Description

Technical Field

[0001] The utility model relates to the technical field of filter screens, and in particular to an air filtering device and purification equipment. Background Art

[0002] In the field of air purification devices, electrostatic dust removal is a method of gas dust removal. Its principle is: dust-containing gas is electrically separated when passing through a high-voltage electrostatic field, and dust particles are combined with negative ions to carry negative charges, and then discharge toward the anode surface and deposit. That is, in a strong electric field, air molecules are ionized into positive ions and electrons, and electrons encounter dust particles when rushing to the positive electrode, causing the dust particles to be negatively charged and adsorbed to the positive electrode and collected.

[0003] refer to Figure 1 As shown in Chinese patent CN213943527U, it is an electrostatic precipitator known in the related art. The electrostatic precipitator is a cylindrical structure, in which adjacent high and low potential electrodes are set at a distance. The distance has requirements. If the distance is too large, the electric field voltage between the electrodes will be insufficient, making it difficult to effectively ionize the air molecules into positive ions and negative ions. Of course, this can be overcome by increasing the voltage, but this will consume more electricity and have higher performance requirements on electrical components.

[0004] Therefore, in the electrostatic precipitator devices currently on the market, the distance between the potential electrodes is usually narrow. When users clean them, it is difficult to deeply clean the interior between the electrodes. Over time, dust will accumulate in the difficult-to-clean areas on the electrode sheets, thereby affecting the air purification efficiency of the electrostatic precipitator. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The specific structure of an air filter device provided by an embodiment of the utility model and the corresponding technical effects it brings are described in detail below in conjunction with the patent drawings.

[0046] It should be noted that the air filter device provided in this embodiment is an electrostatic dust removal filter device, which mainly forms an electrostatic field between a high-potential plate and a low-potential plate to dissociate the air and generate positive and negative ions. The positive ions are charged after contacting the dust particles, and the air molecules are ionized into positive ions and electrons. The electrons encounter dust particles when rushing to the positive electrode, causing the dust particles to be negatively charged and adsorbed to the positive electrode and collected. First, please refer to Figure 2 An air filter device 1 provided in an embodiment of the utility model includes a first plate unit 100 and a second plate unit 200 which can be detached from each other.

[0047] Combined with reference Figures 2 to 4The first electrode unit 100 is generally cylindrical, including an assembly shell 110, a first mounting column 120, and a plurality of first electrode plates 130 spaced apart along the extending direction of the first mounting column 120. The first mounting column 120 is disposed on the assembly shell 110. Specifically, in this embodiment, the end of the first mounting column 120 is disposed on the assembly shell 110, and the first mounting column 120 extends along the first direction. The first direction is a direction parallel to the axis of the first electrode unit 100 (e.g., Figure 2 The middle part is extended in the up and down directions).

[0048] The second plate unit 200 includes a plurality of second sub-plate units 210 (for example, two in the present embodiment), the second sub-plate units 210 are sequentially connected end to end to form a ring-shaped second plate unit 200, two adjacent second sub-plate units 210 are detachably connected, and the second sub-plate unit 210 includes a plurality of second plates 211 arranged at intervals along the first direction.

[0049] When the first electrode plate unit 100 and the second electrode plate unit 200 are in the assembled state, the first electrode plate 130 and the two adjacent second electrode plates 211 are alternately arranged, that is, there is a first electrode plate 130 between two adjacent second electrode plates 211, and similarly, there is a second electrode plate 211 between two adjacent first electrode plates 130, and the second sub-electrode plate unit 210 is detachably connected to the first electrode plate unit 100.

[0050] One of the first electrode plate 130 and the second electrode plate 211 is a high potential electrode plate, and the other is a low potential electrode plate. For example, in this embodiment, the first electrode plate 130 is a high potential electrode plate, and the second electrode plate 211 is a low potential electrode plate.

[0051] The high potential plate is also called the anode or positive plate, which is the side to which a high voltage is applied. When the electrostatic dust collector is in operation, the high potential plate is usually connected to the positive pole of the power supply, receiving a DC high voltage charge of thousands of volts or even tens of thousands of volts. This high potential forms a strong electric field near the high potential plate, which can attract and charge dust particles in the air. Its main function is to generate a strong electric field so that dust particles in the air passing through the air filter device 1 gain an electric charge. When charged particles pass near the high potential plate, due to the Coulomb force, negatively charged particles will be attracted by the positive pole, while positively charged particles will be repelled. In this way, the dust particles are accelerated and directed under the action of the electric field force, and are eventually adsorbed onto the plate with an opposite charge to their own, thereby achieving effective capture of dust.

[0052] The low potential plate is also called the cathode or negative plate or grounded plate, and its potential is set to a low voltage, ground potential or close to ground potential (zero potential). In practical applications, the low potential plate is usually directly grounded or grounded through the negative pole of the power supply to ensure that its potential is consistent with the ambient earth. The low potential plate acts as a relatively low potential reference point in the electrostatic field, providing a loop for the electric field generated by the high potential plate.

[0053] In this embodiment, the second plate unit 200 is a low potential plate unit, that is, the second plate 211 in the second sub-plate unit 210 is a low potential plate. Of course, in some other embodiments, the first plate unit 100 can also be a low potential plate unit, that is, the first plate 130 is a low potential plate.

[0054] In some existing air filtering devices 1, in order to ensure the electrostatic dust collection effect, the distance between the low potential plate in the low potential plate unit and the high potential plate in the high potential plate unit is small, making it difficult for users to clean the low potential plate and the high potential plate.

[0055] Since the second plate unit 200 in this embodiment is composed of a plurality of second sub-plate units 210 which are sequentially detachable and connected end to end, and the second sub-plate unit 210 is also detachably connected to the first plate unit 100, when the user needs to clean the plates in the air filter device 1, the second sub-plate unit 210 can be separated, and the second sub-plate unit 210 can be separated from the first plate unit 100. At this time, for the first plate unit 100, no second plate 211 is provided between any two adjacent first plates 130 in the first plate unit 100. Therefore, at this time, the spacing between adjacent first pole plates 130 is larger than the spacing between adjacent first pole plates 130 and second pole plates 211 when they are not split, so it is convenient for users to clean the first pole plates 130. Similarly, for the second sub-plate unit 210, no first pole plate 130 is set between any two adjacent second pole plates 211 in the second sub-plate unit 210. At this time, there is a larger gap between adjacent second pole plates 211, which can facilitate users to clean the second pole plates 211, thereby preventing the accumulation of dust from reducing the air filtration efficiency.

[0056] In detail, in the present embodiment, the number of second sub-plate units 210 is two, the second plate 211 in each second sub-plate unit 210 is roughly semicircular, the first plate 130 in the first plate unit 100 is roughly circular, and the number of assembly shells 110 in the first plate unit 100 is two, the two assembly shells 110 are also arranged at intervals along the first direction, and the two ends of the first mounting column 120 are respectively connected to the two assembly shells 110, and the two ends of the first mounting shell 213 are respectively abutted against the two assembly shells 110, and the two ends of the second mounting shell 214 are also respectively abutted against the two assembly shells 110, that is, the second sub-plate unit 210 is arranged between the two assembly shells 110, and the two assembly shells 110 can limit the movement of the second sub-plate unit 210 in the first direction.

[0057] When the second electrode plate unit 200 is assembled to the first electrode plate unit 100, the second electrode plate unit 200 is completely embedded in the first electrode plate unit 100. Specifically, the inner circumferential surface of the first electrode plate 130 and the inner circumferential surface of the second electrode plate 211 are on the same cylindrical surface, and the outer circumferential surface of the first electrode plate 130 and the outer circumferential surface of the second electrode plate 211 are on the same cylindrical surface.

[0058] Below, combined with reference Figure 3 and Figure 7 For explanation, optionally, the second sub-plate unit 210 is provided with a first mounting shell 213 and a second mounting shell 214 on both sides in the second direction, and the second direction is at an angle to the first direction. Specifically, in this embodiment, the second direction is perpendicular to the first direction, that is, the second direction is perpendicular to the axial direction, and the two sides mentioned here refer to the two sides of the second sub-plate unit 210 in the direction perpendicular to the axial direction. On the other hand, the two ends of the second plate 211 are respectively connected to the first mounting shell 213 and the second mounting shell 214, and the two ends mentioned here refer to the two ends perpendicular to the axial direction. The first mounting shell 213 and the second mounting shell 214 are configured as strips for connecting to a plurality of second plates 211 spaced apart along the first direction. A first clamping member 2132 is provided on the first mounting shell 213, and a second clamping member 2141 is provided on the second mounting shell 214. One side of the second sub-plate unit 210 is clamped with the second clamping member 2141 of the adjacent second sub-plate unit 210 through the first clamping member 2132. The first mounting shell 213 and the second mounting shell 214 are installed on the assembly shell 110.

[0059] Optionally, a first clamping member 2132 is provided at a middle portion of the first installation shell 213 in its own extension direction, and a second clamping member 2141 is provided at a middle portion of the second installation shell 214 in its own extension direction.

[0060] Optionally, refer to Figure 7-Figure 9In the present embodiment, the first clamping member 2132 is a clamping slider, which can slide relative to the first mounting shell 213, and the clamping slider is provided with a buckle, and the second clamping member 2141 is a clamping hole, and the clamping hole has an unlocking position 2143 and a locking position 2142, and the buckle can slide between the unlocking position 2143 and the locking position 2142 of the clamping hole, and when the buckle slides to the unlocking position 2143, the first clamping member 2132 and the second clamping member 2141 are unlocked, and when the buckle slides to the unlocking position 2143, the first clamping member 2132 and the second clamping member 2141 are locked, and at this time, the adjacent second sub-plates are connected.

[0061] In detail, the locking slider can slide relative to the first mounting shell 213 along the extension direction of the first mounting shell 213. In order to prevent the first locking member 2132 from sliding beyond the limit on the first mounting shell 213, a sliding groove 2131 is further provided on the first mounting shell 213, and the sliding groove 2131 extends along the extension direction of the first mounting shell 213. It can be understood that the sliding groove 2131 is respectively provided with a first stop wall and a second stop wall in the extension direction of the first mounting shell 213. The first stop wall and the second stop wall can prevent the locking slider from sliding beyond the limit, thereby ensuring that the locking slider slides into place. That is to say, when the first locking member 2132 slides to the first stop wall, the buckle is in the unlocking position 2143 of the locking hole, and when the first locking member 2132 slides to the other second stop wall, the buckle is in the locking position 2142 of the locking hole.

[0062] Optionally, in some other embodiments, the first clamping member 2132 and the second clamping member 2141 can also be a plug-in structure, that is, the plug-in of the first clamping member 2132 and the second clamping member 2141 is completed, and the plug-in of the first mounting shell 213 and the second mounting shell 214 in the adjacent second sub-plate unit 210 is completed. When the number of second sub-plate units 210 in the second plate unit 200 is two, the two sides of the two second sub-plate units 210 are respectively plugged in by the first clamping member 2132 and the second clamping member 2141 to realize the plug-in connection of the annular second plate unit 200.

[0063] Optionally, the first clamping member 2132 and the second clamping member 2141 may also be other types of clamping structures, as long as the clamping fit between the first mounting shell 213 and the second mounting shell 214 can be achieved.

[0064] Of course, in some other embodiments, the first mounting shell 213 may also be detachably connected via threaded fasteners.

[0065] Optionally, the first mounting shell 213 is provided with a first connecting member 2133, and the second mounting shell 214 is provided with a second connecting member 2144. For the adjacent second sub-plate unit 210, the first connecting member 2133 of the first mounting shell 213 and the second connecting member 2144 in the adjacent second mounting shell 214 are detachably connected.

[0066] In detail, both ends of the first installation shell 213 in the first direction are provided with first connecting members 2133 , and both ends of the second installation shell in the first direction are provided with second connecting members 2144 .

[0067] That is to say, by providing the first connecting members 2133 at both ends of the first mounting shell 213 and the second connecting members 2144 at both ends of the second mounting shell 214, the assembly of the first connecting members 2133 and the second connecting members 2144 at both ends can ensure that there is a smaller gap between the two ends of the first mounting shell 213 and the second mounting shell 214, and ensure that the first mounting shell 213 and the second mounting shell 214 of the two adjacent second sub-plate units 210 have a smaller assembly gap, thereby ensuring beauty.

[0068] Optionally, in this embodiment, the first connecting member 2133 and the second connecting member 2144 are magnetically connected, and at least one of the first connecting member 2133 and the second connecting member 2144 is a magnet.

[0069] Please refer to Figure 5-Figure 6 Similarly, the second sub-plate unit 210 also includes a second mounting column 212, which is parallel to the first mounting column 120, and a plurality of second plates 211 are arranged at intervals along the extension direction of the second mounting column 212, and the extension direction of the second mounting column 212 is the first direction. The second mounting column 212 is located between the first mounting shell 213 and the second mounting shell 214, and a plurality of clearance openings 131 are provided on the periphery of each first plate 130, and the number of the clearance openings 131 on each first plate 130 is the same as the number of the second mounting columns 212, and the second mounting columns 212 are located in the clearance openings 131.

[0070] Understandable, please continue to refer to Figure 5-Figure 6 The multiple clearance openings 131 of the multiple first pole plates 130 together form a plurality of clearance grooves for installing the second mounting column 212. It can be understood that the multiple clearance grooves are arranged at intervals around the circumference of the first pole plate unit 100. That is to say, through the cooperation between the clearance grooves and the second mounting column 212, the second sub-plate unit 210 can be restricted from moving in the radial direction of the first pole plate unit 100, thereby ensuring that the second sub-plate unit 210 is installed in place.

[0071] The first electrode unit 100 also includes a first conductive chain 150 and an insulating protective shell 140. The insulating protective shell 140 has a first installation cavity 141 for installing the first conductive chain 150. The first installation cavity 141 faces the first electrode 130. The first conductive chain 150 is connected to multiple first electrode plates 130. It is easy to understand that the first conductive chain 150 is used to supply power to the first electrode 130, and the insulating protective shell 140 can prevent the first conductive chain 150 from being exposed.

[0072] The insulating protective shell 140 is installed on the assembly shell 110 . Specifically, two ends of the insulating protective shell 140 abut against the two assembly shells 110 .

[0073] The second sub-plate unit 210 also includes a second conductive chain 215. The first mounting shell 213 and the second mounting shell 214 both have a second mounting cavity 2145 for mounting the second conductive chain 215. The second mounting cavity 2145 faces the second plate 211. The second conductive chain 215 is connected to a plurality of second plates 211. The first mounting shell 213 and the second mounting shell 214 are both made of insulating material. The first mounting shell 213 and the second mounting shell 214 can effectively prevent the second conductive chain 215 from being exposed.

[0074] It should be noted that, in this embodiment, the plurality of first plates 130 are all mounted on the cylindrical first mounting post 120 , and for a second sub-plate unit 210 , the plurality of second plates 211 are also mounted on the cylindrical second mounting post 212 .

[0075] Of course, in some other embodiments, the first mounting column 120 and the second mounting column 212 may also be in other shapes, such as a rectangular parallelepiped.

[0076] The utility model embodiment also provides a purification device, including the above-mentioned air filter device 1. The purification device includes but is not limited to an air purifier. It can be understood that the purification device also has the beneficial effects of the above-mentioned filter device 1, so the technical effects brought by the purification device are not repeated here.

[0077] In summary, the embodiment of the utility model provides an air filter device 1 and a purification device, the purification device comprising an air filter device 1, the air filter device 1 comprising a first electrode unit 100 and a second electrode unit 200 which can be detachably mounted on each other.
