[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1-3 As shown, to achieve the above objectives, this utility model provides the following technical solution: A detachable multifunctional sofa includes a main frame 1 and a backrest 2. Sockets 14 are installed on one side of the main frame 1 near both the front and back surfaces. Inserts 7 are clamped inside the sockets 14. A positioning shaft 10 is installed on one side of the insert 7 near the top. A flip-up column 8 is sleeved on the outer surface of the positioning shaft 10. The backrest 2 is installed on the top of the flip-up column 8. A rotating shaft 12 is installed on one side of the main frame 1 near the bottom. Clamping brackets 11 are installed on both sides of the outer surface of the rotating shaft 12. A positioning hole 9 is provided on one side of the insert 7 at the position of the clamping bracket 11. The clamp 11 is fitted into the positioning hole 9. A limit rod 13 is installed on one side of the main frame 1 at the bottom of the rotating shaft 12. The limit rod 13 passes through the inside of the clamp 11. The rotating shaft 12 and the clamp 11 are connected by a thread. The threads on the outer surface of the rotating shaft 12 are reversed, which makes it easy to drive the clamp 11 to move in opposite directions through the rotating shaft 12. A seat cushion 4 is installed on the top of the main frame 1, and a back cushion 3 is installed on one side of the backrest 2. Support columns 19 are installed at the four corners of the bottom of the main frame 1. An elastic cloth cover 5 is installed on the outer surface of the main frame 1 near the bottom to isolate and protect the main frame 1.

[0027] like Figure 4 and Figure 5 As shown, a limiting seat 24 is installed in the middle of one side of the insertion post 7. A limiting post 25 is installed inside the limiting seat 24. A spring 23 is installed on the outer surface of the limiting post 25 on the upper surface of the limiting seat 24 via a spring seat. A limiting tooth 26 is provided on the outer surface of the flip post 8. The end of the limiting post 25 is locked inside the limiting tooth 26. The flip post 8 is fixed by the limiting post 25.

[0028] The working principle of a detachable multifunctional sofa based on Embodiment 1 is as follows: After preparing the present invention, insert the bottom post 7 of the backrest 2 into the socket 14. After completion, rotate the shaft 12, which drives the clamping frame 11 to move laterally. The clamping frame 11 and the positioning hole 9 fix the post 7, thus fixing the backrest 2. After completion, the present invention can be used. When it is necessary to adjust the angle of the backrest 2, pull down the limiting post 25 to separate the limiting post 25 from the limiting tooth 26, so that the backrest 2 can be flipped over and the angle of the backrest 2 can be adjusted. After completion, the spring 23 squeezes the limiting post 25, which is inserted into the limiting tooth 26, thereby fixing the flipping post 8, thus adjusting the angle of the backrest 2, and thus using the present invention. At this point, the working process of the device is completed.

[0029] Example 2

[0030] like Figure 4 As shown, the present invention proposes a detachable multifunctional sofa. Compared with Embodiment 1, this embodiment further includes: a ventilation box 16 located in the middle of the seat cushion 4, with a ventilation hole 17 at the top of the ventilation box 16; an equipment box 6 installed in the middle of the bottom of the main frame 1; an exhaust fan 22 installed at the bottom of the equipment box 6; the input end of the exhaust fan 22 connected to the equipment box 6 via an air inlet pipe 15; and the output end of the exhaust fan 22 connected to the interior of the ventilation box 16 via an air supply pipe 18. A heating box 20 is installed in the middle of the air supply pipe 18, with a heating wire 21 installed inside the heating box 20. The gas is heated by the heating box 20 and the heating wire 21. A controller 27 is installed inside the equipment box 6, and the controller 27 includes a wireless control module, a data storage module, and a power supply module.

[0031] In this embodiment, when ventilation of the seat cushion 4 is required, the exhaust fan 22 is activated, and the external air is drawn away through the exhaust fan 22 and the air inlet pipe 15, and delivered to the ventilation box 16 through the air delivery pipe 18. The air is then sprayed out through the ventilation hole 17 on the top of the ventilation box 16, thereby blowing air on the user. When the seat cushion 4 needs to be heated, the heating wire 21 is activated, and the heating box 20 is heated through the heating wire 21, thereby heating the gas and thus heating the seat cushion 4.

[0032] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
