Description
Technical Field
The present disclosure relates to the field of sleep, and more particularly to a sleep pillow.
Background
Sleep pillows are a sleep aid for guiding the breathing of a user and are being increasingly used. The sleeping pillow can be used as a throw pillow and is held at the chest and abdomen. It uses methods that have been proven both naturally and clinically to help the user relax and calm the brain so that the user can more easily fall asleep and sleepy.
Specifically, the natural relaxation response of the body can be evoked by guided breathing fluctuations of the sleeping pillow. For example, when a user holds a sleep pillow, the user may feel fluctuations in the breathing rhythm of the sleep pillow. Scientific research has demonstrated that such guided breathing fluctuations can help the user concentrate on, feel calm, and relieve stress, thereby helping to fall asleep and sleep.
Disclosure of Invention
It is an object of the present disclosure to provide an improved sleep pillow which is at least effective in improving the amplitude of the undulations of the sleep pillow.
According to one aspect of the present disclosure, a sleep pillow is provided. The sleeping pillow comprises: the movement comprises a telescopic air bag; and a core made of an elastic material and wrapping the movement, wherein at least a portion of the core covering the stretchable bladder is adapted to undulate with deformation of the stretchable bladder; wherein at least a part of the pillow core is provided with a hole array.
It will be appreciated that due to the provision of the array of holes on at least a portion of the pillow core of the present disclosure, the relief amplitude of that at least a portion of the sleep pillow can be effectively improved.
In some embodiments, the deforming of the collapsible balloon comprises expanding the collapsible balloon under inflation and/or collapsing the collapsible balloon under deflation. In this way, the telescopic balloon can be allowed to deform simply under inflation/deflation.
In some embodiments, the holes in the array of holes extend from the outer surface of the pillow core towards the core a predetermined distance, the ratio between the predetermined distance and the thickness of the pillow core at the pillow core location where the holes are located being between 30% and 80%. In these embodiments, the above ratio ranges may allow the pillow core to better achieve an increase in the relief amplitude.
In some embodiments, the predetermined distance of holes in the array of holes may be arranged to have one of the following characteristics: a. the predetermined distances of all holes are the same as each other; b. the predetermined distances of all holes are different from each other; or c. said predetermined distances of a part of the holes in said array of holes are the same, while said predetermined distances of another part of the holes are different from each other. It will be appreciated that in these arrangements, the predetermined distance arrangement of the holes in the appropriate hole array may be selected as desired.
In some embodiments, the predetermined distance of the holes in the array of holes is proportional to the thickness of the pillow core at the pillow core location where the holes are located. That is, the thicker the thickness is, the greater the predetermined distance of the hole at the corresponding position can be selected, so that the enhancement of the relief amplitude can be more effectively achieved.
In some embodiments, the apertures of the apertures in the array of apertures range in size from 3mm to 15 mm. In these embodiments, the selected range of pore sizes may be selected according to the overall physical dimensions of the pillow core, and may assist in achieving increased relief amplitude.
In some embodiments, the spacing between the holes in the array of holes is in the range of 10mm to 30 mm. In these embodiments, the spacing between the selected range of holes may be selected based on the overall physical dimensions of the pillow core, and may assist in achieving increased relief amplitude.
In some embodiments, the shape of the holes in the array of holes comprises at least one of: round, oval, triangular, square, and rectangular. The present disclosure is not limited to the shape of the holes, and regular shapes and irregular shapes such as circles, ovals, triangles, squares, rectangles, etc., are within the scope of the present disclosure, and the above-described regular shapes may be conveniently manufactured.
In some embodiments, the shore hardness of the pillow core is in the range of 40 degrees to 50 degrees. In these embodiments, the selected range of shore hardness may be better suited to the desired softness and resiliency requirements of the sleep pillow.
In some embodiments, the ratio is inversely proportional to the shore hardness of the pillow core. That is, the higher the shore hardness, the lower the above ratio may be set. Thus, the enhancement of heave amplitude can be adjusted by balancing both the ratio and shore hardness
In some embodiments, the spacing is inversely proportional to the shore hardness of the pillow core. That is, the higher the shore hardness, the lower the above-mentioned spacing may be set. Thus, both the spacing and the shore hardness can be balanced to adjust the rise and fall amplitude enhancement.
In some embodiments, the elastic material comprises at least one of: plastic foam, foamed plastic, rubber, thermoplastic elastomer and soft polyvinyl chloride. It will be appreciated that these materials can effectively achieve a resilient tactile sensation and easily achieve an array of apertures thereon.
In some embodiments, the array of holes is disposed on at least a portion of an area of at least one of the upper and lower outer surfaces of the pillow core. It will be appreciated that arranging in this manner may facilitate an increase in the amplitude of relief of the primary surface of the sleep pillow as perceived by the user.
In some embodiments, the cartridge further comprises a housing and a gas pumping and control member disposed inside the housing, the retractable bladder being disposed on at least one side of the exterior of the housing, the gas pumping and control member being in gas communication with the retractable bladder and being arranged for inflating or deflating the retractable bladder. In this way, it is possible to allow the gas pumping and control components to be hidden inside the pillow core, while making the layout of the movement more compact.
In some embodiments, further comprising a gas pumping and control member disposed outside the pillow core, the gas pumping and control member in gas communication with the inflatable bladder and arranged to inflate or deflate the inflatable bladder. In this way, a layout of the gas pumping and control components outside the pillow core can be achieved, thereby increasing the design freedom.
It should also be appreciated that the descriptions in this summary are not intended to limit key or critical features of embodiments of the disclosure, nor are they intended to limit the scope of the disclosure. Other features of embodiments of the present disclosure will become apparent from the following description.

Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure have been shown in the accompanying drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustration purposes only and are not intended to limit the scope of the present disclosure.
As described above, sleeping pillows are increasingly being used, which have a breathing relief function for helping a user sleep.
Fig. 1 shows a general external structural view of a conventional sleeping pillow, and fig. 2 shows an exploded structural view of a conventional sleeping pillow. As shown in fig. 1 and 2, such a conventional sleeping pillow 1' mainly includes a core 2' and a core 3', wherein the core 3' is generally made of an elastic material and is arranged to wrap the core 2', and the outside of the core 2' is provided with a stretchable bag 21', and the stretchable bag 21' may be in direct contact with the inside of the core 3 '. In operation, the inflatable bladder 21' may be arranged to deform under inflation or deflation, thereby entraining at least a portion of the core 3' overlying the inflatable bladder 21' to undulate with the deformation of the inflatable bladder. By controlling the relief (in particular, the breathing relief) of the stretchable bladder 21', the pillow core 3' can be guided to follow the relief, thereby realizing the relief function (in particular, the breathing relief function) of the sleeping pillow 1 '.
As a typical usage, a user may hug a sleeping pillow to fall asleep. In this case, the abdomen and palm of the user may contact the outer surface of the sleep pillow and feel such undulations (particularly, respiratory undulations) of the sleep pillow. Notably, the amplitude of the undulations of the sleep pillow cannot be too weak, otherwise the user may not adequately feel such undulations. Thus, the amplitude of this fluctuation of the sleep pillow should be large enough to be adequately perceived by the user.
However, the inventors noted that: the conventional increase in the amplitude of such undulations (in particular, breathing undulations) of a sleeping pillow is generally achieved in two ways, namely: first, increasing the heave amplitude of the telescopic airbag; and in a second way, the thickness of the pillow core is reduced. Both of these approaches, however, have their own drawbacks.
In particular, the first approach has a disadvantage in that it may cause excessive noise as well as power consumption because a higher power air pump is required to drive the telescopic air bag, and at the same time vibration of the air pump or air flow inside the sleeping pillow may also cause greater noise. Further, in order to reduce such noise, a more complicated noise reduction design or the use of more expensive noise absorbing materials may be required, which results in an increase in cost. On the other hand, the noise is not reduced significantly.
The second approach has a disadvantage in that although it can effectively increase the amplitude of the undulation of the sleeping pillow, the elasticity or softness of the pillow core is insufficient due to the thickness reduction of the pillow core, thereby failing to give the user a better tactile experience.
It is an object of the present disclosure to provide an improved sleep pillow that increases the amplitude of such undulations (in particular, respiratory undulations) of the sleep pillow in a manner that is entirely different from the two approaches described above, while avoiding the disadvantages of the two approaches described above. Specifically, the concept of the present disclosure is: an array of holes is provided in at least a portion of the core covering the inflatable bladder to increase the amplitude of such undulations (particularly, respiratory undulations) of the sleeping pillow.
In order to more clearly understand the specific implementation of the above-described concept of the present disclosure, the specific structure of the sleeping pillow of the present disclosure will be described below with reference to fig. 3 to 6.
Fig. 3 illustrates an overall external appearance structure diagram of a sleep pillow according to an exemplary embodiment of the present disclosure, and fig. 4 illustrates an exploded structure diagram of a sleep pillow according to an exemplary embodiment of the present disclosure.
As shown in fig. 3 and 4, the sleeping pillow 1 of the present disclosure may include a core 2 and a pillow core 3, wherein the pillow core 3 may be made of an elastic material and arranged to encase the core 2.
It should be noted here that although not shown in fig. 3 and 4, in some embodiments, the sleeping pillow 1 may further include other components besides the movement 2 and the pillow core 3, such as a pillow case (not shown), which may be sleeved outside the pillow core 3, so as to avoid the exposure of the pillow core 3, while providing a better tactile experience for the user. Further, the present disclosure is not limited to the external shape of the sleep pillow 1, and it may be, for example, a typical flat external shape, or various shapes such as other regular or irregular shapes of an elongated shape.
The function of the movement 2 is to provide at least a telescopic bladder 21 which can be deformed so that at least a portion of the core 2 covering the telescopic bladder 21 can undulate (in particular, respiratory undulation) with the deformation of the telescopic bladder. The present disclosure is not limited to a particular implementation of the deformation of the retractable balloon. In particular, in some embodiments, the deformation of the collapsible bladder 21 may include the expansion of the collapsible bladder 21 under inflation and/or the contraction under deflation. It will be appreciated that in this way, the deformation of the telescopic balloon 21 can be made easier and easier.
In some embodiments, cartridge 2 may further include a housing 22 and a gas pumping and control component (not shown) disposed inside housing 22, wherein retractable bladder 21 may be disposed on at least one side of the exterior of housing 22. The gas pumping and control means function to communicate with the inflatable bladder 21 and to inflate or deflate the inflatable bladder 21. Typically, the gas pumping and control means may for example comprise an air pump and an air valve.
It should be noted here that although in the above embodiments it is mentioned that the movement 2 comprises the housing 22 and the gas pumping and controlling means (not shown), in still other embodiments it is possible that the movement 2 does not comprise the housing 22 and/or the gas pumping and controlling means (not shown) (even only the stretchable bladder 21 is comprised), in which case the gas pumping and controlling means such as the gas pump or the gas valve may be arranged outside the pillow core and the stretchable bladder 21 may be in gas communication with the gas pumping and controlling means via a gas line. It will be appreciated that the embodiment in which cartridge 2 includes housing 22 and the gas pumping and control components disposed within housing 22 may allow the primary actuation components of the sleep pillow to be encased within the pillow core, providing a more compact cartridge structure and sleep pillow structure, as compared to embodiments in which cartridge 2 includes only a retractable bladder 21.
In some embodiments, the collapsible bladder 21 may be in direct physical contact with the pillow 3, thereby directly entraining at least a portion of the pillow 3 covering the collapsible bladder 21 to collapse (e.g., breathing relief) as the collapsible bladder 21 deforms. In still other embodiments, the inflatable bladder 21 may also apply undulating pressure to the pillow 3 indirectly (e.g., via a material between the pillow 3 and the inflatable bladder 21), thereby causing undulations to cover at least a portion of the pillow 3 of the inflatable bladder 21.
In some embodiments, a control circuit board such as a PCB circuit board (not shown) may also be provided within movement 2, and the above-described gas pumping and control components such as a gas pump or gas valve may operate under the control of the PCB circuit board.
The pillow core 3 is used for wrapping the movement 2 and providing soft touch feeling for the sleeping pillow. The pillow core 3 is typically formed of an elastic material so that the pillow core 3 has a resilient force, which is advantageous for providing a sleeping pillow with a pleasant feel and a moderate undulating amplitude.
In some embodiments, the elastic material may include at least one of the following: plastic foam, foamed plastic, rubber, thermoplastic elastomer (TPE) and soft polyvinyl chloride (PVC). As a further example, the rubber may include, for example, silicone rubber; while the thermoplastic elastomer (TPE) may comprise a thermoplastic polyurethane elastomer (TPU).
To achieve the wrapping of the movement 2, in some embodiments, the interior of the pillow core 3 may be provided with a recess 36, the shape and size of this recess 36 being compatible with the external shape and size of the movement 2, so as to (tightly) wrap the movement 2 inside. To facilitate the placement of the movement 2 in the recess of the aforementioned core 3, in some embodiments the core 3 may be formed by, for example, splicing two parts, for example, a first core part 31 and a second core part 32 as shown in fig. 4. In particular, the dimensions of the two portions may be the same or different. It should be understood that the joining of the two parts of the core 3 is merely exemplary and that in still other embodiments, it is possible that the core 3 may be joined from more parts.
To facilitate the user's handling of the sleeping pillow, in some embodiments the sleeping pillow 1 may further comprise a handling panel (not shown) which may be positioned at the outer surface of the sleeping pillow 1 or located away from the outside of the pillow core 3. In still other embodiments, the steering panel (not shown) may communicate with the movement 2 of the sleeper 1 in a wired or wireless manner to send control signals to a control circuit board, such as a PCB circuit board, within the movement 2 to steer gas pumping and control components, such as an air pump or valve, to inflate or deflate the inflatable bladder 21. In embodiments in which the control panel is connected in a wired manner to the movement 2 within the sleeping pillow 1, the electrical connection between the control panel and the movement 2 may pass through the pillow core 3 to connect with the electrical components inside the movement 2.
As previously mentioned, the present disclosure is directed to increasing the amplitude of the undulations (particularly, respiratory undulations) of a sleep pillow in a manner that is quite different from the conventional two. For this purpose, the idea of the present disclosure consists in providing an array of holes on at least a portion of the pillow core covering the above-mentioned retractable air-bag. It will be appreciated that the arrangement of the array of holes contributes to the enhancement of the relief amplitude of the pillow core at the respective location.
As shown in fig. 3 and 4, an array of holes 33 may be provided on at least a portion of the core 3 covering the aforementioned retractable bladder 21.
In some embodiments, the pillow core 3 may have an upper outer surface 34 and a lower outer surface 35 in the thickness direction, and the hole array 33 may be provided on at least a part of the area of at least one of the upper outer surface 34 and the lower outer surface 35. It will be appreciated that this is advantageous because the user typically uses the upper outer surface (which corresponds to the upper outer surface 34 of the pillow core 3) or the lower outer surface (which corresponds to the lower outer surface 35 of the pillow core 3) of the sleeping pillow 1 in the thickness direction to attach to the abdomen of the user, which enables the user to more easily feel the enhancement in the amplitude of the relief of the pillow core brought about by the arrangement of the hole array 33 described above, due to the arrangement of the hole array 33 on at least a partial area of at least one of the upper outer surface 34 and the lower outer surface 35 of the pillow core 3. It should be understood that the above-described distribution of the array of holes 33 on the upper and/or lower outer surfaces 34, 35 of the pillow core 3 is only an example, and that the array of holes 33 may be distributed on other locations on the pillow core 3 than the upper and lower outer surfaces 34, 35, depending on the actual needs. In particular, in some embodiments, the array of holes 33 may be distributed over all the outer surfaces of the pillow core 3. Of course, in still other embodiments, other outer surfaces of the array of holes 33 than the upper outer surface 34 and the lower outer surface 35 on the pillow core 3 are also possible, as other outer surfaces of the pillow core 3 than the upper outer surface 34 and the lower outer surface 35 are not the main body surfaces of the sleeping pillow 1 perceived by the user.
To more clearly show the extension and distribution of the holes in the hole array 33 within the pillow core 3, fig. 5 shows a schematic view of a partial cross-sectional structure of the pillow core in the sleeping pillow according to an exemplary embodiment of the present disclosure, and fig. 6 shows a schematic view of a partial a of the pillow core in fig. 5.
By way of example only, as shown in fig. 5, in some embodiments, the holes in the array of holes 33 may extend toward the movement a predetermined distance H at position B, while the thickness of the pillow core at its corresponding position may be H, where the extending distance H is less than the thickness H described above. Furthermore, in still other embodiments, the holes in the array of holes 33 may be evenly distributed over the pillow core. However, this is not limiting, and in other embodiments, a predetermined distance H equal to H, and/or an uneven distribution of holes on the pillow core is possible.
It will be appreciated that the distance h that the holes in the array of holes 33 extend from the outer surface of the pillow core towards the core 2, the size of the holes, the shape of the holes and the spacing between the holes all have an effect on the relief amplitude of the pillow core 3.
In order to achieve an optimal influence on the relief amplitude of the pillow core 3, the ratio between the above-mentioned predetermined distance H and the thickness H of the pillow core 3 at the pillow core position where the holes are located may be chosen between 30% and 80% in some embodiments. In still other embodiments, the aperture size of the holes in the hole array 33 may be selected in the range of 3mm to 15 mm. In still other embodiments, the shape of the holes in the hole array 33 may include at least one of: circular, oval, triangular, square, rectangular, or a combination thereof. In still other embodiments, the spacing between the holes in the array of holes 33 may be selected to be in the range of 10mm to 30 mm.
It should be understood that the above-described arrangements of ratios, aperture sizes, shapes and spacings with respect to the extension distance H and thickness H of the holes are merely examples, and that ratios, aperture sizes, spacings and other hole shapes outside the above-described selection range are also possible in other embodiments.
In addition, the predetermined distance h of the holes in the hole array 33, the size of the holes, the shape of the holes, and the spacing between the holes may also be different depending on the location of the pillow core where the holes are located, the thickness and hardness (e.g., shore hardness) of the pillow core at that location.
For example, in some embodiments, the predetermined distance h of the holes in the array of holes may be the same in some areas of the pillow core (e.g., the areas corresponding to the central portions of the upper or lower outer surfaces 34, 35 of the pillow core 3) and may be different in other areas of the pillow core (e.g., the areas corresponding to the edge portions of the upper or lower outer surfaces 34, 35 of the pillow core 3). In other embodiments, the predetermined distance of the holes in the array of holes 33 may be selectively arranged to have any of the following characteristics: a. the predetermined distances of all holes are the same as each other; b. the predetermined distances of all holes are different from each other; or c. the predetermined distances of some of the holes in the array of holes 33 are the same, while the predetermined distances of other parts of the holes are different from each other. For example, in some embodiments, a portion of the holes having the same predetermined distance may be located in a portion of the pillow core 3 (e.g., a region away from the edge of the pillow core), while a portion of the holes having different such predetermined distances may be located in another portion of the pillow core 3 (e.g., a region near the edge of the pillow core). In particular, in some embodiments, the predetermined distance H of the holes in the hole array 33 may be proportional to the thickness H of the pillow core 3 at the pillow core location where the holes are located. In still other embodiments, the ratio between the predetermined distance H and the thickness H of the core 3 at the core location where the holes are located may be in a linear or non-linear inverse relationship with the shore hardness of the core, i.e. the higher the shore hardness of the core, the lower the ratio may be set in accordance with the above-mentioned linear or non-linear inverse relationship. For example, in the case where the shore hardness of the pillow core is relatively high (e.g., exceeds a predetermined value such as 45 degrees), the above ratio may be selected to be set to be less than or equal to 50%, i.e., not more than half the thickness of the pillow core at the location. In still other embodiments, the spacing between the holes in the array of holes 33 may also be set in a linear or non-linear inverse relationship to the shore hardness of the pillow core, i.e., the higher the shore hardness of the pillow core, the smaller the spacing may be set in accordance with the above-described linear or non-linear inverse relationship.
To make the actual effect of the sleeping pillow with the hole array of the present disclosure more clear, fig. 7 shows the result of a comparative experiment of the fluctuating pressure of the sleeping pillow with respect to the conventional sleeping pillow according to the disclosed exemplary embodiment, wherein both the sleeping pillow of the present disclosure and the conventional sleeping pillow have only the stretchable air bag on one side of the movement, while the hole array of the present disclosure is disposed on the upper and lower surfaces of the pillow core of the sleeping pillow in the thickness direction.
Here, for convenience of description, it is assumed that a side of the sleep pillow of the present disclosure and the conventional sleep pillow having the corresponding stretchable air bag is a front side, and a side opposite to the above-described front side is a rear side. It should be understood that the use of the terms "front side" and "back side" does not constitute any limitation on the structure of the sleeping pillow, in other embodiments, the side with the corresponding inflatable bladder may also be considered the back side, and the side without the corresponding inflatable bladder may also be considered the front side.
In the comparative experiment of fig. 7, the fluctuating pressures generated by the sleep pillow of the present disclosure and the conventional sleep pillow on the front side (i.e., the side having the corresponding stretchable airbag) and the back side (i.e., the side not having the corresponding stretchable airbag), respectively, were detected. It will be appreciated that the relief pressure described above may be used to reflect the magnitude of the relief of a sleeping pillow during normal operation.
As shown in fig. 7, in the comparative experiment on the front side, the relief pressure on the front side of the sleep pillow with the hole array of the present disclosure can be increased from 24.2N to 29.6N, which is an increase in relief amplitude of about 22%, relative to the conventional one without the hole array. In contrast, in the comparative experiments on the back side, the back side relief pressure of the sleep pillow with an array of holes of the present disclosure may be increased from 18.8N to 20N, which is also a significant increase, relative to conventional back side relief pressures of sleep pillows without an array of holes. It is to be noted that the above experimental result of fig. 7 reflects the case where the front side is arranged with the corresponding stretchable bag and the rear side does not have the corresponding stretchable bag, and if the rear side (or the other side than the front side and the rear side) is also arranged with the corresponding stretchable bag, the rear side (or the other side than the front side and the rear side) can also achieve the 22% lifting effect similar to the front side described above.
The structure of the various embodiments of the sleep pillow of the present disclosure and the related effects have been described in detail above. It will be appreciated that by arranging a corresponding array of holes, the sleep pillow of the present disclosure may significantly increase the relief pressure or amplitude of the sleep pillow, which may be accomplished without increasing the amplitude of the relief of the retractable bladder and/or reducing the thickness of the pillow core. At the same time, the noise and power consumption of the sleep pillow of the present disclosure may be lower and/or the thickness of the pillow core may be thicker relative to conventional sleep pillows having the same amplitude of undulations, thereby giving the user a better tactile experience.
While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive; the invention is not limited to the disclosed embodiments. Other variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the disclosure, and the appended claims.
In the claims, the word "comprising" does not exclude other elements, and the indefinite article "a" or "an" does not exclude a plurality. A single element or other unit may fulfill the functions of several items recited in the claims. The mere fact that certain features are recited in mutually different embodiments or in dependent claims does not indicate that a combination of these features cannot be used to advantage. The scope of the application encompasses any possible combination of the features recited in the various embodiments or the dependent claims without departing from the spirit and scope of the present application.
Furthermore, any reference signs in the claims shall not be construed as limiting the scope of the invention.
