[0031] See appendix Figure 1 This embodiment provides a water tank cleaning device, including: a main body, including an inlet 1 and an outlet; the inlet 1 is located at the bottom of the main body; water can be guided to enter from the inlet 1 and flow out through the outlet; a cleaning component, disposed on the main body, including a first cleaning component 2 and a second cleaning component 3, the second cleaning component 3 being at least partially in contact with the surface of the water tank; and a driving component, driven by the cleaning component, the cleaning component cleans the surface of the water tank under the drive of the driving component.
[0032] In this embodiment, the pool cleaning device can clean the bottom of the pool, the side walls of the pool, and the liquid surface inside the pool. The main body is provided with an inlet 1 and an outlet. The inlet 1 and the outlet work together to clean the bottom of the pool, the side walls of the pool, and the liquid surface inside the pool, thereby improving the adaptability of the pool cleaning device. The liquid entering through the inlet 1 can flow out through the outlet.
[0033] In this embodiment, by cooperating with the first cleaning component 2 and the second cleaning component 3, the first cleaning component 2 can perform initial cleaning of the pool surface during rotation, and the second cleaning component 3 can perform secondary cleaning of the pool surface during rotation. This enables the pool cleaning equipment to clean the pool surface more effectively, improves the cleaning effect and efficiency of the pool cleaning equipment, and enhances the market competitiveness of the pool cleaning equipment.
[0034] In this embodiment, the structure of the drive component is not limited, as long as the drive component can drive the first cleaning component 2 and the second cleaning component 3 to rotate respectively.
[0035] In this embodiment, the driving component is a drive motor.
[0036] In some possible embodiments, the first cleaning component 2 and the second cleaning component 3 are respectively arranged on both sides or on the same side of the water inlet 1. By arranging the first cleaning component 2 and the second cleaning component 3 on both sides or on the same side of the water inlet 1, the first cleaning component 2 and the second cleaning component 3 can clean the surface of the pool respectively, thereby improving the cleaning effect and cleaning efficiency.
[0037] In some possible embodiments, the second cleaning component 3 has a smaller cleaning working surface than the first cleaning component 2. By setting the cleaning working surface of the second cleaning component 3 to be smaller than that of the first cleaning component 2, the second cleaning component 3 can clean dirt that the first cleaning component 2 cannot clean, such as dirt in the crevices of the pool bottom. When the first cleaning component 2 and the second cleaning component 3 work together, the cleaning effect and cleaning efficiency of the pool cleaning equipment can be improved.
[0038] In this embodiment, the size of the cleaning surface of the second cleaning component 3 is not limited, as long as it is smaller than the cleaning surface of the first cleaning component 2 and can be used for dirt in the crevices of the pool.
[0039] In some possible embodiments, the first cleaning component 2 is closer to the head or tail of the cleaning device than the second cleaning component 3. This arrangement allows the first cleaning component 2 to clean first when it encounters dirt. Since the cleaning working surface of the second cleaning component 3 is smaller than that of the first cleaning component 2, after the first cleaning component 2 has finished cleaning, the second cleaning component 3 can clean the areas that the first cleaning component 2 cannot clean, thereby ensuring the cleaning efficiency and cleaning effect of the pool cleaning device.
[0040] In this embodiment, the first cleaning component 2 and the second cleaning component 3 are arranged at intervals along the forward direction of the pool cleaning equipment;
[0041] With the first cleaning component 2 and the second cleaning component 3 respectively located on both sides of the water inlet 1, and the first cleaning component 2 being closer to the head or tail of the cleaning device than the second cleaning component 3, the first cleaning component 2 first cleans the area to be cleaned, and the dirt removed by the first cleaning component 2 enters the water inlet 1. When the water tank cleaning device moves forward or backward, the second cleaning component 3 cleans the area to be cleaned again, and the dirt removed by the second cleaning component 3 enters the water inlet 1.
[0042] When the first cleaning component 2 and the second cleaning component 3 are respectively located on the same side of the water inlet 1, and the first cleaning component 2 is closer to the head or tail of the cleaning device than the second cleaning component 3, the first cleaning component 2 first cleans the area to be cleaned. The dirt that is cleaned moves toward the second cleaning component 3 under the action of the first cleaning component 2. The second cleaning component 3 then cleans the area to be cleaned again. The second cleaning component 3 carries the dirt it cleaned and the dirt cleaned by the first cleaning component 2 into the water inlet 1.
[0043] In this embodiment, the first cleaning component 2 and the second cleaning component 3 are arranged on both sides of the water inlet 1. Compared with the components arranged on the same side of the water inlet 1, the cleaning components 2 and 3 can promptly carry the dirt into the water inlet 1, preventing the dirt from spreading into the pool, thereby ensuring the cleaning efficiency and cleaning effect of the pool cleaning equipment.
[0044] In some possible embodiments, the first cleaning component 2 is further away from the water inlet 1 than the second cleaning component 3. By setting the first cleaning component 2 closer to the head or tail of the pool cleaning device than the second cleaning component 3, the first cleaning component 2 is further away from the water inlet 1 than the second cleaning component 3. Compared with the first cleaning component 2, the second cleaning component 3 is able to clean dirt in narrow spaces, and the dirt cleaned by the second cleaning component 3 can quickly flow to the water inlet 1, thereby improving cleaning efficiency.
[0045] In this embodiment, the distance between the second cleaning component 3 and the water inlet 1 is 10%-15% of the length of the pool cleaning equipment. This setting can prevent the dirt from not being guided to the water inlet 1 due to the excessive distance between the two, thereby ensuring that the dirt cleaned by the second cleaning component 3 can enter the water inlet 1 and ensure the cleaning effect.
[0046] In this embodiment, the distance between the second cleaning component 3 and the water inlet 1 is 10%-12%, 10%-15%, 12%-15%, 13%-15%, or 14%-15% of the length of the pool cleaning equipment.
[0047] In this embodiment, the length of the first cleaning component 2 is greater than the length of the water inlet 1 along the axial direction of the first cleaning component 2; and the length of the second cleaning component 3 is greater than the length of the water inlet 1 along the axial direction of the second cleaning component 3. This setting ensures that the size of the water inlet 1 is reasonably set, and can avoid unnecessary waste caused by the water inlet 1 being too large.
[0048] In this embodiment, the first cleaning component 2 and the second cleaning component 3 are located on the same side of the water inlet 1, with the second cleaning component 3 closer to the water inlet 1 than the first cleaning component 2. If the first cleaning component 2 is closer to the water inlet 1 than the second cleaning component 3, and the first cleaning component 2 and the second cleaning component 3 are located on opposite sides of the water inlet 1, the second cleaning component 3 will clean the area to be cleaned first. Due to its smaller cleaning surface, the cleaning force is insufficient, and it cannot clean thoroughly, meaning that it may not reach the dirt in the crevices. This will result in dirt remaining in the crevices even after the area to be cleaned has been cleaned by the first cleaning component 2. Consequently, the dirt in the narrow areas cleaned by the second cleaning component 3 cannot all flow to the water inlet 1, and some dirt flows back to the narrow areas, which will reduce the cleaning effect of the pool cleaning equipment.
[0049] In this embodiment, the first cleaning component 2 and the second cleaning component 3 are disposed on both sides of the water inlet 1, and the second cleaning component 3 is closer to the water inlet 1 than the first cleaning component 2. Since the cleaning working surface of the first cleaning component 2 is larger than that of the second cleaning component 3, the first cleaning component 2 can clean larger dirt. By placing the first cleaning component 2 further away from the water inlet 1 than the second cleaning component 3, this arrangement can ensure that the dirt cleaned by the first cleaning component 2 has sufficient guiding distance, avoiding the situation where the guiding distance is too short, causing the dirt to remain wrapped around the first cleaning component 2 and unable to enter the water inlet 1. The dirt cleaned by the second cleaning component 3 is smaller in size and does not get wrapped around the second cleaning component 3. By placing the second cleaning component 3 closer to the water inlet 1, the dirt can be quickly guided into the water inlet 1.
[0050] In some possible embodiments, under the drive of the drive component, the second cleaning component 3 rotates in the same or opposite directions as the first cleaning component 2. By controlling the rotation directions of the second cleaning component 3 and the first cleaning component 2 to be opposite, both the first cleaning component 2 and the second cleaning component 3, which are located on both sides of the water inlet 1, can guide dirt towards the water inlet 1. However, if the rotation directions of the second cleaning component 3 and the first cleaning component 2 are opposite, the second cleaning component 3 will provide a backward force when it encounters an obstacle, causing the pool cleaning device to jam and be unable to move forward. By controlling the rotation directions of the second cleaning component 3 and the first cleaning component 2 to be the same, the backward force provided by the second cleaning component 3 can be avoided from causing the pool cleaning device to jam. When the rotation directions of the second cleaning component 3 and the first cleaning component 2 are set to be the same, dirt can still be cleaned, but it cannot be guided to the water inlet 1. The dirt can only be sucked in when the pool cleaning device passes by again. It can be seen that the cleaning efficiency of the second cleaning component 3 and the first cleaning component 2 rotating in the same direction is lower than the cleaning efficiency of the second cleaning component 3 and the first cleaning component 2 rotating in opposite directions.
[0051] In some possible embodiments, when the second cleaning component 3 rotates in the opposite direction to the first cleaning component 2, the second cleaning component 3 can guide at least a portion of the water flow toward the inlet 1 during rotation. This arrangement can improve the cleaning efficiency and cleaning effect of the pool cleaning equipment.
[0052] In some possible embodiments, when the first cleaning component 2 and the second cleaning component 3 are located on the same side of the water inlet 1, the driving component can drive the first cleaning component 2 and the second cleaning component 3 to rotate in the same direction; when the first cleaning component 2 and the second cleaning component 3 are located on opposite sides of the water inlet 1, the driving component can drive the first cleaning component 2 and the second cleaning component 3 to rotate in opposite directions. The first cleaning component 2 and the second cleaning component 3 being located on the same side and rotating in the same direction can ensure that the first cleaning component 2 and the second cleaning component 3 can clean the position to be cleaned synchronously. The first cleaning component 2 and the second cleaning component 3 being located on opposite sides and rotating in opposite directions also ensures that the dirt cleaned by the first cleaning component 2 flows towards the water inlet 1, and the dirt cleaned by the second cleaning component 3 can also flow towards the water inlet 1, thus ensuring cleaning efficiency and cleaning effect.
[0053] In this embodiment, when the first cleaning component 2 is located at the head of the pool cleaning device, that is, when the first cleaning component 2 is close to the forward end face of the pool cleaning device, and the first cleaning component 2 and the second cleaning component 3 are arranged on both sides of the water inlet 1, the first cleaning component 2 rotates in the forward direction, and the second cleaning component 3 can rotate in the forward direction or in the reverse direction. The forward rotation and the reverse rotation are opposite in direction. The forward rotation is when viewed from the end face of the first cleaning component 2, the first cleaning component 2 rotates counterclockwise.
[0054] In the initial state, the second cleaning component 3 rotates in the opposite direction. If the second cleaning component 3 encounters an obstacle, the control drive component drives the second cleaning component 3 to rotate in the forward direction to avoid the second cleaning component 3 providing backward force.
[0055] In some other possible embodiments, when the first cleaning component 2 is located at the head of the pool cleaning device and the first cleaning component 2 and the second cleaning component 3 are located on the same side of the inlet 1, the first cleaning component 2 is closer to the head of the pool cleaning device than the inlet 1, and both the first cleaning component 2 and the second cleaning component 3 rotate in the forward direction.
[0056] In the initial state, the first cleaning component 2 rotates in the forward direction and the second cleaning component 3 rotates in the reverse direction. If the second cleaning component 3 encounters an obstacle, the control drive component drives the second cleaning component 3 to rotate in the forward direction to avoid the second cleaning component 3 providing backward force.
[0057] In some possible embodiments, the pool cleaning device also includes a baffle assembly. The baffle assembly, the first cleaning component 2, and the second cleaning component 3 cooperate to guide the water flow into the inlet 1. By setting the baffle assembly, the guiding ability of the water flow can be improved, and the baffle assembly can ensure that the dirt is located in the area enclosed by the baffle assembly, the first cleaning component 2, and the second cleaning component 3, thereby ensuring that most of the dirt cleaned by the cleaning components can enter the inlet 1.
[0058] In some possible embodiments, the baffle assembly is detachably disposed at the bottom of the main body, and the baffle assembly, the first cleaning assembly 2 and the second cleaning assembly 3 cooperate to form a water flow guiding area around the inlet 1.
[0059] In some possible embodiments, the baffle assembly includes a first baffle 4 and a second baffle 5 disposed opposite to each other; the first baffle 4 and the second baffle 5 are respectively disposed on both sides of the water inlet 1; along the circumference of the water inlet 1, the first baffle 4, the first cleaning component 2, the second baffle 5 and the second cleaning component 3 are disposed sequentially to form a water flow guiding area.
[0060] In this embodiment, the length and height of the first baffle 4 and the second baffle 5 are not limited, and are set according to the overall size of the water tank cleaning equipment, as long as the first baffle 4, the first cleaning component 2, the second baffle 5 and the second cleaning component 3 can form a water flow guiding area.
[0061] In some possible embodiments, the first cleaning component 2 includes a roller brush, and the second cleaning component 3 includes a bristle brush. The material of the first cleaning component 2 is different from that of the second cleaning component 3, and the sizes of the first cleaning component 2 and the second cleaning component 3 are different. Since the bristles of the bristle brush are small, they can clean the dirt in the crevices of the pool bottom that the roller brush cannot clean. Furthermore, by arranging the bristle brush and the roller brush sequentially along the forward direction of the pool cleaning equipment, it is possible to achieve a second cleaning of the pool bottom after the roller brush performs the initial cleaning of the area to be cleaned, thereby cleaning the dirt in the crevices of the pool bottom and further improving the cleaning effect and efficiency of the pool cleaning equipment.
[0062] In this embodiment, the roller brush in the first cleaning component 2 is made of rubber and has a flat and wide bristle structure. This design makes it difficult for the first cleaning component 2 to clean dirt in the crevices. The second cleaning component 3 is a bristle brush with smaller bristles, which can clean dirt in the crevices.
[0063] In this embodiment, the second cleaning component 3 includes: a rotating part; at least one set of bristles, wherein the at least one set of bristles is arranged at intervals along the circumference of the rotating part, and each set of bristles is distributed along the rotation axis of the rotating part.
[0064] In some possible embodiments, at least a portion of the second cleaning component 3 is located at the bottom of the cleaning device. This arrangement ensures that the second cleaning component 3 can clean the surface of the pool and guarantee the cleaning effect of the second cleaning component 3.
[0065] In this embodiment, at least a portion of the first cleaning component 2 is also located at the bottom of the pool cleaning device. This arrangement ensures that the first cleaning component 2 can clean the surface of the pool and guarantee the cleaning effect of the first cleaning component 2.
[0066] In some possible embodiments, the pool cleaning equipment also includes a detection device for detecting whether the cleaning equipment is trapped by an obstacle below it. If trapped, the drive component can stop driving the second cleaning component 3 to rotate or change the rotation direction of the second cleaning component 3, thereby facilitating the cleaning equipment to get out of the predicament. By setting the detection device, it is possible to quickly detect whether the pool cleaning equipment is trapped, thereby improving the response speed and sensitivity of the pool cleaning equipment. At the same time, it can realize the fully automated control of the pool cleaning equipment and improve the user experience.
