Abstract
A pressure switch configured to be disposed on a path, through which dust passes, to control a dust sensor according to whether a suction pressure is formed in the path, is provided. The pressure switch includes: a body part having a connection tube connected to the path, and an upper surface; first and second terminals configured to be electrically connected to the dust sensor, and at least a portion of which protrudes from the upper surface of the body part; and a flexible cap configured to engage the body part to define a space along with the upper surface of the body part. The flexible cap is deformed in response to a negative pressure being formed in the space, thereby electrically connecting the first and second terminals.

A pressure switch configured to be disposed on a path through which dust passes, to control a dust sensor according to whether a suction pressure is formed in the path, the pressure switch comprising:
- a body part having a connection tube connected to the path, and an upper surface;
- first and second terminals configured to be electrically connected to the dust sensor and comprise upper ends protruding from the upper surface of the body part;
- and
- a flexible cap configured to engage the body part, and define a space with the upper surface of the body part;
- and
- wherein the flexible cap is deformed in response to a negative pressure being formed in the space to electrically connect the first and second terminals.
A pressure switch configured to be disposed on a path through which dust passes, to control a dust sensor according to whether a suction pressure is formed in the path, the pressure switch comprising:
- a body part having a connection tube connected to the path and comprising an upper surface in which a flow groove is formed to be connected to the connection tube;
- first and second terminals configured to be electrically connected to the dust sensor, and having respective ends protruding from the upper surface of the body part, the respective ends having different heights when measured from the upper surface;
- and
- a flexible cap configured to engage the body part to define a space with the upper surface of the body part and comprising a conductive member therein to be electively connected to the first and second terminals,
- wherein the conductive member is connected to the first and second terminals in response to the flexible cap being deformed when a negative pressure is formed in the space.
A vacuum cleaner comprising:
- a cleaner body configured to comprise a suction source;
- a suction nozzle configured to suck dust;
- an extension tube configured to connect the cleaner body to the suction nozzle;
- and
- a pressure switch configured to be disposed at the extension tube to control a dust sensor according to whether a suction pressure is formed in the extension tube,
- wherein the pressure switch comprises:
- a body part having a connection part connected to the extension tube and an upper surface;
- first and second terminals configured to be electrically connected to the dust sensor and comprising upper ends that protrude to different heights from the upper surface of the body part;
- a flexible cap configured to engage the body part to define a space with the upper surface of the body part and comprising a conductive member therein to be connectable to the first and second terminals, and
- wherein the flexible cap shrinks in response to a negative pressure being formed in the space, thereby connecting the conductive member to the first and second terminals.
