Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a drug dilution apparatus,

The present invention relates to a so-called drug dilution having an ejector jet pump structure in which a drug such as liquid fertilizer is sucked by generating a negative pressure, diluted with water supplied from a water supply equipment, Water spraying apparatus.

In the fields of gardening and agriculture, liquid fertilizer, pesticide and other medicines are diluted and sprayed to water supplied from water supply equipment such as water.

Further, when cars are washed at home, it has been practiced to dilute the washing detergent with water to spray.

In order to widely dilute a drug other than water in water, a drug dilution sprinkler has been conventionally used.

The chemical dilution water spraying apparatus of Patent Document 1 has a connection port for introducing water from a water supply facility through a hose or the like and a water spray port for discharging the water and has a main flow path through which water flows from the water introduction port to the water spray port And is formed as a water spray nozzle provided.

This drug dilution water spraying apparatus is detachably attached to a lower portion of the medicine container containing the medicine by screwing. The inside of the medicine container is communicated with a medicine dilution part which is a merging part with the main flow path by a medicine flow path made of a hose or a tube.

In the medicament diluted part, since the diameter of the main flow path is reduced on the upstream side and the diameter is enlarged on the downstream side, a negative pressure is generated at the time of water passage and the medicine is sucked from the medicine container It was possible to dilute.

However, in the chemical dilution spray apparatus of Patent Document 1, since the medicine container is directly attached to the lower part of the spray nozzle, the spray nozzle becomes heavy and it is difficult to handle with one hand. In addition, since the medicine container is integrally mounted on the spray nozzle, the device becomes large and difficult to handle, and it is difficult to live in a narrow range such as a flowerpot plant.

In addition, since the spray nozzle and the medicine container are fixed by screwing the female screw formed on the spray nozzle and the male screw formed on the medicine container, the thread engagement is loosened due to vibration during use, .

Further, since the load is always concentrated on the threaded portion which is the fixed portion of the spray nozzle and the medicine container, there is a fear that the joint portion is broken by the stress or the momentary impact over time.

Patent Document 2 discloses a technique in which a medicine container is held by a user on his or her shoulder and a medicine is supplied by the hose from the medicine container to the base end portion of the spray nozzle, Discloses a chemical dilution spraying apparatus that dilutes an agent into water to dilute it.

The structure of the drug diluting part for diluting the drug with water is almost the same as that of the patent document 1. [

However, in the chemical dilution spray apparatus of Patent Document 2, since there are two lines of hoses, that is, a hose for supplying water to the spray nozzle from the water supply equipment and a hose for supplying the medicine to the spray nozzle from the medicine container, And the like.

Further, when the hose connecting the medicine container to the spray nozzle is folded or twisted during use, the suction amount of the medicine is reduced, and a predetermined dilution concentration can not be achieved. If a rigid hose is used to prevent this, there is a problem that the handling of the user is further deteriorated.

Since the drug container and drug dilution part are located far away from each other through the hose, there is a problem that the negative pressure necessary to draw the medicine becomes large, and that it takes time until the medicine is diluted through the hose after starting watering at the spray nozzle .

Further, since the medicament diluted portion is formed at the base end portion of the spray nozzle, the sprinkler nozzle becomes bulky and heavy, which makes handling difficult.

In addition, since the drug dilution part is embedded in the spray nozzle, drug dilution spraying can not be performed in a device other than the sprinkling nozzle such as a sprinkler.

[

<Body of diluting device>

Hereinafter, the dilutation apparatus main body 2 will be described in detail.

As shown in Figs. 3 and 10, the diluting device main body 2 has a main flow passage 8 for passing water through the upper portion thereof, and also houses the chemical container 3 in its lower portion, The medicament is diluted with water and sent to the spray nozzle 5. [

As shown in Figs. 3 and 4, a hose 4 or the like (not shown) is connected to an upper portion of one side surface of the dilutation apparatus main body 2 to supply water from an upstream water supply facility A hose nipple 13 provided with a water inlet 6 for introducing water is protruded.

A hose connector 14 is formed at the upper part of the opposite side of the dilution device body 2, with a water outlet 7 for leading water out.

The water inlet 6 and the water outlet 7 are connected to the main channel 8 passing through the diluter main body 2 from right to left in Figures 4 (c) and 10 (a) .

The lower medicament container storage portion is formed with a space (medicament container storage portion) for housing the medicament container 3 therein, and the front portion of the medicament container 3 is cut out for insertion and removal of the medicament container 3 And is formed as a housing body provided with an opening in the upper half of the back surface portion.

The left and right side portions and the back surface portion of the medicine container housing portion have a function of covering the medicine container 3 to be stored and protecting it from an impact or the like.

The medicine container 3 need not be entirely housed in the drug container housing portion but may be exposed or protruded from the drug container housing portion.

In addition, below the medicament container storage portion, a base 15 extending beyond the medicament container storage portion is formed to prevent the dilutation device main body 2 from turning.

As shown in Fig. 3 (a), the center of the base 15 is cut out in a circular shape so as to prevent water and dust from accumulating.

The width of the base block 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 drug dilution part 12. More preferably 100 mm or more, and particularly preferably 120 mm or more.

If it is larger than 400 mm, the dilutation device main body 2 becomes large and it becomes difficult to carry and handle by the user's hand. More preferably 350 mm or less, and particularly preferably 300 mm or less.

For the above reason, in the first embodiment, the left and right widths of the foundation rests 15 are 180 mm.

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, which makes it difficult to provide the drug dilution part 12, and it becomes impossible to use only the small medicine container 3. More preferably 80 mm or more, and particularly preferably 100 mm or more.

If it is larger than 400 mm, the dilutation device main body 2 becomes large and it becomes difficult to carry and handle by the user's hand. More preferably 300 mm or less, and particularly preferably 250 mm or less.

For the above reason, in the first embodiment, the width of the base 15 is 118 mm.

As shown in Figs. 3 and 6, the dilutation apparatus main body 2 can be divided into two parts, that is, the upper member 16 and the lower member 17 at the height of the medicine container housing part.

The upper member 16 and the lower member 17 are integrally fixed by the lever fixing hole 18 and can be disassembled by removing the lever fixing hole 18. [ When the medicine container 3 is mounted on the diluter main body 2, the medicine container 3 is disassembled into the upper member 16 and the lower member 17 and then inserted into the lever fixing hole 18 Thereby assembling the diluter main body 2 integrally.

As the material of the dilutation apparatus main body 2, plastic, metal, and glass can be used.

Of these, plastics or metals such as stainless steel, brass, zinc and aluminum are preferable because they are lightweight, suitable for transportation, less deteriorated in rust, less likely to be broken, and easy to be processed. In addition, plastic is particularly preferable because the raw material and production cost are inexpensive.

In the first embodiment, plastic is used for the above reasons.

In addition, when it is intended to cause rust, corrosion, or chemical stress cracks as the medicament, it is preferable that the components of the main channel 8, the medicament channel 19 (see Fig. 10) It is preferable to use this excellent material.

6, a container mounting portion 20 for connecting the medicine container 3 is formed in the diluter main body 2 above the medicine container storage portion.

As shown in Fig. 6 (b), the container mounting portion 20 is formed to have a diameter dimension capable of being held in contact with the entrance of the tip end of the medicine container 3 by friction force.

7 (b), even if a ring-shaped O-ring 21 made of an elastic material is provided along the circumference of the container mounting portion 20 as a release preventing portion of the medicine container 3 good.

When the distal end of the chemical container 3 is inserted into the container mounting portion 20, the O-ring 21 is elastically deformed to come into contact with the inner peripheral surface of the chemical container 3 and the elastic force and friction force of the O- (3), so that it is possible to prevent departure.

The O-ring 21 serving as the departure-avoiding portion is provided so that the chemical container 3 is firmly attached to the container mounting portion 20 even if the outer peripheral surface of the container mounting portion 20 or the inner peripheral surface of the chemical container 3 is not so high in dimensional accuracy. .

The diameter (outer diameter) of the O-ring 21 is preferably 5 to 80 mm.

When the diameter is set to less than 5 mm, the inlet diameter of the medicine inlet 22 or the straw tube 23, which will be described later, must be set small, and the medicine can not be sucked sufficiently.

If the diameter is set to be larger than 80 mm, the inlet of the drug container 3 or the dilutation device main body 2 becomes large, and the drug container 3 becomes difficult to be detached and handled.

The diameter is more preferably 10 to 50 mm, and the diameter is more preferably 17 to 22 mm. For the above reasons, in the first embodiment, an O-ring 21 having a diameter of 19 mm was used.

As the material of the O-ring 21, rubber or elastomer can be used.

Since it is preferable to prepare plural kinds of standards different in capacity and shape from each other in the medicine container 3 to be mounted on the dilutation device main body 2, . For this reason, in this embodiment, an O-ring 21 made of rubber, which has high versatility and has a plurality of specifications on the market, is used.

In addition to providing such an O-ring 21, as a release preventing portion of the medicine container 3, a concave groove is formed along the circumference of the outer circumferential surface of the container mounting portion 20 and the inner circumferential surface of the medicine container 3 A convex band may be formed on the other side along the circumference and the concave groove and the convex band may be fitted to each other to prevent the medicine container 3 from being separated.

At this time, if at least one of the container mounting portion 20 and the medicine container 3 is made of an elastic material, the elastic deformation can facilitate the detachment of the concave groove and the convex band.

In addition, contrary to the first embodiment, the container mounting portion 20 may be configured so as to be held circumscribed (circumscribed) with respect to the entrance of the medicine container 3.

If the container mounting portion 20 is constructed so as to be in contact with the medicine container 3, a separation preventing portion made of an elastic material such as rubber is formed around the outer peripheral surface of the entrance of the medicine container 3, It is preferable that the container mounting portion 20 be in contact with the medicine container 3 because the mounting failure of the mounting portion 20 and the medicine container 3 tends to occur easily.

6 (b) and 7 (b), a medicament introducing port 22 for introducing medicines into the diluter main body 2 is provided at the center of the container mounting portion 20 .

The drug introducing port 22 is provided with a straw tube 23 extending downward so that the medicine can be drawn from the inside of the drug container 3. The straw tube 23 may be provided with a plurality of straw tubes 23 having different lengths and may be replaced in correspondence to the depth of the medicine container 3 or may be formed in a spiral shape having elasticity, It may be applicable to the medicine container 3.

At the lower end of the straw tube 23, a strainer 28 made of a wire mesh is attached to remove fine dust. The strainer 28 may not be provided if it is not necessary.

A structure such as a flute may be added to the strainer 28 to have a function of vibrating and making a sound when air is sucked. When such a function is provided, air is sucked into the strainer 28 when the medicine in the medicine container 3 is exhausted, so that the user can be informed of the presence or absence of the medicine.

6, a vibration suppression cover 24 as a container vibration suppressing section extending downward along the outer circumferential surface of the medicine container 3 is provided around the container mounting section 20. As shown in Fig. The vibration suppression cover 24 contacts the outer circumferential surface of the medicine container 3 to prevent the medicine container 3 from shaking in the horizontal direction.

A drug channel 19 communicating with the upper main channel 8 is extended from the drug inlet 22 by a route not shown in Fig. 7 (b).

As shown in Fig. 10 (b), the upper end of the medicine flow path 19 is formed so as to join the main flow path 8 with a reduced diameter.

A large diameter portion is formed on the downstream side of the main flow path 8 and a large diameter portion is formed on the downstream side of the main flow path 8. In the large diameter portion, ).

The chemical dilution part 12 which is the merging part of the main flow path 8 and the chemical flow path 19 generates a negative pressure when water having a flow rate increased in the small diameter part of the main flow path 8 passes through the large diameter part , The medicine can be sucked from the medicine channel (19) by this negative pressure and diluted with water.

As shown in Fig. 3 (a), a hand grip 25 for carrying is formed in the upper part of the diluter main body 2. As shown in Fig.

The height of the dilutation apparatus main body 2 including the handle 25 is preferably 100 to 700 mm.

If the length is less than 100 mm, the main flow path 8 becomes too thin, which makes it difficult to provide the drug dilution part 12, and it becomes impossible to use only the small medicine container 3. 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 dilutation device main body 2 becomes large and it becomes difficult to carry or handle by the hand of the user. More preferably 550 mm or less, and particularly preferably 450 mm or less.

For the above reason, in the first embodiment, it is set to 365.5 mm.

The height of the portion of the dilutation apparatus main body 2 excluding the handle 25 is preferably 60 to 600 mm.

If it is less than 60 mm, the main flow path 8 becomes too thin, which makes it difficult to provide the drug dilution part 12, and it becomes impossible to use only the small medicine container 3. More preferably 100 mm or more, and particularly preferably 200 mm or more.

If it is larger than 600 mm, the dilutation apparatus main body 2 becomes larger and it becomes difficult to carry or handle by the hand of the user. More preferably 500 mm or less, and particularly preferably 400 mm or less.

For the above reason, in the first embodiment, it was set to 315.5 mm.

Thereby, the spray nozzle 5 can be fixed to the handle 25, the entire drug dilution spraying apparatus 1 can be held, and a diluted drug such as a sprinkler can be sprayed.

As shown in Fig. 3 (a), a reinforcing rib 25a is provided in the U-shaped portion near the bottom of the knob 25 which is joined to the dilutation apparatus main body 2.

The width W1 of the handle 25 is preferably 15 to 100 mm.

If the length is less than 15 mm, the handle 25 is too thin, which makes it difficult for the user to grip the hand, and the diluter main body 2 can not be supported and may be damaged. 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, which makes it difficult for the user to grip the handle 25. More preferably 80 mm or less, and particularly preferably 50 mm or less.

For the above reason, in the first embodiment, the width W1 of the handle is set to 26 mm.

The height H1 of the cross section of the handle 25 is preferably 10 to 80 mm.

If the length is less than 10 mm, the handle 25 is too thin, which makes it hard for the user to hold the hand, and the diluter main body 2 can not be supported and may be damaged. 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, which makes it difficult for the user to grasp the handle 25 by hand. 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 end face of the handle 25 is 20 mm.

The thickness of the handle 25 is preferably 0.6 to 3.5 mm.

When the thickness is less than 0.6 mm, charging failure at the time of molding tends to occur, resulting in lower product precision. Further, since the strength of the knob 35 is lowered, a large number of reinforcing ribs 25a are required, resulting in complicated shapes, deteriorated appearance, and increased mold cost. More preferably 1.5 mm or more, and particularly preferably 2.0 mm or more.

If the thickness is more than 3.5 mm, material cost and molding time are increased, and defective molding such as a sink mark is likely to occur. More preferably 3.2 mm or less, and particularly preferably 3.0 mm or less.

For the above reason, in the first embodiment, the thickness of the handle 35 is 2.5 mm.

The width W2 of the concave 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 knob 25 as a whole is inevitably narrowed due to the above thickness, so that it is difficult for the user to hold it by hand, and the diluter main body 2 can not be supported, have.

If it is larger than 90 mm, the width W1 of the entire knob 25 becomes necessarily larger, which makes it difficult for the user to hold the knob 25 by hand. More preferably not more than 55 mm, and particularly preferably not more than 35 mm.

For the above reason, in the first embodiment, the width W2 of the concave portion is set to 21 mm.

The depth D2 of the concave portion formed in the handle 25 is preferably 7 to 75 mm.

7 mm, the height H1 of the cross section of the knob 25 is inevitably reduced due to the relationship of the thickness, so that it is difficult for the user to hold it by hand, and the diluter main body 2 can not be supported, have. More preferably 10 mm or more, and particularly preferably 12 mm or more.

75 mm, the height H1 of the end face of the knob 25 is inevitably increased, which makes it difficult for the user to grip the knob 25 by hand. More preferably not more than 55 mm, and particularly preferably not more than 35 mm.

For the above reason, in the first embodiment, the concave portion is set to 17.5 mm.

The handle 25 may not necessarily be provided with a concave portion (see Figs. 8 (a) and 11 (a)).

When the knob 25 is formed by resin molding, provision of the recessed portion reduces the amount of resin used as the material, shortens the molding time, and prevents defective molding such as sink marks and the like.

3 (a) and Fig. 10 (a), the operation switch 26 of the flow path switching valve projects from the upper surface of the dilutation apparatus main body 2. As shown in Fig.

In this flow path switching valve, by operating the operation switch 26, the valve body 27 (see Fig. 10A) is moved to move the main flow path 8 A raw water flow path (not shown) for branching from the main flow path 8 and connecting the water introduction port 6 and the water outlet port 7 without passing through the drug dilution part 12 .

In the case of spraying water not containing a medicament, by opening the raw water flow path by operating the switching valve, the water supplied from the water supply equipment can be sprinkled.
