[0033] In the following description, a large number of details are explored to provide a more thorough explanation of the embodiments of the present utility model. However, it is obvious to those skilled in the art that the embodiments of the present utility model can be implemented without these specific details.

[0034] As Figures 1-8 shown, the built-in tent pump in the present application includes a power module 1 and a pump body 2 built into the air column of an inflatable tent. An installation groove 21 is provided on the side wall of the pump body 2; the pump body 2 is built into the air column of the inflatable tent, and the connection between the pump body 2 and the air column of the inflatable tent is sealed through a waterproof structure to play a waterproof role.

[0035] A metal electrode 15 is provided on the power module 1, and the metal electrode 15 is connected to the power module 1; a metal contact 211 is provided in the installation groove 21, and the metal contact 211 is connected to the pump body 2;

[0036] When the power module 1 is installed in the installation groove 21, the metal contact 211 is connected to the metal electrode 15 to supply power to the pump body 2.

[0037] Among them, the metal electrode 15 is formed by bending a metal sheet into a groove shape. When the power module 1 is installed in the installation groove 21, the metal contact 211 is inserted into the groove to make the connection between the metal contact 211 and the metal electrode 15 more stable.

[0038] The power module 1 includes a power housing 11, a built-in battery 13, a control circuit board 12 for controlling power supply control and charging management of the built-in battery based on a control signal, and a control button 14 for inputting a control signal;

[0042] The nozzle 25 is arranged at the end of the pump housing 22;

[0043] The air pressure acquisition end of the air pressure sensor switch 24 is connected to the exhaust end of the diaphragm pump 23 through a silica gel hose. The switch control end of the air pressure sensor switch 24 and the switch control end of the diaphragm pump 23 are both connected to the metal contact 211 to be connected to the control circuit board 12. The air pressure sensor switch 24 is used to turn off the diaphragm pump 23 when the inflation air pressure is greater than a preset first threshold value.

[0045] A one-way valve 251 is provided inside the air nozzle 25.

[0046] The diaphragm pump 23 pumps air into the inflatable tent along the air nozzle 25, thereby inflating the inflatable tent. During the inflation process, the air pressure sensor switch 24 collects the air pressure at the exhaust end of the diaphragm pump 23 (since the exhaust end of the diaphragm pump 23 is connected to the inside of the inflatable tent at this time, the air pressure at the exhaust end of the diaphragm pump 23 is the air pressure inside the tent). When the air pressure reaches the preset first threshold value, it automatically turns off and stops inflation to avoid over-inflating the tent.

[0047] A connecting ring 252 made of PVC or TPU material is provided on the air nozzle 25, and the connecting ring 252 is welded to the air column of the inflatable tent. In this application, the air nozzle 25 is welded and fixed to the air column of the inflatable tent through the connecting ring 252 made of PVC or TPU material, and the air nozzle 25 is fixed in the pump body 2, so the built-in of the air pump is realized.

[0048] An air inlet 221 is provided at the bottom of the installation groove 21. Air enters the installation groove 21 from the gap between the power supply module 1 and the installation groove 21 and enters the pump housing 22 from the air inlet 221.

[0049] In addition, a pressure relief valve 26 is provided inside the pump body 2 and is used to open when the inflation air pressure is greater than a preset second threshold value, further preventing over-inflation of the tent.

[0050] The built-in tent pump of the present utility model includes a power supply module and a pump body built in the air column of the inflatable tent. An installation groove is provided on the side wall of the pump body; a metal electrode is provided on the power supply module and is connected to the power supply module; a metal contact is provided in the installation groove and is connected to the pump body; when the power supply module is installed in the installation groove, the metal contact is connected to the metal electrode to supply power to the pump body.
