Description

Technical field of the invention

The present invention relates to a fluid spouting nozzle and a fluid spouting apparatus which is easy to operate and is possible to be compactly manufactured, more particularly, it relates to a fluid spouting nozzle and a fluid spouting apparatus which spout two kinds of fluid that are necessary for washing or painting, for example the gas and the liquid, simultaneously while making a rotation and spread in some range.

Description of the Prior art

A fluid spouting apparatus used for cleaning removes a dust, dirt and so on that should be cleaned by spouting a gas such as compression air from a spouting opening of a spouting nozzle.
And, fluid spouting apparatus used for washing apparatus removes a dust and wash off the dirt by spouting a liquid or a powder formed or granular polishing agent from a spouting opening of a spouting nozzle with a high-pressure air.
Therefore, a conventional fluid spouting nozzle or spouting apparatus has a structure that makes spouting fluid to be pushed and spouted with a high-pressure air from the upper stream of the pass connecting to the nozzle.
This structure is also adopted to the invention disclosed by tokkaihei 11-123350 which shows the characteristic spouting nozzle formed by a flexible cylindrical material which allows the nozzle to move a gyration (turning-over movement) and the spouting fluid to be jetted out with circulation and diffusion following to the said movement of the nozzle.
The washer apparatus described in tokkaihei 2000- 51800 similarly uses the above mentioned characteristic spouting nozzle which moves a gyrating motion caused by flexibility of a material of nozzle itself when the spouting fluid jet out from the nozzle. As roughly shown in Fig5, this washer apparatus equipped with a water supplying source A, a compression air supplying source B, a detergent supplying source C, a spouting nozzle E, and a pipe road F (it comprises branching pipe road F 1 ~ F 3 on the upper stream and supervision road F4 on the downstream) which connects the every supplying source A - C to the spouting nozzle E.
In this apparatus, compression air is sent into the water-supplying source A and the detergent supplying source C, by the compression air supplying source B. By operating the switching means D set on a connection parts with supervision road F 4, the fluid in the branching pipe road Flu F3 is chosen and water or detergent or compression air is spouted from the spouting nozzle F.
However, as represented by the above-mentioned tokkaihei 2000 - 51800, the conventional apparatus has a structure to send compression air into a supplying source A, C of spouting fluid such as water and detergent and to supply water or detergent with pressure to the spouting nozzle E.
Therefore, as for the conventional apparatus, it has to use a strong powered compression air supplying source B, a water supplying source A and detergent supplying source C also get large, and consequently the whole apparatus gets big.
And, as for the conventional apparatus, a structure of a spouting nozzle is formed like a gun shaped (numeral E' in Fig. 5) loaded an aforementioned switch means considering a handling. But, because three pipe road F1 ~ F3 are supposed to be connected with this structure E', these pipe roads are troublesome to handle the gun shaped structure of a spouting nozzle, and it is difficult for nozzle E to work for washing.
Further, to change spouting fluid into some different liquid, it must convert a tank itself of supplying source A,C.
Hence, an object of the present invention is to provide a fluid spouting nozzle and spouting apparatus that can make the whole apparatus compact, that can be easily operated, and that can easily exchange a spouting fluid also.

Summary of the invention

In order to achieve the above-mentioned object, this invention equips the following configuration.
That is, the fluid spout nozzle according to Claim1 is equipped with an outer nozzle and an inner nozzle inserted into the outer nozzle. Both nozzles are made of the pipe material having flexibility and moreover their tip part is free without being fixed. Said outer nozzle has a flowing path among the inner nozzle. The flowing path communicates with a pressurization gas-supplying source at the back end portion and owns a gas spout opening at the front-end portion. The inner nozzle has an inner passage. The inner passage communicates with a supplying source of the secondary medium that consists of liquid, powder grain, or the mixture of liquid and the powder grain at the back end portion. And it owns the secondary medium spout opening at the front-end portion. The spout opening for secondary medium is arranged to be located in the negative pressure area that is formed in said gas spout neighborhood when gas is spouted from the gas spout. And at least the front portion of the inner nozzle and the outer nozzle including the both spout openings act gyrating movement when gas is spouted out from the gas spout via the flowing path. Simultaneously with this, the secondary medium is sucked from the supplying source through the inner passage and is spread out in the mixing condition with said gas.
The spout apparatus according to Claim13 is the one applied the fluid spout nozzle according to Claim 1.
This spout equipment is equipped with the pressurization gas-supplying source in addition to the composition of the fluid spout nozzle of Claim1. And also, it is equipped with the supplying source of the secondary medium for the spout that consists of liquid, powder grain, or the mixture of liquid and the powder grain.
It is desirable to install the balancer that helps the gyrating movement of the outer and inner nozzle on the peripheral surface of outside the nozzle for the present invention.
The balancer is installed on the front-end periphery of the outer nozzle and so on in the number of single. Or it is provided in one more than at the peripheral surface of the outer nozzle with some interval along the length direction of the outer nozzle.
Also, the regulation member that limits the gyrating movement of the nozzle should be provided in the present invention. The regulation member may be formed in the spread trumpet shape and surrounds the whole portion acting the gyrating movement of the outer and inner nozzle or may consists of a ring member that surrounds partially the portion acting the gyrating movement of the outer and inner nozzle.
A whisk may be provided at the front-end of the regulation member depending on need. The hair of the whisk wavers by the turning spout flow.
The outer nozzle and the inner nozzle consist of the synthetic resin or rubber tube having flexibility. The outer and inner nozzle may be deferent material each other.
The concrete or definite kind of pressurization gas and the secondary medium for the spout is appropriately chosen depending on the purpose of the nozzle and the spout equipment of the use.
For example, pressurization gas is the compression air that is sent pressurized from the source of supply of the compressor and so on. The secondary medium is liquid for washing, paint, or a powder grain for polishing. Liquid for washing may be the mixing liquid of the detergent and the scourer.
The compression air source likes a compressor or an aerosol typed source and the flowing path is communicated with a primary communication path.
An opening and shutting means is provided in the primary communication passage. The opening and shutting means and the nozzle should be united in the spout nozzle mechanism with the gun type.
The secondary medium supplying source should be composed by a receptacle of the secondary medium such as wash liquid. The second communication path, being free in opening and shutting, communicates the receptacle for the secondary medium and the inner passage of the inner nozzle.
The receptacle is connected to the spout nozzle mechanism such as the gun-type one, being free in attaching or removing. The second communication path communicates the inner passage of the inside nozzle for the secondary medium.
According to the present invention, pressurization gas is spouted out from the gaseous spout in the tip part via the flowing path of the outer nozzle from the primary communication path. The secondary medium is spouted out from the secondary medium spout of the inner nozzle via the inner passage of the inner nozzle.
The secondary medium isn't sent pressurized. It is automatically sucked out of the secondary medium spout in the negative pressure that occurs to the gaseous spout neighborhood with spout of gas. Sucked secondary medium is spread in the front, riding the flow of the gas that is spouted out like whirlpool with the gyrating movement of the nozzle.

Embodiment Mode of the Invention

An embodiment of the invention is described with reference to the drawings as follows.
Fig. 1 shows a partial section rough view of a fluid spouting apparatus for cleaning according to the embodiment. Fig. 2 shows an enlarged cross section view of the nozzle portion.
This fluid spouting apparatus includes a fluid spouting gun 1, pressurization air supplying source 2, and receptacle (storage case) 3 for washing liquid.
Fluid spouting gun 1 has a nozzle 6 being installed at the tip portion of the gun body 4 by means of the connecting member 5. A connecting member 4 has a passing route 7 in the inside to allow gas to pas. At a lower portion of an outside surface of a connecting member 5, a connection hole communicating to a passing route 7 is formed. Washing liquid storage case 3 is freely connected with the connection hole 8, by means of valve operation member 9.
At the front-end of the connecting member 5, an installation member 11 for nozzle 6 is fixed. An installation member 11 has penetration hole 12 at the inside portion.
At the front-end of the installation member 11 for nozzle 6, a base end of the outer nozzle 13 is fixed. In the inside of the outer nozzle 13, inner nozzle is inserted.
A gap causing between an inner-surface of the outer nozzle 13 and an outer-surface of the inner nozzle 14 forms a gas flowing path 15. This flowing path 15 communicates with the passing route 7 of the connecting member 5 through the penetration hole 12 of the installation member 11. A rear portion of the inner nozzle 14 entering into the passing route 7 of the connecting member 5 from the penetration hole 12 extends to the connection hole 8 of the connecting member5, hence is connected to an operation member 9 for opening and closing a valve. A passage 16 is composed of the passage for washing liquid.
The outer nozzle is made of plastic tube having flexibility, example for nylon, Teflon, polyurethane, and polypropylene. Inner nozzle 14 is also made of the same material at least of a portion inserted in the outer nozzle 13.
As accompanying gas passes in the flowing path 15 between the outer nozzle 13 and the inner nozzle14 and jets out from the spouting opening 15a provided at the top end of the flowing path, the front portion of the outer nozzle 13 and inner nozzle 14, extending ahead of the fixed base end of the outer nozzle 13, rotates in a gyrating or turning-over movement because of the flexibility of it's own.
A spouting opening 16a being at the end of the inner nozzle passage 16 thrusts out to an outside area of the spouting opening 15a being at the end of the outer nozzle flowing path 15, that is a negative pressure area formed around a spouting opening 15a neighborhood when gas is spouted out through the flowing path 15.
At an outer surface of the outer nozzle, balancers 17 made of plastics are attached to the top end portion of the outer nozzle 13 and some appointed portions along a length direction of the outer nozzle with some intervals. Balancers 17 give a inertia power to the said gyrating movement and make that movement more effectively.
Outside portion distant from the outer nozzle 13,a control guide member 18 for restricting a gyrating movement of the nozzle is provided, which is formed trumpet shape having a large diameter. The Control guide member is made of plastics materials. A front opening edge of the control guide member 18 is projecting from the top end of the nozzle 6. And it makes the nozzle 6 to rotate a gyrating movement along an inside surface of it. Thus, a rotation movement is restricted in certain range in diameter direction and gas is spouted along the front opening edge 18a of the control guide 18.
An air compressor is used for the pressure air-supplying source 2 which is connected with for gun body 4 by means of supply pipe 19. Gun body 4 makes pressure air to send into the passing route 7 of the connecting member 5 from the pressure air-supplying source 2 when a lever for trigger 20 of the gun body 4 is pulled.
Pressure air sent into the passing route 7 invades to the flowing path 15 of the outer nozzle 13 by way of the penetration hole 12 from the passing route 7.
While the trigger 20 is pulled, the route between the supply pipe 19 and the passing route 7 and the route between the penetration hole and the flowing path 15 of the outer nozzle 13 are maintained a connecting condition. And when the trigger 20 is returned, the route between the supply pipe 19 and the passing route 7 is blocked.
Detergent liquid receptacle 3 is attached to an adequate portion of the upper stream of the opening and shutting valve operation member 9 which was connected with the said connection hole 8 of the connecting member 5, being free in the attaching or removing.
Receptacle 3 stores up detergent liquid without pressurizing it. Insertion pipe 21 connected to the base portion of the inner nozzle 14 through the opening and shutting valve operation member 9 extends to the bottom of receptacle.
Incidentally, numeral 10 is an operation lever of the opening and shutting valve operation member 9, 22 is a hole part formed at the required position of regulation guide 18 for rotation of the nozzle, 23 is a cover body of receptacle 3, and 24 shows a main body of the receptacle. As for the attaching or removing mechanism of receptacle 3, suitable means such as the screw type, the putting-in type are adopted.
With the configuration as described above, when this apparatus attempts to spout out pressurization air and detergent liquid at the same time, the detergent liquid receptacle 3 is attached to the gun body at the first time. And the operation lever 10 of the opening and shuttering valve operation member 9 is set to an opening position to make let through insertion pipe 21 and the inner nozzle 14.
Next, the compressor as a pressurization air source of supply 2 is driven. When the trigger 20 of gun body 4 is pulled, compression air flows through the flowing path 15 of outer nozzle 13 via supply pipe route 19, passage route 7, piercing route 12 from the compressor 2. A ream of continuing route with flowing air composes the primary communication path. The compression air flowed into the said route is forcefully spouted out from the spout 15a which is in the tip in the flowing path 15. At this time, the outer nozzle 13 and the inner nozzle 14 make the freedom end (not fixed) of the nozzle that has spout 15a act violently and make it do movement in the turning-over. Because, the back portion of the both nozzle is fixed and the front portion including the freedom end of the both nozzles 13,14 is formed by the flexibility synthetic resin material. This gyrating movement is limited to the constant range in the direction of the diameter by the regulation guide 18 which was provided in outside of the outer nozzle 13. Thus, the front portion of the nozzle rotates in a regular gyrating movement along the inside of regulation guide 18. And, the balancer 17 installed around the outside of the outer nozzle 13 makes a gyrating movement of the nozzle become stable.
When air is forcefully spouted out from the flowing path 15 of the outer nozzle 13, the negative pressure acts on a spout (16a) at the inner passage 16 of the inner nozzle 14. Detergent liquid in the receptacle 3 is sucked up via the passage 16 of the inner nozzle 14 and an insertion pipe 21 by the negative pressure. This route in which the detergent liquid flows through composes the 2nd communication path.
Then, detergent liquid rides on air spouting from outer nozzle 13 and is spread like a fog in the mixing condition with air. The outer nozzle 13 and the inner nozzle 14 spout out air or detergent liquid while they act the gyrating movement. Therefore, the mixing fluid of air and detergent liquid is spouted out in a whirlpool flowing with amplified force and collide with the surface to be washed in rubbing condition. As described above, the gyrating movement of the nozzle 6 is limited with the regulation guide 18 in a constant range. Also, the movement of the nozzle 6 adds the centrifugal force to the spouting power of the mixing fluid of air and detergent liquid. Therefore, the spout flow from the nozzle acting a gyrating movement can gain a strong wash power compared with the spout flow from a fixed nozzle, which is only spout out to a front direction in the figure of straight line.
As for the fluid spout gun, because only a single supply pipe route 19 is connected with the gun body 4, the pipe route never cause troublesome in spouting work. Also, because the detergent receptacle 3 is situated between gun body 4 and nozzle 6, the handling balance of gun body 4, too, becomes good.
When changing or replenishing detergent liquid, it needs only to attach a new receptacle 3 of different detergent liquid or replenished detergent liquid after removing the former receptacle.
When the operation lever 10 of the opening and shutting valve operation member 9 is set on closed position and the trigger lever 20 of gun body 4 is pulled, as described above, the compression air sent from compressor 2 passes through the flowing path 15 of outer nozzle 13 via passage route 7 and piercing hole 12, and it spouts out from the spout opening 15 provided for the tip in flowing path 15. On the other hand, detergent liquid insertion pipe 21 is blocked off not to communicate with the inner aisle 16 of the inner nozzle 14 by opening and shutting valve operation member 9. Therefore, while outer nozzle 13 and the inner nozzle14 act movement in the turning-over, the nozzle 6 spread the whirlpool flowing consists only of air
Such a whirlpool flowing only of air is effective to blow and to remove dust as the pre- processing of a wash and light adhesion one. Also, it is useful for the dry processing of the object after the blowing of detergent liquid and the applying for paint, too.
Fig. 3 is the part section schematic that shows the fluid spout apparatus for another embodiment of this invention.
This apparatus has the same basic structure of the fluid spout apparatus shown in figure 1. In addition, an annular whisk 30 is installed along the end 18a of the opening of the regulation guide 18 prepared for the nozzle 6. The hair of the annular whisk 30 is planted along the direction of the axis line of the regulation guide 18.
Incidentally, note that in the description of this embodiment in Fig. 3, the same components as those in the embodiment described in Fig.1 are indicated with the same reference numerals and duplicated description are omitted.
The mixing fluid of the air and the wash liquid which was spouted out from the inner nozzle 14 and the outer nozzle 13 turning over according to the internal circumference of regulation guide 18 is spouted out to the direction where the diameter spreads from the end 18a of the opening along the internal circumference surface of regulation guide 18.
Each hair 31 of the annular whisk 30 which is spread along the direction of the axis line of regulation guide 18 is bent over to the direction of the diameter of the regulation guide 18 when the spouted mixing turning-over fluid collides with it, and returns to the origin position when the turning-over fluid gets not to hit it.
Therefore, the hair 31 of annular whisk 30 makes change a distorted position into the direction of the diameter in order according to the turning flow movement of the mixing fluid. The position to be made to change turns over like the turning-over flow.
When making whisk 30 touches the surface to be washed, the surface is washed without patches in the gyrating movement of the hair of the whisk 30, which is bent into the direction of the diameter and same gyrating movement of spouting mixing fluid flow.
In two embodiments described above, wash liquid was used as a medium spouted out from the inner nozzle. However, in this invention, the medium spouted out from the inner nozzle isn't limited to this. The granular or floury scourer of the diameter for which it is possible to pass through the inner passage 16 can be used for this invention, too.
A scourer is used in the condition independent or to be mixed with liquid.
A scourer is housed in the receptacle which is installed in the gun body of the fluid jet gun, being free in the attaching or removing, like the embodiments described above.
In this invention, as the supplying source of pressurization gas, the compression air supply container of the aerosol type can be used, too. In this case, the connecting member 5 as shown in Fig.1 and Fig.3 is connected to the nozzle member in the upper part of the compression air supply container. And, the nozzle 6 and the receptacle 3 of the secondary medium described in this invention are fixed to the connecting member 5. Fig. 4 shows the concept composition of it. In the description of this embodiment in Fig.4, the same components as those in the embodiment described in Fig.1 and 3 are indicated with the same reference numerals and duplicated description are omitted.
In this embodiment, small receptacle is used. And a fluid jet gun isn't used. The aerosol type condensation air supply container 41, which has nozzle member 40, is used for the change of the fluid jet gun. This embodiment provides more compact-sized apparatus compared with the one that uses a compressor and a fluid jet gun.
However it doesn't illustrate, in this invention, a bypass on the halfway of the flowing path of the outer nozzle may be provided. And a valve to change a flow to the bypass side may be prepared to make suction power act on the spout of the outer nozzle. Moreover, by setting up the 2nd bypass on the halfway of the flowing path, the dust to have sucked from outer nozzle spout is led into the 2nd bypass and can be collected.
The regulation guide member is the one to limit the gyrating movement of the front portion of the nozzle in the some constant range in the direction of the diameter. Therefore, for example, the regulation guide member can be composed by the member, which covers the outside of outer nozzle like a ring, keeping a required gap, too.

[Effects of the invention]

The present invention causes the following effects.
In the invention composed in Claim 1, since the negative pressure is created around the spout of the inner nozzle when gas spouts out from the outer nozzle, it is possible to make a secondary medium spout from the secondary medium source of supply in the mixing condition with gas by sucking force.
Therefore, the present invention can spout the mixing fluid from the nozzle without pressurizing a secondary medium. Moreover, it is possible to make the secondary medium spread and diffuse by mixing it in the atomization in gas by the spout power of gas.
Since the outer nozzle and the inner nozzle act the gyrating movement when gas passes the flowing path of outer nozzle, this invention can spout the mixture of the secondary medium and gas forming turning-over flow. The turning-over flow is very effective in cleaning or washing because it makes rub a target surface when touching a target.
When providing the member for regulating the gyrating movement of the nozzle at the outside of the outer nozzle, the nozzle turns over along the inner surface of the regulation member. By this construction, the fluid flow that spouts from the nozzle can be spread in the constant range.
Forming a regulation member in trumpet-shape and attaching an annular whisk at the opening end of the regulation member, the hair of the whisk will bent in order when the spout flow of gas and so on touches it, and it will restore to the original position when the spout flow passes over. By this construction, the surface of the object can be uniformly rubbed without patches with the hair of the whisk.
According to the apparatus invention of claim 13, it does not need to add pressurization means to the supplying source of the secondary media such as detergent liquid and can compact-size the whole of the apparatus, in addition to the effect of the invention of Claim1.
Also, since only a gas supply pipe route is connected to the spout nozzle as a supply pipe route, the present invention can provide an apparatus to operate a spout nozzle easily.
And moreover, since a receptacle can compose the supplying source of the secondary medium, the secondary medium can be easily exchanged.
