One end of the second elastic element 1132 abuts against the body 11, and the other end abuts against the unlocking button 1133. When the unlock button 1133 is pressed, the second locking buckle 1131 slides along the third direction CC, and the second elastic element 1132 is elastically deformed. When the unlock button 1133 is released, the second elastic element 1132 is reset, so as to push the second latch 1131 and the unlock button 1133 to reset. In this embodiment, one end of the second elastic element 1132 abuts against the body 11, and the other end abuts against the unlocking button 1133, but it is understood that in other embodiments, the second elastic element 1132 may also be configured to have one end abutting against the body 11, and the other end abutting against the second latch 1131. Referring to fig. 4, the bouncing mechanism 114 is fixedly installed on the bottom wall of the accommodating groove 111 for cooperating with the suction force generating unit 30. The pop-up mechanism 114 includes a pin 1141 and a first elastic element 1142 cooperating with the pin 1141.

Referring to fig. 3, fig. 1 and fig. 2, the handle 12 is formed by extending outward from the bottom of the accommodating groove 111 along the second direction BB. An included angle alpha is formed between the handle 12 and the machine body 11. The included angle alpha is between 80 and 140 degrees. Preferably, the included angle α is 110 degrees. The handle 12 has a height H in a direction perpendicular to the first direction AA. The height H is between 85mm and 110 mm. The handle 12 is further provided with a switch button 121 and a boss 122. The switch button 121 is used to control the handheld vacuum cleaner 100 to work. The protrusion 122 is located on a side of the switch button 121 away from the body 11, so that a user can apply a lifting force through the protrusion 122 when holding the handle 12, and also can protect the switch button 121. Preferably, the boss 122 is circular arc-shaped. The base 13 is located on a side of the handle 12 away from the body 11, and is provided with a docking interface (not shown). The docking interface is configured to dock with the battery pack 50, thereby obtaining power of the battery pack 50.

Referring to fig. 6, as well as fig. 1 and 2, the dust collecting unit 20 is fixedly installed on the suction force generating unit 30 to cooperate with the air inlet duct 112 to collect dust, dirt, and the like. The dust collection unit 20 includes a dirt cup 21 and a filter assembly 22. In the present embodiment, the dust cup 21 has a cylindrical shape. The axis of the dirt cup 21 is parallel to the first direction AA. A first latch 211 is disposed on a side of the dirt cup 21 facing the receiving groove 111 and engaged with the second latch 1131, so that the dirt collecting unit 20 is fixed in the receiving groove 111 by the engagement of the first latch 211 and the second latch 1131. The filter assembly 22 includes a first filter assembly 221 and a second filter assembly 222. The first filter assembly 221 is positioned within the dirt cup 21 to separate debris, dirt particles, etc. from the dirty air such that the debris, dirt particles, etc. remain within the dirt cup 21. In this embodiment, the first filter assembly 221 is substantially cylindrical, and includes a metal filter 2211 in a ring shape and a filter element member disposed in the metal filter 2211. The second filter assembly 222 is disposed at an end of the dust collecting unit 20 away from the first air inlet 1121, that is: the dust cup 21 is located at an end away from the first air inlet 1121 and connected to the suction force generating unit 30. Preferably, a filter element is arranged in the second filter assembly 23.

In the embodiment, the first pivoting member 301 is a pivot, but it is understood that in other embodiments, the first pivoting member 301 may be a shaft hole. The suction force generating unit 30 includes a housing 31, a motor (not shown) disposed in the housing 31, an impeller (not shown) mounted on the motor, and an air outlet 32. The housing 31 is provided with a receiving cavity 311 and a display screen 312. The accommodating cavity 311 is used for accommodating the motor and the impeller. The display screen 312 is used for displaying the operation information of the hand-held cleaner 100. The working information can be electric quantity information, charging state information, dust fullness early warning information, blockage information and the like. Preferably, the display screen 311 is perpendicular to the axis of the motor. The axis of the motor is parallel to the first direction AA. The air outlet part 32 is disposed at one end of the housing 31 far away from the display screen 312, and is connected and matched with the dust collecting unit 20. The air outlet portion 32 includes an air outlet 321 disposed at one end of the casing 31 far away from the display screen 312 and an air outlet filter 322 located in the casing 31 and corresponding to the air outlet 321. The air outlet direction of the air outlet 321 is perpendicular to the first direction AA. The outlet filter assembly 322 is used to further filter the airflow before it exits the hand-held cleaner 100. Preferably, referring to fig. 8, the outlet air filter assembly 322 is provided with a handle 3221, so that a user can conveniently take out and replace the outlet air filter assembly 322.
