Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-6, an embodiment of the invention provides a noise reduction structure for an air bag of a massage chair, which comprises a chair frame, a plurality of air bags, an air pump, an air pipe, a plurality of air valves 2 and an air release pipe 1, wherein the air bags and the air pump are arranged in the chair frame, the air bags and the air pump are communicated through the air pipe, an air vent part is arranged on the air valves 2, the air vent part is communicated with the air pipe to control the on-off of the air pipe between the air bags and the air pump, each air valve 2 is respectively provided with an air release port 21, and the air release port 21 is communicated with the air vent part;
the air release port 21 is respectively communicated with the air release pipe 1, an air release end 122 is arranged on the air release pipe 1, a silencing air tap 3 is arranged on the air release end 122, and the inner hole diameter of the silencing air tap 3 is smaller than the inner hole diameter of the air release pipe 1; when the air bag is deflated, the air flow is discharged after passing through the silencing air tap 3.
Therefore, the air bag air leakage air flow is not directly discharged into the air with large impact, but is discharged into the air after being buffered by the small-aperture silencing air nozzle, so that the air bag air leakage noise is greatly reduced, and meanwhile, the exhaust speed is improved by arranging a plurality of exhaust ends, and the user experience is further improved.
Further, in one example, the bleeder 1 further includes a plurality of air inlet pipes 11 and a main pipe 121, and the air inlet pipes 11 are vertically arranged and communicated with the main pipe 121; the inner aperture of the end, connected with the main pipe 121, of the air inlet pipe 11 is smaller than the inner aperture of the air release port 21, and the inner aperture of the end, connected with the air release port 2, of the air inlet pipe 11 is matched with the outer aperture of the air release port 21; the main pipe 121 is provided with an exhaust end 122, and each air inlet pipe 11 is connected with the air leakage port 21.
In a specific example, the muffler air tap 3 may be omitted, and the inner aperture of the air discharge end 122 is designed to be smaller than the inner aperture of the air discharge opening 21, so that the air discharge noise may be reduced, and the structural components may be reduced. In another embodiment, the inner aperture of the exhaust end 122 is smaller than the inner aperture of the end of the intake pipe 11 connected to the main pipe 121. Thus, the air leakage air flow is discharged from the exhaust end with smaller aperture through the air inlet pipe with smaller aperture, noise of the air leakage air flow is lower through two-stage noise reduction, and user experience is better.
In operation, the air flow from the air discharge port 21 enters the main pipe 121 via the air inlet pipe 11 and is discharged from each of the air discharge ends 122 on the main pipe 121, so as to reduce air discharge noise of the air bag.
Further, in one example, as shown in fig. 1 and 5, the main pipe 121 may be provided with 2 exhaust ports 122, and a plurality of exhaust ports 122 may be provided for rapid air release, and as an alternative, the inner aperture of the exhaust port 122 is smaller than the inner aperture of the air release port 21. Thus, the air inlet pipe 11 with the inner hole at one end connected with the main pipe 121 being smaller than the inner hole of the air valve air release port 21 can be adopted, and the inner hole at the air exhaust end 122 can be smaller than the inner hole of the air release port 21, so that noise generated by air release flow is reduced, and the air release device is flexible and changeable, and can improve user experience.
In one example, to further reduce the leakage noise, the inner aperture of the exhaust end 122 is smaller than the inner aperture of the end of the intake pipe 11 connected to the main pipe 121.
Further, in one example, as shown in fig. 1-3, the air valve 2 has a plurality of air release openings 21, each air release opening 21 corresponds to one air inlet pipe 11, and a plurality of air inlet pipes 11 are uniformly and vertically arranged on one side of the main pipe 121 and are communicated with each other. When all the air leakage ports 21 are in air leakage, the mutually communicated air inlet pipes 11 are not interfered with each other, but when one or a plurality of air leakage ports 21 are in air leakage, the air leakage interference exists between the mutually communicated air inlet pipes 11, so that steel balls 111 are arranged above the air leakage ports 21, the steel columns 111 are positioned in the air leakage pipes 1, and particularly, the diameters of the steel balls 111 arranged in the air inlet pipes 11 are larger than the inner diameters of the air leakage ports 21; the steel ball 111 floats up and down in the air release pipe 1, specifically in the air inlet pipe 11, under the action of air flow to open and close the air release port 21. Specifically, as shown in fig. 2, when the air release port 21A releases air, the air flow in the air bag pushes the steel ball 111 through the air release port 21A, so that the steel ball 111 floats in the air inlet pipe 11 under the action of the air flow, the air flow flows out from gaps around the steel ball 111 in the air inlet pipe 11 and flows into the air inlet pipe 11 corresponding to the air release port 21B, the air flow is prevented from being strung into the air bag corresponding to the air release port 21B because the air release port 21B is blocked by the steel ball 111, and after the air release port 21A releases air, the steel ball 111 does not push the air flow, and falls under the action of dead weight to block the air release port 21A, so that the steel ball is controlled under the action of the air flow, and the air release port is opened and closed.
Further, in one example, as shown in fig. 1-4, the muffler air tap 3 is a cylinder, and includes a first section of air pipe 31, a second section of air pipe 32, and a third section of air pipe 33, where the first section of air pipe 31 is disposed on the exhaust end 122, an outer aperture of the first section of air pipe 31 is adapted to an inner aperture of the exhaust end 122, an outer aperture of the second section of air pipe 32 is the same as an outer aperture of the exhaust end 122, and an inner aperture of the third section of air pipe 33 is smaller than an inner aperture of the first section of air pipe 31. This makes the connection of the muffler air tap 3 to the air discharge pipe 1 smoother. Wherein, the noise elimination air tap 3 is made of soft rubber material. Specifically, the optimal ratio of the inner pore diameter of the third section of air pipe to the inner pore diameter of the air valve air release pipe is determined according to experimental experience, wherein the ratio of the inner pore diameter of the third section of air pipe to the pore diameter of the air release port is smaller than 0.5, so that the noise reduction effect is optimal.
Further, in one example, to further reduce the leakage noise, the air bag noise reduction structure of the massage chair further includes an internal resistance sponge disposed in the noise elimination nozzle 3 and disposed in the second section air pipe 32 at a position close to the third section air pipe 33, the internal resistance sponge being used to prevent the air flow from directly striking the side wall of the third section air pipe 33. Wherein, the thickness of internal resistance sponge is less than 1 millimeter to improve the rate of leaking gas when reducing gasbag noise of leaking gas. The internal resistance sponge is not shown in the figure.
Further, in one example, the air bag noise reduction structure of the massage chair comprises a plurality of air bags and a plurality of air valves, wherein a plurality of bronchi are communicated with the air pipes, and the bronchi are respectively communicated with the plurality of air bags.
Further, in one example, the inner surface of the end of the air inlet pipe 11 connected to the air leakage port 21 is provided with a plurality of small protrusions; the contact surface between the first section of air pipe 31 and the exhaust end 122 is provided with a plurality of small protrusions to increase friction force, so as to avoid the falling off of the air inlet pipe 11 and the air valve release port 2, and the first section of air pipe 31 and the exhaust end 122 in the repeated release process.
Therefore, the air bag air leakage air flow is not directly discharged into the air with large impact, but is discharged into the air after being buffered by the small-aperture silencing air nozzle, the air inlet pipe or the air exhaust end, so that the air bag air leakage noise is greatly reduced, and the exhaust speed is improved by arranging a plurality of air exhaust ends, and the user experience is further improved.
