Description

Technical Field

[0001] The utility model relates to the technical field of pillows, in particular to an airbag pillow. Background Art

[0002] Due to the fast-paced work and stressful lifestyles, more and more people are experiencing poor sleep quality, lumbar pain, and cervical spondylosis, impacting their physical and mental health and work efficiency. To alleviate these issues, pillows have become a popular solution for many. For example, pillow quality plays a crucial role in ensuring a good night's sleep, and high-quality pillows can effectively alleviate poor sleep quality. People sleep in different postures, such as supine and side sleeping. These different positions create different head and neck heights. Prolonged improper sleeping postures can cause discomfort in the head and neck, impacting sleep quality and even leading to neck problems. According to professional doctors, high-quality pillows should adjust their height in real time based on the person's sleeping position, with a height error of less than 1cm. This eliminates tension in the head and neck, thereby protecting head and neck health. Therefore, it is crucial that pillow height is not only adjustable but also accurately controlled.

[0003] Currently on the market, the most highly adjustable pillows are inflatable airbag pillows. Existing airbag pillows are basically a large airbag in them, which not only supports the neck but also the pillow portion. Although this type of airbag pillow can adjust the pillow's height by inflating and deflating the airbag, the overall height of the pillow increases or decreases after inflation and deflation, making it difficult to provide simultaneous protection for both the head and neck. This often results in the pillow not protecting the neck, or the neck height being appropriate but the head height being inappropriate. Furthermore, the pillow's height cannot be precisely adjusted in different areas, and cannot be tailored to the user's anatomy, making it difficult to achieve high-precision personalized design. This fails to meet doctors' requirements and recommendations for high-quality pillows. Furthermore, the large airbag structure suffers from relatively poor structural stability. When the airbag is locally compressed, the gas within the airbag easily concentrates on the uncompressed side, causing significant deformation. After adjustment, the pillow cannot maintain the adjusted fixed height, negating the purpose of height adjustment. Furthermore, more importantly, when measuring the airbag's height, to ensure measurement accuracy, the height measurement position is generally located in the middle of the airbag. However, a large airbag cannot provide a clearing in the middle for height measurement, and a height measurement device cannot pass through the middle of the large airbag, making height measurement extremely inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide an airbag pillow.

[0005] The technical solution for achieving the purpose of the utility model is: an airbag pillow, including a neck airbag and a head airbag, the neck airbag and the head airbag are horizontally arranged from front to back, the neck airbag corresponds to the position of the human neck, and the head airbag corresponds to the position of the human head; the head airbag includes more than two sub-airbags, and the more than two sub-airbags are horizontally arranged from front to back; a first give way channel is provided between the neck airbag and the adjacent sub-airbags, and a second give way channel is provided between the two adjacent sub-airbags.

[0006] Furthermore, the number of sub-airbags is two. The number of sub-airbags can be two, three, or more. Since pillows are relatively small, the stability of the head airbag formed by two sub-airbags can be greatly improved. When there are two sub-airbags, two adjacent sub-airbags can also be provided with the second height measurement and yield channel to meet height measurement requirements. Compared to other numbers, the configuration of two sub-airbags is simpler.

[0007] Furthermore, the neck airbag is provided with a corresponding first inflatable assembly, and the head airbag is provided with a corresponding second inflatable assembly; the first inflatable assembly and the second inflatable assembly each include an inlet pipe and an outlet pipe, the inlet pipe being equipped with an air pump and a one-way valve, and the outlet pipe being equipped with a deflation valve; in the first inflatable assembly, the inlet pipe and the outlet pipe are both connected to the neck airbag; in the second inflatable assembly, the inlet pipe and the outlet pipe are both connected to the sub-airbags of the head airbag. During operation, when inflating the neck airbag or the head airbag, the corresponding air pump operates, pumping gas into the neck airbag or all the sub-airbags in the head airbag along the inlet pipe; when deflated, the corresponding deflation valve opens, and the gas in the neck airbag or all the sub-airbags in the head airbag is discharged outward along the outlet pipe.

[0008] Furthermore, the inlet and outlet pipes are provided with air chambers, each of which is equipped with sound-absorbing cotton. With these chambers in place, when all the sub-airbags in the neck or head airbags are inflated or deflated, gas passes through the chambers. Due to the expansion of the chambers, the pressure of the gas entering the chambers decreases instantaneously, significantly reducing the noise of air in and out. The sound-absorbing cotton also effectively reduces gas noise by absorbing the air.

[0009] Furthermore, the air pump is covered with a silicone vibration-damping sleeve, which is connected to the fixing frame via a shock-damping spring. Both the silicone vibration-damping sleeve and the shock-damping spring function as shock absorbers, effectively absorbing vibrations during operation of the air pump and thereby reducing noise during inflation and deflation.

[0010] Furthermore, the neck airbag is provided with a corresponding neck airbag height measuring component, and the head airbag is provided with a corresponding head airbag height measuring component; the neck airbag height measuring component and the head airbag height measuring component both include an automatically rotating rotor and a pull rope wound on the rotor;

[0011] In the neck airbag height measuring assembly, the pull rope passes through the first clearance channel, and the free end of the pull rope is pulled above the neck airbag;

[0012] In the head airbag height measurement assembly, the pull rope passes through the second yield channel, and the free end of the pull rope is pulled above the head airbag. The automatically rotating rotor provides a fixed-directional pulling force for the pull rope, so that the pull rope is always taut and straightened. When the taut and straightened pull rope moves up and down with the rise and fall of the neck airbag or the head airbag, the pull rope wound on the rotor is retracted and released, and the rising and falling displacement of the neck airbag or the head airbag is converted into the retracted and released length of the pull rope. Then, according to the retracted and released length of the pull rope on the rotor, the rising and falling displacement of the neck airbag or the head airbag can be measured to obtain the height of the neck airbag or the head airbag. Under the height measurement structure of the rotor and the pull rope, the rising and falling displacement of the neck airbag or the head airbag and the retracted length of the pull rope are in linear proportion, and the final height measurement accuracy is high. Moreover, the drawstring is soft and has strong deformation ability, which is consistent with the high deformation characteristics of the pillow. When the drawstring is used to detect the height of the neck airbag or the head airbag, the drawstring can be integrated with the pillow, which not only facilitates the connection and setting of the drawstring, but more importantly, the setting of the drawstring will not affect the use and comfort of the pillow.

[0013] Furthermore, in the neck airbag height measurement assembly, the pull cord extends vertically through the first clearance channel; in the head airbag height measurement assembly, the pull cord extends vertically through the second clearance channel. The pull cord can be arranged at an angle or vertically. Compared to an angled arrangement, the vertical arrangement allows the retracted and extended length of the pull cord to vary proportionally with the pillow height. The pillow height can be directly calculated from the retracted and extended length of the pull cord, simplifying conversion calculations.

[0014] Furthermore, a layer is stacked on the neck airbag and the head airbag, and the free ends of the two pull cords in the neck airbag height measuring assembly and the head airbag height measuring assembly are both connected to the layer. The free end of the pull cord can be connected to the top of the neck airbag or the head airbag, or to the top of the pillow core or pillowcase. A layer can also be stacked on top of the neck airbag and the head airbag, and the free end of the pull cord is connected to the layer. When the free end of the pull cord is connected to the top of the neck airbag or the head airbag, or the top of the pillow core or pillowcase, the structure of the neck airbag and the head airbag or the pillow pillowcase cannot be destroyed, resulting in relatively great difficulty in connecting the pull cord, and the connection is limited. It can often only be connected by gluing, and the connection firmness and stability are poor. After the layer is stacked above the neck airbag and the head airbag, a hole can be opened on the layer, and the drawstring can be passed through the layer and tied to the layer, or the drawstring and the layer can be sewn together with needle and thread. The connection setting of the drawstring is simpler, and the connection is more firm and reliable.

[0015] Furthermore, the airbag pillow includes a pillow core, wherein the neck airbag and the head airbag are both installed in the pillow core. The arrangement of the pillow core can be used as a packaging and can also improve the comfort of the pillow.

[0016] Furthermore, the pillow core extends forward with a pillow tongue, which corresponds to the position of the human cervical vertebrae and gradually decreases in height from back to front. The arrangement of the pillow tongue facilitates the support of the human cervical vertebrae, prevents the human cervical vertebrae from being suspended in the air, and improves the comfort of the pillow.

[0017] The utility model airbag pillow has the following advantages:

[0018] 1. The neck airbag and the head airbag are separately arranged in zones, and the heights of the neck airbag and the head airbag can be independently set and adjusted. The settings of the neck airbag and the head airbag do not interfere with each other, and the settings are more flexible. In this way, they can be easily set one-to-one for the human neck and head, so that both the human neck and the head can be taken into account. The heights of the neck airbag and the head airbag can better meet the sleeping needs, and can also be easily measured according to the physiological curvature of the human body of different users, and high-precision personalized design can be easily carried out according to the person, meeting the requirements and suggestions of doctors for high-quality pillows.

[0019] 2. In addition to the partitioned arrangement of the neck airbag and the head airbag, the head airbag is also composed of two or more sub-airbags. The airbag in the airbag pillow is divided into more than three small airbags, including the neck airbag and the sub-airbag. Compared with a whole large airbag, the space inside the small airbag is small, and the gas has a small flow space. At the same time, the small airbag has a stronger ability to restrain the small amount of gas inside it, resulting in better airbag structure stability of the entire pillow, higher deformation resistance, and not easy to be compressed and deformed to a large extent.

[0020] 3. During sleep, the human body generally sleeps in two different positions: supine and side-lying. In these two different sleeping positions, the front-to-back position of the human body is relatively fixed and will not shift significantly. In contrast, when lying on the left, left side, or lying flat, the left-to-right position of the human body changes significantly and shifts significantly. At this time, if two or more sub-airbags are arranged horizontally in the left and right directions of the pillow, when leaning on one side during side-lying, the sub-airbags on one side will be concentratedly compressed, which is prone to large deformation and poor stability of the airbag. The airbag pillow of this utility model arranges the two or more sub-airbags in the head airbag horizontally from front to back. Under this arrangement, when the human head rests on the head airbag, it is supported by the two or more sub-airbags. Moreover, during sleep, whether lying on the back or lying on the side, the front-to-back position of the human head is relatively fixed and will not shift significantly. The head airbag is always resting on the two or more sub-airbags. The pressure on the head airbag is more uniform, and the stability when leaning on the head is better. The arrangement of the head airbags in which the sub-airbags are horizontally arranged from front to back takes into account the actual sleeping conditions, provides strong support for the balanced force of the pillow, and effectively ensures the pillow's anti-deformation ability.

[0021] 4. The neck airbag and the head airbag are provided. When the head airbag is constructed from two or more sub-airbags, vertically connecting passages can be conveniently provided between the neck airbag and adjacent sub-airbags, and between two adjacent sub-airbags. The separate sub-airbag structures of the neck and head airbags facilitate the provision of passages through the airbags. Based on these provisioning conditions, combined with the provision of the first clearance passage between the neck airbag and adjacent sub-airbags, and the provision of the second clearance passage between two adjacent sub-airbags, the middle of the airbag can be connected, providing space in the middle for other purposes such as height measurement. This allows a height measurement device to be installed through the airbag at the middle position, facilitating height measurement.

[0022] 5. The airbag pillow of the present invention not only has flexible height setting, but can also be measured according to the physiological curvature of the human body of different users, so that the heights of the neck airbag and the head airbag are more in line with sleeping needs; and the setting of the neck airbag and the head airbag including the sub-airbags can make the airbag pillow more stable and more resistant to deformation not only in terms of structural strength but also in terms of balanced pressure distribution. At the same time, it is convenient to set up the first and second make way channels, making the height measurement setting through the airbag more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The preferred embodiment of the utility model airbag pillow is described in detail below with reference to the accompanying drawings:

[0031] like Figure 1 and Figure 2 As shown, an airbag pillow includes a neck airbag 1 and a head airbag 2, which are arranged horizontally from front to back. The neck airbag 1 corresponds to the position of the human neck, and the head airbag 2 corresponds to the position of the human head. The head airbag 2 includes two or more sub-airbags 21, which are arranged horizontally from front to back. A first make way channel 31 that runs vertically through the neck airbag 1 and adjacent sub-airbags 21 is provided, and a second make way channel 32 that runs vertically through the two adjacent sub-airbags 21 is provided.

[0032] In this airbag pillow, the neck airbag 1 is positioned to support the neck, while the head airbag 2 is positioned to support the head. The first and second clearance channels 31 and 32 are used to provide space for other components, such as the height measurement assembly.

[0033] The utility model airbag pillow has the following advantages:

[0034] 1. The neck airbag 1 and the head airbag 2 are separately arranged in zones, and the heights of the neck airbag 1 and the head airbag 2 can be independently set and adjusted. The settings of the neck airbag 1 and the head airbag 2 do not interfere with each other, and the settings are more flexible. In this way, they can be easily set one-to-one for the human neck and head, so that both the human neck and head can be taken into account. The heights of the neck airbag 1 and the head airbag 2 can better meet sleep needs, and can also be easily measured according to the physiological curvature of different users, and high-precision personalized design can be easily performed according to the individual, meeting the requirements and suggestions of doctors for high-quality pillows.

[0035] 2. In addition to the partitioned arrangement of the neck airbag 1 and the head airbag 2, the head airbag 2 is also composed of two or more sub-airbags 21. The airbag in the airbag pillow is divided into a total of more than three small airbags, including the neck airbag 1 and the sub-airbag 21. Compared with a whole large airbag, the space inside the small airbag is smaller, and the gas flow space is smaller. At the same time, the small airbag has a stronger ability to restrain the small amount of gas inside it, resulting in better airbag structure stability of the entire pillow, higher deformation resistance, and less likely to be deformed significantly under pressure.

[0036] 3. During sleep, the human body generally sleeps in two positions: supine and side-lying. In these two positions, the front-to-back position of the human body is relatively fixed and does not shift significantly. In contrast, when lying on the left, left side, or sideways, the left-to-right position of the human body shifts significantly and shifts significantly. In this case, if two or more sub-airbags 21 are arranged horizontally on the left and right sides of the pillow, when leaning on one side during side-lying, the sub-airbags on one side are subjected to concentrated pressure, which can easily cause significant deformation and poor airbag stability. The airbag pillow of the present invention arranges the two or more sub-airbags 21 in the head airbag 2 horizontally from front to back. With this arrangement, when the human head rests on the head airbag 2, it is supported by the two or more sub-airbags 21. Moreover, during sleep, whether lying on the back or side, the human head remains in a relatively fixed front-to-back position and does not shift significantly, and is always supported by the two or more sub-airbags 21. This provides more even pressure on the head airbag 2, and provides better stability when leaning on the head. The arrangement of the head airbag 2 with the sub-airbags 21 arranged horizontally from front to back takes into account the actual sleeping conditions, provides strong support for the balanced force of the pillow, and effectively ensures the pillow's anti-deformation ability.

[0037] 4. The neck airbag 1 and the head airbag 2 are configured. When the head airbag 2 is composed of two or more sub-airbags 21, vertically connecting passages can be conveniently provided between the neck airbag 1 and adjacent sub-airbags 21, and between two adjacent sub-airbags 21. The separate structures of the sub-airbags 21 of the neck airbag 1 and the head airbag 2 facilitate the provision of passages through the airbags. With these installation conditions in place, combined with the provision of the first clearance passage 31 between the neck airbag 1 and adjacent sub-airbags 21, and the provision of the second clearance passage 32 between two adjacent sub-airbags 21, the central portion of the airbags can be connected, providing space for other purposes such as height measurement. This allows a height measurement device to be installed through the airbag in the middle, facilitating height measurement.

[0038] 5. The airbag pillow of the present invention not only has flexible height setting, but can also be measured according to the physiological curvature of different users, so that the heights of the neck airbag 1 and the head airbag 2 are more in line with sleeping needs; and the setting of the neck airbag 1 and the head airbag 2 including the sub-airbag 21 can make the airbag pillow more stable and more resistant to deformation not only in terms of structural strength but also in terms of balanced pressure distribution. At the same time, it is convenient to set the first clearance channel 31 and the second clearance channel 32, making the height measurement setting through the airbag more convenient.

[0039] In the airbag pillow of the present invention, preferably, the number of sub-airbags 21 is two. The number of sub-airbags 21 can be two, three, or more. Since the pillow is relatively small, the stability of the head airbag 2 formed by two sub-airbags 21 is greatly improved. Furthermore, when there are two sub-airbags 21, adjacent sub-airbags 21 can also be provided with the second height measurement and clearance channel 32 to meet height measurement requirements. Compared to other numbers, the configuration of two sub-airbags 21 is simpler.

[0040] The utility model airbag pillow is preferably Figure 3 to Figure 6 As shown, the neck airbag 1 is correspondingly provided with a first inflatable component 40, and the head airbag 2 is correspondingly provided with a second inflatable component 40'; the first inflatable component 40 and the second inflatable component 40' both include an air inlet pipeline 41 and an air outlet pipeline 42, the air inlet pipeline 41 is installed with an air pump 43 and a one-way valve 44, and the air outlet pipeline 42 is provided with a deflation valve 45; in the first inflatable component 40, the air inlet pipeline 41 and the air outlet pipeline 42 are both connected to the neck airbag 1; in the second inflatable component 40', the air inlet pipeline 41 and the air outlet pipeline 42 are both connected to the sub-airbag 21 of the head airbag 2. During operation, when inflating the neck airbag 1 or the head airbag 2, the corresponding air pump 43 works to pump gas into all the sub-airbags 21 in the neck airbag 1 or the head airbag 2 along the air inlet pipe 41; when deflating the neck airbag 1 or all the sub-airbags 21 in the head airbag 2, the corresponding air release valve 45 opens, and the gas in all the sub-airbags 21 in the neck airbag 1 or the head airbag 2 is discharged outward along the air outlet pipe 42.

[0041] The airbag pillow of this invention preferably further comprises air chambers 46 on the air inlet and outlet pipes 41 and 42, each containing a sound-absorbing foam 461. With these air chambers 46 in place, when the neck airbag 1 or all of the sub-airbags 21 in the head airbag 2 are inflated or deflated, gas passes through these chambers 46. Due to the expansion of these chambers 46, the pressure of the gas entering these chambers 46 decreases instantaneously, significantly reducing the noise of air in and out. Furthermore, the sound-absorbing foam 461 acts as a sound absorber, effectively reducing air noise.

[0042] In the present invention's airbag pillow, the air pump 43 is preferably covered with a silicone vibration-damping sleeve 431; the silicone vibration-damping sleeve 431 is connected to the fixing frame 10 via a shock-damping spring 432. Both the silicone vibration-damping sleeve 431 and the shock-damping spring 432 function as shock absorbers, effectively absorbing vibrations during operation of the air pump 43, thereby reducing inflation and deflation noise.

[0043] The utility model airbag pillow is preferably Figure 3 and Figure 7 As shown, the neck airbag 1 is provided with a corresponding neck airbag height measuring assembly 50, and the head airbag 2 is provided with a corresponding head airbag height measuring assembly 50'. Both the neck airbag height measuring assembly 50 and the head airbag height measuring assembly 50' include an automatically rotating rotor 51 and a pull rope 52 wound around the rotor 51. In the neck airbag height measuring assembly 50, the pull rope 52 passes through the first clearance channel 31, and the free end 521 of the pull rope 52 is pulled above the neck airbag 1.

[0044] In the head airbag height measuring assembly 50 ′, the pull rope 52 passes through the second clearance channel 32 , and the free end 521 of the pull rope 52 is pulled above the head airbag 2 .

[0045] In the airbag pillow of the present invention, the automatically rotating rotor 51 provides a fixed-directional pulling force for the drawstring 52, so that the drawstring 52 is always taut and straightened. When the taut and straightened drawstring 52 moves up and down with the rise and fall of the neck airbag 1 or the head airbag 2, the drawstring 52 wound on the rotor 51 is retracted and extended, and the rising and falling displacement of the neck airbag 1 or the head airbag 2 is converted into the retracted and extended length of the drawstring 52. Then, according to the retracted and extended length of the drawstring 52 on the rotor 51, the rising and falling displacement of the neck airbag 1 or the head airbag 2 can be measured to obtain the height of the neck airbag 1 or the head airbag 2.

[0046] With the height-measuring structure of the rotor 51 and the pull cord 52 in this airbag pillow, the vertical displacement of the neck airbag 1 or the head airbag 2 and the retracted length of the pull cord 52 are linearly proportional, resulting in highly accurate height measurement. Furthermore, the pull cord 52 is flexible and highly deformable, perfectly matching the pillow's high deformability. When used to measure the height of the neck airbag 1 or the head airbag 2, the pull cord 52 can be integrated with the pillow, facilitating its connection and installation. More importantly, its installation does not affect the pillow's usability or comfort.

[0047] In the present invention, the automatically rotating rotor 51 may be composed of a rotor body and a recovery spring. The rotor body is rotatable. The recovery spring may be a tension spring wound along the rotor body, or a swing arm mounted on the rotor body, one end of the tension spring connected to the swing arm. The recovery spring may also be a torsion spring mounted on the rotor body, one end of the torsion spring abutting against the fixed frame. The recovery spring may also be a flat scroll spring mounted directly on the rotor body, one end of the flat scroll spring connected to the fixed frame and the other end connected to the rotor body. The structure of the automatically rotating rotor 51 is an existing structure, and the present invention will not elaborate on this in detail.

[0048] In the present airbag pillow, preferably, in the neck airbag height measurement assembly 50, the pull cord 52 extends perpendicularly through the first clearance channel 31; in the head airbag height measurement assembly 50', the pull cord 52 extends perpendicularly through the second clearance channel 32. The pull cord 52 can be arranged at an angle or vertically. Compared to an angled arrangement, a vertical arrangement allows the retracted and extended length of the pull cord 52 to vary proportionally with the pillow height. The pillow height can be directly calculated based on the retracted and extended length of the pull cord 52, simplifying conversion calculations.

[0049] In the airbag pillow of the present invention, a layer 53 is preferably laminated on both the neck airbag 1 and the head airbag 2. The free ends 521 of the two drawstrings 52 in the neck airbag height measurement assembly 50 and the head airbag height measurement assembly 50' are both connected to the layer 53. The free ends 521 of the drawstrings 52 can be connected to the top of the neck airbag 1 or the head airbag 2, or to the top of the pillow core or pillowcase. Alternatively, a layer 53 can be laminated above the neck airbag 1 and the head airbag 2, with the free ends 521 of the drawstrings 52 connected to the layer 53. When the free end 521 of the drawstring 52 is connected to the top of the neck airbag 1 or the head airbag 2, or the top of the pillow core or pillowcase, the structure of the neck airbag 1 and the head airbag 2, or the pillowcase, cannot be destroyed. This makes the connection of the drawstring 52 relatively difficult and limited, often requiring only adhesive bonding, resulting in poor connection security and stability. After the layer 53 is stacked above the neck airbag 1 and the head airbag 2, a hole can be opened in the layer 53, and the drawstring 52 can be passed through the layer 53 and tied to the layer 53. Alternatively, the drawstring 52 and the layer 53 can be sewn together with needle and thread. This simplifies the connection of the drawstring 52 and provides a more secure and reliable connection.

[0050] The airbag pillow of the present invention preferably includes a pillow core 100, wherein the neck airbag 1 and the head airbag 2 are both installed in the pillow core 100. The arrangement of the pillow core 100 serves as packaging and improves the comfort of the pillow.

[0051] In the present invention, the airbag pillow preferably has a tongue 101 extending forward from the pillow core 100. The tongue 101 corresponds to the position of the human cervical vertebrae and gradually decreases in height from back to front. The provision of the tongue 101 facilitates support of the cervical vertebrae, preventing them from being suspended in the air and improving pillow comfort.

[0052] In this airbag pillow, the neck airbag 1 and the head airbag 2 can be completely separate, or their adjacent portions can be connected as a single unit. When these portions are connected as a single unit, the first height measurement and clearance channel 31 is located at the connection between the neck airbag 1 and the head airbag 2.

[0053] In the airbag pillow of the present invention, the sub-airbags 21 within the head airbag 2 can be completely separate, or adjacent sub-airbags 21 can be connected at adjacent locations to form a single unit. When adjacent sub-airbags 21 are connected at adjacent locations to form a single unit, the second height measurement and clearance channel 32 is located at the connection between two adjacent sub-airbags 21.

[0054] The terms "first" and "second" in the above text are only used to distinguish between identical structural members and should not be understood as indicating or implying relative importance.

[0055] For ordinary technicians in the technical field to which the utility model belongs, the utility model can make several simple deductions or substitutions without departing from the concept of the utility model, which should be regarded as falling within the scope of protection of the utility model.
