Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pool cleaning, and in particular to a pool machine. BACKGROUND

[0002] The pool machine is a device capable of automatically cleaning the pool. The existing pool machine comprises a machine body and a roller brush, the roller brush is rotatably arranged in the machine body, and the machine body has a filter assembly. When the roller brush rotates, it can scrub the pool bottom and pool wall, so that the impurities on the pool bottom and pool wall are entrained in the water flow and sucked into the filter assembly by the pool machine, achieving the purpose of cleaning the pool bottom and pool wall. However, the cleaning effect of the existing pool machine on the pool wall is limited, and it is difficult to achieve the expected effect. CONTENT OF THE UTILITY MODEL

[0003] The embodiment of the present application provides a pool machine, which can improve the cleaning effect on the pool wall.

[0004] In a first aspect, the embodiment of the present application provides a pool machine, which comprises:

[0005] The pool machine body has a front part and a rear part arranged oppositely in the first direction, and the pool machine is configured to clean the pool wall along the first direction; the outer side of the pool machine body has a containing groove;

[0006] The cleaning part is used for cleaning the pool wall, and comprises a mounting part and a cleaning part. The mounting part is arranged in the containing groove and is rotatably connected with the pool machine body; the cleaning part is arranged around the circumferential side of the mounting part, and part of the cleaning part protrudes outward from the containing groove and the pool machine body along the second direction;

[0007] The second direction is perpendicular to the first direction.

[0008] The pool machine of the embodiment of the present application is arranged in such a way that part of the cleaning part protrudes outward from the containing groove and the pool machine body along the second direction, so that when the pool machine approaches the pool wall parallel to the first direction along the second direction, the cleaning part will contact the pool wall before the pool machine body. When the cleaning part contacts the waterline position of the pool wall, the junction between the pool wall and the pool bottom, and other parts to be cleaned on the pool wall, and the cleaning part rotates relative to the pool wall under the driving of the mounting part, the cleaning part will generate friction with the parts to be cleaned, clean the impurities on the parts to be cleaned, so that the impurities enter the pool machine body, and improve the cleaning effect of the pool machine on the pool wall.

[0009] In a second aspect, the embodiment of the present application provides a pool machine, which comprises:

[0010] The pool machine body has a front part and a rear part arranged oppositely in the first direction, and the pool machine is configured to clean the pool wall along the first direction; the outer side of the pool machine body has a containing groove;

[0011] The cleaning piece comprises a mounting portion and a cleaning portion. The mounting portion is arranged in the accommodating groove and rotationally connected with the pool cleaner body. The cleaning portion is arranged around the peripheral side of the mounting portion and partially protrudes out of the accommodating groove. When the pool cleaner approaches the pool wall parallel to the first direction along the second direction, the cleaning portion is configured to contact the pool wall before the pool cleaner body.

[0012] The second direction is perpendicular to the first direction.

[0013] The pool cleaner of the embodiments of the present application is configured such that when the pool cleaner approaches the pool wall parallel to the first direction along the second direction, the cleaning portion contacts the pool wall before the pool cleaner body. Therefore, when the pool cleaner travels along the pool wall parallel to the first direction, the cleaning portion will contact the pool wall before the pool cleaner body and rub against the pool wall. When the cleaning portion contacts the part to be cleaned on the pool wall, such as the waterline position of the pool wall or the junction between the pool wall and the pool bottom, and the cleaning portion rotates relative to the pool wall under the driving of the mounting portion, the cleaning portion will rub against the part to be cleaned to clean the impurities on the part to be cleaned so that the impurities enter the pool cleaner body, thereby enhancing the cleaning effect of the pool cleaner on the pool wall.

[0014] In some embodiments, the pool cleaner body comprises:

[0015] The accommodating groove is located at a position corresponding to the front portion of the body.

[0016] The guide wheel assembly comprises a first guide wheel. The first guide wheel is rotationally arranged at a position corresponding to the rear portion of the body along the second direction, and at least part of the first guide wheel protrudes out of the body. The first guide wheel and the cleaning piece are arranged on the same side of the body.

[0017] Part of the cleaning portion protrudes out of the first guide wheel along the second direction.

[0018] In this way, when the pool cleaner contacts the pool wall parallel to the first direction along the second direction, part of the cleaning portion will contact the pool wall before the body and the first guide wheel, and the first guide wheel will contact the pool wall before the body. In this way, the pool cleaner is ensured to travel along the pool wall parallel to the first direction, and part of the cleaning portion can contact and rub against the pool wall to improve the cleaning effect on the pool wall. At the same time, when the first guide wheel contacts the pool wall, the body can be prevented from contacting the pool wall to damage the surface of the body, thereby improving the service life of the pool cleaner.

[0019] In some embodiments, the cleaning portion is of a flexible structure. When the pool cleaner cleans the pool wall along the first direction and the cleaning portion abuts against the pool wall and is deformed, there is a gap between the body and the pool wall along the second direction.

[0020] By setting the gap, the cleaning part can better contact the pool wall during rotation, ensuring the cleaning effect on the pool wall, while avoiding the risk of the body and the corresponding position of the front part still rubbing against the pool wall.

[0021] In some embodiments, when the cleaning part abuts against the pool wall and is bent, the first guide wheel contacts and rolls on the pool wall.

[0022] In this way, the pool cleaner can walk along the pool wall parallel to the first direction, and part of the cleaning part can effectively contact and rub against the pool wall after being bent, achieving effective cleaning of the pool wall. At the same time, the first guide wheel can guide the walking of the pool cleaner along the pool wall and limit the contact between the body and the pool wall, thereby further reducing or even eliminating the risk of the body and the corresponding position of the front part still rubbing against the pool wall.

[0023] In some embodiments, the pool cleaner body comprises:

[0024] The body, the accommodation groove is located at the position corresponding to the front part of the body;

[0025] The guide wheel assembly comprises a first guide wheel and a second guide wheel, and the first guide wheel, the second guide wheel and the cleaning part are located on the same side of the body. The first guide wheel is rotatably arranged at the position corresponding to the rear part of the body, and the second guide wheel is rotatably arranged between the first guide wheel and the cleaning part.

[0026] In the second direction:

[0027] At least part of the first guide wheel and at least part of the second guide wheel protrude outward from the body, and part of the cleaning part protrudes outward from the first guide wheel and the second guide wheel.

[0028] In this way, when the pool cleaner contacts the pool wall parallel to the first direction in the second direction, part of the cleaning part will contact the pool wall first, and the first guide wheel and the second guide wheel will contact the pool wall first. In this way, the pool cleaner can walk along the pool wall parallel to the first direction, and part of the cleaning part can contact and rub against the pool wall, improving the cleaning effect on the pool wall. At the same time, when at least one of the first guide wheel and the second guide wheel contacts the pool wall, the body can be prevented from contacting the pool wall and damaging the surface of the body, thereby improving the service life of the pool cleaner.

[0029] In some embodiments, the cleaning part is a flexible structure; when the pool cleaner cleans the pool wall in the first direction, and the cleaning part abuts against the pool wall and is bent, there is a gap between the body and the pool wall in the second direction.

[0030] By setting the gap, the cleaning effect on the pool wall can be ensured, and the risk of the body and the corresponding position of the front part still rubbing against the pool wall can also be reduced.

[0031] In some embodiments, when the cleaning part abuts against the pool wall and is deformed, at least one of the first guide wheel and the second guide wheel contacts and rolls on the pool wall.

[0032] In this way, the pool cleaner can walk along the pool wall parallel to the first direction, and the cleaning part can effectively contact and rub against the pool wall after being deformed, thereby achieving effective cleaning of the pool wall. Meanwhile, when at least one of the first guide wheel and the second guide wheel contacts the pool wall, the pool cleaner can be guided to walk along the pool wall, and the pool cleaner body can be prevented from contacting the pool wall, thereby further reducing or even eliminating the risk that the pool cleaner body still rubs against the pool wall at a position corresponding to the front part.

[0033] In some embodiments, the pool cleaner body comprises:

[0034] the pool cleaner body, and the accommodation slot is located at a position corresponding to the front part of the pool cleaner body;

[0035] the guide wheel assembly comprises a first guide wheel, a second guide wheel, and a third guide wheel, and the first guide wheel, the second guide wheel, and the third guide wheel are located on the same side of the pool cleaner body, wherein the first guide wheel is rotatably arranged at a position corresponding to the rear part of the pool cleaner body, the second guide wheel is rotatably arranged at a position corresponding to the front part of the pool cleaner body, and the third guide wheel is rotatably arranged between the first guide wheel and the second guide wheel;

[0036] In the second direction:

[0037] At least part of the first guide wheel, at least part of the second guide wheel, and at least part of the third guide wheel protrude outward from the pool cleaner body, and part of the cleaning part protrudes outward from the first guide wheel, the second guide wheel, and the third guide wheel.

[0038] In this way, when the pool cleaner contacts the pool wall parallel to the first direction in the second direction, part of the cleaning part will preferentially contact the pool wall, and the first guide wheel, the second guide wheel, and the third guide wheel will preferentially contact the pool wall. In this way, the pool cleaner can walk along the pool wall parallel to the first direction, and part of the cleaning part can contact and rub against the pool wall, thereby improving the cleaning effect on the pool wall. Meanwhile, when at least one of the first guide wheel, the second guide wheel, and the third guide wheel contacts the pool wall, the pool cleaner body can be prevented from contacting the pool wall, thereby improving the service life of the pool cleaner.

[0039] In some embodiments, the cleaning part is a flexible structure, and when the pool cleaner cleans the pool wall in the first direction and the cleaning part abuts against the pool wall and is deformed, there is a gap between the pool cleaner body and the pool wall in the second direction.

[0040] With this gap, the cleaning effect on the pool wall can be ensured, and the risk that the pool cleaner body still rubs against the pool wall at a position corresponding to the front part can be reduced.

[0041] In some embodiments, when the cleaning part abuts against the pool wall and is deformed, at least one of the first guide wheel, the second guide wheel and the third guide wheel is in contact with the pool wall and rolls on the pool wall.

[0042] This ensures that the pool cleaner moves along the pool wall in the first direction and that the cleaning part can effectively contact and rub against the pool wall after being deformed, thereby effectively cleaning the pool wall. When at least one of the first guide wheel, the second guide wheel and the third guide wheel is in contact with the pool wall, the pool cleaner can be guided along the pool wall and the body of the pool cleaner can be prevented from contacting the pool wall, thereby further reducing or even eliminating the risk that the body of the pool cleaner still rubs against the pool wall at a corresponding position of the front part.

[0043] In some embodiments, the pool cleaner body has a propeller assembly for driving the pool cleaner to move;

[0044] The propeller assembly includes at least two propellers, which are symmetrically distributed on both sides of the central axis of the pool cleaner body in the first direction;

[0045] When the cleaning part cleans the pool wall, the total propulsive force of the propellers away from the pool wall is greater than the total propulsive force of the propellers close to the pool wall, so that the resultant force of the propulsive force provided by the propeller assembly to the pool cleaner body is directed towards the pool wall being cleaned. In this way, when the pool cleaner cleans the pool wall in the first direction, the resultant force of the propulsive force presses the pool cleaner against the pool wall, which helps to enhance the cleaning effect of the cleaning part on the pool wall.

[0046] In some embodiments, when the pool cleaner cleans the pool wall in the first direction, the cleaning part is configured to rotate in the first rotation direction, so that the frictional force of the cleaning part on the pool wall is in the same direction as the first direction. In this way, the frictional force of the pool wall on the cleaning part is in the opposite direction to the first direction, which can enhance the cleaning ability of the cleaning part on the pool wall when the pool cleaner cleans the pool wall in the first direction.

[0047] In some embodiments, when the pool cleaner body moves in the first direction along the pool wall, the cleaning part is configured to rotate in the second rotation direction, so that the frictional force of the cleaning part on the pool wall is in the opposite direction to the first direction. In this way, the frictional force of the pool wall on the cleaning part is in the same direction as the first direction, which can assist the pool cleaner to move in the first direction, so as to effectively utilize the electric energy of the pool cleaner and increase the working time of the pool cleaner.

[0048] In a third aspect, the embodiments of the present application provide a pool cleaner, which comprises:

[0049] a pool cleaner body and a cleaning part for cleaning a pool wall;

[0050] The pool cleaner body has a front part and a rear part arranged opposite to each other in the first direction, and the pool cleaner is configured to clean the pool wall in the first direction.

[0051] The pool cleaner body comprises:

[0052] The body is provided with a receiving groove at a position corresponding to the front portion; and

[0053] The first guide wheel is rotatably arranged at a position corresponding to the rear portion of the body;

[0054] The cleaning member comprises a mounting portion and a cleaning portion, the mounting portion is arranged in the receiving groove and is rotatably connected to the body, and the cleaning portion is arranged around the periphery of the mounting portion;

[0055] In the second direction perpendicular to the first direction, the cleaning member and the first guide wheel are located on the same side of the body, at least part of the first guide wheel protrudes outward from the body, and part of the cleaning portion protrudes outward from the first guide wheel.

[0056] The embodiments of the present application limit the positions of the first guide wheel and the cleaning member relative to the body. When the pool cleaner contacts the pool wall parallel to the first direction in the second direction, part of the cleaning portion will contact the pool wall in priority to the body and the first guide wheel, and the first guide wheel will contact the pool wall in priority to the body. In this way, the pool cleaner is ensured to move along the pool wall parallel to the first direction, and part of the cleaning portion can contact and rub against the waterline position on the pool wall, the junction between the pool wall and the pool bottom, and other cleaning positions, thereby improving the cleaning effect on the pool wall. At the same time, when the first guide wheel contacts the pool wall, the body is prevented from contacting the pool wall and damaging the surface of the body, thereby improving the service life of the pool cleaner.

[0057] In some embodiments, the cleaning portion is a flexible structure, and when the pool cleaner cleans the pool wall in the first direction and the cleaning portion abuts against the pool wall and is deformed, there is a gap between the body and the pool wall in the second direction. By providing this gap, the cleaning portion is ensured to better contact the pool wall during rotation, thereby ensuring the cleaning effect on the pool wall, and the risk of the body contacting the pool wall at the position corresponding to the front portion is reduced.

[0058] In some embodiments, when the cleaning portion abuts against the pool wall and is deformed, the first guide wheel contacts the pool wall and rolls on the pool wall. In this way, the pool cleaner is ensured to move along the pool wall parallel to the first direction, and part of the cleaning portion can effectively contact the pool wall and rub against it after being deformed, thereby achieving effective cleaning of the pool wall. At the same time, the first guide wheel has a guiding effect on the movement of the pool cleaner along the pool wall, and can limit the body from contacting the pool wall, thereby further reducing or even eliminating the risk of the body contacting the pool wall at the position corresponding to the front portion.

[0059] In some embodiments, during the process in which the pool cleaner approaches the pool wall in a direction inclined to the pool wall:

[0060] The cleaning part is in contact with the pool wall in advance, and the pool machine body is deflected towards the pool wall while the cleaning part continuously contacts the pool wall until the first guide wheel is in contact with the pool wall.

[0061] In this way, it can be ensured that the cleaning part and the first guide wheel are always in contact with the pool wall during the walking of the pool machine body along the pool wall, so that the pool machine has a good cleaning effect on the pool wall. At the same time, since at least part of the first guide wheel protrudes outward from the machine body in the second direction, the risk of the machine body rubbing against the pool wall at the position corresponding to the front part can be eliminated, and it can be ensured that the machine body is always not in contact with the pool wall during the walking of the pool machine along the pool wall, which can effectively avoid the frictional interference between the machine body and the pool wall, so as to ensure the normal walking of the pool machine along the pool wall and improve the service life of the pool machine.

[0062] In a fourth aspect, the embodiments of the present application provide a pool machine, which comprises:

[0063] a pool machine body and a cleaning part for cleaning the pool wall;

[0064] The pool machine body has a front part and a rear part arranged oppositely in a first direction, and the pool machine is configured to clean the pool wall in the first direction;

[0065] The pool machine body comprises:

[0066] a machine body, the position corresponding to the front part of the machine body is provided with a receiving groove;

[0067] a first guide wheel rotatably arranged at the position corresponding to the rear part of the machine body; and

[0068] a second guide wheel;

[0069] The cleaning part comprises a mounting part and a cleaning part, the mounting part is arranged in the receiving groove and is rotatably connected with the machine body, and the cleaning part is arranged around the periphery of the mounting part.

[0070] In a second direction perpendicular to the first direction, the cleaning part, the first guide wheel and the second guide wheel are located on the same side of the machine body, the second guide wheel is rotatably arranged between the first guide wheel and the cleaning part, at least part of the first guide wheel and at least part of the second guide wheel protrude outward from the machine body, and part of the cleaning part protrudes outward from the first guide wheel and the second guide wheel.

[0071] The embodiments of the present application limit the positions of the first guide wheel, the second guide wheel and the cleaning member relative to the body, so that when the pool cleaner is in contact with the pool wall parallel to the first direction in the second direction, the cleaning part will be in contact with the pool wall in priority to the body, the first guide wheel and the second guide wheel, and the first guide wheel and the second guide wheel will be in contact with the pool wall in priority to the body. In this way, the pool cleaner can walk along the pool wall parallel to the first direction, and the cleaning part can be in contact with the waterline position on the pool wall, the junction of the pool wall and the pool bottom and other cleaning positions to generate friction, thereby improving the cleaning effect on the pool wall. At the same time, when at least one of the first guide wheel and the second guide wheel is in contact with the pool wall, the body can be prevented from being in contact with the pool wall to damage the surface of the body, thereby prolonging the service life of the pool cleaner.

[0072] In some embodiments, the cleaning part is a flexible structure, and when the pool cleaner cleans the pool wall in the first direction and the cleaning part is in contact with the pool wall and deformed, there is a gap between the body and the pool wall in the second direction. Through the provision of the gap, the cleaning effect on the pool wall can be ensured, and the risk that the body and the corresponding position of the front part still rub against the pool wall can be reduced.

[0073] In some embodiments, when the cleaning part is in contact with the pool wall and deformed, at least one of the first guide wheel and the second guide wheel is in contact with the pool wall and rolls on the pool wall. In this way, the pool cleaner can walk along the pool wall parallel to the first direction, and the deformed cleaning part can be in effective contact with the pool wall to generate friction, thereby achieving effective cleaning of the pool wall. At the same time, when at least one of the first guide wheel and the second guide wheel is in contact with the pool wall, the pool cleaner can be guided along the pool wall, and the body can be prevented from being in contact with the pool wall, thereby further reducing or even eliminating the risk that the body and the corresponding position of the front part still rub against the pool wall.

[0074] In some embodiments, during the process in which the pool cleaner approaches the pool wall in a direction inclined to the pool wall:

[0075] The cleaning part is in contact with the pool wall in priority to the body of the pool cleaner, and the body of the pool cleaner is deflected towards the pool wall while the cleaning part continuously contacts the pool wall, until at least one of the first guide wheel and the second guide wheel is in contact with the pool wall.

[0076] In this way, the cleaning part and at least one of the first guide wheel and the second guide wheel can be in contact with the pool wall during the process in which the body of the pool cleaner walks along the pool wall, so that the pool cleaner has a good cleaning effect on the pool wall. At the same time, since at least part of the first guide wheel and at least part of the second guide wheel protrude outwardly from the body in the second direction, the risk that the body and the corresponding position of the front part rub against the pool wall can be eliminated, so that the body is not in contact with the pool wall when the pool cleaner walks along the pool wall, and the body can be effectively prevented from rubbing against the pool wall to ensure the normal walking of the pool cleaner along the pool wall, thereby prolonging the service life of the pool cleaner.

[0077] In a fifth aspect, the embodiments of the present application provide a pool cleaner, which comprises:

[0078] a pool cleaner body and a cleaning member for cleaning a pool wall;

[0079] the pool cleaner body has a front part and a rear part arranged oppositely in a first direction, and the pool cleaner is configured to clean the pool wall along the first direction;

[0080] the pool cleaner body comprises:

[0081] a body, which is provided with a receiving groove at a position corresponding to the front part;

[0082] a first guide wheel, which is rotatably arranged at a position corresponding to the rear part of the body;

[0083] a second guide wheel, which is rotatably arranged at a position corresponding to the front part of the body; and

[0084] a third guide wheel;

[0085] wherein the cleaning member comprises a mounting part and a cleaning part, the mounting part is arranged in the receiving groove and is rotatably connected to the body, and the cleaning part is arranged around a side of the mounting part;

[0086] in a second direction perpendicular to the first direction, the cleaning member, the first guide wheel, the second guide wheel and the third guide wheel are located on the same side of the body, the third guide wheel is rotatably arranged between the first guide wheel and the second guide wheel, at least part of the first guide wheel, at least part of the second guide wheel and at least part of the third guide wheel are convex to the body, and part of the cleaning part is convex to the first guide wheel, the second guide wheel and the third guide wheel.

[0087] The embodiments of the present application limit the positions of the first guide wheel, the second guide wheel and the cleaning member relative to the body, so that when the pool cleaner contacts the pool wall parallel to the first direction in the second direction, part of the cleaning part will contact the pool wall first, and the first guide wheel, the second guide wheel and the third guide wheel will contact the pool wall first than the body. In this way, the pool cleaner can walk along the pool wall parallel to the first direction, and part of the cleaning part can contact and rub the pool wall at the waterline position, the junction of the pool wall and the pool bottom, and other parts to be cleaned, thereby improving the cleaning effect of the pool wall. At the same time, when at least one of the first guide wheel, the second guide wheel and the third guide wheel contacts the pool wall, the body can be prevented from contacting the pool wall and damaging the surface of the body, thereby improving the service life of the pool cleaner.

[0088] In some embodiments, the cleaning portion is a flexible structure; when the pool cleaner moves along the pool wall in the first direction, and the cleaning portion abuts against the pool wall and is deformed, a gap is formed between the cleaner body and the pool wall in the second direction. By providing the gap, the cleaning effect on the pool wall is ensured, and the risk of the cleaner body rubbing against the pool wall at the corresponding position of the front portion is also reduced.

[0089] In some embodiments, when the cleaning portion abuts against the pool wall and is deformed, at least one of the first guide wheel, the second guide wheel, and the third guide wheel contacts and rolls on the pool wall. In this way, the pool cleaner can move along the pool wall in a direction parallel to the first direction, and after part of the cleaning portion is deformed, the cleaning portion can effectively contact and rub against the pool wall, achieving effective cleaning of the pool wall. At the same time, when at least one of the first guide wheel, the second guide wheel, and the third guide wheel contacts the pool wall, it can guide the movement of the pool cleaner along the pool wall and limit the contact between the cleaner body and the pool wall, thereby further reducing or even eliminating the risk of the cleaner body rubbing against the pool wall at the corresponding position of the front portion.

[0090] In some embodiments, during the process in which the pool cleaner approaches the pool wall in a direction inclined to the pool wall:

[0091] The cleaning portion contacts the pool wall first, and while the cleaning portion continuously contacts the pool wall, the cleaner body is deflected towards the pool wall until at least one of the first guide wheel, the second guide wheel, and the third guide wheel contacts the pool wall.

[0092] In this way, it can be ensured that during the movement of the pool cleaner body along the pool wall, the cleaning portion, and at least one of the first guide wheel, the second guide wheel, and the third guide wheel, are always in contact with the pool wall, so that the pool cleaner has a good cleaning effect on the pool wall. At the same time, since at least part of the first guide wheel, at least part of the second guide wheel, and at least part of the third guide wheel protrude outward from the cleaner body in the second direction, the risk of the cleaner body rubbing against the pool wall at the corresponding position of the front portion is eliminated, ensuring that the cleaner body is always in contact with the pool wall during the movement of the pool cleaner along the pool wall, effectively avoiding frictional interference between the cleaner body and the pool wall, to ensure the normal movement of the pool cleaner along the pool wall and improve the service life of the pool cleaner.

[0093] In some embodiments, in the second direction, the cleaning portion protrudes outward from the pool cleaner body by a distance b, and b is greater than 5 mm.

[0094] When b is greater than 5 mm, it can be ensured that the cleaning portion protrudes outward from the pool cleaner body by a larger amount. In this way, during the movement of the pool cleaner along the pool wall in a direction parallel to the first direction and the cleaning of the pool wall, the cleaning portion can be deformed by a larger amount during the contact and friction with the pool wall, to ensure effective contact between the cleaning portion and the pool wall and enhance the cleaning effect.

[0095] In some embodiments, the distance between the cleaning part and the pool cleaner body in the first direction is a, and a is less than b.

[0096] By setting a to be less than b, the cleaning part can better clean the pool wall on the side of the first direction, and when the cleaning part moves with the pool cleaner body and cleans the pool wall parallel to the first direction, the cleaning part can still contact the pool wall more when it is deformed, thus improving the cleaning effect.

[0097] In some embodiments, when the pool cleaner moves forward to clean the pool wall, the linear velocity of the cleaning part at the contact position with the pool wall is in the same direction as the moving direction. In this way, even if the linear velocity of the cleaning part at the contact position with the pool wall is very small, the pool cleaner can still drive the cleaning part to move along the pool wall when moving forward, so that the cleaning part rubs against the pool wall during the movement, thus ensuring the cleaning effect of the cleaning part on the pool wall.

[0098] In some embodiments, the ratio of the linear velocity of the cleaning part at the contact position with the pool wall to the moving speed of the pool cleaner is greater than one-half. In this way, the number of times of rubbing of the cleaning part against the pool wall per unit distance of the pool cleaner can be increased, thus further improving the cleaning effect of the cleaning part on the pool wall.

[0099] In some embodiments, when the pool cleaner moves forward to clean the pool wall, the linear velocity of the cleaning part at the contact position with the pool wall is in the opposite direction of the moving direction, the ratio of the linear velocity of the cleaning part at the contact position with the pool wall to the moving speed of the pool cleaner is greater than 0 and less than or equal to 0.6, or the ratio of the linear velocity of the cleaning part at the contact position with the pool wall to the moving speed of the pool cleaner is greater than 1.3.

[0100] By limiting the ratio of the linear velocity of the cleaning part at the contact position with the pool wall to the moving speed of the pool cleaner to the above range, the difference between the linear velocity of the cleaning part at the contact position with the pool wall and the moving speed of the pool cleaner can be as large as possible, so that the moving speed of the pool cleaner does not offset most of the linear velocity of the contact position with the pool wall, and the cleaning part has a relative friction with the pool wall when rotating in the second direction, thus ensuring the cleaning effect of the cleaning part on the pool wall.

[0136] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0137] Currently, existing pool cleaning machines consist of a body, a roller brush, and a propeller assembly. The propeller assembly is connected to the body and drives it. The roller brush is rotatably mounted on the body. The body contains a filter assembly. As the body moves through the pool water driven by the propeller assembly, the roller brush rotates, scrubbing the pool bottom and walls. This causes impurities on the pool bottom and walls to be trapped in the water flow and drawn into the filter assembly, thus cleaning the pool bottom and walls. However, existing pool cleaning machines have limitations in cleaning the pool walls, especially at the waterline, where they often fail to achieve the desired cleaning effect.

[0138] The waterline refers to the point where the pool wall meets the water surface, the boundary between them. Dirt, grease, and other impurities easily accumulate near the waterline. Keeping the waterline clean is crucial for the overall hygiene and aesthetics of the pool.

[0139] Improving the cleaning effect of pool cleaning machines on pool walls has become a technical problem that needs to be solved.

[0140] In view of this, this application provides a pool cleaning machine, which includes a pool cleaning machine body and a cleaning component. The cleaning component has a cleaning part that can rotate relative to the pool cleaning machine body. When the pool cleaning machine body cleans the pool wall along its first direction, a portion of the cleaning part can contact the pool wall. For example, a portion of the cleaning part can contact the areas on the pool wall that need to be cleaned, including areas on the pool wall that are difficult to clean, such as the waterline. Furthermore, when the cleaning part rotates relative to the pool cleaning machine body, the cleaning part will generate friction with the areas on the pool wall that need to be cleaned, cleaning impurities on the areas so that these impurities are sucked into the pool cleaning machine body, thereby enhancing the cleaning effect of the pool cleaning machine on the pool wall.

[0141] For example, the cleaning component could be a side brush.

[0142] The pool machine body refers to the structure of the pool machine excluding the cleaning components. The structure of the pool machine body will be further described below with reference to the accompanying drawings and embodiments; it will not be repeated here.

[0143] The structure of the swimming pool machine according to the embodiments of this application will be further described below with reference to the accompanying drawings and examples.

[0144] Figures 1 to 4 Structure schematic diagrams of a pool cleaner in different perspectives are respectively shown.

[0145] Referring to Figures 1 to 4 , the pool cleaner comprises a pool cleaner body 100, the pool cleaner body 100 has a front part 12 and a rear part 13 oppositely arranged in a first direction X, and the pool cleaner is configured to clean a pool wall 320 along the first direction X. The first direction X can be understood as the advancing direction of the pool cleaner. The outer side of the pool cleaner body 100 has a receiving groove 11. The outer side of the pool cleaner body 100 refers to the part of the pool cleaner body 100 on one side towards the outside of the pool cleaner body 100.

[0146] Figure 5 A partial exploded view of the pool cleaner in Figure 2 is shown.

[0147] Referring to Figures 1 to 5 , the pool cleaner further comprises a cleaning part 200 for cleaning the pool wall 320. The cleaning part 200 comprises a mounting part 210 and a cleaning part 220, the mounting part 210 is arranged in the receiving groove 11 and is rotationally connected with the pool cleaner body 100. The cleaning part 220 is arranged around the peripheral side of the mounting part 210. Among them, the cleaning part 220 arranged around the peripheral side of the mounting part 210 refers to the cleaning part 220 arranged around the peripheral side of the mounting part 210 and connected with the mounting part 210. In this way, the cleaning part 220 will be rotationally connected with the pool cleaner body 100 through the mounting part 210, so that when the mounting part 210 rotates, the cleaning part 220 can be driven to rotate, so that the cleaning part 200 cleans the pool wall 320 through the cleaning part 220.

[0148] Referring to Figure 5 , the mounting part 210 can comprise a rotating shaft, the rotating shaft is rotationally arranged in the receiving groove 11 to realize the rotational connection between the mounting part 210 and the pool cleaner body 100. When the rotating shaft is arranged in the receiving groove 11, the axis of the rotating shaft is substantially parallel to the thickness direction Z of the pool cleaner body 100. The pool cleaner body 100 has a driving motor therein, the driving motor is connected with the rotating shaft to realize the rotation of the rotating shaft relative to the pool cleaner body 100.

[0149] The cleaning part 220 can comprise a plurality of brush pieces, the plurality of brush pieces are arranged around the peripheral side of the mounting part 210. The cleaning part 220 is directly or indirectly connected with the mounting part 210 through other structural parts. In this application, the connection mode of the cleaning part 220 and the mounting part 210 is not limited.

[0150] Referring to Figure 3 and Figure 4In some embodiments, when the cleaning portion 220 is arranged around the mounting portion 210 and is arranged in the accommodating groove 11 through the mounting portion 210, part of the cleaning portion 220 also protrudes outwardly from the accommodating groove 11. In the embodiments of the present application, the description that A protrudes outwardly from B means that A protrudes outwardly from B and extends outwardly from B. For example, part of the cleaning portion 220 also protrudes outwardly from the accommodating groove 11, which means that part of the cleaning portion 220 also protrudes outwardly from the accommodating groove 11, i.e. when the cleaning portion 220 is arranged in the accommodating groove 11 through the mounting portion 210, part of the cleaning portion 220 also extends outwardly from the accommodating groove 11. In the following, the similar description that A protrudes outwardly from B can be understood in this way.

[0151] Figure 6 A structure diagram of a pool cleaner with only a first guide wheel and a pool wall 320 is shown.

[0152] Referring to Figure 6 When part of the cleaning portion 220 protrudes outwardly from the accommodating groove 11, and when the pool cleaner approaches the pool wall 320 parallel to the first direction X along the second direction Y, the cleaning portion 220 is configured to contact the pool wall 320 before the pool cleaner body 100. The second direction Y is perpendicular to the first direction X. For example, the second direction Y can be the left-right direction of the pool cleaner body 100. In this way, when the pool cleaner travels along the pool wall 320 parallel to the first direction X, the cleaning portion 220 will contact the pool wall 320 before the pool cleaner body 100 and rub against the pool wall 320. When the cleaning portion 220 contacts the waterline position 330 of the pool wall 320 on the pool wall 320, the junction of the pool wall 320 and the pool bottom 310, and other cleaning positions, and the cleaning portion 220 rotates relative to the pool wall 320 under the driving of the mounting portion 210, the cleaning portion 220 will rub against the cleaning positions to clean the impurities on the cleaning positions so that the impurities are sucked into the pool cleaner body 100, thereby enhancing the cleaning effect of the pool cleaner on the pool wall 320.

[0153] It should be noted that "when the pool cleaner approaches the pool wall parallel to the first direction X along the second direction Y" can be that the pool cleaner automatically approaches the pool wall, or that the pool cleaner passively approaches the pool wall through the operation of an operator.

[0154] Referring to Figure 3 and Figure 4In some embodiments, when the cleaning part 220 is arranged around the mounting part 210 and is arranged in the accommodating groove 11 through the mounting part 210, part of the cleaning part 220 protrudes outward from the accommodating groove 11 and the pool cleaner body 100 along the second direction Y, so that part of the cleaning part 220 protrudes outward from the accommodating groove 11 and the pool cleaner body 100 along the second direction Y. In this way, when the pool cleaner approaches the pool wall 320 parallel to the first direction X along the second direction Y, the cleaning part 220 will contact the pool wall 320 before the pool cleaner body 100. When the cleaning part 220 contacts the waterline position 330 on the pool wall 320 and rotates relative to the pool wall 320, the cleaning part 220 can also clean the impurities on the cleaning site, thereby enhancing the cleaning effect of the pool cleaner on the pool wall 320. For details, please refer to the related description in the foregoing, which will not be repeated here.

[0155] The pool cleaner provided by the embodiments of the present application can be an underwater cleaner, a water surface cleaner, or an underwater and water surface integrated cleaner. The underwater cleaner refers to a pool cleaner that can work at the pool bottom 310. The water surface cleaner refers to a pool cleaner that can work on the water surface 340 of the pool. The underwater and water surface integrated cleaner refers to a pool cleaner that can work at the pool bottom 310 and on the water surface 340 of the pool.

[0156] Figure 7a A working scene diagram of a pool cleaner in a pool 300 is shown.

[0157] Referring to Figure 7a When the pool cleaner is a water surface cleaner, part of the pool cleaner can float on the water surface 340 of the pool 300, and can clean the impurities on the water surface 340 of the pool 300 as the pool cleaner moves on the water surface 340. When such a pool cleaner moves towards a pool wall 320 parallel to the first direction X and moves along the pool wall 320 on the water surface 340, the cleaning part 200 arranged on the pool cleaner can contact and rub against the waterline position 330 on the pool wall 320, so as to better clean the waterline position 330 on the pool wall 320.

[0158] Figure 7b A structural schematic diagram of a cleaning part 200 in water is shown.

[0159] Referring to Figure 7b When the cleaning part 200 cleans the waterline position 330 on the pool wall 320, the pool cleaner body 100 can control the floating height of the pool cleaner body 100 in water, so that the waterline position 330 is located between the upper end surface 201 of the cleaning part 200 and the lower end, so that the cleaning part 200 can clean the waterline position 330.

[0160] Figures 1 to 5 A pool cleaner is shown as a water surface cleaner. The following will be described in combination with Figures 1 to 5The structure of the pool cleaner body 100 is described below.

[0161] Referring to Figures 1 to 5 The pool cleaner body 100 includes a body 10, a fishing member 20, a filtering assembly, and a propeller assembly 30. The body 10 has an inlet 16 and an outlet 17. For example, the inlet 16 can be arranged at a position corresponding to the front portion 12 of the body 10, and the outlet 17 can be arranged at the bottom surface 15 of the body 10. The filtering assembly is arranged in the body 10, and the filtering assembly has a filtering cavity. The filtering cavity is in communication with the inlet 16 and the outlet 17, forming a filtering channel. The fishing member 20 is arranged at the inlet 16 and is rotatably connected to the body 10. The body 10 is provided with a receiving groove 11 for accommodating the cleaning member 200. The propeller assembly 30 is connected to the body 10 and drives the body 10 to move. For example, the propeller assembly 30 can be a propeller or a water pump, etc., so as to drive the body 10 to move by means of the propeller or the counter thrust of the water pump.

[0162] When part of the pool cleaner body 100 floats on the water surface 340 of the pool 300 and contacts the pool wall 320 parallel to the first direction X under the driving of the propeller assembly 30, the cleaning member 200 can contact the pool wall 320 and generate friction, so as to loosen or float the impurities on the pool wall 320. When the fishing member 20 rotates relative to the pool cleaner body, water flow is generated. The water flow can assist at least part of the impurities cleaned by the cleaning member 200 to enter the filtering cavity through the inlet 16, and the impurities are trapped in the filtering cavity by the filtering assembly, while the water flow flows through the filtering cavity and the outlet 17 to the outside of the body 10, thereby achieving the cleaning of the pool wall 320 at the waterline position 330.

[0163] Figure 8 Another working scenario of a pool cleaner in a pool 300 is shown.

[0164] Referring to Figure 8 As shown, when the pool cleaner is an underwater cleaner, the pool cleaner can completely sink into the water of the pool 300 to work. When such a pool cleaner moves along the pool wall 320 parallel to the first direction X at the pool bottom 310, the cleaning member 200 arranged on the pool cleaner can contact the junction of the pool wall 320 and the pool bottom 310 and generate friction, so as to better clean the junction of the pool wall 320 and the pool bottom 310. In addition, the pool cleaner body 100 can also move along the pool bottom 310 and clean the pool bottom 310 in the process of moving. Alternatively, the pool cleaner body 100 can also climb on the pool wall 320 and clean the pool wall 320 in the process of climbing.

[0165] Figure 9 Another structure diagram of a pool cleaner is shown. Figure 9The pool cleaner in the present application is an underwater cleaner. The pool cleaner body 100 has a cleaner body 10, a filter assembly and a propeller assembly 30. The difference between the pool cleaner and the surface cleaner is that when the pool cleaner is an underwater cleaner, the inlet 16 and the outlet 17 are arranged differently on the cleaner body 10, and in addition to the cleaner body 10, the filter assembly and the propeller assembly 30, the pool cleaner body 100 further comprises a rolling brush 40. The propeller assembly 30 can be one or a combination of at least two of a propeller, a water pump, a walking wheel and a track.

[0166] The following will be described in combination with Figure 9 The difference between the pool cleaner body 100 when the pool cleaner is an underwater cleaner and the pool cleaner body 100 of the surface cleaner will be briefly described.

[0167] Referring to Figure 9 When the pool cleaner is an underwater cleaner, the inlet 16 is arranged on the bottom surface 15 of the cleaner body 10, the outlet 17 is arranged on the top surface 14 of the cleaner body 10, and the rolling brush 40 is rotatably arranged on the cleaner body 10 at a position corresponding to the front portion 12 or the rear portion 13. When the pool cleaner is cleaning the pool bottom 310 or the pool wall 320 (not the intersection of the pool wall 320 and the pool bottom 310), the rolling brush 40 can rotate and contact the pool bottom 310 or the pool wall 320 during the movement of the pool cleaner, so as to scrub the pool bottom 310 or the pool wall 320, thereby loosening or removing the impurities on the pool bottom 310 or the pool wall 320. At the same time, the rolling brush 40 generates a water flow. Under the action of the water flow and the suction force generated by the cleaner body 10 at the inlet 16, the impurities trapped in the filter cavity are filtered by the filter assembly, and the water flow passes through the filter cavity and the outlet 17 to the outside of the cleaner body 10, thereby achieving the cleaning of the pool wall 320 or the pool bottom 310 by the pool cleaner body 100.

[0168] It should be understood that when the pool cleaner is a surface-underwater integrated cleaner, the pool cleaner will have the functions of both the surface cleaner and the underwater cleaner. That is, the surface-underwater integrated cleaner can work on the water surface 340 to better clean the waterline position 330 on the pool wall 320, and can also sink into the water in the pool 300 to work to better clean the intersection of the pool wall 320 and the pool bottom 310.

[0169] The pool cleaner body 100 of the underwater-surface integrated pool cleaner has at least two liquid inlets 16. One of the liquid inlets 16 is located at a position corresponding to the front portion 12 of the cleaner body 10, and the other liquid inlet 16 is located on the bottom surface 15 of the cleaner body 10. When the underwater-surface integrated pool cleaner is working on the water surface 340, the liquid inlet 16 located at the position corresponding to the front portion 12 of the cleaner body 10 is opened to enable the underwater-surface integrated pool cleaner to clean the waterline position 330 on the pool wall 320 or the pool surface 340. For example, when the underwater-surface integrated pool cleaner is working in the water, the liquid inlet 16 on the bottom surface 15 of the cleaner body 10 is opened to enable the underwater-surface integrated pool cleaner to clean the pool bottom 310 or the pool wall 320.

[0170] Hereinafter, the structure of the pool cleaner will be further described by taking the surface cleaner as an example.

[0171] Referring to Figure 6 A first auxiliary line L1 is constructed on the pool cleaner body 100, and the first auxiliary line L1 is a tangent line of the first point of contact between the pool cleaner body 100 and the pool wall 320 when the pool cleaner contacts the pool wall 320 along the second direction Y and parallel to the first direction X. The first auxiliary line L1 is parallel to the center line o1 of the pool cleaner body 100 in the second direction Y, i.e., the first auxiliary line L1 is parallel to the first direction X. In the projection direction (Z direction) of the thickness of the pool cleaner body 100, the outer edge of the partial cleaning portion 220 extends to the outside of the first auxiliary line L1, and the pool cleaner body 100 is located on the inside of the first auxiliary line L1. By setting the position of the cleaning portion 220 relative to the first auxiliary line L1, it can be ensured that the partial cleaning portion 220 protrudes outwardly from the accommodating groove 11 and the pool cleaner body 100 along the second direction Y.

[0172] It should be noted that, in the present application, "the outer edge of A extends to the outside of the line B in the projection direction of the thickness of the pool cleaner body 100" means that the outer edge of A passes the line B and extends to the side of the line B facing the outside of the pool cleaner body 100 in the projection direction of the thickness of the pool cleaner body 100. Similarly, in the present application, "A is located on the inside of the line B in the projection direction of the thickness of the pool cleaner body 100" means that A is located on the side of the line B facing the inside of the pool cleaner body 100 in the projection direction of the thickness of the pool cleaner body 100, i.e., the outer edge of A does not pass the line B.

[0173] For example, the description that the outer edge of the partial cleaning part 220 extends to the outside of the first auxiliary line L1 in the projection direction of the thickness of the pool cleaner body 100 means that the outer edge of the partial cleaning part 220 goes beyond the first auxiliary line L1 and extends to the side of the first auxiliary line L1 toward the outside of the pool cleaner body 100 in the projection direction of the thickness of the pool cleaner body 100. For another example, the description that the pool cleaner body 100 is located inside the first auxiliary line L1 in the projection direction of the thickness of the pool cleaner body 100 means that the pool cleaner body 100 does not go beyond the first auxiliary line L1 in the projection direction of the thickness of the pool cleaner body 100.

[0174] In the following, the similar descriptions such as "the outer edge of A extends to the outside of B line in the projection direction of the thickness of the pool cleaner body 100" and "A is located inside B line in the projection direction of the thickness of the pool cleaner body 100" will not be explained again.

[0175] Referring to Figure 5 and Figure 6 In some embodiments, the pool cleaner body 100 comprises a body 10, and the accommodating groove 11 is located at the position corresponding to the front part 12 of the body 10. That is, the position corresponding to the front part 12 of the body 10 is provided with the accommodating groove 11. The mounting part 210 is arranged in the accommodating groove 11 and is rotationally connected with the body 10. Since the cleaning part 220 is arranged around the circumferential side of the mounting part 210, the cleaning part 220 can be arranged at the position corresponding to the front part 12 of the body 10, so that the cleaning part 220 of the cleaning member 200 can be in contact with the pool wall 320 opposite to the front part 12 of the pool cleaner body 100 in advance when the pool cleaner body 100 moves in the first direction X, thereby cleaning the pool wall 320.

[0176] The pool cleaner body 100 further comprises a guide wheel assembly. The guide wheel assembly comprises a first guide wheel 50 rotationally arranged at the position corresponding to the rear part 13 of the body 10. For example, the first guide wheel 50 can be connected with the body 10 through the wheel shaft of the first guide wheel 50, so that the first guide wheel 50 is rotationally arranged at the position corresponding to the rear part 13 of the body 10.

[0177] In addition, at least part of the first guide wheel 50 protrudes outwardly from the body 10 in the second direction Y perpendicular to the first direction X. The first guide wheel 50 and the cleaning member 200 are arranged on the same side of the body 10, and at this time, at least part of the cleaning part 220 protrudes outwardly from the first guide wheel 50 in the second direction Y. That is, the cleaning member 200 and the first guide wheel 50 are located on the same side of the body 10 in the second direction Y, at least part of the first guide wheel 50 protrudes outwardly from the body 10, and at least part of the cleaning part 220 protrudes outwardly from the first guide wheel 50.

[0178] By setting the first guide wheel 50 to protrude outward from the body 10 in the second direction Y at least partially, the first guide wheel 50 will constitute the outermost edge of the pool cleaner body 100 in the second direction Y. And when the partial cleaning part 220 also protrudes outward from the first guide wheel 50 in the second direction Y, the partial cleaning part 220 can extend beyond the outermost edge of the pool cleaner body 100 in the second direction Y.

[0179] When the pool cleaner contacts the pool wall 320 parallel to the first direction X in the second direction Y, the partial cleaning part 220 will contact the pool wall 320 first, followed by the body 10 and the first guide wheel 50, and the first guide wheel 50 will contact the pool wall 320 first, followed by the body 10. In this way, when the pool cleaner is running along the pool wall 320 parallel to the first direction X, the partial cleaning part 220 can contact and rub against the pool wall 320 to improve the cleaning effect, and at the same time, when the first guide wheel 50 contacts the pool wall 320, the body 10 can be prevented from contacting the pool wall 320 and damaging the surface of the body 10.

[0180] Therefore, when the pool cleaner is running along the pool wall 320 parallel to the first direction X, by limiting the positions of the first guide wheel 50 and the cleaning part 200 relative to the body 10, the body 10 can be effectively prevented from rubbing against the pool wall 320 to ensure the normal running of the pool cleaner along the pool wall 320 and improve the service life of the pool cleaner.

[0181] The hardness of the cleaning part 220 can be selected according to the design requirements of the pool cleaner.

[0182] Figure 10 A structural schematic diagram of a cleaning part 200 without bending deformation is shown, Figure 11 A structural schematic diagram of a cleaning part 200 after bending deformation is shown.

[0183] Referring to Figure 10 If the hardness of the cleaning part 220 is relatively large and hard, the cleaning part 220 and the first guide wheel 50 can effectively contact the pool wall 320. Referring to Figure 11 If the hardness of the cleaning part 220 is relatively small and soft (for example, the cleaning part 220 is a flexible structure), the cleaning part 220 will undergo a large bending deformation when it contacts and rotates against the pool wall 320, and there is a risk that the body 10 will rub against the pool wall 320 at the position corresponding to the front part 12.

[0184] When the cleaning part 220 is a flexible structure, the pool cleaner moves along the first direction X to clean the pool wall 320, and the cleaning part 220 abuts against the pool wall 320 and is deformed to bend. There is a gap between the pool cleaner body 10 and the pool wall 320 along the second direction Y. Through the gap, the cleaning part 220 can be ensured to better contact the pool wall 320 when rotating, and the cleaning effect on the pool wall 320 can be ensured, and the position corresponding to the front part 12 of the pool cleaner body 10 can be prevented from contacting the pool wall 320, thereby reducing the risk that the position corresponding to the front part 12 of the pool cleaner body 10 still rubs against the pool wall 320.

[0185] Figure 12 A structural diagram of the pool cleaner with only the first guide wheel 50 is shown.

[0186] Referring to Figure 12 When the cleaning part 220 abuts against the pool wall 320 and is deformed to bend, the first guide wheel 50 contacts and rolls on the pool wall 320. In this way, the pool cleaner can move along the pool wall 320 parallel to the first direction X, and part of the cleaning part 220 can be deformed to bend to effectively contact and rub against the pool wall 320, thereby effectively cleaning the pool wall 320. At the same time, the first guide wheel 50 can guide the movement of the pool cleaner along the pool wall 320, and can prevent the pool cleaner body 10 from contacting the pool wall 320, thereby further reducing or even eliminating the risk that the position corresponding to the front part 12 of the pool cleaner body 10 still rubs against the pool wall 320.

[0187] Referring to Figure 11 When the cleaning part 220 abuts against the pool wall 320, the cleaning part 220 is deformed to bend towards one side, and an auxiliary circle 230 is formed by the outer edge of the cleaning part 220 when the cleaning part 220 reaches the maximum bending deformation. In the projection direction of the pool cleaner body 100 in thickness, the outer contour of the auxiliary circle 230 is tangent to the first auxiliary line L1, or the outer contour of the auxiliary circle 230 extends beyond the first auxiliary line L1, that is, the outer contour of the auxiliary circle 230 crosses the first auxiliary line L1. In this way, when the pool cleaner body 100 approaches the pool wall 320 parallel to the first direction X along the second direction Y, the auxiliary circle 230 at least contacts the pool wall 320, and since the pool cleaner body 100 is located on the inner side of the first auxiliary line L1, the cleaning part 220 can contact the pool wall 320 before the pool cleaner body 100 contacts the pool wall 320 when the auxiliary circle 230 contacts the pool wall 320, thereby eliminating the risk that the position corresponding to the front part 12 of the pool cleaner body 10 rubs against the pool wall 320.

[0188] And, a second auxiliary line L2 is constructed on the pool cleaner body 100, the second auxiliary line L2 is the outer common tangent of the same side first guide wheel 50 and the auxiliary circle 230 of the cleaning part 220. When the pool cleaner body 100 walks along the pool wall 320 parallel to the first direction X, the body 10 is arranged on the side of the second auxiliary line L2 away from the pool wall 320. In this way, it can be ensured that at least part of the first guide wheel 50 protrudes outward from the body 10 along the second direction Y, and part of the cleaning part 220 protrudes outward from the first guide wheel 50. In this way, it can be ensured that the pool cleaner has a good cleaning effect on the pool wall 320, and at the same time, when the cleaning part 220 abuts against the pool wall 320 and is bent and deformed, the first guide wheel 50 contacts and rolls on the pool wall 320, and the body 10 has a gap with the pool wall 320.

[0189] In the process of the pool cleaner approaching the pool wall 320 in a direction inclined to the pool wall 320:

[0190] The cleaning part 220 contacts the pool wall 320 first, and at the same time that the cleaning part 220 continuously contacts the pool wall 320, the pool cleaner body 100 is deflected towards the pool wall 320 until the first guide wheel 50 contacts the pool wall 320. That is, in the process that the cleaning part 220 contacts the pool wall 320 and does not leave the pool wall 320, with the deflection of the pool cleaner body 100 towards the pool wall 320, the first guide wheel 50 will contact the pool wall 320, and after the first guide wheel 50 contacts the pool wall 320, the pool cleaner body 100 will no longer be deflected towards the pool wall 320, at this time, the pool cleaner body 100 will walk along the pool wall 320. In this way, it can be ensured that the cleaning part 220 and the first guide wheel 50 are always in contact with the pool wall 320 in the process that the pool cleaner body 100 walks along the pool wall 320, so that the pool cleaner has a good cleaning effect on the pool wall 320. At the same time, since at least part of the first guide wheel 50 protrudes outward from the body 10 along the second direction Y, it can also eliminate the risk of the body 10 and the corresponding position of the front part 12 rubbing against the pool wall 320, and ensure that the body 10 is always not in contact with the pool wall 320 when the pool cleaner walks along the pool wall 320, which can effectively avoid the frictional interference between the body 10 and the pool wall 320, so as to ensure the normal walking of the pool cleaner along the pool wall 320 and improve the service life of the pool cleaner.

[0191] For the convenience of description, the pool cleaner with only the first guide wheel 50 in the above guide wheel assembly is referred to as the first pool cleaner. In some embodiments below, a second pool cleaner and a third pool cleaner are also provided respectively. The structures of the second pool cleaner and the third pool cleaner will be further described below in combination with the drawings and specific embodiments.

[0192] The structure of the second pool cleaner will be introduced first.

[0193] Figure 13A structure diagram of a pool cleaner with only the first guide wheel 50 and the second guide wheel 60 and the pool wall 320 is shown. The second pool cleaner refers to the pool cleaner with only the first guide wheel 50 and the second guide wheel 60. That is, Figure 13 The pool cleaner shown in the middle is the second pool cleaner.

[0194] Referring to Figure 13 In some embodiments, for the second pool cleaner, the pool cleaner body 100 also includes the pool cleaner body 100 and the cleaning piece 200, and the pool cleaner body 100 also includes the body 10, the accommodating groove 11 and the guide wheel assembly provided on the body 10, etc., wherein the structure of the pool cleaner body 100 and the cleaning piece 200, the mounting manner of the cleaning piece 200 on the pool cleaner body 100, and the relative position of the cleaning piece 200 relative to the first auxiliary line L1 are the same as those of the first pool cleaner, which can be referred to the relevant description of the first pool cleaner above, and will not be described here.

[0195] And for the second pool cleaner, due to the introduction of the second guide wheel 60, the setting position of the cleaning piece 200 relative to the body 10 will also be different from that of the first pool cleaner.

[0196] The following Figure 13 , mainly further elaborates the differences between the second pool cleaner and the first pool cleaner.

[0197] Referring to Figure 13 For the second pool cleaner, the guide wheel assembly includes the first guide wheel 50 and the second guide wheel 60, and the first guide wheel 50 and the second guide wheel 60 are provided on the same side of the body 10 as the cleaning piece 200. Specifically, along the second direction Y, the cleaning piece 200, the first guide wheel 50 and the second guide wheel 60 are located on the same side of the body 10. Among them, the first guide wheel 50 is rotatably arranged at a position corresponding to the rear portion 13 of the body 10, and the second guide wheel 60 is rotatably arranged between the first guide wheel 50 and the cleaning piece 200.

[0198] It should be noted that when the first guide wheel 50 and the cleaning piece 200 are provided on the same side of the body 10, the edge line S1 of the side of the cleaning piece 200 away from the first guide wheel 50 and the edge line S2 of the side of the first guide wheel 50 facing the cleaning piece 200 form an interval L. As mentioned above, the second guide wheel 60 is rotatably arranged between the first guide wheel 50 and the cleaning piece 200, which means that the second guide wheel 60 can be rotatably arranged at any position within the interval L.

[0199] As Figure 13 shown, in some embodiments, when the second guide wheel 60 is rotatably arranged between the first guide wheel 50 and the cleaning piece 200, the second guide wheel 60 can be arranged at a position corresponding to the front portion 12 of the body 10.

[0200] Figure 14 Another structure diagram of the pool cleaner with only the first guide wheel 50 and the second guide wheel 60 and the pool wall 320 is shown.

[0201] Referring to Figure 14 In some other embodiments, when the second guide wheel 60 is arranged between the first guide wheel 50 and the cleaning member 200, the second guide wheel 60 can also be arranged at a position corresponding to the area between the body 10 and the front portion 12 and the rear portion 13, i.e. the second guide wheel 60 can also be arranged at a middle area of the body 10 in the first direction X.

[0202] Referring to Figure 13 and Figure 14 in the second direction Y:

[0203] At least part of the first guide wheel 50 and at least part of the second guide wheel 60 are convex to the body 10, and part of the cleaning portion 220 is convex to the first guide wheel 50 and the second guide wheel 60.

[0204] By arranging at least part of the first guide wheel 50 and at least part of the second guide wheel 60 to be convex to the body 10 in the second direction Y, at least one of the first guide wheel 50 and the second guide wheel 60 will constitute the outermost edge of the pool cleaner body 100 in the second direction Y. And when part of the cleaning portion 220 is also convex to the first guide wheel 50 and the second guide wheel 60 in the second direction Y, part of the cleaning portion 220 can extend beyond the outermost edge of the pool cleaner body 100 in the second direction Y.

[0205] When the pool cleaner contacts the pool wall 320 parallel to the first direction X in the second direction Y, part of the cleaning portion 220 will contact the pool wall 320 first than the body 10, the first guide wheel 50 and the second guide wheel 60, and the first guide wheel 50 and the second guide wheel 60 will contact the pool wall 320 first than the body 10. In this way, the pool cleaner can walk along the pool wall 320 parallel to the first direction X, and part of the cleaning portion 220 can contact and rub against the pool wall 320 to improve the cleaning effect on the pool wall 320, and at the same time, when at least one of the first guide wheel 50 and the second guide wheel 60 contacts the pool wall 320, the body 10 can be prevented from contacting the pool wall 320 and damaging the surface of the body 10.

[0206] Therefore, when the pool cleaner walks along the pool wall 320 parallel to the first direction X, by limiting the positions of the first guide wheel 50, the second guide wheel 60 and the cleaning member 200 relative to the body 10, the frictional interference between the body 10 and the pool wall 320 can be effectively avoided to ensure the normal walking of the pool cleaner along the pool wall 320 and improve the service life of the pool cleaner.

[0207] Referring to Figure 13 and Figure 14A third auxiliary line L3 is constructed on the pool cleaner body 100, and the third auxiliary line L3 is an outer common tangent line of the first guide wheel 50 and the second guide wheel 60. In the projection direction of the thickness of the pool cleaner body 100, the partial cleaning part 220 extends to the outside of the third auxiliary line L3, and the body 10 is located on the inside of the third auxiliary line L3. By setting the positions of the body 10 and the cleaning part 220 relative to the third auxiliary line L3, it can be ensured that at least part of the first guide wheel 50, at least part of the second guide wheel 60, and part of the cleaning part 220 protrude outwardly from the body 10 in the second direction Y.

[0208] For the second pool cleaner, the cleaning part 220 can also be selected to have a larger hardness or a smaller hardness. In application, the hardness and size of the cleaning part 220 can be appropriately adjusted according to the needs to ensure that the cleaning part 220 effectively cleans the pool wall 320.

[0209] In some embodiments, for the second pool cleaner, when the cleaning part 220 is a flexible structure, and the pool cleaner cleans the pool wall 320 in the first direction X, and the cleaning part 220 abuts against the pool wall 320 and is deformed, there is also a gap between the body 10 and the pool wall 320 in the second direction Y. By providing this gap, while ensuring the cleaning effect on the pool wall 320, the risk that the position corresponding to the front part 12 of the body 10 still rubs against the pool wall 320 can also be reduced. For details, please refer to the relevant description of the first pool cleaner, which will not be repeated here.

[0210] When the cleaning part 220 abuts against the pool wall 320 and is deformed, at least one of the first guide wheel 50 and the second guide wheel 60 contacts and rolls on the pool wall 320. In this way, it can be ensured that the pool cleaner walks along the pool wall 320 parallel to the first direction X, and part of the cleaning part 220 deforms and effectively contacts and rubs against the pool wall 320 to achieve effective cleaning of the pool wall 320. At the same time, when at least one of the first guide wheel 50 and the second guide wheel 60 contacts the pool wall 320, it can guide the pool cleaner when walking along the pool wall 320, and can limit the body 10 from contacting the pool wall 320, thereby further reducing or even eliminating the risk that the position corresponding to the front part 12 of the body 10 still rubs against the pool wall 320.

[0211] It should be noted that compared to when one of the first guide wheel 50 and the second guide wheel 60 contacts and rolls on the pool wall 320, when both the first guide wheel 50 and the second guide wheel 60 contact and roll on the pool wall 320, the guiding effect of the guide wheel assembly on the pool cleaner when walking along the pool wall 320 can be enhanced, thereby better limiting the body 10 from contacting the pool wall 320, thereby eliminating the risk that the position corresponding to the front part 12 of the body 10 still rubs against the pool wall 320.

[0212] Referring to Figure 13 and Figure 14 , the third auxiliary line L3 can be parallel to the first direction X. At this time, the third auxiliary line L3 can form the above-mentioned first auxiliary line L1. When the outer contour of the auxiliary circle 230 constructed by the cleaning part 220 is tangent to the third auxiliary line L3, or the outer contour of the auxiliary circle 230 extends beyond the third auxiliary line L3 in the projection direction of the thickness of the pool cleaner body 100, the auxiliary circle 230 is constructed by the cleaning part 220. In this way, when the pool cleaner body 100 approaches the pool wall 320 parallel to the first direction X along the second direction Y, the auxiliary circle 230 constructed by the cleaning part 220 is at least tangent to the pool wall 320, and since the body 10 is located on the inner side of the third auxiliary line L3, the cleaning part 220 can contact the pool wall 320 before the body 10 when the auxiliary circle 230 is tangent to the pool wall 320, eliminating the risk that the body 10 and the front part 12 rub against the pool wall 320 at the corresponding position.

[0213] And since the third auxiliary line L3 can be parallel to the first direction X, it can also ensure that when the pool cleaner travels along the pool wall 320 parallel to the first direction X, the first guide wheel 50 and the second guide wheel 60 are both in contact with and roll on the pool wall 320, and in the second direction Y, there is a gap between the body 10 and the pool wall 320.

[0214] It should be noted that in other embodiments, when the pool cleaner body 100 travels along the pool wall 320 parallel to the first direction X, and on the basis of ensuring that the cleaning part 220 can still effectively contact the pool wall 320 when it reaches the maximum bending deformation, the third auxiliary line L3 can also be arranged obliquely relative to the first direction X, so that one of the first guide wheel 50 and the second guide wheel 60 is in contact with and rolls on the pool wall 320.

[0215] In some embodiments, during the process of the pool cleaner approaching the pool wall 320 in a direction inclined to the pool wall 320:

[0216] The cleaning part 220 contacts the pool wall 320 before the pool cleaner body 100, and while the cleaning part 220 continues to contact the pool wall 320, the pool cleaner body 100 is deflected towards the pool wall 320 until at least one of the first guide wheel 50 and the second guide wheel 60 contacts the pool wall 320. That is, during the process of the cleaning part 220 contacting the pool wall 320 and not leaving the pool wall 320, with the deflection of the pool cleaner body 100 towards the pool wall 320, at least one of the first guide wheel 50 and the second guide wheel 60 will contact the pool wall 320, and after at least one of the first guide wheel 50 and the second guide wheel 60 contacts the pool wall 320, the pool cleaner body 100 will no longer be deflected towards the pool wall 320, at which time the pool cleaner body 100 will travel along the pool wall 320.

[0217] In this way, it can be ensured that the cleaning part 220 and at least one of the first guide wheel 50 and the second guide wheel 60 are always in contact with the pool wall 320 during the movement of the pool cleaner body 100 along the pool wall 320, so that the pool cleaner has a better cleaning effect on the pool wall 320. At the same time, since at least part of the first guide wheel 50 and at least part of the second guide wheel 60 protrude outward in the second direction Y, the risk of the machine body 10 rubbing against the pool wall 320 at the position corresponding to the front part 12 can be eliminated, and it can be ensured that the machine body 10 is always not in contact with the pool wall 320 during the movement of the pool cleaner along the pool wall 320. The friction between the machine body 10 and the pool wall 320 can be effectively avoided, so as to ensure the normal movement of the pool cleaner along the pool wall 320 and improve the service life of the pool cleaner.

[0218] The third pool cleaner will be introduced first.

[0219] Figure 15 A structure diagram of a pool cleaner with a first guide wheel 50, a second guide wheel 60, and a third guide wheel 70 and a pool wall 320 is shown. The third pool cleaner refers to a pool cleaner with a first guide wheel 50, a second guide wheel 60, and a third guide wheel 70. That is, Figure 15 The pool cleaner shown in the figure is a third pool cleaner.

[0220] Referring to Figure 15 In some embodiments, for the third pool cleaner, the pool cleaner body 100 also includes the pool cleaner body 100 and the cleaning part 200, and the pool cleaner body 100 also includes the machine body 10, the accommodation groove 11 and the guide wheel assembly provided on the machine body 10, etc. The structure of the pool cleaner body 100 and the cleaning part 200, the mounting manner of the cleaning part 200 on the pool cleaner body 100, and the position of the cleaning part 200 relative to the first auxiliary line L1 are the same as those of the first pool cleaner, and the relevant description of the first pool cleaner can be referred to above, which will not be repeated here.

[0221] In addition, for the third pool cleaner, the positions of the cleaning part 200 relative to the machine body 10 are different from those of the first pool cleaner due to the introduction of the second guide wheel 60 and the third guide wheel 70.

[0222] The differences between the third pool cleaner and the first pool cleaner will be further described below. Figure 15

[0223] Referring to Figure 15 ​For the third pool cleaner, the guide wheel assembly comprises a first guide wheel 50, a second guide wheel 60 and a third guide wheel 70, and the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 are all arranged on the same side of the cleaner body 10. Specifically, along the second direction Y, the cleaning member 200, the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 are all arranged on the same side of the cleaner body 10. Among them, the first guide wheel 50 is rotatably arranged at a position corresponding to the rear part 13 of the cleaner body 10, the second guide wheel 60 is rotatably arranged at a position corresponding to the front part 12 of the cleaner body 10, and the third guide wheel 70 is rotatably arranged between the first guide wheel 50 and the second guide wheel 60.

[0224] When the third pool cleaner approaches the pool wall 320 parallel to the first direction X along the second direction Y, the third guide wheel 70 will contact the pool wall 320 in priority to other structures of the cleaner body 100. The tangent line of the contact point between the third guide wheel 70 and the pool wall 320 forms the first auxiliary line L1.

[0225] Along the second direction Y:

[0226] At least part of the first guide wheel 50, at least part of the second guide wheel 60 and at least part of the third guide wheel 70 all protrude outward from the cleaner body 10, and part of the cleaning part 220 protrudes outward from the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70.

[0227] By arranging at least part of the first guide wheel 50, at least part of the second guide wheel 60 and at least part of the third guide wheel 70 to protrude outward from the cleaner body 10 along the second direction Y, at least one of the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 will constitute the outermost edge of the cleaner body 100 along the second direction Y. And when part of the cleaning part 220 also protrudes outward from the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 along the second direction Y, part of the cleaning part 220 can extend beyond the outermost edge of the cleaner body 100 along the second direction Y.

[0228] When the pool cleaner contacts the pool wall 320 parallel to the first direction X along the second direction Y, part of the cleaning part 220 will contact the pool wall 320 in priority to the cleaner body 10, the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70, while the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 will contact the pool wall 320 in priority to the cleaner body 10. In this way, it is ensured that the pool cleaner can walk along the pool wall 320 parallel to the first direction X, and part of the cleaning part 220 can contact and rub against the pool wall 320 to improve the cleaning effect on the pool wall 320, while when at least one of the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 contacts the pool wall 320, it can also prevent the cleaner body 10 from contacting the pool wall 320 and damaging the surface of the cleaner body 10.

[0229] Therefore, when the pool cleaner moves along the pool wall 320 parallel to the first direction X, by limiting the positions of the first guide wheel 50, the second guide wheel 60, the third guide wheel 70 and the cleaning part 200 relative to the cleaner body 10, the frictional interference between the cleaner body 10 and the pool wall 320 can be effectively avoided, so as to ensure the normal movement of the pool cleaner along the pool wall 320 and improve the service life of the pool cleaner.

[0230] Similarly, the fourth auxiliary line and the fifth auxiliary line can be constructed on the pool cleaner body 100, the fourth auxiliary line is the outer common tangent line of the first guide wheel 50 and the third guide wheel 70, and the fifth auxiliary line is the outer common tangent line of the second guide wheel 60 and the third guide wheel 70. In the projection direction of the thickness of the pool cleaner body 100, the cleaner body 10 is located on the inner side of the fourth auxiliary line and the fifth auxiliary line, so that at least part of the first guide wheel 50, at least part of the second guide wheel 60 and at least part of the third guide wheel 70 protrude outward from the cleaner body 10 along the second direction Y.

[0231] It should be noted that the cleaner body 10 is located on the inner side of the fourth auxiliary line, which means that the cleaner body 10 can be located on the inner side of the fourth auxiliary line as a whole, or the part of the cleaner body 10 located between the first guide wheel 50 and the third guide wheel 70 can be located on the inner side of the fourth auxiliary line. Similarly, the cleaner body 10 located on the inner side of the fifth auxiliary line can also be understood in this way, which will not be repeated here.

[0232] Moreover, in the projection direction of the thickness of the pool cleaner body 100, part of the cleaning part 220 extends to the outer side of the fourth auxiliary line and the fifth auxiliary line, so as to ensure that part of the cleaning part 220 protrudes outward from the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 along the second direction Y.

[0233] For the third pool cleaner, the cleaning part 220 can also be selected to have a larger hardness or a smaller hardness. In application, the hardness and size of the cleaning part 220 can be appropriately adjusted according to requirements, so as to ensure that the cleaning part 220 effectively cleans the pool wall 320.

[0234] In some embodiments, for the third pool cleaner, when the cleaning part 220 is a flexible structure, and the pool cleaner cleans the pool wall 320 along the first direction X, and the cleaning part 220 abuts against the pool wall 320 and is deformed, there is a gap between the cleaner body 10 and the pool wall 320 along the second direction Y. Through the provision of the gap, while ensuring the cleaning effect on the pool wall 320, the risk that the position corresponding to the front part 12 of the cleaner body 10 still rubs against the pool wall 320 can also be reduced. For details, reference can be made to the related description of the first pool cleaner, which will not be repeated here.

[0235] Reference Figure 15When the cleaning portion 220 abuts against the pool wall 320 and is bent, at least one of the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 contacts and rolls on the pool wall 320. In this way, the pool cleaner can effectively contact and rub against the pool wall 320 after the cleaning portion 220 is bent, so as to effectively clean the pool wall 320, and at the same time, when at least one of the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 contacts the pool wall 320, the pool cleaner can be guided along the pool wall 320, and the body 10 can be prevented from contacting the pool wall 320, so as to further reduce or even eliminate the risk that the body 10 and the front portion 12 still rub against the pool wall 320.

[0236] It should be noted that, compared to the case where one of the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 contacts and rolls on the pool wall 320, when at least two of the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 contact and roll on the pool wall 320, the guiding effect of the guide wheel assembly on the pool cleaner when the pool cleaner moves along the pool wall 320 can be enhanced, so as to better prevent the body 10 from contacting the pool wall 320, thereby eliminating the risk that the body 10 and the front portion 12 still rub against the pool wall 320.

[0237] Referring to Figure 15 In some embodiments, when the cleaning portion 220 abuts against the pool wall 320 and is bent, the third guide wheel 70 can contact and roll on the pool wall 320, while the first guide wheel 50 and the second guide wheel 60 do not contact the pool wall 320. In this way, the third guide wheel 70 can guide the pool cleaner when the pool cleaner moves along the pool wall 320, and can prevent the body 10 from contacting the pool wall 320, thereby further reducing or even eliminating the risk that the body 10 and the front portion 12 still rub against the pool wall 320. At this time, the first auxiliary line L1 can also be the external common tangent line of the auxiliary circle 230 formed by the cleaning portion 220 and the third guide wheel 70.

[0238] In some embodiments, the fourth auxiliary line can be parallel to the first direction X. At this time, the fourth auxiliary line can form the first auxiliary line L1, i.e., when the pool cleaner body 100 approaches the pool wall 320 parallel to the first direction X along the second direction Y, the first guide wheel 50 and the third guide wheel 70 simultaneously contact the pool wall 320. Moreover, along the projection direction of the thickness of the pool cleaner body 100, the outer contour of the auxiliary circle 230 constructed by the cleaning part 220 is tangent to the fourth auxiliary line, or the outer contour of the auxiliary circle 230 extends beyond the fourth auxiliary line. In this way, when the pool cleaner body 100 approaches the pool wall 320 parallel to the first direction X along the second direction Y, the auxiliary circle 230 constructed by the cleaning part 220 is at least tangent to the pool wall 320, and since the body 10 is located on the inner side of the fourth auxiliary line, the cleaning part 220 can contact the pool wall 320 before the pool cleaner body 100 when the auxiliary circle 230 is tangent to the pool wall 320, eliminating the risk that the body 10 and the front part 12 rub against the pool wall 320 at the corresponding position.

[0239] Moreover, since the fourth auxiliary line can be parallel to the first direction X, it can also ensure that when the pool cleaner travels along the pool wall 320 parallel to the first direction X, the first guide wheel 50 and the third guide wheel 70 are both in contact with and roll on the pool wall 320, and along the second direction Y, there is a gap between the body 10 and the pool wall 320.

[0240] Similarly, the fifth auxiliary line can also be parallel to the first direction X, at this time, the fifth auxiliary line can form the first auxiliary line L1, i.e., when the pool cleaner body 100 approaches the pool wall 320 parallel to the first direction X along the second direction Y, the second guide wheel 60 and the third guide wheel 70 simultaneously contact the pool wall 320. Moreover, along the projection direction of the thickness of the pool cleaner body 100, the outer contour of the auxiliary circle 230 constructed by the cleaning part 220 is tangent to the fifth auxiliary line, or the outer contour of the auxiliary circle 230 extends beyond the fifth auxiliary line. In this way, when the pool cleaner body 100 approaches the pool wall 320 parallel to the first direction X along the second direction Y, the auxiliary circle 230 constructed by the cleaning part 220 is at least tangent to the pool wall 320, and since the body 10 is located on the inner side of the fifth auxiliary line, the cleaning part 220 can contact the pool wall 320 before the pool cleaner body 100 when the auxiliary circle 230 is tangent to the pool wall 320, eliminating the risk that the body 10 and the front part 12 rub against the pool wall 320 at the corresponding position.

[0241] Moreover, since the fifth auxiliary line can also be parallel to the first direction X, it can ensure that when the pool cleaner travels along the pool wall 320 parallel to the first direction X, the second guide wheel 60 and the third guide wheel 70 are both in contact with and roll on the pool wall 320, and along the second direction Y, there is a gap between the body 10 and the pool wall 320.

[0242] It should be noted that in some embodiments, the fourth auxiliary line and the fifth auxiliary line can coincide (i.e. be collinear), and are both parallel to the first direction X. In this way, while ensuring that the pool cleaner has a good cleaning effect on the pool wall 320, it can also ensure that when the pool cleaner travels along the pool wall 320 in a direction parallel to the first direction X, the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 are all in contact with and roll on the pool wall 320, and there is a gap between the pool cleaner body 10 and the pool wall 320 in the second direction Y.

[0243] Referring to Figure 15 In some embodiments, during the process in which the pool cleaner approaches the pool wall 320 in a direction inclined to the pool wall 320:

[0244] The cleaning part 220 contacts the pool wall 320 first, and while the cleaning part 220 continues to contact the pool wall 320, the pool cleaner body 100 is deflected towards the pool wall 320 until at least one of the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 contacts the pool wall 320. That is, during the process in which the cleaning part 220 contacts the pool wall 320 and does not leave the pool wall 320, with the deflection of the pool cleaner body 100 towards the pool wall 320, at least one of the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70 will contact the pool wall 320, and after at least one of the first guide wheel 50 and the second guide wheel 60 contacts the pool wall 320, the pool cleaner body 100 will no longer be deflected towards the pool wall 320, at which time the pool cleaner body 100 will travel along the pool wall 320.

[0245] This can ensure that the cleaning part 220, and at least one of the first guide wheel 50, the second guide wheel 60 and the third guide wheel 70, are always in contact with the pool wall 320 during the process in which the pool cleaner body 100 travels along the pool wall 320, so that the pool cleaner has a good cleaning effect on the pool wall 320. At the same time, since at least part of the first guide wheel 50, at least part of the second guide wheel 60 and at least part of the third guide wheel 70 all protrude outward from the pool cleaner body 10 in the second direction Y, the risk of the pool cleaner body 10 and the front part 12 rubbing against the pool wall 320 at a position corresponding to the pool cleaner body 10 can be eliminated, and the pool cleaner body 10 can always be ensured to not contact the pool wall 320 when the pool cleaner travels along the pool wall 320, which can effectively avoid frictional interference between the pool cleaner body 10 and the pool wall 320, so as to ensure the normal travel of the pool cleaner along the pool wall 320 and improve the service life of the pool cleaner.

[0246] Figure 16 A size of a pool cleaner is schematically shown Figure 1 .

[0247] Referring to Figure 16In some embodiments, the cleaning portion 220 protrudes outward from the pool cleaner body 100 by a distance b in the second direction Y, and b is greater than 5 mm. The dimension b is applicable to any of the pool cleaner bodies 100 described above. For example, b can be 6 mm, 7 mm, 9 mm, 10 mm, etc.

[0248] When b is greater than 5 mm, the cleaning portion 220 can protrude outward from the pool cleaner body 100 by a larger distance, which can ensure that the cleaning portion 220 can deform more when the cleaning portion 220 contacts and rubs against the pool wall 320 when the pool cleaner moves along the pool wall 320 in the first direction X, thereby enhancing the cleaning effect of the cleaning portion 220 on the pool wall 320.

[0249] In some embodiments, the cleaning portion 220 protrudes outward from the pool cleaner body 100 by a distance a in the first direction X, and a is less than b. The relationship between the dimensions a and b is also applicable to any of the pool cleaner bodies 100 described above. For example, when b can be 9 mm, a can be 8 mm, 7.5 mm, 7.1 mm, 7.0 mm, 6.8 mm, etc.

[0250] Since the pool cleaner body 100 moves in the first direction X under the action of a propelling force such as a propeller assembly 30 (e.g., a screw propeller or a water pump), the cleaning portion 220 has a better propelling force effect in the first direction X than in the second direction Y, which can ensure that the cleaning portion 220 can clean the pool wall 320 on the side of the first direction X when the pool cleaner body 100 moves along the pool wall 320 in the second direction Y.

[0251] Therefore, by setting a to be less than b, the cleaning portion 220 can clean the pool wall 320 on the side of the first direction X while ensuring that the cleaning portion 220 can contact the pool wall 320 more when the cleaning portion 220 deforms and bends when the pool cleaner body 100 moves along the pool wall 320 in the first direction X, thereby enhancing the cleaning effect of the cleaning portion 220 on the pool wall 320.

[0252] Figure 17 A size diagram of a pool cleaner is shown Figure 2 .

[0253] Referring to Figure 17In some embodiments, the distance between the cleaning portion 220 and the body 10 in the second direction Y is c, and c is greater than b. The relationship between the sizes of c and b also applies to the body 100 of any of the pool cleaners described above. For example, when b can be 9 mm, c can be 10 mm, 11 mm, 12 mm, 13 mm, etc. When the guide wheels in the guide wheel assembly contact and roll on the pool wall 320, the gap between the body 10 and the pool wall 320 can be less than or equal to c.

[0254] By setting c to be greater than b, the cleaning portion 220 has a greater protrusion than the body 10 in the second direction Y, so that when the cleaning portion 220 contacts and deforms on the pool wall 320, the body 10 can have a gap with the pool wall 320 to avoid friction between the body 10 and the pool wall 320.

[0255] It should be noted that the above only describes the structure of the cleaning member 200 and the guide wheel assembly on one side of the pool cleaner in the second direction Y. Along the center line o1 of the pool cleaner in the second direction Y, the pool cleaner also has a symmetric structure of the cleaning member 200 and the guide wheel assembly on the other side of the pool cleaner in the second direction Y, that is, the pool cleaner has a symmetric structure in the second direction Y.

[0256] Figure 18 Another structure of a pool cleaner is shown.

[0257] Referring to Figure 18 As described above, the pool cleaner body 100 has a propeller assembly 30. The propeller assembly 30 is used to drive the pool cleaner to move. The propeller assembly 30 includes at least two propellers 31 symmetrically distributed on both sides of the center axis of the pool cleaner body 100 in the first direction X. Figure 18 The propeller assembly 30 with two propellers 31 is shown in the middle. In some embodiments, the propeller assembly 30 can also have other numbers of propellers 31. The propeller 31 can be a propeller, a water pump, a track, a walking wheel, etc. as described above.

[0258] In some embodiments, when the cleaning member 200 cleans the pool wall 320, the total propulsive force of the propeller 31 away from the pool wall 320 is greater than the total propulsive force of the propeller 31 close to the pool wall 320, so that the propeller assembly 30 provides a resultant force of the propulsive force to the pool cleaner body 100 towards the pool wall 320 being cleaned. In this way, when the pool cleaner cleans the pool wall 320 in the first direction X, the resultant force of the propulsive force presses the pool cleaner on the pool wall 320, which helps to enhance the cleaning effect of the cleaning member 200 on the pool wall 320.

[0259] The control of the total propulsive force of the propeller 31 is described below by taking the propeller 31 as a water pump,

[0260] When the propeller 31 is a water pump or the like, the total power of the water pump far from the pool wall 320 side can be controlled to be greater than the total power of the water pump close to the pool wall 320 side, so as to ensure that when the cleaning member 200 cleans the pool wall 320, the total propulsion force of the propeller 31 far from the pool wall 320 side is greater than the total propulsion force of the propeller 31 close to the pool wall 320 side.

[0261] Figure 19 A schematic diagram of the rotation direction of the cleaning member 200 when the pool cleaner cleans the pool wall 320 is shown.

[0262] Referring to Figure 19 In some embodiments, when the pool cleaner cleans the pool wall 320 in the first direction X, the cleaning member 200 is configured to rotate in the first rotation direction W, so that the friction force f of the cleaning member 200 on the pool wall 320 is the same as the first direction X. In this way, the friction force of the pool wall 320 on the cleaning member 200 will be opposite to the first direction X, which can enhance the cleaning ability of the cleaning member 200 on the pool wall 320 when the pool cleaner cleans the pool wall 320 in the first direction X.

[0263] Figure 20 Another schematic diagram of the rotation direction of the cleaning member 200 when the pool cleaner cleans the pool wall 320 is shown.

[0264] Referring to Figure 20 In other embodiments, when the pool cleaner body 100 advances along the pool wall 320 in the first direction X, the cleaning member 200 is configured to rotate in the second rotation direction V, so that the friction force f of the cleaning member 200 on the pool wall 320 is opposite to the first direction X. In this way, the friction force of the pool wall 320 on the cleaning member 200 will be the same as the first direction X, which can assist the pool cleaner to walk in the first direction X, so as to effectively utilize the electric energy of the pool cleaner and improve the working time of the pool cleaner.

[0265] Figure 19 And Figure 20 For the two different working modes of the cleaning member 200, the user can select one of the working modes according to the needs.

[0266] Referring to Figure 20 In some embodiments, when the pool cleaner walks forward to clean the pool wall 320, the linear velocity direction μ of the cleaning member 200 at the position of contact with the pool wall 320 is the same as the walking direction. In this way, although the linear velocity of the cleaning member 200 at the position of contact with the pool wall 320 is very small (for example, the linear velocity tends to be 0), the cleaning member 200 will also walk along the pool wall 320 when the pool cleaner walks forward, so that the cleaning member 200 rubs the pool wall 320 in the process of walking, ensuring the cleaning effect of the cleaning member 200 on the pool wall 320.

[0267] When the pool cleaner moves forward to clean the pool wall 320, the cleaning member 200 rotates in the first rotation direction W, and the linear velocity direction μ of the cleaning member 200 at the contact position with the pool wall 320 is the same as the moving direction of the pool cleaner.

[0268] When the linear velocity direction μ of the cleaning member 200 at the contact position with the pool wall 320 is the same as the moving direction of the pool cleaner, in some embodiments, the ratio of the linear velocity of the cleaning member 200 at the contact position with the pool wall 320 to the moving speed of the pool cleaner can be greater than one half. For example, the ratio of the linear velocity of the cleaning member 200 at the contact position with the pool wall 320 to the moving speed of the pool cleaner can be two thirds, or one. In this way, the number of times of friction between the cleaning member 200 and the pool wall 320 per unit moving distance of the pool cleaner can be increased, and the cleaning effect of the cleaning member 200 on the pool wall 320 can be further enhanced.

[0269] Referring to Figure 20 In some embodiments, when the pool cleaner moves forward to clean the pool wall 320, the linear velocity direction μ of the cleaning member 200 at the contact position with the pool wall 320 is opposite to the moving direction of the pool cleaner. When the linear velocity direction μ of the cleaning member 200 at the contact position with the pool wall 320 is opposite to the moving direction of the pool cleaner, the ratio of the linear velocity of the cleaning member 200 at the contact position with the pool wall 320 to the moving speed of the pool cleaner is greater than 0 and less than or equal to 0.6, or the ratio of the linear velocity of the cleaning member 200 at the contact position with the pool wall 320 to the moving speed of the pool cleaner is greater than 1.3. For example, the ratio of the linear velocity of the cleaning member 200 at the contact position with the pool wall 320 to the moving speed of the pool cleaner can be 0.2, 0.4, 0.5, 1.4, 1.5, etc.

[0270] If the linear velocity direction μ of the cleaning member 200 at the contact position with the pool wall 320 is opposite to the moving direction of the pool cleaner, and the linear velocity of the cleaning member 200 at the contact position with the pool wall 320 is close to the moving speed of the pool cleaner, the moving speed of the pool cleaner will offset most of the linear velocity at the contact position with the pool wall 320, which will cause that although the cleaning member 200 rotates in the second rotation direction V, there is no relative friction force between the cleaning member 200 and the pool wall 320, and the cleaning effect of the cleaning member 200 on the pool wall 320 is seriously affected.

[0271] By limiting the ratio of the linear velocity of the cleaning member 200 at the contact position with the pool wall 320 to the moving speed of the pool cleaner within the above range, the difference between the linear velocity of the cleaning member 200 at the contact position with the pool wall 320 and the moving speed of the pool cleaner can be as large as possible, so as to avoid that the moving speed of the pool cleaner offsets most of the linear velocity at the contact position with the pool wall 320, and ensure that the cleaning member 200 has a relative friction force with the pool wall 320 when the cleaning member 200 rotates in the second rotation direction V, and the cleaning effect of the cleaning member 200 on the pool wall 320 is ensured.

[0272] It should be noted that when the cleaning piece 200 rotates along the second rotation direction V, the pool cleaner will walk forward to clean the pool wall 320, and the linear velocity direction μ of the contact position of the cleaning piece 200 and the pool wall 320 is opposite to the walking direction.
