Description

Technical Field

[0001] This application relates to the field of drainage pipe technology, and more specifically, to an air conditioning drainage pipe mechanism. Background Technology

[0002] An air conditioner drain pipe system is a specialized structure used to drain the condensate produced during air conditioner operation. It is compatible with different types of air conditioners, such as wall-mounted, cabinet, and central air conditioners. It can smoothly guide the condensate produced by the evaporator inside the air conditioner to the outside or a designated drainage location, preventing condensate leakage from damaging walls, furniture, or affecting the indoor environment. Some systems also have anti-clogging and anti-backflow functions. The length and direction of the pipe can be adjusted according to the installation scenario to ensure the long-term stable operation of the air conditioner, while reducing maintenance needs caused by condensate problems and improving the convenience and safety of air conditioner use.

[0003] In practice, during the drainage process, residual dust and impurities in the air conditioner drain pipe can easily accumulate and cause blockage. It is also difficult to achieve efficient drainage, prevent odor backflow, and prevent external water backflow at the same time. After the air conditioner stops running, odors can easily enter the room through the pipe, which brings inconvenience to the long-term stable use of the air conditioner drain pipe and the protection of the indoor environment. Utility Model Content

[0004] The purpose of this application is to provide an air conditioning drain pipe mechanism that solves the technical problems mentioned in the background art.

[0005] This application provides an air conditioner drain pipe mechanism, including a drain pipe, a connecting sleeve fixedly sleeved at the lower end of the drain pipe, a fixed pipe fixedly inserted into the lower part of the connecting sleeve, a spiral guide strip fixedly connected to the inner wall of the drain pipe, a fixed cover fixedly connected to the upper part of the fixed pipe, a water guide cover fixedly connected to one side of the lower end face of the fixed cover, an inclined water outlet opened on one side of the water guide cover, a fixed strip fixedly connected to the upper part of one side of the water guide cover, a flip plate provided below the fixed strip, and the outer wall of the flip plate fitting against the periphery of the water outlet.

[0006] Optionally, a water trap is fixedly connected to the lower end of the fixed pipe, and a drain head is fixedly sleeved at the other end of the water trap.

[0007] Optionally, a sealing cylinder is fixedly connected inside the fixed tube. The interior of the sealing cylinder is a frustum-shaped cavity, and the upper opening of the sealing cylinder is smaller than the lower opening.

[0008] Optionally, a float ball is provided below the sealing cylinder, and a water passage frame is fixedly connected to the lower part of the inside of the fixed pipe, with the float ball located above the water passage frame.

[0009] Optionally, a through-hole is provided on one side of the lower interior of the fixed cover, and the water guide cover is connected to the through-hole.

[0010] Optionally, a rotating shaft is rotatably connected between the fixing strip and the flip plate.

[0011] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0012] The spiral guide strip on the inner wall of the air conditioner drain pipe in this application guides the water flow to form a rotating vortex, dispersing residual dust and impurities, preventing sludge buildup and ensuring smooth drainage. Water flows through the connecting sleeve into the fixed pipe. The fixed cover and the water guide cover guide the water flow to accumulate pressure, pushing the flip plate to rotate around the shaft and open the outlet. The water flows through the sealing cylinder and the water guide frame in sequence into the water trap. A water seal is formed inside the trap to enhance the anti-backflow effect, and finally, the water is discharged from the drain head, completing efficient drainage.

[0013] When external water flows back from the drain head into the trap, the rising water level causes the float above the water guide to rise and fit against the lower opening of the sealing cylinder, forming a seal and effectively preventing water from continuing to rise and enter the drain pipe, thus preventing backflow. After the air conditioner stops operating, the tilting plate returns to its original position under its own weight, preventing odors from flowing back in. The entire device consistently balances unobstructed drainage with prevention of odors and backflow, greatly enhancing its practicality. Attached Figure Description

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-3This application provides an air conditioner drain pipe mechanism, including a drain pipe 1, a connecting sleeve 2 fixedly sleeved at the lower end of the drain pipe 1, a fixed pipe 3 fixedly inserted into the lower part of the connecting sleeve 2, and a spiral guide strip 6 fixedly connected to the inner wall of the drain pipe 1. The spiral guide strip 6 can guide the water flow to form a rotating vortex, disperse residual dust and impurities, avoid siltation and blockage, and ensure smooth drainage.

[0020] A fixed cover 10 is fixedly connected to the upper part of the inside of the fixed pipe 3. A water guide cover 11 is fixedly connected to one side of the lower end face of the fixed cover 10. An inclined water outlet 12 is opened on one side of the water guide cover 11. A fixed strip 14 is fixedly connected to the upper part of one side of the water guide cover 11. A flip plate 16 is provided below the fixed strip 14. The outer wall of the flip plate 16 fits against the outer periphery of the water outlet 12. A through-hole 13 is opened on one side of the lower part of the inside of the fixed cover 10, and the water guide cover 11 is connected to the through-hole 13. A rotating shaft 15 is rotatably connected between the fixed strip 14 and the flip plate 16. A water trap 4 is fixedly connected to the lower end of the fixed pipe 3. A sleeve is fixedly connected to the other end of the water trap 4. A sealing cylinder 7 is fixedly connected inside the drain head 5 and the fixed pipe 3. The interior of the sealing cylinder 7 is a frustum-shaped cavity, and the upper opening of the sealing cylinder 7 is smaller than the lower opening. A float ball 8 is provided below the sealing cylinder 7. A water passage frame 9 is fixedly connected inside the fixed pipe 3, and the float ball 8 is located above the water passage frame 9. Water flows through the connecting sleeve 2 into the fixed pipe 3. The fixed cover 10 and the water guide cover 11 guide the water flow to accumulate and generate pressure, which pushes the flip plate 16 to rotate around the rotating shaft 15 and open the water outlet 12. The water flows through the sealing cylinder 7 and the water passage frame 9 in sequence and enters the water trap 4. A water seal is formed in the trap to enhance the anti-odor effect. Finally, the water is discharged from the drain head 5, completing the efficient drainage.

[0021] When external water flows back from drain head 5 into water trap 4, the water level rises, causing the float ball 8 above the water flow rack 9 to rise and fit against the lower opening of the sealing cylinder 7 to form a seal, effectively preventing the water from continuing to rise and enter the drain pipe 1, thus preventing backflow. After the air conditioner stops operating, the flip plate 16 returns to its original position due to its own weight, fitting against the water outlet 12 to prevent odors from flowing back in. The entire device always balances smooth drainage with the effects of preventing odors and backflow.

[0022] Working principle: The condensate produced by the air conditioner first flows into the drain pipe 1. The spiral guide strip 6 on the inner wall of the drain pipe 1 guides the water flow downward along the spiral path, forming a rotating vortex. The impact force of the vortex can disperse the dust and impurities remaining in the drain pipe 1, preventing stagnation and blockage. The water flows to the connecting sleeve 2 at the lower end of the drain pipe 1, and then enters the fixed pipe 3 through the connecting sleeve 2.

[0023] The water first enters the fixed cover 10 inside the fixed pipe 3. The fixed cover 10 guides the water through the connecting port 13 into the water guide cover 11. The water accumulates in the water guide cover 11 and generates pressure, which pushes the flip plate 16 to rotate around the pivot 15 between the fixed strip 14 and the flip plate 16, causing the flip plate 16 to separate from the inclined outlet 12 on one side of the water guide cover 11. The water flows through the outlet 12 into the bottom of the fixed pipe 3. The water then passes through the sealing cylinder 7 and the water frame 9 in sequence and flows into the water trap 4. The water entering the water trap 4 will form a water seal in the trap, which enhances the anti-odor effect. Then the water flows out from the drain head 5 at the other end of the water trap 4, completing the basic drainage process.

[0024] When external water flows into the water trap 4 through the drain head 5, the water level at the other end of the water trap 4 rises and enters the fixed pipe 3. The float ball 8 above the water flow frame 9 gradually rises under the action of buoyancy. As the water level rises, the float ball 8 rises to fit with the lower opening of the sealing cylinder 7. At this time, the float ball 8 and the sealing cylinder 7 cooperate to form a sealing structure, which can effectively block the water flow from continuing to rise into the drain pipe 1 and prevent backflow.

[0025] When the air conditioner stops operating and condensate is no longer produced, the flip plate 16 resets under its own weight, re-attaching to the outside of the outlet 12 to prevent odors from flowing back in from the outlet 12, ensuring the overall drainage is airtight. The water level in the fixed pipe 3 gradually decreases, and the float ball 8 resets as the water level drops, returning to above the water guide 9. At this time, the water seal remaining in the trap 4 can still maintain the anti-backflow effect for a period of time until the water seal evaporates naturally or is replenished during the next drainage. The entire drain pipe 1 mechanism always maintains the dual functions of unobstructed drainage and anti-backflow.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
