UTILITARIAN CONTENT

[0003] The utility model aims at providing a noise reduction formula car seat massage air pipe to solve the problem mentioned in the background art.

[0004] In order to realize the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] A noise reduction formula car seat massage air pipe, comprising a rubber tube, further comprising a supporting piece, the supporting piece is plastic material, the supporting piece comprises an inner tube and a supporting strip, the inner tube is arranged in the center of rubber tube, the inner tube is provided with a flow guide hole, the supporting strip is arranged in multiple and is circumferentially uniformly distributed and is connected to the outer side of inner tube, the supporting strip is supported in the inner wall of rubber tube, and the outer wall of inner tube is circumferentially distributed with a plurality of convex patterns arranged along the axial direction.

[0006] Further to the utility model, the supporting strip is arranged in three.

[0007] Further to the utility model, the left and right sides of the supporting strip are inclined surfaces, and the width of the end of the supporting strip close to the inner tube is greater than the width of the other end.

[0008] Further to the utility model, the rubber tube and the supporting piece are integrally extruded.

[0009] Further to the utility model, the rubber tube and the supporting piece are separately arranged, and the outer end surface of the supporting strip is abutted in the inner wall of rubber tube.

[0010] The utility model has the advantages of:

[0011] The support piece is arranged in the rubber pipe to support, avoids being crushed and unable to ventilate in the working process, the support piece adopts the structural design of the inner tube and the support strip, the inner tube is also provided with the flow guide hole to guide the gas, in the ventilation process, the airflow is divided into multiple areas by the support piece and is guided, avoids the airflow passing through the larger plane and produces the abnormal sound, the setting of the inner tube also separates the support plates, avoids the inner end of the support plate contacting and forming the deeper V-shaped groove body, can further realize the noise reduction function, and the outer wall of the inner tube of the design is provided with the convex grain along the axial direction, improves the roughness, and the airflow also plays a noise reduction function in the face. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 It is the overall structure diagram of the utility model. DETAILED DESCRIPTION

[0013] The utility model is further explained below in combination with the drawings:

[0014] As Figure 1 Indicated, a kind of noise reduction formula automobile seat massage air pipe, including rubber pipe 1, also include support piece 2;The support piece 2 is plastic material;The support piece 2 includes inner tube 21 and support strip 22;The inner tube 21 is arranged in rubber pipe 1 center;The inner tube 21 is equipped with flow guide hole 211;The support strip 22 is arranged multiple and is connected with the circumferential uniform distribution of inner tube 21 outer side;The support strip 22 is supported in the inner wall of rubber pipe 1;The outer wall of the inner tube 21 is circumferentially distributed and is equipped with several convex grains 212 along the axial direction setting;The support piece 2 is arranged in rubber pipe 1 in the design to support, avoids being crushed and unable to ventilate in the working process, the support piece 2 adopts the structural design of the inner tube 21 and the support strip 22, the inner tube 21 is also provided with flow guide hole 211 to guide the gas, in the ventilation process, the airflow is divided into multiple areas by the support piece 2 and is guided, avoids the airflow passing through the larger plane and produces the abnormal sound, the setting of the inner tube 21 also separates support plate, avoids the inner end of support plate contacting and forming the deeper V-shaped groove body, can further realize the noise reduction function, and the outer wall of the inner tube 21 of the design is provided with the convex grain 212 along the axial direction, improves the roughness, and the airflow also plays a noise reduction function in the face.

[0015] In the design, the support strip 22 is arranged three, according to actual demand can be arranged more support strip 22, after testing, setting three structure is more optimal, can play stable support effect, in combination with the structure of the design also can play good noise reduction effect, and also avoid too many support strip 22 to occupy too much space and affect airflow delivery.

[0016] The left and right sides of the support strip 22 are inclined, and the width of the end of the support strip 22 close to the inner tube 21 is greater than the width of the other end, which has high stability.

[0017] The rubber pipe 1 and the supporting piece 2 can be integrally extruded or separately formed, and after the separate formation, the supporting piece 2 is inserted into the rubber pipe 1, and the supporting effect is realized by the outer end of the supporting strip 22 abutting against the inner wall of the rubber pipe 1, and the embodiment adopts the separate formation mode.

[0018] The above description is not intended to limit the technical scope of the present application, and any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application still belong to the technical scope of the present application.
