Description

Technical Field

[0001] The utility model relates to the field of tent air pumps, in particular to a built-in pump for an inflatable tent. Background Art

[0002] A tent air pump, also known as an air pump or inflator, is an inflatable tool that works through the operation of a motor. Its operating principle is based on atmospheric pressure. When the motor is running, the valve of the connecting valve is opened by atmospheric pressure when pumping air, allowing gas to enter the cylinder. When inflating an object such as a tent, the valve is closed by the air pressure within the cylinder, allowing gas to enter the target object. This technology enables the tent air pump to quickly provide the required air pressure for tents and other inflatable objects, allowing for rapid erection.

[0003] Currently, most tent air pumps on the market only offer a single inflation function. While this functionality is sufficient for general camping and emergency sheltering, the increasing diversity and sophistication of outdoor activities has led to increasing demands for more functional tent air pumps. The drawbacks of existing air pumps, such as the need to vent the air inside the tent when storing it, are becoming increasingly apparent. However, most existing tent air pumps only inflate and cannot directly vent the air, making the storage process relatively cumbersome.

[0004] Therefore, it is necessary to propose a built-in pump for an inflatable tent to solve the above problems. Utility Model Content

[0041] In addition, if the air pressure is too high during deflation, some of the gas will enter the conical hole 21 from the inside of the rubber-coated frame 17, and then the high-pressure gas in the conical hole 21 will push the first silicone sealing head 31 to move, and the third return spring 30 will be compressed.
