The choice of specific words or phrases does not limit the scope of the invention, which is defined by the appended claims.

[0044] Referring now to FIG. 1, the illustrative pool cleaning tool 100 comprises a main brush 110, two side brushes 120 connecting with the main brush 110. The side brushes are used for cleaning hard-to-reach areas of pools. In some embodiments, there is only one side brush connecting with the main brush 110.

[0045] Referring to FIGS. 1-2, the side brushes are connected to the main brush 110 by two locking elements 130. The main brush comprises a main frame 111 and bristles extending from the main frame 111, each of the side brushes 120 comprises a side brush frame 121 and bristles extending from the side brush frame 121. In some embodiments, at least a part of the bristles on the side brush frame 121 extends towards an angle different from the bristles on the main frame 111.

[0046] In some embodiments, the bristle is interchangeable and can be replaced as needed to maintain optimal cleaning performance. This feature allows users to easily swap out worn or damaged bristles without the need for specialized tools or extensive maintenance procedures, ensuring the continued effectiveness of the pool cleaning tool over time. Additionally, interchangeable bristles offer the flexibility to adapt the cleaning tool to different pool surfaces or debris types, further enhancing its versatility and usability.

[0047] Referring to FIGS. 2-3, the main frame 111 has two locking pin holes 112, and each of the side brushes has a through hole 122. Each of the locking elements 130 comprises a head 131 and a pin shaft 132 connected with the head 131. The pin shaft has a restriction portion 133 with a larger size than the through hole 122 at the end of the pin shaft 132 far from the head 131, and the pin shaft 132 is made of elastic material.

[0048] In some embodiments, the restriction portion 133 is spherical or ellipsoidal.

[0049] The pin shaft 132 can consecutively pass through the locking pin hole 112 and the through hole 122 due to the elasticity of the pin shaft 132. The main frame 111 and the side brush frame 121 are therefore firmly attached under the restriction of the head 131 and the restriction portion 133. The restriction portion 133 can be pressed axially inwards by users to remove the pin shaft 132 so that the main frame 111 and the side brush frame 121 can be detached.

[0050] In some embodiments, the distance between the restriction portion 133 and the head 131 is shorter than the total length of the locking pin holes 112 and the through hole 122. The restriction portion 133 and the head 131 provide sustained compression force so the connection between the main brush frame 111 and the side brush frame 121 is stable.

[0051] In some embodiments, each of the side brush frames 121 has a counterbore extending around the through hole 122 and the counterbore is the same shape as the head 131, such that the head 131 can be fitted with the counterbore. In some embodiments, the shape of the counterbore and head 131 is square or rectangular.

[0052] In some embodiments, the shape of the counterbore and head 131 is circular. By opting for a circular design, potential issues associated with irregular shapes, such as alignment difficulties or jamming, are mitigated. The users do not have to turn the head 131 while fitting the head 131 into the counterbore, ensuring a more straightforward and user-friendly experience.

[0053] In some embodiments, the pool cleaning tool 100 further comprises a second locking element, providing an additional layer of security and stability to the connection between the main brush 110 and side brushes 120. This second locking element, similar to the primary locking mechanism described earlier, may employ a head and pin shaft configuration made of elastic material to facilitate easy attachment and detachment of the side brushes. By incorporating a second locking element, the pool cleaning tool enhances its resistance to detachment and ensures consistent performance even under varying pool cleaning conditions.

[0054] Further, the pin shaft 132 has a groove 134 at the end far from the head. In some embodiments, the pin shaft 132 has two grooves 134 and the two grooves 134 are positioned in a cross manner.

[0055] Referring to FIG. 2 and FIG. 4, the pool cleaning tool further comprises an extending assembly adjustably connected with the main brush 110. Further, the main frame 111 has an extending portion 113, and the extending assembly is adjustably attached to the extending portion 113. In some embodiments, the extending assembly is rotatably attached to the extending portion 113.

[0056] The extending assembly comprises an extending element 150 and a threaded sleeve 160. One end of the extending element 150 is adjustably connected with the extending portion 113, and the other end of the extending element 150 has a threaded structure 1512 and a hollow elastic portion 1513. The hollow elastic portion 1513 can be pressed axially inwards, such that the hollow elastic portion 1513 can clutch external extending parts such as a rod inwards. In some embodiments, the hollow elastic portion 1513 has at least a cut 1514, which enhances the elasticity of the hollow elastic portion 1513. In some embodiments, the hollow elastic portion 1513 has six cuts 1514.

[0057] In some embodiments, the extending element 150 may feature additional adjustment points or a telescoping design, providing users with enhanced flexibility in customizing the length and configuration of the extending element to suit their specific pool cleaning needs. The inclusion of additional adjustment points allows for finer control over the extension length, while a telescoping design enables smooth and easy expansion or retraction of the extending element to accommodate varying pool depths and contours. This increased adjustability ensures optimal reach and coverage during cleaning, enhancing the overall effectiveness and efficiency of the pool cleaning tool.

[0058] A near end 161 of the threaded sleeve 160 has a slightly smaller size than the hollow elastic portion 1513, while a distant end 162 has a smaller size than the hollow elastic portion 1513. From the distant end 162 to the near end 161, the threaded sleeve 160 shrinks smoothly. The threaded sleeve 160 detachably connects to the extending element 150 by the threaded structure 1512. Further, the threaded structure 1512 is closer to the middle of the extending element 150 than the hollow elastic portion 1513. Since the size of the near end 161 is smaller than the hollow elastic portion 1513, the hollow elastic portion 1513 is pressed by the near end 161 inwards so that the hollow elastic portion 1513 can clutch external extending parts such as a rod, tightly.

[0059] Referring to FIGS. 4-5, the extending element 150 comprises two connecting elements 142, each connecting element 142 has a first tooth structure 1421 and a second tooth structure 1422 with a different outside diameter from the first tooth structure 1421. In some embodiments, the outside diameter of the first tooth structure 1421 and the second tooth structure 1422 is the same. The extending portion 113 has two first internal tooth structures 1131 which can be fitted with the first tooth structure 1421. The extending element 150 has a second internal tooth structure 1511 which can be fitted with the second tooth structures 1422.

[0060] With the second tooth structures 1422 fitted into the second internal tooth structure 1511, the two connecting elements 142 can move along the axis of the the second internal tooth structure 1511. The two connecting elements 142 are configured to move between a first state and a second state. In the first state, at least one of the first internal tooth structures 1131 is engaged with one of the first tooth structures 1421, such that the extending element 150 cannot rotate related to the main frame 111 of the main brush 110; In the second state, the first internal tooth structures 1131 are disengaged with the first tooth structures 1421 respectively, such that the extending element 150 can rotate related to the main frame 111 of the main brush 110.

[0061] Further, the extending element 150 comprises an elastic element 144. The elastic element 144 is positioned between the two connecting elements 142, pushing the two connecting elements 142 toward the first state. The users need to press the two connecting elements 142 at the same time to drive the connecting elements 142 from the first state to the second state, disengaging the first internal tooth structures 1131 and the first tooth structures 1421 respectively, so that the users can adjust the angle between main brush 110 and the extending element 150. In some embodiments, the elastic element 144 is a compression spring.

[0062] Further, the two connecting elements 142 are positioned coaxially and symmetrically with respect to each other. In some embodiments, the two connecting elements 142 are positioned in a V-shape manner. The elastic element 144 and the second internal tooth structure 1511 are positioned between the two first internal tooth structures 1131. The second tooth structures 1422 has a larger outside diameter than the first internal tooth structures 1131 so the movement of the two connecting elements 142 is restricted between the two first internal tooth structures 1131. The second tooth structures 1422 has a larger outside diameter than the first tooth structures 1421, and the second tooth structures 1422 are closer to the plane of symmetry of the two connecting elements 142 than the first tooth structures 1421.

[0063] The extending element 150 further comprises two buttons 143. The two buttons 143 are connected to the connecting elements 142 respectively, and the two buttons protrude above the first internal tooth structures 1131 from two opposite directions, such that the users need to press the button from two opposite directions to adjust the pool cleaning tool 100, to prevent the pool cleaning tool 100 from being adjusted accidentally.

[0064] Referring to FIGS. 4-5, each of the connecting elements 142 has a threaded through hole 1423, each of the buttons 143 has a threaded portion 1431, and the threaded portions 1431 fit into the threaded through holes 1423 respectively.

[0065] In some embodiments, the two ends of the elastic element 144 connect to two threaded portions 1431 respectively. The elastic element 144 drives the threaded portions 1431 of the buttons 143 to drive the connecting elements 142.

[0066] Referring to FIGS. 6, each of the side brush frames 121 further has a groove 123 that fits the shape of the main frame 111, and the groove 123 is cuboid. In some embodiments, the groove 123 is cylindrical or irregular shape. The side brush frames 121 bend inwards near the groove 123, such that the side brush frame 121 can partly wrap the main frame 111.
