A kind of micro inflatable core

Abstract

The invention relates to the technical field of inflatable pumps, in particular to a miniature inflatable core, including a bracket, one end of the bracket is connected with a drive motor, the output shaft of the drive motor is connected with a motor gear, and the other end of the bracket is connected with a rotatable reduction gear. The reduction gear is connected to the inflatable component, and the transmission belt is connected between the motor gear and the reduction gear. The motor gear driving the motor drives the transmission belt to rotate, and the transmission belt drives the reduction gear to rotate. The rotating reduction gear drives the inflatable component to inflate, which is realized through the transmission belt. Reduce the rotation of the gear, so as to avoid the collision between the reduction gear and the motor gear, reduce the working noise of the movement, reduce the vibration and wear of the gear, and prolong the working life of the inflatable movement; the cam mechanism, piston connecting rod, cylinder and The cylinder head is located on one side of the drive motor, and the cylinder head is located between the drive motor and the cylinder, which makes the structure of the movement more compact and improves the heat dissipation performance of the movement.

Description

technical field [0001] The invention relates to the technical field of air pumps, in particular to a miniature air-inflating core. Background technique [0002] Air pump, also known as air pump, air pump or inflator, works through the operation of a motor and is an electric inflatable tool. The working principle of the air pump is: power on to make the motor run, when pumping air, the check valve of the piston is opened by the atmospheric pressure, the gas enters the air cylinder, and when the tire is inflated, the check valve is closed by the air pressure in the air cylinder , the compressed gas enters the tire. At present, air pumps are widely used in fields such as automobiles, magic motorcycles, bicycles, rubber balls, and rubber boats. [0003] The connection structure of the existing air pump core generally includes a core motor, a core bracket, a reduction gear and a support shaft. The core motor is arranged on the core bracket, and the output end of the core motor ...

AI Technical Summary

Problems solved by technology

There are many problems in the existing air pump core, among which, the noise problem is more prominent, because the motor gear and the reduction gear in the air pump core will collide with each other during the working process, resulting in relatively large noise , greatly reducing the consumer experience

What's more serious is that after long-time work caused by vibration and wear, the reduction gear may fall off the motor gear in the axial direction, resulting in product failure, low reliability of the movement, and short service life

[0004] In addition, the main parts of the existing air pump core that need heat dissipation include the core motor, cylinder and cylinder head. Since the rear end of the core motor is connected to a fan, the fan can dissipate heat from the motor in time, but the distance between the cylinder and the cylinder head for heat dissipation Farther away often leads to poor heat dissipation effect of the cylinder and cylinder head, thus affecting the service life of the air pump core
