Description

Technical Field

[0001] This utility model relates to the technical field of pipe unblocking, and in particular to a pipe unblocking device. Background Technology

[0002] As modern families increasingly demand higher quality of life, pipe blockage has become a growing concern. Pipe unclogging tools, as efficient, convenient, and safe tools, have a promising market prospect.

[0003] For example, the existing technology authorization announcement number CN207003578U discloses a one-shot venting pipe cleaner, which relates to the field of pipe cleaners. The other end of the air tank is provided with an air tank cover. One end of the air pumping pipe passes through the air tank cover and is set inside the air tank. The other end of the air pumping pipe is provided with a handle. The middle of the air tank cover is provided with an exhaust rod hole. An exhaust rod is inserted into the exhaust rod hole. A spring is sleeved on the exhaust rod. One end of the exhaust rod is provided with a rubber piston. The other end of the exhaust rod is fixedly connected to an exhaust pawl. The exhaust pawl is installed on the air pumping pipe.

[0004] However, during the use of this drain cleaner, it was found that the connection and disassembly between the air tank and the air pump hose was not convenient, and the air pumping efficiency was low, which reduced the effectiveness and convenience of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pipe cleaner that improves inflation efficiency, enhances connection sealing, improves loading and unloading convenience, enables rapid pipe unblocking, and improves operational convenience.

[0006] This utility model discloses a pipe dredging device, comprising a shell, a connecting part, and a storage cylinder. The connecting part is installed on the outer wall of the shell, and the storage cylinder is screwed onto the connecting part, with the storage cylinder communicating with the interior of the connecting part. It also includes an inflation device, a control device, a T-shaped piston, and an exhaust pipe. The T-shaped piston is slidably installed inside the connecting part, and the exhaust pipe is connected to the interior of the storage cylinder. The air inlet end of the exhaust pipe is positioned opposite to the T-shaped piston. The inflation device is located inside the shell and is used to efficiently inflate the storage cylinder. The control device is located on the shell and is used to control the exhaust from the storage cylinder. By operating the inflation device, the storage cylinder is rapidly inflated, improving inflation efficiency. When air is delivered to the storage cylinder through the connecting part and compressed, the air pushes the T-shaped piston to slide and block the air inlet end of the exhaust pipe. After the storage cylinder is fully pressurized, the control device vents air from the connecting part. Because the pressure inside the storage cylinder is greater than the pressure inside the connecting part, the pressure inside the storage cylinder pushes the T-shaped piston to slide back to its original position and open the air inlet end of the exhaust pipe, allowing the compressed gas inside the storage cylinder to be instantly discharged through the exhaust port of the exhaust pipe, thus dredging the pipe and improving operational convenience.

[0007] Preferably, the inflation device includes an air cylinder, a one-way valve, an external threaded pipe, a double-oil-sealed piston, a first connecting rod, and a handle. The air cylinder is installed on the inner wall of the housing. The one-way valve is connected to the exhaust end of the air cylinder, and the external threaded pipe is connected to the outer wall of the connecting part. The front end of the one-way valve is screwed onto the external threaded pipe and communicates with the inside of the connecting part. The first connecting rod is slidably installed inside the air cylinder. The double-oil-sealed piston is located at the end of the first connecting rod, and the handle is installed at the other end of the first connecting rod. By grasping the handle, the first connecting rod is moved back and forth, causing the first connecting rod to squeeze and discharge the air in the air cylinder through the double-oil-sealed piston. The discharged air enters the inside of the connecting part through the external threaded pipe and the one-way valve, thereby compressing and storing the air in the storage cylinder. By setting the one-way valve, the backflow of compressed air in the storage cylinder is effectively reduced, improving the long-term pressure holding effect in the storage cylinder. By setting the double-oil-sealed piston, the effect of squeezing and discharging air in the air cylinder is improved, the inflation efficiency in the storage cylinder is improved, and the labor intensity is reduced. By setting the one-way valve, the sealing firmness of the connection between the one-way valve and the connecting part is improved, while also improving the convenience of loading and unloading.

[0008] Preferably, the control device includes a first assembly, a pressing member, a second assembly, a second connecting rod, a sealing cap, and a through hole. Both the first and second assemblies are mounted on the inner wall of the housing. The pressing member is slidably mounted on the first assembly by a first spring providing pushing force, and the second connecting rod is slidably mounted on the second assembly by a second spring providing pushing force. The pressing member contacts the second connecting rod. The sealing cap is mounted on the end of the second connecting rod and is pressed tightly against the second assembly. The through hole is located on the connecting part, and the sealing cap seals the through hole. By pressing the pressing member, the end of the pressing member pushes the second connecting rod to move, causing the second connecting rod to move the sealing cap, thereby separating the sealing cap from the second assembly. Simultaneously, the sealing cap opens the through hole, thus releasing pressure in the connecting part. After the pressure in the connecting part decreases, the pressure in the storage cylinder pushes the T-shaped piston to reset and slide, opening the exhaust pipe, thereby facilitating the discharge of air from the storage cylinder and improving operational convenience.

[0009] Preferably, it also includes a connecting pipe and circular rubber plates. The connecting pipe is installed at the bottom of the storage cylinder and is connected to the exhaust pipe. Multiple sets of circular rubber plates are installed on the outer wall of the connecting pipe, and the diameter of the multiple sets of circular rubber plates decreases from top to bottom. By setting multiple sets of circular rubber plates, the sealing effect between pipes with different inner diameters and the connecting pipe is improved, and the pipe unblocking effect is improved.

[0010] Preferably, it also includes a pressure gauge, which is installed on the outer wall of the housing and communicates with the inside of the storage cylinder; by setting up the pressure gauge, the convenience of pressure measurement inside the storage cylinder is improved.

[0011] Preferably, the maximum inner diameter of the storage cylinder is 9cm; this increases the gas capacity of the storage cylinder and improves the pipe unblocking effect.

[0012] Preferably, the air cylinder is an extended design to improve the efficiency of filling the storage cylinder with air.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by operating the inflation device to quickly inflate the storage cylinder, the inflation efficiency is improved. When air is delivered to the storage cylinder through the connecting part and compressed and stored, the air pushes the T-shaped piston to slide and block the air inlet end of the exhaust pipe. After the storage cylinder is pressurized, the control device exhausts the air in the connecting part. Since the pressure in the storage cylinder is greater than the pressure in the connecting part, the pressure in the storage cylinder pushes the T-shaped piston to slide and reset and open the air inlet end of the exhaust pipe, so that the compressed gas in the storage cylinder is instantly discharged through the exhaust port of the exhaust pipe, thereby clearing the pipeline and improving the convenience of operation.

[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0023] like Figures 1 to 7 As shown, this utility model discloses a pipe cleaner, including a housing 1, a connecting part 2, and a storage cylinder 3. The connecting part 2 is installed on the outer wall of the housing 1, and the storage cylinder 3 is screwed onto the connecting part 2 and communicates with the inside of the connecting part 2. It also includes an inflation device, a control device, a T-shaped piston 4, and an exhaust pipe 5. The T-shaped piston 4 is slidably installed inside the connecting part 2, and the exhaust pipe 5 is connected to the inside of the storage cylinder 3. The air inlet end of the exhaust pipe 5 is positioned opposite to the T-shaped piston 4. The inflation device is installed inside the housing 1 and is used to efficiently inflate the storage cylinder 3. The control device is installed on the housing 1 and is used to control the exhaust of air from the storage cylinder 3.

[0024] like Figure 5 As shown, the inflation device includes an air cylinder 6, a one-way valve 7, an external threaded pipe 8, a double oil-sealed piston 9, a first connecting rod 10, and a handle 19. The air cylinder 6 is installed on the inner wall of the housing 1. The one-way valve 7 is connected to the exhaust end of the air cylinder 6. The external threaded pipe 8 is connected to the outer wall of the connecting part 2. The front end of the one-way valve 7 is screwed onto the external threaded pipe 8 and communicates with the inside of the connecting part 2. The first connecting rod 10 is slidably installed inside the air cylinder 6. The double oil-sealed piston 9 is located at the end of the first connecting rod 10. The handle 19 is installed at the other end of the first connecting rod 10.

[0025] In this embodiment, the inflation device is used to quickly inflate the storage cylinder 3, thereby improving inflation efficiency. When air is delivered to the storage cylinder 3 through the connecting part 2 and compressed, the air pushes the T-shaped piston 4 to slide and block the air inlet of the exhaust pipe 5. After the storage cylinder 3 is fully pressurized, the control device vents the air from the connecting part 2. Since the pressure inside the storage cylinder 3 is greater than the pressure inside the connecting part 2, the pressure inside the storage cylinder 3 pushes the T-shaped piston 4 to slide back to its original position and open the air inlet of the exhaust pipe 5. This allows the compressed gas inside the storage cylinder 3 to be instantly discharged through the exhaust port of the exhaust pipe 5, thus clearing the pipe and improving operational convenience. Example 2

[0026] Based on Example 1, such as Figure 7As shown, this utility model discloses a pipe unclogging device. The control device includes a first assembly 11, a pressing member 12, a second assembly 13, a second connecting rod 14, a sealing cap 15, and a through hole 16. The first assembly 11 and the second assembly 13 are both installed on the inner side wall of the housing 1. The pressing member 12 is slidably installed on the first assembly 11 by a pushing force provided by a first spring. The second connecting rod 14 is slidably installed on the second assembly 13 by a pushing force provided by a second spring. The pressing member 12 is in contact with the second connecting rod 14. The sealing cap 15 is installed at the end of the second connecting rod 14 and is pressed tightly against the second assembly 13. The through hole 16 is provided on the connecting part 2, and the sealing cap 15 seals the through hole 16.

[0027] like Figure 1 As shown, it also includes a connecting pipe 17 and a circular rubber plate 18. The connecting pipe 17 is installed at the bottom of the storage cylinder 3 and is connected to the exhaust pipe 5. Multiple sets of circular rubber plates 18 are installed on the outer wall of the connecting pipe 17, and the diameter of the multiple sets of circular rubber plates 18 decreases from top to bottom.

[0028] like Figure 1 As shown, it also includes a pressure gauge 20, which is installed on the outer wall of the housing 1 and communicates with the inside of the storage cylinder 3;

[0029] like Figure 3 As shown, the maximum inner diameter of the storage cylinder 3 is 9 cm;

[0030] like Figure 3 As shown, the air cylinder 6 is an extended design;

[0031] In this embodiment, the first connecting rod 10 is moved back and forth by gripping the handle 19, causing the first connecting rod 10 to compress and discharge the air in the air cylinder 6 through the double oil-sealed piston 9. The discharged air enters the connecting part 2 through the external threaded pipe 8 and the one-way valve 7, thereby compressing and storing the air in the storage cylinder 3. By setting the one-way valve 7, the backflow of compressed air in the storage cylinder 3 is effectively reduced, improving the long-term pressure holding effect in the storage cylinder 3. By setting the double oil-sealed piston 9, the effect of compressing and discharging the air in the air cylinder 6 is improved, the pressurization efficiency in the storage cylinder 3 is improved, and the labor intensity is reduced. A one-way valve 7 is installed to improve the sealing strength of the connection between the one-way valve 7 and the connecting part 2, and at the same time improve the convenience of loading and unloading. By pressing the pressing member 12, the end of the pressing member 12 pushes the second connecting rod 14 to move, so that the second connecting rod 14 drives the sealing cap 15 to move, thereby separating the sealing cap 15 from the second kit 13. At the same time, the sealing cap 15 opens the through hole 16, thereby relieving the pressure in the connecting part 2. After the pressure in the connecting part 2 is reduced, the pressure in the storage cylinder 3 pushes the T-shaped piston 4 to reset and slide and open the exhaust pipe 5, thereby facilitating the discharge of air in the storage cylinder 3 and improving the convenience of operation.

[0032] This utility model discloses a pipe unclogging device. During operation, the storage cylinder 3 is rapidly inflated by operating the inflation device. When the air is delivered to the storage cylinder 3 through the connecting part 2 and compressed, the air pushes the T-shaped piston 4 to slide and block the air inlet end of the exhaust pipe 5. After the storage cylinder 3 is fully pressurized, the connecting part 2 is vented by the control device. Since the pressure in the storage cylinder 3 is greater than the pressure in the connecting part 2, the pressure in the storage cylinder 3 pushes the T-shaped piston 4 to slide back to its original position and open the air inlet end of the exhaust pipe 5, thereby allowing the compressed gas in the storage cylinder 3 to be discharged instantly through the exhaust port of the exhaust pipe 5, thus unclogging the pipe.

[0033] The pressure gauge 20 of this utility model pipe cleaner is commercially available. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
