[0001] The present invention relates to the technical field of swimming pool robots, and in particular to a swimming pool cleaning device. Background Art

[0002] The swimming pool cleaning device has a built-in power system. During the operation of the swimming pool cleaning device, the stored electrical energy is used to power multiple actuators such as the water pump, moving mechanism and roller brush, so that the swimming pool cleaning device can move on the bottom and wall of the swimming pool, and at the same time enable the roller brush to roll and form an internal and external circulation of water to clean the pollutants on the bottom and wall of the swimming pool, as well as other functions.

[0003] This shows that the power system is the key to ensuring the normal operation of the pool cleaning device underwater, and its energy storage capacity directly affects the product's underwater endurance. Therefore, how to further improve the endurance under the given performance of the power system is a very important issue.

[0004] Summary of the Invention

[0005] In order to solve the defect of poor endurance of existing swimming pool cleaning devices, the present invention provides a swimming pool cleaning device.

[0006] The technical solution adopted by the present invention is a swimming pool cleaning device, comprising a shell, a drainage module and a filter module disposed inside the shell, the shell being provided with a water inlet and a first water outlet, the water inlet, the filter module, the drainage module and the first water outlet being connected in sequence to form a water flow channel; a dividing assembly is further disposed inside the shell, the dividing assembly constraining the inner cavity of the shell to form a water inlet chamber and at least one accommodating chamber, the water inlet chamber being isolated from the accommodating chamber.

[0007] In one embodiment, the drainage module, the housing and the partition assembly together form the water inlet chamber.

[0008] In one embodiment, the water inlet chamber is formed inside the dividing assembly, and at least one side of the water inlet chamber is connected to the water flow channel.

[0009] In one embodiment, the maximum distance between the wall of the filtration module and the wall of the partition assembly or the drainage module facing it is less than 35 mm.

[0010] In one embodiment, it further includes a driving module and an energy supply module, wherein the driving module and the energy supply module are both arranged in the accommodating chamber, and the filtering module is arranged in the water inlet chamber.

[0011] In one embodiment, a second water outlet is further provided on the housing, and the second water outlet is communicated with the water flow channel.

[0012] In one embodiment, a fifth opening is further provided on the first surface of the dividing assembly, the fifth opening is communicated with the second water outlet and forms a first channel, and an opening and closing mechanism is provided on the first channel.

[0013] In one embodiment, the fifth opening is provided at an end of the partition assembly away from the drainage module.

[0014] The present invention also discloses a swimming pool cleaning device, including a filter module and a drainage module, and also includes a water inlet chamber. The filter module, water inlet chamber and drainage module are connected in sequence, and fluid flows in the water inlet chamber under the action of the drainage module.

[0015] In one embodiment, the maximum distance between the wall of the filtration module and the wall of the water inlet chamber or the drainage module facing it is less than 35 mm.

[0018] The present invention also discloses a swimming pool cleaning device, comprising an outer shell, a drainage module and a filter module disposed inside the outer shell, wherein the outer shell is provided with a water inlet and a first water outlet, and the water inlet, the filter module, the drainage module and the first water outlet are sequentially connected to form a water flow channel; a water inlet chamber is also formed inside the outer shell, the filter module is accommodated in the water inlet chamber, and the side wall of the water inlet chamber divides the outer shell into a first cavity and a second cavity, and the water inlet chamber and the water flow channel are both located in the first cavity and are connected.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the pool cleaning device of the present invention, a partitioning assembly confines the inner cavity of the housing to form an inlet chamber and a receiving chamber. When liquid filtered by the filter module does not flow into the receiving chamber, the filtered pool water is confined only to the inlet chamber. The inlet chamber is formed within the housing and has a smaller volume than the housing. This reduces the space available for pool water to escape within the inlet chamber, making it easier to form orderly streamlines than within the housing. This reduces turbulence and fluid resistance, and the drain module consumes less energy when extracting pool water from the inlet chamber, thereby improving efficiency. Ultimately, given a given power system performance, the endurance of the pool cleaning device can be significantly improved. When liquid filtered by the filter module flows into the inlet chamber and the receiving chamber, the inlet and receiving chambers divide the inner cavity of the pool cleaning device housing into two smaller spaces. Liquid cannot escape between the inlet and receiving chambers, thus reducing turbulence and energy consumption by the drain module when extracting pool water from the inlet chamber.

[0035] To make the objectives, technical solutions, and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0036] In one embodiment, as shown in Figures 1-2 and 4, a swimming pool cleaning device includes a housing 10, a drainage module 30, and a filtration module 40. The drainage module 30 and the filtration module 40 are both disposed within the housing 10. The housing 10 is provided with a water inlet 11 and a first water outlet. The water inlet 11, the filtration module 40, the drainage module 30, and the first water outlet are sequentially connected to form a water flow channel. A partitioning assembly 20 is also disposed within the housing 10. The partitioning assembly 20 constrains the inner cavity of the housing 10 to form a water inlet chamber 24 and a receiving chamber. The water inlet chamber 24 is isolated from the receiving chamber. The filtration module 40, the water inlet chamber 24, and the drainage module 30 are sequentially connected. Fluid flows within the water inlet chamber 24 under the action of the drainage module 30.

[0037] During use, pool water to be cleaned flows into the housing 10 through the water inlet 11, is filtered by the filter module 40, and flows into the water inlet chamber 24. The pool water in the water inlet chamber 24 is then pumped out by the drainage module 30 and ultimately flows out of the pool cleaning device through the first water outlet. In this embodiment, the first water outlet is the mounting hole that connects the drainage module 30 to the outside.

[0038] In conventional pool cleaning devices, pool water filtered by filter module 40 tends to escape throughout housing 10. Drain module 30, acting as the primary power source for the pool water's circulation, extracts the scattered water from housing 10. In contrast, in the pool cleaning device of this embodiment, when the liquid filtered by filter module 40 does not flow into the accommodating chamber, the pool water is confined solely to inlet chamber 24. Inlet chamber 24 is formed within housing 10 and has a smaller volume than that of housing 10. This reduces the space available for pool water to escape within inlet chamber 24, making it easier to form orderly streamlines compared to within housing 10. This reduces water flow turbulence and fluid resistance, and the drain module 30 consumes relatively less energy when extracting the pool water from inlet chamber 24, thereby improving efficiency. Ultimately, given a given power system's performance, the device's endurance is significantly improved. When the liquid filtered by the filtration module 40 flows into the water inlet chamber 24 and the accommodating chamber respectively, the water inlet chamber 24 and the accommodating chamber divide the inner cavity of the swimming pool cleaning device housing into two smaller spaces. The liquid cannot escape between the water inlet chamber 24 and the accommodating chamber, which also reduces the turbulence of the water flow. The energy consumption of the drainage module 30 when extracting the pool water in the water inlet chamber 24 is also reduced.

[0039] Specifically, the drainage module 30 includes a pump motor, an impeller, a flow deflector, and a pressure hood. The pump motor provides the driving force, which rotates the impeller. The impeller uses dynamic principles to push water from a low-pressure area to a high-pressure area. The impeller's rotation accelerates and directs the water flow. The flow deflector is installed around the impeller to guide the flow. The pressure hood increases the outlet pressure, allowing the liquid to overcome resistance and gravity and be pumped out smoothly.

[0040] In one embodiment, as shown in Figures 5-7, the filter module 40 is disposed in the water inlet chamber 24, so that water filtered by the filter module 40 can directly flow into the water inlet chamber 24, and directly installing the filter module 40 in the water inlet chamber 24 can also save space.

[0041] Specifically, the first surface of the partition assembly 20 defines a first opening 21 through which the filter module 40 communicates with the water inlet 11 . The second surface of the partition assembly 20 defines a second opening 22 through which the water inlet chamber 24 communicates with the drainage module 30 .

[0042] The filter module 40 includes a filter cartridge 41. The wall of the filter cartridge 41 is formed with at least a third opening 42 and a fourth opening 43. The third opening 42 communicates with the first opening 21 and the water inlet 11, while the fourth opening 43 is provided with a filtering structure. This allows water within the filter cartridge 41 to be filtered through the fourth opening before flowing out toward the drainage module 30. Fluid enters the pool cleaning device through the water inlet 11 of the housing 10. The fluid flowing into the water inlet 11 passes through the first opening 21 of the partition assembly 20 and the third opening 42 of the filter cartridge 41, then into the filter cartridge 41. After being filtered by the filtering structure of the filter cartridge 41, the fluid exits the filter cartridge 41, reaches between the partition assembly 20 and the filter cartridge 41, and is then drawn out through the drainage module 30.

[0043] In this embodiment, liquid filtered by the filtration module 40 enters the water inlet chamber 24. Driven by the drainage module 30, the liquid within the water inlet chamber 24 flows out of the pool cleaning device. By dividing the space within the pool cleaning device into the water inlet chamber 24 and the storage chamber, compared to the prior art design in which the drainage module 30 drives the liquid from the entire pool cleaning device out of the cleaning device, the space for liquid to escape is limited, and the liquid moves primarily within the water inlet chamber. This reduces water flow resistance, conserves the energy required by the drainage module 30 to drain water, and improves the endurance of the pool cleaning device.

[0044] The accommodating chamber accommodates the energy supply module 50 and the driver module 60, protecting them and reducing the likelihood of liquid entering the modules and damaging electronic components such as the battery and motor, thereby ensuring the proper functioning of the pool cleaning device. This also addresses the issue of dirt in the pool water entering the energy supply module 50 and the driver module 60, making them difficult to clean.

[0045] In one embodiment, the water inlet chamber can be directly enclosed by a partitioning assembly, and the filter module, the water inlet chamber and the drainage module can be connected in sequence by openings on the partitioning assembly that encloses the water inlet chamber.

[0046] In one embodiment, the partition assembly may include one or more partition plates, which are disposed in the housing of the pool cleaning device, and the cavity in the housing is divided into a water inlet chamber and a receiving chamber by the partition plates.

[0047] In one embodiment, at least one side wall of the filter box is a closed plate structure. When the filter box is installed in place, its side wall plate is connected to the inner wall of the shell, thereby dividing the internal space of the shell into two different chambers, one of which is the aforementioned water inlet chamber.

[0048] In other embodiments, the number of accommodating chambers may be multiple, each accommodating an energy supply module, a driving module, etc.

[0049] In one embodiment, the pool cleaning device further includes a drive module 60, a power supply module 50, a housing 10, and a partition assembly 20 disposed within the housing 10. The partition assembly 20 and the housing 10 collectively define a water inlet chamber 24 and a receiving chamber. The drainage module 30 is in communication with the partition assembly 20, and the drainage module 30 and the partition assembly 20 collectively enclose the water inlet chamber 24. Specifically, the water inlet chamber 24 includes four side surfaces, a top surface, and a bottom surface. The housing 10 and the partition assembly 20 respectively define the three side surfaces, the top surface, and the bottom surface of the water inlet chamber 24. The fourth side surface of the water inlet chamber 24 is defined by the drainage module 30.

[0050] Both the drive module 60 and the power supply module 50 are housed within the chamber, reducing the likelihood of liquid entering the power supply module 50 and drive module 60 and damaging electronic components such as the battery and motor. The filter module 40 is housed within the water inlet chamber 24, reducing fluid resistance and requiring relatively little energy for the drain module 30 to pump the pool water from the water inlet chamber 24. The maximum distance between the wall of the filter module 40 and the opposing wall of the partition assembly 20 or the drain module 30 is less than 35 mm. This reduces the capacity of the water inlet chamber 24 defined by the partition assembly 20, shortens the distance the drain module 30 must pump the pool water, and reduces energy consumption, resulting in a more sustainable pool cleaning device.

[0051] In this embodiment, the top surface of the water inlet chamber 24 is the shell, and the bottom surface and three side surfaces are all dividing components. At the same time, the dividing components need to be connected and interfered with the walls of the shell, so that the internal space of the shell is divided into two different chambers, the water inlet chamber 24 and the accommodating chamber, through the dividing components.

[0052] In other embodiments, other structures may be used to define a water inlet chamber and a receiving chamber in the swimming pool cleaning device to reduce energy consumption.

[0053] In one embodiment, a swimming pool cleaning device includes a housing 10, a drainage module 30, and a filtration module 40, with the drainage module 30 and filtration module 40 disposed within the housing 10. The housing 10 is provided with a water inlet 11 and a first water outlet. The water inlet 11, filtration module 40, drainage module 30, and first water outlet are sequentially connected to form a water flow channel. A water inlet chamber 24 is also formed within the housing 10, with the filtration module 40 housed within the water inlet chamber 24. The sidewalls of the water inlet chamber 24 divide the housing 10 into a first cavity and a second cavity. The water inlet chamber 24 and the water flow channel are both located within and interconnected within the first cavity. The drive module 60 and power supply module 50 are disposed within the second cavity to reduce energy consumption and prevent damage to electronic components.

[0054] In this embodiment, the water inlet chamber 24 is surrounded by an outer shell and a side wall plate, and the side wall plate divides the inner space of the outer shell into a first cavity and a second cavity. The overall structure is simple and convenient.

[0055] In one embodiment, the maximum spacing between the wall of the filter module 40 and the wall of the partition assembly 20 it faces is less than 35 mm. Specifically, the gap between the filter module 40 and the inner wall of the partition assembly 20 is less than 35 mm. This limits the range of pool water that escapes the filter module 40 and reduces energy consumption by the drain module 30. Furthermore, the maximum spacing between the wall of the filter module 40 and the inner wall of the partition assembly 20 it faces is less than 35 mm. This limits the distance between the filter module 40 and the drain module 30 it faces, shortening the distance the drain module 30 must pump water, further reducing energy consumption. Given a given power system performance, this significantly improves the endurance of the pool cleaning device. Furthermore, the spacing between the wall of the filter module 40 and the inner wall of the partition assembly 20 and / or the drain module 30 is less than 30 mm. While maintaining the capacity of the filter module 40, the capacity of the water inlet chamber 24 defined by the partition assembly 20 is further reduced, further shortening the distance the drain module 30 must pump water, reducing energy consumption by the drain module 30, and improving the endurance of the pool cleaning device.

[0056] In other embodiments, the filter module 40 may further include multiple filter boxes 41 to improve the filtration efficiency of the pool cleaning device. A handle is provided on the top of the filter box 41 to facilitate manual lifting and movement of the filter box 41.

[0057] In one embodiment, an annular platform is provided within the water inlet chamber 24, and a protrusion that matches the annular platform is provided on the circumference of the filter cartridge 41. When the filter cartridge 41 is inserted into the annular platform, the protrusion abuts the annular platform, and the filter cartridge 41 is installed within the water inlet chamber 24 through the cooperation between the annular platform and the protrusion. In other embodiments, a receiving cavity that matches the shape of the filter cartridge 41 can be provided within the partition assembly 20, so that the filter cartridge 41 can be directly placed within the receiving cavity.

[0058] In one embodiment, as shown in Figures 3-4, the pool cleaning device further includes a drive module 60 and a power supply module 50. The drive module 60 primarily includes electronic components such as a motor and is used to drive the cleaning device and the roller brush. The power supply module 50 primarily includes components such as a battery and provides energy to the various modules within the cleaning device. The drive module 60 and power supply module 50 are disposed within a chamber. Liquid entering the pool cleaning device is primarily discharged through the filter module, the water inlet chamber, and the water outlet module, with minimal liquid entering the chamber. This reduces the possibility of water ingress into the power supply module 50 and drive module, potentially damaging the battery, motor, and other electronic components. This also addresses the issue of dirt in the pool water entering the power supply module 50 and drive module, making it difficult to clean.

[0059] In one embodiment, a fifth opening 23 is further defined on the first surface of the partition assembly 20, and a second water outlet 12 is further defined on the housing 10. The second water outlet 12 communicates with the fifth opening 23 to form a first channel. Consequently, after the pool cleaning device is removed from the pool, water in the water inlet chamber 24 can quickly flow out through the first channel, increasing the drainage speed of the pool cleaning device and facilitating subsequent maintenance.

[0060] In one embodiment, an opening and closing mechanism is provided on the second water outlet 12, movable between a first position and a second position. When the opening and closing mechanism is in the first position, the first channel allows water to flow through; when the opening and closing mechanism is in the second position, the first channel blocks water flow, forming a water channel. Thus, when the pool cleaning device is still within the pool, the opening and closing mechanism remains in the second position, preventing the water inlet chamber 24 from exchanging fluid with the pool through the first channel, which could disrupt the water circulation of the pool cleaning device and waste work. When the pool cleaning device is removed from the pool, the opening and closing mechanism moves from the second position to the first position, opening the first channel to quickly drain the water within the pool cleaning device. Specifically, the opening and closing mechanism can be a pivoting baffle, gland, door panel, sliding door, or lift gate that seals with the second water outlet 12. It can be opened passively by gravity or actively by a drive mechanism. In other embodiments, the opening and closing mechanism can be located at any position on the fifth opening 23 or the first channel, similarly serving to close and open the first channel.

[0061] In one embodiment, a third water outlet 25 is further included. The third water outlet 25 is located at the lowest point of the center of gravity after the pool cleaning device 324 is lifted. In one embodiment, the third water outlet 25 is located above the rear roller brush. The third water outlet 325 increases the water discharge speed. When the pool cleaning device is lifted, the remaining water in the pool cleaning device will be quickly discharged through the second water outlet 12 and the second water outlet 12.

[0062] The first water outlet 12 and the second water outlet 12 are both provided with an opening and closing mechanism to prevent sewage from flowing into the interior of the swimming pool cleaning device when the swimming pool cleaning device is working.

[0063] In one embodiment, the opening and closing mechanism moves between a first position and a second position based on the pool cleaning device's depth information. For example, a water-discharge detection assembly can detect the pool cleaning device's depth information to determine whether the device has exited the pool water, thereby adjusting the opening and closing mechanism's position from the second position to the first position. Furthermore, upon detecting that the device is exiting the pool water, the water-discharge detection assembly can control the device to shut down its pump motor if the user does not manually shut down the device, thereby preventing idling due to grounding and reducing energy waste. The water-discharge detection assembly can include at least one of a Hall effect sensor, a water level sensor, or a power sensor.

[0064] In one embodiment, the water discharge detection component includes a power sensor. When the pool cleaning device is outside the pool water, the power of its pump motor will decrease. The power sensor can detect the power of the pump motor to determine whether the pool cleaning device is discharging water.

[0065] In one embodiment, as shown in FIG3 , the water outflow detection device includes an electrode-type water immersion sensor. The electrode-type water immersion sensor comprises two electrode sheets 51 disposed near the rear end and bottom of the pool cleaning device. When either electrode sheet 51 leaves the water, the passage formed by the two electrode sheets 51 is disconnected, indicating that the pool cleaning device has discharged water. This in turn controls the opening and closing mechanism to move to the first position, thereby opening the first passage and achieving rapid drainage. In other embodiments, the water outflow detection device may also include a thermal-sensitive water immersion sensor, an optical water immersion sensor, or the like.

[0066] In one embodiment, the water outlet detection device may further include a Hall sensor or other sensor that can represent the depth information of the swimming pool cleaning device.

[0067] In one embodiment, the fifth opening 23 is disposed at an end of the partition assembly 20 away from the drainage module 30. The drainage module 30 can drain water in the vicinity thereof, so that the remaining water is primarily concentrated at the end of the partition assembly 20 away from the drainage module 30. Consequently, the fifth opening 23 is disposed at the end of the partition assembly 20 away from the drainage module 30. Furthermore, the fifth opening 23 is disposed at the bottom of the partition assembly 20 to facilitate rapid drainage of remaining water by gravity, thereby facilitating subsequent cleaning and maintenance of the pool cleaning device.
