[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an additive liquid mixing device for mixing a predetermined amount of additive liquid with respect to a main liquid, and a sprinkling nozzle that enables the mixing of detergent and the like by applying the device.

[0002]

[Prior art]

 Traditionally, when washing a car at home, the detergent solution is diluted in advance with an appropriate amount of water to make a cleaning solution in a bucket, etc., and the cleaning solution is contained in a sponge, etc., and the sponge scrubs the dirt off. It was

[0003]

[Problems to be solved by the device]

 However, such car washing work has the following problems. It is troublesome to run out of cleaning liquid during car washing, so in the past, it was common to make a sufficient amount of cleaning liquid more than necessary and to discard the excess after cleaning. However, this was not economical and also led to pollution of the river by the discarded detergent. In addition, if the dirt that is attached is terrible, you may want to rub it while covering it with a cleaning solution.However, the cleaning solution filled in a bucket is heavy, and you should sprinkle the dirt with a sponge while applying the cleaning solution while holding the bucket. The work was not easy. Further, since the dirty sponge is pushed into the cleaning liquid stored in the bucket to contain the cleaning liquid, the cleaning liquid itself in the bucket is gradually soiled, and the efficiency of car washing is deteriorated. Because of these problems, there has been a demand for a device that is portable and that can be supplied after diluting a required amount of detergent.

By the way, when washing a car, tap water or the like is guided by a hose in order to wash off dirt and washing liquid. Therefore, if you can mix detergent into the water that comes out of this hose only when you need it, you can carry it and wash the car while spraying the cleaning liquid. To this end, for example, a fluid mixing device described in JP-A-48-59453, JP-B-50-28338, JP-B-54-21582 or the like is applied, and a venturi pipe is provided in the middle of the pipe. A possible method is to suck up the detergent with the negative pressure generated there and mix the detergent into tap water.

However, in these devices, if the flow rate of water does not exceed a predetermined amount, negative pressure is not generated in the venturi tube and the detergent is not mixed (see Japanese Patent Publication No. 54-21582, FIGS. 3 and 4). ). For this reason, when it is desired to wash the car while applying the cleaning liquid little by little, there is a risk that the detergent will not be mixed and only water will come out.

Therefore, an object of the present invention is to provide an additive liquid mixing device capable of mixing an additive liquid even when the flow rate of a main liquid is small, and a sprinkling nozzle capable of mixing detergent etc. by applying the additive liquid mixing device. To do.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the first invention comprises, as described in claim 1, a pipe through which a main liquid flows, a liquid storage tank in which an additive liquid is stored, the liquid storage tank and the pipe. In an additive liquid mixing device that includes a communication pipe for communicating, and mixes a predetermined amount of the additive liquid with respect to the main liquid flowing through the pipe, so that the additive liquid flows into the communication pipe by its own weight, The liquid storage tank is arranged above the pipe, and an added liquid amount adjusting valve capable of adjusting the amount of the added liquid flowing into the communication pipe by an operation from the outside is provided, and the communication pipe is provided with the pipe. It is characterized by a check valve that prevents the main liquid from flowing backward.

In the additive liquid mixing device of the first aspect of the present invention, as described in claim 2, a filter may be further provided downstream of the check valve. Further, in the additive mixture apparatus according to the first aspect of the present invention, as described in claim 3, a filter may be further provided upstream of the check valve.

The check valve may be composed of a valve seat and a ball. Alternatively, the check valve may be composed of a valve seat and a seat-shaped valve body as described in claim 5. As described in claim 6, the liquid storage tank may be made of a transparent material inside.

Further, in the sprinkling nozzle of the second aspect of the present invention, as described in claim 7, the flow rate adjusting valve provided in the flow path is opened / closed by operating a grip handle or the like, so as to be ejected from the ejection port. In a sprinkling nozzle capable of controlling a liquid flow rate, the additive liquid mixing device according to any one of claims 1 to 6 is arranged in a flow path from a downstream side of the flow rate adjusting valve to the ejection port. Characterize.

In the water sprinkling nozzle of the second aspect of the present invention, as described in claim 7, the additional liquid mixing device part having the additional liquid mixing device is sandwiched between a separate shower head part and grip handle part.

[0012]

[Action]

 According to the added liquid mixing device of the first aspect of the present invention, since the liquid storage tank is arranged above the pipe, the added liquid in the liquid storage tank flows into the communication pipe by its own weight. Moreover, when the addition liquid amount adjusting valve is opened and closed, the amount of the addition liquid flowing into the communication pipe is adjusted to a desired mixing amount, and when it is completely closed, the addition liquid is not mixed. In addition, the check valve prevents the main liquid from flowing back from the pipe to the liquid storage tank side and flowing into the liquid storage tank.

In the first aspect of the present invention, when a filter is provided downstream or upstream of the check valve, foreign matter is prevented from being mixed into the main liquid, and the flow rate is controlled by the filtration speed. Further, when the check valve is provided upstream, foreign matter is prevented from being mixed into the check valve, so the durability of the check valve is improved.

In the first aspect of the present invention, when the check valve includes the valve seat and the ball, the durability is good. Further, in the case where the valve seat is composed of the valve seat and the sheet-shaped valve body, since it is lightweight, it quickly rises to the water flow, so that the backflow prevention effect is high. In the first aspect of the invention, when the liquid storage tank is made of a transparent material inside, the remaining amount of the added liquid can be judged from the appearance.

The water sprinkling nozzle of the second aspect of the invention is an application of the additive liquid mixing device of the first aspect of the invention configured as described above, and is extremely useful as a car wash tool. That is, according to the sprinkling nozzle of the second aspect of the present invention, when the grip handle or the like at hand is operated, a desired flow rate of liquid flows through the flow path toward the ejection port. A communication pipe of an added liquid mixing device is connected to this flow path to mix the added liquid. Then, the liquid mixed with the additive liquid is ejected from the ejection port.

Here, since the additive liquid is mixed downstream from the flow rate adjusting valve, there is no concern that the additive liquid will flow back and enter the hose when the flow rate adjusting valve is closed. Further, it is possible to adjust the amount of the added liquid mixed in or to stop the addition of the added liquid by operating the added liquid amount adjusting valve at hand.

Further, in the water sprinkling nozzle of the second aspect of the present invention, when the shower head part and the grip handle part are configured to be directly connectable even if the additive liquid mixing device is removed, the additive liquid mixing device is used when unnecessary. Even if the vessel is removed, it can be used as a watering nozzle, which is extremely convenient.

As a result, the water supplied from the outside is injected into the valve tube 151 from the inside of the joiner 181 through the valve seat 169 as shown by the arrow in FIG. Here, the recess 245 of the grip handle 179 is locked by the grip handle stop projection 243 of the handle stopper 183, and the grip handle 179 is fixed in that state. In this state, the valve shaft 173 is arranged in substantially the same axial direction as the valve seat cylinder 170, and since water pressure is not applied from the side surface, it is not eccentric or vibrated by the water flow, and the valve ball 175 is always kept constant. Can be kept in position. Therefore, the water flow can be kept constant. Moreover, since there is no vibration, the valve shaft 173, the valve ball 175, and the members arranged around the valve shaft 173 are not worn or damaged.

Next, the amount of water is adjusted by the handle cock 141. The amount of water is adjusted by rotating the handle cock 141 and aligning the water mark that is projected on the outer surface 167 of the handle cock 141 with a predetermined position. That is, as shown in FIG. 13, from the state in which the variant opening 159 and the water supply port 153 do not overlap (water is not supplied to the main tube 135), the variant opening 159 provided in the tube cock 139 is handled. By rotating the cock 141, the opening ratio between the water supply port 153 and the irregular opening 159 is changed, and the amount of water discharged to the main tube 135 is adjusted. Then, a desired amount of water is injected into the main tube 135 and further into the selector 43.

Then, by rotating the spray main 5, the spraying state is selected. The selection of the sprinkling state is performed by aligning the selection mark 3 for selecting the sprinkling state printed on the outer periphery thereof with the designation mark 63 of the makeup snap ring 53. That is, as shown in FIGS. 2, 4 and 14, when the fan-shaped ejection mark 3a of the selection mark 3 is aligned with the designated mark 63, the injection opening 121 of the selector 43 is the first supply opening of the distributor 19. As shown in FIG. 14, water exits the injection opening 121 from inside the selector 43 and is ejected from the first supply opening 73 to the fan-shaped ejection opening 91 that communicates with the first supply opening 73. To be done. Here, the linear ejection port 89 is closed by the lid portion 99 of the needle 23 to prevent dust and the like from entering.

Furthermore, when the shower-like jetting mark 3b of the selection mark 3 is aligned with the designated mark 63 by rotating the spray main 5, as shown in FIG. By advancing to the left, the communication between the injection opening 12 1 and the first supply opening 73 as described above is closed, and the injection opening 121 of the selector 43 is connected to the second supply opening 77 of the distributor 19. It Then, the water exits the injection opening 121 from inside the selector 43 as shown by the arrow in FIG. 15, and is ejected from the second supply opening 77 to the shower-like ejection port 111 communicating with the second supply opening 77.

Furthermore, when the spray-shaped main body 5 is rotated to align the jaw-like jetting mark 3c of the selection mark 3 with the designated mark 63, the selector 43 as shown in FIG. Further, it is advanced to the left, the communication between the injection opening 121 and the second supply opening 77 as described above is closed, and the selector 43 pushes the needle 23. Then, the injection opening 121 of the selector 43 opens in the needle chamber 82, and the water exits the injection opening 121 from inside the selector 43 and is ejected from the needle chamber 82 to the linear ejection port 89. The coil spring 25 imparts a rotational force along the spiral direction of the water, and the water is beautifully discharged straight and along the axis of the needle 23. In this state, the injection opening 121 of the selector 43 has a small opening ratio in the needle chamber 82, so the amount of water is small, and the water is jetted in a scaly shape. Here, for the first time, the linear jet port 89 communicates with the inside of the distributor 19, but since water pressure is constantly applied, dust and the like will not enter from the outside.

Furthermore, when the linear ejection mark 3d of the selection mark 3 is aligned with the designated mark 63 by rotating the spray main 5, as shown in FIG. It moves forward to the left and pushes the needle 23 further than the above. Then, the water exits the injection opening 121 from the inside of the selector 43 and is ejected from the needle chamber 82 to the linear ejection port 89 in the same manner as described above, but the injection opening 121 of the selector 43 is sufficiently in the needle chamber 82. Since it is opened, the amount of water is sufficient and water is ejected in a straight line.

Further, when the atomized jet mark 3e of the selection mark 3 is aligned with the designation mark 63 by rotating the spray main 5, as shown in FIG. Further, it is advanced to the left, and the needle 23 is pushed in more than the above. Then, in the same manner as above, water exits the injection opening 121 from the selector 43 and is ejected from the needle chamber 82 to the linear ejection port 89, but the protruding portion 101 of the needle 23 ejects the linear ejection port 89. Since the gap between the protruding portion 101 of the needle 23 and the straight-line ejection port 89 that penetrates is extremely narrow, water collides with the umbrella-shaped portion 105 along the protruding portion 101 of the needle 23. It is ejected in the form of a mist as an umbrella-shaped thin film.

When the use is finished, the inflow of water is stopped as follows. That is, the grip handle 179 is gripped again. Then, since a clearance is generated between the grip handle stop projection 243 of the handle stopper 183 and the recess 245 of the grip handle 179, the handle stopper 183 is urged clockwise by the urging plate 241, and this locking is released. Get burned. Then, the gripping force of the grip handle 179 is released. Then, the pressing down of the valve ball 175 by the valve shaft 173 is released, so that the valve spring 177 urges the valve ball 175 upward, and the valve seat 169 is closed in a watertight manner. At the same time, the valve spring 177 pushes up the valve ball 175, thereby pushing up the valve shaft 173 (X2 direction in FIG. 10) and urging the valve lever 205 in the counterclockwise direction (X1 direction in FIG. 10). Since the return spring 220 biases the valve lever 205 in the counterclockwise direction, the valve lever 205 presses the grip handle 179, and the grip handle 179 swings in the counterclockwise direction, returning to the state shown in FIG. . Here, in order to further increase the counterclockwise biasing force of the grip handle 179, a biasing member may be provided on the spring receiver 251 (FIG. 5) between the grip handle 179 and the grip housing 51.

It is preferable that the amount of water and the sprinkling state are selected before the water is supplied, because the desired state can be obtained at the same time as the water is supplied. Then, fine adjustment may be made from there. Next, the additive liquid mixing device part, which is a characteristic part of this embodiment, will be described.

FIG. 19 is a partial cross-sectional view showing the vicinity of the additive liquid mixing device section 1C in a broken manner, and a part of the grip assembly section 1A is omitted. 20 is a cross-sectional view showing only the additive liquid mixing unit 1C with the grip assembly 1A and the shower head assembly 1B removed.

As shown in FIGS. 19 and 20, the additive liquid mixing unit 1 C is a connecting cylinder 261 which is fitted to the spray main 5 on the left end side in the drawing and is fitted to the grip housing 51 on the right end side in the drawing. A water flow tube 263 fixed to the axis of the water tube 261, a communication tube 265 integrally formed on the upper side of the water flow tube 263 in the figure, and a drug container that is arranged on the upper side of the connection tube 261 in the figure and screwed into the communication tube 265. 267, a lid 269 screwed onto the outer periphery of the drug container 267 to close the upper opening thereof, a drug valve shaft 270 supported by the lid 269 so as to be able to move up and down, and a lid 269 rotatably fitted. It is provided with a medicine valve drive plug 271 which is combined and rotates the medicine valve shaft 270 up and down.

The left end side of the connecting cylinder 261 has the same shape as the left end side of the grip housing 51, and the spray main 5 is rotatably connected by the makeup retaining ring 53. Further, the right end side of the connecting cylinder 261 has substantially the same shape as the right end side of the spray main 5, and the cosmetic housing retaining ring 53 connects the grip housing 51. However, the concave portion 272 with which the makeup snap ring 53 is caught does not extend in the circumferential direction like the groove 57 of the spray main 5, and the connecting cylinder 261 is fixed to the grip housing 51 so as not to rotate.

The running water cylinder 263 has a shape similar to the main tube 135 of the grip assembly portion 1A on the left side in the figure, and is fitted with an O-ring 273 on the outer periphery so as to be slidably fitted in the selector 43 in a watertight manner. There is. A main tube 135 is watertightly fitted on the right side of the running water cylinder 263 in the figure. Further, a guide plate 275 is attached to the side surface of the running water cylinder 263, and guides the selector 43 in the sliding direction, like the guide plate 115 attached to the main tube 135.

An O-ring 276 is attached to the outer periphery of the communication cylinder 265, and a cylindrical portion 277 at the lower end of the drug container 267 is watertightly screwed. Further, a filter 279 is arranged inside the communication tube 265. In the embodiment, the filter 279 is made by bundling ultrafine nylon fibers and compression-molded, and has a feeling just like a cigarette filter.

The medicine container 267 is composed of a tank portion 280 filled with a drug solution and a cylindrical portion 277 communicating with the tank portion 280. Inside the cylindrical portion 277, a check valve seat made of an elastic material such as rubber is provided. 281 and a check valve ball 282 made of metal. The check valve seat 281 is supported and fixed by the ball pressing member 283, and the check valve ball 282 is enclosed in the ball pressing member 283 with play. Since the check valve ball 282 is spherical, it has excellent durability.

The lid body 269 is integrally formed with a two-stage cylinder 285 extending downward from substantially the center. The upper and lower sides of the two-stage cylinder 285 are open, and the drug valve shaft 270 is inserted from the upper side. The drug valve shaft 270 is screwed into the drug valve drive plug 271 at the screwing portion 287 at the upper end, and by rotating the drug valve drive plug 271, the drug valve shaft 270 moves up and down. A flange 289 is formed on the medicine valve shaft 270. The collar portion 289 has a valve spring 291 sandwiched between it and the stepped portion of the two-stage cylinder 285. Therefore, when the drug valve shaft 270 is lowered, the valve spring 291 is compressed, and an upward biasing force acts on the drug valve shaft 270. Further, the flange portion 289 is formed with a protrusion 293 that further protrudes laterally. The protrusion 293 is inserted into the rotation stop groove 295 extending in the vertical direction along the two-stage cylinder 285. As a result, the movement of the medicine valve shaft 270 is restricted so as not to rotate together with the medicine valve drive plug 271 and is guided in the up-down direction. Further, the lower end of the medicine valve shaft 270 is covered with a medicine valve 297 made of an elastic material such as rubber. The medicine valve 297 watertightly closes the communication hole 299 to the cylindrical portion 277 when the medicine valve shaft 270 is lowered. The drug valve drive stopper 271 is rotatably fitted in the flange 301 on the upper portion of the lid 269. In addition, a small air hole 303 is formed at a substantially central portion of the drug valve drive plug 271. From this air hole 303, air is introduced into the medicine container 267 through a communication passage (not shown).

Next, the function of each part of the additive liquid mixing unit 1C will be described by taking as an example the case where the detergent is diluted with water and discharged. First, the medicine container 267 is filled with a household neutral detergent or the like. The detergent flows from the tank portion 280 through the communication hole 299 into the tubular portion 277 by its own weight. At this time, the check valve ball 282 is positioned below by its own weight, and the detergent reaches the filter 279 through the gap around the check valve ball 282. In the filter 279, the foreign matter is filtered and only the detergent exudes into the running water cylinder 263.

Next, as described in detail above, the grip handle 179 is operated to cause water to flow into the main tube 135. The water flowing into the main tube 135 flows into the running water cylinder 263. When the water flows into the running water cylinder 263, the cleaning agent impregnated in the filter 279 is drawn into the water flow or melts into the water flow to be mixed into the water. At this time, the detergent oozes out little by little by the filter 279, so that the detergent does not flow out all at once. The water thus mixed with the detergent is guided from the running water cylinder 263 to the selector 43. As described in detail above, the water that has flowed into the selector 43 is discharged into a fan shape, a shower shape, a scallop shape, a linear shape, or a mist shape through the flow path according to the rotation position of the spray main 5. .

Here, the mixing amount of the detergent is adjusted to a basic amount by the chemical valve drive plug 271. That is, when the medicine valve drive plug 271 is rotated, the medicine valve shaft 270 is moved up and down to increase or decrease the width of the gap between the medicine valve shaft 270 and the communication hole 299, and the amount of the detergent flowing into the communication hole 299 is adjusted. Particularly, when the medicine valve shaft 270 is lowered to the lowest position, the medicine valve 297 closes the communication hole 299 in a watertight manner, and the mixing of the detergent is stopped. Therefore, for example, when washing a car, first, the detergent is mixed in to wash off the dirt, and then the mixing of the detergent is stopped and the detergent portion is washed away with water. You can easily do it.

Further, the amount of detergent mixed in is automatically increased or decreased with respect to the basic amount described above according to the flow rate of water flowing in the water flow tube 263. That is, when the flow rate is high, the amount of detergent drawn by the water flow is high. On the other hand, even when the flow rate is low, the detergent will be dripped little by little due to the weight of the detergent, and the detergent will dissolve into the running water. Therefore, the detergent is mixed regardless of the flow rate of water, and in particular, it is possible to wash the car while flowing a small amount of the washing liquid.

Further, when the spray main 5 is rotated in the sprinkling state to switch the sprinkling form, the water channel is closed in the shower head assembly section 1B, and the water pressure in the water pipe 263 is suddenly increased. May rise to. At this time, the running water tries to flow into the medicine container 267, but the flow causes the check valve ball 282 to be lifted up and come into close contact with the check valve seat 281. Therefore, water does not spray into the medicine container 267.

In addition, when the watering is stopped, as described in detail above, when the grip handle 179 is gripped again, the valve ball 175 watertightly closes the valve seat 169 (see FIG. 13), and the main tube 135. The water that had flowed in stopped. At this time, a small amount of the cleaning liquid remains in the downstream portion from the running water cylinder 263, but the valve ball 175 and the valve seat 169 block the reverse flow upstream thereof, so that the detergent such as the water pipe, which is the water supply source, is not cleaned. There is no worry about infiltration. The cleaning liquid remaining in the downstream portion from the running water cylinder 263 also leaks from the spray sheet 27 side when air enters from the spray sheet 27 side. Further, if the medicine valve driving plug 271 is operated to block the communication hole 299 with the medicine valve 297, the detergent cannot be completely leaked.

As described above, according to the present embodiment, it is possible to mix the tap water guided by the hose with the detergent as needed and spray the water. Therefore, it is also possible to carry the car while carrying the cleaning liquid and washing the car. In particular, even when it is desired to wash the car while applying the cleaning liquid little by little, it is possible to discharge the water mixed with the detergent. As a result, it is possible to always supply a clean cleaning solution as much as necessary, which is economical and easy for car washing.

Further, it is possible to easily adjust the amount of the detergent mixed in by hand. In particular, since it is possible to stop mixing and release only water, a series of car wash operations such as detergent washing and water washing can be performed smoothly. Further, in the embodiment, even if the additive liquid mixing unit 1C is removed, it can be assembled as a water spray nozzle. Therefore, in manufacturing both a water spray nozzle with a chemical container and a normal water spray nozzle, the sharing ratio of parts is reduced. 100%, leading to cost reduction.

Next, a second embodiment will be described. FIG. 21 is a front view showing a water spray nozzle 1 as a second embodiment, in which an additive liquid mixing unit 1C is improved. As shown in FIG. 22 (a), in the additive liquid mixing device 1C according to the present embodiment, a mixing amount mark 311 is displayed on the upper surface of the drug valve driving plug 271 so that the rotation operating direction of the drug valve driving plug 271 can be visually recognized. I understand it. Further, as shown in FIG. 22B, a reinforcing plate 313 is formed on the outer periphery of the cylindrical portion 277 at the lower end of the medicine container 267 to increase the strength of the constricted portion. The medicine container 267 is made of a transparent polyethylene terephthalate resin (PET), and the amount of the cleaning agent contained therein can be seen at a glance. Therefore, it is possible to prevent the medicine from being used in the absence of the medicine and to easily confirm the flow rate of the medicine.

Further, as shown in FIG. 23, the structure near the medicine valve shaft 270 is changed. Unlike the previous embodiment, the drug valve shaft 270 rotates integrally with the drug valve drive plug 271 and is slidably fitted in the drug valve drive plug 271 in the vertical direction. Further, the medicine valve shaft 270 is screwed into a cylindrical portion 315 formed integrally with the lid body 269. Therefore, in the present embodiment, when the medicine valve drive plug 271 is rotated, the medicine valve shaft 270 also rotates and is guided by the thread groove of the cylindrical portion 315, and the medicine valve shaft 270 moves up and down.

Next, a third embodiment will be described. FIG. 24 is a cross-sectional view of the additive liquid mixture unit 1C as the third embodiment. In the additive mixture unit 1C in this embodiment, a valve shaft 321 is provided in place of the drug valve shaft 270 and the drug valve drive plug 271 in the previous two embodiments. The valve shaft 321 is rotatably supported by the lid 269, and the lower end portion is fitted into the notched cylinder portion 323 formed inside the medicine container 267, and the upper end portion can be operated to rotate. A drug channel 325 is formed at the lower end of the valve shaft 321. When the valve shaft 321 is rotated, a deformed opening 325a on the end face of the drug channel 325 is exposed at the notched portion of the notched tubular portion 323, and The portion 280 and the tubular portion 277 communicate with each other. As shown in FIG. 25A, when the valve shaft 321 is rotated all the way to the right, the odd-shaped opening 325a of the drug channel 325 is completely exposed and the opening ratio becomes 100%. As shown in Fig. 7, when it is rotated to the left, the aperture ratio becomes gradually smaller, and when it is rotated all the way to the left, it is completely hidden by the notched tubular portion 323 and the aperture ratio is 0%. become. Therefore, by rotating the valve shaft 321, the inflow amount of the detergent can be finely adjusted continuously, and the inflow can be completely stopped.

Further, in this embodiment, the filter 279 is made of a felt having a coarser texture than that of the above-mentioned embodiments. Therefore, the detergent is more likely to ooze out from the filter 279, but if the amount of oozing out is finely adjusted by the valve shaft 321, the detergent will not flow out all at once. Furthermore, if the opening ratio of the valve shaft 321 is adjusted to be small and the amount is appropriately dropped, it is possible to mix an appropriate amount of detergent even if the filter 279 is removed.

Further, in the present embodiment, the valve seat 331 made of an elastic material such as rubber is provided inside the tubular portion 277. This valve seat 331 replaces the check valve ball 282 in the previous embodiment, and is lifted when running water is about to flow from the filter 279 side into the medicine container 267, and water is injected into the medicine container 267. To prevent Since the valve seat 331 is extremely thin (thickness 0.6 mm in the embodiment) and lightweight, it immediately lifts when receiving a water flow from the filter 279 side, and the backflow prevention effect is particularly high.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modes can be adopted without departing from the scope of the present invention. For example, the filter 279 may be made of any material that allows the liquid to soak into it, and in addition to synthetic fibers such as nylon fibers, natural fibers such as cotton and hemp, glass fibers, and the like may be used. In particular, a fiber obtained by bundling such fibers in the same direction and compression-molding the fibers is particularly desirable because the liquid easily penetrates. Further, the filter may be formed of synthetic resin foam including open cells such as polyurethane.

Further, in each of the above embodiments, the filter 279 is provided on the check valve, that is, on the downstream side of the check valve seat 281 and the check valve ball 282 or the valve seat 331. It may be provided upstream of the valve. In this case, foreign matter is prevented from being mixed into the check valve, so the durability of the check valve is improved.

[Effect of device]

 As described above, according to the present invention, the liquid storage tank is arranged above the pipe so that the added liquid drips by its own weight. Therefore, even if the flow rate of the main liquid is small, The additive liquid can be mixed with the main liquid.

Further, since the additive liquid is guided downward from the liquid storage tank, the additive liquid is not wasted in the tank and is not wasted. Further, by providing the added liquid amount adjusting valve, the mixed amount of the added liquid can be adjusted to a desired amount simply by opening and closing the added liquid amount adjusting valve. In particular, if it is completely closed, the additive liquid will not be mixed in at all.

Further, the check valve prevents the main liquid from flowing back from the pipe to the liquid storage tank side and flowing into the liquid storage tank. Therefore, it became possible to properly mix only the desired amount of the additive liquid, regardless of the amount of the main liquid.

Furthermore, when a filter is provided downstream or upstream of the check valve, foreign matter is prevented from being mixed into the main liquid, and the flow rate is controlled by the filtration speed, so that the flow rate of the additive liquid can be increased. The control effect is high. Further, when the check valve is provided upstream, foreign matter is prevented from being mixed into the check valve, so that the durability of the added liquid amount adjusting valve is improved.

When the check valve is composed of the valve seat and the ball, the durability is good, and when the valve seat is composed of the valve seat and the sheet-shaped valve body, the check valve is light in weight and therefore resistant to water flow. Since it starts up quickly, it has a high backflow prevention effect. When the liquid storage tank is composed of a transparent material inside, it is possible to judge the remaining amount of the added liquid from the outside, so it is possible to prevent the use of the liquid without the added liquid, and The flow rate of the liquid can be easily confirmed.

Furthermore, according to the sprinkling nozzle of the second aspect of the present invention, it is possible to discharge a required amount of cleaning liquid easily without wasting detergent, and it is easy to handle, which is extremely useful as a car wash tool. In particular, the additive liquid such as detergent is mixed downstream from the flow control valve of the water spray nozzle, so there is no concern that the additive liquid will flow back and enter the hose or water pipe when the flow control valve is closed. In addition, it is possible to switch between mixing and stopping the detergent by hand operation, so a series of car washing operations such as cleaning the detergent with detergent and then rinsing off the detergent can be performed extremely smoothly.

In addition, according to the water spray nozzle of the third aspect of the present invention, it can be used as a water spray nozzle even when the additive liquid mixing device is removed when unnecessary, which is extremely convenient.
