    Description

    BRIEF DESCRIPTION OF THE FIGURE

    [0027] FIG. 1 is a schematic illustration of a preferred embodiment of the present air purifier.

    DESCRIPTION OF A PREFERRED EMBODIMENT

    [0028] A preferred embodiment of the air purifier is described below, in view of FIG. 1.

    [0029] As can be seen in said FIGURE, the present embodiment of the air purifier (1) comprises: [0030] an axially symmetrical air channel (10) extending inside a housing from an inlet (11) to an outlet (12), the inlet (11) being located at the base of the air purifier (1), [0031] a fan (13) configured to generate an air flow from the inlet (11) to the outlet (12) through the channel (10), [0032] purification means (14) arranged inside the channel (10) and configured to purify the air flow, which include two mechanical filtration blocks (14a, 14b) placed in series and two adsorption filtration blocks (14c, 14d), intercalated between said mechanical filtration blocks (14a, 14b), [0033] main sensing means (15) arranged at the inlet and secondary sensing means (17) arranged at the outlet, configured to measure the quality of the air flow at the corresponding points of the channel (10), [0034] a control circuit (16) in connection with the fan (13) and the main (15) and secondary (17) sensing means, and [0035] communication means (18) in wireless communication with a portable device (18a), which are connected to the control circuit (16) and configured to inform the user about various operating parameters of the air purifier (1).

    [0036] Although not shown in FIG. 1, the present preferred embodiment is characterised in that: [0037] the control circuit (16) has a programming configured to compare the parameters provided by the main sensing means (15) with preset target parameters and, from said comparison, adapt the air flow generated by the fan (13), [0038] each mechanical purification block (14a, 14b) is suitable for purification of a different type of particles, [0039] the adsorption filtration blocks (14c, 14d) include a bed of zeolite granules, each of a different composition, [0040] the fan (13) and the control circuit (15) are configured to generate an air flow that takes at least 0.6 seconds to cross each adsorption filtration block (14c, 14d), and in that [0041] said sensing means (15, 17) are configured to sense various types of particles, while the control circuit (16) is configured to analyse, from the sensed particles, whether any of the corresponding filtration blocks (14a, 14b, 14c, 14d) is not functioning correctly.
