Abstract

The invention discloses an inflation pump. The inflation pump comprises a shell, a driving piece, a gear transmission assembly, a piston rod and an air cylinder; the piston rod is provided with a pushing part, and the piston rod can push a piston sealing ring to move towards the air cylinder through the pushing part; the pushing part comprises a first pushing surface and a second pushing surface,and a height difference is formed at the position where the first pushing surface is connected with the second pushing surface; and when the piston sealing ring acts on the first pushing surface and the second pushing surface, an air leakage channel is formed between the piston sealing ring and the first pushing surface and the second pushing surface. According to the inflation pump, the air leakage channel is formed between the piston sealing ring and the pushing part so as to release the pressure of gas pushed by the piston sealing ring, thus, the piston rod can drive the piston sealing ringto move towards the cylinder, when the back pressure of the inflation pump is started, the acting force of pushing the piston rod again is reduced, the effect of reducing the rated voltage of the driving piece on the inflation pump is achieved, and the application range of the inflation pump is expanded.

Description

technical field [0001] The invention belongs to the related technical field of vehicle inflation, and in particular relates to an air pump. Background technique [0002] The air pump is also called inflator, air pump, and the air pump works through the operation of the motor. When the motor is running, the valve of the connector is opened by the atmospheric pressure, and the gas enters the air cylinder. When the air is pumped into the tire, the valve is closed again. The air pressure in the cylinder is turned off, and the gas enters the tire. [0003] At present, the rated voltage of the motor on the existing air pump is relatively high, and the rated voltage of the motor is usually 5V or above, so as to ensure that when the air pump starts with back pressure, the motor can continue to drive the piston rod under the transmission of the gear transmission assembly. Movement in the direction of the cylinder, i.e. ensuring that the air pump can be activated against back pressur...
