Detailed Description

To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1, a discharge device includes: the device comprises a fixed support 10, a discharge cavity 11 with an air inlet and an air outlet is formed by the construction of the fixed support 10; the discharge electrode 20, the discharge electrode 20 is fixedly arranged in the discharge cavity 11; the wind shield 30 is provided with a vent hole, and the wind shield 30 is arranged in the discharge cavity 11 and used for shielding air entering from the air inlet.

Specifically, the fixing bracket 10 is a frame for fixing the discharge electrode 20 and the wind shield 30, and the discharge electrode 20 is a discharge device for removing harmful substances such as formaldehyde and dust in the air by discharging in a glow discharge manner or a plasma discharge manner, thereby purifying the air. After the fixed support 10 is built to form the discharge cavity 11 with the air inlet and the air outlet, air flows into the discharge cavity 11 from the air inlet under the action of a fan and the like, the discharge electrode 20 in the discharge cavity 11 performs air purification operation, and finally purified air flows out through the air outlet. When being provided with the deep bead 30 in the cavity that discharges 11, no matter the deep bead 30 sets up between air intake and discharge electrode 20, still set up between discharge electrode 20 and air outlet, all can make the flow of air in the cavity that discharges 11 receive the hindrance, around deep bead 30, the air can form complicated air current for partial air is held up by deep bead 30 and is flowed at discharge electrode 20 periphery simultaneously, and the time that the air was purified by discharge electrode 20 increases, thereby improves air purification efficiency.

It can be understood that the arrangement mode of the discharge electrode 20 in the discharge cavity is not unique, and the discharge electrode may be arranged at any included angle with the air inlet direction of the air inlet, as long as the discharge electrode can realize the air purification under the condition of the high-voltage power supply connection. And in order to realize the sheltering from of air, the wind guard 30 should be a certain contained angle setting with the air inlet direction of air intake, also be more than 0 degree with the contained angle between the plane that the surface that wind guard 30 is used for sheltering from the air is located and be less than 180 degrees for the surface plane nonparallel that wind guard 30 is used for sheltering from the air is located to the air inlet direction, and then makes the air sheltered from by the wind guard. For example, in a more detailed embodiment, the wind shielding plate 30 may be disposed at an angle of 90 degrees with respect to the air inlet direction of the air inlet, and the plane of the surface of the wind shielding plate 30 for shielding air is perpendicular to the air inlet direction, so as to provide an optimal blocking effect for air.

The number and size of the vent holes formed in the wind deflector 30 are not unique, and only when the wind deflector 30 is required to block part of air, part of air can directly flow through the wind deflector 30 through the vent holes. For example, in one embodiment, more than two ventilation holes may be disposed on the wind deflector 30, and the diameters of the ventilation holes are much smaller than the air inlet and outlet of the discharge cavity 11.

It should be noted that the specific structure of the fixing bracket 10 is not exclusive as long as the fixing bracket 10 can form a discharge chamber 11 type having an air inlet and an air outlet. For example, in one embodiment, the fixing bracket 10 may have a hexahedral structure with opposite side surfaces opened. In other embodiments, the fixing support 10 may also be a ball structure having two openings, or the like.

Similarly, the specific structure of the discharge chamber 11 is not unique, and the structure of the discharge chamber 11 may be different according to the specific structure of the fixing bracket 10. For example, in one embodiment, when the fixing bracket 10 has a hexahedral structure with two opposite side surfaces open, the discharge chamber 11 is a rectangular parallelepiped space.

Referring to fig. 2, in one embodiment, the discharge electrode 20 includes a metal rod 21, an insulating layer (not shown) and a conductive line 22, the metal rod 21 is fixedly disposed in the discharge chamber 11, the conductive line 22 is wound around the metal rod 21, the insulating layer is disposed between the conductive line 22 and the metal rod 21, the metal rod 21 is connected to a power source, and the conductive line 22 is grounded.

Specifically, in the embodiment, the discharge electrode 20 is in a rod-shaped electrode structure, the metal rod 21 is used as a high-voltage electrode to be connected to a power supply, and the conductive wire 22 is used as a low-voltage (grounding) electrode to be grounded, so that when the power supply is used for supplying power to the high-voltage electrode, a discharge operation can be realized, and thus, air can be purified. Meanwhile, the conductive wire 22 is wound on the outer surface of the rod electrode as a low voltage electrode, and the two electrodes are insulated by an insulating layer, so that the discharge electrode 20 is in full contact with air, and the air purification efficiency can be further improved.

It should be noted that the specific types of metal rod 21 and conducting wire 22 are not exclusive, and in one embodiment, metal rod 21 and conducting wire 22 may be implemented by using the same conducting metal, such as copper metal. In other embodiments, the metal rod 21 and the conductive wire 22 may be implemented by different conductive metals, as long as the discharge electrode 20 formed by the metal rod 21 and the conductive wire 22 can effectively discharge electricity, so as to implement the air purification operation.

It is to be understood that the manner in which the conductive wire 22 is wound on the outer surface of the metal rod 21 is not exclusive, and in one embodiment, it may be implemented in a spiral winding manner. The type of insulation between the metal rod 21 and the conductive wire 22 is not exclusive, and since the metal rod 21 and the conductive wire 22 are discharged during operation, the temperature is increased accordingly, and in one embodiment, a high temperature resistant type insulation material may be used as the insulation material.

Referring to fig. 3, in an embodiment, the number of the discharge electrodes 20 is more than two, and the discharge electrodes 20 are fixedly disposed in the discharge cavity 11 in a staggered manner.

Specifically, the staggered arrangement of the discharge electrodes 20 means that the arrangement of the discharge electrodes 20 in the discharge cavity 11 is staggered from each other, so as to avoid that, in two adjacent rows of discharge electrodes 20, the projection of the discharge electrode 20 in the upper row coincides with the projection of the discharge electrode 20 in the lower row in the air blowing direction, that is, the discharge electrodes 20 in different rows are arranged by using a blanking method. Through the arrangement of the plurality of discharge electrodes 20, the air entering the discharge cavity 11 can be purified under the action of the plurality of discharge electrodes 20 at the same time, and the efficiency of air purification is effectively improved. In this embodiment, the discharge electrodes 20 are fixedly disposed in the discharge cavity 11 in a staggered manner, which is beneficial for air to fully contact with the discharge electrodes 20, thereby further improving air purification efficiency.

In one embodiment, the windshield 30 is an insulated windshield.

Specifically, the type of the wind deflector 30 is not exclusive, and in this embodiment, the wind deflector 30 made of an insulating material is used, and after a certain amount of pollutants are accumulated in the insulating wind deflector in the air purification process, since the pollutants cannot guide away the electric field in time, after the electric field is accumulated to a certain amount, an electric field opposite to the original electric field, that is, a back corona electric field, is formed. Because the electric field of back corona is opposite with the air inlet direction, can prolong the time that the air passes through insulating deep bead (or say through discharge cavity 11), and then prolonged the purification treatment time to the air. That is, by the provision of the insulating wind deflector, back corona may be formed by the contaminants adhering to the insulating wind deflector. Because the wind shield 30 is an insulating medium, after a certain amount of charged particles are accumulated, positive potential is easily formed on the surface of the medium, when the positively charged particles approach the wind shield 30, the like particles repel each other to force the charged polluted gas to move towards the electrode direction, and the purification cycle number is increased, so that the purification efficiency is effectively improved.

Further, in one embodiment, referring to fig. 3, the number of wind deflectors 30 is two or more.

Specifically, in this embodiment, a plurality of wind deflectors 30 are disposed in the discharge cavity 11, and the air flowing into the discharge cavity 11 is blocked by the plurality of wind deflectors 30, so that the resistance to the air in the discharge cavity 11 can be further increased by increasing the number of wind deflectors 30, and the time of the air in the discharge cavity 11 is further increased, thereby further improving the air purification efficiency.

It should be noted that the arrangement of the plurality of wind deflectors 30 in the discharge cavity 11 is not exclusive, and the arrangement may be different according to the specific shape of the wind deflectors 30. In one embodiment, when the number of the discharge electrodes 20 is two or more and the discharge electrodes 20 are staggered, the wind shielding plates 30 may be disposed between the discharge electrodes 20, so that a portion of the air is intercepted by the wind shielding plates 30 and flows around the discharge electrodes 20, and the time of the air purification treatment by the discharge electrodes 20 may be prolonged, thereby further improving the purification efficiency.

It can be understood that the arrangement direction of each wind deflector 30 in the purification cavity is not unique, as long as the included angle between the wind deflector 30 and the wind inlet direction of the wind inlet is greater than 0 degree and less than 180 degrees, the wind deflector can block the inflowing air, for example, in one embodiment, the arrangement direction of each wind deflector 30 is the same.

Specifically, the installation direction of the wind deflector 30 is an included angle between a plane of a surface of the wind deflector 30 for blocking air and the air inlet direction. In this embodiment, the wind deflectors 30 are all arranged along the same direction, so that when the air flowing in from the air inlet is blocked by the wind deflectors 30, part of the air still flows into the rear wind deflector 30 through the ventilation opening of the wind deflector 30, so that the air can flow out from the air outlet at a lower speed in the discharge cavity 11, and the purification operation of the flowing air is realized.

For example, in a more detailed embodiment, the wind deflectors 30 may be arranged in a direction perpendicular to the air inlet direction, that is, the plane of the wind deflectors 30 for blocking air is arranged opposite to the air inlet, so that the air flowing in from the air inlet blows toward the wind deflectors 30 perpendicularly. The arrangement of the wind deflector 30 can maximize the blocking capability of the wind deflector 30 for the inflowing air, so that the air can stay in the discharge cavity 11 as much as possible for purification treatment.

In another embodiment, the wind deflectors 30 may be arranged in different directions, and in this arrangement, the air flowing into the discharge cavity 11 is blocked by the wind deflectors 30, and at the same time, a more complex airflow can be formed, so that the high residence time of the air in the discharge cavity 11 can be further increased, and the air purification efficiency can be further improved.

The specific type of the fixing bracket 10 is not exclusive, and in one embodiment, referring to fig. 4, the fixing bracket 10 includes a first fixing plate 12, a second fixing plate 13, a first supporting plate 14 and a second supporting plate 15, the first fixing plate 12 and the second fixing plate 13 are disposed opposite to each other, a first end of the discharge electrode 20 is fixedly disposed on the first fixing plate 12, a second end of the discharge electrode 20 is fixedly disposed on the second fixing plate 13, and the first supporting plate 14 and the second supporting plate 15 are fixedly disposed between the first fixing plate 12 and the second fixing plate 13, so that the discharge electrode 20 is disposed in the discharge cavity 11 surrounded by the first fixing plate 12, the second fixing plate 13, the first supporting plate 14 and the second supporting plate 15.

Specifically, in the present embodiment, a cuboid box with two open sides is built by using a first fixing plate 12, a second fixing plate 13, a first supporting plate 14 and a second supporting plate 15, the internal space of the cuboid box is used as a discharge cavity 11, two open sides of the cuboid box are respectively used as an air inlet and an air outlet, and the discharge electrode 20 and the wind deflector 30 are both disposed inside the cuboid box. Through the arrangement of the fixing support 10 with the structure, the inner space of the discharge cavity 11 is large enough, the arrangement of a plurality of discharge electrodes 20 and a plurality of wind shields 30 can be met, meanwhile, the air inlet and the air outlet are also large enough, and sufficient air can be ensured to flow into the discharge cavity 11 for purification operation.

Further, in an embodiment, the fixing bracket 10 is further provided with a high voltage electrode interface 16 and a low voltage electrode interface 17, and the discharge electrode 20 disposed in the discharge wall 11 is connected to a high voltage power supply through the high voltage electrode interface 16 and grounded through the low voltage electrode interface 17, respectively, so as to implement the power-on operation of the discharge device. It is to be understood that the positions of the high voltage electrode interface 16 and the low voltage electrode interface 17 are not exclusive and are not limited to the second support plate 15 shown in fig. 4, and may be disposed on any one of the first fixing plate 12, the second fixing plate 13, and the first support plate 14, or disposed on any two of the first fixing plate 12, the second fixing plate 13, and the first support plate 14, respectively.

Similarly, the specific structure of the wind deflector 30 is not unique, and wind deflectors 30 with different structural types can generate complex air flows with different degrees in the air entering the discharge cavity 11, so that the air stays in the discharge cavity 11 for a longer time, and the air purification efficiency is effectively improved. In one embodiment, the surface of the windshield 30 that is used to block air is wavy in cross-section.

Specifically, referring to fig. 5, in the solution of this embodiment, the cross section of the surface of the wind shield 30 for shielding air is in a wave shape, so that the smooth flowing performance of air can be improved, and the local concentration of air is reduced, so that the air can flow better in the discharge cavity 11, and then is purified by the discharge electrode 20. This kind of structure type's deep bead 30, increase air resistance as far as possible, make the air form complicated air current around discharge electrode 20 and realize high efficiency air purification, the structure that a plurality of discharge electrode 20 staggered arrangement that can also be better set up for deep bead 30 can be reasonable set up between each discharge electrode 20.

In another embodiment, the surface of the windshield 30 that is used to block air has a dogleg shape in cross-section. Specifically, the zigzag shape may be a shape similar to a sawtooth wave or a shape similar to a rectangular wave, and no matter the shape is similar to a sawtooth wave or a shape similar to a rectangular wave, the air baffle 30 can increase air resistance, so that the air forms a complex airflow around the discharge electrodes 20 to realize high-efficiency air purification, and simultaneously, the structure in which the plurality of discharge electrodes 20 are arranged in a staggered manner can be better matched, so that the air baffle 30 can be reasonably arranged between the discharge electrodes 20.

It will be appreciated that other types of structures for the wind deflector 30 can be used in other embodiments, such as a linear cross-section of the surface for air shielding. For example, the air purification device may be disposed in the discharge chamber 11 to increase air resistance and form a complex air flow around the discharge electrode 20 to achieve high efficiency air purification.

In order to facilitate understanding of the technical solutions of the present application, the following detailed reception description of the present application is provided in connection with the most detailed embodiments.

Referring to fig. 3 and 4, a rectangular box with two open sides is formed by the first fixing plate 12, the second fixing plate 13, the first supporting plate 14 and the second supporting plate 15, the two open sides are an air inlet and an air outlet, the number of the discharge electrodes 20 is more than two, and the discharge electrodes 20 are arranged in the discharge cavity 11 in a staggered manner. Meanwhile, a plurality of insulating wind shields are arranged in the discharge cavity 11, the surfaces of the insulating wind shields used for blocking air are opposite to the air inlet (namely, the surfaces of the insulating wind shields are vertical to the air inlet direction), and the cross sections of the surfaces of the insulating wind shields used for blocking air are all in a wave shape. In the discharge device with such a structure, the discharge electrode 20 is wound around the conductive rod by using the conductive wire 22 to increase the contact area between the discharge electrode 20 and the air. When the discharge device operates, air flows in from the air inlet and is sequentially blocked by the wind shielding plates 30, and complex airflow appears around each wind shielding plate 30, so that part of the air is intercepted by the wind shielding plates 30 and flows around the discharge electrode 20, and the air purification treatment time of the discharge electrode 20 can be prolonged. And, because the existence of insulating deep bead, at the in-process that carries out air purification, insulating deep bead because the pollutant can not in time be led away the electric field after accumulating certain pollutant, can form the electric field opposite with former electric field after the electric field accumulates a certain amount, also forms back corona electric field promptly. Because the electric field of back corona is opposite with the air inlet direction, can prolong the time that the air passes through insulating deep bead (or say through discharge cavity 11), and then prolonged the purification treatment time to the air. That is, by the provision of the insulating wind deflector, back corona may be formed by the contaminants adhering to the insulating wind deflector. Because the wind shield 30 is an insulating medium, after a certain amount of charged particles are accumulated, positive potential is easily formed on the surface of the medium, when the positively charged particles approach the wind shield 30, the like particles repel each other to force the charged polluted gas to move towards the electrode direction, and the purification cycle number is increased, so that the purification efficiency is effectively improved.

In the discharge device, the discharge electrode 20 and the wind shield 30 are provided in the discharge chamber 11 formed by the fixed bracket 10, and the resistance to the air flow is increased by the presence of the wind shield 30. When air enters the discharge cavity 11 from the air inlet, the wind shield 30 obstructs the air flow, so that a complex airflow occurs around the wind shield 30, and a part of the air is intercepted by the wind shield 30 and flows around the discharge electrode 20, so that the air purification treatment time of the discharge electrode 20 can be prolonged. Above-mentioned scheme, the purification treatment time of multiplicable air in discharge chamber 11 to harmful substance such as formaldehyde, dust in the air is clear away as far as, has effectively improved air purification efficiency.

An air purification device comprises the discharge device.

Specifically, the fixing bracket 10 is a frame for fixing the discharge electrode 20 and the wind shield 30, and the discharge electrode 20 is a discharge device for removing harmful substances such as formaldehyde and dust in the air by discharging in a glow discharge manner or a plasma discharge manner, thereby purifying the air. After the fixed support 10 is built to form the discharge cavity 11 with the air inlet and the air outlet, air flows into the discharge cavity 11 from the air inlet under the action of a fan and the like, the discharge electrode 20 in the discharge cavity 11 performs air purification operation, and finally purified air flows out through the air outlet. When being provided with the deep bead 30 in the cavity that discharges 11, no matter the deep bead 30 sets up between air intake and discharge electrode 20, still set up between discharge electrode 20 and air outlet, all can make the flow of air in the cavity that discharges 11 receive the hindrance, around deep bead 30, the air can form complicated air current for partial air is held up by deep bead 30 and is flowed at discharge electrode 20 periphery simultaneously, and the time that the air was purified by discharge electrode 20 increases, thereby improves air purification efficiency.

It should be noted that the specific structure of the fixing bracket 10 is not exclusive as long as the fixing bracket 10 can form a discharge chamber 11 type having an air inlet and an air outlet. For example, in one embodiment, the fixing bracket 10 may have a hexahedral structure with opposite side surfaces opened. In other embodiments, the fixing support 10 may also be a ball structure having two openings, or the like.

Similarly, the specific structure of the discharge chamber 11 is not unique, and the structure of the discharge chamber 11 may be different according to the specific structure of the fixing bracket 10. For example, in one embodiment, when the fixing bracket 10 has a hexahedral structure with two opposite side surfaces open, the discharge chamber 11 is a rectangular parallelepiped space.

In the air purification device, the discharge electrode 20 and the wind shield 30 are arranged in the discharge cavity 11 formed by the fixed bracket 10, and the resistance of air flow is increased due to the existence of the wind shield 30. When air enters the discharge cavity 11 from the air inlet, the wind shield 30 obstructs the air flow, so that a complex airflow occurs around the wind shield 30, and a part of the air is intercepted by the wind shield 30 and flows around the discharge electrode 20, so that the air purification treatment time of the discharge electrode 20 can be prolonged. Above-mentioned scheme, the purification treatment time of multiplicable air in discharge chamber 11 to harmful substance such as formaldehyde, dust in the air is clear away as far as, has effectively improved air purification efficiency.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
