Referring to the second and third figures, the flow guiding structure 8 includes a first convex portion 81, a second convex portion 82 and a third convex portion 83. The protrusions 81, 82, 83 extend from the elastic diaphragm 4 to face an upper surface 40 of the water storage chamber 20. When the elastic diaphragm 4 abuts against the two pipe joints 6 (as shown in the fourth figure), the flow guiding structure 8 separates the upper surface 40 of the elastic diaphragm 4 from the inner wall surface 270 of the inner liner 27, A flow guiding passage 80 is maintained between the two pipe joints 6 in the water storage chamber 20 of the tub body 2, thereby keeping the water flow between the two pipe joints 6 smooth. In this embodiment, the flow guiding structure 8 is integrally formed on the upper surface 40 of the elastic diaphragm 4, but not limited thereto. The flow guiding structure 8 may also be formed on the inner wall surface of the inner liner 27. 270.

As shown in the second figure, the first convex portion 81 is directly opposite to the pipe joint 6 on the top surface of the upper tub 21, and the second convex portion 82 is directly opposite to the other pipe joint 6 located on the side of the upper tub 21. As shown in the third figure, the first protrusion 81 includes a plurality of ribs 812 and a plurality of protrusions 814. The ridges 812 are arranged substantially radially, and the protrusions 814 are spaced apart from the protrusions. Strip 812 peripheral. The second protrusion 82 includes two intersecting ribs 822. Since the elastic diaphragm 4 is preferably formed by injection molding, and the drawing direction of the mold is parallel to the side wall 47, the two protrusions 822 of the second convex portion 82 of the side wall 47 are preferably The electrodes intersect perpendicularly to facilitate the removal of the elastic diaphragm 4 from its mold. The third convex portion 83 includes a plurality of spaced-apart bumps 830 extending from the first convex portion 81 to the second convex portion 82.

The channel 802 and the two gaps 801 together form the flow guiding channel 80, as shown in the fifth and sixth figures, whereby the water flow can flow from the outside of the pressure tank 1 through the one of the pipe joints 6 into the flow guiding channel 80, and The guide through the flow guiding passage 80 smoothly flows to the other pipe joint 6 as indicated by an arrow in the figure, and finally flows out of the pressure tank 1.

Compared with the prior art, the pressure drum provided by the present invention has two pipe joints for feeding water into and out of the pressure tank, and is formed between the two pipe joints by the flow guiding structure disposed in the water storage chamber. The flow guiding channel is provided such that the water flow can smoothly flow between the two pipe joints along the flow guiding channel even if the elastic diaphragm is in a state of abutting against the two pipe joints.

Referring to the second and third figures, the elastic diaphragm 4 preferably defines a first convex pad 491 and a second convex pad 492 formed on the lower surface 49 of the elastic diaphragm 4 facing the pressure chamber 25. The first convex pad 491 and the second convex pad 492 are respectively opposite to the first convex portion 81 and the second convex portion 82 and larger than the two pipe joints 6 . The first protrusion 491 and the second protrusion 492 are used to increase the thickness of the pressed portion of the elastic diaphragm 4 facing the inner hole 60 of the two pipe joints 6 to prevent the pressure portion of the elastic diaphragm 4 from being pressed. In the state where the elastic diaphragm 4 is pushed to the two pipe joints 6, the strong pressure is pushed into the inner holes 60 of the two pipe joints 6, causing the elastic diaphragm 4 to be easily broken under repeated use for a period of time. In addition, the elastic diaphragm 4 is preferably formed by injection molding, but the thickness of the second protrusion 492 is generally smaller than the thickness of the first protrusion 491 in consideration of ease of manufacture. Therefore, in order to strengthen the pressure resistance of the elastic diaphragm 4 to the pressed portion of the inner hole 60 of the other pipe joint 6 (particularly, the pressure receiving portion facing the center of the inner hole 60), the second convex portion 82 is provided. There is a bump 820 that is centered on the inner bore 60 of the other pipe joint 6, as shown in Figures 3 and 6. In this embodiment, the bump 820 is a portion where the two second ribs 822 intersect perpendicularly, but is not limited thereto.
