Sleeping pad with fast-inflation and deflation air nozzle

A sleeping pad, comprising:

• a sleeping pad body with an air nozzle;
• wherein a three-layer sponge pad is arranged in the sleeping pad body;
• a middle layer of the three-layer sponge pad is provided with a plurality of holes;
• the air nozzle comprises a base, an air channel and a sealing cover;
• the sealing cover is detachably and sealedly inserted into the air channel;
• and the air channel is detachably and sealedly inserted into the base;
• a support is integrally formed inside the air channel;
• a first gasket groove is arranged on a top of one side of the support;
• a second gasket groove is arranged on a bottom of the other side of the support;
• a bottom of the first gasket groove is provided with a first vent hole penetrating the support;
• a deflating gasket is fixedly provided in the first gasket groove;
• the deflating gasket is attached to the first vent hole of the first gasket groove;
• a top of the second gasket groove is provided with a second vent hole penetrating the support;
• an inflating gasket is fixedly provided in the second gasket groove;
• the inflating gasket is attached to the second vent hole of the second gasket groove;
• and the deflating gasket and the inflating gasket are both made of a silicone material;
• and
• a switch baffle plate is rotatably arranged on the support;
• the switch baffle plate comprises a first baffle plate and a second baffle plate;
• the first baffle plate is connected to the second baffle plate;
• the first baffle plate is arranged above the deflating gasket;
• the second baffle plate is arranged below the inflating gasket;
• the switch baffle plate is configured to be driven to rotate with respect to the support to achieve switch between an inflation mode and a deflation mode;
• when the switch baffle plate is in the inflation mode, the first baffle plate is directly above the deflating gasket and presses against the deflating gasket, and the second baffle plate is staggered from the inflating gasket and external air is blown onto the inflating gasket, such that the inflating gasket is deformed to expose the second vent hole, and the external air enters the sleeping pad body through the second vent hole;
• and when the switch baffle plate is in the deflation mode, the first baffle plate is staggered from the deflating gasket, and the second baffle plate is directly below the inflating gasket and abuts against the deflating gasket, such that air in the sleeping pad body is blown onto the deflating gasket, and the deflating gasket is deformed to expose the first vent hole, such that the air in the sleeping pad body is discharged to outside through the first vent hole.
