Embodiment Construction

[0033] Figures 2-4 are schematic diagrams, not to scale, and some dimensions are exaggerated for clarity.

[0034] in figure 1 , The storage tank 1 (bottle or can) has a neck 2, a rod-shaped porous wick 3 is assembled in the neck 2, and the rod-shaped porous wick is surrounded by a tightly fitting elastic plug 4 that surrounds the wick. Fits tightly in the neck. The wick has a circular cross-section, and the part of the wick that protrudes from the storage tank is slightly conical, as shown in Figure 2, with a narrow end 5 away from the storage tank and a wider end 6 close to the storage tank. . This makes it easy to mount the diffusion surface 7 on the wick. The diffusion surface 7 has holes 8 whose diameter is larger than the diameter of the end 5 but smaller than the diameter of the end 6. The hole 8 is formed so that it fits with the truncated cone surface section of the wick, thereby ensuring good contact and liquid transfer. The diffusion surface is a curved plate of non-poro...

Abstract

A device adapted to provide volatile liquid material to an atmosphere comprising a reservoir (1) containing volatile liquid material, a rod-like transfer member (3, 4) extending therefrom and adapted to transfer liquid from the reservoir, and at least one diffusion surface adapted to receive the liquid from the transfer member and facilitate its evaporation into the atmosphere, the diffusion surface extending essentially laterally from the transfer member and comprising at least one non-integral, non-porous sheet bearing a surface capillarity, which sheet has an extent and a capillarity sufficient to allow an appropriate evaporation. The device is cheap and easy to construct, versatile and diffuses odour without major changes of the odour over time.

Description

Technical field [0001] The invention relates to a device for diffusing volatile materials into the atmosphere. Background technique [0002] Devices for diffusing volatile materials (such as fragrances, air fresheners, anti-mold and anti-fungal materials, and insect repellents) into the atmosphere are well known in the art. A typical device includes: a container for storing liquid volatile materials; and a diffusion member that supplies the material to the atmosphere by evaporating the surface. The diffusion member receives the liquid for evaporation through a liquid conveying member (usually a fibrous wick). Despite the advantages of being cheap and simple, ordinary wicks have the disadvantage of certain materials (such as fragrances) that due to the fractional distillation of components, the material diffused from the device will change after a certain period of time because of higher volatility. The sexual components diffuse earlier (and run out earlier), which is similar to w...
