Abstract: The present utility model discloses an air-purifying apparatus. The air-purifying apparatus comprises a filter screen, filter screen type determining component, and filter screen service life determining component. The filter screen is for filtering particles and at least one of specific chemical matters in the air. The filter screen determining component is configured to determine a type of the filter screen. The filter screen service life determining component is configured to determine whether the filter screen needs to be changed according to the determined type of the filter screen and a use condition of the filter screen. With the air-purifying device of the present disclosure, remaining service lives of the filter screens of different types or specifications may be obtained, then a user may be prompted when the filter screen needs to be changed, thereby allowing the user to maintain a good air-purifying effect at any time.

Abstract: The present disclosure relates to a method and a control device (100) for operating an air treatment apparatus (10), the control device (100) comprising an input (102) arranged to receive measured data that is indicative of particle concentration from a sensing unit (130), a baseline processing module (104) arranged to derive particle concentration indicative information from the received measured data, an obtaining module (106) arranged to obtain augmenting information that is indicative of air quality, an air quality index augmenting module (108) arranged to determine an augmented air quality index based on the particle concentration indicative information and the augmenting information, and an operation control module (110) arranged to operate the air treatment apparatus (10) based on the augmented air quality index. The disclosure further relates to a corresponding computer program.

Abstract: The present disclosure relates to an humidification attachment module (66) arranged to be coupled with an air treatment apparatus (10), the module comprising a fluid dispensing unit (88) for a humidification fluid that is supplied by a fluid reservoir (86), a flow inlet (74) for an inlet air flow (120), a first flow path defined between the flow inlet (74) and a first flow outlet (76), a second flow path defined between the flow inlet (74) and a second flow outlet (78), and a flow dividing unit (100), wherein the first flow path bypasses the fluid dispensing unit (88), wherein the second flow path passes through the fluid dispensing unit (88), and wherein the flow dividing unit (100) is operable to divide an overall flow through the humidification module into a first flow path component (122) and a second flow path component (124). The present disclosure further relates to air treatment apparatus (10) and to a method of augmenting an air treatment apparatus (10).

Abstract: The present application relates to an apparatus for purifying and/or humidifying air, and a related method for purifying and/or humidifying air. The apparatus comprises a rotary filter (1), a fan (9, 10) for passing air through the rotary filter (1), and a reservoir (4, 5), and wherein the rotation speed of the rotary filter (1) and the settings of the fan (9, 10) depend on the ambient relative humidity and ambient gas pollutant concentration. The apparatus combines the feature of chemisorption with the use of a rotary filter (1), thereby providing an apparatus which is able to purify air and/or regulate the ambient humidity based on humidity levels and levels of a target gas pollutant in the air. The invention removes the need for a pump for liquid transport, removes the need for frequent and expensive filter changes by the user, and instead only requires the user to periodically refresh the filtration solution in the reservoir (4, 5).

Abstract: The invention relates to an evaporative humidifier including a water reservoir, a wick unit and a fan unit. The wick unit is configured to absorb water from the water reservoir. The fan unit is arranged within a fan housing and configured to force an air flow to flow through the wick unit. The fan housing comprises a top cover unit defining at least one annular air outlet at an outer part adjacent a circumference of the top cover unit. One of the main advantages of this invention is that the evaporative humidifier has an optimal air flow path and can operate in a low noise. The invention also relates to an indoor climate controlling system using such an evaporative humidifier.
