Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pool cleaners, in particular to a water jet channel and pool cleaner capable of preventing steering failure. BACKGROUND

[0002] In existing pool cleaners, whether they are equipped with centrifugal pumps or axial flow pumps, in order to clean the pool comprehensively and expand the cleaning area, a first guide plate is often arranged in the drainage flow channel of the pool cleaner. The first guide plate is rotationally connected in the drainage flow channel. The water flow passes through the water inlet flow channel and then enters the drainage flow channel. When the pool cleaner needs to turn and walk, after the first guide plate is rotated, the first included angle one and the second included angle one between the first guide plate and the water flow cross section in the drainage flow channel are an acute angle and an obtuse angle respectively, and the sum of the first included angle one and the second included angle one is 180 degrees. The water flow will be guided by the first guide plate in the drainage flow channel to flow obliquely to one side of the pool cleaner, i.e. the water flow from the space between the first guide plate and the first included angle one with an acute angle, and then flows obliquely to one side of the pool cleaner and out of the pool cleaner, so that the pool cleaner turns and walks to expand the cleaning area, such as turning and walking in the shape of "Z". This steering walking technology is used in pool cleaners equipped with centrifugal pumps and axial flow pumps.

[0003] For example, a pool cleaner capable of reversing disclosed in Chinese Patent No. CN219196871U can make a small-angle turning, quickly turn around, and efficiently clean the pool. A pool cleaning robot with a reversing adjustment function disclosed in Chinese Patent No. CN217631557U has a reversing adjustment mechanism, which can adjust the drainage direction and change the movement direction of the pool cleaning robot, thereby reducing the probability of repeated cleaning routes and improving the cleaning efficiency of the pool cleaning robot. A pool robot with controllable steering disclosed in Chinese Patent No. CN217624043U can set the steering of the pool robot by manually adjusting the direction of the baffle or presetting the direction of the baffle, thereby controlling the direction of the pool robot.

[0004] However, the above-mentioned pool cleaners have a problem. Whether they are equipped with centrifugal pumps or axial flow pumps, steering failure often occurs, i.e. the steering angle of the pool cleaner is extremely small or even zero. The extremely small steering angle of the pool cleaner will lengthen the time for cleaning the pool comprehensively, and the zero steering angle of the pool cleaner will result in straight walking even for a long time, which cannot clean the pool comprehensively. Based on this, we propose a water jet channel and pool cleaner capable of preventing steering failure. SUMMARY

[0005] The present application aims at overcoming the above-mentioned problems existing in the prior art, and provides a water jet channel and a swimming pool cleaning machine capable of preventing steering failure, facilitating the steering walking of the swimming pool cleaning machine, preventing steering failure, optimizing the steering function, and improving the ability of the swimming pool cleaning machine to clean the swimming pool.

[0072] The above description is combined with the accompanying drawings Figures 1-45 The application is further described in detail.

[0073] Example one, refer to Figures 4-29 In order to solve the problem of steering failure of the existing pool cleaner with a centrifugal pump or a pool cleaner with an axial flow pump, the application discloses a water spraying channel capable of preventing steering failure, which comprises a drainage flow channel 4 and a steering device, the steering device comprises a first guide plate 9 which is rotationally connected to the drainage flow channel 4, the drainage flow channel 4 comprises an upper water outlet plate 5, a left water outlet plate 7, a lower water outlet plate 6 and a right water outlet plate 8 which are sequentially connected, and the steering device further comprises a first blocking strip 10, the lower water outlet plate 6 is an outwardly convex arc surface, and the first blocking strip 10 is connected to the lower water outlet plate 6; when the pool cleaner needs to be turned and walked, the first guide plate 9 is rotated, so that the first included angle one A and the second included angle one B of the flow cross section of the water flow in the drainage flow channel 4 are an acute angle and an obtuse angle respectively, a side surface of the first guide plate 9 facing the lower water outlet plate 6 is a first lower side 16, a side surface of the first blocking strip 10 facing the upper water outlet plate 5 is a first upper side 15, and the first lower side 16 of the first guide plate 9 and the first upper side 15 of the first blocking strip 10 are mutually attached or mutually close.

[0074] The turning failure is because of the distance between the first lower side 16 of the first guide plate 9 and the lower water outlet plate 6, a part of water flow will flow out from the space between the first guide plate 9 and the second included angle B of the flow section E, which is not blocked by the first guide plate 9, and does not flow out from the space between the first guide plate 9 and the first included angle A of the flow section E, and does not flow out obliquely to one side of the pool cleaner, but flows out to the rear direction of the forward direction of the pool cleaner, which does not play a role in promoting the turning of the pool cleaner. The distance between the first lower side 16 of the first guide plate 9 and the lower water outlet plate 6 is because the lower water outlet plate 6 is an outwardly convex arc surface. In order to make the water flow channel 4 have small resistance to water flow, the lower water outlet plate 6 of the water flow channel 4 needs to be designed as an outwardly convex arc surface, so that the lower water outlet plate 6 is streamlined, reducing the flow loss of water flow. However, the outwardly convex arc surface of the lower water outlet plate 6 causes the distance between the first lower side 16 of the first guide plate 9 and the lower water outlet plate 6. Therefore, the first guide plate 9 is connected to the first blocking strip 10 on the lower water outlet plate 6, and the first lower side 16 of the first guide plate 9 and the first upper side 15 of the first blocking strip 10 are close to each other or abut against each other, thereby preventing turning failure.

[0075] Referring to Figure 4 , Figure 6 , Figure 11 , Figure 25 , the upper end side and the lower end side of the first guide plate 9 are respectively provided with a first rotating shaft 17; two first shaft holes 18 are formed on the water flow channel 4, one of which is formed on the upper water outlet plate 5 and corresponds to the first rotating shaft 17 at the upper end of the first guide plate 9, and the other is located at the junction of the lower water outlet plate 6 and the right water outlet plate 8 and corresponds to the first rotating shaft 17 at the lower end side of the first guide plate 9; the first guide plate 9 is rotatably connected to the water flow channel 4 through the rotating cooperation of the first rotating shaft 17 and the first shaft hole 18, so that when the pool cleaner needs to turn and walk, the water flow flowing out from the space between the first guide plate 9 and the first included angle A of the flow section E is the most, which is most conducive to improving the turning function;

[0076] Referring to Figures 38-45 , when the pool cleaner needs to go straight, the first guide plate 9 is rotated so that the first guide plate 9 is perpendicular to the flow section E of the water flow in the water flow channel 4, and the first lower side 16 of the first guide plate 9 and the lower water outlet plate 6 abut against each other or are close to each other;

[0077] The first lower side 16 of the first guide plate 9 and the lower water outlet plate 6 are close to each other, which means that the distance between the first lower side 16 of the first guide plate 9 and the lower water outlet plate 6 is very small but there is still some gap, so as to avoid the friction between the first lower side 16 of the first guide plate 9 and the lower water outlet plate 6 being too large, which would cause the first guide plate 9 and the lower water outlet plate 6 to wear.

[0078] The first lower side 16 of the first guide plate 9 is in contact with the lower water outlet plate 6, meaning that the distance between the first lower side 16 of the first guide plate 9 and the lower water outlet plate 6 is zero, so as to prevent water flow from forming turbulence between the first lower side 16 of the first guide plate 9 and the lower water outlet plate 6.

[0079] See Figures 30-37 When the pool cleaning machine needs to turn and move, the first guide plate 9 is rotated so that the first angle A and the second angle B between the first guide plate 9 and the flow section E of the water flow in the drainage channel 4 are acute and obtuse, respectively. The first lower side 16 of the first guide plate 9 and the first upper side 15 of the first baffle 10 are in contact with each other or close to each other.

[0080] The first lower side 16 of the first guide plate 9 and the first upper side 15 of the first baffle 10 are close to each other, which means that the distance between the first lower side 16 of the first guide plate 9 and the first upper side 15 of the first baffle 10 is very small but there is still some gap. While properly preventing steering failure, this avoids excessive friction between the first lower side 16 of the first guide plate 9 and the first upper side 15 of the first baffle 10, which would cause wear on the first guide plate 9 and the first baffle 10.

[0081] The first lower side 16 of the first guide plate 9 and the first upper side 15 of the first baffle 10 are in contact with each other, meaning that the distance between the first lower side 16 of the first guide plate 9 and the first upper side 15 of the first baffle 10 is zero, so as to prevent water from flowing between the first lower side 16 of the first guide plate 9 and the first upper side 15 of the first baffle 10, and better prevent steering failure.

[0082] Therefore, the first lower side 16 of the first guide plate 9 and the first upper side 15 of the first baffle 10 are in contact with each other or close to each other. This reduces the water flow from the space between the first guide plate 9 and the flow section E at the second angle - B, which is obtuse. The water flow from the rear of the pool cleaning machine in the opposite direction of forward movement is also reduced. This increases the water flow from the space between the first guide plate 9 and the flow section E at the first angle - A, which is acute. This makes it easier for the water to flow obliquely to one side of the pool cleaning machine under the guidance of the first guide plate 9 in the drainage channel 4. This further facilitates the turning and walking of the pool cleaning machine, prevents steering failure, optimizes the steering function, and improves the ability of the pool cleaning machine to clean the pool comprehensively.

[0083] Thus, the pool cleaning machine has the functions of turning and straight walking, and the applicability of the pool cleaning machine is improved.

[0084] Embodiment two, with reference to Figures 25-29 Based on the embodiment one, the application provides another embodiment: the water spraying channel preventing turning failure, the turning device comprising a second guide plate 24, a second blocking strip 23 and a synchronizer 21, the second blocking strip 23 being connected to the lower water outlet plate 6, and the second guide plate 24 being rotatably connected to the water draining channel 4;

[0085] With reference to Figure 24 、 Figure 25 The side of the second guide plate 24 facing the lower water outlet plate 6 is a second lower side 11, and the side of the second blocking strip 23 facing the upper water outlet plate 5 is a first upper side 15.

[0086] With reference to Figures 4-8 The upper end side and the lower end side of the second guide plate 24 are each provided with a second rotating shaft 19; two second shaft holes 20 are formed on the water draining channel 4, one of which is formed on the upper water outlet plate 5 and corresponds to the second rotating shaft 19 at the upper end of the second guide plate 24, and the other corresponds to the second rotating shaft 19 at the lower end of the second guide plate 24, and the second rotating shaft 19 is rotatably connected to the second shaft hole 20, so that the second guide plate 24 is rotatably connected to the water draining channel 4.

[0087] With reference to Figure 25 The synchronizer 21 is connected to the first guide plate 9 and the second guide plate 24, the upper end of the first guide plate 9 is provided with a first synchronizer shaft 22, the upper end of the second guide plate 24 is provided with a second synchronizer shaft 25, one end of the synchronizer 21 is provided with a first synchronizer hole rotatably connected to the first synchronizer shaft 22, and the other end of the synchronizer 21 is provided with a second synchronizer hole rotatably connected to the second synchronizer shaft 25; the first synchronizer shaft 22 is rotatably connected to the first synchronizer hole, and the second synchronizer shaft 25 is rotatably connected to the second synchronizer hole, which is conducive to the synchronous movement of the first guide plate 9 and the second guide plate 24 under the linkage of the synchronizer 21, so as to ensure that the second guide plate 24 is always parallel to the first guide plate 9 (the real-time parallelism of the second guide plate 24 to the first guide plate 9 means that the second guide plate 24 is always parallel to the first guide plate 9 no matter whether the pool cleaning machine needs to walk straight, needs to turn, or the second guide plate 24 and the first guide plate 9 are in the process of rotation). The real-time parallelism of the second guide plate 24 to the first guide plate 9 avoids the out-of-sync movement of the first guide plate 9 and the second guide plate 24, which leads to the reduction of the water outlet flow. Thus, the water outlet flow of the water outlet 3 is ensured, and the cleaning efficiency of the pool cleaning machine is improved.

[0088] With reference to Figure 4 、 Figure 6 andFigure 25 The turning device further comprises an adjusting rod 26 fixed on the second guide plate 24 between the second rotating shaft 19 at the upper end of the second guide plate 24 and the second synchronous shaft 25. The top of the water drainage channel 4 is provided with an adjusting blind hole 27, and the adjusting rod 26 is rotationally connected in the adjusting blind hole 27. The adjusting blind hole 27 has a shape that the end holes on both sides are large and the channel in the middle is small. The outlet of the end hole is smaller than the diameter of the adjusting rod 26, and the inner diameter of the end hole and the width of the channel are larger than the diameter of the adjusting rod 26.

[0089] In this way, the adjusting rod 26 is clamped at both ends of the adjusting blind hole 27 and is not easy to loosen. When the second guide plate 24 needs to be turned, the second guide plate 24 is manually pushed. Since the inner diameter of the end hole and the width of the channel are larger than the diameter of the adjusting rod 26, the adjusting rod 26 comes out of the end hole on one side, passes through the channel in the middle, and then enters the end hole on the other side. When the second guide plate 24 is not pushed, since the outlet of the end hole is smaller than the diameter of the adjusting rod 26, the adjusting rod 26 is clamped in the two end holes and cannot come out, so the second guide plate 24 and the first guide plate 9 cannot be turned. In this way, the stability of turning and straight running is enhanced, and the first guide plate 9 and the second guide plate 24 are prevented from shaking to lose the turning effect and the straight running effect.

[0090] Referring to Figures 38-45 When the pool cleaner needs to run straight, the second guide plate 24 is turned so that the second guide plate 24 is perpendicular to the flow section E of the water flow in the water drainage channel 4, and the second lower side 11 of the second guide plate 24 is in close contact with or close to the lower water outlet plate 6.
