A method of recording the life of consumables

Abstract

The invention relates to the field of consumable life monitoring, and especially relates to a method for recording the life of a consumable. The method for recording the life of the consumable comprises the following steps: A, arranging a photochromic unit on a consumable to be recorded; B, controlling a light emitting unit to emit incident lights adapting to the life consumption condition of theconsumable to be recorded to the photochromic unit; C, using a light receiving unit to receive incident light reflected lights reflected by the photochromic unit; and D, calculating the reflectivity of the photochromic unit according to the incident lights emitted by the light emitting unit and the reflected lights received by the light receiving unit to correspondingly obtain the life of the consumable to be recorded in order to realize the consumable life recording. The method has the advantages of realization of recording the life of the consumable, simple structure, easiness in installation, simplicity in use, low cost, and wide application range.

Description

technical field [0001] The invention belongs to the field of life monitoring of consumables, and in particular relates to a method for recording the life of consumables. Background technique [0002] Consumables, as the name implies, consumables, lost materials, and consumables are broadly defined, and generally refer to accessories that are frequently consumed, such as printer ink cartridges, computer mice, air purifier filters, etc., all belong to consumables. Due to the service life of consumables, it is necessary to record and monitor their service life so that they can be replaced in time so that the equipment can work normally. [0003] At present, the life marking of many consumables on the market adopts the electronic chip method. Although the electronic chip method is more accurate, it is expensive and not easy to fix. It does not require high precision in life measurement and is not suitable for occasions with strict cost control, such as Low-cost air purifier fil...

[0003] At present, the life marking of many consumables on the market adopts the electronic chip method. Although the electronic chip method is more accurate, it is expensive and not easy to fix. It does not require high precision in life measurement and is not suitable for occasions with strict cost control, such as Filter life testing for low-cost air purifiers. Since the frame of the low-cost filter is made of paper or non-woven materials, it is not suitable to implant expensive electronic chips, and it is not easy to fix
