In another embodiment, at least one of the first potential module 20 and the second potential module 30 is a high voltage module having a high potential by electrostatic induction. In one implementation, an inductive layer is disposed between the filter module 10 and the high voltage module, which is configured to have a high potential by electrostatic induction. For example, the first potential module 20 is not connected to a zero potential, the second potential module 30 is connected to the zero potential, and the first potential module 20 can generate a high potential through electrostatic induction through the induction layer, that is, the first potential module 20 is a high voltage module, and the second potential module 30 is a zero potential module.
The implementation manner of the high voltage module in the embodiment of the present invention includes various ways, and with continuing reference to fig. 1, one implementation manner is that the high voltage module includes: a conductive mesh 21 and a tungsten wire assembly 22. Wherein, the conductive mesh 21 and the tungsten wire assembly 22 are sequentially arranged along the air flowing direction. Wherein, one function of the conductive mesh 21 is to provide support for the tungsten wire assembly 22, and the tungsten wire assembly 22 maintains its shape under the support of the conductive mesh 21. Another function of the conductive mesh 21 is to form a high-voltage electric field with the tungsten wire assembly 22, for example, when the tungsten wire assembly 22 is energized, the conductive mesh 21 is connected to a zero potential, the energized tungsten wire assembly 22 has a high potential, and the high-voltage electric field is formed between the tungsten wire assembly 22 and the conductive mesh 21, so that part of components contained in the air can be charged.
Further, in an implementation manner of the tungsten wire assembly 22, the tungsten wire assembly 22 includes a plurality of tungsten wires arranged at intervals. One end of each of the plurality of tungsten wires is connected to the conductive member 23. The conductive member 23 can supply current to each of the tungsten filaments so that the voltages applied to the tungsten filaments are equal to each other, thereby preventing potential differences from being formed between the tungsten filaments.
In order to further fix the conductive member 23, in an implementable embodiment of the present invention, the tungsten wire assembly 22 further comprises a fixing frame. The holder comprises a first bracket 24 and a second bracket 25 which are oppositely positioned. The conductive member 23 is disposed on the first bracket 24. The plurality of tungsten wires are arranged in parallel between the first bracket 24 and the second bracket 25. For example, one end of the tungsten wire is connected to the first bracket 24 through the conductive member 23, and the other end is connected to the second bracket 25. A plurality of the tungsten wires are connected side by side between the first bracket 24 and the second bracket 25.
Further, in order to facilitate the user to disassemble the high voltage module, in an embodiment of the present invention, the fixing frame is provided with a handle 26 for the user to draw. When the user is in dismouting the high-voltage module, accessible handle 26 is grabbed firmly the high-voltage module, convenience of customers' operation has just saved extra assembly and disassembly tools.
Further, one end of the conductive mesh 21 is detachably connected to the first bracket 24. One way to achieve this is that a buckle is disposed at an edge of one end of the conductive mesh 21 connected to the first bracket 24, a slot is disposed at a corresponding position of the first bracket 24, and the conductive mesh 21 and the first bracket 24 are connected by engaging the buckle in the slot. When the conductive net is required to be detached, the buckle can be taken out of the clamping groove, and the conductive net 21 and the first support 24 are separated. Further, the other end of the conductive mesh 21 is detachably connected to the second holder 25. Implementation can refer to the connection with the first bracket 24.
Further, to prevent damage to the tungsten wire assembly 22 during use, in an implementable embodiment of the present invention, the tungsten wire assembly 22 further comprises: a protective cover 27. One end of the protective cover 27 is detachably connected to the first bracket 24, and the other end is detachably connected to the second bracket 25. The tungsten filaments are located in the space formed by the protective cover 27 and the conductive mesh 21. In an implementation manner, two end edges of the protection cover 27 are respectively provided with a buckle, the first bracket 24 and the second bracket 25 are provided with a slot at a position corresponding to the buckle, and the protection cover 27 is connected with the first bracket 24 and the second bracket 25 by clamping the buckle in the slot. When the protective cover needs to be detached, the fastener can be taken out of the clamping groove, so that the protective cover 27 is separated from the first support 24 and the second support 25. One function of the protective shell 27 is to provide protection for the tungsten wire assembly 22, and to prevent the tungsten wire assembly 22 from being damaged during use. Another function of the protective shell 27 is to form a high-voltage electric field with the tungsten wire assembly 22, for example, to energize the tungsten wire assembly 22, the protective shell 27 is switched on at a zero potential, the tungsten wire assembly 22 after being energized has a high potential, the high-voltage electric field is formed between the tungsten wire assembly 22 and the protective shell 27, and a high-voltage electric field is formed between the tungsten wire assembly 22 and the conductive mesh 21 to form a dual high-voltage electric field, so that part of components contained in the air can be charged. Optionally, the protective shell 27 does not conduct zero potential, and can also be used as a shielding layer.
With continued reference to FIG. 1, in one practical embodiment of the present invention, the filter module 10 is cylindrical. When the first electric potential module 20 is an electric potential module with a high electric potential, the first electric potential module 20 surrounds the outer side of the cylinder of the filter module 10. The second potential module 30 is cylindrical and is located inside the cylinder of the filter module 10.
Several implementations of the purification assembly provided by embodiments of the present invention are described in further detail below.
In an implementation, the first potential module 20 is a first high voltage module having a high potential, and the second potential module 30 is a first zero potential module. The high-voltage electric field generated between the first high-voltage module and the first zero potential module can eliminate various bacteria and viruses, ionizes air to generate ozone, and further realizes sterilization through the ozone. Meanwhile, the high-voltage electric field can sterilize the filtering module 10.
Further, in order to enable the bacteria or viruses passing through the high voltage electric field to be charged positively or negatively, in an implementable embodiment, the first high voltage module is a positive high voltage module or a negative high voltage module. When bacteria or viruses pass through a high-voltage electric field, the surfaces of the bacteria and the viruses are charged with a large amount of positive electricity or negative electricity, and after the electricity is charged, the bacteria and the viruses generate neutralization discharge to generate a large amount of energy to kill the bacteria or the viruses.
Further, in an implementation embodiment, a second zero potential module is further disposed on the upstream side of the first potential module 20. The first high-voltage module and the second zero potential module form a potential difference to form a first high-voltage electric field capable of sterilizing, the second high-voltage electric field is formed between the first high-voltage module and the first zero potential module, double sterilization is carried out through the first high-voltage electric field and the second high-voltage electric field, and triple purification is formed by matching the first high-voltage electric field and the second high-voltage electric field with the filtering module 10; meanwhile, the second high-voltage electric field can also sterilize the filter module 10. Meanwhile, the two high-voltage electric fields can generate trace ozone in the process of ionizing the ambient air, and the strong oxidizing property of the ozone can kill bacteria and viruses. It should be noted that, when the conductive net 21 is connected to a zero potential, the conductive net 21 may be used as a second zero potential module.
Further, in an implementation embodiment, a shielding layer is disposed between the first potential module 20 and the filtering module 10. The main function of the shielding layer is to keep the distance between the first voltage module 20 and the filtering module 10 within a predetermined range, so as to prevent the distance between the first high voltage module and the first zero voltage module from being too large, which results in too small concentration of generated ions. Further, a shielding layer may be disposed on the surface of the filter module 10. The first zero potential module is disposed on the surface of the filter module 10.
Further, in an implementation manner of the present invention, when the first potential module 20 is the first high voltage module and the second potential module 30 is the first zero potential module, a second high voltage module is further disposed on the upstream side of the airflow of the first potential module 20. The first high-voltage module and the second high-voltage module have potential difference. The positive and negative voltages between the second high-voltage module and the first high-voltage module can be opposite to form a potential difference, a first high-voltage electric field is formed between the first high-voltage module and the second high-voltage module, the first high-voltage module and the first zero potential module form a second high-voltage electric field, double sterilization is performed through the first high-voltage electric field and the second high-voltage electric field, and triple purification is performed on air through the filtering module 10 in a matching manner. Meanwhile, the second high-voltage electric field can sterilize the filtering module 10.
The positive and negative pressures between the second high-voltage module and the first high-voltage module are opposite, ions generated by the positive and negative voltages are more than those generated by the high-voltage module and a zero potential, and the sterilization effect is better. However, the cost of arranging the high-voltage modules with opposite polarities is high. In fact, to achieve the same effect, the voltage of the high voltage module needs to be doubled when the high voltage module is set in the zero potential mode. For example, doubling positive high pressure, such as 8000V to 0V, and positive and negative 4000V pressures do not differ significantly in the number of ions produced. For cost saving, the positive and negative pressures between the second high voltage module and the first high voltage module may be the same, for example, the second high voltage module includes a high voltage generator, and the high voltage generated by the high voltage generator can kill various bacteria.
Further, in an implementation manner of the present invention, when the first potential module 20 is the first high voltage module, and the second potential module 30 is the first zero potential module, a third high voltage module is further disposed on the downstream side of the airflow of the second potential module 30. The first high-voltage module and the first zero potential module have a potential difference therebetween to form a first high-voltage electric field capable of sterilizing, the third high-voltage module and the first zero potential module form a second high-voltage electric field therebetween, double sterilization is performed through the first high-voltage electric field and the second high-voltage electric field, and the filter module 10 is matched to perform triple purification on air. Further, a shielding layer for keeping the distance within a set range is disposed between the second potential module 30 and the third high voltage module.
Further, in an embodiment of the present invention, when the first potential module 20 is the first zero potential module and the second potential module 30 is the first high voltage module, a second high voltage module is further disposed on the upstream side of the first potential module 20. The second high-voltage module and the first zero potential module form a first high-voltage electric field, and the first high-voltage module and the first zero potential module form a second high-voltage electric field. Furthermore, a second zero potential module is arranged on the upstream side of the airflow of the second high-voltage module. And a third high-voltage electric field is generated between the second high-voltage module and the second zero-potential module, and the air is subjected to quadruple purification by matching the first high-voltage electric field, the second high-voltage electric field and the filtering module 10.
Further, in an embodiment of the present invention, when the first potential module 20 is the first zero potential module and the second potential module 30 is the first high voltage module, a second high voltage module is disposed on the upstream side of the first high voltage module; the second high-voltage module and the first high-voltage module have potential difference. Furthermore, a shielding layer for keeping the distance within a set range is arranged between the first high-voltage module and the second high-voltage module.
Further, in an implementation manner of the present invention, the first potential module 20 and the second potential module 30 are both high voltage modules having high potential. The first voltage module 20 has a positive high voltage potential to form a first high voltage module, and the second voltage module 30 has a negative high voltage potential to form a second high voltage module. Of course, the positive and negative properties of the first high voltage module and the second high voltage module may be the same or opposite. A high-voltage electric field is formed between the first high-voltage module and the second high-voltage module, and the filtering module 10 can be sterilized while air is sterilized.
Further, a shielding layer for keeping the distance within a set range is arranged between the first high voltage module and the filtering module 10. The shielding layer mainly functions to prevent the first high-voltage module from being too far away from the first zero potential module, so that the concentration of generated ions is too low.
Or, further, a first zero potential module is disposed on the upstream side of the first potential module 20. The first zero potential module and the first potential module 20 form a high voltage electric field to kill bacteria and viruses in the air.
Or, further, a third high-voltage module is disposed on the downstream side of the airflow of the second potential module 30; the second high-voltage module and the third high-voltage module have potential difference. A high voltage electric field is formed between the second voltage module 30 and the third voltage module. Furthermore, a shielding layer for keeping the distance within a set range is arranged between the second high voltage module and the third high voltage module.
The potential modules (including the first to third high-voltage modules and the first to third zero-potential modules), the filter module 10 and the shielding layer are combined in various ways according to different requirements to form the purification assembly in various forms.
The following table is a list of various potential modules of the purification assembly and different combinations of the filtration modules 10 according to the present invention.
