[0022] Shaft 1, limiting block 11, groove 12
[0023] Cleaning brush body 2, covering sleeve 21, limiting hole 211, cleaning brush unit 22, brush blade 221. Detailed Implementation
[0024] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0025] like Figures 1 to 4As shown, this utility model discloses a pool cleaning brush, which includes a rigid shaft 1 and a soft brush body 2. The shaft 1 can be assembled with the body of the pool cleaner, and the brush body 2 is glued to the shaft 1. The brush body 2 includes a covering sleeve 21 covering the shaft 1 and a plurality of brushing units 22 integrally disposed on the outer wall of the covering sleeve 21. The brushing unit 22 includes a plurality of spaced and parallel brush blades 221 in the shape of sheets.
[0026] In this invention, the cleaning body 2 and the shaft 1 of the water tank cleaning brush are bonded together with a rubber coating. That is, the cleaning body 2 and the shaft 1 are bonded together during the production of the cleaning body 2. This production method has the advantages of convenient production and high efficiency. In addition, this invention uses the various brush blades 221 of the cleaning unit 22 of the cleaning body 2 to clean the dirt attached to the water tank. The brush blades 221 have a sheet-like structure and are not easy to entangle dirt, so as to continuously and effectively clean the dirt attached to the water tank.
[0027] In embodiments of this utility model, the shaft 1 can be made of engineering plastic; to ensure the smooth rotation of the water tank cleaning brush of this utility model, the shaft 1 can be made of wear-resistant materials such as POM with a low coefficient of friction.
[0028] In embodiments of this invention, the cleaning brush body 2 can be made of plastic (such as soft PVC, TPR, or TPR) or rubber (such as silicone rubber or other synthetic rubber). The Shore hardness of the cleaning brush body 2 can be 35-60 degrees, ensuring appropriate friction when the cleaning brush body 2 contacts the bottom and walls of the pool, thus guaranteeing the cleaning effect of the pool cleaning brush and the stability of the pool cleaner.
[0029] In an embodiment of this utility model, each brush blade 221 of the cleaning unit 22 is arranged along the axial direction of the shaft 1; the thickness of the brush blade 221 gradually decreases from the inside to the outside along the radial direction of the shaft 1. This arrangement ensures high strength at the joint between the brush blade 221 and the cover, and the outermost part of the brush blade 221 is easily deformed, making it less likely for the pool cleaning brush of this utility model to get stuck during the cleaning process. Figure 4As shown, the distance from the outermost edge of the brush 221 to the central axis of the shaft 1 is defined as R1, the ratio of the distance from the innermost edge of the brush 221 to the central axis of the shaft 1 is defined as R2, the minimum thickness of the brush 221 is defined as A2, and the maximum thickness of the brush 221 is defined as A2; the thickness-to-height ratio of the brush 221 is defined as S, S=(A1+A2) / (R1-R2), S is greater than or equal to 0.03 and less than or equal to 0.2; while R1 / R2 is greater than or equal to 1.5 and less than or equal to 5; this setting allows the brush 221 to have suitable resilience and flexibility, and the friction force when the brush 221 contacts the bottom and wall of the pool is appropriate, ensuring the cleaning effect of the pool cleaning brush of this utility model and the walking stability of the pool cleaner.
[0030] In embodiments of this utility model, the brushes 221 of two adjacent cleaning units 22 are staggered (e.g., ...). Figure 1 As shown in the figure, this improves the cleaning effect of dirt and avoids dirt corresponding to the gap between adjacent brushes 221 of the cleaning unit 22 not being cleaned.
[0031] In embodiments of this invention, the covering sleeve 21 may be provided with at least two limiting holes 211, and the shaft 1 is provided with a limiting block 11 that passes through the limiting holes 211. This arrangement allows the cleaning brush body 2 and the shaft 1 to form a circumferential limiting fit and an axial limiting fit, ensuring a stable connection between the cleaning brush body 2 and the shaft 1. Furthermore, when the shaft 1 and the cleaning brush body 2 are bonded together with adhesive, the limiting block 111 can facilitate the stable positioning of the shaft 1 in the molding die of the cleaning brush body 2 and serve as an injection ejection point.
[0032] In an embodiment of this utility model, the peripheral wall of the shaft 1 may be provided with a plurality of grooves 12, which can reduce the material cost of the shaft 1.
[0033] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
