Description

Technical Field

[0001] This utility model relates to the field of sofa technology, and in particular to an active ventilation sofa structure. Background Technology

[0002] As an indispensable piece of upholstered furniture in modern homes, the comfort of sofas directly impacts the user experience. However, traditional sofas have significant shortcomings in hot climates, particularly the lack of effective ventilation and heat dissipation systems. This causes heat buildup and sweating in the back and buttocks areas when users sit for extended periods, severely affecting comfort and requiring further improvement. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an actively ventilated sofa structure.

[0004] An active ventilation sofa structure designed for this purpose includes a sofa frame and a seat cushion and a back cushion disposed on the sofa frame. An installation space is provided between the seat cushion and the back cushion. A ventilation module is disposed in the installation space and the ventilation module is movable relative to the sofa frame.

[0005] The sofa frame is equipped with a locking module for restricting the forward and backward movement of the ventilation module.

[0006] Preferably, the ventilation module includes a movable frame that is movably disposed within the installation space, an air outlet duct is disposed on the front side of the movable frame, the air outlet duct is rotatably disposed relative to the movable frame, a plurality of air outlets are arranged on the front side of the air outlet duct, and a connecting pipe is disposed on the rear side of the air outlet duct.

[0007] Preferably, the left and right ends of the air outlet pipe are provided with rotating shafts, which are rotatably connected to the movable frame. The rotating shafts are threadedly connected with locking knobs, which can abut against the surface of the movable frame to constrain the rotating shafts to rotate relative to the movable frame.

[0008] Preferably, the movable frame is provided with guide grooves on its left and right sides, and the movable frame is provided with guide blocks that are movably inserted into the guide grooves.

[0009] Preferably, the locking module includes locking racks disposed on the left and right sides of the movable frame and locking blocks disposed on the left and right sides of the sofa frame.

[0010] The locking tooth block is configured to move left and right relative to the sofa frame and moves between a first position and a second position;

[0011] When the locking tooth block is in the first position, the locking tooth block engages with the locking rack to constrain the moving frame to move back and forth relative to the sofa frame;

[0012] The locking tooth block is connected to an operating lever;

[0013] The locking teeth are connected to the sofa frame by a spring.

[0014] Preferably, the sofa frame has mounting cavities and through holes communicating with the mounting cavities on its left and right sides.

[0015] The locking tooth block is movable within the mounting cavity;

[0016] The operating lever extends outward through the through hole.

[0017] Preferably, the operating lever is connected to an operating handle.

[0018] Compared with existing technologies, the ventilation module of this invention can be connected to an external fan to blow or draw air onto the user sitting on the sofa, thereby promoting airflow and removing heat. Furthermore, the movable design of the ventilation module allows its position to be adjusted according to the thickness of the backrest cushions, meeting different usage needs.

[0032] See Figures 1-5 An actively ventilated sofa structure includes a sofa frame 10, a seat cushion 20, and a back cushion 30 mounted on the sofa frame 10. An installation space 60 is provided between the seat cushion 20 and the back cushion 30. A ventilation module 40 is disposed within the installation space 60 and is movable relative to the sofa frame 10. The sofa frame 10 is provided with a locking module 50 to restrain the forward and backward movement of the ventilation module 40. The ventilation module can be connected to an external fan to blow or draw air onto the user sitting on the sofa, thereby promoting airflow and removing heat. The movable nature of the ventilation module allows its position to be adjusted according to the thickness of the back cushion, meeting different usage needs.

[0033] See Figure 3 The ventilation module 40 includes a movable frame 410 movably disposed within the installation space 60. An air outlet duct 420 is disposed on the front side of the movable frame 410. The air outlet duct 420 is rotatably disposed relative to the movable frame 410. Multiple air outlets 430 are arranged on the front side of the air outlet duct 420, and a connecting pipe 440 is disposed on the rear side of the air outlet duct 420. As the rotatably disposed air outlet duct 420 rotates, the orientation of the air outlets 430 can be adjusted to meet user needs.

[0034] The connecting pipe 440 uses a corrugated pipe to connect to an external fan. The fan can be an exhaust fan or a blower to dissipate heat from the human body by blowing or exhausting air. The fan can be installed at the bottom of the frame 10.

[0035] See Figure 5The air outlet duct 420 has rotating shafts 421 at both ends, which are rotatably connected to the movable frame 410. Each rotating shaft 421 is threadedly connected to a locking knob 405, which abuts against the surface of the movable frame 410 to constrain the rotation of the rotating shaft 421 relative to the movable frame 410. When the locking knob 405 is tightened and pressed against the surface of the movable frame 410, the friction between the locking knob 405 and the movable frame 410 constrains the rotation of the rotating shaft 421 relative to the movable frame 410. When the user needs to adjust the angle of the air outlet duct 420, the locking knob 405 must be loosened first, and then the angle of the air outlet duct 420 can be adjusted.

[0036] See Figure 5 The movable frame 410 is provided with guide grooves 412 on its left and right sides, and the movable frame 410 is provided with guide blocks 100 that are movably inserted into the guide grooves 412.

[0037] See Figure 5 The locking module 50 includes locking racks 510 disposed on the left and right sides of the movable frame 410 and locking blocks 520 disposed on the left and right sides of the sofa frame 10. The locking blocks 520 are movably positioned relative to the sofa frame 10, moving between a first position and a second position. When the locking blocks 520 are in the first position, they engage with the locking racks 510 to constrain the movable frame 410 from moving back and forth relative to the sofa frame 10. An operating lever 540 is connected to the locking blocks 520. A spring 530 is connected to the locking blocks 520 and the sofa frame 10. Locking and unlocking can be achieved by moving the locking blocks 520. The spring 530 applies force to keep the locking blocks 520 in the first position, thus maintaining the locked state. To unlock, the operating lever 540 needs to be manually pulled to move the locking blocks 520 from the first position to the second position, disengaging them from the locking racks 510.

[0038] See Figure 5 The sofa frame 10 has mounting cavities 110 and through holes 120 communicating with the mounting cavities 110 on its left and right sides; the locking tooth block 520 is movably disposed in the mounting cavity 110; the operating rod 540 extends to the outside through the through hole 120.

[0039] See Figure 5 The operating lever 540 is connected to an operating handle 550.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
