[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] (1) This new Chinese-style smart furniture based on the Internet of Things technology allows people to rest on the sofa cushion when they need to rest, and the interior of the back cushion is connected to the interior of the sofa cushion by a pull rod and a second support column. When people lean on the back cushion, the back cushion can be tilted back at will as people squeeze it.

When people need to put their feet on the cushion, they can pull out the footrest in the second square groove, so that people can lie flat on the back cushion with their feet on the footrest. In this way, they can adjust the comfort of their posture at will, thereby achieving a comfortable and relaxing effect.

[0012] (2) The new Chinese-style smart furniture based on the Internet of Things technology has a hollow structure inside the side backboard, and a freezing device is arranged inside the side backboard. The freezing device is a freezing storage device. When the sofa is in use, beverages and other drinks can be placed in the freezing device for storage. In this way, the freezing device can cool the drinks and store them. When drinking is needed, the cover above the freezing device can be opened, and the cover can be rotated and closed by a hinge to ensure that the temperature inside the freezing device will not leak, thereby achieving the effect of low-temperature storage of drinks.

[0013] (3) The new Chinese-style smart furniture based on the Internet of Things technology has two storage slots on the top of the cover. When people take low-temperature stored drinks from the inside of the freezer, they can put them in the storage slots after drinking. At this time, the storage slots can store the drinks and prevent the drinks inside from accidentally spilling, thereby achieving the effect of safely storing items.

[0014] (4) The new Chinese style smart furniture based on Internet of Things technology has a total of six massage rollers arranged inside the cushion. The six massage rollers are fixedly mounted on the outer wall of the rotating rollers through connecting blocks. When the shaft is started by the external motor inside the cushion, the six massage rollers will rotate, and the outer wall of the six massage rollers will contact the right wall inside the cushion. The rotation speed of the six massage rollers is controlled by the controller and the side support plate of the discharge trough. When people lean on the cushion, their necks can lean on the cushion, and then the freezing device of the discharge trough above the side support plate can be adjusted with fingers to adjust the speed of the massage rollers, thereby achieving the effect of automatically massaging the neck.

[0015] (5) In the new Chinese-style intelligent furniture based on the Internet of Things technology, a telescopic rod and a support column are arranged on one side wall where the six side backrests are close to each other. The support column and the telescopic rod are internally connected by hydraulic activities. The lower end of the bottom plate is fixedly connected to the outer wall of the four upper hinges. The bottom plate is connected to the sofa cushion. When people sit on the sofa cushion, the bottom plate below the sofa cushion will be affected by gravity. At this time, the sofa cushion will squeeze the upper hinge along with the bottom plate. After the upper hinge is squeezed, the upper hinge will squeeze the telescopic rod. When the upper hinge is pressed downward, the two bottom columns will be squeezed toward the front and rear sides of the square groove by the support column. In this way, the tension spring between the two bottom columns will buffer the overall squeezing force of the upper hinge. At this time, when people sit on the sofa cushion, the gravity on the sofa cushion will be buffered by the support column and the tension spring, thereby achieving the effect of improving the overall comfort of the sofa cushion.
