Description

[Detailed description of the invention] The present invention is an aroma dispersion adjusting device, in particular, a box-shaped main body with an open top end that houses an aroma dispersion source inside, and an aroma dispersion window that can be rotated to adjust the opening degree of the aroma dispersion window. This invention relates to an aroma dispersion adjusting device fitted with a cap-type lid for adjustment.

Conventionally, this type of aroma diffusion adjustment device is
It is generally widely used, and the amount of fragrance released can be easily adjusted by adjusting the opening of the fragrance window by rotating the lid.

However, in conventionally known devices, the opening of the fragrance diffusion window in the lid expands and contracts in a congruent manner when the lid is rotated, so the opening of the aroma diffusion window is adjusted in a linear function by rotating the lid. Therefore, the adjustment efficiency of aroma dispersion by rotation of the lid per unit angle is not necessarily good.

Therefore, in the above-mentioned type of aroma dispersion adjusting device, the present invention improves the efficiency of adjusting the aroma dispersion by rotating the lid per unit angle compared to the conventional one, and the opening of the aroma dispersion window of the lid is made larger even when the lid is rotated by a small angle. The idea is to make it expand and contract.

That is, to explain the drawings, the aroma dispersion adjusting device of the present invention includes a box-shaped main body 1 with an open top, which houses an aroma dispersion source, for example, a container a containing a liquid aromatic agent, and a rotatable aroma dispersion lid 2 attached thereto. This is an aroma dispersion adjusting device in which a cap-type lid 3 is fitted to adjust the opening degree of the aroma dispersion window 2, and the lid 3 is rotatable up and down with its rear end as a rotation center point 0. , the aroma diffusion window 2 is formed on the side and front surface of the body wall 4 of the lid 3, or at least on the side, the aroma diffusion window on the side has a slit shape extending in the front and back direction, and when the lid 3 is rotated up and down, It is characterized in that the rotation center point 0 of the lid 3 is located at a position offset from the point where the extension line of the upper edge of the main body 1 and the long side of the slit-shaped aroma dispersion window 2' intersect. In the embodiment of the invention, the main body 1 is shaped like a so-called shamisen body, and the lid 3 is fitted inside the upper end opening 1a of the main body 1. In the figure, reference numeral 5 indicates a window formed at the bottom of the main body 1 for viewing the remaining amount of liquid fragrance in the container a. Reference numeral 6 denotes a removable bottom plate of the main body 1, which can be removed to accommodate an aroma emitting source inside the main body 1. 7 is a reinforcing bar of the lid 3.

According to the present invention, when the lid 3 is rotated up and down, the point where the extension line of the slit-shaped aroma dispersion window 2' extending in the front-rear direction on the side surface of the body wall 4 of the lid 3 and the upper edge of the main body 1 intersects. , since the rotational center point 0 of the lid 3 is shifted, when the lid 3 is rotated up and down about the center point 0, the portion of the slit-shaped aroma diffusion window 2' that is outside the inner space of the main body 1, i.e. The opening of the slit-shaped aroma diffusion window 2' is expanded and contracted in a quadratic curve, and therefore, compared to the conventional device in which the aroma diffusion window is expanded and contracted in a linear function, the opening of the slit-shaped aroma diffusion window 2' is expanded and contracted in a quadratic manner. The adjustment efficiency of aroma dispersion by the rotation of the lid 3 is high, and the opening of the aroma dispersion window 2' of the lid 3 can be greatly expanded or reduced even by rotation at a small angle.

Claims (1)

[Scope of utility model registration request] The aroma dispersion adjusting device has a box-shaped main body with an open top end that accommodates an aroma dispersion source inside, and a cap-shaped lid fitted with an aroma dispersion window and which adjusts the opening degree of the aroma dispersion window by rotation. The lid is rotatable up and down with the rear end as a center of rotation, and an aroma-dispersing window is formed on the side and front surface of the body wall of the lid, or at least on the side, and the aroma-dispersing window on the side surface rotates in the front-rear direction. When the lid is rotated up and down, the center of rotation of the lid is shifted from the point where the extension line of the upper edge of the main body intersects with the long side of the slit-shaped aroma dispersion window. Fragrance dispersion adjustment device.
