Examples
As shown in fig. 1 to 5, an internal and external air pump for a tent in the present application includes an external pump 1 and an internal pump 2 built in the tent;
the built-in pump 2 comprises a first shell 21 and a diaphragm pump 22 arranged on the first shell 21, wherein two ends of the first shell 21 are respectively an air inlet end and an air outlet end;
the external pump 1 includes a second housing 11, a battery 111 and a blower unit 112 provided in the second housing 11; the second housing 11 is provided with an air inlet 113, an air outlet 114 and a contact spring 115 connected with the battery 111; the blower unit 112 is connected to the battery 111; wherein the blower unit 112 includes a brushless motor 1121 and blades provided on an output shaft of the brushless motor 1121.
The cooperation working principle of the external pump 1 and the internal pump 2 is as follows: the blower unit 112 is driven by the brushless motor 1121, and has an advantage of a high inflation speed. But the blower unit 112 driven by the brushless motor 1121 cannot continue to blow air in a high air pressure state. Therefore, at this time, the diaphragm pump 22 is operated to continue to blow air, thereby completely swelling the inflatable tent.
The external pump 1 can be used as an independent product, and the external pump 1 is provided with three gears to adapt to various use scenes, and in addition, the internal of the external pump 1 is provided with an air pressure sensor switch to collect the inflation air pressure and automatically close when the inflation air pressure is greater than a threshold value so as to prevent overcharging.
The first housing 21 is provided with a mounting groove 211 with a shape matched with that of the external pump 1, and an opposite interface 2311 and a metal contact 2111 connected with the diaphragm pump 22 are arranged in the mounting groove 211;

When the external pump 1 is matched, the external pump 1 is inserted into the mounting groove 211, so that the metal contact 2111 can be just connected with the contact spring plate 115, and the internal pump 2 can be powered by the external pump 1 because of the internal battery 111 of the external pump 1. Further, the air outlet 114 of the second housing 11 is connected to the docking 2311 to form an air flow path, and air is introduced from the air inlet end of the first housing 21, driven by the diaphragm pump 22 or the blower unit 112, and blown into the inside of the inflatable tent from the air outlet end of the air inlet end of the first housing 21.
Specifically, the second housing 11 is provided with a fastening groove 118, the mounting groove 211 is provided with an elastic fastening 2112, and the elastic fastening 2112 is matched with the fastening groove 118 so that the external pump 1 can be detachably mounted in the mounting groove 211;
the first housing 21 is further provided with a buckle button 2113 for disengaging the elastic buckle 2112 from the buckle slot 118, and the buckle button 2113 is connected with the elastic buckle 2112. External pump 1 and built-in pump 2 in this application can dismantle the connection through the buckle to guarantee the stability that external pump 1 and built-in pump 2 connect.
The exhaust end of the first housing 21 is provided with an air tap 212, and a first check valve 2121 is disposed in the air tap 212. The first check valve 2121 serves to prevent leakage of gas inside the inflatable tent.
The exhaust port 114 of the second housing 11 is provided with a second one-way valve 1141. Since the external pump 1 can be used alone, the second check valve 1141 is provided at the exhaust port 114 of the second housing 11 to prevent gas leakage when the external pump 1 is used alone.
In an embodiment of the present application, the external pump 1 further includes a PCB 116 disposed in the second housing 11 and used for controlling the blower unit 112 and the diaphragm pump 22, where the PCB 116 is connected to the blower unit 112, the battery 111 and the contact spring 115;
the second housing 11 is provided with a plurality of control keys 117, and the plurality of control keys 117 are connected with the PCB 116 to input control signals.
The contact spring 115 and the metal contact 2111 are used for transmitting not only a power signal but also a control signal. The operation states of the brushless motor 1121 and the diaphragm pump 22 can be controlled by inputting control instructions through the control keys 117.

The plug-in sealing assembly 231 is inserted into the exhaust port 114 of the second housing 11, so that better sealing performance and stronger connection stability can be ensured.
The connecting piece 23 is further provided with a high-pressure input port 232 for inputting a high-pressure air flow generated by the diaphragm pump 22. Since the blower unit 112 cannot continue to blow air after the air pressure inside the inflatable tent increases, it is difficult for the diaphragm pump 22 to blow air through the blower unit 112. Therefore, the side surface of the connecting piece 23 is provided with a high-pressure input port 232, and air blown by the diaphragm pump 22 directly passes through the high-pressure input port 232 to reach the air tap 212 and enters the inside of the inflatable tent.
The internal and external air pump for the tent comprises an external pump and an internal pump arranged in the tent, wherein the external pump is arranged in a mounting groove of the internal pump, and when the tent is mounted, the external pump is connected with a metal contact of the internal pump through a contact spring plate, so that power is supplied to the internal pump. The built-in pump is arranged inside the inflatable tent and is powered through the external pump. The external pump is internally provided with the air blowing unit, and the air blowing unit is driven by the brushless motor, so that air flow can be quickly blown into the inflatable tent in a short time. When the air blowing unit cannot fully bulge the inflatable tent, the diaphragm pump inside the built-in pump works to fully bulge the inflatable tent. In addition, the external pump can be taken down for independent use, and can be flexibly used in various scenes while being convenient to charge.
The above embodiments are merely illustrative of the principles of the present application and its effectiveness and are not intended to limit the present application. Modifications and variations may be made to the above-described embodiments by those of ordinary skill in the art without departing from the spirit and scope of the present application. It is therefore contemplated that the appended claims will cover all such equivalent modifications and changes as fall within the true spirit and scope of the disclosure.
