Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
As shown in fig. 1 to 3, according to an embodiment of the air purification apparatus of the present invention, the air purification apparatus can be used at an air outlet of an air conditioner, a fresh air blower, or an air purifier. The air cleaning device includes a housing 100, an ionizer, and a plurality of air deflectors 400. In the present embodiment, the housing 100 is a strip, and the housing 100 has a strip air inlet and a strip air outlet corresponding to the air inlet.
Disposed within housing 100 is an ionizer that includes one or more sets of ion generating electrode sets 200. The ion generating electrode assembly 200 is powered by a high voltage power supply 300. The ion generating electrode group 200 includes negative ion generating electrodes 210 and positive ion generating electrodes 220 arranged at intervals along the length direction of the air inlet, and the number of the negative ion generating electrodes 210 is greater than that of the positive ion generating electrodes 220. When the ion generating electrode set 200 is provided with a plurality of sets, the plurality of sets of ion generating electrode sets 200 are arranged along the length direction of the air inlet. In the present embodiment, the ion generating electrode group 200 is provided with two groups, and each group of the ion generating electrode group 200 includes two negative ion generating electrodes 210 and one positive ion generating electrode 220.
The high voltage power supply 300 includes two outputs of a positive electrode and a negative electrode, and respectively outputs a positive high voltage and a negative high voltage of a small current. The high voltage power supply 300 input is 12VDC or other low dc power input, and may also be 220VAC or other ac power input. The range of the output positive high voltage is +1kV to +10kV DC, and the range of the output negative high voltage is-1 kV to-10 kV DC. The negative ion generating electrode 210 and the high voltage power supply 300 are electrically connected to the output negative electrode of the high voltage power supply 300 through a wire. The positive ion generating electrode 220 and the high voltage power supply 300 are electrically connected to the output positive electrode of the high voltage power supply 300 through a wire. The high voltage power supply 300 may be designed separately from the housing 100 or may be designed inside the housing 100. In other embodiments, the number of positive ion generators is not greater than the number of negative ion generators, and the number of generated negative ions can be greater than the number of positive ions by adjusting the absolute value of the output voltage of the power supply and the output voltage time.
The air deflectors 400 are disposed at the air outlet and located at two ends of the ion generating electrode assembly 200, respectively, an included angle α is formed between the air deflectors 400 and the direction of the inlet air, as shown in fig. 2, and the air outlets at two ends of the ion generating electrode assembly 200 at the air outlet are converged toward the middle by the air deflectors 400. The air deflectors 400 at the left end and the right end are not parallel to the wind direction and form a certain included angle, so that the direction of the wind flowing through is changed, the negative ions generated by the negative ion emitting electrodes at the left end and the right end are not all blown out in parallel by the wind, and the changed direction is intersected with the positive ions generated by the positive ion emitting electrode in the middle and blown out in parallel, so that the collision of the positive ions and the negative ions is facilitated, and the purification effect is stronger.
The air purification device is simple in structure, and the strip-shaped design enables the air outlet to blow out more ions; the positive and negative ion generating electrodes 210 are sequentially arranged at intervals, so that collision after positive and negative ions are diffused is facilitated, and the purification effect is improved; meanwhile, the number of the negative ion generating electrodes 210 is more than that of the positive ion generating electrodes 220, so that the concentration of negative ions is higher than that of positive ions, and the health is benefited.
In this embodiment, the air purification apparatus further includes a driving component, and the driving component is used for driving the air deflector 400 to rotate, so as to adjust an included angle α between the air deflector 400 and the wind direction of the intake air. Preferably, the drive means comprises a motor and a drive mechanism. The motor drives the air deflector 400 to rotate through the driving mechanism. In other embodiments, the driving member may be a manual driving member, and the wind deflector 400 is manually adjusted to rotate.
By arranging the driving part, the included angle alpha between the air deflector 400 and the air inlet direction can be adjusted according to the wind speed. When the wind speed is increased, the included angle alpha between the wind deflector 400 and the wind direction is reduced; when the wind speed is reduced, the included angle alpha between the wind deflector 400 and the wind direction is increased. When the wind speed is slow, the large included angle α enables the wind blowing out negative ions and the wind blowing out positive ions in parallel meeting the wind deflector 400 to intersect within a certain time. When the wind speed is high, the small included angle alpha enables the wind which meets the wind deflector 400 and blows out negative ions and the wind which blows out positive ions in parallel to intersect within a certain time, and the intersecting position is far away from the wind outlet, so that the collision of the positive ions and the negative ions in a larger indoor space is facilitated.
Further, the positive ion generating electrode 220 is at least one of a metal sharp needle, a carbon brush, or a conductive fiber sharp rod. The negative ion generating electrode 210 is at least one of a metal sharp needle, a carbon brush, or a conductive fiber sharp rod. Preferably, the outer diameter distance d between the negative ion-generating electrode 210 and the positive ion-generating electrode 220 is > 10 mm.
In this embodiment, the housing 100 includes a base 110 and a top cover 120 fixed on the base 110, the ion generating electrode assembly 200 is fixed on the base 110, and the top cover 120 has a grid forming an air inlet and an air outlet. In this embodiment, the top of the top cover 120 is provided with an air inlet, and the front side is provided with an air outlet. The top cover 120 serves to protect the positive ion generating electrode 220 and the negative ion generating electrode 210 from being damaged by collision, and also to prevent the metal needle tip of the ionizer from stabbing a human body. The design of grid can guarantee that wind flows through, reduces the windage, guarantees simultaneously that the ion is taken out by wind and is diffused to the indoor space. The base 110 and the top cover 120 are fixedly connected through a buckle, a screw, or other methods, and according to a specific design, the base 110 and the top cover 120 may be designed as an integral structure.
The air purification device can be used for air conditioners, fresh air blowers or air purifier air outlets.

s100, acquiring the wind speed of the current air purification device;
s200, adjusting an included angle alpha between the air deflector and the wind direction according to the wind speed;
s210, when the wind speed is increased, reducing an included angle alpha between the air deflector and the wind direction;
s220, when the wind speed is reduced, the included angle alpha between the wind deflector and the wind direction is increased.
The included angle alpha between the air deflector and the wind direction has a minimum preset value alpha 1 and a maximum preset value alpha 2.
In step S210, the wind speed of the air purification apparatus gradually increases until the included angle α between the wind deflector and the wind direction is adjusted to the minimum preset value α 1. When the wind speed is high, the small included angle alpha 1 enables the wind which meets the air deflector and blows out negative ions and the wind which blows out positive ions in parallel to intersect within a certain time, and the intersecting position is far away from the air outlet, so that the collision of the positive ions and the negative ions in a larger indoor space is facilitated.
In step S220, when the wind speed of the air purifying device is the lowest wind speed, the included angle α between the wind deflector and the wind direction is the maximum preset value α 2. When the wind speed is slow, the larger included angle alpha 2 can ensure that the wind which meets the wind deflector and blows out negative ions and the wind which blows out positive ions in parallel can be converged within a certain time.
In this embodiment, the air deflector is arranged inside the housing of the air purification device, and in other embodiments, the air deflector can also be designed outside the air purification device, the intersection of positive and negative ions is enhanced in a structural air deflecting manner, and the angle of the air deflector is adjusted according to different wind speeds, so that the intersection distance between the negative ion wind and the positive ion wind within a certain time is further.
Further, the air purification device is also provided with a powerful purification mode, in the powerful purification mode, the air speed of the air purification device is maximum, the output voltage of the high-voltage power supply is output at a second preset voltage value, the second preset voltage value is larger than the voltage value in normal use, and the air deflector is swung to a preset angle alpha 3, wherein alpha 3 is not smaller than alpha 2.
