Description



CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority from Chinese Patent Application No. 201521135754.4, filed on Dec. 31, 2015, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

[0002] The present disclosure relates to the field of devices used to clean a swimming pool and more particularly, t a swimming pool brush.

BACKGROUND OF THE INVENTION

[0003] Swimming pool brushes are cleaning tools used to clean a swimming pool. A pool brush usually comprises a handle, a frame and bristles. The bristles are fixed to the bottom surface of the frame and the handle is fixed to the top surface of the frame. A handler would grasp the handle and do reciprocating motion thereof to perform cleaning with the bristles. However, the four corners of a swimming pool would often prove difficult to clean during actual usage. In prior arts, the frame is usually formed as a flat plate with bristles arranged merely on the bottom surface of the plat. Such a pool brush would be inefficient when cleaning the corners of a swimming pool, leaving persistent blots around the corners after cleaning. This will bring about poor cleaning results.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The following description is presented to enable those skilled in the art to make and use the embodiments, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art upon reading the following description, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and concepts disclosed herein.

[0017] As shown in FIGS. 1-5, a pool brush according to an embodiment comprises a brush frame 100 and a plurality of rows of bristles 300 attached on the bottom surface of the brush frame 100. The rows of bristles comprise bristles 300. Each row of the plurality of rows of bristles 300 comprises a vertical row 310 of bristles and two tilted rows 320 of bristles arranged on the two sides of the vertical row 310 of bristles. The angle between the axial line of the outermost bristle in the tilted row 320 of bristles and the axial line of each bristle in the vertical row 310 of bristles is no less than 90 degrees. A mounting socket 111 is located on the top surface of brush frame 100. A handle 200 is arranged within the mounting socket 111.

[0018] The pool brush according to an embodiment ensures the largest angle between a bristle 300 on the tilted row 320 and a bristle 300 on the vertical row 310 is greater than or equal to 90 degrees during usage. A swath using bristles 300 arranged on a flat brush frame 100 would be able to reach blots on horizontal or vertical surfaces and/or walls, but would fail to clean the corners of a pool formed at the juncture of adjacent walls. By incorporating both vertical bristles and flaring tilted bristles, and forming an angle therebetween, the four corners of a pool could be cleaned more effectively with the bristles on the tilted and vertical rows. The pool brush according to the present disclosure would therefore enable improved cleaning efficiency.

[0019] In one embodiment, the brush frame 100 includes a horizontal part 110 and two tilted parts 120 formed by curving the two ends of the horizontal part 110 upwards. The vertical row 310 of bristles are arranged, vertically on the bottom surface of the horizontal part 110, and the tilted rows 320 of bristles are arranged on the bottom surface of respective tilted parts 120. This configuration enhances the strength of connection between the horizontal part 110 and the tilted parts 120, such that life time of the pool brush may be increased.

[0020] In another embodiment, the brush frame 100 includes a horizontal part 110 and two tilted parts 120. The tilted parts 120 are formed as curvature and inserted into the two sides of the horizontal part 110. By inserting the tilted parts 120 into the horizontal part 110, assembly and disassembly of the horizontal part 110 and the tilted parts 120 becomes more convenient. Having the vertical row 310 of bristles arranged vertically on the bottom surface of the horizontal part 110 and the tilted rows 320 of bristles arranged on the bottom surface of respective tilted parts 120 could improve the cleaning efficiency of the pool brush.

[0021] The handle 200 comprises a mounting part 210 and a handling part 220 fixed aslant to the mounting part 210. During pool cleaning, a handler would grasp the handle 220 and do reciprocating motion along with the mounting part 210. As the handler grasps the handle 220, bristles 300 on the mounting part 210 would press vertically against the surface of the pool to provide improved cleaning efficiency and results.

[0022] In some embodiments, a mounting socket 111 is arranged on the surface of the horizontal part 110. The mount part 210 is embedded into the mounting socket 111. Stability of the mount part 210 could be increased using this feature.

[0023] In another embodiment, a plurality of connecting bumps 211 are arranged on a surface of the mounting part 210 which faces the brush frame 100. A plurality of connecting holes 191 are arranged on the bottom surface of the brush frame 100 in correspondence with the connecting bumps 211. Bolts are arranged at the connecting holes 101. The front ends of the bolts are screwed to the connecting bumps 211 through the connecting holes 101. The back ends are embedded into the connecting holes 101. Such configuration of bolts facilitates installation, and also avoids any contact between the bolts and the bristles 300. Usage readiness of the pool brush is improved by arranging the bolts as mentioned above.

[0024] Further, a plurality of fixing parts 221 are arranged on the two sides of the handling part 220 to support the handling part 220. The two ends of each fixing part 221 are fixed to the handling part 220 and the mounting part 210, respectively. The deployment of fixing parts 221 increases the stability of the handling part 220. Usually the force applied to the handling part 220 by the handler converges to the juncture of the handling part 220 and the mounting part 210, and tends to cause fracture at the juncture. The use of fixing parts 221 avoids such a penalty and thus increases the lift time of the pool brush. Mounting holes which penetrate the handling part 220 are also arranged on the outer surface of the handling part 220 for mounting of a prolonged holder.

[0025] Although certain embodiments have been illustrated and described herein for purposes of description, a wide variety of alternate and/or equivalent embodiments or implementations calculated to achieve the same purposes may be substituted for the embodiments shown and described without departing from the scope of present disclosure. This application is intended to cover any adaptations or variations of the embodiments discussed herein. Therefore, it is manifestly intended that embodiments described herein be limited only by the claims and the equivalents thereof.
