DETAILED DESCRIPTION

[0021] 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.

[0022] A self-heating leather sofa comprises a sofa body 1, wherein a heating structure is arranged in a seat cushion and a backrest of the sofa body 1, and the seat cushion and the backrest of the sofa are heated by the heating structure, wherein the heating structure comprises a supporting frame of the sofa body 1, wherein the supporting frame is a frame of a sofa in the prior art, wherein a circle of baffles is arranged around the supporting frame, and a partition fixedly connected to the baffles is arranged around the supporting frame, wherein the partition and the baffles around the supporting frame constitute a mounting groove 2 with an opening facing the surface of the sofa, wherein the mounting groove 2 arranged in the seat cushion opens toward the surface of the seat cushion, and the mounting groove 2 arranged in the backrest opens toward the surface of the backrest, that is, both face the direction in which a human body sits, wherein a plurality of snake springs 3 are arranged at the opening of the mounting groove 2, and a plurality of sponge pads 4 are filled between the snake springs 3 and the fabric on the surface of the sofa, wherein the arrangement of the snake springs 3 and the sponge pads 4 is based on the prior art, and is used to increase the elasticity and softness of the sofa;

[0023] A plurality of constant temperature electric heating tubes 5 are installed in the installation groove 2. The plurality of constant temperature electric heating tubes are arranged away from the snake spring 3. The constant temperature electric heating tubes 5 adopt low-power electric heating tubes in the prior art, and the heating temperature is about 30°C.

[0024] The constant temperature electric heating tube 5 generates heat to heat the air in the installation groove 2, and the hot air diffuses through the sponge to reach the fabric on the surface of the sofa body 1 to heat the fabric, thereby increasing the surface temperature of the sofa; the constant temperature electric heating tube 5 is located in the heating groove away from the fabric on the surface of the sofa body 1, so when a person sits on the sofa and causes the sofa to sag inward, the constant temperature electric heating tube 5 will not be pressed, thereby protecting the constant temperature electric heating tube 5 from damage.

[0025] According to a preferred technical solution, a layer of thermal insulation film is glued on the bottom and inner wall of the installation groove 2.

[0026] The heat preservation film prevents the heat in the mounting groove 2 from being dissipated through the side wall of the mounting groove 2, thereby ensuring to the greatest extent that the heat in the mounting groove 2 can only diffuse outward through the opening of the mounting groove 2, thereby ensuring to the greatest extent that the heat in the mounting groove 2 can only diffuse to the surface of the seat cushion and the backrest.

[0027] A preferred technical solution is that a bellows 6 is provided in the sofa body 1, an air inlet 7 is provided at the bottom of the sofa body 1, a fan is provided in the bellows 6, a side of the bellows 6 corresponding to the negative pressure end of the fan is connected to the air inlet 7 through an air inlet pipe 8, and a side of the bellows 6 corresponding to the positive pressure end of the fan is connected to the mounting slot 2 through an air outlet pipe 10, the negative pressure end of the fan is the air inlet end of the fan, and the positive pressure end of the fan is the air outlet end of the fan.

[0028] By starting the fan, the air at the air inlet 7 is transported to the installation groove 2, forcing the hot air in the installation groove 2 to flow and accelerate the diffusion to the surface of the seat cushion and the backrest. The sponge pad 4 has abundant pores. The leather fabric of the sofa is usually made of animal skin, so it has good air permeability. Therefore, controlling the fan to slowly drive the hot air flow in the installation groove 2 will not cause the sofa to bulge.

[0029] According to a preferred technical solution, at least one layer of dustproof net is provided in the air inlet 7 , and dust is isolated by the dustproof net to prevent excessive dust from being sucked into the sofa body 1 .

[0030] A preferred technical solution is that a side opening 11 connected to the mounting groove 2 is opened on one side of the sofa body 1, a mounting frame 14 is provided in the mounting groove 2, the constant temperature electric heating tube 5 is installed on the mounting frame 14, the outer end of the mounting frame 14 is fixedly connected to an outer plate 12 matching the side opening 11, and both sides of the mounting frame 14 are installed on the inner wall of the mounting groove 2 through drawer slide rails, and the mounting frame 14 can slide outward through the side opening 11.

[0031] The installation frame 14 slides through the drawer slide rail, so that the installation frame 14 can be pulled out of the sofa body 1 through the side opening 11. After the constant temperature electric heating tube 5 is in the sofa body 1 for a long time, a layer of dust will be adhered to the surface, which will reduce the thermal efficiency of the constant temperature electric heating tube 5 and cause increased power consumption. By pulling out the installation frame 14, the dust on the constant temperature electric heating tube 5 can be cleaned.

[0032] According to a preferred technical solution, an inwardly arranged step 15 is provided on the edge of the side opening 11, and the outer panel 12 abuts against the step 15. After the outer panel 12 abuts against the step 15, the outer end of the outer panel 12 is flush with the side of the sofa body 1, thereby preventing the outer panel 12 from protruding from the side of the sofa and affecting the appearance of the sofa.

[0033] According to a preferred technical solution, a first magnet 16 is disposed on the inner side of the outer plate 12 , and a second magnet 17 that attracts the first magnet 16 is disposed on the side of the sofa body 1 .

[0034] The outer panel 12 is fixed to the side wall of the sofa body 1 by the attraction between the first magnet 16 and the second magnet 17 .

[0035] According to a preferred technical solution, a pull ring 13 is provided at the outer end of the outer plate 12 .

[0036] The installation frame 14 can be easily pulled out by the pull ring 13 .
