Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
The utility model relates to a desktop type air purifier, including the casing 10 that has wind channel 11, along filter medium 20, centrifugal turbine 30 and the drainage flabellum 40 that the air intake to the air outlet direction in wind channel 11 set gradually to and be used for driving centrifugal turbine 30's drive arrangement 50.
The inclination angle alpha of the wall surface of the lower air duct of the air duct 11 is 2-4 degrees, and the outer diameter R of the negative pressure port195-105mm, air flow buffer space L1Is 14-20 mm; the diversion angle beta of the centrifugal turbine 30 is 40-45 degrees and the diversion normal stroke L220-28mm, and the minimum outer diameter R of the turbine2125-129mm, and the maximum outer diameter R of the turbine3Is 134 and 139 mm.
Referring to fig. 1-5, a specific embodiment of the present invention is shown.
As shown in FIG. 3, the aboveAir flow buffer spacing L1The distance between the air suction opening and the filter material surface is; referring to FIG. 5, the diversion normal travel L2The axial depth of the bottom surface cover of the wind wheel.
The driving device 50 is a shaded pole motor.
The utility model discloses still including body 12 and the wind channel body 13 down on the wind channel of setting in casing 10, body 12 is connected from top to bottom with body 13 under the wind channel in order to form wind channel 11 on the wind channel.
The utility model discloses a theory of operation does: the turbine is a power mechanism generating negative pressure, the turbine structure is a main influence factor of power efficiency, and the air duct 11 structure is a main influence factor of transmission efficiency. Wherein, the wall surface inclination angle alpha of the lower wind channel is an important factor for converting the pressure energy generated by the wind wheel into kinetic energy and reducing the pressure energy loss, and the outer diameter R of the negative pressure port1Is an important factor influencing the resistance of the air duct 11, and the external diameter R of the negative pressure port1The smaller the resistance and the smaller the air quantity, the air flow buffer space L1Is an important factor affecting the efficiency of utilization of the filter media 20, and ideally, the air flow buffer space L1The greater the value, the more efficient the utilization of the filter media 20, but the air flow buffer spacing L1The larger the wall resistance, the more the wall resistance increases, so that a moderate value is required; diversion angle beta and diversion normal direction travel L2The pressure energy is an important parameter for converting the pressure energy into kinetic energy, the pressure energy is insufficient when the parameter is too large, a larger load cannot be driven, and the air volume is insufficient when the parameter is too small.
According to the above technical scheme, the utility model discloses centrifugal turbine 30 and the 11 structures in wind channel according to specific parameter design can promote air purifier's performance on little volume's basis, make air purifier have small and exquisite outward appearance concurrently under the prerequisite that possesses big amount of wind, can regard as desktop type air purifier to use, satisfy the demand of single use.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
