Description

Oxygen fan

The present invention relates to a fan (electric fan), in particular to a fan that can prevent the safety of choking often caused by a commonly used fan.

A fan is a device that attaches wings to the shaft of an electric motor and generates wind by its rotation, and is used in hot summers or places where the temperature is high because it can cool the surroundings by heat exchange caused by wind. In particular, since the power consumption is relatively low compared to the air conditioner is widely used in homes or industrial sites.

In general, the structure of the fan is provided with a hollow support member in the main body in which the display unit is built, and the support member protrudes and extends the height adjustable inside the support member. A motor having a mechanism device rotatable at an angle is installed at the end of the protruding support according to the input value of the rotation angle input from the display, and a fan is connected to the shaft of the motor. In addition, a safety net is installed around the fan to prevent a safety accident.

When the fan is operated, the motor and the apparatus are controlled by the wind strength or the wind direction input from the display unit and the timer to generate the wind.

However, as is well known, when people fall into a state of sleep in a confined space for a long time while blowing the fan's wind, the thermoregulation function is paralyzed and dangerous situations or suffocation often occur and lose valuable lives.

The present invention aims to provide a fan that can prevent choking in order to solve these problems.

In order to achieve the above object, the present invention is to install a support on the main body equipped with a display unit, and in the fan for transmitting the wind using a motor coupled to the support, it is installed on the main body is inserted into the support A support member which forms a hollow portion, a protrusion is formed on the inner side, and two guide grooves having different diameters are formed successively from the tip of the protrusion to the inside, and a through hole is formed from the center of the inner guide groove to the outside.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, a hollow support member 14 is installed on the main body 10 having the display unit 12 therein, and the support member 14, which is capable of height adjustment, protrudes and extends to the support member 14. A stopper 18 is installed at the tip of the member 14 to adjust the height of the support 16.

In addition, a motor 20 having a mechanism device rotatable by a predetermined angle is installed at an end of the protruding support 16 in accordance with an input value of the rotation angle input from the display unit 12. 22) is connected. In addition, the safety net 24 for covering a safety accident is covered around the fan 22.

In order to realize the fan according to the present invention, the support member 50 is formed so that a space for mounting the oxygen storage can 26 (hereinafter referred to as an oxygen can) is provided during the initial manufacture of the support member 14.

An approximately square insertion hole 51 is formed over the entire surface of the supporting member 50, and a door 100 having a size corresponding to the insertion hole 51 is provided, and the lower inner leading end of the insertion hole 51 is provided. To the hinge 102. Then, the locking device 104 is installed in the door 100 to prevent the oxygen can 26 mounted inside the support member 50 from being separated.

On the other hand, as shown in Figure 2a specifically showing the configuration of the portion A in Fig. 1 to form a through hole 52 in a portion of the support member 50, the center of the support member 50 of the through hole 52 On the inner side, a protrusion 55 having a substantially cylindrical shape is formed. The protrusion 55 has two guide grooves 57 having different diameters in the inward direction from the tip portion thereof, and thus has a guide jaw 59. On the inner bottom surface of the guide groove 57, a plurality of cams 58 having a predetermined slope are formed in the circumferential direction.

And it is inserted into the through-hole 52 of the support member 50 is provided with a rotary key 60 which has an axis to protrude inwardly and rotate in the forward and reverse directions. It is coupled to the axis of the rotary key 60 and is provided with a substantially cylindrical rotary boss 70 that moves forward and backward in the axial direction according to the forward and reverse rotation of the rotary key 60 is inserted into the protrusion (55).

In particular, one end of the rotary boss 70 has an inclination corresponding to the cam 58, and the other tip is formed with two grooves 72 having different diameters inward, and the rotary boss is formed at the end of the inner groove. The tunnel 73 penetrates to the outer circumferential surface of the 70 so that the oxygen flowing out of the oxygen can 26 reaches the outer circumferential surface of the rotary boss 70. In addition, a gasket 74 is provided in the outer groove to prevent the oxygen flowing out through the oxygen can 26 from leaking out of the tunnel.

In addition, a flange 76 is formed on the outer circumferential surface of the rotary boss 70 so as to face the guide jaw 59 of the protrusion 55.

In order to prevent the rotary boss 70 from being separated from the guide groove 57 when the rotary boss 70 moves forward and backward, a support plate 80 having an inner diameter slightly larger than the diameter of the rotary boss 70 is installed at the tip of the protrusion 55. In addition, a spring 85 is installed between the support plate 80 and the flange 76 of the rotary boss 70 to elastically bias the rotary boss 70 that interlocks with each other.

On the other hand, it is provided with a flexible tube 90, one side is connected to the tunnel 73 of the rotary boss 70, the other side is installed through the hollow support member 14 to be installed in the rear portion of the fan 22.

In the process of supplying oxygen in the fan of the present invention having such a structure, the door 100 is opened, the oxygen can 26 is inserted into the insertion hole 51, and the door 100 is locked by the locking device 104. .

Subsequently, as shown in FIG. 2B, when the rotary key 60 is rotated in the forward direction, the inner groove of the rotary boss 70 is oxygen can while the flange 59 of the rotary boss 70 pressurizes the spring 85. Pressure is applied to the oxygen outlet at (26). Oxygen then flows out of the oxygen can 26 and is discharged through the tunnel 73 and the tube 90 to the rear of the fan 22. The oxygen released in this way is ejected into the room in the rotating fan (22). In order to prevent the outflow of oxygen, the rotary key 60 may be replaced.

As described above, the fan capable of supplying oxygen according to the present invention is supplied with oxygen from an oxygen can when using a fan, thereby preventing the safety accident of asphyxiation when taking a sleep in an enclosed space or a work space.
