Description

Technical Field

[0001] The utility model relates to the technical field of head adjustment, in particular to a head position adjustment device and a pillow. Background Art

[0002] An estimated 936 million adults aged 30-69 worldwide have mild to severe obstructive sleep apnea, and 425 million adults aged 30-69 have moderate to severe obstructive sleep apnea. The largest number of people are affected in China, followed by the United States, Brazil and India.

[0003] About 350 million people in China snore when they sleep. 30% of people over 30 years old snore, and 40% of people over 40 years old snore. As people age, more and more people will join the snoring team. After 65 years old, half of the people snore and cannot sleep.

[0004] The incidence of snoring in children is about 1%-3%. The male-to-female ratio among snoring people is 2:1, and 2 / 3 of people complain that their spouses snore.

[0005] Snoring is divided into primary snoring and obstructive sleep apnea syndrome. It should be noted that more than 1 / 4 of people who simply snore habitually all year round suffer from obstructive sleep apnea syndrome, and 80% of them do not know it themselves.

[0006] Obstructive Sleep Apnea syndrome (OSA) is characterized by repeated upper airway collapse during sleep, leading to obstructive apnea and hypopnea. The prevalence of OSA in people over 65 years old is as high as 20% to 40%. Every day, 3,000 people die from OSA worldwide. The prevalence of OSA in my country is 3% to 4% of the total population, and 56% to 75% of OSA patients can be improved through postural therapy.

[0007] We estimate that globally, 936 million adults (men and women) aged 30-69 years have mild to severe obstructive sleep apnea, and 425 million adults aged 30-69 years have moderate to severe obstructive sleep apnea. The largest number of people are affected in China, followed by the United States, Brazil, and India.

[0008] There are many reasons for snoring, including abnormalities in the anatomical structure of the nasal cavity, pharyngeal cavity, and laryngeal cavity, such as nasal polyps, deviated nasal septum, enlarged adenoids or tonsils, as well as lifestyle habits such as smoking, drinking, and drug use, and systemic diseases such as acromegaly and hypothyroidism. Snoring not only affects sleep quality, but long-term existence may also cause a variety of diseases in the cardiovascular, endocrine, respiratory, urinary, and digestive systems, such as Figure 6As shown, the most important thing is the obstruction of the airway in sleep apnea, which causes the airway to collapse and be blocked, and air cannot flow. When OSA patients lie in the supine position, the soft tissues of the upper airway, such as the tongue and soft palate, fall back due to the effect of gravity, resulting in upper airway obstruction; while in the lateral position, the effect of gravity is weakened, and the degree of fall of the upper airway soft tissue is reduced.

[0009] Treatments for snoring include medication, surgery, cryogenic minimally invasive ablation, and monitoring and treatment using medical devices. In addition, improving lifestyle habits, such as increasing physical exercise, quitting smoking and drinking, controlling weight, avoiding certain medications, and sleeping in a side-lying position, can also help relieve snoring symptoms.

[0010] In the prior art, a snoring prevention pillow is often used to adjust the height of the pillow during sleep to change the shape of the airway of the human body, thereby alleviating the occurrence of snoring.

[0011] For example, an anti-snoring pillow with application number CN201621494435.7 and its application on the same day with application number CN201611266448.3, the technical points of which are: it includes a hard pad located at the bottom layer, a mounting plate located at the middle layer, and an elastic panel located at the surface layer, an elastic air bag is fixed in the middle of the surface of the mounting plate, and a first receiving groove for accommodating the elastic air bag is provided in the middle of the bottom surface of the elastic panel, and the elastic air bag is supplied with air through an external air pump; a control circuit board is also provided on the mounting plate, and a sound sensor for detecting the characteristic frequency of snoring, a central processing unit for processing the signal collected by the sound sensor and controlling the opening and closing of the air pump is provided on the control circuit board; a neck support strip with a harderness greater than that of the elastic panel is fixed to the front side of the middle of the surface of the mounting plate, and a second receiving groove for accommodating the neck support strip is provided on the front side wall of the middle of the bottom surface of the elastic panel; the front and rear side walls of the elastic air bag are respectively provided with V-shaped grooves are arranged in sequence along the axial direction of the elastic airbag, and the V-shaped grooves on the elastic airbag correspond to the V-shaped convex strips on the front and rear side walls of the first accommodating groove; an air jet hole is provided on one side of the upper surface of the elastic panel, and a medicine storage cavity for storing anti-snoring drugs is provided inside the elastic panel, and the air jet hole is connected to the medicine storage cavity; three types of air pipes are distributed on the mounting plate, namely, an airbag connecting pipe, an air pump connecting pipe and a medicine storage cavity connecting pipe, and the three types of air pipes are respectively connected to a three-way control valve, and the three-way control valve includes a valve seat, a valve core, and a control motor, the valve seat is fixed on the mounting plate, the valve core is circular and rotatably connected to the center of the valve seat, the control motor is located below the valve core and drives the valve core, and the control motor is controlled by the central processing unit; a ventilation duct is provided inside the valve core, and the valve core is driven to rotate by the motor to realize that the ventilation duct connects the airbag connecting pipe with the air pump connecting pipe, or the airbag connecting pipe with the medicine storage cavity connecting pipe.

[0012] In the above solution, when the patient snores, the sound sensor collects the signal, the central processor turns off the air pump supply, and removes the air inside the elastic airbag, causing the middle of the elastic panel to lose support and concave, and the patient's headrest sinks. At the same time, the neck support bar lifts the patient's neck, so that the patient's entire head slowly tilts back, keeping the pharynx and upper airway unobstructed, effectively reducing snoring. When the patient stops snoring, the sound sensor senses that the ambient decibel has dropped, and the central processor controls the air pump supply to inflate the airbag again, allowing the patient to have a better head sleeping posture.

[0013] The comparative document reduces snoring by letting the patient's head tilt back. However, when lying on your back, gravity will pull the tongue and soft palate downward, causing them to collapse into the back of the throat, leading to snoring. Although simply adjusting whether the head tilts back can achieve a certain degree of anti-snoring effect, due to certain limitations in the types of changes, it can only be repeatedly adjusted to tilt the head back to reduce snoring. But for stopping snoring, the supine sleeping posture still keeps the tongue root falling back, and this problem is one of the main causes of airway occlusion and snoring. Therefore, in medical treatment, doctors often recommend that patients sleep on their side to avoid the tongue root falling back and causing airway occlusion and snoring, but the prior art cannot do this. The existing technology still uses the supine sleeping posture to adjust the degree of head tilt back to open the airway and reduce snoring, and cannot improve the situation of airway occlusion caused by the tongue root falling back and causing snoring.

[0014] Therefore, a head position adjustment device and a pillow are proposed to solve or alleviate the above problems. Utility Model Content

DETAILED DESCRIPTION

[0055] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0056] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0058] In the description of the present utility model, it should be understood that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is conventionally placed when in use, or are the orientations or positional relationships conventionally understood by those skilled in the art. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present utility model.

[0059] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0060] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] A head position adjustment device, such as Figure 1 , Figure 3 and Figure 4As shown, it includes a base pad 101, a pressure sensor 102 fixedly connected to the base pad 101, five large three-layer air bags 2 evenly spaced thereon, and an air control structure arranged on the base pad 101;

[0062] The air control structure is connected to the three-layer air bag;

[0063] The pressure sensor 102 is coupled to a controller circuit board 408 in the air control structure, and the controller circuit board 408 is also coupled to a sound sensor;

[0064] The controller circuit board 408 controls the air control structure to adjust the five large three-layer airbags 2 to switch between four states according to the sound sensor and the pressure sensor 102. The controller circuit board 408 controls the air control structure to adjust the air volume in the five large three-layer airbags 2 according to the air pressure feedback in the large three-layer airbags 2.

[0065] The bottom pad 101 plays the role of the above structure, so that when the large three-layer airbag 2 is deformed, it can expand with the bottom pad 101 as the force point. At the same time, when the user's head rests on the large three-layer airbag 2, the large three-layer airbag 2 can be used as an intermediary for force transmission, so that the pressure sensor 102 can feedback the position of the user's head.

[0066] The sound sensor receives the snoring sound from the user and generates a sound signal to be transmitted to the controller circuit board 408, so that the controller circuit board 408 can adjust the inflation and deflation degree of the large three-layer airbag 2 after receiving the signal.

[0067] The controller circuit board 408 receives the pressure signal from the pressure sensor 102 in order to store information and facilitate the subsequent adjustment of the position of the user's head. After receiving the sound signal, it controls the specific large three-layer airbag 2 to inflate and deflate according to the user's head position, so that the five large three-layer airbags 2 can be adjusted between the four states of the composition, and then the user's head can be moved so that the user's head can remain on the left side, right side and normal pillow state. When the five large three-layer airbags 2 are in a fully inflated state or a fully flat state, the user's head can remain in a normal pillow state. When the shape and specifications of the five large three-layer airbags 2 change, the five large three-layer airbags 2 can also be changed from a fully inflated state to a fully flat state, and the head can be tilted back. In addition, when the user's head is kept on the left or right side, since the root of the tongue in the user's head will not fall back, the airway is no longer blocked, and the user's snoring symptoms can be alleviated to a certain extent when the airbags are unobstructed.

[0068] The air control structure can complete the inflation and deflation work according to the control of the controller circuit board 408, and can complete the inflation and deflation actions of the five large three-layer airbags 2, so that the five large three-layer airbags 2 can switch between four states, contributing to the adjustment of the user's head position.

[0069] Alternatively, if Figure 1 and Figure 4 As shown, the air control structure includes an air pump 402 and a controller circuit board 408;

[0070] The controller circuit board 408 includes a circuit board, an air pressure sensor and an MCU arranged thereon. The input end of the MCU is coupled to the air pressure sensor, the pressure sensor 102 and the sound sensor respectively, and the output end of the MCU is coupled to the air pump 402 .

[0071] The air pump 402 inflates or deflates air under the control of the MCU in the controller circuit, thereby adjusting the thickness and hardness of the large three-layer airbag 2. During this period, the operation of the air pump 402 is affected by the feedback from the pressure sensor 102, the sound sensor and the air pressure sensor, and can automatically complete the inflation and deflation of the large three-layer airbag 2.

[0072] It should be noted that the action of controlling the air pump 402, solenoid valve 1 406 and solenoid valve 2 407 through the MCU according to the pressure sensor 102, the air pressure sensor and the sound sensor does not involve any improvement in the program, but is only a conventional application of the MCU and the pressure sensor 102, the air pressure sensor and the sound sensor, so it will not be elaborated here.

[0073] Optionally, the five large three-layer airbags 2 include airbag one, airbag two, airbag three, airbag four and airbag five;

[0074] The four states of the five large three-layer airbags 2 include a fully inflated state, a fully flattened state, a two-inflated and three-flattened state, and a three-inflated and two-flattened state;

[0075] The full drum state includes five large three-layer air bags 2 all inflated;

[0076] The fully flat state includes five large three-layer airbags 2 all deflated;

[0077] The two-inflated and three-flattened state includes airbags 2 and 4 being inflated, and airbags 1, 3 and 5 being deflated;

[0078] The three-inflated-two-flat state includes airbag two and airbag four being deflated, and airbag one, airbag three, and airbag five being inflated.

[0079] When the five large three-layer airbags 2 are in a fully inflated state, the large three-layer airbags 2 can lift the user's head so that the user's cervical spine can maintain a relatively comfortable angle. When the user begins to snore during sleep, it is only necessary to make the shape of the five large three-layer airbags 2 present a non-uniform structure, that is, to adjust them to a fully flat state, so that the user's head is downward and the head is tilted back. When the head is tilted back, the tongue and the lower jaw move forward relative to each other, which helps to open the airway and reduce obstruction, and the tilting of the head can reduce the vibration of the soft palate and uvula because they do not compress the airway as much as when the head is tilted forward. Secondly, the tilting of the head may move the tongue further away from the posterior pharyngeal wall, thereby reducing airway obstruction caused by the tongue falling back, and the tilting of the head helps people to more easily adopt a side-lying position so that the user's head can be subsequently shifted to the left or right side.

[0080] Alternatively, if Figure 2 and Figure 4 As shown, the gas control structure also includes a solenoid valve 1 406 and a solenoid valve 2 407 coupled to the MCU, and both the solenoid valve 1 406 and the solenoid valve 2 407 are two-position three-way solenoid valves;

[0081] The first opening of solenoid valve 406 is connected to the air pump 402, the second opening of solenoid valve 406 is connected to the first opening of solenoid valve 2 407, the third opening of solenoid valve 406 is open, the third opening of solenoid valve 2 407 is connected to air inlet and outlet pipe 1 4062, the second opening of solenoid valve 2 407 is connected to air inlet and outlet pipe 2 4071, air inlet and outlet pipe 2 4071 is connected to airbag 1, airbag 3 and airbag 5, air inlet and outlet pipe 1 4062 is connected to airbag 2 and airbag 4, and the connection point between solenoid valve 1 406 and air inlet and outlet pipe 1 4062 is connected to an air pressure pipe 4061 fixedly connected to the detection end of the air pressure sensor.

[0082] When the air pump 402 is working, different pipelines are switched through the solenoid valve 1 406 and the solenoid valve 2 407 to realize air circulation, and inflation and exhaust are realized by keeping only the solenoid valve 1 406 unobstructed, or keeping both the solenoid valve 1 406 and the solenoid valve 2 407 unobstructed, or blocking both the solenoid valve 1 406 and the solenoid valve 2 407, thereby switching the five large three-layer airbags 2 between four states.

[0083] Alternatively, if Figure 4 As shown, the air control structure also includes a first-stage deceleration and noise reduction component and a second-stage deceleration and noise reduction component;

[0084] The first-stage deceleration and noise reduction component is connected to the air pump 402 through the connecting air pipe 4031;

[0085] The first-stage deceleration and noise reduction component and the second-stage deceleration and noise reduction component are connected via the connecting air pipe 2 4032;

[0086] The secondary deceleration and noise reduction assembly is connected to the solenoid valve 1 406 via the connecting air pipe 3 405;

[0087] Solenoid valve 1 406 and solenoid valve 2 407 are connected via connecting air pipe 4 4063 .

[0088] The first-stage deceleration and noise reduction component decelerates the fast-flowing air from the air pump 402 to the solenoid valve 406, so that after the air flow rate is slowed down, the noise generated during its flow can be reduced. In this way, the air guided by the air pump 402 can achieve the first deceleration and also perform the first noise reduction work.

[0089] The secondary deceleration and noise reduction component performs a secondary deceleration on the airflow after deceleration and noise reduction by the primary deceleration and noise reduction component, thereby forming a turbulent flow therein, thereby reducing its flow rate, thereby achieving a further noise reduction effect.

[0090] Alternatively, if Figure 4 As shown, the first-stage deceleration and noise reduction component includes an air shell 403, connecting pipes arranged on the two end surfaces of the air shell 403 and connected to each other, and an elastic block filled in the air shell 403. The elastic block is a porous structure with elastic deformation properties. The connecting pipe on one side is connected to connecting air pipe 1 4031, and the connecting pipe on the other side is connected to connecting air pipe 2 4032.

[0091] Under the guidance of the air pump 402, the rapidly circulating air enters the air housing 403 through the connecting air pipe 4031 and the connecting pipe. Since the cross-sectional area of ​​the connecting pipe and the connecting air pipe 4031 is smaller than the cross-sectional area of ​​the air housing 403, the air will experience a first deceleration when entering the air housing, and then a second deceleration when the air impacts the elastic block, and finally the third deceleration is completed in the process of passing through the elastic block with difficulty. In addition, during the deceleration process, the sound waves caused by the air flow are transmitted to the elastic block, and the elastic block undergoes elastic deformation to eliminate its potential energy, thereby making the sound smaller.

[0092] Optionally, the soft block may be one or more of a sponge block, cotton wool, and polyurethane foam.

[0093] The above-mentioned material is only one of the cases provided at present. As long as the elastic block has a porous structure and elastic deformation performance, other materials can also be used as elastic blocks for installation in the air shell 403.

[0094] Alternatively, if Figure 4As shown, the secondary deceleration and noise reduction component includes a small three-layer airbag 404, and a pipe joint 1 4041 and a pipe joint 2 4042 fixedly connected to the small three-layer airbag 404 and connected thereto. The pipe joint 1 4041 is connected to the connecting air pipe 2 4032, and the pipe joint 2 4042 is connected to the connecting air pipe 3 405.

[0095] When the air passing through the first-stage deceleration and noise reduction component enters the small three-layer airbag 404 through the connecting air pipe 2 4032, the air will first blow up the small three-layer airbag 404, so that the air will appropriately discharge some air in the process of blowing up the small three-layer airbag 404 and leave through the connecting air pipe 3 405. In addition, the air in the small three-layer airbag 404 will disturb the subsequent incoming air, and then reduce its flow rate, so that the sound that can be made by the air with reduced flow rate is naturally further reduced.

[0096] Alternatively, if Figure 1 , Figure 3 and Figure 4 As shown, the large three-layer airbag 2 and the small three-layer airbag 404 both include three airbags that are interconnected, and the cross-sectional area of ​​the connecting portion of the three airbags is less than half of the cross-sectional area of ​​the airbags.

[0097] Since the cross-sectional area of ​​the connecting part of the three airbags is smaller than one half of the cross-sectional area of ​​the airbags, the air makes the large three-layer airbag 2 and the small three-layer airbag 404 inflate slowly rather than inflate them all at once during the process of inflating the large three-layer airbag 2 rather than inflating them all at once. This allows the small three-layer airbag 404 to limit the air flow rate for noise reduction, while the large three-layer airbag 2 can limit the air from entering slowly, preventing the large three-layer airbag 2 from inflating too quickly, causing the user's head to be suddenly lifted up and causing damage to the cervical spine.

[0098] Alternatively, if Figure 2 and Figure 4 As shown, the air control structure also includes a cylindrical shell 301 with an opening at least at one end, a mounting base 401 detachably connected thereto, an end cover 302 that closes the opening of the shell 301, and an air pump 402 suspension structure. The air pump 402 is suspended in the mounting base 401 through the air pump 402 suspension structure, and the first-stage deceleration and noise reduction component, the second-stage deceleration and noise reduction component, the controller circuit board 408, the solenoid valve 1 406 and the solenoid valve 2 407 are also arranged in the mounting base 401.

[0099] The air pump 402 suspension structure supports the air pump 402 and allows it to be suspended on the mounting base 401, thereby preventing the vibration generated during the operation of the air pump 402 from being transmitted outward, and also preventing the sound generated during the operation of the air pump 402 from spreading outward through solid transmission, effectively reducing the possibility of the air pump 402 making noise in the mounting base 401.

[0100] The mounting seat 401 has a bearing effect on many structures in the air control structure, so that these structures can be arranged in the mounting seat 401 and maintain a certain regular state. In addition, the mounting seat 401 and the many structures therein are protected by the outer shell 301 and the end cover 302. When disassembly and maintenance are required, it is only necessary to open the end cover 302 and take the mounting seat 401 out of the outer shell 301, thereby maintaining long-term protection while facilitating maintenance and disassembly.

[0101] Optionally, the housing 301 is a tubular structure, one end of which is provided with a wire groove 3011 and an embedding groove 3012 communicating with the interior, which may be specifically as follows: Figure 1 , Figure 2 and Figure 5 The tubular shape shown;

[0102] The cross section of the mounting seat 401 is in an arc shape, and the inner ring of the mounting seat 401 is fixedly connected with an air pump baffle 4012, and a pipe groove 1 40121 is provided on the air pump baffle 4012. The inner ring of the mounting seat 401 is integrally formed with two shell baffles 4013, an air bag baffle 4014, a plurality of side baffles 1 4015 and side baffles 2 4016, a mounting frame 4017 and an end baffle 4018 in sequence along its length direction, and the outer ring of the mounting seat 401 is integrally formed with an embedded block 4019 embedded in the embedded groove 3012;

[0103] A receiving groove 1 is formed between the two shell baffles 4013, and the gas shell 403 is embedded in the receiving groove 1;

[0104] A second receiving groove is formed between the shell baffle 4013 and the airbag baffle 4014, and the small three-layer airbag 404 is embedded in the second receiving groove;

[0105] A slot is formed between the side baffle plate 1 4015 and the side baffle plate 2 4016, and the controller circuit board 408 is embedded in the slot;

[0106] Solenoid valve 1 406 and solenoid valve 2 407 are embedded in the installation frame 4017;

[0107] A pipe groove 1 40121 is formed on the shell baffle 4013 , a pipe groove 2 40181 is formed on the end baffle 4018 , a connecting air pipe 1 4031 passes through the pipe groove 1 40121 , and an inlet / outlet air pipe 1 4062 and an inlet / outlet air pipe 2 4071 pass through the pipe groove 2 40181 .

[0108] The above content provides an installation and setting method for the air shell 403, the small three-layer airbag 404, the controller circuit board 408, the solenoid valve 1 406, and the solenoid valve 2 407, so that when these structures are stably installed in the mounting seat 401, it is also convenient for the entire air control structure to be assembled. It is only necessary to place each structure into it according to the formed accommodating groove 1, accommodating groove 2, card groove, installation frame 4017, pipe groove 1 40121 and pipe groove 2 40181, thereby reducing the difficulty of installation and assembly and improving production efficiency.

[0109] Alternatively, if Figure 5 As shown, the air pump 402 suspension structure includes a support frame 4022, an elastic connector 4023, a support arc plate 4011 and a buffer ring 4021;

[0110] The support frame 4022 is wrapped around the outside of the air pump 402 to support the air pump 402;

[0111] The support arc plate 4011 is fixedly connected to one end of the mounting seat 401, and the support arc plate 4011 and the mounting seat 401 form a structure with an arc-shaped cross section, and the structure surrounds the outer ring of the support frame 4022;

[0112] The elastic connecting member 4023 connects the support frame 4022 to the inner circle of the supporting arc plate 4011 so that the air pump 402 is suspended in the air;

[0113] The buffer ring 4021 is sleeved on the outer ring of the air pump 402 and has elastic deformation performance.

[0114] The support frame 4022 serves as a carrier for supporting the air pump 402, and wraps the outside of the air pump 402 so that it can be connected to the support arc plate 4011 through the elastic connector 4023. In this way, the air pump 402 can be suspended in a structure with an arc-shaped cross-section composed of the support arc plate 4011 and the mounting seat 401. The elastic force of the elastic connector 4023 can provide a shock-absorbing effect for the air pump 402, and also facilitates the air pump 402 to be pulled back to its original position by the elastic connector 4023 when it deviates in the mounting seat 401, so that it has an automatic reset effect.

[0115] The buffer ring 4021 can be tightly attached to the outer ring of the air pump 402. It has elastic deformation performance and a certain thickness. Therefore, it can play a certain buffering effect when it is on the outside of the air pump 402. It can provide buffering when the air pump 402 collides with the inner ring of the supporting arc plate 4011 and the inner ring of the mounting seat 401, thereby reducing the damage that may occur due to the collision between the two.

[0116] Optionally, the elastic connector 4023 includes one or more of a spring, a rubber rope and a rubber band.

[0117] Springs, rubber ropes and rubber bands can all provide a certain elastic force, and their two ends can be fixed between the supporting arc plate 4011 and the supporting frame 4022 in various ways. In the specific implementation process, a suitable material can be selected as the elastic connector 4023 according to the needs. For example, in an environment with relatively high operating temperature, a metal spring can be used as the elastic connector 4023, while in an environment with relatively low operating temperature, a more economical rubber rope or rubber band can be selected as the elastic connector 4023. The present invention does not limit the specific material, as long as it meets the requirements.

[0118] Alternatively, if Figure 5 As shown, there are four arc-shaped support arms on the support frame 4022, and hooks 40221 are fixedly connected to the support arms;

[0119] Both ends of the supporting arc plate 4011 in the length direction are provided with L-shaped hook grooves 40111;

[0120] The hook portion 40221 is connected to the supporting arc plate 4011 at the hook groove 40111 via an elastic connector 4023 , and both ends of the elastic connector 4023 are fixedly connected with connecting rings 40231 embedded in the hook portion 40221 and the hook groove 40111 .

[0121] The air pump 402 is supported by a support frame 4022 parallel to the length direction of the air pump 402 and four support arms that fit the outer circle of the air pump 402 in order to minimize the contact area between the air pump 402 and the external connection structure. In this case, when the air pump 402 vibrates and collides with the support frame 4022 and the support arm during operation, no obvious sound will occur. At the same time, it can also reduce the material usage, save the weight of the entire device, and reduce costs.

[0122] Furthermore, the hook portion 40221, the hook groove 40111 and the connecting rings 40231 at both ends of the elastic connector 4023 only provide a specific method for an elastic connector 4023 to connect the supporting arc plate 4011 and the supporting frame 4022. In actual applications, it is not limited to the above connection method.

[0123] Optionally, the buffer ring 4021 includes one or more of a sponge ring, a rubber ring, and a foam ring.

[0124] Sponge rings, rubber rings, and foam rings have their own applicable scenarios and different advantages. Sponge rings are soft and elastic, and can adapt to various complex joint structures, thereby increasing the sealing and stability of the material. In addition, sponge rings also have good pressure resistance and anti-aging capabilities.

[0125] Rubber rings have excellent weather resistance and chemical resistance, enabling them to maintain stable performance in a variety of environments such as high temperature, low temperature, grease, chemical erosion, etc. Foam rings are generally made of lightweight materials and have good durability and thermal insulation properties.

[0126] In practical applications, any one or more of the above materials can be selected as the buffer ring 4021. The buffer ring 4021 only needs to provide buffering and anti-collision protection for the outer ring of the air pump 402, and there is no limitation on the specific material.

[0127] Based on the same inventive concept, the utility model also provides a pillow, comprising a pillow body and any one of the above-mentioned head position adjustment devices, wherein the head position adjustment device is arranged in the pillow body.

[0128] By adopting the above solution in the embodiment of the utility model, at least the following technical effects can be achieved:

[0129] The utility model can use the head adjustment device to control the opening and closing, on and off of the air pump 402, the solenoid valve 1 406 and the solenoid valve 2 407 according to the snoring sound received by the sound sensor and the pillow pressure fed back under the large three-layer airbag 2, so that the five large three-layer airbags 2 can be switched from four states and the head of the user who sleeps on them can be adjusted by the device, so as to achieve the three states of lying flat, left side and right side, and even after the shapes of the five large three-layer airbags 2 are changed, the head can be tilted back to relieve snoring, especially through the two states of left side and right side, so that the user will not snore due to airway occlusion caused by the tongue root falling back.

[0130] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
