Description

[Detailed explanation of the idea] The present invention relates to an improvement of a small hand-operated sprayer.

In this type of sprayer, a pressurizer placed in the flow path between the container body and the nozzle hole of the spray head connects the lower small-diameter cylinder and the upper large-diameter cylinder, with an intermediate valve at the bottom and an intermediate valve at the top. It is formed by communicating with a slidable communication member equipped with a discharge valve, and when the spray head is pressed down against the return spring to pressurize the liquid in the small diameter cylinder, this pressurized liquid opens the intermediate valve. and transfer the pressurized liquid to the large diameter cylinder side,
The pressure difference based on the diameter difference between both cylinders causes the communication member to move downward, opening the discharge valve, and spraying from the nozzle hole.The projecting height of the spray head is kept low, making it convenient for use and storage. Systems designed for convenience are known.

In some cases, such a sprayer is required to be able to spray the content liquid not only in the form of mist but also directly in the form of a water column.

The present invention aims to provide a convenient small hand-operated sprayer that can be used for both direct and misting purposes with a simple operation by improving a portion of the spray head and large-diameter cylinder.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a mounting member, 2 and 3 are inner and outer engaging tubes erected from this mounting member 1, and 4 is a spray head that is guided by this outer engaging tube 3 and is pressed down. The member 1 is attached to the mouth and neck of a container body (not shown) by fitting or screwing, and a pressurizing chamber is provided inside through this attachment member 1.

As mentioned above, this pressurizing chamber has a small-diameter cylinder 5 at the bottom and a large-diameter cylinder 6 at the top, which are guided by the inner engaging cylinder 2 and are arranged so as to be movable up and down, and between them, there is an intermediate valve at the bottom. , communicated by a slidable communication member 8 with a discharge valve 7 arranged on the upper part, and a small diameter cylinder 5
At the bottom, a suction pipe 9 that hangs downwards inside the container is connected through a suction valve, and a large diameter cylinder 6 is connected to the lower part.
The spray head 4, which has a nozzle hole 11 that communicates with the spray head through a discharge passage 10, is urged upward by a return spring via a communication member 8.

Therefore, when the spray head 4 is pushed down against the return spring to narrow the internal volume of the small diameter cylinder 5 and pressurize the internal liquid, this pressurized liquid opens the intermediate valve and flows through the communication member 8. Move to the large diameter cylinder 6 side,
Then, since the hydraulic pressure on the large-diameter cylinder side exceeds that on the small-diameter cylinder side, the communication member 8 is moved downward by the hydraulic pressure, which opens the discharge valve 7 and the pressurized liquid in the large-diameter cylinder 6 is discharged from the nozzle. It is ejected from the hole 11.

Here, in the present invention, the discharge passage 10 which is normally formed on the side of the spray head 4 is formed by protruding a discharge passage pipe 12 on the side of the large diameter cylinder 6, and a peripheral wall is formed around the outer part of this discharge passage pipe 12. Cut out a part of the stopper 13
A positioning tube 14 is provided with a positioning cylinder 14 erected, and a spout hole 15 is formed on one side of the discharge pipe 12 to communicate with the nozzle hole 11. A spin path 16 is recessed in the shape of a groove. On the other hand, the fitting tube 17 of the spray head 4, which is rotatably mounted by fitting the fitting tube 17 vertically installed between the discharge pipe 12 and the positioning tube 14, is locked to the stopper 13 from the outer surface of the fitting tube 17. A locking piece 18 that restricts the rotation range of the spray head 4 is provided in a protruding manner to prevent the spray head 4 from rotating.
When rotated clockwise to the limit, nozzle hole 1
1 directly communicates with the spout hole 15. Therefore, if the spray head 4 is pushed down in this state, the content liquid can be spouted out in the form of a water column, and when the spray head 4 is rotated in the opposite direction to the limit, the nozzle hole 11 is connected to the spin path. It communicates with the spout hole 15 through 16, so that if the spray head 4 is pushed down in this state, the liquid inside can be sprayed out in the form of a mist just like a normal sprayer. The outer periphery of the lower end of the large-diameter cylinder 6 is shaped like a gear 19 so as to move up and down but not rotate, and the inner periphery of the inner engaging cylinder 2 is shaped like a gear as well.

According to the present invention, the mist can be directly selected by rotating the spray head 4 by a slight angle in the opposite direction, and the liquid content can be spouted in the form of a water column or mist, which is convenient.
