Description

Technical Field

[0001] This utility model relates to the field of sewer unblocking technology, specifically a sewer blockage unblocking device. Background Technology

[0002] Currently, there are many types of sewer unblocking devices on the market, but they all suffer from several problems that urgently need to be addressed. One particularly prominent deficiency is the lack of an effective foot pedal mechanism. During manual inflation, the lack of stable support and a fixed structure makes it difficult for operators to properly restrain the device, causing it to wobble easily. This wobbling not only increases the difficulty of operation, making inflation laborious and inefficient, but also poses a significant safety hazard, potentially causing accidental injury to the surrounding environment or operators due to the device's instability.

[0003] As a key component in manual air pumping operations, the structural strength of the air pump handle is also a crucial factor. Some existing drain unclogging devices have rudimentary air pump handle designs, lacking necessary internal reinforcement. During prolonged and frequent pumping operations, the air pump handle is prone to deformation or even damage due to uneven stress or excessive fatigue, thus affecting the normal operation of the device, shortening its lifespan, and increasing operating costs.

[0004] As a key component displaying the internal air pressure of a drain cleaning device, the proper placement of the pressure gauge directly affects the user experience. However, in some current drain cleaning devices, the pressure gauge is improperly positioned, making it difficult for operators to directly observe the displayed value during manual air pumping. This prevents operators from monitoring real-time pressure changes within the device, making it difficult to accurately control the pumping progress and intensity. This can easily lead to insufficient or excessive air pumping, affecting the unblocking effect and potentially damaging the device.

[0005] Furthermore, the lack of effective protection measures for the vent switch, a key component in the control device for venting, is also a significant problem. Existing vent switches are typically exposed without any protective structure, making them prone to accidental venting during transportation, storage, or use of the device. Accidental venting not only wastes the high-pressure gas stored inside the device and reduces venting efficiency, but also poses a serious safety hazard, potentially causing injury to surrounding personnel or objects due to the sudden release of high-pressure gas. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a sewer blockage unblocking device, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sewer blockage unblocking device, comprising:

[0008] Outer steel cylinder;

[0009] The foot pedal is fixed to the bottom of the outer steel cylinder. The foot pedal includes a sleeve installed at the bottom of the outer steel cylinder, and pedals are fixedly connected to both sides of the sleeve.

[0010] The air pump handle is located above the outer steel cylinder, and its interior is equipped with several intersecting reinforcing ribs.

[0011] The pressure gauge is located above the outer steel cylinder;

[0012] The handle is connected to the upper part of the outer steel cylinder, and a venting switch is slidably connected inside it.

[0013] Furthermore, the sewer blockage unblocking device also includes an upper sealing cap, which is fixedly connected to the top of the outer steel cylinder. A pressure detection connector is connected to one side of the upper sealing cap, and the pressure detection connector is connected to the inside of the outer steel cylinder.

[0014] Furthermore, the handle is installed in conjunction with the upper sealing cover, and an air pipe is installed inside the handle. The air outlet of the air pipe is connected to the detection port of the pressure gauge, and the air inlet is connected to the air outlet of the pressure detection connector.

[0015] Furthermore, the sewer blockage unblocking device also includes an air pump, which is fixed inside the outer steel cylinder. Inside the air pump, a piston is movably installed. The top of the piston is connected to a piston rod, and the top of the piston rod extends above the handle and is fixedly connected to the air pump handle. A one-way valve is installed at the bottom of the air pump.

[0016] Furthermore, the sewer blockage unblocking device also includes a lower sealing cover, which is fixedly connected to the bottom end of the outer steel cylinder. The lower sealing cover is equipped with a venting-related structure, and the venting switch is linked with the venting-related structure to control the gas discharge inside the outer steel cylinder.

[0017] Furthermore, the venting-related structure includes a venting fixed support, a venting connecting rod, a venting piston, a spring, and a venting port. The venting fixed support is installed on the top of the lower sealing cover. The venting connecting rod is slidably connected inside the upper sealing cover, and its top end is hinged to the venting switch. The venting piston is connected to the bottom end of the venting connecting rod and extends into the venting fixed support. The spring is sleeved on the bottom of the venting connecting rod, and its two ends abut against the venting fixed support and the venting piston, respectively. The venting port is opened inside the lower sealing cover and is sealed by the venting piston.

[0018] Furthermore, an air vent connector is installed inside the vent port, and a clearance hole is provided at the bottom end of the sleeve. The bottom end of the air vent connector extends to the outside through the clearance hole, and the air vent connector is set as an elbow or a straight head.

[0019] Furthermore, the top of the upper sealing cover is also equipped with a one-way valve for an electric air pump, which is used to connect the air outlet pipe of an external air pump to enable the external air pump to inflate.

[0020] This utility model provides a sewer blockage unblocking device. Compared with the prior art, it has the following advantages:

[0021] 1. A foot pedal is included, comprising a sleeve and two side pedals, allowing the user to place both feet on the pedals while inflating the device, providing stable restraint. This design effectively solves the problem of device swaying during inflation, reduces operational difficulty, makes the inflation process easier and more efficient, and avoids potential accidental injuries caused by device swaying, thus improving safety.

[0022] 2. The air pump handle is equipped with several intersecting reinforcing ribs, which significantly enhances the structural strength of the air pump handle. During long-term and frequent air pumping operations, the reinforcing ribs can effectively distribute the force on the handle, preventing the handle from deforming or even being damaged due to uneven force or excessive fatigue, thereby extending the service life of the device, reducing operating costs, and ensuring the normal use of the device;

[0023] 3. This device installs the pressure gauge inside the handle above the outer steel cylinder, corresponding to the air pump handle. This thoughtful design allows users to directly observe the pressure changes displayed on the gauge while manually pumping air. Users can accurately control the pumping progress and intensity based on the pressure readings, avoiding under- or over-pumping, improving the unblocking effect, and ensuring the safe use of the device.

[0024] 4. This device integrates the vent switch with a sliding connection inside the handle, providing a degree of protection for the switch. During daily transportation, storage, or use, the concealed location of the vent switch reduces the likelihood of accidental activation. Venting is only triggered when the user actively presses the vent switch in the handle, thus preventing accidental release, effectively utilizing the high-pressure gas stored within the device, improving drainage efficiency, and eliminating the potential for injury to surrounding personnel or objects due to accidental release, thereby enhancing the safety of the device.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0035] Please see Figure 1-8 This utility model provides a technical solution: a sewer blockage unblocking device, mainly including an outer steel cylinder 1, a foot pedal 2, an air pump handle 3, and a pressure gauge 4. The foot pedal 2 is fixed to the bottom of the outer steel cylinder 1. The foot pedal 2 includes a sleeve 21 installed at the bottom of the outer steel cylinder 1. The two sides of the sleeve 21 are fixedly connected to pedals 22. The air pump handle 3 and the pressure gauge 4 are both located above the outer steel cylinder 1. The air pump handle 3 has several intersecting reinforcing ribs 31 inside. The upper part of the outer steel cylinder 1 is connected to a handle 5. The handle 5 is slidably connected to a release switch 6 inside. The pressure gauge 4 is installed inside the handle 5 and corresponds to the air pump handle 3.

[0036] The top of the outer steel cylinder 1 is fixedly connected to the upper sealing cover 7. One side of the upper sealing cover 7 is connected to the pressure detection connector 71. The pressure detection connector 71 is connected to the inside of the outer steel cylinder 1. The handle 5 is also equipped with an air pipe 41. The air outlet of the air pipe 41 is connected to the detection air port of the pressure gauge 4, and the air inlet of the air pipe 41 is connected to the air outlet of the pressure detection connector 71.

[0037] An air pump 9 is fixed inside the outer steel cylinder 1. A piston 10 is movably installed inside the air pump 9. The top of the piston 10 is connected to a piston rod 11. The top of the piston rod 11 extends above the handle 5 and is fixedly connected to the air pump handle 3. A one-way valve 12 is installed at the bottom of the air pump 9. When the air pump handle 3 pushes the piston rod 11 and the piston 10 together to move down inside the air pump 9, it will compress the air inside the air pump 9. After the air is under pressure, it will be discharged into the outer steel cylinder 1 through the one-way valve 12. That is to say, the air is stored inside the outer steel cylinder 1. Because of the irreversibility of the one-way valve 12, even if the air pressure inside the outer steel cylinder 1 is greater than the air pressure inside the air pump 9, the air inside the outer steel cylinder 1 will not flow backward into the air pump 9. The air can only flow from the air pump 9 to the outer steel cylinder 1.

[0038] The bottom end of the outer steel cylinder 1 is fixedly connected to the lower sealing cover 8, and the top end of the lower sealing cover 8 is equipped with a venting fixing support 13. The upper sealing cover 7 is slidably connected to the venting connecting rod 14. A sealing ring 72 is provided at the sliding point to improve the sealing effect. The top end of the venting connecting rod 14 is hinged to the venting switch 6, and the bottom end extends into the interior of the venting fixing support 13 and is connected to the venting piston 15. A spring 16 is sleeved at the bottom of the venting connecting rod 14. The two ends of the spring 16 abut against the venting fixing support 13 and the venting piston 15, respectively. A venting port 17 is reserved inside the lower sealing cover 8. The venting piston 15 seals the venting port 17. A venting connector 18 is installed inside the venting port 17. The bottom end of the sleeve 21 is provided with a clearance hole 23. The bottom end of the venting connector 18 extends to the outside through the clearance hole 23. The venting connector 18 is set as an elbow or a straight head (elbow as shown in the attached diagram). Figure 6 As shown, the straight head is attached. Figure 1 As shown, the advantage of setting the vent connector 18 as an elbow is that, when inflating air, because the elbow extends from the side of the sleeve 21, the foot pedal 2 can be placed directly on the ground without needing to hold it while inflating, which improves convenience. The specific choice depends on the different sewer structures.

[0039] The top of the upper sealing cover 7 is also equipped with an electric air pump one-way connection valve 19. The air outlet pipe of the external air pump can be connected to the electric air pump one-way connection valve 19, so that the device can be inflated by manual air pumping or by using an external air pump, which improves the practicality of the device.

[0040] During the use of this device:

[0041] When manually inflating the air, the user repeatedly lifts and presses the air pump handle 3, which drives the piston 10 to move up and down inside the air pump 9 via the piston rod 11. During the descent, the piston 10 compresses the air inside the air pump 9 and discharges it to the outer steel cylinder 1 for storage through the one-way valve 12. By repeating this operation, the air pressure in the outer steel cylinder 1 will continuously increase, and the air pressure value will be displayed on the pressure gauge 4. This allows the user to observe the changes in the air pressure value displayed on the pressure gauge 4 while inflating the air. During the inflating process, the user's feet can be placed on the two pedals 22 to restrain the device and prevent it from shaking during inflating. When the air pressure reaches the set pressure, inflating is stopped, the foot pedal 2 is removed, and the required vent connector 18 is installed inside the vent port 17. A vent connector 18 is then installed at the end of the vent connector 18. Install the horn-shaped sealing piece 20, insert the vent connector 18 into the sewer inlet, and use the horn-shaped sealing piece 20 to block the sewer inlet. After blocking, press the vent switch 6 in the handle 5, causing the vent switch 6 to move upward, which in turn moves the vent connecting rod 14 and the vent piston 15 upward, and the spring 16 is compressed. When the vent piston 15 moves upward, the vent port 17 is opened, and the high-pressure gas inside the outer steel cylinder 1 will instantly enter the vent connector 18 and spray towards the blockage in the sewer. After use, stop pressing the vent switch 6. Under the reaction force of the spring 16, push the vent switch 6, the vent connecting rod 14, and the vent piston 15 downward, and the vent piston 15 re-blocks the vent port 17 to prepare for the next inflation.

[0042] When using an external air pump for inflation, the air pipe of the external air pump can be directly connected to the one-way valve 19 of the electric air pump. After starting the air pump, the gas enters the outer steel cylinder 1 through the one-way valve 19 of the electric air pump. Similarly, stop when the pressure reaches the required level. Subsequent operations are the same as manual inflation. Example 2

[0043] Please see Figure 7 The sewer blockage clearing device in this embodiment differs from that in embodiment 1 in that, when clearing a sewer blockage, the foot pedal 2 and the vent connector 18 can be completely removed, exposing the vent 17, and the lower sealing cover 8 can act as a sealing component 20 to block the sewer inlet, achieving the same effect.
