Description

Technical Field

[0001] The present invention relates to the technical field of inflatable equipment, and in particular to an electric air pump based on parameter analysis and prediction. Background Art

[0002] At present, in daily life and industrial production, electric air pumps are widely used as an important equipment for tire inflation, balloon inflation, swimming ring inflation, and various equipment and products that require gas filling. However, when using electric air pumps for inflation operations, ensuring the accuracy and efficiency of the inflation process has become a key issue. When traditional electric air pumps are inflated, due to the inaccurate control system, they cannot output accurately at one time and require secondary air replenishment. During the initial compression, the required air pressure cannot be reached at one time, resulting in low efficiency. Therefore, how to efficiently control the electric air pump for one-time inflation has become an imminent problem for electric air pumps.

[0003] However, the existing electric air pump only solves the problem that the electric air pump has no air suction function by receiving the signal from the pressure sensor and controlling the solenoid valve to switch between the first state and the second state. It does not consider the efficient one-time inflation of the electric air pump by accurately calculating the predicted inflation time and predicted control parameters of the electric air pump, and does not avoid overcharging or undercharging. For example, the patent with the publication number of "CN115929598A" and the name of the patent "Electric air pump and control method of electric air pump" includes the following steps: a shell, an air extraction port is provided on the shell; a heat dissipation duct is formed inside the shell; a cylinder is provided inside the shell, and the air intake port of the cylinder is connected to the air extraction port; a heat dissipation fan is provided in the heat dissipation duct; the air intake end of the heat dissipation duct is connected to the air extraction port; a solenoid valve, the solenoid valve is used to control the connection and isolation between the air intake end of the heat dissipation duct and the air extraction port; the solenoid valve has a first state for controlling the connection between the air intake end of the heat dissipation duct and the air extraction port, and the solenoid valve has a second state for controlling the isolation between the air intake end of the heat dissipation duct and the air extraction port; a pressure sensor is used to detect the air intake pressure of the cylinder; a controller is used to receive the signal of the pressure sensor and control the solenoid valve to switch between the first state and the second state. The above patent effectively solves the problem that the electric air pump in the prior art has no air extraction function and is not smart enough. However, this patent only solves the problem that the electric air pump has no air extraction function by receiving the signal from the pressure sensor and controlling the solenoid valve to switch between the first state and the second state. It does not consider the efficient one-time inflation of the electric air pump by accurately calculating the predicted inflation time and predicted control parameters of the electric air pump, and does not avoid overcharging or undercharging.

[0004] Therefore, the present invention proposes an electric air pump based on parameter analysis prediction. Summary of the invention
