The head part 10 is held by a freely-bendable flexible tube 11, and an angle of a dust collection surface 27 and a distance to a work part can be discretionarily set. Here, the "dust collection surface" refers to the disc-shaped surface that is parallel to a surface in the rotating direction of an electric fan, the center of which is a center of the electric fan, and the radius of which is a movable radius of the fan. An AC adapter 13 or a battery is used as a power supply for the electric fan.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to an industrial dust collecting device. [Background technology]

[0002] Industrial dust collectors are devices that use an electric suction fan to suck in fumes and other substances that may be harmful to humans during soldering or welding work, and then remove particles using a dust collection filter. Horizontally installed and ducted types are the most commonly used types. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jikko Showa 51-14452 [Patent Document 2] Jikkai Showa 53-52653 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned Patent Document 1, the dust collection surface can only be set to move in one axis in the vertical direction, which limits the setting to ensure sufficient suction without obstructing the field of view. Also, because a light bulb is used for the lighting section, the suction section becomes narrow, making it difficult to achieve a sufficient dust collection effect.

[0005] In Non-Patent Document 2, the air conditioner is mainly intended for use in a kitchen, so the exhaust pipe is generally long and handling must be considered, which means that the installation is not compact.

[0006] Conventional industrial dust collectors for smoke generated by soldering, welding, etc., are divided into two types: portable types that are installed next to the work area (hereinafter simply referred to as "horizontal installation type"), and types that use large fans installed on walls, etc., with ventilation piping extended to directly above the work area to collect dust (hereinafter simply referred to as "duct type").

[0007] In horizontally installed industrial dust collectors, smoke usually moves from the bottom to the top, so it cannot be sucked in sufficiently, and the smoke gets into the workers, which increases the possibility of it affecting the human body if they work there for many years.In order to increase the suction power, it is necessary to increase the output of the electric fan inside the device, but in that case the fan noise will increase, the device itself will become larger, and it will need to be installed in a larger space, so using a large fan like a ventilation fan is not practical.

[0008] Duct systems are typically used to collect smoke and dust from soldering work, but they require extensive construction work, such as the installation of large electric fans and ventilation piping. Once installed, these systems often require rework when changing the layout of the work site, making it difficult to quickly add additional soldering workers. Additionally, soldering work is often expanded from assembly plants to home-based work, and in these cases, industrial dust collection equipment is often loaned, resulting in the use of horizontal-mounted systems with the aforementioned suction power issues, making it difficult to rent duct systems. Duct systems require a fixed line of sight even when the worker's seating height changes. Low ducts raise the worker's line of sight, making them a hindrance for some workers, while high ducts result in insufficient dust collection. Increasing the duct diameter to increase suction power creates shadows in the work area, making the work area darker and increasing the risk of defective products, especially when performing delicate soldering.

[0009] In recent years, cell work, a method in which one person performs tasks such as soldering and screwing, and completes the product, has become widely used in production sites for home appliances, etc. In the traditional division of labor system, a soldering worker would only perform soldering work, but in production sites for a wide variety of small lots, it is necessary to perform tasks other than soldering, and in this case, since ventilation piping gets in the way, it becomes necessary to set up a separate work area for screwing and other tasks.

[0010] In addition, with the duct type, the ventilation pipes are placed over the work area, making the work area dark and potentially resulting in defective products when soldering finely, so a light must be installed from the side. [Means for solving the problem]

[0011] The industrial dust collector of the present invention has a head with a built-in suction electric fan and dust collection filter, and the head is attached to the tip of a flexible tube that can be freely bent and held, and the distance from a disk-shaped surface (dust collection surface) that is parallel to the plane of the electric fan's rotation direction, centered on the center of the fan, and has a radius equal to the electric fan's movable radius, or from an object such as solder, can be set as desired.Furthermore, it is characterized by having a fixing part such as a magnet or clamp on the opposite side of the head, and using an AC adapter or battery for power. Furthermore, a flexible tube is connected to the side wall of the head that surrounds the electric fan. [Effects of the Invention]

[0012] The present invention allows the use of a small-output electric fan, making it compact and quiet, and does not take up much space during or after use. It also saves power, making it usable in places with limited power supply capacity. [Brief explanation of the drawings]

[Figure 2] Composition of the dust collection surface [Figure 3] A component inside the head of the industrial dust collector of the present invention. [Figure 4] Configuration of the head of the industrial dust collector of the present invention DETAILED DESCRIPTION OF THE INVENTION

[0014] As shown in Figure 1, the present invention has a head 10 with a built-in suction fan 20. The head is equipped with a compact yet powerful lighting unit 25, such as an LED or organic electroluminescent (EL) light source. The head 10 is held by a flexible tube 11, which can be manipulated to freely adjust the fan's dust collection surface 27. Here, the term "dust collection surface" refers to a disk-shaped surface parallel to the direction of fan rotation, centered on the center of the fan, and with a radius equal to the fan's rotational radius. Power to the fan 20 is supplied from a commercial power source using an AC adapter 13. A magnetic or other type of base is used to secure the flexible tube 11. In addition to commercial power, batteries or other power sources can also be used.

[0015] The inside of the dust collector head is composed of an electric dust-collecting fan 20 for suction, a dust-collecting filter 22 that removes floating materials such as solder fumes, a fan guard 21 that prevents the user's hands from coming into direct contact with the fan blades for safety, a lighting unit 25, and a power switch 26. If necessary, the fan guard 21 can be omitted. The lighting unit is composed of a circuit board 23, an LED 24 that is a mounted component, and other electronic components. The power supply can be built into the head or attached to a fixed part, in which case it will be a type with an outlet cord. [Explanation of symbols]
