Spraying device

Abstract

The present invention provides a water spouting device that, in a fluid element utilizing Karman vortices, can prevent the inner wall surface of the vortex generating portion from expanding and deforming to prevent generation of the water spouting port even when the water spouting port is formed of an elastically deformable soft member. The phenomenon of the anticipated Karman vortex. A water spouting device that spits out hot and cold water while vibrating back and forth. It has a water spouting device body and a vibration generating element. The vibration generating element has a water supply channel, a vortex generation channel and a water spout channel. The water spout channel is made of an elastically deformable soft member. It is formed and installed on the water spouting device body in a manner that the user can deform the water spout channel. The vortex generating channel will not expand or deform even when the internal pressure increases due to the supply of hot and cold water from the water supply channel.

Description

technical field [0001] The present invention relates to a water discharge device that discharges hot and cold water while vibrating back and forth. Background technique [0002] The following Patent Documents 1 to 3 describe water discharge devices utilizing the oscillation phenomenon of a fluid element. These water discharge devices can change the spraying direction of discharge water without providing a movable member, and thus have the advantage of being able to realize a discharge device capable of spraying water over a wide range with a simple and compact structure. [0003] The water spouting device described in the following patent document 3 is as Figure 13 As shown, the fluid flowing into the antechamber 110 from the inlet hole 114 first collides with an island-shaped obstacle 116 with a triangular cross-section in the antechamber 110 . Once the fluid collides, on the downstream side of the obstacle 116, the upper side and the lower side of the obstacle 116 will a...

Problems solved by technology

Therefore, once the inner wall surface of the vortex generating part expands and deforms, the size of the above-mentioned gap becomes larger (no longer the specified size), and the expected vortex may not be generated.

In this way, if the expected vortex cannot be generated, the amplitude and vibration cycle of the jetted water will also change, causing the problem that the expected jetted water cannot be realized.
