DETAILED DESCRIPTION

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] Combined with Figure 1-6 As shown, this embodiment provides a drainage structure, including specific components such as a drainage pipe 100, a closing plate 200, a connecting arm 300 and a counterweight block 400.

[0034] The drain pipe 100 of this embodiment is open at both ends, and has a water inlet 110 at the upper end and a water outlet 120 at the lower end, wherein the water inlet 110 can be connected to the air conditioner to receive condensed water from the air conditioner, and the water outlet 120 is used to discharge the condensed water flowing in from the water inlet 110, and the condensed water is finally discharged into the drain outlet of the sewer pipe (not shown in the figure) through the water outlet 120.

[0035] The closing plate 200 of this embodiment is hingedly mounted on the drain pipe 100 and is used to close or open the water outlet 120. Specifically, a mounting frame 210 is provided at the bottom of the outer wall of the drain pipe 100, and one end of the closing plate 200 is hingedly mounted on the mounting frame 210. When the closing plate 200 is in a closed state, it is sealed and connected to the above-mentioned water outlet 120.

[0036] One end of the connecting arm 300 of the present embodiment is connected to one end of the closing plate 200 hinged on the mounting frame 210, and the other end is connected to the counterweight 400, and the connecting arm 300 and the closing plate 200 are at an angle to each other. The angle between the connecting arm 300 and the closing plate 200 is preferably 120°-150°, and more preferably 135°, so that the closing plate 200 can remain stable in the open state.

[0037] Since the connecting arm 300 and the closing plate 200 are at an angle to each other, the gravity of the counterweight 400 acting on the connecting arm 300 can decompose the downward pulling force on the connecting arm 300. Under the action of the lever principle, there is an upward pressure on the closing plate 200, so that the closing plate 200 can always close the above-mentioned water outlet 120.

[0038] The above structure can be fully explained by physical principles. Figure 5 and 6 As shown, the distance between the center of gravity of the closed plate 200 of this embodiment and the hinge of the closed plate 200 is L1, the distance between the center of gravity of the counterweight block 400 of this embodiment and the hinge of the closed plate 200 is L2, the gravity of the closed plate 200 is M1, and the weight of the counterweight block 400 is M2. It is necessary to ensure that M1×L1<M2×L2 so that the closed plate 200 can be in a normally closed state, and assuming that the gravity of the water body that can open the closed plate 200 is M3, it is also necessary to satisfy (M1+M3)×L1>M2×L2.

[0039] Preferably, in order to close the water outlet 120 by opening the closing plate 200 after reaching a reasonable water pressure, the present embodiment also constructs the counterweight and the closing plate 200 as M1×L1<M2×L2<1.5(M1×L1), that is, the gravity of the water body that can open the closing plate 200 is designed to be less than half of the gravity of the closing plate 200, thereby ensuring that the water outlet 120 is opened under a reasonable water pressure, preventing excessive water accumulation in the drain pipe 100, or opening the closing plate 200 under a very small amount of water pressure.

[0040] In combination with the above description, it can be seen that the drainage structure provided in this embodiment uses the gravity of the counterweight block 400 and the principle of leverage to achieve the normal closure of the closing plate 200, that is, Figure 4The first position 600 in the drain pipe can effectively prevent odor and toxic and harmful gases from entering the air conditioner; and when there is a certain amount of water in the drain pipe 100, the water outlet 120 can be automatically opened under the action of water pressure to complete the discharge of condensed water, that is, Figure 4 The second position 700 is set in the middle, and according to the flow rate and flow rate of the condensed water, the closing plate 200 can adjust the opening and closing degree by itself so that the condensed water can be discharged quickly.

[0041] Combined with Figure 3 and 4 As shown, specifically, the connecting arm 300 of the present embodiment has a first end 310 and a second end 320 relative to each other, wherein the first end 310 is connected to the closed plate 200, and the second end 320 is connected to the counterweight 400. Preferably, the horizontal height of the first end 310 of the present embodiment is higher than the horizontal height of the second end 320. With this design, when the closed plate 200 is in the normally closed state, the counterweight 400 is located below the closed plate 200. During the process from closing to opening of the closed plate 200, the distance L2 between the center of gravity of the counterweight 400 and the hinge of the closed plate 200 gradually increases, thereby facilitating the closed plate 200 to return to the normally closed state. If, when the closed plate 200 is in the normally closed state, the counterweight 400 is located above the closed plate 200, during the process from closing to opening of the closed plate 200, the distance L1 between the center of gravity of the counterweight 400 and the hinge of the closed plate 200 gradually increases, which is not conducive to the closed plate 200 returning to the normally closed state.

[0042] Combined with Figure 3 and 4 As shown, based on the above structure, in order to prevent the condensed water from overflowing during the drainage process, or the emission of odor and toxic and harmful gases from the drain outlet, the present embodiment also installs a water outlet box 500 between the drain pipe 100 and the drain outlet, and the water outlet box 500 has an open third end 511 (the upper end in the figure) and a fourth end 521 (the lower end in the figure), the third end 511 is connected to the drain pipe 100, and the fourth end 521 is used to connect to the drain outlet; the closing plate 200 and the counterweight block 400 are both located in the water outlet box 500 and can rotate in the water outlet box 500.

[0043] Preferably, the third end 511 of the water outlet box 500 of this embodiment is sealed to the drain pipe 100, and the fourth end 521 of the water outlet box 500 is also sealed to the drain outlet. The sealing method can be achieved by a sealing gasket (not shown in the figure) and other structures.

[0044] In order to ensure the connection stability between the water outlet box 500 and the drain pipe 100, the present embodiment further has a connection cover 130 connected to the outer wall of the drain pipe 100. The connection cover 130 is preferably integrally connected to the drain pipe 100 to ensure sealing; and a connection portion 111 is provided at the bottom of the connection cover 130; the connection portion 111 is detachably connected to the third end 511.

[0045] Specifically, the connecting portion 111 of this embodiment includes a first step arranged at the bottom of the connecting cover 130, and the third end 511 of this embodiment is provided with a second step adapted to the shape and size of the first step. The first step and the second step are socketed together, with a simple structure and convenient for the installation of the sealing structure.

[0046] Specifically, the water outlet box 500 of this embodiment includes a box body 510 and a tube body 520 connected to each other; the radial dimension of the tube body 520 is smaller than the radial dimension or width of the box body 510; the top of the box body 510 is the third end 511, and the bottom of the tube body 520 is the fourth end 521.

[0047] In order to facilitate the connection between the box body 510 and the tube body 520, and to facilitate the collection and discharge of water, a reduced diameter portion 512 is provided at the lower part of the box body 510 in this embodiment, and the bottom of the reduced diameter portion 512 is connected to the above-mentioned tube body 520; the radial dimension of the reduced diameter portion 512 gradually decreases in the direction approaching the tube body 520.

[0048] In addition, this embodiment also provides an air conditioner (not shown in the figure), which has the above-mentioned drainage structure, and the condensate outlet of the air conditioner is connected to the above-mentioned water inlet 110. The other structures and specific working principles of the air conditioner are common knowledge to technicians in this field and will not be elaborated in this embodiment.
