Embodiment 1

[0073] This embodiment provides a hand-held vacuum cleaner, such as figure 1 - image 3 As shown, it includes: a main body casing a; an airflow generator, which is arranged in the main body casing a, and the airflow generator is used to form a negative pressure in the main body casing a, and the airflow generator and the main casing A channel for air flow is formed between the bodies a; a dust separator is arranged in the main body casing a, and the dust separator is located between the airflow generator and the main body casing a, and the dust separator Set around the air flow generator. When the dust separator surrounds the airflow generator, the height of the airflow generator and the height of the dust separator partially overlap, so the total height of the dust separator and the airflow generator after assembly is smaller than that of the dust separator and the airflow generator sum of heights. Compared with the separate airflow generator and dust separator in the prio...

Abstract

The invention provides a motor cover and a handheld dust collector. The motor cover comprises a motor housing, wherein an installation cavity suitable for being embedded into an airflow generator is formed in the motor housing; a motor air combing opening, which is formed in the top of the motor housing; an assembly opening, which is formed in the bottom of the motor housing; and a motor air outlet, which is formed in the side part of the motor housing. When the airflow generator is embedded into the motor housing, external airflow is sucked in through the motor air combing opening, and then the airflow is exhausted to the outside through the motor air outlet. The motion path of the airflow in the motor housing is that the airflow enters from the motor air combing opening in the top of the motor housing and then flows towards the bottom of the motor housing, and when the airflow moves to the motor air outlet, the motion direction of the airflow is changed and the airflow is exhausted outwards from the motor air outlet. The airflow moves along the motion path of a fold line, so that noise reflection is facilitated, part of noise is offset, and the noise reduction effect is achieved.

Description

technical field [0001] The invention relates to the technical field of dust and dirt separation devices, in particular to a motor cover and a hand-held vacuum cleaner. Background technique [0002] Vacuum cleaners are commonly used household cleaning appliances. With the development of technology, vacuum cleaners have evolved from traditional large devices to smaller devices that can be held by users. [0003] The working principle of the vacuum cleaner is that there is an airflow generator inside the vacuum cleaner, and the airflow generator forms a lower air pressure inside the vacuum cleaner than at the suction port, so that the suction port of the vacuum cleaner has suction, so that dust and air flow are sucked into the vacuum cleaner together , There is a dust separation filter inside the vacuum cleaner, which filters the dust mixed in the airflow and retransmits the clean air to the external environment. [0004] Since the main core components in the vacuum cleaner eq...
