Example 1

1 and 2 are combined perspective view and exploded perspective view showing the automatic fragrance injection according to the first embodiment of the present invention, parts such as the control unit and the housing are shown in an omitted state. Fragrance automatic injection device according to the first embodiment of the present invention is a control unit (not shown) to control the operation of the scent automatic injection device as a whole by processing a signal generated by a timer or an infrared sensor, and the electric motor operated by the control unit A drive conversion unit for converting the rotational driving force of the motor 3 and the electric motor 3 into a linear motion of pressing the nozzle unit 12 mounted on the discharge pipe 11 of the fragrance storage can 1, and the control unit; , A motor (3), a drive conversion unit, and a fragrance storage can (1) are inserted and mounted in a housing (not shown).

The drive conversion unit is mounted on the electric motor 3, the mounting plate (2) is formed integrally with a plurality of shafts, the pinion gear 31 is pressed-mounted to the rotating shaft of the electric motor (3), the pinion gear Gear 31 and gear reduction reduce the number of revolutions per unit time, and gear reduction gear 32 arranged on the mounting plate (2), gear reduction and the gear reducer 32 and the cam 51 and the cam 51 around Guide grooves 52 are formed in the cam gear 5 arranged on the mounting plate 2, and the operation protrusion 43 inserted into the guide grooves 52 and moving in accordance with the shape of the cam 51. According to the movement of the actuating protrusion 43, a nozzle pressing part 44 for pressing the nozzle part 12 is formed, and one end thereof includes an actuating lever 4 arranged on the mounting plate 2. .

The actuating lever (4) is an actuating protrusion (43) and the fragrance moving along the shaft insertion portion (46) inserted into the shaft formed on the mounting plate (2) and the guide groove (52) of the cam gear (5). A nozzle pressing portion 44 for pressing the nozzle 12 mounted on the discharge pipe 11 of the storage can 1 is formed, and prevents the operation protrusion 43 from being separated from the guide groove 52. The long hole 45 is fixed to the shaft formed in the mounting plate 2 so as to be movable up and down with a screw.

The operation will be described with reference to FIG. 3a, 3b and 3c are shown only the drive conversion unit and the electric motor (3) of the automatic fragrance injection device according to the first embodiment of the present invention, the state before each operation, the fragrance storage can 1 is mounted In the state of the spray operation and the state in which the spray operation is carried out in the state that the perfume storage can (1) is not mounted.

First, the operation in the state where the fragrance storage can 1 is mounted will be described. When the electric motor 3 receives a signal from the controller (not shown) and operates for a short time of about 0.2 seconds, the pinion gear 31 press-fitted to the electric motor 3 rotates in a clockwise direction and the reduction gear ( 32 is rotated counterclockwise, and the cam gear 5 is rotated clockwise again. Then, the cam 51 of the cam gear 5, which was facing the 3 o'clock direction before rotation, also rotates clockwise, and the actuating protrusion 43 of the actuating lever 4 moves along it, as shown in FIG. 3B. The nozzle pressing portion 44 of (4) presses the nozzle 12 mounted on the discharge pipe 11 of the fragrance storage can 1 to perform the spraying operation.

As mentioned above, since the operation of the electric motor 3 is made in a short time of about 0.2 seconds, the injection operation is caused by the torque generated momentarily. The amount of torque generated is moved by operating the operating lever 4 in the state in which the fragrance storage can 1 is mounted (the discharge pipe 11 of the fragrance storage can is supported by a built-in compression spring). Pressing is enough to cause the injection operation, which can be controlled by operating the control unit. Accordingly, after the spraying operation, the operating lever 4 is lifted by the restoring force of the compression spring built into the fragrance storage can 1, and thus the cam gear 5 is rotated counterclockwise so that It becomes like FIG. 3A.

Next, the operation in the state where the fragrance storage can 1 is not mounted will be described. As in the state in which the fragrance storage can 1 is mounted, when the electric motor 3 receives a signal from the control unit and operates for a short time of about 0.2 seconds in the pre-operation state of FIG. 3A, the electric motor 3 The pushed pinion gear 31 rotates clockwise, the reduction gear 32 rotates counterclockwise, and the cam gear 5 rotates clockwise. Then, the cam 51 of the cam gear 5, which was facing the 3 o'clock direction before operation, also rotates clockwise and stops toward the 9 o'clock direction as shown in FIG. 3C, so that the pressing portion 44 of the operating lever 4 is stopped. The position is maintained at a position high enough to easily mount the fragrance storage can 1.

The reason is that the cam gear 5, as shown in detail in Figure 3d, the inclined guide path that can be carried over the operating projections 43 when rotating in the state that the fragrance storage can (1) is not installed ( 57, a temporary portion for limiting the movement of the operation projections 43 defined between the inclined guideway 57 and the wall portion 59 protruding from the inclined guideway 57 and the wall portion 59; This is because the fixing groove 58 is formed. Therefore, when the cam motor 5 rotates clockwise by operating the electric motor 3 while the fragrance storage can 1 is not installed, the actuating protrusion 43 of the actuating lever 4 is guide groove 52. ), The torque is attenuated by the two inclined guideways 57, and the movement is stopped by the temporary fixing groove 58 again.

Accordingly, regardless of whether the fragrance storage can 1 is mounted, the nozzle pressing portion 44 position (height) of the operating lever 4 which can easily insert the fragrance storage can 1 at all times after the spraying operation occurs. ) Can be maintained.

Example 2

The drive conversion unit is mounted on the electric motor 3, the mounting plate (2) is formed integrally with a plurality of shafts, the pinion gear 31 is pressed-mounted to the rotating shaft of the electric motor (3), the pinion gear Gear 31 and gear reduction reduce the number of revolutions per unit time, and gear reduction gear 32 built in the mounting plate (2), gear reducer 32 and the gear 51 and the cam 51 ' A guide groove 52 'is formed around the cam gear 5' and the guide groove 52 'which is installed in the mounting plate 2, and moves along the shape of the cam 51'. According to the movement of the actuating protrusion 43 and the actuating protrusion 43, a nozzle pressing portion 44 for pressing the nozzle part 12 is formed, and an actuating lever 4 having one side end arranged on the mounting plate 2. It is configured to include).

The actuating lever 4 includes an actuating protrusion 43 moving along the shaft inserting portion 46 inserted into the shaft formed on the mounting plate 2 and the guide groove 52 'of the cam gear 5'. A nozzle pressing portion 44 for pressing the nozzle 12 mounted on the discharge pipe 11 of the fragrance storage can 1 is formed, and the operation protrusion 43 is separated from the guide groove 52 '. A long hole 45 is formed on the shaft formed on the mounting plate 2 so as to be prevented from being fixed to the shaft.

In addition, in the present embodiment, unlike the first embodiment, a spring latch 53 is formed in the cam 51 'of the cam gear 5' at a part far from the center thereof, and the mounting plate 2 The upper portion of the spring latch 21 is formed, it can be seen that the tension spring 54 is mounted between the two spring latch (53) (21).

The operation will be described with reference to FIG. 6A and 6B show only the drive conversion unit and the electric motor 3 of the fragrance automatic injection device according to the second embodiment of the present invention. When the electric motor 3 receives a signal from the controller (not shown) and operates for a short time of about 0.2 seconds, the pinion gear 31 press-fitted to the electric motor 3 rotates in a clockwise direction and the reduction gear ( 32 is rotated counterclockwise, and the cam gear 5 'is rotated clockwise. Then, the cam 51 'of the cam gear 5' which has been turned to 3 o'clock before operation also rotates clockwise, and the actuating projection 43 of the actuating lever 4 is connected to the cam gear 5 '. The nozzle pressing part 44 moves along the formed guide groove 52 'and presses the nozzle 12 mounted on the discharge pipe 11 of the fragrance storage can 1 to perform the spraying operation.

At this time, the tension spring 54 is in an extended state to generate a pulling force. Therefore, after the spraying operation, the cam gear 5 'is rotated counterclockwise or clockwise by the restoring force of the tension spring 54 regardless of whether the fragrance storage can 1 is installed. State is maintained.

As mentioned above, since the operation of the electric motor 3 is made in a short time of about 0.2 seconds, the injection operation is caused by the torque generated momentarily. The amount of torque generated is sufficient to cause the injection operation by pressing the nozzle 12 by moving the operation lever 4 in the state in which the fragrance storage can 1 is mounted, which can be controlled by operating the control unit. However, in the present embodiment, according to the mounting of the tension spring 54, it is natural that a larger torque than the first embodiment is required.

Accordingly, since the operating lever 4 of the automatic fragrance injection device is always in a lifted state, replacement and mounting of the fragrance storage can 1 is advantageous.
