Description

Technical Field

[0001] This utility model relates to the field of tennis ball collection technology, and in particular to an automatic tennis ball collection device. Background Technology

[0002] Tennis is a ball sport, typically played between two singles players or two pairs, with the goal of preventing opponents from effectively returning the ball to their own players. However, for tennis enthusiasts, especially athletes, frequently retrieving tennis balls scattered over a large area during training is a time-consuming and laborious task. Existing tennis ball collection devices mostly use a spindle-shaped ball-holding structure, with its outermost end in direct contact with the ground, which easily causes wear and tear on the spindle-shaped ball-holding structure, affecting its lifespan.

[0003] A search revealed that patent CN203663379U discloses a tennis ball collection device for tennis training. Specifically, this invention addresses the problem that tennis ball collection in tennis courts is currently done manually, which not only wastes the athletes' energy but also results in low collection efficiency.

[0004] Based on the aforementioned patents, the existing technology has the following shortcomings: the existing technology uses a negative pressure adsorption method to collect tennis balls, which can only collect one tennis ball at a time, resulting in low collection efficiency of the entire device. Moreover, during the collection process, the entire device needs to be manually pushed to bring the tennis ball into the suction channel and make contact with the tennis ball. This operation process is not flexible and is inconvenient to use. Therefore, there is an urgent need to design an automatic tennis ball collection device to solve the above problems.
