Description

Technical Field

[0001] This invention relates to an airflow guiding device, and more particularly to a gas guiding device that simplifies the assembly of components, has a robust structure, and enhances the airflow guiding effect. Background Technology

[0002] To address the problem of traditional gas circulation devices that employ side-draft and side-exhaust, whose winding and complex flow channels significantly reduce airflow velocity and consequently lower dust removal and cleaning efficiency, the applicant's previous Taiwan Invention Patent Application No. 110139304 describes a vertically inlet and outlet gas guiding device. This device comprises a main body and an air guiding unit. In use, airflow is pumped vertically into the main body through an inlet, impacting a guiding element and splitting into two longitudinal directions. The airflow then passes through a perforated guide plate, ensuring even distribution to a collection channel within the air guiding component. Finally, it is ejected vertically from a nozzle to remove dust from the object to be cleaned. During dust removal, the main body's intake port draws in the raised dust vertically, and the dust is then exhausted vertically through an exhaust channel surrounding the air guiding unit, exiting through an exhaust port on the main body, thus achieving dust removal and cleaning.

[0003] Existing gas guiding devices utilize a vertically oriented air intake to perform airflow delivery and dust extraction. This not only offers the advantages of a short flow path and high flow velocity but also significantly enhances dust removal and cleaning efficiency. However, this type of guiding unit uses two longitudinal inner wall plates to separate the air jet space. While this facilitates the assembly of the guiding element and the air guiding assembly, it also increases the overall component size. Furthermore, the air guiding plate is made of a thin plate with numerous perforations, making the manufacturing process relatively complicated. Moreover, as the overall size (lateral length) of the gas guiding device increases with usage conditions, there is a concern that the thin and long plate structure may deform after assembly, thereby reducing its service life. Summary of the Invention

[0005] Therefore, the gas guiding device proposed in this invention includes: a body, a hollow shell in the shape of a long rectangle, having at least one air inlet and at least one air outlet disposed on the top of the body, and a plurality of air intakes located at the bottom of the body.

The inner layer plate has a boss that surrounds the perforation and forms a step difference with the top surface of the inner layer plate. The step difference extends along the length direction of the inner layer plate and is connected to the exhaust channel.

[0012] According to the gas guiding device of the present invention, the guiding port of the guiding component is formed between two guiding elements, and the diameter of the two guiding elements relative to each other is larger than the diameter of the perforation of the guiding unit.

[0014] According to the gas guiding device of the present invention, each of the aforementioned guiding members of the guiding assembly is provided with a connecting portion arranged along the length direction at its bottom, and the top of the aforementioned collecting plate is embedded in the connecting portion of the aforementioned guiding member.

[0056] 500: Object. Detailed Implementation

[0057] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention. (Refer to...) Figure 1 and Figure 2A first preferred embodiment of the gas guiding device 1 of the present invention includes a body 100, a guiding unit 200, at least one air inlet 300, and at least one exhaust pipe 400. The gas guiding device 1 utilizes a vertically oriented air inlet to perform airflow delivery and dust suction, which has the advantages of short flow channels and high flow rates, and can multiply the dust removal and cleaning effect.

[0058] Continue to refer to Figure 3 The body 100 comprises a hollow shell component in the shape of a long rectangle, consisting of an outer layer plate 10, two side plates 20, and two side covers 30. The body 100 has at least one air inlet 11 and at least one exhaust outlet 12 located at its top, and several air intakes 13 located at its bottom. In this embodiment, the air inlet 11 is located in the middle of the outer layer plate 10, and there are two exhaust outlets 12 located on either side of the air inlet 11. Alternatively, the number of air inlets 11 can be multiple, as long as they are evenly distributed on the outer layer plate 10 with the exhaust outlets 12 and meet the pressure balance requirements.

[0059] The outer plate 10 of the main body 100 has two joint portions 14 disposed on both sides of the bottom along the longitudinal direction. The aforementioned side plate 20 has an L-shaped cross-section and is symmetrical to each other, and has a set of straight sidewalls 21 disposed on the joint portion 14, and a bottom wall 22 extending inward from the straight sidewalls 21. The aforementioned side cover 30 is correspondingly clamped to the two ends of the aforementioned side plate 20, and has an upper slot 31, a lower slot 32, at least one insertion hole 33, a locking block 34, and two longitudinal grooves 35 located on both sides.

[0060] The flow guiding unit 200 is housed inside the body 100 and has an inner layer plate 40 extending along the longitudinal direction of the body 100, a perforation 41 penetrating the inner layer plate 40 and directly opposite the air inlet 11, a flow guiding assembly 50 connected to the bottom of the inner layer plate 40, a flow collecting assembly 70 connected to the bottom of the flow guiding assembly 50 and forming a flow collecting channel 60, and an exhaust port 61 disposed at the bottom of the flow collecting assembly 70. An exhaust channel 62 communicating with the air intake 13 is defined between the side plate 20 of the body 100, the flow collecting assembly 70, and the inner layer plate 40.

[0061] The inner layer plate 40 has a boss 43 surrounding the perforation 41 and forming a step 42 with the top surface of the inner layer plate 40, and an inverted U-shaped fitting portion 44 extending longitudinally on the bottom surface of the inner layer plate 40. The step 42 extends longitudinally along the inner layer plate 40 and communicates with the exhaust channel 62. The step 42 of the inner layer plate 40 and the body 100 define a space 45 communicating with the exhaust channel 62. Figure 4 .

[0062] The drainage assembly 50 includes two drainage members 51 and 52 with trapezoidal cross-sections that correspond to each other and extend along the longitudinal direction, a drainage port 53 that extends along the longitudinal direction and corresponds to the perforation 41 and the collection channel 60, and two connecting portions 54 respectively disposed at the bottom of the aforementioned drainage members 51 and 52 and disposed along the longitudinal direction. The tops of the aforementioned drainage members 51 and 52 are embedded in the connecting portion 44 of the inner layer plate 40. The inlet 53 is formed between two inlet components 51 and 52. The inlet 53 has a V-shaped tapering section 531, a straight section 532, and an inverted U-shaped expanding section 533. After the airflow is concentrated and guided into the inlet through the V-shaped tapering section 531, it rushes downward along the narrow straight section 532, and then is ejected from the expanding section 533 and flows into the collection channel 60, so that the airflow is accelerated after passing through the inlet 53 of the inlet component 50.

[0063] Furthermore, the diameter of the two guide elements 51 and 52 when they meet is larger than the diameter of the perforation 41 of the flow guiding unit 200. This not only prevents airflow leakage but also allows the airflow to flow through the guide port 53 to the collection channel 60. The robust structure of the guide elements 51 and 52 is sufficient to withstand the impact of high-pressure airflow without any concern about deformation. In addition, the aforementioned guide elements 51 and 52 are generally inverted trapezoidal in shape, with a long-extending inclined side 55 near the outer bottom edge of the side plate 20. When dust removal and exhaust are performed, this inclined side 55 helps to guide the airflow, making the exhaust operation faster.

[0064] The flow collection assembly 70 corresponds to the flow inlet 53 and includes at least one flow collection plate 71 disposed at the bottom of the flow collection assembly 50, and at least one airflow guide 72 disposed inside the flow collection channel 60. The top of the aforementioned flow collection plate 71 is embedded in the joint 54 of the aforementioned flow guides 51 and 52.

[0065] In this embodiment, the aforementioned collector plate 71 has a wide diameter section 73 and a converging section 74 extending from top to bottom. There are several airflow guides 72 (three airflow guides 72 are shown in this embodiment, but this is not a limitation). The cross-section of the aforementioned airflow guides 72 is arc-shaped, extends along the length direction, and is spaced apart within the wide diameter section 73. The jet nozzle 61 of the flow guiding unit 200 is formed at the bottom of the aforementioned collector plate 71 and adjacent to the converging section 74. The flow collecting assembly 70 has two flow collecting plates 71 arranged symmetrically. The jet nozzle 61 of the flow guiding unit 200 is located at the bottom of the aforementioned flow collecting plates 71 and is connected to the flow collecting channel 60. The wide diameter section 73 of the aforementioned flow collecting plate 71 is formed by a straight flow collecting surface 731 located on the inner side, and the converging section 74 is formed by a wavy flow collecting surface 741 located below the straight flow collecting surface 731. The diameter of the jet nozzle 61 is uniform and smaller than the maximum diameter of the converging section 74, while the diameter of the converging section 74 is smaller than the diameter of the wide diameter section 73. When the airflow is rapidly ejected from the flow guiding port 53 of the flow guiding assembly 50, it flows smoothly and unobstructed along the arc circumference of the aforementioned airflow guide 72, then flows meanderingly through the wavy flow collecting surface 741 of the converging section 74, and finally is rapidly ejected outward through the straight jet nozzle 61.

[0066] The air inlet 300 is connected to the air inlet 11 to pump external airflow into the body 100. In this embodiment, the air pressure source is generated by an air supply blower, which is not shown in the figure.

[0067] The exhaust pipe 400 corresponds to and is connected to the number of exhaust ports 12 to pump the airflow outward from the body 100. In this embodiment, the suction is generated by an air intake blower, not shown in the figure.

[0068] In this embodiment, the connection and combination of each component is secured by screws and screw holes. Welding can also be used to make the connection between the components tighter and less prone to loosening. This is a general locking and fixing method, which is not clearly shown in the figure and will not be described in detail.

[0069] During assembly, the outer layer plate 10, the flow guiding component 50, the flow collecting component 70, and each of the side plates 20 are arranged sequentially from top to bottom. Then, the two side covers 30 are clamped onto the two ends of the aforementioned components, so that the outer layer plate 10 overlaps the top of the two side covers 30. The inner layer plate 40 and the aforementioned flow guiding components 51 and 52 are both accommodated in the upper slot 31 of the side cover 30. The two ends of the two flow collecting plates 71 are accommodated in the lower slot 32 of the side cover 30. The two ends of the aforementioned airflow guiding component 72 are both inserted into the insertion hole 33. The two ends of the two side plates 20 are embedded in the longitudinal groove 35 of the side cover 30. The locking blocks 34 of the side cover 30 are blocked on both sides of the jet nozzle 61. Finally, the components are locked and fixed by screws (or by welding). In addition, the combination relationship between the flow guiding component 50, the flow collecting component 70 and the two side covers 30 of the flow guiding unit 200 is not only connected by the embedding method, but also has corresponding equal number of locking holes 36, 56 and 75 respectively on the two sides of the aforementioned side cover 30, the two sides of the aforementioned flow guiding components 51 and 52 and the two sides of the aforementioned flow collecting plate 71, and is locked with equal number of bolts. In this way, the combined structural strength of the flow guiding component 50 and the flow collecting component 70 is improved, and the stable flow of air during air intake and exhaust is ensured, so that the gas guiding device 1 has a good performance.

[0070] Regarding the use of the gas guiding device 1 of the present invention, during dust removal and cleaning operations, such as Figure 3 and Figure 5 As shown, when airflow is pumped in from the air inlet 11 of the outer layer plate 10, it passes through the perforation 41 of the inner layer plate 40 and splits into two streams along its length. Then, it flows downwards from the inlet 53 between the two guide members 51 and 52. The airflow experiences its first acceleration through the tapering section 531, the straight section 532, and the expanding section 533 of the inlet 53, allowing the airflow to flow evenly and rapidly towards the collecting channel 60. The airflow entering the collecting channel 60 first flows smoothly downwards along the arcuate circumference of the aforementioned airflow guide 72, then enters the converging section 74 and rapidly flows downwards in a curved shape through the wavy collecting surface 741. Finally, it is ejected through the constricted jet nozzle 61 to remove dust from the object to be cleaned. Figure 4 Next, the dust raised by the aforementioned air intake 13 is drawn vertically, flows through the exhaust channel 62 surrounding the outside of the flow guiding unit 200, and then flows into the space 45 on the longitudinal step 42 of the inner layer plate 40. After that, it is guided outward by the exhaust port 12 of the outer layer plate 10, and finally the exhaust pipe 400 is drawn outward to achieve the function of dust removal and cleaning.

[0071] Furthermore, the bottom wall 22 of the aforementioned side plate 20 of the main body 100 of the present invention is shaped such that it is inclined upward from the straight side wall 21 toward the collection assembly 70, so that a gap 63 is formed between the bottom wall 22 of the aforementioned side plate 20 and the collection assembly 70. When dust removal and exhaust are performed, this gap 63 helps to quickly absorb an object 500.

[0072] In addition, such as Figure 6 As shown, in response to different object shapes 500, by adjusting the inclination angle of the bottom wall 22 of the aforementioned side plate 20, the included angle between the straight side wall 21 and the bottom wall 22 is reduced to a smaller value, and the gap 63 between the bottom wall 22 of the aforementioned side plate 20 and the collection assembly 70 is increased, making it more suitable for use on arc-shaped objects 500, so as to enhance the suction of objects and make the dust removal efficiency better.

[0073] Furthermore, in this invention, a plurality of locking holes 37 are provided on the periphery of the side cover 30 of the main body 100, as shown in the figure. Figure 1 and Figure 2 In this way, depending on the needs of the object, by combining several locking components 38, it is easy to expand its use. For example, two or four gas guiding devices can be connected in series or parallel to meet the requirements. Moreover, both vertical and horizontal expansion are possible. Figure 7 .

[0074] In summary, compared to the numerous components and usage problems of existing gas guiding devices, the effectiveness and advantages of the gas guiding device of this invention are summarized as follows:

[0075] I. Because the present invention eliminates the need for the inner wall plate and the thin, porous air guide plate of the past, the overall components are more streamlined.

[0076] Second, in addition to using a stacked arrangement with screws to combine the components of this invention, the components are also combined using an interlocking arrangement, resulting in a stable overall structure with relatively increased structural strength and extended service life.

[0077] Third, the airflow guiding unit 200 of the present invention uses the airflow guiding component 50 to connect with the airflow collecting component 70 to guide the airflow. By setting up a staggered flow channel with a narrowed diameter and an expanded diameter, it can produce the effect of airflow oscillation, thereby accelerating the flow of airflow and improving jet efficiency.

[0078] Fourth, the present invention utilizes the flow port 53 between the two flow guides 51 and 52 to accelerate the flow of air. The arrangement of the two flow guides 51 and 52 not only improves the overall resistance to direct impact from high-pressure airflow, but also ensures that the gas flow guide device does not deform and extends its service life. Furthermore, the longer the length of the gas flow guide device, the more significant its strength will be.

[0079] Fifth, compared with the existing thin porous guide plate which must be punched, the flow guide component 50 of the present invention is composed of two flow guides 51 and 52 along the length direction. The structure is simple and does not require additional processing. Therefore, it has the advantage of saving processing and manufacturing costs. In addition, depending on the different usage conditions, it is only necessary to thicken or lengthen the two flow guides 51 and 52, which makes manufacturing easier and faster.

[0080] It is worth mentioning that, in order to increase exhaust efficiency, the present invention further provides a plurality of inclined edges 76, 77 on the outer periphery of the collecting plate 71 of the collecting assembly 70 and near the exhaust port. The inclined edges 76, 77 of the aforementioned collecting plate 71 and the guide members 51, 52 assist in guiding the airflow, thereby accelerating the efficiency of dust removal and exhaust.

Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
