CONSTANT-AIR-VOLUME AIR OUTPUT DEVICE AND AIR PUMP DEVICE HAVING SAME, AND TOILET
Document Type and Number:
WIPO Patent Application WO/2024/082547
Kind Code:
A1
Abstract:
Disclosed in the present invention are a constant-air-volume air output device and an air pump device having same, and a toilet. The constant-air-volume air output device comprises: a body, which is provided with an inner cavity, an air inlet and an air outlet, and in which a limiting structure is provided; and a valve core unit, which is arranged in the body and divides the inner cavity of the body into a driving cavity and an air output cavity in a sealing manner, wherein the driving cavity communicates with the air inlet, the air output cavity communicates with the air outlet, and the valve core unit is in sealed sliding fit with an inner wall of the body; and the limiting structure can be in limiting fit with the valve core unit to limit the movement stroke of the valve core unit. When an air supply source supplies pressurized air to the driving cavity through the air inlet to drive the valve core unit to move, the valve core unit presses the air in the air output cavity and pushes the air out of the air outlet, and the movement stroke of the valve core unit is limited by means of the limiting structure to enable the valve core unit to move at a fixed stroke, so as to achieve constant-air-volume air output from the air output cavity through the air outlet.
