The holding portion 2 is disposed on one side of the side surface 107, the motor device 102 and the battery device 103 are both disposed on the bottom surface 104, and the height of the motor device 102 and the height of the battery device 103 are not more than half of the height of the cavity 1011 in the housing 101.

An air suction opening 108 for connecting an external space and the chamber 1011 is formed in the upper half of one side surface 107 of the housing 101, and the air suction opening 108 is used for connecting the pipeline 3 and continuously supplementing air. In use the conduit 3 is connected to a removable dust bag 1012. In the present embodiment, the duct 3 is connected to the air suction opening 108 by means of a fixed connection (e.g., welding) or an integral molding (e.g., an integral molding of a plastic or metal member). Of course, in other embodiments, the duct 3 may be connected to the air suction opening 108 by other movable connection methods such as adhesion, hinge, screw, plug, etc.

In an optional embodiment of the present invention, the air suction opening 108 may also be disposed in the lower half of the casing 101, which only needs to meet the requirement of air suction to make the dust enter the detachable dust bag 1012.

In an alternative embodiment of the present invention, the housing 101 may also be a standard or non-standard structure other than the present embodiment, and at least has a bottom surface 104 and at least one side surface 107.

With continued reference to fig. 1, the present embodiment provides a dust bag type handheld vacuum cleaner, wherein an opening is formed at the top of the housing 101, the detachable dust bag 1012 can be installed in the chamber 1011 from the opening, and the detachable dust bag 1012 is used for filtering and collecting dust and garbage. An openable and closable lid member 105 is provided at an opening of the housing 101, the lid member 105 exposing the opening of the housing 101 when opened, and the lid member 105 closing the opening of the housing 101 when closed. The cover 105 may be hinged or pivotally connected to the housing 101, or may be mechanically or movably connected to the housing 101 except for the hinged or pivotally connected connection, so long as the opening of the housing 101 is exposed for mounting the removable dust bag 1012.

With continued reference to fig. 1, the duct 3 and the cover 105 are separate components (i.e., they are separate structures), so that the opening/closing of the cover 105 is prevented from affecting the position and posture of the duct 3. The duct 3 has a first opening 301 connected to the suction opening 108 and a second opening 302 for connecting to a detachable dust bag 1012, the cross sections of the first opening 301 and the second opening 302 being non-parallel to each other. When the dust bag type handheld dust collector is placed horizontally on a horizontal plane, the included angle alpha between the cross section of the second opening 302 and the horizontal plane is 0-75 degrees.

Referring to fig. 2, the specific structure of the duct 3 is described below:

the duct 3 has at least a part of a bent pipe from the first opening 301 to the second opening 302, in this embodiment, the duct 3 is bent from the first opening 301 to the second opening 302 along the length of the duct, so that the duct 3 is a bent pipe as a whole, and the dust collecting inlet of the detachable dust bag 1012 and the air suction opening 108 are located at different planes by using the duct 3. The first opening 301 is often angled at a downward slant during use of the cleaner. If the first opening 301 and the second opening 302 are parallel, this means that the second opening is also at a downward angle, which results in dust or light weight trash in the detachable dust bag being easily dumped. By arranging the cross-sections of the two openings non-parallel, it is advantageous to avoid the above-mentioned problems.

When the dust bag type handheld dust collector is placed horizontally, the included angle alpha between the cross section of the second opening 302 and the horizontal plane is 0-75 degrees. Considering that the bottom surface will form an angle with the horizontal surface during normal use, i.e. the first opening 301 is inclined downwards, the angle is usually about 15 °. That is, during the use process, the included angle between the second opening 302 and the horizontal plane at least does not exceed 90 ° too much, and the second opening 302 does not present a state of being easy to dump dust and garbage.
