[0038] The present invention provides a low-noise control box for a functional pillow, which is used for the functional pillow and aims to prevent the noise generated by an air supply device in the control box from being transmitted to the pillow body of the functional pillow and causing noise trouble to the user.

[0039] Refer to Figures 1 to 3 In one embodiment of the present invention, the functional pillow includes an adjustable pillow body, an air bag 600 is provided in the adjustable pillow body, and the low noise control box of the functional pillow includes:

[0040] The box body 100 has a working chamber formed therein;

[0041] The air supply device 200 and the air supply and discharge regulating device 300 are both arranged in the working chamber. The air supply device 200 is connected to the airbag 600 through a first air pipe, and the air supply and discharge regulating device 300 is connected to the airbag 600 through a second air pipe. The air supply and discharge regulating device 300 is provided with an exhaust port to discharge the gas in the airbag 600; and

[0042] The silencer assembly includes a first silencer device 410 disposed on a first air pipe connected to the air supply device 200 .

[0043] Specifically, in this embodiment, the low-noise control box of the functional pillow is arranged on the outside of the adjustable pillow body of the functional pillow. This is because the box body 100 of the low-noise control box of the functional pillow can isolate the noise and vibration generated by the air supply device 200 and the air supply and exhaust adjustment device 300 located in the working chamber of the box body 100, thereby preventing these noises or vibrations from being transmitted through the air or directly contacting the adjustable pillow body through sound-emitting objects and affecting the user, thereby ensuring the user's sleep quality. The air supply device 200 supplies air to the airbag 600 through the first air pipe and the second air pipe to increase the volume of the airbag 600; the air supply and deflation adjustment device 300 is connected to the airbag 600 through the second air pipe, and the air supply and deflation adjustment device is provided with an exhaust port to selectively discharge the gas in the airbag 600 when needed to reduce the volume of the airbag 600. The air supply device 200 and the air supply and deflation adjustment device 300 adjust the volume of the airbag 600, thereby adjusting the height of the adjustable pillow body, and then adjusting the height and angle of the user's head. In this way, the functional pillow can be used to prevent the user from snoring when snoring. In addition, when the height of the adjustable pillow body itself changes back and forth at a certain frequency, it can massage the person's head to promote blood circulation in the person's head and benefit the person's health. When the air supply device 200 is working, the airflow it generates will flow into the airbag 600 through the first air pipe and the second air pipe. However, the noise generated when the air supply device 200 is working will also pass through the tube walls of the first air pipe and the second air pipe and be transmitted to the pillow along with the airflow. The present invention can eliminate these noises by providing a first silencer 410 in the first air pipe connected to the air supply device 200, thereby preventing these noises from causing noise distress to the user and affecting their sleep quality.

[0044] Optionally, in this embodiment, the low noise control box of the functional pillow is further provided with a sound recognition device, and the sound recognition device is used to determine whether the user is in a snoring state.

[0045] Without loss of generality, in this embodiment, the silencer assembly of the low-noise control box of the functional pillow also includes a second silencer 420, which is arranged at the exhaust port of the air supply and deflation adjustment device 300, and is used to eliminate the sound generated when the air supply and deflation adjustment device 300 is exhausted. It can be understood that when the volume of the adjustable pillow body of the functional pillow needs to be reduced, the air supply and deflation adjustment device 300 will discharge the gas in the airbag 600 through the exhaust port. When the gas flows in the trachea, it will rub against the wall of the second trachea to generate noise. When the gas itself generates turbulence, it will also generate noise. When the gas passes through the internal cavity of the air supply and deflation adjustment device 300 and the exhaust port, it will also generate noise. The second silencer 420 can eliminate these noises to prevent these noises from causing trouble to the user, thereby ensuring the user's sleep quality.

[0046] Optionally, in this embodiment, the second silencer 420 and the first silencer 410 are both configured as silencers, which include a vent pipe 430 and a silencer cavity 440. A gas channel 431 is provided through the vent pipe 430. Both ends of the gas channel 431 have openings for connection with a trachea, etc. The air flow in the trachea will flow through the gas channel 431, and the tube wall of the vent pipe 430 is provided with a silencer through hole 450. The silencer through hole 450 is used to connect the gas channel 431 with the silencer cavity 441 in the silencer cavity 440. When the gas flows through the gas channel 431 in the vent pipe 430 and passes through the silencer through hole 450, according to the Helmholtz resonance silencer principle, the air in the silencer cavity 441 resonates. When the frequency of the resonance is consistent with the frequency of the noise to be eliminated, the silencer can eliminate the corresponding noise in the air flow flowing through the gas channel 431.

[0047] Further optionally, in this embodiment, the shape of the silencer chamber 441 of the silencer is configured as a cylinder, and the height and diameter of the silencer chamber 441, and the length and diameter of the silencer through hole 450 can be set to different values ​​corresponding to different frequency bands of the sound to be eliminated by the silencer. According to the Helmholtz resonance silencer principle, when the height and diameter of the silencer chamber 441, and the length and diameter of the silencer through hole 450 are set to different values, the silencer can eliminate noise in different frequency bands. Therefore, in this embodiment, the silencer chamber 441 can set the height and diameter of the silencer chamber 441, and the length and diameter of the silencer through hole 450 to correspond to the frequency band of the corresponding noise according to actual needs, so as to achieve the purpose of eliminating the noise to be eliminated.

[0048] Further optionally, in this embodiment, the muffler is provided with at least two muffler cavities 440, which are arranged side by side in sequence, and the muffler cavity 441 in each muffler cavity 440 is connected to the gas channel 431 through the muffler through hole 450, and the height and diameter of the muffler cavity 441 of the muffler cavities 440, and the length and diameter of the connected muffler through hole 450 are respectively set to correspond to the sound of different frequency bands, so as to eliminate the sound of different frequency bands respectively. It can be understood that the muffler is arranged in this way so that it can simultaneously have the function of eliminating noise of multiple different frequency bands, thereby ensuring that the user's sleep is not affected by noise.

[0049] Further optionally, in this embodiment, the first silencer 410 and the second silencer 420 are respectively used to eliminate sounds of different frequency bands. It can be understood that because the noise emitted by the air supply device 200 and the noise carried by the airflow discharged through the exhaust port of the air supply and exhaust adjustment device 300 have different frequency bands, the first silencer 410 and the second silencer 420 can respectively eliminate the noise of the two in a targeted manner to achieve the purpose of effectively eliminating noise, thereby ensuring the user's sleep quality.

[0050] Without loss of generality, in this embodiment, the low noise control box of the functional pillow also includes an intelligent control module, and the air supply device 200, the air supply and exhaust adjustment device 300 and the sound recognition device are all electrically connected to the intelligent control module. The intelligent control module is used to control the working status of the air supply device 200 and the air supply and exhaust adjustment device 300. When the sound recognition device monitors that the user is in a snoring state, it transmits the monitored information to the intelligent control module, and the intelligent control module then responds accordingly based on the information. These responses include controlling the start and stop of the air supply device 200 and the air supply and exhaust adjustment device 300 to adjust the volume of the airbag 600, thereby adjusting the height and angle of the user's head to prevent the user from snoring.

[0051] Optionally, in this embodiment, the outer wall surface of the box body 100 of the low-noise control box of the functional pillow is provided with a smart touch screen, and the smart touch screen is electrically connected to the smart control module, so that the user can input control instructions to the smart control module, including controlling it to enter or stop working, etc. However, the present design is not limited to this, and in other embodiments, the low-noise control box of the functional pillow can also play a role equivalent to the aforementioned smart touch screen by setting control buttons on the outer wall surface of the box body 100.

[0052] Without loss of generality, in this embodiment, the low-noise control box of the functional pillow also includes a shockproof connector, one end of which is connected to the air supply device 200, and the other end is connected to the inner wall of the box body 100, so as to suspend the air supply device 200. It can be understood that the air supply device 200 will generate noise and vibration when working. These noises and vibrations will generally be transmitted along with the objects in contact with the air supply device 200 and affect the user, thereby reducing the user's sleep quality. Solids are good conductive media for sound and vibration, especially vibrations will be transmitted more through solids, and the essence of sound is the vibration of objects. These vibrations will not only cause a sense of vibration to the user's body touch, but also generate certain noise to cause auditory distress to the user. Therefore, the practical shockproof connector will suspend the air supply device 200, thereby reducing the contact area between the air supply device 200 and the box body 100, thereby reducing the amount of these noises and vibrations transmitted to the user, ensuring that the user's sleep quality is not affected.

[0053] Optionally, in this embodiment, the material of the shockproof connector is silicone, which has good elasticity and toughness and can effectively reduce shock. In addition, silicone is cheap and easy to obtain. However, the present design is not limited to this. In other embodiments, the material of the shockproof connector can also be and is not limited to rubber, foam or sponge.

[0054] Without loss of generality, in this embodiment, the air supply and discharge adjustment device 300 is configured as a solenoid valve, the air supply device 200 is connected to the solenoid valve through a first air pipe, and the solenoid valve is connected to the airbag 600 in the adjustable pillow body through a second air pipe, and the solenoid valve is provided with an exhaust port. It can be understood that the solenoid valve has the function of adjusting the connection relationship between the air supply device 200, the airbag 600 and the exhaust port. When the air supply device 200 and the airbag 600 are in a connected state, the air supply device 200 can inflate the airbag 600, and when the airbag 600 and the exhaust port are in a connected state, the gas in the airbag 600 can be discharged through the exhaust port. Optionally, in this embodiment, the air supply device 200 is configured as an air pump.

[0055] The present invention also proposes a functional pillow, which includes the low-noise control box of the functional pillow. The specific structure of the low-noise control box of the functional pillow refers to the above embodiment. Since the functional pillow adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The intelligent functional pillow also includes: an adjustable pillow body, an air bag 600 is arranged in the adjustable pillow body, and the air supply device 200 in the low-noise control box of the functional pillow is connected to the air supply and deflation adjustment device 300 through the first air pipe, and the air supply and deflation adjustment device 300 is connected to the air bag 600 through the second air pipe.

[0056] Optionally, a third muffler 700 is provided in the adjustable pillow body of the functional pillow, and the third muffler 700 is provided at the connection between the second trachea and the airbag, and the third muffler 700 is configured as a muffler, which is used to eliminate the noise brought by the airflow flowing into the airbag 600 through the trachea. It can be understood that the provision of the third muffler 700 can prevent the noise generated by the gas during the flow from being transmitted to the airbag 600 to affect the user's sleep.

[0057] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
