Most traditional air source pumps are rotary air pumps driven by motors or use electromagnetic force vibration to achieve the effect of air compression. This type of air pump will produce audible noise when working. The noise of this air pump used in the anti-snoring pillow will affect the user's sleep.

[0003] The existing patent document (CN202021598116.7) discloses an anti-snoring device, which uses a motor air pump. This air pump will produce noise audible to the human ear when working. Utility Model Content

The high-frequency piezoelectric pump operates at a frequency above 20,000 Hz, and the frequency of noise generated is higher than the hearing range of the human ear, thereby achieving the effect of noise reduction and silencing, and avoiding noise troubles to users.

[0005] In order to solve the above technical problems, the utility model provides a silent anti-snoring pillow with a high-frequency piezoelectric pump, comprising:

[0006] The anti-snoring pillow body is made of soft material;

[0007] The anti-snoring functional component includes a plurality of airbag units arranged in a straight line along the length direction of the anti-snoring pillow body;

[0008] An air supply and exhaust device, the air supply and exhaust device comprises a control circuit board, an air path switching valve group and a high-frequency piezoelectric pump, the control circuit board is respectively connected to the air path switching valve group and the high-frequency piezoelectric pump, and the high-frequency piezoelectric pump is connected to each airbag unit of the anti-snoring function component through the air path switching valve group;

[0009] When the high-frequency piezoelectric pump expands or contracts at least one of the airbag units through the air path switching valve group, the frequency of the noise generated by the operation of the high-frequency piezoelectric pump is higher than 20,000 Hz.

[0010] Furthermore, the anti-snoring pillow body includes a pillow bottom structure and a soft pillow core arranged on the pillow bottom structure.

[0011] Furthermore, the pillow bottom structure is in the shape of a flat plate, and the soft pillow core has a first accommodating groove and a second accommodating groove with openings facing downwards, the first accommodating groove is used to accommodate the anti-snoring functional component, and the second accommodating groove is used to accommodate the air supply and exhaust device.

[0012] Furthermore, the anti-snoring functional component is arranged between the pillow bottom structure and the soft pillow core.

[0013] Furthermore, the air supply and exhaust device also includes an air pump box shell, which is arranged between the pillow bottom structure and the soft pillow core and is located on one side of the anti-snoring functional component.

[0014] Furthermore, the air pump box shell includes an upper shell and a lower shell that are detachable from each other.

[0015] Furthermore, an air path through hole is provided on the side wall of the air pump box shell facing the anti-snoring functional component, and the air path through hole is used to allow the air supply pipeline to pass through, and the air supply pipeline is respectively connected to the air path switching valve group and the anti-snoring functional component.

[0019] As described above, the silent anti-snoring pillow with a high-frequency piezoelectric pump of the utility model has the following beneficial effects: the anti-snoring pillow product is a typical product used in sleeping scenes, and has extremely high requirements for noise control. Under this background condition, the use of a high-frequency piezoelectric pump that is silent within the human hearing frequency range as the air source component of the anti-snoring pillow product can well solve the problem of noise. The high-frequency piezoelectric pump is a new type of air source pump, and its core driving gas core component is made of piezoelectric material. Its vibration frequency is above 20KHz, and the sound emitted is in the ultrasonic band, which cannot be heard by the human ear, achieving the purpose of silence. The silent anti-snoring pillow of the utility model is driven by a high-frequency piezoelectric pump to achieve the effect of silent operation. Although the high-frequency piezoelectric pump of the utility model itself is an existing structure, the utility model applies a high-frequency piezoelectric pump to an anti-snoring pillow product for the first time. The high-frequency piezoelectric pump works by utilizing the piezoelectric effect unique to piezoelectric materials. When an alternating excitation is applied to the piezoelectric ceramic on the piezoelectric vibrator, the piezoelectric effect causes the piezoelectric ceramic to deform internally and manifests as macroscopic vibrations, forcing the volume of the pump chamber to change, thereby causing changes in the pressure in the chamber, thereby achieving fluid transmission. High-frequency piezoelectric pumps have the advantages of small size, silence, and long life. Therefore, the utility model can not only utilize ultrasonic technology to generate ultrasonic frequencies higher than the human hearing range, thereby achieving the effect of noise reduction and silencing, avoiding noise troubles for users, but also build the air supply and exhaust device 3 into the product, optimizing the shortcomings of the traditional external air pump box, optimizing the product placement space, and improving the overall aesthetics of the product.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0042] like Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model provides a silent anti-snoring pillow with a high-frequency piezoelectric pump, comprising:

[0043] The anti-snoring pillow body 1 includes a pillow base structure 11 and a soft pillow core 12 disposed on the pillow base structure 11;

[0044] The anti-snoring functional component 2 is arranged between the pillow bottom structure 11 and the soft pillow core 12, and the anti-snoring functional component 2 includes a plurality of airbag units 21 arranged in a straight line along the length direction of the anti-snoring pillow body 1;

[0045] The air supply and exhaust device 3 includes an air pump box housing 31, which is arranged between the pillow bottom structure 11 and the soft pillow core 12 and is located on one side of the anti-snoring functional component 2. A control circuit board 32, an air path switching valve group 33 and a high-frequency piezoelectric pump 34 are arranged in the inner cavity of the air pump box housing 31. The control circuit board 32 is respectively connected to the air path switching valve group 33 and the high-frequency piezoelectric pump 34 for communication. The high-frequency piezoelectric pump 34 is connected to each air bag unit 21 of the anti-snoring functional component 2 through the air path switching valve group 33.

[0046] When the high-frequency piezoelectric pump 34 expands or contracts at least one of the airbag units 21 through the air path switching valve group 33 , the operating sound frequency emitted by the high-frequency piezoelectric pump 34 is higher than 20,000 Hz.

[0047] In the utility model, the soft pillow core 12 is placed on the anti-snoring functional component, which can increase the softness of the silent anti-snoring pillow and enhance the comfort; the pillow bottom structure 11 is placed at the bottom of the anti-snoring functional component, which can increase the height of the silent anti-snoring pillow and protect the anti-snoring functional component. The anti-snoring functional component is composed of a plurality of airbag units, and the action of the airbag units can change the undulating shape of the pillow surface of the anti-snoring pillow body 1, thereby turning the snorer's head, causing the snorer's relaxed respiratory tissue to collapse in a different direction, relieving respiratory obstruction and achieving the purpose of stopping snoring. The air supply and exhaust device 3 is built into the soft pillow core 12. The air path switching valve group 33 is used to control the airbag unit 21 to shrink and expand, so as to achieve the anti-snoring action of turning the head. The control circuit board 32 is used to control the action of the high-frequency piezoelectric pump 34, the anti-snoring functional component 2, and the air path switching valve group 33.

[0048] The anti-snoring pillow product is a typical product used in sleeping scenes, and has extremely high requirements for noise control. Under this background condition, the use of a high-frequency piezoelectric pump 34 that is silent within the human hearing frequency range as the air source component of the anti-snoring pillow product can solve the noise problem very well. The high-frequency piezoelectric pump 34 is a new type of air source pump. The core component of its core driving gas is made of piezoelectric material. Its vibration frequency is above 20KHz (i.e. 20000Hz). The sound emitted is in the ultrasonic band and cannot be heard by the human ear, achieving the purpose of silence. The utility model silent anti-snoring pillow is driven by a high-frequency piezoelectric pump 34 to achieve the effect of silent operation. Although the high-frequency piezoelectric pump 34 of the utility model itself is an existing structure, the utility model applies the high-frequency piezoelectric pump 34 to the anti-snoring pillow product for the first time. The high-frequency piezoelectric pump 34 works by utilizing the piezoelectric effect unique to piezoelectric materials. When an alternating excitation is applied to the piezoelectric ceramic on the piezoelectric vibrator, the piezoelectric effect causes deformation inside the piezoelectric ceramic and manifests as macroscopic vibration, forcing the volume of the pump cavity to change, thereby causing the pressure in the cavity to change, thereby achieving fluid transmission. The high-frequency piezoelectric pump 34 has the advantages of small size, quietness, and long life.

[0049] Therefore, the utility model can not only utilize high-frequency piezoelectric pump technology to make the noise frequency generated by the silent anti-snoring pillow when it is working higher than the human ear's hearing range, thereby achieving the effect of noise reduction and silencing, and avoiding noise troubles to users, but also build the air supply and exhaust device 3 into the product, optimizing the shortcomings of the traditional external air pump box, optimizing the product's placement space, and improving the overall aesthetics of the product.

[0050] Furthermore, in order to facilitate the placement of the anti-snoring functional component 2 and the air supply and exhaust device 3 inside the anti-snoring pillow body 1, the pillow bottom structure 11 is flat, and the soft pillow core 12 has a first accommodating groove and a second accommodating groove opening downward, the first accommodating groove is used to accommodate the anti-snoring functional component 2, and the second accommodating groove is used to accommodate the air supply and exhaust device 3.

[0051] Furthermore, in order to facilitate the disassembly and assembly of the components of the silent anti-snoring pillow, the air pump box shell 31 includes an upper shell 311 and a lower shell 312 that are detachable from each other.

[0052] Furthermore, in order to facilitate the laying of the air supply pipeline, an air path penetration hole 313 is provided on the side wall of the air pump box shell 31 facing the anti-snoring functional component 2. The air path penetration hole 313 is used to allow the air supply pipeline to be laid, and the air supply pipeline is respectively connected to the air path switching valve group 33 and the anti-snoring functional component 2.

[0053] Furthermore, in order to realize that each airbag unit 21 can be independently expanded and contracted, the air path switching valve group 33 includes a plurality of switching valve units 331 arranged in a straight line, and all the switching valve units 331 are connected to all the airbag units 21 in a one-to-one correspondence.

[0054] Furthermore, in order to facilitate the positioning and installation of the gas circuit switching valve group 33 , the gas circuit switching valve group 33 also includes a long strip-shaped positioning and mounting plate 332 , and all the switching valve units 331 are arranged on the positioning and mounting plate 332 .

[0055] Furthermore, the positioning mounting plate 332 is provided with bayonet holes 332a at both ends along its length direction, and the interior of the air pump box housing 31 is provided with a flexible positioning column, which is snap-fitted with the bayonet holes 332a to reduce the vibration transmitted from the switching valve unit 331 to the air pump box housing 31.

[0056] In summary, the utility model of the silent anti-snoring pillow with a high-frequency piezoelectric pump can not only utilize the high-frequency piezoelectric pump technology to generate ultrasonic frequencies higher than the human hearing range, thereby achieving the effect of noise reduction and silencing, avoiding the noise troubles to users, but also has the air supply and exhaust device built into the product, optimizing the shortcomings of the traditional external air pump box, optimizing the product placement space, and improving the overall aesthetics of the product. Therefore, the utility model effectively overcomes the various shortcomings of the existing technology and has a high industrial utilization value.
