Abstract

A vacuum cleaner of the present invention comprises: a main body having a suction motor for generating suction force; a main PCB capable of generating a control command for the suction motor; a handle part capable of accommodating the main body PCB; and a connector provided at the main body, and to which the main PCB is connected in a process of coupling the handle part to the main body. The main PCB includes a plurality of pads and a slit, and the connector includes: a plurality of connecting pins for making contact with the plurality of pads; and a slit insertion protrusion inserted into the slit.

First claim

1 . A cleaner comprising:
a main body comprising:
a suction motor configured to generate suction force, and
a dust separator configured to separate dust from air using a cyclone flow, wherein the dust separator and the suction motor are arranged in a first direction parallel to an axis of the cyclonic flow;
a Printed Circuit Board (PCB) configured to generate a control command of the suction motor; a handle part that accommodates the PCB and that is configured to couple to the main body in the first direction; and a connector located at the main body, wherein the PCB is configured to couple to the connector based on the handle part moving along the outer surface of the main body in the first direction.

2 . The cleaner of claim 1 , wherein the axis of the cyclonic flow extends in a vertical direction.

3 . The cleaner of claim 1 , wherein the main body comprises a suction unit configured to guide air containing dust into the dust separator, and
the connector is positioned higher than the suction unit.

4 . The cleaner of claim 1 , wherein the main body comprises a connector support configured to support the connector.

5 . The cleaner of claim 4 , wherein the main body further comprises a stopper rib for preventing the connector supported by the connector support from separating upward.

6 . The cleaner of claim 4 , wherein the stopper rib is spaced from the connector support, and the connector is inserted in the space between the connector support and the stopper rib.

7 . The cleaner of claim 5 , wherein the connector is horizontally slid on the connector support.

8 . The cleaner of claim 1 , wherein the connector comprises:
first and second connecting bodies spaced apart from each other; a bridge body configured to connect a lower side of the first connecting body to a lower side of the second connecting body; and a PCB receiving space defined between the first connecting body and the second connecting body.

9 . The cleaner of claim 8 , wherein the PCB comprises a first PCB and a second PCB, and
wherein one of the first PCB or the second PCB is received in the PCB receiving space.

10 . The cleaner of claim 9 , wherein the first and second connecting bodies are arranged in a second direction, and
wherein the first PCB and the second PCB are arranged in the second direction.

11 . The cleaner of claim 8 , wherein first and second connecting bodies are arranged in a second direction perpendicular to the first direction.

12 . The cleaner of claim 8 , wherein the PCB is inserted in the PCB receiving space downward from an upper side of the PCB receiving space.

13 . The cleaner of claim 1 , wherein the PCB comprises a plurality of pads and a slit, and
wherein the connector comprises a plurality of connecting pins that are configured to contact the plurality of pads and a slit insertion protrusion that is configured to insert into the slit.

14 . The cleaner of claim 1 , wherein when the PCB is coupled to the connector, at least a portion of the connector is received in the handle part.

15 . The cleaner of claim 14 , wherein the handle part comprises a handle, a battery housing and a connection body that connects the handle and the battery housing, and
wherein when the PCB is coupled to the connector, the connection body surrounds the connector.

16 . The cleaner of claim 1 , wherein the suction motor is located above the dust separator in the orientation of the cleaner in which the axis of the cyclonic flow is arranged along a vertical direction.
