Description

  The present invention relates to a liquid supply device for continuously releasing a fragrance or the like from the surface of a pavement, and more specifically, supplying a volatile liquid such as a scent or the like continuously or temporarily inside a water-retaining pavement, The present invention relates to a liquid supply apparatus for continuously releasing a scent suitable for an environment where a water-retaining pavement is provided from the surface of the water-retaining pavement.

  In recent years, the global warming phenomenon, the heat island phenomenon in urban areas, and the thermal environment in the summer around the main road have become very problematic. The heat island phenomenon occurs because high-rise buildings in the urbanized area block the air flow, and heat is absorbed on the paved road surface by direct sunlight.

In order to suppress the heat island phenomenon, a filler having a water retention property is injected into a void portion of a pavement body such as a water-permeable asphalt pavement having a continuous void, a water-permeable concrete pavement, and a water-permeable resin pavement, and moisture is added to the filler. It is considered that the water-retaining pavement in which the water is retained is the most effective. This water-retaining pavement has the effect of reducing the radiant heat from the pavement by lowering the pavement temperature and the surrounding temperature by using the heat of vaporization caused by the evaporation of water retained in the pavement.
However, no technology has been reported to date to emit scent by utilizing the heat of vaporization caused by evaporation of the retained water.
On the other hand, as for the pavement that diverges the scent, a rubber chip flat pavement block (see Patent Document 1) and a wooden pavement have been reported (see Patent Document 2).
The pavement that emits these fragrances kneads the fragrance into materials such as rubber chips and wood, so the fragrance does not come out if the fragrance in the pavement runs out, and you can enjoy the fragrance only for a short time I could not do it. Moreover, the mechanism for supplying moisture in the water-retaining pavement is usually a fairly large device (see, for example, Patent Documents 3 and 4), and a fragrance can be mixed in the device for supplying moisture. Since a large amount of fragrance is required, there is a problem in cost.
