Description

Technical Field

[0001] This utility model belongs to the field of pipeline rotation and reversing technology, and in particular relates to a pipeline rotation and reversing installation structure. Background Technology

[0002] With the increasing popularity of intelligent cleaning equipment, pool cleaning equipment has gradually become an important tool for improving pool maintenance efficiency. Currently, the reversing drive technology of pool cleaning equipment generally adopts mechanical transmission or electromagnetic valve control schemes.

[0003] For example, some devices use a sealed partition to drive a multi-stage gear set to make the spray nozzle swing, while others use a hydraulic servo system to switch the water flow channel, but such structures have significant drawbacks:

[0004] Firstly, mechanical transmission components require precision machining and are susceptible to water corrosion. During assembly, the gear meshing angle must be strictly aligned, and after long-term use, they are prone to jamming due to scale buildup.

[0005] Secondly, the electromagnetic valve control system requires supporting circuit modules, pressure sensors and feedback mechanisms, which are not only costly, but also susceptible to interference in humid environments and have insufficient stability. Utility Model Content

[0006] The purpose of this utility model is to provide a pipe rotation reversing installation structure to solve the pain points of the prior art mentioned in the background, such as structural redundancy, high operation threshold, and high maintenance cost, which makes it difficult to significantly improve the convenience and reliability of operation while ensuring reversing accuracy.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A pipe rotation and reversing installation structure includes a shell with a water inlet and a water outlet, wherein the water outlet and the water inlet are interconnected with the inner cavity of the shell to form a flow channel for liquid flow.

[0008] A grid assembly for switching the flow direction of a liquid, the grid assembly including a rotatable grid sleeve, the inner cavity of which is provided with a horizontal baffle for flexibly changing the flow direction of the liquid, and at the same time, the inner cavity of which is provided with a vertical baffle symmetrically arranged at ninety degrees with the horizontal baffle.

[0009] Preferably, a water channel assembly is horizontally placed inside the shell cavity, the water channel assembly including an inner water channel and an outer water channel;

[0010] The grating assembly is installed in the inner cavity of the outer pipe of the waterway and is interconnected with the inner cavity of the inner pipe of the waterway.

[0011] Preferably, a fixing member is provided below the inner tube of the waterway, and the fixing member is bolted to the inner wall of the shell. An auxiliary fitting is fitted on the left side of the inner tube of the waterway.

[0012] Preferably, two sets of inserts are symmetrically connected on the right side of the outer water pipe along the axis, and two baffles are symmetrically arranged on the outer water pipe along the axis. The surfaces of the two baffles at opposite ends are provided with slots for use with the inserts.

[0013] Preferably, the baffle is made of flexible silicone material and is used to open and close the opening at the end of the outer pipe away from the inner pipe of the waterway.

[0014] Preferably, a fixing knob is fitted on the outer surface of the waterway outer pipe, and a limiting plate is connected to the right side of the fixing knob. The limiting plate is used to limit the grid sleeve and the baffle, while multiple buckles are provided on the left side of the fixing knob.

[0015] Preferably, the diameter of the fixed knob is larger than the diameter of the limiting plate, and there are two buckles arranged symmetrically to each other.

[0016] Preferably, one end of the outer surface of the grid sleeve is connected to a positioning protrusion, and the top of the inner cavity of the water channel outer pipe and the right side of the inner cavity are provided with groove one and groove two for cooperating with the positioning protrusion.

[0017] Preferably, the grooves one and two have the same cavity specifications, and the grooves one and two are symmetrically arranged at ninety degrees on the inner wall of the waterway outer pipe.

[0018] Preferably, the inner cavity of the waterway inner tube is provided with an impeller, and a motor is provided on the side of the impeller away from the waterway inner tube. The output shaft of the motor is connected to the shaft end of the impeller, and a sealing baffle is provided on the fixed end of the motor.

[0019] The pipe rotation and reversing installation structure of this utility model has the following advantages:

[0020] This is a rotating and reversing pipe installation structure. Water flows into the inner cavity through the inlet hole of the shell, then is guided by the water channel assembly (comprising the inner and outer water channels) to the grating sleeve. Finally, it passes through the grating assembly and is discharged through the outlet, using the water as propulsion to move the pool cleaning robot. To change the robot's direction, the vertical partition is pinched and rotated 90° clockwise, causing the entire grating sleeve to rotate, changing the horizontal partition from a vertical to a horizontal position, thus altering the water flow direction. The integrated "convex" design of the inner and outer water channels, along with fasteners and auxiliary components, allows for quick assembly. The grating sleeve ensures stability during the 90° rotation switching through positioning protrusions and limiting engagement with grooves one and two. The flexible baffle is detachably connected to the slot via inserts and automatically bends under water flow impact to spray water. The fixing knob, through a snap-fit ​​and limiting plate, provides bidirectional restraint to the grating sleeve and baffle, preventing components from detaching. In addition, the impeller and motor are isolated from the housing by sealed bearings, effectively protecting the drive components from water erosion. The overall structure achieves a balance between precise fluid control and convenient maintenance through modular design, and is simpler and easier to operate compared to existing technologies.

[0041] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a pipe rotation and reversing installation structure.

[0042] like Figures 1-13 As shown, this utility model discloses a pipe rotation and reversing installation structure, including a housing 100, as follows: Figure 1 and Figure 4 As shown, the housing 100 has a water inlet 102 and a water outlet 101. The water inlet 102 and the water outlet 101 are respectively opened at the liquid inlet end and the liquid outlet end of the housing 100. They are used to introduce liquid into the housing 100 through the water inlet 102, and the liquid in the housing 100 is discharged through the water outlet 101. The water outlet 101 and the water outlet 101 are interconnected with the inner cavity of the housing 100 to form a liquid flow channel for liquid flow.

[0043] Specifically, the pipe rotation and direction-changing installation structure involved in this solution is assembled at the left and right ends of the pool cleaning machine. There are two sets of pipe rotation and direction-changing installation structures, which mainly use water as power. One of the two sets of pipe rotation and direction-changing installation structures is static and the other is dynamic, so as to drive the pool cleaning machine to move back and forth.

[0044] A grille assembly is provided inside the housing 100. The grille assembly is used to switch the flow direction of the liquid to adjust the traveling direction of the pool cleaning machine. The grille assembly includes a rotatable grille sleeve 500. Among them, the grille sleeve 500 is arranged on one side of the housing 100 close to the water outlet hole 101. Inside the inner cavity of the grille sleeve 500, a horizontal partition 530 is arranged in the vertical direction. The horizontal partition 530 is used to flexibly change the liquid flow direction. The horizontal partition 530 is installed inside the inner cavity of the grille sleeve 500 and rotates with the grille sleeve 500. The assembly angle of the horizontal partition 530 is adjusted by using the grille sleeve 500 to switch the liquid flow direction. At the same time, the vertical partition 520 is horizontally placed in the inner cavity of the grille sleeve 500, and the horizontal partition 530 and the vertical partition 520 are symmetrically connected at a right angle. Both the vertical partition 520 and the horizontal partition 530 are multiple.

[0045] It should be noted that the pool cleaning machine in the embodiment of this application uses the water body ejected through the water outlet hole 101 to provide thrust for forward and backward movement, and uses the horizontal partition 530 to change the flow of the water body to change the traveling direction of the pool cleaning machine.

[0049] When the grating sleeve 500 is inside the water channel outer pipe 300, the opposite end of the water channel inner pipe 200 and the water channel outer pipe 300 abuts against the end of the grating sleeve 500. After the fixing knob 700 is fitted onto the water channel outer pipe 300, the limiting abutment 710 provided on the right side of the fixing knob 700 can abut against the right side of the grating sleeve 500. In this way, the grating sleeve 500 can be movably installed inside the water channel outer pipe 300, so that it cannot be arbitrarily removed from the water channel outer pipe 300.

[0050] A fixing member 210 is provided below the inner water pipe 200. The fixing member 210 and the inner water pipe 200 are fastened together by bolts. The fixing member 210 is bolted to the inner wall of the housing 100. The fixing member 210 can be used to fix the inner water pipe 200. The auxiliary fastener 220 is fitted on the left side of the inner water pipe 200. The surface of the auxiliary fastener 220 is fixedly connected to the sealing partition 611 by screws. Therefore, the fixing member 210 and the auxiliary fastener 220 can be used to fix and install the inner water pipe 200.

[0051] Two sets of inserts 301 are symmetrically connected along the axis on the right side of the water channel outer pipe 300. In this scheme, it is preferred to set three inserts 301 in one set. Two baffles 400 are symmetrically arranged along the axis on the water channel outer pipe 300. The surfaces of the opposite ends of the two baffles 400 are provided with slots 401 that cooperate with the inserts 301. The slots 401 are inserted into the inner cavity of the inserts 301, and the baffles 400 are installed on the surface of the water channel outer pipe 300.

[0052] In this embodiment, after the fixing knob 700 is fitted onto the top of the grille sleeve 500, the limiting abutment 710 on the fixing knob 700 can abut against the surfaces of the grille sleeve 500 and the baffle 400 respectively, so that the grille sleeve 500 and the baffle 400 are both installed on the surface of the waterway outer pipe 300.

[0053] The baffle 400 is made of flexible silicone material and can be bent to a certain extent to open and close the opening of the outer water pipe 300 away from the inner water pipe 200.

[0054] In actual use, because the baffle 400 is made of flexible material, when the water entering the housing 100 passes through the inner pipe 200 and the outer pipe 300 and is discharged outward through the outlet hole 101, the water impacts the baffle 400, causing the baffle 400 to bend, thereby pressurizing the water and sending it outward.

[0055] When a user needs to adjust the horizontal baffle 530 to change the direction of water flow, their fingers can pass through the baffle 400 and directly flick the baffle 400, causing the baffle 400 to flip outward with the insertion position of the slot 401 and the insertion post 301 as the center point, and then the user can hold the horizontal baffle 530 and flip it.

[0056] As a further optimization of this solution, a pull ring can be connected to the end of the baffle 400 away from the water channel outer pipe 300. The pull ring can increase the contact area between the user's fingers and the baffle 400. When prying the baffle 400 outward, the baffle 400 can be pulled outward by pulling the pull ring.

[0057] A fixing knob 700 is fitted onto the outer surface of the water channel outer pipe 300. A limiting plate 710 is connected to the right side of the fixing knob 700. The limiting plate 710 is used to limit the grid sleeve 500 and the baffle 400. Multiple buckles 720 are provided on the left side of the fixing knob 700. After the fixing knob 700 is fitted onto the surface of the water channel outer pipe 300, the buckles 720 are tightly against the left side of the water channel outer pipe 300, while the limiting plate 710 is tightly against the right side of the water channel outer pipe 300. Therefore, the fixing knob 700 is movably snapped onto the outer surface of the water channel outer pipe 300. The aperture of the fixing knob 700 is larger than the aperture of the limiting plate 710, and there are two buckles 720 arranged symmetrically.

[0058] When adjusting the rotation of the grid sleeve 500, and to prevent the grid sleeve 500 from rotating arbitrarily, a positioning protrusion 510 is connected to one end of the outer surface of the grid sleeve 500. The top of the inner cavity of the water channel outer pipe 300 and the right side of the inner cavity are provided with groove 1 302 and groove 2 303 that cooperate with the positioning protrusion 510. When the positioning protrusion 510 is inserted into the groove 1 302, the horizontal partition 530 is placed vertically. When the positioning protrusion 510 is rotated to ninety degrees with the grid sleeve 500 and inserted into the groove 2 303, the horizontal partition 530 is placed horizontally, thereby changing the orientation of the horizontal partition 530.

[0059] In actual use, under the limitation of the positioning protrusion 510, the grid sleeve 500 cannot rotate freely. Only by applying external force can the grid sleeve 500 be moved.

[0060] The grooves 302 and 303 have the same cavity specifications and are symmetrically arranged at ninety degrees on the inner wall of the outer pipe 300. Meanwhile, the positioning protrusion 510 is made of rubber, which gives it a certain degree of toughness.

[0061] The inner cavity of the inner water pipe 200 of the water channel is provided with an impeller 600, and on one side of the impeller 600 away from the inner water pipe 200 of the water channel, there is a motor 610. The output shaft of the motor 610 is connected to the shaft end of the impeller 600, so as to drive the impeller 600 by using the motor 610. The fixed end of the motor 610 is provided with a sealing partition 611. The outer surface of the sealing partition 611 is fixedly connected to the inner wall of the housing 100 by bolts, and the fixed end of the motor 610 is fixedly installed on the surface of the sealing partition 611 by bolts. Therefore, the motor 610 is fixedly installed in the housing 100 through the sealing partition 611;

[0062] Among them, while the output shaft of the motor 610 penetrates through the sealing partition 611 and is connected to the shaft end of the impeller 600, it is connected through a sealing bearing at the connection between the sealing partition 611 and the motor 610. Therefore, the liquid entering the housing 100 through the water outlet hole 101 cannot come into contact with the motor 610, thereby protecting the motor 610 and preventing the motor 610 from being damaged.

[0063] The working principle of a pipeline rotation and direction conversion installation structure: After water flows into the inner cavity through the water inlet hole 102 of the housing 100, it is guided to the grid sleeve 500 through the water channel pipe group composed of the inner water pipe 200 of the water channel and the outer water pipe 300 of the water channel, and finally passes through the grid assembly and is discharged through the water outlet hole 101, driving the pool cleaning robot to move forward with the water body as the power. When changing the moving direction of the pool cleaning robot, by pinching the side of the vertical partition 520 and rotating it clockwise by 90°, the whole grid sleeve 500 is rotated, so that the horizontal partition 530 changes from the vertical state to the horizontal state, thereby changing the water flow direction.

[0064] The "convex" shape design of the integrated molding of the inner water pipe 200 of the water channel and the outer water pipe 300 of the water channel, combined with the fixing parts 210 and the auxiliary fixing parts 220, realizes rapid assembly; the grid sleeve 500 ensures the stability of the 90° rotation and switching through the limiting cooperation of the positioning protrusion 510 with the first groove 302 and the second groove 303;

[0065] The flexible baffle 400 is detachably connected to the slot 401 through the insertion post 301, and is automatically bent by the impact of water flow to spray out water; the fixing knob 700 forms a two-way limit on the grid sleeve 500 and the baffle 400 through the buckle 720 and the limiting abutting plate 710, avoiding the detachment of components. In addition, the impeller 600 and the motor 610 are isolated from the housing 100 through a sealing bearing, effectively protecting the driving components from being eroded by water flow. The overall structure realizes the unity of precise fluid control and convenient maintenance through modular design, and is simpler in structure and more convenient to operate compared with the prior art.
