Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a massage airbag, a massage pad, and a mattress. Background Technology

[0002] Existing massage airbags include a massage head, which is enclosed. The massage head inflates to increase air pressure, causing it to harden and deform to apply pressure to the user, thus creating massage stimulation. Because the air pressure inside the massage head gradually increases, the pressure gradually increases, making it impossible to apply pressure instantaneously. This results in insufficient pressure to meet user needs. Furthermore, the massage head needs to deflate to prepare for resuming massage stimulation, leading to a low frequency of pressure application and impacting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a massage airbag. The massage head is equipped with an air tube containing a hard ball and an exhaust port connected to the air tube. The hard ball blocks the air tube and accumulates high-pressure gas inside the airbag. This high-pressure gas can push the hard ball away from the air tube and form an impact airflow through the exhaust port. This not only effectively increases the instantaneous pressure, but also eliminates the need for exhaust operation during the decompression process, thereby increasing the frequency of pressure application and improving massage comfort.

[0004] The beneficial effects of this utility model are as follows: A massage airbag includes a bladder with an internal cavity. The top of the bladder has a massage structure, which includes a massage head positioned above the bladder, an air tube bridging the cavity and the massage head, and a rigid ball disposed within the air tube. The massage head has an upward-facing exhaust port. The cavity accumulates pressure when the rigid ball is embedded in the air tube, and when the rigid ball is pushed upwards out of the air tube, a massage-inducing impact airflow is generated and discharged through the exhaust port. The air tube is located inside the massage head, and a movable rigid ball is disposed within it. The exhaust port is located in the middle of the top wall of the massage head and communicates with the air tube. The rigid ball blocks the air tube and accumulates high-pressure gas within the bladder. Once the high-pressure gas reaches a preset pressure, it can push the rigid ball away from the air tube and generate an upward-flowing impact airflow through the exhaust port. This impact airflow acts on the user's surface, providing massage stimulation. This design effectively enhances the instantaneous pressure of the massage by utilizing the pressure accumulated and released within the bladder, and eliminates the need for venting during the pressure release process, thereby increasing the frequency of pressure application and improving massage comfort.

[0005] Preferably, the upper end of the trachea is provided with a flexible, upward-facing, funnel-shaped venting ring. The massage head includes a support ring, and the periphery of the flexible venting ring is bonded to the inner edge of the support ring. The flexible venting ring is positioned around the upper end of the trachea, and its periphery is connected to the inner edge of the support ring, ensuring the stability of the flexible venting ring. The flexible venting ring guides the hard ball back into the trachea. The flexible venting ring and the trachea can be independently machined and bonded together, or they can be integrally formed.

[0006] Preferably, the support ring is a spherical shape with an upward bulge in the center. The massage head includes an upper baffle located in the center of the support ring, and the exhaust port is located in the center of the upper baffle. The periphery of the upper baffle is connected to the inner edge of the support ring. The upper baffle and the flexible venting ring form a venting cavity for the outward discharge of the inflation airflow. After the impact airflow passes through the venting cavity, it is transported upward through the exhaust port and forms a massage stimulation through impact. The upper baffle is independently machined and connected to the inner edge of the support ring, forming a venting cavity with the flexible venting ring. This cavity serves to accommodate the hard ball after it leaves the trachea, ensuring that the airflow inside the bladder can form an impact airflow through the exhaust port. It also restricts the movement of the hard ball, and the flexible venting ring guides the hard ball back into the trachea.

[0007] Preferably, the support ring covers the trachea and surrounds the top wall of the bladder to form an annular support cavity, with the periphery of the support ring adhering to the top wall of the bladder. The support cavity inflates and shapes the trachea and flexible deflation ring, ensuring the rigid sphere can switch back and forth between the trachea and the deflation cavity. The support cavity is filled with an elastic material. The support cavity can be either a closed structure isolated from the outside or a structure connected to the bladder. When a closed structure is used, the air pressure inside the support cavity remains constant, and the elastic material maintains its contour, preventing collapse. When a structure connected to the bladder is used, the support cavity inflates and deflates synchronously with the bladder, providing effective support by increasing the air pressure inside the support cavity and maintaining its contour after deflation, also preventing collapse.

[0008] Preferably, the lower end of the trachea is provided with a flexible, downward-facing, funnel-shaped inflatable ring. An air outlet is formed in the top wall of the bladder. The flexible inflatable ring is adhered to the top wall of the bladder, allowing the trachea to communicate with the bladder through the air outlet. The flexible inflatable ring deforms to match and adhere to the top wall of the bladder, thus positioning the lower end of the trachea to ensure it aligns with and communicates with the air outlet. It also effectively improves the sealing effect, ensuring that high-pressure air inside the bladder can be discharged through the trachea.

[0009] Preferably, the trachea is a rigid tube, and the trachea is cylindrical. A limiting ring is formed at the lower end of the trachea by a narrowing. The diameter of the rigid ball is smaller than the diameter of the trachea, so that the rigid ball, inserted into the trachea from top to bottom, is held in place by the limiting ring. The rigidity of the trachea ensures that the rigid ball will not become stuck due to local deformation of the trachea, that the rigid ball can slide along the trachea and switch between opening and closing, and that the trachea always maintains a vertically upward orientation, ensuring that airflow is directed towards the exhaust port and effectively reducing airflow loss. The smaller diameter of the rigid ball ensures that it can move along the trachea axis, and the limiting ring at the lower end of the trachea restricts the movement of the rigid ball, preventing it from falling into the capsule.

[0010] Preferably, the upper section of the trachea forms a guiding channel. Driven by the impact airflow, the rigid ball accelerates upwards along the guiding channel and, after detaching from the trachea, impacts the top wall of the venting chamber to provide massage stimulation. The rigid ball can accelerate within the guiding channel and, after entering the venting chamber, impacts the upper baffle to apply massage stimulation to the user's surface, enhancing the massage experience in conjunction with the impact airflow. The venting chamber acts to prevent the rigid ball from dislodging and guides its repositioning, facilitating the re-accumulation of high-pressure air in the bladder after the ball returns to the trachea.

[0011] Preferably, the bladder includes at least two vertically stacked and interconnected cavities. The bottom of the bladder has an air nozzle communicating with the outside, allowing for adjustable air pressure within the bladder and providing an air source for generating an impact airflow. The interconnected cavities and synchronized air pressure adjustment provide stable support for the user, ensuring the massage head is raised to a preset height, thus facilitating a close fit between the massage head and the user's surface.

[0012] A massage pad includes a plurality of massage airbags arranged in a matrix. By deploying the massage airbags in a sheet, all areas of the user's surface can be stimulated by the massage head, thereby improving massage comfort.

[0013] A mattress includes a mattress body on which a massage pad is laid on top. The mattress body provides effective support for the massage pad, ensuring that the massage pad can stably apply upward massage stimulation, providing a comfortable massage stimulation for the user and effectively improving massage comfort.

[0014] The beneficial effects of this utility model are as follows: The air tube is set inside the massage head, and a movable hard ball is provided inside the air tube. The exhaust port is located in the middle of the top wall of the massage head and is connected to the air tube. The hard ball blocks the air tube and accumulates high-pressure gas in the bladder. After the high-pressure gas reaches the preset pressure, it can push the hard ball away from the air tube and form an upward impact airflow through the exhaust port. The impact airflow acts on the user's surface and forms a massage stimulation. It can effectively increase the instantaneous force of the pressing action by using the action of accumulating pressure in the bladder and releasing it in a concentrated manner. It also eliminates the need for exhaust operation by using the pressure release process, thereby increasing the frequency of the pressing action and improving the massage comfort.

[0022] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1:

[0024] This embodiment provides a massage airbag.

[0025] like Figure 1 , 2The massage airbag shown in Figure 3 includes a bag body 1 with an internal cavity. The top of the bag body 1 is provided with a massage structure. The massage structure includes a massage head disposed above the bag body 1, an air tube 2 spanning between the bag cavity and the massage head, and a rigid ball 3 disposed inside the air tube 2. The top of the massage head has an upward-facing exhaust port 4. The bag cavity accumulates pressure when the rigid ball 3 is embedded in the air tube 2, and forms a massage impact airflow that is discharged through the exhaust port 4 when the rigid ball 3 is pushed upward away from the air tube 2. The air tube 2 is installed inside the massage head, and a movable hard ball 3 is provided inside the air tube 2. The top of the massage head is provided with an exhaust port 4 that communicates with the air tube 2. The hard ball 3 is used to block the air tube 2 and accumulate high-pressure gas in the bladder 1. After the high-pressure gas reaches the preset pressure, it can push the hard ball 3 away from the air tube 2 and form an upward impact airflow through the exhaust port 4. The impact airflow acts on the user's surface and forms a massage stimulation. It can effectively increase the instantaneous force of the pressing action by using the action of accumulating pressure in the bladder 1 and releasing it in a concentrated manner. It also eliminates the need for exhaust operation by using the pressure release process, thereby increasing the frequency of the pressing action and improving the massage comfort.

[0026] In this embodiment, massage stimulation is obtained by inflating the bladder 1 to provide massage services to the user. Specifically, when the massage airbag 11 is in an uninflated, idle state, the bladder 1 is not inflated, and the hard ball 3 is stuck at the bottom of the air tube 2 and blocks the air outlet 10 by its own weight. When the massage airbag 11 is inflated, the bladder 1 receives external gas and expands. Since the air outlet 10 is blocked by the hard ball 3, the gas is confined within the bladder cavity. The height of the massage head will rise as the bladder 1 expands and fit closely to the user's surface. The air pressure in the bladder cavity will increase with continuous inflation. When the air pressure in the bladder cavity reaches a preset value, it will push the hard ball 3 upward along the air tube 2 to the venting chamber 7, so that the high-pressure air in the bladder cavity can pass through the air outlet 10, the air tube 2, the venting chamber 7 and the exhaust port 4 in sequence to form an impact air pressure. The impact air pressure strikes the user's surface and forms a massage stimulation. When the air pressure inside the bladder decreases due to the outward flow of air, the rigid ball 3 falls back to the bottom of the trachea 2 under its own gravity and blocks the air vent again, so that the bladder can store air through closure, preparing for the next jet of impact air.

[0027] In this embodiment, the bladder continuously receives high-pressure air to ensure that the inflation airflow is output at the same interval. The higher the pressure of the high-pressure air, the shorter the time required for the bladder to store air, the shorter the time interval between two adjacent airflow impacts, and the higher the frequency of massage stimulation, effectively improving massage comfort. Furthermore, the intensity of the pressure exerted by the inflation airflow on the user is related to the mass of the hard ball 3. The greater the weight of the hard ball 3, the higher the air pressure stored in the bladder, resulting in a greater pressure for the impact airflow. This increases the intensity of the massage stimulation by increasing the pressure exerted, effectively improving massage comfort.

[0028] In this embodiment, the air tube 2 is a rigid straight tube with a vertical axis. The upper end of the air tube 2 has a flexible venting ring 5 that is flared upwards, and the lower end of the air tube 2 has a flexible inflatable ring 9 that is flared downwards. The massage head includes a support ring 6 and an upper baffle 14 located in the middle of the support ring 6. Figure 4 As shown, the upper end of the trachea 2 is sealed to the inner edge of the flexible venting ring 5. The outer edge of the flexible venting ring 5, the periphery of the upper baffle, and the inner edge of the support ring 6 are mutually sealed and bonded, respectively forming a venting cavity 7 and a support ring cavity surrounding the venting cavity 7 and the trachea 2. The lower end of the trachea 2 is sealed to the inner edge of the flexible inflation ring 9. The flexible inflation ring 9 is bonded to the top wall of the bladder body 1 so that the lower end of the trachea 2 communicates with the ventilation hole. The trachea 2, the flexible venting ring 5, and the flexible inflation ring 9 can be produced and bonded together independently, or they can be integrally formed (e.g., Figure 5 All of the above (as shown) should be considered as specific implementations of this embodiment.

[0029] In this embodiment, the periphery of the flexible venting ring 5 is adhered to the inner edge of the supporting ring 6, forming a venting cavity 7 for the outward discharge of the inflation airflow. The venting cavity 7 connects the upper end of the air tube 2 and the exhaust port, both restricting the movement of the rigid ball 3 to prevent it from detaching and ensuring that the rigid ball 3 can fall back into the air tube 2 along the side wall of the venting cavity 7, and guiding and diffusing the high-pressure airflow from the bladder cavity to ensure that the airflow can be delivered outward through the exhaust port.

[0030] In this embodiment, the support ring 6 is a spherical shape with an upward bulge in the center. The exhaust port 4 is located in the center of the upper baffle 14. The periphery of the upper baffle 14 is connected to the inner edge of the support ring 6. The impact airflow is delivered upward through the exhaust port 4 and forms a massage stimulation through impact. The support ring and the upper baffle are bonded together to form a spherical surface, which can not only fit closely to the user's surface, but also provide comfortable resistance and support, thus improving the user's comfort.

[0031] In this embodiment, the support ring 6 covers the trachea 2 and surrounds the top wall of the bag body 1 to form an annular support cavity 8. The periphery of the support ring 6 is adhered to the top wall of the bag body 1. The outer edge of the support ring 6 is adhered to the top wall of the bag body 1 to form an annular support cavity 8. The support cavity wraps around the trachea 2 and the rigid ball 3, effectively reducing the foreign body sensation and maintaining the posture and contour of the trachea 2 and the venting cavity 7 for normal use.

[0032] In this embodiment, an air outlet 10 is formed on the top wall of the bladder body 1, and the flexible inflatable ring 9 is adhered to the top wall of the bladder body 1 so that the air tube 2 communicates with the bladder body 1 through the air outlet 10. The flexible inflatable ring 9 is adhered to the top wall of the bladder body 1 in the area surrounding the air outlet 10, which serves to position the air tube 2 and ensures a sealed connection between the air tube 2 and the air bladder. There can be multiple air outlets 10 arranged closely together to ensure that each air outlet 10 communicates with the lower end of the air tube 2. In addition, by reducing the diameter of each air outlet 10, it is easier to seal it with a hard ball 3.

[0033] In this embodiment, the trachea 2 is a rigid tube, and the trachea 2 is cylindrical. The lower end of the trachea 2 has a constricted periphery forming a limiting ring. The diameter of the rigid ball 3 is smaller than the diameter of the trachea 2, so that the rigid ball 3, inserted into the trachea 2 from top to bottom, is locked and limited by the limiting ring. The inner diameter of the trachea 2 is slightly larger than the diameter of the rigid ball 3, which effectively reduces the friction of the rigid ball 3 during movement, facilitates the movement of the rigid ball 3 along the axis of the trachea 2, and also effectively reduces the gap between the rigid ball 3 and the inner wall of the trachea 2. This ensures that the high-pressure air output through the air outlet 10 can effectively drive the movement of the rigid ball 3, thereby increasing the massage stimulation intensity by increasing the air pressure of the impact airflow.

[0034] In this embodiment, the upper section of the trachea 2 forms a guiding channel. The hard ball 3, driven by the impact airflow, accelerates upward along the guiding channel and, after detaching from the trachea 2, impacts the top wall of the venting chamber 7 to create a massage stimulation. By increasing the length of the guiding channel to provide directional guidance for the hard ball 3, it is ensured that the hard ball 3 is ejected upward under the push of high-pressure air and impacts the upper baffle 14. The upper baffle 14 transmits the impact force to the user, thus forming a second type of massage stimulation different from the impact airflow. This should also be considered a specific implementation of this embodiment.

[0035] In this embodiment, the bladder 1 includes at least two vertically stacked and interconnected cavities. The bottom of the bladder 1 is provided with an air nozzle 13 communicating with the outside, allowing for adjustable air pressure within the bladder 1 and providing an air source for generating impact airflow. By providing multiple cavities, the height of the bladder 1 is increased, thereby improving the fit between the massage head and the user's surface. The interconnected cavities, connected to an external air source via the air nozzle 13, allow for adjustable air pressure within the cavities, enabling the massage head to generate massage stimulation as needed.

[0036] Example 2:

[0037] Compared to Embodiment 1, this embodiment provides a massage pad.

[0038] like Figure 6The massage pad shown includes a plurality of massage airbags 11 arranged in a matrix. The number of massage heads is increased by densely arranging the massage airbags 11, thereby facilitating the provision of massage stimulation to various areas of the user's surface.

[0039] The other structures and effects of the massage airbag 11 described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0040] Example 3:

[0041] Compared to Embodiment 2, this embodiment provides a mattress.

[0042] A mattress includes a mattress body, on which a massage pad 12 is laid. The massage pad 12 is positioned on top of the mattress body, which provides support for the massage pad 12 to ensure that the massage heads can apply massage stimulation upwards, and also provides support for the user to ensure that the user's surface fits snugly against the top surface of the massage pad 12, thereby improving massage comfort.

[0043] The other structures and effects of the massage airbag 11 described in this embodiment are the same as those in Embodiment 2, and will not be repeated here.
