[0027] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0028] Reference Figures 1 to 4 , Figure 1 This is a perspective view of an application example of this utility model. Figure 2 This is the front view of an application example of this utility model. Figure 3 yes Figure 2 Sectional view along the BB direction. Figure 4 This is an exploded view of an application example of this utility model. This utility model provides a quick-connect structure for a detachable headrest with an air tube, including an air inlet 1 and an air guide 2. The air inlet 1 is disposed on the headrest guide sleeve 3, and the air guide 2 is disposed at the lower end of the headrest rod. The air guide 2 is connected to the air inlet 1. The air inlet 1 can be opened and closed. After the air guide 2 pushes open the air inlet 1, it opens the air inlet 1 to form an air passage. That is, the air inlet 1 introduces the air source, and then the air is supplied to the headrest through the air guide 2 disposed on the headrest rod. It is suitable for the air passage connection system of a detachable headrest equipped with a pneumatic massage function.

[0029] The air intake 1 includes an air guide valve 11, an air inlet 12, and an elastic component 13. The air inlet 12 is connected to the headrest guide sleeve 3. The air guide valve 11 is connected to the elastic component 13. The two ends of the elastic component 13 are respectively connected to the air guide valve 11 and the air inlet 12. The elastic component 13 can be embedded in the air guide valve 11. The elastic component 13 is preferably a spring. When the elastic component 13 is not under force, the air guide valve 11 seals the air passage. The air guide valve 11 presses and closes the air intake pipe through the elastic component 13. That is, when the headrest rod with the air guide 2 is not inserted into the headrest guide sleeve 3 with the air intake 1 and the air guide valve 11 is not opened, the air guide valve 11 seals the gas in the headrest guide sleeve 3. After the air guide 2 opens the air guide valve 11, the air intake 1 is opened to form an air passage. The air passage refers to the passage through which gas flows from the air intake 1 to the air guide 2. The air passage may be provided with sound-absorbing cotton (not shown). In one embodiment, the gas guide valve 11 is provided with a plurality of gas guide grooves 111, which are arranged along the outer periphery of the gas guide valve 11 to allow gas to flow more smoothly.

[0030] The air guide section 2 includes an air guide rod 21, an air outlet 22, and a sealing ring 23. The air outlet 22 is connected to the air guide rod 21, and the other end of the air outlet 22 is used to connect to an air pipe to supply air to the massage headrest. The sealing ring 23 is disposed on the air guide rod 21 to seal and prevent gas leakage after the air guide section 2 is inserted into the headrest guide sleeve 3 and the air passage is opened. The lower end of the air guide rod 21 is provided with a plurality of air guide holes 211 in a circumferential direction so that gas can flow to the air outlet 22 through the air guide holes 211. In one embodiment, the air guide rod 21 is provided with a plurality of airflow grooves 212 in a circumferential direction, and the air guide holes 211 are disposed on the airflow grooves 212. In one embodiment, the lower end of the air guide rod 21 is formed with a guide portion 213, which is arc-shaped or semi-circular for easier insertion.

[0031] The following will refer to Figures 1 to 4 The working principle of this utility model will be explained.

[0032] This utility model discloses a quick-connect structure for the air tube of a removable headrest. It involves adding a quick-connect structure for the air tube to the headrest rod and headrest guide sleeve 3. Specifically, the air inlet 1 is located on the headrest guide sleeve 3, and the air guide 2 is located at the lower end of the headrest rod. When the headrest rod with the air guide 2 is not inserted into the headrest guide sleeve 3, the elastic component 13 is not under force, and the air guide valve 11 blocks the air inlet pipe connected to the air inlet nozzle 12, preventing air from being inflated. When the headrest rod with the air guide 2 is fully inserted, the elastic component 13 is compressed, and the air guide valve 11 connects the air inlet pipe to the air outlet nozzle 22 inside the headrest rod, allowing gas to enter smoothly and supply gas to the massage headrest. Furthermore, the air passage is automatically opened and closed during the insertion and removal of the headrest rod. This utility model discloses a quick-connect structure for a pluggable headrest with an air tube. It connects an air pump located in the seat cushion or backrest to a pneumatic module in the headrest, avoiding the negative effects of placing the air pump in the headrest, such as increasing the headrest's volume and increasing noise. This achieves quick connection and noise reduction of the pneumatic massage headrest, providing passengers with a more comfortable massage experience and improving passenger comfort. It also has advantages such as low cost and high safety.

[0033] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
