[0047] Furthermore, the first and second connecting branches are connected in parallel, with the electromagnetic pressure-maintaining valve 11 and the first electromagnetic valve 12 respectively disposed on the first and second connecting branches for easy control. During inflation, the electromagnetic pressure-maintaining valve is energized to open, while the first electromagnetic valve is de-energized to close and maintain pressure. The first connecting branch is then connected, allowing air to flow into the regulating airbag through the first and second pipelines. During deflation, the electromagnetic pressure-maintaining valve is de-energized to close and maintain pressure, while the first electromagnetic valve is energized to open. Air in the regulating airbag flows along the second pipeline to the second connecting branch and is discharged from the exhaust port.

[0048] It should be noted that the massage mechanism and adjustable airbag installation structure can be applied to the backrests of various chairs, including sofas, leisure chairs, office chairs, mahjong chairs, and nursing chairs. Furthermore, the massage mechanism can be positioned at different locations on the inner side of the backrest to control the massage intensity for different parts of the body, such as the waist and neck.

[0049] Furthermore, buttocks-beautifying airbags 16 are provided on the inner sides of the armrests 3 on both sides; a third connecting branch is provided in parallel between the first pipeline 14 and the second pipeline 15, and a second solenoid valve 17 is provided on the third connecting branch. An inflation short tube 18 is extended outward from the third connecting branch, and the inflation short tube 18 is connected to the buttocks-beautifying airbag 16 through a second air guide tube; an air vent 19 is provided on the second solenoid valve 17;

[0050] At the same time, the air pump 9 and the second solenoid valve 17 are turned on. The second solenoid valve 17 can connect the third connecting branch pipe and the short inflation pipe 18 to inflate the buttocks-beautifying airbag 16.

[0051] At the same time, the air pump 9 and the second electromagnetic valve 17 are closed. The second electromagnetic valve 17 can use the third connecting branch to allow the air in the buttocks beautifying airbag 16 to be discharged from the air vent 19 along the second air duct.

[0052] In this technical solution, the buttocks-enhancing airbag is located inside the armrest. Opening the air pump and second solenoid valve inflates the buttocks-enhancing airbag. Closing the air pump and second solenoid valve simultaneously releases the air inside the buttocks-enhancing airbag through the vent. IC programming controls the opening and closing of the air pump and second solenoid valve, creating a complete inflation and deflation routine for the buttocks-enhancing airbag.

[0053] Furthermore, the backrest frame 4 is an integrally formed iron frame. In this technical solution, the backrest frame in the seat is integrally formed, which is more environmentally friendly and the chair as a whole can be made without glue or formaldehyde.

[0054] Furthermore, connecting blocks 20 are fixedly provided on both sides of the lower portion of the backrest frame 4. A rotating shaft 21 is fixedly provided at the outer end of the connecting block 20. A connecting piece is fixedly inserted and inserted into the inner side of the armrest 3. The connecting blocks 20 and the rotating shaft 21 are correspondingly provided with sockets 22 that cooperate with the connecting piece. The backrest 2 is rotatably connected to the armrest 3 through the cooperation of the rotating shaft 21 and the connecting piece. In this technical solution, the armrest, seat, and backrest are installed separately. The backrest is rotatably connected to the armrest via the rotating shaft. After rotating 90 degrees, the backrest can be flatly placed between the armrests, making packaging very compact and reasonable, reducing transportation costs and preventing damage to the backrest during transportation.

[0055] Furthermore, the backrest frame 4 and the massage core assembly 5 are rotatably connected via a pair of connecting shafts 23. In this technical solution, the backrest frame and the massage core assembly are rotatably connected via connecting shafts, which has a simple structure and is easy to assemble and disassemble. Other effective hinge structures can also be used, such as clamping the massage core assembly with a rotating clamp.

[0056] Furthermore, the massage movement assembly 5 includes movement-fixing sponges 24, each having an assembly slot 25 defined therein. The movement 6 fits within the assembly slot 25, and the massage head 7 extends out of the assembly slot 25. Connecting holes 26 are provided on the lower sides of the movement-fixing sponges 24, which mate with the connecting shaft 23. In this technical solution, the movement-fixing sponges are used to secure the movement, improving its assembly stability and facilitating its connection to the connecting shaft.

[0059] In this specific embodiment, in order to address the problem that the massage head of the existing breastfeeding seat always presses against the user's waist, causing discomfort, and cannot provide different massage intensity experiences for different groups of people, the above solution is to set an adjustable airbag on the back side of the massage movement assembly. The inflating of the adjustable airbag can push the massage movement assembly to flip outward so that the massage head extends beyond the plane of the backrest frame. The compression of the adjustable airbag can cause the massage movement assembly to flip inward and hide in the backrest. The cam is energized to open the valve body and release the air from the valve body, and the cam is energized to open the valve body, and the cam is energized to release the air from the valve body, and the cam is energized to release the air from the valve body, and the cam is energized to release the air from the valve body. The opening and closing states of the air pump, electromagnetic pressure-maintaining valve and the first electromagnetic valve are controlled through IC programming in the seat, thereby forming a set of procedures for adjusting the inflation and deflation of the airbag. The amount of inflation and deflation is used to achieve the required height of the airbag, and then the rotation angle of the massage head on the massage movement assembly can be controlled to achieve control of the massage intensity. The massage head can also be retracted into the inside of the backrest to prevent the user from feeling uncomfortable when being pushed up when sitting for a long time.

[0060] It should be noted that the installation structure of the massage mechanism and adjustable airbag can be applied to the backrests of various chairs, including sofas, leisure chairs, office chairs, mahjong chairs, and nursing chairs. Furthermore, the massage mechanism can be installed at different locations on the inner side of the backrest, thereby controlling the massage intensity for different parts of the body, such as the waist and neck.

[0061] In addition, if Figure 13 As shown, the operation of the seat is wirelessly controlled by a remote control, which is more convenient.

[0062] The operating principle of the MP660 nursing chair is as follows:

[0063] After turning on the power button, the nursing chair is in standby mode. When the massage button is pressed for the first time, the electromagnetic pressure maintaining valve starts working, and the air pump inflates the adjustment airbag through the first air duct. After the airbag is full, the first solenoid valve will deflate for 0.5S, and the waist kneading motor on the massage movement assembly starts working and the massage head runs. While the waist kneading motor is working, the user can use the massage strength button to adjust the saturation of the airbag and control the operating angle of the massage head to achieve the purpose of adjusting the strength.
