Problems solved by technology

For low-pressure inflatable products with an inflation pressure of 2Kpa ~ 6KPa, it cannot meet the needs of use
Although it is feasible to use an electronic induction device to detect the air pressure of the low-pressure inflatable products in the above range, due to the relatively expensive cost of the electronic induction device and its peripheral circuits, it cannot be widely used on ordinary inflatable products at all.

Abstract

The invention provides an air pressure detection device for detecting low air pressure. The device comprises a substrate, wherein a micro switch, a carrier rod and a pressure chamber with a deformable part are arranged on the substrate; a pressure spring and an elastic force regulating device are arranged between the carrier rod and the substrate; one end of the carrier rod tightly presses the deformable part of the pressure chamber through the pressure spring and the elastic force regulating device, and the other end of the carrier rod is tightly pressed against a button of the micro switch;a self-locking groove is formed on a rod body of the carrier rod; a self-locking pressure rod clamped into the self-locking groove and a self-locking pressure ring for pushing the self-locking pressure rod to the carrier rod are arranged between the carrier rod and the substrate; and the distance generated when the self-locking groove moves to the self-locking pressure rod is equal to the action stroke of the button of the micro switch. The air pressure detection device has a compact structure, small volume, low cost, pressure setting function and pump stopping self-locking function, can prevent an inflation pump from being frequently started under the condition of ensuring inflation pressure, and greatly prolongs the service life of the inflation pump.

Description

technical field [0001] The invention relates to an air pressure detection device on an inflatable product. Background technique [0002] The air pressure detection device for inflatable products is a device used to detect the inflation pressure and take corresponding actions when the inflation pressure reaches a predetermined value. Existing mechanical air pressure detection devices on the market, such as air pressure detection valves, generally have a detection range above 10KPa. For low-pressure inflatable products with an inflation pressure of 2KPa to 6KPa, it cannot meet the needs of use. Although it is feasible to use an electronic induction device to detect the air pressure of the above-mentioned range of low-pressure inflatable products, due to the relatively high cost of the electronic induction device and its peripheral circuits, it cannot be widely used on ordinary inflatable products at all. Therefore, there is a need for a low-cost air pressure detection device...
