Technical Field
[0001] This utility model relates to the field of dust removal device technology, and in particular to a dust removal device for electronic product repair. Background Technology
[0002] Electronic products often accumulate a lot of dust during use, especially electronic devices that need to maintain communication with the outside world. These devices need to be cleaned during maintenance.
[0003] A search revealed, for example, a dust removal device for electronic product repair provided by patent publication number CN109332247A, comprising a housing, a horizontal partition fixedly connected to the middle of the inner side of the housing, a motor bracket fixedly connected to the upper right side of the horizontal partition, a motor fixedly connected to the upper part of the motor bracket, a driving bevel gear fixedly connected to the middle of the motor output end, a longitudinal shaft rotatably connected to the middle of the horizontal partition, a driven bevel gear fixedly connected to the top of the longitudinal shaft, the driven bevel gear meshing with the driving bevel gear, a longitudinal fan fixedly connected to the upper part of the longitudinal shaft, a driving gear fixedly connected to the lower part of the longitudinal shaft, and a bearing seat rotatably connected to the upper part of the driving gear. During use, this device can effectively clean and remove dust from electronic equipment.
[0004] Based on the above search and the findings of existing technologies, existing dust removal devices similar to those disclosed above have brushes of fixed shape and size, which is inconvenient for cleaning different areas of electronic products. For example, larger brushes are not suitable for cleaning dust in relatively small areas, while smaller brushes result in slower dust removal when cleaning relatively large flat areas. Therefore, an electronic product repair dust removal device is proposed to improve the above-mentioned problems. Utility Model Content
[0005] The purpose of this application is to provide an electronic product repair and dust removal device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this application provides the following technical solution: an electronic product repair and dust removal device, including a vacuum fan and a vacuuming part installed at the vacuuming end of the vacuum fan via a connecting part. The vacuuming part includes a main vacuum pipe and multiple brushes. The main vacuum pipe is connected to the connecting part, and the multiple brushes are all installed at the end of the main vacuum pipe away from the connecting part.
[0007] The brush includes a secondary suction pipe and cleaning bristles. One end of the secondary suction pipe is hinged to the main suction pipe, and the secondary suction pipe is fixedly connected to the main suction pipe through a flexible tube. The secondary suction pipe has multiple suction holes equidistantly arranged along its own axis. Multiple cleaning bristles are fixed equidistantly at the side end of the secondary suction pipe, and the cleaning bristles and suction holes are distributed alternately.
[0008] The main suction pipe is connected to an adjustable limiting sleeve that limits the movement of multiple auxiliary suction pipes.
[0009] In the aforementioned electronic product repair and dust removal device, the main suction pipe, adjustable limit sleeve, and multiple brushes are arranged in a coordinated manner. The adjustable limit sleeve can be used to adjust the extent of the spread of multiple brushes according to the size of the actual dust removal area, thereby improving the versatility of the dust removal device.
[0010] As a further supplement to this solution, an adjustable limiting sleeve is threaded onto the outside of the main vacuum tube, and the main vacuum tube can be simultaneously fitted onto the outside of multiple auxiliary vacuum tubes. A torsion spring is connected between the auxiliary vacuum tubes and the main vacuum tube, and the torsion spring causes the auxiliary vacuum tubes to expand outward.
[0011] As a further supplement to this solution, the adjustable limiting sleeve has multiple grooves equidistantly arranged parallel to its own axis.
[0012] As a further supplement to this solution, a mounting plate is fixed to the end of the main suction pipe near the connecting part. The lower end of the mounting plate is hinged to a limiting rod. The end of the limiting rod away from the connecting part is adapted to any groove. A torsion spring is connected between the limiting rod and the connecting part. The torsion spring causes the limiting rod to approach the adjustable limiting sleeve.
[0013] As a further supplement to this solution, a power air hole is provided at the end of the main suction pipe located inside the connecting part, and the axis of the power air hole does not intersect with the axis of the main suction pipe, and the main suction pipe is rotatably connected to the connecting part.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example: Reference Figure 1-4 The device shown is an electronic product repair and dust removal device, including a vacuum fan 1 and a dust collection part installed on the vacuum end of the vacuum fan 1 via a connecting part 2. The vacuum fan 1 can be a conventional model, such as a fan of model 2HB710-AH26, and is electrically connected to a controller using conventional technical means to control the opening and closing of the vacuum fan 1. The dust collection part includes a main suction pipe 3 and multiple brushes. The main suction pipe 3 is connected to the connecting part 2, and the multiple brushes are installed at the end of the main suction pipe 3 away from the connecting part 2.
[0027] The brush includes a secondary suction pipe 4 and cleaning bristles 5. One end of the secondary suction pipe 4 is hinged to the main suction pipe 3, and the secondary suction pipe 4 is fixedly connected to the main suction pipe 3 through a flexible hose 12. The secondary suction pipe 4 has multiple suction holes 401 equidistantly arranged along its own axis. Multiple cleaning bristles 5 are fixed at equal intervals to the side end of the secondary suction pipe 4, and the cleaning bristles 5 and suction holes 401 are staggered. An adjustable limiting sleeve 6 is connected to the main suction pipe 3 to limit the multiple secondary suction pipes 4. Specifically, the adjustable limiting sleeve 6 is threaded onto the outside of the main suction pipe 3, and the main suction pipe 3 can be simultaneously fitted onto the outside of multiple secondary suction pipes 4. A torsion spring is connected between the secondary suction pipe 4 and the main suction pipe 3, and the torsion spring causes the secondary suction pipe 4 to unfold outward.
[0028] Based on the aforementioned arrangement of the main suction pipe 3, adjustable limiting sleeve 6, and multiple brushes, the adjustable limiting sleeve 6 allows for adjustment of the spread of the multiple brushes according to the actual size of the area to be cleaned. For example... Figure 1 and Figure 2 Two of the usage states are shown.
[0029] The adjustable limiting sleeve 6 has multiple grooves 601 arranged at equal intervals parallel to its own axis, which makes it convenient for operators to rotate the adjustable limiting sleeve 6 to adjust the unfolding degree of multiple brushes.
[0030] In addition, to prevent the adjustable limiting sleeve 6 from rotating unintentionally, a mounting plate 13 is fixed to the end of the main suction pipe 3 near the connecting part 2. The lower end of the mounting plate 13 is hinged to a limiting rod 7. The end of the limiting rod 7 away from the connecting part 2 is adapted to any groove 601. A torsion spring 2 is connected between the limiting rod 7 and the connecting part 2. The torsion spring 2 causes the limiting rod 7 to approach the adjustable limiting sleeve 6. After the adjustable limiting sleeve 6 is adjusted, the limiting rod 7 is engaged in any groove 601 under the action of the torsion spring 2, thereby achieving relative fixation between the adjustable limiting sleeve 6 and the main suction pipe 3.
[0031] The main suction pipe 3 is provided with a power air hole 301 at the end located inside the connecting part 2. The axis of the power air hole 301 does not intersect with the axis of the main suction pipe 3. The main suction pipe 3 is rotatably connected to the connecting part 2. When the airflow mixed with dust passes through the power air hole 301, the reverse thrust causes the main suction pipe 3 to rotate with multiple brushes, thereby realizing the automatic cleaning function of the brushes on the dust.
[0032] In addition, the connecting part 2 includes a fixed ring seat 21 and a connecting cylinder 22. The fixed ring seat 21 is fixedly connected to the vacuum blower 1. A filter hopper 8 is detachably installed on the inner side of the fixed ring seat 21. The connecting cylinder 22 is rotatably connected to the main vacuum pipe 3. The connecting cylinder 22 is detachably connected to the fixed ring seat 21. An elastic opening and closing piece 9 is provided at the position where the connecting cylinder 22 and the fixed ring seat 21 are connected. One edge of the elastic opening and closing piece 9 is fixed to the position where the connecting cylinder 22 and the fixed ring seat 21 are connected. During vacuuming, the elastic opening and closing piece 9 opens under the action of airflow. After vacuuming, the elastic opening and closing piece 9 closes under its own elasticity to prevent the dust in the filter hopper 8 from falling back into the main vacuum pipe 3.
[0033] The filter hopper 8 is provided with a cleaning frame 11 on the side near the connecting cylinder 22. The cleaning frame 11 does not contact the filter hopper 8 to avoid scratching the filter hopper 8 and prevent damage to the filter hopper 8. The cleaning frame 11 is coaxially fixed with the main suction pipe 3 and the drive shaft 10. During the vacuuming process, the main suction pipe 3 drives the cleaning frame 11 to rotate through the drive shaft 10. The rotating cleaning frame 11 disturbs the dust attached to the surface of the filter hopper 8, preventing the dust from being statically attached too thickly and improving the vacuuming effect.
[0034] The working principle of this utility model is as follows: the degree of unfolding of multiple brushes is adjusted according to the size of the dust cleaning area as needed. Specifically, the limiting lever 7 is opened and the adjustable limiting sleeve 6 is rotated. For example, rotating in the forward direction causes the adjustable limiting sleeve 6 to move down, causing multiple brushes to tend to shrink. Rotating in the reverse direction causes the adjustable limiting sleeve 6 to move up, causing multiple brushes to gradually unfold under the action of the torsion spring.
[0035] After adjusting the adjustable limit sleeve 6, loosen the limit lever 7. Under the action of the torsion spring 2, the limit lever 7 will be inserted into any of the grooves 601 (it can be manually fine-tuned here so that the nearest groove 601 matches the limit lever 7), thus achieving relative fixation between the adjustable limit sleeve 6 and the main suction pipe 3. After that, start the vacuum fan 1 to perform the dust removal function.
[0036] It should be noted that the specific model and specifications of the controller and vacuum fan 1 in this solution need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here. Furthermore, the power supply and principle of the controller and vacuum fan 1 are clear to those skilled in the art, and will not be described in detail here.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
