Embodiment 1

[0084] Such as image 3 As shown, the light source 9 is placed on the side wall 15 of the air intake cabin 3 . A light baffle 12 is arranged on the side of the light source 9 passing through the filter core 2 to prevent the light emitted by the light source 9 from leaking from the side and prevent the light emitted by the light source 9 from directly passing through the filter core 2 to exit. The light blocking plate 12 is arranged in a direction perpendicular to the light from the light source, so as to prevent the light emitted by the light source 9 from directly passing through the filter core 2 to exit. The side of the light baffle plate 12 close to the light source 9 has a reflective surface, which is used to reflect and irradiate light into the wind inlet compartment 3 . A reflective surface 14 may be provided on the side facing the filter element 2 in the wind inlet compartment 3 for uniformly reflecting light onto the filter element 2 . A light baffle 13 is arranged ...

Embodiment 2

[0089] Such as Figure 5 As shown, the light source 9 is arranged on the side facing the filter element 2 in the air inlet cabin 3 . The light source 9 is a strip light source. A light baffle 13 can be arranged on the circumference of the wind wheel 11 to prevent the light source from overflowing from the air outlet 5 through the air inlet of the wind wheel, causing light interference and affecting the user's judgment of the brightness of the light source at the air inlet surface (cover plate 1). Such as Figure 6 As shown, the light source 9 is covered with a light source optimizer 16 to ensure that the light emitted through the filter element 2 is more uniform through the refraction and reflection of the light source.

[0090] According to the above measurement method (wherein, the color temperature of the light source is SMT-LED 3.0*3.0 positive white light 6500K, and the illuminance meter is placed at a distance of 1 meter directly below the light source), the curve valu...

Embodiment 3

[0093] Such as Figure 7 As shown, the light source 9 is arranged on the side facing the filter core 2 in the air inlet cabin 3; meanwhile, the light source 9 is also located on the back side of the reflective surface 14, has a certain distance from the reflective surface 14, and faces the direction of the filter core 2. The light passes through the reflective surface 14 towards the direction of the filter core 2, and the reflection effect of the reflective surface 14 ensures that the light transmitted through the filter core 2 is uniform. The light source 9 is covered with a light source optimizer 16, which ensures that the light transmitted through the filter core 2 is more uniform through the refraction and reflection of the light source. A light baffle 13 can be arranged on the circumference of the wind wheel 11 to prevent the light source from overflowing from the air outlet 5 through the air inlet of the wind wheel, causing light interference and affecting the user's jud...

Abstract

The invention discloses a method for monitoring the service life of a filter element. The method comprises the steps that a light source (9) is arranged in an air inlet cabin (3) located between the filter element (2) of an air purifier and a wind wheel assembly (4); and monitoring the service life of the filter element of the air purifier through the brightness of the light source (9) emitted through the filter element (2). According to the invention, a user can directly monitor the service life of the filter element in real time through visual impression, and the method is visual, simple and suitable for various user groups. Meanwhile, the illumination brightness can be provided for use places (such as carriages of rail traffic tools).

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a method for monitoring the service life of an air purifier filter element. [0002] technical background [0003] In order to improve air quality, most family houses use air purification equipment. Air purification equipment can effectively remove indoor gas pollutants and particulate matter to protect human health. [0004] There are many air purification equipment on the market. For consumers, in addition to the amount of clean air, power, noise, and service life are also important evaluation parameters for choosing air purification equipment. The purification life of air purification equipment usually refers to the total operating time when the indoor pollutants are removed and the clean air volume value is reduced to half of the initial value. Air purification equipment will affect its performance due to dust accumulation. When the filter element of the air purific...
