Technical Field
[0001] This utility model relates to the field of balloon inflation pump technology, specifically to a miniature handheld balloon inflation pump. Background Technology
[0002] A balloon inflator is a convenient inflator specifically designed to inject gas into balloons to achieve inflation and shape. Its core function is to replace the traditional blowing method, compressing and stably delivering gas into the balloon through mechanical or electric drive, meeting the needs of balloons in decoration, celebrations, events and other scenarios.
[0003] Currently, some balloon inflators on the market are quite large, making them inconvenient to carry and taking up a lot of space during use. Moreover, their maximum inflation pressure is only 10 kPa, which cannot meet the needs of users.
[0004] To address the aforementioned issues, this application proposes a miniature handheld balloon inflator. Utility Model Content

A rotating shaft is installed at the output end of the brushless motor. A third blade is installed after the top end of the rotating shaft passes through a third wind guide plate. The third wind guide plate is connected to the air inlet. A second lower air guide plate is installed above the third blade, and a second inlet air guide plate is installed above the second lower air guide plate.
[0009] As a further embodiment of this utility model, the rotating shaft passes through the second lower air guide plate and the second inlet air guide plate in sequence and is then fitted with a second blade. A first lower air guide plate is installed above the second blade, and a first inlet air guide plate is installed above the first lower air guide plate.

[0026] Please refer to the instruction manual appendix. Figure 1-5According to an embodiment of the present invention, a miniature handheld balloon inflator includes a main housing 1. A battery assembly 2 is installed in the inner cavity of the main housing 1. The battery assembly 2 is electrically connected to a PCB control board 3 in the inner cavity of the main housing 1. An illumination lamp 4 is provided on the PCB control board 3. The illumination lamp 4 is used in conjunction with a lampshade 5 on the outer wall of the main housing 1. A part of a paddle assembly 6 is installed between the battery assembly 2 and the PCB control board 3. A top shell 7 is installed at the top of the main housing 1. A hook 8 is installed on the upper surface of the top shell 7. An inflation port 9 is connected to the side wall of the main housing 1. The rear end of the inflation port 9 is used in conjunction with a part of the paddle assembly 6. An air nozzle 10 is inserted into the inflation port 9. The air nozzle 10 is provided in three specifications. The paddle assembly 6 includes a brushless motor 61. The brushless motor 61 is located between the battery assembly 2 and the PCB control board 3. Between the CB control boards 3, a rotating shaft 62 is installed at the output end of the brushless motor 61. The top end of the rotating shaft 62 passes through the third air guide plate 63 and is then fitted with a third blade 64. The third air guide plate 63 is connected to the air inlet 9. A second lower air guide plate 65 is installed above the third blade 64. A second inlet air guide plate 66 is installed above the second lower air guide plate 65. The rotating shaft 62 passes through the second lower air guide plate 65 and the second inlet air guide plate 66 in sequence and is then fitted with a second blade 67. A first lower air guide plate 68 is installed above the second blade 67. A first inlet air guide plate 69 is installed above the first lower air guide plate 68. A first blade 610 is provided on the first inlet air guide plate 69 and is drivenly mounted on the rotating shaft 62. A top shell 7 is installed above the first blade 610, and an air inlet 11 is provided on the top shell 7. By centrally housing the miniaturized battery assembly 2 and the propeller assembly 6 within the inner cavity of the main housing 1, the air pump can be miniaturized, reducing its size and making it easy to carry. Furthermore, the brushless motor 61 uses a three-layer propeller pressurization system to pressurize the incoming gas. During operation, the first propeller 610 draws in air through the air inlet 11. The incoming gas, under the action of the first propeller 610, is then discharged through the exhaust port at the left end of the first air guide plate 69, and then enters the second propeller 67 through the opening in the middle of the first lower air guide plate 68. Subsequently, under the action of the second propeller 67, the gas is discharged through the exhaust port at the left end of the second air guide plate 66, and then enters the third propeller 64 through the opening in the middle of the second lower air guide plate 65. Under the action of the third propeller 64, the gas is discharged from the air inlet 9 on the side wall of the main housing 1. The incoming gas, after being pressurized by the three layers of propellers, can reach 12 kPa, enabling the air pump to achieve its maximum inflation pressure and meet usage requirements.
[0027] The included light 4 allows the air pump to be used in poor lighting conditions, while the included hook 8 makes it easy to carry and store the air pump.

Figure 1 , Figure 2 and Figure 3 As a further embodiment of this invention, the PCB control board 3 is also used in conjunction with the switch button 12 and the waterproof silicone 13 for the charging port on the outer wall of the main housing 1. The switch button 12 facilitates control of the air pump, while the waterproof silicone 13 for the charging port provides waterproof protection for the charging port on the PCB control board 3.
[0030] Workflow: In use, first select the appropriate size of nozzle 10 according to the requirements and plug it into the inflation port 9. Then connect the balloon to the nozzle 10 and start the brushless motor 61 by pressing the switch button 12 to start the inflation operation. During this process, the first blade 610 draws in air from the air inlet 11. The air then enters the second blade 67 through the opening in the middle of the first air guide plate 68 under the action of the first blade 610. The air then enters the third blade 64 through the opening in the middle of the second air guide plate 65 under the action of the third blade 64.
