Abstract

A provided air purifier comprises a purifier shell, an air inlet channel arranged in the purifier shell and a dust sensor used for detecting air quality, wherein the purifier shell is provided with an air inlet hole, the dust sensor is provided with a detection hole, one end of the detection hole is communicated with the air inlet hole, and the other end of the detection hole is communicated with the air inlet channel. When the air purifier works, a blower fan rotates, air starts to enter the air inlet channel, a negative-pressure air flow is formed in the air inlet channel, and due to the facts that the air inlet hole is communicated with the detection hole and the detection hole is communicated with the air inlet channel, air at the outer side of the purifier shell enters the purifier shell through the air inlet hole and enters the air inlet channel via the detection hole. Because existence of the negative pressure is capable of improving the air flowing speed and also is capable of guaranteeing the volume of the external air entering the dust sensor, the detection accuracy of the dust sensor is improved, the air purifier is prevented from generating automatic purifying misoperation or delayed motion, and the automation performance of the air purifier is improved.

Description

A kind of air purifier
Technical field
The present invention relates to air-treatment technical field, particularly a kind of air purifier.
Background technology
Along with social economy's persistent levels advances, the demand of people to quality of life improves day by day, more and more pays close attention to the living environment residing for self.Recent years, the air pollution episode constantly occurred has promoted the public greatly to the demand of air purifier and understanding, and the development of air purifier is also more and more rapider.
In order to realize the detection to dust, partial air clarifier is provided with dust sensor, is detected the amount of fine solid particle thing in air, set different operational mode with reminding user to air purifier by dust sensor.But dust sensor of the prior art is arranged in the internal closed space of air purifier usually, by the content of impurity in the flow detection air of air.When air flow amount is less, the air capacity that dust sensor is difficult to touch air or detection is less, thus the accuracy that impact detects, the self-clearing misoperation of air purifier or delay voltage may be caused, namely affect the use of air purifier.
Therefore, how improving the accuracy that dust sensor detects, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The object of this invention is to provide a kind of dust sensor, to improve the accuracy that dust sensor detects.
For solving the problems of the technologies described above, the invention provides following technical scheme:
A kind of air purifier, comprising clarifier shell, being arranged on the air intake passage of described clarifier enclosure and the dust sensor for detecting air quality, wherein, described clarifier shell offers fresh air inlet, described dust sensor offers detect aperture, and described detect aperture one end is communicated with described fresh air inlet, and the other end of described detect aperture is communicated with described air intake passage.
Preferably, in above-mentioned air purifier, described dust sensor is arranged on described clarifier shell by tube connector, and the Single port of described tube connector is relative with described fresh air inlet, and another port is relative with described detect aperture.
Preferably, in above-mentioned air purifier, described fresh air inlet is multiple, and all positioned opposite with the port of described tube connector.
Preferably, in above-mentioned air purifier, also comprise the connection fin on the outer wall being arranged on described tube connector.
Preferably, in above-mentioned air purifier, also comprise the installing rack for fixing described dust sensor.
Preferably, in above-mentioned air purifier, described installing rack comprises:
Be arranged on the connecting plate on the outer wall of described air intake passage;
Be connected with described connecting plate for the installing plate of fixing described dust sensor.
Preferably, in above-mentioned air purifier, described connecting plate and described air intake passage are integral type structure.
Preferably, in above-mentioned air purifier, described detect aperture is communicated with described air intake passage by the ventilating opening be opened on described air intake passage sidewall.
Preferably, in above-mentioned air purifier, described detect aperture and described air intake passage pass through the gap area between the side wall ends of air intake passage and described clarifier shell.
The invention provides a kind of air purifier, comprising clarifier shell, being arranged on the air intake passage of clarifier enclosure and the dust sensor for detecting air quality, wherein, this clarifier shell offers fresh air inlet, dust sensor offers detect aperture, and detect aperture one end is communicated with fresh air inlet, the other end is communicated with air intake passage.By above-mentioned setting, when air purifier works, the blower fan of air purifier rotates, and air intake passage starts air intake, therefore, there is pressure differential in air intake passage and clarifier outer side, namely forms air-negative-pressure in air intake passage, because the fresh air inlet on clarifier shell is communicated with the detect aperture on dust sensor, and detect aperture is communicated with air intake passage, therefore, the air of clarifier outer side enters clarifier shell by fresh air inlet, and enters air intake passage through detect aperture.Existence due to negative pressure can improve the speed of outside air flowing, also can ensure that outside air enters the flow of dust sensor simultaneously, therefore, effectively improve the accuracy that dust sensor detects, prevent air purifier from occurring self-clearing misoperation or delay voltage, improve the automation performance of air purifier.
