Description

Technical Field

[0001] This utility model relates to the field of air membrane technology, specifically to an air membrane with automatic air replenishment function. Background Technology

[0002] Inflatable toys, with their lightweight texture, varied shapes, and rich colors, occupy an important position in the toy market and are widely used in children's entertainment, festival decorations, advertising, and many other fields. However, a significant drawback of most inflatable toys currently on the market is the lack of an automatic air replenishment function.

[0003] Currently, inflatable toys typically rely on manual inflation. If the internal air pressure decreases due to prolonged use, minor damage, or natural gas leakage, the air membrane can collapse and the shape can deform, significantly impacting the user experience and aesthetics. Furthermore, the lack of an automatic inflation mechanism requires frequent manual inflation, a cumbersome process, especially for children, who may find manual inflation difficult and risk damaging the air membrane due to improper operation. For larger inflatable toys, such as bouncy castles and advertising inflatables, manual inflation is not only time-consuming and labor-intensive but can also lead to structural instability and safety hazards if inflation is not timely.

[0026] The present invention will be further described in conjunction with the following embodiments.

[0027] Depend on Figures 1 to 6 As can be seen, the air membrane with automatic air replenishment function described in this embodiment includes an air membrane body 1 and an automatic air replenishment pump; the automatic air replenishment pump includes a mounting base 2; the mounting base 2 is provided with a first air chamber 21; the first air chamber 21 is provided with a positioning boss 22; the positioning boss 22 is rotatably provided with a drive seat 3; the top of the mounting base 2 is provided with a knob 23 connected to the drive seat 3; the knob 23 is provided with a ventilation groove 24 communicating with the first air chamber 21.

[0028] The drive base 3 is provided with a second air chamber 31; the drive base 3 is provided with a lower housing 4 and an upper housing 5; a third air chamber 41 communicating with the first air chamber 21 is provided between the lower housing 4 and the drive base 3; a fourth air chamber 51 is provided between the lower housing 4 and the upper housing 5; the fourth air chamber 51 is respectively connected to the second air chamber 31 and the third air chamber 41; the upper housing 5 is provided with a drive assembly;

[0029] The mounting base 2 is provided with an inflation port 61 and an air intake port 62 located inside the air film body 1; the drive base 3 is provided with a communication port 32 that communicates with the second air chamber 31; by rotating the knob 23, the communication port 32 is connected to the inflation port 61 or the air intake port 62.

[0030] The mounting base 2 is equipped with a pressure sensor 72; the pressure sensor 72 is electrically connected to the drive assembly.

[0031] Specifically, in this embodiment, the air-supported membrane with automatic air replenishment function, when the air-supported membrane body 1 needs to be inflated, rotates the rotating component to make the drive seat 3 rotate, thereby connecting the inflation port 61 with the connecting port 32. Then, the drive assembly is started. Under the action of the drive assembly, external gas enters the air-supported membrane body 1 through the ventilation groove 24, the first air chamber 21, the third air chamber 41, the fourth air chamber 51, the second air chamber 31, the connecting port 32, and the inflation port 61 in sequence, thereby inflating the air-supported membrane body 1. When the internal pressure of the air-supported membrane body 1 reaches the set upper limit value of 1400 Pa during inflation, the pressure sensor 72 receives the pressure value signal, causing the drive assembly to stop working, thereby putting the automatic air replenishment pump into standby mode. When the internal pressure of the air-supported membrane body 1 reaches the lower limit value of 1000 Pa, the pressure sensor 72 receives the pressure value and starts the drive assembly again until the upper limit value of 1400 Pa is reached and then stops operating.

[0032] In addition, when it is necessary to exhaust the air film body 1, the rotating component is rotated to make the drive seat 3 rotate so that the air inlet 62 is connected to the connecting port 32. Then the drive assembly is started to rotate in the opposite direction. Under the action of the drive assembly, the gas inside the air film body 1 is discharged after passing through the air inlet 62, the connecting port 32, the second air chamber 31, the fourth air chamber 51, the third air chamber 41, the first air chamber 21 and the ventilation groove 24 in sequence.

[0033] This embodiment describes an air-supported membrane with automatic air replenishment function. The driving component includes a motor 52 and a fan blade 53 connected to the motor 52. The motor 52 is located on the top of the upper housing 5. The fan blade 53 is rotatably located in the fourth air chamber 51. Specifically, by controlling the direction and direction of rotation of the motor 52, inflation and deflation can be achieved. The motor 52 can be a brushed motor or a brushless motor, and the motor 52 can be driven by a built-in battery or an external power source.

[0034] In this embodiment, an air-film device with automatic air replenishment function is described, wherein the bottom of the fourth air chamber 51 is connected to the third air chamber 41, and the top of the fourth air chamber 51 is connected to the second air chamber 31. This configuration allows for smoother gas flow.

This configuration protects the pressure sensor 72 while allowing it to effectively sense the air pressure of the air-supported membrane body 1.

[0038] The air-supported membrane with automatic air replenishment function described in this embodiment is provided with a one-way valve 63 at the air inlet 61. This design prevents gas inside the air-supported membrane body 1 from flowing out of the air inlet 61.

[0039] In this embodiment, an air-supported membrane with automatic air replenishment function is provided, wherein both the inflation port 61 and the intake port 62 are connected to a sealing ring 64; the top of the sealing ring 64 abuts against the bottom of the drive seat 3. This arrangement ensures the airtightness between the inflation port 61, the intake port 62, and the first air chamber 21.

[0040] The air-supported membrane with automatic air replenishment function described in this embodiment has an on / off switch 8 on the top of the mounting base 2. The air inflation function can be manually switched to the inflation mode. Pressing the on / off switch 8 starts inflation, and the system automatically switches to the air replenishment mode after inflation stops.

[0041] This embodiment describes an air-supported membrane with automatic air replenishment function. The mounting base 2 is equipped with a lamp wire interface. The lamp wire interface is not shown in the figure, but this design facilitates the connection of an external LED light.
