Abstract

This specification discloses a deodorant device installed on a shoe. The deodorant device includes a pouch having a gas outlet and at least one duct connecting from the gas outlet to the toe position inside the shoe. The pouch has the ability to elastically restore its size from contraction. As the user walks, his/her foot imposes a pressure on the pouch. The perfume or deodorant prestored inside the pouch is then ejected to prevent mold growth on the toes. It can immediately remove or decompose the bad odor inside the shoe.

Description

BACKGROUND OF THE INVENTION

1. Field of Invention
The invention relates to a deodorant device and, in particular to a deodorant device installed inside shoes to release perfume or deodorant prestored inside a pouch as the user walks.
2. Related Art
It is an embarrassing experience for some people to take off shoes in front of others because of stinky smell, which may even be difficult for themselves. Such stinky smell has no difference in genders. It may be the result of high temperatures, moisture, sweat, and mold infection. If the shoes do not have good air convection, increasing moisture can easily result in mold growth. These bacteria can decompose keratose protein and the urea and lactic acid in sweat, producing various kinds of stinky chemicals. It is the odor of these chemicals mixed inside a closed space that causes the unpleasant stink.
It is very easy to stink if shoes are worn for an entire day. If the same shoes are worn continuously for several days, they are unlikely to dry and the bacteria can grow a lot. This makes the stinky odor more serious. To avoid this, it is better to leave the shoes at a place with good air convection or to dry them with a dryer. There are deodorants sold on the market to help the consumers quickly decompose the bad odor in shoes. It also helps to drop some geranium oil or put some cotton balls dipped with lemon oil inside the shoes. The user's feet, on the other hand, can be immersed into warm water with tea oil. This does not only remove the stinky smell, but also kills the bacteria.

SUMMARY OF THE INVENTION

An objective of the invention is to provide a touch-control deodorant device for shoes that is installed inside a shoe and ejects perfume or deodorant prestored inside a pouch under pressure as the user walks.
To achieve the above objective, the disclosed deodorant device includes a pouch with a gas outlet and a duct extending from the gas outlet of the pouch to the toe position inside the shoe. The pouch has the ability to elastically restore its size from contraction. As the user walks, his/her foot imposes a pressure on the pouch. The perfume or deodorant prestored inside the pouch is then ejected to prevent mold growth on the toes. It can immediately remove or decompose the bad odor inside the shoe.
More explicitly, the disclosed touch-control shoe deodorant device can achieve the following effects:
1. As the user walks, the perfume or deodorant prestored inside the pouch is ejected toward the toes to prevent mold from growing there. It further actively prevents the formation of stinky smell, providing a more comfortable environment for the foot.
2. The perfume or deodorant is released with the foot activities, making it convenient to use.
3. Since the perfume or deodorant is released with the foot activities, the stinky smell inside the shoe can be immediately removed or decomposed.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.
Please refer simultaneously to FIGS. 1, 2, and 3 for the first embodiment of the invention. The deodorant device 10 in the drawings includes a pouch 11 and at least one duct 12.
The pouch 11 has at least gas outlet 111 and has the ability to restore after contraction. As the user's foot moves, the pressure imposed on the pouch can eject the perfume or deodorant out. The duct 12 extends from the gas outlet 111 of the pouch 11 for guiding the perfume or deodorant sent out from the pouch 11 to a predetermined position. Preferably, the predetermined position is the toe position inside the shoe 20.
In practice, the deodorant 10 should be installed such that the pouch 11 is disposed in a region that is not directly under pressure. For example, the deodorant device 10 is installed at an appropriate position on the shoe tongue of the shoe 20 in FIG. 3. In FIGS. 4 and 5, respectively, the deodorant device 10 is installed at an appropriate position on the bottom 22 of the shoe 20. In FIGS. 6 and 7, the deodorant device 10 is installed at an appropriate position above or under the surface of the shoe pad 23.
As the user walks, the pouch 11 of the deodorant device 10 sends the perfume or deodorant to the user's toes under pressure. That is, the perfume or deodorant is sprayed to user's toes even with the shoes on. This effectively prevents mold from growing at the toes. It further actively prevents the formation of stinky smell, providing a comfortable environment for the foot.
The perfume or deodorant is prestored inside the pouch 11. As the pouch contracts/expands, air brings out the perfume or deodorant molecules for removing stinky smell. In the embodiment shown in FIG. 5, more ducts 12 are used to enlarge the range of the perfume or deodorant. In practice, the pouch 11 and the duct 12 can be integrally formed by plastic mold machining. In the embodiment of FIG. 3, an elastic absorbent 13 made of sponge is inserted inside the pouch 11. In addition to provide an extra restoring force for the pouch 11, it can hold more perfume or deodorant. As shown in FIG. 1, the duct 12 can have a pressure film region 121 on its both sides. Alternatively, the pressure film regions by the duct are removed in FIG. 8.
It should be mentioned that the perfume or deodorant can be refilled as shown in FIG. 2. At least one refill hole 112 is formed around the pouch 11. An external position corresponding to the refill hole 112 is provided with films 113 that are adhered together. The user can open the films 113 to directly refill the perfume of deodorant into the pouch 11. The refill hole 112 is sealed by sticking the films 113 together again.
Using the above-mentioned structure and design, perfume or deodorant can be efficiently sprayed at the toes of the user even when he/she has the shoes on. This can prevent molding from growing and actively forbids the formation of stinky smell, providing a comfortable environment for the foot. In particular, the perfume or deodorant is stored in the pouch to be released with the foot activities. This is very convenient in use.
Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
