The air pump control box according to claim 6, wherein the connection pipe fitting is further provided with an air pressure detection pipe, the air pressure detection pipe is communicated with the air release chamber, a pressure sensor is arranged in the air pressure detection pipe, and the pressure sensor is associated with on-off control of at least one of the first electromagnet assembly and the second electromagnet assembly, so that feedback control of on-off control of the first electromagnet assembly and the second electromagnet assembly is realized through the pressure sensor.

9. The air pump control box according to claim 1, wherein an explosion-proof air receiving tube is disposed on the housing, a tube is disposed in the explosion-proof air receiving tube, the tube is communicated with the cavity, an explosion-proof membrane is disposed in the tube, and when the air pressure in the cavity is greater than a predetermined value, the explosion-proof membrane is pushed to burst out of the tube to open the explosion-proof air receiving tube.

10. A mattress with adjustable softness and hardness is characterized by comprising a supporting layer, an air bag layer and a control system, wherein the air bag layer is arranged on the supporting layer, an air cavity is arranged in the air bag layer, the control system comprises an air pump, an air pump control box and an air pipe, the air pump is connected to the air pump control box, the air pump control box is communicated with the air cavity in the air bag layer through the air pipe, the air pump inflates or deflates the air cavity through the air pump control box and the air pipe, and the air pump control box is the air pump control box according to any one of claims 1 to 9.
