Description

  The present invention relates to a powder sprayer, and more particularly to a powder sprayer that is suitably used for spraying powdery cosmetics.

  In general, in the case of makeup using powder, the powdery cosmetic is applied using a brush or puff, but it is difficult to make the amount of the cosmetic applied uniform, and the finish of the makeup is difficult. Unevenness may occur.

  In order to deal with such problems, for example, as shown in Patent Document 1, compressed gas is fed into a sprayer body to which the cosmetic is supplied using a compressor, and the compressed gas is supplied to the sprayer body. A technique has been proposed for spraying cosmetics in a mist form, and by adjusting the adjustment lever provided on the sprayer body, the amount of cosmetics to be applied can be finely adjusted to make the makeup finish more uniform. The technology which makes it easy is proposed.

JP 2013-42930 A

  By the way, in the conventional technology described above, an atomizing mechanism is arranged in the cosmetic supply path, and compressed gas is supplied to the atomizing mechanism, and a flow rate adjusting valve such as a needle valve provided in the atomizing mechanism is used. The atomization of the cosmetic and the amount of spraying are adjusted, and the spraying is stopped.

  Such a sprayer sprays cosmetics in the form of a mist. When this technique is applied to powdery cosmetics, for example, the flow rate adjustment valve is closed to reduce the application of the cosmetics. Or, when stopped, the powder flows and stays between the valve body and the valve seat of the flow control valve, and further, the retained powder is pressed against the valve seat by the valve body, so that the powder Is consolidated and solidified, which may cause clogging of the flow rate adjusting valve, which leaves a problem that it is difficult to apply to the application of powdery cosmetics.

  The present invention has been made in view of such conventional problems, and provides a powder sprayer that can suppress clogging as much as possible when applying powdery cosmetics. And

  In order to solve the above-described problem, the powder sprayer of the present invention is filled with powder, an opening is formed at the front end, and a powder discharge port is formed at the rear end, and A sprayer main body to which the powder container is attached and a compressed gas container connected to the sprayer main body and supplying compressed gas to the inside thereof. The tip of the powder container is fitted into the sprayer main body. A fixed portion to be attached and a support portion to which a rear end portion of the powder container is fitted are provided, and the fixed portion is supplied with compressed gas supplied from the compressed gas container. A gas supply path that leads toward the opening of the container; an open / close valve that opens and closes the gas supply path; and an operating lever that opens and closes the open / close valve. Has a spray port through which the powder discharge port of the powder container communicates It is characterized in that is.

In the powder sprayer according to the present invention, the powder container is mounted on the sprayer body with the tip thereof facing downward.
In this state, the opening at the front end of the powder container is directed downward and is opposed to the downstream side of the on-off valve, and the powder discharge port at the rear end of the powder container is located above the spray port. To communicate with.

  Here, the powder in the powder container is allowed to settle in the lower part of the powder container.

  In this state, when the compressed gas container is connected to the gas supply path and the operation lever is operated to open the on-off valve, the compressed gas in the compressed gas container is transferred from the on-off valve to the tip of the powder container. The powder which is supplied into the powder container through the opening and is settled below the powder container is blown upward, and a part of the powder is positioned above the powder container. Sprayed from the body discharge port through the spray port of the sprayer body.

  And since the opening area of the said powder discharge opening and the said spraying opening is constant, the amount of spraying mentioned above is also kept constant, and the surplus powder of the powder blown up as mentioned above faces downward. Can be dropped.

In such a powder spraying operation, the on-off valve only supplies and stops the compressed gas supplied into the powder container, and the compressed gas discharged from the on-off valve is: The powder is always pushed out in a direction away from the on-off valve.
Therefore, when spraying is stopped, the powder in the powder container moves toward the downstream side of the on-off valve (that is, the compressed gas discharge side). It is prevented from entering the working part.
Even if the powder enters the operating part of the on-off valve, the powder is pushed back toward the powder container by the flow of the compressed gas described above and stays in the operating part of the on-off valve. Is prevented.

  Therefore, during the repeated operation of spraying and stopping the powder, it is possible to prevent clogging of the operating part due to the powder being retained in the operating part of the on-off valve and being compacted. The body can be sprayed smoothly.

  Then, the distal end portion of the powder container and the fixing portion can be fixed by screwing a male screw provided at the distal end portion of the powder container with a female screw provided at the fixing portion. Further, a protrusion can be formed on one of the tip portion and the fixed portion of the powder container, and a recess can be formed on the other, and the protrusion and the recess can be fitted together.

  In the present invention, in a state where the powder container is mounted on the sprayer body, the powder discharge port provided in the powder container and the spray port provided in the sprayer body are aligned, and these Must be kept in communication.

In order to facilitate such alignment, the cross-sectional shapes of the powder container, the fixing portion, and the support portion can be non-circular.
Accordingly, the positional relationship between the powder container and the sprayer body around the axis of the powder container can be regulated, and the powder discharge port and the spray port can be easily aligned.

  In addition, by providing a display indicating the position of the powder discharge port on the rear end surface of the powder container, and mounting the powder container so that the display matches the spray port, Positioning of the body discharge port and the spray port can be further facilitated.

  As described above, according to the powder sprayer of the present invention, it is possible to secure a stable spraying action by suppressing clogging of the powder supply path, and in particular, it was used for applying powdery cosmetics. In this case, the coating amount can be stabilized and fine coating can be performed.

The

  The compressed gas supplied into the powder container 2 blows up the powder P settling below the powder container 2 and forms in the powder container 2 together with a part of the powder P. The powder is discharged from the powder discharge port 2b, whereby the powder P is sprayed.

Here, since the opening area of the powder discharge port 2 b is constant, the spray amount described above is kept constant, and the remaining powder P is circulated in the powder container 2.
Therefore, the powder P is sprayed by a certain amount, and a stable coating amount is ensured.

  In such a spraying operation of the powder P, the on-off valve 5 is always positioned upstream of the powder P, and supply and stop of the compressed gas supplied into the powder container 2 are performed. Just do.

  When spraying is stopped, the powder in the powder container 2 moves toward the downstream side of the on-off valve 5 (that is, the compressed gas exhaust port E side). The operating part of the on-off valve 5, that is, the valve seat V and the valve body 17 does not enter.

  Even if the powder enters the operating portion of the on-off valve 5, the valve body 17 and the valve seat V face each other until the valve body 17 is returned to the closed position when the spraying operation is stopped. Since the compressed gas is constantly sent between the surfaces, the powder P that has entered between the valve body 17 and the valve seat V is pushed back, and the valve body 17 and the valve seat V It does not stay in between.

Therefore, the clogging of the operating part due to the powder remaining in the operating part of the on-off valve 5 and being compacted during the repeated operation of spraying and stopping the powder can be prevented.
As a result, the above-described powder spraying can be performed smoothly and stably.
