Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and in particular to an impeller type plasma generator structure. Background Art

[0002] At present, plasma air purifiers are mainly composed of filters, fans, plasma modules and other functional components. Among them, fans and plasma modules are the main functional components of plasma air purifiers, and the structural design is mainly developed around these two modules. The structures of fans and plasma modules are relatively mature and fixed. The air circulation volume of the fans and the purification effect of the plasma modules are proportional to the size of their respective modules. It is difficult to achieve a double breakthrough in size and effect based on existing technology. The component structure of existing plasma air purifiers is irregular and uniform, and the components cannot be completely sealed and matched. During operation, it is easy for unsterilized air to be sent out through the gaps, resulting in a blind spot for disinfection. At the same time, the existing plasma structure can charge the particles in the air during use. Under the action of the high-voltage electric field, the grounding electrode will absorb a large amount of dust over time, requiring regular cleaning and maintenance. Summary of the Invention

[0003] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide an impeller-type plasma generator structure. By adding conductive electrodes between multiple groups of blades of the fan impeller, the plasma module function is realized without affecting the existing function of the fan, saving the space occupied by the independent design of the plasma module structure. Under the condition of the same purification effect, the plasma air purifier is miniaturized and integrated. At the same time, the integrated setting of the impeller and the plasma module also achieves all-round and no-dead-angle disinfection of the incoming air, thereby improving the one-time disinfection efficiency. At the same time, when the plasma module is in operation, it will charge the particles passing through. Under the action of the deflected electric field, they will be adsorbed on the ground electrode, that is, the surface of the fan blade. After the charge is discharged through the ground electrode, the particles continue to adhere to the fan blade. When the fan blade rotates at high speed, the adsorbed dust is more easily desorbed under the dual action of centrifugal force and wind force, thereby extending the cleaning and maintenance cycle.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] A blade-type plasma generator structure includes multiple groups of blades, each of which is fixedly connected to a blade fixing ring piece on both sides of the multiple groups of blades. Multiple groups of conductive electrodes are arranged between two groups of blade fixing ring pieces, and the multiple groups of conductive electrodes are respectively arranged between each two groups of blades. The two sides of the two groups of blade fixing ring pieces are respectively fixedly connected to a fixed disc and a fixed base plate. A fixed ring is provided at the center of the fixed disc. A conductive slip ring is rotatably connected to the middle of the fixed ring. The conductive slip ring is connected to the multiple groups of conductive electrodes.

[0006] As a further solution of the present invention: the conductive electrode is S-shaped, and one end is connected to the conductive slip ring through an electrode connecting line, and the other end is S-shaped and passes through the fixed disc and the fixed chassis and is fixedly connected to the fixed chassis.

[0007] As a further solution of the present invention: the outer wall of the fixing ring is fixedly connected to a plurality of groups of connecting rods in an equidistant array, and one end of the plurality of groups of connecting rods away from the fixing ring is fixedly connected to the inner wall of the fixing disc.

[0008] As a further solution of the present invention: the fixed disc and the top of the connecting rod are both provided with wire grooves, and the conductive electrodes and the electrode connecting wires are both arranged in the wire grooves.

[0009] As a further solution of the present invention: a wire trough cover is provided on the top of the wire trough.

[0010] As a further solution of the present invention: one end of the fan blade away from the conductive slip ring is grounded.

[0011] As a further solution of the present invention: the fixed disc is made of insulating material.

[0012] Beneficial effects of the present invention:

[0013] 1. In the present invention, by adding conductive electrodes between multiple groups of blades of the fan impeller, the function of the plasma module is realized without affecting the existing function of the fan, saving the space occupied by the independent design of the plasma module structure. Under the condition of the same purification effect, the overall plasma air purifier is miniaturized and integrated. At the same time, the integrated setting of the impeller and the plasma module also achieves all-round and dead-angle disinfection of the incoming air, thereby improving the one-time disinfection efficiency. At the same time, during the operation of the impeller-type plasma generator, the particles adsorbed on the fan blades due to charge can be desorbed under the action of centrifugation, thereby extending the cleaning and maintenance cycle of the plasma module.

[0014] 2. In this invention, the plasma module charges particles passing through it during operation. These particles are then attracted to the ground electrode (i.e., the blade surface) by the deflected electric field. After the charge is removed from the ground electrode, the particles remain attached to the blade. When the blade rotates at high speed, the adsorbed dust is more easily desorbed by the combined effects of centrifugal force and wind, thus reducing cleaning frequency.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] like Figure 1-Figure 7 As shown, a wheel-type plasma generator structure includes multiple groups of fan blades 1, and fan blade fixing ring pieces 101 are fixedly connected on both sides of the multiple groups of fan blades 1. Multiple groups of conductive electrodes 2 are arranged between the two groups of fan blade fixing ring pieces 101. The multiple groups of conductive electrodes 2 are respectively arranged between each two groups of fan blades 1, reducing the space occupied by the structure and miniaturizing the module. The two sides of the two groups of fan blade fixing ring pieces 101 are respectively fixedly connected to a fixed disk 3 and a fixed chassis 6. The fixed disk 3 is made of insulating material. A fixed ring 301 is provided at the center of the fixed disk 3. A conductive slip ring 4 is rotatably connected in the middle of the fixed ring 301. The conductive slip ring 4 is connected to the multiple groups of conductive electrodes 2. The end of the fan blade 1 away from the conductive slip ring 4 is grounded.

[0026] like Figure 1 and Figure 7 As shown, the conductive electrode 2 is linear and S-shaped, and one end is connected to the conductive slip ring 4 through the electrode connecting wire 5, and the other end is S-shaped and passes through the fixed disc 3 and the fixed chassis 6 and is fixedly connected to the fixed chassis 6.

[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the outer wall of the fixed ring 301 is fixedly connected to multiple groups of connecting rods 302 in an equidistant array, and the ends of the multiple connecting rods 302 away from the fixed ring 301 are fixedly connected to the inner wall of the fixed disk 3 to support and fix the fixed ring 301. The tops of the fixed disk 3 and the connecting rods 302 are both provided with wire grooves 303, and the conductive electrodes 2 and the electrode connecting wires 5 are both arranged in the wire grooves 303. A wire groove cover 304 is provided on the top of the wire grooves 303 to protect the electrode connecting wires 5 and the conductive electrodes 2.

[0028] In the present invention, the conductive electrode 2 is not limited to a linear structure, and the conductive electrode 2 may also have a needle structure.

[0029] The present invention operates as follows: When blades 1 are driven by a drive device in a plasma air purifier, they rotate, drawing air from the gap between the air inlet and blades 1 into the center of blades 1 and then out through the air outlet. While blades 1 are operating, conductive slip rings 4 are energized, supplying power to conductive electrodes 2 via electrode connection lines 5. Multiple sets of conductive electrodes 2 are positioned between multiple sets of blades 1, disinfecting and sterilizing the air drawn in through them. The gaps between blades 1 are essential pathways for air to enter. Conductive electrodes 2 are positioned between multiple sets of blades 1, enabling comprehensive disinfection of the incoming air, avoiding blind spots. When the plasma module is in operation, particles passing through it become charged. These particles are then adsorbed to the ground electrode, i.e., the surface of blades 1, under the action of the deflected electric field. After the charge is removed through the ground electrode, the particles remain attached to blades 1. When blades 1 rotate at high speeds, adsorbed dust is more easily desorbed by the combined effects of centrifugal force and wind, thereby reducing cleaning frequency.
