Problems solved by technology

[0003] After the tennis ball is opened / sealed for use, the inner tank pressure (higher than the atmospheric pressure) will gradually decrease due to leakage, causing the elasticity of the tennis ball to gradually weaken. Generally, the difference in elasticity will be felt after 1 to 2 days. A few times, after being idle for a period of time, although the tennis balls look new, they are inelastic and cannot be used any longer. Influencing the enthusiasm of tennis fans to participate in the sport
[0004] There are also products with similar functions in foreign countries, such as Tennis Ball Saver and Unique Restore Tennis Ball Pressurizer. The pressure holding effect is limited (consumer feedback is not obvious), and there is no tennis ball pressure recovery function

Embodiment 1

[0034] Such as figure 1 Shown, a kind of tennis energy pot comprises inner tube 3 and outer cover 1, and inner tube 3 outside is provided with pressurizing device, and pressurizing device comprises pressurizing tube 5, the first unit that is arranged on the inner side of pressurizing tube 5 opening end. To the valve sealing structure 2 and the locking ring 7 arranged outside the opening end of the pressurized cylinder 5, the pressurized cylinder 5 is arranged outside the inner cylinder 3, and its shape matches the shape of the inner cylinder 3. The pressurized cylinder 5, the inner cylinder 3 A pressurized gas storage space 9 is formed with the first one-way valve sealing structure 2, two second one-way valve sealing structures 6 are provided at the bottom of the inner cylinder 3, and a sealing boss matching the outer cover 1 is provided at the opening end of the inner cylinder 3 10. The other end is provided with a limit block 12 matching the first one-way valve sealing struc...

Embodiment 2

[0049] In Example 1 of the present invention, the tennis ball vitality tank can hold 3 tennis balls. If the inner cylinder and the pressurized cylinder are increased by 70mm, and the rest remain unchanged, then 4 tennis balls can be filled; Only tennis balls; under normal circumstances, it will not be strengthened if it is increased to 420mm in the inner cylinder and 410mm in the pressurized cylinder. If it is too long, it may cause difficulty in inhaling atmospheric pressure.

[0050] If there is a special need for lengthening, it can also be lengthened to a longer length. At this time, more times of repeated pulling and pressing are required to inhale atmospheric pressure.

[0051] The first one-way valve sealing structure and the second one-way valve sealing structure in the present invention can also adopt the structure of the inflating nozzle on the ball.

Abstract

The invention discloses a tennis vitality tank. The tank comprises an inner cylinder and an outer cover, a pressurizing device is arranged on the outer side of the inner cylinder, and the pressurizing device comprises a pressurizing cylinder, a first one-way valve sealing structure arranged on the inner side of the open end of the pressurizing cylinder and a locking ring arranged on the outer side of the open end of the pressurizing cylinder. The shape of the pressuring cylinder is matched with that of the inner cylinder, and a pressurizing air storage space is formed by the pressurizing cylinder, the inner cylinder and the first one-way valve sealing structure. A plurality of second one-way valve sealing structures are arranged at the bottom of the inner cylinder, and a sealing boss matched with the outer cover is arranged at the open end of the inner cylinder; a limiting block matched with the first one-way valve sealing structure is arranged at the other end of the inner cylinder; and a pressure releasing valve is arranged on the outer cover, and an air pressure color disc is arranged on the outer cover. Through manual pressurizing, the air pressure in the tank can reach about 2 barometric pressure, and the tennis air pressure obtained after tank opening is kept in the stable state, also, a tennis without elasticity can be restored to a good air pressure state, and the service life of the tennis is prolonged.

Description

technical field [0001] The invention relates to a storage device for tennis balls, in particular to a tennis ball vitality tank and its manufacturing method and usage method. Background technique [0002] Tennis is one of the most commercially valuable sports in the world.
