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).

Abstract: An air pump is provided. An air pump includes an upper cover, a valve seat, a spacer, an air intake one-way valve and a piston assembly. The upper cover has an air outlet. The valve seat is disposed on a bottom of the upper cover. The spacer is disposed between the valve seat and the upper cover and has an air intake chamber and an air outtake chamber. The air intake chamber has an air intake passage communicated therewith, and the air outtake chamber having an air outtake passage communicated therewith. The spacer has a valve clack, so that air flows in a one-way direction from bottom to top. The air intake one-way valve is disposed and movable in the air intake passage so as to make the air flow in the one-way direction from top to bottom. The piston assembly is disposed under the valve seat.

Abstract: A valve clack and an air pump having the same are provided. The valve clack includes a mounting column; a plurality of blades surrounding the mounting column and distributed in a circumferential direction of the mounting column, each blade defining a radial inner end connected with the mounting column and elastically swingable with respect to the mounting column, adjacent blades being spaced apart from each other by a rib, the rib defining an end connected with the mounting column, a buffer structure configured to provide a buffer space for deformation of the blade being provided in the blade adjacent to a position at which the blade is connected with the rib.

Abstract: Provided is an electromagnetic linear valve that includes a main valve body having an upper valve body and a lower valve body. The upper valve body and the lower valve body are connected together by ultrasonic welding. The lower valve body comprises a frame. The electromagnetic linear valve includes a spring leaf and a movable element. An electromagnetic unit drives the movable element in the valve body, and the electromagnetic unit includes a steel casing that is fixed to the frame. A baffle divides the valve body into upper and lower valve chambers. The upper valve chamber has an inlet vent and an outlet vent. A through hole is formed in the baffle to connect the upper and lower valve chambers. The movable element has a valve plug blocking the through hole on the baffle.

Abstract: An electromagnetic linear valve comprises a valve body, a movable element and an electromagnetic unit driving the movable element in the valve body and a spring leaf, wherein said valve body is divided into two valve chambers by a baffle where a through hole is formed to make the two valve chambers connected, and two valve chambers have an air inlet vent and an exhaust vent respectively, and the movable element has a valve plug blocking the through hole on the baffle, and the said valve body comprises a upper valve body and a lower valve body wherein said upper valve body and lower valve body are connected by ultrasonic welding. The upper valve body and the lower valve body of the present invention are connected by ultrasonic welding so that the connection is tight, stable, and the damage of other components caused by rotating a bolt in the assembling process is avoided.
