Description

Technical Field

[0001] The utility model relates to the technical field of massage pads, and particularly relates to a stretching pad. Background Art

[0002] The waist and back are the parts of the human body that exert the most force, providing support for the human body and protecting the spine. They are the parts most prone to strain and trauma. For people who sit for a long time or engage in heavy physical labor, the waist and back bear more pressure, and the muscles may be in a tense state for a long time, which is likely to cause fatigue or injury in the waist and back, resulting in soreness and pain. As a physical therapy for quickly relieving fatigue, traditional Chinese massage can quickly relieve various discomforts of the body. However, the current number of professional masseurs cannot meet the gradually increasing massage needs and is expensive, nor can it meet the time and space requirements of consumers. Therefore, many massage products suitable for consumers to use at home have emerged, such as massage chairs, massage pillows, etc.

[0003] There are mainly two types of massage products. One is mechanical massage, which uses mechanical force to imitate the way of manual massage, such as kneading, pinching, pounding, hitting, etc., acting on the human body. Mechanical massage has a greater intensity, is prone to cause muscle damage, has a strong foreign body sensation, and poor comfort. The other is pneumatic massage. Compared with mechanical massage, pneumatic massage is more gentle, can effectively relax muscles, will not cause harm to muscles and bones, has better comfort, and no foreign body sensation. For example, the Chinese utility model patent with the publication number CN215350421U discloses a lumbar pillow, which adds airbags in the lumbar pillow and inflates and deflates the airbags to raise and lower the height of the lumbar pillow, thereby stretching and pulling the lumbar vertebrae and soothing the lumbar muscles. However, the massage techniques that this kind of massage lumbar pillow can simulate are single, which is the pulling method, and the effect is limited, and it cannot effectively relieve lumbar and back fatigue or injury.

[0027] The following further describes the present utility model in conjunction with the drawings and specific embodiments.

[0028] As Figures 1 to 5 shown, this embodiment discloses a stretching pad, which includes: a bottom support 1, a pad core 2, an airbag assembly 3, an air charging / discharging module 4, and a pad sleeve 5. The bottom support 1, the pad core 2, the airbag assembly 3, and the air charging / discharging module 4 are all installed inside the pad sleeve 5. Among them, the bottom support 1 is located at the bottom, the pad core 2 is arranged on the upper surface of the bottom support 1, the airbag assembly 3 is arranged on the upper surface of the pad core 2, and the air charging / discharging module 4 is arranged at the bottom of the pad core 2 and is connected to the airbag assembly 3 for charging and discharging the airbag assembly 3.

[0029] Specifically, the airbag assembly 3 of this embodiment includes: a plurality of airbags 31 arranged in sequence along the length direction of the pad core 2, and adjacent two airbags 31 are stacked in a staggered manner. By presetting the air charging / discharging sequence of each airbag 31, a variety of massage techniques can be simulated. For example: when simultaneously charging each airbag 31, each airbag 31 bulges and falls back upwards synchronously, pushing the waist and back for stretching; when charging each airbag 31 in sequence along a certain direction, each airbag 31 turns over and bulges in sequence along this direction, and a flat-pushing massage effect can be generated; when charging the next airbag 31, the previous airbag 31 discharges air, causing the airbags 31 to rise and fall one after another, generating a rolling massage effect. Compared with the straight up and down pressing method, since the airbags 31 of this embodiment are stacked on top of each other, during the inflation process of the airbag 31, the airbag 31 stacked above it will be flipped to one side, generating an obliquely upward thrust, or causing the airbag 31 above to generate an obliquely upward thrust during the inflation process, thereby generating a stroking effect.

[0030] To achieve a relatively ideal stroking effect, the overlapping width a of adjacent two airbags 31 preferably accounts for ~ of the width b of the airbag 31.

[0031] To facilitate the assembly and disassembly of the airbag assembly 3, prevent the airbag assembly 3 from shifting during use, and ensure the massage effect, a connecting member 32 can be added to limit each airbag 31, so that one side of the airbag 31 is connected to the connecting member 32, and the other side of the airbag 32 is stacked above the next airbag 32. Refer to Figure 6 , the arrow in the figure is the thrust direction. When charging each airbag 31 in the first direction, the inflated airbag 31 will flip the uninflated airbag 31 stacked above it upwards to an inclined state. When charging this uninflated airbag, an obliquely upward thrust will be generated, thereby generating a stroking effect. Refer to Figure 7 , the inflated airbag 31 will push up the inflated airbag 31 stacked above it, causing the inflated airbag to generate an obliquely upward thrust, thereby generating a stroking effect. The first direction is opposite to the second direction. Refer to Figure 8, inflate and deflate each airbag in sequence along a certain direction, and always keep one airbag in the wave crest position moving, thereby generating a wave-like rhythmic massage effect.

[0032] The upper surface of the cushion core 2 of this embodiment is adapted to the contour of the human waist and back, which can improve the fitting degree of the stretching pad and the waist and back, and improve the comfort and massage effect. Specifically, the upper surface of the cushion core 2 is mainly divided into three regions: the waist and back supporting surface 21 in the middle, and the side waist supporting surfaces 22 on both sides. The waist and back supporting surface 21 and the side waist supporting surfaces 22 on both sides are in a curved surface shape that conforms to the curve of the human waist and back. In order to improve the massage coverage rate, the airbag assembly 3 of this embodiment should at least cover the waist and back supporting surface 21.

[0033] The lower surface of the cushion core 2 of this embodiment is provided with a first installation groove 23, a second installation groove 24 and a third installation groove 25. The first installation groove 23 and the second installation groove 24 are respectively located below the side waist supporting surfaces 22 on both sides, and the third installation groove 25 is respectively communicated with the first installation groove 23 and the second installation groove 24. The upper surface of the cushion core 2 is provided with a number of fourth installation holes 26 communicated with the first installation groove 23. The side surface of the cushion core 2 is provided with a fifth installation hole 27.

[0034] The inflation and deflation module 4 of this embodiment includes: a first pipeline, a second pipeline (the first pipeline and the second pipeline are not shown in the figure), a first housing 45, a second housing 46, a main control board 41, and a battery 42, an air pump 43 and a number of three-way solenoid valves 44 respectively electrically connected to the main control board 41. Among them, the main control board 41, the battery 42 and each three-way solenoid valve 44 are all installed in the first housing 45, and the first housing 45 is installed in the first installation groove 23. The air pump 43 is installed in the second housing 46, and the second housing 46 is installed in the second installation groove 24. The first pipeline is installed in the third installation groove 25 for communicating each three-way solenoid valve 44 with the air pump 43. The second pipeline is installed in the fourth installation hole 26 for pairing and communicating each three-way solenoid valve 44 with each airbag 31 one by one. This embodiment divides the inflation and deflation module 4 into two main modules, which are respectively installed on both sides of the stretching pad. On the one hand, it facilitates the assembly of the stretching pad, and on the other hand, it balances the force on both sides of the stretching pad and is convenient to take.

[0035] Since the operation of the air pump 43 generates noise, in order to reduce the noise, a buffer support 49 and a sound insulation cotton 410 are also installed in the second housing 46 of this embodiment. The air pump 43 is installed in the second housing 46 through the buffer support 49. The buffer support 49 can reduce the vibration and noise generated by the air pump 43 during operation, and the buffer support 49 can be made of rubber or silica gel materials.

[0036] In order to facilitate the use of the stretching pad and reduce the production cost, the inflation and deflation module 4 of this embodiment further includes: a key panel 47 and a label 48. The key panel 47 is installed in the fifth installation hole 27, and the label 48 is aligned with the key panel 47 and connected to the pad cover 5 to facilitate the user to operate the key panel 47 according to the label 48. To prevent the label 48 from shifting and affecting the operation, the label 48 of this embodiment can be connected to the key panel 47 by means of a buckle structure, glue, Velcro, etc. to ensure accurate positioning.

[0037] The cushion core 2 of this embodiment is made of a soft material, such as foam, latex and other materials, to improve the comfort of lying on the stretching pad. The bottom support 1 of this embodiment has a certain hardness and can be made of EVA material. The bottom support 1 has a certain supporting effect, which can prevent the stretching pad from being sunken and deformed when placed on a too soft mattress or a non-planar surface, thus affecting the use effect.

[0038] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims.
