Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a small vacuum cleaner. Background Technology

[0002] With the increasing popularity of compact living spaces (such as small urban apartments and studios), refined cleaning needs (such as dust in crevices, debris in vehicles, and dust on office desks), and portable usage scenarios (such as pet hair removal and outdoor equipment cleaning), small vacuum cleaners have become core cleaning devices in homes, cars, and offices due to their advantages of small size, convenient operation, and flexible storage. Existing small vacuum cleaners are mainly divided into three categories: corded handheld, wireless charging, and car-specific. Their core structure usually includes a motor, dust cup, filtration system, nozzle, and handle assembly. The working principle is that the high-speed rotation of the motor generates negative pressure, which draws dust into the dust cup and separates it through the filtration system.

[0003] To enhance functionality, existing small vacuum cleaners typically include a side light; however, this arrangement increases the size of the vacuum cleaner. Utility Model Content

[0004] The purpose of this invention is to provide a small vacuum cleaner to solve the problem that existing small vacuum cleaners with lights cause an increase in the size of the small vacuum cleaner.

[0005] This utility model provides a small vacuum cleaner, including an outer shell, a main shell disposed inside the outer shell, a motor disposed inside the main shell, a dust cup connected to the air inlet end of the motor, a dust cup cover connected to the dust cup, and a battery connected to the main shell. The main shell has an annular rear cover at one end away from the dust cup, a rear air outlet cover in the middle of the annular rear cover, and a mounting groove on the outer side of the annular rear cover. An annular light is disposed in the mounting groove.

[0006] The aforementioned small vacuum cleaner achieves increased lighting functionality without increasing its size by installing a ring-shaped light on the ring-shaped rear cover and using a mounting slot for embedded installation.

[0007] Furthermore, the ring light includes an aluminum substrate and a ring lamp tube disposed on the aluminum substrate.

[0008] Furthermore, two snap-fit ​​blocks are provided at intervals on the outer side of the aluminum substrate. The snap-fit ​​blocks are snap-fit ​​connected to the annular back cover. The annular back cover has snap-fit ​​grooves at positions corresponding to the snap-fit ​​blocks.

[0009] Furthermore, the side circumference of the annular rear cover is provided with multiple anti-slip grooves.

[0010] Furthermore, the dust cup cover includes a cover body and a transition protrusion located at the end of the cover body.

[0011] Furthermore, the annular rear cover is provided with multiple insertion tubes at positions corresponding to the main shell, and the main shell is provided with insertion posts at positions corresponding to the multiple insertion tubes.

[0012] Furthermore, the annular rear cover has multiple first heat dissipation holes on its side.

[0013] Furthermore, the inner side of the annular rear cover is provided with multiple second heat dissipation holes.

[0014] Furthermore, the ring light is connected to the battery via a push-button switch. Attached Figure Description
