Embodiment Construction

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a dust detection device and a dust collector, and the dust detection device comprises the following parts: an air duct structure which is internally provided with a gas channel; an emitting part that is used for emitting first light into the gas channel; a reflection part that is used for enabling the first light to be reflected at least once in the gas channel and formingsecond light which deviates from the first light and can penetrate through the gas channel; a receiving part that is arranged in a staggered manner with the emitting part, and used for receiving thesecond light; the emitting part and the receiving part are integrated into a whole. Due to the fact that the first light is reflected at least once in the gas channel under the action of the reflection part and forms the second light deviating from the first light, dust can be sensed through the at least two light beams, and the probability of dust missing detection is reduced; as the emitting part and the receiving part are integrated, compared with the prior art, the processing cost is reduced, and the assembly efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of dust detection, in particular to a dust detection device and a vacuum cleaner. Background technique [0002] With the development of the economy and the progress of the society, people are increasingly pursuing the quality of life, and the cleanliness of the environment, as an important indicator for evaluating the quality of life, has attracted increasing attention. In order to improve the cleanliness of the environment, vacuum cleaners came into being. [0003] In the vacuum cleaner, the dust detection device is used to determine the dust content after dust suction and filtration, so as to judge the dust collection effect of the vacuum cleaner. The dust detection device has a transmitter and a receiver. The transmitter and the receiver are separated and assembled on both sides of the air duct structure. The light emitted by the transmitter is directly transmitted to the receiver. At this time, the dust...
