[0032] With the rise of outdoor camping lifestyle, people have higher requirements for the comfortable experience of outdoor leisure sleep. When camping overnight or taking a short break, most people expect to have an outdoor pillow that is easy to carry and comfortable. However, the current outdoor pillow products on the market have many shortcomings and cannot meet the needs of users.

[0033] On the one hand, the common outdoor pillow on the market mostly adopts the design of inflatable pillow. Although such inflatable pillow is small in size and easy to carry, it has obvious shortcomings in use. For example, the inflatable pillow is relatively hard, lacking sufficient softness and support, resulting in poor user experience. In addition, the fabric of the inflatable pillow often produces a foul odor, affecting the comfort of users. Moreover, the service life of the inflatable pillow is relatively short, and after long-term use, the fabric thereof is easily damaged due to environmental factors (such as ultraviolet rays, humidity, etc.), further reducing the practicality and durability of the product.

[0034] On the other hand, although the traditional sponge-filled pillow can provide a certain softness and comfort, it is large in size and difficult to store and carry. The size and weight of such pillow make it unsuitable for outdoor or car camping and other scenarios that require convenient travel, greatly limiting its application in the outdoor field.

[0035] In view of the problems existing in the prior art, the present application aims to develop a new type of breathable layer inflatable pillow. The pillow, through innovative design and structure, aims to improve the comfort, breathability and durability of the pillow, while maintaining the characteristics of lightweight size and easy to carry. By solving the pain points of existing outdoor pillows, the present application is committed to improving the sleep quality of people in outdoor environments and meeting the needs of comfortable and lightweight travel in outdoor camping life.

[0036] The following will be described in detail in combination with the accompanying drawings. Figures 1-5 Further detailed description will be made to the embodiments of the present application.

[0037] Referring to FIGS. 1 and 2, Figure 1 and Figure 2 as shown, Figure 1 FIG. 1 shows the overall view of the headrest structure in an embodiment of the present application, Figure 2 FIG. 2 shows the cross-sectional schematic view of the headrest structure in an embodiment of the present application.

[0038] One embodiment of this application provides a headrest structure, including an inflatable part 1 and a skin-friendly part 2 arranged and connected sequentially from bottom to top. The inflatable part 1 provides flexible support for the user's neck along a first direction F1 to ensure the headrest's comfort. The skin-friendly part 2 is configured to indent along the first direction F1 after being compressed, conforming to the curvature of the human neck to further enhance comfort. In this embodiment, for ease of explanation, the first direction F1 is defined as the connection direction between the skin-friendly part 2 and the inflatable part 1.

[0039] For details, please refer to [link / reference]. Figure 2 As shown, the inflatable part 1 includes an upper fabric 11, a connecting member 12, and a lower fabric 13 arranged sequentially from bottom to top. The periphery of the lower fabric 13 is connected to the periphery of the upper fabric 11 to form a closed inflatable section 3. The connecting member 12 is arranged within the inflatable section 3. Along the first direction F1, the upper and lower ends of the connecting member 12 are connected to the upper fabric 11 and the lower fabric 13, respectively. After inflation, the connecting member 12 connects the upper fabric 11 and the lower fabric 13, thereby fixing the shape and providing support for the inflatable part 1, so that the overall headrest structure presents a curve suitable for a person's sleeping posture, thereby achieving effective support for the neck and shoulders. In this embodiment, the connecting member can be understood as a common "stiffener" structure in the industry, which can achieve the connection between the upper fabric 11 and the lower fabric 13.

[0040] In some embodiments, multiple connectors 12 are provided and spaced apart along the second direction F2, thereby dividing the interior of the inflation zone 3 into a central region 31 and two oppositely arranged side regions 32. The second direction F2 is perpendicular to the first direction F1.

[0041] by Figure 2 As shown in the example, there are three connectors 12. The area between two adjacent connectors 12 is defined as the middle area 31, and the remaining part is defined as the side area 32. In the first direction F1, the size of the middle area 31 is smaller than the size of the side area 32, so that the surface of the headrest structure forms a concave shape, thereby conforming to the curve of the human neck and improving the comfort of use.

[0042] Depending on actual production needs, the connector 12 can have various structural forms. For example, it can be constructed as a long strip extending along the third direction F3, with its upper and lower ends connected to the upper fabric 11 and the lower fabric 13, respectively. In this application, the structural form of the connector 12 is not specifically limited, as long as it can achieve the adjustment and restriction of the shape of the inflatable part 1.

[0043] Among them, the third direction F3 is perpendicular to the first direction F1 and the second direction F2 respectively.

[0044] In the above embodiment, the upper layer fabric 11 can be made of 6-10 filament high-strength TPU film, which can be welded to the connecting piece 12 and the lower layer fabric 13 by means of a hot-pressing process to ensure the closure of the inflatable section 3. The connecting piece 12 can be made of TPU film or TPU oxford fabric, and the lower layer fabric 13 can be made of TPU or PVC elastic cloth, oxford, nylon fabric, etc.

[0045] In combination Figure 3 as shown, Figure 3 An exploded view of the headrest structure in an embodiment of the present application is shown. In some embodiments, the headrest structure further includes a gas nozzle 5 mounted to the inflatable part 1, which can be used to inflate the inflatable section 3 with air when the headrest is in use, so that the inflatable part 1 expands to achieve flexible support for the neck in the first direction F1, to ensure correct spinal alignment, individual neck and head support, and use comfort.

[0046] Further, according to the height requirements of different users for the headrest, the user can lower the overall height of the headrest structure by releasing gas outwardly, and increase the overall height of the headrest structure by continuously inflating gas into the inflatable section 3, so as to adjust the overall height of the headrest structure by adjusting the amount of inflation, to further improve the use comfort of the user.

[0047] Referring to Figures 1 to 3 as shown, the skin-friendly part 2 includes a filling layer 23, an adhesive layer 22 and a top layer fabric 21 arranged in order from bottom to top. The periphery of the top layer fabric 21 is connected to the periphery of the upper layer fabric 11, which can be welded by means of a hot-pressing process. In the embodiment of the present application, the upper layer fabric 11 functions as a "double-sided tape", connecting the top layer fabric 21 and the lower layer fabric 13 by means of a hot-pressing process, so as to achieve effective connection of the inflatable part 1 and the skin-friendly part 2 in the first direction F1, to ensure the overall structural stability of the headrest structure.

[0048] Specifically, after the top layer fabric 21 is welded to the upper layer fabric 11, a filling section 4 is formed therebetween, and the filling layer 23 and the adhesive layer 22 are accommodated in the filling section 4. The filling layer 23 is connected to the top layer fabric 21 by means of the adhesive layer 22, to achieve effective fixation of the filling layer 23 and prevent abnormal displacement of the filling layer 23 during use.

[0049] The filling layer 23, the adhesive layer 22 and the top layer fabric 21 are connected by means of a hot-pressing process. The filling layer 23 is configured to be stretchable along the first direction F1, and after being pressed, the filling layer 23 is concave downward to fit the neck and shoulder of the human body, improving the use comfort of the headrest structure.

[0050] Referring to Figure 3As shown, in some embodiments, the upper end surface of the filling layer 23 towards the top layer fabric 21 is configured as a planar structure, and the bonding layer 22 is configured as a planar film. The upper end surface of the filling layer 23 and the top layer fabric 21 are fused by the bonding layer 22 to ensure the installation stability of the filling layer 23.

[0051] As shown in Figure 4 , Figure 4 The schematic diagram of the filling layer and the bonding layer in another embodiment of the present application is shown. In some other embodiments, the upper end surface of the filling layer 23 towards the top layer fabric 21 is formed with a pattern, which can be cut on the surface of the filling layer 23. Correspondingly, the surface of the bonding layer 22 is also formed with a pattern consistent with the upper surface of the filling layer 23. The design of the pattern can improve the appearance of the headrest structure, and at the same time, improve the air permeability of the headrest structure, and improve the comfort of use.

[0052] In the above embodiments, the bonding layer 22 includes but is not limited to at least one of a hot melt adhesive film and a TPU film, and the TPU film can be a low filament number TPU film such as a 3-silk or a 6-silk. The filling layer 23 includes but is not limited to at least one of a sponge, a TPE elastomer, a thermoplastic elastomer, and a honeycomb PU aerogel, and can be a high-multiple soft foam material sponge.

[0053] As shown in Figure 2 and Figure 3 In the embodiments of the present application, the top layer fabric 21 is made of a breathable fabric, such as a nylon, a knitted fabric, a velvet, and the like, which has elasticity and breathability. The skin-friendly part 2 can have sufficient breathability while ensuring a certain skin-friendliness, and can easily sweat, so that it does not feel stuffy even after long use, and further improves the comfort of use.

[0054] In some embodiments, along the first direction F1, the bonding layer 22 is arranged between the top layer fabric 21 and the filling layer 23, and fixes the filling layer 23 to the top layer fabric 21. The projection area of the bonding layer 22 formed on the reference surface V1 is greater than or equal to the projection area of the filling layer 23 formed on the reference surface V1, and the projection area of the bonding layer 22 formed on the reference surface V1 is less than the projection of the top layer fabric 21 on the reference surface V1. When the headrest structure is used, the skin-friendly part 2 is depressed downward under the action of pressure, and the gas squeezed out of the filling layer 23 can be discharged from the periphery of the top layer fabric 21 to achieve the effect of air permeability.

[0055] As shown in Figure 3 and Figure 5 , Figure 5A schematic view of the filling layer and the adhesive layer in an embodiment of the present application is shown. In some other embodiments, along the first direction F1, the adhesive layer 22 is used to adhere the filling layer 23 to the top layer fabric 21, and similarly, the projection area of the adhesive layer 22 formed on the reference plane V1 is greater than or equal to the projection area of the filling layer 23 formed on the reference plane V1, so as to achieve effective fixation of the filling layer 23. The difference is that, in the embodiment of the present application, the projection area of the adhesive layer 22 formed on the reference plane V1 is equal to the projection of the top layer fabric 21 on the reference plane V1.

[0056] However, the structure of the adhesive layer 22 being equal in area to the top layer fabric 21 will have some impact on the air permeability of the skin-friendly part 2. In order to ensure the air permeability of the skin-friendly part 2, in the embodiment of the present application, along the first direction F1, a plurality of first through holes 221 are provided through the adhesive layer 22, and a plurality of second through holes 231 are provided through the filling layer 23, the first through holes 221 and the second through holes 231 are arranged one by one, so that the gas squeezed out of the filling layer 23 is discharged through the first through holes 221 and the second through holes 231, so as to achieve the effect of air permeability.

[0057] Specifically, the diameters of the first through holes 221 and the second through holes 231 can be adjusted according to the actual design scheme, and are preferably between 1mm and 3mm. In the embodiment of the present application, as shown in Figure 4 the first through holes 221 and the second through holes 231 can be configured as rectangles and arranged one by one.

[0058] In some other embodiments, the first through holes 221 and the second through holes 231 can also be configured as circles or other shapes, which are not described herein.

[0059] It can be understood that, for the case that the area of the adhesive layer 22 is smaller than that of the top layer fabric 21, first through holes 221 can also be provided on the adhesive layer 22 and second through holes 231 can also be provided on the filling layer 23 according to design requirements, so as to improve the air permeability and sweat discharge capacity of the skin-friendly part 2 and improve the use comfort of the headrest structure.

[0060] In the above embodiments, in order to facilitate description, the reference plane V1 is defined as a plane perpendicular to the first direction F1.

[0061] In addition, in some embodiments, the present application also provides an outdoor inflatable product (not shown), which can be specifically an inflatable bed for outdoor use, and the inflatable bed at least comprises a headrest structure as shown in the above embodiments.

[0062] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0063] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
