Description

Falling head structure

The present invention relates to a downspout structure, and in particular to a downspout structure that prevents insects or gases from entering the room.

Water pipes are often used to direct the direction of liquid flow. For example, when the water pipes are installed in the bathroom, the water in the bathroom can be transported to the outdoors (or the sewage tank) via the water pipes, but the water pipes are connected to the outdoors (or sewage). The tank and the bathroom, so insects or gases in the outdoor (or sewage tank) can also enter the bathroom (or indoors) along the water pipe.

Therefore, insecticides are generally sprayed in the bathroom (or indoors) to prevent insects from entering the bathroom (or indoors), or plugging the nozzles with a plug, but the inconvenience is also relatively caused.

The main purpose of this creation is to provide a drop head structure for installation in a water pipe to prevent insects or gases in the outdoor (or sewage tank) from entering the bathroom (or indoors) along the water pipe.

A drop head structure of the present invention comprises a ring wall, a bottom plate and a compartment, the ring wall is combined with the bottom plate, the compartment is located above the floor, the ring wall surrounds the compartment, the ring wall has an inner ring wall and an outer wall a ring wall having an opening for allowing liquid to flow into the chamber, wherein the ring wall is provided with at least one overflow hole communicating with the inner ring wall and the outer ring wall, the opening, the chamber And the overflow The flow hole defines a liquid flow channel having a first opening and a second opening, the first opening is located at the inner ring wall, the first opening is connected to the chamber, and the second opening is located at the outer ring wall The first opening has a top edge, the second opening has a bottom edge, a first horizontal plane passes through the top edge of the first opening, a second horizontal plane passes through the bottom edge of the second opening, and the first A horizontal plane is not higher than the second horizontal plane, so that a first water storage tank is formed between the second horizontal plane and the bottom plate.

When a liquid accumulates in the first water storage tank, insects in the outdoor (or sewage tank) can be prevented from crawling into the room through the water pipe, and the gas in the outdoor (or sewage tank) can be prevented from entering the room through the water pipe.

Referring to Figures 1, 2 and 3, which is a first embodiment of the present invention, a water drop head structure 100 includes a ring wall 110, a bottom plate 120 and a compartment 130, the ring wall 110 being coupled to the bottom plate 120, The chamber 130 is located above the bottom plate 120. The ring wall 110 surrounds the chamber 130. Preferably, the ring wall 110 and the bottom plate 120 are integrally formed. In this embodiment, the ring wall 110 is a tapered ring. wall.

Referring to Figures 1, 2 and 3, the ring wall 110 of the downspout structure 100 has an inner ring wall 111 and an outer ring wall 112. The chamber 130 has an opening 131 for liquid to flow into the chamber. In the 130, the annular wall 110 is provided with at least one overflow hole 113 communicating with the inner ring wall 111 and the outer ring wall 112. The opening 131, the chamber 130 and the overflow hole 113 constitute a liquid flow channel A. The overflow hole 113 has a first opening 114 and a second opening 115. The first opening 114 is located in the inner ring wall 111, and the first opening 114 communicates with the chamber 130. The second opening 115 is located at the outer ring wall. 112, the first opening 114 has a top edge 114a, and the second opening 115 has a bottom edge 115a.

Referring to FIGS. 1 and 3, a first horizontal plane X1 passes through the top edge 114a of the first opening 114, a second horizontal plane X2 passes through the bottom edge 115a of the second opening 115, and the first horizontal plane X1 is not high. In the second horizontal plane X2, a first water storage tank B is formed between the second horizontal surface X2 and the bottom plate 120. In this embodiment, the first horizontal surface X1 is lower than the second horizontal surface X2, the first opening The top edge 114a of the 114 is located in the first water reservoir B.

Referring to Figures 1, 2 and 3, in the present embodiment, the overflow hole 113 is a non-bending hole, and the overflow hole 113 is substantially a straight through hole passing through a vertical line Y of the first horizontal plane X1. There is an angle E between a center line Z passing through the overflow hole 113, and the angle E is an acute angle.

Referring to Figures 1, 2 and 3, the water drop head structure 100 further includes a support ring 150 coupled to the outer ring wall 112 of the ring wall 111. In this embodiment, the The support ring 150 is integrally formed with the ring wall 110.

Referring to Figures 2 and 4, a water pipe 200 is disposed on a floor 300, one end of which is located on the floor (such as a bathroom or kitchen interior floor, etc.), taking the bathroom as an example, usually one of the water pipes 200 A support member 400 is disposed at the end, and the support member 400 is covered by a cover 500. The cover 500 has a plurality of through holes 510. The through holes 510 communicate with the water pipe 200 to open the cover 500 and The water drop head structure 100 is mounted to the support member 400, and the chamber 130 communicates with the water tube 200 through the overflow hole 113.

Referring to Figures 2, 4 and 5, the cover 500 is covered, and liquid in the bathroom can flow to the chamber 130 through the through holes 510, since the chamber 130 and the overflow hole 113 constitute the liquid flow. Channel A, so liquid can flow into the water pipe 200 via the liquid flow channel A, or in different cases, the support member 400 and the cover 500 are not provided at one end of the water pipe 200, and the water head structure 100 It can still be directly installed in the water pipe 200.

Referring to FIGS. 3 and 5, when the liquid stops flowing, the liquid may accumulate in the first water storage tank B between the second horizontal surface X2 and the bottom plate 120. In this embodiment, the first opening 114 The top edge 114a is embedded in the liquid accumulated in the first water storage tank B, so that the overflow hole 113 is sealed by the liquid in the first water storage tank B, thereby preventing insects in the outdoor (or sewage tank) and Gas enters the room via the water pipe 200.

Referring to Figures 2 and 6, the water drop head structure 100 can also be installed in a drain hole 610 of a bathtub 600 (or a water tank). The drain hole 610 is connected to a water pipe 700. The water head structure 100 is installed. Provided in the drain hole 610, when the bathtub 600 (or the sink) stores water, a sealing cover 800 seals the opening 131 of the chamber 130 to prevent water from being lost from the liquid flow passage A of the water drop head structure 100. .

Referring to FIGS. 7 and 8, a second embodiment of the present invention differs from the first embodiment in that the water drop head structure 100 further includes an outer ring wall 140, and the outer ring wall 140 is coupled to the ring wall 110. The outer ring wall 140 and the ring wall 110 have a second water storage tank C. The outer ring wall 140 has a exposed end 141. The exposed end 141 and the ring wall 110 have an overflow port D. In this embodiment, the ring wall 110 and the outer ring wall 140 are integrally formed.

Referring to FIGS. 7 and 8, a third horizontal plane X3 passing through the exposed end 141 is not lower than the second horizontal plane X2. In this embodiment, the second horizontal plane X2 is lower than the third horizontal plane X3 when the liquid stops. When flowing, the liquid is accumulated in the first water storage tank B between the second horizontal surface X2 and the bottom plate 120, and accumulated in the second water storage tank C between the outer annular wall 140 and the annular wall 110. Since the third horizontal plane X3 is not lower than the second horizontal plane X2, the overflow hole 113 can be sealed by the liquid in the first water storage tank B and the liquid in the second water storage tank C, thereby preventing Insects and gases in the outdoor (or sewage tank) enter the room via the water pipe 200.

The scope of protection of this creation is subject to the definition of the scope of the patent application, and any changes and modifications made by those skilled in the art without departing from the spirit and scope of this creation are within the scope of protection of this creation. .
