Just as the background art said, when adopting the air purifier among the prior art, if use for a long time, air purifier can appear the problem that purifying performance descends gradually, and utility model people's research discovers, and the root cause that appears this kind of problem lies in, and the plate electrode that forms the electric field also is the collection dirt surface simultaneously. After air purifier purified air for a long time, electrode plate surface can accumulate more dust as the collection dirt surface, and electrode plate surface can be corroded by the dust of accumulation, causes irreversible corrosion damage, and then can reduce the dust removal ability of electric field.
As shown in fig. 1, for the above reasons, in an embodiment of the present invention, an air purification apparatus 200 is provided, which includes a corona mechanism 210 and a dust collecting mechanism 100. The corona mechanism 210 is used to charge dust in the air flow, the dust collecting mechanism 100 provides a dust collecting electric field, so that the charged dust enters the dust collecting electric field and stays in the dust collecting mechanism 100 under the action of the electric field force, and the dust-removed and purified air flow is discharged from the dust collecting mechanism 100, thereby realizing the dust removing function of the air purifying device 200.
The corona mechanism 210 has an ionization region 211 for charging dust in the air flow, the dust collecting mechanism 100 includes an air flow passage 11, the ionization region 211 communicates with the air flow passage 11, and the air flow enters the air flow passage 11 after passing through the ionization region 211. In this way, the air flow passes through the corona mechanism 210 to charge the dust, and then enters the air flow channel 11 of the dust collecting mechanism 100, so as to adsorb the charged dust by the dust-removing electric field applied in the air flow channel 11, thereby achieving the dust-removing effect. Alternatively, corona mechanism 210 is an ionizer, or a discharge tip, or the like.
The dust collecting mechanism 100 includes at least two electrodes 10, and every two adjacent electrodes 10 are opposite and spaced to form an air flow channel 11 therebetween. Wherein, at least two electrodes 10 are alternately applied with low voltage and high voltage in the interval direction, so that a dust removing electric field is formed in the airflow channel 11. That is, after the low voltage and the high voltage are alternately applied to the two adjacent electrodes 10, a potential difference is generated between the two adjacent electrodes 10, and then a dust removing electric field is formed in the airflow channel 11.
The dust collecting mechanism 100 further comprises a dust collecting assembly 30, the dust collecting assembly 30 is disposed in the airflow channel 11, and the dust collecting assembly 30 is blocked on a moving path of the charged particles moving in the dust removing electric field. That is, the dust collecting assembly 30 in the airflow channel 11 is simultaneously in the dust collecting electric field, so as to block the charged particles (e.g., dust) moving under the action of the dust collecting electric field, make the dust stay on the dust collecting assembly 30, and further purify the air. Collect the dust through collection dirt subassembly 30 like this, no longer utilize the surface of electrode 10 itself to collect the dust, prevent that the electrode 10 surface from being corroded after collecting more dust, prevent that the dust collection electric field's dust collection ability from declining because electrode 10 is corroded, along with the extension of live time, the dust collection effect of collection dirt mechanism 100 still can remain stable, makes the purifying effect of air evolution ware remain stable, and purifying effect is better.
It should be noted that the number of the electrodes 10 is at least two, for example, two, three, or four, and it is only necessary to arrange every two adjacent electrodes 10 at intervals, and apply positive voltage and negative voltage alternately to every two adjacent electrodes 10 to form a dust removing electric field.
As shown in fig. 2, at least two electrodes 10 include repellers 12 and acceptors 14 alternately arranged along the spacing direction, and a dust-removing electric field is formed between adjacent repellers 12 and acceptors 14, and charged particles in the dust-removing electric field move toward the direction close to the acceptors 14. That is, after entering the dust removing electric field, the charged particles move away from the repeller 12 and move closer to the receiver 14 by the force of the electric field.
Moreover, the dust collection assembly 30 comprises a dust collection belt 32, the dust collection belt 32 shields at least part of the surface of the receiving electrode 14 facing the repeller 12, the dust which is about to reach the receiving electrode 14 is intercepted by the dust collection belt 32, the dust is collected on the dust collection belt 32, the dust is prevented from being accumulated on the surface of the receiving electrode 14, and the dust removal capability of the dust removal electric field is ensured to be stable. In a first embodiment, as shown in fig. 1, the electrode 10 is plate-shaped, and the dust collection belt 32 is disposed in a strip shape to accommodate the surface of the plate-shaped electrode 10 facing the dust removing electric field; in the second embodiment, as shown in fig. 3, the electrode 10 is in a cylindrical shape, and the dust collecting belt 32 is adapted to the surface of the cylindrical electrode 10 facing the dust removing electric field, and semi-surrounds the outer periphery of the electrode 10. Therefore, the shape of the dust collecting belt 32 is not limited herein, and the shape of the electrode 10 can be adapted to block dust before the electrode 10.
Alternatively, when the motor 10 is plate-shaped, the dust collection belt 52 may shield the receiving pole 14 in various forms. For example, as shown in fig. 1, the dust collecting belt 52 is only shielded from the side of the receiving electrode 14 facing the dust collecting electric field, or as shown in fig. 5-6, the dust collecting belt 52 is wrapped around the circumference of the receiving electrode 14, and the dust collecting belt 52 is connected end to end, and one part of the dust collecting belt 52 is located in the dust collecting electric field and the other part is located outside the dust collecting electric field. In the embodiment shown in fig. 5 to 6, the dust collection belt 52 is wound around the outer periphery of the electrode plate in the longitudinal direction thereof, but it should be understood that in some other embodiments, the dust collection belt 52 may be wound around the outer periphery of the electrode plate in the width direction thereof, and the winding direction of the dust collection belt 52 is not limited herein, and at least a part of the surface of the receiving electrode 14 facing the dust removal electric field may be shielded.
In this embodiment, the number of the dust collecting assemblies 30 is plural, a plurality of dust collecting assemblies 30 are disposed in at least one dust removing electric field, and the plurality of dust collecting assemblies 30 are blocked at different positions of the dust removing electric field, so that the dust in the dust removing electric field is intercepted by the plurality of dust collecting assemblies 30, thereby improving the dust removing capability. Moreover, the dust collecting assembly 30 is a non-charged component, and the dust collecting assembly 30 does not influence the dust removing electric field.
As shown in fig. 4-6, the dust collection belt 32 includes an active section 321 and a standby section 323 connected to each other, and the active section 321 and the standby section 323 are alternately switched to face the dust removal electric field by an external force. That is, one of the active segment 321 and the standby segment 323 faces the dust removing electric field for intercepting dust in the dust removing electric field for a period of time. And, in another period of time, the other one of the active segment 321 and the standby segment 323 may be switched to face the dust removing electric field by external force driving to replace the previous one for intercepting dust in the dust removing electric field. In this way, the standby section 323 and the active section 321 can be switched to use, one is used for intercepting dust, the other is standby, when one for intercepting dust needs to be replaced, the standby section is switched to be used for intercepting dust through external force driving, and the standby section and the active section are alternately used, so that the service time of the dust collection belt 32 is prolonged, and the cleaning times are reduced. It should be noted that the definitions of the active segment 321 and the standby segment 323 are relative. For example, before the dust collection belt 32 moves, the active section 321 faces the dust removal electric field, and the standby section 323 faces away from the dust removal electric field; after the dust collecting belt 32 moves, the previous active segment 321 moves to the opposite direction of the dust removing electric field, corresponding to the current spare segment 323, and the previous spare segment 323 moves to the opposite direction of the dust removing electric field, corresponding to the current active segment 321.
Further, the currently active section 321 facing the dust removal electric field can be moved out of the dust removal electric field under the action of an external force; the dust collection mechanism 100 further includes a cleaning assembly 50, the cleaning assembly 50 being adapted to clean the active section 321 removed from the de-dusting electric field. After the current active segment 321 is used in the dust removing electric field for a period of time, the dust accumulated on the active segment 321 is more, so that the standby segment 321 can be switched to face the dust removing electric field, and meanwhile, the active segment 321 is moved out of the dust removing electric field, and the dust on the active segment 321 is cleaned outside the dust removing electric field through the cleaning assembly 50. Similarly, when the previous standby segment 323 moves into the dedusting electric field as the current active segment 321, after a period of time in the dedusting electric field, the clean current active segment 323 can be switched to face the dedusting electric field, and the current active segment 323 moves out of the dedusting electric field, so as to clean the current active segment 323 by the cleaning assembly 50.
So, when current active section 321 shifts out the dust removal electric field under the exogenic drive, can be cleared up by clearance subassembly 50 dust, can clear up collection dirt area 32 on line, need not dismantle collection dirt area 32, and it is convenient to wash. If necessary, the dust collection belt 32 may be detached and cleaned.
Alternatively, as shown in fig. 5-6, the dust collecting belt 32 is disposed end-to-end between the repeller 12 and the collector 14, and the active segment 321 and the standby segment 323 rotate circularly around the collector 14, circulate into the dust collecting electric field, and move circularly to the cleaning assembly 50 to clean the dust, and recycle the dust collecting belt 12 to collect the dust, thereby reducing the frequency of replacing the dust collecting belt 32 and increasing the service time of the dust collecting belt 52.
As shown in fig. 7, it is to be understood that in other embodiments, the dust collection belt 32 is disposed end-to-end separately between the repeller 12 and the receptor 14, the dust collection belt 32 extends lengthwise, and the dust collection belt 32 reciprocates bi-directionally in its direction of extension. For example, the active section 321 is located in the dust collecting electric field for dust removal, and the standby section 323 is located outside the dust collecting electric field and has been cleaned by the cleaning assembly 50; when the dust collecting belt 32 is moved to the left, the standby section 323 enters the dust collecting electric field to become the current active section, and the previous active section 321 is removed from the dust collecting electric field and then cleaned by the cleaning assembly 50 to become the current standby section; the dust belt 52 is then moved to the right, the previously used section 323 enters the dusting electric field to the right, and the previously active section is moved out of the dusting electric field to the right again for cleaning. Thus, moving the dust collecting belt 32 left and right can continuously move the current active section 321 left and right out of the dust removing electric field, and can clean the dust on the current active section 321 online. And, set up two sets of clearance subassemblies 50 respectively in the left and right sides of dust removal electric field, clear up the current active section that shifts out the dust removal electric field left respectively and shifts out the dust removal electric field right.
The cleaning assembly 50 comprises a spray nozzle 52 and a dryer 54, the spray nozzle 52 and the dryer 54 are sequentially arranged along the transmission direction of the dust collection belt 32, the moving dust collection belt 32 is firstly cleaned through the spray nozzle 52 and then dried through the dryer 54, and then the cleaning work can be completed. It is understood that in other embodiments, the dirt collection belt 32 is made of a fire retardant material and the cleaning assembly 50 includes a torch 56, and the torch 56 burns and cleans the dirt on the dirt collection belt 32, so that the dust cleaning operation can be completed in one step.
Specifically, as shown in fig. 1-2 and 7, the dust collection belt 32 is disposed between the repeller 12 and the receptor 14 end to end, and is driven in one direction or two directions relative to the receptor 14 under the action of external force; alternatively, as shown in fig. 5-6, the dust collection belt 32 is disposed end-to-end between the repeller pole 12 and the collector pole 14 and is driven in circulation around the collector pole 14 by an external force. The dust collecting belt 32 can be driven by external force, and the driving mode of the dust collecting belt 32 is not limited herein as long as the active section 321 and the standby section 323 can be switched to face the dust removing electric field by the driving of the dust collecting belt 32.
As shown in fig. 3, the dust collection assembly 30 further comprises a plurality of driving wheels 34, the plurality of driving wheels 34 providing a winding base for the dust collection belt 32, and the dust collection belt 32 is wound outside the plurality of driving wheels 34 for collecting dust in the airflow. Optionally, the dust collection belt 32 is a non-woven fabric, which facilitates cleaning. Moreover, the dust collection belt 32 is detachably wound outside the transmission wheel 34, so that when the dust on the dust collection belt 32 is much, the dust collection belt 32 can be detached from the transmission wheel 34 and then cleaned, and the cleaning is convenient.
The driving wheels 34 drive the active section 321 and the standby section 323 to alternately switch to face the dust removing electric field, and the dust collecting belt 32 sleeved outside the driving wheels 34 is driven to move by the rotation of at least one driving wheel 34 in the driving wheels 34.
In some of these embodiments, the plurality of drive wheels 34 includes a first winding wheel 341 and a second winding wheel 343, the first winding wheel 341 being located at a leading end of the dust collection belt 32, the second winding wheel 343 being located at a trailing end of the dust collection belt 32, one of the first and second winding wheels 341 and 343 winding the standby section 323 thereon, the other of the first and second winding wheels 341 and 343 being for winding the active section 321 upon release of the standby section 323.
As such, the standby section 323 may be wound on one of the first and second winding wheels 341 and 343, and the active section 321 faces the dust removing electric field for dust interception. Then, by the driving of the driving wheel 34, the standby segment 323 is released and faces the dust removing electric field, the standby segment 323 performs dust interception, and the active segment 321 is wound on the other one of the first and second winding wheels 341 and 343. Thus, the standby section 323 or the active section 321 is wound, so that the standby section 323 and the active section 321 are switched, and the dust collection belt 32 is convenient to collect and arrange.
Specifically, in the embodiment shown in fig. 1, the airflow channel 11 includes an airflow inlet 112 and an airflow outlet 114 that are communicated with each other, the airflow direction of the airflow inlet 112 intersects with the direction of the acting force of the dust removing electric field on the charged particles, and the dust collecting assembly 30 is disposed along the direction from the airflow inlet 112 to the airflow outlet 114 and extends lengthwise, so that the extending direction of the dust collecting assembly 30 is not greatly different from the airflow flowing direction, and the dust collecting assembly 30 does not generate too much resistance to the airflow, thereby preventing the dust collecting assembly 30 from generating too much influence on the airflow velocity.
As shown in fig. 3, the dust collecting assembly 30 further includes a guide wheel 36, the guide wheel 36 abuts against the dust collecting belt 32 to apply a pre-tightening force to the dust collecting belt 32, so as to prevent the dust collecting belt 32 from loosening, and to keep the dust collecting belt 32 to intercept dust from the dust collecting electric field on a flat ground, thereby ensuring a dust removing effect. Specifically, the dust collection belt 32 is a flexible member, and the guide wheels 36 can be disposed at different positions according to actual requirements to guide the dust collection belt 32 to a proper position while keeping the dust collection belt 32 flat.
Further, the guide wheel 36 is disposed on one of the plurality of driving wheels 34 close to the airflow inlet 112, the guide wheel 36 is located on one side of the current driving wheel 34 close to the airflow inlet 112, the guide wheel 36 and the dust collection belt 32 between the current driving wheel 34 form a wind guiding section 35, and the wind guiding section 35 is disposed obliquely with respect to the airflow direction at the airflow inlet 112 to better guide the airflow so as to make more airflow gather and flow into the airflow channel 11.
Alternatively, the diameter of the guide wheel 36 is smaller than that of the transmission wheel 34 connected with the guide wheel, so that the conical air guide section 35 is formed, the resistance of the air flow passing through the guide wheel 36 is reduced, and the air flow enters the air flow channel 11 more smoothly.
In some embodiments, the dirt collection assembly 30 can be removably positioned to facilitate cleaning and replacement of the dirt collection assembly 30. When more dust is accumulated on the dust collecting component 30, the dust collecting electric field can be detached from the dust collecting component 30, so that the dust on the dust collecting component 30 can be conveniently cleaned, and meanwhile, the dust collecting component 30 of the rod can be conveniently replaced on the detached installation position.

The dust collecting mechanism 100 includes at least two electrodes 10, and every two adjacent electrodes 10 are opposite and spaced to form an air flow channel 11 therebetween. Wherein, at least two electrodes 10 are alternately applied with low voltage and high voltage in the interval direction, so that a dust removing electric field is formed in the airflow channel 11. That is, after the low voltage and the high voltage are alternately applied to the two adjacent electrodes 10, a potential difference is generated between the two adjacent electrodes 10, and then a dust removing electric field is formed in the airflow channel 11.
