The volume for sterilizing cavity 150 is 3500 cubic centimetres to 5000 cubic centimetres.Preferably, sterilization cavity 150 Volume is about 4000 cubic centimetres, possesses enough sterilizing spaces, plays adequately purification, bactericidal effect to air.
Preferably, in the present embodiment, strainer 140 uses the efficient H13 strainer 140 of photocatalyst, can effectively improve bacterial disease The intercepting efficiency of poison.Relative to middle effect strainer 140 or primary filter screen 140, small particle filter effect is more preferable, bacterial virus Intercepting efficiency is higher, and user's use is felt more relieved, safer.
Fig. 2 is a kind of overall structure diagram for the sterilizing and air-cleaning device 100 that the utility model specific embodiment provides, Referring to figure 2..
Specifically, shell 110 substantially in a rectangular parallelepiped shape, including front casing 101, rear casing 102, left outside shell 104, right casing 103, upper cover and bottom cover.The quantity of air inlet 120 is two, and two air inlets 120 are set to the opposite left and right sides of shell 110. Also, air inlet 120 is set to side lower.Air outlet 130 is set to the front of shell 110, i.e., on front casing 101, and is located at just The top in face.
Fig. 3 is that the air circulation path structure for the sterilizing and air-cleaning device 100 that the utility model specific embodiment provides shows It is intended to, referring to figure 3..
Air is entered the wind from the two sides of blower 160, it is preferable that blower 160 can be using cross flow fan or axial flow blower etc..Wind Machine 160 rotates, and drives air flowing.Air enter the flow direction of blower 160 relative to air sterilization cavity 150 exporter To having deflected 80 degree to 100 degree.That is, air enters back into the two of blower 160 after about 90 degree of turning after sterilizing cavity 150 out End, under the rotation of blower 160, air is discharged from the air outlet 130 of shell 110, and the air of discharge has been carried out high efficiency filter, A large amount of viruses have been intercepted, and have passed through 151 irradiation-sterilize of ultraviolet light source, have achieved the effect that sufficiently cleaned up, sterilization.
Optionally, wind deflector 131 is equipped at air outlet 130, wind deflector 131 has the function for being swung left and right and teetering Can, air-out direction can be changed, preferably, in the present embodiment, one layer of efficient filter 140 is additionally provided at air outlet 130, used Virus is intercepted in further, plays sterilization, catharsis.
Second embodiment
A kind of sterilizing and air-cleaning device 100 provided in this embodiment, the strainer including shell 110 and in shell 110 140, cavity 150 and blower 160 are sterilized.Strainer 140 for filtering air, is equipped with ultraviolet light source 151 in sterilization cavity 150, Ultraviolet light source 151 is used to sterilize air exposure.
Shell 110 is equipped with air inlet 120 and air outlet 130, and strainer 140 is arranged close to air inlet 120, sterilizes cavity 150 are set between strainer 140 and blower 160, and blower 160 is arranged close to air outlet 130;Air enters from air inlet 120, through filtering Net 140, sterilization cavity 150, blower 160, are discharged from air outlet 130;The axial direction of blower 160 and the length direction one of shell 110 It causes;The air inlet direction of blower 160 is vertical with air-out direction.
Optionally, blower 160 uses cross flow fan, and the axial direction of blower 160 is consistent with the length direction of shell 110, i.e. wind The axis direction of machine 160 is left and right directions, and for blower 160 from air inlet 120 through strainer 140, sterilization cavity 150, airflow direction is equal For vertical direction, from bottom to top.After about 90 degree of the air turning that sterilization cavity 150 comes out, enter blower from the left and right sides 160.In this way, extending circulation path of the air in shell 110, that is, when extending stop of the air in shell 110 Between, so that ultraviolet irradiation time is elongated, bactericidal effect is more preferable.
Fig. 4 is another structural schematic diagram for the sterilizing and air-cleaning device 100 that the utility model specific embodiment provides, and is asked Referring to Fig. 4.
In other alternative embodiments, sterilization cavity 150 can be set multiple, be equipped with purple in each sterilization cavity 150 Outside line fluorescent tube.Optionally, efficient H13 strainer 140 can be set at air inlet 120, and use is vertically arranged, i.e., along shell 110 inner sidewall setting.It is easily understood that then efficient H13 strainer 140 also uses two, one there are two air inlets 120 One efficient H13 strainer 140 is set at air inlet 120.Two strainers 140 are oppositely arranged.In this way, sterilization can be further increased The volume of cavity 150 increases bactericidal effect to expand the irradiation area area of quartz burner.
Unmentioned other parts content, identical as content described in first embodiment in the present embodiment, does not make here It is specific to limit.
Sterilizing and air-cleaning device 100 provided by the utility model, installation process and working principle are as follows:
Shell 110 is substantially in cuboid, including former and later two shells, two shells in left and right, upper cover and bottom cover.Air inlet Mouthfuls 120 are set to the lower part of the left and right side of shell 110, and strainer 140 is arranged close to air inlet 120, for filter, intercept germ, The pollutants such as particle.It is equipped with sterilization cavity 150 in shell 110, sterilizes in cavity 150 and quartz burner is installed, for irradiating Air plays bactericidal effect.Air outlet 130 is arranged in the positive top of shell 110, sets at air outlet 130 in shell 110 There is blower 160, blower 160 is used to sterilize, purified air is discharged from air outlet 130.Wind deflector is equipped at air outlet 130 131, strainer 140 etc., strainer 140 can further purify air, and wind deflector 131 can change the wind of air outlet 130 To.The sterilizing and air-cleaning device 100 sterilizes the volume of cavity 150 by increasing, and enhances bactericidal effect.By increasing ultraviolet The distance between source 151 and strainer 140, and increase the distance between ultraviolet light source 151 and blower 160, when increasing irradiation Between, give full play to bactericidal effect.Secondly, by setting blower 160 the length direction axially along shell 110, make blower 160 from Both ends air inlet, i.e. left and right sides air inlet, extend circulation path of the air in shell 110, and slowed down air detaches the time, Improve germicidal efficiency.
