Description

[Detailed description of the invention] The present invention relates to a water spouting nozzle, and more specifically, it relates to the improvement of a jet jet type water spouting nozzle. The six-pronged nozzle of the present invention is characterized by a structure in which the facing nozzle opening fully opens automatically under water pressure to powerfully spray cleansing water, and is easy to manufacture. It is used in various types of flush toilets such as other water-saving flush toilets, simple flush toilets, and urinals, and is also used as a water spouting nozzle for melting snow.

An example of implementation of the present invention will be described in detail below based on the drawings.

The drawing shows an example in which the nozzle A is installed in a flush toilet bowl, and the nozzle A is attached to the mounting wall B2 of the flush toilet bowl B with a nut 9. A nozzle contact body 2 is connected and communicated with the water supply pipe 8, and a nozzle contact body 2 is removably held in the picture bodies 1 and 2, and the cleaning water fed through the water supply pipe 8 is jetted and guided into the rectification space a of the nozzle front body 1. It is intercepted by the nozzle pipe 3.

The nozzle front body 1 has a rectification space a that opens toward the ball surface B1, and an inner vertical tube portion 4 is provided protruding from the rear wall 1b, and an insertion hole 5 is formed in the tube portion in communication with the rectification space a. At the same time, a threaded threaded portion 10 is provided on the outer peripheral surface of the tube portion to which the nozzle connecting body 2 is threadedly connected.

The nozzle connecting body 2 has an outer line pipe part 6 having a larger diameter than the inner vertical pipe part 4, and a female thread part 11 is provided on the inner peripheral surface of this pipe part 6.
It is threadedly connected to the inner vertical tube part 4, and a clamping part 7 of the flange 3b of the nozzle pipe 3 is formed between the opposing inner vertical tube part end 4a and the tube part bottom 6a.

Further, the nozzle contact body 2 connects the water supply pipe 8 with a coupling 12 to a rear end port communicating with a water channel opened at the center of the outer pipe bottom 6a.

The nozzle pipe 3 is made of a flexible material such as vinyl, preferably rubber, and is inserted through the insertion hole 5 and has a nozzle opening 3a at the tip extending from the insertion hole 5 into the rectification space a.
expands into a trumpet shape and comes into elastic contact with the inner wall surface 1a of the space a, while the other end reaches at least the inner vertical tube end 4a, and the flange 3b provided at the open end contacts the clamping portion 7. It is held in a pressure-bonded manner.

Therefore, the pipe length from the tip of the nozzle port 3a to the other end is:
The length is the same as the length between the inner wall surface 1a of the rectifying space a and the inner vertical pipe end 4a, or the length is such that the nozzle port 3a can be elastically contacted as shown in the drawing, or the length is such that watertightness is not lost due to surface tension. They are formed into lengths that are very closely spaced apart to the extent that they do not occur.

Further, in the contact relationship between the nozzle port 3a and the inner wall surface 1a,
The expanded surface may be made smooth to provide surface contact, or ribs 13 may be protruded to provide line contact.

The former is useful when the water supply pressure of wash water is low, and the latter is suitable when the pressure is high.

It is preferable that the ribs 13 are oriented radially so as not to impede the flow of the washing water.

As a result, when the water supply system is closed, the nozzle port 3a is closed and the water supply pipe 8 and the nozzle pipe 3 are filled with cleaning water.When the water supply system is closed, the nozzle port 3a is fully opened in response to the water supply pressure, and the cleaning water is flowed into the rectifying space a. The water is ejected from the ball onto the ball surface B1.

Therefore, since the valve function is provided at the spout position protruding from the ball surface, when the water supply system is opened, cleaning water can be stored in the channel leading to the nozzle port 3a, and the stored water can be used as a medium to be supplied at the same time as the tap is opened. Water pressure, for example, water pressure, is applied to the nozzle port 3a, and from the same port, which instantly opens the valve, water pressure cleaning water is jetted onto the ball surface from the beginning of the jet, and the water force powerfully cleans the ball surface. Therefore, it is particularly useful for simple flush toilets that flush with a small amount of flushing water, as well as flush toilets and urinals.

Further, even when a failure occurs in the toilet bowl and the ball surface is filled with dirty water, the nozzle opening 3a can prevent the ingress.

Additionally, in the above embodiment, the nozzle port 3a has a valve function, but the present invention is not limited to this, and it is also possible to at least secure the jet jet function of the cleaning water, and perform it without only the valve function. be.

Specifically, as shown in FIG.
It is molded to protrude uniformly and highly on eight sides, and is carried out so that a flow channel 14 is formed along the side of the rib 13 in a state in which it is in pressure contact with the inner wall surface 1a.

Thereby, when the water supply system is opened, the wash water in the water channel a flows out from the flow channel 14, and no wash water remains in the water channel a.

In this embodiment, there is no residual water and the nozzle does not freeze, so it is particularly useful as a water spouting nozzle for melting snow on roofs.

As described above, the present invention has a nozzle pipe length that extends from the inner wall surface in contact with the nozzle port to the end of the inner pipe part,
In addition, a flange is provided at the other end of the nozzle pipe, and this flange is held in the shape of a clamping lid by the clamping part, so this nozzle pipe is inserted from the end of the internal pipe part, and the flange is inserted into the opening of the same end. By inserting the tube until they abut, and then connecting the outer vertical tube section, assembly can be performed quickly and blindly.

At the same time as the assembly is completed, the nozzle opening comes into contact with or close to the inner wall surface and has a predetermined jet injection function that fully opens in response to water pressure, and the jet injection function can be performed without any separate adjustment. In addition, the flange is clamped at the clamping part to maintain and guarantee the jet injection function of the nozzle opening, and also serves as a backing to prevent water leakage from the joint between the front and rear parts of the nozzle. It is effective and has great practical benefits.

Therefore, it is extremely useful for flushing toilets or snow melting.
