Description

Technical Field

[0001] The present application belongs to the technical field of waist and neck health care equipment, and in particular relates to an inflatable pillow for human body to lean against. Background Art

[0002] Nowadays, competition in society is fierce, and there are many people who often study and work and sit for long periods of time. Using a good neck and waist pillow can evenly distribute the force points, which is beneficial to reduce neck and waist pain and sciatica, and can relieve neck and waist muscle stiffness, numbness, etc., especially relaxing the muscles has a good preventive and therapeutic effect on cervical and lumbar muscle strain, lumbar disc herniation and other waist diseases.

[0003] Traditional neck and waist pillows are of fixed shape, difficult to store and take up a lot of space, making them inconvenient to carry around. Moreover, traditional neck and waist pillows cannot adjust their support status according to changes in body shape during use, resulting in poor effect in relieving neck and waist discomfort, and may even leave indentations.

[0004] In response to this, foldable neck and lumbar pillows have appeared on the market. These foldable pillows generally have built-in airbags that use the expansion or contraction of the airbags to achieve overall deformation. When contracted, the volume can be reduced, making the neck and lumbar pillows easy to store and reducing the space they occupy. However, this type of pillow structure with a built-in airbag requires an air pump to inflate the airbag before use, and as the airbag is inflated, the pillow can return to its original shape. As can be seen, this pre-operation is very cumbersome, and the air pump also generates noise during the process of inflating the airbag, which is not conducive to practical use. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide an inflatable pillow to solve the technical problems that the inflation structure of the inflatable pillow in the prior art requires a pre-inflation operation and the inflation operation is prone to generate noise.

[0006] To achieve the above objectives, the technical solution adopted in this application is to provide an inflatable pillow, comprising:

[0007] airbags;

[0008] an expansion member filled in the airbag, wherein the expansion member can be compressed under the action of an external force to shrink the inflatable pillow;

[0009] The air valve is arranged on the airbag. When the air valve is opened, the airbag releases pressure, causing the expansion member to automatically expand and drive the inflatable pillow to recover.

[0010] The beneficial effect of the inflatable pillow provided by the present application is that: compared with the existing technology, the inflatable pillow of the present application has re-improved the inflation structure, and the interior of the airbag is filled with an expansion piece, and the airbag is provided with an air valve. The airbag is depressurized by opening the air valve, so that the compressed expansion piece can automatically expand and recover, so that the inflatable pillow can be automatically formed, making the entire front operation simple, convenient and easy to operate.

[0011] Compared to a structure in which the airbag is placed inside the inflatable pillow and the airbag is inflated to restore the inflatable pillow, the structure of the inflatable pillow of the present application is to place the airbag outside the expansion member, and to use the force of the expansion member automatically restoring its expansion after being pressed and contracted to support the airbag, thereby automatically forming the inflatable pillow. As can be seen, during the pre-installation operation, the user does not need to inflate the airbag. After opening the air valve, the airbag can automatically release pressure, and the expansion force of the expansion member can automatically support the airbag, so that the inflatable pillow is automatically formed. The entire pre-installation operation is very simple and easy to use. The inflatable pillow can be automatically formed, effectively improving the convenience of use. In addition, since there is no need to use an air pump to inflate the airbag, a silent design of air pump-free air valve inflation is achieved, eliminating the noise impact of the air pump on the airbag inflation, and effectively playing a silent role.

[0012] In addition, during use, the user can open and close the air valve, allowing the inflatable pillow to adjust its shape as it contacts the user's body. This helps adapt to the changes in the user's body, allowing the user's neck and waist to rest comfortably, allowing the muscles to fully relax, and improving health care effects.

[0013] The structure of the expansion element is improved. The expansion element is a memory foam. The high-resilience memory foam is used to support the airbag, so that the expansion element can return to its original shape after each expansion, effectively ensuring that the inflatable pillow can automatically form.

[0014] In one embodiment, the expansion member is provided with a plurality of through slots that penetrate the expansion member. This facilitates internal pressure relief and allows the expansion member to actively expand from a compressed state and return to its original state, effectively increasing the expansion recovery speed of the expansion member and shortening the lead-in operation time.

[0015] In one embodiment, the through-slots on the expansion element extend parallel to the same direction. This allows the through-slots on the expansion element to release pressure and air in the same direction, allowing the element to actively expand and return to its original shape. Furthermore, this increases the compression range of the expansion element, allowing the user to compress and roll up the inflatable pillow for storage, minimizing its size.

[0016] In one embodiment, the expansion member is further provided with an elastic member, which is disposed in the through slot and extends along the length of the through slot. The elastic force of the elastic member is utilized to drive the expansion member to actively expand and restore to its original shape, thereby effectively improving the initiative of the expansion member to automatically expand.

[0017] The structure of the air valve has been improved. The air valve comprises a valve body and a valve cover. The valve body is mounted on the mounting hole of the airbag. At least a portion of the valve cover is movably connected to the valve body and can be opened and closed on the valve port of the valve body. This allows the valve cover to be movably connected to the valve body, allowing the valve cover to rotate and open and close on the valve body, thereby opening and closing the valve port on the valve body and allowing the airbag to release pressure.

[0018] In one embodiment, the valve body is further provided with an airtight switch for opening and closing the valve port. Using the airtight switch on the valve port to open the valve port allows the airbag to exhaust or inhale, quickly fine-tuning the shape of the inflatable pillow and thereby increasing the flexibility of fine-tuning the inflatable pillow.

[0019] In one embodiment, the valve cover is provided with a convex ring extending toward the valve body. When the valve cover is covered on the valve body, the convex ring surrounds the outer circumference of the airtight switch, thereby improving the sealing effect.

[0020] In one embodiment, the air valve is further provided with a sealing ring, which is arranged on the valve body and is used to seal the gap between the valve body and the edge of the mounting hole of the airbag, effectively ensuring the sealing of the mounting part of the air valve on the airbag.

[0021] The structure of the entire inflatable pillow is improved, and the inflatable pillow also includes an outer bag, which is used to hold the rolled-up inflatable pillow. In this way, the user can put the rolled-up inflatable pillow into the outer bag for easy storage or carrying. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0037] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0038] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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 cannot be understood as a limitation on this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0040] Traditional neck and lumbar pillows have a fixed shape, making them difficult to store and space-consuming, making them inconvenient to carry around. Furthermore, they cannot adjust their support to the user's body shape, resulting in inadequate relief for the neck and waist, and can even leave marks.

[0041] In the related art, there are foldable neck and waist pillows. Such foldable pillows generally have built-in air bags, which use the expansion or contraction of the air bags to achieve overall deformation. When contracted, the volume can be reduced, making the neck and waist pillows easy to store and reducing the space occupied. However, this type of pillow structure with a built-in air bag requires an air pump to inflate the air bag before use, and as the air bag is inflated, the pillow can be restored to its original shape for use. It can be seen that this pre-operation is very cumbersome, and the air pump also generates noise during the process of inflating the air bag, which is not conducive to actual use.

[0042] In addition, the shape of the pillow with a built-in airbag is fixed after the airbag is inflated, and the user can only use the pillow with this fixed shape. It cannot be adjusted according to the contact between the user's body and the pillow, resulting in the user's body muscles not being effectively relaxed, making it difficult to achieve health care effects.

[0043] Therefore, the present invention provides a novel inflatable pillow with a redesigned overall structure. This design allows for easy storage and reduces the amount of pre-use manipulation required. The pillow automatically returns from its storage state to its active state, making it easy for the user to use while eliminating the noise associated with pre-inflation. Furthermore, the inflatable structure of the present invention allows for fine-tuning during use, facilitating adaptation to the user's physical changes. This effectively addresses the issues with conventional inflatable pillows, which require pre-inflation manipulation and lack the ability to fine-tune the support state. This invention is now described in detail.

[0044] It should be noted that the inflatable pillow in the embodiment of the present application can be a lumbar pillow or a neck pillow, and both can adopt the structure of the inflatable pillow in the present application.

[0045] Please also refer to Figure 1 、 Figure 2 and Figure 3 The inflatable pillow provided in the embodiment of the present application includes an airbag 1, an expansion member 2 and an air valve 3.

[0046] The airbag 1 is wrapped around the exterior of the expansion member 2. After the expansion member 2 inflates and recovers, the airbag 1 is propped up and shaped into the entire pillow structure. It can be understood that in its normal state, the expansion member 2 takes the shape of the entire inflatable pillow, with the airbag 1 surrounding it. The shape of the expansion member 2 can be configured as a neck pillow, lumbar pillow, or other pillow or cushioning member, as needed, without specific limitation.

[0047] The expansion member 2 is filled in the airbag 1. The expansion member 2 can be compressed under the action of external force (such as manual squeezing) to shrink or roll up the entire inflatable pillow, which is beneficial to reducing the occupied space and making it convenient to store and carry.

[0048] The air valve 3 is provided on the airbag 1. When the air valve 3 is opened, the airbag 1 can release pressure, so that the expansion member 2 can automatically expand to support the airbag 1 and drive the inflatable pillow to restore to a usable state.

[0049] Compared with the prior art, the inflatable pillow provided in the embodiment of the present application has a new improvement on the inflation structure. The interior of the airbag 1 is filled with an expansion member 2, and the airbag 1 is provided with an air valve 3. The airbag 1 is depressurized by opening the air valve 3, so that the compressed expansion member 2 can automatically expand and recover, so that the inflatable pillow can be automatically formed, making the entire front operation simple and convenient, easy to operate, and very practical.

[0050] Compared to the structure of the above-mentioned related art in which the airbag 1 is arranged inside the inflatable pillow and the inflatable pillow is expanded and restored by inflating the airbag 1, the structure of the inflatable pillow of the present application is to arrange the airbag 1 outside the expansion member 2, and use the force of the expansion member 2 to automatically restore the expansion after being pressed and contracted to support the airbag 1, so that the inflatable pillow is automatically formed. It can be seen that in the pre-operation, the user does not need to inflate the airbag 1. After opening the air valve 3, the airbag 1 can automatically release pressure and use the expansion force of the expansion member 2 to automatically support the airbag 1, so that the inflatable pillow is automatically formed. The entire pre-operation is very simple and easy to use. The inflatable pillow can be automatically formed and the user can use it immediately, which effectively improves the convenience of use.

[0051] In addition, since there is no need to use an air pump to inflate the airbag 1, a silent design of inflation without an air pump air valve 3 is achieved, eliminating the noise impact generated by the air pump on the inflation of the airbag 1, and effectively playing a silent role.

[0052] In addition, during use, the user can open and close the air valve 3, allowing the inflatable pillow to adjust its shape according to the changes in contact with the user's body, thereby achieving fine-tuning. This helps adapt to the changes in the user's body, allowing the user's neck and waist to rest comfortably, allowing the muscles to fully relax, and thus improving the health care effect.

[0053] Regarding the structure of the expansion member 2, in one embodiment of the present application, the expansion member 2 in the inflatable pillow can preferably be memory sponge, and specifically, sponge with high resilience can preferably be used.

[0054] Thus, the highly resilient memory foam supports airbag 1, allowing expansion element 2 to return to its original shape after each expansion, effectively ensuring the inflatable pillow's self-shaping. Furthermore, the highly resilient foam, combined with the support of airbag 1, facilitates adjustment based on the body's contact with the inflatable pillow, improving the pillow's shape adaptability and, consequently, enhancing the user's comfort against the pillow.

[0055] Regarding the structure of the expansion member 2, in one embodiment of the present application, please refer to Figure 4 and Figure 5 The expansion member 2 is provided with a plurality of through slots 21 , and the plurality of through slots 21 all pass through the expansion member 2 .

[0056] In this embodiment, these through grooves 21 are evenly distributed throughout the expansion member 2, facilitating uniform coverage of the entire expansion member 2. The function of the expansion member 2 is to relieve internal pressure and air, allowing the expansion member 2 to actively expand and return to its original state from a compressed state, effectively reducing the expansion inertia of the expansion member 2, thereby increasing the expansion and recovery speed of the expansion member 2, shortening the initial operation time, and facilitating use.

[0057] In one embodiment of the present application, see Figure 5 , each through groove 21 on the expansion member 2 extends parallel to the same direction.

[0058] On the one hand, this helps the through slots 21 on the expansion element 2 to release pressure and air in the same direction, actively expanding and restoring the original shape. On the other hand, it helps increase the compression range of the expansion element 2, allowing the user to compress and roll up the inflatable pillow for storage, thereby minimizing the volume of the inflatable pillow.

[0059] Based on the above, in another embodiment of the present application, please refer to Figure 6The expansion member 2 is further provided with an elastic member 22 . The elastic member 22 is arranged in the through groove 21 and extends along the length direction of the through groove 21 .

[0060] In this embodiment, the elastic member 22 can preferably be a spring. Each through-slot 21 is provided with a spring. The spring's elastic force drives the expandable member 2 to actively expand and return to its original shape, effectively enhancing the active expansion of the expandable member 2. Furthermore, when the expandable member 2 is compressed and rolled up for storage, the springs can also adaptively deform, ensuring that the entire inflatable pillow can be minimized in size.

[0061] For the specific structure of the air valve 3, please refer to Figure 7 and Figure 8 The air valve 3 includes a valve body 31 and a valve cover 32. The valve body 31 is arranged on the mounting hole of the airbag 1. At least a portion of the valve cover 32 is movably connected to the valve body 31 and can be opened and closed on the valve port of the valve body 31.

[0062] In this embodiment, the mounting hole is opened on the airbag 1, and the valve body 31 is installed on the mounting hole of the airbag 1. The valve body 31 can also be preferably connected to the airbag 1 as a whole, so that the valve port in the valve body 31 is connected to the interior and the outside of the airbag 1 respectively.

[0063] Among them, one end of the valve cover 32 is movably connected to the edge of the valve body 31. Specifically, it is preferred to adopt a method of setting a rotating shaft or a folding part to enable a movable connection between the valve cover 32 and the valve body 31, so that the valve cover 32 can be rotated to open and close on the valve body 31, thereby opening and closing the valve port on the valve body 31, allowing the airbag 1 to discharge pressure.

[0064] In actual applications, only using the flip cover structure of the valve cover 32 and the valve body 31 to open and close the valve port is not conducive to accurately controlling the exhaust or intake of the airbag 1, resulting in reduced accuracy in adjusting the shape of the inflatable pillow and difficulty in fine-tuning.

[0065] Here, for the structure on the valve body 31, in one embodiment of the present application, please refer to Figure 8 The valve body 31 is also provided with an airtight switch 33, which is used to open and close the valve port on the valve body 31. This can be understood as adding a micro switch on the valve body 31 to quickly control the opening and closing of the valve port. In this embodiment, the airtight switch 33 can preferably adopt a single-click pressing method to realize the opening and closing operation of the valve port, such as pressing the valve port once to open the valve port and pressing the valve port again to close the valve port, thereby realizing rapid opening and closing of the valve port. This is conducive to the rapid suction and release operation of the internal air pressure of the inflatable pillow, thereby improving the flexibility of fine-tuning the inflatable pillow.

[0066] In actual operation, while the body is against the inflatable pillow, the airtight switch 33 is opened, and the body's natural pressure against the inflatable pillow causes the airbag 1 to inhale, thereby causing the expansion element 2 to contract and lower the height. Alternatively, after opening the airtight switch 33 and reducing the body's pressure against the inflatable pillow, the airbag 1 is deflated, allowing the expansion element 2 to naturally inflate, thereby inflating the airbag 1 and increasing the height. During the adjustment process, when the adjustment is appropriate, the airtight switch 33 can be quickly pressed to close the valve and lock the adjusted height.

[0067] In this way, the airtight switch 33 on the air valve 3 is used to open the valve port, allowing the airbag 1 to exhaust or inhale, quickly fine-tune the shape of the inflatable pillow, thereby increasing the flexibility of fine-tuning the inflatable pillow and improving the health care effect.

[0068] In another embodiment of the present application, see Figure 8 The valve cover 32 is further provided with a convex ring 321 , which extends toward the valve body 31 .

[0069] When the valve cover 32 is covered on the valve body 31 , a convex ring 321 on the valve cover 32 can surround the outer circumference of the airtight switch 33 , thereby improving the sealing effect.

[0070] In one embodiment of the present application, see Figure 7 The air valve 3 is also provided with a sealing ring 34, which is arranged on the outer periphery of the valve body 31 and is used to seal the gap between the valve body 31 and the edge of the mounting hole of the airbag 1, effectively ensuring the sealing of the mounting part of the air valve 3 on the airbag 1 to prevent air leakage.

[0071] Regarding the structure of the airbag 1, in one embodiment of the present application, please refer to Figure 1 The expansion member 2 can preferably be in the shape of a neck pillow. The expansion member 2 is filled in the interior of the airbag 1. After the expansion member 2 is inflated and recovered, the airbag 1 is supported by the expansion member 2 and assumes the shape of a neck pillow. The air valve 3 is located on the airbag 1, making it convenient for a person to manually open the valve cover 32 of the air valve 3 and operate the airtight switch 33 on the valve body 31.

[0072] In another embodiment of the present application, see Figure 9 The expansion member 2 can preferably be in the shape of a lumbar pillow. The expansion member 2 is filled inside the airbag 1. After the expansion member 2 is inflated and recovered, the airbag 1 is propped up by the expansion member 2 to assume the shape of a lumbar pillow. The air valve 3 is located on the airbag 1, making it easy for a person to manually open the valve cover 32 of the air valve 3 and operate the airtight switch 33 on the valve body 31.

[0073] In other embodiments (not shown), the expansion member 2 may also be shaped as other pillows or cushions for various parts of the human body to rest against. The expansion member 2 fills the interior of the airbag 1, and after the expansion member 2 is inflated and restored, the airbag 1 is propped up by the expansion member 2 to form a pillow or cushion of a corresponding shape. This is not specifically limited here.

[0074] Regarding the filling method of installing the expansion member 2 in the airbag 1, in one embodiment of the present application, the airbag 1 can be divided into at least two parts during the processing process, and the expansion member 2 can be first installed in one part, and then the other part of the airbag 1 is put on, and then the joints of the various parts of the airbag 1 are ultrasonically welded, so that the expansion member 2 is accommodated inside the airbag 1, effectively ensuring the sealing of the airbag 1.

[0075] To better store the inflatable pillow, in one embodiment of the present application (not shown), the inflatable pillow further includes an outer bag (not shown) for storing the rolled-up inflatable pillow. A drawstring (not shown) is provided at the opening of the outer bag for tightening the bag.

[0076] In this way, the user can roll up the inflatable pillow and put it into the coat pocket, and then use the drawstring on the coat pocket to seal the opening of the coat pocket, so that the rolled-up inflatable pillow can be stored in the coat pocket for easy carrying.

[0077] Preferably, the outer bag is also provided with a hanging buckle (not shown), which is used to hang the outer bag on a carrier, such as a travel bag, waist bag, handbag and handbag carried by the user, so as to facilitate carrying.

[0078] Among them, the hanging buckle can be set on the bag surface of the outer coat bag, and can also be preferably set on the drawstring of the outer coat bag, which is conducive to adjusting the installation position of the hanging buckle to adapt to the hangable part on the installation carrier, thereby improving the flexibility of use and facilitating user use.

[0079] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
