[0029] See also Figure 1 to Figure 2 A pneumatic massage system for an electric sofa includes a massage airbag 1, a lumbar support airbag 2 and an air supply mechanism 3. The air supply mechanism 3 includes an air supply device 31, a main and branch pipeline 32, a first solenoid valve 33 and a second solenoid valve 34.

[0030] The gas supply device 31 is responsible for providing gas pressure and delivering gas into the main and branch pipelines 32; the gas supply device 31 is an air pump. The input end of the main and branch pipelines 32 is connected to the output end of the gas supply device 31, and the gas pressure is provided by the gas supply device 31 and delivered to the main and branch pipelines 32. The output end of the main and branch pipelines 32 is respectively connected to the input end of the first solenoid valve 33 and the input end of the second solenoid valve 34, that is, the gas in the main and branch pipelines 32 can be delivered to the first solenoid valve 33 and the second solenoid valve 34, which means that the main and branch pipelines 32 have multiple output ends.

[0031] The output end of the first solenoid valve 33 is connected to the input end of the massage airbag 1. By controlling the switch state of the first solenoid valve 33, the flow of gas can be controlled, thereby realizing the inflation and deflation of the massage airbag 1, and further realizing the massage airbag 1 to massage the user. The output end of the second solenoid valve 34 is connected to the input end of the lumbar support airbag 2. By controlling the switch state of the second solenoid valve 34, the flow of gas can be controlled, thereby realizing the inflation and deflation of the lumbar support airbag 2, and further realizing the lumbar support airbag 2 can support the user's waist and provide comfort.

[0032] In actual use, when the user needs to perform a massage, the controller or remote controller sends a command to control the switch state of the first solenoid valve 33 and the second solenoid valve 34. When the first solenoid valve 33 is opened, gas flows from the main branch pipeline 32 into the massage airbag 1 to inflate and deflate it, thereby achieving a massage effect. When the second solenoid valve 34 is opened, gas flows from the main branch pipeline 32 into the lumbar support airbag 2 to inflate it and provide lumbar support.

[0033] In this embodiment, through the highly integrated setting of the air supply mechanism 3, it can be realized that one air supply device 31 can simultaneously inflate and deflate the massage airbag 1 and the lumbar support airbag 2, and the massage airbag 1 and the lumbar support airbag 2 can respectively realize independent operation through the first solenoid valve 33 and the second solenoid valve 34. The pneumatic massage system has high integration and low manufacturing cost, and provides a more convenient and efficient solution for the massage function of the electric sofa, thereby improving the user experience.

[0034] See also Figure 1 , there are two groups of massage airbags 1, and two first solenoid valves 33 are provided. The two first solenoid valves 33 are connected to the two groups of massage airbags 1 in a one-to-one correspondence. One first solenoid valve 33 corresponds to one group of massage airbags 1, and one group of massage airbags 1 includes two airbags that are connected to each other; that is, one first solenoid valve 33 can inflate or deflate the two airbags at the same time. By setting up two groups of massage airbags 1, the massage comfort provided by the pneumatic massage system to the user can be provided; the massage area is larger, giving the user a better massage experience. In addition, each group of massage airbags 1 corresponds to one first solenoid valve 33, so different groups of massage airbags 1 can bring different massage experiences to the user (such as massage force, massage amplitude, massage time, etc.).

[0035] Of course, in other embodiments, the massage airbags 1 may also be arranged in three or more groups, and each group of massage airbags 1 may also be arranged with three or more airbags.

[0036] See also Figure 2 , the air supply mechanism 3 also includes an auxiliary electromagnetic valve 35, which is connected to the input end of the lumbar support airbag 2. The second electromagnetic valve 34 can inflate or deflate the lumbar support airbag 2, and the function of the lumbar support airbag 2 is to support the user's waist by inflation. Therefore, when the user uses the electric sofa, the waist will exert a certain squeezing force on the lumbar support airbag 2. The air supply device 31 inflates the massage airbag 1 and the lumbar support airbag 2 at the same time, and the massage airbag 1 is a process of continuous inflation and deflation during the massage process. In order to prevent the lumbar support airbag 2 from being deflated due to the downward pressure of the user's waist after inflation, an auxiliary electromagnetic valve 35 is also provided at the input end of the lumbar support airbag 2; when the lumbar support airbag 2 is inflated, the auxiliary electromagnetic valve 35 works to ensure the pressure of the lumbar support airbag 2, so that the lumbar support airbag 2 can support the user's waist and improve the comfort of use.

[0037] See also Figure 1, two lumbar support airbags 2, two second solenoid valves 34 and two auxiliary solenoid valves 35 are provided, and the lumbar support airbags 2, the second solenoid valves 34 and the auxiliary solenoid valves 35 are connected one by one. The input ends of the two second solenoid valves 34 are connected to the output ends of the main branch pipeline 32, one second solenoid valve 34 corresponds to one lumbar support airbag 2, and one auxiliary solenoid valve 35 corresponds to one lumbar support airbag 2. In this way, the effective area of ​​the lumbar support airbag 2 can be increased, and the air supply device 31 can be highly integrated.

[0038] See also Figure 5 The main branch pipeline 32 includes a main pipeline 321 and a first branch pipeline 322 and a second branch pipeline 323 connected to the main pipeline 321. The first branch pipeline 322 is connected to the first electromagnetic valve 33, and the second branch pipeline 323 is connected to the second electromagnetic valve 34. The gas supply device 31 delivers gas to the main pipeline 321, and then delivers gas to the first electromagnetic valve 33 and the second electromagnetic valve 34 through the first branch pipeline 322 and the second branch pipeline 323, respectively, and finally delivers gas to the massage airbag 1 and the lumbar support airbag 2. As mentioned above, there are two first electromagnetic valves 33 and two second electromagnetic valves 34, so there are also two first branch pipelines 322, which correspond to the two first electromagnetic valves 33 one by one, and there are also two second branch pipelines 323, which correspond to the two second electromagnetic valves 34 one by one. By setting the main branch pipeline 32 in this way, the integration of the gas supply mechanism 3 can be guaranteed.

The housing 36 brings the gas supply device 31, the main and branch pipelines, the first solenoid valve 33 and the second solenoid valve 34 together, which not only plays a protective role, avoids the bending of the pipeline, improves the stability and air tightness, but also further improves the integration.
