Description

Technical Field

[0001] This invention relates to the field of air pump control technology, and in particular to an air pump and its control method. Background Technology

[0002] Air pumps, as devices that convert electrical energy into gas pressure energy, are widely used in automotive repair, outdoor sports, medical equipment, and household appliances. In practical applications, there are two typical usage scenarios for air pumps: First, when the standard air pressure of the object being inflated is low, the air pump can function as an independent inflation device, simply connecting it directly to the object to inflate it. Second, when the standard air pressure of the object being inflated is high, a standalone air pump is insufficient for direct inflation. Therefore, in this scenario, the air pump is typically connected to an air storage module, which then inflates the object.

[0003] Existing air pumps typically have only a single control system for use in a single scenario, or they may have two control systems that users must manually switch between depending on the scenario. Because different control systems correspond to different scenarios, existing air pumps cannot automatically inflate objects in complex situations, resulting in poor versatility and low ease of use.

[0004] Therefore, it is evident that the existing technology lacks a control method that can automatically switch between different working modes based on the current usage status of the air pump, so that the air pump can provide adaptive control logic in different usage scenarios. Summary of the Invention

[0005] This invention provides an air pump and its control method to overcome the shortcomings of the prior art and realize flexible switching of the working state of the air pump according to the usage scenario.

[0006] According to one aspect of the present invention, a control method for an air pump is provided, the control method comprising: During the operation of the air pump, the working mode, gas pressure information and interface detection information of the air pump are acquired in real time; Based on at least one of the following: the operating mode of the air pump at the current moment, gas pressure information, or interface detection information, determine the operating mode of the air pump at the next moment, and control the air pump to switch to the operating mode determined above at the next moment.

[0007] Optionally, the interface detection information includes a feedback signal characterizing whether the air pump and the inflated object are properly connected, and an identification signal characterizing the type of the inflated object.

[0008] Optionally, the air pump's operating modes include at least an independent operating mode and an integrated operating mode. The independent operating mode includes at least an automatic mode. In automatic mode, the air pump replenishes the object to be inflated to a standard pressure. In integrated operating mode, the air pump continuously or intermittently replenishes the object to be inflated to a target pressure based on the object's current pressure. Based on at least one of the air pump's current operating mode, gas pressure information, or interface detection information, the air pump's operating mode for the next moment is determined, and the operating mode of the air pump is switched to the determined operating mode at the next moment, including: When a feedback signal and / or identification signal is received, the control air pump switches to automatic mode or integrated working mode at the next moment.

[0009] Optionally, the air pump's operating modes include an independent operating mode and an integrated operating mode. The independent operating mode includes at least a creation mode. In creation mode, the air pump is controlled to stop when a user-inputted stop command is received. In integrated operating mode, the air pump continuously or intermittently replenishes air to the target pressure of the object being inflated, based on the object's current pressure. Based on at least one of the air pump's current operating mode, gas pressure information, or interface detection information, the air pump's operating mode for the next moment is determined, and the air pump's operating mode is switched to the determined operating mode at the next moment, including: When the air pump is in creative mode at the current moment, determine whether the pressure information meets the preset conditions; If so, the operating mode of the air pump will be switched to the integrated operating mode.

[0010] Optionally, the air pump may also have an independent operating mode, which may include at least an automatic mode. Control methods also include: When the air pump is running in automatic mode, it acquires the temperature information of the current working environment; Determine the standard pressure of the air pump based on temperature information and a pre-stored temperature-tire pressure mapping table; Once the pressure value expressed by the pressure information reaches the standard pressure, the air pump is controlled to stop.

[0011] Optionally, the standalone working mode also includes a custom mode; After determining the standard pressure of the air pump, the following is also included: Real-time acquisition of user input for mode selection; mode selection commands include commands to switch to a custom mode; Upon receiving a command to switch to custom mode, the air pump's operating mode is switched to custom mode, and pressure adjustment commands are received in real time. When a pressure adjustment command is received, the standard pressure is finely adjusted according to the command with a preset step size.

[0012] Optionally, the control methods also include: After the air pump stops, control the cooling fan to continue working and record the air pump's downtime. Determine whether the downtime meets the preset downtime; If so, the cooling fan will be shut down and a timeout warning will be issued.

[0013] Optionally, the control methods also include: When the downtime does not meet the preset downtime, the operating temperature information of the air pump is obtained in real time. Determine whether the operating temperature information of the air pump meets the preset temperature conditions; If so, then control the cooling fan to stop.

[0014] Optionally, before the air pump stops, the control method further includes interface detection information including an identification signal characterizing the type of object being inflated, and determining the preset shutdown time and / or speed of the cooling fan based on the identification signal.

[0015] In a second aspect, the present invention also provides an air pump, comprising: a pump body, an air outlet, a connecting air pipe, a pressure sensor, an interface detection element, and a controller; the air outlet is connected to the pump body, and the pressure sensor is disposed inside the air outlet; the connecting air pipe is connected to the air outlet, and the interface detection element is disposed at the end of the connecting air pipe away from the air outlet; The controller is used to execute the control method for the air pump described in any of the above-mentioned embodiments.

[0016] Optionally, the air pump also includes a housing, a cooling fan, a first temperature sensor, and a second temperature sensor. The first temperature sensor is located on the housing, and the second temperature sensor is located on the mechanism of the air pump.

[0017] This invention acquires the air pump's operating mode, gas pressure information, and interface detection information in real time during the operation of the air pump. Based on at least one of the air pump's current operating mode, gas pressure information, and interface detection information, it determines the air pump's operating mode for the next moment and controls the air pump to switch to the determined operating mode at the next moment. This allows the air pump to automatically switch operating modes according to its own state and the pressure information from the pressure sensor or the connection status of the air hose, thus providing adaptable control logic for the air pump in different usage scenarios. This improves the air pump's versatility and convenience, simplifies user operation, and enhances the user experience.

Other features of the invention will become readily apparent from the following description. Attached Figure Description

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] Example 1 Figure 1This is a structural block diagram of an air pump provided in Embodiment 1 of the present invention, with reference to... Figure 1 As shown, the air pump includes a pump body, an air outlet, a connecting air pipe, a pressure sensor, an interface detection element, and a controller. The air outlet is connected to the pump body, the pressure sensor is located inside the air outlet, the connecting air pipe is connected to the air outlet, and the interface detection element is located at the end of the connecting air pipe away from the air outlet. The controller is used to execute the control method of the air pump provided in any embodiment of the present invention. Optionally, the controller can be set as an MCU (Microcontroller Unit) or a CPU (Central Processing Unit), etc.

[0024] The pump body is the core component used to generate compressed air; the air outlet is connected to the pump body and is used to output compressed air to the outside.

[0025] A pressure sensor is installed inside the air outlet to detect the air pressure value at the outlet in real time, enabling precise monitoring of the air pressure of the inflated object during inflation. The pressure information from the pressure sensor includes the pressure value acquired by the sensor. In an optional embodiment, the pressure sensor includes a ceramic piezoresistive pressure sensor. Ceramic piezoresistive pressure sensors offer advantages such as corrosion resistance, impact resistance, and no hysteresis, making them suitable for frequent pressure pulses from the air pump and harsh working environments. Furthermore, they improve measurement accuracy.

[0026] One end of the connecting tube is connected to the air outlet, and the end away from the air outlet is used to connect to the object being inflated, so that the air outlet outputs compressed air to the object being inflated through the connecting tube. An interface detection element is located at the end of the connecting tube away from the air outlet, that is, at the end connected to the object being inflated, enabling the interface detection element to detect whether the connected object is the first object to be inflated. Specifically, when the connecting tube is connected to the first object being inflated and the connection is secure, the interface detection element is triggered and receives a feedback signal. Conversely, when the connecting tube is not connected to the first object being inflated, or when the connection is not secure (e.g., the connection is not tight), the interface detection element is not triggered and detects an invalid signal. The first object being inflated can be understood as an object that can be identified by the interface detection element.

[0027] In an optional embodiment, the interface detection element may include a Hall sensor. In this case, the first inflatable object is an inflatable object with a small magnet disposed near the air nozzle. When the first inflatable object is connected to the connecting air tube, the Hall sensor is triggered, thereby causing the interface detection element to receive a feedback signal. Conversely, when the first inflatable object is not connected to the connecting air tube, or when the inflatable object connected to the connecting air tube is not the first inflatable object, the Hall sensor is not triggered, causing the interface detection element to receive an invalid signal.

[0028] In another optional embodiment, the interface detection element may include a mechanical micro switch. In this case, the nozzle of the first inflatable object is designed with a corresponding trigger protrusion, such as a trigger ring or a stop. When the first inflatable object is connected to the connecting air tube, the mechanical micro switch is triggered, causing the interface detection element to receive a feedback signal. Conversely, when the first inflatable object is not connected to the connecting air tube, or when the inflatable object connected to the connecting air tube is not the first inflatable object, the mechanical micro switch is not triggered, causing the interface detection element to receive an invalid signal.

[0029] In another optional embodiment, the interface detection element may include an infrared beam sensor, in which case the nozzle of the first inflatable object is designed with a corresponding baffle. When the first inflatable object is connected to the connecting air tube, the baffle of the first inflatable object is precisely inserted into the U-shaped groove of the infrared beam sensor, and the baffle completely blocks the infrared light, so that the interface detection element receives a feedback signal; conversely, when the first inflatable object is not connected to the connecting air tube, or when the inflatable object connected to the connecting air tube is not the first inflatable object, the interface detection element receives an invalid signal.

[0030] Understandably, the interface detection element in the above embodiments can only identify whether the first inflatable object is connected to the air pump, but cannot identify what specific product the first inflatable object is. In another optional embodiment, the interface detection element further includes an electronically controlled detection circuit, where different types of first inflatable objects have corresponding circuit resistors; the circuit resistance collected by the interface detection element differs when the air pump connects to different inflatable objects. At this time, the controller compares the resistance value represented by the collected identification signal with an internally preset database, and can distinguish what specific product the first inflatable object is based on the resistance value. For example, the first inflatable object can be a car tire, a balloon, or an air tank, etc.

[0031] In an optional embodiment, the air pump is further provided with a human-machine interface module. The human-machine interface module includes physical buttons on the air pump, through which the user inputs control commands by pressing the physical buttons on the air pump, and / or, the human-machine interface module includes a touch screen on the air pump, through which the user inputs control commands by touching the touch screen on the air pump.

[0032] Optionally, the air pump also includes a housing, a cooling fan, a first temperature sensor, and a second temperature sensor located outside the pump body. The first temperature sensor is disposed on the housing, and the second temperature sensor is disposed on the core of the air pump.

[0033] The outer casing houses and protects the internal components of the air pump. A first temperature sensor is mounted on the casing to acquire the ambient temperature. It should be noted that the first temperature sensor can be located on either the inner or outer surface of the casing, as long as it can effectively sense the temperature of the environment in which the air pump operates.

[0034] The air pump's core mechanism refers to the integrated working unit comprising the motor, transmission mechanism, and pump body. The cooling fan, located inside the casing and adjacent to the core mechanism, is a component used for forced air cooling. A second temperature sensor monitors the core mechanism's operating temperature in real time. During operation, the cooling fan continuously dissipates heat to prevent overheating and damage. After the air pump stops, the controller can, based on the core mechanism temperature detected by the second temperature sensor or a preset cooling duration, control the cooling fan to continue running for a period to expel residual heat from the core mechanism, achieving delayed heat dissipation protection.

[0035] Since the air pump provided in this embodiment of the invention includes the controller, pump body, air outlet and pressure sensor described above, and the controller can execute the control method of the air pump provided in this embodiment of the invention, it can have the corresponding structure and features to execute the control method of the air pump provided in this embodiment of the invention, and can achieve the beneficial effects of the control method of the air pump provided in this embodiment of the invention. The similarities can be referred to in the following description.

[0036] Example 2 The air pump control method provided in this embodiment of the invention can be used to automatically switch the air pump to an integrated working mode. Figure 2 This is a flowchart of a control method for an air pump provided in Embodiment 2 of the present invention, referred to... Figure 2 As shown, the control method includes: S110. During the operation of the air pump, the working mode, gas pressure information and interface detection information of the air pump are acquired in real time.

[0037] The air pump includes a pump body, an air outlet, a connecting air pipe, a pressure sensor, and an interface detection element. The air outlet is connected to the pump body, and the pressure sensor is located inside the air outlet to obtain gas pressure information. The connecting air pipe is connected to the air outlet, and the interface detection element is located at the end of the connecting air pipe away from the air outlet.

[0038] The air pump is also equipped with a human-machine interface module, which is used to receive control commands input by the user. The control commands may include, but are not limited to, at least one of the following: mode selection command, start / stop command, and pressure adjustment command. The pressure adjustment command is used to set the target air pressure value, the mode selection command is used to select the inflation mode, and the start / stop command is used to directly control the start and stop of the air pump.

[0039] The air pump operates in two modes: independent and integrated. Independent modes include at least automatic, custom, and creative modes. Automatic mode allows the air pump to determine a standard pressure based on user-inputted mode selection commands or by detecting a first object being inflated via an interface detection element. The pump automatically stops when the pressure at the outlet reaches the standard pressure. In one optional embodiment, automatic mode may include at least one of a car scenario, a motorcycle scenario, or a ball scenario, where the object being inflated can be at least one of a car tire, a motorcycle tire, or a ball. Custom mode sets the standard pressure of the air pump based on user-inputted pressure settings, controlling the pump to stop when the pressure value expressed by the pressure information reaches the standard pressure. Creative mode controls the air pump to stop based on user-inputted stop commands.

[0040] In integrated operating mode, the air pump works in conjunction with the object being inflated, continuously or intermittently replenishing air to the target pressure based on the pressure of the object. Specifically, when the pressure of the object is lower than the set target pressure value, the air pump continuously replenishes air; when the pressure reaches the set target pressure value, the air pump stops; and when the pressure drops to the set replenishment pressure value, the air pump restarts to replenish air. Here, the object being inflated refers to an independent functional unit connected to the air pump for storing compressed air; exemplarily, the object being inflated includes an air storage tank. In this embodiment, the set target pressure value and the set replenishment pressure value can be determined according to actual needs. For example, when the object being inflated is an air storage tank, the set standard pressure value can be 8 bar, and the set replenishment pressure value can be 5 bar.

[0041] Optionally, after obtaining the working mode of the air pump, the system also includes displaying the current working mode of the air pump, so that users can confirm the working status of the air pump and avoid inflation errors caused by mode misjudgment.

[0042] The gas pressure information from the pressure sensor includes the pressure value acquired by the pressure sensor. The interface detection information from the interface detection element includes a feedback signal and an identification signal; the feedback signal is the signal acquired by the interface detection element when the air pump and the object being inflated are connected in place, and the identification signal is the signal acquired by the interface detection element based on the type of the object being inflated after the air pump and the object are connected in place. For example, when the first object being inflated is a car tire, the interface detection element detects a first identification signal. At this time, the controller can determine that the car tire and the air pump are connected in place based on the first identification signal. If the first object being inflated is a balloon, the interface detection element detects a second identification signal. At this time, the controller can determine that the balloon and the air pump are connected in place based on the second identification signal.

[0043] S120. Determine the operating mode of the air pump at the next moment based on at least one of the operating mode of the air pump at the current moment, gas pressure information, or interface detection information, and control the air pump to switch to the operating mode determined above at the next moment.

[0044] In an optional embodiment, S120 includes: when a feedback signal and / or identification signal is received, controlling the air pump to switch to automatic mode or integrated working mode at the next moment.

[0045] Specifically, the operating mode of the air pump at the next moment is related to the interface detection information of the interface detection element. When the air pump is connected to the first object to be inflated, the signal obtained by the interface detection element is a feedback signal. At this time, the interface detection element further detects the category of the first object to be inflated and controls the air pump to switch its operating mode to the operating mode corresponding to the first object to be inflated based on the obtained identification signal. For example, when the first object to be inflated is detected to be a car tire, the operating mode of the air pump is controlled to switch to the car scenario in automatic mode; when the first object to be inflated is detected to be an air tank, the operating mode of the air pump is controlled to switch to the integrated operating mode.

[0046] In addition, the working mode of the air pump can be switched to the integrated working mode directly based on whether there is a feedback signal. In this solution, the structure of the interface detection element is relatively simple and it is suitable for use scenarios with low complexity.

[0047] It should be noted that the interface detection information obtained by the interface detection element is the highest-level condition for controlling the air pump to switch its working mode. In other words, when the interface detection element obtains the interface detection information, regardless of the current working mode of the air pump, it controls the air pump to switch to the corresponding working mode in the next moment.

[0048] In another optional embodiment, S120 includes: when the working mode of the air pump at the current moment is the creation mode, determining whether the gas pressure information meets the preset conditions; if the gas pressure information meets the preset conditions, controlling the working mode of the air pump to switch to the integrated working mode.

[0049] The preset conditions include a pressure value represented by the gas pressure information being greater than or equal to a preset pressure threshold. The preset pressure threshold is a pre-stored set pressure value of the air pump or a set pressure value input by the user through the human-machine interaction module. In an optional embodiment, the preset pressure value is 3 bar, that is, when the pressure sensor detects a pressure value greater than 3 bar, the air pump's operating mode is switched to the integrated operating mode.

[0050] Specifically, during the operation of the air pump, the working mode of the air pump and the gas pressure information from the pressure sensor are acquired in real time. If the working mode of the air pump is the creation mode and the pressure information meets the preset conditions, the conditions for entering the integrated working mode are met. At this time, the working mode of the air pump is switched to the integrated working mode. In the integrated working mode, the air pump continuously or intermittently replenishes the air to the target pressure according to the current pressure of the object being inflated. Conversely, if the working mode of the air pump is the creation mode and the gas pressure information does not meet the preset conditions, or if the working mode of the air pump is the automatic mode or the custom mode, the conditions for entering the integrated working mode are not met. At this time, the air pump is controlled to maintain the original working mode.

[0051] In this embodiment, the air pump includes a pump body, an air outlet, a connecting air pipe, a pressure sensor, and an interface detection element. The pressure sensor is located inside the air outlet, the connecting air pipe is connected to the air outlet, and the interface detection element is located at the end of the connecting air pipe away from the air outlet. During the operation of the air pump, the working mode of the air pump, the gas pressure information of the pressure sensor, and the interface detection information of the interface detection element are acquired in real time. Based on at least one of the working mode, gas pressure information, or interface detection information of the air pump at the current moment, the working mode of the air pump at the next moment is determined, and the working mode of the air pump is switched to the determined working mode at the next moment. This allows the air pump to automatically switch its working mode according to its own state, thereby providing adaptive control logic for the air pump in different usage scenarios, which helps to simplify user operation and improve the inflation efficiency of the air pump.

[0052] Example 3 Figure 3 This is a flowchart of a control method for an air pump provided in Embodiment 3 of the present invention. This embodiment further adds a step of adaptively adjusting the standard pressure based on ambient temperature in automatic mode, based on the above embodiments. (Refer to...) Figure 3 As shown, the method specifically includes: S210. During the operation of the air pump, the working mode and gas pressure information of the air pump are obtained in real time.

[0053] The air pump has two operating modes: an independent operating mode and an integrated operating mode. The independent operating mode includes at least an automatic mode and a custom mode.

[0054] S220. When the air pump is running in automatic mode, acquire the temperature information of the current working environment.

[0055] In this embodiment, the air pump also includes a housing and a first temperature sensor disposed outside the pump body, the first temperature sensor being disposed on the housing. Optionally, the temperature sensor can also be an infrared sensor or other temperature sensor located outside the air pump, capable of acquiring real-time temperature information of the current working environment.

[0056] When the air pump operates in automatic mode, the controller reads the ambient temperature information detected by the first temperature sensor in real time and adaptively adjusts the inflation strategy based on this information. For example, in low-temperature environments, the elasticity of rubber-based inflatable products decreases, and inflation at the standard pressure set at room temperature may result in underinflation; while in high-temperature environments, gas expands easily, and overinflation may pose a safety hazard. By incorporating the ambient temperature information obtained from the first temperature sensor, the controller can perform temperature compensation correction on the standard pressure, thereby ensuring accurate and safe inflation control under different ambient temperatures.

[0057] S230. Determine the standard pressure of the air pump based on the temperature information and the pre-stored temperature-tire pressure mapping table.

[0058] The controller of the air pump stores a pre-calibrated temperature-tire pressure mapping table inside or outside the system. The temperature-tire pressure mapping table records the standard pressure values ​​corresponding to different ambient temperatures. This mapping relationship can be obtained through experimental calibration based on the physical characteristics of the target object being inflated (such as car tires, motorcycle tires, balls, etc.).

[0059] In one specific implementation, for the scenario of automobile tire inflation, a temperature-tire pressure mapping table as shown in Table 1 can be set up.

[0060] The controller uses the current ambient temperature information as a query index to determine the temperature range to which the ambient temperature belongs, and matches and reads the target tire pressure value corresponding to the temperature range from the temperature-tire pressure mapping table to determine the standard pressure of the air pump under the current working conditions.

[0061] Table 1. Temperature-Tire Pressure Mapping Relationship in Automotive Scenarios Specifically, during the operation of the air pump, the working mode of the air pump and the pressure information of the pressure sensor are acquired in real time. When the air pump is running in automatic mode, the temperature information of the first temperature sensor is also acquired. Based on the temperature information and the pre-stored temperature-tire pressure mapping table, the standard pressure of the air pump is determined. After the pressure value expressed by the pressure information reaches the standard pressure, the air pump is controlled to stop. This allows the air pump to adaptively adjust the standard pressure in automatic mode according to changes in ambient temperature, avoiding the impact of thermal expansion and contraction caused by temperature changes on inflation accuracy.

[0062] S240: Real-time acquisition of user input mode selection commands.

[0063] The mode selection command refers to the control command input by the user through physical buttons or a touch screen to select the inflation mode. The mode selection command may include, but is not limited to, commands to switch to custom mode, commands to switch to creative mode, or commands to switch to automatic mode.

[0064] S250: When receiving an instruction to switch to custom mode, control the air pump to switch its operating mode to custom mode and obtain pressure adjustment instructions in real time.

[0065] The custom mode refers to a working mode where the standard pressure of the air pump is set according to the user-input pressure setting, and the air pump is controlled to stop when the pressure value expressed in the pressure information reaches the standard pressure. Pressure adjustment commands refer to control commands input by the user through the human-machine interface module to adjust the standard pressure. Pressure adjustment commands may include, but are not limited to, commands to increase pressure and commands to decrease pressure. Users can trigger pressure adjustment commands by pressing physical buttons on the air pump or virtual buttons on the touch screen.

[0066] S260. When a pressure adjustment command is received, the standard pressure is finely adjusted according to the pressure adjustment command with a preset step size.

[0067] Specifically, when the pressure adjustment command is to increase the pressure, the controller adds a preset step size to the current standard pressure to obtain the fine-tuned standard pressure; when the pressure adjustment command is to decrease the pressure, the controller reduces the current standard pressure by a preset step size to obtain the fine-tuned standard pressure.

[0068] Specifically, the absolute value of the difference between the adjusted standard pressure and the original standard pressure (i.e., the standard pressure determined based on temperature information and a pre-stored temperature-tire pressure mapping table, also known as the original standard pressure) is less than or equal to the adjustment threshold pressure. By limiting the absolute value of the difference between the adjusted standard pressure and the original standard pressure, each pressure adjustment is a small-amplitude adjustment, avoiding over-inflation or under-inflation due to excessively large single adjustments.

[0069] The preset step size and fine-tuning threshold pressure can be set according to the inflation accuracy requirements.

[0070] In one specific embodiment, the preset step size can be set to 0.1 bar, and the fine-tuning threshold pressure can be set to 0.3 bar. This means that no matter how many consecutive adjustment commands the user issues, the deviation between the standard pressure obtained after each adjustment and the original standard pressure will be limited to within 0.3 bar, thereby achieving safe, controllable, and precise fine-tuning.

[0071] S270. After the pressure value expressed by the pressure information reaches the standard pressure, control the air pump to stop.

[0072] Specifically, after determining the standard pressure of the air pump based on temperature information and a pre-stored temperature-tire pressure mapping table, the system continuously receives mode selection commands input by the user via physical buttons or a touchscreen. Upon receiving a command to switch to a custom mode, the system controls the air pump to switch its operating mode to the custom mode. Simultaneously, the system continuously receives pressure adjustment commands input by the user via physical buttons or a touchscreen. When a pressure adjustment command is received, the system fine-tunes the current standard pressure in a preset step size according to the adjustment direction indicated by the command. The absolute value of the difference between the fine-tuned standard pressure and the original standard pressure is less than or equal to the fine-tuning threshold pressure. Subsequently, when the pressure value represented by the pressure information at the air outlet detected by the pressure sensor reaches the fine-tuned standard pressure, the system automatically stops the air pump. This satisfies the user's personalized inflation needs while effectively preventing the safety risk of over-inflation due to misoperation.

[0073] In this embodiment, during the operation of the air pump, the operating mode of the air pump and the pressure information from the pressure sensor are acquired in real time. When the air pump is operating in automatic mode, the temperature information from the first temperature sensor is also acquired. Based on the temperature information and a pre-stored temperature-tire pressure mapping table, the standard pressure of the air pump is determined. Once the pressure value expressed by the pressure information reaches the standard pressure, the air pump is controlled to stop. This allows the air pump to adaptively adjust the standard pressure according to changes in ambient temperature, avoiding the impact of thermal expansion and contraction caused by temperature changes on inflation accuracy. Furthermore, by acquiring the mode switching command input by the user via physical buttons or a touch screen in real time, and upon receiving a command to switch to a custom mode, the air pump's operating mode is switched to the custom mode. Simultaneously, the pressure adjustment command input by the user is acquired in real time. When a pressure adjustment command is received, the current standard pressure is fine-tuned according to the adjustment direction indicated by the command, with a preset step size. When the pressure value represented by the pressure information reaches the fine-tuned standard pressure, the air pump is controlled to automatically stop. This satisfies the user's personalized inflation needs while effectively preventing the safety risk of over-inflation due to misoperation.

[0074] Example 4 Figure 4 This is a flowchart illustrating a control method for an air pump according to Embodiment 4 of the present invention. This embodiment further adds a step of delayed heat dissipation after the air pump stops, based on the above embodiments. (Refer to...) Figure 4 As shown, the method specifically includes: S310. After the air pump stops, control the cooling fan to continue working and record the air pump's shutdown time.

[0075] The air pump also includes a cooling fan and a second temperature sensor, which is located on the pump's core mechanism. The air pump's controller contains a timer to record the elapsed time since the pump stopped, i.e., the downtime.

[0076] Understandably, when the air pump stops working, a lot of residual heat remains inside the mechanism. If left unattended, this will accelerate the aging of electronic components and mechanical parts.

[0077] Specifically, when the air pump receives a stop command or automatically stops after completing the inflation task, the controller does not immediately cut off the power to the cooling fan. Instead, it controls the cooling fan to continue running to force air cooling of the movement and dissipate residual heat inside the movement. At the same time, the controller records the stop time of the air pump.

[0078] S320. Determine whether the downtime meets the preset downtime conditions; if yes, execute S350; if no, execute S330.

[0079] The preset shutdown condition is that the shutdown time reaches a preset maximum heat dissipation time threshold. The maximum heat dissipation time threshold can be determined based on the performance of the air pump. For example, the maximum heat dissipation time threshold is 3 minutes. When the shutdown time of the air pump is greater than or equal to 3 minutes, the shutdown time meets the preset shutdown condition.

[0080] S330: Real-time acquisition of the air pump's operating temperature information.

[0081] The controller reads the operating temperature information of the air pump detected by the second temperature sensor installed on the movement in real time. This operating temperature information of the air pump reflects the current actual temperature of the movement.

[0082] S340: Determine whether the operating temperature information of the air pump meets the preset temperature conditions; if so, execute S350.

[0083] The preset temperature condition is that the core temperature represented by the air pump's operating temperature information is lower than a preset safe temperature threshold. The safe temperature threshold can be determined based on the performance of the air pump. For example, the safe temperature threshold is 35°C. When the temperature represented by the air pump's operating temperature information is lower than 35°C, the air pump's operating temperature information meets the preset temperature condition.

[0084] S350, controls the cooling fan to stop.

[0085] During the operation of the cooling fan, the above two conditions are continuously judged. If either of them is met (i.e., the core temperature has dropped below the preset safe temperature threshold, or the shutdown time has reached the preset maximum heat dissipation time threshold), then step S350 is executed.

[0086] Specifically, after the air pump stops, the cooling fan continues to operate and the shutdown time of the air pump is recorded. At the same time, it continuously checks whether the shutdown time meets the preset shutdown conditions. When the shutdown time meets the preset shutdown conditions, it indicates that the air pump's core has completed heat dissipation, and the cooling fan is controlled to stop. When the shutdown time does not meet the preset shutdown conditions, the operating temperature information of the second temperature sensor is also acquired in real time, and it is continuously checked whether the operating temperature information meets the preset temperature conditions. When the operating temperature information meets the preset temperature conditions, it indicates that the air pump's core has completed heat dissipation, and the cooling fan is also controlled to stop. This ensures that the core can be fully cooled, and also avoids energy waste and noise pollution caused by the fan running ineffectively for a long time.

[0087] In one optional embodiment, if the downtime meets the preset downtime conditions but the operating temperature information does not meet the preset conditions, a heat dissipation timeout reminder will be issued.

[0088] Specifically, if the downtime has reached the preset maximum heat dissipation time threshold, but the internal temperature detected by the second temperature sensor has not yet dropped below the safe temperature threshold, it indicates a possible abnormal situation such as a cooling fan malfunction, air duct blockage, or excessively high ambient temperature. In this case, a heat dissipation timeout warning signal is issued to promptly detect and alert to the heat dissipation anomaly. The heat dissipation timeout warning can be issued in at least one of the following ways: displaying text or icon prompts via the display module, flashing alarm lights, emitting an audible alert via a buzzer, or pushing notification information to the user terminal (such as a mobile app) via a wireless communication module.

[0089] In this embodiment, by recording the downtime of the air pump while the cooling fan is running and continuously judging whether the downtime meets the preset downtime conditions, if the downtime does not meet the preset downtime conditions, the operating temperature information of the air pump is also acquired in real time, and it is judged whether the operating temperature information meets the preset temperature conditions. When the operating temperature information meets the preset temperature conditions, that is, the core temperature has dropped below the safe temperature, or the downtime meets the preset downtime conditions, that is, the heat dissipation time has reached the preset upper limit, a downtime command is issued to the cooling fan to control the cooling fan to stop running, thereby ensuring that the core can dissipate heat fully, and also avoiding energy waste and noise pollution caused by the fan running ineffectively for a long time. In addition, when the downtime has reached the preset maximum heat dissipation time threshold, but the core temperature detected by the second temperature sensor has not dropped below the safe temperature threshold, a heat dissipation timeout reminder signal is issued, thereby enabling timely detection and prompting of heat dissipation abnormalities, facilitating user troubleshooting, and further improving the reliability of the equipment and user experience.

[0090] In an optional embodiment, after the interface detection element acquires the identification signal, it can also determine the preset shutdown time and / or speed of the cooling fan based on the identification signal. It is understood that since different objects being inflated have different standard air pressures, the working time of the air pump when inflating different objects also varies. When the standard air pressure of the object being inflated is higher, the air pump operates for a longer time, and the internal temperature of the air pump is also higher. In this case, the controller can extend the preset shutdown time of the cooling fan and / or increase the cooling fan speed to improve the heat dissipation effect in this usage scenario. If the standard air pressure of the object being inflated is lower, the controller can reduce the preset shutdown time of the cooling fan and / or reduce the cooling fan speed to improve heat dissipation efficiency.

[0091] The above settings enable the air pump to determine the appropriate heat dissipation scheme based on different objects being inflated, thereby improving both the heat dissipation effect and the heat dissipation efficiency.

[0092] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
