Description

Technical Field

[0001] This application relates to the field of inflation equipment technology, and in particular to an inflation pump, an inflation pump control method, an inflation pump control device, and a computer-readable storage medium. Background Technology

[0002] In daily life and production, people often encounter situations where inflatable objects such as vehicle tires, ball equipment, swimming rings, and kayaks are short of air. In such cases, people usually use an air pump to inflate the inflatable objects.

[0003] An air pump, also known as a tire inflator, is a tool for inflating air, powered by a motor. It consists of a motor, transmission assembly, piston rod, check valve, and cylinder. The principle is that the motor drives the transmission assembly, causing the piston rod to reciprocate within the cylinder, thus inflating the air.

[0004] Currently, air pressure sensors are installed in the output air path of air pumps. After the output air path is connected to the object to be inflated, the total amount of gas output by the air pump is determined by detecting the air pressure of the object before inflation and during inflation. However, the readings of the air pressure sensor are affected by both the gas output by the air pump and the gas inside the object to be inflated. The accuracy of the total gas volume obtained solely from this air pressure sensor is not high, resulting in a discrepancy between the final inflation effect and the user's expectations, leading to a poor user experience. Summary of the Invention

[0005] Therefore, it is necessary to provide an air pump, an air pump control method, an air pump control device, and a computer-readable storage medium to accurately detect the total amount of gas output to the object to be inflated during the operation of the air pump, thereby improving the inflation effect.

[0006] In a first aspect, this application provides an air pump. The air pump includes: a control module, an inflation mechanism, and a magnetoelectric detection module; the control module is electrically connected to both the inflation mechanism and the magnetoelectric detection module; the magnetoelectric detection module is mechanically connected to a piston push rod in the inflation mechanism.

[0007] The inflation mechanism is used to operate under the control of the control module and output gas.

[0008] The magnetoelectric detection module is used to generate an induced current based on the reciprocating motion of the piston rod during the operation of the inflation mechanism.

[0009] The control module receives the induced current and determines the total amount of gas output by the inflation mechanism based on the induced current.

[0010] In one embodiment, the magnetoelectric detection module includes a magnetic conductor, an induction coil, and a magnet;

[0011] The magnetic conductor is disposed on the piston push rod and reciprocates along with the piston push rod during the operation of the inflation mechanism.

[0012] The induction coil is disposed on the outer periphery of the magnetic conductor, and the magnet is disposed within the movement range of the magnetic conductor. When the magnetic conductor moves to contact the magnet during its reciprocating motion, the induction coil generates a first induced current.

[0013] In one embodiment, the magnet includes an N-pole magnet and an S-pole magnet;

[0014] The N-pole magnet is positioned at the first sensing position, and the S-pole magnet is positioned at the second sensing position. The first sensing position and the second sensing position are different positions within the movement range of the magnetic conductor. During the reciprocating motion, the magnetic conductor alternately contacts the N-pole magnet and the S-pole magnet, causing the induction coil to generate a second induced current.

[0015] In one embodiment, the control module includes a controller and a current monitoring unit, the current monitoring unit being electrically connected to the magnetoelectric detection module and the controller respectively, and the controller being electrically connected to the inflation mechanism;

[0016] The current monitoring unit is used to monitor the induced current and output a corresponding detection current signal;

[0017] The controller is used to determine the total amount of air output based on the detected current signal.

[0018] In one embodiment, the air pump further includes an energy storage element, and the control module is electrically connected to the energy storage element and the magnetoelectric detection module respectively. The control module is also used to charge the energy storage element according to the induced current.

[0019] In one embodiment, the control module includes a controller and a voltage detection unit, the voltage detection unit being electrically connected to the controller and the energy storage element respectively, and the controller being electrically connected to the inflation mechanism and the magnetoelectric detection module respectively.

[0020] The voltage detection unit is used to detect the voltage of the energy storage element and output the voltage parameters of the energy storage element.

[0021] The controller charges the energy storage element according to the induced current when the voltage parameter is lower than the preset voltage value; and stops charging the energy storage element when the voltage parameter reaches the preset voltage value.

[0022] In one embodiment, the inflation mechanism includes a motor, gears, a piston rod, and an air outlet assembly. The motor is electrically connected to the control module, and the gears are mechanically connected to both the motor and the piston rod.

[0023] The control module is used to control the motor to drive the gear to rotate, thereby driving the piston rod to reciprocate, so that the gas outlet assembly outputs gas.

[0024] Secondly, this application provides a method for controlling an air pump. The method includes:

[0025] Receive inflation control signal and control the operation of inflation mechanism to make inflation mechanism output gas;

[0026] The system receives an induced current and determines the total amount of gas output by the inflation mechanism based on the induced current. The induced current is generated by the magnetoelectric detection module during the operation of the inflation mechanism based on the reciprocating motion of the piston push rod of the inflation mechanism. The magnetoelectric detection module is mechanically connected to the piston push rod in the inflation mechanism.

[0027] In one embodiment, determining the total output gas of the inflation mechanism based on the induced current includes:

[0028] The current accumulation is determined based on the induced current.

[0029] The number of reciprocating motions of the piston rod is determined based on the accumulated current.

[0030] The total amount of gas output by the inflation mechanism is determined based on the number of reciprocating cycles.

[0031] In one embodiment, after determining the total output gas of the inflation mechanism based on the induced current, the method further includes: controlling the inflation mechanism to stop operating when the total output gas reaches the target gas volume corresponding to the charging control signal.

[0032] Thirdly, this application also provides a control device for an air pump. The device includes:

[0033] An inflation control module is used to receive inflation control signals and control the operation of the inflation mechanism so that the inflation mechanism outputs gas.

[0034] An output volume determination module is used to receive induced current and determine the total output volume of the inflation mechanism based on the induced current; the induced current is generated by a magnetoelectric detection module during the operation of the inflation mechanism based on the reciprocating motion of the piston push rod of the inflation mechanism, and the magnetoelectric detection module is mechanically connected to the piston push rod in the inflation mechanism.

[0035] Fourthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, performs the following steps:

[0036] Receive inflation control signal and control the operation of inflation mechanism to make inflation mechanism output gas;

[0037] The system receives an induced current and determines the total amount of gas output by the inflation mechanism based on the induced current. The induced current is generated by the magnetoelectric detection module during the operation of the inflation mechanism based on the reciprocating motion of the piston push rod of the inflation mechanism. The magnetoelectric detection module is mechanically connected to the piston push rod in the inflation mechanism.

[0038] The aforementioned air pump, air pump control method, air pump control device, and computer-readable storage medium include a control module, an air inflation mechanism, and a magnetoelectric detection module. The control module is electrically connected to both the air inflation mechanism and the magnetoelectric detection module. The magnetoelectric detection module is mechanically connected to the piston push rod in the air inflation mechanism. The air inflation mechanism operates under the control of the control module and outputs gas. The magnetoelectric detection module generates an induced current based on the reciprocating motion of the piston push rod during the operation of the air inflation mechanism. The control module receives the induced current and determines the total output gas volume of the air inflation mechanism based on the induced current. Therefore, the determination of the total output gas volume of this air pump is not affected by the gas pressure inside the object to be inflated. The total output gas volume is obtained solely based on the reciprocating motion state of the piston push rod related to the output gas volume during the operation of the air inflation mechanism. Thus, the total output gas volume is more accurate. Consequently, the inflation control based on this total output gas volume is more accurate, making the final inflation effect more in line with the user's expectations. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0051] In one embodiment, such as Figure 1 As shown, an air pump is provided, including a control module 100, an air inflation mechanism 200, and a magnetoelectric detection module 300. The control module 100 is electrically connected to both the air inflation mechanism 200 and the magnetoelectric detection module 300; the magnetoelectric detection module 300 is mechanically connected to the piston push rod in the air inflation mechanism 200 (the mechanical connection is not shown in the figure). The air inflation mechanism 200 operates under the control of the control module 100 and outputs gas. The magnetoelectric detection module 300 generates an induced current based on the reciprocating motion of the piston push rod during the operation of the air inflation mechanism 200. The control module 100 receives the induced current and determines the total amount of gas output by the air inflation mechanism 200 based on the induced current.

[0052] Specifically, the inflation mechanism 200 is also used to connect inflatable objects such as tires, sports equipment, and kayaks. Upon receiving an inflation control signal, the control module 100 can control the inflation mechanism 200 to start operating, outputting gas to the inflatable object to inflate it. The source of the inflation control signal is not limited. For example, the air pump can be equipped with an input module electrically connected to the control module 100, and the inflation control signal can be an activation command issued by the user through the input module. The input module can be a button, a touchscreen, or a signal receiving module communicatively connected to a user terminal for inputting inflation control signals from the user terminal. The air pump can also be equipped with an inflation detection module electrically connected to the control module 100. After the inflation mechanism 200 is connected to the inflatable object, it detects whether the object needs inflation. If inflation is required, it outputs an inflation control signal to the control module 100.

[0053] The structure of the inflation mechanism 200 does not need to be limited. For example, such as... Figure 2 As shown, the inflation mechanism 200 includes a motor, gears, a piston rod, and an air outlet assembly. The motor is electrically connected to the control module 100, and the gears are mechanically connected to both the motor and the piston rod. The control module 100 is used to control the motor to drive the gears to rotate, thereby causing the piston rod to reciprocate, so that the air outlet assembly outputs gas.

[0054] Specifically, the motor drives the gears, which in turn drive the piston rod, which in turn compresses the gas, causing the gas outlet assembly to output gas to inflate the object. It can be understood that, in actual implementation, the inflation mechanism 200 can also... Figure 2 Based on the illustrated embodiment, more or fewer components may be adaptively set, which will not be elaborated in this embodiment.

[0055] The magnetoelectric detection module 300 is a device that can generate induced current through electromagnetic induction. The magnetoelectric detection module 300 is mechanically connected to the piston push rod. During the operation of the motor, the gear drives the piston push rod to reciprocate. The magnetoelectric detection module 300 generates induced current based on the reciprocating motion of the piston push rod, and then the control module 100 determines the total amount of gas output by the inflation mechanism 200 based on the induced current.

[0056] The aforementioned air pump includes a control module 100, an inflation mechanism 200, and a magnetoelectric detection module 300. The control module 100 is electrically connected to both the inflation mechanism 200 and the magnetoelectric detection module 300; the magnetoelectric detection module 300 is mechanically connected to the piston push rod in the inflation mechanism 200. The inflation mechanism 200 operates under the control of the control module 100, outputting gas. The magnetoelectric detection module 300 generates an induced current based on the reciprocating motion of the piston push rod during the operation of the inflation mechanism 200. The control module 100 receives the induced current and determines the total output gas volume of the inflation mechanism 200 based on it. Therefore, the process of obtaining this total output gas volume is unaffected by the gas pressure inside the object to be inflated, but is based solely on the reciprocating motion state of the piston push rod related to the output volume during the operation of the inflation mechanism 200. Thus, the total output gas volume is more accurate. Consequently, inflation control based on this total output gas volume is also more accurate, ensuring that the final inflation effect matches the user's expectations.

[0057] In one embodiment, such as Figure 3 As shown, the magnetoelectric detection module 300 includes a magnetic conductor, an induction coil, and a magnet. The magnetic conductor is disposed on the piston rod and reciprocates along with the piston rod during the operation of the inflation mechanism 200. The induction coil is disposed on the outer periphery of the magnetic conductor, and the magnet is disposed within the movement range of the magnetic conductor. During the reciprocating motion, when the magnetic conductor moves to contact the magnet, the induction coil generates a first induced current.

[0058] Specifically, the magnetic conductor can be fixed to the side of the piston rod near the magnet to reciprocate with the piston rod. An induction coil is disposed around the outer periphery of the magnetic conductor. The size of the induction coil is determined based on the range of motion of the magnetic conductor, ensuring that the magnetic conductor remains within the coil throughout its movement. The magnet is positioned within the range of motion of the magnetic conductor. During one reciprocating motion, the magnetic conductor will contact the magnet at least once. During this contact, the magnetic conductor is magnetized, changing the magnetic flux of the induction coil and generating a first induced current.

[0059] The method of fixing the magnet and the induction coil can be set according to the actual situation. For example, inside the housing of the air pump, there is a fixing mechanism for the magnet and the induction coil to fix them. After fixing, the magnet and the induction coil will not affect the movement trajectory of the magnetic conductor. The polarity of the magnet, the size of the magnet, the size of the induction coil, the number of turns of the induction coil, and other parameters can be set according to the actual situation.

[0060] In one embodiment, such as Figure 4As shown, the magnet includes an N-pole magnet and an S-pole magnet; the N-pole magnet is set at the first induction position, and the S-pole magnet is set at the second induction position. The first induction position and the second induction position are different positions within the movement range of the magnetic conductor; during the reciprocating motion, the magnetic conductor alternately contacts the N-pole magnet and the S-pole magnet, causing the induction coil to generate a second induced current.

[0061] Understandable. Figure 4 The positions of the N-pole and S-pole magnets shown are merely illustrative. During one reciprocating motion of the magnetic conductor, it will come into contact with the N-pole and S-pole magnets respectively. This alternating contact with the N-pole and S-pole magnets causes the magnetism of the magnetic conductor to continuously change, and the induction coil, whose magnetic flux changes, generates a second induced current.

[0062] Based on the above embodiments, the control module 100 can employ various possible methods when determining the total output gas of the inflation mechanism 200 based on the induced current. In one embodiment, the control module 100 can first determine the cumulative current of the induced current, then determine the number of reciprocating motions of the piston push rod based on the cumulative current, and finally determine the total output gas based on the number of reciprocating motions. It is understood that after the structure and parameters of the inflation mechanism 200 are determined, the induced current generated by the induction coil during each reciprocating motion of the piston push rod is constant, and the output gas volume of the gas outlet assembly is also constant during each reciprocating motion of the piston push rod. Therefore, in this embodiment, the total output gas volume of the gas outlet assembly can be determined based on the actual movement of the piston push rod, and the reliability of the total output gas volume calculated in this way is higher.

[0063] In another embodiment, the number of reciprocating motions of the piston rod can also be determined based on the state of the induced current. For example, when the magnetic conductor contacts the magnet, the induction coil generates a first induced current; when the magnetic conductor and the magnet are not in contact, the induction coil stops generating the induced current. Therefore, the number of reciprocating motions of the piston rod can be determined based on the number of times the first induced current is detected from the induction coil. When the magnet includes both N-pole and S-pole magnets, the controller can also determine the number of reciprocating motions of the piston rod based on the number of times a second induced current is detected from the induction coil. Furthermore, after the magnetic conductor alternately contacts the N-pole and S-pole magnets, the current direction changes; therefore, the reciprocating state of the piston rod can also be determined based on the change in the second induced current.

[0064] It is understandable that the magnitudes of the first and second induced currents are related to specific parameters such as the number of turns of the coil and the size of the magnet. Generally, the magnetoelectric detection module 300 uses two magnets (e.g., Figure 4 The structure of the embodiment shown is similar to that of setting a magnet (such as...). Figure 3Compared to the structure of the illustrated embodiment, both methods can meet the requirements in terms of detection accuracy. However, when two magnets are used, the second induced current obtained with each reciprocating motion of the piston rod will be greater than the first induced current. If it is necessary to recycle the induced current, two magnets, one with an N pole and one with a S pole, can be set in the magnetoelectric detection module 300 as needed. The specific design needs to be determined based on the actual situation, such as the required magnitude of the induced current, cost, and volume.

[0065] It should be noted that in traditional technologies, when detecting the total air volume using a pressure sensor, the high price of the pressure sensor leads to a high cost for the air pump. In this embodiment, the total cost of the magnetoelectric detection module 300 is much lower than that of the pressure sensor, which can significantly reduce the cost of the air pump, especially in mass production, where the total cost savings will be very substantial.

[0066] In one embodiment, such as Figure 5 As shown, the control module 100 includes a controller 110 and a current monitoring unit 120. The current monitoring unit 120 is electrically connected to the magnetoelectric detection module 300 and the controller 110 respectively. The controller 110 is also electrically connected to the inflation mechanism 200. The current monitoring unit 120 is used to monitor the induced current and output the corresponding detection current signal. The controller 110 is used to determine the total amount of air output based on the detection current signal.

[0067] Specifically, the controller 110 controls the operation of the inflation mechanism 200 to output gas. During the operation of the inflation mechanism 200, the current monitoring unit 120 monitors the induced current (first induced current or second induced current) output by the induction coil in real time and outputs a detection current signal to the controller 110 in real time. Each time the controller 110 receives a detection current signal, it synchronously records the receiving time and duration. Furthermore, the controller 110 calculates the accumulation of the induced current over time based on the detection current signal, performs integral calculation, and the final integral result is used as the current accumulation.

[0068] The current monitoring unit 120 can be implemented using any structure that can realize current detection, and the specific connection method between the current monitoring unit 120 and the magnetoelectric detection module 300 can be set according to the specific structure of the current monitoring unit 120.

[0069] In practical implementation, the control module 100 can be adaptively adjusted according to the specific structure of the magnetoelectric detection module 300. For example, the magnetoelectric detection module 300 is as follows: Figure 4As shown in the diagram, it can be understood that when the magnetic conductor comes into contact with the N-pole magnet and the S-pole magnet, the direction of the second induced current changes. Correspondingly, the control module 100 may also include a phase current conversion module, which is connected between the induction coil and the current monitoring unit 120. This phase current conversion module is used to adjust the current direction so that the current input to the current monitoring unit 120 and the controller 110 always has the same direction. The phase current conversion module can be a circuit capable of adjusting the current direction, such as a rectifier circuit.

[0070] In one embodiment, such as Figure 6 As shown, the air pump also includes an energy storage element 400. The control module 100 is electrically connected to the energy storage element 400 and the magnetoelectric detection module 300 respectively. The control module 100 is also used to charge the energy storage element 400 according to the induced current.

[0071] The energy storage element 400 can be a battery, capacitor, or other element capable of storing electrical energy. The electrical energy stored in the energy storage element 400 can be used to power the control module 100, or it can power both the control module 100 and the inflation mechanism 200 simultaneously, or it can power other devices. The specific settings can be configured according to the parameters of the energy storage element 400 and the control requirements during actual implementation.

[0072] In this embodiment, during the operation of the inflation mechanism 200, the magnetoelectric detection module 300 generates an induced current. On the one hand, the induced current is used to detect the total amount of gas output by the inflation mechanism 200; on the other hand, the induced current is also used to charge the energy storage element 400, thereby utilizing energy conversion to realize energy recovery and reuse. This not only extends the running time of the entire inflation pump but also improves the energy utilization rate of the inflation pump.

[0073] In one embodiment, such as Figure 7 As shown, the control module 100 includes a controller 110 and a voltage detection unit 130. The voltage detection unit 130 is electrically connected to the controller 110 and the energy storage element 400. The controller 110 is also electrically connected to the inflation mechanism 200. The voltage detection unit 130 is used to detect the voltage of the energy storage element 400 and output the voltage parameters of the energy storage element 400. When the voltage parameters are lower than a preset voltage value, the controller 110 charges the energy storage element 400 according to the induced current; when the voltage parameters reach the preset voltage value, it stops charging the energy storage element 400.

[0074] The preset voltage value needs to be set in conjunction with the specific parameters of the energy storage element 400. Taking a certain type of battery as an example, this type of battery can be charged up to 4.2V, but overcharging can easily damage the battery. It is generally believed that charging to 3.7V is better for the battery's lifespan. Based on this, the preset voltage value can be set to 3.7V. During the operation of the air pump, when the detected battery voltage parameter reaches 3.7V, the battery is considered fully charged, and charging is stopped to protect the battery. If the battery voltage parameter does not reach 3.7V, the battery is considered not fully charged, and charging can continue to increase its stored energy and achieve energy recovery.

[0075] In practical implementation, the implementation method of the voltage detection unit 130 is not limited, as long as it can detect the voltage of the energy storage element 400. It is understood that the controller 110 may also include circuits such as a charging controller and a charging module to charge the battery. Those skilled in the art can refer to commonly used technologies in the field to specifically configure the controller 110, as long as the corresponding functions mentioned above are implemented.

[0076] Furthermore, when the battery powers the inflation mechanism 200, the inflation pump, upon receiving the inflation control signal, can determine the current battery level based on the detection result of the voltage detection unit 130 before starting inflation and display the current battery level, allowing the user to determine whether the current battery level is sufficient to complete the inflation activity. The controller 110 can also estimate the total output air volume of the inflation mechanism 200 based on the current battery level, so that the user understands whether the current output air volume of the inflation pump can meet the demand, facilitating the user to select in advance according to actual needs.

[0077] The following is combined Figure 4 and Figure 8 The working process of the air pump is explained below:

[0078] First, the controller 110 receives an inflation control signal, and the inflation pump starts working. Specifically, the controller 110 controls the motor to operate, the motor drives the gears to operate, the gears drive the piston rod to inflate, and the gas is delivered to the object to be inflated through the air supply pipe in the air outlet assembly. During this process, the piston rod drives the magnetic conductor to move. During the movement of the magnetic conductor, it alternately contacts the N pole and S pole magnets, causing the magnetic conductor to generate magnetism. Its magnetism is constantly changing, and the induction coil, whose magnetic flux is changing, generates an induced current.

[0079] During each reciprocating cycle of the piston push rod, the induced current generated by the induction coil is constant. Therefore, the controller 110 can calculate the number of reciprocating cycles of the piston push rod (i.e., the number of inflation cycles) based on the accumulated amount of detected induced current. The amount of gas output through the air outlet assembly is constant during each reciprocating cycle of the piston push rod. Therefore, by calculating the number of inflation cycles, the total amount of air output by the air pump can be determined, i.e., the amount of air pumped to the object to be inflated.

[0080] During the operation of the motor, the controller 110 continuously monitors the current total air output. When the total air output reaches the set value (which may be the target air volume determined by the charging control signal or a pre-stored fixed value), the controller controls the motor to stop operating, thereby stopping the air pump and completing the entire inflation process.

[0081] During the operation of the air pump, the induced current charges the battery through the charging module circuit of the controller 110. At the same time, the controller 110 receives the battery voltage parameters detected by the voltage detection unit 130 in real time. When the voltage is lower than 3.7V, the battery continues to be charged; when the voltage reaches 3.7V, the battery charging stops, thus realizing the function of energy recovery.

[0082] The aforementioned air pump fully utilizes the principle of energy conversion. Without altering the original structure, it adds a magnetic conductor, a magnet, and an induction coil to convert magnetic energy into electrical energy. The total output air volume during operation is detected by measuring the accumulated induced current. This air pump uses a magnetoelectric detection module 300, composed of a magnetic conductor, a magnet, and an induction coil, to replace the pressure sensor, reducing cost and increasing accuracy. Simultaneously, the induced current recharges the battery through energy recovery, achieving energy recycling.

[0083] In one embodiment, a control method for an air pump is also provided, which can be applied to, for example... Figure 1 In the application environment shown, the control module 100 receives inflation control signals to control the operation of the inflation mechanism 200 so that the inflation mechanism 200 outputs gas; it receives induced current and determines the total amount of gas output by the inflation mechanism 200 based on the induced current; the induced current is generated by the magnetoelectric detection module 300 during the operation of the inflation mechanism 200 based on the reciprocating motion of the piston push rod of the inflation mechanism 200, and the magnetoelectric detection module 300 is mechanically connected to the piston push rod in the inflation mechanism 200.

[0084] In one embodiment, such as Figure 9 As shown, a control method for an air pump is provided, which is applied to... Figure 1 The following steps are used as an example to illustrate the control module 100, including steps 500-600.

[0085] Step 500: Receive inflation control signal and control the inflation mechanism to operate so that the inflation mechanism outputs gas.

[0086] The inflation control signal can be implemented as described in the above embodiments or in other ways. The structure of the inflation mechanism can also be set as described in the above embodiments, and will not be repeated here. After receiving the inflation control signal, the control module controls the motor to drive the gear to rotate, which drives the piston push rod to reciprocate, so that the air outlet component outputs gas. The air outlet component is connected to the object to be inflated, and the gas output by the air outlet component is used to inflate the object.

[0087] Step 600: Receive the induced current and determine the total amount of gas output by the inflation mechanism based on the induced current.

[0088] The induced current is generated by the reciprocating motion of the piston rod of the inflation mechanism during the operation of the magnetoelectric detection module. The magnetoelectric detection module is mechanically connected to the piston rod in the inflation mechanism.

[0089] The structure of the magnetoelectric detection module can also be set with reference to the above embodiment. During the operation of the inflation mechanism, the piston rod reciprocates, the induction coil of the magnetoelectric detection module outputs an induced current, and then the control module determines the total amount of gas output by the inflation mechanism based on the induced current.

[0090] The aforementioned air pump control method, in determining the total air output, is unaffected by the gas pressure inside the object to be inflated. It is based solely on the reciprocating motion of the piston rod related to the air output during the operation of the inflation mechanism. Therefore, this total air output is more accurate. Consequently, inflation control based on this total air output is also more accurate, ensuring the final inflation effect matches the user's expectations and improving the user experience of the air pump.

[0091] In one embodiment, step 600, determining the total output gas of the inflation mechanism based on the induced current, includes:

[0092] The current accumulation is determined based on the induced current.

[0093] The number of reciprocating motions of the piston rod is determined based on the accumulated current.

[0094] The total amount of gas output by the inflation mechanism is determined based on the number of reciprocating cycles.

[0095] In this embodiment, the control module first determines the cumulative amount of the induced current, then determines the number of reciprocating motions of the piston push rod based on the cumulative current, and finally determines the total amount of gas output based on the number of reciprocating motions. It can be understood that once the structure and parameters of the inflation mechanism are determined, the amount of induced current generated by each reciprocating motion of the piston push rod is constant. Simultaneously, the amount of gas output by the gas outlet assembly is also constant with each reciprocating motion of the piston push rod. Therefore, in this embodiment, the total amount of gas output by the gas outlet assembly can be determined based on the actual movement of the piston push rod, and the reliability of the total gas output calculated in this way is higher.

[0096] In one embodiment, such as Figure 10 As shown, step 600 is followed by step 700: when the total amount of air output reaches the target amount of air corresponding to the charging control signal, the charging mechanism is controlled to stop operating.

[0097] It is understandable that when a user sends a charging control signal, the charging control signal may also include a target gas volume, that is, the total amount of gas to be output to the inflation device. When the control module detects that the current total output of the inflation mechanism has reached the target gas volume, it determines that inflation is complete, at which point it controls the inflation mechanism to stop running, and in turn controls the inflation pump to stop.

[0098] In this embodiment, the control module can detect in real time whether the current total air output has reached the target air volume, and shut down the inflation mechanism in time when the total air output reaches the target air volume, so that the user does not need to stay by the inflation pump at all times, thus improving the user's convenience.

[0099] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
