The outer wall of the flange is fused to the outer wall of the upper portion of the outer casing and has a continuous surface.

The inlet hole has an inlet pipe outside, and the inlet pipe has an annular step on the inner wall of the inlet pipe to form a venturi; the downstream of the annular step has a suction port connecting the outer wall of the inlet pipe Stomata.

The water inlet pipe further has a water source for generating electricity before the venturi; the outer casing and the upper cover are both made of a transparent material.

For the water outlet hole, the cross section may be rectangular or circular.

The beneficial effects brought by the invention are:

1. The hollow annular shower structure not only realizes the function of converging collision water flow, but also saves the central parts such as the cover, greatly reduces the cost of the shower, and realizes the function with the least material;

2. The use of the upper cover and the outer casing realizes the converging water flow hole, which greatly reduces the production cost and simplifies the production process;

3. The venturi structure with suction holes on the inlet pipe makes the shower water flow with air bubbles for improved comfort;

4. The shower made of transparent material and the light source of hydroelectric power make the shower have unique aesthetic significance.

detailed description

Embodiment 1, as shown in FIG. 1, only three main components in the hollow shower embodiment of the present invention are the upper cover 1, the outer casing 2 and the handle 3. The upper cover 1 is a hollow annular body, which is divided into a gap section and a matching section according to the axial direction. The gap section has a top annular flange 101 and an outer side surface 102; the outer casing 2 is a hollow annular body, which is divided into axial directions. The upper and lower sections have a smooth inner wall 201, and the lower section has a ring-shaped uniformly distributed groove 203 and a convex smooth surface 202 between the grooves; the inlet pipe 21 communicates with the inner wall 201 of the outer casing 2, and passes through the fixing bolt 4 and the handle 3 assembly and fixed.

The details between the various components are further illustrated in the cross-section of Figure 2. As shown in the figure, an annular cavity 12 is formed between the upper cover 1 and the outer casing 2, and the convex smooth surface 202 of the lower periphery of the annular cavity 12 is fixed by the lower outer surface portion of the upper cover 1 to make the groove The front ports of the 203 are formed with water outlet holes 204. The water outlet holes are square in cross section; all the water outlet holes 204 converge at a point in the exit direction, as shown by the direction of the arrow in the figure, which is the actual flow direction of the water flow. After the annular chamber 12 is filled from the inner lumen of the handle 3, all of it flows out through the water outlet hole 204.

The bottom surface of the groove 203 uniformly distributed in the lower portion of the outer casing 2 is a lower inclined surface.

3 is a perspective view of the first embodiment, which can be seen that the embodiment is very simple, the process is simple, and the number of parts is small.

Embodiment 2, as shown in FIG. 4, in the second embodiment, the structure of the upper cover 1 and the outer casing 2 is the same as that of the first embodiment, that is, the same flange 101 and the upper outer wall 102 of the upper cover are integrated into the outer casing. Smooth inner wall 201, groove 203 and raised smooth surface 202. The difference is that there is no longer a separate handle 3, and the handle has been integrally formed with the outer casing 1. In addition, a light source 301 with a power generating device and a port 302 to which the light source 301 is mounted are provided at the end of the handle.

The details of the components of Fig. 4 and other differences from the first embodiment are shown in Fig. 5; an annular cavity 12 is formed between the upper cover 1 and the outer casing 2, and the outer surfaces of the upper cover 1 and the outer casing 2 are both The fusion process makes the surface of the annular structure of the entire shower more smooth and aesthetic; the groove 203 forms a water outlet hole 204 with the upper cover 1, and the water outlet hole 204 still has a square cross section; in the handle portion, compared with the first embodiment There are two differences, one is that the handle portion is connected with the outer casing, and the lumen has an annular step 303 (ie, a reduced diameter section), and the structure forms a structure of a venturi; the annular step 303 is adjacent to the outer casing The portion has a suction hole 304 such that air is drawn into the water path due to the venturi effect at the suction hole 304, and the mixed water flow is output from the water outlet hole 204, so that the shower has a comfortable spray with bubbles. The light source 301 with the power generating device generates electricity due to the continuous pressure of the water flow, and the light source supplied thereto is turned on, thereby lighting the shower made of the entire transparent material, and has a unique aesthetic.

The perspective view of the second embodiment can be seen from FIG. 6, which is as simple as the first embodiment and more aesthetic.

The above is only the preferred embodiment of the present invention, and thus the scope of the present invention is not limited thereto, that is, equivalent changes and modifications made in accordance with the scope of the invention and the contents of the specification should still be covered by the present invention. Within the scope.
