Abstract
A miniature pump includes a cylinder, a piston module, a driving module and a wall body. The cylinder has a first end and a second end opposite to each other along a direction. The piston module is accommodated in the cylinder. The piston module has at least one pumping chamber structure protruded towards the second end, and the pumping chamber structure is able to extend or retract along the direction. The driving module is located at the second end and connected to the pumping chamber structure, configured to drive the pumping chamber structure to extend or retract along the direction. The wall body at least partially surrounds a position of the pumping chamber structure near the first end, and is located between the cylinder and the pumping chamber structure.
Claims18
A miniature pump, comprising:
- a cylinder having a first end and a second end opposite to each other along a direction;
- a piston module accommodated in the cylinder, the piston module having at least one pumping chamber structure protruded towards the second end, and the pumping chamber structure being able to extend or retract along the direction;
- a driving module located at the second end and connected to the pumping chamber structure, being configured to drive the pumping chamber structure to extend or retract along the direction;
- and
- a wall body at least partially surrounding a position of the pumping chamber structure near the first end, and located between the cylinder and the pumping chamber structure.
A miniature pump, comprising:
- a cylinder having a first end and a second end opposite to each other along a direction, the cylinder having a cylinder plate and the cylinder plate having at least one air intake hole;
- and
- a piston module accommodated in the cylinder, the piston module comprising:
- a plate portion stacked on a side of the cylinder plate facing the first end, the plate portion having a plate main body and at least one air intake valve piece, the air intake valve piece covering and sealing the air intake hole, and the air intake valve piece having:
- a root connected to the plate main body, the air intake valve piece tilting towards the first end about the root;
- and
- an edge composed of two straight-line sections, two curved sections and a circular section, wherein the two straight-line sections are respectively connected to the two opposite ends of the root, the two curved sections are respectively connected to the straight-line sections, and the circular section is connected to the curved sections.
