[0034] Embodiment

[0035] This embodiment provides a heating hand and foot ring, which includes a housing 1, a heat conduction plate 3 disposed outside the housing 1, and a heating sheet 2 disposed on the heat conduction plate 3. The heat conduction plate 3 is located below the housing 1, and the heating sheet 2 is disposed between the heat conduction plate 3 and the housing 1.

[0036] The specific improvement is as follows: As Figure 1 and Figure 5 shown, compared with the prior art, the heating sheet 2 is disposed on the heat conduction plate 3, the heat conduction plate 3 is disposed on the side of the housing 1 in contact with the skin below, the heating sheet 2 is disposed between the heat conduction plate 3 and the housing 1, and there is no need to connect the heating sheet 2 and the heat conduction plate 3 with a wire. Heat is conducted through direct contact, so that it can effectively avoid the problems in the prior art that during the continuous wearing and taking off of the fixing band 6, the wire will move due to the movement of the wire and the electric heating element, and the electric heating element will be bent when the fixing band 6 is bent, resulting in wire de-soldering and poor product contact during the continuous bending process of the wire and the electric heating element.

[0037] Based on the above embodiment: The housing 1 includes a base plate 11 and a cover plate 12 located above the base plate 11. An accommodation cavity 13 is formed between the base plate 11 and the cover plate 12. A power supply device for supplying power to the heating sheet 2 is disposed in the accommodation cavity, and the heat conduction plate 3 is located on the side of the base plate 11 facing away from the cover plate 12.

[0038] The specific improvement is as follows: As Figure 1 and Figure 2 shown, the housing 1 includes a base plate 11 and a cover plate 12 located above the base plate 11. There is an accommodation cavity 13 between the base plate 11 and the cover plate 12. The power supply device 4 is disposed in the accommodation cavity 13. The power supply device 4 supplies power to the heating sheet 2 through a wire. The heating sheet 2 generates heat and conducts the heat to the heat conduction plate 3 through direct contact with the heat conduction plate 3 (no wire is required for transmission between the two), so that the heat is conducted to the human skin through the heat conduction plate 3.

[0039] Based on the above embodiment: The power supply device 4 includes a circuit board 41 and a storage battery 42 for supplying power to the circuit board 41. The circuit board 41 is connected to the heating sheet 2 by a wire, the storage battery 42 is connected to the circuit board 41 by a wire. The base plate 11 includes an upper bottom surface 111 and a lower bottom surface 112. A placement groove 14 for accommodating the heating sheet 2 is provided at the lower bottom surface 112, and a heat insulation cotton 15 is provided between the upper bottom surface 111 and the storage battery 42.

[0040] The specific improvement is as follows: As Figures 2 - 4As shown in the figure, the power supply device 4 includes a circuit board 41 and a storage battery 42 that powers the circuit board 41. The storage battery 42 supplies power to the circuit board 41, and the circuit board 41 distributes the circuit. A wire is used to connect the circuit board 41 and the heating sheet 2 to form energy transfer. The substrate 11 is divided into an upper bottom surface 111 and a lower bottom surface 112. A placement groove 14 is provided on the lower bottom surface 112. Through the setting of the placement groove 14, the heating sheet 2 can be accommodated. Above the upper bottom surface 111, a heat insulation cotton 15 is also provided to isolate the heat conduction of the heating sheet to the storage battery 42. There is a gap between the heating sheet 2 and the lower bottom surface 112 of the substrate 11 to prevent direct contact between the heating sheet 2 and the storage battery 42, thereby avoiding the direct conduction of the heat of the heating sheet 2 to the storage battery 42 (the heat conducted from the heating sheet 2 to the storage battery 42 cannot act on the human body and may damage the storage battery 42. Through the setting of this gap, the heat will float in the gap in the form of gas. When the heat is conducted to the storage battery 42, a small part of the temperature drop has occurred, so that the temperature of the heat reaching the housing 1 will be lower than the temperature of the heating sheet 2 itself, thereby playing a protective role for the storage battery 42), avoiding the direct conduction of heat to the storage battery 42 and reducing the damage to the storage battery. Through the settings of the heat insulation cotton 15 and the gap between the substrate 11 and the heating sheet 2, the heat conduction of the heating sheet to the storage battery 42 can be blocked, thereby damaging the life of the storage battery 42.

[0041] Based on the above embodiment: The power supply device 4 further includes a charging interface 43. The charging interface 43 is located on the circuit board 41. The circuit board 41 is located on the side of the storage battery 42. A micro switch is provided on the circuit board 41, and a pressing key 44 is provided on the cover plate 12. The pressing key 44 is linked with the micro switch.

[0042] The above specific improvement is that the power supply device 4 further includes a charging interface 43. Through the setting of the charging interface 43, current can be supplied to the circuit board 41 to complete the charging process. A micro switch is provided on the circuit board 41. When in use, the user can press the pressing key 44, and then the pressing key 44 is pressed to turn the micro switch on or off. The pressing key 44 can be provided on the cover plate 12 or on the side of the housing 1. Those skilled in the art can select the setting position of the pressing key 44 according to the circuit layout.

[0043] Based on the above embodiment: The substrate 11 is provided with an avoidance groove 5 for the wire to pass through. A temperature controller 51 is provided in the avoidance groove 5. The temperature controller 51 is located on the heating sheet and is connected to the circuit board 41.

[0044] The above-mentioned specific improvements are as follows: by setting the avoidance groove 5, space can be freed up for placing the wire, so that the wire can pass through the shell 1 and connect with the heating plate 2 under the shell 1. By setting the temperature controller 51, when the current in the circuit is too large, the temperature controller 51 can monitor the temperature increase and protect the circuit by reducing the resistance value to prevent the circuit from being damaged by overheating.

[0045] On the basis of the above embodiment: the lower bottom surface 112 is provided with an embedding groove 16 for embedding the heat conducting plate 3, the embedding groove 16 is connected with the placement groove 14, the heat conducting plate 3 is made of metal material, and a heat insulating layer 17 is attached to the side of the heat conducting plate 3 that contacts the arm.

[0046] The above specific improvements are: Figure 5 and Figure 9 As shown, the placement groove 14 accommodates the heating plate 2, and the embedding groove 16 fixes the thermal conduction plate 3. Through the setting of the embedding groove 16, the thermal conduction plate 3 can be embedded in the embedding groove 16, thereby increasing the wearer's comfort experience. The thermal insulation layer 17 is made of fluff material, which is used to prevent the arm from directly contacting the thermal conduction plate 3 and causing arm burns. In addition, by covering the thermal insulation layer 17 on the thermal conduction plate 3, it is possible to prevent the heat on the thermal conduction plate 3 from being lost too quickly, thereby achieving a better thermal insulation effect. When installing the thermal conduction plate 3, it is only necessary to install the thermal conduction plate 3 into the embedding groove, and then apply glue at the connection between the embedding groove and the thermal conduction plate 3, so that the two can be quickly connected together and the position of the thermal conduction plate 3 can be fixed.

[0047] On the basis of the above embodiment: a fixing belt 6 is connected to the side of the shell 1 , and a connecting ear 7 for the fixing belt 6 to pass through is provided on the side of the upper bottom surface 111 and / or the lower bottom surface 112 .

[0048] On the basis of the above embodiment: the connecting ear 7 is arranged on the base plate 11 or the cover plate 12, and the connecting ear 7 includes a first connecting portion 71 located on one side of the base plate 11 or the cover plate 12 and a second connecting portion 72 located on the other side, the first connecting portion 71 is fixedly connected to one end of the fixing belt 6, and the second connecting portion 72 is provided with a through groove 73 for the other end of the fixing belt 6 to pass through.

[0049] On the basis of the above embodiment: a fitting mechanism 8 is provided on the fixing belt 6, and the fitting mechanism 8 includes a Velcro A surface and a Velcro B surface. When the fixing belt 6 is wrapped around the arm, the Velcro A surface fits with the Velcro B surface, and a plurality of array-arranged veneers are formed on the Velcro A surface.

[0050] The specific improvements are as follows: The bracelet can be placed around the ankle, tied to the foot, or worn on the hand with the fixing strap 6. To connect the housing 1 and the fixing strap 6, connection ears 7 are provided on both sides of the upper bottom surface 111 of the housing 1. One end of the fixing strap 6 is fixed to the first connection part 71, and the other end passes from below the second connection part 72 to above the second connection part 72, and then the hook-and-loop fastener A side and the hook-and-loop fastener B side provided on the fixing strap 6 are pasted together.

[0051] Based on the above embodiment: A stop block 9 for preventing the fixing strap 6 from slipping out of the slot 73 is provided at the end of the fixing strap 6.

[0052] The specific improvements are as follows: As Figures 6 - 8 shown, the heating ring (for the housing 1 and the parts inside the housing 1) can be equipped with a bracelet and an ankle strap, or can be used alone and stuffed into a sock (the housing of the heating ring stuffed into the sock does not have the connection ears 7). When stuffed into the sock, the heating ring does not need to be equipped with a bracelet and an ankle strap. When the heating ring is used in combination with the ankle strap, the fixing strap 6 can be passed through the second connection part 72, the hook-and-loop fastener A side and the hook-and-loop fastener B side are torn apart, the space is adjusted to a suitable size, and then the hook-and-loop fastener A side and the hook-and-loop fastener B side are pasted together. When worn on the hand, there is an additional stop block 9 on the fixing strap 6. Through the setting of the stop block 9, it can be avoided that the fixing strap 6 is separated from the second connection part 72. After the fixing strap 6 passes through the first connection part 71 and the second connection part 72, a space for a hand to reach in will be formed. When adjusting the size of the space, (since when worn on the hand, only one hand can operate, so it is necessary to avoid the fixing strap slipping out of the second connection part 72), only the hook-and-loop fastener A side and the hook-and-loop fastener B side need to be torn apart, the space is adjusted to a suitable size, and then the hook-and-loop fastener A side and the hook-and-loop fastener B side are pasted together.

[0053] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
