Description

Technical Field

[0001] This invention relates to the field of air purification technology, and more particularly to ion filters and transportation devices. Background Technology

[0002] Air conditioning is typically installed in vehicles and other transportation devices to improve air quality. Substances contributing to poor air quality include particulate matter of various diameters, with fine particles (0.1μm-0.5μm) usually filtered using electrostatic adsorption. However, with the use of air conditioning filters, the electrostatic adsorption capacity of the filter fibers is largely neutralized by particulate matter, significantly reducing filtration efficiency for fine particles. Furthermore, as dust and debris accumulate on the filter, bacteria and mold can proliferate in hot and humid environments, producing unpleasant odors and harming respiratory health.

[0003] To address the aforementioned issues, some existing air conditioners are equipped with negative ion filters at their air intake. These filters primarily consist of a negative ion generator and a filter screen. The negative ions generated by the generator cause airborne particles to become negatively charged, while the grounded filter screen remains positively charged. The negatively charged particles are then adsorbed onto the filter screen, significantly reducing the amount of particulate matter reaching the air conditioner.

[0004] The defects of existing negative ion filter products include: poor grounding performance of the filter screen and unreasonable arrangement, resulting in weak adsorption capacity for negatively charged particles; and inability to determine whether the filter screen is installed properly and grounded well. Summary of the Invention

[0009] In one preferred embodiment, the frame assembly includes a pressing strip with elastic legs formed thereon, the elastic legs abutting against the grounding clamp, and the activated carbon filter element is grounded through the grounding clamp, the pressing strip, and the frame assembly.

[0010] In one preferred embodiment, the ion filter further includes a controller grounding wire, a terminal, and a detection spring made of metal connected in sequence. The detection spring is in contact with the activated carbon filter element through a grounding clamp. When the grounding state of the activated carbon filter element meets the requirements, the voltage value on the activated carbon filter element is within a set range. When the grounding state of the activated carbon filter element does not meet the requirements, the activated carbon filter element is negatively charged.

[0011] In one preferred embodiment, the detection spring includes a first step, a second step, and a connecting part connected in sequence. The first step abuts against the grounding conductor clamp, and the connecting part has a connecting notch, with the terminal inserted into the connecting notch.

[0012] In one preferred embodiment, the frame assembly further includes a mounting frame with a stepped portion formed on the inner wall of the mounting frame, the stepped portion dividing the interior of the mounting frame into a first region and a second region, the negative ion generator being located in one of the first region and the second region, and the activated carbon filter being located in the other of the first region and the second region, wherein the negative ion generator and the activated carbon filter can be detached from the mounting frame respectively.

[0013] In one preferred embodiment, the ion filter further includes a first base and a second base, which are interlocked to form a space for installing the negative ion generator. The first base has a first base through hole, through which the tip of the negative ion generator extends. The second base abuts against the stepped portion.

[0014] In one preferred embodiment, all the activated carbon filter elements are divided into at least two filtration zones, and a negative ion generator is provided at the center of each filtration zone. The negative ions emitted by one negative ion generator can cover the filtration zone in which it is located.

[0015] In one preferred embodiment, the frame assembly includes a retaining strip and a mounting frame; the retaining strip is connected to an elastic support and a detection spring made of metal; the ion filter further includes a first base with two through holes respectively aligned with the elastic support and the detection spring; the ion filter further includes two connecting springs, each of which includes a first connecting spring portion and a second connecting spring portion connected to each other; the mounting frame has a first window and a second window formed therein, the first connecting spring portion being embedded in one of the first window and the second window, and the second connecting spring portion being embedded in the other of the first window and the second window; the first connecting spring portion has a hole and a first elastic snap-fit ​​is formed in the hole, and the second connecting spring portion has a hole and a second elastic snap-fit ​​is formed in the hole.

[0018] This invention relates to an ion filter comprising a negative ion generator and an activated carbon filter. The ion generator imparts a negative charge to airborne particulate matter, while the activated carbon filter, being positively charged relative to the negatively charged particles, adsorbs them, preventing these fine particles from reaching the air conditioner and improving overall air filtration efficiency. The negative ions generated by the negative ion generator continuously replenish the static electricity of the activated carbon filter, preventing static electricity decay with use and enhancing its adsorption capacity for particulate matter. Furthermore, the negative ions inhibit bacterial and odor growth on the activated carbon filter, resulting in a better user experience.

[0019] The transportation device of the present invention includes the aforementioned ion filter. The activated carbon filter element prevents negatively charged fine particles from reaching the air conditioner, pre-filters the air, improves the overall air filtration effect, and provides a better user experience.

[0051] Example 1

[0052] This embodiment discloses an ion filter and a transportation device including the ion filter. The transportation device can be, but is not limited to, vehicles, airplanes, ships, etc. Specifically, the transportation device also includes an air conditioner, with the ion filter located at the air inlet of the air conditioner. The ion filter can intercept fine particulate matter in the air, achieving preliminary filtration of the air entering the passenger compartment of the transportation device, resulting in higher air quality in the passenger compartment and a longer service life for the air conditioner.

[0053] like Figures 1 to 4 As shown, the ion filter includes a frame assembly 1, a negative ion generator 2, at least two rows of activated carbon filter elements 3, and a high-voltage module 9. The high-voltage module 9 is connected to the negative ion generator 2. The negative ion generator 2 emits negative ions to negatively charge particulate matter in the air. The frame assembly 1 is grounded, and the activated carbon filter elements 3 are grounded through the frame assembly 1. The specific location of the high-voltage module 9 is not limited; in this embodiment, the high-voltage module 9 is fixed to the air conditioning unit.

[0054] The activated carbon filter element 3 is positively charged relative to negatively charged particles, enabling it to adsorb these particles. Fine particles, especially those with a diameter in the range of 0.1μm-0.5μm, are more easily adsorbed by the electric field force, preventing them from reaching the air conditioner and improving overall air filtration efficiency. The negative ions generated by the negative ion generator 2 continuously replenish the static electricity of the activated carbon filter element 3, preventing static electricity decay with use and enhancing its adsorption capacity for particles. Additionally, the negative ions inhibit the growth of bacteria and odors on the activated carbon filter element 3, resulting in a better user experience.

[0055] The specific structure and arrangement of the activated carbon filter element 3 are not limited, as long as the good conductivity of activated carbon can be used to ground and conduct. In this embodiment, the activated carbon filter element 3 includes a shell and activated carbon filled in the shell. The activated carbon can make the shell also be in a positive state, and negatively charged particles are more easily adsorbed on the activated carbon filter element 3.

[0056] The ion filter includes multiple activated carbon filter elements 3 arranged in rows. All the activated carbon filter elements 3 form a grid shape, which can effectively intercept negatively charged particles. It has a stronger adsorption capacity for negatively charged particles and a better pre-filtration effect on the air.

[0057] To ensure that all particulate matter in the air being filtered has the opportunity to acquire a negative charge, in this embodiment, all activated carbon filter elements 3 are divided into at least two filtration zones. A negative ion generator 2 is positioned at the center of each filtration zone, facing the direction of the incoming airflow. The negative ions emitted by one negative ion generator 2 can cover the filtration zone it occupies. The specific shape of the filtration zone is not limited, but square is preferred. The distance between the negative ion generator 2 and the four corners of the filtration zone is equal, resulting in a more uniform and symmetrical distribution of negative ions within the filtration zone.

[0058] The specific material used to manufacture the negative ion emitting end of the negative ion generator 2 is not limited. In this embodiment, the negative ion emitting end is a pointed emitting electrode made of steel needle or carbon fiber. The frame assembly 1 includes a metal sheet surrounding the negative ion generator 2, enabling the negative ion generator 2 to be grounded and conductive.

[0059] After being powered on, the negative ion generator 2 generates a large number of negative ions through the conversion of the high-voltage module 9. A uniform electric field is formed between the negative ions and the frame component 1, which is positively charged. After being ejected, the negative ions disperse and migrate to the surrounding frame components 1 under the influence of the electric field, resulting in a large number of negative ions evenly distributed in each filtration area. Particles become negatively charged as they pass through this filtration area. When small, negatively charged particles pass through the relatively positively charged activated carbon filter element 3, the activated carbon filter element 3 adsorbs the negatively charged particles through the electric field.

[0060] The specific conductive connection structure between the activated carbon filter element 3 and the frame assembly 1 is not limited. In this embodiment, for example... Figure 1 , Figure 2 and Figure 5 As shown, the ion filter also includes a grounding clamp 4 made of metal. The grounding clamp 4 includes an inverted U-shaped clamp body 41, with a clamp cavity 42 formed in the middle of the clamp body 41 for inserting the activated carbon filter element 3. The clamp body 41 is provided with a piercing part 43 extending toward the clamp cavity 42. After assembly, the piercing part 43 at least partially penetrates the activated carbon filter element 3, realizing the circuit connection between the grounding clamp 4 and the activated carbon filter element 3.

[0061] The specific conductive connection structure between the grounding clamp 4 and the frame assembly 1 is not limited. In this embodiment, for example... Figure 6 and Figure 7 As shown, the frame assembly 1 includes a pressing strip 11, on which elastic legs 111 with a certain degree of elastic deformation are formed. The bottom surface of the elastic legs 111 is higher than the top surface of the grounding clamp 4. After assembly, the elastic legs 111 abut against the grounding clamp 4, and the activated carbon filter element 3 is grounded through the grounding clamp 4, the pressing strip 11, and the frame assembly 1.

[0062] Based on the above structure, such as Figure 1, Figure 2 and Figure 8 As shown, the ion filter also includes a controller grounding wire 5, a terminal 6, and a metal detection spring 7 connected in sequence. The detection spring 7 is in contact with the activated carbon filter element 3 via a grounding clamp 4. This detection spring 7 is used to detect whether the activated carbon filter element 3 is properly grounded. After assembly, the detection spring 7 is not conductive to the corresponding edge strip 11. It should be noted that the edge strip 11 corresponding to the detection spring 7 is not an edge strip 11 with elastic support legs 111; the two edge strips 11 are respectively located on different sides of the activated carbon filter element 3.

[0063] The grounding contact clip 4, which abuts against the detection spring 7, and the grounding contact clip 4, which abuts against the elastic support foot 111, are respectively located at two opposite corners of the activated carbon filter element 3. This layout is more reasonable and avoids mutual interference between the detection spring 7 and the elastic support foot 111. It is understood that the terminal 6 can be, but is not limited to, a spring-loaded terminal. The spring-loaded terminal can be, but is not limited to, riveted to the controller grounding wire 5, resulting in a more stable connection structure and higher measurement accuracy.

[0064] The controller grounding wire 5 is connected to the grounding detection circuit of the high voltage module 9. When the grounding status of the activated carbon filter element 3 meets the requirements (good grounding), the voltage value on the activated carbon filter element 3 is within the set range, and the controller grounding wire 5 can hardly detect the voltage.

[0065] When the grounding status of activated carbon filter element 3 is not met (not grounded), the negative ions generated by negative ion generator 2 cannot be adsorbed and guided by activated carbon filter element 3. At this time, activated carbon filter element 3 is in a negatively charged state, and the controller grounding wire 5 can detect the negative voltage. The grounding detection circuit of high voltage module 9 will send a signal to the control device, indicating that activated carbon filter element 3 is not grounded. It is necessary to check whether activated carbon filter element 3 is installed in place, whether the grounding conductor clip 4 and the pressure strip 11 with elastic support foot 111 are missing, and whether the conductor clip 4 and the pressure strip 11 with elastic support foot 111 are oxidized.

[0066] The specific structure of the grounding detection circuit in the high-voltage module 9 is not limited, and any existing device that can detect whether the grounding status of the activated carbon filter element 3 meets the requirements can be used.

[0067] The specific structure of the detection spring 7 is not limited; in this embodiment, for example... Figure 8 and Figure 9As shown, the detection spring 7 includes a first step 71, a second step 72, and a connecting part 73 connected in sequence. The first step 71 abuts against the grounding conductor clamp 4 to ensure that the detection spring 7 is in full contact with the grounding conductor clamp 4. The pressure strip 11 of the frame assembly 1 is located above the second step 72, but the pressure strip 11 does not contact or conduct with the detection spring 7. A connecting notch 74 is provided on the connecting part 73, and the terminal 6 is locked in the connecting notch 74 to enhance the stability of the connection between the terminal 6 and the detection spring 7. Even if there is vibration, the terminal 6 will not be separated from the detection spring 7, and the detection accuracy is high.

[0068] Based on the above structure, such as Figure 1 and Figure 10 As shown, the frame assembly 1 also includes a mounting frame 12, which includes four sides forming a rectangle, an opening on the top surface, and a hollowed-out bottom surface 123. This design prevents the activated carbon filter element 3 from coming out of the mounting frame 12 while providing good gas flow. After negatively charged particles are intercepted by the activated carbon filter element 3, clean air can flow out after passing through the hollowed-out parts of the activated carbon filter element 3 and the bottom surface 123 of the frame.

[0069] Stepped sections 121 are formed on the inner walls of the four sides of the mounting frame 12, forming a U-shape. The stepped sections 121 divide the interior of the mounting frame 12 into a first region and a second region. Specifically, the area from the top opening to the stepped sections 121 is the first region, and the area from the stepped sections 121 to the bottom surface 123 of the frame is the second region. The negative ion generator 2 is located in one of the first and second regions, and the activated carbon filter 3 is located in the other of the first and second regions. In this embodiment, the negative ion generator 2 is located in the first region, and the activated carbon filter 3 is located in the second region.

[0070] The negative ion generator 2 and the activated carbon filter 3 can be disassembled from the mounting frame 12 separately, facilitating individual maintenance and replacement without interference. This eliminates the need to remove both the negative ion generator 2 and the activated carbon filter 3, making them more convenient to use. The specific disassembly and assembly methods for the negative ion generator 2 and the activated carbon filter 3 are not limited. In this embodiment, when the negative ion generator 2 malfunctions and requires maintenance or replacement, the high-voltage module 9 can be removed, and the mounting frame 12 can be pulled out of the outer frame 14 of the frame assembly 1 to maintain or replace the negative ion generator 2. The assembly can then be completed by reassembling the negative ion generator 2.

[0071] The outer frame 14 serves to enclose the negative ion generator 2 and activated carbon filter 3, etc., together. The shape of the outer frame 14 should match the structure it encloses. In this embodiment, for example... Figure 14 and Figure 15As shown, the outer frame 14 is a rectangular cube. Its top, bottom, and one side for assembling and disassembling the negative ion generator 2 and the activated carbon filter 3 are hollowed out, while the other three sides are provided with side plates. Outer frame baffles 141 are formed at the junction of the top and side surfaces and at the junction of the bottom and side surfaces, respectively, to prevent the internal structure from coming out through the hollowed-out top or bottom surfaces, making it safer and more reliable to use.

[0072] To ensure more stable installation of the negative ion generator 2 in the first area, at least two limiting buckles 124 are provided on the inner side wall of the mounting frame 12. During assembly, the negative ion generator 2 and its mounting base are pressed downwards together, causing the limiting buckles 124 to elastically deform and avoid obstructing the downward pressure of the negative ion generator 2 and its mounting base. When the mounting base of the negative ion generator 2 abuts against the step portion 121, the limiting buckles 124 spring back and abut against the mounting base from above, forming an integral structure of the ion generator 2, the mounting base, and the mounting frame 12.

[0073] The specific structure of the mounting base is not limited, as long as it can provide stable support for the negative ion generator 2. In this embodiment, for example... Figure 1 , Figure 11 and Figure 12 As shown, the mounting base includes a first base 81 and a second base 82 that can be fastened together by base clips 84. After the first base 81 and the second base 82 are fastened together, they form multiple spaces for mounting the negative ion generator 2. Specifically, the first base 81 has a first base through hole 83 through which the tip of the negative ion generator 2 protrudes, generating and spraying negative ions in the direction of the incoming airflow. The second base 82 supports the negative ion generator 2 from below, preventing it from detaching from the mounting base. After assembly, the second base 82 abuts against the stepped portion 121, preventing the negative ion generator 2 from entering the second area from the first area.

[0074] The specific fastening structure between the first base 81 and the second base 82 is not limited. In this embodiment, one of the first base 81 and the second base 82 is provided with seven limiting hooks, and the other of the first base 81 and the second base 82 or the corresponding position on the negative ion generator 2 is designed with seven limiting slots. After assembly, the limiting hooks are inserted into the limiting slots to achieve the snap-fit ​​between the first base 81 and the second base 82, limiting the deformation of the combined structure of the first base 81 and the second base 82, and making the product dimension more stable.

[0075] To facilitate the disassembly and assembly of the activated carbon filter element 3, in this embodiment, as follows: Figure 10 , Figure 13 and Figure 14As shown, a filter element through-hole 122 is provided on the side of the mounting frame 12, and a removable frame cover plate 13 is installed on the filter element through-hole 122. The specific location of the filter element through-hole 122 on the mounting frame 12 is not limited, as long as it facilitates the installation and removal of the activated carbon filter element 3. When it is necessary to install or remove the activated carbon filter element 3, the frame cover plate 13 is removed from the mounting frame 12, which exposes the filter element through-hole 122, allowing the activated carbon filter element 3 to enter and exit the second area through the filter element through-hole 122.

[0076] Example 2

[0077] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the activated carbon filter element and the negative ion generator are grounded and connected, and the detection is also connected. The specific structure is as follows.

[0078] like Figures 16 to 18 , Figure 21 and Figure 23 As shown, the edge strip 11 is connected to an elastic support leg 111 and a detection spring 7 made of metal. Both the elastic support leg 111 and the detection spring 7 are grounding electrode plates of the negative ion generator 2. The first base 81 has two through holes that are respectively aligned with the elastic support leg 111 and the detection spring 7. After assembly, the elastic support leg 111 and the detection spring 7 can be seen and contacted through the through holes on the first base 81. That is, the elastic support leg 111 and the detection spring 7 form an exposed metal contact surface.

[0079] The ion filter also includes two connecting springs 15, such as Figure 20 As shown, each connecting spring 15 includes a first connecting spring portion 151 and a second connecting spring portion 152 connected to each other; the first connecting spring portion 151 has an opening and a first elastic snap-fit ​​piece 154 is formed in the opening, and the second connecting spring portion 152 has an opening and a second elastic snap-fit ​​piece 155 is formed in the opening.

[0080] like Figure 19 and Figure 20 As shown, the mounting frame 12 has a first opening 125 and a second opening 126. After assembly, the first connecting spring portion 151 is embedded in one of the first opening 125 and the second opening 126, and the second connecting spring portion 152 is embedded in the other of the first opening 125 and the second opening 126. The first connecting spring portion 151 and the second connecting spring portion 152 are respectively provided with heat-fusion through holes 153, and the mounting frame 12 is provided with heat-fusion pillars 127, which pass through the heat-fusion through holes 153. After the heat-fusion pillars 127 melt and deform, the connecting spring 15 is firmly fixed to the mounting frame 12.

[0081] The specific structure for grounding and conducting of the activated carbon filter element 3 is not limited. In this embodiment, the frame assembly 1 includes a filter element frame 31, which wraps around the outer periphery of the activated carbon filter element 3. The filter element frame 31 can be made of graphite or have graphite added to it. Alternatively, graphite can be filled between the contact surfaces of the activated carbon filter element 3 and the filter element frame 31, so that the activated carbon filter element 3 can be grounded and conducted through the filter element frame 31.

[0082] The ion filter includes two connecting springs 15 made of metal. In one of the connecting springs 15, one of the first elastic snap-fit ​​piece 154 and the second elastic snap-fit ​​piece 155 abuts against the elastic support foot 111 through a through hole on the first base 81, and the other is connected to the filter element frame 31, thereby connecting the elastic support foot 111 to the filter element frame 31. The first elastic snap-fit ​​piece 154, the second elastic snap-fit ​​piece 155, and the elastic support foot 111 all have elastic deformation capability and conductivity, which does not affect the replacement and installation of the negative ion generator 2 and the activated carbon filter element 3, and at the same time can ground the filter element frame 31, thereby grounding the activated carbon filter element 3.

[0083] In another connecting spring 15, one of the first elastic snap-fit ​​piece 154 and the second elastic snap-fit ​​piece 155 abuts against the detection spring 7 through a through hole on the first base 81, while the other is connected to the filter element frame 31, thereby connecting the detection spring 7 to the filter element frame 31. The function of this connecting spring 15 is to detect whether the activated carbon filter element 3 is grounded. Figure 22 and Figure 23 As shown, the detection spring 7 includes a first step 71 and a connecting part 73 connected to each other. A connecting notch 74 is provided on the connecting part 73. The terminal 6 is inserted into the connecting notch 74. The terminal 6 is connected to the grounding detection circuit in the high voltage module 9 through the controller grounding wire 5.

[0084] When the activated carbon filter element 3 is properly grounded, the controller grounding wire 5 will detect almost no voltage. When the activated carbon filter element 3 is poorly grounded, because the negative ions (presenting a negative charge) generated by the negative ion generator 2 act on the activated carbon filter element 3, and the activated carbon filter element 3 is not grounded, the negative charge cannot be adsorbed and conducted, resulting in the interlayer (filter element frame 31) of the activated carbon filter element 3 being in a negatively charged state. Therefore, the controller grounding wire 5 can detect a negative voltage. The detection signal is fed back to the high-voltage module 9, indicating that the activated carbon filter element 3 is not grounded. At this time, it is necessary to check whether the activated carbon filter element 3 is installed properly, whether the metal clip is missing, or whether the metal parts are oxidized, etc., to ensure the functional integrity of the ion filter.

[0085] In this embodiment, the ion filter can filter the air that is about to enter the passenger cabin, resulting in a better user experience; negative ions can continuously replenish the static electricity of the activated carbon filter element 3 and will not decrease with the use of the activated carbon filter element 3.
