Description

Technical Field

[0001] The invention relates to the field of floor drains, and in particular to a floor drain device. Background Art

[0002] In daily life, for example, when washing machines or basins are drained, the drainage is generally carried out by directly plugging the downpipe into the floor drain. This method can cause the downpipe to fall out and the sewage to flow onto the ground when the drainage volume of the washing machine is large or the user accidentally kicks it. Therefore, some users use a method of installing a downpipe on the drainage pipe on the ground and sealing the downpipe with the downpipe to drain the water. However, this method cannot achieve ground drainage, resulting in the sewage on the ground being unable to be discharged. An additional floor drain needs to be set, which requires the pipeline to be rearranged, increasing the cost.

The movable part 51 is provided with a water diversion hole 511 connected to the upper chamber 212 and the lower chamber 223 to guide the water flow. The inner diameter of the water diversion hole 511 is smaller than the inner diameter of the lower chamber 223, and the inner diameter of the water diversion hole 511 gradually decreases from top to bottom, thereby increasing the pressure of the water flow on the movable part 51, so that when the first water inlet 211 is filled with water, the water flow can stably drive the movable part 51 to close the second water inlet 222.

[0039] The movable part 51 includes a partition tube 512 and a partition plate 513 disposed on the top of the partition tube 512.

A part of the partition tube 512 and the partition plate 513 are located in the inner cavity of the main body head 21, and the other part of the partition tube 512 passes through the through opening 23 and extends into the inner cavity of the water discharger 22. A water discharge seal ring 83 is provided in the inner cavity of the water discharger 22 and at the bottom of the second water inlet 222. The water discharge seal ring 83 is rubber-coated with the water discharger 22. When the water discharger 3 is draining water, the bottom of the partition tube 512 is pressed on the water discharge seal ring 83 to form a seal.

[0041] The present invention also includes a floor drain seat 1, which is mounted outside the water discharge body 2 and is located outside the second water inlet 222. A water cavity 11 is formed between the water discharge body 2 and the floor drain seat 1, and the water cavity 11 is connected to the second water inlet 222. The floor drain seat 1 is provided with a floor outlet 12 connected to the water cavity 11.

[0042] The present invention also includes a hair interception net 4, which is arranged in the water passage chamber 11 and is used to intercept and collect hair. The hair interception net 4 is annular and includes a mounting ring 41 and a plurality of interception rods 42 arranged inside the mounting ring 41. The plurality of interception rods 42 are distributed at intervals along the circumference of the mounting ring 41, and one end of each interception rod 42 away from the mounting ring 41 is respectively close to the main body of the water and extends upward, and a hair collection groove 43 is formed between each interception rod 42 and the mounting ring 41. Specifically, as Fig. 9 As shown, the interception bar 42 is a concave arc structure. In other embodiments, the interception bar 42 is L-shaped.

[0043] The bottom end of the main body head 21 is provided with a plurality of support protrusions 213 spaced apart along its circumference, each support protrusion 213 is respectively placed in the floor drain port 12 of the floor drain seat 1, and the lower end of the drain portion 22 passes downward through the floor drain seat 1.

[0044] There are multiple second water inlets 222, which are distributed along the circumference of the water discharger 2. There are multiple first water inlets 211, which are distributed at intervals along the circumference of the water discharger 2. A rubber sealing cover 6 is connected to the first water inlet 211. Figure 1 , Fig.10 , Fig.11 As shown, after tearing off the thin layer 61 in the middle of the rubber sealing cover 6, the sewer pipe 3 can be inserted into the opening 62 of the rubber sealing cover 6, so that the sewer pipe 3 is connected to the first water inlet 211, and the opening 62 of the rubber sealing cover 6 will be tightly contracted on the sewer pipe 3 to form a sealing effect, and the rubber sealing cover 6 without tearing off the middle thin layer 61 can form a sealing effect by itself, so after the sewer body 2 is connected to the sewer pipe 3, the water flow will not overflow from the main body head 21. Specifically, the caliber size and number of the rubber sealing cover 6 and the first water inlet 211 can be designed according to user needs, and the redundant first water inlet 211 (the first water inlet 211 not connected to the sewer pipe 3) can be sealed with the rubber sealing cover 6 without tearing off the middle thin layer 61.

[0045] The drain port 221 of the main body 2 of the water discharger is rotatably connected with a flap 71, which flips downward to open the drain port 221 when draining water, and returns upward to close the drain port 221 when draining water. Specifically, the flap 71 is connected to the main body 2 of the water discharger through a return weight 72. Under the action of the return weight 72, the flap 71 ensures that the drain port 221 at the bottom of the main body 2 of the water discharger is in a closed state, which can prevent the odor and insects from the drain pipe 9 from escaping. During the drainage process, the flap 71 is opened under the action of water flow pressure / gravity, and returns to the normally closed state again after the water flow is drained.

[0046] The present invention also includes a multi-layer sealing ring 81, which is sleeved outside the water discharge body 2 and adapted to fit inside the drain pipe 9 connected to the lower end of the floor drain seat 1, and a sealing ring 82 is provided between the water discharge body 2, the floor drain seat 1 and the drain pipe 9. Specifically, a circle of limiting convex parts 224 for stopping the multi-layer sealing ring 81 is provided on the outer side of the water discharge part 22. The multi-layer sealing ring 81 can not only improve the sealing performance between the water discharge body and the drain pipe 9, but also increase the friction between the two, so as to ensure that the water discharge body 2 is stably fixed in the drain pipe 9.

[0047] A floor drain device of the present invention, such as Figure 4 As shown, when the downpipe 3 is not draining water, the first water inlet 211 does not flow in, and the movable member 51 is lifted up by the spring 52. At this time, the second water inlet 222 is in an open state, and the ground water can enter the downpipe body 2 normally. Figure 5As shown, when the sewer pipe 3 is draining, water enters the first water inlet 211, and the movable member 51 is pushed by the water flow to overcome the elastic force of the spring 52 and move downward, and presses on the sewer seal ring 83. At this time, the second water inlet 222 is closed, and the ground water cannot enter the sewer body 2. Since the drainage time of the sewer pipe 3 is short and the flow rate is large, the water in this part is discharged first, and by closing the second water inlet 222, the path for the water to overflow back to the ground is directly blocked.

[0048] A floor drain device of the present invention can realize two-way drainage. One way is from the sewer pipe 3 through the first water inlet 211 to the sewer main body 2, and then discharged through the drain port 221. The other way is from the ground through the ground drain port 12 into the water cavity 11, and through the second water inlet 222 to the sewer main body 2, and then discharged through the drain port 221. Therefore, the present invention can realize two drainage methods: sewer pipe drainage and ground drainage. In addition, the present invention sets an anti-backflow component in the sewer main body 2 to separate the sewer pipe drainage and the ground drainage, which can directly block the passage between the sewer main body 2 and the ground, prevent water from overflowing back to the ground, and realize quick drainage at the same time.

[0049] The floor drain device of the present invention, the unrelated parts are the same as those in the prior art or can be implemented by using the prior art.
