specific Embodiment approach 1

[0032] like figure 1 As shown, an air filter consumable life detection system includes a main controller and a light transmittance acquisition device; the main controller is equipped with a life detection program for judging the life of the air filter consumable according to the light transmittance; the light transmittance The acquisition device includes a microcontroller and a light source emitting board 1 for being installed on one side of the air inlet or outlet side of the air filter consumable 3, and also includes a light source installed on the other side of the air filter consumable 3 relative to the light source emitting board 1 The receiving board 2; the center of the light source emitting board 1 and the center of the light source receiving board 2 are provided with air holes; the light emitting board 1 is also provided with a light emitting unit 11, and the light source receiving board 2 corresponds to the light emitting unit 11 The position is provided with a photo...

specific Embodiment approach 2

[0049] The difference between this specific embodiment and specific embodiment 1 is that there are multiple light-emitting units 11 and photosensitive units 21: n light-emitting units 11 are arranged on the light source emitting board 1, and each light-emitting unit 11 is corresponding to each light-emitting unit 11 on the light source receiving board 2 Each photosensitive unit 21 is provided, so that each photosensitive unit 21 can receive the transmitted light of the corresponding light emitting unit 11 through the air filter consumable 3; the microcontroller simultaneously receives the electrical signals sent by n light emitting units 11 through the parallel interface.

[0050] In this specific embodiment, the light-emitting unit 11 is evenly arranged on the light source emitting board 1 around the air hole; the photosensitive unit 21 is evenly arranged on the light source receiving plate 2 around the air hole; the light-emitting unit 11 is an LED lamp ; The photosensitive u...

specific Embodiment approach 3

[0055] like figure 2 As shown, an air purification device adopts the air filter consumable 3 life detection system in the specific embodiment 1 or 2, and the light source emitting board 1 is installed on the air inlet side or the air outlet side of the air filter consumable 3, and the The light source receiving board 2 is installed on the other side of the air filter consumables 3 relative to the light source emitting board 1; the main controller is the automatic main controller of the air purification equipment; the micro-controller is integrated in the main controller or installed in the light source Receiver board 2.

[0056] The light source receiving board 2 and the light source emitting board 1 can be installed in the air purification equipment by brackets, or can be fixed in the air purification equipment by bolts, and those skilled in the art can also reasonably design the installation method according to the internal structure of the air purification equipment.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a method for detecting the life of air filtering consumables, a system for detecting the life of air filtering consumables, and air purification equipment equipped with the system for detecting the life of air filtering consumables. Background technique [0002] In air purification equipment, conventional consumable life detection technologies include countdown method, filter efficiency calculation dust holding capacity method, and wind pressure collection to determine wind resistance method. [0003] The experimental dust used in the calculation of filtration efficiency dust holding capacity method is a specific dust, which is very different from the floating and sinking in our daily life in terms of composition and size, and the ambient humidity and wind speed can affect the filtration efficiency of the filter. The calculation of dust holding capacity by filtration eff...
