In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] This embodiment provides a portable heating pad, as Figure 1 and Figure 2 shown, the portable heating pad 6 includes a heating sheet 2, a mobile power supply 100 ( Figure 5 shown in), a soft core layer 3 and an outer layer 1. Among them, the heating power of the heating sheet 2 is 30W - 35W, and the area of the heating sheet 2 is 1100 cm 2 -1500 cm 2 . The mobile power supply 100 is electrically connected to the heating sheet 2 for supplying power to the heating sheet 2, and the supply voltage of the mobile power supply 100 is 12V. The soft core layer 3 is arranged on one side of the heating sheet 2. The outer layer 1 is sleeved outside the soft core layer 3 and the heating sheet 2.

[0034] The portable heating pad 6 provided in this embodiment is powered by the mobile power supply 100, enabling the user to use it while moving. Moreover, the supply voltage of the mobile power supply 100 is 12V, which is less than the safe voltage of the human body (the safe voltage of the human body is 36V). Therefore, even if electric leakage occurs, the user will not be electrocuted, and the use safety is relatively high.

[0035] The area of the heating sheet 2 of the portable heating pad 6 in this application is set to 1100 cm 2 -1500 cm 2 , making the portable heating pad 6 easy to carry; and relative to local areas such as the human waist, shoulder and leg, the portable heating pad 6 can well wrap the human body locally for hot compress (as Figure 3 and Figure 4As shown, the portable heating pad 6 is convenient to be positioned at multiple parts of the human body for use during movement. Further, in this embodiment, the shapes of the portable heating pad 6 and the heating sheet 2 are preferably set to be rectangular. The length of the heating sheet 2 is about 50 cm, and the width is about 24 cm. At one end of the outer layer 1 in the length direction, two first clamping members 400 are provided. At the other end of the outer layer in the length direction, two second clamping members 600 are correspondingly provided. The first clamping member 400 and the second clamping member 600 are clamped with each other, so that the portable heating pad 6 can be wrapped and fixed on the human body. In this embodiment, the first clamping member 400 is provided at one end close to the outer layer 1. A strap 500 is provided at the other end of the outer layer 1. The second clamping member 600 is provided on the strap 500, and the position of the second clamping member 600 on the strap 500 is adjustable. The structure of the second clamping member 600 and its adjustable structure with the strap 500 are prior arts, which are commonly seen on objects such as backpack straps and safety buckles, and will not be elaborated here too much. By adjusting the position of the second clamping member 600, the portable heating pad 6 is convenient for people with different body shapes to use.

[0036] In addition, by respectively providing the first clamping member 400 and the strap 500 at both ends of the portable heating pad 6 in the length direction, and setting the first clamping member 400 at one end close to the outer layer 1, and setting the second clamping member 600 on the strap 500 and its position adjustable, the advantage of such setting is that the length of the strap 500 can be increased, so that the portable heating pad 6 can be fixed on relatively wide parts such as the waist and abdomen, and can also be fixed on relatively narrow parts such as the legs and arms. Specifically, as Figure 3 shown, when in actual use and it is necessary to bind it to the calf of the user for hot compress, the end of the portable heating pad 6 close to the strap 500 can be pressed and fixed on the leg (not shown in the figure), and then the portable heating pad 6 is wound around the leg. Since the thickness of the human leg is different, the heating pad may overlap to form multiple layers during winding. At this time, the end of the portable heating pad 6 close to the strap 500 serves as the winding starting end 4 and is located in the inner layer, and the end of the portable heating pad 6 close to the first clamping member 400 serves as the winding ending end 5 and is located in the outermost layer. When fixing, the user only needs to press the winding ending end 5 with one hand, and pull the strap 500 out from the side of the portable heating pad 6 with the other hand. Because the length of the strap 500 is long, it can be wound around the outer surface of the portable heating pad 6 for several circles, so as to fix the winding ending end 5. Finally, the second clamping member 600 is moved along the strap 500 to the position of the winding ending end 5 to be connected with the first clamping member 400, so as to achieve the purpose of positioning the portable heating pad 6 on the leg, and the fixing process is convenient and fast. It is preferably set that the strap 500 is an elastic band, so that the length of the strap 500 can be further increased during winding, and due to the contraction force of the strap 500, the strap 500 can be more firmly wound around the surface of the portable heating pad 6 and the portable heating pad 6 can be more tightly pressed on the human body, improving the firmness.

[0037] When fixed on the waist and abdomen (not shown in the figure), the length direction of the portable heating pad 6 is wound around the human waist and abdomen. Since the waist circumference of a person is basically above 70 cm, the portable heating pad 6 can be well tied to the waist through the first clamping member 400, the strap 500 and the second clamping member 600. As Figure 4 shown, when applying hot compress to the shoulder, the portable heating pad 6 can cover the shoulder. At this time, one end of the portable heating pad 6 close to the first clamping member 400 and one end close to the strap 500 are respectively located on the front and back sides of the human body. One of the first clamping members 400 and the second clamping member 600 can be directly connected through the armpit, and the other second clamping member 600 passes through the other armpit through the strap 500 and then winds around to the side close to the first clamping member 400, so as to be connected to the other first clamping member 400, thereby forming a "diagonal shoulder strap" shape to firmly fix the portable heating pad 6 on the shoulder.

[0038] Furthermore, it is preferably set that the two first clamping members 400 and the two second clamping members 600 are arranged close to the two ends of the width direction of the portable heating pad 6. As Figure 3 shown, this is convenient for the connection between the first clamping member 400 and the second clamping member 600 when the portable heating pad 6 is wound around the leg or arm; as Figure 4 shown, it is also convenient to prevent the portable heating pad 6 from curling when the portable heating pad 6 is fixed on the shoulder and the waist and abdomen.

[0039] Furthermore, it is preferably set that the heating power of the heating sheet 2 is 30W - 35W, which can enable the portable heating pad 6 to quickly heat up to 60°C - 70°C. The heating-up speed is fast, and the temperature can be maintained at a relatively comfortable temperature, improving the user's satisfaction. It should be noted that the R & D personnel used a power supply voltage of 5V - 36V, and a heating sheet 2 with a heating power of 24W - 40W and an area of about 1200 cm 2 for a large number of tests. Among the large number of test data obtained, it was found that when the power supply voltage was 12V and the heating power of the heating sheet 2 was 33W, the heating sheet 2 could quickly heat up to 60°C, and the portable heating pad 6 could mostly maintain within a comfortable temperature range within 2 hours. Therefore, as a preferred technical solution, the heating power of the heating sheet 2 is 33W, and the specification of the heating sheet 2 is 1200 cm 2 The length of the heating wire 21 of the above-tested heating sheet 2 is within the range of 3000 - 4000 mm.

[0040] Furthermore, the capacity of the mobile power supply 100 can be greater than or equal to 55Wh. With such a setting, the portable heating pad 6 can maintain a hot compress state for about 2 hours, and the battery life is relatively long.

[0041] In this embodiment, the heating sheet 2 includes two layers of flame-retardant layers and heating wires 21 arranged between the two layers of flame-retardant layers. An insulating layer (not shown in the figure) is also provided between the flame-retardant layer and the heating wires 21. By providing the insulating layer, the risk of electric leakage can be further reduced. In addition, the setting of the flame-retardant layer can reduce the risk of fire. Optionally, the material of the flame-retardant layer can be flame-retardant needle-punched cotton, and the insulating layer can be set as an insulating coating attached to the flame-retardant layer or an additional insulating component. As Figure 2 shown, in this embodiment, the heating sheet 2 is disposed on the soft core layer 3, and only one side of the heating sheet 2 is provided with the soft core layer 3, and the other side is directly in contact with the outer layer 1, which not only improves the softness of the portable heating pad 6 but also ensures the heating efficiency of the portable heating pad 6.

[0042] Further, continue to refer to Figure 5 , an openable and closable pocket 200 is provided on the outer layer 1. The mobile power supply 100 is electrically connected to the heating sheet 2 through a charging cable 300, and the charging cable 300 and the mobile power supply 100 can be stored in the pocket 200. And, the charging cable 300 is lengthened. When applying hot compress to the shoulder, the mobile power supply 100 can also be taken out of the pocket 200 and put into the trouser pocket to reduce the weight of the portable heating pad 6, thereby improving the comfort.

[0043] Further, the portable heating pad 6 further includes a power adapter and a power cord (not shown in the figure). When there is a long-term use requirement, the power adapter can be electrically connected to the heating sheet 2, and then the power cord can be inserted into the household electricity for power supply, without worrying about the battery life problem. And the mobile power supply 100 can also be charged with household electricity through the power adapter.

[0044] It can be understood that when charging the mobile power supply 100 through the power cord and the power adapter, a conversion cable may be needed to connect the adapter and the mobile power supply 100.

[0045] Further, in a possible embodiment, the portable heating pad 6 further includes a three-gear temperature control and timing switch (not shown in the figure), and the three-gear temperature control and timing switch is electrically connected to the heating sheet 2. Through the three-gear temperature control and timing switch, on the one hand, the user can select a suitable temperature according to the use requirement; on the other hand, the user can select the heating time to avoid scalding the user due to long-term heating or causing a safety accident due to the user forgetting to turn off the machine. Optionally, the three gears of temperature can be set to 45°C, 55°C, and 65°C. Of course, in other embodiments, the three gears of temperature can also be set to other values, which can be set according to the use requirement without specific limitation.

[0046] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
