Description

Technical Field

[0001] This utility model belongs to the technical field of swimming pool cleaning devices, specifically relating to an automatic underwater sewage suction device for swimming pools. Background Technology

[0002] As recreational venues, the cleanliness of swimming pool water directly impacts users' experience and health. Traditional pool cleaning methods primarily rely on manual labor, which is not only inefficient and labor-intensive but also fails to achieve thorough cleaning. While some automatic pool cleaning systems are available, most suffer from poor suction, complex operation, and difficult maintenance. For example, in the public account "CN..." Chinese patent 212957842U discloses an underwater pool cleaning device. In use, the operator controls a cleaning machine that moves along the pool bottom via a conveyor belt. The cleaning system draws wastewater from the inlet pipe into the machine, trapping sludge, while the water is discharged from the outlet pipe. Depending on the pool depth, a counterweight is placed inside the mounting frame to increase the machine's weight, preventing it from floating and facilitating stable movement. A scraping mechanism removes sludge adhering to the pool bottom, and a sweeping mechanism cleans the remaining sludge, making it easier for the cleaning machine to absorb the sludge from the water. However, since pools are generally large, this device requires multiple back-and-forth movements to clean the pool bottom, resulting in high cleaning difficulty and low efficiency.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-8As shown, this utility model provides the following technical solution:

[0029] An automatic underwater sewage suction device for swimming pools includes two symmetrically arranged suction components 2, a foldable flexible connector 3 between the two suction components 2, and a negative pressure chamber connected between the two suction components 2 and the flexible connector 3. An suction hole for suctioning objects is formed between the bottom of the two suction components 2 and the flexible connector 3.

[0030] The underwater automatic sewage suction device for swimming pools also includes a storage component and a negative pressure component for extracting gas. The storage component forms a cavity for storing objects. The negative pressure component is fixed on the storage component, and the air inlet of the negative pressure component is connected to the cavity. A flexible air delivery component is connected between the air inlet of the storage component and the two suction components 2.

[0031] With the above technical solution, when personnel use the device to clean the bottom of the pool, malfunctions are inevitable during operation. In case of blockages or other abnormalities, there is often a lack of effective emergency response mechanisms, posing safety hazards to users. Therefore, personnel need to conduct regular emergency drills using the device. When personnel need to use the device, place the two suction components 2 at the bottom of the pool and pull them towards the sides of the pool wall. This causes the suction components 2 to stretch the flexible connector 3, expanding it until the suction components 2 touch the edge of the pool. Then, connect the traction rope to the suction components 2. The negative pressure component then extracts gas from the storage component, creating a negative pressure inside. This causes the flexible air delivery component on the storage component to generate suction, which in turn creates suction between the two suction components 2 and the flexible connector 3. The traction rope then pulls the two suction components 2 and the flexible connector 3, allowing them to move. As the two suction components 2 and the flexible connector 3 move, they absorb debris from the bottom of the pool, thus cleaning the pool bottom.

[0032] Specifically, in one embodiment, regarding the above-mentioned suction member 2:

[0033] like Figures 1-5 As shown, the suction component 2 includes a suction shell 21, the bottom of the suction shell 21 is open to form a negative pressure hole 22, and the interior of the suction shell 21 forms an inner cavity 23, which is connected to the negative pressure hole 22.

[0034] In this embodiment, when the suction component 2 and the flexible connector 3 move, the two suction shells 21 and the flexible connector 3 move synchronously. When the two suction shells 21 and the flexible connector 3 move, the flexible air delivery component draws in the gas inside the two suction shells 21 and the flexible connector 3, thereby generating suction at the bottom of the negative pressure hole 22. The negative pressure hole 22 absorbs the debris at the bottom of the pool, thereby cleaning the bottom of the pool.

[0035] In addition, in this utility model, to facilitate the movement of the suction shell 21 inside the swimming pool, such as... Figures 3-4 As shown, each of the two suction shells 21 is fixedly connected to a traction frame 17 for connecting the traction rope on one side adjacent to the flexible connector 3.

[0036] In this embodiment, when personnel need to move the suction shell 21, one end of the traction rope is tied to the traction frame 17 on the suction shell 21. By pulling the traction rope, the traction rope drives the suction shell 21 to move, thereby allowing the suction shell 21 to be cleaned at the bottom of the pool.

[0037] When the suction shell 21 sucks in debris from the top of the pool, in order to improve the efficiency of cleaning the top of the pool, such as... Figure 3 and Figure 8 As shown, the bottom of the suction shell 21 is fixedly connected to a shovel plate 10 and a base frame 15. The negative pressure hole 22 is located between the shovel plate 10 and the base frame 15. The shovel plate 10 is inclined upward from one side of the base frame 15 to the other side to form a ramp 16. The bottom of the base frame 15 is rotatably connected to multiple moving wheels 14.

[0038] In this embodiment, when the suction shell 21 moves at the bottom of the pool, the suction shell 21 drives the base frame 15 to move and the moving wheels 14 roll relative to the base frame 15, making the movement of the suction shell 21 more stable. The suction shell 21 also drives the shovel plate 10 to move synchronously, so that the shovel plate 10 scoops up the debris at the bottom of the pool, making it easier for the debris at the bottom of the pool to be sucked in by the negative pressure hole 22.

[0039] Specifically, in one embodiment, regarding the aforementioned flexible connector 3:

[0040] like Figures 1-5 As shown, the flexible connector 3 includes a telescopic soft cover 31 fixedly connected between two air intake shells 21. The interior of the telescopic soft cover 31 forms a communicating cavity 33 that communicates with the inner cavity 23, and the bottom of the telescopic soft cover 31 is open to form a communicating hole 32 that communicates with the negative pressure hole 22.

[0041] In this embodiment, when the two suction shells 21 move, the telescopic soft cover 31 is stretched by the two suction shells 21, so that the telescopic soft cover 31 is unfolded and adjusted to the length required by the personnel, thereby connecting the inner cavity 23 with the connecting cavity 33 and connecting the negative pressure hole 22 with the connecting hole 32. When the flexible air supply component draws gas from the inner cavity 23 and the connecting cavity 33, the negative pressure hole 22 and the connecting hole 32 draw in debris from the bottom of the pool under negative pressure.

[0042] Specifically, in one embodiment, regarding the aforementioned flexible gas conveying component:

[0043] like Figures 1-4As shown, the flexible air delivery component includes a connecting hose 1, which is fixedly connected between the tops of the two air intake shells 21, and a material delivery pipe 4 is fixedly connected between the storage component and the connecting hose 1.

[0044] In this embodiment, the negative pressure component operates, thereby drawing out the gas inside the receiving component, creating a negative pressure inside the receiving component. This causes the feed pipe 4 on the receiving component to generate suction, which in turn draws in the gas from the connecting hose 1. This suction causes the two suction components 2 and the flexible connector 3 to generate suction. The two suction components 2 and the flexible connector 3 are moved by the traction rope. As the two suction components 2 and the flexible connector 3 move, they adsorb debris from the bottom of the pool, thereby cleaning the bottom of the pool.

[0045] Specifically, in one embodiment, regarding the aforementioned storage component:

[0046] like Figures 1-4 , Figures 6-7 As shown, the storage component includes an outer shell 5, with a removable top plate 6 mounted on the top of the outer shell 5, and a cavity formed between the outer shell 5 and the top plate 6.

[0047] In this embodiment, when the conveying pipe 4 picks up debris, the debris is conveyed through the conveying pipe 4 to the cavity between the outer shell 5 and the top plate 6. When personnel need to clean the debris in the cavity, they pull the top plate 6 to separate the top plate 6 from the outer shell 5, and then the debris inside the cavity can be taken out for cleaning.

[0048] Furthermore, regarding how the aforementioned outer casing 5 works in this utility model, as follows: Figures 1-4 , Figures 6-7 As shown, the outer casing 5 includes a housing 51, the top of the housing 51 is open to form a mounting cavity 53, a side hole 52 is formed on one side of the housing 51, and a drain pipe 54 is fixedly connected to the other side. The material conveying pipe 4 communicates with the side hole 52, and the horizontal height of the lowest point of the air inlet of the negative pressure component is higher than the horizontal height of the lowest point of the drain pipe 54.

[0049] In this embodiment, the negative pressure component operates, thereby drawing gas from inside the housing 51, creating a negative pressure inside the housing 51. This causes the feed pipe 4 on the housing 51 to generate suction, drawing gas from the connecting hose 1. This suction causes the two suction components 2 and the flexible connector 3 to generate suction. The two suction components 2 and the flexible connector 3 are moved by the traction rope. As the two suction components 2 and the flexible connector 3 move, they adsorb debris from the bottom of the pool, thus cleaning the bottom of the pool. The debris enters the installation cavity 53 along with the water and is then discharged through the drain pipe 54.

[0050] Furthermore, to facilitate the collection of debris inside the mounting cavity 53, such as... Figures 6-7 As shown, a storage frame 12 is fixedly connected to the bottom of the top plate 6, and the storage frame 12 is open on the side facing the side hole 52 to form a storage cavity 13.

[0051] In this embodiment, to prevent debris from being accidentally discharged from the drain pipe 54, the top plate 6 is placed on the housing 51, and the storage frame 12 is installed inside the storage cavity 13. When water and debris enter the installation cavity 53, the debris is collected by the storage frame 12, and the water is discharged through the drain pipe 54 after passing through the storage frame 12.

[0052] Specifically, in one embodiment, regarding how the aforementioned negative pressure component works:

[0053] like Figures 1-2 , Figures 6-7 As shown, the negative pressure component includes a negative pressure pump 9 fixedly connected to the top of the top plate 6. The air inlet end and the air outlet end of the negative pressure pump 9 are respectively fixedly connected to an air inlet pipe 11 and an air outlet pipe 8. One end of the air inlet pipe 11 passes through the top plate 6 and extends into the interior of the storage cavity 13. A handle 7 is fixedly connected to the top of the top plate 6, and the handle 7 is located on one side of the negative pressure pump 9.

[0054] In this embodiment, the negative pressure pump 9 operates, thereby drawing gas from the inside of the storage frame 12 through the air inlet pipe 11 on the negative pressure pump 9 and discharging the gas through the air outlet pipe 8, creating negative pressure inside the mounting cavity 53, which can then be used to clean the bottom of the pool.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
