Description

Technical Field

[0001] The invention relates to the field of plasma air disinfection generators, and in particular to a plasma air disinfection generator with an adjustment function and an installation method. Background Art

[0002] The plasma generated by a plasma generator is highly effective for air purification, including sterilization. The specific ion tube assembly consists of a glass tube with two electrodes positioned inside and outside the tube. These electrodes are controlled by a driver board, generating plasma, which can be used for air treatment. When using an ion tube assembly, it is typically formed into a module, which is then fixed to a ventilation system, a mobile air purifier, or mounted directly on a wall.

[0003] In ventilation systems, purification effects are generally achieved by opening a window on the side wall of the pipe and then fixing the module on the side wall. However, the width of the pipe limits the length of the ion tube assembly, so it can only be achieved by setting multiple modules in the length direction of the pipe or increasing the size of a single module in the length direction of the pipe. The above two methods are not conducive to product cost and simplification of the installation process, especially installing a module on the side of the pipe has a negative impact on the shape of the pipe or the space in the site. If the elbow head of the air supply duct is completely replaced with a plasma air disinfection generator assembly, then the assembly needs to be matched with a elbow air duct. During the specific installation process, the existing elbow head also needs to be disassembled. What is particularly inconvenient is that the plasma air disinfection generator assembly needs to be able to replace the elbow head in shape and size. Therefore, the plasma air disinfection generator assembly needs to be customized, which greatly increases the cost. Summary of the Invention

[0047] Reference Figures 1 to 11 In one embodiment of the present invention, a plasma air disinfection generator with an adjustment function is applied to an elbow 001 in an air supply and exhaust system, and is characterized by comprising:

[0048] The installation box 100 includes a main box body 110 and a matching portion 120 provided along the length of the main box body 110. A mounting opening 111 is provided on a side of the main box body 110 facing the matching portion 120. A mounting channel 121 corresponding to the mounting opening 111 is passed through the thickness of the matching portion 120. The side of the matching portion 120 facing away from the main box body 110 is used to match the outer wall of the elbow 001.

[0049] A driving plate, disposed in the main housing 110;

[0050] An ion tube assembly group includes a plurality of ion tube assemblies 300, each of which includes interconnected ion tube ends 310 and fixed base ends 320. Adjacent ion tube assemblies 300 are abutted against each other by the fixed base ends 320. The fixed base ends 320 pass through the mounting channel 121 in the length direction and enter the mounting port 111. The ion tube end 310 includes an inner conductive sheet 311 and an outer conductive sheet 312 for applying a voltage. The inner conductive sheet 311 and the outer conductive sheet 312 are led out of one end of the fixed base end 320 away from the ion tube end 310. The ion tube assembly 300 is electrically connected to the drive board via the inner conductive sheet 311 and the outer conductive sheet 312. The mounting channel 121 is tightly fixed to the periphery of the ion tube assembly group.

[0051] The cross section of the fixing seat end 320 is in the shape of a rectangle or a regular hexagon.

[0052] In the prior art, the plasma generated by the plasma generator has obvious effects on air purification functions such as sterilization. The specific ion tube assembly 300 has a glass tube, and two electrodes are arranged inside and outside the glass tube. The above electrodes are controlled by a driving plate to generate plasma, so that the generation of plasma can be used for air treatment. When the ion tube assembly is used, it is generally formed into a module, and then the module is fixed to a ventilation system, a mobile air purifier or directly wall-mounted. In the ventilation system, a window is generally opened on the side wall of the pipe, and then the module is fixed on the side wall to achieve a purification effect. However, the width of the pipe limits the length of the ion tube assembly, so it can only be achieved by arranging multiple modules in the length direction of the pipe or increasing the size of a single module in the length direction of the pipe. The above two methods are not conducive to product cost and simplification of the installation process. In particular, installing a module on the side of the pipe has a negative impact on the shape of the pipe or the space in the site. If the elbow head 001 of the air supply duct is completely replaced with a plasma air disinfection generator assembly, then the assembly needs to be matched with a curved air duct. During the specific installation process, the existing elbow head 001 also needs to be disassembled. What is particularly inconvenient is that the plasma air disinfection generator assembly needs to be able to replace the elbow head 001 in shape and size. Therefore, the plasma air disinfection generator assembly needs to be customized, which greatly increases the cost.

[0053] In the present invention, the length direction of the plasma air disinfection generator and the installation box 100 are both defined by the length direction of the ion tube assembly 300, and the height direction of the two is the vertical direction, and the width direction of the corresponding two corresponds to the length direction setting. The installation box 100 is divided into a main box body 110 and a matching part 120 in the length direction, and the side of the matching part 120 facing away from the main box body 110 is used to match the outer wall of the elbow head 001. Since the size information of the elbow head 001 varies greatly in various specific application scenarios, the installation box 100 also needs to have a corresponding matching structure; therefore, the matching part 120 is introduced, and the matching effect is achieved by the matching part 120, so that the main box body 110 does not need to make matching structural changes, and the overall processing difficulty of the installation box 100 is reduced. During the installation process, the main box body 110 can be fixed to the existing air supply duct or independently hung and installed. The matching part 120 can be prefabricated (for example, after obtaining the size information of the elbow head 001, it can be obtained by 3D printing); or the matching part 120 can be processed on site, and the matching part 120 raw material has an installation channel 121, and the size of the matching part 120 raw material is reserved to be larger and is made of polymer material, so that the matching part 120 raw material is processed at the construction site to adapt to the elbow head 001.

[0054] In order to reduce the processing difficulty and improve the tightness of the arrangement between the ion tube assemblies 300, the present invention does not adopt the method of providing multiple mounting holes corresponding to the ion tube assemblies 300 on the matching part 120 to fix and seal the ion tube assemblies 300. Instead, the ion tube assemblies 300 are fixed to each other using the fixing base ends 320 of the ion tube assemblies 300 themselves. For example, when the matching part 120 is formed by four strip structures connected to each other, the strip structures can be cut and trimmed on site to achieve the matching part 120 to form a shape match with the elbow 001. Figure 11 When the cross section of the fixed seat end 320 is rectangular (including square), the inner wall structure of the main box body 110 and the matching portion 120 corresponding thereto is relatively simple, which has the advantage of being easy to process; Figure 5 When the cross-section of the fixing base end 320 is a regular hexagon, each fixing base end 320 can be surrounded by up to six other fixing base ends 320, thereby improving the stability of the fixing base end 320. In particular, in the present invention, the fixing base end 320 is mainly fixed by the adjacent fixing base ends 320. Therefore, when the cross-section of the fixing base end 320 is a regular hexagon, it has a more obvious fixing advantage. The installation method of the ion tube assembly 300 will be described in detail in the subsequent embodiments.

[0055] Drive plate is arranged on main casing 110, is used to control the work of ion tube assembly 300.A plurality of ion tube assemblies 300 form ion tube assembly group.Ion tube assembly 300 comprises interconnected ion tube end 310 and fixed base end 320, and adjacent ion tube assembly 300 forms abutment by fixed base end 320, and fixed base end 320 passes mounting passage 121 and enters mounting opening 111 in length direction.Adjust the position of ion tube assembly 300 in mounting box 100 length direction to realize coupling with elbow head 001, thereby regulate and realize best air purification effect.Form mutually fixing between the ion tube assembly 300 in center, and peripheral ion tube assembly 300 is by matching portion 120 or also assists fixing by main casing 110.Mounting passage 121 is close to the periphery (being specifically a plurality of fixed base ends 320 form integral periphery) of fixing ion tube assembly group to form high-quality fixing and sealing. The ion tube end 310 includes an inner conductive sheet 311 and an outer conductive sheet 312 for applying voltage. The inner conductive sheet 311 and the outer conductive sheet 312 are led out of the fixed base end 320 away from the end of the ion tube end 310. The ion tube assembly 300 is electrically connected to the drive plate via the inner conductive sheet 311 and the outer conductive sheet 312. The ion tube end 310 also includes a tube body 313, an inner electrode mesh 314, and an outer electrode mesh 315. The inner conductive sheet 311 is connected to the inner electrode mesh 314, and the outer conductive sheet 312 is connected to the outer electrode mesh 315. The tube body 313 and the fixed base end 320 are sealed to form a working chamber. The inner conductive sheet 311 and the outer conductive sheet 312 are both arranged through the fixed base end 320. The preferred arrangement of the specific outer conductive sheet 312 will be further described in subsequent embodiments.

[0056] In summary, the plasma air disinfection generator is installed at the elbow head 001. At this time, the length direction of the ion tube assembly 300 can be consistent with the length direction of the air supply duct. At this time, the length of the ion tube assembly 300 is no longer limited by the width of the air supply duct. At the same time, the plasma air disinfection generator is set at the elbow head 001 to fully utilize the existing space; specifically, the matching portion 120 is used to match the curved shape of the elbow head 001, so that the main box body 110 does not need to make matching structural changes, and the overall processing difficulty of the installation box 100 is reduced; adjacent The ion tube assemblies 300 are supported by the fixed seat ends 320, which pass through the installation channel 121 in the length direction and enter the installation opening 111. The central ion tube assemblies 300 are fixed to each other, while the peripheral ion tube assemblies 300 are fixed with the assistance of the matching part 120 or the main box body 110; the ion tube assemblies 300 are fixed to each other by using the fixed seat ends 320 themselves, which reduces the structural complexity and processing difficulty of the matching part 120 and the main box body 110, and at the same time improves the tightness of the arrangement of the ion tube assemblies 300.

[0057] Reference Figures 1 to 9 In one embodiment, the mating surface of the main box body 110 and the matching portion 120 has a tendency of being 30 to 75 degrees with respect to the length direction of the main box body 110 .

[0058] The surface (top surface) of the main housing 110 that mates with the matching portion 120 is not limited to a flat surface; it may also be curved or other shapes. Specifically, the main housing 110 may have an inclined angle across its width. Since the matching portion 120 is used to achieve alignment with the elbow 001, if the surface of the main housing 110 that mates with the matching portion 120 is perpendicular to the length of the main housing 110, the matching portion 120 would need to be larger. This would not only be detrimental to its processing, but also potentially problematic for securing the ion tube assembly 300 and wasteful for the material of the mounting box 100. In this embodiment, by arranging the surface of the main housing 110 that mates with the matching portion 120 to be inclined, alignment with the elbow 001 is achieved as closely as possible, allowing the matching portion 120 to be smaller. One surface of the main box body 110 in the length direction is the top surface, that is, the surface that cooperates with the matching part 120, and the other surface of the main box body 110 in the length direction is the bottom surface. In one embodiment, the top surface of the main box body 110 can be parallel to its bottom surface. At this time, the main box body 110 not only meets the beneficial effects of the previous embodiment, but also has the effect of continuing to reduce its volume.

[0059] In one embodiment, the mating surface of the main box body 110 and the matching portion 120 is a plane.

[0060] When the top surface of the main box 110 is a curved surface, it may form a good match with the outer shape of the elbow 001. However, in order to prevent the main box 110 from becoming a customized component, the present invention introduces the matching portion 120, so the structure of the main box 110 is simplified. In this embodiment, the top surface of the main box 110 is set to be flat, so the matching portion 120 is fully used to adapt the elbow 001, which reduces the difficulty of processing the main box 110. During the design and installation process, the top surface of the main box 110 can be tangent to the middle of the bend of the elbow 001, so the size of the matching portion 120 can be set to be smaller.

[0061] In one embodiment, the plurality of ion tube assemblies 300 in the installation box 100 are arranged in a rectangular array, and the plurality of ion tube assemblies 300 in each column in the height direction of the plasma air disinfection generator are fixedly connected.

[0062] In the invention, due to the structural characteristics of plasma air disinfection generator, a plurality of ion tube assemblies 300 are closely arranged and become possibility.In the present embodiment, a plurality of ion tube assemblies 300 are arranged in rectangular arrays, and the degree that the ion tube assemblies 300 of its different positions on the width direction of installation box 100 stretch into elbow 001 is inconsistent, thereby realizes the utilization maximization of each ion tube assemblies 300; And the cross section of elbow 001 inner chamber is rectangular substantially, and the installation condition of the ion tube assemblies 300 in every row of plasma air disinfection generator in height direction is consistent.Now the ion tube assemblies 300 in every row are fixedly connected, so in the field installation process, the debugging process for ion tube assemblies 300 is simplified.For example, a plurality of ion tube assemblies 300 are with height direction three, and four modes of width direction form array, and when three ion tube assemblies 300 in every row of height direction form fixedly connected in advance, the workload that installs and debugs for ion tube assemblies 300 is reduced to 1 / 3rd on the scene.

[0063] Reference Figure 8 In one embodiment, the ion tube end 310 is sleeved in the fixed base end 320 , and the free end of the outer conductive sheet 312 near the ion tube end 310 is disposed between the fixed base end 320 and the ion tube end 310 .

[0064] In the prior art, a spring-type conductive sheet is generally provided on the outer surface of the mounting box 100, and an electrical connection is formed with the outer electrode mesh 315 of a single or multiple ion tube assemblies 300 through the spring-type conductive sheet. However, due to the special fixing method of the ion tube assemblies 300 in the present invention and the complexity of the positional relationship between them, the above-mentioned conductive sheet is difficult to function. In this embodiment, the free end of the outer conductive sheet 312 near the ion tube end 310 is set at the position of the fixed seat end 320, so that the installation process of the ion tube end 310 does not need to consider the influence of the outer conductive sheet 312 at all, which provides convenience for the overall installation. The specific installation method of the outer conductive sheet 312 can be various. For example, the outer conductive sheet 312 is a columnar structure that passes through the thickness direction of the fixed seat end 320, one end of which is used to connect the wire, and the other end of which is used to connect the electrode sheet. The above electrode sheet forms an electrical contact with the outer electrode mesh 315.

[0065] In one embodiment, the fixing seat end 320 is provided with an adhesive layer on the outer periphery of the main box body 110 .

[0066] In the present invention, the fixing base ends 320 are fixed to each other (the fixing base ends 320 at the edge are also fixed to the main housing 110 by the matching portion 120), so the dimensions of the fixing base ends 320 are closely matched. The adhesive layer applied to the periphery of the ion tube assembly 300 is easily squeezed out during installation (especially during installation of the last row or column of ion tube assemblies 300), thus losing its adhesive effect. Moreover, the addition of an adhesive layer at the position of the fixing base ends 320 corresponding to the main housing 110 is not conducive to the disassembly process. In this embodiment, the adhesive layer enhances the fixing and sealing effect between the fixing base ends 320 and is only provided outside the main housing 110, thereby improving ease of use.

[0067] The present invention also provides an installation method, which is applied to the above-mentioned plasma air disinfection generator with adjustment function, comprising:

[0068] S1. Obtain the size information of elbow 001 in the air supply and exhaust system;

[0069] S2, making the matching part 120 according to the size information;

[0070] S3, installing the plurality of ion tube assemblies 300 on the main housing 110 and the matching portion 120;

[0071] S4, sealing the gaps between the multiple fixed seat ends 320;

[0072] S5. Processing the installation window 010 on the elbow 001;

[0073] S6. Fix the main box 110 to the air supply and exhaust system or an external fixed structure, and extend the multiple ion tube assemblies 300 into the installation window 010 as a whole;

[0074] S7. Seal the gap between the matching portion 120 and the elbow 001.

[0075] In this embodiment, the above step numbers serve to distinguish and do not limit the order of implementation.

[0076] Steps S1 to S2 are for obtaining the matching portion 120 . This is not limited to pre-fabrication after obtaining the dimensional information; it can also be fabricated on-site after obtaining the dimensional information. After obtaining the dimensional information of the elbow 001 , the corresponding model and size of the main housing 110 can be selected. In practice, the model of the main housing 110 is primarily determined by the number of ion tube assemblies 300 , so the number of models of the main housing 110 is relatively small.

[0077] In step S5, a mounting window 010 is machined into the elbow 001 to accommodate the insertion of the multiple ion tube assemblies 300. In the present invention, the core purpose is to machine the mounting window 010 into the elbow 001, rather than replacing it. This reduces workload while minimizing modifications to the existing ventilation system. It should be noted that during the development of the technical solution of the present invention, consideration was given to machining a cluster of holes corresponding to the multiple ion tube assemblies 300 into the elbow 001. However, this was found to be difficult and inefficient. Consequently, the matching portion 120 and the mounting window 010 were developed to address this issue.

[0078] In step S3, after the ion tube assembly 300 is installed in the main housing 110, the matching unit 120 is placed around the outer periphery of the entire structure formed by the multiple ion tube assemblies 300. In some embodiments, the main housing 110 and the matching unit 120 can be fixed to improve the sealing effect and the structural stability of the matching unit 120, such as by applying structural adhesive between the main housing 110 and the matching unit 120. During the installation of the ion tube assembly 300, the electrical connection process can be completed simultaneously.

[0079] In step S4, the gaps between the fixed seat ends 320 may be sealed to varying degrees. Sealing medium may be filled only at both ends of the length direction of the fixed seat ends 320; or the gaps between adjacent fixed seat ends 320 in the circumferential direction may be filled with sealing medium to enhance the sealing effect.

[0080] In step S7, the gap between the matching portion 120 and the elbow 001 is filled with tape, glue or foam glue, so that the sealing effect between the two is improved and the negative impact on the operation of the existing ventilation system is reduced.

[0081] In one embodiment, the step S3 includes:

[0082] Adhesive is applied to the outer periphery of the fixing seat end 320 .

[0083] By curing the applied adhesive, the fixing effect and sealing effect between the fixing seat ends 320 are improved.

[0084] In one embodiment, the step S3 includes:

[0085] S3.1. Connect the plurality of ion tube assemblies 300 in each column of the plasma air disinfection generator in the height direction to form an entire ion tube assembly column;

[0086] S3.2, combining the matching unit 120 with the main housing 110;

[0087] S3.3. Apply adhesive to the inner wall of the matching portion 120;

[0088] S3.4. After the previous ion tube assembly row is installed as a whole and adhesive is applied to the outer peripheral wall of the fixed seat end 320 exposed outside the main box 110, the next ion tube assembly row is installed as a whole until all ion tube assemblies 300 are installed. The installation position of the first ion tube assembly row as a whole is on the side of the matching part 120 in the width direction close to the center of curvature of the elbow head 001 in the length direction.

[0089] In the present embodiment, step numbering is only done to distinguish, and does not fully limit the implementation order. In the step of S3.1, the connection mode between the ion tube assembly 300 can be clamping, buckling or bonding etc., and the fixing between the above ion tube assembly 300 can be carried out in advance or carried out on the scene. The cross section of the elbow head 001 inner cavity is substantially rectangular, and the installation condition of the ion tube assembly 300 in each row of the plasma air disinfection generator is consistent. At this moment, the ion tube assembly 300 in each row is fixedly connected, so in the on-site installation process, the debugging process for the ion tube assembly 300 is simplified. For example, a plurality of ion tube assemblies 300 are in height direction three, and the mode of width direction four forms array. When the three ion tube assemblies 300 in each row of the height direction are fixedly connected in advance, the workload of installing and debugging the ion tube assembly 300 on the scene is reduced to one-third. It should be noted that, above, the process of forming a plurality of ion tube assemblies 300 in each row to be connected can reduce the processing of subsequent coating adhesive.

[0090] In steps S3.2 and S3.3, the matching portion 120 is combined with the main housing 110, and an adhesive is applied on the inner wall of the matching portion 120 to form a foundation for the subsequent fixing of the ion tube assembly 300.

[0091] Step S3.4 describes a preferred installation sequence. The initial installation position for the entire ion tube assembly array is on the side of the matching portion 120, near the longitudinal center of curvature of the elbow 001. In this case, the subsequent ion tube assembly arrays extend longitudinally beyond the previous ion tube assembly array. Therefore, during the adhesive application process, the adhesive can be applied to the entire outer circumference of the fixed base end 320, which is exposed outside the main housing 110, to avoid under- or over-coating. This process is easy to operate, precise, and accurate, resulting in excellent bonding results.

[0092] In one embodiment, in step S2, the matching portion 120 is processed by 3D printing.

[0093] Because the matching portion 120 is curved and needs to specifically match the shape of the elbow 001, and the ion tube assembly 300 must pass through the matching portion 120, there are many interfaces. Using other processing methods would be inefficient and difficult to ensure accuracy. In this embodiment, using the dimensional information of the elbow 001, 3D printing is used to produce the matching portion 120, which is simple, accurate, and fast.

[0094] In summary, the plasma air disinfection generator with adjustment function and the installation method provided by the present invention are implemented so that the plasma air disinfection generator is installed at the elbow head 001. At this time, the length direction of the ion tube assembly 300 can be consistent with the length direction of the air supply duct, and the length of the ion tube assembly 300 is no longer limited by the width of the air supply duct. At the same time, the plasma air disinfection generator is arranged at the elbow head 001 to fully utilize the existing space; specifically, the matching part 120 is used to match the curved shape of the elbow head 001, so that the main box body 110 does not need to make matching structural changes, and the overall processing difficulty of the installation box 100 is reduced; adjacent ion tube assemblies 300 are abutted by the fixed seat end 320, which reduces the structural complexity and processing difficulty of the matching part 120 and the main box body 110, and also improves the tightness of the arrangement between the ion tube assemblies 300.

[0095] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
