DETAILED DESCRIPTION

[0041] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0042] Example 1

[0043] like Figure 1-2 As shown, this embodiment provides a sealed floor drain, including: a floor drain body A1a, a top cover 3a and a sealing ring 2, wherein the floor drain body A1a as a whole is in the shape of an inverted two-step step (for the convenience of distinction, it is divided into an upper step and a lower step in this embodiment), and its lower step extends into the sewer outlet, and the top cover 3a is installed on the top of the floor drain body A1a in a detachable manner (such as threading, snap-fitting, etc.), which is used to seal the top of the floor drain body A1a, and a first sealing ring 31a is provided at its bottom to enhance its sealing performance and prevent steam from leaking from the top when the equipment drains condensed water. A second sealing pad 12 is provided at the bottom of the upper step, and when in use, the second sealing pad 12 contacts the ground to prevent steam from leaking from the installation gap between the floor drain body A1a and the ground.

[0044] A plurality of first water inlets 11 are provided on the side wall of the upper step. The sealing ring 2 is sleeved on the upper step, and a sealing layer 23 is provided on its inner wall. A plurality of second water inlets 21 are provided at the same time. The shape and size of the second water inlets 21 are the same as those of the first water inlets 11. The interval between two adjacent first water inlets 11 is larger than the width of the second water inlet 21. When the second water inlets 21 and the first water inlet 11 are completely offset, the side wall of the upper step can form a closed structure. A handle 22 is provided on the outer wall of the sealing ring 2. The sealing ring 2 can be moved by the handle 22 to achieve alignment or offset of the second water inlet 21 with the first water inlet 11, thereby achieving switching between the closed and open states of the floor drain body A1a. Figure 3 As shown, when the sealing ring 2 is rotated to a state where the second water inlet 21 is aligned with the first water inlet 11, the water on the ground can be swept into the sewer from the opening of the second water inlet 21 and the first water inlet 11, thereby discharging the water on the ground.

[0045] The equipment straight pipe 4 penetrates into the floor drain body A1a from the side of the upper step, and the connection between it and the floor drain body A1a is sealed by the second sealing ring 41. The sealing ring 2 is provided with corresponding grooves to stagger the position of the equipment straight pipe 4 to ensure that the sealing ring 2 can move normally.

[0046] Specifically, Figure 4 As shown, when draining condensed water, the top cover 3a needs to be installed, and the sealing ring 2 is rotated to a state where the second water inlet 21 is misaligned with the first water inlet 11, so that the floor drain body A1a is completely sealed, and water and steam from the equipment straight pipe 4 enter the floor drain body A1a, and are blocked by the top cover 3a and the sealing ring 2, so that the steam can only be discharged from the sewer. Figure 5 As shown, when using the sink drain pipe 5 to drain water, the top cover 3a is removed, and then the sink drain pipe 5 is inserted into the floor drain body A1a to connect the sink drain pipe 5 with the sewer.

[0047] Example 2

[0048] like Figure 5-6 As shown, this embodiment provides a sealed floor drain, including: a floor drain body B1b, a plug plate 32b and a sealing ring 2. The floor drain body B1b is in the shape of an inverted three-step step (for easy distinction, it is divided into an upper step, a middle step and a lower step in this embodiment), the lower step extends into the sewer outlet, and a second sealing pad is provided at the bottom of the middle step to seal the contact portion between the middle step and the ground. A plurality of first water inlets 11 are provided on the side of the middle step. The sealing ring 2 adopts the same structure as in Example 1, and is installed at the middle step of the floor drain body B1b.

[0049] The upper step is a cavity for placing the plug plate 32b. A counterweight pipe 3b is provided in the upper step. The top of the counterweight pipe 3b extends into the upper step. The sink drain pipe 5 is inserted into the counterweight pipe 3b. A counterweight block 31b is provided at the bottom of the counterweight pipe 3b. The middle of the counterweight block 31b is a through hole connected to the counterweight pipe 3b. When the plug plate 32b is inserted, the counterweight block 31b presses the plug plate 32b so that the top of the floor drain body B1b is sealed. After the plug plate 32b is pulled out, the counterweight pipe 3b is connected to the sewer, and the sink drain pipe 5 can drain normally. A first sealing gasket 33b is provided on the bottom surface of the upper step cavity to improve the sealing performance of the plug plate 32b and the counterweight pipe 3b (when the plug plate 32b is pulled out).

[0050] like Figure 8 As shown, when draining the water on the ground, the sealing ring 2 is rotated until the second water inlet 21 is aligned with the first water inlet 11, and the water on the ground is swept into the sewer from the opening of the second water inlet 21 and the first water inlet 11.

[0051] like Fig. 9As shown, when draining condensed water, pull up the counterweight pipe 3b and the counterweight block 31b, insert the plug plate into the floor drain body, lower the counterweight pipe 3b and the counterweight block 31b, and use the counterweight block 31b to press the plug plate 32b to seal the top of the floor drain body B1b, and then rotate the sealing ring 2 to a state where the second water inlet 21 is misaligned with the first water inlet 11, so that the side of the floor drain body B1b is sealed, and water and steam from the equipment straight discharge pipe 4 enter the floor drain body B1b and are blocked by the plug plate 32b and the sealing ring 2, so that the steam can only be discharged from the sewer, thereby preventing steam from leaking into the workshop.

[0052] like Fig.10 As shown, when the sink drain pipe 5 is used for drainage, the plug plate 32b can be pulled out to achieve the connection between the sink drain pipe 5 and the sewer.

[0053] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
