Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an iron spray device for general household use.

Conventional structure and problems thereof Conventionally, in this type of iron spray device, as shown in FIG.
and a nozzle body 7 having a core 5 and a water supply channel portion 6.
These were generally constructed by ultrasonic welding.

However, with this configuration, if a defective spray occurs due to foreign matter such as dirt entering the spray device, it cannot be disassembled because the nozzle head 4 and nozzle body 7 are ultrasonically welded, and the foreign matter inside the spray device cannot be disassembled. There was a problem that it could not be removed and the problem of poor spraying could not be solved.

In addition, in a disassembleable spray device, as shown in FIG. 2, a nozzle head 9 having a nozzle hole 8 and a nozzle body 10 are connected via a packing 11, and a space 12 in the middle of both is connected.
is provided with a check valve 13 and a core 15 having a guide groove 14 at the top for spouting water in a swirling state from the nozzle hole 8;
Generally, a spring 16 was interposed between the two. However, with this configuration, the number of parts that make up the spray device is large;
There were problems in that the cost was high and assembly workability was very poor.

Purpose of the Invention The present invention solves these problems, reduces the number of component parts of the spray device, reduces costs, and
In addition to improving assembly work, the spray device has a disassembled structure that allows foreign matter to be removed from inside the device.
To provide an iron spray device that can maintain stable spraying.

Structure of the Invention The iron of the present invention includes a cylindrical nozzle head with a spray hole formed in the center of the tip surface, and a front open end surface that has the same diameter as this nozzle head and is joined to a rear open end surface of the nozzle head through packing, and It is integrally formed with a cylindrical nozzle body that communicates with a pump that sucks up water from a water tank and sends it out, and a water supply channel inside this nozzle body.
The forward protruding portion serves as a water passage; the nozzle head is provided with a core that projects into the inner circumference of the nozzle head at a distance, and a plurality of holes are provided on one of the outer circumference of the rear open end of the nozzle head and the outer circumference of the front open end of the nozzle body. A connecting pawl is formed on the other side, and a plurality of pawl receivers are formed on the other side to which these connecting pawls removably engage.With this configuration of the nozzle head and nozzle body, if the nozzle head and nozzle body are joined through packing, the spray can be made. Since the device can be formed, the number of parts is small, it can be disassembled for cleaning, and stable spraying can be maintained.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 3 to 5, 17
is the base with the heater 18, 19 is the base 1
A heat insulating board placed on top of 7, 20 is this insulating board 19
22 is a pump device that sends the water in the tank 21 to the spray device 24 through the water conduit 23, and 25 is a handle cover disposed on the handle 20. The upper part of the above-mentioned pump device 22 forms a button section 26 that protrudes from the above-mentioned handle cover 25.

Next, to explain the structure of the spray device 24 in detail, 27 is a nozzle head, which is formed by a cylindrical part 29 having a spray hole 28 in the center of the upper surface, and a groove-like groove inside the cylindrical part 29. Canal 3
0 are formed in a plurality in the longitudinal direction, and a plurality of connecting claws 31 are formed on the outside. 32 is the nozzle body,
It is formed by a core 33 and a water supply channel 34 having an outer diameter larger than the outer diameter of the core 33.
A guide groove 35 is integrally formed in the upper part of the tube to give swirling force to the water. Further, on the outside of the water supply channel portion 34, a plurality of pawl receiving portions 36 are formed at positions facing the joining pawls 31 of the nozzle head 27. 37
is a packing that prevents water from leaking from the joint between the nozzle head 27 and the nozzle body 32.

In the above configuration, when foreign matter such as dirt gets mixed into the water in the tank 21, the foreign matter is sent to the spray device 24 by operating the pump device 22.
The spray device becomes clogged, resulting in poor spraying. In this case, by prying the joint claw 31 of the nozzle head 27 and removing it from the claw receiver 36, the spray device 24 can be easily disassembled and foreign matter stuck inside can be removed, allowing stable spraying to be maintained. There is an effect.

In the above embodiment, the nozzle head 27 is provided with the connecting claw 31, and the nozzle body 32 is provided with the claw receiving portion 36.
Although an example in which the nozzle head 27 is provided with a pawl receiving portion 36 and a joint pawl 31 is provided on the nozzle body 32 is shown, the nozzle head 27 may also be provided with a connecting pawl 31.
and a nozzle body 32 with a mating claw 31 and a claw receiving part 3.
6 may be provided. In short, any spray device may be used as long as the nozzle head and nozzle body are removably joined by a connecting claw and a claw receiver.

Effects of the Invention As is clear from the above embodiments, the iron spray device of the present invention is particularly constructed by joining a nozzle head and a nozzle body by a connecting claw and a claw receiver provided on the nozzle head or nozzle body. The number of parts is small, reducing costs, and the structure allows for assembly and disassembly, so if a spray problem occurs due to foreign matter such as dirt, it can be disassembled and cleaned, making it possible to maintain a stable spray. It is possible.
