Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to a massage airbag, an air cushion and a massage airbag pillow. Background Art

[0002] Common massage airbag pillows adjust each massage airbag on the air cushion by inflating and deflating the air cushion inside, making the vertical height of each massage airbag change repeatedly between high and low, so as to form a massage stimulation applied to the user. The existing massage airbag is formed by laminating and fitting two upper and lower placement pieces. The two placement pieces each have a preset height in the vertical direction and form two upper and lower concave cavities that can be docked. After the two placement pieces are fitted, a complete cavity is formed by docking. The massage part of the airbag is arranged on the upper placement piece, and a sponge block is placed in the lower concave cavity. When the airbag deflates, the sponge block can maintain the contour shape of the airbag, control the volume change of the airbag and improve the comfort of the headrest. Since specific shape processing is required for both the upper and lower concave cavities, the structure is complex and the production cost is high. Summary of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model provides a massage airbag, an air cushion and a massage airbag pillow. The cavity of the massage airbag changes from the docking of the original upper and lower two cavities to a single cavity, greatly simplifying the cavity structure and effectively reducing the production cost of the airbag.

[0004] The technical solution adopted by the utility model to solve the technical problem: A massage airbag includes a bladder with an internal cavity. The bladder is made by peripherally fitting an upper placement piece and a lower placement piece stacked vertically. The upper placement piece and the lower placement piece enclose the cavity. A massage part is provided in the middle of the upper placement piece. When the bladder is inflated, the top wall of the bladder where the massage part is located bulges upward, forming an upward transmitted massage stimulation. The feature is that the upper placement piece bulges on the flatly extended lower placement piece. The bulging upper placement piece forms the side wall and the top wall of the bladder, and a concave cavity is formed on the side facing the lower placement piece as the cavity. The utility model makes the bladder by fitting the flatly extended lower placement piece and the bulging upper placement piece. The cavity of the bladder is only a single cavity formed on the side of the bulging upper placement piece, and there is no cavity design on the side of the lower placement piece, simplifying the structure of the bladder and reducing the production cost.

[0005] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: The peripheral edge of the top wall of the bladder forms a deformation ring groove surrounding the massage part through a depression. When the bladder is inflated, the deformation ring groove is radially pulled and bulges, and the massage part bulges upward. The deformation ring groove can generate a radially pulled deformation when the bladder is inflated, and gradually changes from the original depressed shape to flatten and then bulge. The massage part located inside the deformation ring groove also bulges to the highest point as the deformation ring groove deforms and bulges, transmitting the massage stimulation upward.

[0006] Preferably, the vertical cross-section of the deformation ring groove is in the shape of an arc sunken in the middle. The deformation ring groove in the shape of an arc has the characteristic of low noise during deformation, which can effectively reduce the impact on the user's sleep when the deformation ring groove works and deforms.

[0007] Preferably, an arc-shaped corner continuous around the circumference is formed between the inner peripheral edge of the deformation ring groove and the adjacent massage part and / or between the deformation ring groove and the side wall of the bladder. Using an arc-shaped corner continuous around the circumference between the inner peripheral edge of the deformation ring groove and the adjacent massage part, and between the outer peripheral edge of the deformation ring groove and the adjacent side wall of the bladder can further reduce the noise generated by the deformation of the air bladder during the inflation and deflation process of the air bladder.

[0008] The second object of the invention of the present utility model is to provide an air cushion using the massage air bladder, including a gasket and the massage air bladder and a trachea provided thereon. The massage air bladder is inflated and deflated through the trachea to drive the massage part to bulge upward to form a massage stimulation. The air cushion forms a massage stimulation for applying to the user through the massage air bladder provided thereon. As long as a sufficient number of massage air bladders are provided on the air cushion, different working positions for applying massage stimulation can be formed, and massage stimulation can be applied to each area in contact with the user's surface, improving the massage comfort. Each area formed by all the massage air bladders can apply massage stimulation to the user when the user makes body movement and changes positions, enhancing the use experience of the massage.

[0009] Preferably, the massage air bladders are arranged on the gasket in a matrix shape. The matrix distribution ensures that there are evenly distributed massage air bladders in each area, and the user can feel the same massage stimulation in different areas of the cushion body; the air bladders are connected and positioned through the gasket to achieve the preset matrix distribution.

[0010] Preferably, among the massage air bladders arranged in a matrix shape, the massage air bladders in the spaced rows are interconnected with each other, and the air cushion has two sets of air bladders that can be independently controlled for inflation and deflation. All the massage air bladders in the matrix are interconnected in the spaced rows to form two independent air bladder groups for inflation and deflation. Then, between the two air bladder groups, they can be combined and changed for inflation and deflation flexibly by means of alternating, simultaneous, or preset different time intervals, etc., to achieve the effects of diversified massage stimulation and enhanced massage experience.

[0011] Preferably, the air cushion includes an upper substrate and a lower substrate. The upper substrate and the lower substrate are vertically stacked and adhered to enclose the massage air bladder, the trachea, and the gasket. The upper and lower sheets of each air bladder can be processed on the same upper substrate and the same lower substrate respectively. By stacking and adhering the upper substrate and the lower substrate, a formed air cushion can be obtained, which simplifies the processing procedure and improves the processing efficiency at the same time.

[0012] A third object of the invention of the present utility model is to provide a massage airbag pillow using the air cushion, which comprises an air cushion, a pillow body for supporting the air cushion, and a control box for adjusting the air pressure in the air cushion. The control box is connected to the massage airbag through an air pipe to inflate and deflate the airbag body, and the airbag body forms a massage stimulation transmitted upward through inflation and deflation. During use, the control box adjusts the air pressure of the airbag body in the air cushion, and obtains the massage stimulation transmitted upward by controlling the deformation of the airbag body in the vertical direction, so as to provide a comfortable massage experience for the user.

[0013] Preferably, a sponge layer is stacked on the air cushion to reduce the amplitude of volume change of the airbag body during deflation. Through holes matching the position and quantity of the massage airbags are formed in the sponge layer. When the airbag is inflated, the top wall of the airbag body where the massage part is located bulges upward and protrudes from the upper end surface of the through hole. The pillow body includes a pillow core, an inner pillowcase and an outer pillowcase which are successively sleeved from the inside to the outside. The air cushion together with the sponge layer is supported in an inner pillowcase pocket with an opening arranged on the surface of the inner pillowcase. A speaker is embedded in the pillow core. The positions of the massage airbags correspond to the through holes in the sponge layer. When the massage airbag is inflated and deflated, the massage part on the top wall of the airbag body can still normally bulge and protrude from the upper end surface of the through hole to apply an upward massage stimulation. When the airbag is not working, the sponge layer can improve the flatness of the pillow surface, reduce the foreign body sensation to ensure sleep comfort; the sponge layer can also reduce the volume change of the airbag body to shorten the interval time of inflation and deflation, increase the massage stimulation frequency, and reduce the deformation amplitude of the airbag body to reduce noise and avoid affecting the user's sleep. The pillow body has a layered wrapping structure, which is conducive to maintaining hygiene and convenient for cleaning. The air cushion together with the sponge layer is supported in the inner pillowcase pocket with an opening, and the user can choose to install and use or remove it according to needs. The speaker can play music to help sleep, help the user relax and improve the sleep quality.

[0014] The beneficial technical effects of the present utility model: The airbag cavity of the massage airbag is only a single cavity formed on one side of the raised upper sheet, and there is no cavity design on the lower sheet side. The structure of the airbag body is simplified, and the production cost is reduced. Through the deformation ring groove and the continuous arc-shaped corners along the circumference, the noise generated by the deformation of the airbag is further reduced. The structure of the air cushion using the massage airbag and the massage airbag pillow using the air cushion are also simplified, and the production cost is reduced. Description of the Drawings

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation modes.

[0026] As Figure 1 shown, Embodiment 1 is a kind of massage airbag, including a bladder body 1 with a bladder cavity 4 arranged inside. The bladder body 1 is made by peripherally bonding an upper sheet 2 and a lower sheet 3 which are vertically stacked. The upper sheet 2 and the lower sheet 3 enclose the bladder cavity 4. A massage part 6 is arranged in the middle of the upper sheet 2. When the bladder body 1 is inflated, the top wall of the bladder body 1 where the massage part 6 is located bulges upward, forming an upward transmitted massage stimulation. Its feature is that the upper sheet 2 bulges on the flatly extended lower sheet 3. The bulging upper sheet 2 forms the side wall and the top wall of the bladder body 1, and a concave cavity is formed on the side facing the lower sheet 3 as the bladder cavity 4.

[0027] Since the bladder body is made by bonding a flatly extended lower sheet and a bulging upper sheet, only the single cavity formed on the side of the bulging upper sheet serves as the bladder cavity, and there is no cavity design on the side of the flat lower sheet. The structure of the bladder body is simplified, and the production cost of the airbag is reduced.

[0028] Preferably, a deformation ring groove 5 surrounding the massage part 6 is formed by depression at the peripheral edge of the top wall of the bladder 1. When the bladder 1 is inflated, the deformation ring groove 5 bulges after being radially pulled, and the massage part 6 bulges upward. The vertical cross-section of the deformation ring groove 5 is in an arc shape sunken in the middle. At the same time, an arc-shaped corner 7 continuous around the circumference is formed between the inner peripheral edge of the deformation ring groove 5 and the adjacent massage part 6 and / or between the deformation ring groove 5 and the side wall of the bladder 1.

[0029] When the bladder is inflated, the deformation ring groove generates radial tensile deformation and gradually tends to flatten and then bulge from the original depressed shape, driving the massage part inside the deformation ring groove to deform and bulge out to the highest point. After the inflation is in place, the bulged part of the airbag assumes the shape shown by the dotted line in the figure, transmitting the massage stimulation upward; after deflation, the airbag returns to the shape shown by the solid line in the figure. The design of the arc-shaped deformation ring groove and the arc-shaped corner are both for reducing the noise generated by the deformation of the airbag during the inflation and deflation process.

[0030] As Figures 2 to 8 shown, Embodiment 2 is an air cushion using the massage airbag described in Embodiment 1, including a gasket 9 and the massage airbag 11 and a trachea 10 provided thereon. The massage airbags 11 are arranged in a matrix on the gasket 9. The gasket 9 is provided with a plurality of through ventilation holes 15 distributed in a matrix at positions outside the massage airbags. The massage airbags 11 are inflated and deflated through the trachea 10 to drive the massage part 6 to bulge upward to form a massage stimulation.

[0031] The air cushion forms a massage stimulation for the user by arranging the massage airbags in a matrix. These massage airbags can form different working positions for applying the massage stimulation. Each working position has evenly distributed massage airbags to apply massage stimulation to each area in contact with the user's surface, improving the massage comfort. The different working positions formed by all the massage airbags can apply massage stimulation to the user when the user makes a body movement and changes positions, enhancing the use experience of the massage.

[0032] Preferably, among the massage airbags 11 arranged in a matrix, the massage airbags 11 in the spaced rows are interconnected. Thus, the air cushion has two sets of bladders 1 that can be independently controlled for inflation and deflation. The two sets of alternately arranged airbag groups can achieve various flexible inflation and deflation modes such as alternating, simultaneous, and preset different time interval combinations through independent control of inflation and deflation, so as to achieve diversified massage stimulations and enhance the massage experience.

[0033] Preferably, the air cushion includes an upper substrate 12 and a lower substrate 13. The upper substrate 12 and the lower substrate 13 are vertically stacked and adhered to enclose the massage airbag 11, the trachea 10, and the gasket 9. In actual use, the upper and lower sheets of all the bladders are respectively processed on the same upper substrate and the same lower substrate. Stacking and adhering the upper substrate and the lower substrate can obtain a formed air cushion, simplifying the manufacturing process and improving the production efficiency.

[0034] Figure 9As shown in the figure, Embodiment 3 is a massage airbag pillow, which includes an air cushion, a pillow body for supporting the air cushion, and a control box 14 for adjusting the air pressure in the air cushion. The air cushion is the air cushion described in Embodiment 2. The control box 14 is connected to the massage airbag 11 through an air pipe 17 to inflate and deflate the bladder 1 of the air cushion. The bladder 1 forms a massage stimulus transmitted upward through inflation and deflation. The pillow body includes a pillow core 21, an inner pillowcase 19, and an outer pillowcase 16 that are successively sleeved from the inside to the outside. A Bluetooth speaker 20 for wirelessly connecting an external mobile phone or player is embedded in the pillow core 21. A sponge layer 8 for reducing the volume change amplitude of the bladder 1 during deflation is stacked on the air cushion. Through holes 81 matching the position and quantity of the massage airbags 11 are formed in the sponge layer 8. When the airbag is inflated, the top wall of the bladder 1 where the massage part 6 is located bulges upward and protrudes from the upper end surface of the through hole 81. The air cushion together with the sponge layer 8 is supported in an inner pillowcase pocket 18 with an opening provided on the surface of the inner pillowcase 19.

[0035] The sponge layer can also provide elastic support through its own elasticity, avoiding the uncomfortable touch caused by the flattening of the massage airbag after deflation and improving the user experience of the massage airbag. The sponge layer bears pressure when the air pressure inside the bladder cavity drops, maintaining the contour shape of the bladder and preventing the bladder volume from deforming too much, which may lead to an extension of the inflation and deflation interval time. This helps to increase the frequency of the massage stimulus, and the reduced deformation amplitude of the bladder is beneficial for reducing noise, thereby reducing the impact on the user's sleep. The pillow body has a layered wrapping structure, which is conducive to maintaining the hygiene of the air cushion and facilitating cleaning. The air cushion and the sponge layer are stuffed in the inner pillowcase pocket with an opening, and the user can choose to use or remove them according to their own needs. The speaker embedded in the pillow core can play music to help sleep and improve the sleep quality.
