Description

Air pump with double power supply modes and control method thereof Technical Field The invention relates to the technical field of sampling devices, in particular to an air pump with double power supply modes and a control method thereof. Background Along with the popularization of outdoor activities and self-driving travel, the demand of the multifunctional portable air pump is growing. At present, a dual-purpose air pump capable of inflating high-pressure large-volume objects (such as more than 60 PSI) such as truck tires and the like and inflating low-pressure large-volume objects (such as 0-20 PSI) such as paddles and air cushions exists in the market. To achieve the high flow rates and high power required for high pressure, high volume inflation, such products are typically powered by high discharge capacity built-in batteries (cells). The 'power consumption anxiety' of the user is relieved, the service time is prolonged or the condition of battery power exhaustion is dealt with, and part of products try to increase the cigar lighter power supply interface. However, the vehicle cigar lighter interface has limited load carrying capacity, typically rated at about 120W (12 v,10 a). If the air pump still tries to combine the two working conditions of low-pressure large flow and high-pressure large flow in the cigar lighter power supply mode, limited 120W power must be distributed between a high-pressure region and a low-pressure region. This can result in the maximum power actually achieved by the pump core being well below its design capacity during low pressure inflation (e.g., paddle) resulting in an extremely slow inflation rate and poor user experience, such that the function behaves like a dummy. Therefore, how to ensure the practicability and the user experience of the cigar lighter under the typical application scene (especially low-pressure inflation) while introducing the convenient function of cigar lighter power supply is a technical problem to be solved urgently in the field.
