In this embodiment, the cleaning device is, for example, a floor washer. In some other embodiments, the cleaning device may also be a vacuum cleaner or a multi-functional cleaning device.

[0031] As Figure 1 shown, the cleaning device of this embodiment includes a body housing 100, a battery pack 200, a main control board 300, and a seal 400. The body housing 100 includes a first cover 110 and a second cover 120. The second cover 120 and the first cover 110 jointly enclose a device accommodation cavity 130 located inside the body housing 100. The battery pack 200 and the main control board 300 are located inside the device accommodation cavity 130 and are electrically connected to each other inside the device accommodation cavity 130. The seal 400 is disposed at least along the boundary of the device accommodation cavity 130 and is clamped between the second cover 120 and the first cover 110.

[0032] A cleaning device according to an embodiment of the present utility model includes a body housing 100, a battery pack 200, a main control board 300, and a seal 400. The body housing 100 includes a first cover 110 and a second cover 120. The second cover 120 and the first cover 110 jointly enclose a device accommodation cavity 130 located inside the body housing 100. The battery pack 200 and the main control board 300 are located inside the device accommodation cavity 130 and are electrically connected to each other inside the device accommodation cavity 130. Therefore, there is no need to separately seal the battery pack 200 and the main control board 300, so that the battery pack 200 and the main control board 300 are hidden inside the device accommodation cavity 130. When the battery pack 200 and the main control board 300 are adjacent and located inside the device accommodation cavity 130, there is enough space to place battery packs 200 of various specifications, ensuring the sealing performance, with a simple structure, and can save the cost of the device, improve the use safety of the cleaning device and extend its service life. The seal 400 is disposed at least along the boundary of the device accommodation cavity 130 and is clamped between the second cover 120 and the first cover 110. By providing the seal 400, the normal use of the battery pack 200 and the main control board 300 in the normal working state can be ensured, and water flow or moisture can be prevented from entering the battery pack 200 and the main control board 300 in a humid environment, ensuring the reliability of the seal. By providing the device accommodation cavity 130 and the seal, double protection of the battery pack 200 and the main control board 300 can be achieved, improving the sealing performance while saving the cost of the device. The overall cleaning device is simple to operate and convenient to use, and is beneficial to good safety and protection.

[0033] Such as Figures 2 to 4As shown, in some embodiments, one of the first cover 110 and the second cover 120 is provided with a first partition wall 111 extending as a closed pattern, and the other is provided with a second partition wall 121 whose extending shape matches that of the first partition wall 111. The first partition wall 111 is provided with a limiting groove 1111, and the second partition wall 121 is inserted into the limiting groove 1111, so that the second cover 120 and the first cover 110 jointly enclose a device accommodating cavity 130. In this embodiment, the shapes of the first partition wall 111 and the second partition wall 121 are adapted to each other. The first partition wall 111 and the second partition wall 121 are closed patterns extending. The closed pattern can be a rectangle or a square, as long as it can ensure the adapted installation of the first partition wall 111 and the second partition wall 121, so as to improve the sealing performance of the device accommodating cavity 130. In the related art, when the cleaning device is in a humid environment, it is usually inevitable that water flow or moisture enters the device accommodating cavity 130, resulting in the abnormal operation and use of the cleaning device. By providing the first cover 110 and the second cover 120, the second cover 120 can enclose with the first cover 110 to form the device accommodating cavity 130, which can ensure that the battery pack 200 and the main control board 300 are both located in the device accommodating cavity 130, thereby preventing water flow from entering the device accommodating cavity 130 and affecting the normal use of the battery pack 200 and the main control board 300, and ensuring the normal use of the cleaning device.

[0034] In this embodiment, the first partition wall 111 is arranged on the first cover 110, and the second partition wall 121 is arranged on the second cover 120. After the second cover 120 and the first cover 110 are connected to each other, they enclose the device accommodating cavity 130. In some other embodiments, it can also be that the first partition wall 111 is arranged on the second cover 120, the second partition wall 121 is arranged on the first cover 110, and after the second cover 120 and the first cover 110 are connected to each other, they enclose the device accommodating cavity 130. By providing the limiting groove 1111, the first partition wall 111 and the second partition wall 121 can be tightly buckled, ensuring that the second partition wall 121 can be inserted into the limiting groove 1111, making the installation convenient and achieving the purpose of sealing and waterproofing at the same time.

[0035] Such as Figure 5As shown, in some embodiments, the seal 400 includes a sealing ring that extends around the boundary of the device receiving cavity 130. The sealing ring is installed in the limiting groove 1111. In this embodiment, the sealing ring is detachably installed in the limiting groove 1111. The sealing ring is an O-ring, and the material of the sealing ring is rubber, so it is ensured that it can closely fit in the limiting groove 1111. The first partition wall 111, the sealing ring, and the second partition wall 121 are adapted in shape, so that when the first partition wall 111 and the second partition wall 121 are matched, the sealing ring will not be deformed, thus preventing the sealing effect from being unstable and affecting the normal use of the cleaning device. The sealing ring is arranged around the limiting groove 1111. Since the sealing ring has great ductility, it can more appropriately match the limiting groove. In addition, the four sides of the limiting groove 1111 are arranged with arc transitions, which can ensure complete sealing performance. The limiting groove 1111 is arranged around the device receiving cavity 130. When the sealing ring is installed in the limiting groove 1111, it can ensure that the battery pack 200 and the main control board 300 are both located in the device receiving cavity 130, and there is no need to separately seal the battery pack 200 and the main control board 300, reducing the equipment cost, ensuring the reliability of the seal, and preventing water flow or moisture from entering the device receiving cavity 130 and affecting the normal use effect of the cleaning device.

[0036] In the above embodiment, the seal 400 can be a sealing ring, but it is not limited to a sealing ring. It can also be a sealing gasket or a packing seal, as long as the sealing performance can be ensured.

[0037] In some embodiments, the seal 400 includes a sheet-shaped seal that covers the second partition wall 121 and is clamped between the second cover 120 and the first cover 110. By providing the sheet-shaped seal, the sheet-shaped seal can completely cover the second partition wall 121 to play a role in sealing connection. When the first cover 110 and the second cover 120 are buckled, it can prevent water flow or dust from entering the device receiving cavity 130.

[0038] In the above embodiment, the sheet-shaped seal can be a seal sheet made of EVA (ethylene-vinyl acetate copolymer) material, or a seal sheet made of other sealing foam materials, or a seal sticker.

[0039] In some embodiments, the sheet-shaped seal is adhesively bonded to the second partition wall 121. The shape of the sheet-shaped seal is fully adapted to the second partition wall 121. The shape of the sheet-shaped seal is rectangular, and the four sides are in an arc transition. Since the sheet-shaped seal has a large flatness, when the sheet-shaped seal is installed on the second partition wall 121, it can ensure that the four sides of the sheet-shaped seal can completely cover the second partition wall 121, and when the second partition wall 121 and the first partition wall 111 are matched, the battery pack 200 and the main control board 300 will not be worn, which is beneficial to a good sealing effect, and the sealing performance can be made more reliable by the adhesive bonding method.

[0040] In some embodiments, the sheet-shaped seal is adhesively bonded to the second partition wall 121 by providing an adhesive layer on the surface. In some other embodiments, other adhesive members can also be added to achieve the adhesive bonding of the sheet-shaped seal and the second partition wall 121.

[0041] In some embodiments, at least one of the first partition wall 111 and the second partition wall 121 is provided with a wire opening 1112. The battery pack 200 and / or the main control board 300 are electrically connected to components outside the device accommodation cavity 130 through wires (not shown in the figure), and the wires are passed through the wire opening 1112. By providing the wires, the battery pack 200 and / or the main control board 300 can be electrically connected to components outside the device accommodation cavity 130. Among them, the external components can be a control panel. By electrically connecting the battery pack 200 and / or the main control board 300 and the external components, it can be used to supply power and control the device. The control panel is signal-connected through the battery pack 200 to control the machine and ensure the normal operation of the cleaning device.

[0042] In the above embodiments, the wire opening 1112 is provided in the first partition wall 111. When the battery pack 200 and / or the main control board 300 are electrically connected to components outside the device accommodation cavity 130 through wires, the operation of the cleaning device can be realized. A plurality of shielding columns are respectively provided on the sides of the first partition wall 111 and the second partition wall 121. The shielding columns are provided on both sides of the wire opening 1112. The shielding columns can be provided on the bottom surface of the wire opening 1112 or on the top surface of the wire opening 1112, as long as they can play a protective role. In addition, the wire opening 1112 can also be provided in the second partition wall 121 to ensure that the wire can pass through the wire opening 1112 and is located on the side boundary of the device accommodation cavity 130.

[0043] In some embodiments, when the cleaning device is in a working state, the boundary of the device accommodating cavity 130 includes a side boundary erected relative to the ground, and the wire opening 1112 is located on the side boundary. In this embodiment, the device accommodating cavity 130 has two oppositely arranged side boundaries, and the wire opening 1112 can be provided on both of the two side boundaries. In some embodiments, the wire opening 1112 is located in a region of the side boundary near the top. When the wire opening 1112 is located on the side boundary, liquids such as water flow will not directly flow into the device accommodating cavity 130 where the battery pack 200 and the main control board 300 are located along the wire, thus preventing problems such as short circuits from occurring and ensuring the overall safety performance of the cleaning device. In the above embodiment, the wire opening 1112 is located in a region of the side boundary near the top. In some other embodiments, the wire opening 1112 can also be located in the middle region or the region near the bottom of the side boundary, as long as it can ensure that the battery pack 200 and / or the main control board 300 are electrically connected to components outside the device accommodating cavity 130 through the wire and water flow will not enter the device accommodating cavity 130 through the wire opening 1112.

[0044] In the above embodiment, the number of the wire openings 1112 is two. In some other embodiments, the number of the wire openings 1112 is not limited to two, and can also be other numbers such as four or five, which are set according to the electrical connection requirements.

[0045] In some embodiments, a sealant (not shown in the figure) is filled between the wall surface of the wire opening 1112 and the wire. In this embodiment, in order to ensure the waterproof performance, the sealant usually has high flexibility and can adapt to a certain deformation. When the sealant is filled between the wall surface of the wire opening 1112 and the wire, the sealing performance of the connection can be ensured, so that the wire can be tightly attached to the wire opening 1112 without moving randomly, thus affecting the reliability of the wire function, and can effectively prevent water flow or water vapor from entering the device accommodating cavity 130 where the battery pack 200 and the main control board 300 are located, preventing damage to the components caused by a humid environment.

[0046] Optionally, the sealant can be a deformable prefabricated part. After the second cover 120 and the first cover 110 are combined and connected, the sealant is clamped in the wire opening 1112, and the sealant is in sealing contact with the wire.

[0047] In some embodiments, the first cover 110 has a first installation area 131 and a second installation area 132 that are adjacent to each other within the device accommodation cavity 130. The main control board 300 is installed in the first installation area 131, and the battery pack 200 is installed in the second installation area 132. In this embodiment, the battery pack 200 is detachably arranged in the second installation area 132. To facilitate the accurate insertion of the battery pack 200 into the second installation area 132, it is necessary to ensure that the interface of the battery pack 200 is docked with the interface at the bottom of the second installation area 132. A guiding groove can be provided on the side wall of the battery pack 200, and an insertion protrusion adapted to the guiding groove is provided on the inner wall of the second installation area 132 to ensure the accurate placement position of the battery pack 200. In addition, the battery pack 200 is arranged in the second installation area 132, and the second installation area 132 is located below the overall cleaning device. Therefore, by setting the position of the battery pack 200, when it is installed below the cleaning device, the overall center of gravity of the cleaning device can be unchanged, which is more convenient to use and easier to operate during the operation of the cleaning device. The main control board 300 and the battery pack 200 are adjacent to each other within the device accommodation cavity 130, and the main control board 300 is attached to the first installation area 131, facilitating the stable installation of the main control board 300 and the battery pack 200 in the first installation area 131 and the second installation area 132 after the second cover 120 and the first cover 110 are jointly enclosed. In addition, multiple groups of battery packs 200 can be provided. The multiple groups of battery packs 200 are jointly installed in the device accommodation cavity 130. There is no need to separately seal each group of battery packs 200. When the cleaning device is working, when charging, repairing, or replacing another battery pack 200, the battery pack 200 with depleted power can be replaced in time, which will not affect the overall use effect of the cleaning device, can effectively extend the working time of the cleaning device, and there is no need to disassemble the whole cleaning device.

[0048] In some embodiments, the first installation area 131 is provided with positioning posts and through holes. The main control board can be installed on the positioning posts through the through holes, so that the main control board 300 can be closely attached to the first installation area 131 and will not move randomly. The first installation area 131 is also provided with protective posts, and the protective posts are arranged diagonally in the first installation area 131. Among them, the number of protective posts is set to 2, but it is not limited to 2, and can also be 3 or 4. Through the setting of the positioning posts and the protective posts, the main control board 300 can be stably installed on the first installation area 131 and is not damaged.

[0049] In some embodiments, the second cover 120 is detachably connected to the first cover 110. In some embodiments, the body housing 100 may include a front body cover and a rear body cover. In this embodiment, the first cover 110 is the rear body cover and the second cover 120 is the front body cover. In some other embodiments, it may also be that the first cover 110 is the front body cover and the second cover 120 is the rear body cover. When it is necessary to disassemble the battery pack 200 and the main control board 300, separating the second cover 120 from the first cover 110 can disassemble the battery pack 200 and the main control board 300 without affecting the integrity of the cleaning device. In the way of detachable connection, it is beneficial to facilitate the maintenance operation of the cleaning device and the connection is more reliable.

[0050] In the above embodiment, the connection mode between the second cover 120 and the first cover 110 is snap connection. A plurality of clamping blocks are arranged around the side of the first cover 110. A plurality of clamping grooves can be arranged on the side of the first cover 110, and clamping blocks adapted to the clamping grooves are arranged on the side of the second cover 120, so that the first cover 110 and the second cover 120 can be abutted against each other to ensure the stability of the connection. However, the connection mode is not limited to snap connection, and it can also be connected by screw connection or magnetic attraction connection.

[0051] According to the cleaning device of the embodiment of the present invention, the second cover 120 and the first cover 110 jointly enclose a device accommodation cavity 130 located inside the body housing 100, and the battery pack 200 and the main control board 300 are both located inside the device accommodation cavity 130. Therefore, the battery pack 200 and the main control board 300 are directly electrically connected to each other inside the device accommodation cavity 130. On the one hand, there is no need to separately provide a sealing structure for the battery pack 200 and the main control board 300, and a more stable sealing of the battery pack 200 and the main control board 300 is achieved with a simplified structure. On the other hand, the electrical connection structure between the battery pack 200 and the main control board 300 is also inside the device accommodation cavity 130, so there is no need to provide a complex sealing structure for the electrical connection structure between the battery pack 200 and the main control board 300, reducing the setting cost of the sealing structure of the cleaning device.

[0052] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
