[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] like Figures 1-3 As shown, the automatic tent inflation pump provided in this invention includes a housing 1 and a low-pressure pump 2, a high-pressure pump 3, a one-way air valve 4, an air pressure sensor, and a control circuit disposed inside the housing 1.

[0040] The housing 1 includes an air inlet 11 and an exhaust outlet 12. The housing 1 is embedded in the tent wall. The air inlet 11 is located outside the tent, and the exhaust outlet 12 is located inside the tent. The one-way air valve 4 is located at the exhaust outlet 12. The automatic tent inflation pump in this application is installed as an inflation accessory on the inflatable tent.

[0041] The low-pressure pump 2 is used to pump air from the air inlet 11 into the interior of the housing 1, and into the tent through the one-way air valve 4;

[0042] The air pressure sensor is connected to the control circuit, and the control circuit is connected to the low-pressure pump 2 and the high-pressure pump 3. The air pressure sensor is used to detect the air pressure value inside the tent, and the control circuit is used to turn off the low-pressure pump 2 and turn on the high-pressure pump 3 when the air pressure value inside the tent reaches a preset threshold.

[0043] The air inlet of the high-pressure pump 3 is located inside the tent. The high-pressure pump 3 is used to continue pumping air from the air inlet 11 into the interior of the housing 1 when the low-pressure pump 2 is turned off, and into the interior of the tent through the air inlet.

[0044] Because the low-pressure pump 2 pumps in a larger airflow, inflating the tent using the low-pressure pump 2 in the early stages can effectively improve inflation efficiency. When the air pressure inside the tent reaches a preset threshold (e.g., 2000 Pa), the control circuit switches the inflation pump to the high-pressure pump 3 to continue inflation until the tent is fully inflated. Therefore, this application can both improve inflation efficiency and ensure the inflation pressure inside the tent.

[0045] The low-pressure pump 2 includes a pump casing 21 and a motor 22 and vortex blades 23 disposed inside the pump casing 21.

[0046] The motor 22 is connected with the control circuit;

[0047] The pump shell 21 is provided with an air inlet 211 and an air outlet 212, the vortex blade 23 is arranged on the output shaft of the motor 22, and the vortex blade 23 is used for pumping air from the air inlet 211 into the inside of the pump shell and discharging the air through the air outlet 212.

[0048] The air outlet 212 is directed to the one-way air valve 4.

[0049] The low-pressure pump 2 in the application pumps air by using the motor 22 and the vortex blade 23. Since the tent automatic inflation pump in the application is arranged on the inflatable tent as an inflation accessory, in order to prevent air leakage, the one-way air valve 4 is arranged.

[0050] The high-pressure pump 3 in the application is a diaphragm pump, and therefore a valve does not need to be arranged at the corresponding position of the high-pressure pump 3.

[0051] The one-way air valve 4 comprises a valve seat 41 and a valve core 42.

[0052] The valve seat 41 is arranged at the air outlet 12, and the valve seat 41 comprises a gas-permeable hole and a sliding hole.

[0053] The main body of the valve core 42 is arranged in the sliding hole, and the bottom of the valve core 42 is provided with a diaphragm 421 used for plugging the air outlet 12.

[0054] During the inflation process of the low-pressure pump 2, the air pressure in the shell 1 is greater than the air pressure inside the tent, and therefore the diaphragm 421 moves towards the tent, at this time, the diaphragm 421 is separated from the air outlet 12, and air enters the inside of the tent from the surrounding gaps. After the inflation is completed, the air pressure in the shell 1 is less than the air pressure inside the tent, the diaphragm 421 moves towards the shell 1, and is attached to the valve seat 41, thereby sealing the air outlet 12.

[0055] The shell 1 is further provided with a knob 13, and the inside of the shell 1 is further provided with an air exhaust assembly used for lifting the one-way air valve 4, the knob 13 is connected with the air exhaust assembly through a transmission assembly, and when the knob 13 is rotated to the air exhaust position, the air exhaust assembly lifts the one-way air valve 4.

[0056] The air exhaust assembly comprises a sliding channel 14 arranged in the inside of the shell 1 and a lifting block 15 sliding in the sliding channel 14.

[0057] The bottom of the top block 15 is provided with an inclined surface, and the top of the valve core 42 is provided with an inclined rib corresponding to the inclined surface. When the top block 15 slides to the target position of the sliding channel 14, the valve core 42 is pushed open by the inclined surface so that the diaphragm 421 is separated from the exhaust port 12.

[0058] The transmission assembly includes a turntable 131 and a transmission rod 16 disposed at the bottom of the knob 13;

[0059] A drive shaft 132 is provided at the non-center position of the bottom of the turntable 131. Two parallel crossbars 161 are provided at the top of the drive rod 16. A cam 162 for pushing the top block 15 is provided at the bottom of the drive rod 16. The drive shaft 132 is clamped between the two parallel crossbars 161.

[0060] One end of the top block 15 contacts the cam 162, and one end of the top block 15 is connected to the sliding channel 14 via a spring 17.

[0061] The knob 13 is also connected to the control circuit, which is also used to control the low-pressure pump 2 to extract the gas inside the tent when the knob 13 is turned to the exhaust position.

[0062] The automatic air pump in this application also includes a deflation function. When the knob 13 is selected to the deflation position, the one-way air valve 4 is opened via the transmission rod 16, allowing air to be expelled from inside the tent. Furthermore, to further improve deflation efficiency, the motor 22 is driven to reverse, thereby extracting air and improving deflation efficiency.

[0063] Figure 4 A pneumatic circuit diagram for the low-pressure pump inflation of the automatic air pump in one embodiment of this application is shown below. Figure 4 As shown, when the low-pressure pump is working, it draws air into the housing and then into the pump casing. Under the action of the vortex blades, the airflow is pumped into the one-way air valve.

[0064] Figure 5 This is a gas path diagram for the low-pressure pump venting of the automatic air pump in one embodiment of this application, as shown below. Figure 5 As shown, when venting, the one-way valve is opened, and gas flows into the housing from the one-way valve. At the same time, the motor in the low-pressure pump rotates in the opposite direction, continuously drawing gas out of the tent and expelling it from the exhaust port.

[0065] The tent automatic inflator pump of the present application comprises a shell and a low-pressure pump, a high-pressure pump, a one-way air valve, an air pressure sensor and a control circuit arranged inside the shell; the shell comprises an air inlet and an air outlet, the shell is embedded on the tent wall, the air inlet is located outside the tent, the air outlet is located inside the tent, and the one-way air valve is arranged at the air outlet; the low-pressure pump is used for pumping air from the air inlet into the inside of the shell and into the inside of the tent through the one-way air valve; the air pressure sensor is connected with the control circuit, the control circuit is connected with the low-pressure pump and the high-pressure pump, the air pressure sensor is used for detecting the air pressure value inside the tent, and the control circuit is used for closing the low-pressure pump and opening the high-pressure pump when the air pressure value inside the tent reaches a preset threshold value; the air inlet of the high-pressure pump is located inside the tent, and the high-pressure pump is used for continuing to pump air from the air inlet into the inside of the shell and into the inside of the tent through the air inlet when the low-pressure pump is closed. The present application simultaneously sets the high-pressure pump and the low-pressure pump, uses the low-pressure pump to improve the inflation speed at the beginning of inflation, uses the high-pressure pump to continue inflation after the air pressure reaches a certain value, and makes the tent completely inflated. The inflation effect of the present application is better.
