Description
Technical field
The utility model relates to air purifier, especially a kind of vehicular air purifier showing PM2.5 numerical value.
Background technology
Worse and worse, the air especially in car is subject to the dual pincer attack of open-air and in-vehicle exposure to air quality in current atmospheric environment, and in car, air is badly in need of being purified.Vehicular air purifier on market does not have the numerical value of clean-up effect to show, and makes user quantitatively cannot know the current value of air PM2.5 and the numerical value after purifying, thus clearly cannot know the effect of air purifier.
Utility model content
The purpose of this utility model is the numerical value after a kind of current value that user can be allowed intuitively to see air PM2.5 and purification provided for the deficiencies in the prior art, thus clearly knows the clean-up effect of in-car air quality and vehicular air purifier.
The purpose of this utility model is achieved through the following technical solutions: a kind of vehicular air purifier showing PM2.5 numerical value, it comprises housing, filter core group, PM2.5 dust sensor, control circuit board, display circuit board, status lamp circuit board, fan and switch, and described filter core group is arranged on top in housing and both sides; PM2.5 dust sensor is connected on control circuit board by wire harness; Control circuit board is fixed on the rear in housing; Display circuit board is connected on control circuit board and the side be arranged in housing by wire harness; Status lamp circuit board is connected on control circuit board by wire harness, is arranged on the top in housing; Fan is fixed on the central authorities in housing; Switch to be connected on control circuit board by wire harness and to be arranged on the opposite side of housing.
Described housing is plastic material.
Described filter core group comprises the filter screen of filtering particle and the active carbon filter core of absorption smell.
Described status lamp circuit board is provided with LED state lamp that is green, yellow, red color.
Compared with prior art, the utility model has the following advantages:
(1), clearly know the air quality in current vehicle.
(2), clearly know the clean-up effect of vehicular air purifier.
(3), by the size of PM2.5 numerical value, the air quantity of adjustment vehicular air purifier automatically, thus reduce the operation of human pilot, reduce driving safety hidden danger.
(4), by air PM2.5 detector and vehicular air purifier be combined on a machine, effectively reduce the area occupied in car.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model control circui schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
Consult Fig. 1, the utility model comprises status lamp circuit board 1, shell of air purifier 2, filter core group 3, display circuit board 4, switch 5, control circuit board 6, PM2.5 dust sensor 7 and fan 8.Described filter core group 3 is arranged on top in shell of air purifier and both sides; PM2.5 dust sensor 7 is connected on control circuit board 6 by wire harness; Control circuit board 6 is fixed on the rear in housing 2; Display circuit board 4 is connected on control circuit board 6 by wire harness, is arranged on the side in housing 2; Status lamp circuit board 1 is connected on control circuit board 6 by wire harness, is arranged on the top in housing 2; Fan 8 is connected on control circuit board 6 by wire harness, is fixed on the central authorities in housing 2; Switch 5 is connected on control circuit board 6 by wire harness, is arranged on the opposite side of housing, namely forms the vehicular air purifier of display PM2.5 numerical value.
The utility model is work like this:
First the utility model is arranged on the position of safety in car, its power supply is connected in the supply hub of automobile 12V, press switch 5, fan 8 will start, air quality simultaneously in PM2.5 dust sensor 7 inspection vehicle, and testing result is transferred on display circuit board 4, by numeral method numerical value by control circuit board 6, testing result is also transferred on status lamp circuit board 1, by LED state lamp Show Color by control circuit board 6 simultaneously.
When numerical value is less than 50, LED state lamp is shown in green, and fan 8 rotating speed is low-grade;
When numerical value is between 50 to 100, LED state lamp is shown as yellow, and fan 8 rotating speed is low-grade;
When numerical value is greater than 100, LED state lamp is shown in red, control circuit board 6 controls fan 8 rotating speed for high-grade simultaneously, to increase the air quantity of air purifier, make the air fast purification in car, until when the testing result of PM2.5 dust sensor 7 is less than 50, control circuit board 6 controls fan 8 adjustment of rotational speed for low-grade, thus clearly know the clean-up effect of vehicular air purifier, and reach the air quantity of adjustment vehicular air purifier automatically, to reduce the operation of human pilot.
