Description

Technical Field

[0001] This utility model relates to the field of household cleaning technology, and in particular to a handheld vacuum cleaner that is easy to clean the dust bag. Background Technology

[0002] Handheld vacuum cleaners typically include two types: handheld dust cup vacuum cleaners and handheld dust bag vacuum cleaners. Handheld dust bag vacuum cleaners usually consist of a main unit and a dust bag located inside the main unit. This type of technology can be referenced in Chinese utility model patent CN209547882U. Since the dust bag is disposable, it avoids the user's actions of emptying and rinsing the dust cup, and is therefore increasingly popular among users. However, when handling this type of dust bag, the user's hands still need to come into contact with the dust bag, which can cause discomfort and the possibility of secondary pollution. Utility Model Content

[0007] It also includes a deflection spring disposed between the deflector and the connecting arm, wherein the deflector includes a pair of elastic covers disposed adjacent to the deflection shaft and housing one end of the deflection spring.

[0008] The mounting base includes a receiving space that accommodates the deflector and the dust bag holder and is defined by the fixed support arm and the connecting arm, and a pair of mounting base side plates that extend opposite each other from the inside of the fixed support arm, wherein the gap between the mounting base side plates and the deflector accommodates the dust bag holder.

[0009] The fixed base and the deflector are at least partially located inside the dust collection chamber.

[0010] The cover is designed to detachably cover the top of the dust collection chamber and includes a cover button at one end and a cover hook at the other end. The cover button has a button protrusion at one end, and the handle has a latching hole that engages with the button protrusion and a latching groove that engages with the cover hook.

[0011] It also includes a vacuum motor located within the handheld part and downstream of the dust bag assembly, and an air inlet duct connected to the dust collection chamber, wherein the deflector is closer to the air inlet duct than the fixed arm.

[0012] The handheld part includes a dust collection chamber at the front end, a dust collection chamber opening with one end connected to the air inlet pipe and the other end connected to the dust collection chamber, a handle at the rear end, and a motor housing part located between the dust collection chamber and the handle for housing the vacuum motor.

[0013] The dust bag holder fixing assembly includes a sealing ring disposed on the deflector, wherein the sealing ring is disposed around the outside of the opening of the deflector.

[0014] The cover is located above the vacuum motor, and the deflection axis of the deflector is located above the central axis of the vacuum motor.

[0015] The beneficial effects of this utility model are: avoiding direct contact between the user and the dust bag, making the dust bag cleaning operation convenient, improving the user experience, and reducing the chance of secondary pollution. Attached Figure Description
