Abstract

PURPOSE:To make it possible to inject a liquid in a liquid form according to necessity, by allowing a liquid passage to communicate with a nozzle orifice when a stem pipe erected from the pump part mounted to a container body and the spray head inlaid with the upper end thereof are relatively rotated at a certain position. CONSTITUTION:The liquid in the container body 1 is sucked into a pump chamber by the up-and-down movement of a spray head 5 inlaid with the upper end of the stem pipe 4 erected from the pump part of the container body 1 in a water-right state and sprayed from a nozzle orifice 6a through the pipe orifice 4a of a pipe 4. Herein, the pipe 4 and the head 5 are made relatively rotatable and, when the head 5 is set to a certain position, a first liquid passage 13, which is provided to the outer surface of the pipe 4 by drilling and has no spin mechanism, is communicated with the pipe orifice 4a and the inner end of the orifice 6. Therefore, the liquid can be injected without being atomized. At the other relative position of the pipe 4 and the head 5, only a second liquid passage 12 with a spin mechanism provided between the outer surface of the pipe 4 and the inner surface of the head 5 by drilling is communicated with the orifice 6 and the liquid is sprayed.

Description

[Detailed Description of the Invention] A stem pipe is raised from the pump section, and the liquid inside the container is sucked into the pump chamber by vertical movement of the spray head that is watertightly fitted to the upper end of the stem pipe. This invention relates to a small-sized atomizer that is provided so that it can be sprayed through a nozzle hole opened on the side surface of the mist head through the inside of a stem tube.

This type of sprayer is widely used for spraying cosmetic liquids, etc., but since it only has the function of a sprayer, it can be used, for example, by receiving a small amount of liquid in the depression of the palm. This was inconvenient when you wanted to use it.

The present invention eliminates such inconvenience, and is designed so that it can be used not only as an atomizer but also to eject it as a liquid without atomizing it if necessary.

First, the general structure of this type of sprayer will be explained. (1) is a container body, and inside the container body, a cylinder 2 is attached, and an outward flange 3 attached to the upper end is connected to the top surface of the mouth of the container body. They are placed vertically together. A pump part is formed in the cylinder, and a stem pipe 4 is made to stand up from the pump part. By moving up and down a spray head 5 positioned at the upper end of the stem pipe, the liquid in the container body is pumped. The liquid inside the pump section is sucked into the stem tube hole 4a of the stem tube.
The spray head is configured to be sprayed through a nozzle hole 6 opened on the side surface of the spray head. 7 is the outfit? Simply pass the stem tube through the flange hole 9 of the inward flange 8 provided on the inner surface of the intermediate part, screw the lower λ1 section 10 of the mounting tube to the container body opening 1a, and then The outward flange 3 of the cylinder is sandwiched between the flange 8 and the top surface of the container. Further, the lower part of the peripheral wall 5a of the spray head is fitted into the upper part of the upper cylinder part 11 of the mounting cylinder. The stem tube is urged upward by a spring installed inside the cylinder.
After the spray head is pushed down against the bias, when the push is released, the spray head returns to its original position.

In the conventional atomizer of this kind as described above, the present invention allows the stem tube and the spray head to rotate relative to each other, and the rotation causes an H-level relative to the stem tube. If the spray head is moved up and down when the atomization head is set at the position where the atomization head is formed, the liquid will be ejected from the nozzle hole without being atomized. It was designed to spray when moved up and down.

As a structure for this purpose, as shown in FIGS. 2 and 3, a second liquid passage 12 with a spin mechanism was formed in the inner wall of the spray head in which the nozzle hole 6 was formed. The passage is not limited to the one shown in the illustration, but any passage may be used as long as it rotates at high speed when the liquid that has passed through the passage enters the nozzle hole. Further, a first liquid passage 13 without a spin mechanism was bored on the outer surface of the fitting part of the stem pipe to the spray head. The passage may be perpendicularly bored from the upper end of the stem tube to 1r1 to the extent that it can communicate with all the nozzle holes 6.

As shown in FIGS. 1 and 2, the first liquid passage 13 without a spin mechanism is placed in a position where it does not communicate with the nozzle hole 6,
Moving the mist head up and down in front of the altar will cause spraying, so rotate the KIW head relative to the stem pipe, connect the first + & integral passage J3 that does not use the spin mechanism to the nozzle hole, and move the spray head to the bottom. When you tilt it, the liquid will gush out without being exposed.

In the case of the illustrated example, if the first liquid passage is communicated with the nozzle hole, both the first and second liquid passages will be in communication with the nozzle hole, but due to the difference in resistance caused by the passage of the liquid, most of the Since the ejected liquid passes through the first liquid passage, the ejected liquid will not be atomized. However, the second liquid passage may be formed on the outer surface of the stem tube with a distance of 11.4 from the first liquid passage.
In this case, only one of the passages will communicate with the nozzle hole.

Various methods can be considered for rotating the spray head 5 with respect to the stem tube 4. The simplest method is
- Hold the stem tube with your power hand and l! with your other hand! Just turn the J fog head to the specified position. In this case, since the upper half of the mounting cylinder becomes an obstacle, a mounting cylinder with no upper half of the cylinder is used.

In the illustrated example, a vertical rIlj 14 is bored in the stem tube, a horizontal hole 15 is bored in the mounting tube, and a clamping lever 16 is inserted into the horizontal hole as shown in FIG. A vertical protrusion 17 is fitted into the vertical aq, and a vertical groove 18 is provided on the inner surface of the upper half of the mounting cylinder, and a vertical protrusion I9 is provided on the outer surface of the peripheral wall of the spray head. When the holding lever 16 is turned in front of the altar, the stem tube is turned and the first liquid passage 13 is brought into communication with the nozzle hole. Furthermore, as a third method, it is conceivable to prevent rotation of the stem tube by an appropriate method, and then rotate the stem tube by using a lever 20 attached to the spray head or by holding the spray head directly in the hand.

The sprayer to which the present invention can be applied is not limited to the one illustrated, but can be applied to various other types.

Since the present invention has the above-mentioned configuration, by simply rotating the spray head relative to the stem pipe or the stem pipe relative to the spray head, it can be used as a sprayer or as an ejector that directly sprays liquid. It is extremely convenient to use and its operation is simple.

Claims (1)

[Scope of Claims] (11) A stem pipe 4 is erected from the pump section attached to the container body, and the liquid inside the container is pumped into the pump chamber by vertical movement of the spray head 5, which is watertightly fitted to the upper end of the stem pipe.
