Technical Field

[0001] The utility model relates to the technical field of silencer devices, in particular to an air inlet and outlet silencer device for an anti-snoring pillow. Background Art

[0002] An anti-snoring pillow is a pillow that can improve snoring during sleep. Its working principle is to set up multiple air bags inside the pillow, and at the same time set up an air pump on the outside of the pillow to inflate the air bags. By controlling the inflation and deflation of the air bags, certain parts of the pillow can be adjusted to rise and fall, thereby prompting the user's head to slowly turn, adjust the sleeping position, relax the respiratory tract, and stop snoring.

[0003] However, during the process of inflating or deflation of the airbag, the airflow flows rapidly in the pipe, causing the pipe to vibrate at high frequency and emit noise, especially at the part of the pipe close to the air pump and the exhaust pipe outlet. In addition, the air pump also generates noise when working. The superimposed noise has a high decibel level, which can affect the user's sleep and even wake the user up, causing the user's physical sensation to decrease. Utility Model Content

[0004] The main purpose of the utility model is to provide an anti-snoring pillow air inlet and outlet silencer, aiming to reduce the noise emitted by the pipeline and the air pump of the anti-snoring pillow when working, so as to improve the sleep quality of the user.

[0007] A silencer mechanism is arranged in the installation cavity, and includes two first silencers and a second silencer. The two first silencers are respectively connected to the air inlet pipe and the air outlet pipe to absorb the vibration generated by the air flow in the pipe. The second silencer is attached to the inner wall of the installation cavity and partially covers the air pump and the first silencer.

[0008] In one embodiment of the present invention, the first sound-absorbing member comprises:

[0009] A cylinder portion, wherein the cylinder portion has a muffler cavity inside, the muffler cavity has an open end, and a first through hole is formed on a side of the muffler cavity away from the open end;

[0010] A sealing cover is covered on the open end, a second through hole is provided on the surface of the sealing cover, or a plurality of air outlet holes are provided on the surface of the sealing cover.

[0011] In an embodiment of the present invention, the muffler cavity is filled with sound-absorbing cotton.

[0012] In an embodiment of the present invention, the edge of the sealing cover is bent to form a limiting ring, and the limiting ring fits and covers the outer wall surface of the open end.

[0013] In one embodiment of the utility model, the shell is composed of an upper cover part and a lower cover part, and the second muffler includes an upper edge part and a lower edge part, and the upper edge part and the lower edge part are respectively arranged on the inner wall surfaces of the upper cover part and the lower cover part.

[0014] In an embodiment of the present invention, the second sound-absorbing member is made of foam plastic.

[0015] The technical solution of the utility model is to arrange a first silencer connected to the air inlet pipe and the air outlet pipe in the shell.

[0024] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] Reference Figures 1 to 4 The utility model proposes an air inlet and outlet silencer device for an anti-snoring pillow, comprising a shell 1 and a silencer mechanism 3. The shell 1 has an installation cavity 2 inside, an air inlet pipe 21 and an air outlet pipe 22 are arranged in the installation cavity 2, an air inlet pipe 21 is connected to an air pump 23 at its mouth, and the air pump 23 is electrically connected to a circuit board 24; the silencer mechanism 3 is arranged in the installation cavity 2, comprising two first silencers 4 and a second silencer 7, the two first silencers 4 are respectively connected to the air inlet pipe 21 and the air outlet pipe 22 to absorb the vibration generated by the air flow in the pipe, and the second silencer 7 is attached to the inner wall of the installation cavity 2 and partially covers the air pump 23 and the first silencer 4.

[0026] It can be understood that the air inlet pipe 21 and the air outlet pipe 22 are respectively connected to the airbags in the anti-snoring pillow outside the shell 1, and are used to inflate or exhaust the airbags. The air pump 23 is connected to the air inlet pipe 21 to pump air into the pipe. The circuit board 24 is connected to the air pump 23 to control the opening or closing of the air pump 23.

[0027] The first muffler 4 is filled with elastic shock-absorbing materials, such as foam plastics, polyester fiber, rubber, sound-absorbing cotton 54, etc. One first muffler 4 is connected to the position of the air inlet pipe 21 close to the air pump 23, and the other is connected to the pipe mouth of the air outlet pipe 22. These two positions are the positions where the noise is the largest when the airflow flows through the pipeline. The shock-absorbing material inside the first muffler 4 can effectively absorb the vibration generated by the pipeline to achieve the purpose of noise reduction; because the air pump 23 will also generate a large noise during operation, the present embodiment also provides a second muffler 7 to cover the air pump 23, which can absorb the noise generated by the air pump 23. At the same time, the second muffler 7 also covers the air inlet pipe 21, the air outlet pipe 22 and a part of the first muffler 4, further reducing the noise generated by the airflow flowing in the pipeline, and the second muffler 7 can also play a certain buffering and protective role for the components it covers.

[0028] Under the joint action of the first muffler 4 and the second muffler 7, the noise generated by the entire device during operation can be greatly reduced, thereby avoiding affecting the user's sleep and greatly improving the user's physical sensation.

[0029] Reference Figures 3 to 4 In one embodiment of the present application, the first silencer 4 includes a cylindrical body 5 and a sealing cover 6, the cylindrical body 5 has a silencer cavity 51 inside, the silencer cavity 51 has an open end 52, and a first through hole 53 is provided on a side of the silencer cavity 51 away from the open end 52; the sealing cover 6 covers the open end 52, and a second through hole 61 is provided on the surface of the sealing cover 6, or a plurality of air outlet holes 62 are provided on the surface of the sealing cover 6.

[0030] It can be understood that the barrel portion 5 and the sealing cover 6 are separately arranged, and the two are connected together to form the first silencer 4. The silencer cavity 51 inside the barrel portion 5 is used to fill with elastic shock-absorbing material, and a first through hole 53 is opened at the bottom end of the silencer cavity 51, which is used to allow the air inlet pipe 21 or the air outlet pipe 22 to be inserted into the silencer cavity 51 through the first through hole 53. At the same time, since the air inlet pipe 21 needs to pass through the first silencer 4 to be connected to the air pump 23, a second through hole 61 is opened on the corresponding sealing cover 6 to facilitate the passage of the air inlet pipe 21; the air outlet pipe 22 does not need to pass through the first silencer 4, but the air flow flowing out of the air outlet pipe 22 needs to be discharged from the first silencer 4, so a plurality of air outlet holes 62 are opened on the sealing cover 6 of the corresponding first silencer 4.

[0031] The elastic shock-absorbing material in the silencer chamber 51 completely covers the air inlet pipe 21 and the air outlet pipe 22 extending into the silencer chamber 51, and the two first silencers are located at the parts with the loudest noise in the pipeline, which can effectively absorb the vibration generated by the pipeline and have a better noise reduction effect; the cylinder body 5 and the cover body are separately arranged, so that the sealing cover 6 can be easily opened to check the condition inside the silencer chamber 51.

[0032] Reference Figures 3 to 4 In one embodiment of the present application, the muffler cavity 51 is filled with sound-absorbing cotton 54 .

[0033] It can be understood that the use of sound-absorbing cotton 54 as the shock-absorbing material inside the first silencer 4 has the following advantages: excellent sound absorption effect, the sound-absorbing cotton 54 usually has a high sound absorption performance, can effectively absorb sound waves, reduce noise levels and echo effects; light weight, the sound-absorbing cotton 54 is usually relatively light, and can reduce the overall weight of the device; strong plasticity, the sound-absorbing cotton 54 usually has good plasticity, and can be more conveniently filled into the silencer cavity 51 and cover the air inlet pipe 21 or the air outlet pipe 22; good durability, the sound-absorbing cotton 54 has a long service life, and can play a long-term and stable sound-absorbing role; safe and environmentally friendly, most of the sound-absorbing cotton 54 is made of environmentally friendly materials, does not contain harmful substances, and is friendly to human health and the environment.

[0034] Reference Figure 4 In one embodiment of the present application, the edge of the sealing cover 6 is bent to form a limiting ring 63 , and the limiting ring 63 fits and covers the outer wall surface of the open end 52 .

[0035] It can be understood that the inner diameter of the limiting ring 63 is the same as the outer diameter of the barrel portion 5, and can wrap the edge of the barrel portion 5 when the sealing cover 6 is connected to the barrel portion 5. On the one hand, it can increase the sealing performance of the muffler chamber 51. On the other hand, the friction force generated by the limiting ring 63 and the surface of the barrel portion 5 makes it difficult for the barrel portion 5 to be separated from the sealing cover 6, and the connection between the two is relatively stable. When it is necessary to separate the sealing cover 6 and the barrel portion 5, it is only necessary to pull the barrel portion 5 out of the limiting ring 63 with force, which is more convenient.

[0036] Reference Figure 2 In one embodiment of the present application, the shell 1 is composed of an upper cover portion 11 and a lower cover portion 12, and the second muffler 7 includes an upper edge portion 71 and a lower edge portion 72, and the upper edge portion 71 and the lower edge portion 72 are respectively arranged on the inner wall surfaces of the upper cover portion 11 and the lower cover portion 12.

[0037] It can be understood that the shell 1 is composed of two parts, namely the upper cover part 11 and the lower cover part 12. Compared with a single one-piece molding structure, it has higher structural strength and stronger load capacity, which makes the service life of the shell 1 longer; and the shell 1 can be easily opened to inspect the components inside the installation cavity 2.

[0038] Optionally, the upper cover portion 11 and the lower cover portion 12 can be connected together by means of threaded connection, snap connection, interference fit, etc. In this example, threaded connection is preferred, so that the connection between the upper cover portion 11 and the lower cover portion 12 is firm and not easy to loosen.

[0039] The second silencer 7 is also divided into an upper edge piece 71 and a lower edge piece 72, which are respectively attached to the inner walls of the upper cover portion 11 and the lower cover portion 12. When the upper cover portion 11 and the lower cover portion 12 are closed together, the upper edge piece 71 and the lower edge piece 72 are also completely attached to cover the air pump 23 and other components. The above arrangement can expose the air pump 23, the first silencer 4 and other components when the shell 1 is opened, so as to facilitate their inspection. At the same time, when the shell 1 is closed, the components can be better covered.

[0040] Reference Figures 2 to 3 In one embodiment of the present application, the second sound-absorbing member 7 is made of foam plastic.

[0041] It can be understood that the use of foam plastic to make the second sound-absorbing component 7 has the following advantages: light and soft, foam plastic is usually very light and soft, and can effectively reduce the overall weight of the device; good sound absorption effect, although foam plastic is light, its porous structure gives it good sound absorption performance, which can effectively absorb sound waves and reduce noise levels; strong durability, foam plastic usually has a long service life, corrosion resistance, and is not easily affected by humidity or moisture, so it can play a long-term and stable sound absorption role; easy to process, foam plastic has good plasticity, and can be easily cut, folded or bent to facilitate adaptation to the internal shape of the installation cavity 2; economical and affordable, foam plastic is usually relatively low in price, and is an economical and affordable sound-absorbing material choice.

[0042] The technical solution of the utility model is to arrange a first silencer 4 connected to the air inlet pipe 21 and the air outlet pipe 22 in the shell 1. The first silencer 4 is filled with sound-absorbing cotton 54, which can effectively absorb the noise generated when the air flows in the pipeline. At the same time, a second silencer 7 covering the air pump 23 and the first silencer 4 is also arranged in the shell 1. It can absorb the noise when the air pump 23 is running and further reduce the noise generated by the pipeline, so that the noise generated by the whole device during operation is greatly reduced, which greatly improves the sleep quality of the user.
