Description

[Detailed Description of the Invention] The present invention relates to an improvement of the injection nozzle of a human body private parts washing device for washing private parts such as the anus with warm water after defecation.

Conventionally, this type of water jet nozzle has a plurality of small holes provided at the tip of the nozzle, but it has the following drawbacks.

(1) Organic or inorganic substances contained in the water solidify in the small holes, or the small holes become narrower so that no water comes out, or the height of the water jet is unstable regardless of water pressure. Ta.

(2) Even if a needle or the like was used to clean the small hole, it was difficult to remove the solid matter.

(3) In manufacturing nozzles with small holes, it was expensive to drill the small holes with high precision at a certain angle.

The present invention is an improvement on the above-mentioned drawbacks, and will be explained based on the following embodiments. In Figures 1 to 5, 1 is a human body private parts cleaning device, 2 is a toilet bowl, 3 is a hot water tank, and 4 is a dryer. A hot air device, 5 is a lever, 6 is a nozzle body, and 7 is a nozzle head. 8a・8
b... is a small hole provided in the nozzle head, and in the conventional example, if 8a and 8b... are blocked by dirt or if the small hole is clogged due to organic or inorganic substances, it is extremely difficult to repair. Ta. Second
In Figure a, the nozzle head 7 is of a structure that is integral with the nozzle body 6, and in Figure 2b, the nozzle head 7 is tightly fitted into the nozzle body 6 and is of a structure that is very difficult to remove. Especially in recent years, there is a severe lack of manpower for maintenance of such parts, and since the human body private parts cleaning device is a special device, it is extremely troublesome even if it breaks down even in a short period of time. To provide a nozzle head that can be easily installed and removed by a housewife with a single screwdriver. Describing one embodiment of the present invention, reference numeral 6 denotes a nozzle body provided with a through hole 9, and a threaded portion 9a is formed on the inner periphery of the tip end of the through hole 9. This screw part 9
a is screwed into a threaded portion 12a formed at one end of the nozzle head threaded member 12. Thus, a ring-shaped nozzle head 10 is held between the tip of the nozzle body 6 and a flange 12b provided at the other end of the nozzle head screw member 12 and protruding outward in the radial direction. The nozzle head screw member 12 includes an axial flow channel 13 that is concentric with and communicates with the through hole 9, and a radial flow channel 14 that communicates with the axial flow channel 13 and opens outward in the radial direction. ing. And through hole 9,
The cleaning water that has passed through the flow channel 13 and the radial flow channel 14 is injected into the private parts of the human body through nozzle holes 10a...10e that penetrate the nozzle head 10 in the radial direction. Reference numeral 11 denotes an O-ring, which is used for sealing between the collar 12b of the nozzle head screw 12 and the tip of the nozzle body 6.

In such a nozzle configuration, the nozzle head 10 can be easily attached and detached with a single screwdriver.
It can be easily cleaned and replaced.

That is, (1) Even if the nozzle part having a large number of small holes becomes clogged, it can be easily removed and cleaned, and even an amateur can repair it.

(2) The nozzle head has a simple shape and is an independent part from the nozzle, so the nozzle diameter, inclination angle, etc. can be machined at low cost and with high precision.

(3) Since the cleaning water can be installed at an inclined angle so that the cleaning water is concentrated in localized areas, the amount of water used is small and the cleaning effect is high.

The present invention has the above-mentioned effects, and furthermore, it is difficult for dust to adhere to the nozzle head and nozzle screw, and it can be made of synthetic resin that does not rust. It is also possible to coat the metal nozzle head and nozzle screw with a resin material to prevent clogging due to the accumulation of inorganic substances, or to make the nozzle head and nozzle screw from earthenware or ceramics because the structure is simple.

As explained above, the nozzle head of the present invention is an extremely effective and highly practical nozzle head.
