DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-Figure 5 A sofa chair cushion with a heating function includes a cloth pad component 1, the cloth pad component 1 includes an upper thermal conductive pad 101 and a lower thermal insulation pad 103, and a same heating component 2 is bonded between the upper thermal conductive pad 101 and the lower thermal insulation pad 103, an upper breathable cloth pad 102 is bonded to the upper surface of the upper thermal conductive pad 101, and the upper breathable cloth pad 102 is a cotton and linen cloth pad. The upper breathable cloth pad 102 made of cotton and linen has good air permeability, soft touch, and certain wear resistance, which improves the comfort of using the upper breathable cloth pad 102, and the design of the upper breathable cloth pad 102 improves the ventilation effect between the cushion and people, and a lower wear-resistant cloth pad 104 is bonded to the lower surface of the lower thermal insulation pad 103, and the lower wear-resistant cloth pad 104 is a polyester cloth pad. The lower wear-resistant cloth pad 104 made of polyester has good wear resistance, which improves the service life of the cushion.

[0028] At the same time, a ventilation groove 105 and a plurality of air guide grooves 106 are provided on the upper surface of the upper thermal pad 101. The air guide groove 106 is a mesh structure, and the plurality of air guide grooves 106 are all connected to the ventilation groove 105. The heating component 2 includes a plurality of low-temperature electric heating films 201. The positions of the low-temperature electric heating films 201 and the air guide grooves 106 correspond to each other. Through the corresponding design of the air guide grooves 106 and the low-temperature electric heating films 201, the heat generated by the low-temperature electric heating films 201 can flow in the air guide grooves 106, and the ventilation grooves 105 connected to the air guide grooves 106 can link the plurality of air guide grooves 106 together to ensure that the heat can flow as a whole when the cushion is in use, thereby ensuring that the cushion is heated evenly when in use and improving people's experience of using the cushion. A connecting wire 3 is provided on the outer surface of the heating component 2, and the plurality of low-temperature electric heating films 201 are all electrically connected to the connecting wire 3.

[0029] A charging head 4 is provided at one end of the connecting wire 3, and the charging head 4 is used to connect the power of the heating component 2. A control switch 5 is provided on the connecting wire 3, and the control switch 5 is used to turn on and control the temperature of the heating component 2. A display screen is provided on the upper surface of the control switch 5.

[0030] The same cloth frame 6 is sewn and connected to the outer walls of multiple sides of the cloth pad assembly 1, and one end of the connecting wire 3 passes through the cloth frame 6. A plurality of air holes 7 are provided on the outer surface of the cloth frame 6, and the air holes 7 are connected to the ventilation grooves 105. The design that the ventilation grooves 105 are respectively connected to the air holes 7 and the air guide grooves 106 ensures the circulation of air between the seat cushion and people when the seat cushion is in use, thereby improving the comfort of people when sitting on the seat cushion.

[0031] Among them, a supporting tube 8 is bonded to the inner surface of the cloth frame 6, and the supporting tube 8 is a PE hose. The supporting tube 8 is located between the cloth pad assembly 1 and the cloth frame 6, and one end of the connecting wire 3 is passed through the supporting tube 8. The design of the PE material supporting tube 8 can protect the connecting wire 3 therein. Since the PE material has the properties of bending and twisting, the connecting wire 3 can be prevented from being deformed and broken when being dragged or bent in the cloth frame 6, which has a certain protective effect on the connecting wire 3 and ensures the practicality of people using the cushion.

[0032] In addition, a temperature sensor 202 is bonded between the upper thermal pad 101 and the lower thermal insulation pad 103, wherein the model of the temperature sensor 202 is PT1000, and the temperature sensor 202 is connected to the connecting wire 3. The temperature sensor 202 is located at the center position of multiple low-temperature electric heating films 201. The temperature sensor 202 can sense the temperature of the cushion, and the temperature can be displayed on the display screen of the control switch 5, which is convenient for the operator to check.

[0033] However, a plurality of anti-slip protrusions 107 are respectively bonded to the upper surface of the upper breathable cloth pad 102 and the lower surface of the lower wear-resistant cloth pad 104, and the plurality of anti-slip protrusions 107 are evenly distributed in an array on the upper breathable cloth pad 102 and the lower wear-resistant cloth pad 104. By providing anti-slip protrusions 107 on both the upper breathable cloth pad 102 and the lower wear-resistant cloth pad 104, the seat cushion can be prevented from slipping respectively between the seat sofa and people, avoiding displacement of the seat cushion during use, making it convenient for people to use the seat cushion.

[0034] The working principle of this embodiment: when in use, the operator first places the cushion on a seat or sofa, with the lower wear-resistant cloth pad 104 facing downward and the upper breathable cloth pad 102 facing upward, and then plugs one end of the charging head 4 into the charger connected to the power supply, thereby turning on the power of the heating component 2. At this time, the operator can press the control switch 5 to start the low-temperature electric heating film 201, so that the low-temperature electric heating film 201 generates heat and conducts upward to the upper thermal pad 101, and the heat can flow in the air guide groove 106, thereby ensuring that the heating component 2 heats the cushion evenly, and the temperature sensor 202 can sense the heat temperature of the cushion, and the temperature will be displayed on the display screen of the control switch 5. At this time, the operator can control the temperature of the cushion through the control switch 5 to meet people's use needs;

[0035] During the use of the cushion, the anti-skid protrusions 107 on the lower wear-resistant cloth pad 104 will contact the surface of the seat or sofa, and the anti-skid protrusions 107 on the upper breathable cloth pad 102 will contact the clothes of people sitting on the cushion, so as to achieve double anti-skid, and prevent the cushion from moving during use; at the same time, the ventilation performance of the upper breathable cloth pad 102 not only improves the upward conduction of heat on the upper thermal pad 101, but also ensures the ventilation between people and the cushion, and ensures the air circulation between people and the cushion, thereby improving the comfort of people using the cushion; and since the bottom of the heating component 2 is the lower thermal insulation pad 103, in this way, the downward conduction of heat generated by the low-temperature electric heating film 201 in the heating component 2 is reduced, and the full utilization of the heat of the heating component 2 is ensured. At the same time, it also avoids the hidden danger of aging on the surface of the seat or sofa when the temperature of the heating component 2 is too high, so that people complete the use of the cushion.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
