Detailed Implementation

[0034] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0035] The inventors of this application have discovered that existing technologies have problems such as the inability to adjust the gas flow rate and vacuum pressure of the suction gun, and high air consumption. Based on these problems, this utility model provides a handheld energy-saving suction gun, with reference to... Figure 1 As shown, the handheld energy-saving wire suction gun specifically includes:

[0036] The components are connected in sequence: a suction tube 6, a vacuum generator assembly, and a waste filament collection bag 2; the vacuum generator assembly includes a vacuum generator 1; the vacuum generator 1 includes a suction nozzle 12 and a vacuum generator body 11; the waste filament collection bag 2 is connected to the vacuum generator body 11.

[0037] The vacuum generator body 11 has an air supply port on its side wall for connecting to an external air source. The suction nozzle 12 is sleeved on the vacuum generator body 11 by an adjusting bolt 14 and communicates with the inside of the vacuum generator body 11. When the adjusting bolt 14 is loose, the suction nozzle 12 can move axially to change the size of the air supply port opening.

[0038] The handheld energy-saving wire suction gun provided by this utility model allows the suction nozzle 12 to move axially by loosening the adjusting bolt 14, thereby adjusting the size of the air supply port formed by the connection between the suction nozzle 12 and the vacuum generator body 11. This, in turn, adjusts the intake gas flow rate and vacuum pressure. The handheld energy-saving wire suction gun has a simple structure and is easy to operate, effectively improving the efficiency of waste wire suction. Furthermore, by incorporating a waste wire collection bag, the handheld energy-saving wire suction gun can directly suction and collect waste wire, resulting in a well-integrated product.

[0039] Reference Figure 2 and Figure 3 As shown, the vacuum generator body 11 has an air supply port (SUP) on its side wall, the outer end of the suction nozzle 12 is an air inlet 51 (VAC), and the other end of the vacuum generator body 11 is an outlet (EXH), which is used to discharge waste filaments and gas. A transverse channel is formed inside the vacuum generator 1, and the connection between the vacuum generator body 11 and the suction nozzle 12 forms a narrow channel.

[0040] In practical implementation, while the suction nozzle 12 and the vacuum generator body 11 are connected by adjusting bolts 14, the outer wall of the suction nozzle 12 and the vacuum generator body 11 can also be threaded together. The location of the threaded connection is as follows: Figure 2As shown, after loosening the adjusting bolt 14, the suction nozzle 12 can be moved axially by rotating it, for example:

[0041] Rotating the suction nozzle 12 clockwise on the side facing it causes it to move inward along the axial direction. This reduces the size of the opening formed between the suction nozzle 12 and the vacuum generator body 11 at the air supply port, resulting in a smaller gas flow rate and a lower vacuum pressure. Rotating the suction nozzle 12 counterclockwise on the side facing it causes it to move outward along the axial direction. This increases the size of the opening formed between the suction nozzle 12 and the vacuum generator body 11 at the air supply port, resulting in a larger gas flow rate and a higher vacuum pressure.

[0042] In one embodiment, the nozzle 12 and the vacuum generator body 11 are sealed by a sealing ring 13.

[0043] In one embodiment, the vacuum generator assembly further includes: a cylinder 3;

[0044] One end of the cylinder 3 is connected to the suction tube 6, and the other end of the cylinder 3 is sleeved with the vacuum generator body 11, with the suction nozzle 12 facing inwards from the cylinder 3, and the tail of the vacuum generator body 11 outside the cylinder 3.

[0045] In practice, the tail of the vacuum generator body 11 is connected to the waste filament collection bag 2.

[0046] In one embodiment, the vacuum generator assembly further includes: a front cover 5; the front cover 5 is disposed at the waste wire inlet of the vacuum generator 1 and connected to the wire suction tube 6; the front cover 5 has multiple air inlets. In specific implementations, refer to... Figure 4 As shown, multiple air inlets are evenly distributed on the front cover 5. These multiple air inlets are used to draw in external air to increase the air intake, thereby increasing the gas flow and vacuum pressure inside the vacuum generator 1, so that less air is needed under the same suction force, thus saving more air and energy.

[0047] In one embodiment, the above-mentioned handheld energy-saving wire suction gun further includes: an opening fixing ring 7; the opening fixing ring 7 is disposed on the front outer wall of the front cover 5, and the wire suction tube 6 passes through the ring hole of the opening fixing ring 7 and the front cover 5 in sequence and extends into the vacuum generator 1; a vertical axial threaded through hole is provided on the outer ring side wall of the opening fixing ring 7, and the bolt that mates with the threaded through hole is loosened or tightened to adjust the opening tightness of the opening fixing ring 7.

[0048] After loosening the bolts of the opening fixing ring 7, the opening of the opening fixing ring 7 becomes loose. By moving the suction tube 6 back and forth, the position of the suction tube 6 extending into the vacuum generator 1 can be changed, thereby fine-tuning the vacuum pressure at the inlet of the suction tube 6.

[0049] In one embodiment, the vacuum generator assembly further includes a rear cover 4; the rear cover 4 is disposed at the waste filament outlet of the vacuum generator body 11.

[0050] In one embodiment, the vacuum generator assembly further includes a quick-connect connector 9; one end of the quick-connect connector 9 is connected to the air supply port, and the other end is used to connect to an external air source. The quick-connect connector 9 allows for rapid and effortless insertion and removal, effectively saving time and improving worker efficiency.

[0051] In one embodiment, the aforementioned handheld energy-saving wire suction gun further includes a plastic sheath 8; the plastic sheath 8 is disposed at the inlet of the wire suction tube 6. The plastic sheath 8 serves to prevent static electricity and protect the handheld energy-saving wire suction gun from direct contact with other external equipment, and the plastic sheath 8 can be directly removed and replaced when worn.

[0052] In one embodiment, the outer wall of the cylinder 3 is provided with an annular groove. This annular groove is suitable for gripping, making it easy to hold and less likely to slip out of the hand.

[0053] In one embodiment, the aforementioned handheld energy-saving wire suction gun further includes: a clamp; the outlet of the vacuum generator 1 is connected to the waste wire collection bag 2 via the clamp. The outlet of the vacuum generator 1 is fixed to the waste wire collection bag 2 via the clamp. The waste wire collection bag 2 is used to collect waste wire. Compared with manually tying the waste wire collection bag 2 with rope, fixing the waste wire collection bag 2 with the clamp is more efficient, aesthetically pleasing, and convenient for replacement.

[0054] In one embodiment, the vacuum generator body is flared at the connection point with the suction nozzle; the connection between the vacuum generator body and the suction nozzle forms a narrow channel. Generally, the vacuum pressure is highest near the narrow opening where the vacuum generator body 11 connects to the suction nozzle 12, meaning the closer to this location, the higher the wire suction efficiency. Therefore, in practical implementation, the wire suction tube 6 can be inserted into the narrow channel at the connection point between the vacuum generator body 11 and the suction nozzle 12 to obtain a greater vacuum pressure, thereby improving the wire suction efficiency.

[0055] The following is a specific example illustrating the working process of the handheld energy-saving wire suction gun provided by this utility model:

[0056] Action 1: The external air source is connected to the quick-connect connector 9 and supplies air. After the air enters the air supply port of the vacuum generator 1, it enters the transverse channel of the vacuum generator 1 through the narrow channel connecting the vacuum generator body 11 and the suction nozzle 12.

[0057] Action 2: Due to the rapid change in airflow velocity, a negative pressure is generated at the narrow channel connecting the vacuum generator body 11 and the nozzle 12. The air inlet of the front cover 5 draws in a large amount of external air, which is discharged from the outlet along with the gas supplied by the air supply port.

[0058] Action 3: Under the action of airflow, the waste filament sucked into the suction tube 6, along with the air, is discharged into the waste filament collection bag 2 by the vacuum generator 1.

[0059] Action 4: In this example, the vacuum generator body 11 and the suction nozzle 12 are also connected by threads. When the gas flow rate or vacuum pressure is low, the suction nozzle 12 is rotated counterclockwise facing the suction nozzle 12 to increase the gas flow rate and thus increase the vacuum pressure. Similarly, when the gas flow rate or vacuum pressure is high, the suction nozzle 12 can be rotated clockwise facing the suction nozzle 12 to reduce the gas flow rate and thus reduce the vacuum pressure.

[0060] Action 5: After loosening the bolts of the opening fixing ring 7, move the suction tube 6 back and forth to change the position of the suction tube 6 extending into the vacuum generator 1, and also to fine-tune the vacuum pressure at the inlet of the suction tube 6. Since the vacuum pressure is greatest near the narrow channel connecting the vacuum generator body 11 and the suction nozzle 12, the closer the suction tube 6 is to this position, the higher the suction efficiency.

[0061] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
