[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] First embodiment:

[0026] A breathable heating pad, such as Figure 1 and Figure 2 As shown, the pad body 1 includes a pad body 1 on which a plurality of air permeable channels 2 are arranged. The air permeable channels 2 penetrate the upper and lower end surfaces of the pad body 1 . A heating element 3 is arranged inside the pad body 1 .

[0027] The pad body 1 includes an upper piece 101 and a lower piece 102. The edges of the upper piece 101 and the lower piece 102 are connected by high-frequency welding or heat welding to form a sealed air cavity. An air nozzle is provided on the surface of the pad body 1. Air is inflated into the air cavity through the air nozzle to shape the pad body 1. After the inflation is completed, the air nozzle can be closed to seal the air cavity.

[0028] The upper sheet 101 and the lower sheet 102 are both provided with a plurality of through holes, and the through holes of the upper sheet 101 and the lower sheet 102 are aligned with each other. A plurality of tubular drawstrings 103 corresponding to the through holes are provided between the upper sheet 101 and the lower sheet 102, and the upper and lower ends of the drawstrings 103 are respectively connected to the through holes of the upper sheet 101 and the lower sheet 102, thereby forming a breathable channel 2, so that the upper and lower ends of the pad body 1 can pass through after inflation and molding, and the upper and lower ends of the drawstrings 103 are fixed by high-frequency welding or hot welding.

[0029] The heating element 3 is specifically a metal heating plate, which includes a plurality of rectangular thin metal heating plates, which are uniformly controlled by a switch. The metal heating plates are fixed to the lower plate 102 by glue or tape, and in this embodiment, the air permeable channels 2 are arranged in a plurality of columns, and the metal heating plates are clamped between adjacent columns. The two sides of the metal heating plates are fitted with the air permeable channels 2 to position the metal heating plates so that they will not shift, thereby further improving the stability of the metal heating plates.

[0030] A charging interface is provided on the surface of the pad body 1, and the charging interface is connected to the wire of the heating element 3 to charge the heating element 3. The charging interface can be a Type-C or USB interface.

[0031] In this embodiment, the cushion body 1 is rectangular and can be used as a seat cushion. In other embodiments, the cushion body 1 can be set in shape and size according to needs.

[0032] Second embodiment:

[0033] A heating foot pad, such as Figure 3 As shown, it includes a foot pad cover 4, in which the breathable heating pad described in the first embodiment is arranged. The difference from the first embodiment is that the shape and size of the pad body 1 are different. In this embodiment, the shape of the pad body 1 is the shape of a foot sole, which fits the user's foot better.

[0034] An opening is provided at one end of the foot pad cover 4, and the opening is larger than the thickness of the breathable heating pad. The opening is used for the user to insert the foot into the foot pad cover 4. When the user inserts the foot into the foot pad cover 4, the sole of the foot fits against the breathable heating pad, and the foot pad cover 4 covers the breathable heating pad and the foot to warm the foot. The breathable heating pad can be fixed in the foot pad cover 4 by glue and tape, or it can be directly installed in the foot pad cover 4 and set separately from the foot pad cover 4.

[0035] The remaining parts not described are the same as those in the first embodiment and will not be described in detail.

[0036] Third embodiment:

[0037] A heating belt, such as Figure 4 As shown, it includes a strap 5, on which at least one breathable heating pad described in the first embodiment is arranged. The user fixes the belt on the body through the strap 5, so that the breathable heating pad fits the body.

[0038] In this embodiment, two breathable heating pads are specifically provided on the bandage 5, and the two breathable heating pads are parallel to each other. The belt is ring-shaped as a whole. When the user fixes the bandage 5 on the body, the two breathable heating pads fit against the user's abdomen and lower back respectively, which can warm the abdomen and waist at the same time.

[0039] The connection between the strap 5 and the breathable heating pad is fixed by a heat sealing sheet. The strap 5 on one side is directly connected between the two breathable heating pads, and the strap 5 on the other side is separated for wearing. The two ends of the strap 5 are fixed by Velcro for easy wearing. The tightness can be adjusted according to the fitting position of the Velcro. In other embodiments, it can also be fixed by the direction of the male and female buckles.

[0040] The remaining parts not described are the same as those in the first embodiment and will not be described in detail.
