Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a jet nozzle used for pine surge, for example in a bathroom.

[Conventional technology]

A conventional jet massage device has a jet jet hole provided on the inner wall of the bathtub, and jets a mixed fluid, which is a mixture of hot water and air supplied from a pump, into the bath from the jet jet hole.

This type of conventional device has the inconvenience of not being able to perform pine surgery on a desired part of the body because the position of the jet is fixed.Also, since only the jet jet is ejected, it is difficult to perform pine surgery with different stimulations. It was inconvenient that I couldn't do it.

In order to eliminate these inconveniences, the inventors of the present invention have devised a manually operated jet nozzle that can selectively switch between a jet jet and a shower jet to massage a desired part of the body.
However, in this conventional nozzle, a ball valve is provided in the nozzle head portion, and the jet jet flow and the shower jet flow are selectively switched by switching the flow path using the ball valve.

[The problem that the idea aims to solve]

The conventional nozzle mentioned above is convenient in that the jet flow can be switched at the hand of the nozzle head, but since the jet flow is switched using a ball valve, the thickness of the nozzle head becomes thicker. However, when the nozzle was attached to the wall of the bathtub, there was a problem in that the nozzle protruded significantly from the wall of the bathtub.

This invention was made in view of the above circumstances,
The purpose is to make the nozzle head thinner,
Another object of the present invention is to provide a jet nozzle with good operability.

[Means to solve the problem]

In order to achieve the above object, the present invention employs the following means. That is, in the jet nozzle of the present invention, the rear frame portion communicating with the main passage of hot water and the front frame portion provided with the jet nozzle and the shower nozzle are relatively rotatably fitted, and the inside of the front frame portion is As a means to solve the problem, the main passage is provided with a switching passage that connects the main passage to the jet nozzle at a predetermined rotational position and connects the main passage to the shower nozzle at another rotational position. Further, a first flow path leading to the jet nozzle and a second flow path leading to the shower nozzle are provided in the front frame, and a rotating frame is provided between the front frame and the rear frame. The rotary frame is provided so as to be rotatable through a required angle, and the rotary frame has a main passage communicating with the first flow passage at a predetermined rotation position;
Further, another means for solving the problem is provided with a switching passage that connects the main passage to the second flow passage at another rotational position.

[Effect]

In the case of a jet nozzle in which the front frame and the rear frame are relatively rotatable, when the front frame is rotated by a predetermined angle, the main passage communicates with the jet nozzle and the jet is discharged from the jet nozzle. When the jet is ejected and rotated to another rotational position, the main passage leads to the shower orifice from which the shower jet is ejected.

In the case of a jet nozzle in which a rotating frame is provided between the front and rear frames, when the rotating frame is rotated by a predetermined angle, the main passage communicates with the first flow passage, and a jet jet is ejected from the jet nozzle. However, when the main passage is rotated to another rotation position, the main passage communicates with the second flow passage, and a shower jet is ejected from the shower outlet.
