Detailed implementation mode

[0024] Referring to Figure 1-6 , a controllable and comfortable sofa for furniture, including a base 1, a backrest layer 2 and an electric control component. The electric control component is composed of a control element and an output element, and can control each electric component. A seating cushion layer 3 is arranged on the top of the base 1. Two armrests 4 are respectively arranged on both sides of the seating cushion layer 3. Two headrest cushions 5 are arranged on the top of the backrest layer 2. The headrest cushions 5 are used for placing the head of a person when using the sofa. Two connecting pipes 6 are fixedly connected to the bottom of each headrest cushion 5. Each headrest cushion 5 is connected with a massage device. A sliding groove 8 is opened on the top of the base 1. A slider 9 is slidably arranged in the sliding groove 8. The slider 9 is fixedly arranged at the bottom of the seating cushion layer 3 and is slidably connected with the sliding groove 8 through a slide rail. In this way, the slider 9 and the sliding groove 8 are disengaged after sliding to the end, so that the seating cushion layer 3 and the base 1 can be disassembled. The top of the base 1 is provided with a soft cushion structure made of the same material as the seating cushion layer 3. In this way, the combined area of the two components will be twice that of the seating cushion layer 3, which is better for use and saves space when the seating cushion layer 3 is used alone. The slider 9 is connected with a transmission structure.

[0025] The massage device includes a back massage structure and a head massage structure. The back massage structure includes a liquid cavity 7 opened in the backrest layer 2. An evaporation liquid is arranged in the liquid cavity 7. The evaporation liquid is heated and evaporated, and outputs gas. The two connecting pipes 6 connected to each headrest cushion 5 all penetrate through the liquid cavity 7. A plurality of connection ports 10 are opened on the side wall of the backrest seat through which the liquid cavity 7 penetrates. A massage ball 12 is communicated at one end of each connection port 10 away from the liquid cavity 7. The massage ball 12 adopts a rubber airbag structure and is communicated with the connection port 10. When the massage ball 12 is impacted by the irregular evaporation liquid gas, it will expand irregularly, so as to play a role in massaging the back of the user. A heat insulation layer 11 is jointly arranged for the plurality of connection ports 10 connected to each liquid cavity 7. The heat insulation layer 11 has heat preservation and heat insulation effects. On the one hand, the energy heated by the liquid cavity 7 will not escape, and on the other hand, it avoids the problem that the heating of the backrest layer 2 of the sofa scalds the user. A heating resistor is arranged between the heat insulation layer 11 and the liquid cavity 7. The other side of the heat insulation layer 11 is communicated with the outside. A plurality of massage balls 12 are all arranged on the heat insulation layer 11. The plurality of massage balls 12 located on the same heat insulation layer 11 are arranged in a square array. The evaporation liquid is set as an alcohol liquid with a boiling point of 80°.

[0026] The head massage structure includes a receiving cavity 13 formed in the headrest 5. An air flow channel 14 is formed in the receiving cavity 13. The air flow channel 14 is respectively communicated with the tops of two connecting pipes 6. The other side of the air flow channel 14 is communicated with an air outlet pipe 15. An eye mask 17 is arranged on the side of the air outlet pipe 15 away from the air flow channel 14. When in use, the evaporation liquid gas acts on the user's head through the eye mask, achieving the effect of head and eye massage. The advantage of this is that the heat of the evaporation liquid gas is reused to achieve the effect of hot compress on the eyes, and at the same time, it plays the role of massaging the head. A rotating plate 16 is fixedly arranged on the side of the eye mask 17 close to the air outlet pipe 15. The rotating plate 16 is rotatably connected to the inner top wall of the receiving cavity 13. The position of the eye mask 17 can be adjusted through the rotating plate 16, which is convenient for adjusting users of different body types. A buffer pad 18 is fixedly connected to the inner wall of the receiving cavity 13 away from the eye mask 17. The buffer pad 18 is used for fixing and protecting the back of the head. A part of one connecting pipe 6 in the liquid cavity 7 located in the backrest layer 2 is connected with a first gear 19. A transmission cavity 21 for receiving the first gear 19 is formed in the backrest layer 2. The first gear 19 meshes with a second gear 20. The second gear 20 is connected with a driving motor 22. The driving motor 22 is fixedly arranged on the inner top wall of the transmission cavity 21. The output shaft of the driving motor 22 is coaxially and fixedly connected with the second gear 20.

[0027] Threaded layers 30 that cooperate with each other are arranged at the connection between the connecting pipe 6 and the corresponding first gear 19 connected thereto. The connecting pipe 6 and the first gear 19 are connected by screw transmission. In this way, when the driving motor 22 rotates, the first gear 19 and the second gear 20 will drive the connecting pipe 6 to move in the up and down directions, realizing the adjustment of the height of the headrest 5. The bottom side walls of the two connecting pipes 6 located in the same liquid cavity 7 are fixedly connected together with a fixing rod 29. This can not only limit the maximum moving distance of the connecting pipe 6 but also drive the connecting pipe 6 on the other side to move through the operation of the driving motor 22. The transmission structure includes a hydraulic cylinder 24 embedded in the slider 9. The top of the hydraulic cylinder 24 is flush with the upper end surface of the slider 9. A limiting groove 25 is communicated with the top of the sliding groove 8. A threaded rod 26 is horizontally and fixedly connected to the limiting groove 25. The threaded rod 26 is threadedly connected with a movable block 23. The bottom of the movable block 23 is fixedly arranged on the top wall of the hydraulic cylinder 24. The threaded rod 26 is fixedly connected with a transmission motor 27. When the transmission motor 27 rotates, it will make the movable block 23 move horizontally through the threaded rod 26. The transmission motor 27 is fixedly arranged in the seat cushion layer 3. The transmission motor 27 is a forward and reverse motor. The slider 9 is arranged on the side close to the backrest layer 2. A fixing block 31 is fixedly arranged on the side of the bottom of the seat cushion layer 3 away from the backrest layer 2. The fixing block 31 has the same specification as the slider 9 and is hermetically and slidably connected to the sliding groove 8.

[0028] On each of the two side backrests 4, a control box 28 is fixedly arranged, and control buttons are arranged in the control box 28. An electric control component is arranged in each control box 28 and is correspondingly connected to the control buttons. Each electric control component starts the massage device and the transmission structure by controlling the drive motor 22, the heating resistance wire, the hydraulic cylinder 24, and the transmission motor 27 on the corresponding side. The air outlet pipe 15 adopts a rubber hose structure, so that the air outlet pipe 15 can be stretched and twisted to a certain extent. The heights of the slider 9 and the seat cushion layer 3 are the same as the height of the base 1, so as to keep the two split parts at the same height and make the upper end surface of the combined body consistent.

[0029] When the present invention is in use, by starting the transmission motor 27, the movable block 23 is moved to the leftmost end of the limit groove 25 in the initial state. When the base 1 and the seat cushion layer 3 are separated from each other by moving the slider 9, the slider 9 and the fixed block 31 are respectively located on both sides of the seat cushion layer 3, and the two together play a supporting role for the seat cushion layer 3.

[0030] When recovering the seat cushion layer 3, first start the hydraulic cylinder 24 to lift the whole seat cushion layer 3 and make the bottom of the seat cushion layer 3 flush with the top of the base 1. Then start the transmission motor 27 and make it rotate in the reverse direction and retract the hydraulic cylinder 24. In this way, under the screw drive of the threaded rod 26 and the movable block 23, the slider 9 enters the sliding groove 8 and the seat cushion layer 3 is placed flat on the upper end surface of the base 1. At this time, the user only needs to push the seat cushion layer 3 forward to make the seat cushion layer 3 return to its original state. The advantage of this is that there is no need to manually lift the seat cushion layer 3, which saves effort and is convenient to use.
