[0031] In order to make the invention purposes, technical solutions and technical effects more clear and explicit, the invention is further described below in combination with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the invention and do not limit the invention.

[0032] Referring to Figs. 1-4, an automatically controlled air pump 100 includes a pump shell 110 and pump covers 120a and a control panel 120b arranged at opposite ends of the pump shell 110. The pump shell 110 is internally provided with a motor chamber 130, a motor 140, a printed circuit board 150, and an air pressure detector 160. The motor chamber 130 is arranged in the middle of the inner cavity of the pump shell 110, with a first end 131 of the motor chamber 130 being close to the pump cover 120a, and the motor 140 being accommodated in the motor chamber 130. The printed circuit board 150 is arranged outside the motor chamber 130, preferably close to the pump cover 120a. The printed circuit board 150 is provided with an IC control chip (not shown) and the air pressure detector 160. The printed circuit board 150 is electrically connected to the motor 140, and the IC control chip controls the start or stop of the motor 140. The air pump 100 is used for inflating an inflatable product 300, such as an outdoor tent, an inflatable bed, an inflatable jumping bed, an inflatable castle, etc. The air pressure detector 160 detects the air pressure in the inflation cavity of the inflatable product 300. When the detected air pressure value exceeds the upper limit of the preset value, the IC control chip on the printed circuit board 150 controls the motor 140 to stop working, so as to prevent the air pressure from being too large and damaging the inflatable product 300. When the detected air pressure value is less than the lower limit of the preset value, the IC control chip on the printed circuit board 150 controls the motor 140 to start, and continues to inflate the inflatable product 300, so as to automatically control the air pressure in the inflatable product 300 to always maintain a moderate state, and maintain normal use.

[0033] The air pump 100 includes two sets of power supply systems, i.e., an internal battery 170 and an external power supply. When the air pump is used for inflating the inflatable product, the battery power is sufficient, and the battery power supply is preferred. When the battery 170 is out of power, the external power supply or power bank can be used to supply power to the printed circuit board 150 and the motor 140, and charge the battery 170 at the same time.

[0034] Specifically, a pair of batteries 170 are arranged in the pump shell 110 and are respectively arranged on both sides of the motor chamber 130. The batteries 170 supply power to the printed circuit board 150 and the motor 140.

[0035] The pump shell 110 or the control panel 120b is also provided with a DC interface 121, a USB external charging interface 122 and a type-C interface 123. The control panel 120b is electrically connected to the printed circuit board 150. The DC interface 121 is used to connect an external power supply to supply power to the printed circuit board 150 and the motor 140, and the type-C interface 123 is used to connect other devices such as a power bank. The charging interface 122 is electrically connected to a mobile phone, a flashlight and the like for charging, thereby expanding the function of the air pump as a backup power supply, facilitating emergency use when the mobile phone and flashlight power is depleted when outdoors.

[0036] The printed circuit board 150 is also electrically connected to a lamp panel 151, and the lamp panel 151 is provided with an LED lamp 152, which is used as an illuminating lamp and an SOS warning lamp. The lamp panel 151 is preferably installed close to the pump cover 120a inside the pump shell 110. The pump cover 120a is provided with an LED lamp switch button 153, and the switch button 153 has three control modes. The LED lamp is turned on or off by rotating the switch button 153. After the LED lamp is turned on, the light brightness is adjusted by tapping, and the LED lamp is flashed by long pressing, and is changed to an SOS warning lamp mode. The setting of the lamp panel 151 expands the function of the air pump 100, so that it can be used as an illuminating lamp or a warning lamp. When users go outdoors, especially camping, it is inconvenient to carry too many items. The air pump 100 has the function of an illuminating lamp, realizes one thing with multiple uses, and is very convenient. When an emergency occurs outdoors and rescue is needed, the warning lamp can be turned on for alarm, indication to rescuers, etc.

[0037] The control panel 120b is also provided with function buttons such as on / off keys 125 for turning on and off, respectively, and up / down value keys 126 and 127 for setting the upper and lower limits of the air pressure value. The control panel 120b is also provided with a display screen 128 for displaying the air pressure value detected by the air pressure detector 160.

[0038] The air pump 100 is also provided with a handle 170 for easy carrying of the air pump 100. The air pump 100 is pivotally connected to the pump cover 120a or the control panel 120b, and is turned away from the pump cover 120a or the control panel 120b when in use, and is attached to the pump cover 120a or the control panel 120b when not in use.

[0039] Referring to FIG. 5-8, the air pump 100 is a built-in and external dual-purpose air pump, which can be built-in in the inflatable product 300 to inflate or deflate it, and can be external to the inflatable product 300 to inflate or deflate it. When it is a built-in air pump, the inflatable product 300 is provided with an air chamber 200, and the air pump 100 is placed in the air chamber 200. Specifically, the air chamber 200 is provided on the outer wall of the inflatable product 300, including a chamber cover 210 and a chamber body 220, the chamber cover 210 exposes the outer wall surface of the inflatable product 300, and the chamber body 220 is located inside the inflatable product 300. The air chamber 200 is provided with a ventilation structure matched with the air pump 100 to realize inflation or deflation. Specifically, the bottom of the air chamber 200 is inwardly recessed to form a matching cylinder 230, and the motor chamber 130 is provided with a first plug-in cylinder 131 penetrating through the pump cover 120a, and the matching cylinder 230 is inserted into the first plug-in cylinder 131. The matching cylinder 230 is provided with a mounting cylinder 231 and a first sealing gasket 232, the first sealing gasket 232 has a plug-in part 2321 and a sealing part 2322, the plug-in part 2321 is inserted into the mounting cylinder 231 and is in sliding fit with it, and the sealing part 2322 is in sealing connection with the matching cylinder 230. The first sealing gasket 232 is also provided with a second sealing gasket 233, which is slidingly inserted into the plug-in part 2321 and is in sliding fit with it. The plug-in part 2321 communicates the air chamber 200 and the inner cavity of the pump shell 110. The matching cylinder 230 is also provided with a limiting piece 234 opposite to the sealing piece, and a spring 235 is arranged between the limiting piece 234 and the first sealing gasket 232 to elastically abut the first sealing gasket 232 and the limiting piece 234. When the air pump 100 inflates the inflatable product 300, the air pressure in the air chamber 200 is greater than the air pressure in the cavity of the inflatable product 300, thereby pushing the second sealing gasket 233 to open the plug-in part 2321, that is, to make the inner cavity of the pump shell 110, the inner cavity of the air chamber 200 and the inner cavity of the inflatable product 300 communicate, thereby enabling the inflatable product 300 to be inflated. When the air pressure detector 160 detects that the air pressure value in the inflatable product 300 reaches the set upper limit, the motor 140 is controlled to stop working by the IC control chip, and then the air pressure in the inner cavity of the pump shell 100, the air chamber 200 and the inflatable product 300 gradually equalizes or approaches equalization, and the air pressure pushes the second sealing gasket 233 to reset, thereby sealing the inner cavity of the inflatable product 300.

[0040] Preferably, the limiting member 234 is provided with a through hole 2341 matched with the air pressure detector 160, and a sealing plug is arranged in the through hole 2341. When the air pump 100 is installed in the inflating chamber 200 in the state of inflating the inflating product, the air pressure detector 160 is inserted into the through hole 2341 and pushes away the sealing plug, so that the through hole 2341 is communicated with the inner cavity of the inflating product 300, thereby protecting the air pressure detector 160 and facilitating the detection of the air pressure in the inner cavity of the inflating product 300.

[0041] The chamber cover 210 is provided with an air hole 211 and a sealing gasket 212 matched with the air hole 211. When the air pump 100 is placed in the inflating chamber 200 to inflate the inflating product 300, the air pressure in the inflating chamber 200 is greater than the external air pressure, the sealing gasket 212 is opened, and the external air enters the inflating chamber 200 through the air hole 211 to inflate the inflating product 300. When the air pump 100 stops working, the external air pressure is the same as the air pressure in the inflating chamber 200, and the sealing gasket 212 covers the air hole 211, effectively preventing rainwater, dust and the like from entering the inflating chamber 200.

[0042] The air pump 100 also has the function of deflating the inflating product 300. Specifically, referring to FIG. 9, when deflation is needed, the chamber cover 210 of the inflating chamber 200 is opened, the air pump 100 is taken out, and the air pump 100 is inverted, that is, the first plug-in barrel of the air pump 100 is close to the chamber cover 210. The air pump 100 is provided with a second plug-in barrel 132 on the side opposite to the first plug-in barrel 131, that is, the pump cover 120a, and the second plug-in barrel 132 is provided with a pushing part 133 in the middle. When the air pump 100 is inverted, the second plug-in barrel 132 is matched and inserted into the matching barrel 230, the pushing part 133 pushes the first sealing gasket 232 through the mounting barrel 231, opens the sealed connection between the first sealing gasket 232 and the matching barrel 230, so that the inner cavity of the inflating product 300 is communicated with the inflating chamber 200, the motor 140 works, the gas in the inflating product 300 is extracted and discharged to the outside, and deflation is realized. In order to facilitate operation, it is preferred that the pump cover 120a is also provided with an on-off key, which facilitates the start or stop of the motor 140 when the air pump 100 is inverted.

[0043] Therefore, the air pump 100 has the functions of inflating and deflating the inflating product 300. The conversion of the inflation and deflation functions only needs to invert the direction of the air pump 100 in the inflating chamber 200, which is simple and convenient to operate.

[0044] In addition, the air pump 100 can inflate and deflate the inflatable product 300 without the air chamber 200, and can also inflate and deflate other inflatable products without the air chamber 200. At this time, only an air pipe is needed to connect the first plug-in barrel 131 or the second plug-in barrel 132 of the air pump 100 and the product to be inflated or deflated. The implementation principle and basic structure are well-known technologies that should be known by those skilled in the art, and will not be described here.

[0045] The motor 140 is a high-speed brushless DC motor 140 with the characteristics of large flow, high pressure, and large capacity, and its efficiency can reach 2-3 PSA pressure, 5000-10000 mA battery capacity, and 600-800 L / min flow. Compared with conventional motors, its performance only has large flow, small pressure, or large pressure, small flow, and cannot meet the requirements of outdoor tents, trampolines, and other inflatable products.

[0046] The above is a further detailed description of the present application in combination with specific preferred embodiments, and the specific implementation of the present application should not be limited to these descriptions. For those skilled in the art to which the present application belongs, the architecture can be flexible and variable without departing from the concept of the present application, and a series of products can be derived. Any simple deduction or replacement should be considered as falling within the scope of the patent protection determined by the submitted claims.
