Description

Technical Field

[0001] This utility model relates to the field of air pump technology, and in particular to an air pump mechanism capable of measuring gas pressure. Background Technology

[0002] An air inflator is also called an air pump or air compressor. When the motor runs and air is drawn in, the valve of the inflator is opened by atmospheric pressure, allowing air to enter the cylinder. When air is pumped into the device being inflated, the valve is closed by the pressure inside the cylinder, allowing air to enter the device.

[0003] The air pump mechanism consists of a cooling fan, a motor, a gear transmission mechanism, a piston assembly, and a bracket. The motor, the cylinder of the piston assembly, and the bracket are connected by bolts. In common air pump mechanisms, the angle between the motor, the cylinder of the piston assembly, and the bracket needs to be adjusted during assembly; otherwise, the bolts cannot be installed. Adjusting the position of the motor, the cylinder of the piston assembly, and the bracket will reduce the installation efficiency of the air pump mechanism. Utility Model Content

[0022] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0023] Working principle: After the motor 1 starts, one output shaft drives the fan 2 to rotate for heat dissipation. The bevel gear 23 installed on the other output shaft meshes with the lower gear surface of the reduction gear 8, transmitting the rotational motion of the motor 1 to the reduction gear 8. The connecting rod shaft 24 set at the upper end of the reduction gear 8 is connected to the transmission connecting rod 7 through the bearing 21, so that when the reduction gear 8 rotates, it drives the transmission connecting rod 7 to make planar motion. The piston part of the transmission connecting rod 7 forms a reciprocating linear motion in the cylinder 6. When the piston moves towards the bracket 3 in the cylinder 6, a negative pressure is formed in the cylinder 6, the air inlet valve 19 opens, and external air is drawn into the cylinder 6 through the channel in the transmission connecting rod 7. When the piston moves towards the air outlet 5, the air inlet valve 19 closes, the air is compressed, the pressure increases, pushing the check plate 18 to open, and the compressed air enters the air outlet 5. The compressed air enters the connecting throat 13 from the air outlet 5, and finally reaches the pressure gauge 20. The air pressure sensor 10 detects the air pressure.
