Description

A portable exhaust fan

technical field

The utility model relates to a kitchen exhaust fan, in particular to an exhaust fan which is easy to carry and install.

Background technique

At present, household exhaust fans on the market need to be fixedly installed during use, and the relative position and distance between the exhaust fan and the induction cooker cannot be well adjusted, which brings great inconvenience to users. Especially for some users whose residences change frequently, they hope to use an exhaust fan that is more convenient in terms of disassembly, installation and portability.

Contents of the invention

In order to overcome the inconvenience of the exhaust fans currently on the market in terms of disassembly and assembly and adjustment of the relative position between the exhaust fan and the induction cooker, the utility model provides a portable exhaust fan that is easy to disassemble and flexible to use.

The technical scheme of the utility model is: a portable exhaust fan of the utility model, including the exhaust fan, and also includes a telescopic folding fixing device, the telescopic folding fixing device consists of a fixing piece with a round hole, an upper telescopic strip, a lower telescopic strip and Composed of rotating shafts, the diameter of the circular hole is larger than the diameter of the foot pad of the induction cooker.

As a further improvement of the utility model, there are two telescopic folding fixing devices, each of which is composed of a fixing piece with a round hole, an upper telescopic strip, a lower telescopic strip and a rotating shaft; the diameter of the round hole is larger than that of the foot pad of the induction cooker .

As a further improvement of the utility model, the rotating shaft connects the lower telescopic bar and the upper telescopic bar, so that the angle between the two telescopic bars can be adjusted between 0° and 90°, and can be fixed at a certain angle; The bar and the upper telescopic bar are folded together through the rotating shaft to form an angle of 0°; when unfolded, the lower telescopic bar and the upper telescopic bar can form an angle between 0° and 90° through the rotating shaft.

As a further improvement of the utility model, the lower telescopic bar and the upper telescopic bar are sliding telescopic structures.

As a further improvement of the utility model, the upper telescopic strip is arranged on both sides of the exhaust fan; the right side of the exhaust fan is provided with a fixed head for fixing the position of the exhaust fan on the upper telescopic strip.

The beneficial effect of the utility model is that the user can conveniently carry and install the exhaust fan and adjust the relative position of the exhaust fan and the induction cooker as required due to the adoption of the telescopic folding and fixing structure.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Embodiment 1, with reference to Fig. 1, the portable exhaust fan comprises exhaust fan 9, also comprises two telescopic folding fixing devices, each all is made of fixing plate 1 with circular hole 2, upper telescopic bar 5, lower telescopic bar 3 and The rotating shaft 4 is formed; the diameter of the circular hole 2 is larger than the diameter of the pad of the induction cooker. The rotating shaft 4 connects the lower telescopic bar 3 and the upper telescopic bar 5, so that the angle between the two telescopic bars is adjustable between 0 and 90°, and can be fixed at a certain angle; when folding, the lower telescopic bar 3 and the upper telescopic bar 5 are folded together through the rotating shaft 4 to form an angle of 0°; when unfolded, the lower sliding bar 3 and the upper telescopic bar 5 can form an angle between 0° and 90° through the rotating shaft 4. The lower telescopic bar 3 and the upper telescopic bar 5 are sliding telescopic structures. The upper telescopic bar 5 is arranged on both sides of the exhaust fan 9; the right side of the exhaust fan 9 is provided with a fixed head 7 for fixing the position of the exhaust fan 9 on the upper telescopic bar 5. The top of the exhaust fan 9 is provided with a switch 8 for controlling the operation of the exhaust fan, and the plug 6 is used for accessing the power supply.

Figure 2 is a schematic diagram of the lower telescopic bar 3 and the upper telescopic bar 5 being fully stretched and fixed respectively. The user can adjust the length of the upper telescopic bar 5 and the lower telescopic bar 3 according to the needs, and fix the exhaust fan by adjusting the fixed head 7. 9 in height.

FIG. 3 is a schematic diagram of the lower telescopic bar 3 and the upper telescopic bar 5 being folded and folded through the rotating shaft 4 .

When using the exhaust fan, the user does not need to fix the exhaust fan on the wall or window, but only needs to nest the round hole 2 on the fixed piece 1 on the foot pad of the induction cooker, and slide and expand the lower telescopic bar according to the user's needs. 3, the height of the exhaust fan 9 is fixed by adjusting the fixed head 7. When the exhaust fan is not needed, only the lower telescopic bar 3 and the upper telescopic bar 5 need to be folded, and the exhaust fan can be folded up through the rotating shaft 4 and stored in a proper position.

The utility model is suitable for family use.
