Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1 to 6, the present embodiment provides a drainage structure, which includes a drainage pipe 100, a closing plate 200, a connecting arm 300, and a counterweight 400.

The drain pipe 100 of this embodiment has an upper end and a lower end, and has an upper water inlet 110 and a lower water outlet 120, wherein the water inlet 110 is capable of communicating with the air conditioner for receiving the condensed water from the air conditioner, the water outlet 120 is capable of discharging the condensed water flowing from the water inlet 110, and the condensed water is finally discharged from the water outlet 120 to a drain port (not shown) of the drain pipe.

The closing plate 200 of the present embodiment is hinged to the drainage pipe 100 and is used for closing or opening the water outlet 120, specifically, a mounting frame 210 is provided at the bottom of the outer wall of the drainage pipe 100, one end of the closing plate 200 is hinged to the mounting frame 210, and the closing plate 200 is in a closed state and is connected to the water outlet 120 in a sealing manner.

The connecting arm 300 of this embodiment has one end connected to the end of the closing plate 200 that is hingedly attached to the mounting bracket 210 and the other end connected to the counterweight 400, and the connecting arm 300 is angled relative to the closing plate 200, preferably at an angle of 120-150, more preferably 135, to the closing plate 200 to facilitate the closing plate 200 remaining stable in the open position.

Because the connecting arm 300 and the closing plate 200 form an angle with each other, the gravity of the counterweight 400 acting on the connecting arm 300 can break up the downward pulling force on the connecting arm 300, and under the action of the lever principle, the closing plate 200 has upward pressure, so that the closing plate 200 can normally close the water outlet 120.

The above structure can be fully explained by physical principles, specifically, as shown in fig. 5 and 6, the distance between the center of gravity of the closing plate 200 and the hinge of the closing plate 200 in this embodiment is L1, the distance between the center of gravity of the counterweight 400 and the hinge of the closing plate 200 in this embodiment is L2, the gravity of the closing plate 200 is M1, the weight of the counterweight 400 is M2, it is necessary to ensure that M1 × L1 < M2 × L2 is sufficient to enable the closing plate 200 to be in a normally closed state, and it is also sufficient that (M1+ M3) × L1> M2 × L2 assuming that the gravity of the water body capable of opening the closing plate 200 is M3.

Preferably, in order to open the closing plate 200 to close the water outlet 120 after reaching a reasonable water pressure, the present embodiment further configures the counterweight and the closing plate 200 as M1 × L1 < M2 × L2 < 1.5(M1 × L1), that is, the gravity of the water body capable of opening the closing plate 200 is designed to be less than half of the gravity of the closing plate 200, so as to ensure that the water outlet 120 is opened under a reasonable water pressure, prevent excessive water accumulation in the water drainage pipe 100, or open the closing plate 200 under a very small amount of water pressure.

As can be seen from the above description, the drainage structure provided in this embodiment utilizes the gravity of the counterweight 400 and the lever principle to realize the normal closing of the closing plate 200, i.e., the first position 600 in fig. 4, so as to effectively prevent the entry of the odor, the toxic and harmful gases, etc. into the air conditioner; after a certain amount of water is in the drain pipe 100, the water outlet 120 can be automatically opened under the action of water pressure to discharge condensed water, i.e., the second position 700 in fig. 4, and the closing plate 200 can automatically adjust the opening and closing degree according to the flow rate and flow rate of the condensed water so that the condensed water can be rapidly discharged.

Referring to fig. 3 and 4, in particular, the connecting arm 300 of the present embodiment has a first end 310 and a second end 320 opposite to each other, wherein the first end 310 is connected to the closing plate 200, and the second end 320 is connected to a weight 400, preferably, the first end 310 of the present embodiment has a horizontal height higher than that of the second end 320, when the closing plate 200 is in the normally closed state, the weight 400 is located below the closing plate 200, and in the process from closing to opening of the closing plate 200, the distance L2 between the center of gravity of the weight 400 and the hinge of the closing plate 200 is gradually increased, so that the closing plate 200 is conveniently restored to the normally closed state; if the weight block 400 is located above the closing plate 200 when the closing plate 200 is in the normally closed state, the distance L1 between the center of gravity of the weight block 400 and the hinge of the closing plate 200 is gradually increased during the process of opening the closing plate 200 from the closed state, which is not favorable for the closing plate 200 to return to the normally closed state.

With reference to fig. 3 and 4, based on the above structure, in order to prevent the condensed water from overflowing during the drainage process, or prevent odor and toxic and harmful gases from diffusing at the drain opening, a water outlet box 500 is further installed between the drainage pipe 100 and the drain opening, the water outlet box 500 has a third end 511 (upper end in the figure) and a fourth end 521 (lower end in the figure) that are open, the third end 511 is connected with the drainage pipe 100, and the fourth end 521 is used for communicating with the drain opening; the closing plate 200 and the balancing weight 400 are both located in the outlet box 500 and can rotate in the outlet box 500.

Preferably, the third end 511 of the outlet box 500 of the present embodiment is connected to the drain pipe 100 in a sealing manner, and the fourth end 521 of the outlet box 500 is also connected to the drain port in a sealing manner, which may be implemented by a sealing gasket (not shown in the figure) or the like.

In order to ensure the connection stability between the water outlet box 500 and the water outlet pipe 100, the connection cover 130 is further connected to the outer wall of the water outlet pipe 100 in the present embodiment, and the connection cover 130 is preferably integrally connected to the water outlet pipe 100 to ensure the sealing performance; and the bottom of the connection cover 130 is provided with a connection part 111; the connection portion 111 is detachably connected to the third end 511.

Specifically, the connecting portion 111 of the present embodiment includes a first step disposed at the bottom of the connecting cover 130, the third end 511 of the present embodiment is provided with a second step adapted to the shape and size of the first step, and the first step and the second step are sleeved together, so that the structure is simple and the installation of the sealing structure is facilitated.

Specifically, the water outlet box 500 of the present embodiment includes a box body portion 510 and a tube body portion 520 connected to each other; the radial dimension of the body portion 520 is less than the radial dimension or width of the cartridge portion 510; the top of the box portion 510 is a third end 511, and the bottom of the tube portion 520 is a fourth end 521.

In addition, in order to facilitate the connection between the box body portion 510 and the tube body portion 520 and to facilitate the collection and discharge of water flow, the present embodiment is provided with a reduced diameter portion 512 at the lower portion of the box body portion 510, and the bottom of the reduced diameter portion 512 is connected to the tube body portion 520; the reduced diameter portion 512 has a radial dimension that gradually decreases in a direction closer to the body portion 520.
