A snap-fit ​​bracket 430 is rotatably connected to the side of the mounting housing 100 near the detachable vacuum hose 410, and a brush B431 is fixed to one side of the snap-fit ​​bracket 430. By providing this vacuuming mechanism, when using a handheld vacuum cleaner, the detachable vacuum hose 410 can be... 10 is installed at one end of the handheld vacuum cleaner. The detachable nozzle 420 and brush A421 work together to absorb dust. The dust enters the handheld vacuum cleaner through the detachable suction tube 410. This is the extended suction mode of the handheld vacuum cleaner. Remove the detachable suction tube 410 and move the clip 430 to a horizontal position. The clip 430 and brush B431 absorb dust. This is the standard suction mode of the handheld vacuum cleaner. The dual-mode suction structure can adapt to different suction needs of the handheld vacuum cleaner and improve its applicability.

[0037] Specifically, the top of the dust collection box 520 is provided with a connection port 521, and the discharge port A511 is connected to the connection port 521.

A buckle 540 is provided on the outer side of the mounting frame 530. A dust discharge baffle 550 is rotatably connected to one side of the mounting frame 530 through a shaft pin.

[0038] Specifically, the suction mechanism includes an air inlet 710, which is disposed inside the mounting housing 100. An air intake channel 720 is provided on one side of the air inlet 710, and a suction fan A730 is provided on one side of the air intake channel 720. The suction fan A730 is fixedly connected to the mounting housing 100 by bolts, and a filter screen plate 740 is fixed on one side of the suction fan A730. By providing the suction mechanism, during the dust collection operation, the suction fan A730 is started, and the suction fan A730 performs a suction operation through the air intake channel 720 and the air inlet 710, thereby generating suction at the port of the dust collection mechanism, which allows dust and debris to enter the interior of the first dust collection mechanism, thus realizing the dust collection operation.

[0039] Working principle: In use, the detachable power supply 320 is installed inside the battery compartment 310 and locked in place by the locking buckle assembly 330.

When using the handheld vacuum cleaner, hold the handle 220 and control the start and stop of the handheld vacuum cleaner using the control button 230. The operating data of the handheld vacuum cleaner is displayed on the display screen 240. When using the handheld vacuum cleaner, the detachable suction tube 410 is installed at one end of the handheld vacuum cleaner. The detachable nozzle 420 and brush A421 work together to absorb dust, which enters the handheld vacuum cleaner through the detachable suction tube 410. This is the extended suction mode of the handheld vacuum cleaner. The detachable suction tube 410 is removed, and the latch 430 is moved to a horizontal position. The latch 430 and brush B431 then absorb dust, which is the standard suction mode of the handheld vacuum cleaner. The suction fan A730 is activated, and it operates through the suction channel 720 and suction port 710 to draw air, thereby extending the suction mechanism. The suction generated at the inlet allows dust and debris to enter the first dust collection mechanism. Dust enters the feed pipe 510 and then flows into the dust collection box 520 through the discharge port A511 and the connection port 521. The airflow first passes through the first guide housing 610, where the spiral guide plate 611 on its outer side guides the airflow in a spiral manner, causing the dust-laden air to circulate around the first guide housing 610. The airflow then undergoes the first stage of filtration through the filter cover 630 before entering the second guide housing 620. The air enters the second guide housing 620 through multiple lateral air inlets 621 on the second guide housing 620. The opening direction of the lateral air inlets 621 is tangent to the second guide housing 620, which can perform a second guiding operation on the airflow. The airflow rotates and flows inside the second guide housing 620 and flows around the HEPA assembly 670. The HEPA assembly 670 performs a second stage of filtration on the air. Finally, the clean air enters the suction mechanism through the exhaust port 662. The above mechanisms work together to achieve the adsorption operation of dust.
