21 and the second air bag 22 are arranged on the plastic sheet 24 of the massage air bag 2 at a distance from each other. The first air bag 21 and the second air bag 22 are connected to the air pump 12 through an air valve 13 for inflation, which is equivalent to the first air bag 21 and the second air bag 22 being supplied with air separately. There are two first air bags 21, which are respectively arranged on the upper part of the upper surface of the plastic sheet 24 of the massage air bag 2. The three layers of air bags are arranged in the same horizontal step-like direction, from high to low. When the air pump 12 inflates the first air bag 21 through the air valve 13, the saturation direction of the three layers of air bags of the first air bag 21 is from left to right. Wrap it around the inner wall of the through hole 11 of the hard shell 1 of the massager, the limbs will have a twisting massage effect. Similarly, there are two second air bags 22, which are respectively arranged at the lower part of the upper surface of the plastic sheet 24 of the massage air bag 2. The three layers of air bags are arranged in the same horizontal step-like direction, from low to high. When the air pump 12 inflates the second air bag 22 through another air valve 13, the air bag saturation direction is from right to left, and it is surrounded by the inner wall of the through hole 11 of the hard shell 1 of the massager, and the limbs will have a twisting massage effect in the opposite twisting direction to the first air bag 21. Two different air valves 13 are used to control the synchronous inflation or asynchronous inflation of the first air bag 21 and the second air bag 22, respectively, to generate a massage effect in which the first air bag 21 and the second air bag 22 are twisted simultaneously or asynchronously.

[0028] The massage airbag 2 also includes a third airbag 23, which is used for squeezing and massaging the limbs and expanding to fill the space between the limbs and the inner wall of the through hole 11. In this embodiment, the massage airbag 2 has four third airbags 23, which are respectively arranged at intervals on the lower surface of the plastic sheet, and the four third airbags 23 are arranged around the inner wall of the through hole 11. The third airbag 23 adopts a double-layer airbag structure so that the third airbag 23 can expand rapidly longitudinally, so that the massage airbag 2 can quickly squeeze the limbs.

[0029] The limb massager of the first embodiment uses three air valves 13 to control the first air bag 21, the second air bag 22 and the third air bag 23 respectively. When the limb massager is inflated for massage, the lower part of the limb massager corresponds to the position of the first air bag 21 on the inner wall of the through hole 11, and the massage effect of the first air bag 21 is to drive the lower part of the limb to twist counterclockwise; the upper part of the limb massager corresponds to the position of the second air bag 22 on the inner wall of the through hole 11, and the massage effect of the second air bag 22 is to drive the upper part of the limb to twist clockwise. When only the third air bag 23 is inflated, the third air bag 23 expands to fill the space between the limb and the hard shell 1, squeezing the limb for massage.

[0030] Embodiment 2, in addition to having all the features of embodiment 1, the limb massager also includes a shell 3 surrounding the hard shell 1. The shell 3 is composed of a front shell component 31 and a rear shell component 32 that are buckled together, and a control button 33 is provided on the shell 3. The shell 3 is spaced apart from the hard shell 1 to form a storage space for accommodating the air pump 12 and the air valve 13, the control circuit board, and the battery. The upper part of the storage space is provided with an upper ring component 4, which serves to decorate and seal the upper opening of the storage space. The lower part of the storage space is provided with a lower ring component 5, which serves to seal the lower opening of the storage space.

[0031] The limb massage device of this embodiment may further include a base 6 for placing the limb massage device body and charging the limb massage device, and the charging base 6 has a built-in charging component.

[0032] When the limb massager of this embodiment is used to massage the arm, the button 33 is activated to control the air pump 12 and the three air valves 13 to inflate the massage air bag 2, and the first air bag 21 is inflated and expanded to form a massage air bag 2 in the lower arm space. Figure 5 The opposite staggered arrangement shown in the figure, the second air bag 22 is inflated to form a space in the upper arm. Figure 6 The third airbag 23 is inflated and expanded in the space between the upper arm and the lower arm to form an embracing arrangement. Through the control program preset on the circuit board, the two first airbags 21 are inflated at the same time, forming a dislocated pressure on the lower arm; then the two second airbags 22 are inflated at the same time, forming a dislocated pressure on the upper arm. Figure 8 As shown, the first air bag 21 and the second air bag 22 are simultaneously offset and press the arm, producing a massage effect simulating the twisting and pressing of the human body's arm. Then, the air valve 13 controls the first air bag 21 and the second air bag 22 to deflate, and the third air bag 23 begins to inflate, achieving a massage effect of hugging the arm up and down. The first air bag 21, the second air bag 22 and the third air bag 23 are alternately inflated and deflated to form a variety of massage techniques.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
