Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a double-headed nozzle for an atomizer.

[Prior Art] Conventionally, sprayer nozzles have been made so that the spray form (range or spread) can be changed, for example, a single-head nozzle type and a double-head type nozzle, which can be exchanged. is proposed.

[Problems with the prior art] However, such conventional nozzles require two types of nozzles: a single-headed type and a double-headed type, which makes them expensive and uneconomical, and the spraying process is difficult. In this process, a single-headed nozzle and a double-headed nozzle must be kept on hand at all times, resulting in problems such as the loss of replacement nozzles during spraying operations. Furthermore, even if the nozzle of such a nozzle exchange type atomizer was replaced, the spray form (range) could only be changed from single head to double head.

[Purpose of the invention] Therefore, the present invention enables one nozzle to be replaced with a single-headed nozzle or a double-headed nozzle, and by converting the worm member housed in the nozzle cap, the discharge spray can be improved. It is an object of the present invention to provide a double-headed nozzle for an atomizer that allows the spray form of liquid to be easily changed.

[Main points of the invention] In order to achieve the above object, the present invention removes a double-headed nozzle consisting of a branch pipe and a nozzle cap from the liquid supply pipe, and attaches the nozzle cap of this double-headed nozzle to the tip of the liquid supply pipe. It can be easily converted to a single head type by attaching it to the
By changing the worm member housed in the nozzle cap, the spray form to be discharged can be made arbitrary, and the branch pipe, the spray nozzle, and the worm member are molded separately.

[Configuration of Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

Reference numeral 1 in FIG. 1 is a liquid feeding tube through which the spray liquid is sent out from the sprayer main body, and the figure shows only the tip thereof. An O-ring 2 is attached to the tip of the liquid feeding pipe 1 to prevent leakage of the spray liquid.
At the tip of this O-ring 2, a male thread-shaped connection screw attachment part 3 is formed, and at the tip of this connection screw attachment part 3, a cylindrical protrusion 4 whose tip tapers into a truncated cone shape is formed. has been done. A through hole 5 penetrating from one side to the other side is bored in the cylindrical part of this protrusion 4, and this through hole 5 communicates with the liquid feeding path 6 of the liquid feeding pipe 1, so that the spray liquid is sent out. ing. Further, a pair of communication grooves 7, 7 are provided on the side surface of the truncated cone portion of the protrusion 4.
is formed diagonally.

A branch pipe 8 having a male thread formed on the inner circumferential surface of the proximal end is screwed onto the male threaded connecting screw attachment part 3, and this branch pipe 8 is connected to an annular main pipe 8a and an outer circumferential surface of the main pipe part 8a. Branch pipe portion 8 formed by more discharge
b, 8b. A male threaded portion 9 is formed on the outer circumferential surface of the branch pipe portions 8b, 8b of this branched pipe 8, and an O-ring 10 for preventing spray liquid leakage is attached to the tip of this male threaded portion 9. Further, spray nozzles 11, 11 are provided at each tip of the branch pipe portions 8b, 8b.
are rotatably attached around the branch pipe parts 8b, 8b to form a double-headed nozzle, and the branch pipe parts 8b,
Ring nut 1 screwed into male threaded part 9 of 8b
2 to the spray nozzle 11, the spray nozzle 11 can be tilted and fixed with respect to the branch pipe 8.

In addition, each spray nozzle 1 of the above-mentioned double-headed nozzle
The tip portions 1 and 11 have exactly the same dimensions as the tip of the liquid feeding tube 1 described above. That is, at the tip of each spray nozzle 11, the connection screw attachment part 3 is attached.
A tip screw attachment part 14 and a protrusion 15 having the same dimensions as the protrusion 4 are formed. Furthermore, a through hole 16 is bored inside each of the spray nozzles 11, 11, and a through hole 16 is formed on the outer periphery of an umbrella-shaped portion 17 at the tip, and is provided with a predetermined swirling force to apply a predetermined swirling force to the spray liquid to be discharged. An insertion shaft portion 17b of the insect member 18 formed with communication grooves 17a, 17a (see FIG. 2) is inserted therein.

Further, the tip screw attachment portions 14, 14 are provided with nozzle caps 19, 19 having male threads formed on the inner peripheral surface.
are screwed onto the nozzle caps 19, 19, respectively.
and each of the spray nozzles 11, 11 is provided with the O
O-rings 13, 13 having the same dimensions as ring 2 are attached. Furthermore, both nozzle caps 1
A spout 20 is provided at the top of the tips of the tips 9 and 19. These nozzle caps 19, 19 are connected to the connecting screw attachment portion 3 having the same dimensions and configuration as the tip screw attachment portion 14.
It can also be attached to a single head nozzle.

Note that FIG. 3 shows the cross-sectional configuration of the nozzle tip, and FIG. 4 shows the cross-sectional configuration.

[Configuration of Example] Next, the usage state of the nozzle of the sprayer configured as described above will be described.

That is, in order to perform double-headed nozzle spraying, as shown in FIG. each spray nozzle 11,
The nozzle caps 19, 19 may be screwed into the tip screw attachment portions 14 at the tips of the nozzle caps 11, respectively.

When the spray liquid is pressurized and sent into the liquid feed path 6 using a liquid feed pump or the like, the spray liquid is pushed out from the through hole 5, passes through the main pipe part 8a and branch pipe part 8b of the branch pipe 8, and enters the spray nozzle 11. The liquid is pushed out into the nozzle cap 19 through the liquid feeding path, that is, the through hole 16 through which the insertion shaft 17b of the worm member 18 is inserted, and passes through the connecting groove 17a of the umbrella-shaped portion 17 formed at the tip of the worm member 18. By doing so, a predetermined turning force is applied, and finally the spray port 2 of the nozzle cap 19
It is discharged in a mist form from 0.

By the way, in order to change the above-mentioned double-headed nozzle to a single-headed nozzle, the branch pipe 8 is removed from the connection screw attachment part 3 of the liquid feeding tube 1, and the nozzle cap 19 is attached to the tip screw attachment part 14 of the spray nozzle 11. This is done by directly attaching the removed nozzle cap 19 to the connection screw attachment part 3 of the liquid feeding pipe 1.

In this way, you can create a single-head nozzle by simply removing the nozzle cap 19 of a double-head nozzle and attaching it to the connection screw attachment part 3 of the liquid feed pipe 1 as described above, without having to prepare a special single-head nozzle. It can be done.

In addition, in the above double-headed nozzle, each spray nozzle 1
1 and 11 can be fixed at an angle with respect to the branch pipe 8, it is also possible to change the spray direction arbitrarily.

Also, a branch pipe 8, a spray nozzle 11, a worm member 18
Since it is molded separately, it can be easily processed.

In addition, the present invention can apply different swirling forces to the discharged liquid by converting the worm member 18 disposed in the nozzle cap 19 into another worm member 18, and the spray form (range) can be easily changed. It is also possible to change.

[Effects of the invention] As detailed above, the present invention can be used as a double-headed nozzle, and the nozzle cap attached to the tip screw attachment part can be removed and this nozzle cap can be formed at the tip of the liquid feeding tube. When attached to the connecting screw attachment part, it can be used as a single-head nozzle, and mutual conversion is possible without having to prepare a single-head nozzle, so the number of parts can be reduced accordingly, and it can be used as a single-head nozzle. It is economical because replacement parts are not lost. Further, the spray form can be easily changed to various types simply by replacing the insect member.
