Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal equipment, specifically relating to a dust collection device. Background Technology

[0002] In modern industrial sectors such as automotive repair and detailing, industrial manufacturing, electrical appliance production, and machining, cleaning is a core process for ensuring product quality, equipment precision, and production safety. As industrial production demands increasingly higher levels of cleanliness for components, efficient and convenient cleaning tools have become a critical need across various sectors. Among these, dust blowers, with their advantages of practicality, ease of operation, and high cleaning efficiency, are widely used to remove dust, powder, debris, and residual moisture adhering to the inner and outer surfaces of machine parts, making them an indispensable basic tool in current industrial cleaning scenarios.

[0003] Currently, most mainstream dust blowers in the industry use compressed air as their driving source. This compressed air method can effectively meet basic cleaning needs when cleaning the outer surface of parts or in open spaces. In normal operating scenarios, compressed air can directly blow away light impurities from the surface of parts, completing the cleaning without disassembling the parts. This significantly reduces operational complexity and operation time, and therefore, it has been widely adopted in mass production and routine maintenance.

[0004] However, existing air blowers have significant limitations in cleaning the interiors of semi-enclosed spaces, components with complex or deep cavities. On one hand, when the component cavity is deep, has many internal corners, or contains obstructions, compressed air entering the cavity easily forms a swirling airflow, causing dust, debris, and other impurities to circulate within the cavity and fail to escape. On the other hand, for larger particles, higher compressed air pressure is required; insufficient pressure makes it difficult to provide continuous thrust to remove impurities from the cavity. Furthermore, some impurities are blocked by corners or obstructions under the influence of airflow and fall back, further exacerbating the cleaning obstruction problem. These issues not only result in poor cleaning performance but also necessitate repeated operations to improve cleanliness, significantly increasing operation time and reducing overall production efficiency, failing to meet the industrial demand for efficient cleaning of components with complex cavities.

[0005] In summary, how to provide a universal device capable of cleaning dust particles in semi-enclosed spaces or large and deep cavities is a technical problem that urgently needs to be solved by people in related fields. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides a dust collection device that achieves dust removal while reducing environmental limitations through the combination of a blower, a three-way connector, and a limiting tube, and is also versatile.

[0007] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a dust collection device, including: A blower gun, which has a blower barrel and a blower nozzle at one end of the blower barrel; The three-way connector has a first branch pipe, a second branch pipe and a third branch pipe. The first branch pipe is connected to the blow gun pipe, the second branch pipe is provided with a dust suction port, and the third branch pipe is connected to a dust collection port. The first branch pipe and the third branch pipe are coaxially arranged. A limiting tube is movably sleeved on the outside of the dust blower barrel. The limiting tube is connected to a locking fastener and is fixedly connected to the dust blower barrel by the locking fastener. The outer diameter of the limiting tube is adapted to the inner diameter of the first branch pipe, and the limiting tube abuts against the inner side wall of the first branch pipe. By adjusting the relative position of the limiting tube and the dust blower barrel, the dust blower nozzle is located in the area where the hollow structure of the second branch pipe extends axially.

[0008] In some implementations, the blower barrel includes a main blower section and a blower section, with the blower section tilted away from the second branch pipe.

[0009] In some implementations, the blow nozzle is located on the central axis of the second branch pipe.

[0010] In some implementations, the central axis of the second branch is perpendicular to the central axis of the first and third branches.

[0011] In some implementations, at least two locking fasteners are distributed and connected on the limiting tube along its extension direction.

[0012] In some implementations, the locking device is a clamp.

[0013] In some implementations, the suction port is connected to a suction component, and the dust collection port is connected to a dust collection component.

[0014] In some implementations, the vacuuming assembly includes a vacuum tube and a vacuum nozzle located at the end of the vacuum tube.

[0015] In some implementations, the dust collection assembly includes a dust collection pipe and a dust collector located at the end of the dust collection pipe.

[0016] In some implementations, the suction nozzle includes ring-shaped comb teeth.

[0017] In summary, this utility model has at least the following advantages: This utility model provides a dust collection device that, through the cooperation of a blower, a three-way connector, and a limiting tube, achieves efficient dust removal while reducing environmental limitations, and possesses wide versatility, suitable for various working conditions. Specifically, the three branches of the three-way connector are respectively connected to the blower, the suction port, and the dust collection port. The blower and the dust collection port are connected and located on the same axis. When the blower operates, a negative pressure is formed between the channel containing the first to third branches and the channel containing the second branch, causing air to enter the second branch from the suction port and move towards the dust collection port, achieving the technical effect of dust removal. Compared to the traditional method of removing dust by applying compressed air pressure, this dust collection device uses negative pressure dust removal, effectively preventing dust from circulating and accumulating within the cavity, thus enabling cleaning in semi-enclosed spaces or larger, deeper cavities. Furthermore, the cooperation between the limiting tube and the blower tube allows the blower tube to be adapted to different three-way connectors, and also helps adjust the positional relationship between the blower tube and the three-way connector, ensuring smooth cleaning.

[0026] Example 1: Please refer to Figures 1 to 2 This embodiment provides a dust collection device. Through the cooperation of a blower 100, a three-way connector 200, and a limiting tube 120, the dust collection device can achieve efficient dust removal while reducing environmental limitations. It also has wide versatility and is suitable for various working conditions.

[0027] Specifically, the vacuuming device includes a blower gun 100 and a three-way connector 200. The blower gun 100 is provided with a blower tube 110, and a blower nozzle 111 is provided at one end of the blower tube 110. When the blower gun 100 is working, it blows air, and the airflow is blown out from the blower nozzle 111 along the blower tube 110.

[0028] The three-way connector 200 has a first branch pipe 210, a second branch pipe 220, and a third branch pipe 230, and the different branch pipes are interconnected. The first branch pipe 210 is connected to the blow gun pipe 110, and the blow gun nozzle 111 is located inside the three-way connector 200, specifically within the region where the hollow structure of the second branch pipe 220 extends axially. The second branch pipe 220 has a suction port 221, and the third branch pipe 230 is connected to a dust collection port 231. Specifically, the first branch pipe 210 and the third branch pipe 230 are coaxially arranged, and the blow gun nozzle 111 faces the dust collection port 231.

[0029] When the dust blower 100 is in operation, the gas blown out by the dust blower 100 flows along the direction from the first branch pipe 210 to the dust collection port 231, resulting in a negative pressure between the space between the first branch pipe 210 and the third branch pipe 230 and the second branch pipe 220. Under the action of negative pressure, external dust and other impurities enter the three-way connector 200 from the dust suction port 221, and are finally discharged from the dust collection port 231 along the direction of the gas blown out by the dust blower 100.

[0030] Compared to the traditional method of removing dust by applying pressure with compressed air, this vacuum cleaner uses negative pressure to remove dust, effectively avoiding the formation of swirling airflow and reducing the restriction on the movement of impurities by corners or obstructions inside the cavity. Therefore, it helps to remove dust, dust and other impurities.

[0031] It should be noted that a limiting tube 120 is movably sleeved around the periphery of the dust-blowing gun barrel 110. The outer diameter of the limiting tube 120 is adapted to the inner diameter of the first branch pipe 210. When the limiting tube 120 is connected to the tee connector 200, the limiting tube 120 abuts against the inner wall of the first branch pipe 210, thereby ensuring that the dust-blowing gun barrel 110 can be stably connected within the tee connector 200, ensuring structural stability and promoting stable airflow. On the one hand, by changing the diameter of the limiting tube 120, the dust-blowing gun barrel 110 can be adapted to tee connectors 200 of different sizes. On the other hand, the length of the limiting tube 120 can be adjusted according to the length of different dust-blowing gun barrels 110 or the position of the dust-blowing nozzle 111, thereby adjusting the position of the dust-blowing nozzle 111 relative to the axially extending region of the hollow structure of the second branch pipe 220. The area referred to here is the region along the axis of the second branch pipe 220, projected onto the direction from the first branch pipe 210 to the third branch pipe 230, i.e., the area below the second branch pipe 220 where the blower nozzle 111 is located. During operation, the blower nozzle 111 should be located within this area to ensure the flow of air within the tee connector 200, thereby achieving cleaning.

[0032] It should be noted that the limiting tube 120 is fixed to the outside of the blow gun barrel 110 by the locking fastener 130. In use, the relative position of the limiting tube 120 and the blow gun barrel 110 is adjusted by tightening or loosening the locking fastener 130 so that the blow gun nozzle 111 reaches the area corresponding to the second branch tube 220.

[0033] Specifically, since the limiting tube 120 and the blower tube 110 are tubular structures extending in a single direction, in order to improve the stability of the vacuuming device structure, at least two locking fasteners 130 are distributed and connected on the limiting tube 120 along its extension direction. In this embodiment, the locking fastener 130 is a clamp that simultaneously achieves locking at two locations.

[0034] Example 2: This embodiment further optimizes the vacuuming device based on Embodiment 1. For similarities, please refer to [the original document / reference]. Figures 1 to 2 .

[0035] The optimizations in this embodiment are described below; please refer to the references. Figures 3 to 5 .

[0036] To optimize cleaning performance, the blower gun 110 includes a main blower section 112 and a blower gun section 113. The blower gun section 113 is inclined away from the main blower section 112, away from the second branch pipe 220. During operation, dust and other impurities enter the three-way connector 200 from the suction port 221 and are discharged from the dust collection port 231. During this process, the airflow may come into contact with the blower gun 110 located below the second branch pipe 220. At this time, the inclination of the blower gun section 113 away from the second branch pipe 220 helps to guide the airflow, ensuring that the airflow is smoothly directed towards the dust collection port 231, thus optimizing the cleaning effect.

[0037] Similarly, to improve airflow, the nozzle 111 is preferably located on the central axis of the second branch pipe 220. For example... Figure 4 and Figure 5 As shown, if the blower nozzle 111 crosses the central axis of the second branch pipe 220, the space between the blower tube 110 and the inner wall of the three-way connector 200 will shrink, resulting in poor airflow or affecting the removal of large-diameter impurities. If the blower nozzle 111 is away from the dust collection port 231 and far from the central axis of the second branch pipe 220, the negative pressure effect will worsen with increasing distance, and may even lead to the absence of a negative pressure zone. This will cause the airflow direction inside the three-way connector 200 to change, and the airflow blown out by the blower nozzle 111 will move towards the dust collection port 231 and the suction port 221 respectively, resulting in a loss of cleaning effect. Therefore, the best cleaning effect can be obtained when the blower nozzle 111 is located on the central axis of the second branch pipe 220.

[0038] It should be noted that the tee connector 200 can be a T-type tee connector, a Y-type tee connector, or other tee connectors. In this embodiment, the tee connector 200 is preferably a T-type tee connector 200, that is, the central axis of the second branch pipe 220 is perpendicular to the central axis of the first branch pipe 210 and the third branch pipe 230. At this time, the negative pressure generated is the strongest, which helps to improve the cleaning efficiency.

[0039] Example 3: This embodiment provides a vacuuming device, which is based on Embodiment 1. Please refer to the following: Figure 1 and Figure 2The vacuum cleaner includes a blower gun 100 and a three-way connector 200. The blower gun 100 has a blower tube 110, with a blower nozzle 111 at one end. When the blower gun 100 operates, it blows air along the blower tube 110 and out through the blower nozzle 111. The three-way connector 200 has a first branch tube 210, a second branch tube 220, and a third branch tube 230, which are interconnected. The first branch tube 210 is connected to the blower tube 110, and the blower nozzle 111 is located inside the three-way connector 200, specifically within the axially extending region of the hollow structure of the second branch tube 220. The second branch tube 220 has a suction port 221, and the third branch tube 230 is connected to a dust collection port 231. Specifically, the first branch pipe 210 and the third branch pipe 230 are coaxially arranged, with the dust-blowing nozzle 111 facing the third branch pipe 230, i.e., the dust collection port 231. A limiting tube 120 is movably sleeved around the dust-blowing tube 110, and the limiting tube 120 is fixed to the outside of the dust-blowing tube 110 by a locking fastener 130. For other similarities, please refer to Embodiment 1.

[0040] The differences are explained below; please refer to the references. Figures 6 to 7 .

[0041] Specifically, the suction port 221 is connected to a suction assembly 300, which is used to better reach the product to be cleaned for thorough cleaning. The dust collection port 231 is connected to a dust collection assembly 400, which is used to collect impurities.

[0042] Specifically, the vacuum assembly 300 includes a vacuum tube 310 and a vacuum nozzle 320 located at the end of the vacuum tube 310. One end of the vacuum tube 310 is connected to the vacuum port 221 of the second branch tube 220. The vacuum tube 310 can be connected to the vacuum port 221 via a threaded connection, a clamp connection, or by adding a sealing element to achieve an interference fit, etc. No specific limitations are made here. The other end of the vacuum tube 310 is connected to the vacuum nozzle 320. In particular, in this embodiment, the vacuum nozzle 320 includes annularly distributed comb teeth 321. The annular comb teeth 321 help clean fibrous impurities and prevent fiber blockage. In addition, the annular comb teeth 321 help reduce airflow diffusion, making the suction more concentrated.

[0043] Furthermore, the dust collection assembly 400 includes a dust collection pipe 410 and a dust collector 420 located at the end of the dust collection pipe 410. One end of the dust collection pipe 410 is connected to the dust collection port 231 of the third branch pipe 230. Similarly, the dust collection pipe 410 can be connected to the dust collection port 231 by means of threaded connection, clamp connection, or by adding a sealing element to achieve an interference fit, etc. No specific limitation is made here. The other end of the dust collection pipe 410 is connected to the dust collector 420 for collecting and storing dust to ensure the cleanliness of the environment during the cleaning process.

[0044] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
