Description

Technical Field

[0001] The invention relates to the technical field of air pump equipment, in particular to a portable air pump structure improvement device. Background Art

[0002] Inflatable balls such as basketballs, footballs, volleyballs, beach balls, and balloons all maintain their spherical shape with the gas filled inside, and the hardness of the ball can be determined and adjusted by the air pressure when it is inflated. However, after a period of time, the gas filled inside will inevitably dissipate due to deflation, causing the ball to be insufficiently hard or to collapse. Therefore, an inflation valve hole is usually provided at a predetermined position of the ball to allow a needle to be inserted and inflated with a pump to restore the ball to its original shape.

[0003] Since the inflation volume of this type of ball is not large, it is generally inflated with a manual simple air pump. Such air pumps are usually equipped with a cylindrical body that is suitable for holding by hand, and a ball needle interface is formed at the front end of the body. A metal screw hole is filled in the ball needle interface for threaded assembly of the ball needle, and a piston rod that can be reciprocated and pressed is inserted into the rear part of the body, and a T-handle is integrally formed or provided at the rear end of the piston rod to control the reciprocating movement of the piston rod to inject gas into the ball through the ball needle to achieve the expected inflation efficiency.

[0004] Chinese patent announcement number CN 217206765 U discloses an improved structure of a ground-mounted two-way air pump handle, comprising an air pump body, a connecting pipe installed on the left side of the air pump body, a piston rod installed on the upper end of the air pump body, a connecting column provided above the piston rod, a rotating disk rotatably connected to the connecting column, a mounting block fixedly connected to the upper end of the connecting column, mounting grooves provided on both sides of the mounting block, rotating rods rotatably connected to the front and rear inner walls of the two mounting grooves, handle rods fixedly sleeved on the two rotating rods, and two placement grooves provided on the upper end of the rotating disk. The device can synchronously lift or lower the handle rod, is simple and convenient to operate, and can effectively reduce the space occupied by the device when not in use. The first magnetic block and the second magnetic block provided can quickly fix the connecting pipe on the left side of the air pump body, thereby improving the practicality of the device.

[0005] However, the above scheme still has the following problems when it is used: the air pump in the above scheme is easily subjected to different degrees of external impact force when in use, which is easy to cause different degrees of damage to the equipment in the long run. At the same time, there are fewer scenarios for using air pumps, and the overall flexibility of the equipment is low, which cannot meet the needs of normal use, and it occupies a large amount of electronic equipment for auxiliary operations, which increases the overall use and installation cost.
