Description

Technical Field

[0001] The utility model relates to a connecting device for self-cleaning of pipelines, belonging to the field of fabric cleaning machines. Background Art

[0002] Fabric art refers to products made of fabric that have been artistically processed to achieve certain artistic effects to meet people's daily needs. Fabric art will accumulate a lot of dirt after long-term use, and fabric cleaning machines are usually used to clean fabric art products.

[0003] In the prior art, during the sewage recycling process of the fabric washing machine, impurities in the sewage will adhere to the inner wall of the sewage pipe, which will affect the use of the sewage pipe as the usage time increases. When cleaning the inner wall of the sewage pipe, some fabric washing machines will first remove the cleaning brush from the sewage pipe and connect the cleaning device as a whole to one end of the sewage pipe. Then, the clean water is transported to the clean water pipe through the water pump inside the fabric washing machine and sprayed out through the nozzle. The sprayed clean water will flow to the return port due to the obstruction of the obstruction to flush the inner wall of the sewage pipe. The cleaned sewage will flow into the dirty water tank along the sewage pipe, but the clean water flowing to the return port due to the obstruction of the obstruction is relatively scattered, and it is difficult to ensure that it can contact the inner wall of the sewage pipe, resulting in poor cleaning effect on the inner wall of the sewage pipe. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present utility model is to provide a connection device for self-cleaning of pipes, so as to solve the problem that the cleaning devices of some fabric washing machines proposed in the above background technology are blocked by the shielding part, and the clean water flowing to the return port is relatively scattered, making it difficult to ensure that it can contact the inner wall of the sewage pipe, resulting in poor cleaning effect on the inner wall of the sewage pipe.

[0005] In order to achieve the above-mentioned object, the utility model is realized through the following technical solution: a connection device for self-cleaning pipelines, comprising a sewage pipe, a fixing frame fixedly connected to the inner wall of the sewage pipe, a clean water pipe fixedly connected to the inner wall of the fixing frame, a cleaning component movably connected to the surface of the sewage pipe, and a water diversion component provided on the surface of the cleaning component;

[0006] The cleaning component includes a shell movably connected to the surface of the sewage pipe, a guide plate is fixedly connected to the inner wall of the shell, a water inlet pipe is fixedly connected to the inner wall of the guide plate, a water shield is fixedly connected to the top of the guide plate above the water inlet pipe, and a plurality of water distribution holes are opened at the top of the guide plate.

[0007] Furthermore, the water diversion assembly includes a plurality of air inlet holes opened on the shell surface, the shell surface is fixedly connected to guide rails at the upper and lower ends of the air inlet holes, a cover is slidably connected in the guide rail, and a clearance hole is opened on the cover surface.

[0008] Furthermore, the guide plate is in a truncated cone shape, and the water shield is in a semicircular shape.

[0009] Furthermore, a filter screen is fixedly connected to the inner wall of the air inlet hole, the number of the clearance holes is consistent with the number of the air inlet holes, and the size of the clearance holes is consistent with the size of the air inlet holes.

[0010] Furthermore, the surface of the sewage pipe is fixedly connected with an external thread, the inner wall of the shell is fixedly connected with an internal thread, and the shell and the sewage pipe are threadedly connected.

[0011] Furthermore, the outer diameter of the water inlet pipe is equal to the inner diameter of the clean water pipe, and the water inlet pipe and the clean water pipe are movably connected.

[0012] The beneficial effects of the utility model are as follows: when the inner wall of the sewage pipe needs to be cleaned, the shell is rotated to fix it to the surface of the sewage pipe and ensure that the water inlet pipe is completely inserted into the clean water pipe. Then, while ensuring that the shell is in a vertical state, the clean water is guided to the water distribution hole through the water pump, water inlet pipe, water shield and guide plate inside the main unit. The clean water will eventually pass through the water distribution hole and fall to the inner wall of the sewage pipe and fall into the dirty water tank inside the main unit along the inner wall of the sewage pipe, thus completing the cleaning of the sewage pipe.

[0013] Rotate the cover so that it rotates along the guide rail to expose the clearance hole. Cooperate with the vacuum pump inside the main unit to allow clean water to quickly slide down along the inner wall of the sewage pipe, thereby effectively improving the efficiency of cleaning the inner wall of the sewage pipe. When the cleaning component is idle, the cover can prevent external dust from entering the shell, which is beneficial to ensure the cleaning effect of the sewage pipe.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0020] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a connecting device for pipeline self-cleaning, including sewage pipe 1, fixedly connected with fixed frame 2 on the inner wall of sewage pipe 1, fixedly connected with clean water pipe 3 on the inner wall of fixed frame 2, cleaning assembly 4 is movably connected on the surface of sewage pipe 1, and water guide assembly 5 is arranged on the surface of cleaning assembly 4;

[0021] Cleaning assembly 4 includes shell 401 movably connected on the surface of sewage pipe 1, fixedly connected with guide plate 402 on the inner wall of shell 401, fixedly connected with water inlet pipe 403 on the inner wall of guide plate 402, fixedly connected with water baffle 404 on the top of guide plate 402 above water inlet pipe 403, and a plurality of water distribution holes 405 are formed on the top of guide plate 402.

[0022] When the inner wall of sewage pipe 1 needs to be cleaned, shell 401 is fixed to the surface of sewage pipe 1 by rotating, and ensure that water inlet pipe 403 is completely inserted into clean water pipe 3, then under the condition that shell 401 is in vertical state, clean water is guided to water distribution hole 405 by water pump (not shown in the figure) in the host, water inlet pipe 403, water baffle 404 and guide plate 402, and finally clean water will fall to the inner wall of sewage pipe 1 through water distribution hole 405 and fall into dirty water tank (not shown in the figure) in the host along the inner wall of sewage pipe 1, that is, the cleaning of sewage pipe 1 can be completed.

[0023] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: water guide assembly 5 includes a plurality of air inlets 501 formed on the surface of shell 401, and guide rail 502 is fixedly connected on the surface of shell 401 at the upper and lower ends of air inlet 501, cover 503 is slidably connected in guide rail 502, and let go of the hole 504 is formed on the surface of cover 503. Rotate cover 503 to make it rotate along guide rail 502 to expose let go of the hole 504, cooperate with suction pump (not shown in the figure) in the host, so that clean water quickly slides down along the inner wall of sewage pipe 1, thereby effectively improving the efficiency of cleaning the inner wall of sewage pipe 1, when cleaning assembly 4 is idle, dust and other external environment can be prevented from entering shell 401 by cover 503, thereby facilitating to ensure the cleaning effect of sewage pipe 1.

[0024] The guide plate 402 is truncated cone-shaped, and the water shield 404 is semicircular. The truncated cone-shaped guide plate 402 can guide the clean water intercepted by the water shield 404 to the plurality of water distribution holes 405 provided at the top of the guide plate 402, thereby facilitating the subsequent cleaning of the inner wall of the sewage pipe 1. The semicircular shape of the water shield 404 allows the clean water intercepted by it to slide along its inner wall to the top of the guide plate 402.

[0025] A filter 6 is fixedly connected to the inner wall of the air inlet 501. The number of the clearance holes 504 is consistent with the number of the air inlet holes 501, and the size of the clearance holes 504 is consistent with the size of the air inlet 501. The filter 6 connected to the inner wall of the air inlet 501 can prevent foreign matter from entering the housing 401 along with the air when the main unit uses the internal suction pump to extract air from the sewage pipe 1. This not only effectively prevents the sewage pipe 1 from being blocked by foreign matter, but also prevents foreign matter from mixing into the clean water, which is beneficial to ensuring the cleaning effect of the inner wall of the sewage pipe 1. The number of the clearance holes 504 is consistent with the number of the air inlet holes 501, ensuring that the air inlet holes 501 and the clearance holes 504 are in a one-to-one correspondence. When the clearance holes 504 are aligned with the air inlet 501, the size of the clearance holes 504 is consistent with the size of the air inlet 501, ensuring that the clearance holes 504 are fully exposed, thereby ensuring the suction effect of the suction pump inside the main unit on clean water.

[0026] The surface of the sewage pipe 1 is fixedly connected with an external thread, and the inner wall of the housing 401 is fixedly connected with an internal thread, and the housing 401 and the sewage pipe 1 are threadedly connected. Since the surface of the sewage pipe 1 is fixedly connected with an external thread and the inner wall of the housing 401 is fixedly connected with an internal thread, the housing 401 can be quickly fixed to the surface of the sewage pipe 1 by rotating the housing 401 after it is put on the surface of the sewage pipe 1, thereby facilitating the subsequent cleaning of the inner wall of the sewage pipe 1 by the cleaning component 4.

[0027] The outer diameter of the water inlet pipe 403 is equal to the inner diameter of the clean water pipe 3, and the water inlet pipe 403 and the clean water pipe 3 are movably connected. When the housing 401 is placed on the surface of the sewage pipe 1, the outer diameter of the water inlet pipe 403 is equal to the inner diameter of the clean water pipe 3, ensuring that the water inlet pipe 403 can be smoothly inserted into the clean water pipe 3, thereby facilitating the subsequent introduction of clean water into the cleaning component 4.

[0028] Specific implementation method: During the process of recycling sewage by the fabric washing machine, impurities in the sewage will adhere to the inner wall of the sewage pipe 1, which will affect the use of the sewage pipe 1 as the use time increases. When the sewage pipe 1 needs to be cleaned, rotate the cleaning brush (not shown in the figure) to remove it from the surface of the sewage pipe 1, then put the shell 401 on the surface of the sewage pipe 1 and ensure that the water inlet pipe 403 can be fully inserted into the clean water pipe 3, and then fix the cleaning component 4 to the surface of the sewage pipe 1 by rotating the shell 401. Next, ensure that the shell 401 is in a vertical state and start the water pump inside the main unit. The water pump will deliver clean water to the clean water pipe 1. The clean water in the pipe 3 will then enter the interior of the housing 401 through the water inlet pipe 403 connected to the clean water pipe 3. The clean water entering the housing 401 will contact the water shield 404 after being sprayed out of the water inlet pipe 403. Due to the dual effects of the blocking of the water shield 404 and gravity, the clean water will slide along the inner wall of the water shield 404 to the top of the guide plate 402. The guide plate 402 will guide the clean water that has fallen to its top to the several water distribution holes 405 opened at its top. The clean water will eventually pass through the water distribution holes 405 and fall to the inner wall of the sewage pipe 1 and fall into the dirty water tank inside the main unit along the inner wall of the sewage pipe 1, thereby completing the cleaning of the sewage pipe 1.

[0029] Since the sewage pipe 1 is long, the clean water relies solely on gravity to slide down the inner wall of the sewage pipe 1 to clean the inner wall of the sewage pipe 1, resulting in limited cleaning efficiency. At this time, the cover 503 is rotated to rotate along the guide rail 502. After the clearance hole 504 opened on the surface of the cover 503 is aligned with the air inlet hole 501 opened on the surface of the shell 401, the rotation of the cover 503 is stopped. Next, the air pump inside the main unit is started, and the air pump will exhaust the inside of the sewage pipe 1. In this process, the clean water will quickly slide down along the inner wall of the sewage pipe 1 under the action of the air pump, thereby effectively improving the efficiency of cleaning the inner wall of the sewage pipe 1. When the cleaning component 4 is idle, the cover 503 can prevent external dust and the like from entering the shell 401, which is conducive to ensuring the cleaning effect of the sewage pipe 1.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
