Description

Technical Field

[0001] This utility model belongs to the field of sports equipment technology, specifically relating to a ping-pong ball retrieval device. Background Technology

[0002] Table tennis, as China's national sport, is loved by the general public. During training, dozens of table tennis balls are usually prepared for use. Balls missed by players scatter in various corners. After all the spare balls are used, the scattered balls are picked up from the ground. Because of the large number of balls, players need to bend over to pick them up each time, which is time-consuming and exhausting, hindering their ability to maintain stamina for subsequent training. Currently, there are some tools on the market to assist in picking up balls, such as nets attached to one end of the handle, which eliminate the need to bend over and save energy. However, these tools still require swinging the handle to retrieve the ball, which still takes time and effort. Therefore, there is room for improvement in the efficiency of ball-picking tools. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a ping-pong ball picking device that can save physical strength and improve the efficiency of picking up balls.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A ping-pong ball retrieval device includes a chassis, a collection box, a vacuum pump, a ball-collecting tube, and a partition net. A ball-suction tube is arranged on the inner wall of the chassis, with its middle section located at the upper end of the chassis and a ball inlet at its lower middle end. The collection box is located inside the chassis and has an upward-facing opening below the ball inlet. The vacuum pump is connected to one end of the ball-suction tube to generate negative pressure. The ball-collecting tube is located outside the chassis and connected to the other end of the ball-suction tube, with a cavity communicating with the ball-suction tube. The partition net is located inside the ball-suction tube, between the ball inlet and the vacuum pump.

[0006] Furthermore, the ball-collecting tube is funnel-shaped, with an elliptical large end and a small end connected to the ball-collecting tube, which widens the ball-collecting range and improves the efficiency of ball retrieval.

[0007] Furthermore, a soft sheet is provided on the lower edge of the ball-collecting tube, with the lower end of the soft sheet touching the ground to reduce gaps, so that the ping-pong ball can enter the ball-collecting tube along the soft sheet.

[0008] Furthermore, the chassis is equipped with a rod-shaped handle located on the opposite side of the ball pickup tube. The handle is tilted and connected to the chassis so that one can stand while pushing the chassis, thereby saving physical effort.

[0009] Furthermore, a battery compartment is provided at the upper end of the handle, and a battery is installed in the battery compartment to provide power to the vacuum pump.

[0010] Furthermore, a horizontal hand ring is provided at the upper end of the handle, and a button for controlling the vacuum pump is provided at the upper end of the hand ring. The vacuum pump and the button are connected by a wire, which makes it easy to push and control the vacuum pump to suck up ping-pong balls.

[0011] Furthermore, the upper part of the chassis is equipped with a storage slot for storing ping-pong balls. During the game, some ping-pong balls will be damaged. After collecting them into the collection box, the damaged ping-pong balls can be selected and placed into the storage slot.

[0012] Furthermore, the side of the chassis has an opening, through which the collection box is inserted into the chassis for easy placement and removal.

[0013] Furthermore, the bottom of the chassis is connected to several wheels to facilitate movement of the chassis.

[0014] Furthermore, a pump chamber is provided on the inner wall of the chassis. The upper end of the pump chamber is connected to the suction tube. The vacuum pump is installed in the pump chamber. The lower end of the pump chamber has an opening that connects to the outside of the chassis. A sealing cover is provided on the opening to facilitate maintenance and replacement of the vacuum pump and to facilitate cleaning of the suction tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By using a vacuum pump, negative pressure is generated in the suction tube and the ball collection tube, which pushes the machine box so that when the ball collection tube is close to the ping-pong ball, the ping-pong ball is sucked into the suction tube and falls into the collection box through the ball inlet. Compared with existing collection tools, this method saves more energy when collecting ping-pong balls and is more efficient in picking up the balls. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1-3 As shown, the ping-pong ball picking device of this embodiment includes a housing 1, a collection box 2, a vacuum pump 15, a ball picking tube 4, and a partition net 14.

[0023] A suction tube 12 is installed on the inner wall of the casing 1. The middle part of the suction tube 12 is located at the upper end of the casing 1, and the lower end of the middle part of the suction tube 12 is provided with a ball inlet 13. A collection box 2 is located inside the casing 1. The collection box 2 has an upward opening, which is located below the ball inlet 13. An opening is provided on the side of the casing 1, and the collection box 2 is inserted into the casing 1 through the opening on the side of the casing 1.

[0024] In this embodiment, the upper end of the chassis 1 is provided with a storage slot 11 for storing ping-pong balls so as to store damaged ping-pong balls.

[0025] Vacuum pump 15 is connected to one end of suction tube 12 to generate negative pressure; ball pickup cylinder 4 is located outside the casing 1 and is connected to the other end of suction tube 12. Ball pickup cylinder 4 has a cavity that communicates with suction tube 12; partition net 14 is located inside suction tube 12 and is located between ball inlet 13 and vacuum pump 15.

[0026] A pump chamber 16 is provided on the inner wall of the casing 1. The upper end of the pump chamber 16 is connected to the suction tube 12. The vacuum pump 15 is installed in the pump chamber 16. The lower end of the pump chamber 16 has an opening that connects to the outside of the casing 1. A sealing cover 17 is provided on the opening.

[0027] The suction tube 12 includes two vertical tubes and one horizontal tube. The horizontal tube is located at the upper end of the vertical tubes and is connected between the two vertical tubes. The vertical tubes and the horizontal tubes are attached to the front side wall, upper side wall and rear side wall inside the housing 1. One vertical tube is connected to the outside of the housing 1 and to the ball pickup tube 4. The other vertical tube is connected to the pump chamber 16. In this way, after the vacuum pump 15 is working, a negative pressure can be generated in the suction tube 12 so as to suck in the ping-pong ball.

[0028] To achieve a wider ball-collecting range, the ball-collecting cylinder 4 can be funnel-shaped, with an elliptical larger end and a smaller end connected to the ball-collecting tube 12. Ping-pong balls within the range opposite the larger end will be drawn into the ball-collecting cylinder 4. Additionally, a flexible sheet 5 is provided along the lower edge of the ball-collecting cylinder 4, with its lower end resting against the ground. The sheet 5 can be made of rubber, providing flexibility and minimizing damage when the casing 1 is moved to uneven surfaces.

[0029] To facilitate the movement of the ping-pong ball retrieving device, several wheels 3 are connected to the lower end of the housing 1. A rod-shaped handle 6 is mounted on the housing 1, located on the opposite side of the ball-collecting tube 4. The handle 6 is inclined to the housing 1, allowing for manual pushing of the housing 1 and facilitating the ball-collecting tube 4 to reach under the table to retrieve ping-pong balls. Furthermore, a battery slot 9 is located at the upper end of the handle 6, housing a battery 10. A horizontal hand ring 7 is also located at the upper end of the handle 6, with a button 8 controlling the operation of the vacuum pump 15 at the top. The vacuum pump 15 is connected to the button 8 via a wire.

[0030] During ball retrieval, after pushing the machine 1 to the location of the ping-pong balls, align the ball-collecting tube 4 with the ping-pong ball to be picked up, press the button 8 on the upper end of the handheld ring 7 to start the vacuum pump 15. Negative pressure is generated in the suction tube 12, and the ping-pong ball will enter through the ball-collecting tube 4 and be sucked into the suction tube 12. When the ping-pong ball reaches the ball inlet 13, it cannot pass through to the side of the vacuum pump 15 due to the obstruction of the partition net 14, and finally falls into the collection box 2. When the collection box 2 is full of ping-pong balls, it can be removed from the machine 1 for training use. Picking up ping-pong balls in this way can save the physical strength of the ball-collecting personnel and has a high ball-collecting efficiency.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
