Description

A sofa with ventilation and heat dissipation mechanism Technical Field

[0001] This utility model relates to the field of sofa technology, specifically to a sofa with a ventilation and heat dissipation mechanism. Background Technology

[0002] Sofas, as a common piece of furniture, generally consist of a supporting frame, an elastic structure, and a seat cushion. The seat cushion is usually made of foam. Although foam cushions have a certain degree of breathability, sitting on a foam cushion for a long time without external ventilation can cause the heat accumulated on top to not dissipate effectively in summer, making it unbearable for the user. Therefore, a sofa with a ventilation and heat dissipation mechanism is needed to solve the above problems. Summary of the Invention

[0003] In view of the problems existing in the prior art, this utility model discloses a sofa with a ventilation and heat dissipation mechanism. The technical solution adopted is as follows: It includes a support frame, which is a hollow structure with an open inner side. An exhaust fan is installed at the top of the support frame, with the exhaust port of the exhaust fan extending into the support frame and the exhaust port extending outwards. The inner opening of the support frame is closed by a support plate. The support plate includes a seat plate and a backrest plate. The interior of the seat plate is an elastic support, and the backrest plate has several ventilation holes. A heat dissipation fin is provided on the rear side of the backrest plate, and the heat dissipation fin is located inside the support frame. Breathable sponge pads are provided on the inner sides of the seat plate and the backrest plate. The support frame provides the main support, and the exhaust fan exhausts the air from the support frame, thereby drawing outside air into the breathable sponge pads for ventilation. The gap between the ventilation holes and the elastic support allows hot air from the breathable sponge pad to be easily drawn into the support frame. The heat dissipation fins increase the contact area between the backrest plate and the air inside the support frame, thus improving heat dissipation.

[0004] As a preferred technical solution of the sofa with ventilation and heat dissipation mechanism of this utility model, the bottom four corners of the support frame are provided with legs, and the height of the legs can meet the height needs of the user.

[0005] As a preferred technical solution of the sofa with ventilation and heat dissipation mechanism of this utility model, the elastic support is an elastic bandage, a serpentine spring, or a combination of an elastic bandage and a serpentine spring, which increases the user's comfort.

[0006] As a preferred technical solution of the sofa with ventilation and heat dissipation mechanism of this utility model, side supports are provided at the left and right ends of the seat and backrest.

[0007] As a preferred technical solution of the sofa with ventilation and heat dissipation mechanism of this utility model, the outer end of the heat dissipation fins is closely attached to the inner side of the support frame. By the heat dissipation fins being close to the support frame, several air ducts can be formed, thereby making the heat dissipation force uniform.

[0008] As a preferred technical solution of the sofa with ventilation and heat dissipation mechanism according to the present invention, a control switch is provided above the side arm, and the control switch is electrically connected to the exhaust fan.

[0009] The beneficial effects of this utility model are as follows: This utility model uses a support frame for main support, and an exhaust fan to exhaust air from the support frame, thereby drawing external air into the breathable sponge pad for ventilation. The gap between the vents and the elastic support allows hot air from the breathable sponge pad to be easily drawn into the support frame. The heat dissipation fins increase the contact area between the backrest and the air inside the support frame, thus improving heat dissipation. The legs of different heights can meet the user's height needs, and the elastic support increases user comfort. The heat dissipation fins, when close to the support frame, form several air ducts, thereby ensuring uniform heat dissipation. Attached Figure Description

[0016] Example 1

[0017] As shown in Figures 1 to 5, this utility model discloses a sofa with a ventilation and heat dissipation mechanism. The technical solution includes a support frame 1, which is a hollow structure with an open inner side. An exhaust fan 102 is installed at the top of the support frame 1, with its exhaust port extending into the support frame 1 and its exhaust port extending outward. The inner opening of the support frame 1 is closed by a support plate 2. Support legs 101 are provided at the four corners of the bottom of the support frame 1, and the support legs 101 of different heights can meet the height needs of the user. The support plate 2 includes a seat plate 21 and a backrest 22. The seat plate 21 has an elastic support 201 inside, and the backrest 22 has several ventilation holes 204. A heat dissipation fin 203 is provided on the rear side of the backrest 22, and the heat dissipation fin 203 is located inside the support frame 1. A breathable sponge pad 3 is provided on the inner side of the seat plate 21 and the backrest 22. The elastic support 201 is an elastic band. A combination of serpentine springs or elastic bandages and serpentine springs, along with elastic supports 201, increases user comfort. Side supports 202 are provided at the left and right ends of the seat 21 and backrest 22. A control switch 205 is located above the side supports 202 and is electrically connected to the exhaust fan 102. The outer end of the heat dissipation fins 203 is pressed against the inner side of the support frame 1. By pressing the heat dissipation fins 203 against the support frame 1, several air ducts can be formed, thereby making the heat dissipation airflow uniform. The support frame 1 provides the main support, and the exhaust fan 102 exhausts the air from the support frame 1, thereby drawing external air into the breathable sponge pad 3 for ventilation. The gap between the vent 204 and the elastic support 201 facilitates the extraction of hot air from the breathable sponge pad 3 into the support frame 1. The heat dissipation fins 203 increase the contact area between the backrest 22 and the air inside the support frame 1, thereby improving heat dissipation.

[0018] The working principle of this utility model is as follows: When in use, the exhaust fan 102 is started by controlling the switch 205, and a negative pressure is generated inside the support frame 1. The heat on the breathable sponge pad 3 enters the support frame 1 through the elastic support 201 and the vent 204, and then is discharged. Cool air enters the breathable sponge pad 3 to cool down the user's sitting or lying area. The heat dissipation fins 203 conduct heat to the backrest 22 to cool it down and increase the heat dissipation intensity.
