CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a 371 of International Application No. PCT/KR2018/008773 filed on Aug. 2, 2018, which claims priority to Korean Patent Application No. 10-2017-0110942 filed on Aug. 31, 2017, the disclosures of which are herein incorporated by reference in their entirety.

BACKGROUND

1. Field

The present disclosure relates to a vacuum cleaner, and more particularly to a vacuum cleaner capable of enhancing the convenience of use with an improved handle structure.

2. Description of Related Art

In general, a vacuum cleaner is a device capable of performing cleaning by generating a suction force and sucking foreign substances such as dust together with air and then removing the foreign substances using a dust collector and the like provided inside a main body.
The vacuum cleaner is mainly classified into a canister type and an upright type. The canister type cleaner includes a main body in which a blower, a dust collector, and the like are mounted, a suction nozzle installed separately from the main body to suck dust from a floor, and a connection pipe to connect the main body and the suction nozzle.
Therefore, a user performs cleaning while holding a handle installed to the connection pipe and moving the suction nozzle in a direction to be cleaned.
In particular, the user may operate the vacuum cleaner by pulling the handle of a trigger type with a finger. The user turns the vacuum cleaner on or off by grasping a handle grip with the hand and pulling and releasing a trigger provided at a position where an index finger touches.
However, the trigger type vacuum cleaner is inconvenient in that the user needs to keep pulling the trigger throughout the cleaning.
In addition, the trigger type vacuum cleaner is cumbersome in that a button for adjusting the suction intensity of the cleaner is separately provided so that the user needs to adjust the suction intensity by using a hand other than the hand holding the handle, which may be a factor that lowers the cleaning efficiency.

SUMMARY

The present disclosure is directed to providing a vacuum cleaner capable of enhancing the convenience of use by improving the handle structure.
Further, the present disclosure is directed to providing a vacuum cleaner capable of enhancing the operability of a user by separately providing an on/off power button for the operation and using a trigger as a function to change the suction intensity.
One aspect of the present disclosure provides a vacuum cleaner including a cleaner main body disposed along a longitudinal direction of a suction nozzle and configured to generate a suction force, and a handle provided on the cleaner main body and configured to be gripped and manipulated by a user, wherein the handle includes a first button provided to select on or off of the cleaner main body, and a second button provided to selectively adjust the suction force.
The handle may include a handle grip portion and a battery mounting portion provided to be in parallel with the handle grip portion.
The second button may be disposed on the handle grip portion.
The first button may be disposed on the cleaner main body.
The first button may be disposed on an upper surface of the cleaner main body.
The second button may include a trigger.
The cleaner main body may include a dust collector disposed along the longitudinal direction of the suction nozzle and configured to separate foreign substances from the air introduced through the suction nozzle.
The cleaner main body may include a motor configured to generate the suction force, and the first button and the second button may be connected to the motor.
The cleaner main body may include a filter configured to filter the air passing through the dust collector and at least one discharge port configured such that the air that has passed through the filter is discharged.
The second button may be configured to be movable in the longitudinal direction of the suction nozzle.
The second body may include a button guide configured to guide the second button to be moved horizontally.
The vacuum cleaner may further include an elastic member disposed between the second button and the button guide.
Another aspect of the present disclosure provides a vacuum cleaner including a cleaner main body disposed along a longitudinal direction of a suction nozzle and configured to generate a suction force, and a handle provided on the cleaner main body and configured to be gripped and manipulated by a user, wherein the cleaner main body includes a first body provided with a dust collector configured to separate foreign substances from the air introduced through the suction nozzle, a second body connected to the first body and configured such that the handle is provided on at least a portion thereof and a motor to generate the suction force is provided on the other portion thereof, a first button provided on the second body to select on or off of the cleaner main body, and a second button provided on the second body to selectively adjust the suction force.
The handle may include a handle grip portion and a battery mounting portion extending from the second body to be in parallel with the handle grip portion.
The second button may be disposed on the handle grip portion.
The first button may be disposed on an upper surface of the second body.
The motor may be disposed between the first button and the second button.
The second button may include a trigger.
The first button and the second button may be connected to the motor.
The second body may include a filter configured to filter the air passing through the dust collector and at least one discharge port configured such that the air that has passed through the filter is discharged.
