Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an iron spray device used in general households.

BACKGROUND TECHNOLOGY Conventionally, this type of iron spray device has adopted a configuration as shown in, for example, Japanese Patent Application Laid-open No. 101200/1983, and specifically, the spray device shown in FIG. 4 and FIG. It was becoming like that.

That is, a nozzle cover 2 provided with a small hole 1,
Water is supplied by a pump device (not shown) to a spray nozzle 5, which is integrally formed with a nozzle body 4 provided with a spraying portion 3 by welding, for spraying.

Problems to be Solved by the Invention However, with such a configuration, extremely high precision is required in the welding conditions between the nozzle cover 2 and the nozzle body 4, and variations in component dimensions and welding conditions make it difficult to spray water well. In addition, there was a problem in that the workability of assembling the spray nozzle inevitably deteriorated due to its management.

This is due to the following reasons. First, the important point for good water spraying is the nozzle cover 2.
and the nozzle body 4, and this H is 0.
When H>0, the spraying part 3 does not rotate properly and the water directly comes out of the small hole 1 without being turned into a mist. In addition, when H<0, the spraying part 3 is deformed by the pressure applied during welding, so water cannot be swirled appropriately and good spray cannot be obtained.

Second, the water needs to be swirled properly to get a good spray. Therefore, high water pressure is applied to the spray nozzle, and the welded portion 6 between the nozzle cover 2 and the nozzle body 4 needs to have sealing properties that can withstand this water pressure.

In other words, it is difficult to satisfy both the gap dimension H and the sealing performance, and it is also difficult to manage them, so that not only is it impossible to spray water well, but the workability is also poor. .

Therefore, the object of the present invention is to make it possible to obtain a specified gap size H and sealing performance with a simple structure, and to improve the ease of assembling the spray nozzle.

Means for solving the problems In order to achieve the above purpose, the present invention
A tank that stores water, a pump device that discharges the water in the tank, a spray nozzle that sprays the water from the pump device, and is made of an elastic material, and the pump device and the spray nozzle are connected. The spray nozzle includes a nozzle cover having a spray hole and attached to the outlet side of the water channel, a core disposed within the nozzle cover, and one end of the core surrounding the spray hole. The sprayer has a dispersing portion that is in contact with the inner surface of the nozzle cover and formed on at least one of the nozzle cover and the core, and the core is integrally formed with the waterway.

Effects The iron spray device of the present invention has the above-mentioned structure, so that the core can be made of an elastic material, and by attaching the nozzle cover to the water channel, the core can be moved toward the nozzle cover side using this elastic force. You will be able to press it. Therefore, variations in dimensions of the core and nozzle cover can be absorbed, and the gap dimension H can be reduced to zero.

In addition, since the core is integrated with the waterway,
The spray nozzle can be easily assembled by simply attaching the nozzle cover to the water channel, and at the same time, a predetermined sealing performance can be ensured, making it possible to improve the ease of assembling the spray nozzle.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 3, 7 is a base having a heater 8, 9 is a heat insulating plate placed on the base 7, 10 is a tank for storing water composed of a plurality of tank members 11 and 12, and 13 is the tank 10. A pump device 17 sends water from the tank 1 to a spray nozzle 16 through a water conduit 14 and a water channel 15 made of an elastic material such as rubber.
0, the tank cover 18 is an operation button protruding from the tank cover 17, and the operation button 18 drives the pump device 13,
Water is supplied into the tank 10 to a spray nozzle 16 for spraying.

Next, the configuration of the spray nozzle 16 will be described in detail. 19 is a nozzle cover formed in the shape of a cylinder with a bottom and provided with a spray hole 20 in the center of the bottom;
A plurality of connecting claws 22 are formed on the outside of the cylindrical portion 21. A core 23 is formed integrally with the water channel 15, and is formed of a cylindrical portion 24 having an outer diameter smaller than the inner diameter of the cylindrical portion 21. 25 is the core 23
The spraying section 25 and the cylindrical section 24 are provided integrally with the water channel 15 and are made of an elastic material such as rubber. Also, this core 23
The water supplied from the water channel 15 is passed through the water supply channel 26 formed between the cylindrical part 21 and the cylindrical part 24,
A notch 27 is formed to lead to the dispersion section 25. Reference numeral 28 designates a nozzle cover receiver having a plurality of claw receivers 29 at positions facing the joint claws 22 of the nozzle cover 19. The nozzle cover 19 is placed over the core 23, and the joint claws 22 are inserted into the claw receivers 29. By fitting, the spraying part 25 is pressed against the inner surface of the nozzle cover 19 so as to surround the spray hole 20 and comes into close contact with the inner surface of the nozzle cover 19, thereby forming a spray nozzle 16.

Next, the operation of the configuration of this embodiment will be explained. First, water supplied by the pump device 13 passes through the water channel 15 and is sent from the notch 27 of the core 23 to the water channel 26, and after being given a swirling force by the spraying part 25, the water is sent to the spray hole 20 of the nozzle cover 19. It turns into mist and is sprayed.

Since the core 23 is integrally formed with the water channel 15 made of an elastic material such as rubber, the nozzle cover 19 is placed over the core 23 and the connecting claws 22 are inserted into the claw receivers. Since the dispersion section 25 of the core 23 is pressed against the nozzle cover 19 when it is fitted into the nozzle cover 19, it can be brought into close contact with the inner surface of the nozzle cover 19, absorbing dimensional errors of the parts, and dispersing the dispersion section. The gap dimension H between the nozzle cover 25 and the inner surface of the nozzle cover 19 can always be set to 0, and good spraying can be obtained.

Moreover, since the core 23 is integrated with the water channel 15, by covering the core 23 with the nozzle cover 19 and fitting the connecting claws 22 into the claw receivers 29, the nozzle cover can be removed. 19 and the water channel 15 at the same time, the gap size H can be managed and a predetermined sealing property can be obtained at low cost with a simple configuration, and the ease of assembling the spray nozzle can be improved.

Furthermore, in the embodiment of the present invention, the nozzle cover 1
9 is removable, so even if foreign matter such as dust gets clogged inside the spray nozzle 16, it can be easily disassembled by removing the nozzle cover 19 from the water channel 15, and the foreign matter clogged inside can be removed. can be easily removed. Therefore, good spraying can be stably performed over a long period of time.

In addition, in the example, the dispersion part was formed in the core, but
It may be provided on the nozzle cover side.
