Description

Technical Field

[0001] This application belongs to the field of air filtration equipment, and specifically relates to an air conditioner filter element. Background Art

[0002] Traditional air conditioner filter elements generally adopt a multi-layer filter screen form to filter PM2.5 particles, bacteria, nitrogen oxides, and even extremely small particles down to 0.3 microns layer by layer. When the air flow of the existing air conditioner filter element flows through the honeycomb filter screen layer, the air flow mostly flows directly through the gaps and has less contact with the pore walls, resulting in poor adsorption and filtration effects. At the same time, negative oxygen ions are beneficial to the human body. They refer to oxygen ions with a negative charge, which are formed by the combination of oxygen molecules in the air with free electrons. Most of the existing air conditioner filter elements use electrostatic adsorption methods, which will eliminate the original negative oxygen ions in the air while removing dust. Therefore, a new type of air conditioner filter element that can improve the filtration efficiency and supplement the negative oxygen ion content of the air entering the air conditioner system is needed. Summary of the Invention

[0003] In order to solve the problems of short contact time between the air flow and the filter screen and poor filtration effect in the existing technology, and the lack of negative oxygen ions in the filtered gas, the purpose of this application is to provide an air conditioner filter element.

[0004] The technical solution adopted by this application is as follows:

[0005] An air conditioner filter element includes a primary filter screen, the primary filter screen is connected to a honeycomb filter screen, a spiral flow guide layer is arranged between the primary filter screen and the honeycomb filter screen, a spiral flow guide device for guiding the air flow direction is arranged on the spiral flow guide layer, the honeycomb filter screen is also connected to an activated carbon filter screen, the activated carbon filter screen is connected to a negative oxygen ion supplement layer, the negative oxygen ion supplement layer includes a coating rope mechanism and a filter paper layer, and the rope part of the coating rope mechanism is attached to the filter paper layer.

[0006] Preferably, the coating rope mechanism includes a plurality of traction wheel groups arranged along the frame, an auxiliary counter wheel is arranged on the other side of the frame, the rope is wound between the traction wheel groups and the auxiliary counter wheel, the traction wheel groups are provided with synchronous wheel teeth, and the frame is also provided with a driving motor, and the traction wheel groups are connected to the driving motor shaft through a synchronous belt.

[0008] Preferably, the honeycomb filter screen has hexagonal mesh filter blades arranged continuously and evenly. The groove port of the spiral flow guide is perpendicular to the mesh filter blades. The air flow guided by the spiral flow guide groove will contact the filter blades at an angle perpendicular to the hexagonal mesh filter blades, reducing the time of flowing directly through the middle gaps of the filter blades and increasing the frequency of contact with the filter blades, thus improving the filtration efficiency.

[0009] Preferably, the frame is provided with a pair of paint storage bins. The rope is arranged in the paint storage bins. The two paint storage bins are connected through a channel. A stirring pump is arranged in the channel. A paint filling port is arranged on one side of the paint storage bin.

[0010] Preferably, the paint in the paint storage bin is a colloidal solvent, and the colloidal solution is mixed with negative oxygen ions, silver ions and spices.

[0011] Preferably, the rope is provided with arc-shaped notches which are arranged evenly on both sides of the rope. The opening side of the arc-shaped notches is attached to the filter paper layer. The end faces of the traction wheel sets and the auxiliary counter wheels wound around both ends of the rope have a certain offset from the filter paper layer, so that the rope is slightly taut and attached to the surface of the filter paper layer, enabling the solvent attached in the arc-shaped notches of the rope to be smeared on the surface of the filter paper layer.

[0012] Preferably, the filter paper layer is laid on the frame to form a closed filter screen. The filter paper layer is provided with dense semi-permeable filter holes. A number of heating wires are laid in the filter paper layer. Electrodes are arranged at the corners of the frame and are electrically connected to the heating wires. The filter paper layer is coated with alumina ceramic. Under the action of the energized electrodes, the heating wires conduct heat to the alumina ceramic coating. The colloidal solvent smeared and attached to the coating by the aforementioned rope coating mechanism is heated and volatilized, and the negative oxygen ions, silver ions, spice molecules, etc. in the solvent are incorporated into the air flow and enter the vehicle.

[0013] Preferably, the primary filter screen and the spiral flow guide layer are docked through the buckles arranged on the edge frame. The edge frame of the spiral flow guide layer is embedded in the square groove formed by the edge frame of the honeycomb filter screen. The honeycomb filter screen and the negative oxygen ion supplementary layer are clamped through the buckles arranged on the edge frame. A number of protrusions with threaded through holes are arranged at the same position on the edges of each of the aforementioned filter screens. Long bolts or ropes are used to connect the threaded through holes in series. To ensure the installation, corresponding structures such as buckles, threaded holes, chutes for fixed connection with the wall of the filter cartridge installation box need to be arranged at the corresponding positions of each layer, which will not be elaborated here.

[0014] The beneficial effects of the present application are as follows: A spiral flow guide layer is added in front of the conventional honeycomb filter screen to increase the contact frequency between the air flow and the main filter screen, improve the filtering effect, and at the end of the filtering structure, a solvent containing negative oxygen ions and spices is continuously drawn and smeared on the filter paper layer. After volatilization, it is mixed into the flowing air and enters the room, increasing the negative oxygen ion content in the indoor air and adding fragrance. BRIEF DESCRIPTION OF THE DRAWINGS

SPECIFIC EMBODIMENTS

[0021] As Figure 1-3 shown, an air conditioner filter element includes a primary filter screen 1, the primary filter screen 1 is connected to a honeycomb filter screen 3, a spiral flow guide layer 2 is arranged between the primary filter screen 1 and the honeycomb filter screen 3, the spiral flow guide layer 2 is provided with a spiral flow guide for guiding the air flow direction, the honeycomb filter screen 3 is also connected to an activated carbon filter screen 4, the activated carbon filter screen 4 is connected to a negative oxygen ion replenishing layer 5, the negative oxygen ion replenishing layer 5 includes a smearing rope mechanism 501 and a filter paper layer 6, and the rope part of the smearing rope mechanism 501 is attached to the filter paper layer 6.

[0022] The coating rope mechanism 501 includes a number of traction wheel sets 502 distributed along the frame. An auxiliary counter wheel 506 is provided on the other side of the frame. The rope is wound between the traction wheel sets 502 and the auxiliary counter wheel 506. The traction wheel sets 502 are provided with synchronous wheel teeth. The frame is also provided with a driving motor 7. The traction wheel sets 502 are connected to the shaft of the driving motor 7 through a synchronous belt 503. The frame is provided with a pair of paint storage bins 504. The rope passes through the paint storage bins 504. The two paint storage bins 504 are connected through a channel. A stirring pump 507 is provided in the channel. A paint filling port 505 is provided on one side of the paint storage bin 504. The paint in the paint storage bin 504 is a colloidal solvent, and the colloidal solution is mixed with negative oxygen ions, silver ions and spices.

[0023] The implementation method is as follows: The driving motor 7 drives the traction wheel sets 502 to rotate through the synchronous belt 503. Each group of traction wheel sets 502 drives the rope to loop and rotate. When the rope passes through the paint storage bin 504, the colloidal solvent fills the arc-shaped notch 5011 and is carried out by the rope, and then applied to the filter paper layer 6.

[0024] As Figure 2 and Figure 5 As shown, a spiral guide layer 2 is provided between the honeycomb filter and the primary filter 1. The spiral guide layer 2 includes a truss 201. The truss 201 is evenly distributed along the border of the spiral guide layer 2. The spiral deflectors 202 are evenly distributed on the truss 201. A spiral groove is provided in the spiral deflector 202. The port of the spiral groove is close to the honeycomb filter 3.

[0025] The honeycomb filter 3 has continuously and evenly distributed hexagonal mesh filter blades. The port of the groove of the spiral deflector 202 is perpendicular to the mesh filter blades. The airflow guided by the groove of the spiral deflector 202 will contact the filter blades at an angle perpendicular to the hexagonal mesh filter blades, reducing the time flowing directly through the middle gaps of the filter blades and increasing the frequency of contact with the filter blades, thereby improving the filtration efficiency.

[0026] As Figure 4 As shown, the rope is provided with arc-shaped notches 5011. The arc-shaped notches 5011 are evenly distributed along both sides of the rope. The opening side of the arc-shaped notch 5011 is attached to the filter paper layer 6. The end faces of the traction wheel sets 502 and the auxiliary counter wheel 506 around which the two ends of the rope are wound have a certain offset from the filter paper layer 6, so that the rope is slightly tightened and attached to the surface of the filter paper layer 6, so that the solvent attached to the arc-shaped notch 5011 of the rope can be applied to the surface of the filter paper layer 6.

[0027] Preferably, the filter paper layer 6 is laid on the frame to form a closed filter screen. The filter paper layer 6 is provided with densely distributed semi-permeable filter holes. A number of heating wires are laid in the filter paper layer 6. Electrodes 601 are provided at the corners of the frame, and the electrodes 601 are electrically connected to the heating wires. The filter paper layer 6 is made of an alumina ceramic coating. Under the action of the energized electrodes 601, the heating wires conduct heat to the alumina ceramic coating, and the colloidal solvent smeared and attached to the coating by the aforementioned smearing rope mechanism 501 is heated and volatilized, and negative oxygen ions, silver ions, spice molecules, etc. in the solvent are incorporated into the air flow and enter the room.

[0028] One implementation is that since the rope is tightly attached to the filter paper layer 6, when it is necessary to increase the mixing amount of silver ions, the heating wire generates heat, and through heat conduction, a part of the colloidal solvent located in the arc-shaped notch 5011 also undergoes thermal volatilization, emitting more beneficial components such as negative oxygen ions.

[0029] As Figure 1 and 2 As shown, the primary filter 1 and the spiral diversion layer 2 are docked through the buckles provided on the edge frame. The edge frame of the spiral diversion layer 2 is embedded in the square groove formed by the edge frame of the honeycomb filter 3. The honeycomb filter 3 and the negative oxygen ion supplement layer 5 are snap-connected through the buckles provided on the edge frame. A number of protrusions with threaded through holes are provided at the same position on the edges of the foregoing filters. Long bolts or ropes are used to connect the threaded through holes. To ensure the installation, corresponding structures such as buckles, threaded holes, chutes, and other corresponding structures for fixed connection with the wall of the filter installation box need to be provided at the corresponding positions of each layer, which will not be elaborated here.
