JPS604620Y2 - Injection pipe for sprayer - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a spray pipe for a sprayer suitable for spraying insecticidal liquid, disinfectant liquid, etc. into a narrow space.

In an aerosol sprayer that uses compressed gas sealed in the container to spray out the chemical liquid in the container, an injection pipe of the required length is connected to the injection port that also serves as a push button at the top of the container, with the tip facing downward or forward. A type of spraying system has been developed in which this pipe is inserted into a narrow space, but for operational purposes, this injection pipe needs to be a rigid tube that protrudes in a certain direction, so it cannot be used in a specific direction with respect to the sprayer container. It is fixed, and each time for the required injection direction,
It takes effort to replace it with a separate injection pipe.

For this reason, some designs have been devised in which the mounting part can be rotated.
Moreover, this valve part acts as a resistance, causing inconveniences such as leakage and uneven spraying.

This device has a simple structure and can be rotated and fixed reliably, and as shown in FIGS. 1 is provided protrudingly, and a 45mm
°The front surface of a stepped block-shaped joint member A made of a material with appropriate elasticity, such as rubber or synthetic resin, has bent holes 2 that communicate with each other at an angle, and is made of a hard or semi-hard synthetic resin. A straight pipe is bent at 45 degrees to one side near its base end to form a bent part 4 connected to the straight part 3.The bent part 4 of the tip pipe B is press-fitted against elasticity. It is.

This device has the above-mentioned structure, and is used by attaching the short tube 1 to the nozzle of the sprayer. In the state shown in FIG. When the tip tube B is turned 180 degrees against its elasticity as shown in FIG. 3, the straight portion 3 of the tip tube B is displaced approximately horizontally.

In addition, for normal spraying that does not require the tip tube B, the joint member A can be removed from the sprayer's push button injection port a', or the push button injection port itself can be connected to the sprayer's push button injection port a'.
It is used by removing it from the stem of ' and replacing it with another push button and injection port.

As described above, this device has a simple structure, and the tip tube B and the joint member A are fixed by a considerable amount of pressure friction between the outer circumferential surface of the bent portion 4 and the inner circumferential surface of the bending hole 2. Therefore, there is no fear that the spray tip tube B will rotate inadvertently, and even spraying can be continued at all times.

In addition, since the tip tube B is bent at 45 degrees at its base end, when rotated 180', the tip tube is positioned horizontally in the extension direction of the short tube 1, so the injection force is not reduced. It's done smoothly.

[Brief explanation of drawings]

FIG. 1 is a side sectional view, FIG. 2 is an exploded perspective view of each part, and FIG. 3 is a side sectional view with the tip tube facing forward. In the figure, A indicates a joint member, B indicates a tip tube, 1 indicates a short tube, 2 indicates a bent hole, 3 indicates a straight portion, and 4 indicates a bent portion.

Claims (1)

[Scope of utility model registration request] The above-mentioned joint member A has a stepped block shape, which has a short tube 1 that fits the injection port of a desired sprayer projected on the back side, and a bending hole 2 that communicates with the short tube 1 at a 45° inclination on the front side. In the bending hole 2, a straight tube of the required length is bent at an appropriate position near the proximal end by 45 degrees to one side to form a bent portion 4 connected to the straight portion 3.The bent portion 4 of the distal tube B is rotated. A sprayer injection pipe that can be press-fitted.
