The sensing device may For a simple contact switch, it is installed in the opening 28, and when it is attached to the opening 28, it is turned on by the movement of the charging input screw. Or, the sensing device may be, for example, a Hall (Hall) installed in the opening 28 ) The effect device is triggered by approaching a magnet mounted on the inflation input. The control circuit 23 is configured as a device well known in the art as a self-sensing device 24 that has detected the opening 28 and the double air valve When the inflation input is engaged, power is transmitted to the motor 25. In this way, the air is only pumped into the cooked area immediately after the inflation device 20 has been properly engaged. Similarly, the control circuit is configured to stop when the inflation device 20 is no longer engaged Power transmission, so it can be easily turned on and off without an external switch. When the inflation device 20 is engaged with the pad, the control circuit 23 continues to transmit power to the motor 25 until a predetermined condition is reached. In this embodiment, a type of battery The motor impeller assembly is designed to provide a maximum air pressure that does not exceed the maximum desired pressure in the pad.

Description of invention (5) Stop power transmission to the motor 25. General air cushion The general design of the gas-filled device, for example, can reach the maximum pressure in about one minute, so the control circuit provides a timed disconnection after one minute. The timed disconnection feature obviously provides a suitable battery power retention. When full inflation occurs, it is in The inflator has first reached the maximum possible pressure of the air cushion (assuming this maximum value does not exceed the maximum desired pressure in the cushion) and can enhance power retention. Indeed, this method allows the use of smaller and lighter inflator. If the user provides the last small amount of air manually (such as blowing) to achieve the desired pressure, the inflator can be smaller. This design eliminates the need for the user to manually inflate the pad, which takes time and headaches, while allowing the compact and lightweight construction of the inflatable balloon 20. Or, the control can use the flow that has reached the maximum desired pressure (assuming that the battery motor impeller assembly is designed to provide the maximum gas pressure not exceeding the maximum pressure in the pad), and actually stop the inflation input from the inflation device 20 to the dual valve 12. In this alternative configuration, the inflation device 20 may be additionally provided with a flow rate detector, and the control circuit 23 may be pre-configured to stop the electrical power after the actual airflow stops. In a flow sensor of this configuration, a leaf H (shown in phantom) 201 is mounted on a pivot Z02 and has an arm 203.

The depression of the rod 31 causes the diaphragm to move downward away from the valve seat 36 and allows the control air to flow out through the passage 17, which can temporarily exceed this seal. Therefore, the valve design can reduce any excess air pressure that occurs during inflation in the tank to the desired optimal force, as long as it is under the rod 31®. The amount of air released by the valve can be controlled by the distance at which the valve stem 31 is initially depressed (so that the air pressure in the base 10 forces the valve back to the open and closed position); for example, a small decrease in the pressure provided by the eighth inch, Depressing one-half inch provides a larger amount of E drop. It should be noted that the M described in this article generally functions at a pressure of about 1/4 to 1 psi (2 to 7 kilopascals), and it is generally difficult to seal with an effective seal at this location «To good control. The diameter of the first cylinder 32 is large enough (typically about 1.25 inches (3 cm) or more) to allow the cushion to inflate rapidly with a large amount of airflow at a low overall force.

Although the embodiments shown in this article illustrate the use of hinges 35 and latches 36, but I can see. », Other devices known in the art can be used to fix the bayonet after rotation attachment In order to cover the second cylinder 33, the valve assembly described above is fixed. Alternatively, a combined bayonet hinge assembly may be used, configured so that after the bayonet is disengaged by reverse rotation, a grenade shaft (similar to component 35, but supported on a short mount to the second cylinder On the curved track, the bayonet is allowed to rotate) allowing the valve assembly to open the opening defined by the edge 38 in a manner similar to that described above. The outer shell of the second cylinder is provided with multi-bearing support 331 to prevent the inner surface of the pad 10. The surface completely closes the opening of the second cylinder 33 to the inside of the pad, allowing unrestricted airflow when the air cushion is flattened or nearly flattened Into it (or out of it). Similarly, a series of openings 323 at the end of the i-cylinder 32 prevents the inner surface of the pad 10 from completely closing the opening from the first cylinder to the inside of the pad.
