Description

Technical Field

[0001] The invention relates to the field of bedding, in particular to a pillow. Background Art

[0002] Existing pillows include a pillow body with a heating structure. When powered, the heating structure generates heat and applies a warm compress to the user's neck and shoulders, promoting blood circulation and relaxing the neck and shoulders. The heating structure is typically located on the top surface of the pillow body and comprises a sheet-like substrate and heating wires disposed on the substrate. This type of pillow has the following drawbacks: The dispersed placement of the heating wires results in uneven temperatures across the heating structure, making it prone to localized overheating. Furthermore, because the substrate is located on the top surface of the pillow body, the user experiences a foreign body sensation caused by the substrate being squeezed, compromising comfort. Summary of the Invention

[0003] In order to address the shortcomings of the existing technology, the present invention provides a pillow with a flexible heating sheet. The flexible heating sheet is arranged on the top surface of the pillow body. The flexible heating sheet can utilize its own deformation to match and fit the user's surface, reducing the foreign body sensation, and can also ensure that the temperature of each area of ​​the flexible heating sheet is balanced, thereby improving the user experience.

[0004] The present invention is achieved through the following method: a pillow with a flexible heating sheet, comprising a pillow body, a groove provided in the middle of the front edge of the pillow body, a flexible heating sheet positioned within the groove, the flexible heating sheet matingly fitting with the bottom wall of the groove and smoothly adjoining the front edge of the pillow body, so that the flexible heating sheet deforms synchronously with the front edge of the pillow body and eliminates the sensation of a foreign body. The flexible heating sheet is disposed on the top surface of the pillow body, which not only utilizes its own deformation to mate with the pillow body surface, thereby reducing the foreign body sensation when the user lies down, but also ensures a uniform temperature across all areas of the flexible heating sheet, enhancing the user experience.

[0005] Preferably, the bezel is formed on the front wall and top wall of the pillow body at the middle of the front edge, and the contour of the flexible heating sheet matches the contour of the bezel opening to eliminate any gap between the periphery of the flexible heating sheet and the periphery of the bezel. The bezel provides installation space for the flexible heating sheet. The bezel is formed on the front wall and top wall of the pillow body to position the flexible heating sheet, ensuring that the flexible heating sheet can simultaneously contact the user's shoulders and neck, providing heat to the user's shoulders and neck, promoting blood circulation, and relaxing the shoulders and neck.

[0006] Preferably, the embedding groove depth matches the thickness of the flexible heating sheet, and the embedding groove depth is A, A≤2mm, which not only ensures that the flexible heating sheet can be effectively hidden and effectively reduces the foreign body sensation, but also plays a positioning role for the flexible heating sheet to prevent the flexible heating sheet from being offset due to force extrusion.

[0007] Preferably, the width of the embedding groove along the horizontal direction of the pillow body is B, 220mm≤B≤300mm, and the length of the embedding groove along the longitudinal direction of the pillow body is C, 80mm≤C≤150mm. This not only expands the coverage area of ​​the flexible heating sheet by increasing the size, thereby ensuring that the user's shoulders and neck can be effectively covered and heated, but also reduces costs by limiting the size of the flexible heating sheet.

[0008] Preferably, the pillow includes a flannel layer that completely covers the flexible heating sheet. The middle portion of the flannel layer covers the flexible heating sheet, and the periphery is adhesively bonded to the pillow body. The flannel layer is relatively soft and can utilize its own deformation to eliminate the gap between the flexible heating sheet and the periphery of the inlay slot, reducing the foreign body sensation, improving the comfort of contact with the user's surface, and protecting the flexible heating sheet. The flannel layer is adhesively bonded to the pillow body and covers the flexible heating sheet, preventing the flannel layer from being deflected by force.

[0009] Preferably, the flexible heating sheet is a graphene fabric woven with graphene filaments. Graphene fabric is safe, reliable, and highly efficient in heating. It effectively saves energy and, through its weaving, ensures uniform temperature across the flexible heating sheet, effectively enhancing its flexibility and reducing the sensation of a foreign body.

[0010] Preferably, a vertical through-hole is provided at the bottom of the edge of the slot, and a wire carrying a controller is provided on the flexible heating sheet. The wire passes through the through-hole from top to bottom and is connected to a power source. The through-hole is provided at the bottom of the slot, and the flexible heating sheet covers the through-hole, facilitating the wire's passage through and connection to the controller, thereby facilitating control of the flexible heating sheet's operating status.

[0011] Preferably, the conductors are segmented, including a front conductor connected to the flexible heating sheet and a rear conductor connected in series with the controller. The front conductor passes through a perforation and connects to the rear conductor beneath the pillow. The front conductor connects to the flexible heating sheet and passes through a perforation, while the rear conductor is connected in series with the controller and connected to the front conductor. This eliminates the need for the controller to pass through the perforation, effectively improving assembly and disassembly convenience and maintenance efficiency while also reducing the perforation size requirement, thereby minimizing the foreign body sensation.

[0012] Preferably, one end of the rear line is connected to the front line through a type-c interface, and the other end is connected to an external power supply, which not only facilitates the plug-in connection of the rear line and the front line, but also ensures a reliable connection between the two, improves the reliability of data and power transmission, and prevents the front line and the rear line from being detached due to pulling.

[0013] Preferably, the pillow is wrapped in a pillowcase with a through hole for the wires to pass through. The pillowcase not only protects the pillow, facilitates removal and cleaning, but also serves as a decorative element, allowing replacement of pillowcases with different styles as needed. The through hole in the pillowcase allows the wire ends to be exposed and connected to an external power source, ensuring continuous and stable operation of the flexible heating element.

[0014] The beneficial effects of the present invention are as follows: a flexible heating sheet is arranged on the top surface of the pillow body, which can not only utilize the deformation of the flexible heating sheet itself to match and fit with the surface of the pillow body, thereby reducing the foreign body sensation when the user lies down, but also ensure that the temperature of each area of ​​the flexible heating sheet is balanced, thereby improving the user experience.

[0019] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0020] like Figure 1 The pillow shown includes a pillow body 1, with a groove 2 provided in the middle of the front edge of the pillow body 1. A flexible heating sheet 3 is placed in the groove 2. The flexible heating sheet 3 matches the bottom wall of the groove 2 and smoothly connects with the front edge of the pillow body 1, so that the flexible heating sheet 3 deforms synchronously with the front edge of the pillow body 1 and eliminates the foreign body sensation. The flexible heating sheet 3 is arranged on the top surface of the pillow body 1. This allows the flexible heating sheet 3 to deform and match the surface of the pillow body 1, thereby reducing the foreign body sensation when the user lies down, and also ensures that the temperature of each area of ​​the flexible heating sheet 3 is balanced, improving the user experience.

[0021] In actual operation, the embedding groove 2 is opened on the front wall and top wall in the middle of the front edge of the pillow body 1. The contour of the flexible heating sheet 3 matches the contour of the notch of the embedding groove 2 to eliminate the gap between the periphery of the flexible heating sheet 3 and the periphery of the embedding groove 2. During installation, first, the end of the front wire 6 is passed from top to bottom through the perforation 5 and exposed on the bottom surface of the pillow body 1; then, the flexible heating sheet 3 is spread onto the bottom wall of the embedding groove 2, so that the bottom surface of the flexible heating sheet 3 is in contact with the bottom wall of the embedding groove 2 and the periphery of the flexible heating sheet 3 is in contact with the side walls of the embedding groove 2; then, the flannel layer 4 is covered on the front wall and top wall of the pillow body 1 and adhered and fixed so that the notch of the embedding groove 2 is completely covered by the flannel layer 4; then, the pillowcase is placed on the pillow body 1, and the end of the front wire 6 passes through the through hole and is exposed on the pillowcase; finally, the end of the front wire 6 is connected to the end of the rear wire 7.

[0022] After installation, Figure 2 As shown, the controller 8 is exposed on the pillowcase for easy operation by the user. When in use, the wire is connected to an external power source, and the user controls the flexible heating sheet 3 through the controller 8. The flexible heating sheet 3 has a multi-level temperature adjustment function to meet the differentiated needs of users.

[0023] In actual operation, the depth of the bezel 2 matches the thickness of the flexible heating sheet 3. The depth of the bezel 2 is A, where A is ≤ 2 mm. The depth of the bezel 2 is the same as the thickness of the flexible heating sheet 3, ensuring that the top surface of the flexible heating sheet 3 is smoothly connected to the surface of the pillow body 1, thereby reducing the foreign body sensation by eliminating the height difference.

[0024] In actual operation, the length and width of the flexible heating sheet 3 correspond to the length and width of the embedding groove 2, ensuring that the flexible heating sheet 3 can completely fill the embedding groove 2. The sidewalls of the embedding groove 2 also restrict the flexible heating sheet 3 from leaving the embedding groove 2, preventing the flexible heating sheet 3 from deflecting due to force. Specifically, the width of the embedding groove 2 along the horizontal direction of the pillow body 1 is B, 220mm≤B≤300mm, and the length of the embedding groove 2 along the longitudinal direction of the pillow body 1 is C, 80mm≤C≤150mm. Parameters B and C can be set according to the size of the configured flexible heating sheet 3. The preferred solution is B = 260mm and C = 110mm, both of which should be considered specific embodiments of the present invention.

[0025] In actual operation, the pillow includes a flannel layer 4 that completely covers the flexible heating sheet 3. The middle portion of the flannel layer 4 covers the flexible heating sheet 3, and the periphery is adhered and fixed to the pillow body 1. The length and width of the flannel layer 4 are larger than the length and width of the notch of the embedding groove 2. This ensures that the flannel layer 4 completely covers the notch and also increases the width of the adhesion area between the periphery of the flannel layer 4 and the periphery of the notch, thereby improving adhesion reliability.

[0026] In practice, the flexible heating sheet 3 is a graphene fabric woven with graphene filaments. By replacing traditional heating filaments with carbon fiber, the graphene material is presented as graphene filaments and embedded into the flexible fabric through weaving, creating a flexible heating sheet 3 with heating function. The touch and material properties are closer to those of ordinary fabric, improving overall comfort.

[0027] In actual operation, the bottom edge of the embedding groove 2 is provided with a vertical through hole 5 (such as Figure 3 As shown, the flexible heating sheet 3 is provided with a wire carrying a controller 8, which passes through a perforation 5 from top to bottom and is connected to a power source. The perforation 5 is located below the connection between the front wire 6 and the flexible heating sheet 3, ensuring that the front wire 6 can pass through the perforation 5 from top to bottom, effectively shortening the length of the front wire 6 within the embedding groove 2, thereby reducing the foreign body sensation.

[0028] In actual operation, the wire is a segmented structure, including a front wire 6 connected to the flexible heating sheet 3 and a rear wire 7 connected in series with the controller 8. The front wire 6 passes through the perforation 5 and is connected to the rear wire 7 under the pillow body 1. One end of the front wire 6 is connected to the flexible heating sheet 3, and no electrical components are set on it. The diameter of each section of the front wire 6 is smaller than the diameter of the perforation 5, ensuring that the front wire 6 can completely pass through the perforation 5 and the through hole to prevent jamming. The connecting end of the front wire 6 passes through the perforation 5 and the through hole in turn and is exposed to the pillowcase and connected to the rear wire 7 through the type-c interface 9. The rear wire 7 is connected in series with the controller 8 and is connected to the external power supply to ensure that the flexible heating sheet 3 can obtain the control signal and the power required for operation.

[0029] In actual operation, the pillow body 1 is wrapped in a pillowcase with a through-hole for the wires to pass through. The pillowcase has an openable and closable opening, through which the pillow body 1 is inserted, facilitating assembly and disassembly. The through-hole is preferably located on the side edge of the pillowcase, providing shielding and protection for the wires beneath the pillow body 1 while also facilitating exposure of the wires for connection to an external power source.
