Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to an inflatable fan. Background Technology

[0002] Currently, inflatable blowers are widely used for inflating products such as tires, inflatable pools, tents, and surfboards. However, to ensure inflation efficiency, existing inflatable blowers typically have an external pressure gauge connected to the air outlet. This external gauge, with its numerous connection points and poor sealing, often causes the air pressure to gradually drop after inflation stops due to valve leaks or pipe leaks. This necessitates frequent refills, causing inconvenience, especially for long-term use of large inflatable products (such as inflatable pools). Furthermore, poor airtightness prevents the gauge from accurately displaying the air pressure inside the inflatable object, resulting in insufficient pressure control precision and impacting efficiency. Utility Model Content

Furthermore, while ensuring airtightness, a pressure detection element 51 is installed on the shell structure 2 relative to the air outlet end of the blower body 1, ensuring accurate detection data and effectively improving the inflation pressure control precision of the blower. To achieve these objectives, the shell structure 2 includes a mounting cavity 31 for sealing and installing the blower body 1, preventing air leakage. The mounting cavity 31 has a mounting end 33 facing the air outlet end of the blower body 1. Inflation pipes for connecting external structures to be inflated can be sealed to the mounting end 33 via an interference fit. A snap-fit ​​component can be provided on the mounting end 33 to further ensure the connection stability between the external inflation pipes and the mounting end 33.

[0034] A one-way valve 7 is also provided in the mounting cavity 31. One end of the one-way valve 7 is connected to the air outlet end of the blower body 1, and the other end is connected to the mounting end 33. The one-way valve 7 is located in the mounting cavity 31, which can further improve the sealing performance of the air-filling blower and prevent the gas in the air-filling structure from flowing back after the blower body 1 stops. In addition, the one-way valve 7 is located in the mounting cavity 31, which can also make the air pressure fluctuation in the mounting cavity 31 more stable, and can effectively improve the detection accuracy of the air pressure detection element 51.

[0035] The shell structure 2 is equipped with a control motherboard 5, which is electrically connected to the blower body 1. The control motherboard 5 is also equipped with a power module. The control motherboard 5 can control the air pressure output rate, maximum inflation pressure and other inflation coefficients according to the user's pre-input values ​​on the control component 53.

[0040] The inner shell 3 has a pressure detection hole 34 that connects to the mounting cavity. After the fan body 1 is installed, its air outlet will be connected to the pressure detection hole 34. An air pipe (usually a silicone tube) connected to the pressure detection component 51 can be installed through the pressure detection hole 34. This allows the control motherboard 5 to identify the air pressure in the pressure detection hole 34 through the pressure detection component 51.

The air pressure detection hole 34 is located on the outer periphery of the air mold chamber. The one-way valve itself is located in the pressure stabilizing chamber, which can prevent gas from flowing back from the part to be inflated after inflation stops. The first sealing ring and the second sealing ring work together to prevent the inflation blower itself from leaking. All the structures together form an air mold chamber that can prevent air leakage. By connecting the inflation pipe to the outside of the air mold chamber, the inflation pressure can be ensured to reach the value set by the user stably, and air leakage can be prevented after inflation stops.

[0046] In one feasible embodiment, the mounting cavity 31 itself can be divided into a sealed cavity that is completely fitted to the fan body 1 away from its air inlet. The mounting cavity 31 has a pressure stabilizing cavity between the sealed cavity and the mounting end 33. The pressure stabilizing cavity has a connecting part relative to the mounting end 33.

A filter screen 62 is provided between the connecting end 61 and the air inlet of the fan body 1. The air inlet can be filtered through the filter screen 62 to reduce impurities in the gas passing through the fan body 1 and effectively reduce the wear of the fan body 1.

Of course, in order to protect the inflation blower and avoid safety hazards during use, the control main board 5 can be equipped with an alarm.

[0050] Preferably, the mounting part 41 has a plurality of limiting connecting posts 42 arrayed on it, and the control motherboard 5 has a plurality of clearance slots relative to the limiting connecting posts 42.

Using the remote connection unit 54, users can remotely view the current output status and working status of the blower without using the display component 52 and control component 53, but using external wireless devices such as mobile phones. It can also control the start / stop of the inflation blower, adjust the upper and lower limits of the blower's output air pressure, and adjust the blower to enter the start / stop inflation mode or start / stop exhaust mode, which can effectively improve the user experience.

[0053] Preferably, the outer casing 4 and / or control casing 43 are provided with handles, making the inflator itself easy to move and carry.

[0054] Preferably, the outer casing 4 has multiple support structures on the side away from the mounting part 41.
