Description

Technical Field

[0001] This application relates to the technical field of home physiotherapy equipment, and particularly to a heating pad and a seat with the same. Background Art

[0002] With the improvement of health awareness, heating pads (such as heating seat cushions and heating lumbar supports) are widely used in home and office scenarios to relieve local cold or muscle fatigue of the human body. Some products also integrate physiotherapy functions such as moxibustion to further meet the health needs of users.

[0003] However, most existing heating pads use resistive heating sheets as the core heating components. Due to their own structural characteristics (such as the high hardness of the metal heating wire encapsulation layer), the heating sheets have poor flexibility and a relatively large thickness. When in use, the heating sheets are likely to come into direct contact with the human body or form hard protrusions inside the pad. Especially when the sitting or leaning posture changes, a strong sense of foreign body is easily generated, seriously affecting the comfort of use, and even causing discomfort due to local compression. Utility Model Content

[0004] In order to improve the comfort of the heating pad, this application provides a heating pad and a seat with the same.

[0005] In a first aspect, this application provides a heating pad, adopting the following technical solutions:

[0006] A heating pad, characterized by comprising:

[0007] A pad body, the pad body includes a first cushion layer and a second cushion layer arranged in a stacked manner, the second cushion layer is used for contacting the human body, and at least one accommodating portion is provided on one side of the first cushion layer facing the second cushion layer;

[0008] At least one flexible heating sheet, the flexible heating sheet is accommodated in the accommodating portion.

[0009] Further, the shape and size of the flexible heating sheet are adapted to the accommodating portion.

[0010] Further, there are multiple flexible heating sheets, and the distribution forms of the multiple flexible heating sheets include at least one of the following:

[0011] Two flexible heating sheets are symmetrically arranged on the pad body with respect to the longitudinal center line of the pad body, and respectively correspond to the scapular regions of the human back;

[0012] Three flexible heating sheets are arranged in a "pin" shape on the pad body, and correspond to the pressure-bearing regions of the human buttocks.

[0013] Further, it further includes a functional component, and the functional component includes:

[0014] At least one functional piece, which has an auxiliary physiotherapy function when heated;

[0015] The second pad layer has at least one mounting groove on the side facing away from the first pad layer. The mounting groove corresponds to the position of the receiving part, and the functional piece is embedded in the mounting groove.

[0016] A limiting member is provided to confine the functional piece within the mounting groove.

[0017] Furthermore, the limiting member is a baffle plate, which is detachably connected to the second pad layer via a connector, and is used to fix the functional piece in the mounting groove.

[0018] Furthermore, the connector is a hook and loop fastener, the rough side of which is fixed to the surface of the second padding layer around the opening of the mounting slot, and the hook side of which is disposed on the side of the baffle facing the second padding layer.

[0019] Furthermore, it also includes a power supply device, which is electrically connected to the flexible heating element and is used to supply power to the flexible heating element.

[0020] Furthermore, the power supply device includes a power supply line and a power interface. One end of the power supply line is connected to the flexible heating element, and the other end extends along the width direction of the pad and protrudes from the pad, and is connected to the power interface.

[0021] Secondly, this application also provides a seating device, including a seat cushion for supporting the buttocks of a human body and a backrest for the back of a human body to lean against, wherein the seat cushion and / or the backrest are equipped with the heating pad.

[0022] Furthermore, the connection method between the heating pad and the seat cushion, and between the heating pad and the backrest, can be selected independently as a fixed connection or a detachable connection.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. On the one hand, using flexible heating pads instead of traditional resistive hard pads can improve human comfort. On the other hand, by limiting and wrapping the flexible heating pads with the receiving part, the flexible heating pads are prevented from directly contacting the human body or protruding in the pad. At the same time, the second pad layer (flexible material) can further buffer the contact between the flexible heating pads and the human body, completely eliminating the hard foreign object feeling brought by traditional resistive heating pads.

[0025] 2. In the existing technology, the heating element does not have a fixed positioning structure, which makes it easy to shift during use (such as after sitting and squeezing for a long time, causing it to deviate from the target area), resulting in uneven heating; by confining the flexible heating element within the receiving part, the displacement of the flexible heating element is prevented, ensuring the stability of the heating area and solving the problem of insufficient heating accuracy.

[0026] 3. An installation groove is provided in the second padding layer corresponding to the receiving part to ensure precise alignment between the functional piece and the flexible heating piece, avoiding the problem of poor physiotherapy effect caused by the functional piece being offset from the heating area in the existing technology, and solving the defect of unreasonable position of the functional piece from the structural root.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Therefore, the detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to represent selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0035] Example 1

[0036] Reference Figure 1 This embodiment provides a heating pad, including a pad body 1, a flexible heating element 2, and a power supply device 3. The pad body 1 includes a first pad layer 11 and a second pad layer 12 stacked together, with the second pad layer 12 located above the first pad layer 11. The first pad layer 11 and the second pad layer 12 are connected along the edge by high-frequency heat sealing or sewing. The second pad layer 12 is made of skin-friendly fabric (such as fleece) and serves as the contact layer with the human body.

[0037] Reference Figure 1 and Figure 2 The first pad 11, facing the second pad 12, has a rectangular receiving portion 13 formed by molding. The flexible heating element 2 is a graphene heating element, whose shape and size are precisely adapted to the receiving portion 13. During assembly, the flexible heating element 2 is embedded into the receiving portion 13, and then the second pad 12 is covered and sealed, thereby making the flexible heating element 2 securely embedded in the receiving portion 13. Confining the flexible heating element 2 within the receiving portion 13 prevents displacement of the flexible heating element 2, ensures the stability of the heating area, and solves the problem of insufficient heating accuracy.

[0038] During use, the first pad 11 and the flexible heating element 2 have different deformation coefficients. When the first pad 11 is deformed under pressure, the flexible heating element 2 may bulge slightly due to minor deformation, causing discomfort. The second pad 12, covering the first pad 11, uses its soft material to "wrap" around the bulge, cushioning the direct pressure of the heating element on the skin through its own deformation, resulting in a uniformly soft touch. Simultaneously, as the flexible heating element 2 is an electrically conductive heating component, the second pad 12 forms a physical protective barrier, preventing direct contact between the flexible heating element 2 and the skin. Through the heat insulation effect of the second pad 12, heat is more evenly distributed to the body, reducing the risk of localized high-temperature burns.

[0039] Reference Figure 2 The power supply device 3 is electrically connected to the flexible heating element 2 to supply power to it. In this embodiment, the power supply device 3 includes a power supply line 31 and a power interface 32. One end of the power supply line 31 is connected to the flexible heating element 2, and the other end extends along the width of the pad 1 and out of the pad 1, and is connected to the power interface 32. In other embodiments, the power supply device 3 can also be a built-in battery. The built-in battery is detachably installed at the corner of the pad 1 through a fabric pouch and connected to the heating element through a wire with a control switch. This method makes the heating pad completely wireless, highly portable, and suitable for outdoor or mobile applications.

[0040] Example 2

[0041] Reference Figure 3This embodiment provides a heating pad for the back. The difference between this embodiment and Embodiment 1 is that two symmetrical receiving portions 13 are formed on the first pad layer 11, with two graphene heating elements embedded therein. The positions of these two receiving portions 13 are ergonomically designed to correspond precisely to the left and right scapular regions of the human back. The two heating elements can be controlled independently or synchronously to achieve precise heat application to the scapular region.

[0042] Example 3

[0043] Reference Figure 2 This embodiment provides a heating pad for the buttocks. The difference between this embodiment and Embodiment 1 is that three receiving portions 13 are formed on the first pad layer 11, arranged in a triangular pattern, corresponding to the left and right sides of the buttocks and the coccyx region, respectively. Three graphene heating elements are embedded in their respective receiving portions 13, achieving targeted heating of key pressure points on the buttocks.

[0044] Example 4

[0045] Reference Figure 1 and Figure 4 Based on embodiment 3, this embodiment adds a functional component 4, in which a circular mounting groove 14 is recessed on the outer surface of the second pad layer 12 (i.e. the human body contact surface) corresponding to the middle receiving part 13.

[0046] Functional component 4 includes a mugwort functional sheet 41 made of mugwort powder wrapped in non-woven fabric (in other embodiments, the functional sheet can be other items that provide auxiliary physiotherapy when heated), and a limiting member for confining the functional sheet 41 within the mounting groove 14, the functional sheet 41 being adapted to the shape of the mounting groove 14. The limiting member is a baffle 42, which is detachably connected to the second padding layer 12 via a connector. In this embodiment, the connector is a Velcro 41, the looped side of which is fixed to the surface of the second padding layer 12 outside the opening of the mounting groove 14, with the looped side of the Velcro 43 facing the baffle 42, and the hook side of the Velcro 43 fixed to the side of the baffle 42 facing the second padding layer 12. By adhering the looped and hook sides of the Velcro 43, the baffle 42 covers the functional sheet 41. In other embodiments, the connector can be at least one of a button, zipper, snap, hook and loop fastener, or other structures that enable a detachable connection.

[0047] In other embodiments, the number of functional components 4 may be equal to or less than the number of flexible heating elements 2.

[0048] In use, place the mugwort functional sheet 41 into the installation groove 14, then cover it with the baffle 42, and press to bond the hook surface and the plush surface of the magic tape 43, thereby fixing the mugwort functional sheet 41. When the heating sheet works, heat is conducted to the mugwort functional sheet 41, causing its active ingredients to volatilize, achieving the dual effects of moxibustion and hot compress. After the mugwort functional sheet 41 is used up, it can be easily replaced.

[0049] Embodiment 5

[0050] This embodiment provides a seating device, which can be a footless seat, that is, a lumbar support cushion, or other seating devices. The seating device includes a seat cushion part for supporting the human buttocks and a backrest part for the human back to lean on. The seat cushion part is equipped with the hip heating pads distributed in a "pin" shape disclosed in Embodiment 3. The backrest part is equipped with the double heating sheet back heating pads symmetrically distributed disclosed in Embodiment 2.

[0051] The connection methods between the heating pads and the seat cushion part, and between the heating pads and the backrest part are independently selected from any of the following connection methods: fixed connection (such as sewing or gluing, etc.); detachable connection (such as button connection, magic tape connection, snap connection, zipper connection, etc.).

[0052] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
