Description

[Detailed Description of the Invention] The present invention relates to a sterilization device that sterilizes hands and fingers by spraying a volatile disinfectant such as alcohol in the form of a mist.

Generally, when working in a food factory or the like, workers sterilize their hands with a disinfectant before starting work.

Conventionally, there have been methods of storing disinfectant in a container and immersing the hands in the disinfectant to sterilize the disinfectant, and devices such as hand sprays and automatic sterilizers have been available.

When using a disinfectant solution stored in a container, the disinfectant solution is wiped off with a towel, etc., which often results in cross-contamination of the sterilized hands with the towel.

In the case of hand spray, the method is to operate the spray with one hand, sterilize the other hand, then switch hands and sterilize the other hand, so there is no risk of the sterilized hand becoming contaminated. There was a drawback that

Also. Automatic sterilizers optically detect when a hand is inserted into the sterilization chamber and spray disinfectant solution for a certain period of time, but the drawback is that the device requires a dog and is expensive. .

In order to eliminate the drawbacks of the above-mentioned conventional example, the present invention has been developed by inserting your hand into the sterilization chamber and pushing the push plate provided in the sterilization chamber.
To provide a sanitary, simple, and low-cost sterilizing device which sprays disinfectant by opening the valve of a spray nozzle only during that period.

Hereinafter, embodiments will be described in detail with reference to the drawings.

FIG. 1 shows one embodiment of the present invention, in which 1 is a storage tank for a volatile disinfectant (e.g. alcohol), 2 is a storage tank for pressurized gas (e.g. carbon dioxide), 3 is a spray nozzle, 4 is a disinfectant solution supply pipe, 5 is a cup for temporarily storing the disinfectant solution, 6 is a pressurized gas supply pipe, 7 is a sterilization chamber, 8 is a push plate, 9 is a push plate 80 rotating wheel, 10 is a slide shaft , 11
is a valve stem of a needle valve provided in the spray nozzle 3.

Next, the operation of this embodiment will be explained.

Now, when you insert your hand into the sterilization chamber 1 and push the push plate 8 in the direction of arrow A, the push plate 8 will rotate the rotation axis 9.

The arm 8a on the opposite side moves in the direction of arrow B and pushes the slide shaft 10.

The slide shaft 10 pushes the valve stem 11 and opens the needle valve provided inside the spray nozzle 3.

When the needle valve opens, pressurized gas passes through the spray nozzle 3 and is ejected from the nozzle at the tip.
The disinfectant inside is drawn out by the so-called atomizing action,
A mist is sprayed from the tip nozzle portion of the spray nozzle 3.

The sprayed disinfectant is poured onto the push plate 8, which is located just below the push plate 8 and is touched by hands and fingers, so that the required amount of disinfectant is sprayed and the hands and fingers are sterilized.

Next, when you release your hand from the push plate 8, the valve stem 11 returns to its original position due to the return force of the needle valve, and the push plate 8
returns, the needle valve closes, and spraying of disinfectant stops.

Note that a stopper 12 is provided to stop the arm portion 8a at a predetermined position when the push plate 8 returns.

Further, a spring or the like may be provided between the arm portion 8a and the back wall to speed up the return operation.

In this embodiment configured as described above, if you insert both hands into the sterilization chamber T and press the push plate 8 with your hands, while you are pushing it,
The spray nozzle 3 installed at the top also sprays disinfectant, making it easy to sterilize your hands.Furthermore, the push plate 8 that your hands touch is always sterilized by the sprayed disinfectant, making it extremely hygienic. It is true.

Furthermore, since the valve opening/closing mechanism has a simple structure using a lever, the cost of the sterilizer can be reduced.

The main body of the sterilizer is surrounded by panels except for the front surface of the sterilization chamber 7 to prevent the sprayed disinfectant from scattering to the outside.

The embodiments in the drawings are shown with panels removed.

Furthermore, a tray may be provided at the bottom of the sterilization chamber to receive the disinfectant solution.

Fig. 2 shows another embodiment of the present invention, in which the same reference numerals as in Fig. 1 indicate the same parts, and 13 indicates a pressurized disinfectant solution (for example, alcohol and carbon dioxide gas). 14 is a spray nozzle, and 15 is a disinfectant solution supply pipe.

In the case of this embodiment, since the disinfectant is mixed with pressurized gas, the so-called atomizing spray nozzle as in the embodiment shown in FIG. When the valve opens, pressurized disinfectant is sprayed directly.

The opening/closing mechanism of the needle valve is exactly the same as the embodiment shown in FIG.

As explained above, according to the present invention, by simply inserting both hands into the sterilization chamber and pressing the push plate with the hands, the required amount of disinfectant is sprayed from the spray nozzle, and the hands and fingers can be easily sterilized. Furthermore, since the disinfectant is volatile, it dries immediately naturally and is extremely hygienic as there is no need to wipe it off with a towel or the like, which can cause secondary contamination. Since it is a simple configuration, it has the advantage that the manufacturing cost of the device can be significantly reduced.
