[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] With people placing increasing importance on exercise, more and more people are choosing swimming, making swimming pools a primary venue for swimming. After a period of use, pool walls and bottoms are prone to accumulating dirt, thus requiring regular cleaning. To save on labor and time costs, pool cleaning machines are typically used for pool cleaning.

[0027] As mentioned in the background section, when a pool cleaner is placed underwater, water from the pool can easily enter the cleaner due to water pressure. Related technologies employ sealing structures at the seams of the pool cleaner's outer casing to seal the internal chambers. However, because pool cleaners have multiple mechanisms for performing their functions, such as cameras, ultrasonic or infrared sensors, the waterproofing at these locations is often inadequate, still causing the pool cleaner to malfunction due to water ingress.

[0028] Based on the above, the applicant of this application has proposed a technical solution in the embodiments of this application. Specifically, by implementing a sealing design at the locations of various functional mechanisms on the pool cleaning machine, the sealing degree of the pool cleaning machine is improved, thereby ensuring that the pool cleaning machine can be used normally underwater and further extending its service life.

[0029] The above is the core idea of ​​this application. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1 , Figure 2 As shown in the figure, this application embodiment provides a swimming pool cleaning machine, which includes a housing 1, and an installation chamber is formed inside the housing 1. Each mechanism of the swimming pool cleaning machine for realizing its corresponding function is disposed inside the installation chamber, and the housing 1 has at least one opening, which communicates with the installation chamber. Furthermore, at least one sensor is also disposed on the housing 1, and the sensor is sealed to the opening.

[0031] In summary, the swimming pool cleaning machine provided in this application embodiment achieves a sealed fit between the sensor installed on the housing 1 and the opening on the housing 1, ensuring a sealing effect between the sensor and the opening while fulfilling its own function. This, to a certain extent, prevents water from entering the opening when the swimming pool cleaning machine is working, thus ensuring the normal underwater use of the swimming pool cleaning machine and further extending its service life.

[0032] like Figure 2 As shown, in some embodiments, the sensor further includes a camera mechanism 2, an ultrasonic detection mechanism 3, and an infrared detection mechanism 4.

[0033] The camera module 2 is capable of capturing images of the pool's internal environment. For example, the pool cleaner can use camera 22 to identify the pool's boundaries, steps, and other locations, thereby creating a work map for more efficient cleaning path planning. Additionally, camera module 2 can capture the location of obstacles in the water in real time, dynamically adjusting the route or pausing operation based on the acquired image information to prevent the equipment from getting stuck or damaged.

[0034] The ultrasonic detection mechanism 3 can calculate distance by measuring the sound wave reflection time, thereby achieving a detection function. For example, by emitting ultrasonic waves and receiving the echoes, it can detect the distance between the pool cleaner and obstacles such as pool walls or steps, thus adjusting the path in advance or slowing down to avoid collisions and prevent the equipment from getting stuck or damaged. In addition, the ultrasonic detection mechanism 3 can also identify changes in the shape and depth of the pool, thereby adjusting the cleaning intensity or its own weight.

[0035] The infrared detection mechanism 4 can detect obstacles in front of or around the pool cleaner by emitting infrared rays and receiving reflected signals, thereby achieving precise obstacle avoidance. Furthermore, infrared detection is more sensitive to small objects at close range (such as toys and debris), compensating for the limitations of ultrasonic waves in detecting short-range or complex-shaped objects.

[0036] Based on this, the aforementioned openings specifically include a first opening 110, a second opening 120, and a third opening 130. The camera assembly 2 is disposed within the mounting cavity and located at the first opening 110. Furthermore, a first sealing element 21 is provided between the camera assembly 2 and the housing 1 to ensure a sealed fit between the camera assembly 2 and the first opening 110. In this way, the pool cleaning machine can ensure a sealing effect at the location where the camera assembly 2 is installed, preventing water from the pool from entering the housing 1 or the camera assembly 2 through the first opening 110.

[0037] Furthermore, the ultrasonic detection mechanism 3 is disposed within the installation chamber and located at the second opening 120. A second sealing element 31 is provided between the ultrasonic detection mechanism 3 and the housing 1 to ensure a sealed fit between the ultrasonic detection mechanism 3 and the second opening 120. In this way, the pool cleaning machine can ensure a sealing effect at the location where the ultrasonic detection mechanism 3 is installed, preventing water from the pool from entering the housing 1 or the ultrasonic detection mechanism 3 through the second opening 120.

[0038] Furthermore, the infrared detection mechanism 4 is disposed within the installation chamber and located at the third opening 130. A third sealing element 41 is provided between the infrared detection mechanism 4 and the housing 1 to ensure a sealed fit between the infrared detection mechanism 4 and the third opening 130. In this way, the pool cleaning machine can guarantee a sealing effect at the location where the infrared detection mechanism 4 is installed, preventing water from the pool from entering the housing 1 or the infrared detection mechanism 4 through the third opening 130.

[0039] like Figure 3 As shown, in some embodiments, the camera mechanism 2 includes a camera 22 and a first mounting base 23. The end face of the first mounting base 23 is provided with a first mounting hole 231, and the camera 22 is disposed in the first mounting hole 231.

[0040] The first mounting base 23 is disposed inside the housing 1 at the location of the first opening 110. The camera 22 can be mounted in the mounting cavity formed by the first mounting base 23 and can be exposed from the first mounting hole 231, thereby enabling it to take pictures and acquire image information of the external environment. For example, the first opening 110 of the housing 1 has a mounting portion 11 protruding outward toward the outside of the housing 1, and the camera mechanism 2 can extend to the location of the mounting portion 11.

[0041] Furthermore, the first mounting base 23 is located at the first opening 110 and is sealed to the first opening 110. This ensures the sealing performance between the first mounting base 23 and the first opening 110, preventing water from the pool from flowing into the mounting chamber through the space between the first mounting base 23 and the first opening 110. Specifically, the sealing fit between the first mounting base 23 and the first opening 110 can be achieved by an interference fit, ensuring a tight seal at the contact points.

[0042] Based on the above, the first mounting hole 231 is positioned opposite the first opening 110, and a cover plate 5 is provided on the inner side of the first opening 110. The first sealing element 21 is a sealing ring, which is sandwiched between the end face and the cover plate 5. In this way, the position of the first mounting hole 231 on the first mounting base 23 and the first opening 110 are also sealed by the sealing ring. Water in the pool will not enter the position of the camera 22 through the first mounting hole 231, thereby further ensuring the sealing effect at the camera 22 and thus further ensuring the normal use of the camera mechanism 2.

[0043] like Figure 3 As shown, in one specific embodiment, a first annular sealing groove 232 is provided on the end face of the first mounting base 23. The first annular sealing groove 232 is arranged around the outside of the first mounting hole 231. A part of the first sealing member 21 is disposed in the first annular sealing groove 232, and the other part of the first sealing member 21 extends out of the first annular sealing groove 232 and is interference-fitted with the cover plate 5. By providing the annular sealing groove, the first sealing member 21 is limited, so that the first sealing member 21 will not shift after being squeezed, thus ensuring the sealing effect. On this basis, the other part of the first sealing member 21 extends out of the first annular sealing groove 232 and is interference-fitted with the cover plate 5. That is to say, the first sealing member 21 is squeezed between the first annular sealing groove 232 and the cover plate 5, thereby sealing the gap between the two by generating a certain degree of deformation, achieving a better sealing effect.

[0044] like Figure 3 As shown, based on the above, in some embodiments, the camera mechanism 2 further includes an annular pressure cap 24. The annular pressure cap 24 includes a cap body 241 and a first flange 242. The cap body 241 is arranged around the outer periphery of the first mounting base 23 and abuts against the inner edge of the first opening 110. The first flange 242 extends towards the center of the first opening 110. Furthermore, the first flange 242 abuts against the side of the cover plate 5 opposite to the first seal 21. The annular pressure cap 24 can provide a pressure effect on the cover plate 5; that is, the first flange 242 of the annular pressure cap 24 blocks the side of the cover plate 5 opposite to the first seal 21. Thus, the annular pressure cap 24 can further compress the first seal 21, resulting in greater deformation of the first seal 21 and a better sealing effect between the first mounting base 23 and the cover plate 5.

[0045] In a specific implementation, since the first opening 110 has a mounting portion 11 that allows the camera to protrude outwards, the shape of the annular cover 24 can match the shape of the mounting portion 11. For example, the annular cover 24 also includes a second flange 243. The cover body 241 is circumferentially disposed on the outer periphery of the first mounting base 23. The first flange 242 is disposed at one end of the cover body 241 near the first opening 110, and the second flange 243 is disposed at one end of the cover body 241 away from the first opening 110. In this case, the second flange 243 abuts against the inner edge of the first opening 110.

[0046] This configuration not only presses the cover plate 5 down through the first flange 242, but also secures the annular pressing root relative to the mounting portion 11 through the second flange 243, preventing relative movement of the annular pressing cover 24. For example, the annular pressing cover 24 can be a one-piece structure to ensure structural strength. The shape of the pressing cover body 241 matches that of the mounting portion 11 to ensure a stable and reliable connection between the two.

[0047] In addition, it should be noted that the sealing fit between the first mounting base 23 and the first opening 110 can specifically be an interference fit between the annular gland 24 and the first opening 110.

[0048] like Figure 4 and Figure 5 As shown, in some embodiments, the ultrasonic detection mechanism 3 includes an ultrasonic sensor 32 and a second mounting base 33. A second mounting hole 331 is formed on the second mounting base 33, and the ultrasonic sensor 32 is disposed in the second mounting hole 331. The second mounting base 33 is positioned at the location corresponding to the second opening 120 of the mounting chamber. Specifically, the second mounting base 33 can be fitted onto the second opening 120 to achieve the installation of the ultrasonic detection mechanism 3.

[0049] In some embodiments, multiple ultrasonic detection mechanisms 3 can be provided as needed. When there are multiple ultrasonic detection mechanisms 3, multiple second openings 120 are correspondingly opened on the housing 1, with each ultrasonic detection mechanism 3 located at a corresponding second opening 120. Based on this, the second mounting bases 33 of all ultrasonic detection mechanisms 3 can be multiple independent ones, which facilitates the independent replacement of each mechanism, or all ultrasonic detection mechanisms 3 can be integrated into a single structure, which enables rapid assembly.

[0050] In addition, when the ultrasonic detection mechanism 3 and the camera mechanism 2 are set close to each other, the first mounting base 23 and the second mounting base 33 can also be set as an integral structure, which can not only achieve faster assembly, but also reduce the number of openings on the surface of the housing 1. This not only facilitates the production and molding of the housing 1, but also further ensures the structural strength of the housing 1.

[0051] Furthermore, the second mounting base 33 is located at the second opening 120 and is sealed to the second opening 120. The second sealing element 31 is a sealing ring, which is sandwiched between the ultrasonic sensor 32 and the hole wall of the second mounting hole 331.

[0052] The sealing fit between the second mounting base 33 and the second opening 120 ensures a tight seal, preventing water from the pool from flowing into the mounting chamber through this gap. Specifically, the sealing fit between the second mounting base 33 and the second opening 120 can be achieved by an interference fit, ensuring a tight seal at the contact points.

[0053] Based on this, the sealing ring is sandwiched between the ultrasonic sensor 32 and the hole wall of the second mounting hole 331, which can also seal the second mounting hole 331. In this way, water in the pool will not enter the ultrasonic sensor 32, thereby further ensuring the sealing effect of the ultrasonic detection mechanism 3 itself, and thus further ensuring the normal use of the ultrasonic detection mechanism 3.

[0054] like Figure 4 and Figure 5 As shown, in one specific embodiment, an abutment 332 is formed on the wall of the second mounting hole 331. An abutment surface is formed on the side of the abutment 332 facing the outside of the housing 1, and the ultrasonic sensor 32 abuts against this abutment surface. In other words, the ultrasonic sensor 32 is fixed relative to the second mounting base 33 by abutting against the abutment surface on the abutment 332, preventing the ultrasonic sensor 32 from moving relative to the second mounting hole 331.

[0055] Based on this, an annular gap 30 is formed between the ultrasonic sensor 32 and the hole wall of the second mounting hole 331, and a second annular sealing groove 433333 is formed on the abutting surface. The second annular sealing groove 433333 is located close to the hole wall of the second mounting hole 331, and the second annular sealing groove 433333 communicates with the annular gap 30. A part of the second sealing member 31 is located in the second annular sealing groove 433333, and another part of the second sealing member 31 extends into the annular gap 30.

[0056] As can be seen, the second seal 31 not only seals the annular gap 30 between the ultrasonic sensor 32 and the second mounting hole 331, but also extends further into the second annular sealing groove 433333. This not only provides better fixation and sealing for the ultrasonic sensor 32 within the second mounting hole 331, but also achieves better sealing of the annular gap 30 through the second annular sealing groove 433333. Simultaneously, the second annular sealing groove 433333 also serves as a limiting element for the second seal 31. In practice, the second seal 31 can be, for example, a rubber gasket or a silicone gasket.

[0057] Furthermore, when setting the second seal 31, the height of the second seal 31 can be the same as the distance from the abutment surface to the opening of the second mounting hole 331, thereby further improving the sealing effect.

[0058] like Figure 6 As shown, in one specific embodiment, the infrared detection mechanism 4 includes an infrared sensor 42 and a third mounting base 43. The third mounting base 43 includes a base body 431 and a mounting plate 432. A sealed cavity is formed within the base body 431, and the infrared sensor 42 is disposed within the sealed cavity via the mounting plate 432. The base body 431 is located at the third opening 130 and is sealed to the third opening 130. The third sealing element 41 includes a sealing ring 411, which is sandwiched between the mounting plate 432 and the cavity wall of the sealed cavity.

[0059] The third mounting base 43 is disposed within the mounting chamber and corresponds to the third opening 130. Specifically, the third mounting base 43 can be fitted onto the third opening 130 to install the ultrasonic detection mechanism 3. Furthermore, the sealing fit between the third mounting base 43 and the third opening 130 can be achieved by an interference fit, ensuring a tight seal at the contact points and preventing water from the pool from flowing into the mounting chamber between the third mounting base 43 and the third opening 130.

[0060] Based on this, the sealing ring 411 is sandwiched between the mounting plate 432 and the cavity wall of the sealing cavity, which can also seal the infrared sensor 42. In this way, water in the pool will not enter the infrared sensor 42, thereby further ensuring the sealing effect of the infrared detection mechanism 4 itself, and thus further ensuring the normal use of the infrared detection mechanism 4.

[0061] like Figure 6As shown, furthermore, a third annular sealing groove is provided on the outer periphery of the mounting plate 432. A portion of the sealing ring 411 is located within the third annular sealing groove, and the other portion of the sealing ring 411 extends out of the third annular sealing groove and is press-fitted with the cavity wall of the sealing cavity. In this way, the sealing ring 411 can be squeezed between the third annular sealing groove and the cavity wall of the sealing cavity, thereby sealing the gap between the two by generating a certain degree of deformation, achieving a better sealing effect.

[0062] As shown in the figure, the sealing cavity is further divided into a first chamber 44 and a second chamber 45 by the mounting plate 432. The infrared sensor 42 is located in the first chamber 44, and the second chamber 45 is filled with sealant 412. This arrangement can achieve a complete seal of the first chamber 44, thereby further ensuring the sealing effect.

[0063] like Figure 7 As shown, in some embodiments, the pool cleaning machine also includes a control mechanism 6, which is disposed inside the mounting cavity of the housing 1.

[0064] The control mechanism 6 of the pool cleaner is used to implement and control various functions of the pool cleaner, ensuring its normal operation. For example, the control mechanism 6 is used to plan the movement path of the pool cleaner and to achieve obstacle avoidance, detour, or turning through the ultrasonic detection mechanism 3 or the infrared detection mechanism 4. It is also used to control the speed or intensity of the cleaning brush. It can even realize user interaction functions, such as Wi-Fi / Bluetooth control and uploading cleaning data.

[0065] Furthermore, the control mechanism 6 includes a chip 61, and a portion of the surface of the housing 1 is recessed toward the chip 61 to form a recessed groove 111, and the bottom of the recessed groove 111 is disposed opposite to the surface of the chip 61.

[0066] This design allows water from the pool to flow into the recessed groove 111. Since the recessed groove 111 is recessed towards the chip 61 and the bottom of the groove is opposite to the surface of the chip 61, the water in the recessed groove 111 can get closer to the chip 61, making it easier for the heat on the chip 61 to exchange heat with the water, thereby achieving rapid cooling and heat dissipation.

[0067] Please continue reading Figure 7 As shown, the housing 1 further includes a first housing 112 and a second housing 113, wherein a mounting opening is formed on the first housing 112, and the second housing 113 is covered at the mounting opening to define a mounting chamber together with the first housing 112. A recessed groove 111 is formed on the second housing 113, and the thickness of the second housing 113 is less than the thickness of the first housing 112.

[0068] In other words, the housing 1 can be composed of two parts: a first housing 112 and a second housing 113. The mounting port on the first housing 112 is used to place various mechanisms into the mounting chamber for assembly and fixation. A recessed groove 111 is formed on the second housing 113, so that the chip 61 is located at the corresponding mounting port position within the mounting chamber. Furthermore, the thickness of the second housing 113 is set to be less than the thickness of the first housing 112. The lower temperature of water on the second housing 113 side is more easily transferred to the mounting chamber compared to the first housing 112 position. Thus, the chip 61 positioned corresponding to the recessed groove 111 can better dissipate heat through water cooling.

[0069] To ensure the sealing of the installation chamber, a sealing element can be provided between the second housing 113 and the first housing 112 to achieve sealing at the installation port, such as by sandwiching a sealing gasket between the mounting plate 432112 and the housing.

[0070] In specific implementation, the recessed groove 111 can be configured in shape. The cross-section of the recessed groove 111 can be semi-circular, rectangular or trapezoidal. In this embodiment, the cross-section of the recessed groove 111 is set as trapezoidal. Specifically, the bottom of the recessed groove 111 is narrower and the opening is wider, so that water can be more easily poured into the recessed groove 111, thereby achieving rapid cooling and heat dissipation of the chip 61.

[0071] like Figure 8 and Figure 9 As shown, in some embodiments, the pool cleaning machine is also provided with a charging mechanism 77. The charging mechanism 77 is used to power on the pool cleaning machine, that is, to electrically connect the pool cleaning machine to an external power source so that the pool cleaning machine can work in a powered state.

[0072] A charging port 140 is provided on the housing 1. The charging port 140 is connected to the mounting chamber inside the housing 1 and is electrically connected to the power management module or main control module of the pool cleaning machine. The charging mechanism 77 includes a charging plug 71, which is disposed on the housing 1 and extends into the charging port 140 to facilitate electrical connection with an external charging cable.

[0073] Furthermore, the charging mechanism 77 also includes a protective cover 72, which is snapped onto the charging port 140 so that the charging port is located within a sealed cavity formed by the protective cover 72 and the housing 1. In addition, an abutment 721 is provided on the wall of the sealed cavity, which can be interference-fitted with the charging plug 71 along the circumference of the charging plug 71.

[0074] The protective cover 72 and the charging plug 71 are interference-fitted by the abutment member 721. In other words, the protective cover 72 and the charging plug 71 can fit tightly along the circumference of the charging plug 71. This not only ensures the sealing of the charging plug 71, but also eliminates the need for screws and other connecting parts compared to the traditional method of sealing the charging port by bolting the protective cover 72 to the housing 1. This saves the space occupied by the protective cover 72 and the charging plug 71 and reduces the complexity of installation.

[0075] like Figure 9 As shown, in one specific embodiment, the charging mechanism 77 further includes a connecting rope 73, one end of which is connected to the housing 1 and the other end to the protective cover 72. By providing the connecting rope 73, the protective cover 72 can be kept connected to the housing 1 after it is opened, thereby preventing the protective cover 72 from being lost.

[0076] Please continue reading Figure 9 As shown, the housing 1 further has a connection hole 150, the connection rope 73 is inserted through the connection hole 150, and one end of the connection rope 73 is provided with a blocking part, which is located inside the housing 1 and can abut against the inner edge of the connection hole 150.

[0077] In other words, the connecting rope 73 can slide and pull at the connecting hole 150, so that when the protective cover 72 is fastened to the charging port 140, the connecting rope 73 can be stored inside the housing 1. This reduces the number of connecting ropes 73 outside the housing 1, thus achieving a neat and aesthetically pleasing effect.

[0078] Based on this, a blocking part is provided at one end of the connecting rope 73, and the blocking part is located inside the housing 1 and abuts against the inner edge of the connecting hole 150. In this way, the connecting rope 73 will not come out of the connecting hole 150 due to the setting of the blocking part, thus ensuring the connection effect between the connecting rope 73 and the housing 1.

[0079] It should be noted that the connecting rope 73 can be made of elastic nylon rope or silicone rope with good corrosion resistance. In addition, the connecting rope 73 and the connecting hole 150 are also interference fit to ensure the sealing of the connecting hole 150.

[0080] Please continue reading Figure 9 As shown, the protective cover 72 is further provided with a gripping portion 722, thereby providing an operator with a point of gripping force when fastening or removing the protective cover 72. For example, the gripping portion 722 may include a connecting post and a gripping head, the gripping head being connected to the surface of the protective cover 72 via a thinner connecting post. Furthermore, the gripping head may be located at the top of the protective cover 72.

[0081] Based on this, a slotted hole can be provided at the other end of the connecting rope 73, and the gripping part 722 can be slidably connected to one end of the connecting rope 73 through the slotted hole. For example, the connecting post can be inserted into the slotted hole, which not only makes the sliding between the connecting rope 73 and the gripping part 722 more convenient, but also allows the connecting rope 73 to be fixed by the gripping head.

[0082] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
