を小型化できるようにしたものである。 The applicant first provided a pressurized chamber in the pump, and only when the pressure inside the pressurized chamber was increased to a certain constant pressure, the discharge valve opened and sprayed. Although we have developed an atomizer that is equipped to close the atomizing chamber and therefore atomize only at a certain atomizing pressure, the present invention further improves the compression ratio of the pressurizing chamber and increases the compression ratio of the pressurized chamber without impairing its function. This makes it possible to downsize the device.

The large-diameter cylinder is fitted into a spray head 34 having a nozzle hole 33, and as shown in the figure, a fitting cylindrical portion 36 having a cylindrical hole 35 as a connecting hole is inserted from the upper periphery of the discharge valve hole in the top wall. protrudes upward and connects it to the fitting hole 37 drilled in the spray head.
The upper end of the fitting hole is further connected to the nozzle hole. The large-diameter cylinder can move up and down using the engaging cylinder portion 8 of the previously described holding cylinder member 4 as a guide. In order to prevent the large-diameter cylinder from being pulled out, an engaging protrusion 38 is attached to the outer periphery of the lower end of the large diameter cylinder so that it can be engaged with the downward engaging surface 7. Moreover, the medium diameter cylinder 25 is fitted into the large diameter cylinder watertightly and movably up and down. A discharge valve 28 is formed by the discharge valve body 27 of the medium diameter cylinder and the discharge valve hole 32 of the large diameter cylinder.

Reference numeral 41 denotes a packing valve installed between the top of the container body mouth and the outward flange of the small-diameter cylinder-attached member. It is provided so that outside air flows into the container body through the through hole 14 and between the valve part 42 of the packing valve 41 and the lower cylindrical part of the member with a small diameter cylinder that is in pressure contact with the valve part. It is something that

に備えるものである。 When using the above configuration for the first time, first move the spray head 34 up and down several times to draw liquid into the pump consisting of a small diameter cylinder, a medium diameter cylinder, and a large diameter cylinder, and then push down the spray head. Since both the suction valve 20 and the discharge valve 28 are closed, the pressure inside the pump chamber becomes high. Then, due to the diameter difference between the small-diameter cylinder and the large-diameter cylinder, the medium-diameter cylinder is pushed down against the bias of the spring 40, and the discharge valve opens and sprays. While the spray head is descending, the high pressure inside the pump chamber is maintained, so spraying continues, but when the spray head reaches the lower limit and stops, the high pressure is eliminated and the spring is energized. The discharge valve 28 is then closed. Next, when the spray head is released, the spray head rises while keeping the discharge valve closed, and the volume inside the pump chamber expands, creating a negative pressure.Then, the suction valve 20 opens and the suction pipe 16, the liquid inside the container is sucked in to prepare for the next time when the spray head is pressed down.

ダが邪魔となることがなく好都合である。 The present invention has the above-mentioned configuration, and its pump mechanism is composed of a small diameter cylinder, a middle diameter cylinder, and a large diameter cylinder, and the middle diameter cylinder is fitted into the large diameter cylinder, and the small diameter cylinder is connected to the middle diameter cylinder. Because it is designed to be pushed inward, it is possible to increase the compression ratio of the pump chamber, that is, the pressurizing chamber, and to make the pump part smaller and more compact than before. Since it does not need to be vertically installed inside the container body as in the case of FIG. Furthermore, since the pump chamber can be provided outside the container, the small diameter cylinder does not get in the way when replenishing the container with liquid, which is convenient.
