Description
Technical Field

Background
At present, when the inner wall of a pipeline is cleaned or blocked, a spray head which can extend into the pipeline is usually adopted to wash the inner wall surface of the pipeline at high pressure. In order to achieve the flushing effect, a higher flushing pressure is generally required to be applied to the spray head, so that the water sprayed by the spray head has a higher impact force. However, due to the relativity of the acting force, under the condition that the water sprayed by the spray head has higher impact force, the spray head also can be subjected to stronger back-resisting force, and is easy to fall out of the pipeline, so that serious safety accidents are caused, and the spray head is a great potential safety hazard in the operation process of an operator.
In order to solve the problem that the spray head is separated from the pipeline due to back force, a safe anti-fall-back device is arranged at one end of the pipeline to be cleaned, for example, a flange structure is arranged at one end of the pipeline, a fixing part is arranged on the flange structure, a movable connecting arm is arranged on the fixing part, one end of the connecting arm is connected with the fixing part, and the other end of the connecting arm is used for fixedly connecting the pipeline of the spray head, so that the spray head is prevented from being separated from the pipeline.
However, the existing anti-falling device has many defects:

third, still there is higher potential safety hazard, and the pipeline of connecting the shower nozzle is fixed through the one end of support arm, however, in order to realize the washing to different pipelines, the support arm need set movable structure to connect through the active structure between each part, wherein arbitrary one part appears becoming flexible, can cause the risk that the shower nozzle deviate from, and the potential safety hazard is higher.
Therefore, it is necessary to provide a structure for preventing the spray head from coming off the pipe simply and effectively.

The showerhead assembly 100 for cleaning a pipe according to an embodiment of the present invention includes: inlet connection 10, housing 20, retainer 30, spindle 40, spray head 50, and drive member 60.
Specifically, the inlet connector 10 has a liquid inlet 11, the housing 20 has a hollow cylindrical structure, and a first end of the housing 20 is connected to the inlet connector 10. The limiting member 30 is disposed on the inlet connection member 10 or the housing 20, the limiting member 30 is movable between an initial state and a limiting state along a radial direction of the housing 20, when the limiting member 30 is in the initial state, the limiting member 30 does not exceed an outer surface of the housing 20 in the radial direction of the housing 20, and when the limiting member 30 is in the limiting state, a part of the limiting member 30 extends out of the housing 20 in the radial direction of the housing 20 and abuts against an inner wall surface of a pipe to limit a position of the housing 20 in the pipe 200.
The shaft core 40 and the housing 20 are coaxially disposed in the housing 20, a first end of the shaft core 40 is communicated with the liquid inlet 11, the shaft core 40 is rotatable around its own axis, a second end of the shaft core 40 extends out of a second end of the housing 20, the shaft core 40 has a liquid passage penetrating along its axial direction, the liquid passage is communicated with the liquid inlet 11, the spray head 50 is connected with the second end of the shaft core 40, the spray head 50 is provided with a plurality of liquid outlets 51, the liquid outlets 51 are communicated with the liquid passage, the driving member 60 is disposed in the housing 20 or the inlet connector 10, and the driving member 60 is connected with the limiting member 30 to drive the limiting member 30.
In other words, the spray head assembly 100 according to the embodiment of the present invention may be used to clean the pipeline 200, and according to the diameter of the pipeline 200, the spray head assembly 100 with a corresponding size may be selected to clean or remove blockage of the pipeline, and during the use of the spray head assembly 100, the spray head assembly 100 is communicated with the external cleaning pipeline 300 (as shown in fig. 7), and the flushing water is pressurized by the external pressurizing structure and then sprayed through the spray head assembly 100 to achieve the cleaning or blockage removing effect.
The nozzle assembly 100 mainly comprises an inlet connector 10, a housing 20, a stopper 30, a shaft core 40, a nozzle 50 and a driving member 60, wherein the inlet connector 10 can be connected with an external pipe to introduce washing water, the inlet connector 10 is provided with a connecting structure connected with the external pipe, such as a threaded structure or a snap structure, and the liquid inlet 11 of the inlet connector 10 can introduce washing water of the external pipe. The housing 20 constitutes an outer main structure of the head assembly 100, the housing 20 is connected to the inlet coupling 10 to receive washing water introduced from the inlet coupling 10, and the housing 20 has a hollow structure and can be used to receive the shaft core 40 and introduce the washing water into the shaft core 40.
The shaft core 40 is coaxially arranged with the housing 20, and a liquid channel communicated with the liquid inlet 11 is arranged in the shaft core 40 to receive washing water introduced from the inlet connecting piece 10, a through hole is arranged on the side wall of the shaft core 40 and is inclined relative to the axial direction, and the through hole is communicated with the liquid channel of the shaft core 40, when high-pressure washing water flows out of the through hole from the liquid channel, the high-pressure washing water can drive the shaft core 40 to rotate around the axis of the shaft core 40 due to the inclined arrangement of the through hole. The second end of the shaft core 40 extends out of the shell 20, the part extending out of the shell 20 is provided with a spray head 50, the spray head 50 is provided with a plurality of liquid outlets 51, the liquid outlets 51 can spray high-pressure washing water, and the spray head 50 and the shaft core 40 rotate synchronously, so that the pipeline 200 can be washed or cleared in all directions.
Considering that the high-pressure washing water sprayed from the spray head 50 and the shaft core 40 generates backward back-pressure, when the back-pressure is too large, the spray head assembly 100 may be separated from the pipe 200, and there is a high safety risk.
Based on this, the nozzle assembly 100 according to the embodiment of the present invention further includes a limiting member 30 on the inlet connector 10 or the housing 20, the limiting member 30 is a limiting structure movable between an initial state and a limiting state, and when the limiting member 30 is in the initial state, an outer surface of the limiting member 30 does not exceed an outer surface of the housing 20, so that the entire nozzle assembly 100 can freely move in the pipeline 200, and a suitable cleaning position or angle is selected. When the position of the nozzle assembly 100 needs to be limited to avoid the nozzle assembly 100 from being separated from the pipe 200, a part of the limiting member 30 may extend out from the inlet connector 10 or the housing 20 under the action of the driving member 60, and a part of the limiting member 30 abuts against the inner wall surface of the pipe 200, so that when the friction force between the limiting member 30 and the inner wall surface of the pipe 200 is greater than the back-buckling force of the high-pressure washing water sprayed from the nozzle 50, the back-buckling force of the high-pressure washing water is difficult to overcome the friction force between the limiting member 30 and the inner wall surface of the pipe 200, so that the limiting member 100 and the pipe 200 form a limit, thereby effectively preventing the nozzle assembly 100 from being separated from the pipe 200, and greatly improving the use safety of the nozzle assembly 100.
When the showerhead assembly 100 for cleaning a pipe according to an embodiment of the present invention is used, first, the showerhead assembly 100 of a proper size and pressure is selected according to the size and use requirements of the pipe 200, and then the inlet connection 10 of the showerhead assembly 100 is connected to a flushing apparatus that can spray high pressure water.
As shown in fig. 7 and 8, before the spray head assembly 100 is inserted into the pipe 200 for cleaning, the flushing apparatus is closed, the stopper 30 is in an initial state, and the spray head assembly 100 can be freely inserted into the pipe 200.
As shown in fig. 9 and 10, after the spray head assembly 100 is inserted into the pipeline 200, the driving member 60 is controlled to drive the limiting member 30 to move from the initial state to the limiting state, so that a part of the limiting member 30 abuts against the inner wall surface of the pipeline 200, and the spray head assembly 100 and the pipeline 200 are ensured to be relatively fixed. And then, the flushing device is opened, when the pressure of the flushing device reaches a set value, the flushing device sprays high-pressure flushing water to the spray head assembly 100, the high-pressure flushing water is sprayed out from the liquid outlet 51 of the spray head 50, and the inner wall surface of the pipeline 200 is flushed or cleared.
Therefore, according to the nozzle assembly 100 for cleaning a pipeline of the embodiment of the present invention, the limiting member 30 is disposed on the inlet connector 10 or the housing 20, the limiting member 30 can be retracted into the inlet connector 10 or the housing 20 when the nozzle assembly 100 needs to adjust the flushing position of the nozzle 50, and the limiting member 30 extends out of the inlet connector 10 or the housing 20 and stops against the inner wall surface of the pipeline when the nozzle assembly 100 needs to be fixed, so as to limit the position of the nozzle assembly 100 in the pipeline, thereby avoiding the risk caused by the nozzle assembly 100 falling out of the pipeline, and having high safety, meanwhile, the nozzle assembly 100 does not need to add various parts to the outside of the pipeline 200 to fix the flushing structure to prevent the nozzle assembly from falling back, and has the advantages of simple structure, low cost, and fast assembly, and effectively ensuring the cleaning efficiency.
As shown in fig. 1 to 4, according to an embodiment of the present invention, the position-limiting member 30 is disposed in the inlet connector 10, the openings 12 are respectively disposed at two opposite sides of the inlet connector 10, and the position-limiting member 30 is disposed in each opening 12.
In other words, the position limiting member 30 of the nozzle assembly 100 according to the embodiment of the present invention is disposed on the inlet connector 10, the inlet connector 10 is used as a connecting structure for connecting with an external flushing pipe, and is easier to design than a structure of the housing 20 extending into the pipe 200, and the distance between the inlet connector 10 and the outside of the pipe 200 is the shortest during the cleaning process of the nozzle assembly 100, so that the driving member 60 can be conveniently controlled, thereby adjusting the position of the position limiting member 30 on the inlet connector 30. The opening 12 and the limiting member 30 are respectively disposed at two opposite sides of the inlet connection member 10, so that a contact area between an outer surface of the limiting member 30 and an inner wall surface of the pipe 200 can be ensured as much as possible, thereby ensuring a positioning effect of the limiting member 30 on the showerhead assembly 100 in the pipe 200.
Therefore, the limiting part 30 is arranged in the inlet connecting piece 10, so that the design is easy, the limiting part 30 is convenient to control through the driving piece 60, the structure is more reasonable, and the use is more convenient.
Optionally, in some embodiments of the present invention, the limiting member 30 includes a movable rod 31 and a limiting portion 32.
Specifically, as shown in fig. 5 and 6, the movable rod 31 is movable in the radial direction of the inlet connector 10, a first end of the movable rod 31 is connected to the driving member 60, and the limiting portion 32 is disposed at a second end of the movable rod 31, and when the limiting member 30 is in the limiting state, the limiting portion 32 extends out of the inlet connector 10 and abuts against the inner wall surface of the pipe.
In other words, the position limiting member 30 according to the embodiment of the present invention is mainly composed of two parts, namely, the movable rod 31 and the position limiting portion 32, wherein the movable rod 31 is a rod-shaped structure movable in the radial direction of the inlet connector 10, a first end of the movable rod 31 is connected to the driving member 60 and is driven by the driving member 60, and a second end of the movable rod 31 is provided with the position limiting portion 32. When the movable rod 31 moves, the limiting portion 32 and the movable rod 31 move synchronously, the limiting portion 32 may be adapted to abut against the inner wall surface of the pipeline 200 to form a limiting structure, and the area of the outer surface of the limiting portion 32 may be larger than the area of the second end of the movable rod 31, so as to increase the contact area with the inner wall surface of the pipeline 200.
The first end of the movable rod 31 passes through the opening 12 and is disposed in the inlet connector 10, and is movable in the opening 12, and when the limiting member 30 is in the initial state, the second end of the movable rod 31 and the limiting portion 32 do not exceed the outer surface of the inlet connector 10, that is, the second end of the movable rod 31 and the limiting portion 32 may be disposed in the opening 12, or the outer surface of the limiting portion 32 may be flush with the outer surface of the inlet connector 10; when the position limiting member 30 is in the position limiting state, the second end of the movable rod 31 and the position limiting portion 32 extend out of the opening and beyond the outer surface of the inlet connector 10, and the outer surface of the position limiting portion 32 abuts against the inner surface of the pipeline 200 to form the position limiting.
In the case that the area of the outer surface of the limiting portion 32 is larger than the area of the second end of the movable rod 31, a sunken groove corresponding to the shape of the limiting portion 32 may be provided at the opening 12 of the inlet connector 10, so that in the case that the limiting member 30 is in the initial state, the limiting portion 32 may be located in the sunken groove, thereby ensuring that the outer surface of the limiting portion 32 is flush with the outer surface of the inlet connector 10.
Therefore, the limiting part 30 is arranged to be of a structure consisting of the movable rod 31 and the limiting part 32, so that the structure is simple, the movement and the assembly of the limiting part 30 are convenient to realize, and the operation is more convenient.

The surface of the limiting part 32 is provided with a plurality of limiting protrusions 321, and the limiting protrusions 321 can effectively increase the friction force with the inner wall surface of the pipeline 200, thereby further ensuring the limiting effect of the limiting member 30 and the inner wall surface of the pipeline 200.

Specifically, as shown in fig. 7 and 8, when the driving element 60 moves in a direction away from the limiting element 30 along the axial direction of the inlet connector 10, that is, when the driving element 60 moves to the right, the inclined surface of the second engaging portion 61 no longer abuts against the inclined surface of the first engaging portion 311, an elastic element 70 may be disposed between the limiting element 30 and the sidewall of the opening 12, the limiting element 30 may be retracted into the opening in the radial direction of the inlet connector 10 under the pulling force of the elastic element 70, at this time, the limiting element 30 may be in an initial state, the outer surface of the limiting element 30 does not exceed the outer surface of the inlet connector 10, and the spray head assembly 100 may move freely in the pipe 200.
