Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and in particular to a highly reliable and infinitely splicable air purification device. Background Art

[0002] As air quality has received increasing attention, air purification devices have been widely used in various fields. Among them, electrostatic technology has become one of the mainstream technologies in the field of air purification due to its high efficiency and low energy consumption. Electrostatic air purification devices mainly achieve air purification through ionization areas and dust collection areas. The ionization area generates charged particles by high-voltage ionization of air, while the dust collection area adsorbs the charged particles on the dust collection plate through the action of the electric field, thereby achieving the purpose of purifying the air.

[0003] However, the electrical box of a traditional air purification device usually adopts an external design, and the electrical box is set above the frame for accommodating the dust collection module and the field electric module. This not only occupies a large space above the frame, limiting the compactness and flexibility of the air purification device, but also easily leads to electrical safety problems. Since the ionization zone and the dust collection zone require DC high voltages of tens of thousands of volts and several thousand volts respectively, the electrical contact piece is prone to adhere to particulate matter during long-term operation, resulting in reduced surface resistance and increased creepage risk. In addition, the line connectors in existing devices often occupy space in the width direction, resulting in the outer frame of the purification device being too wide, which not only increases the material cost, but also reduces the effective purification area and purification efficiency per unit space.

[0004] Therefore, the prior art needs to be further developed. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned technical deficiencies and provide a highly reliable and infinitely splicable air purification device to solve the technical problems in the related art such as the difficulty in designing the creepage distance of the module external high-voltage power supply, the large space occupied by the electrical box, and the limited splicing flexibility.

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: a highly reliable and infinitely splicable air purification device is provided, comprising: an outer frame, and a module group detachably arranged in the outer frame, the module group is used for ionization and dust collection to purify the air after power is turned on; the module group comprises an inner frame and a high-voltage power supply built in the inner frame, the inner frame is provided with a first interface for exposing the two positive and negative electrical contact pieces of the high-voltage power supply; an electrical box is provided inside the outer frame, the second interface of the electrical box is arranged corresponding to the first interface, so that the electrical contact piece is electrically connected through the first interface and the second interface, and a through hole is provided on the outer frame, and the power lines of the high-voltage power supply and the electrical box pass through the through hole to be connected to the external power supply.

[0007] Furthermore, the high-voltage power supply is located at the top of the inner frame, and the outer frame includes a first frame plate, a second frame plate, a third frame plate and a bottom plate. The first frame plate, the second frame plate, the third frame plate and the bottom plate are connected in sequence to wrap the module group in the outer frame. The electrical box is arranged below the second frame plate so that the second interface is connected correspondingly to the first interface. The first frame plate and the third frame plate are arranged opposite to each other, and the second frame plate and the bottom plate are arranged opposite to each other; one side of the second frame plate is vertically connected to the fourth frame plate, and a perforation is arranged on the fourth frame plate.

[0012] Furthermore, there are multiple support assemblies, which are arranged at intervals. The support assemblies include support columns and buckles. The buckles are buckled on the discharge rod, and the support columns are vertically connected to the buckles to support the conductive plate.

[0013] Furthermore, a groove is provided in the buckle, and the discharge rod is clamped in the groove, thereby extending the creepage distance between the discharge rod and the conductive plate.

[0014] Furthermore, the diameter of the end of the support column close to the conductive plate is larger than the diameter of the end of the support column close to the discharge rod, so as to increase the creepage distance.

[0024] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0025] According to an embodiment of the present invention, a highly reliable and infinitely connectable air purification device is provided. Figures 1 to 11 , comprising: an outer frame 1, and a module group 2 detachably arranged in the outer frame 1, the module group 2 is used for ionization and dust collection to purify the air after being powered on; the module group 2 comprises an inner frame 21 and a high-voltage power supply 22 built in the inner frame 21, and the inner frame 21 is provided with a first interface 23 for exposing two positive and negative electrical contact sheets 221 of the high-voltage power supply 22; an electrical box 11 is arranged inside the outer frame 1, and the second interface of the electrical box 11 is arranged corresponding to the first interface 23, so that the electrical contact sheet 221 is electrically connected through the first interface 23 and the second interface, and the outer frame 1 is provided with a through hole 12 on the same side as the side of the module group 2 facing the airflow, and the power lines of the high-voltage power supply 22 and the electrical box 11 pass through the through hole 12 and are connected to the external power supply. The module group 2 is detachably arranged in the outer frame 1, and when the module group fails or needs maintenance, it can be easily taken out and replaced without disassembling the air purification device as a whole, thereby reducing the maintenance cost and time. The high-voltage power supply 22 is built into the inner frame 21, avoiding the space occupation problem caused by the external placement of the traditional electrical box, making the air purification device more compact. The connection between the high-voltage power supply 22 and the electrical box 11 needs to ensure good electrical isolation and insulation to prevent safety hazards caused by high-voltage leakage. The corresponding setting of the first interface and the second interface enables the electrical contact piece 221 to easily achieve electrical connection without complicated wiring process, thereby improving installation efficiency. The electrical box 11 and the perforation 12 are arranged in the outer frame 1, replacing the traditional external electrical box design. The power lines of the high-voltage power supply 22 and the electrical box 11 can be neatly passed through the outer frame 1 and connected to the external power supply, which not only reduces the external space occupation of the outer frame 1, improves the compactness and flexibility of the device, but also avoids the problem of disorderly lines. Through the docking of the first interface 23 and the second interface, the electrical connection between the electrical contact piece 221 and the electrical box 11 is ensured to be more stable, effectively reducing the safety risks caused by the exposure of the electrical contact part. The high-voltage power supply 22 is built into the module group 2, reducing the chance of particle adhesion and reducing the creepage phenomenon caused by the reduction of surface resistance. The highly reliable and infinitely splicable air purification device of this embodiment solves the technical problems in the related art of large space occupation, limited splicing flexibility, and difficult creepage distance design caused by the external electrical box.

[0026] See also Figure 1 , Figure 2 and Figure 3 In the highly reliable and infinitely splicable air purification device of this embodiment, the high-voltage power supply 22 is located at the top of the inner frame 21, and the outer frame 1 includes a first frame plate 13, a second frame plate 14, a third frame plate 15 and a bottom plate 16. The first frame plate 13, the second frame plate 14, the third frame plate 15 and the bottom plate 16 are connected in sequence to wrap the module group 2 in the outer frame 1, and the electrical box 11 is arranged below the second frame plate 14 so that the second interface is connected to the first interface 23 correspondingly. The first frame plate 13 and the third frame plate 15 are arranged oppositely, and the second frame plate 14 and the bottom plate 16 are arranged oppositely; one side of the second frame plate 14 is vertically connected with the fourth frame plate 17, and the perforation 12 is arranged on the fourth frame plate 17. The high-voltage power supply 22 is located at the top of the inner frame 21, and the electrical box 11 is arranged below the second frame plate 14 and connected to the first interface 23 correspondingly. This layout not only makes the internal structure of the air purification device more compact, but also effectively utilizes the vertical space inside the device, reduces the overall volume, and improves space utilization. The fourth frame plate 17 is the side facing the airflow, that is, the front view angle of installing the air purification device. The perforation 12 is arranged on the fourth frame plate 17 to facilitate the neat passage of the power line to connect to the external power supply, and also provides convenience for the maintenance and replacement of the line.

[0027] See also Figure 2 In the air purification device of this embodiment, the support frame of the electrical box 11 adopts an integrated manufacturing process, and the first frame plate 13 and the third frame plate 15, that is, the two sides of the outer frame 1 are provided with rotation holes 111, and the support frame is connected to the outer frame 1 through the rotation holes 111, and the support frame is rotatable relative to the outer frame 1. Two mounting holes 112 are provided on the fourth frame plate 17, one end of the electrical box 11 is hinged in the rotation hole 111 of the outer frame 1, and the other end is respectively fixed to the fourth frame plate 17 through two fasteners passing through the frame and the mounting hole 112. When the electrical box 11 needs to be repaired, it is only necessary to remove the fasteners on the mounting hole 112 to suspend the support frame in the outer frame for easy maintenance. This design effectively supports the electrical box 11 and greatly reduces the complexity of the assembly process. The frame design has a rotation function and can be flexibly rotated relative to the outer frame 1, so that the operator can easily reach the electrical box 11 by simply rotating the frame without disassembling the entire electrical box, thereby greatly facilitating subsequent maintenance and repair work.

[0028] See also Figure 3 A pull-down active card 113 is provided on the electrical box 11. After the dust collecting module and the field electric module are installed, the field electric module is directly fixed by pulling down the active card 113 to ensure that the field electric module and the dust collecting module are both confined within the outer frame 1 of the purification device. Depending on the design, the field electric module and the dust collecting module can also be designed with active buckles separately.

[0029] See also Figure 2 and Figure 3 In the highly reliable and infinitely splicable air purification device of this embodiment, extension plates 18 are provided on both sides of the first frame plate 13 and the third frame plate 15. The extension plates 18 are perpendicular to the first frame plate 13 and the third frame plate 15. A plurality of splicing holes 19 are provided on the first frame plate 13, the second frame plate 14, the third frame plate 15 and the extension plates 18. The air purification device can be installed and spliced ​​in multiple directions through the extension plates 18 and the splicing holes 19, and multiple air purification devices can be spliced ​​in various directions. The provision of the extension plates 18 enables the air purification device to flexibly connect devices in different directions through the splicing holes 19, supports multi-directional splicing of the device, facilitates the combined use of multiple devices, not only improves the air purification capacity, but also reduces the difficulty of device splicing, improves the assembly efficiency, and enhances the stability of the device after splicing.

[0030] See also Figure 3 , the extension plate 18 is perpendicular to the first frame plate 13 and the third frame plate 15, forming an L-shaped structure extending outward. This design, combined with the extension plate 18 and the splicing hole 19, can realize the rapid splicing between the air purification device monomers. For example, in the purification section of the air conditioner, a vertically placed purification device and a horizontally placed purification device can be quickly spliced ​​through the L-shaped structure, greatly reducing the on-site installation time. The extension plate of one outer frame fits the extension plate of another outer frame, and the fasteners pass through the splicing holes on the two extension plates in turn to realize the horizontal splicing of multiple air purification devices. A raised plate is also provided on the side of the second frame plate and the bottom plate that meets the airflow, and the raised plate is also provided with splicing holes. The fasteners pass through the splicing holes on the raised plate in turn to realize the longitudinal splicing of multiple air purification devices. A bent fold is also provided on each splicing plate with a splicing hole, thereby increasing the connection strength of the splicing plate. After installation, the L-shaped structure can also effectively block the uncovered area or edge space, thereby improving the overall sealing. The standard L-shaped parts that come standard with the factory can be quickly connected to the purification device frame and fixed to the inner frame of the air-conditioning box for easy installation. In addition, the male and female quick connectors on both sides of the front further simplify the installation and maintenance process. Each device is designed with interconnected quick connectors on the left and right, which can be used for quick power connection and assembly. The quick connectors on the front also avoid the problem of the quick connectors being set on the side and occupying the width direction of the purification device. This layout design makes the edges of the purification device frame narrower, providing more available space for the field electric module, dust collection module and primary efficiency module, thereby significantly improving the purification efficiency and dust holding capacity per unit space.

[0031] The air purification device can be composed of a group of module groups 2 (such as Figure 1 As shown), it can also be composed of two groups of module groups 2 (as shown Figure 4 and Figure 5As shown in the figure, each module group 2 is arranged in sequence along the length extension direction of the second frame plate 14. Of course, the module group 2 can also be three or more groups. By increasing the number of module groups, the purification efficiency of the air purification device can be significantly improved. Each module group can independently perform ionization and dust collection operations, thereby jointly improving the overall air purification capacity. The module groups 2 are arranged in sequence along the extension direction of the second frame plate 14, utilizing the longitudinal space inside the outer frame 1, which is convenient for splicing and assembly, and also makes the device more neat and beautiful in appearance.

[0032] Module group 2 includes a dust collecting module 24 and a field electric module 25. The dust collecting module 24 includes a micro-static module, and can also be a plate-type electrostatic dust collecting module. The plate-type electrostatic dust collecting module has various forms: the plate-type electrostatic dust collecting module adopts a staggered arrangement of dust collecting plates, the dust collecting plates adopt an insulator in the middle, and conductive materials on both sides, and the dust collecting plates are bonded together by glue, and voltages of different potentials are passed to adjacent dust collecting plates; the plate-type electrostatic dust collecting module can also adopt a staggered arrangement of dust collecting plates, the dust collecting plates adopt an insulating layer in the middle, and semiconductor layers on both sides of the insulating layer, and the conductive layer is located between the semiconductor layer and the insulating layer, and the dust collecting plates are bonded together by glue, and voltages of different potentials are passed to adjacent dust collecting plates; the dust collecting plates of the plate-type electrostatic dust collecting module can be provided with ports for avoiding glue. During production, dust collecting plates of the same potential are fixed together to ensure the formal spatial distance between dust collecting plates of different potentials. The plate-type electrostatic dust collecting module can also be made of a dust collecting plate made of conductive plastic, or a dust collecting plate in the form of an insulating material wrapped with a conductive material. The dust collecting plate is fixed by gluing or a limiting structure, so that the dust collecting plates with different potentials maintain the same distance, ensuring the stability of the formed electric field and the air purification efficiency. In this embodiment, the micro-electrostatic module 241 is used as an example, and other dust collecting modules such as the plate-type electrostatic dust collecting module are similar.

[0033] The micro-electrostatic module 241 uses dielectric materials to wrap conductive materials to form a flat and dense micro-cavity MESP dust collection module. Adjacent conductive materials are connected to voltages of different potentials to form an electric field, and charged particles are captured when they pass through the electric field. The field electric module 25 uses needle tip discharge, and the needle tip is connected to a DC positive high voltage or a DC negative high voltage. The grounding plate is provided with circular holes, nearly circular holes, etc. The needle tip and the negative plate form an ionization zone, and the particles in the air are charged when passing through.

[0034] The highly reliable and infinitely splicable air purification device of this embodiment is also provided with a baffle on the outer frame 1, one end of the baffle is connected to the second frame plate 14, and the other end of the baffle is connected to the bottom plate 16, and the connection between the baffle and the two adjacent module groups 2 is correspondingly arranged to block the gap between the two adjacent module groups 2. Figure 4 The two micro-electrostatic modules 241 are arranged side by side along the length extension direction of the second frame plate 14 in the use state diagram. Figure 5The figure shows that two electrostatic modules 25 are arranged side by side along the length extension direction of the second frame plate 14. In actual use, three, five or more electrostatic modules 241 and electrostatic modules 25 in each column form a module group 2. Figure 4 This is a diagram of the use status of two groups of module groups 2 arranged side by side. The baffle rod directly blocks the gap between two adjacent module groups 2, effectively preventing unfiltered air or particulate matter from escaping from these gaps, thereby significantly improving the sealing of the air purification device. A sealing cotton strip is provided on the baffle rod to further enhance the sealing effect. The sealing cotton strip has the characteristics of softness and elasticity, and can fit tightly into the tiny gaps between the module groups to ensure no leakage. Due to the presence of the baffle rod and the sealing cotton strip, particulate matter cannot escape at the junction, thereby ensuring that the air inside the air purification device flows through each module group for full purification. This helps to improve the purification efficiency and ensure the quality of the output air.

[0035] A deodorization module is set inside the frame. The deodorization module is located on the downwind side of the dust collection module. The frame has a built-in card slot, which can quickly install and replace the deodorization module. The deodorization module is a module made of activated carbon material, or a deodorization module made of catalytic material. The dirty air passes through the primary filter, then the field electric module, the dust collection module, and finally the catalytic module to purify the particulate matter in the air, kill microorganisms such as bacteria and viruses, and purify gaseous pollutants. The field electric module and the dust collection module are connected with a high-voltage electric field, which can kill microorganisms such as bacteria and viruses; the deodorization module is optional and can be flexibly selected according to purification needs.

[0036] When a single module group 2 is used, that is, only one group of micro-electrostatic modules 241 and field electric modules 25 is used, there is no need to use a barrier rod, and it is only necessary to prevent a gap between the outer frame 1 and the module group 2 .

[0037] See also Figure 4 and Figure 5, the highly reliable and infinitely splicable air purification device of this embodiment adopts a double module group 2. Each module group 2 includes a micro-electrostatic module 241 and a field electric module 25. The micro-electrostatic module 241 is located between the field electric module 25 and the blocking rod. A support assembly 3 is provided on the field electric module 25. One end of the support assembly 3 is connected to the discharge rod 251 of the field electric module 25, and the other end is connected to the conductive plate 252 of the field electric module 25, which is used to support the conductive plate 252 to prevent it from deforming during the ionization process. The discharge rod 251 generates a strong electric field through a high-voltage power supply to ionize the air, charge neutral air molecules, and form charged particles. The conductive plate 252, as the other pole of the electric field, completes the function of purifying the air by adsorbing charged particles. The electric field strength between the discharge rod and the conductive plate determines the ionization efficiency and purification effect. The high-voltage electric field will generate an electric field force on the conductive plate 252, and the mechanical vibration during the operation of the equipment may cause the conductive plate 252 to deform. Once the conductive plate 252 is deformed, it will affect the uniformity of the electric field, reduce the ionization efficiency, and may cause electrical failures, such as creepage or arc breakdown. The support assembly 3 stabilizes the conductive plate 252 to prevent it from deforming under the action of the electric field, ensures uniform distribution of the electric field, improves purification efficiency, and prolongs the service life of the equipment.

[0038] See also Figure 1 and Figure 6 , the field electric module 25 adopts low voltage power supply, and the high voltage power supply is built into the upper end of the field electric module 25, and all are sealed and wrapped. This part of the seal includes two parts, one part is that the high voltage power supply body is completely sealed, and even if there is residual water in the upper end, it will not affect normal use; the other part is that the cavity where the high voltage power supply is placed at the upper end is semi-sealed, and only the drainage holes are opened at the bottom, so that the water can flow out naturally after cleaning, accelerating drying; similar to the field electric module 25, the micro-electrostatic module 241 adopts a similar sealing method, the difference is that the micro-electrostatic module 241 only retains the high voltage line routing space, and the micro-electrostatic module 241 can be provided with drainage holes at the bottom and sides to accelerate its internal drying; the module is designed with an anti-reverse connection device, and the low voltage power supply electrode sheet is asymmetrically designed to prevent customers from installing it in reverse, causing the module to not work.

[0039] See also Figure 6 and Figure 7In the highly reliable and infinitely splicable air purification device of this embodiment, there are multiple support assemblies 3, and the multiple support assemblies 3 are arranged at intervals. The support assembly 3 includes a support column 31 and a buckle 32. The buckle 32 is clamped on the discharge rod 251, and the support column 31 is vertically connected to the buckle 32, so as to support the conductive plate 252. A groove 321 is provided in the buckle 32, and the discharge rod 251 is clamped in the groove 321, so as to extend the creepage distance between the discharge rod 251 and the conductive plate 252. The diameter of the support column 31 near the conductive plate 252 is larger than the diameter of the support column 31 near the discharge rod 251, so as to increase the creepage distance. A high-voltage electric field is formed between the discharge rod 251 and the conductive plate 252. The conductive plate 252 serves as the negative pole of the high-voltage electric field. The conductive plate 252 needs to maintain a flat and fixed position to avoid abnormal distribution of the electric field due to vibration or deformation. The spaced support design of the support column 31 for the conductive plate 252 can disperse the force on the conductive plate and prevent it from being locally deformed due to concentrated stress points; the buckle 32 is directly connected to the discharge rod 251, making the support assembly 3 faster during the connection process; the design of the groove 321 is equivalent to extending the creepage path. The threaded ring 311 provided on the support column 31 not only provides a larger contact area. It indirectly increases the creepage path and also increases the mechanical strength between the conductive plate and the support assembly 3. The position of the thick-diameter component close to the conductive plate 252 provides greater strength and installation space, and the position of the thin-diameter component close to the discharge rod 251 reduces the width of the insulating surface, thereby increasing the creepage distance within the unit space and improving electrical safety.

[0040] See also Figure 8 The highly reliable and infinitely splicable air purification device of this embodiment is also provided with a primary filter 6, which is snapped into the outer frame 1 and is located between the fourth frame plate 17 and the module group 2, and is used to filter out hair, large particles, etc. in the air. On the side of the outer frame 1 that meets the airflow, a safety switch and an electrical switch button are designed to facilitate installation and subsequent maintenance by operation and maintenance personnel. The safety switch uses the height space of the electrical box. The safety switch is embedded in the side of the electrical box that is bent out. A safety switch mounting hole is provided on the side. A travel switch is provided behind the safety switch. After the safety switch is compressed, the circuit remains connected. When the safety switch is not compressed, the circuit is disconnected. The frame of the primary filter compresses the safety switch, and the equipment circuit is connected. During maintenance, the primary filter is opened and the equipment is automatically powered off, thereby avoiding safety accidents of electric shock caused by forgetting to turn off the power and directly opening the equipment. By using the safety switch to utilize the height space of the electrical box, not only can the secondary safety protection of the equipment be achieved, but the safety switch can also be integrated into the electrical box without occupying other space, and the effective purification area of ​​the primary filter 6 per unit space can be increased, which has a certain effect on the stability of the airflow of the purification device, as well as the dust holding capacity and efficiency. The primary filter can be a traditional media filter, or it can be Figure 1 Nylon mesh 61 or Figure 8 The V-shaped folded metal mesh 62 is shown. If the primary filter is relatively large, support is added between the primary filters to maintain strength during operation and prevent deformation. A sealing strip is added to the frame of the primary filter to ensure that large particles such as mosquitoes in the air are fully intercepted.
