The key operation of the user specifically comprises starting operation, closing operation, setting operation, pause operation and the like; the corresponding signals include a start signal, a close signal, a set signal, a pause signal, and the like. The key module 200 may be a physical key or a virtual key, and the number, shape, size, and the like of the keys may be set according to the needs of the actual application scenario. In practical applications, the key module 200 may include a plurality of physical keys, and different physical keys generate different signals when being pressed, for example, a start key, a close key, a set/adjust key, a confirm key, and the like may be set. Similarly, the key module 200 may include virtual keys, i.e., virtual keys arranged by a touch component, e.g., a plurality of virtual keys displayed by a touch screen, wherein different virtual keys generate different signals when touched (pressed).

The display module 100 may be specifically an LED (Light-Emitting Diode) display screen, which may specifically display data pushed by the controller 300, for example, display the initial air pressure of the inflatable object, and display the current remaining power detected by the controller 300. Further, in order to optimize the structure of the entire electric inflator, the display module 100 may be miniaturized, and the display module 100 may display different information periodically, for example, the initial air pressure and the current remaining capacity of the inflation subject are displayed alternately at a period of 3 seconds.

In practical application, when a user needs to inflate an inflatable object, the user presses a start key on the key module 200, the key module 200 responds to the start operation to generate a start signal and sends the start signal to the controller 300, the controller 300 wakes up the display module 100 and the inflatable assembly 400 after receiving the start signal, and the display module 100 and the inflatable assembly 400 are powered on to wake up and start working; meanwhile, the controller 300 detects the current remaining power, the inflation assembly 400 detects the initial air pressure of the inflation object, sends the initial air pressure to the controller 300, and the controller 300 sends the current remaining power and the initial air pressure to the display module 100 for displaying, at this time, the display module 100 displays information that the current remaining power is (for example, 35%), the initial air pressure is (for example, 1.2 atmospheres), and the like. After browsing the information displayed by the display module 100, the user may determine, based on his own experience, whether the current remaining power is sufficient to inflate the inflatable object to the target air pressure, for example, if the target air pressure is 2.2 atmospheres, and the user determines, based on his own experience, that 35% of the remaining power can support the current inflation task, the user presses an inflation start button on the key module 200, and the controller 300 controls the inflation component 400 to start working to inflate the inflatable object; if the target air pressure is 2.5 atmospheric pressures, the user judges that 35% of residual electric quantity cannot support the inflation task based on own experience, and the user can select to charge the electric inflator pump first and then use the electric inflator pump, so that convenience is brought to the user.

The electric inflator of the present application includes a display module 100, a key module 200, a controller 300, and an inflation assembly 400; the key module 200 responds to the power-on operation and sends a power-on signal to the controller 300, the controller 300 responds to the power-on signal to wake up the display module 100 and the inflation assembly 400, the inflation assembly 400 detects the initial air pressure of the inflation object and sends the initial air pressure of the inflation object to the controller 300, the controller 300 detects the current residual electric quantity, and the initial air pressure of the inflation object and the current residual electric quantity are pushed to the display module 100 to be displayed. Whole electronic pump can detect when the power-on starts and aerify the initial atmospheric pressure of object and with current residual capacity and show to support the user to judge whether current electronic pump can accomplish the task of aerifing, it is convenient to bring for the user.

In one embodiment, the key module 200 is further configured to send a setting operation signal to the controller 300 in response to a target air pressure setting operation, and the controller 300 determines the target air pressure according to the setting operation signal, and determines the time consumed for inflation and/or the power consumed for inflation according to the initial air pressure of the inflation object and the target air pressure.

When a user needs to set a target air pressure, the user may operate the key module 200 to generate a corresponding setting operation signal to the controller 300, and the controller 300 adjusts the target air pressure, for example, a +/-key may be provided on the key module 200, when the user presses a + key, a setting operation signal for increasing the target air pressure is generated, the controller 300 increases the target air pressure, when the user presses a-key, a setting operation signal for decreasing the target air pressure is generated, the controller 300 decreases the target air pressure, further, the controller 300 may push the target air pressure set by the user to the display module 100 for display, when the user confirms that the target air pressure is set, the user may press a confirmation key on the key module 200, the key module 200 generates a confirmation signal to the controller 300, and the controller 300 records the target air pressure corresponding to the task. In this embodiment, the user can set a suitable target air pressure through the key module 200, so that the electric inflator pump of the present application can meet the inflation requirements under different application environments.

Since the different initial air pressures and target air pressures have different power consumptions required for inflation, the controller 300 determines the inflation time and/or power consumption required for inflation according to the initial air pressure of the inflation object and the target air pressure. Specifically, the controller 300 may pre-store a correspondence table of initial air pressure-target air pressure-time consumed for inflation-required consumed electric quantity generated according to historical data, and when the time consumed for inflation and/or the electric quantity consumed for inflation needs to be determined, compare the obtained initial air pressure and the obtained target air pressure in the correspondence table to obtain the corresponding time consumed for inflation and/or the electric quantity consumed for inflation. Further, the controller 300 may further analyze a calculation function for the inflation time consumption at different initial air pressures and the target air pressure and a calculation function for the required power consumption at different initial air pressures and the target air pressure based on historical empirical data, and when calculation is required, directly call the calculation function to obtain the corresponding inflation time consumption and/or the required power consumption.

In one embodiment, the inflatable object comprises a plurality of inflatable objects; the controller 300 is further configured to obtain power consumption amounts required by inflation corresponding to different inflatable objects, and push the identifiers of the different inflatable objects and the corresponding required power consumption amounts to the display module 100 for displaying.

In this embodiment, the inflation objects include a plurality of inflation objects, that is, the electric inflator needs to inflate the plurality of inflation objects, specifically, the electric inflator may inflate the plurality of inflation objects simultaneously, or sequentially inflate the plurality of inflation objects, and the initial air pressure and the target air pressure corresponding to different inflation objects may be different, so that the electric energy consumption required by the inflation corresponding to different inflation objects may also be different. In this embodiment, the controller 300 obtains the electric power consumption required for inflation corresponding to different inflatable objects, and pushes the identifiers of the different inflatable objects and the electric power consumption required to be displayed on the display module 100, so that the user can know the electric power consumption required for inflation corresponding to the different inflatable objects at the same time. For example, if a user needs to inflate 4 tires with initial air pressures of 1.9, 2.0, 2.1, and 2.2 atmospheres respectively, and a user of 4 tires sets a unified target air pressure of 2.5 atmospheres, the controller 300 obtains the required consumed electric energy corresponding to the 4 tires based on the initial air pressures of 1.9, 2.0, 2.1, and 2.2 and the target air pressure of 2.5, and pushes the numbers 1, 2, 3, and 4 and the corresponding required consumed electric energy to the display module 100 for display.

In one embodiment, the controller 300 is further configured to compare the current remaining power with the total power consumption required for inflation corresponding to different inflatable objects, and when the current remaining power meets the total power consumption required for inflation, push an inflation permission prompt message to the display module 100 for display; when the current remaining electric quantity does not meet the total electric quantity consumed by the inflation, a prompt message indicating that the target inflation task cannot be completed is pushed to the display module 100 to be displayed.

The controller 300 compares the current remaining power with the total power consumption required by corresponding inflation of different objects, if the current remaining power meets the total power consumption required by inflation, it indicates that the remaining power of the electric inflator can support the task of inflating different inflatable objects to the target air pressure at this time, and pushes an inflation permission prompt message to the display module 100 for display, and the specific display module 100 may display a prompt character of "inflation permission", or directly display an icon of "check mark", and further, the display module 100 may display the character or the icon in green; if the current remaining capacity does not satisfy the total power consumption required by inflation, it indicates that the remaining capacity of the electric inflator pump cannot support the task of inflating different inflatable objects to the target air pressure, i.e., different inflatable objects cannot be inflated to the set target air pressure, at this time, the controller 300 pushes a prompt message indicating that the target inflation task cannot be completed to the display module 100 for display, and the specific display module 100 may display a prompt character indicating that "the remaining capacity is insufficient and the task cannot be completed", or display a prompt character indicating that "! "further, the display module 100 may use red to display the above text or icon.

In one embodiment, the controller 300 is further configured to determine the same maximum pressure for inflating different inflatable objects according to the initial air pressure and the target air pressure corresponding to the different inflatable objects and the current remaining power when the current remaining power does not satisfy the total power consumption required for inflation, and push the same maximum pressure to the display module 100 for display.

Further, when the current remaining power does not satisfy the total power consumption required for inflation, different inflatable objects cannot be inflated to the set target air pressure at this time, and the controller 300 may further calculate to inflate different inflatable objects to the same maximum pressure according to the current remaining power, and push the same maximum pressure to the display module 100 for display. The same maximum pressure here means that the electric inflator can inflate different inflation objects to the same maximum pressure when the electric quantity is exhausted. For example, 4 tires need to be inflated currently, the originally set target pressure is 2.5 atmospheres, the controller 300 determines that the current remaining capacity cannot meet the required capacity for inflating 4 tires to 2.5 atmospheres based on the above calculation process, the controller 300 further calculates that the current remaining capacity at most supports the inflation of 4 tires to 2.2 atmospheres, the controller 300 pushes the hours inflatable to 2.5 atmospheres to the display module 100 for display, and if the user confirms that the inflation is continuously completed, the electric inflator pumps inflate 4 tires to 2.2 atmospheres. Specifically, 4 tires were inflated sequentially to 2.2 atmospheres for each tire.

As shown in FIG. 2, in one embodiment, the electric inflator further comprises a temperature sensor 500 and a pressure sensor 600; the temperature sensor 500 collects and sends an ambient temperature value to the controller 300, the barometric altitude sensor 600 collects and sends an ambient barometric pressure value to the controller 300, the controller 300 determines the maximum safe pressure of the inflatable object according to the ambient temperature value and the ambient barometric pressure value, and the maximum safe pressure is pushed to the display module 100 to be displayed.

The pressure values of the same inflating object to be inflated at different temperatures and different altitudes are different. For example, when the temperature is high, the air in the tire is expanded by heat, and the tire pressure needs to be reduced at the moment for safety; when the temperature is low, the air in the tire is compressed, and at this time, the tire pressure needs to be increased. In high altitude areas, the air is thin, the atmospheric pressure is reduced, and the tire expands outwards, and at the moment, the tire pressure needs to be properly reduced due to safety considerations. For the above reasons, in the present embodiment, the electric inflator further includes a temperature sensor 500 and a pressure sensor 600, and the temperature sensor 500 is configured to collect an ambient temperature and transmit the ambient temperature to the controller 300.

Meanwhile, the relationship among the temperature, the altitude and the suggested inflation pressure is stored in the controller 300, when the temperature sensor 500 and the air pressure sensor 600 measure the temperature and the altitude in the current environment, the temperature and the altitude are fed back to the controller 300, and the controller 300 calls the relational expression among the temperature, the altitude and the suggested inflation pressure, so that the suggested inflation pressure value at any temperature and altitude can be obtained.

The user can know the inflation time required for the inflation object to inflate to the target air pressure value from the beginning of inflation and the expected consumed electric quantity value by operating the inflator. When the air pipe of the inflator is connected to the inflatable object, the air pressure value A of the current inflatable object can be displayed on the display screen. The 'mode key' in selection sets that the inflatable object is to be inflated to the air pressure value B, and then the 'confirmation key' in selection can see the inflation time required by the inflatable object if the inflatable object is inflated from the air pressure value A to the air pressure value B and the expected consumed electric quantity value in the inflation stage on the display screen. The specific correspondence is shown in table 1 below:

table 1 shows the relationship between the inflation time and the voltage and the electric quantity of the electric inflator

As shown in the data in table 1, the initial voltage of the electric inflator at 100% of the electric quantity is 9.25V, and at this time, the electric inflator inflates different objects, and the air pressure required to inflate the objects is 2.4bar. Specifically, firstly, inflating the inflatable object 1 for the first time, wherein the time is 2 minutes and 20 seconds, the inflatable object 1 is inflated to 2.4bar, the load voltage is 8.62V after the first inflation, and the apparent residual electric quantity is 74.3%; the inflatable object 2 is inflated for the second time, the time is consumed for 2 minutes and 20 seconds, the inflatable object 2 is inflated to 2.4bar, the load voltage is 8.15V after the second inflation is finished, and the apparent residual electric quantity is 55.1%; the inflatable object 3 is inflated for the third time, the time is 2 minutes and 38 seconds, the inflatable object 3 is inflated to 2.4bar, the load voltage is 7.92V after the third inflation is finished, and the apparent residual electric quantity is 45.7%; the inflatable object 4 is inflated for the fourth time, the time is taken for 2 minutes and 40 seconds, the inflatable object 4 is inflated to 2.4bar, the load voltage is 7.63V after the fourth inflation is completed, and the apparent residual electric quantity is 33.9%; and (4) inflating the inflatable object 4 for the fifth time, wherein after the inflatable object is inflated for 1 minute and 50 seconds, the voltage of the electric inflator reaches the protection voltage of 6.8V, the electric inflator stops at the moment, the displayed residual electric quantity is 0%, and the inflatable object 5 is inflated to 2.2bar at the moment.
