[0029] Working principle:

[0030] When the hardness of the mattress needs to be adjusted during use, the mattress power is turned on, and then the transmission mechanism 408 is controlled by the control switch 409 to operate. The operation of the transmission mechanism 408 will drive each worm 407 to rotate, and the worm 407 will drive the threaded rod 405 to rotate through the worm wheel 406. The rotation of the threaded rod 405 can drive the lifting block 403 to rise and fall. The lifting of the lifting block 403 will adjust the elastic force of the spring 3, thereby realizing the adjustment of the hardness of the mattress.
