Abstract
A valve clack is provided. The valve clack includes: a mounting column (11) having a plurality of air slots (111) for dispersing an airflow at least in a top surface of the mounting column (11); a plurality of blades (12) arranged outside the mounting column (11) in a circumferential direction of the mounting column (11), each blade (12) having a radial inner end connected to the mounting column (11) and elastically swingable with respect to the mounting column (11).
Claims17
A valve clack, comprising:
- a mounting column having a plurality of air slots for dispersing an airflow at least in a top surface of the mounting column;
- a plurality of blades arranged outside the mounting column in a circumferential direction of the mounting column, each blade having a radial inner end connected to the mounting column and elastically swingable with respect to the mounting column;
- wherein each of the plurality of air slots is positioned in the top surface of the mounting column and has two open ends, the mounting column has a central part in a center thereof, in which the plurality of air slots extends outside from the central part in a radial direction, at least two of the plurality of blades are corresponding to respective one of the plurality of air slots in the circumferential direction, and radial lengths or depths of the plurality of air slots are different.
An air pump, comprising:
- an upper cover defining an air outlet;
- a valve seat disposed at a bottom of the upper cover;
- a spacer disposed between the valve seat and the upper cover and defining an air intake chamber and an air outtake chamber spaced apart from each other with the valve seat and the upper cover, the air intake chamber having an air intake passage communicated therewith, the air outtake chamber having an air outtake passage communicated therewith, the spacer having a valve clack, the valve clack comprising:
- a mounting column having a plurality of air slots for dispersing an airflow at least in a top surface of the mounting column;
- a plurality of blades arranged outside the mounting column in a circumferential direction of the mounting column, each blade having a radial inner end connected to the mounting column and elastically swingable with respect to the mounting column,
- wherein each blade is elastically swingable with respect to the mounting column, so that air flows in a one-way direction upward;
- an air intake one-way valve disposed and movable in the air intake passage so as to make the air flow in the one-way direction downward;
- a piston assembly disposed under the valve seat.
