Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic massage and relates to a massage air bag structure. Background Art

[0002] Pneumatic massage seats are designed according to ergonomics, with a pneumatic massage system added to the seat. Air is provided by an air pump, and there are multiple air bags in the seat back. The inflation and deflation of each air bag are controlled by an air valve, and then the expansion and contraction of each air bag are controlled to achieve the massage function, thereby protecting the lumbar spine and relieving fatigue. For example, a Chinese patent discloses a pneumatic bladder for massage [authorization announcement number CN220996205U], including at least one massage air bag body, the massage air bag body is formed by sealing and connecting the upper sheet and the lower sheet to form a hollow structure, and the massage air bag body is provided with an air inlet for inflation and deflation.

[0003] When the pneumatic bladder is inflated, the massage bladder can only expand in a specific direction, the massage range is small, and the function of rotational massage cannot be achieved. Utility Model Content

[0004] The utility model aims to solve the above problems in the prior art and proposes a massage air bag structure which can realize the rotation massage function.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] The massage air bag structure includes a main air bag, which is connected to a main air pipe for inflation and deflation, the upper side of the main air bag is connected to a percussion convex body, the lower side of the main air bag is connected to a plurality of pneumatic direction control components distributed in a circular array along the center line of the main air bag, and the pneumatic direction control components are connected to a secondary air pipe for inflation and deflation.

[0007] Since several pneumatic direction control components are connected to the lower side of the main air bag, a wide range massage and rotation massage effect of tapping the convex body can be achieved through different inflation and deflation sequences. The main air pipe and the auxiliary air pipe are used to connect the air source and are controlled by the air valve.

[0008] In the above massage airbag structure, the main airbag is a hollow structure formed by sealingly connecting a first upper sheet and a first lower sheet, the knocking convex body is connected to the center of the first upper sheet, and a plurality of pneumatic control components are connected to the first lower sheet.

[0009] The first upper sheet and the first lower sheet are circular sheets, the main air pipe extends radially along the main air bag, the first upper sheet and the first lower sheet can be attached together when deflated, and the knocking convex body is centrally arranged on the first upper sheet.

[0010] In the above-mentioned massage airbag structure, the percussion convex body is a hollow structure formed by sealing and connecting a second upper sheet and a second lower sheet. The second lower sheet is connected to the first upper sheet, and a first ventilation hole is provided at the connection.

[0011] The outer diameter of the percussion convex body is smaller than that of the main airbag. When the main airbag is inflated through the main air pipe, the percussion convex body can be inflated simultaneously through the first ventilation hole. When deflating, the main airbag and the percussion convex body deflate simultaneously, and the volume is small after deflation.

[0012] In some other structural forms, the percussion convex body is a solid massage convex body.

[0013] In the above-mentioned massage airbag structure, the pneumatic direction control assembly includes a secondary airbag. The secondary airbag is a hollow structure formed by sealing and connecting a third upper sheet and a third lower sheet. The third upper sheet is connected to the first lower sheet of the main airbag. The outer diameter of the secondary airbag is smaller than that of the main airbag.

[0014] In the above-mentioned massage airbag structure, the pneumatic direction control assembly includes at least two secondary airbags. The third lower sheet of the upper secondary airbag is connected to the third upper sheet of the lower secondary airbag, and a second ventilation hole is provided at the connection. The third upper sheet of the uppermost secondary airbag is connected to the first lower sheet of the main airbag.

[0015] In the above-mentioned massage airbag structure, the secondary air pipe is connected to the lowermost secondary airbag. The secondary air pipe extends radially along the lowermost secondary airbag. When deflating, multiple secondary airbags in the same pneumatic direction control assembly deflate simultaneously, and the volume of the pneumatic direction control assembly is small after deflation.

[0016] In the above-mentioned massage airbag structure, there are at least two main airbags. The first lower sheet of the upper main airbag is connected to the first upper sheet of the lower main airbag, and a third ventilation hole is provided at the connection. The percussion convex body is connected to the first upper sheet of the uppermost main airbag. The telescopic distance of multiple main airbags is large after inflation and deflation.

[0017] In the above-mentioned massage airbag structure, the main air pipe is connected to the lowermost main airbag. The main air pipe extends radially along the lowermost main airbag. When deflating, several main airbags deflate simultaneously, and the volume of the main airbag is small after deflation.

[0018] Compared with the prior art, the massage airbag structure has the following advantages:

[0019] Since several secondary airbags are connected to the lower side of the main airbag, a wide range of massage and rotational massage effects of the percussion convex body can be achieved through different inflation and deflation sequences. The percussion convex body can increase the finger pressure of the massage, improve the comfort of the user, and has a small overall volume and low cost. Description of the Drawings
