Abstract

PROBLEM TO BE SOLVED: To use a liquid in a container main body to the last drop by providing a pressure outflow nozzle with an outflow stop opening formed sideward and a pressure outflow nozzle packing formed on the outer periphery of the nozzle for forming a clearance on the inner periphery at the time of pressurizing in a backflow prevention cylinder. SOLUTION: When a lever 4 is pressed, a slide shaft 8 and a piston 9 are moved in a cylinder S to press a compression spring 10, and a liquid flowing into a liquid inflow chamber D through a liquid inflow pipe D1 is sucked by moving up a check valve 7. Then the pressurized liquid is passed through a through-hole 11a of a backflow prevention cylinder 11 and also passed through a communication opening C1 of a pressure outflow nozzle 12 and flowed out of an inflow stop opening C, and then flowed out of a clearance 13al onto the inner periphery of a pressure outflow nozzle packing 13a while being pressed and jetted out of a nozzle 14a. Thereby the liquid E can be used efficiently to the last drop.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid ejector used for spraying a liquid such as a detergent or a chemical.

[0002]

2. Description of the Related Art Conventionally, as a liquid ejector of this type, a container body for storing a liquid as described in Japanese Patent Application Laid-Open No. Hei 8-58822, and a liquid ejector which is detachably attached to an opening of the container body. In a pump-equipped container comprising a pump having a suction pipe opening at an inner bottom portion of the container body, a suction pipe main body made of a flexible material that does not collapse the suction pipe, and attached to a distal end of the suction pipe main body. Also disclosed is a container with a pump, characterized in that the suction pipe body is constituted by a weight that always positions the tip end of the suction pipe body in the direction of gravity.

[0003]

However, in the above-described embodiment, there is a possibility that the suction pipe main body made of a flexible material may be deformed due to long-term use and become inflexible. Also, depending on the components of the liquid to be put into the container body, the suction pipe body may be deteriorated, and the intended use may not be possible. Further, as shown in FIG. 4 and FIG. 10 of the publication, the pump 7 must be used in reverse, so that the workability is remarkably inferior and the liquid cannot be used to the end.

In view of the above-mentioned problems, the present invention provides the container body above the ejector body so that the liquid in the container body can be completely used up without using the pump or the like upside down. It is intended to provide a liquid ejector that can be used.

[0005]

As means for achieving the above object, a container body containing a liquid is detachably mounted on an upper part of an ejector body for ejecting a liquid, with an opening part being a lower part. A liquid ejector which is provided with a check valve in the outflow path of the liquid ejector, and a backflow prevention device for forming an appropriate amount of pressurized liquid and preventing backflow when not pressurized. A nozzle body consisting of a pressurized outflow nozzle with a lateral outflow stop hole in the cylinder and a pressurized outflow nozzle packing provided on the outer periphery of the pressurized outflow nozzle and forming a gap on the inner periphery when pressurized is installed inside It is composed of a nozzle formed as follows.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a container main body in which a liquid E such as water or a liquid detergent is stored.
A cap 3 having a threaded portion at the lower portion is provided so as to be detachably formed at the upper portion. Reference numeral 2 denotes an ejector main body, which is provided with a bush 5 for preventing left and right rubbing and a packing 6 for preventing liquid leakage in order to mount the container main body 1 on an upper portion. In addition, a spherical check valve 7 is provided in the upper part connected to the liquid inflow pipe D1, and a liquid addition chamber D for temporarily storing liquid is provided therein. In order to aspirate, a slide shaft 8, a piston 9 and a compression spring 10 in a cylinder S operated by a lever 4 are provided, and an appropriate amount of pressurized liquid is jetted out. A communication hole C is provided in the backflow prevention cylinder 11 having a through hole 11a formed in the center of the left end.
1, a pressurized outflow nozzle 12 having a flow stop hole C formed at the end thereof in two sides (in two directions), a stapler portion C2 protruding at the rear, and a pressurizing nozzle wrapped around a stopper C2. A nozzle 14 having a gap 13a1 formed on the inner periphery when pressure is applied, a nozzle body 13 including a pressurized outflow nozzle packing 13a for allowing liquid to flow out, and a nozzle port 14a formed at a tip thereof for discharging liquid. Is provided.

The check valve 7 moves upward only when pressurized (when the lever 4 is pushed back), and normally prevents the liquid from flowing out of the liquid admitting chamber D naturally. .

As an example of the use of the liquid ejector constructed as described above, first, a liquid E such as a liquid detergent is put into the container body 1 and the bush 5 of the ejector body 2 is inserted into the mouth of the container body 1. The cap 3 is tightened and fixed integrally. Subsequently, when the lever 4 is pushed (opened), the slide shaft 8 and the piston 9 in the cylinder S move, and the compression spring 10 is pushed (opened), and the liquid spring D enters the liquid inlet chamber D via the liquid inflow pipe D1. The check valve 7 rises and the liquid flowing into the suction port is sucked. Next, the pressurized liquid passes through the through hole 11a of the backflow prevention cylinder 11, passes through the communication hole C1 of the pressurized outflow nozzle 12, and flows out of the outflow stop hole C. It flows out while being pressed from the gap 13a1 (a space formed by expanding the periphery when pressurized).
After that, it gushes vigorously from the nozzle port 14a.

For example, in the case of washing a car, when spraying the liquid E on the ceiling, the nozzle port 14a is lowered and the lever 4 is pushed, and when spraying the lower suspension, the nozzle port 14a is raised. The liquid E can be used efficiently until the end.

When not in use (other than pressurization)
Since the inner periphery of the pressurized outflow nozzle 13a of the nozzle body 13 is in close contact with the pressurized outflow nozzle 12, the clearance 13a1
Is not formed, so that the liquid E does not leak from the nozzle body 13 and the check valve 7 also seals the opening of the liquid admitting chamber D, so that the water pressure into the nozzle 14 is reduced.

In the above embodiment, it is desirable to use water-resistant synthetic rubber as the material of the packing, and to use a synthetic resin or the like for other materials. Further, the capacity of the container body 1 and the size of the ejector body 2 may be determined as needed.

[0012]

The present invention has the following effects. 1). Suction pipe (tube) with the container body at the top
Without having to turn over the ejector body
There is an effect that the liquid can be used to the end.
