[0025] 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.

[0026] Firstly, please refer to Figure 1 and Figure 2This application provides a sealing box 100 for a swimming pool cleaning device. The sealing box 100 includes a main housing 10 and at least one compensation housing 20. At least one electronic component is disposed inside the main housing 10. At least one opening 101 is provided on the peripheral side of the main housing 10. The aperture size of the opening 101 is r1. The width dimension of the main housing 10 is h. r1 and h satisfy: r1≤0.7h. A compensation housing 20 is disposed at one opening 101, and the compensation housing 20 is sealed to the main housing 10 to form a sealed space.

[0027] Optionally, the main housing 10 can be shaped like a cuboid. The main housing 10 has an internal cavity. At least one opening 101 is provided on the peripheral side of the main housing 10. The opening 101 communicates with the cavity. The electronic components can be small devices such as sensors and control chips. The electronic components can be installed in the cavity through the opening 101, and thus the electronic components can be conveniently installed in various positions inside the main housing 10.

[0028] The number of compensation housings 20 can be the same as the number of openings 101, and one compensation housing 20 can correspond to one opening 101. That is, the outer contour shape of the compensation housing 20 is adapted to the shape of the opening 101, and the outer contour size of the compensation housing 20 is the same as the aperture size of the opening 101. When the compensation housing 20 is set at the corresponding opening 101, the compensation housing 20 can be sealed with the main housing 10 to form a sealed space, which can prevent water from seeping into the main housing 10 from the opening 101.

[0029] In this embodiment, the aperture size r1 of the opening 101 and the width dimension h of the main housing 10 satisfy r1≤0.7h. When the opening 101 is opened on the peripheral side of the main housing 10, the opening 101 will only occupy a part of the area of ​​the peripheral side of the main housing 10. The main housing 10 has enough shell wall surface to form a sealing fit with the compensation housing 20, which increases the sealing performance between the main housing 10 and the compensation housing 20 and ensures that water will not penetrate into the main housing 10 from the opening 101.

[0030] It should be noted that the end face of the main housing 10 may be provided with a port, and the sealing box 100 may also include a box cover. The box cover is provided on the port to seal the main housing 10. The extension direction of the port axis is in the same direction as the length direction of the sealing box 100. Long electronic components such as circuit boards can be inserted into the receiving cavity from the port, which facilitates the installation of the circuit board in the main housing 10.

[0031] In some embodiments, the shape and size of the port can be the same as the shape and size of an opening 101, so that the lid can form a sealing fit with the opening 101, and a compensation housing 20 can form a sealing fit with the port, thereby the compensation housing 20 can also be used as a lid.

[0032] Please see Figure 1 and Figure 2 In some embodiments, the main housing 10 has a length dimension of D, and r1 and D satisfy: r1 < 0.5D.

[0033] Optionally, the main housing 10 has a length dimension of D, r1 < 0.5D, so that multiple openings 101 can be opened on the main housing 10, for example, three openings 101 can be opened on the peripheral side of the main housing 10, and the three openings 101 can be arranged along the length direction, so that electronic components can be conveniently installed in various positions inside the main housing 10.

[0034] Please see Figure 1 and Figure 2 In some embodiments, the main housing 10 further includes at least one secondary opening 102, which communicates with the opening 101, and the aperture size of the secondary opening 102 is r2, where r2 and D satisfy: r2≤0.3D.

[0035] Optionally, when r1, r2 and D satisfy: r2 < r1, r2 ≤ 0.3D, it can be ensured that the secondary opening 102 is set inside the opening 101, and the peripheral side of the main housing 10 has enough space to set multiple openings 101 and multiple secondary openings 102.

[0036] Both the secondary opening 102 and the opening 101 are circular in shape. The secondary opening 102 and the opening 101 are interconnected and coaxially arranged. The aperture size r2 of the secondary opening 102 is smaller than the aperture size r1 of the opening 101, so that the secondary opening 102 is located inside the opening 101. A first step can be formed between the secondary opening 102 and the opening 101. The compensation housing 20 can have a second step. When the compensation housing 20 is set at the opening 101, the second step can engage with the first step, that is, the step surface of the second step abuts against the step surface of the first step and forms a seal, which can increase the sealing contact area between the compensation housing 20 and the main housing 10, and further increase the sealing performance between the main housing 10 and the compensation housing 20.

[0037] Please see Figure 1 and Figure 2In some embodiments, the main housing 10 is provided with a sealing surface 103, which extends around the axis of the opening 101. The compensation housing 20 is disposed at the opening 101 and is sealed to the sealing surface 103. The edge of the sealing surface 103 is a continuous smooth curve.

[0038] Optionally, the sealing surface 103 is an annular curved surface, and the sealing surface 103 extends around the axis of the opening 101. The compensation housing 20 has a mating surface, which is also an annular curved surface. When the compensation housing 20 is located at the opening 101, the sealing surface 103 can be adapted to the mating surface, so that the compensation housing 20 and the sealing surface 103 are sealed together, further increasing the sealing performance of the main housing 10 and the compensation housing 20.

[0039] In some embodiments, the sealing surface 103 intersects with the first plane to form an intersection line, which is a continuous smooth curve. The first plane is perpendicular to the axis of the opening 101, so that the sealing surface 103 and the compensation housing 20 can fit more tightly, further increasing the sealing performance of the main housing 10 and the compensation housing 20.

[0040] In some embodiments, the shape enclosed by the smooth curve is elliptical or circular.

[0041] Optionally, the smooth curve can form an annular shape, and the shape formed by the smooth curve is elliptical or circular, so that the opening 101 enclosed by the sealing surface 103 is an elliptical hole or a circular hole, which makes it convenient to cover the compensation housing 20 at the opening 101.

[0042] In some embodiments, the sealing surface 103 and the compensation housing 20 are sealed by a sealing ring.

[0043] Optionally, when the compensation housing 20 is closed at the opening 101, an annular mounting groove can be formed between the compensation housing 20 and the sealing surface 103. The sealing ring is disposed in the annular mounting groove, thereby filling the gap between the sealing surface 103 and the compensation housing 20, forming a sealing structure between the sealing surface 103 and the compensation housing 20, preventing water from entering the main housing 10 from between the sealing surface 103 and the compensation housing 20.

[0044] In some embodiments, the sealing ring is an O-ring with a circular cross-section. The O-ring has a simple structure, low cost, and convenient installation. When the sealing ring is placed between the compensation housing 20 and the sealing surface 103, the compensation housing 20 compresses the sealing ring, causing the sealing ring to undergo elastic deformation in the radial and axial directions, and filling the gap between the compensation housing 20 and the sealing surface 103 to form a waterproof barrier to prevent water from entering the interior of the main housing 10.

[0045] Please see Figure 1 and Figure 2In some embodiments, the main housing 10 is also provided with an electrical connection port, and at least one opening 101 is disposed opposite to the electrical connection port.

[0046] Optionally, the electrical connection port is located inside the main housing 10, and the position of the electrical connection port inside the main housing 10 is opposite to at least one opening 101, so that the electrical connection port can be extended into the main housing 10 from the opening 101 and installed on the main housing 10.

[0047] In this embodiment, the electrical connection port is also provided facing the opening 101. The electrical connection port can be accessed through the opening 101 to facilitate plugging and unplugging operations. For example, the connecting wire can be inserted into the main housing 10 through the opening 101 and plugged into the electrical connection port. Alternatively, the connecting wire can be unplugged from the electrical connection port and taken out through the opening 101.

[0048] Please see Figure 1 and Figure 2 In some embodiments, the compensation housing 20 is provided with a mounting hole 201, and a connecting wire is passed through the mounting hole 201. The connecting wire is detachably connected to the electrical connection port.

[0049] Optionally, when installing the connecting wire, firstly, the first end of the connecting wire is inserted into the main housing 10 through the opening 101, and then the first end of the connecting wire is inserted into the electrical connection port. Next, the connecting wire is passed through the mounting hole 201 of the compensation housing 20. Finally, the compensation housing 20 is closed at the opening 101. The mounting hole 201 allows the connecting wire to pass through, preventing interference between the compensation housing 20 and the connecting wire.

[0050] In some embodiments, a sealing ring is provided between the mounting hole 201 and the connecting wire. The sealing ring can seal the gap between the connecting wire and the hole wall of the mounting hole 201, further increasing the sealing performance of the main housing 10.

[0051] In some embodiments, at least one sensor is also provided inside the main housing 10, and the sensor can be installed inside the main housing 10 through the opening 101.

[0052] Optionally, the main housing 10 is provided with multiple sensors, and the installation position of each sensor corresponds to an opening 101. When installing the sensor, the sensor can be inserted into the main housing 10 through the opening 101 and directly installed at the target position, which makes it very convenient to install the sensor.

[0053] In some embodiments, the sensor is one of a camera sensor, an infrared sensor, an ultrasonic sensor, and a pressure sensor.

[0054] Understandably, when the sensor is a camera sensor, it can identify static obstacles such as pool walls, drains, ladders, and pool bottom stains, as well as dynamic floating objects such as leaves and branches. Combined with SLAM (Simultaneous Localization and Mapping) algorithm, it can achieve autonomous navigation and assist in cleaning up trash in the pool.

[0055] When the sensor is an infrared sensor, it can detect obstacles within a short range (10cm-200cm) and trigger emergency braking or path adjustment to help the pool cleaning equipment avoid obstacles.

[0056] When the sensor is an ultrasonic sensor, it can detect obstacles within a range of 0.2-5m in front of the pool cleaning equipment, thereby improving the obstacle avoidance capability of the pool cleaning equipment.

[0057] When the sensor is a pressure sensor, it can calculate the immersion depth of the pool cleaning equipment or the water level of the pool by measuring the water pressure.

[0058] In some embodiments, at least one sensor is provided within the compensation housing 20, and the sensor is accessible through the opening 101 for installation operations.

[0059] Optionally, the compensation housing 20 may also have a position for installing a sensor. When installing the sensor, the sensor can be installed on the compensation housing 20 first, and then the compensation housing 20 can be closed to the opening 101. The sensor can be inserted into the main housing 10 through the opening 101, which makes it very convenient to install the sensor.

[0060] In some embodiments, the sealing box 100 includes at least two main housings 10, each main housing 10 having a connecting post 104 located around the opening 101. Two adjacent main housings 10 are connected by the connecting post 104, and the opening 101 is sealed. A connecting wire passes through the opening 101.

[0061] Taking the sealed box 100, which includes two main housings 10, as an example, for ease of description, one of the two main housings 10 is defined as the first main housing, the opening 101 on the first main housing is defined as the first opening, the connecting post 104 on the first main housing is defined as the first connecting post, and the other of the two main housings 10 is defined as the second main housing, the opening 101 on the second main housing is defined as the second opening, and the connecting post 104 on the second main housing is defined as the second connecting post.

[0062] Specifically, the first main housing is provided with a plurality of first connecting posts, which are located around the periphery of the first opening and are arranged at intervals along the circumference of the first opening. Each first connecting post is provided with a first connecting hole, the axis of which is the same as the axis of the first opening. The second main housing is provided with a plurality of second connecting posts, which are located around the periphery of the second opening and are arranged at intervals along the circumference of the second opening. Each second connecting post is provided with a second connecting hole, the axis of which is the same as the axis of the second opening.

[0063] The sealing box 100 also includes multiple connectors, which can be sequentially inserted into the first connecting hole and the second connecting hole to connect the first main housing and the second main housing together, and align the first opening with the second opening so that the wall surface of the first opening abuts against the wall surface of the second opening to form a sealing contact. Alternatively, a sealing ring can be provided between the wall surface of the first opening and the wall surface of the second opening to seal the gap between the first opening and the second opening.

[0064] In some embodiments, a first sensor is provided inside the first main housing, and a second sensor is provided inside the second main housing. The first sensor can be electrically connected to the second sensor via a connecting wire, which can pass through the first opening and the second opening for easy wiring.

[0065] Thus, when one of the main housings 10 in the sealing box 100 is damaged, only the damaged main housing 10 needs to be replaced, which makes it convenient to repair the sealing box 100. Furthermore, the main housing 10 in one sealing box 100 can be used as the main housing 10 in another sealing box 100, which increases the versatility of parts.

[0066] Secondly, this application embodiment also provides a swimming pool cleaning device, which includes a cleaning machine housing and a sealing box for swimming pool cleaning as described above. The sealing box is equipped with a sensor and is disposed inside the cleaning machine housing. The cleaning machine housing is at least partially transparent, and the sensor is disposed near the outer surface of the transparent housing. The sensor senses external environmental information through the transparent housing.

[0067] Optionally, the sensor can be a camera sensor. When the sensor is placed close to the outer surface of the transparent housing, the infrared sensor can sense external environmental information through the transparent housing, thereby detecting obstacles near the pool cleaning equipment. When the sensor detects an obstacle in the path of the pool cleaning equipment, it can trigger emergency braking or adjust the path of travel to help the pool cleaning equipment avoid the obstacle. The sealing box 100 is placed inside the cleaning machine housing and can protect the sealing box 100.

[0068] Thirdly, this application also provides a swimming pool cleaning device, which includes a cleaning machine housing and a sealing box for swimming pool cleaning as described above. The sealing box is provided with a sensor, and the cleaning machine housing is provided with an opening. The sensor is disposed inside the cleaning machine housing and exposed to the opening.

[0069] Optionally, the sensor can be a camera sensor or an infrared sensor. When the sensor is exposed to the opening, it can identify static obstacles such as pool walls, drains, ladders, and pool bottom stains, as well as dynamic floating objects such as leaves and branches, to assist in cleaning up trash in the pool. By setting an opening on the cleaning machine housing, interference with the sensor's detection of obstacles can be prevented.

[0070] Fourthly, this application embodiment also provides a swimming pool cleaning device, which includes a sealing box for swimming pool cleaning as described above, a sensor being provided on the sealing box, the sealing box being located on the outer surface of the swimming pool cleaning device, and the sensor being exposed on the outer surface of the swimming pool cleaning device.

[0071] Alternatively, the sensor can be a pressure sensor, with the sensor exposed on the outer surface of the pool cleaning equipment so that the sensor can be submerged in the pool water, making it convenient for the sensor to detect the water pressure in the pool.
