Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the welding exhaust fan includes a housing 1, and a fan 2 and a light emitting unit 3 are integrated on the housing 1.

The fan 2 includes blades and a motor (not shown), wherein the motor is used for driving the blades to rotate, so as to form an air flow for blowing away or sucking smoke generated in the welding process, so that a worker can observe the condition of the welding point more clearly.

Wherein the light emitting unit 3 is also provided on the housing 1 for illuminating the surrounding environment so that the worker can more clearly observe the welding point. Especially, when the welding exhaust fan is too close to the product to be welded, the welding exhaust fan can shield an external light source, and at this time, the light-emitting unit 3 on the housing 1 can illuminate the product to be welded, so that a worker can clearly observe the welding point.

A protective screen 8 is further arranged on one side of the fan 2 facing the welding point to prevent hands and other parts of a welder from touching the fan 2 to cause injury.

As shown in fig. 2, the side of the casing 1 facing the products to be welded is also provided with a flared opening, so as to improve the smoke evacuation effect.

As shown in fig. 1, the smoke sensor 4 is further provided on the housing 1, and the smoke sensor 4 is connected to a motor (not shown). The smoke sensor 4 may use a structure conventional in the art, and is intended to detect the smoke concentration of the surrounding environment, so as to adjust the power of the motor and thus the rotation speed of the fan blades. When the smoke concentration is detected to be high in the welding process, the wind power of the exhaust fan is automatically increased, and when the smoke concentration is detected to be low, the wind power of the exhaust fan is weakened.

The light emitting unit 3 of the present embodiment is an LED lamp, which not only saves energy, but also has high illumination brightness. Of course, the lighting unit 3 may also be any other lighting element conventional in the art, such as a fluorescent lamp, an incandescent lamp, etc.

The present example also provides a light dependent resistor 5 on the housing 1, the light dependent resistor 5 being connected to the light emitting unit 3 for adjusting the light of the light emitting unit 3. The brightness of the light emitting unit 3 can be automatically adjusted according to the intensity of the ambient light.

The smoke sensor 4 and the photoresistor 5 are arranged, so that the welding exhaust fan is more energy-saving, and the welding operation of workers is facilitated. The phenomenon that the smoke concentration is too high and the wind power is small can not occur, and the phenomenon that the smoke concentration is too low and the wind power is large and noise is generated can not occur. The situation that the welding point cannot be observed clearly due to insufficient brightness does not occur, and the situation that the welding point cannot be observed too much and dazzling cannot occur.

As shown in fig. 1 and 2, a power switch i 9 and a power switch ii 10 disposed on the housing 1 are respectively used for controlling power on/off of the fan 2 and the light emitting unit 3, and the power switch i 9 and the power switch ii 10 are independent from each other, that is, the power on/off of the fan 2 and the light emitting unit 3 are independent from each other, so that the fan 2 or the light emitting unit 3 can be selectively turned on according to the situation, and the adaptability is wider. For example, the lighting device is suitable for the condition that only the fan 2 is turned on, such as the external illumination is sufficient in the daytime; for example, the lighting device is suitable for the condition that only the light-emitting unit 3 is turned on, such as the welding operation is finished, the fan 2 is turned off, and the lighting function is still needed.

As shown in fig. 1 and 2, the top of the casing 1 is also provided with a handle 7 for facilitating lifting and moving welding of the exhaust fan. Of course, the position of the handle 7 is not particularly limited, and may be provided on the side of the housing 1, for example.

As shown in fig. 1 and 2, the bottom of the housing 1 is further provided with a stabilizing bracket 6 to facilitate stable placement of the welding exhaust fan on different platforms.

In summary, the welding exhaust fan of the present embodiment, because the fan 2 and the light emitting unit 3 are integrated on the same housing 1, avoids the embarrassment problem that the welding exhaust fan cannot smoke well too far away from the product and cannot shade light too close to the product.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
