Description

Technical Field

[0001] This invention relates to the field of pool cleaning equipment technology, specifically to a snorkeling device for a pool cleaning machine and a pool cleaning machine. Background Technology

[0002] Existing pool cleaning machines can be divided into three categories. The first type of pool cleaning machine can only clean underwater, the second type can only float on the water surface and can only clean the surface, and the third type of pool cleaning machine has a snorkeling function, which can clean both underwater and the surface. Its core feature is that it can achieve deeper cleaning through a snorkeling device.

[0003] Currently, there are three types of locations for the inlet and outlet water tanks of pool cleaners with snorkeling functions: the first is inside the casing of the pool cleaner, the second is inside the casing of the walking device on both sides of the pool cleaner, and the third is outside the casing of the pool cleaner.

[0004] In the first scenario, the drawback is the increased internal volume of the casing. If the casing size isn't increased, all other components inside must be rearranged and reduced in size. The filter box and sealing chamber often need to be smaller, leading to decreased filtration efficiency. A smaller sealing chamber necessitates smaller pump and motor units, affecting their models and functions. Other components will also be affected to varying degrees. If the volume of other components remains constant while increasing the casing size to accommodate water inlets and outlets, the entire pool cleaner becomes larger, making it less portable.

[0005] In the second scenario, the drawback is that it occupies the space inside the casing of the walking device. The inlet and outlet water tanks are placed in the middle of the walking device, but the intermediate transmission device cannot be placed. If the front and rear dimensions of the pool cleaner are large, the lack of an intermediate transmission device will lead to instability in the transmission process, which is not conducive to the smooth movement of the pool cleaner.

[0006] In the third scenario, the drawback is that it increases the walking resistance of the pool cleaner. Because the inlet and outlet water tanks are located outside the pool cleaner's casing, they increase water resistance as the pool cleaner moves, reducing walking speed, increasing energy consumption, and decreasing cleaning efficiency.

[0007] There is currently no snorkeling device that can both rearrange and function other components within the pool cleaner's casing, and also avoid affecting the transmission function of the walking mechanism, as well as the pool cleaner's walking speed and resistance.

[0008] How to improve the inlet and outlet water tanks of snorkeling devices so that they can efficiently complete the water flow in and out tasks required for snorkeling, and also be perfectly integrated into the overall structure of pool cleaning machines, achieving "seamless compatibility" with the three major elements of internal space, transmission system and fluid shape, is a technical problem that urgently needs to be solved by those skilled in the art.

[0009] Based on this, we propose snorkeling devices and pool cleaning machines. Summary of the Invention

[0010] The purpose of this invention is to overcome the above-mentioned problems existing in the prior art and to provide a snorkeling device for a pool cleaning machine and a pool cleaning machine. The pump performs water intake and exhaust and air intake and drainage for the roller brush cylinders one and two through pipe one, pipe two and intermediate pipe. This does not affect the rearrangement and function of other components inside the pool cleaning machine casing, nor does it affect the transmission function of the walking device, nor does it affect the walking speed and resistance of the pool cleaning machine.

[0011] To solve the above-mentioned technical problems, the present invention provides a snorkeling device for a swimming pool cleaning machine, including a first pipe, a first roller brush cylinder, an intermediate pipe, a second roller brush cylinder, a second pipe, and a pump. The first pipe, the first roller brush cylinder, the intermediate pipe, the second roller brush cylinder, and the second pipe are connected in sequence. The pump performs air intake and drainage and water intake and exhaust for the first roller brush cylinder and the second roller brush cylinder through the first pipe, the second pipe, and the intermediate pipe.

[0012] The snorkeling device of the pool cleaning machine includes an inner tube 1 and an inner tube 2 connected in the middle tube. Inner tube 1 includes an inner shaft pipe 1, and inner tube 2 includes an inner shaft pipe 2. One end of inner shaft pipe 1 and one end of inner shaft pipe 2 are connected. Pipe 1 includes an outer tube 1, and pipe 2 includes an outer tube 2. Outer tube 1 includes an outer shaft pipe 1, and outer tube 2 includes an outer shaft pipe 2. Both outer shaft pipe 1 and inner shaft pipe 1 are rotatably connected to roller brush cylinder 1, which can rotate around outer shaft pipe 1 and inner shaft pipe 1. Both outer shaft pipe 2 and inner shaft pipe 2 are rotatably connected to roller brush cylinder 2, which can rotate around outer shaft pipe 2 and inner shaft pipe 2. The axes of outer shaft pipe 1, inner shaft pipe 1, roller brush cylinder 1, outer shaft pipe 2, inner shaft pipe 2, and roller brush cylinder 2 are all on the same straight line.

[0013] The snorkeling device of the pool cleaning machine includes a pipe 1 and a pipe 2. One end of the pipe 1 is connected to the outer end of the outer shaft pipe 1, and the other end of the pipe 1 is connected to the pump. One end of the pipe 2 is connected to the outer end of the outer shaft pipe 2, and the other end of the pipe 2 is the water inlet and outlet. The device also includes a pipe 3, one end of which is connected to the pump, and the other end of which is the air inlet and outlet.

[0014] The snorkeling device of the pool cleaning machine includes an inner tube 1 comprising an inner inlet / outlet pipe 1, one end of which is an inner opening 1, and the other end of which is connected to the other end of an inner shaft pipe 1. An inner tube 2 comprises an inner inlet / outlet pipe 2, one end of which is an inner opening 2, and the other end of which is connected to the other end of an inner shaft pipe 2. An outer tube 1 comprises an outer inlet / outlet pipe 1, one end of which is an outer opening 1, and the other end of which is connected to the inner end 1 of an outer shaft pipe 1. An outer tube 2 comprises a connected outer shaft pipe. There are two pipes, one of which is an external opening and the other is connected to the inner end of the outer shaft pipe. When the pool cleaning machine is working, the roller brush cylinders one and two rotate, while the outer shaft pipe and the inner shaft pipe do not rotate. The roller brush cylinder one rotates around the outer shaft pipe and the inner shaft pipe, with the position of the external opening being higher than the position of the inner opening. Similarly, the outer shaft pipe and the inner shaft pipe do not rotate, while the roller brush cylinder two rotates around the outer shaft pipe and the inner shaft pipe, with the position of the inner opening being higher than the position of the external opening.

[0015] The snorkeling device of the pool cleaning machine has an outer counterweight on the outer tube 1. When the roller brush 1 rotates, the outer tube 1 remains stationary under the action of the outer counterweight. The inner tube 1 has an inner counterweight on the inner tube 1. When the roller brush 1 rotates, the inner tube 1 remains stationary under the action of the inner counterweight. The outer tube 2 has an outer counterweight on the outer tube 2. When the roller brush 2 rotates, the outer tube 2 remains stationary under the action of the outer counterweight. The inner tube 2 has an inner counterweight on the inner tube 2. When the roller brush 2 rotates, the inner tube 2 remains stationary under the action of the inner counterweight.

[0016] The snorkeling device of the pool cleaning machine includes an outer tube 1 comprising a counterweight mounting tube 1, which is located on both sides of the outer shaft pipe 1, with the side of the counterweight mounting tube 1 away from the outer inlet / outlet pipe 1 being closed. The outer counterweight 1 is mounted on the counterweight mounting tube 1. The inner tube 2 includes a counterweight mounting tube 2, which is located on both sides of the inner shaft pipe 2, with the side of the counterweight mounting tube 2 away from the inner inlet / outlet pipe 2 being closed. The inner counterweight 2 is mounted on the counterweight mounting tube 2. The inner counterweight 1 is mounted on the inner inlet / outlet pipe 1, and the outer counterweight 2 is mounted on the outer inlet / outlet pipe 2.

[0017] The snorkeling device of the pool cleaner has the following functions when the pool cleaner is working: under the action of the outer counterweight one, when the roller brush one rotates, the outer opening one faces upward and is close to the inner wall one of the roller brush one; under the action of the inner counterweight one, when the roller brush one rotates, the inner opening one faces downward and is close to the inner wall one of the roller brush one; under the action of the outer counterweight two, when the roller brush two rotates, the inner opening two faces upward and is close to the inner wall two of the roller brush two; under the action of the inner counterweight two, when the roller brush two rotates, the outer opening two faces downward and is close to the inner wall two of the roller brush two.

[0018] The snorkeling device of the pool cleaning machine includes a roller brush cylinder 1 comprising an outer support component 1, an inner support component 1, and a cylinder 1. The outer support component 1 and the inner support component 1 are fixedly and sealed at both ends of the cylinder 1. An outer shaft pipe 1 passes through the outer shaft hole 1 of the outer support component 1 and forms a rotatable and sealed connection with the outer support component 1. An inner shaft pipe 1 passes through the inner shaft hole 1 of the inner support component 1 and forms a rotatable and sealed connection with the inner support component 1. The roller brush cylinder 2 comprises an outer support component 2, an inner support component 2, and a cylinder 2. The outer support component 2 and the inner support component 2 are fixedly and sealed at both ends of the cylinder 2. The outer shaft pipe 2 passes through the outer shaft hole 2 of the outer support component 2 and forms a rotatable and sealed connection with the outer support component 2. The inner shaft pipe 2 passes through the inner shaft hole 2 of the inner support component 2 and forms a rotatable and sealed connection with the inner support component 2.

[0019] Pool cleaning machine, including the snorkeling device for the pool cleaning machine in front.

[0020] The pool cleaning machine has two sets of snorkeling devices. One set of snorkeling devices has roller brush cylinder one and roller brush cylinder two installed on one side of the pool cleaning machine casing, and the other set of snorkeling devices has roller brush cylinder one and roller brush cylinder two installed on the other side of the casing. Each set of snorkeling devices has pipe one, intermediate pipe, pipe two and pump installed inside the casing.

[0021] In summary, the present invention has at least one of the following beneficial effects:

[0022] This invention discloses a snorkeling device for a pool cleaning machine, comprising a first pipe, a first roller brush cylinder, an intermediate pipe, a second roller brush cylinder, a second pipe, and a pump. The first pipe, the first roller brush cylinder, the intermediate pipe, the second roller brush cylinder, and the second pipe are sequentially connected. The pump, through the first pipe, the second pipe, and the intermediate pipe, performs air intake and drainage, as well as water intake and exhaust, for the first and second roller brush cylinders. This pump's operation of water intake and exhaust, as well as air intake and drainage, for the first and second roller brush cylinders does not affect the rearrangement or function of other components within the pool cleaning machine's casing, nor does it affect the transmission function of the walking mechanism, or the walking speed and resistance of the pool cleaning machine.

[0023] This invention innovatively integrates the core components of the snorkeling function—roller brush cylinder 1 and roller brush cylinder 2—externally, making them also serve as wheels. The roller brush cylinders themselves function as the snorkeling chamber, and the fixed inlet / outlet water pipes—the outer and inner shaft pipes—serve as the rotation axis. This allows the gears driven by the transmission motor to directly drive the roller brush cylinders, resulting in a direct and stable transmission path. This eliminates the transmission instability issues caused by placing a water tank in the middle, thus solving the problem of "affecting transmission stability." Furthermore, it significantly frees up internal space, resolving the problem of "internal space encroachment." In this invention, the external "inlet / outlet water chamber" is cleverly integrated with the walking roller brush, without adding any extra, non-functional external protrusions. This generates almost no additional water flow resistance, perfectly avoiding the problems of speed reduction and increased energy consumption. It solves the problem of increased resistance caused by traditional external inlet / outlet water chamber designs, fundamentally resolving the integration contradictions between snorkeling devices and pool cleaning machines in terms of spatial layout, transmission structure, and fluid shape.

[0024] The snorkeling device of the pool cleaner of this invention, by designing the roller brush cylinder as a sealed chamber that can be filled and drained, simultaneously undertakes three major functions: walking, cleaning (brushing), and snorkeling (providing buoyancy). It is a highly integrated design that greatly improves space utilization efficiency. The entire snorkeling system does not disrupt the original hydrodynamic shape of the cleaner, maintaining a low flow resistance shape and high efficiency. Through the coordinated work of pumps, pipes, and counterweights, intelligent water intake and exhaust (diving) and air intake and exhaust (surfacing) are achieved, realizing efficient snorkeling function. This invention, through the innovative design concept of "functional integration," combines the snorkeling chamber and the walking roller brush into one, supplemented by a clever piping system that uses a rotating axis for filling and draining. It successfully and perfectly realizes the snorkeling function of the pool cleaner without introducing any new contradictions. Ultimately, it achieves a high-performance pool cleaner with compact structure, stable movement, low resistance, low energy consumption, powerful functions, and reliable snorkeling capability.

[0054] The following is in conjunction with the appendix Figures 1-12 The present invention will be described in further detail below.

[0055] One embodiment of the present invention is shown in the appendix. Figure 1 ~Attached Figure 12 The snorkeling device of the pool cleaning machine includes pipe 1, roller brush cylinder 1 2, intermediate pipe, roller brush cylinder 2 3, pipe 2 and pump 1. Pipe 1, roller brush cylinder 1 2, intermediate pipe, roller brush cylinder 2 3 and pipe 2 are connected in sequence. Pump 1 uses pipe 1, pipe 2 and intermediate pipe to supply air and water to roller brush cylinder 1 2 and roller brush cylinder 2 3 for air intake and drainage and water intake and exhaust.

[0056] Such a snorkeling device does not affect the rearrangement and function of other components inside the pool cleaner's casing, nor does it affect the transmission function of the walking device, nor does it affect the walking speed and resistance of the pool cleaner.

[0057] When the pool cleaner needs to be submerged underwater, pump 1 uses pipes 1, 2 and the intermediate pipe to intake and exhaust water from roller brush cylinders 2 and 3. During this process, the pool cleaner gradually becomes heavier. When the pool cleaner is heavy enough, it submerges underwater.

[0058] When the pool cleaner needs to float to the surface, pump 1 uses pipes 1, 2 and intermediate pipe to supply air and drain the roller brush cylinders 2 and 3. During this process, the pool cleaner gradually becomes lighter. When the pool cleaner is light enough, it floats to the surface.

[0059] The term "connection" as used in this application includes both integrally formed connections and connections formed separately and then connected together.

[0060] The snorkeling device of the pool cleaner includes an inner tube 6 and an inner tube 8 connected in the middle. Inner tube 6 includes an inner shaft pipe 601, and inner tube 8 includes an inner shaft pipe 801. One end of inner shaft pipe 601 and one end of inner shaft pipe 801 are connected. Pipe 1 includes an outer tube 5, and pipe 2 includes an outer tube 7. Outer tube 5 includes an outer shaft pipe 501, and outer tube 7 includes an outer shaft pipe 701. Both outer shaft pipe 501 and inner shaft pipe 601 form a connection with the roller brush cylinder 2. The roller brush cylinder 2 is rotatably connected to the outer shaft tube 501 and the inner shaft tube 601. The outer shaft tube 701 and the inner shaft tube 801 are rotatably connected to the roller brush cylinder 3. The roller brush cylinder 3 is rotatably connected to the outer shaft tube 701 and the inner shaft tube 801. The axes of the outer shaft tube 501, the inner shaft tube 601, the roller brush cylinder 2, the outer shaft tube 701, the inner shaft tube 801, and the roller brush cylinder 3 are all on the same straight line.

[0061] The outer shaft pipe 501 will not rotate with the rotation of the roller brush cylinder 2, so the outer pipe 5 will not be screwed tight or damaged due to the rotation of the roller brush cylinder 2 and will not be unable to be used for air or water inlet / outlet. Therefore, the pipe 6 will not be screwed tight or damaged due to the rotation of the roller brush cylinder 2 and will not be unable to be used for air or water inlet / outlet.

[0062] The outer shaft pipe 701 will not rotate with the rotation of the roller brush cylinder 3, so the outer pipe 7 will not be screwed tight or damaged due to the rotation of the roller brush cylinder 3, thus preventing it from being used for air or water inlet / outlet. Similarly, the inner pipe 8 will not be screwed tight or damaged due to the rotation of the roller brush cylinder 3, thus preventing it from being used for air or water inlet / outlet.

[0063] The inner shaft tube 601 will not rotate with the rotation of the brush cylinder 2, and the inner shaft tube 801 will not rotate with the rotation of the brush cylinder 3. Therefore, there is no relative movement between the inner tube 6 and the inner tube 8. The connecting part between the inner tube 6 and the inner tube 8 will not be screwed tight or damaged and will not be used to allow air or water to enter or exit. The intermediate tube will also not be screwed tight or damaged and will not be used to allow air or water to enter or exit.

[0064] This ensures that while the first and second roller brush cylinders rotate, the pump 1 can smoothly supply air and water to the first and second roller brush cylinders 2 and 3 through pipes 1, 2, and the intermediate pipe.

[0065] The snorkeling device of the pool cleaning machine includes a pipe 1 (pipe 10) and a pipe 2 (pipe 2 11). One end of pipe 10 is connected to the outer end of the outer shaft pipe 501, and the other end of pipe 10 is connected to the pump 1. One end of pipe 2 11 is connected to the outer end of the outer shaft pipe 701, and the other end of pipe 2 11 is a water inlet / outlet end 1101. The device also includes a pipe 3 (pipe 9), one end of which is connected to the pump 1, and the other end of which is an air inlet / outlet end 901.

[0066] When the pool cleaner needs to be submerged, the water intake and exhaust process is as follows: Pump 1 operates, drawing water into the inlet / outlet 1101. The water then flows sequentially through pipe 11, outer pipe 7, roller brush cylinder 3, inner pipe 8, inner pipe 6, and roller brush cylinder 2. During this process, water enters roller brush cylinders 2 and 3. Simultaneously, some or all of the air in roller brush cylinders 2 and 3 is compressed by the water and flows sequentially through outer pipe 5, pipe 10, pump 1, and pipe 9, finally exiting from the air intake / outlet 901. As the pool cleaner gradually becomes heavier, it submerges when sufficiently heavy. If roller brush cylinders 2 and 3 are full, water can continue to flow sequentially through outer pipe 5, pipe 10, pump 1, and pipe 9, exiting from the air intake / outlet 901. This prevents roller brush cylinders 2 and 3 from expanding or even exploding due to excessive water pressure.

[0067] When the pool cleaner needs to float to the surface, the air intake and drainage process is as follows: Pump 1 operates, drawing air into the air intake / exhaust end 901. The air then sequentially passes through pipe 3 (9), pump 1, pipe 1 (10), outer pipe 1 (5), roller brush cylinder 1 (2), inner pipe 1 (6), inner pipe 2 (8), and roller brush cylinder 2 (3). During this process, air enters roller brush cylinders 1 (2) and 2 (3). Simultaneously, some or all of the water in roller brush cylinders 1 (2) and 2 (3) is compressed by the air and flows sequentially through outer pipe 2 (7) and pipe 2 (11), finally flowing out from the water intake / exhaust end 1101. During this process, the pool cleaner gradually becomes lighter, and when it is sufficiently light, it floats to the surface. If roller brush cylinders 1 (2) and 2 (3) are full of air, more air can flow sequentially through outer pipe 2 (7) and pipe 2 (11) and be ejected from the water intake / exhaust end 1101. This prevents roller brush cylinders 1 (2) and 2 (3) from expanding or even exploding due to excessive air pressure.

[0068] The snorkeling device of the pool cleaning machine includes an inner tube 6 comprising an inner inlet / outlet pipe 602, one end of which is an inner opening 6021, and the other end of which is connected to the other end of an inner shaft pipe 601. An inner tube 8 comprises an inner inlet / outlet pipe 802, one end of which is an inner opening 8021, and the other end of which is connected to the other end of an inner shaft pipe 801. An outer tube 5 comprises an outer inlet / outlet pipe 502, one end of which is an outer opening 5021, and the other end of which is connected to the inner end of an outer shaft pipe 501. An outer tube 7 comprises a connected outer shaft pipe 701 and... The external inlet / outlet pipe 2 702 has an external opening 7021 at one end and is connected to the inner end 2 of the external shaft pipe 2 701 at the other end. When the pool cleaning machine is working, the roller brush cylinder 1 2 and the roller brush cylinder 2 3 rotate, while the external shaft pipe 1 501 and the inner shaft pipe 1 601 do not rotate. The roller brush cylinder 1 2 rotates around the external shaft pipe 1 501 and the inner shaft pipe 1 601. The position of the external opening 1 5021 is higher than the position of the inner opening 1 6021. The external shaft pipe 2 701 and the inner shaft pipe 2 801 do not rotate, while the roller brush cylinder 2 3 rotates around the external shaft pipe 2 701 and the inner shaft pipe 2 801. The position of the inner opening 2 8021 is higher than the position of the external opening 2 7021.

[0069] In this way, the roller brush tubes 2 and 3 of the snorkeling device can more easily take in water and vent air, and take in air and drain water. The following describes the two processes of taking in water and venting air, and taking in air and draining water in detail.

[0070] Specifically, the water intake and exhaust process is as follows: When the pool cleaner needs to be submerged, pump 1 operates. Under the action of pump 1, water is drawn in from the inlet / outlet end 1101. Then, the water sequentially passes through pipe 2 11, outer pipe 2 7, roller brush cylinder 2 3, inner pipe 2 8, inner pipe 1 6, and roller brush cylinder 1 2. During this process, water enters roller brush cylinder 2 3 and roller brush cylinder 1 2 sequentially. Since the density of water is greater than that of air, when water enters roller brush cylinder 2 3, it accumulates from bottom to top. The air in roller brush cylinder 2 3 is compressed upwards by the water. Because the position of inner opening 2 8021 is higher than that of outer opening 2 7021, the air in roller brush cylinder 2 3 will not be trapped by water and thus unable to enter inner opening 2 8021. Instead, it easily enters inner inlet / outlet pipe 2 802 from the higher inner opening 2 8021, then sequentially passes through inner shaft pipe 2 801, inner shaft pipe 1 601, and inner inlet / outlet pipe 1 602, exiting from inner opening 1 602. 21 flows into the first roller brush cylinder 2. At the same time, as the air pressure in the second roller brush cylinder 3 decreases, water can more easily enter the second roller brush cylinder 3 from the outer opening 7021. The water is below the air. As more and more water rises in the second roller brush cylinder 3, the water level reaches the inner opening 8021 of the inner inlet / outlet pipe 802. The water then enters the inner inlet / outlet pipe 802 from the inner opening 8021, and then passes through the inner shaft pipe 801, the inner shaft pipe 601, and the inner inlet / outlet pipe 602 in sequence, finally reaching the first roller brush cylinder 2 from the inner opening 6021. Because the outer opening 5021 is positioned higher than the inner opening 6021, the air in the roller brush cylinder 2 will not be trapped by water and thus unable to enter the outer opening 5021. Instead, it will be easily squeezed by the water into the outer opening 5021, and then exit through the outer inlet / outlet pipe 502 to reach pipe 9. It will then pass through pump 1 and pipe 10 in sequence, and finally the air will enter the atmosphere from the air inlet / outlet end 901. At the same time, because the air pressure in the roller brush cylinder 2 is decreasing, water can more easily enter the roller brush cylinder 2 from the inner opening 6021, and the amount of water in the roller brush cylinder 2 will increase.

[0071] Specifically, the air intake and drainage process is as follows: When the pool cleaner needs to float to the surface, pump 1 operates. Under the action of pump 1, air is drawn in from the air intake / exhaust end 901, and then sequentially passes through pipe 3 9, pump 1, pipe 1 10, outer pipe 1 5, roller brush cylinder 1 2, inner pipe 1 6, inner pipe 2 8, and roller brush cylinder 2 3. During this process, air enters roller brush cylinder 1 2 and roller brush cylinder 2 3 sequentially. When air enters roller brush cylinder 1 2, because the position of the outer opening 5021 is higher than... The inner opening 6021 is positioned so that air can more easily enter the roller brush cylinder 2 from the outer opening 5021. Since the density of water is greater than that of air, the air accumulates from top to bottom, and the water in the roller brush cylinder 2 is easily squeezed to the bottom by the air. The water enters the inner inlet / outlet pipe 602 from the lower inner opening 6021, and then passes through the inner shaft pipe 601, the inner shaft pipe 801, and the inner inlet / outlet pipe 802 in sequence, and finally enters the roller brush cylinder 3 from the inner inlet / outlet pipe 802.

[0072] Water is denser than air, and air rises above water. As more and more air accumulates in the roller brush cylinder 3 from top to bottom, reaching its lowest point at the inner opening 6021 of the inner inlet / outlet pipe 602, the air enters the inner inlet / outlet pipe 602 through the inner opening 6021, then passes sequentially through the inner shaft pipe 601, the inner shaft pipe 801, and the inner inlet / outlet pipe 802, finally reaching the roller brush cylinder 3 through the inner opening 8021. Because the inner opening 8021 is higher than the outer opening 7021, air can more easily enter the roller brush cylinder 3 from the inner opening 8021. As the air accumulates in the roller brush cylinder 3, water is forced to the outer opening 7021 by the air, then exits through the outer inlet / outlet pipe 702 into pipe 11, and finally enters the swimming pool from the inlet / outlet end 1101.

[0073] The snorkeling device of the pool cleaning machine has an outer counterweight 503 on the outer tube 5. When the roller brush cylinder 2 rotates, the outer tube 5 remains stationary under the action of the outer counterweight 503. The inner tube 6 has an inner counterweight 603 on the inner tube. When the roller brush cylinder 2 rotates, the inner tube 6 remains stationary under the action of the inner counterweight 603. The outer tube 7 has an outer counterweight 703 on the outer tube. When the roller brush cylinder 3 rotates, the outer tube 7 remains stationary under the action of the outer counterweight 703. The inner tube 8 has an inner counterweight 803 on the inner tube. When the roller brush cylinder 3 rotates, the inner tube 8 remains stationary under the action of the inner counterweight 803.

[0074] In this way, when the brush roller 2 rotates, the outer shaft tube 501 and the inner shaft tube 601 remain stationary. This prevents the friction between the brush roller 2 and the outer shaft tube 501 and the inner shaft tube 601 from rotating when the brush roller 2 rotates.

[0075] When the roller brush cylinder 2 3 rotates, the outer shaft tube 2 701 and the inner shaft tube 2 801 remain stationary. This prevents the roller brush cylinder 2 3 from rotating, thus eliminating the friction between it and the outer shaft tube 2 701 and the inner shaft tube 2 801.

[0076] At the same time, this further ensures that there is no relative movement between inner shaft pipe 1 601 and inner shaft pipe 2 801, and further ensures that the position of outer opening 1 5021 is higher than the position of inner opening 1 6021, and the position of inner opening 2 8021 is higher than the position of outer opening 2 7021.

[0077] The snorkeling device of the pool cleaning machine includes an outer tube 5 comprising a counterweight mounting tube 504, which is located on both sides of the outer shaft tube 501, with the side of the counterweight mounting tube 504 away from the outer inlet / outlet tube 502 being closed. An outer counterweight 503 is mounted on the counterweight mounting tube 504. The inner tube 8 comprises a counterweight mounting tube 804, which is located on both sides of the inner shaft tube 801, with the side of the counterweight mounting tube 804 away from the inner inlet / outlet tube 802 being closed. An inner counterweight 803 is mounted on the counterweight mounting tube 804. An inner counterweight 603 is mounted on the inner inlet / outlet tube 602. An outer counterweight 703 is mounted on the outer inlet / outlet tube 702. Preferably, the counterweight mounting tube 1 (504) and the counterweight mounting tube 2 (804) are solid.

[0078] The snorkeling device of the pool cleaner operates as follows: Under the action of the outer counterweight 503, when the roller brush cylinder 2 rotates, the outer opening 5021 faces upward and is close to the inner wall of the roller brush cylinder 2. Under the action of the inner counterweight 603, when the roller brush cylinder 2 rotates, the inner opening 6021 faces downward and is close to the inner wall of the roller brush cylinder 2. Under the action of the outer counterweight 703, when the roller brush cylinder 2 rotates, the inner opening 8021 faces upward and is close to the inner wall of the roller brush cylinder 2. Under the action of the inner counterweight 803, when the roller brush cylinder 2 rotates, the outer opening 7021 faces downward and is close to the inner wall of the roller brush cylinder 2. Because water is denser than air, water sinks and air rises, thus further improving the efficiency of water intake and air exhaust, as well as the efficiency of air intake and air exhaust.

[0079] In this invention, a pump injects water into the roller brush cylinder through a pipe, while air is discharged from the other side, increasing weight and negative buoyancy to achieve submersion. Conversely, a pump injects air into the roller brush cylinder, while water is discharged from the other side, reducing weight and increasing positive buoyancy to achieve buoyancy. A counterweight ensures that the water inlet and water / air outlet remain in the correct orientation (one facing up, one facing down) as the roller brush cylinder rotates, thereby ensuring the continuity and high efficiency of the filling and draining process, and ultimately achieving a stable and efficient snorkeling function.

[0080] The snorkeling device of the pool cleaner includes a roller brush cylinder 2 comprising an outer support 201, an inner support 202, and a cylinder 203. The outer support 201 and inner support 202 are fixedly and sealed at both ends of the cylinder 203. An outer shaft pipe 501 passes through the outer shaft hole of the outer support 201 and forms a rotatable sealed connection with the outer support 201. An inner shaft pipe 601 passes through the inner shaft hole of the inner support 202 and forms a rotatable sealed connection with the inner support 202. A second roller brush cylinder 3 comprises an outer support 301, an inner support 302, and a cylinder 303.

[0081] The outer support member 2 301 and the inner support member 2 302 are fixedly and sealed at both ends of the cylindrical member 2 303. The outer shaft pipe 2 701 passes through the outer shaft hole 2 of the outer support member 2 301 and forms a rotatable sealed connection with the outer support member 2 301. The inner shaft pipe 2 801 passes through the inner shaft hole 2 of the inner support member 2 302 and forms a rotatable sealed connection with the inner support member 2 302.

[0082] In this way, both ends of cylinder 1 (203) and cylinder 2 (303) are sealed to prevent water leakage during water intake and exhaust, and to prevent air leakage during air intake and drainage, thus improving the efficiency of water intake and exhaust and the effect of air intake and drainage.

[0083] Specifically, the outer support member 201 includes an outer end cap 2011, the outer side of which is threadedly and sealed to the outer side of the cylindrical member 203.

[0084] The inner support component 202 includes an inner end cap 2021, the outer side of which is threadedly and sealed to the outer side of the cylindrical component 203.

[0085] The outer support member 301 includes an outer end cap 3011, the outer side of which is threadedly and sealed to the outer side of the cylindrical member 303.

[0086] The inner support component 302 includes an inner end cap 3021, and the outer side of the inner end cap 3021 is threadedly and sealed to the cylindrical component 303.

[0087] The outer support component 201 includes an outer oil seal 2012, which is mounted on the outer end cover 2011. The outer shaft pipe 501 passes through the outer end cover 2011 and the outer oil seal 2012, forming a rotatable sealed connection between the outer shaft pipe 501 and the outer oil seal 2012.

[0088] The inner support component 202 includes an inner oil seal 2022, which is mounted on the inner end cover 2021. An inner shaft pipe 601 passes through the inner end cover 2021 and the inner oil seal 2022, forming a rotatable sealed connection between the inner shaft pipe 601 and the inner oil seal 2022.

[0089] The second outer support component 301 includes a second outer oil seal 3012, which is mounted on the second outer end cover 3011. The second outer shaft pipe 701 passes through the second outer end cover 3011 and the second outer oil seal 3012, forming a rotatable sealed connection between the second outer shaft pipe 701 and the second outer oil seal 3012.

[0090] The inner support component 2 302 includes an inner oil seal 2 3022, which is mounted on the inner end cover 2 3021. The inner shaft pipe 2 801 passes through the inner end cover 2 3021 and the inner oil seal 2 3022, forming a rotatable sealed connection between the inner shaft pipe 2 801 and the inner oil seal 2 3022.

[0091] Preferably, the outer side of the outer end cap 2011 and the cylindrical part 203 are reinforced with adhesive to enhance the seal.

[0092] Preferably, the outer side of the inner end cap 2021 and the cylindrical part 203 are reinforced with adhesive to enhance the seal.

The pipe 1, intermediate pipe, pipe 2 and pump 1 of each snorkeling device are installed inside the housing 4.

[0097] When the pool cleaner needs to be submerged, both of its buoyancy devices simultaneously take in water and release air. This not only speeds up the descent but also prevents the pool cleaner from tipping over, ensuring it sinks safely into the water.

[0098] When the pool cleaner needs to float to the surface, its two snorkeling devices simultaneously take in air and drain water. This not only speeds up the process of surfacing but also prevents the pool cleaner from tipping over, ensuring it floats steadily to the surface.

[0099] When the pool cleaner tilts to one side on the water, you can control the air intake of the other side's roller brush cylinders 1 and 2 to be more, or control the air intake of the roller brush cylinders 1 and 2 to be less during the next air intake and drainage process. This can maintain the balance of the pool cleaner on the water surface.

[0100] When the pool cleaner tilts up on one side of the bottom, you can control the roller brush cylinder 12 and roller brush cylinder 23 on the tilted side to take in more water, or control the roller brush cylinder 12 and roller brush cylinder 23 on the other side to take in less water during the next water intake and air exhaust process. This can maintain the balance of the pool cleaner on the bottom of the water.

[0101] Preferably, the air inlet and outlet ends 901 of the two snorkeling devices are connected to a common air inlet and outlet channel 12, and the air inlet and outlet pipe is located on the side wall of the housing 4.
