[0022] Please refer to Figures 1 to 9. This utility model provides a cleaning device 100 with a crevice cleaning function. The initial design purpose of this cleaning device 100 is to efficiently clean various types of pools, such as landscape pools, fish ponds, and especially swimming pools, which are frequently used and have high hygiene requirements. In these pools, the pool wall to be cleaned constitutes the surface to be cleaned. Due to construction processes such as tile splicing, gaps inevitably form on the pool wall. These gaps often become "hiding places" for dirt, and traditional cleaning methods are difficult to completely remove the dirt.

[0023] The cleaning device 100 mainly consists of a body 10, cleaning components, and a drive mechanism. The body 10 is equipped with the cleaning components and the drive mechanism. The drive mechanism drives the body 10 to move along a first direction on the surface to be cleaned, thereby causing the cleaning components to contact and clean the surface in a preset sequence. It can be understood that the first direction is approximately parallel to the surface to be cleaned and also approximately parallel to the first side of the body 10 facing the surface. When the cleaning device 100 is working, the first direction relative to the working environment can change according to the movement of the cleaning device 100. For the cleaning device 100 itself, the first direction is fixed and depends on the design of the drive mechanism. Taking this embodiment as an example, the drive mechanism includes a track that rotates around a pivot, and the first direction is approximately parallel to the pivot direction of the track.

[0024] The material and structure of cleaning tools can be meticulously designed based on the specific purpose of the pool and the material of the surface to be cleaned. For example, for landscape pools, considering the potential presence of various debris and dust, a durable nylon brush can be used. The nylon brush body is tough and effectively removes stubborn stains. For fish ponds, to avoid harming the fish and disrupting the pond's ecosystem, soft silicone cleaning tools can be used, which won't scratch the fish while achieving good cleaning results. For swimming pools, due to extremely high hygiene standards, antibacterial fiber cloths can be selected to inhibit bacterial growth while cleaning.

[0025] The cleaning component offers several installation options. It can be fixedly mounted to the main body 10, in which case the component uses the relative movement between the main body 10 and the surface to be cleaned to scrape and clean the surface. For example, the cleaning component can be designed as a scraper fixed to the bottom of the main body 10; as the main body 10 moves across the pool wall, the scraper continuously scrapes the surface to remove dirt. Alternatively, the cleaning component can be movably mounted to the main body 10 and driven by a drive mechanism to actively contact the surface to be cleaned. For example, a rotating roller brush mounted on the main body 10, driven by a motor, rotates at high speed, actively contacting the surface to be cleaned, enhancing cleaning power and effectiveness.

[0026] In this embodiment, please refer to Figures 1 to 6The cleaning components include a first cleaning component 20 and a second cleaning component 30. The body 10 has a first side 11 facing the surface to be cleaned; for example, the outer side of the bottom plate of the body 10 facing the surface to be cleaned constitutes this first side 11. The first cleaning component 20 is disposed on the body 10 and at least partially protrudes outward from the first side 11 relative to the body 10, and has a first cleaning portion 211 that contacts the surface to be cleaned during operation to perform a cleaning action. The second cleaning component 30 is disposed on at least one of the first cleaning component 20 and the body 10, and at least partially protrudes outward from the first side 11 relative to the body 10, and has a second cleaning portion 311 that contacts the surface to be cleaned during operation to perform a cleaning action. It is understood that through the structural design of the second cleaning component 30, multiple second cleaning portions 311 can be distributed.

[0027] The installation method of the first cleaning component 20 and the second cleaning component 30 is not limited. Generally, the first cleaning component 20 is detachably installed on the body 10. The second cleaning component 30 can be installed only on the first cleaning component 20, cleaning along with the cleaning action of the first cleaning component 20, simultaneously cleaning the surface to be cleaned and its crevices in the same area. Alternatively, the second cleaning component 30 can be installed only on the body 10, spaced apart from the first cleaning component 20, thus working in conjunction with the first cleaning component 20 to clean the surface to be cleaned and its crevices in the same area sequentially. Preferably, the second cleaning component 30 is installed on both the body 10 and the first cleaning component 20, so that the crevices of the surface to be cleaned in the same area are cleaned multiple times sequentially to enhance the cleaning effect.

[0028] Furthermore, the drive mechanism drives the cleaning device 100 to travel along a first direction, and the second direction is perpendicular to the first direction and parallel to the first side. In one embodiment, the size of the second cleaning part 311 in the second direction is smaller than that of the first cleaning part 211. Preferably, multiple second cleaning parts are provided and are spaced apart in the second direction. Preferably, the size of the second cleaning part 311 in the second direction is less than or equal to 2 mm. In this way, during the travel of the cleaning device 100, the smaller second cleaning part 311, due to its smaller size in the second direction, can reach into the tile grout, thereby sweeping out the dirt in the tile grout and achieving precise cleaning of the grout area.

[0029] In another preferred embodiment, the protrusion height of the second cleaning component 30 relative to the first side 11 is greater than that of the first cleaning component 20. It should be noted that the difference in protrusion height between the second cleaning component 30 and the first cleaning component 20 can be achieved either by different dimensions or by different installation methods. Specifically, the protrusion height refers to the maximum distance between the end of the cleaning component furthest from the first side 11 during the entire cleaning operation and the first side 11.

[0030] In this embodiment, during actual cleaning operations, the first cleaning component 20 can perform routine cleaning on large areas such as the pool wall, while the second cleaning component 30, with its larger protrusion height compared to the first cleaning component 20, can penetrate deep into the tile grout to effectively remove the dirt. This allows the cleaning device 100 to perform routine cleaning of the pool wall while simultaneously cleaning the tile grout on the pool wall, greatly improving the cleaning effect and effectively reducing the time and labor costs required for users to maintain the pool.

[0031] It is understood that the two implementation methods described above can be implemented separately or together.

[0032] Based on the previous embodiment, the second cleaning component 30 includes a plurality of second cleaning bodies 31, which are arranged in a dispersed manner. Specifically, as shown in the figure... Figure 8 and Figure 9 As shown, the second cleaning component 30 may further include a mounting portion 32. One end of each of the plurality of second cleaning bodies 31 is fixed to the mounting portion 32 and connected and fixed to the body 10 or the first cleaning body 21 through the mounting portion 32. The other ends of the plurality of second cleaning bodies 31 are dispersed from each other to form a second cleaning section for penetrating deep into the crevice area. It should be noted that in the accompanying drawings provided in this embodiment, the plurality of second cleaning bodies 31 are still shown as a whole.

[0033] In actual products, multiple second cleaning bodies 31 should be distributed separately. For example, the second cleaning component 30 includes a brush bundle, and the second cleaning body 31 is the bristles that make up the brush bundle. In this embodiment, multiple distributed second cleaning bodies 31 can contact the tile grout from different angles. Compared with a one-piece cleaning component, they can more comprehensively cover all corners of the grout, avoiding cleaning dead spots. Even in complex grout environments, the distributed second cleaning bodies 31 can flexibly enter and clean the grout, improving the cleaning effect and ensuring that dirt in the grout is effectively removed.

[0034] Specifically, in one embodiment, the second cleaning member 30 includes a brush bundle, and each second cleaning body 31 is a bristle that makes up the brush bundle. It is understood that, since dirt in crevices is relatively stubborn, the material rigidity of the second cleaning body 31 should generally be greater than that of the first cleaning body 21, where the first cleaning body 21 is the part of the first cleaning member 20 that contacts the surface to be cleaned. Preferably, the bristles can be made of nylon and have a long, thin shape, thereby allowing them to penetrate deep into crevices and clean them with stronger cleaning power. In this embodiment, the bristles are soft and elastic, enabling them to better conform to the shape of the crevices when penetrating them, and effectively remove dirt from the crevices through the oscillation and friction of the bristles.

[0035] Based on the above embodiments, in one embodiment, see [reference needed]. Figures 1 to 3The first cleaning component 20 is movably mounted on the body 10, and the second cleaning component 30 is disposed on the first cleaning component 20. In this embodiment, the movable installation method of the first cleaning component 20 can be diversified. In addition to rotational installation and sliding installation, a universal joint installation method can also be adopted, so that the first cleaning component 20 can rotate flexibly in multiple directions to better adapt to surfaces of different shapes to be cleaned.

[0036] In this embodiment, the first cleaning component 20 is movably installed, ensuring that the cleaning device 100 maintains good contact with the surface to be cleaned while moving in the pool. The first cleaning component 20 uses friction to remove dirt, reducing the moving resistance of the cleaning device 100 and improving the cleaning effect. The second cleaning component 30 is mounted on the first cleaning component 20, allowing for more flexible contact with crevices as the first cleaning component 20 moves. For example, when the first cleaning component 20 rotates for cleaning, the second cleaning component 30 also rotates accordingly, contacting the crevices at different angles, improving the flexibility and adaptability of the cleaning process and ensuring more thorough cleaning of the crevices.

[0037] Preferably, the first cleaning component 20 includes a rotating shaft 22 and a first cleaning body 21. The first cleaning component 20 is rotatably mounted on the machine body 10 via the rotating shaft 22, and the first cleaning body 21 is disposed on the outer periphery of the rotating shaft 22, preferably sleeved on the outer periphery of the rotating shaft 22. In this embodiment, as shown... Figure 2 and Figure 3 As shown, the first cleaning body 21 protrudes outward from the outer periphery of the rotation shaft 22 in the radial direction, and the second cleaning member 30 also extends outward from the outer periphery of the rotation shaft 22 and is fixed to the rotation shaft 22 or the first cleaning body 21. Preferably, the second cleaning member 30 extends from one end of the rotation shaft 22 in the axial direction to the other end, so as to cover as much of the surface area to be cleaned as possible where there may be gaps.

[0038] In this embodiment, the design of the rotating shaft 22 allows the first cleaning body 21 to rotate, enabling more efficient cleaning of large areas. The second cleaning component 30 is fixed to the rotating shaft 22 or the first cleaning body 21 and can rotate with it. During rotation, the second cleaning component 30 can contact the tile grout at different angles and positions, further improving the cleaning efficiency of the tile grout. At the same time, this arrangement ensures the stability of the second cleaning component 30 during the cleaning process, enabling it to continuously and effectively clean the dirt in the grout.

[0039] Preferably, the first cleaning body 21 and the second cleaning component 30 are integrally formed, and the first cleaning body 21 is detachably sleeved on the rotating shaft 22. In this way, the first cleaning body 21 and the second cleaning body 31 can be removed from the rotating shaft 22 as a whole for maintenance, replacement and cleaning, which facilitates the maintenance operation of the cleaning component.

[0040] Optionally, the second cleaning component 30 can be detachably installed on the first cleaning component 20. In this embodiment, the second cleaning component 30 can be selected in different specifications and installed on the first cleaning component 20 according to the actual distribution, depth, and degree of dirt in the gap, thereby achieving a more targeted and efficient cleaning effect. Its detachable installation method can be varied, such as snap-fit ​​connection, magnetic attraction, or Velcro adhesion. It can be understood that when the degree of dirt in the gap is not high, the second cleaning component 30 may not be installed, and only the first cleaning component 20 can be used to clean the surface to be cleaned, reducing resistance and improving cleaning efficiency.

[0041] Optionally, the second cleaning element 30 extends in a spiral shape around the pivot 22. In this embodiment, the spiral distribution of the second cleaning element 30 allows it to penetrate deep into the crevices during cleaning, generating a certain amount of pressure and friction, thus more effectively removing stubborn stains from the crevices. It also increases the likelihood of cleaning the same crevic multiple times, thereby achieving a better crevic cleaning effect.

[0042] Based on the above embodiments, in one embodiment, please refer to... Figure 1 The cleaning equipment 100 also includes a drive mechanism that drives the body 10 to travel in a first direction. Please continue reading. Figure 1 and Figure 4 The second cleaning component 30 is disposed on the body 10, and the body 10 also has a suction port 40. The second cleaning component 30 is distributed at least in front of or behind the suction port 40 in the first direction. In this embodiment, the suction port 40 is connected to the sludge storage bin on the body 10, and is used to promptly suck the dirt scraped off by the cleaning component into the sludge storage bin to prevent contamination of the water quality in the pool. The second cleaning component 30 is distributed near the suction port 40, which facilitates the flow of water to the vicinity of the suction port 40 during the movement of the cleaning device 100, so that dirt and impurities brought by the scraping gap of the second cleaning component 30 can be promptly sucked in.

[0043] Specifically, in a preferred embodiment, the second cleaning component 30 is at least distributed in front of the suction port 40 in the first direction. Thus, utilizing the water flow direction during the movement of the cleaning device 100, the dirt generated by the second cleaning component 30 is carried towards the vicinity of the suction port 40 and promptly sucked in. The second cleaning component 30 is distributed in front of the suction port 40 in the first direction and on both sides of the suction port 40 in the second direction. Thus, with the second cleaning component 30 distributed in front of and on both sides of the suction port 40, dirt around the suction port 40 can be cleaned from multiple directions. During the movement of the cleaning device 100, regardless of the direction from which dirt is cleaned, it can be promptly sucked away by the suction port 40, further improving the cleaning effect and dust collection efficiency, and reducing dirt residue.

[0044] Furthermore, such as Figure 4As shown, the second cleaning component 30 includes multiple second cleaning bodies 31, arranged in multiple groups. Each group of second cleaning bodies 31 extends obliquely outward from the center of the body 10 in a first direction, and the multiple groups of second cleaning bodies 31 are arranged linearly around the suction port 40. This arrangement creates multiple flow channels between the second cleaning bodies 31, guiding water flow through the gaps between the groups of cleaning bodies and reducing the resistance to movement caused by the second cleaning component 30. Furthermore, dirt can more easily flow to the suction port 40 through these flow channels.

[0045] Optionally, the second cleaning component 30 includes a mounting portion 32 and a plurality of second cleaning bodies 31. The plurality of second cleaning bodies 31 are fixed to the mounting portion 32, and the mounting portion 32 is detachably connected to the first side 11. The detachable connection between the mounting portion 32 and the first side 11 can be achieved in various ways, such as by magnetic attraction or a slotted connection. In this embodiment, when the degree of dirt in the crevices is not high, the second cleaning component 30 may not be installed, and only the first cleaning component 20 may be used to clean the surface to be cleaned, reducing resistance and improving cleaning efficiency.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
