Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging equipment technology, specifically to an intelligent positive and negative pressure dredging device. Background Technology

[0002] Sewer pipes and sewage pipes are mainly used for the circulation of sewage, but due to the presence of garbage, foreign objects and other factors in sewage, improper discharge can often cause blockages in the pipes.

[0003] For unclogging drains, methods such as poking with thin, long objects or using clamps can be employed. However, these methods are very difficult to use when unclogging drains with bends. Alternatively, pressure-based methods can be used, such as toilet plungers and drain cleaners. However, both traditional and piston-type toilet plungers require frequent manual operation to generate pressure, which is inconvenient and has limited pressure. They may not be effective in clearing complex blockages, especially severe ones, and can easily splash everywhere if not handled carefully. Drain cleaners with built-in air pumps are often bulky, especially in the confined space of a bathroom. Using large air pumps can be difficult, and excessive pressure can damage the pipes or cause large objects to become stuck inside the drain, making unclogging even more challenging.

[0004] See the patent with publication number CN221760823U, which discloses a handheld pipe cleaner. It provides a cleaner with a simple structure, convenient operation, and more universal and flexible working method. However, its operation is completely dependent on manual labor and has poor intelligence. Summary of the Invention

[0042] like Figure 1 , 2 The intelligent positive and negative pressure drain cleaner shown mainly includes a tank 1, a pump assembly, a suction assembly, and a monitoring assembly. The following is a detailed description of each component.

[0043] The drain cleaner is centered on tank 1, with the pump assembly, suction assembly, and monitoring assembly all installed around tank 1. A chamber is formed inside tank 1, with a drain port at the bottom of tank 1. The connection between the pump assembly and tank 1 is located at the top of tank 1, and the connection between the suction assembly and tank 1 is located at the bottom of tank 1.

[0044] The pump assembly includes a pump body 20 and a power supply 21. The pump body 20 communicates with the chamber and provides positive or negative pressure to it. The power supply 21 is connected to the pump body 20 and supplies power to it. The pump body 20 can be a piston pump (application number CN2025202821887). The power supply 21 uses a battery for easy transport of the drain cleaner; alternatively, an external AC power source can be used.

[0045] The suction assembly includes a tube body 30, a plug 31, and a valve body 32. One end of the tube body 30 communicates with the chamber, the plug 31 is connected to the other end of the tube body 30, and the valve body 32 is mounted on the tube body 30 to control the opening and closing of the tube body 30. The valve body 32 is equipped with an operating handle 33 to control the switching state of the valve body 32. For the specific structure of the suction assembly, please refer to the structures disclosed in publication numbers CN212427388U and CN221760823U, which will not be elaborated further here.

[0046] like Figure 3 As shown: The monitoring component includes a main board component 40, an operation panel 41, a liquid level monitoring component (not shown in the figure), and a pressure monitoring component (not shown in the figure). The main board component 40 is connected to the pump body 20, the operation panel 41, the liquid level monitoring component, and the pressure monitoring component. This connection can be a wired connection or a signal connection. Specifically:

[0047] The control panel 41 includes a start / stop control component 410 and a pressure control component 411. The start / stop control component 410 is used to start and stop the pump body 20, as shown in the figure, in the form of a button, to turn the pump body 20 on or off. The pressure control component 411 is used to control the pressure condition of the chamber, as shown in the figure, in the form of a knob. Turning left is the negative pressure condition, and turning right is the positive pressure condition. One knob can switch between the two conditions.

[0048] The control panel also includes a positive / negative pressure display 412 and a liquid level warning device 413. The positive / negative pressure display 412 is used to display the positive / negative pressure status in the chamber. As shown in the figure, the left side is the negative pressure status, which can be used for suction, and the right side is the positive pressure status, which can be used for drainage and flushing. The display is more intuitive through the panel bar, and the various states of positive pressure, negative pressure, drainage, and no pressure are simple and clear. The liquid level warning device 413 is used to display the liquid drainage indicator in the chamber. If the liquid level in the chamber exceeds the standard, the liquid level warning device 413 can be used to prompt for drainage.

[0049] The liquid level monitoring component is used to monitor the liquid level height in the chamber. If the liquid accumulation in the chamber of tank 1 exceeds a certain amount, it is easy to enter the pump body 20 and affect its service life. The detection of the liquid level height can protect the pump body 20. The pressure monitoring component is used to monitor the pressure value in the chamber. The liquid level monitoring component and the pressure monitoring component can be made of sensors, etc.

[0050] The mainboard component 40 is configured to control the start and stop of the pump body 20 according to the instructions of the start / stop operation component 410, to control the stop of the pump body 20 according to the liquid level height monitored by the liquid level monitoring component, and to control the stop of the pump body 20 according to the set pressure value and the pressure value monitored by the pressure monitoring component. Specifically: the operation instructions of the start / stop operation component 410 and the pressure control component 411 are sent to the mainboard component 40, which then issues control instructions to the operating conditions of the pump body 20, and the pump body 20 performs positive / negative pressure suction; the liquid level monitoring component monitors the liquid level height in the chamber and sends a signal to the mainboard component 40. When the liquid level height reaches the required drainage threshold, the mainboard component 40 issues a stop instruction to the pump body 20, and the pump body 20 stops, while the liquid level warning component 413 provides a warning; the pressure monitoring component monitors the pressure value in the chamber and sends a signal to the mainboard component 40. When the pressure value reaches the set pressure value, the mainboard component 40 issues a stop instruction to the pump body 20, and the pump body 20 stops. Figure 4 As shown.

[0051] The drain cleaner also includes a top frame 5, a cover 6, a handle 7, a moving assembly, and a fixed frame 9. Specifically:

[0052] The top frame 5 is connected to the top of the tank 1, the pump body 20 is connected to the top frame 5, and the cover 6 is placed on the top of the tank 1 and covers the pump body 20. At the same time, the power supply 21 is connected to the outside of the cover 6, so that the power supply 21 can be removed for charging or replacement. The operation panel 41 is also connected to the outside of the cover 6 for easy operation. The main board component 40 is connected to the inside of the cover 6. The cover 6 can protect the easily damaged pump body 20 and main board component 40.

[0053] One end of the handle 7 is connected to the tank 1, and the other end of the handle 7 extends through the cover 6 for operation. The drain cleaner can be easily moved to the area that needs to be unclogged through the handle 7.

[0054] The movable component is also connected to the tank 1, facilitating the transport of the drain cleaner and saving manpower. In this embodiment, the movable component includes a base frame 80, rollers 81, and a push rod 82. The base frame 80 is connected to the bottom of the tank 1, and the lower ends of the rollers 81 and the push rod 82 are connected to the base frame 80. Two rollers 81 can be provided to ensure the stability of movement, and the push rod 82 can be a telescopic rod for easy height adjustment.

[0055] The mounting bracket 9 is also connected to the tank 1. The mounting bracket 9 is used to fix the suction assembly, specifically to fix the suction assembly when it is not in use, making the storage of the drain cleaner more compact. In the figure, the mounting bracket 9 is a bayonet, which can hold the tube 40 of the suction assembly in place.

[0056] During use: Pump 20 switches to negative pressure mode and instantly sucks out the blockage in the pipe through the chamber and suction component. Generally, blocked pipes usually contain sewage. During unblocking, the sewage in the pipe may be sucked into the chamber of tank 1. When the liquid in the chamber reaches the required drainage threshold, the pump will stop and switch pump 20 to positive pressure mode to discharge the sewage from the chamber.

[0057] If it is necessary to thoroughly clean the residue inside the pipe, first switch the pump body 20 to negative pressure mode to let clean water enter the chamber, then switch to positive pressure mode and flush the clean water into the pipe through high pressure to thoroughly clean it and prevent later accumulation and blockage.

[0058] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
