Description

  The present invention relates to a liquid agent dilution sprinkling device having a so-called ejector jet pump structure that sucks a liquid agent such as liquid fertilizer by generating negative pressure and dilutes it with water supplied from a water supply facility.

In the field of horticulture and agriculture, liquid fertilizer, agricultural chemicals and other chemicals have been diluted and sprayed in water supplied from water supply facilities such as water supply.
Moreover, when washing a car such as a private car at home, it has been practiced to dilute a detergent for washing with water and spray it.
Conventionally, in order to dilute a liquid agent other than water widely and spray it, a liquid agent dilution sprinkler has been used.

The liquid agent dilution sprinkler of Patent Document 1 has a connection port for introducing water from a water supply facility via a hose and the like, and a water spray port for discharging the water, and water is internally supplied from the water introduction port to the water spray port. It was formed as a watering nozzle provided with a main flow path passing through.
In this liquid agent dilution sprinkler, a liquid agent container containing a liquid agent is detachably attached to the lower part by screw connection. The inside of this liquid agent container was connected to the liquid agent dilution part which is a confluence | merging part with the main flow path by the liquid agent flow path which consists of a hose and a pipe | tube.
In the liquid agent dilution section, the main flow path has a reduced diameter on the upstream side and an enlarged diameter on the downstream side, so that negative pressure is generated when water flows and the liquid agent is sucked from the liquid agent container and diluted to water. I was able to.

However, in the liquid agent dilution sprinkler of Patent Document 1, since the liquid agent container is directly attached to the lower part of the water nozzle, the water nozzle becomes heavy and difficult to handle with one hand. In addition, the liquid agent container is integrally attached to the watering nozzle, and the apparatus becomes large and difficult to handle, and it is difficult to spray water in a narrow area such as a potted plant.
In addition, the screw connection between the female screw formed on the water spray nozzle and the male screw formed on the liquid agent container fixed the water spray nozzle and the liquid agent container, so that the screw connection is loosened due to vibration during use, and the liquid agent container is detached. There was a fear.
Furthermore, since the load is always concentrated on the screw coupling portion, which is a fixed portion between the watering nozzle and the liquid container, the coupling portion may be damaged due to stress over time or instantaneous impact.

In Patent Document 2, a liquid agent dilution unit provided on the base end portion of the water spray nozzle is provided by a user holding the liquid agent container on the shoulder and supplying the liquid agent by a hose interposed from the liquid agent container to the base end portion of the water spray nozzle. Describes a liquid agent dilution sprinkler for diluting a liquid into water and spraying water.
The structure of the liquid agent dilution part for diluting the liquid agent with water is substantially the same as that of Patent Document 1.

However, the liquid agent dilution sprinkler of Patent Document 2 has two systems of hoses: a hose that supplies water from the water supply facility to the watering nozzle and a hose that supplies the liquid agent from the liquid agent container to the watering nozzle. The handling of the user was worsened by entanglement.
In addition, if the hose connecting the liquid container with the watering nozzle is broken or twisted during use, the amount of liquid sucked is reduced, and a predetermined dilution concentration cannot be achieved. When a hard hose is used to prevent this, there is a problem that the handling of the user is further deteriorated.
Since the liquid container and the liquid dilution part are far apart via a hose, the negative pressure required to draw the liquid increases, and the liquid starts to dilute through the hose after the watering nozzle starts watering. There was a problem that it took time to be done.

Furthermore, since the liquid agent dilution part was formed in the base end part of the watering nozzle, the watering nozzle became larger and heavier, making it difficult to handle.
Moreover, since the liquid agent dilution part was incorporated in the watering nozzle, it was not possible to perform the liquid agent dilution spraying on devices other than the watering nozzle such as a sprinkler.

Hereinafter, the liquid agent dilution sprinkler 1 according to the first embodiment of the present invention will be described.
This liquid agent dilution sprinkler 1 can be used for various uses for diluting and spraying horticulture, agriculture, car washing, cleaning, and other liquid agents.

As the liquid agent, horticultural or agricultural liquid fertilizers and insecticides, herbicides and other agricultural chemicals, car wash or cleaning detergents, chemicals, and other liquids other than water can be used. In addition, those liquids previously diluted with water to a certain concentration are also included.
As a solvent for diluting the liquid agent, water supplied from a water supply facility such as a water supply is typical, but other solvents may be used. This solvent may be, for example, mixed water in which a substance other than the liquid agent diluted with the liquid agent dilution sprinkler is previously dissolved in water.

  As shown in FIGS. 1 and 2, the liquid agent dilution sprinkler 1 includes a diluter body 2 that dilutes the liquid agent into water introduced from a water supply facility (not shown), a liquid agent that is stored in the diluter body 2. It consists of a liquid container 3 that is detachably attached and a watering nozzle 5 that is connected to the diluting device body 2 via a hose 4 and that sprays water in which the liquid is diluted.

As shown in FIGS. 3 and 10 (a), the diluting device body 2 has a water inlet 6 for introducing water, a water outlet 7 for leading water introduced from the water inlet 6, and a water inlet. A main channel 8 through which water passes from the port 6 to the water outlet port 7 is formed.
As shown in FIGS. 1 and 2, the watering nozzle 5 includes a connection port 9 connected to the water outlet 7 by the hose 4, a watering port 10 for discharging water flowing in from the connection port 9, and a connection port 9. It has a nozzle flow path that allows water to pass to the water spout 10 and a nozzle water stop valve 11 that is arranged in the nozzle flow path and switches between water flow to the water spout 10 and water stop.

The water supply facility is not particularly limited, and may be water supply from a tap of a water supply, water supply from a well or a water storage tank, and the like.
As shown in FIG. 10, the water introduced into the diluting device main body 2 from the water introduction port 6 passes through the main flow path 8, and after the liquid agent is diluted by the liquid agent dilution section 12 provided in the middle, 7 is sent to the watering nozzle 5 and sprayed from the watering port 10 of the watering nozzle 5.

<Dilution device body>
Hereinafter, the dilution apparatus main body 2 will be described in detail.
As shown in FIG. 3 and FIG. 10, the diluting device main body 2 incorporates a main flow path 8 through which water passes and houses a liquid container 3 in the lower portion to dilute the liquid into water at a predetermined magnification. Then, it is sent to the watering nozzle 5.

As shown in FIGS. 3 and 4, a hose 4 or the like (not shown) is connected to the upper portion of one side surface of the diluting device body 2 to introduce water from an upstream water supply facility (not shown). A hose nipple 13 in which the introduction port 6 is formed is projected.
A hose connector 14 in which a water outlet 7 for leading water is formed is formed on the upper part of the opposite side surface of the diluter body 2.
The water inlet 6 and the water outlet 7 are connected by a main flow path 8 that penetrates the inside of the diluter main body 2 from right to left in FIGS. 4C and 10A.

The lower liquid agent container storage part forms a space (liquid agent container storage part) for storing the liquid agent container 3 therein, and the front part of this space is cut out for taking in and out of the liquid agent container 3 and above the rear part. It is formed as a housing with an opening in half.
The left and right side portions and the rear portion of the liquid container storage section have a function of covering the liquid container 3 to be stored and protecting it from an impact or the like.
The liquid container 3 does not need to be entirely stored in the liquid container storage part, and a part thereof may be exposed or protruded from the liquid container storage part.

Further, a base 15 that is expanded more than the liquid agent container storage part is formed below the liquid agent container storage part to prevent the dilution apparatus main body 2 from falling.
As shown in FIG. 3A, the center portion of the base 15 is cut out in a circular shape so that leakage water and dust do not collect.

The left and right width of the base 15 is preferably 80 to 400 mm.
If it is less than 80 mm, the main flow path 8 becomes too short, and it becomes difficult to provide the liquid agent dilution part 12. The thickness is more preferably 100 mm or more, and particularly preferably 120 mm or more.
On the other hand, if it is larger than 400 mm, the diluting device main body 2 becomes large and difficult to carry and handle by the user's hand. More preferably, it is 350 mm or less, and particularly preferably 300 mm or less.
For the above reason, the left and right width of the base 15 is 180 mm in the first embodiment.

The depth of the base 15 is preferably 60 to 400 mm.
If it is less than 60 mm, the main flow path 8 becomes too thin and it becomes difficult to provide the liquid agent dilution part 12, and only the small liquid agent container 3 can be used. It is more preferably 80 mm or more, and particularly preferably 100 mm or more.
On the other hand, if it is larger than 400 mm, the diluting device main body 2 becomes large and difficult to carry and handle by the user's hand. It is more preferably 300 mm or less, and particularly preferably 250 mm or less.
For the above reason, the left and right width of the base 15 is set to 118 mm in the first embodiment.

As shown in FIGS. 3 and 6, the diluting device body 2 can be divided into an upper member 16 and a lower member 17 at the height of the liquid container storage portion.
The upper member 16 and the lower member 17 are integrally fixed by a lever fixing tool 18 and can be disassembled by removing the lever fixing tool 18. When the liquid agent container 3 is attached to the diluting device body 2, the upper member 16 and the lower member 17 are disassembled, the liquid agent container 3 is sandwiched therebetween, and the diluting device body 2 is assembled integrally by the lever fixing tool 18. .

As a material of the diluting device main body 2, plastic, metal, or glass can be used.
Among these, plastics or metals such as stainless steel, brass, zinc, and aluminum are preferable because they are lightweight and suitable for carrying, have little deterioration such as rust, are not easily broken, and are easy to process. In addition, plastic is particularly preferable because raw materials and production costs are low.
In the first embodiment, plastic is used for the above reason.
If liquid agents that cause rust, corrosion, chemical stress cracks, etc. are planned, the main flow path 8, the liquid flow path 19 (see FIG. 10), and other components of the diluting device main body 2 are resistant to chemicals. It is desirable to use a material with excellent properties.

As shown in FIG. 6, in the dilution apparatus main body 2, a container mounting portion 20 for connecting the liquid agent container 3 is formed above the liquid agent container storage portion.
As shown in FIG. 6 (b), the container mounting portion 20 is formed in such a diameter that it can be inscribed in the mouth of the tip of the liquid container 3 and can be held by a frictional force.

Further, as shown in FIG. 7B, an annular O-ring 21 made of an elastic material may be provided around the outer peripheral surface of the container mounting portion 20 as a separation preventing portion for the liquid agent container 3.
When the tip of the liquid container 3 is inserted into the container mounting portion 20, the O-ring 21 abuts against the inner peripheral surface of the liquid container 3 while being elastically deformed, and the liquid container 3 is moved by the elastic force and frictional force of the O-ring 21. It can hold and prevent separation.
By providing the O-ring 21 as a detachment preventing portion, the liquid agent container 3 is firmly attached to the container attachment portion 20 even when the dimensional accuracy of the outer peripheral surface of the container attachment portion 20 or the inner peripheral surface of the liquid agent container 3 is not so high. Can be attached.

The diameter (outer diameter) of the O-ring 21 is preferably 5 to 80 mm.
If the diameter is set to less than 5 mm, the diameters of the liquid agent introduction port 22 and the straw tube 23 described later must be set small, and the liquid agent cannot be sufficiently sucked.
If the diameter is set to be larger than 80 mm, the mouth of the liquid container 3 and the diluting device main body 2 are increased in size, and the liquid container 3 is difficult to attach and detach.
The diameter is more preferably 10 to 50 mm, and still more preferably 17 to 22 mm. For the above reason, the O-ring 21 having a diameter of 19 mm is used in the first embodiment.

Rubber or elastomer can be used as the material of the O-ring 21.
Since it is preferable to prepare a plurality of kinds of standards having different capacities and shapes for the liquid agent container 3 attached to the diluting device main body 2, it is preferable that the O-ring 21 can also prepare a plurality of standards in accordance with these. For this reason, in this embodiment, a rubber O-ring 21 that is highly versatile and has a plurality of standards on the market is used.

In addition to providing such an O-ring 21, a recess groove is provided on one of the outer peripheral surface of the container mounting portion 20 and the inner peripheral surface of the liquid agent container 3 as a detachment preventing portion for the liquid agent container 3, and a convex line is provided on the other. It is good also as a structure which prevents detachment | leave of the liquid agent container 3 by providing this around and this recessed groove and a protruding item | line fitting.
At this time, if at least one of the container mounting portion 20 and the liquid container 3 is formed of an elastic material, the groove and the ridge can be easily attached and detached by elastic deformation.

Contrary to the first embodiment, the container mounting portion 20 may be configured to be held in contact with the mouth of the liquid container 3.
However, when the container mounting portion 20 is configured to circumscribe the liquid container 3, a separation preventing portion made of an elastic material such as rubber is provided around the outer peripheral surface of the mouth of the liquid container 3, so that the container mounting portion 20 and the liquid agent are provided. Since attachment failure with the container 3 is likely to occur, it is preferable that the container attachment portion 20 is configured to circumscribe the liquid agent container 3.

As shown in FIGS. 6 (b) and 7 (b), a liquid agent introduction port 22 for introducing the liquid agent into the diluter main body 2 is provided at the center of the container mounting portion 20.
A straw tube 23 extending downward is attached to the liquid agent inlet 22 so that the liquid agent can be sucked out from the inside of the liquid agent container 3. A plurality of straw tubes 23 having different lengths may be prepared and replaced depending on the depth of the liquid agent container 3, and the straw tube 23 may be formed in an elastic spiral shape to form a large number of one. It may be applicable to the liquid container 3.
A strainer 28 made of a wire mesh is attached to the lower end of the straw tube 23 in order to remove fine dust. The strainer 28 may not be provided if not necessary.

  A structure such as a whistle can be added to the strainer 28 to provide a function to vibrate and emit sound when air is sucked. When such a function is provided, when the liquid in the liquid container 3 is exhausted, air is sucked into the strainer 28 and a sound is generated, so that the user can be notified of the presence or absence of the liquid.

  As shown in FIG. 6, a damping cover 24 is provided around the container mounting portion 20 as a container damping portion that extends downward along the outer peripheral surface of the liquid container 3. The vibration control cover 24 abuts on the outer peripheral surface of the liquid agent container 3 and stops the liquid agent container 3 from shaking in the horizontal direction.

From the liquid agent introduction port 22, a liquid agent flow path 19 that communicates with the upper main flow path 8 extends through a path that does not appear in FIG. 7B.
As shown in FIG. 10B, the upper end of the liquid agent channel 19 is formed so as to join the main channel 8 while reducing the diameter.
A small-diameter portion is provided in the path of the main channel 8, and a large-diameter portion is formed on the downstream side thereof, and the liquid agent channel 19 merges with the main channel 8 at the large-diameter portion.

  In the liquid agent diluting unit 12 that is a confluence portion of the main channel 8 and the liquid agent channel 19, water having an increased flow velocity in the small diameter portion of the main channel 8 generates a negative pressure when passing through the large diameter portion. The liquid agent can be sucked from the liquid agent channel 19 by the negative pressure and diluted with water.

As shown in FIG. 3A, a carrying handle 25 is formed on the upper part of the diluting device main body 2.
The height of the dilution apparatus main body 2 including the handle 25 is preferably 100 to 700 mm.
If it is less than 100 mm, the main flow path 8 becomes too thin and it becomes difficult to provide the liquid agent dilution part 12, and only the small liquid agent container 3 can be used. It is more preferably 150 mm or more, and particularly preferably 200 mm or more.
On the other hand, if it is larger than 700 mm, the diluting device main body 2 becomes large, and it becomes difficult for the user to carry and handle it. More preferably, it is 550 mm or less, and particularly preferably 450 mm or less.
For the above reason, the thickness is set to 365.5 mm in the first embodiment.

The height of the portion excluding the handle 25 of the diluter main body 2 is preferably 60 to 600 mm.
If it is less than 60 mm, the main flow path 8 becomes too thin and it becomes difficult to provide the liquid agent dilution part 12, and only the small liquid agent container 3 can be used. It is more preferably 100 mm or more, and particularly preferably 200 mm or more.
On the other hand, if it is larger than 600 mm, the diluting device main body 2 becomes large and difficult to carry and handle by the user's hand. It is more preferably 500 mm or less, and particularly preferably 400 mm or less.
For the above reason, the thickness is set to 315.5 mm in the first embodiment.

As shown in FIG. 3B, the handle 25 is formed in a U-shaped cross section so that the watering nozzle 5 can be sandwiched in the recessed portion. Thereby, the watering nozzle 5 can be fixed to the handle 25, and the liquid agent diluted watering device 1 can be held and sprayed with the liquid agent diluted like a watering can.
As shown in FIG. 3A, a reinforcing rib 25a is provided on the U-shaped portion of the handle 25 in the vicinity of the base joined to the diluting device main body 2.

The width W1 of the handle 25 is preferably 15 to 100 mm.
If it is less than 15 mm, the handle 25 is too thin and it is difficult for the user to hold it by hand, and the diluting device body 2 may not be supported and may be damaged. It is more preferably 18 mm or more, and particularly preferably 21 mm or more.
If it is larger than 100 mm, the handle 25 is too thick and it is difficult for the user to hold it by hand. 80 mm or less is more preferable, and 50 mm or less is particularly preferable.
For the above reason, the handle width W1 is set to 26 mm in the first embodiment.

The height H1 of the cross section of the handle 25 is preferably 10 to 80 mm.
If it is less than 10 mm, the handle 25 is too thin and it is difficult for the user to hold it by hand, and the diluting device body 2 may not be supported and may be damaged. It is more preferably 12 mm or more, and particularly preferably 15 mm or more.
If it is larger than 80 mm, the handle 25 is too thick and it is difficult for the user to hold it by hand. It is more preferably 60 mm or less, and particularly preferably 40 mm or less.
For the above reason, in the first embodiment, the height H1 of the cross section of the handle 25 is 20 mm.

The wall thickness of the handle 25 is preferably 0.6 to 3.5 mm.
If the thickness is less than 0.6 mm, filling defects during molding are likely to occur, and the product accuracy decreases. Further, since the strength of the handle 35 is reduced, a large number of reinforcing ribs 25a are required, the shape is complicated, the appearance is deteriorated, and the mold cost is increased. It is more preferably 1.5 mm or more, and particularly preferably 2.0 mm or more.
If it is thicker than 3.5 mm, the material cost and molding time increase, and molding defects such as sink marks tend to occur. More preferably, it is 3.2 mm or less, and particularly preferably 3.0 mm or less.
For the above reason, the thickness of the handle 35 is set to 2.5 mm in the first embodiment.

The width W2 of the recessed portion formed in the handle 25 is preferably 12 to 90 mm.
If the thickness is less than 12 mm, the width W1 of the entire handle 25 is inevitably narrowed due to the above-mentioned thickness relationship, and it becomes difficult for the user to hold it by hand, and there is a possibility that the diluting device body 2 cannot be supported and may be damaged.
If it is larger than 90 mm, the width W1 of the entire handle 25 is inevitably increased, and it becomes difficult for the user to hold it by hand. It is more preferably 55 mm or less, and particularly preferably 35 mm or less.
For the above reason, in the first embodiment, the width W2 of the recessed portion is set to 21 mm.

It is preferable that the depth D2 of the recessed part formed in the handle 25 is 7 to 75 mm.
If the thickness is less than 7 mm, the height H1 of the cross section of the handle 25 is inevitably reduced due to the above thickness relationship, and it becomes difficult for the user to hold it by hand, and the diluting device body 2 may not be supported and may be damaged. It is more preferably 10 mm or more, and particularly preferably 12 mm or more.
If it is larger than 75 mm, the height H1 of the cross section of the handle 25 inevitably increases, and it becomes difficult for the user to hold it by hand. It is more preferably 55 mm or less, and particularly preferably 35 mm or less.
For the above reason, the recessed portion is 17.5 mm in the first embodiment.

The handle 25 is not necessarily provided with a recessed portion (see FIGS. 8A and 11A).
In the case where the handle 25 is formed by resin molding, the use of a resin as a material can be reduced by reducing the amount of resin used as a material, the molding time can be shortened, and molding defects such as sink marks can be prevented.

Further, as shown in FIGS. 3A and 10A, an operation knob 26 of the flow path switching valve protrudes from the upper surface of the dilution apparatus main body 2.
In this flow path switching valve, by operating the operation knob 26, the valve body 27 (see FIG. 10A) is moved, and the main flow path 8 that passes through the liquid agent dilution section 12 and the main flow path 8 are branched. Thus, only one of the raw water flow paths (not shown) connecting the water inlet 6 and the water outlet 7 without opening through the liquid agent dilution section 12 is opened.
When water that does not contain a liquid agent is sprayed, the water supplied from the water supply facility can be sprinkled as it is by operating the flow path switching valve to open the raw water flow path.

<Elastic tubes such as hoses>
The hose (not shown) from the water supply facility (not shown) to the water introduction port 6 and the hose 4 from the water outlet 7 to the watering nozzle 5 include a single layer hose made of rubber, a double layer hose, a mesh Any type of hose such as a pressure-resistant hose, a pressure-resistant hose with a coil, or a flexible hose can be used. The hose from the water supply facility to the water inlet 6 and the hose 4 from the water outlet 7 to the watering nozzle 5 may use the same type of hose or different types of hoses. .
