The working principle is as follows:
when the cleaning device is used, the cleaning block 7 is wound and clamped on the corresponding position of the net 2 through the gap between the winding clamping block 9 and the winding limiting clamping block 14, when a match training is performed, the cleaning block 7 on the net 2 is impacted through a tennis ball, so that the tennis ball extrudes the corresponding surface of the air bag 10 on the cleaning block 7 through impact force, the tennis ball is contacted with the inner side of the cleaning plate 11, the tennis ball wall is contacted and rubbed with the cleaning layer 15 on the inner side of the cleaning plate 11, the cleaning layer 15 on the inner side wall of the cleaning plate 11 limits and interferes with the lint of the tennis ball wall, and impurities of the lint of the tennis ball wall are cleaned.
When the cleaning layer 15 is made of fluff, when the cleaning layer 15 is in contact with the tennis ball wall, static electricity is generated through friction between the fluff, impurities in the fluff on the tennis ball wall are adsorbed to the contact position of the cleaning layer 15 and the fluff on the tennis ball wall through electrostatic adsorption, and after the tennis ball is separated from the cleaning layer 15, the impurities in the fluff on the tennis ball wall are cleaned under the impact force and the air resistance.
When clearance layer 15 is the plastics awl needle, can make gasbag 10 carry out the indent when tennis and gasbag 10 contact to drive clearance board 11 and carry out adaptation formula deformation, when tennis and clearance board 11 contacted, clearance layer 15 on the clearance board 11 can be to the tennis ball wall on the villus formula of bulldozing comb, thereby make the impurity in the tennis ball wall villus more easily drop.
When tennis ball strikes the air bag 10 on the cleaning block 7, the air bag 10 is recessed through the impact force, so that the airflow inside the air bag 10 is discharged outside through the exhalation holes 13 at the corresponding positions, fluff on the tennis ball wall and fluff on the inner side wall of the cleaning plate 11 are blown, and impurities in the fluff on the tennis ball wall are separated more easily.
When striking block 12 on tennis striking clearance piece 7, striking block 12 can extrude the corresponding position wall of gasbag 10 to make the extrusion pole 23 on the corresponding position extrude centering joint piece 21 through folding bag 22 shrink, thereby make the one end that restriction push rod 26 kept away from centering joint piece 21 to beat the face and carry out the perk and promote extension board 28, make the polymerization extrusion piece 29 on the extension board 28 extrude the inside wall of gasbag 10, thereby make clearance board 11 further recess to the inboard, thereby it closely contacts with the tennis to increase clearance layer 15 on clearance board 11, thereby can more deeply clear up the tennis.
When beating the tennis, through beating the custom, the user can both hands grip tightly, thereby make grab handle 6 to inwards cave in, thereby make grab handle 6 to extrude the inboard corresponding position pressure line 34, make pressure line 34 force and pull 2 net twines on the net, thereby make the net twine on the net 2 tighten in advance, thereby make the net twine pull 9 and rolling restriction fixture block 14 on the clearance piece 7, thereby make restriction piece 8 drive gasbag 10 and pull, make gasbag 10 exhaust in advance, thereby fine hair blows in advance on the tennis wall to be about to contact, thereby further improve tennis contact surface clearance intensity.
When the tennis ball is contacted with the net 2 for striking back, the cleaning block 7 and the striking block 12 on the cleaning block 7 reduce the striking force of the tennis ball, and the striking back force of the tennis ball is reduced, so that the striking back force of a user needs to be enhanced when the tennis ball is normally struck back, and the arm strength and the striking back force of the user are improved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
