Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a spray device.

[Background of the invention]

For example, as a means to supply mold remover to the back gap of the bathtub or to a place that cannot be reached by the user, the method shown in Fig. 4(a)
, (b) have been provided. In Fig. 4, ■ is a tank filled with mold remover, 2 is a spray gun type nozzle mechanism, 3 is a tip outlet, and 4 is a plastic connecting the tip outlet 3 and tank 1. A flexible tube 5 made by the manufacturer is a telescopic pipe attached to the distal end outlet 3 and is extendable and retractable, and the flexible tube 4 is inserted into the telescopic pipe 5. When in use, as shown in FIG. 4(a), extend the telescopic pipe 5 to a predetermined length, place the tip discharge port 3 at a predetermined position, and operate the nozzle mechanism 2 to remove mold from the tank 1. The agent is sprayed from the tip outlet 3. Therefore, it has the great advantage of being able to be easily processed even in places that are normally out of reach. In addition, even if you are working in a position that is within reach, by extending the telescopic pipe 5, you can stand at a position that far away from the mold remover being sprayed, so that the mold remover will not stick to your hands and feet. It also has the advantage of increasing safety. Another feature is that it is easy to supply the mold remover to the targeted location. However, even with the above-mentioned spray device which has such great advantages, the following problems remain. In other words, although there are few major problems with the above spray device when it is used, when it is not in use, that is, as shown in Fig. 4 (b).
A problem arises when trying to store the telescopic pipe 5 in a compressed state. In other words, since the telescoping pipe 5 can be compressed and stored, there are few storage space problems, but when the telescoping pipe 5 is retracted, the flexible tube 4 will stick out from the telescoping pipe 5, and for this reason, the flexible tube 4 may be bundled. It is necessary and takes time. Note that if the protruding flexible tube 4 is not bundled, the flexible tube 4 will often get caught on something, and there is an extremely high risk that the flexible tube 4 will be damaged. Moreover, not only is it time-consuming to bundle the flexible tubes 4, but even when the flexible tubes 4 are bundled, most of the flexible tubes 4 stick out from the telescopic pipe 5, so there is no protection for the flexible tubes 4, and the flexible tubes The risk of damage to 4 itself is high. Furthermore, when the telescopic pipe 5 is extended or contracted, the flexible tube 4 may be rubbed by the inner wall of the telescopic pipe 5, or may be pinched at the joint of the telescopic pipe 5, or due to the extension action of the telescopic pipe 5. Since the bundled flexible tubes 4 may follow suit and become unable to operate, there is an even higher risk of damage to the flexible duplexes 4. Incidentally, if the flexible tube 4 is damaged by a hole or the like, it becomes unusable. Furthermore, even when in use, the telescopic pipe 5 has only one direction, so it has the drawback that it is extremely difficult to supply mold remover to, for example, a curved inner corner.

A first object of the present invention is to provide a spray device that can supply a drug to a targeted location, such as a difficult-to-reach location, when spraying a drug, for example. A second object of the present invention is to provide a spray device that is highly safe because the user can stand at a distance from the sprayed medicine, which means that the sprayed medicine is less likely to get on the hands or feet. A third object of the present invention is to provide a spray device that requires less storage space when not in use, that is, when stored, while the first and second objects mentioned above are for when the spray device is in use. It is in. A fourth object of the present invention is to provide a spray device that is highly durable and does not damage the tube as a drug supply means when changing from storage to use or from use to storage. There is a particular thing. The present invention has been made to achieve the above objects,
Tank and nozzle 8! A spray device comprising a side and a connecting mechanism connecting the tank and a discharge port of a nozzle mechanism, wherein at least a part of the connecting mechanism can be maintained in that state without applying a holding force, and A spray device constructed of a flexible material is provided. Incidentally, at least a part of the connection mechanism in the above-mentioned spray device can be configured by a combination of a flexible duplex and a bendable metal material.

【Example】

FIG. 3 is a schematic cross-sectional view of the main parts. In each figure, 11 is a tank filled with a chemical such as a mold remover, 12 is a spray gun type nozzle mechanism, 13 is a chemical discharge port provided at the tip, and 14 is a connection between the discharge port 13 and the tank 11. These are connected tubes, and their structures are basically the same as those proposed so far, so detailed explanations thereof will be omitted. The most important feature of the spray device of the present invention is that it has the structure shown in FIGS. 1 and 2. That is, when using the spray device, the tube 14 can be stretched almost in a straight line or along a predetermined curve, as shown in FIG. When the spray device is not in use, the tube 14 can be wound, for example, in a spiral shape, as shown in FIG. Tube 1 to maintain that state.
4. Note that various methods may be adopted as specific means for constructing such a tube 14, and examples thereof will be explained below. In other words, the 315th! As shown in I, the tube 14 is
The inner tube portion 14m is made of a chemical-resistant and flexible plastic material, and a soft (bendable) core material (wire rod) 14b such as copper or aluminum is placed on the outside of the inner tube portion 14m. A flexible outer tube portion 14e to which a flexible outer tube portion 14e is attached may be provided. When the tube 14 is configured in this way, the core material 14b
Due to the force, the state shown in FIG. 1 is maintained as it is, and due to the force of the core member 14b, the state shown in FIG. 2 is maintained as it is. , and the outer tube portion 14c are bendable, so that the state shown in FIG. 1 can be easily changed from the state shown in FIG. 2, and vice versa. In the case shown in Fig. 1, the features of the spray devices proposed so far can be fully demonstrated, and even in the state shown in Fig. 2, the tube 14 does not get tangled. Moreover, it can be said that there is almost no risk of the tube 14 itself being damaged and becoming unusable, and the above-mentioned drawbacks inherent in conventional spray devices can be solved. . Furthermore, since the tube 14 is bendable and extensible even if the drug is to be supplied to a curved inner part, it is possible to push the tube 14 along a wall, for example, so that the tube 14 can be pushed along a wall. It will also be possible to spray chemicals on In addition to the above-mentioned embodiments, the tube 14 may be constructed without the outer tube portion 14c, for example, if the inner tube portion 14a itself has a certain degree of durability, and in that case, the core material 14b may be replaced with the inner tube portion. It may be buried within the peripheral wall of 14a or attached to the outside;
The tube 14 may be obtained by removing the inner tube portion 14a in the figure.
