[0031] Specifically: A perimeter is set around the base plate 1, and the elastic mesh 29 and elastic rubber plate 33 are fixedly connected to the perimeter. A face mask is covered on top of the elastic rubber plate 3. The face mask is connected to the perimeter by a hanger. The face mask can be removed, cleaned and replaced in time. The spacer 26 prevents the support spring 3 and the elastic mesh 29 from wearing each other and producing abnormal noise. The elastic mesh 29 and elastic rubber plate 33 connect the support spring 3 and have lateral elastic tension and support functions. They also assist the support spring 3 in performing its independent support function, so as to achieve more effective support for different parts of the human body. Water is circulated from the low-pressure tank 35 to the high-pressure tank 34 through the cooperation of the liquid circulation pump 38 and the solenoid valve 11. The high-pressure tank 34 is kept at constant pressure through the cooperation of the gas booster pump 39 and the solenoid valve 11. Through the cooperation of the high-pressure liquid pipe 40 and the solenoid valve 11, high-pressure water is injected into the pressure rod AI18 or AI19. The support rod 7 causes the rubber support 17 to rise, reducing the distance between it and the septum 26. This reduces the distance the spring pad supporting a certain part of the body needs to descend under heavier pressure until it stops, thus adjusting the height of the spring pad as it descends under pressure. When the injected high-pressure water continues to increase rapidly, the support rod 7 causes the rubber support 17 to quickly impact the septum 26, causing the adjusting part of the spring pad to vibrate or compress the body. The switching frequency between the solenoid valve 11 on the liquid inlet 9 and the solenoid valve 11 on the outlet 10 is controlled to achieve the purpose of vibration or massage on the body. Through the cooperation of the high-pressure gas pipe 41 and the solenoid valve 11, high-pressure water is injected into the pressure rod AI18 or AI19. After high-pressure gas is injected into 18 or AⅡ19, the support rod 7 drives the rubber support 17 to rise rapidly. Because the gas flow rate is faster than the liquid flow rate, the support rod 7 drives the rubber support 17 to hit the diaphragm 26 more quickly, so that the adjustment part of the spring pad has a more obvious vibration or compression effect on the human body. By controlling the switching frequency between the solenoid valve 11 on the gas inlet 9 and the solenoid valve 11 on the outlet 10, the spring pad can achieve a better vibration or massage effect on the human body. When the diaphragm 26 is hit and raised by the rubber support 17, the pull rope A is released through the buffer spring 14. The tension of 15 can reduce the downward stretching of the pad 26, which is beneficial to the vibration or massage function. Through the lateral connection and elastic stretching of the elastic mesh 29 and elastic rubber plate 32 to the support spring 3, the independent support function of the support spring 3 when rising or falling can be improved. This is beneficial to the balanced support of the spring pad for various curves of the human body, so as to eliminate fatigue and achieve better health rest. Similar to the above adjustment structure and method, after water is injected into the pressure rods BⅠ24 and BⅡ25, the support rod 7 and roller 22 drive the pull rope B 23 to rise gradually. The pull rope B 23 drives the bracket 2 to rise. The support elasticity of the spring 3 after compression increases, and the user's body feels an increase in the hardness of the spring pad. Conversely, after water is released from the pressure rods BⅠ24 and BⅡ25, the hardness becomes softer, thus achieving the purpose of adjusting the softness or hardness of the spring pad. Through the setting of multiple pressure rods A 16,This system allows for adjustment of the spring pad's height and vibration intensity in different areas. Multiple pressure rods B 21 allow for adjustment of the spring pad's firmness in different areas. The touchscreen display 45 and main control unit 43 enable real-time adjustment of the spring pad during use.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
