Dust display

Abstract

The invention discloses a dust display which comprises a display cavity, wherein the display cavity is communicated with an air inlet pipe and an air outlet pipe and is made of a transparent material; and in addition, the display cavity comprises a cylindrical shell and an internal cavity fixedly connected with the shell, an inflow part and a conical flow guide part are formed at two ends of the internal cavity, and an opening structure is arranged at the end part of the conical flow guide part. The dust display also comprises a cup shield which is detachably and fixedly connected to the end part of the display cavity and accommodates the conical flow guide part. The dust display provided by the invention is provided with an independent internal cavity structure and is capable of effectively improving the rotating force and effectively separating dust from air flow; simultaneously the inlet pipe of the dust display is directly connected with the internal cavity, thereby achieving a more sensitive display effect that a very small amount of dust also can be displayed; and an outer square hole at the end part of the cup shield is communicated with the outside, so that dust at corners can be cleared up very well and no dust can be left.

Description

technical field [0001] The invention relates to a vacuum cleaner; in particular, it relates to a dust display for the suction head of the vacuum cleaner. Background technique [0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room. [0003] Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum cleaner, forming an instantaneous vacuum...

Problems solved by technology

[0010] But the dust monitor of existing structure, can't discharge by oneself after dust enters, and in the process of vacuuming, the actual effect of dust is not good, and the button 112 that will often bend over and press air valve 111 is extremely inconvenient; And when button 112 is pressed , will still form a dead zone of air flow at the angle 128 between the cone-shaped flow guide shell and the outer cover 12, where a large amount of dust will remain, and the dust adhering to the inside of the transparent display cannot be removed, and the display effect will become worse and worse, so it is necessary to Wash separately, inconvenient to use
