Description

Technical Field

[0001] This invention belongs to the technical field of condensate drain pipe unblocking, specifically relating to a mechanical unblocking and clearing device for air conditioner condensate drain pipes. Background Technology

[0002] During the cooling process, condensation will be generated on the surface of the heat exchanger of the indoor unit of the air conditioner. Usually, the water will be drained to the outside or the sewer through the condensate drain pipe. After long-term use, mold, dust and dirt will easily grow on the inner wall of the condensate drain pipe, and it may even become blocked due to the entry of foreign objects, which will prevent the condensate from draining normally. This will lead to problems such as water leakage from the indoor unit, ceiling saturation, and damp walls, which will seriously affect the safety of air conditioner use and the indoor environment.

[0003] Problems with existing technology:

[0004] 1. Most existing condensate drain cleaning tools are fixed-length cleaning brushes, which are difficult to adjust flexibly according to the actual pipe length. When the pipe is long, it is necessary to frequently extend the brush or change the tool, which is cumbersome and inefficient.

[0005] 2. Most of the brush heads in existing common drain cleaning devices are threaded or fixed with screws. When replacing them, tools such as wrenches are required. Moreover, the brush head specifications are limited and it is difficult to adapt to condensate pipes of different diameters. Forcing them to be used can easily cause the brush head to get stuck or the cleaning to be incomplete. Summary of the Invention

[0006] The purpose of this invention is to provide a mechanical unblocking and clearing device for air conditioner condensate pipes, which can solve the problems that existing condensate pipe unblocking tools are mostly fixed-length cleaning brushes, which are difficult to adjust flexibly according to the actual pipe length. When the pipe is long, it is necessary to frequently extend the brush or change the tool, which is cumbersome and inefficient.

[0007] The specific technical solution adopted by this invention is as follows:

[0008] A mechanical unblocking and clearing device for air conditioner condensate pipes includes a handheld telescopic component. The left end of the handheld telescopic component is fixedly connected to the right end of a mounting drive component. A cleaning brush head component is provided on the left end of the mounting drive component, and the cleaning brush head component is detachably connected to the mounting drive component.

[0009] The handheld telescopic assembly includes a hollow handheld grip. A small motor II is fixedly installed inside the right end of the hollow handheld grip. The output shaft of the small motor II is fixedly connected to the right end of a threaded rod. The threaded rod is threadedly connected to a columnar sliding block with a threaded hole inside. Four evenly distributed connecting rods III are fixedly connected to the left end of the columnar sliding block. The left ends of the four connecting rods III pass through four through holes opened inside the left end of the hollow handheld grip and are all fixedly connected to a circular mounting plate. The left end of the circular mounting plate is fixedly connected to the right end of the mounting drive assembly.

[0010] The mounting drive assembly includes a fixed sleeve, the right end of which is fixedly connected to a circular mounting plate. A small motor is fixedly mounted inside the left end of the fixed sleeve. The output shaft of the small motor passes through the left end of the fixed sleeve and is fixedly connected to the right end of the fixed shaft. The left end of the fixed shaft is fixedly connected to the mounting sleeve.

[0011] The mounting sleeve connects to the cleaning brush head assembly via a positioning slot inside its left end. The positioning slot has insertion plates on both its upper and lower sides. Both insertion plates are inserted into the cleaning brush head assembly. The relatively close ends of the two insertion plates pass through two square through slots inside the positioning slot and are fixedly connected to two mounting slide plates. Both mounting slide plates are slidably connected to a fixing rod via internal limiting holes. Fixing plates are fixedly connected to both the upper and lower ends of the fixing rod. Both fixing plates are fixedly connected to the left side of the mounting sleeve. Springs are sleeved on both the upper and lower sides of the fixing rod. The relatively far ends of the two springs are fixedly connected to the two fixing plates, and the relatively close ends of the two springs are fixedly connected to the two mounting slide plates. Both mounting slide plates... The hinge shaft at its right end is movably connected to one end of each of the two hinge plates. The other ends of the two hinge plates are movably connected to a push-pull plate with two hinge seats at its left end. The right end of the push-pull plate is fixedly connected to two connecting rods. The right ends of the two connecting rods pass through two through holes opened inside the right end of the mounting sleeve and are fixedly connected to a connecting slip ring. The connecting slip ring is movably connected to an annular connecting head with an annular groove opened inside. The right end of the annular connecting head is fixedly connected to two connecting rods. The right ends of the two connecting rods pass through two circular holes opened inside the left end of the fixed sleeve and are fixedly connected to an annular plate. The right end of the annular plate is fixedly connected to two synchronous electric push rod bodies. The right ends of the two synchronous electric push rod bodies are fixedly installed on the right side inside the fixed sleeve.

[0012] The handheld telescopic assembly also includes an anti-slip sleeve, which is fitted over the outside of the handheld hollow grip. The left end of the handheld hollow grip is movably connected to the left end of the threaded rod, and the inner wall of the handheld hollow grip is slidably connected to the columnar sliding block.

[0013] The cleaning brush head assembly includes a connecting block. The connecting block is connected to a mounting sleeve with a positioning slot on its left end via two positioning blocks on its right end. The two positioning blocks are connected to two connecting plates via slots inside them. The connecting block is fixedly connected to the right end of the brush head connecting rod. A water pipe brush head is provided at the left end of the brush head connecting rod.

[0014] The technical effects achieved by this invention are as follows:

[0015] 1. This invention, through its handheld telescopic component, allows for flexible adjustment of the overall working length according to the actual length of the condensate pipe. This eliminates the need for operators to frequently change tools or use ladders or other auxiliary equipment to unclog long-distance pipes. Simultaneously, the drive assembly rotates the cleaning brush head assembly, enabling active mechanical unclogging of the pipe's inner wall. Compared to traditional manual brushing methods, this significantly improves cleaning efficiency and effectiveness. Furthermore, the detachable connection between the cleaning brush head assembly and the drive assembly allows for quick replacement of the appropriate brush head based on the condensate pipe's inner diameter, greatly enhancing the device's versatility and flexibility in unclogging pipes of different specifications and reducing tool costs for various scenarios.

[0016] 2. This invention, through the insertion and engagement of the positioning slot and the plug-in plate, and with the help of a synchronous electric push-pull rod, hinge plate, spring and other linkage structures, allows the operator to control the separation or locking of the plug-in plate and the brush head assembly with one click. The disassembly and installation of the brush head can be completed without additional tools. This mechanical quick-change design avoids the problems of cumbersome disassembly and assembly and easy loss of parts in the traditional bolt fixing method. It is particularly suitable for on-site construction environments that require multiple replacements of brush heads of different sizes, significantly shortening the work preparation time and improving the efficiency of continuous dredging operations.

[0024] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0025] like Figure 1-5 As shown, a mechanical unblocking and clearing device for air conditioner condensate pipes includes a handheld telescopic component 3. The left end of the handheld telescopic component 3 is fixedly connected to the right end of the mounting drive component 2. A cleaning brush head component 1 is provided on the left end of the mounting drive component 2, and the cleaning brush head component 1 is detachably connected to the mounting drive component 2. The handheld telescopic component 3 allows the operator to easily hold the device for use. The handheld telescopic component 3 can also be adjusted to change the overall length of the device according to the length of the condensate pipe to be unblocked or cleaned. Then, with the cooperation of the mounting drive component 2 and the cleaning brush head component 1, the unblocking and cleaning process of condensate pipes of different lengths can be realized. The mounting drive component 2 can drive the cleaning brush head component 1 to rotate, thereby achieving the unblocking and cleaning of the condensate pipe. Furthermore, the mounting drive component 2 can also easily replace the appropriate cleaning brush head component 1 according to the different inner diameters of the condensate pipe to be unblocked or cleaned, increasing the flexibility of the device during use.

[0026] The handheld telescopic assembly 3 includes a hollow handheld grip 33. A small motor 37 is fixedly installed on the right end of the hollow handheld grip 33. The output shaft of the small motor 37 is fixedly connected to the right end of a threaded rod 34. The threaded rod 34 is threadedly connected to a cylindrical sliding block 35 with a threaded hole inside. Four evenly distributed connecting rods 32 are fixedly connected to the left end of the cylindrical sliding block 35. The left ends of the four connecting rods 32 pass through four through holes opened inside the left end of the hollow handheld grip 33 and are fixedly connected to a circular mounting plate 31. The left end of the circular mounting plate 31 is fixedly connected to the right end of the mounting drive assembly 2. During the use of the device, the rotation of the output shaft of the small motor 37 drives the threaded rod 34 to rotate. Then, with the cooperation of the connecting rods 32 and the hollow handheld grip 33, the cylindrical sliding block 35 can be moved to the left. Then, with the cooperation of the connecting rods 32 and the circular mounting plate 31, the overall length of the device can be adjusted, which is convenient for cleaning the inside of condensate pipes of different lengths.

[0027] The drive assembly 2 includes a fixed sleeve 214. The right end of the fixed sleeve 214 is fixedly connected to the circular mounting plate 31. A small motor 216 is fixedly installed inside the left end of the fixed sleeve 214. The output shaft of the small motor 216 passes through the left end of the fixed sleeve 214 and is fixedly connected to the right end of the fixed shaft 211. The left end of the fixed shaft 211 is fixedly connected to the mounting sleeve 21. The mounting sleeve 21 is connected to the cleaning brush head assembly 1 through a positioning slot 22 opened inside its left end. Through the cooperation of the positioning slot 22 and the plug plate 23, the right end of the cleaning brush head assembly 1 can be quickly installed and fixed inside the mounting sleeve 21. Then, the rotation of the output shaft of the small motor 216 drives the fixed shaft 211 to rotate, thereby driving the mounting sleeve 21 to rotate. The rotation of the mounting sleeve 21 drives the fixed cleaning brush head assembly 1 to rotate, thereby achieving the effect of unblocking and cleaning the inside of the condensate pipe.

[0028] Both the upper and lower sides of the positioning slot 22 are provided with insertion plates 23. Both insertion plates 23 are inserted into the cleaning brush head assembly 1. The relatively close ends of the two insertion plates 23 pass through two square through slots inside the positioning slot 22 and are respectively fixedly connected to two mounting slide plates 24. Both mounting slide plates 24 are slidably connected to the fixing rod 25 through limiting holes inside them. Fixing plates 26 are fixedly connected to both the upper and lower ends of the fixing rod 25. Both fixing plates 26 are fixedly connected to the left side of the inside of the mounting sleeve 21. Springs 27 are sleeved on both the upper and lower sides of the fixing rod 25. The relatively far ends of the two springs 27 are respectively fixedly connected to the two fixing plates 26. The relatively close ends are respectively fixedly connected to two mounting slide plates 24. Each mounting slide plate 24 is movably connected to one end of two hinge plates 28 via a hinge shaft at its right end. The other ends of both hinge plates 28 are movably connected to a push-pull plate 29 with two hinge seats at its left end. Two connecting rods 210 are fixedly connected to the right end of the push-pull plate 29. The right ends of the two connecting rods 210 pass through two through holes opened inside the right end of the mounting sleeve 21 and are fixedly connected to a connecting slip ring 212. The connecting slip ring 212 is movably connected to an annular connecting head 213 with an annular groove opened inside. Two connecting rods 215 are fixedly connected to the right end of the annular connecting head 213. The right end of the connecting rod 215 passes through two circular holes opened inside the left end of the fixed sleeve 214 and is fixedly connected to the annular plate 217. Two synchronous electric push rod bodies 218 are fixedly connected to the right end of the annular plate 217. The right ends of the two synchronous electric push rod bodies 218 are fixedly installed on the right side inside the fixed sleeve 214. The synchronous electric push rod bodies 218 drive the annular plate 217 to move to the left, which, in conjunction with the connecting rod 215, drives the annular connector 213 to move to the left. During the movement of the annular connector 213 to the left, the connecting slip ring 212, the fixed shaft 211, and the connecting rod 210 are connected... With the cooperation of the sliding plate 29, the push-pull plate 29 can be moved to the left inside the mounting sleeve 21. At this time, with the cooperation of the hinge plate 28, the two mounting slide plates 24 can overcome the elastic force of the spring 27 and move closer to each other, thereby pushing the two plug plates 23 out of the mounting slot so that they are no longer plugged into the cleaning brush head assembly 1. At this time, the cleaning brush head assembly 1 can be quickly disassembled by pulling it to the left. With the cooperation of the connecting slip ring 212, the annular connector 213, the connecting rod 210 and the connecting rod, the push-pull plate 29 can be easily moved to the left and right directions inside the mounting sleeve 21 without affecting the normal rotation of the mounting sleeve 21.

[0029] Furthermore, the handheld telescopic assembly 3 also includes an anti-slip sleeve 36, which is fitted over the outside of the handheld hollow grip 33. The left end of the handheld hollow grip 33 is movably connected to the left end of the threaded rod 34, and the inner wall of the handheld hollow grip 33 is slidably connected to the columnar sliding block 35. The anti-slip sleeve 36 and the handheld hollow grip 33 make it convenient for operators to hold the device for use.

[0030] Furthermore, the cleaning brush head assembly 1 includes a connecting block 13. The connecting block 13 is connected to the mounting sleeve 21 with a positioning slot 22 on its left end through two positioning blocks 14 on its right end. The two positioning blocks 14 are connected to two plug-in plates 23 through slots inside them. The connecting block 13 is fixedly connected to the right end of the brush head connecting rod 12. The left end of the brush head connecting rod 12 is provided with a water pipe brush head 11. The connection of the connecting block 13, positioning blocks 14, positioning slots 22 and plug-in plates 23 can quickly realize the disassembly and assembly of the brush head connecting rod 12 and the water pipe brush head 11. The rotation of the mounting sleeve 21, in conjunction with the plug-in plates 23, positioning blocks 14, connecting block 13 and brush head connecting rod 12, can drive the water pipe brush head 11 to rotate, thereby achieving the effect of unblocking and cleaning the inside of the condensate pipe.

[0031] The working principle of this invention is as follows:

[0032] When cleaning the inside of the condensate pipe, the operator holds the hollow handheld sleeve 33 with one hand and inserts the pre-installed pipe brush head 11 into the condensate pipe opening. Then, the small motor 216 is started, and its output shaft drives the mounting sleeve 21 and the cleaning brush head assembly 1 to rotate through the fixed shaft 211. This mechanically scrapes and peels off the dirt inside the pipe wall. At the same time, the operator maintains a slight forward push to gradually advance the pipe brush head 11 as it rotates. During the continuous cleaning operation, if the brush head has not yet reached the blocked section of the pipe or needs to go deeper into the distant pipe section, there is no need to stop rotating. The small motor 37 can be started directly. The output shaft of the small motor 37 drives the threaded rod 34 to rotate, driving the columnar sliding block 35 to move to the left. Through the connecting rod 32 and the circular mounting plate 31, the entire mounting drive assembly 2 and the brush head are pushed forward continuously, realizing continuous length adjustment of the device while it is not rotating, so as to adapt to different lengths of condensate pipes and ensure that the pipe brush head 11 can reach the deepest part of the pipe to complete the full section of cleaning.

[0033] During the cleaning process, when it is necessary to replace the appropriate water pipe brush head 11 according to the different inner diameters of the condensate pipe, the two synchronous electric push rod bodies 218 are extended by controlling the extension of the body, pushing the annular plate 217, connecting rod 215, annular connector 213 and connecting slip ring 212 to move to the left. The connecting rod 210 pushes the push-pull plate 29 to move to the left. The push-pull plate 29 drives the two mounting slide plates 24 to overcome the elastic force of the spring 27 and move closer to each other, so that the plug plate 23 is disengaged from the slot inside the positioning plug 14. At this time, the old cleaning brush head assembly 1 is pulled to the left and removed. The cleaning brush head assembly 1 of the appropriate specification is inserted into the positioning slot 22 of the mounting sleeve 21. The synchronous electric push rod body 218 is retracted by controlling the spring 27 to reset so that the plug plate 23 is automatically inserted to complete the locking of the replaced cleaning brush head assembly 1. At this time, the dredging operation of pipes with different diameters can be carried out.

[0034] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
