This included angle is an acute angle from a certain perspective, i.e., the handle of the cleaning device is inclined relative to the display screen assembly, and when the handle of the handheld cleaning device is used for dust collection, the display screen assembly is directly facing the user's perspective.

Further, the rear case 61 is provided with a gas hole through which the gas flowing in the cleaning device flows.

The utility model arranges the display screen 62 on the end shell of the cleaning device, and the display screen component is positioned in the direction deviating from the air inlet pipeline 31 of the cleaning device, so that the user can see the information on the display screen 62 during dust collection; when the shell is disassembled, the display screen 62 is positioned on the rear shell 61, so that the display screen is not easy to damage, and the filtering hypa 63 is positioned on the rear shell 61, and the filtering hypa can be replaced after the shell is disassembled.

Correspondingly, the utility model also provides a cleaning device, including above-mentioned display screen subassembly. Still include main part 10, main part 10 installs the inlet duct 31 that introduces outside dust gas, pastes dust cup 20 and the jettison device that leans on inlet duct 31 motion, filters the gaseous filtration and the separator assembly of dust, motor 13 of filtration dust, and inlet duct 31 and motor 13 are located the both ends of main part 10, and the display screen subassembly can be dismantled the suit and be in motor 13.

A handle device is provided below the main body 10. The filtering and separating assembly for filtering dust and gas includes a filter 30 and a cyclone 12, the cyclone 12 and the motor 13 being of conventional construction. An air inlet duct 31 for introducing external dust and air is installed in the main body 10 before the cyclone 12. Outside dust air is introduced into the filter 30 from the air inlet pipe 31, the air filtered by the filter 30 enters the cyclone separation device 12 for separation, and the motor 13 provides power for filtering and separating.

In this embodiment, the cleaning device further comprises a rotary duct 32 communicating with the air intake duct 31; the interior of the rotary pipe 32 is helical. The air intake duct 31 guides the dust air to the rotary duct 32, and the dust air passing through the rotary duct 32 is rotated to enter the outer circumference of the filter 30. The dirt cup 20, the air inlet duct 31, the rotary duct 32 and the filter 30 are coaxial. The air inlet duct 31 and the rotary duct 32 are integrally mounted on the main body 10, and the filter 30 is fitted over the rotary duct 32. A hollow interlayer is formed between the air inlet pipeline 31 and the filter 30 or between the rotary pipeline 32 and the filter 30, and the interlayer is communicated with a channel for sucking airflow by the motor; the filter 30 is provided with filter holes through which the sucked air is primarily filtered to filter large particles of impurities.

External dust air is introduced into the filter from the air inlet duct 31, and the dirt cup 20 moves against the air inlet duct 31; one end of the ejection device is arranged on the main body part 10, the other end of the ejection device is abutted against the dust cup 20, the ejection device is provided with a dust scraping part 53, and the dust scraping part 53 is abutted against the filter 30; the ejector is moved to push the abutting dirt cup 20 into motion while the dust scraper 53 scrapes the filter 30.

The ejector includes an elastic member and a ring member 50. The ring member 50 interferes with the dirt cup 20 and under the ejection action of the resilient member, the ring member 50 moves and urges the abutting dirt cup 20 to move. The dust scraping part 53 is positioned on the annular part 50, and the elastic part can eject the dust cup 20 and the dust scraping part 53 can scrape dust automatically. The dust scraping part 53 moves toward the dust collecting area 200 to introduce the dust scraped by the filter 30 into the dust collecting area 200 of the dust cup 20.
