Description

Technical Field

[0001] This invention relates to the field of automotive air conditioning technology, and more particularly to an anti-clogging automotive air conditioning water pipe. Background Technology

[0002] When the existing air conditioner is turned on, air conditioning water will flow from the evaporator into the drain pipe and then flow out from the drain pipe. The outlet of the drain pipe is usually located at the bottom of the car.

[0003] Because the drain pipe is located at the bottom of the car, mud and water will enter the drain pipe when the car goes through muddy or wet roads, causing blockage. When the air conditioning water cannot drain, it will flow into the car, causing water accumulation inside the car. When the drain pipe is blocked, it needs to be disconnected from the evaporator box to drain the water, and then the blockage needs to be pushed out with high-pressure air. Because the space inside the car is small, the person's movements will be very limited when doing this. At the same time, when disassembling, a large amount of blocked water will flow into the car, causing the items inside the car to soak and mold.

[0004] The drain pipe connects the passenger compartment to the outside environment. If the vehicle is submerged in water, water from outside will flow back into the vehicle through the drain pipe. If the vehicle is a high-voltage electric vehicle, water entering the vehicle may even cause safety issues. At the same time, because the drain pipe is hollow, noise and odors from outside can also enter the vehicle through the drain pipe, and some dust will enter the evaporator and condenser through the drain pipe, causing dust accumulation and affecting the cooling and heating effects of the air conditioning.

[0005] When cleaning the evaporator and condenser, some cleaning agent needs to be injected into the evaporator through the drain pipe to achieve a thorough cleaning. Since the drain pipe is located at the bottom of the car, the vehicle usually needs to be raised before the cleaning agent can be injected, which makes cleaning the car air conditioner quite troublesome. Summary of the Invention

[0006] To overcome the drawbacks of drainage blockage causing water to enter the car interior, external water to backflow into the evaporator and car interior through the drain pipe, and noise and odors to enter the car interior through the drain pipe, this invention provides a blockage-proof car air conditioning water pipe.

[0007] The technical solution is as follows: A clog-resistant automotive air conditioning water pipe includes a vehicle body, an evaporator, a first rubber water pipe, a plastic water pipe, and a second rubber water pipe; the evaporator is fixedly connected to the vehicle body; the evaporator is connected to the first rubber water pipe; the lower part of the first rubber water pipe is connected to the plastic water pipe; the plastic water pipe has an inlet hole; the lower part of the plastic water pipe is connected to the second rubber water pipe; it also includes a first water-blocking block, a retaining block, a second water-blocking block, a baffle block, a sensor, a water-pushing assembly, and a water-blocking assembly; the first water-blocking block is fixedly connected to the middle of the plastic water pipe, and the first water-blocking block has a ball-blocking hole in the middle; a retaining block is slidably connected to the front and rear of the first water-blocking block; the two retaining blocks jointly support the second water-blocking block, the density of the second water-blocking block being less than that of water; a baffle block is fixedly connected to the upper part of the plastic water pipe; the baffle block has a retaining hole in the middle; a sensor is slidably connected to the right side of the baffle block; a water-pushing assembly for pushing away blockages is connected to the plastic water pipe; and a water-blocking assembly for temporarily storing water is connected to the plastic water pipe.

[0009] Preferably, the water-blocking assembly includes a second retaining ball block, a third water-blocking block, a connecting rope, and a fourth water-blocking block; the second retaining ball block is fixedly connected to the lower part of the plastic water pipe; the second retaining ball block has a water outlet hole, which is hemispherical; the third water-blocking block is placed in the middle of the second retaining ball block, and the density of the third water-blocking block is greater than that of water; the connecting rope is fixedly connected to the middle of the third water-blocking block; the fourth water-blocking block is fixedly connected to the upper end of the connecting rope, and the density of the fourth water-blocking block is less than that of water.

[0010] Preferably, the adjusting assembly includes a pusher plate, a ball-holding plate, a spring, a slider, a second fixing block, and a second cylinder; the second fixing block is fixedly connected to the lower part of the first fixing block; a second cylinder is fixedly connected to the upper and lower parts of the second fixing block, and the second cylinder is connected to the vehicle's air supply system; the pusher plate is fixedly connected to the telescopic part of the upper second cylinder; the ball-holding plate is fixedly connected to the telescopic part of the lower second cylinder, and the ball-holding plate is provided with a material-holding groove; at least one spring is fixedly connected to the plastic water pipe; and the slider is fixedly connected to the left end of at least one spring.

[0018] When external water flows back in, the fourth water-blocking block will block the ball-stopping hole, effectively preventing the backflow of external water; the baffle block will also block the second water-blocking block, so the water will not flow into the evaporator box. This prevents the air conditioning water from flowing back into the car when pushed. At the same time, since there is no space to flow upwards, the pushed water can only flow downwards, and the downward-flowing air conditioning water will squeeze the blockage, thereby achieving the effect of clearing the blockage and effectively preventing the drain pipe from becoming clogged.

[0019] This invention enables convenient injection of cleaning fluid, solving the problem of inconvenient injection. After injection, the fluid can be quickly discharged, greatly accelerating the cleaning speed. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0030] A type of clog-resistant car air conditioning water pipe, such as Figure 1-5 As shown, it includes a vehicle body 1, an evaporator 2, a first rubber water pipe 3, a plastic water pipe 4, and a second rubber water pipe 5; the vehicle body 1 is fixedly connected to the evaporator 2; the evaporator 2 is connected to the first rubber water pipe 3; the lower part of the first rubber water pipe 3 is connected to the plastic water pipe 4; the plastic water pipe 4 has a liquid inlet hole 4a; the lower part of the plastic water pipe 4 is connected to the second rubber water pipe 5.

[0031] It also includes a first water-blocking block 206, a clamping block 201, a second water-blocking block 202, a baffle block 203, a sensor 204, a water-pushing assembly, and a water-blocking assembly; the first water-blocking block 206 is fixedly connected to the middle of the plastic water pipe 4, and the first water-blocking block 206 has a ball-blocking hole 206a in the middle; a clamping block 201 is slidably connected to the front and rear sides of the upper part of the first water-blocking block 206; the two clamping blocks 201 jointly support the second water-blocking block 202, and the upper and lower parts of the clamping blocks 201 are both set in a frustum shape, so that the ball-blocking hole 206a is blocked by the descent of the clamping blocks 201 to prevent cleaning. The agent flows downwards. The density of the second water-blocking block 202 is less than that of water, so the second water-blocking block 202 can float up when a blockage occurs. A baffle block 203 is fixedly connected to the upper part of the plastic water pipe 4. A jamming hole 203a is opened in the middle of the baffle block 203. The second water-blocking block 202, which is pushed upward by the water, is blocked through the jamming hole 203a. At this time, the baffle block 203 and the second water-blocking block 202 will block the rising water together, thereby preventing water from flowing back into the vehicle. A sensor 204 is slidably connected to the baffle block 203. The plastic water pipe 4 is connected to the water-pushing assembly. The plastic water pipe 4 is connected to the water-blocking assembly.

[0032] like Figure 5As shown, the water-pushing assembly includes a first fixing block 211, a first cylinder 212, and a water-pushing block 213; the first fixing block 211 is fixedly connected to the right side of the plastic water pipe 4; the first cylinder 212 is fixedly connected to the first fixing block 211, and the first cylinder 212 is connected to the car's air supply system. When the first cylinder 212 needs to extend or retract, the car's air supply system will supply and draw air to it, so that the first cylinder 212 can realize the function of extension and retraction; the water-pushing block 213 is fixedly connected to the retracted part of the first cylinder 212. The water-pushing block 213 is made of rubber, which can prevent water leakage when pushing water. By pushing the water-pushing block 213 through the first cylinder 212, the blockage of air conditioning water is pushed down, and the blockage will be pushed away together; the first fixing block 211 is connected to an adjustment component.

[0033] The specific work steps are as follows:

[0034] When the second rubber water pipe 5 is blocked by mud or other objects, preventing the air conditioning water from draining properly, the flowing air conditioning water will slowly accumulate through the blocked second rubber water pipe 5. The water level will then gradually rise to the first water-blocking block 206 inside the plastic water pipe 4. As the air conditioning water accumulates, the water level will slowly rise to the position of the second water-blocking block 202. The second water-blocking block 202 will rise along with the water level, and some water will flow towards the pusher block 213. When the second water-blocking block 202 rises to the jamming hole 203a, it will first push the sensor 204, causing the sensor 204 to receive information that the drain outlet is blocked. Then, the car's air supply system will supply air to the first cylinder 212, causing the first cylinder 212 to push the pusher block 213 to the left. The movement of the pusher block 213 pushes the air conditioning water to the left as well. Because the second water-blocking block 202 tightly blocks the jamming hole 203a, the pushed water will only flow downwards. Figure 4 As shown, this configuration prevents air conditioning water from flowing back into the vehicle when pushed. The water pushed downwards will squeeze out the blockage, thus clearing the blockage and effectively preventing the drain pipe from becoming clogged. Example 2

[0035] Based on Example 1, such as Figure 6-7As shown, the water-blocking assembly includes a second retaining ball block 101, a third water-blocking block 102, a connecting rope 103, and a fourth water-blocking block 104; the lower part of the plastic water pipe 4 is fixed with the second retaining ball block 101; the second retaining ball block 101 has a water outlet hole 101a, which is hemispherical; the third water-blocking block 102 is placed in the middle of the second retaining ball block 101, the density of the third water-blocking block 102 is greater than the density of water, and the third water-blocking block 102 is spherical to facilitate blocking the water outlet hole 101a. When the water submerges the third water-blocking block 102... When the water level rises, the third water-blocking block 102 will block the water outlet 101a to prevent water from flowing out; a connecting rope 103 is fixedly connected to the middle of the upper side of the third water-blocking block 102; a fourth water-blocking block 104 is fixedly connected to the upper end of the connecting rope 103. The density of the fourth water-blocking block 104 is less than that of water. The fourth water-blocking block 104 is spherical, which makes it easy to block the lower part of the ball-blocking hole 206a. When the water level rises, the fourth water-blocking block 104 will also rise together. When the fourth water-blocking block 104 floats, it can pull the third water-blocking block 102 to float together, thereby discharging the water.

[0036] The specific work steps are as follows:

[0037] When the car's air conditioning starts working, the air conditioning water flows into the plastic water pipe 4 through the first rubber water pipe 3. At this time, the air conditioning water flows down through the first water-blocking block 206 until it flows into the second retaining block 101. The third water-blocking block 102 blocks the water outlet 101a. Since the water outlet 101a is blocked by the third water-blocking block 102, the air conditioning water will be retained in the lower part of the plastic water pipe 4 by the third water-blocking block 102. Since the density of the third water-blocking block 102 is greater than that of water, when the air conditioning water submerges the third water-blocking block 102, the third water-blocking block 102 will not float. This allows a large amount of air conditioning water to be trapped inside the plastic water pipe 4. The accumulated air conditioning water can effectively isolate noise and odors outside the car.

[0038] As the water level of the accumulated air conditioning water slowly rises, the fourth water-blocking block 104 will also rise along with the water level. As the fourth water-blocking block 104 rises, the connecting rope 103 will become taut. Once the connecting rope 103 is taut, the fourth water-blocking block 104, as the water level rises further, will pull the third water-blocking block 102 up as well. At this point, some of the accumulated air conditioning water will flow out through the drain hole 101a, as shown in the diagram. This not only provides isolation but also ensures the drainage of the air conditioning water. As the water level drops, the fourth water-blocking block 104 will also bring the third water-blocking block 102 down with it. When the third water-blocking block 102 returns to the position of the water outlet 101a, it will block the water outlet 101a again to ensure the accumulation of air conditioning water. It should be noted that the density of the third water-blocking block 102 is greater than that of water. When the fourth water-blocking block 104 pulls the third water-blocking block 102 upward, the buoyancy of the fourth water-blocking block 104 will cause the third water-blocking block 102 to rise together.

[0039] When a vehicle passes through a wading area, water from outside the second rubber water pipe 5 flows back into the plastic water pipe 4. The third water-blocking block 102 is then pushed up by the external water. As the external water flows in, the fourth water-blocking block 104 rises along with the backflowing water level. When the fourth water-blocking block 104 rises to the first water-blocking block 206, it gets stuck in the ball-blocking hole 206a, making the lower part of the first water-blocking block 206 a sealed state, as shown in the figure. At this time, external water can no longer flow back into the ball-blocking hole 206a of the fourth water-blocking block 104, which can effectively prevent the backflow of external water. Example 3

[0040] Based on Example 2, such as Figure 8 As shown, the adjustment assembly includes a pusher plate 311, a ball-holding plate 312, a spring 313, a slider 314, a second fixing block 315, and a second cylinder 316; the lower part of the first fixing block 211 is fixedly connected to the second fixing block 315; the upper and lower parts of the second fixing block 315 are each fixedly connected to a second cylinder 316, and the second cylinder 316 is connected to the vehicle's air supply system; the upper part of the second cylinder 316 is fixedly connected to the pusher plate 311; the lower part of the second cylinder 316 is fixedly connected to the ball-holding plate 312, and the ball-holding plate 312 is provided with a material-holding groove 312a, which holds the fourth water-blocking block 104; the plastic water pipe 4 is fixedly connected to two springs 313; the left ends of the two springs 313 are jointly fixedly connected to the slider 314.

[0041] The specific work steps are as follows:

[0042] When the evaporator 2 needs cleaning, the upper second cylinder 316 is engaged in extension and retraction via the automotive air supply system, thereby causing the pusher plate 311 to retract. At this time, the retraction of the pusher plate 311 removes the supporting force from the clamping block 201. Simultaneously, because the second water-blocking block 202 has a certain weight, the clamping block 201, supporting the second water-blocking block 202, will descend together. The downward movement of the second water-blocking block 202 will block the upper part of the ball-stopping hole 206a. Figure 8As shown in the diagram, the first cylinder 212 then drives the pusher block 213 to retract, causing the pusher block 213 to push the protrusion below the slider 314, thus moving the slider 314 to the left. The cleaning fluid is then poured into the plastic water pipe 4 through the inlet hole 4a, and then into the evaporator 2 through the first rubber water pipe 3, achieving a thorough cleaning of the evaporator 2. During the pouring of the cleaning fluid, the lower half of the second water-blocking block 202 is stuck in the ball-stopping hole 206a, preventing the cleaning fluid from flowing downwards. The cleaning fluid is injected... The high-pressure injected cleaning agent, upon reaching the second water-blocking block 202, causes the cleaning machine to press it downwards. Since the cleaning agent is only present around the upper part of the second water-blocking block 202, it will not float. After injection, the pusher block 213 moves the slider 314 to the left, pushing the cleaning agent upwards again and pressurizing it to enhance the cleaning effect. Once cleaning is complete, the upper second cylinder 316 pushes the pusher plate 311 to the left, removing the jamming block 20. 1. The first water-blocking block 202 is lifted up, and the second water-blocking block 202 is also lifted up by the material-blocking block 201. At this time, a gap will appear between the second water-blocking block 202 and the material-blocking block 203, and the cleaning agent will flow downward through the gap. When the cleaning agent flows downward, it will flow onto the second ball-blocking block 101. As the water level between the second ball-blocking block 101 and the first water-blocking block 206 rises, the fourth water-blocking block 104 will drive the third water-blocking block 102 to rise and no longer block the second ball-blocking block 101, allowing the water to drain out. A large amount of cleaning agent remains at the top, and the amount of cleaning agent flowing downwards is greater than the amount discharged. When the water level rises during the discharge of cleaning agent, the fourth water-blocking block 104 will rise and block the ball-blocking hole 206a. To ensure the cleaning agent continues to flow downwards, the lower second cylinder 316 is controlled to push the ball-blocking plate 312 to the left. When the fourth water-blocking block 104 rises, the ball-blocking plate 312 will block it, preventing it from blocking the ball-blocking hole 206a. Figure 8 In the state shown, the cleaning agent can be discharged downwards continuously, which can effectively increase the discharge speed of the cleaning agent. The material jamming groove 312a can jam the fourth water blocking block 104 in the middle of the ball jamming plate 312 to prevent the material jamming block 201 from moving randomly when the cleaning agent is flushed downwards. After the cleaning agent is discharged, the ball jamming plate 312 is controlled to move to the right and return to its original position.
