Example one

Drainage devices such as pumps are often adopted in the drainage process in life for drainage, however, when the pumps are adopted for drainage, the noise is high, and high electric energy is consumed, so that the energy waste is caused. For this purpose, the present embodiment provides a drainage apparatus, as shown in fig. 1, the drainage apparatus includes a water bin 300, a first U-shaped pipe 100 and a second U-shaped pipe 200, wherein the first U-shaped pipe 100 includes a first pipe arm 101 and a second pipe arm 102 that are communicated with each other, the second U-shaped pipe 200 includes a third pipe arm 201 and a fourth pipe arm 202 that are communicated with each other, a first water inlet is provided at an end of the first pipe arm 101, a position of the first water inlet is provided at a bottom of a container to be drained, a first water outlet is provided at an end of the second pipe arm 102, the first water inlet is located below a liquid level of the container to be drained, the first water outlet is disposed in the water bin 300, a position of the liquid level in the water bin 300 higher than the position of the first water inlet, a connecting pipe is provided at one side of the water bin 300, the connecting pipe passes through the fourth pipe arm 202 and extends into the fourth pipe arm 202 to be communicated with the fourth pipe arm 202, a second water inlet is provided at an end of the third pipe arm 201, the position of the second water inlet is also close to the bottom of the container to be drained, the tail end of the fourth pipe arm 202 is provided with a second water outlet, the second water inlet is positioned below the liquid level of the container to be drained, the second water outlet is arranged in the water storage container, when the position of the liquid level of the container to be drained is higher than that of the connecting pipe, liquid flows into the fourth pipe arm 202 through the first water outlet and the connecting pipe and seals the second water outlet, the fourth pipe arm 202 is communicated with one end of the third pipe arm 201 to generate siphon force, and the liquid in the container to be drained is sucked into the fourth pipe arm 202 through the third pipe arm 201. The drainage device does not need to consume electric energy, saves energy, finishes the drainage process through the siphoning of the first U-shaped pipe 100 and the second U-shaped pipe 200, and is stable in the whole drainage process without noise.

Preferably, the diameter of the second U-shaped pipe 200 of the drainage device is 1.5 to 2 times that of the first U-shaped pipe 100. Illustratively, the diameter of the second U-shaped tube 200 may be set to be 1.5 times, 1.6 times, 1.7 times, 1.8 times, 1.9 times, 2 times, or the like, the diameter of the first U-shaped tube 100. Of course, in other embodiments, the diameter of the second U-shaped tube 200 may be set to be other multiples of the diameter of the first U-shaped tube 100, which is not limited in this embodiment.

In one embodiment, the water sump 300 may be a cylindrical structure, and the second pipe arms 102 of the first U-shaped pipes 100 extend into the water sump 300 from the top of the water sump 300. In other embodiments, the sump 300 may also have a cylinder structure with other structures, for example, a cylinder structure with a rectangular or square cross section may also be used, and this embodiment is not limited thereto.

Further, when the sump 300 has a cylindrical structure, the diameter of the sump 300 is set to be equal to the diameter of the second U-shaped tubes 200. Because the diameters of the water sump 300 and the second U-shaped pipe 200 are the same, the pipes with the same size can be selected for processing during processing, materials with other specifications do not need to be prepared for processing, and the manufacturing process of the whole drainage device is relatively simple.

Preferably, a first straight pipe 400 is arranged in the fourth pipe arm 202 of the drainage device, the top end and the bottom end of the first straight pipe 400 are both communicated with the fourth pipe arm 202, a connecting pipe passes through the side wall of the fourth pipe arm 202 in a sealing manner to be communicated with the first straight pipe 400, and the communication position of the connecting pipe and the first straight pipe 400 is arranged near the top end of the first straight pipe 400. Since the second water inlet and the second water outlet of the second U-shaped tube 200 can be sealed by liquid, and the second U-shaped tube 200 is in a closed state, the first straight tube 400 is arranged in the fourth tube arm 202, so that the liquid flowing out from the connecting tube can smoothly flow into the fourth tube arm 202 of the second U-shaped tube 200 along the first straight tube 400, and the flow of the liquid disturbs the air near the top end of the first straight tube 400, so that a large suction force is generated at the top end of the first straight tube 400, so that one end of the fourth tube arm 202, which is communicated with the third tube arm 201, generates a large suction force, the second water inlet on the third tube arm 201 starts sucking a large amount of liquid, and the drainage device starts to drain water in a large amount.

Further, the diameter of the connecting pipe is the same as that of the first straight pipe 400, so that the amount of liquid coming out of the water sump 300 can be completely filled in the first straight pipe 400. Further, the diameter of the first straight tube 400 is equal to the diameter of the first U-shaped tube 100, so that the liquid sucked from the first U-shaped tube 100 can just fill the first straight tube 400, and the flow rate of the liquid is high, thereby generating a large suction force at the top end of the first straight tube 400. When the diameter of the first straight pipe 400 is smaller than the diameter of the first U-shaped pipe 100, on the one hand, inflow of water to the first water inlet of the first U-shaped pipe 100 is suppressed, and the amount of water discharged by the drainage device is reduced, and on the other hand, when the diameter of the first straight pipe 400 is smaller than the diameter of the first U-shaped pipe 100, although the flow rate of the liquid in the first straight pipe 400 increases, the resistance due to the reduction of the diameter is greater than the suction force due to the increase of the flow rate of the liquid, and thus the siphon force generated as a whole is smaller than the siphon force generated when the diameter of the first straight pipe 400 is equal to the diameter of the first U-shaped pipe 100.

Preferably, the drainage device in this embodiment further includes a second straight pipe 500, the second straight pipe 500 is communicated with the second water outlet on the fourth pipe arm 202, and the diameter of the second straight pipe 500 is equal to the diameter of the first straight pipe 400. Before not setting up second straight tube 500, only when the liquid level in the water storage container does not have the second delivery port, just can make second U type pipe 200 be in sealed state, and through the setting of second straight tube 500, make the second delivery port on the fourth pipe arm 202 can be sealed fast to the liquid that enters into in the fourth pipe arm 202 through first straight tube 400, thereby make second U type pipe 200 be in sealed state, need not to wait for the position that the liquid level in the water storage container surpassed the second delivery port, second U type pipe 200 just can begin drainage work, make drainage device's response speed faster. Of course, in other embodiments, the diameter of the second straight tube 500 may be smaller than the diameter of the first straight tube 400, which is not limited by this embodiment.

The specific working process is as follows:

filling liquid into the first U-shaped pipe 100, filling a certain amount of liquid into the water bin 300, so that the height of the liquid level in the water bin 300 is higher than the position of the first water outlet of the first U-shaped pipe 100, then starting to suck the liquid in a container to be drained into the water bin 300 through the first U-shaped pipe 100, increasing the liquid level in the water bin 300, when the liquid level in the water bin 300 exceeds the position of the connecting pipe, allowing the liquid in the water bin 300 to flow into the first straight pipe 400, allowing the liquid in the first straight pipe 400 to flow into the second U-shaped pipe 200 under the action of gravity, after a certain amount of liquid is accumulated, blocking the second water outlet of the second U-shaped pipe 200, allowing the second U-shaped pipe 200 to be in a relatively sealed state, and generating a large suction force at the top end of the first straight pipe 400 due to the flow of the liquid in the first straight pipe 400, allowing the second water inlet of the second U-shaped pipe 200 to start to suck the liquid, gradually filling the liquid into the liquid storage container and starting to drain into the liquid storage container, and stopping the drainage process until the liquid level in the container to be drained is lower than the position of the second water inlet of the second U-shaped pipe 200.

Example two

The present embodiment provides a drainage device, as shown in fig. 2, which is different from the drainage device in the first embodiment in that: in the embodiment, the third pipe arm 201 of the drainage device is further provided with the vent hole 203, the setting position of the vent hole 203 is higher than the setting position of the connecting pipe, when the liquid level in the container to be drained is lower than the setting position of the vent hole 203, air enters the second U-shaped pipe 200 through the vent hole 203, the sealing state of the second U-shaped pipe 200 is damaged, the second U-shaped pipe 200 stops sucking water, at this time, the first U-shaped pipe 100 continues sucking water until the liquid level in the container to be drained is lower than the setting position of the connecting pipe, the first U-shaped pipe 100 stops sucking water, the whole drainage process stops, and when the liquid level in the container to be drained is higher than the setting position of the vent hole 203, the drainage device restarts drainage work. Through the setting of air vent 203, drainage device can realize the automatic of drainage process and open and stop, need not artificial intervention, and the drainage process is very simple, does not have extra electric energy or artificial consumption.

Preferably, the ventilation hole 203 is a kidney-shaped hole, and the length direction of the kidney-shaped hole is the same as the extending direction of the third pipe arm 201. Through setting up air vent 203 to waist type hole for in the air enters into second U type pipe 200 gradually, the sealed state in the second U type pipe 200 is slowly destroyed, and the process of absorbing water stops slowly, has further guaranteed the stationarity of drainage device drainage process.

The specific working process is as follows:

filling liquid into the first U-shaped pipe 100, filling a certain amount of liquid into the water bin 300, so that the height of the liquid level in the water bin 300 is higher than the position of the first water outlet of the first U-shaped pipe 100, then starting to suck the liquid in a container to be drained into the water bin 300 through the first U-shaped pipe 100, increasing the liquid level in the water bin 300, when the liquid level in the water bin 300 exceeds the position of the connecting pipe, allowing the liquid in the water bin 300 to flow into the first straight pipe 400, allowing the liquid in the first straight pipe 400 to flow into the second U-shaped pipe 200 under the action of gravity, after a certain amount of liquid is accumulated, blocking the second water outlet of the second U-shaped pipe 200, allowing the second U-shaped pipe 200 to be in a relatively sealed state, and generating a large suction force at the top end of the first straight pipe 400 due to the flow of the liquid in the first straight pipe 400, allowing the second water inlet of the second U-shaped pipe 200 to start to suck the liquid, gradually filling the liquid into the liquid storage container and starting to drain into the liquid storage container, when the liquid level in the container to be drained is lower than the position of the vent hole 203, air enters the second U-shaped pipe 200 through the vent hole 203, the sealing state in the second U-shaped pipe 200 is damaged, the suction force of the second water inlet of the second U-shaped pipe 200 is gradually reduced along with the increasing amount of air entering, no liquid is sucked into the second water inlet, at the moment, the first U-shaped pipe 100 continuously drains water into the sump 300, the liquid is drained into the second U-shaped pipe 200 through the first straight pipe 400 and flows out through the second water outlet, when the liquid level in the container to be drained continuously drops to a height lower than the height of the connecting pipe, the first U-shaped pipe 100 stops draining the liquid into the sump 300, and the draining process stops.

The rest of the structure of this embodiment is the same as that of the first embodiment, and is not described again.
