[0004] The above technical objectives of the present invention are mainly solved by the following technical solutions: The technical solution of the first technical subject involved in the present invention is:

This technical solution primarily utilizes multiple noise reduction measures, such as a dual-housing structure that combines vibration and noise reduction, a suspended air pump, and a noise reduction housing provided on the outer cover of the air pump. This significantly reduces the operating vibration and noise of the control box, thereby improving the noise level during pillow use and enhancing the user's sleep and rest quality.

[0006] As a further improvement and supplement to the above-mentioned technical solution, the present invention adopts the following technical measures: the noise reduction housing includes a soundproof shell with at least one open end, a soundproof cover that cooperates with the open end, the air pump is disposed within the inner cavity of the soundproof shell, and a tube hole is provided in the soundproof cover. When the soundproof shell is open at one end, a tube hole is provided at the bottom of the soundproof shell. When one end of the soundproof shell is open, the soundproof shell is cylindrical, with a tube hole provided at the bottom of the soundproof shell and another tube hole provided in the soundproof cover that cooperates with the open end, respectively, for allowing the air inlet and outlet pipe sections of the air pump to pass through the corresponding tube holes, or for allowing the corresponding air pipes of the air path mechanism in the control box to pass through the corresponding tube holes, enter the soundproof shell, and connect with the air inlet and outlet of the air pump.

[0029] This technical solution mainly adopts multiple noise reduction measures such as a double shell 1 structure that combines vibration and noise reduction, a suspended air pump 3, and a noise reduction shell on the outer cover of the air pump 3, which is beneficial to significantly reduce the working vibration and working noise of the control box 18, and thus help to improve the noise during the use of the pillow 17, and help to improve the user's sleep and rest quality.

[0030] Next, the above technical solution is described:

[0031] In actual application, the noise reduction shell includes a sound insulation shell 5 with at least one end open, a sound insulation cover 6 matched with the open end, the air pump 3 is arranged in the inner cavity of the sound insulation shell 5, and a pipe hole 7 is provided on the sound insulation cover 6. When the sound insulation shell 5 is open at one end, a pipe hole 7 is provided at the bottom of the sound insulation shell 5.

[0032] When one end of the soundproof shell 5 is open, the soundproof shell 5 is cylindrical, with a tube hole 7 provided at the bottom of the soundproof shell 5. Another tube hole 7 is provided on the soundproof cover 6 that matches the open end. These holes are used to allow the air inlet and outlet sections of the air pump 3 to pass through the corresponding tube holes 7, or to allow the corresponding air pipes on the air path mechanism within the control box 18 to pass through the corresponding tube holes 7 and enter the soundproof shell 5 to connect with the air inlet and outlet of the air pump 3. When both ends of the soundproof shell 5 are open, soundproof covers 6 are provided at each end of the soundproof shell 5, each of which is provided with a tube hole 7. The purpose of providing the tube holes 7 is the same as described above.

[0033] In actual application, the sound insulation cover 6 is a damping sound insulation cover 6, and the corresponding air pipe on the air path mechanism passes through the corresponding pipe hole 7, and cooperates with the air inlet and air outlet of the air pump 3 respectively, and the wall of the air pipe passing through the pipe hole 7 is interference-sealed with the wall of the pipe hole 7.

[0034] Among them, the setting of the damping sound insulation cover 6 is conducive to further improving the sound insulation and noise reduction effect, and is convenient for forming an interference seal with the corresponding pipe wall.

The guide protrusion is used to guide the elastic suspension member 9 through the corresponding connection hole so that the two protrusions 10 are respectively clamped on the corresponding first connection ear 19 and the second housing 1. The flat plate protrusion and the guide protrusion cooperate to ensure the clamping force of the first connection ear 19. The provision of the guide protrusion facilitates the smooth passage of the guide protrusion through the first connection hole, so that the flat plate protrusion and the guide protrusion cooperate to be located at both ends of the first connection hole.

[0039] In actual application, the air path mechanism is detachably fixed to the top wall of the inner shell in a vibration-reducing and noise-reducing manner. That is, the air path mechanism is suspended on the top wall of the inner shell, and the suspension absorbs the vibration generated by the gas flow in the air path mechanism, thereby facilitating the reduction of noise generated by the vibration.

[0040] In actual application, the gas circuit mechanism includes an air inlet buffer box 11 corresponding to the air inlet and air outlet of the air pump 3. The provision of the buffer box 11 is conducive to temporarily buffering the gas entering or exiting the air pump 3, reducing the gas flow rate and the possibility of vortex, thereby reducing the noise generated by the gas flow.

[0041] In actual use, the air circuit mechanism includes a solenoid valve 13 that cooperates with the air pump 3. The solenoid valve 13 is mounted on a noise-reducing and vibration-damping seat 14, which is elastically connected to the inner housing. The noise-reducing and vibration-damping seat 14 is used to absorb vibrations of the solenoid valve 13. The elastic connection between the noise-reducing and vibration-damping seat 14 and the inner housing absorbs the vibrations on the noise-reducing and vibration-damping seat 14, thereby reducing the noise generated by the vibration of the solenoid valve 13.

[0045] Example 2: Figure 8 As shown, the technical solution of the second technical subject of the present invention is: a pillow, including a cover, an air bag arranged in the cover, and connected to the control box 18 through an external air tube.
