Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an aerosol device for cleaning pipes.

More specifically, the present invention relates to an aerosol device that is used to spray cleaning liquid into the inside of a drain pipe or the like in order to clean the inside of the pipe.

[Prior Art] Until now, there have been no aerosol devices specifically designed for cleaning the interior of drain pipes and the like.

Therefore, conventionally, for convenience, an aerosol device having a relatively long and narrow spout has been used, and the spout is inserted into the interior of the drainage tube through the mouth to spray the cleaning liquid.

[Problems to be Solved by the Invention] FIG. 7 shows the usage state of the conventional aerosol device. In the figure, C is an aerosol device, W is a wash basin, and P is a drain pipe. The cleaning liquid injected from the nozzle n of the aerosol device C reaches a certain distance l from the tip of the nozzle n, but does not reach very far from there. Further, when the drain pipe P is bent in the middle, the cleaning liquid does not reach beyond the bent part. Therefore, there is a problem in that the conventional aerosol device C can only clean the area close to the opening of the drain pipe P.

In view of these circumstances, the present invention provides an aerosol device that can clean deep inside the drain pipe.

[Means for Solving the Problems] The pipe cleaning aerosol device of the present invention includes a cylindrical container, a valve provided at the upper end of the container, a spout connected to the valve, and a tip of the spout. A structure consisting of a highly flexible tube connected to the tube and a weight having a nozzle attached to the tip of the tube is adopted.

[Operation] Since the weight of the present invention is connected to a highly flexible tube, it can freely penetrate deep into the interior of a drain pipe that has a curved part due to the action of gravity. Therefore, if the cleaning liquid is passed through the tube and the weight and is injected from the nozzle of the weight, the interior of the drain pipe can be deeply cleaned. By changing the length of the tube depending on the length of the drain pipe, you can freely change the depth of cleaning.

[Example] Next, embodiments of the present invention will be described.

Fig. 1 is a perspective view of the aerosol device A of the first embodiment, Fig. 2 is a front view of the same embodiment in the usage position, Fig. 3 is an explanatory diagram showing the tube in the retracted state, and Fig. 4 is the same embodiment. FIG. 5 is a front view of the main part of the aerosol device B of the second embodiment in the usage position, and FIG. 6 is an explanatory diagram showing the state in which the tube is stored.

In FIGS. 1 and 2, 1 is a cylindrical container;
2 is a spout, 3 is a tube, and 4 is a weight.
The container 1 is a pressure container made of metal such as aluminum or tin, and contains an alkaline agent, a surfactant, a disinfectant, water, etc. as a drain pipe cleaning agent together with a propellant. The size of this container 1 is usually 40 to 70 mm in outer diameter, 100 to 300 mm in length, and 100 to 300 in capacity so that it can be held and operated by hand.
It is made around 1000ml.

A mounting cap 14 is attached to the upper end of the container 1.
is fixed, and a valve (not shown) is mounted by means of its mounting cap 14. The valve has a stem 15 and opens when the stem 15 is pushed down or tilted.

The lower part of the spout 2 is fitted into the stem 15, and the tube 3 is connected to the spout 2. Note that the tube 3 and the valve are communicated through an internal passage of the spout 2.

The spout 2 is an elongated cylindrical member,
It is connected to a cap 18 via a connecting piece 17. Spout 2 on the opposite side of the connecting piece 17
A trigger 19 is formed near the base end of the trigger 19, and when the trigger 19 is pressed downward with a finger, the connecting piece 17 is bent, the stem 15 is pushed down, and the valve is opened. Note that a slit-like notch 21 is formed at the tip of the spout 2.
Furthermore, a tapered seat 22 for inserting the weight 4
is formed. The cap 18 is a ring-shaped member, and the mounting cap 1
It is elastically fitted and fixed to the upper end of 4.

The tube 3 has sufficient flexibility and can be bent freely, and is made of synthetic resin such as polyethylene, polypropylene, polyvinyl chloride, or the like. Its length is
Although it is appropriately selected depending on the length of the drain pipe to be cleaned, it is also limited by the extrusion pressure of the container 1, so a length of 50 to 300 mm is usually used.

A weight 4 is connected to the tip of the tube 3. In order to make it easier for the weight 4 to enter the drain pipe by gravity, a shape consisting of a conical tip and a truncated conical base is adopted, and the weight is 5 to 50 g. It can be used preferably. Weight 4
Although there are no particular restrictions on the material, metals such as steel, stainless steel, and brass may be used. A nozzle 4a is formed inside the weight 4 so as to communicate with the tube 3. This nozzle 4a is opened laterally and is designed to be able to spray the cleaning liquid directly toward the wall inside the drain pipe.

With the above configuration, when the trigger 19 is pressed with a finger, the valve opens and the cleaning liquid in the container 1 is poured into the tube 3.
It is ejected from the nozzle 4a of the weight 4 to the outside through the nozzle 4a of the weight 4.

Note that when the aerosol device A of this embodiment is not in use, the tube 3 is wound around the outer periphery of the spout 2, and the weight 4 is
can be inserted into the seat 22 at the tip of the spout 2 and stored compactly. Next, the operation of this embodiment will be explained.

When using the aerosol device A of this embodiment, as shown in FIG. 4, the weight 4 is slid into the drain pipe P and the tube 3 is deeply inserted. When the trigger 19 is pressed in this manner, the cleaning liquid in the container 1 is sprayed from the spout 4a provided in the weight 4 toward the wall surface of the drain pipe P. To change the position in the drain pipe P where the cleaning liquid is sprayed, all you have to do is move the container 1 in your hand up and down.
It is possible to reliably clean from the vicinity of the opening to deep inside.

Next, an aerosol device B according to a second embodiment will be explained based on FIGS. 5 and 6.

In FIGS. 5 and 6, 1 is a container, 2 is a spout, 3 is a tube, and 4 is a weight. The container 1 is a pressure container similar to that of the first embodiment, and at its upper end, a spout 2 is connected to a cap 18 by a connecting piece 17 with the same configuration as that of the first embodiment, and when a trigger 19 is pushed in, a valve is opened. opens the spout 2,
The cleaning liquid is sprayed from the nozzle 4b of the weight 4 via the tube 3.

The above configuration is substantially the same as the first embodiment except for the shape of the spout 2 and the shape of the weight 4. In this embodiment, the tip of the spout 2 is provided with a first protrusion 23 that protrudes laterally, and the base of the spout 4 is provided with a second protrusion 24 that is prismatic and protrudes laterally. The configuration of the tube 3 is similar to that of the first embodiment. In this embodiment, the weight 4 is formed into a spherical shape, and is provided with a nozzle 4b. This nozzle 4b is formed in a similar shape to the second protrusion 24 so that it can be firmly inserted into the second protrusion 24.

In this embodiment, when the aerosol device B is not used, as shown in FIG.
The tube 3 can be wound around the second protrusion 24, and the nozzle 4 of the weight 4 can be inserted into the second protrusion 24 and stored. Also in this aerosol device B, similarly to the first embodiment, the weight 4
By inserting it into the drain pipe and spraying the cleaning liquid, you can clean deep inside the pipe.

As described above, the present invention can be applied to cleaning any pipe that extends downward, such as the drain pipe of a washstand or kitchen sink.

The present invention has been explained above by giving two examples,
Various modifications can be made to the present invention without changing the gist thereof. For example, in the embodiment described above, a substantially conical or spherical weight 4 was used.
Weights of various shapes can be employed without being limited to these.

[Effects of the invention] According to the invention, since the highly flexible tube and the weight are used to spray the cleaning liquid even into deep places, it is possible to thoroughly clean the inside of the tube.
