Abstract

PURPOSE: A nozzle rotating device for a humidifier is provided to rotate a nozzle in the range from 0° to 360° as desired by a user, thereby humidifying a wide area in a short time. CONSTITUTION: A nozzle rotating device for a humidifier includes a semi-cylindrical case, wherein the case is integrally provided with a PCB(301) for driving a motor, a small sized pulse motor(302), a reduction gear unit(303), a rotation angle control gear(304), a rotation angle control pin(305), a rotation shaft(211), a high speed rotation on/off switch(212), a power on/off and angle control switch(213), and a power supply source(306). As the pulse motor is started to rotate, rotation force reduced to a low speed by the reduction gear set is transmitted to the rotation shaft, so that a rotation nozzle fixed in the rotation shaft is rotated.

Description

Mechanism device for rotating nozzle of humidifier {Humidifier's turning nozzle}

The spraying device rotating device of the humidifier is a method of attaching a motor to the humidifier body. The humidifier structure and the humidity of the humidifier, which must be supplemented with water, are frequently used. Due to its characteristics, it was difficult to commercialize and the cost of production increased.

Due to the nature of the humidifier, it is used continuously for a long time in a quiet room, while minimizing the noise of the motor when rotating the spray hole, and it is equipped with an electric device and a mechanical device, so it must be manufactured as a waterproof hole. It should be able to rotate and spray at the angle that user wants.

The present invention is embedded by placing the mechanism of the independent structure shown in Figure 2 in the discharge passage 101 of the conventional humidifier shown in Figure 1, as a power source of the main body or a separate power source, that is, using a battery Miniaturized for use, PCB board 301, small pulse motor 302, reduction gear device 303, rotation angle control gear 304, rotation angle control, which are motor driving circuits, are molded in a semi-cylindrical shape A pin 305, a rotating shaft 211, a rapid rotation on / off switch 212, a power on / off and angle control switch 213, and a power supply source 306 were integrated into the case, and are detailed in the assembly diagram of FIG. Indicated.

The motor driving circuit 301 is configured by slightly modifying a general multivibrator circuit. When the pulse motor 302 starts to rotate, the rotational force reduced at a low speed through the reduction gear set 303 is applied to the rotating shaft 211. The rotating nozzle 500 which is transmitted and shaped to be inserted and fixed to the rotating shaft 211 is rotated.

On the other hand, the multi-vibrator circuit widely known is that the frequency changes only by adding or subtracting the value of the resistor [R] or the capacitor [C] used as a time constant, so that a pulse motor (adding one switch that can change the R or C value) is added. The rotational speed of 302 can be added or decreased, and the low-speed rotation and the rapid rotation on / off switch are shown in FIG.

In addition, the multivibrator circuit is a low power consumption circuit, and the characteristic of the pulse motor implemented by this circuit is that if the motor shaft is forcibly stopped, a repulsive force is applied to automatically reverse the rotation, and there is no control on the rotation shaft 211. Without the device, it will continue to rotate 360 degrees in the first given direction. Herein, a method of varying the angle by providing a function thereof to enable adjustment of the rotation angle will be described with reference to FIG. 5.

The amount of rotation reduced at low speed through the reduction gear set 303 is controlled in conjunction with the rotation angle adjustment gear 304, the rotation angle adjustment pin 305, and the rotation angle adjustment pin 305 fixed on the rotation shaft 211. By the power on and off and the angle control switch 213, it is possible to maximize the variable range from 0 degrees to 360 degrees, the method is shown in detail in the example of the angle adjustment method of FIG.

As an application example of the present invention, Figure 5 shows an example of applying a battery as a power source of the present invention and Figure 6 shows an example used in conjunction with the power supply in the humidifier body, a rotating motor is a vibration motor of a mobile phone, such as other small motors It is natural that a person skilled in the art can apply a partially modified or altered method in the rotation method and the control method for the rotation range.

As described above, in a humidifier for indoor use, it is possible to escape from partial humidification of a limited area, which is a problem of the conventional fixed spraying method, to humidify a large area evenly within a short time and to solve the problem that is caused by continuous humidification of a specific area. It can be said that it has enhanced convenience.
