Description

Technical Field

[0001] This utility model belongs to the field of pipeline cleaning technology, specifically a nozzle with switchable cleaning angle. Background Technology

[0002] In sewage discharge pipes and other fluid discharge pipes, the deposition of dirt on the pipe walls necessitates regular cleaning to ensure unobstructed flow. Current pipe cleaning processes utilize nozzles with switchable cleaning angles, which spray high-pressure cleaning fluid to remove deposits from the pipe walls. While these nozzles offer various nozzle orifice sizes to suit different pipe types and deposit conditions for effective cleaning, their fixed orifice sizes necessitate nozzle replacement for different deposit types, resulting in time-consuming, labor-intensive, and costly cleaning. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a nozzle with switchable cleaning angle, which can adjust the cleaning intensity and the moving speed inside the pipe, making it suitable for different pipes and adapting to different deposition conditions, thus ensuring the cleaning effect.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A nozzle with switchable cleaning angle is installed at the front end of a cleaning hose supplying high-pressure cleaning fluid. It moves inside the hose through the jet of the high-pressure cleaning fluid, cleaning the interior of the hose. The nozzle includes a main body, a drive unit, and a column. The drive unit is mounted on the main body, which has a receiving cavity communicating with the hose. The main body has a first jet hole group and a second jet hole group. The column is movably installed within the receiving cavity, and has a flow channel communicating with the receiving cavity. The column has one or more through holes communicating with the flow channel. The drive unit drives and connects to the column, causing it to move back and forth between a first position and a second position within the receiving cavity. When the column is in the first position within the receiving cavity, the first jet hole group communicates with the flow channel through the through holes, while the outer wall of the column blocks the second jet hole group. When the column is in the second position within the receiving cavity, the second jet hole group communicates with the flow channel through the through holes, while the outer wall of the column blocks the first jet hole group.

[0006] Furthermore, the drive unit includes a first drive unit and a second drive unit. The first drive unit and the second drive unit work alternately to keep the column in a first position and a second position, respectively.

[0007] Furthermore, the main body has a third group of injection holes. When the first drive unit and the second drive unit work synchronously, they will drive the column to stop in the third position in the receiving cavity. When the column is in the third position, the third group of injection holes is connected to the flow channel through the through hole, while the outer wall of the column blocks the first group of injection holes and the second group of injection holes.

[0008] Furthermore, the first drive unit has a first coil, which is connected to the main body and arranged coaxially with the column portion; the second drive unit has a second coil, which is connected to the main body and arranged coaxially with the column portion; and the first coil and the second coil are arranged sequentially along the axial direction of the column portion.

[0009] Furthermore, the column portion has a first iron ring portion and a second iron ring portion arranged sequentially along the axial direction of the column portion. The first ring portion is arranged close to the inner side of the first coil so that when the first coil is energized and the second coil is de-energized, the first coil will magnetically attract the first ring portion, causing the column portion to move towards a first position. The second ring portion is arranged close to the inner side of the second coil so that when the second coil is energized and the first coil is de-energized, the second coil will magnetically attract the second ring portion, causing the column portion to move towards a second position.

[0010] Furthermore, the first coil and the second coil are respectively disposed in the first mounting groove and the second mounting groove on the inner wall of the main body, and the first ring body and the second ring body are respectively disposed in the third mounting groove and the fourth mounting groove on the outer wall of the column body.

[0011] Furthermore, the first driving unit has a first coil, which is coaxially arranged with the main body and the column part, and the second driving unit is specifically an electromagnet.

[0012] Furthermore, the driving unit includes a first driving unit and a reset unit. When the first driving unit is working, it can drive the column part to move to a first position in the storage cavity. When the first driving unit stops working, the reset unit can drive the column part to reset to a second position. The reset unit is specifically a spring or a permanent magnet.

[0013] Furthermore, the main body is provided with a first annular groove that connects all the first injection holes in the first injection hole group and a second annular groove that connects all the second injection holes in the second injection hole group, so that when the column is stopped in the first position, all the through holes are indirectly connected to all the first injection holes through the first annular groove, and when the column is stopped in the second position, all the through holes are indirectly connected to all the second injection holes through the second annular groove.

[0014] Furthermore, the through hole is a strip-shaped hole extending axially along the column part.

[0015] The beneficial effects of this utility model are as follows: The nozzle with switchable cleaning angle provided in this application has a cylindrical part coaxially sleeved inside the main body, and multiple sets of different types of spray holes are opened on the side wall of the main body. Through holes communicating with the internal flow channel are opened on the side wall of the cylindrical part. The through holes can be connected to the multiple sets of spray holes to form multiple different channels. The cylindrical part is driven to move axially within the main body by the driving part, so that the high-pressure cleaning fluid in the nozzle with switchable cleaning angle can switch between being sprayed outward through multiple different channels. The nozzle with switchable cleaning angle moves inside the tube and cleans the inside of the tube. By setting the multiple sets of spray holes to different apertures or tilt angles, the spray volume of high-pressure cleaning fluid and the spray angle relative to the inner circumference of the tube can be changed, so as to adjust the cleaning intensity and the moving speed of the nozzle with switchable cleaning angle inside the tube. This makes it suitable for different tubes and adaptable to different deposition conditions to ensure the cleaning effect. Attached Figure Description

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] This invention provides a nozzle with a switchable cleaning angle, installed at the front end of a cleaning hose supplying high-pressure cleaning fluid. The nozzle moves inside the hose as the high-pressure cleaning fluid is sprayed, cleaning the interior of the hose. Figure 1-2 As shown, the nozzle with switchable cleaning angle includes a main body 1, a cylindrical part 2, and a drive part. The main body 1 has a receiving cavity 3 connected to a flexible hose. The cleaning hose is inserted into the receiving cavity 3 and sealed to the nozzle with switchable cleaning angle to deliver high-pressure cleaning fluid into the receiving cavity 3. The cylindrical part 2 is movably installed within the receiving cavity 3. The cylindrical part 2 is coaxially arranged with the main body 1, and its outer wall is fitted against the inner wall of the main body 1. The cylindrical part 2 has a flow channel 4 connecting to the receiving cavity 3, allowing the high-pressure cleaning fluid entering the receiving cavity 3 to flow into the flow channel 4.

[0030] A first injection hole group 11 and a second injection hole group 12 are provided on the side wall of the main body 1, which penetrate the side wall of the main body 1. The first injection hole group 11 and the second injection hole group 12 are arranged sequentially along the axial direction of the main body 1. The first injection hole group 11 includes a plurality of first injection holes evenly distributed along the circumferential direction of the main body 1, and the second injection hole group 12 includes a plurality of second injection holes evenly distributed along the circumferential direction of the main body 1.

[0031] One or more through holes 21 communicating with the flow channel 4 are provided on the side wall of the column part 2, and the outer wall of the column part 2 is slidably connected to the inner wall of the main body part 1. The drive unit is mounted on the main body part 1, and the drive unit drives the column part 2 and can drive the column part 2 to move axially within the main body part 1. The drive unit drives the column part 2 to move back and forth between the first position and the second position within the receiving cavity 3. When the column part 2 is in the first position within the receiving cavity 3, the first spray hole group 11 is connected to the flow channel 4 through the through hole 21 to form a first channel. At the same time, the outer wall of the column part 2 blocks the second spray hole group 12. When the column part 2 is in the second position within the receiving cavity 3, the second spray hole group 12 is connected to the flow channel 4 through the through hole 21 to form a second channel. At the same time, the outer wall of the column part 2 blocks the first spray hole group 11. This allows the high-pressure cleaning fluid in the flow channel 4 to switch between being sprayed outward through the first channel and being sprayed outward through the second channel. This drives the nozzle with switchable cleaning angle to move inside the tube and clean the inside of the tube. By setting the first external spray hole and the second external spray hole to different diameters or tilt angles, the spray volume of the high-pressure cleaning fluid and the spray angle relative to the inner circumference of the tube can be changed, thereby adjusting the cleaning intensity and the moving speed of the nozzle with switchable cleaning angle inside the tube.

[0032] Preferably, such as Figure 3-4 As shown, the inner wall of the main body 1 is provided with a first annular groove 14 connecting all the first injection holes in the first injection hole group and a second annular groove 15 connecting all the second injection holes in the second injection hole group, so that when the column part 2 is stopped in the first position, all the through holes 21 are indirectly connected to all the first injection holes through the first annular groove 14, and when the column part 2 is stopped in the second position, all the through holes 21 are indirectly connected to all the second injection holes through the second annular groove 15. The through holes 21 are set as strip-shaped holes extending along the axial direction of the column part 2, which can increase the position range in which the through holes 21 are connected to the first annular groove 14 and the second annular groove 15 when the column part 2 is stopped in the first position and the second position, respectively, thereby reducing the requirements for the adjustment accuracy of the drive part.

[0033] The drive unit includes a first drive unit and a second drive unit. The first drive unit and the second drive unit work alternately to make the column part 2 stop at the first position and the second position respectively.

[0034] Preferably, a third jet hole group is provided on the side wall of the main body 1, penetrating the side wall of the main body 1. The third jet hole group is located between the first jet hole group 11 and the second jet hole group 12, and includes a plurality of third jet holes evenly distributed along the circumference of the main body 1. When the first drive unit and the second drive unit work synchronously, they will drive the column part 2 to stop in the third position within the receiving cavity 3. When the column part 2 is in the third position, the third jet hole group is connected to the flow channel 4 through the through hole 21 to form a third channel. At the same time, the outer wall of the column part 2 blocks the first jet hole group 11 and the second jet hole group 12. A third annular groove is provided on the inner wall of the main body 1 to connect all the third jet holes in the third jet hole group. When the column part 2 is stopped in the third position, all the through holes 21 are indirectly connected to all the third jet holes through the third annular groove.
