DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of an automatic spraying mechanism and a garbage disposal apparatus according to the present invention will be described in detail with reference to the drawings. (1) Automatic Spraying Mechanism FIG. 1 is a partially fragmented front view showing a configuration example of an automatic spraying mechanism 100 as an embodiment of the present invention. In this embodiment, a spraying device that operates by opening the lid is provided,
The rotating force of the lid at the time of opening the lid can be applied to the button pressing force of the spraying means, and the spray target can be sprayed without having to provide a drive device such as a solenoid or a motor.

The automatic spraying mechanism 100 according to the present invention is a mechanism for automatically spraying an agent to be sprayed on a desired container. The automatic spraying mechanism 100 has the lid 2, and an arbitrary container 30
It is made to cover the top. The container 30 is a garbage box (garbage pail), a decomposition tank of a garbage disposal device, or the like. The lid 2 has left and right shaft portions 2A and 2B. The shaft portions 2A and 2B are provided with opening portions (bearing portions) 2 provided on the left and right sides of the cabinet 1 for storing the container 30 and the like.
C, 2D (one not shown) is rotatably engaged.

A spraying means 31 is attached to the outside of the container 30, for example, on the side of the cabinet 1, so that the spraying agent 40 is sprayed by the rotational force generated by the "opening" operation of the lid 2. Of course, the spraying means 31 may be provided in the cabinet 1. In this example, the shaft 2A of the lid 2
The cam part 41 is attached to one end. The spraying means 31 is a gas-filled cylinder containing a propellant to be sprayed or a manual pump type spray containing a propellant. As the spray target 40, a deodorant, a fragrance, an insecticide, or a microorganism propagation agent is used. Of course, different spraying means 31 of the agent to be sprayed 40 may be used in combination within a range that does not affect the human body.

In this example, a button 32 for spraying operation is provided above the spraying means 31, and this button 32 is
The spraying means 31 is disposed on the side of the cabinet 1 so as to face the cabinet 1. For example, the holder 60 is attached to this position, and the spraying means 31 is detachably set on the holder 60 with the button 32 facing upward. Holder 60
Has a main body 61. The main body 61 is engaged with the side surface of the cabinet 1 by screws or the like. A support portion 62 is formed below the main body portion 61, and supports the entire spraying means 31.

The support portion 62 may be provided with a height adjustment mechanism (not shown). When the length of the spraying means 31 varies depending on the manufacturer, the height adjustment mechanism can be used to optimally adjust the mounting position of the spraying means 31 so that the button 32
The cam portion 41 can be brought into optimal contact with the cam portion. An Ω-shaped restricting portion 63 is formed slightly above the center of the main body, and the lateral shake is restricted by holding the spraying means 31 at the Ω-shaped portion. The button 32 is formed with a nozzle 32A, and when the button 32 is pressed, the spray target is ejected from the nozzle 32A to the outside by the injection gas inside the cylinder.

Next, the operation of the automatic spraying mechanism 100 will be described. FIG. 2 is a configuration example of the automatic spraying mechanism 100 (when the lid is closed).
FIG. 3 is a side view of the container 30 showing an operation example (when the lid is opened), and FIG. 4 is a side view of the container 30 showing the operation example (when the nozzle is pressed). FIG. In this example, when the lid 2 exceeds a preset rotation angle θx (x = 1) by the “opening” operation of the lid 2, the cam 41 presses the button 32 of the spraying means 31. It is assumed. The cover 2 shown in FIG. 2 is formed so that the vicinity of the shaft 2A of the cover 2 is obliquely bent so as to fit the cabinet 1 in which the opening 1A is inclined. FIG. 2 shows a state in which the lid 2 is closed with respect to the oblique opening 1A.

The cam portion 41 has an elliptical shape having a predetermined thickness, and the shaft portion 2A of the lid 2 shown in FIG.
It is attached to the position shifted to the lower right side from the center of. At the same time, the oval-shaped portion of the cam portion 41 is attached so as to be obliquely upward to the left. This position is the home position of the cam portion 41 when the lid is closed. At this position, there is a gap δ between the cam portion 41 and the button 32 of the spraying means 31.
Therefore, the button 32 is not pressed and the spray target 40 is not ejected.

Next, when the cover 2 in the closed state shown in FIG. 2 is opened to the position shown in FIG. 3, the cam portion 41 comes into contact with the button 32. In this example, it is a position where the lid 2 is rotated by θ1 = 90 ° from the home position including the inclination of the lid 2. This position is a state where the gap between the cam portion 41 and the button 32 is δ = 0, and is exactly the position where the button 32 is not to be pressed (hereinafter, referred to as a pressing start position). Therefore, at this stage, the spray target material 40 has not been jetted yet.

Further, when the cover 2 is opened from the pressing start position shown in FIG. 3 to the position shown in FIG. 4, the opening step (θ1 <
The cam portion 41 presses the button 32 at θx ≦ θ2 + δθ). In this example, it is a position where the lid 2 is rotated by θ2 = 135 ° from the home position including the inclination of the lid 2. This position is a state where the gap between the cam portion 41 and the button 32 is −δ ′ (the position where the button 32 is pressed most strongly). Accordingly, the button 32 is pressed at this position, and the sprayed agent 40 is jetted vigorously. Here, δθ is a delay angle until the cam portion 41 does not completely contact the button 32 when the lid 2 is rotated beyond θ2 = 135 °.

As described above, according to the automatic spraying mechanism 100 according to the present embodiment, when the cover 2 covering the desired container 30 is opened, the spraying means 31 is rotated by the opening force of the cover 2. Operates to spray the agent to be sprayed 40. Therefore, the power for opening the lid 2 at the time of opening the lid can be applied to the button pressing force of the spraying means 31, so that the spraying means 31 removes the power from the container 30 without providing a driving device such as a solenoid or a motor. Spraying agent 40 such as deodorant and fragrance
Can be sprayed. Thereby, the automatic spraying mechanism 100 can be sufficiently applied to a garbage box and a garbage disposal device. In addition, production costs and power consumption can be reduced by eliminating the need for these driving devices.
