Description

Technical Field

[0001] The present invention relates to the technical field of inflating devices, and particularly to an electric air pump based on parameter analysis and prediction. Background Art

[0002] Currently, in daily life and industrial production, as an important device, electric air pumps are widely used in tire inflation, balloon inflation, swimming ring inflation, and various devices and products that require gas filling. However, when using an electric air pump for inflation operations, ensuring the accuracy and efficiency of the inflation process has become a key issue. When traditional electric air pumps inflate, due to the imprecise control system, they cannot output accurately at one time and need secondary air replenishment. They cannot reach the required air pressure in one go during the initial compression, resulting in low efficiency. Therefore, how to efficiently control an electric air pump for one-time inflation has become an urgent problem for current electric air pumps.

[0003] However, existing electric air pumps only solve the problem of the electric air pump not having a pumping function by receiving the signal of a pressure sensor and controlling the solenoid valve to switch between a first state and a second state, without considering efficiently achieving one-time inflation of the electric air pump by precisely calculating the predicted inflation duration and predicted control parameters of the electric air pump, and without avoiding over-inflation or under-inflation. For example, the patent with the publication number "CN115929598A" and the patent name "Electric Air Pump and Control Method of Electric Air Pump", the method includes the following steps: a housing with an air extraction port provided thereon; a heat dissipation air duct formed inside the housing; a cylinder disposed inside the housing, and the air suction port of the cylinder is communicated with the air extraction port; a heat dissipation fan disposed in the heat dissipation air duct; the air inlet end of the heat dissipation air duct is communicated with the air extraction port; a solenoid valve for controlling the communication and disconnection between the air inlet end of the heat dissipation air duct and the air extraction port; the solenoid valve has a first state for controlling the communication between the air inlet end of the heat dissipation air duct and the air extraction port, and the solenoid valve has a second state for controlling the disconnection between the air inlet end of the heat dissipation air duct and the air extraction port; a pressure sensor for detecting the air suction pressure of the cylinder; a controller for receiving the signal of the pressure sensor and controlling the solenoid valve to switch between the first state and the second state. The above patent effectively solves the problems that the existing electric air pump does not have a pumping function and is not intelligent enough. However, this patent only solves the problem of the electric air pump not having a pumping function by receiving the signal of the pressure sensor and controlling the solenoid valve to switch between the first state and the second state, without considering efficiently achieving one-time inflation of the electric air pump by precisely calculating the predicted inflation duration and predicted control parameters of the electric air pump, and without avoiding over-inflation or under-inflation.

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